- the message information transmitted from the on-board device due to a memory abnormality in the on-board device (including memory abnormality on both the transmitting side and the receiving side).
- a problem (failure) that causes the contents of the message to be the same every time but also a problem (failure) that can only output a telegram of the same signal due to factors other than memory errors (for example, a failure in the transmission system such as the modulator) ).
- FIG. 2 is a functional block diagram showing the internal configuration of the vehicle upper side communication device 14.
- the vehicle side communication device 14 includes a communication control unit 20 that generates message information 26 that is information included in the check message 18, and a message control unit that converts the message information 26 into, for example, a binary signal and outputs the binary signal.
- FSK modulation unit 22 that outputs a modulated signal obtained by FSK modulation of a signal from the telegram control unit (transmission side) 21, for example, and an FSK signal transmitted from the FSK modulation unit 22 (
- the check telegram 18) is received via the vehicle upper 16 connected to the vehicle upper side communication device 14, and the FSK demodulator 24 that demodulates the received FSK signal, and the demodulated signal from the FSK demodulator 24

- the communication control unit 20 determines the check message 18 to be transmitted, and confirms whether or not the received check message 18 is abnormal, that is, the soundness of the message (control message) to be received from the ground device. Confirmation process is performed.
- FIG. 3 is a flowchart showing the flow of the self-checking process in the vehicle upper side communication device 14.
- step S101 the self-checking process in the vehicle upper side communication device 14 is started when the power is turned on (step S101).
- the vehicle upper side communication device 14 determines whether or not a predetermined time has elapsed since the last transmission of the verification message (step S102). If the predetermined time has not elapsed (step S102, No), the determination process of step S102 is repeated. If the predetermined time has elapsed (step S102, Yes), whether the vehicle upper element 16 is coupled to the ground element 30 or not. Is determined (step S103). Here, if the vehicle upper member 16 is coupled to the ground child 30 (step S103, Yes), the processes of steps S102 and S103 are repeated.
- Step S104 a verification message that simulates the control message is generated (Step S104), and the generated verification message is transmitted to the vehicle element 16 as shown in FIG. (Step S105).
- the vehicle upper side communication device 14 receives the verification message through a feedback circuit configured via the vehicle upper element 16, and performs an abnormality determination on the received verification message (step S106).
- an abnormality counter can be used as a means for performing this abnormality determination process. If there is no abnormality in the check message (step S107, Yes), the count value of the abnormality counter is reset (step S108), and the process proceeds to step S102. On the other hand, if there is an abnormality in the verification message (No at Step S107), the count value of the abnormality counter is incremented (Step S109), and it is further determined whether the count value of the abnormality counter is less than a predetermined value (Step S110).
- Step S110, Yes If the count value of the abnormality counter is less than the predetermined value (step S110, Yes), the process proceeds to step S102 in the same manner as when there is no abnormality in the check message, and if the count value of the abnormality counter is equal to or greater than the predetermined value. (Step S110, No), the failure of the on-board device is detected, and this flow is finished (Step S111). That is, in the processing of steps S107 to S111, when the abnormality of the check message is continuously determined for a predetermined value (predetermined number of times), the on-board device is determined to be a failure. In this sense, the predetermined value may be an integer of 2 or more.
- step S104 for example, processing such as incrementing the content of the verification message is performed.
- processing such as incrementing the content of the verification message is performed.
- a check message is generated with different contents each time it is transmitted.
- the check message is a message that simulates the control message, basically, the check message is not output when the vehicle upper 16 and the ground 30 are connected. However, it is conceivable that the vehicle upper element 16 and the ground element 30 are immediately connected to each other immediately after it is determined in step S103 that the vehicle upper element 16 and the ground element 30 are not combined.
- the connection determination process between the vehicle upper member 16 and the ground child 30 is performed and the vehicle upper member 16 and the ground child 30 are not combined.
- the on-board device is normal, for example, even if it is determined to be abnormal in the first determination process in an interference state, the second process is It can be correctly determined as normal.
- the transmission interval of the verification telegram when the predetermined time, that is, when the vehicle upper member 16 and the ground child 30 are not connected is, for example, when the vehicle upper member 16 and the ground child 30 are connected during normal driving. It can be any time that exceeds the time that it is.
- the FSK modulation unit 22 and the FSK demodulation unit 24 are disclosed as the modulation unit and the demodulation unit in the in-vehicle communication device 14, but other modulation / demodulation methods are used. It doesn't matter.
- the verification message is a message that simulates the control message.
- the message may not necessarily be a message.
- the important point is that the contents of the verification message need only be updated in some way each time the verification message is generated. For example, if the content changes even with one bit, it is possible to detect a fixing failure. .
- the on-vehicle transponder device and its soundness confirmation method according to the present embodiment, only the device on the vehicle upper side is used without using the ground side equipment, that is, the ground side communication device and the ground element. Can confirm the soundness of the ground side communication device.
- the vehicle-side communication device is turned on, that is, the train is turned on. For example, it is possible to determine the sticking failure at any time regardless of the train stoppage, and it is possible to quickly and accurately determine the sticking failure. Therefore, a failure can be found before traveling by setting the above-described test contents as, for example, daily daily inspection items for trains.
- the signal transmission unit (the telegram control unit (transmission side) and the FSK modulation unit) in the on-vehicle device and the signal reception in the on-vehicle device. Since the feedback circuit is configured through the vehicle upper part with the unit (the message control unit (reception side) and the FSK demodulating unit), not only the fixing failure but also the communication function (for example, the filter circuit) in the vehicle device It also becomes possible to confirm the soundness.
- the on-vehicle transponder device according to the present invention is useful as an invention that enables quick and accurate determination of a fixing failure.
