[0002]

2. Description of the Related Art A conventional train monitoring system is realized with a configuration as shown in the block diagram of FIG. A monitor device 1 is installed in each vehicle to constantly monitor the vehicle state. Each monitor device 1 is connected by a transmission line 5 and displays the vehicle status on a display 8 installed in the leading car.

In one vehicle, in addition to the monitor device 1, each vehicle control device, SIV device (auxiliary power supply device) 2, VVVF device (main power supply device such as an inverter device) 3, ATS-P device (automatic train with running pattern) Stop device) 4 is installed. The monitor device constantly monitors the state and failure of each vehicle control device through digital and analog inputs.

Further, the monitor device 1 includes a SIV device 2, V
The failure signal 6 is taken in from each of the VVF device 3 and the ATS-P device 4. Each monitor device 1 monitors the state of the failure signal 6 from the vehicle control device, detects a trigger of failure occurrence, and stores the state of each vehicle control device before and after the trigger as a record.

The operation of storing the failure signal in this case is shown in FIG.
It is performed based on the record storage sequence shown in. The monitoring device 1 (S1) for each failure recording sampling period,
The failure record (digital or analog state) of the vehicle control device is transferred (stored) to the work buffer (S2). At the same time, it is determined whether a failure record is being created (S3), and if the failure record is being created, it is transferred (stored) to the work buffer as a failure record (S4).

In S3, when the failure record is not being created, the trigger of the failure signal 6 is monitored (S5), and when the failure trigger is generated, the contents of the work buffer before the trigger are transferred as the failure record ( Storing) (S6).

As shown in FIG. 11, this work buffer stores digital information as sampling data at each sampling interval. Since the failure record is created for each monitor device 1 unit, it is possible to check the status of the SIV device 2, the VVVF device 3, etc. before and after the occurrence of a failure in one vehicle, but a vehicle control device for another vehicle. It is not possible to confirm what the condition was like.

Normally, the SIV device 2 and the VVVF device 3 are not mounted on the same vehicle, so even if a failure occurs in the VVVF device 3 and a failure record is created, at that time, the SIV device
Unless the device 2 has a simultaneous failure, it does not remain in the failure record and there is no means to confirm the state at that time.

[0009]

In the conventional monitoring system described above, the failure of one vehicle in the same train affects other vehicles, often leading to a serious accident. There is no way to know the status of other vehicles.

Therefore, the present invention provides a train monitoring system in which the cause of a failure can be easily determined, and even if the failure recording capacity is increased, the failure record search can be easily performed and the failure location can be found early. The purpose is to

[0018]

BEST MODE FOR CARRYING OUT THE INVENTION Embodiments of the present invention will be described with reference to the drawings. <First Embodiment> The present invention requires a highly accurate time adjustment function.
Will be described with reference to the block diagram of FIG. The difference from the conventional example of FIG. 9 is that a time adjustment SW (switch) 7 and a reader 9 are newly provided.

SW7 is pressed to adjust the time after the power is turned on. When SW7 is pressed, the monitor device 1
All of (1), 1 (2), ..., 1 (12) are configured to include the SW pressed state.

When the SW pressed state is detected, the lead car monitor device 1 (1), which is the master station for mutual transmission between the monitor devices 1 (1) to 1 (12), transmits the SW press time to all cars. Other monitor devices 1 (2) to 1 that have received this time
(12) calculates the difference between the SW pressing time detected by itself and the reception time, and corrects its own clock.

If the time setting SW 7 is not provided, the start SW of the monitor and the loading state of the mass control can be used as substitutes for each vehicle. However, in the present invention, the time is set accurately. It is supposed to be done.

The operation of the present invention will be described with reference to the recording / storing sequence of FIG. 2. The difference from the conventional example of FIG. 10 is that steps S7 and S8 are added. That is, each of the monitor devices 1 (1) to 1 (12)
It is detected whether or not it is a failure occurrence trigger of the vehicle control device, and the state of each vehicle control device before and after the trigger is stored as a record. If there is a failure trigger, send the time (S7),
When it is determined that the failure trigger has not occurred, it is determined whether the failure time is received (S8), and when the failure time is received, the record before the trigger is transferred (stored) (S6). , The state of each vehicle control device before and after the trigger is stored as a record.

The monitor device 1 (1) always stores the state of the vehicle control device in the work buffer, and also stores the sampling time thereof. At the same time, a trigger for creating a failure record is monitored (S5), and if a failure trigger occurs, the work buffer contents are stored as a failure record, and the trigger occurrence time is monitored by another monitor device 1 (2) ...
1 (12). Monitor devices 1 (2) to 1 (1
In 2), not only the trigger occurrence is detected, but also the failure record is stored in the work buffer when this time is received.

In the work buffer, as shown in FIG.
The storage time is included in addition to the digital information stored at each sampling interval. Since the transmission time and the processing delay occur at the reception time when the failure trigger is generated, the capacity of the work buffer that stores the state of the vehicle control device needs to be a sufficient consideration of the delay time.

The above will be further described with reference to FIG. As a failure record, the system stores data for 1 second before and after the detection of trigger occurrence. Here, for example, the VVVF device 3 is connected to the monitor device 1 (1).
Here, when a failure occurs in the VVVF device 3, the monitor device 1 (1) detects a trigger, stores the digital and analog information in the work buffer before the trigger as a failure record, and also sets the trigger time to another value. Monitor device 1
Transmit to (2). The monitor device 1 (2) compares this reception time with the time of the record data in the work buffer, and stores a record of 1 second before and after the point of coincidence as a trigger point. Thus, when a failure occurs in another monitor device 1 (1), the monitor device 1 (2) can also create a failure record.

As a result, it becomes easy to investigate the cause of failure,
Further, even if the failure recording capacity increases, the failure record search can be easily performed, and the failure location can be found early. <Second Embodiment> As shown in the block diagram of FIG.
Vehicle control device, SIV device 2, VVVF device 3, ATS
-The failure signal of the P device 4 is monitored by the monitor device 1 (1) of all vehicles.
Input 1 (12). Monitor devices 1 (1) to 1 (1
In 2), the occurrence of the trigger is detected, and the states before and after the occurrence of the trigger are recorded and stored. In this record, a record when the vehicle control device has not failed is also created. These records do not require time adjustment, and the leading vehicle monitor device 1 (1) stores the detection time of the trigger occurrence,
If these records are collected through a transmission line, a simultaneous failure record of another vehicle due to the occurrence of one failure can be created.

In this case, by causing the monitor devices 1 (1) to 1 (12) to monitor the simultaneous failure occurrence time, each monitor device 1 can correct the time due to the detection time difference at the time of record collection. .

Similar to the time adjustment method described above, the leading vehicle monitor device 1 (1) determines the failure detection time to the entire monitor device 1 (1).
(1) to 1 (12). Each monitor device 1 (1)
1 to 12 (12) compares the detection time of the failure signal 6 with the reception time, and corrects the deviation with its own clock.

These trouble records can be displayed by editing the trouble record menu on the monitor display 8. Since the status of all vehicle control equipment is monitored, the failure record becomes enormous. Therefore, the failure record is read out by connecting the reader 9 when the operation of the vehicle ends, and is edited on the reader 9 to display detailed information.

The reader 9 performs the operation as shown in the reader search operation sequence of FIG. 6, and displays the failure record menu based on the trigger condition for failure occurrence. This content can be displayed by selecting it from the menu.
Display of all records and search display are possible (S10,
S11, S12). In the search display, by selecting the car, selecting the vehicle control device, and selecting the specific signal of the vehicle control device, the record of the portion matching the selection is displayed together with the occurrence time.
As the search condition, the state of the device related to the failure occurrence part is registered in advance. The registration condition is recorded and compared with the read failure record, it is determined whether or not there is one that matches the comparison (S10), and the menus are displayed in order of date. Of the items selected from the menu, items that match the previously registered recording data type are selected and displayed. Usually, as for a vehicle failure, the related failure is often known in advance, and such a display facilitates the estimation of the cause.

Since a record of a failure that occurs in one vehicle is created by all monitor devices, a plurality of failures often occur in succession. For example, assume that a failure occurs with the A failure signal as shown in FIG. 7 and a B failure signal occurs 0.3 seconds after that. It means that the B failure signal is generated while the failure record triggered by the A failure signal is being created. In this case, the failure record with the A failure signal is 1.3 seconds before the failure (1 second before the failure, 0.3 seconds after the failure), and the failure record with the B failure signal is created by the normal operation like b. To do.

When the B failure signal is detected, a B failure signal generation trigger and a continuous flag are set at the end of the failure record of the A failure signal. When the A failure signal is displayed on the reader 9, the normal display operation is performed until the continuous flag is detected. At the time when the continuous flag is detected, the same failure record as the time at that time is searched and the remaining record data is 0. ．Displays 7 seconds and records 1 second before and after fault recording.

<Modification> In the configuration in which each vehicle control device and each monitor device are connected by a transmission line as described above, a function of receiving a failure occurrence time in each vehicle control device,
By providing a function of inputting a failure signal, a recording function similar to that of a monitor device can be realized.

[0034]

According to the present invention, when a failure occurs in one vehicle, the operation of other equipment at that time can be confirmed, so that the cause of the failure can be easily identified, and even if the failure recording capacity increases, It is possible to provide a train monitoring system that enables easy search of failure records and facilitates early detection of failure points.
