An embodiment of the present invention will be described below with reference to one drawing. 10. FIG. 1 shows the configuration of the present invention. 1 is a diagram showing each vehicle. Each of these vehicles 1 includes a speed detector 10 for detecting the running speed of the vehicle and various devices 1 mounted on the vehicle.
A processing device 4 is installed to monitor and process the status and failure of the device. The processing device 4 includes a calculation section 5, an input section 7 that takes in information from the speed detector 10 and each device 1, a transmission section 8 that performs transmission with processing devices installed in other vehicles, a program module, a failure record, etc. , a processing device 4 in a specific vehicle such as a leading vehicle with a driver's cab or a vehicle with a conductor, and an output section 9 that outputs stored data and the like. Further, a display device 2 for displaying data outputted from the output section 9, and a printing device 3 for printing the output contents such as data to obtain a note copy are installed in the specific vehicle, and the driver and conductor can see the driving state. It is now possible to visually check information such as failure records and other information.

The operation of this device having such a configuration will be explained.

The monitoring device configured as described above monitors the status of the equipment 11 mounted on each vehicle in each processing unit 4, and transmits status changes to the processing unit 4 of the vehicle operated by the driver or conductor via the transmission line 12. do.

These pieces of information are received by each transmission unit 8, and this received information is sent to the specific processing device 4 mentioned above.

Then, the input information including the equipment state information of the own vehicle taken in by the input section 2 of the specific processing device 4#'i is subjected to calculation and editing processing in the calculation section 5, and outputted to the output section 9. The processed information is sent to the display device 2 by this output section 9.
The conversion and output processing for displaying or printing on the display device 2 or printing device 3 is performed, and the output is output to the display device 2 or printing device 3 for display or printing.
It will be printed.

The status of the equipment can be grasped by checking the output of the printing device 3.

Further, when a device failure occurs, each processing device 4 records device failure information and transmits it via transmission. and,
This transmitted equipment failure information is received by the specific processing device 4, taken in by the transmission section 8, edited by the calculation section 5, and stored in the storage section 6. This is the effect of a normal monitor device.

In addition to the functions of a normal monitor device, this device also has the following functions:
It has a function to collect vehicle performance measurement data during normal driving.

That is, within the specific processing device 4, speed information from the speed detector JO is input to the calculation section 5 via the input section 7, and the calculation section 5 performs speed calculation and distance calculation. The distance of the first train and the start time when the power is turned on are set from the setting device in each device. Based on this initial setting, the distance is calculated by adding the distance in the case of the lower position and subtracting the distance in the case of the upper position. In addition, the time is determined by a clock device (not shown), and the specific processing device 4 to which the time is set is transmitted via the transmission unit 8. The processing device 4 of the other vehicle, which has been notified of the time, takes into account the time delay in transmission,
Set up your own clock device. Each processing device 4 collects device status information at the same cycle.

Furthermore, the storage unit 6 in the specific processing device 4 has one
During deceleration, the processing device 4 stores the recordable point information and speed stage information to collect information during acceleration and deceleration, and when decelerating, the processing device 4 executes the ST and DE STJ processes shown in FIG. As shown, entering a recordable point indicated by reference numeral 32 is detected by comparing the distance calculation value with the recordable point information in the storage section. This recordable point information takes into account conditions such as slipping and skidding, and records the distance until the vehicle enters the first speed stage advancement point indicated by reference numeral 25 in FIG. The specific processing device 4 then enters step STJ and executes this to detect a recordable point.
The speed is monitored until the speed is advanced to the first speed gear, and at the time the speed is advanced, the ST/DE STJ shown in FIG.

Next, the specific processing device 4 executes step fSTj in FIG. 3, and records information such as time and speed, and device status information. In addition, other processing devices also record time and device status information an appropriate amount of time past the current time, taking into account time delays. The information to be recorded may be all of the captured information, or the primary specific processing device 4 that may select and record information is 13'l'4. in FIG. In the execution of STj, the stopping point is detected based on the speed O.

Then, when the stopping point is detected, Step 6 executes fB T 6 and sends it to the transmission unit 8 and transmission path 12 in FIG. 1 to other processing devices.
We will notify you of this and request that the recording be terminated. Then, they stop recording themselves.

Other processing devices that have received this notification detect the notification and stop recording. Thereafter, the specific processing device 4
T7 is executed, and records are collected to the specific processing device 4 by transmission from the other processing device 4 side.

The specific processing device 4 stores the collected records as they are, or edits the deceleration information, speed information, and equipment status information according to the speed stage as shown by reference numerals 26 and 27 in FIG. Remember.

The specific processing device 4 then executes step ST8, requests the input unit 7 to output information, receives information from the device 11, stores it in the storage unit 6, and also outputs information in response to a separate request. The display device ff12 and the printing device 3 are caused to display and print information via the output section 9.

In this way, a record of deceleration performance can be kept.

When accelerating, move from the stop point indicated by mark 28 on the FA2 diagram to mark 3.
Acceleration performance can be recorded by recording acceleration information or information similar to that described above up to the coasting point indicated by 1 or a specially set recording end point.

In the manner described above, it is possible to record vehicle performance during acceleration and deceleration during normal operation.

If the vehicle performance described above is not sufficient to be measured and recorded, it is determined whether or not to record it by executing step 5T49. That is, if the vehicle has advanced to the first speed gear at the recordable point, the information may be discarded. but,
If you look at it not as a vehicle performance record, but as a separate driving record, you can also keep it.

In FIG. 2, 21 is the speed curve, 22 is the first speed stage, 23 is the second speed stage, 24 is the nth speed stage, and 25 is the first speed stage.
Speed gear advance point, 26 is a second speed gear advance point, 27 is a third speed gear advance point, 28 is a stop point, 29 is a second speed gear advance point, 30 is a first speed gear advance point, 32 is a recordable point.

Moreover, by setting similar conditions in tests performed during vehicle inspection, records can be obtained, which is also effective for maintenance.

It should be noted that the present invention is not limited to the embodiments described above and shown in the drawings, but can be implemented with appropriate modifications within the scope of the gist thereof.For example, the above clock device may be implemented in a specific processing device. It may also be built-in.
