There is an interlocking device as a device for ensuring the performance.

FIG. 6 is a block diagram of a railway signal security system including an electronic interlocking device which has been widely used in recent years. An electronic interlocking device 1 for performing security control;
Field devices 6 such as a traffic light, a switch, and a track circuit are connected via an electronic terminal device 14 and a relay instrument box 7. The relay instrument box 7 is installed near the field device 6, and the electronic terminal device 14 is installed near the electronic interlocking device 1.
Usually, the electronic terminal device 14 is installed in the same equipment room as the electronic interlocking device 1.

[0004] For example, in order to control the traffic lights and the switches among the field devices 6, the electronic interlocking apparatus 1 first transmits the on-rail information of the train of the track circuit to the relay instrument box 7 and the electronic terminal 14. And operation data such as a train schedule from the centralized train control device which is a higher system of the electronic interlocking device 1. Then, based on the interlocking chart predetermined for each station, it is determined whether to turn on or off the traffic light or to change the point machine, and control output to the field device 6 via the electronic terminal device 14 and the relay device box 7. I do.

[0005]

However, in such a railway signal security system, when replacing an electronic interlocking device due to aging or the like, a confirmation test of a new electronic interlocking device is performed. The connection must be switched between the existing electronic interlocking device and the new electronic motor every time the confirmation test is performed.

[0006] Switching of the connection from the existing electronic interlocking device to the new electronic interlocking device is performed by disconnecting the existing electronic interlocking device and connecting the new electronic interlocking device while the train is not running. Will be For example, the connection between the existing relay device box 7 and the electronic terminal device 14 or the field device 6 is temporarily disconnected, a new electronic interlocking device is connected, and a confirmation test is performed. Then, after that, the connection is returned to the existing connection in preparation for running the train, and the signal security control is performed by the existing electronic interlocking device.

[0007] As described above, until the confirmation test of the new electronic interlocking device is completed, the connection switching operation must be repeatedly performed. In other words, the connection needs to be changed on the site every time the confirmation test is performed, which requires a great deal of labor. In addition, there is a possibility that a problem due to erroneous connection at the time of connection switching may occur. It is to be noted that a new electronic interlocking device is connected and operated after the confirmation test is finally completed.
