2. Description of the Related Art FIG. 3 is, for example, No. 310 of 21st (November, 1984) 21st domestic system paper collection on cybernetics in railways issued by Japan Railway Cybernetics Council.
It is a symposium block diagram of the conventional train monitor device which displays and records the domestic information of each equipment mounted in the train shown on the page. In the figure, reference numeral 1 is the endmost vehicle at one end of the train. This endmost vehicle 1 monitors a target device 4 to be a failure monitoring target, the operation of the target device 4, and records the failure information when the failure information is detected. A monitor (hereinafter referred to as a Tc monitor) 5 and a display control device 6 for displaying recorded information of the Tc monitor 5 are provided.

Reference numeral 2 is the endmost vehicle at the other end of the train, and this endmost vehicle 2 has the target equipment 4, the Tc monitor 5 and the display control device 6 in the same manner as the endmost vehicle 1, and will be described in detail later. A central monitor 7 to be described is provided.

Numeral 3 denotes a plurality of vehicles, for example, four vehicles, which are provided with a target device 4 similarly to the end vehicles 1 and 2, and are also provided with a monitor (hereinafter referred to as M monitor) 8. Reference numeral 9 connects the Tc monitor 5, the central monitor 7, the M monitor 8 and the display controller 6, and displays monitor information on the display controller 6 and the central monitor 7.
It is a serial transmission line for transmission to.

Next, the operation of the conventional train monitor device configured as described above will be described. The conditions for inputting and recording operation information from the corresponding target device 4 on the Tc monitor 5 and the M monitor 8 of each vehicle, and the items of data to be input from the target device 4 accompanying this operation information are programmed beforehand. It is set.

Here, the operation information input condition means that when the target device 4 reaches a certain operation state, the Tc monitor 5,
Whether the M monitor 8 records operation information,
For example, when the target device 4 outputs a signal predicting the occurrence of a failure,
It means that the Tc monitor 5 and the M monitor 8 input operation information by using this signal as a trigger. Further, the data item refers to an item of operation data of the target device 4 which is necessary for elucidating the cause of failure.

The Tc monitor 5 or M monitor 8 for which the operation information input condition is set as described above monitors the operation of the corresponding target device 4, and the operation of the target device 4 reaches the above input condition. When is detected, the device operation information before and after the operation is recorded, and the failure occurrence is detected. Also, at this time, T
The c monitor 5 and the M monitor 8 also capture and record operation data of the target device 4 according to preset data items.

In this way, the recorded device operation information and operation data are transmitted to the display control device 6 in the endmost vehicles 1 and 2 through the serial transmission line 9 and displayed on the display section (not shown). .. Further, the information and data recorded on the Tc monitor 5 and the M monitor 8 are transferred to a portable recording medium such as a memory card, and input from the recording medium to a personal computer or the like outside the vehicle to be processed to cause a failure. The cause is clarified.

As a result, accurate information for predicting the occurrence of a failure in the target device 4 can be grasped, the cause of the failure can be investigated at an early stage, and detailed failure information can be provided to the train operator. Therefore, quick processing for a failure becomes possible.

[0010]

In the conventional train monitor device, the monitor is the operation information of the target device according to the operation information input condition and the data item preset on the program,
Further, in order to record the various data, in order to elucidate the cause of the failure, it is necessary to estimate various failure cases at the design stage of the target device and set the input condition and the data item as a program.

However, when the actual failure detection condition is insufficient, or when a failure that is not estimated occurs, erroneous information cannot be recorded or conversely necessary information cannot be recorded. However, there is a problem in that the information necessary for elucidating the cause of failure cannot be recorded.

Further, even if the information input condition and the data item set in the monitor are changed to solve the above problems, the information input condition and the data item are recorded in the ROM. Modified the program, ROM
Has to be exchanged, and there is a problem in that it is a labor-intensive and time-consuming task when the number of trains in a train is large.

The present invention has been made in order to solve such a problem, and the operation information input conditions and data items set in the monitor can be easily changed as appropriate.
An object of the present invention is to obtain a train monitor device capable of finely setting motion information input conditions and data items on a monitor.
