Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a bus operation control system for controlling bus operation in mixed traffic.

Conventionally, this type of apparatus has been shown in FIGS. 1 and 2.

In Figure 1, A and B are the ends of the road section where bus operation is controlled, 1 is the display installed near the A and B ends, respectively, and 2 is the bus display installed near the A and B ends, respectively. A bus sensor (hereinafter referred to as a sensor) that detects the presence or information such as vehicle number, route, up/down, etc., and 3 is a control device for controlling each display 1 based on the sensing signal from each sensor. ,
4 is a bus entering the A-B section from the A end.

FIG. 2 shows an example of the display 1, where 5 is an operation indicator light, 6 is a sensing indicator light that indicates that a signal transmitted from the bus 4 has been detected, and 7 is a sensor 2.
Alternatively, a failure indicator light indicating that the control device 3 has failed; 8 is a support to which the indicator 1 is attached;

Next, the operation will be explained. In the road section where it is necessary to control the operation of bus 4, it is difficult for buses to separate from each other, but it is possible for buses and general vehicles to separate from each other, as shown in Figure 1A.
-B section. When the bus 4 comes to the A end, the sensor 2 at the A end senses it and sends the information to the control device 3. The control device 3 has already connected the bus from the other end B to A.
- Check whether the bus is entering the B section, and if there is no bus that can enter immediately, turn on the operation indicator light 5 of the display 1 at the A end, and make the bus 4 at the A end enter the A-B section. If there is a bus that enters immediately from the opposite direction, that bus exits the A end, and the sensor 2 of the A end
detects the exit and the exit information is sent to the control device 3.
As a result, the operation indicator light 5 at the A end is turned on, and then the bus 4 at the A end is allowed to enter.

Also, when sensor 2 at end A detects bus 4,
The sensing indicator light 6 of the end display 1 lights up, so if it is lit and the operation indicator light 5 and the fault indicator light 7 do not light up, the operation indicator light 5 is turned on even though there is no fault. Since entry is prohibited, the driver of Bus 4 can determine that there is a vehicle approaching from the opposite direction immediately.

Furthermore, if the operation indicator light 5, sensing indicator light 6, and failure indicator light 7 at the A end are not all lit, it can be determined that the sensor 2 at the A end has not detected the sensor 2 for some reason. In this case, if the bus 4 is equipped with an on-vehicle transmitter for a sensor, it can be determined that the transmitter is out of order, and if the sensor is only on the road, it can be determined that there is a lack of sensing. Further, when the failure indicator light 7 is lit, it can be determined that there is a failure in the roadside device.

Furthermore, various types of sensors 2 used here are already known for detecting vehicles, and these are utilized. Some of these sensors use light, which can detect cars only on the road, and some use ultrasonic waves, but if you only need to detect cars, this type of sensor can be used. .

In addition to detecting the presence of a vehicle, if information such as vehicle number, route, up or down direction is required, radio waves, etc.
An in-vehicle transmitter using guided radio waves and a roadside receiver are installed, and the necessary information is transmitted from the in-vehicle transmitter.
It is possible to use a radio wave type or guided radio wave type sensor that demodulates and uses the information with a roadside receiver.

The conventional bus operation control system is configured as described above, and its display 1 displays as described above. Therefore, when the bus 4 arrives at one end and enters the road section A-B, if the operation indicator light 5, the sensing indicator light 6, and the failure indicator light 7 do not light up, the equipment on the road is normal. but,
It can be determined that there is a sensing error in the sensor due to some reason, or that the in-vehicle transmitter of bus 4 is malfunctioning. In this case, if the system is equipped with an in-vehicle transmitter, switch to a backup device, or if the system uses road sensors, wait for the driver to report or an oncoming vehicle passes. Immediately after that, it is necessary to take measures such as entering the A-B section.
As a result, there were disadvantages such as an increase in the cost of equipment such as the above-mentioned spare equipment and an increase in bus separation losses.

This invention was made to eliminate the drawbacks of the conventional ones as described above, and by adding a manual switch device that transmits a signal equivalent to the sensor signal to the control device, smooth and safe operation control can be achieved. The purpose is to provide a bus operation control system that can perform the following tasks.

An embodiment of the present invention will be described below with reference to the drawings.

What differs from the conventional one is that a switch device 9 is additionally installed.

1 is a display device equipped with an operation indicator light 5, a sensing indicator light 6, and a failure indicator light 7; 2 is a sensor; 3 is a control device for controlling the display device 1 according to a sensing signal from the sensor 2; 4; is a bus.

Reference numeral 9 denotes a switch device that is manually operated by the driver of the bus 4 after getting off the bus when the sensing indicator light 6 of the display device 1 is not lit even when the bus 4 passes in front of the sensor 2. This is attached to device 1.

Next, the operation will be explained.

When the bus 4 comes to the A end, normally the sensor 2 at the A end senses the bus 4 and sends a sensing signal to the control device 3. Based on that, the control device 3
First, turn on the sensing indicator light 6 of the indicator 1 at the A end,
The driver is informed that the arrival of the bus 4 has been confirmed on the roadside, and the lighting of the operation indicator light 5 is controlled. In that case, if there is no bus that has already entered the A-B section from the opposite B end, the operation indicator light 5 at the A end is turned on to instruct the bus 4 to enter. Also, if there is a bus that has already entered the A-B section from the opposite B end, that bus exits the A-B section from the A end, and when exiting, the sensor 2 at the A end detects the exit. Then, the operation indicator light 5 at the A end is turned on to instruct the bus 4 to enter.

Therefore, the driver of the bus 4 at the A end turns on the operation indicator light 5 after the sensing indicator light 6 of the display device 1 at the A end lights up.
If the failure indicator light 7 does not light up, it can be determined that the oncoming bus is approaching, and the bus waits at the A end.

Furthermore, if the A-end sensing indicator light 6, operation indicator light 5, and failure indicator light 7 do not all light up, it can be determined that the sensor 2 at the A-end does not detect the sensor 2 for some reason. In this case, if the bus 4 is equipped with an on-vehicle transmitter for a sensor, it can be determined that the transmitter has failed, and if the sensor is only on the road, it can be determined that the sensor is not being detected.

In this case, in case of an emergency, the driver gets off the vehicle and manually operates the switch device 9 installed on the road to transmit a signal equivalent to the sensing signal of the sensor 2 to the control device 3, and the display is displayed. Control 1.
This can prevent, for example, the bus 4 from accidentally entering and colliding with an oncoming vehicle in the A-B section.

In addition, if the sensor 2 is out of order, the bus 4 cannot be sensed, so normal operation control will not be executed. However, temporarily, a person will be placed at the switch device 9 to complete the repair of the sensor 2. It is also possible to perform operation control by manually operating the switch of the switch device 9 to control the display 1 when a bus approaches.

Figure 5 shows the display 1, sensor 2, and switch device 9.
3 is a block diagram showing an example of the flow of signals between the control device 3 and the control device 3. FIG.

In FIG. 5, normally when the bus 4 is sensed by the sensor 2, the sensor signal is sent by wire to the demodulator 31 of the control device 3, and its signal input a is input to the CPU 35 via the OR circuit 34. After calculation processing,
The display 1 is controlled via the display control circuit 36.

In addition, when the switch device 9 is operated, there is a failure of the sensor 2 or the in-vehicle transmitter is broken, and when the driver gets off the vehicle and presses the push button switch 91 of the switch device 9 installed on the road. , a closed circuit is formed and the relay drive circuit 32 operates,
The pulse generating circuit 33 operates with the output, and a signal input b equivalent to the signal input a in the normal case is input to the OR circuit 34, and the display 1 is controlled in the same way as in the normal case.

Here, the OR circuit is a circuit that operates if either one of the signal inputs a and b is present.

In the above embodiment, the two sensors 2 at both ends A and B were provided so as to be able to detect both the entry and exit of the bus 4, but as shown in FIG. It is also possible to provide two entry sensors 21 and two exit sensors 22.

In addition, since the switch device 9 can be operated only when the bus 4 is waiting near the display device 1, it is provided so as to be attached to the display device 1; however, the switch device 9 is attached to the display device 1. The same effect as in the above embodiment can be obtained even if it is provided independently at a suitable position without having to do so.

As described above, according to the present invention, a switch device is installed in a conventional system, so that when all the indicator lights are not lit, the bus driver can operate the switch device to The presence can be reliably notified to the control device 3,
This makes it possible to accurately judge the situation and take appropriate measures, thereby facilitating efficient and safe operation control.
