Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a method for simulating a site in an electronic interlocking device used in railways and the like.

[0002]

2. Description of the Related Art Even if an electronic interlocking device is installed in the field, the field equipment is connected to the existing equipment, and the train is in operation, so immediately the field equipment (signal, switch, track circuit) Cannot connect. Therefore, a predetermined interlocking test of the new device is performed on site, and then the switching is performed, and the test during that time is performed in a state of not being connected to the field device. If the device is operated in the unconnected state, it is not possible to receive a response from the field device. Therefore, a field simulation device must be separately connected. For example, in the case of a traffic light, a resistor equivalent to an actual light bulb is required. The larger the size of a station, the larger the size of the station, and the larger the size of the station, the larger the size of the station.

[0003]

As described above, the conventional electronic interlocking device requires a device for simulating a site at the time of on-site testing, and has various problems as described below. (1) The site simulator must be prepared separately from the electronic interlocking device itself. Moreover, the site simulator is M
It must be prepared for AX field equipment. (2) In the case of a traffic light bulb, the resistance becomes enormous and the heat generation is large. In addition, wiring work matching the pin assignment will occur at the station. (3) It is difficult to switch between the on-site simulator and the on-site equipment each time the on-site contrast test is performed. (4) When the electronic terminals are distributed, a site simulator is required for each electronic terminal, and the short circuit / open operation of the track circuit is distributed, which is difficult to do.

Therefore, the present invention solves the above-mentioned problems of the prior art and enables a test of an electronic interlocking device to be performed without a site simulator, thereby facilitating on-site testing and improving efficiency. The purpose is to provide.

[0005]

In order to achieve the above object, the invention of claim 1 is the electronic interlocking device as described above, wherein the electronic terminal has a real machine mode and a simulation mode, When an instruction is given, it becomes a simulation mode, and during the simulation mode, regardless of whether it is connected to the field equipment, it responds to the control from the electronic interlocking main body mode as if it is connected to the field equipment It is characterized in that the same response as the above is sent to the electronic interlocking body. According to a second aspect of the present invention, in the first aspect, when the electronic terminal receives a simulation instruction from the electronic interlocking main body, the field device is stopped and locked as needed, and a simulated answer is issued to the electronic interlocking main body. The feature is that it becomes the simulation mode later.

[0006]

According to the on-site simulation method as described above, the electronic terminal is set to the simulation mode so that it is connected to the on-site device even if it is not connected to the on-site device for control from the electronic interlocking main body. The response can be returned to the electronic interlocking main body, and it becomes possible to perform a field test without a field simulator.
