Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to an operation control device for vehicles such as buses and trains, and in particular automates various controls necessary for the operation of vehicles, reduces the labor burden on drivers, and at the same time provides services to passengers. The present invention aims to provide an operation control device that can also improve the performance of vehicles.

<Background of the Invention> In recent years, it has become common for buses to be operated by one driver. In the case of a one-man system, the driver must not only operate the vehicle but also collect tolls, which places a considerable burden on the driver.

On the other hand, from the passenger's perspective, improvements in bus service are desired. For example, at a bus stop, destination guidance is provided by voice to the outside of the vehicle immediately before the vehicle stops. The train will operate according to the scheduled timetable. Respond by voice to the passenger's signal to descend.
etc., and it is currently impossible to burden the driver with these demands; rather, it is desired to reduce the driver's labor.

<Objective of the Invention> The present invention aims to provide a vehicle operation control device that can improve service to passengers and reduce the driver's labor.

<Summary of the Invention> In this invention, control data necessary for the operation of a vehicle and distance data for executing the control are stored in a writable/readable memory RAM 113, and the CPU 11 stores them in the memory. It is intended to be constructed so that control data is read out sequentially in correspondence with the travel distance of the vehicle, and all necessary controls for the route can be performed automatically.

Therefore, in this invention, the control data necessary for passenger operation, the distance data for executing the control data, voice destination guide announcements, voice response to a drop signal, data necessary for on-time operation, etc. are determined in advance by the name of the stop on the line. These control data and the distance data for executing the control data are transferred to the write/read memory RAM 113, and destination guidance information and voice response information are recorded on a recording medium for broadcasting, such as the beginning of a magnetic tape. etc. are transferred to the writable/readable audio memory RAM 119. Control data is stored in RAM11 according to the distance traveled by the vehicle.
3. The audio information can be sequentially read out from the RAM 119 and all necessary controls for the route can be automatically performed. Therefore, for example, it is possible to control left and right turns using turn signals at the necessary positions, and also broadcast destination guidance etc. at the necessary positions, and when arriving at a stop, the destination guidance can be broadcast to the outside of the vehicle. Also, the error value between the predetermined travel time and the actual travel time is calculated, and the error value is displayed to notify the driver.

<Conventional Example> A conventional example is shown in a part of FIG. 101 in the diagram
indicates an existing in-vehicle guidance announcement system. This in-vehicle guidance broadcasting device 101 includes a tape player 102, an audio amplifier 103a, and a tape stop signal amplifier 103b.
, selector switch 104 , and in-car speaker 105
and an external speaker 106.

The tape 107 used in the tape player 102 has broadcast contents 201a, 201 as shown in FIG.
In addition to the track 202 on which the tapes 201b, 201c, . . . Reference numeral 108 denotes a tape drive control device, which performs an operation of stopping the running of the tape 107 when an automatic tape stop signal 203 is applied.

Conventionally, a manual switch is connected to this tape drive control device 108, and when the driver manually operates this manual switch, the tape 107 is started, and the content 201 recorded on the track 202 is started.
Play one of a, 201b, 201c, ...,
This is broadcast through the in-car speaker 105, and the next stop name is broadcast.

Furthermore, when the passenger door is opened, the selector switch 104 connects the amplifier 103a to the external speaker 106 in conjunction with the opening of the door, and the tape player 102 is activated to play a "numbered ticket" from the broadcast track 202, for example. Please do not bring dangerous items with you.'', etc., will be announced.

Therefore, the driver is required to operate a switch to broadcast the name of the next stop at an appropriate driving position after leaving the stop. Further, even though the boarding guide broadcast always has the same content, it must be played back from the tape 107, which requires a long tape 107. In addition, when broadcasting boarding information, there is a request to broadcast the destination name, such as "This bus is on the XX line," but broadcasting this destination name would require a longer tape length, and it would fit into one roll of tape. One line will not be able to accommodate the required content. For this reason, it has the disadvantage that the destination name cannot be broadcast.

As described above, conventionally, the workload of drivers is large and the improvement of service to passengers has been hindered.

In contrast, the present invention aims to provide a vehicle operation control system that can eliminate both of these obstacles, reduce the workload of the driver, and improve the service to passengers.

<Embodiments of the Invention> In FIG. 1, 109 indicates this operation control device. This example shows a case where the operation control device is configured by a microcomputer. As is well known, a microcomputer houses a central processing unit (hereinafter referred to as CPU) 111 and a program that operates this CPU 111 in a predetermined order.
RAM 112 and immediately readable memory, so-called RAM 113, which stores sequentially captured data.
and an input port 114 for taking in data are the main components.

In this invention, in addition to the main components of the microcomputer, a counter 115 for accumulating the distance traveled is provided, and this counter 115 is connected to the travel pulse generator 11.
It is configured to count the running pulses input from 6. The counter 115 is actually
Although it is possible to reuse a part of RAM113,
Here, in order to simplify the explanation, the counter 115 will be explained separately.

The driving pulse generator 116 may be one that generates pulses in conjunction with the rotation of a wheel or a propeller shaft, for example, and is configured by, for example, attaching a turnout to a wire that transmits rotation to a speedometer, and attaching a rotation sensor to this turnout. can do. For example, assuming that 20 pulses are obtained during one rotation of the wheel, and the diameter of the wheel is 1 meter, the distance traveled can be detected with a resolution of about 16 cm per pulse. Therefore, by having the counter 115 integrate the travel pulses, the travel distance can be integrated with an accuracy of about 16 centimeters. The mileage data accumulated in the counter 115 is input to the CPU 111 through the input port 114, and compared with data stored in the register 118 (described later). When a match is detected, the control information is extracted from the RAM 113 to the register 117 It is configured to control various devices.

It is assumed that the RAM 113 stores in advance various control information necessary for the operation of the vehicle and distance information for executing the control information. This control information and distance information are recorded at the beginning of the in-vehicle guide magnetic tape 107 used for the route, and at the start of operation, this information is reproduced and transferred to the RAM 113 for use.

In addition to the above-mentioned control information and distance information, the information transferred from the magnetic tape 107 to the control device 109 includes audio information for destination guidance broadcasting and boarding guidance. For example, the necessary audio information is stored in the audio-only RAM 119, and necessary audio information is read from the audio-only RAM 119 as needed, and the read output is sent to the DA converter 12.
1 is converted into an analog signal, the analog signal is amplified as an audio signal by an amplifier 103a, and the sound is emitted from a speaker 105 or 106.

It is assumed that the control information distance information and audio information are recorded as serial digital signals at the beginning of the magnetic tape 107, for example, and are reproduced and taken into the control device 109. For example, the serial digital signal is made up of 8 serial bits as one unit, and the control information and distance information are, for example, as shown in FIG.
It is assumed that the latter 5 bits are divided and used as distance information 302.

Further, as for audio information, all 8 bits are used as audio information, as shown in FIG. For example, audio information such as "This car is in the XX line. Please take the numbered ticket." is sampled at a frequency of about 4KHz, and this sampled instantaneous analog value is converted from AD to AD. Consider the case where parallel digital codes are converted into serial digital codes and recorded on the magnetic track 202 of the magnetic tape 107. Note that when audio signals are recorded on the magnetic tape 107 and transferred to the RAM 119,
It can also be configured to perform AD conversion.

Control information 301 and distance information 302 can be created, for example, as follows. First, a model driver drives the bus for each bus route, and records the distance data between each stop and the operation timing of each part. In other words, after leaving the first stop, at what distance according to the route should the name of the next stop be announced, at what distance should the left or right turn signal be issued, and how many meters before arriving at the next stop? When the car issues a left turn signal to enter the stop from the position, and when the car stops at that stop, the distance value from the previous stop, that is, the cumulative value of driving pulses, etc. are recorded. The distance value between each stop shall be accumulated using each stop as a base point. In this way, even if there is a difference in tire pressure between the model driving vehicle and another vehicle, for example, and there is a difference in the distance traveled per driving pulse, the error value based on that difference will be Since it is reset each time the driver arrives at each stop, it is not accumulated and the error value can be reduced.

The results of this model operation are converted into digital codes representing control information and distance information, and the digital codes are converted into serial digital codes to be printed on the magnetic tape 1.
Recorded on 07.

FIG. 5 shows an example of the operation of each part in a model operation. In FIG. 5, A indicates a running pulse. 50
1 indicates the departure stop, and 502 indicates the arrival stop. FIG. 5B shows an example of how a direction indicator is operated. After leaving the stop 501, for example, at the 1000th driving pulse P ₁ , operate the turn signal to indicate a right turn, and from the 1000th driving pulse P ₁ to the 200th pulse P ₂ , indicate the direction. For example, at the 4000th travel pulse P ₄ from departure, the next stop is 50.
This shows a situation where a left turn instruction is issued to enter 2, and the direction instruction is returned to the original direction when the vehicle comes to a stop. FIG. 5C shows the state of the next stop name broadcast operation. This example shows a situation where an operation is performed to broadcast the name of the next stop at the 1500th travel pulse _P3 after leaving the stop 501.

If, for example, "1, 0, 0" is assigned as the right turn operation signal of the turn signal based on such a model driving example, "1, 0, 0" will be assigned as the control signal.
Further, a digital code "0, 0, 1, 0, 0" representing the running pulse _P1 is created and recorded on the magnetic tape 107 as a serial code. Digital codes created as this distance information “0, 0, 1, 0,
For example, if we use the upper 5 bits of a hexadecimal counter, this digital code ``0, 0,
1, 0, 0" is 1024 pulses in decimal notation, but 24
It is assumed that the pulse portion is ignored as an error. In this way, if the upper 5 bits of the hexadecimal counter are used as distance information, a maximum of 7936 travel pulses can be counted, and the minimum resolution is the lowest bit every time 256 travel pulses are input. This is the resolution where H logic stands at _B4 . This minimum resolution is based on the above-mentioned conditions of the traveling pulse generator 116.
In other words, if the diameter of the wheel is 1 meter and 20 pulses are generated per wheel, the minimum resolution is approximately 41 meters. Therefore, an error of 141 meters occurs, but the timing of various operations while driving is
A deviation of around 40 meters will not result in a large error. Also, the maximum distance that can be expressed under this condition is approximately 1270
meters. The average distance between bus stops in urban areas is approximately 500 meters, so being able to count a distance of 1,270 meters is sufficient for practical use on bus routes in urban areas. If there is a section where the distance between bus stops exceeds 1270 meters, the number of stages of the counter that counts the running pulses during the model operation may be increased, and the number of bits of the digital code used as distance information may be increased.

At the end of the right turn, create a digital code such as "0, 0, 0" to return the control information 301 to its original state,
This digital code "0, 0, 0" and distance information "1, 0, 1, 0, 0" representing the 1200th run are created. This digital code is 1024 in decimal
+256=1280 pulses, but 80 pulses are considered as an error.

For example, "0, 0, 1" is assigned as the operation signal for the in-vehicle guidance announcement of the next stop name. According to the model driving, this in-vehicle guidance announcement is made at the 1500th driving pulse, so the distance information should be "0, 1, 1, 0, 0" (1536 in decimal), which is close to 1500. This is converted into a serial code and recorded on magnetic tape.

For example, the right turn operation is performed using digital codes "0, 1,
0" is assigned. When operating a right turn, the driving pulse is 4000.
Since it is the th state, the digital code "0, 0, 0, 0, 1" (decimal number
4096 pulses (representing 4096 pulses) are created and recorded on the magnetic tape 107 as a serial code.

In the above-mentioned control information 301, reset information for resetting the counter 115, for example, "1, 1, 1" is inserted together with distance information when the vehicle stops at the next stop during the model driving. This reset information is used to automatically reset the counter 115 when passing through a bus stop without stopping.

In this way, the distance information close to the operation timing of each model drive is digitally encoded, converted into a serial digital signal with each control information, and then recorded on the magnetic tape 1.
07 in sequence.

Control information 301 recorded on magnetic tape 107
and distance information 302 are played at the start of operation,
It is transferred to an immediately readable memory, ie, RAM 113, through an input port 114. The information 301 and 302 may be transferred at once for all sections of the bus route, or the information for the next section may be transferred after each stop name is recorded each time one section is passed. Control information and distance information may also be recorded. Here, all the control information 301 and distance information 30 necessary for the route at the start of operation are displayed.
2 is transferred at once and all information is loaded into the RAM 113.

The order of the information recorded on the tape 107 is sequentially loaded into the RAM 113 from the first address to the next address. The captured control information 301 and distance information 302 are sequentially fetched into registers 117 and 118 in the order of addresses. That is, the control information 301 is taken out to the register 117, and the distance information is taken out to the register 118. Here, when the counted value of the counter 115 matches the distance information 302 stored in the register 118, the control information 301 stored in the register 117 is
It is decoded by the CPU 111, and each device is controlled based on the decryption result.

In FIG. 1, reference numeral 122 indicates a direction indicator, and when the information stored in the register 117 is direction indicator information, the CPU 111 uses the direction indicator 1.
A signal specifying the interface 123 for controlling the vehicle 22 is output, and a right turn or left turn instruction is controlled at a predetermined travel position.

When the distance information stored in the register 118 and the count value of the counter 115 match, the read address of the RAM 113 is incremented by one, the control information 301 and distance information 302 of the next address are read out, and the control information 301 is stored in the register 117. and the distance information 302 is stored in the register 118, respectively.

Reference numeral 124 indicates an interface for controlling the start-up of the tape player 102. This interface 124 stores control information for performing in-vehicle guidance broadcasting in the register 117, for example, "0, 0, 1", and the counter 115 and the register 118.
When the distance information matches, the tape drive control circuit 1
A start command signal is given to 08 to start the playback device 102 and broadcast the in-car guidance for the next stop. 1
Reference numeral 25 indicates an interface for controlling the changeover switch 104. This interface 12
5 operates to select the speaker 105 of the switch 104 when the tape player 102 is in operation.

The distance traveled by the bus as described above is accumulated, and the accumulated value and distance information 30 stored in the RAM 113
It will be understood that when the two values match, the direction indicator 122 and the tape player 102 are automatically controlled by the control information 301.

<Description of the audio instantaneously readable memory 119> Next, the audio signal reproduced from the audio RAM 119 will be described. As described above, this audio RAM 119 stores audio information that repeatedly broadcasts the same content, such as destination guidance. Examples of this audio information include, in addition to the destination information announcement, audio with content such as ``Please take a numbered ticket.'' ``Please do not bring dangerous goods.'' ``The next stop.'' ``The train is departing.'' The AD conversion value is serially digitally encoded and recorded at the beginning of the magnetic tape 107. It is played back only once at the start of operation and transferred to the audio RAM 119.
Store it in 9. During this storage, serial digital codes are converted to parallel digital codes and stored in RAM 11.
9 addresses as parallel digital codes.

By adopting such a method of transferring voice information to the RAM 119 and a method of recording it in the RAM 119, it is possible to manufacture voice synthesis ICs at a lower cost than when manufacturing ICs for each route.

The audio information taken into the RAM 119 is stored in a designated storage area for each word and phrase, and the storage area is designated and read out as needed.

For example, when the push button 126 for alighting signal is operated by a passenger while driving, the CPU 111 enters an interrupt operation and reads out the area where the words "Next stop" stored in the voice 119 are stored due to the interrupt. ,this
Amplifier 103 through DA conversion and filter 127
supply to a.

On the other hand, it is desirable to broadcast destination guidance to the outside of the vehicle immediately before the vehicle stops at the stop. For this purpose _, the left turn operation position pulse _P4 , which indicates entering the stop explained in FIG. After the position is detected, it is detected that the brake pedal 128 has been operated, for example, and when the two conditions match, the vehicle speed detection program is executed. This vehicle speed detection program detects when the number of running pulses input per unit time becomes less than a predetermined number, and performs an operation to detect the state immediately before stopping at a stop. For this purpose, for example, counter 1 is set every unit time.
What is necessary is to monitor the increase in the count value of 15 and detect when the increase becomes less than a predetermined value.

When the vehicle speed detection program detects a state immediately before the vehicle stops at a stop, the CPU 111 reads the storage area of the audio RAM 119 that stores the destination guidance broadcast. Along with this, interface 125
controls the switch 104 to select the external speaker 106.

In this way, the vehicle speed detection program detects the state immediately before the vehicle stops at the stop, and broadcasts the destination to the outside of the vehicle. Therefore, a person waiting for a bus at a bus stop can see where the bus is going even if he or she overlooks the bus's destination display. This is especially convenient for visually impaired people.

When the bus stops at a stop and the door is opened, the door's open signal not only broadcasts destination information, but also
The CPU 111 operates so that the area in which the phrases ``Please take a numbered ticket'' and ``Please do not bring in dangerous goods'' is also read out, and these boarding instructions are broadcast together with the destination information broadcast. Furthermore, when the vehicle speed becomes completely zero, the CPU 111 detects that the bus has stopped, and as a result, the counter 1
15, calls the read address of the RAM 113, and reads out the first information required in the next section.

When the door closes, the first running pulse is counter 1.
15, the CPU 111 detects that the bus has started moving, and the CPU 111 audio RAM 11
An operation is made to read out the area in which the words ``The train is departing.'' No. 9 is stored, and the words ``The train is departing.'' are broadcasted to the inside and outside of the vehicle to warn passengers and those outside the vehicle.

The audio information 401 thus captured in the audio RAM 119 is read out from a required storage area as required by the passenger's command operation for descending or by the vehicle speed detection means, and is used to broadcast stop and release information or destination guidance. These broadcasts are unprecedented broadcasting services, and will improve services for passengers.

<Explanation of passing the bus stop> If there are no passengers getting off at the next stop, and if there is no one waiting at the stop, the bus will pass through the bus stop without stopping at that stop. At the time of passing the stop, by detecting a match of the previous distance information,
The address is updated and the reset information "1, 1, 1" and the distance information representing the stop position are read from the RAM 113, and this is read out from the register 117 and 1.
It is stored in 18. Therefore, the distance information 302 stored in the register 118 matches the value of the counter 115 before and after passing the stop (this can be considered to be a slight error between the model driving time and the time of the model driving), and this match causes the value of the register 115 to match. The reset information “1, 1, 1” stored in CPU 117 is
, and the counter 115 is reset.

Therefore, the counter 115 counts the travel pulses again from the initial value, and performs various controls according to the control information 301 at each travel distance position set in the next section. Note that when the vehicle passes a stop, the vehicle speed detection program is not executed and the door is not opened or closed, so the CPU 111 uses the audio RAM 1 in that state.
19 is read and boarding guidance and departure guidance are not performed.

<Other control devices> The basic configuration and effects of the present invention will be understood from the above. In this embodiment, a case is shown in which the system is configured to perform various controls necessary for the operation of the bus.

One way is to control an indicator that alerts following vehicles that you are entering a stop. In FIG. 1, 129 indicates a display mounted at the rear of the bus. This can be done by, for example, turning on a light to display the message "Entering a bus stop" to the following vehicles, informing them that the bus is entering the bus stop. This display 1
Conventionally, the 29 has been operated in conjunction with a left-turn turn signal, but this has the disadvantage that whenever a left-turn instruction is given, the message "Entering at a stop" is always displayed. However, if this invention is applied, the distance position at which this display 129 is to be operated can be determined in advance.
By storing it in the RAM 113, the display 129 can be operated only when entering a bus stop. Reference numeral 131 indicates an interface for operating the display 129.

<Description regarding on-time operation indicator> 132 indicates an on-time operation indicator. When the train arrives at the next stop, this display shows whether the actual schedule matches the scheduled timetable, or whether it is ahead or behind. The time required for each section of the scheduled timetable is shown along with the various data listed above.
It shall be stored in the RAM 113 and also provided in the clock means 133. This timer 133 is reset each time the train departs from a stop, and measures the passage of time from the initial value, and when the train arrives at the next stop,
The time value of the timer 133 is compared with the standard required time stored in the RAM 113, and the delay or advance is displayed on the display 132. 134 is an interface for connecting the display device 132 to the CPU 111.

<Explanation regarding the control of the destination guidance display> Conventionally, the destination guidance display has been manually operated by the driver so that the information corresponding to the route being operated is displayed. can also be automated.

In other words, control information regarding the destination guide display is recorded on the magnetic tape 107, and this control information is
The destination guidance display data is transferred to the RAM 113, and further transferred to the register 135, and the destination guidance display 136 is controlled based on the data value stored in this register.

Destination guidance display 136 can be of various types. For example, in the case of a conventional system that moves subtitles for display, a digital code assigned to each destination is stored in the register 135, and the digital code and the subtitle display position detection means provided on the display 136 are transmitted. The movement of the subtitles may be controlled until the digital codes match, and the movement of the subtitles may be stopped at the time they match.

In addition, as another new type of display device, for example, a large number of liquid crystal cells or other dot display elements are attached to the display surface, the dot display elements selectively display dots, and the destination name is displayed by the dot display. You can also do that. In this case, static display and dynamic display can be considered. In the case of static display, the register 135 has a capacity equal to the number of dot display elements of the display 136, all the amount of data necessary for display is stored in this register 135, and the output of the register 135 is used to display the dot display elements. control. In addition, in the case of dynamic display, for example, the RAM 113 stores all the data necessary for displaying the destination, and the register 135 has a capacity for one horizontal line of the display 136, for example, so that the data is displayed for each line. It is only necessary to transfer the data and display the dots on the display in a time-divided manner.

<About proximity detector control> When the bus departs or turns left, the driver must check whether there are people or other vehicles on the left side of the bus. In such a case, it is conceivable to operate the proximity detector 137 using a high-frequency oscillator to prevent failure accidents.

Therefore, when the left turn direction indicator operates and when the vehicle starts, the proximity detector 137 can be automatically operated by the CPU 111 to detect obstacles in advance. Note that 138 indicates an interface for connecting this proximity detector 137 to the CPU 111.

<Effects of the Invention> As described above, according to the present invention, various operations performed by a bus driver can be controlled in a predetermined order in conjunction with the travel distance. Therefore, the bus driver can concentrate only on driving while the bus is running, thereby preventing accidents and reducing labor.

However, when the voice RAM 119 is added to the control, various guidance can be given to the passengers by voice. As a result, it is possible to realize an unprecedented service in which destination guidance can be provided by voice, and its effects are significant in practical use.

Furthermore, in this invention, the integrated value of the counter 115 is reset to zero each time the vehicle stops at or passes a stop, so the number of pulses generated by the travel pulse generator 116 for the distance traveled varies depending on the vehicle. However, the error in the control position relative to the traveling distance is not accumulated. Therefore, errors in controlling the control position for each section can be reduced.

In the above description, a bus has been described as an example of a passenger, but it is easy to understand that the present invention can be applied to other vehicles such as trains.
