A failure record file 11 for recording failure information is provided. Further, as features of this embodiment, a transmission failure detecting unit 16 for detecting a failure in the transmission system and a transmission failure recording file 17 for recording transmission failure information are further provided.

On the other hand, as shown in FIG. 2, a terminal device 3 which is a feature of this embodiment includes an input / output interface 12 serving as an interface for transmission information, and an information input unit 13 for inputting various information from the train component equipment 4. And an information editing processing unit 14 for editing vehicle information to be transmitted to the central device 1, and a failure detecting unit 15 for detecting a failure of the train component equipment 4 and providing the failure information to the information editing processing unit 14. Further, as a feature of this embodiment, a transmission failure detecting unit 18 for detecting a failure in the transmission system, information of a transmission failure detected by the transmission failure detecting unit 18 is recorded, and failure information detected by the failure detecting unit 15 is recorded. Transmission failure information recording file 19 for recording
It has.

Next, the operation of the monitoring system having the above configuration will be described.

On the side of the central unit 1, a request for information transmission is output to each of the terminal units 3 through the transmission line 2, and whether or not the response of each of the terminal units 3 to this request is normal is determined by input information from the input / output interface 8. , The transmission failure detector 16 constantly monitors the transmission failure. If an abnormality or a failure is detected, failure information such as an occurrence time, a recovery time, and a failure content is stored in the transmission failure record file 17 as a transmission failure record. Here, the content of the transmission failure is
There are response timeout errors, transmission protocol errors, transmission data errors, and the like.

In each of the terminal devices 3, the transmission failure detecting section 18 constantly monitors the transmission of a transmission request from the central device 1 and the transmission of a response to the central device 1 based on information from the input / output interface 12. Therefore, if an abnormality or a failure is detected, failure information such as an occurrence time, a recovery time, and details of the failure, and if the failure detection unit 15 detects a device failure during the occurrence of the transmission abnormality failure, the device failure information is also transmitted. It is stored in the failure information recording file 19. Here, the contents of the transmission failure include a request timeout error in addition to a response timeout error, a transmission protocol error, and a transmission data error.

FIG. 4 shows a flowchart of the information recording and transmission operations when a failure occurs in each of the terminal devices 3.
When a transmission failure occurs and is detected by the transmission failure detecting unit 18 (step S1), the failure information is created and recorded in the transmission failure information recording file 19 (steps S2 to S2).
4).

When the transmission failure is recovered (step S3), if the untransmitted failure record information is retained, the fact is notified to the central unit 1 and the transmission is performed in response to the transmission request from the central unit 1. The failure record and the equipment failure information during the occurrence of the failure are transmitted to the central device 1 (step S5). If the transmission does not end normally, it is assumed that a failure has occurred in the transmission system, and the transmission failure is recorded in the transmission failure information recording file 19 (step S6).
S4).

The central unit 1 records transmission failure information collected by itself and transmission failure information transmitted from each of the terminal devices 3 in the transmission failure record file 17.
If there is an output request from the display 5 or the ground reader 6, it is displayed on the display 5 and transmitted to the reader 6.

The present invention is not limited to the above-described embodiment. When a transmission failure occurs, the failure information is recorded in a file, and when the failure is recovered, the failure information is automatically transmitted from the terminal device to the central device. A function of transmitting can also be added.
