Each of the plurality of data collection devices 30 is assigned collection device identification information for uniquely identifying its own device.

FIG. 2 is a diagram showing an example of the configuration of the data collection device 30 of the state monitoring system 1 according to the embodiment of the present invention. As shown in FIG. 2, the data collection device 30 performs transmission of state information, a data acquisition unit 31 that acquires state information of the device 20, a data holding unit 32 that records state information acquired by the data acquisition unit 31. The device 20 includes the data communication unit 33, the device identification information reading unit 34 that reads the device identification information from the device identification information output device 21, the vehicle identification information reading unit 35 that reads the vehicle identification information from the vehicle identification information output device 11, and the data acquisition unit 31.

The collection device identification information may be recorded in advance in the data holding unit 32 instead of being output from the collection device identification information output unit 37 to the data holding unit 32. Note that the data holding unit 32 holds the state information of the device 20 for a predetermined period. The predetermined period is not particularly limited. For example, the status information of the device 20 for one day to several days may be held in the data holding unit 32. As a result, even when the status information cannot be transmitted due to a malfunction or the like of the data communication unit 33, the status of the devices 20 gathered for a predetermined period after the data communication unit 33 is restored or after the operation of the train 100 is completed.

Hereinafter, the flow of processing by the data collection device 30 of the state monitoring system 1 according to the embodiment of the present invention will be described with reference to the flowchart of FIG.

In the data collection device 30, for example, when a power source (not shown) is turned on, as shown in FIG. 3, the vehicle identification information reading unit 35 reads and acquires the vehicle identification information from the vehicle identification information output device 11, The data is output to the data holding unit 32 (S101). The device identification information reading unit 34 reads the device identification information from the device identification information output device 21 and outputs it to the data holding unit 32 (S102). In addition, the collection device identification information output unit 37 outputs the collection device identification information to the data holding unit 32 (S103). Note that the order of the processing of S101 to S103 is not particularly limited, can be changed, and may be performed simultaneously.

Next, the data acquisition unit 31 acquires the status information of the device 20 and outputs it to the data holding unit 32 (S104). Further, the time information acquisition unit 36 acquires time information indicating the date and time when the data acquisition unit 31 acquires the state information of the device 20, and outputs the time information to the data holding unit 32 (S105). The data holding unit 32 adds the vehicle identification information, the device identification information, the collection device identification information, and the processing information of S105 acquired by the processing of S101 to S103 to the status information of the device 20 acquired by the processing of S104. The acquired time information is recorded in association with each other (S106).

The data collection device 30 determines whether or not the status information of the device 20 for a predetermined number of times is recorded in the data holding unit 32 (S107). If the status information of the device 20 for the predetermined number of times is not recorded in the data holding unit 32 (S107: NO), the processes of S104 to S106 are repeated. When the state information of the device 20 for a predetermined number of times is recorded in the data holding unit 32 (S107: YES), the data communication unit 33 transmits the state information recorded in the data holding unit 32. Perform (S108). Note that the predetermined number of times is not particularly limited, and the data communication unit 33 may be set to perform transmission as long as state information for one time is acquired. For example, the data collection device 30 repeatedly performs the processing of S104 to S108 until the power is turned off. The data collection device 30 may repeatedly perform the processes of S101 to S103, but basically, while the power is on, the vehicle identification information, the device identification information, and the collection device identification information. Therefore, when the power is turned on, it is obtained only once and output to the data holding unit 32.

The state information recorded in the unit 32 is transmitted by wireless communication to the data communication unit 33 of the data collection device 30b, which is a transmission destination in the vehicle 10a, which is set in advance, as indicated by a dotted line in FIG. The data communication unit 33 of the data collection device 30b transmits the state information received from the data collection device 30a and the state information recorded in its own data holding unit 32 to the data communication unit 33 of the data collection device 30c by wireless communication. . As described above, the data communication unit 33 of each data collection device 30 sequentially performs transmission by wireless communication, so that one data collection device 30c of the plurality of data collection devices 30a to 30c provided in the head vehicle 10a is provided. The state information including the state information of the plurality of devices 20 mounted on the following vehicle 10b is collected.
