Electronic interlocking system and testing apparatus and testing method for the electronic interlocking system

Abstract

Equipped with the interlocking logic part (6) that generates the control command of the field machine (12), the field control terminal (7) that performs the control output to the field machine (12), and the field machine (12) that simulates the railway signal during the experiment. In the electronic interlocking system of the functional simulation mechanism (10), it is equipped with an experimental system interlocking logic part (3) connected to the field control terminal (7) and having a tracking mode that performs control without hindering the operation of the interlocking logic part (6). , the interlocking logic part (6) and the experimental system interlocking logic part (3) output to the field control terminal (7) the control command for the railway signal field machine (12) and the output information of the control command respectively to the field control terminal (7), and the field control terminal (7) For the control command output to the field machine (12), when the interlocking logic part (6) outputs and the experimental system interlocking logic part (3) is in the tracking mode or does not output, the output of the interlocking logic part (6) Control instruction. Therefore, when modifying the electronic interlock system that controls the railway signal field equipment, the connection switching of cables is omitted, and at the same time, the update operation of the electronic interlock system and railway signal equipment is simplified because part of the daytime experiment can be carried out.

Description

technical field [0001] The present invention relates to an electronic interlocking system for railway signal control, in particular to the electronic interlocking system and its experimental method when modifying already designed field machines and extending the functions of the electronic interlocking system. Background technique [0002] Hereinafter, the conventional method for modifying the function of the electronic chain system will be described. When establishing a new electronic interlocking system or comprehensively updating equipment, the newly established electronic interlocking system is generally set up adjacent to the original equipment, and the newly established electronic interlocking system is connected to the original on-site simulation mechanism to confirm the function Afterwards, when the original equipment is not working, the newly established electronic interlocking system is connected with the original equipment for experimentation.

AI Technical Summary

Problems solved by technology

In the case of inserting a switch, there is a problem that wiring work costs

In addition, in the case of changing the cables for each experiment, it is necessary to switch the connection from the simulation mechanism to the field machine before the experiment, and to switch the connection from the field machine back to the simulation mechanism after the experiment, and there is a replacement cost. The problem

In addition, since the connection confirmation is required after the connection is restored, there is a problem that the experiment time is shortened.
