Testing apparatus and testing method for an electronic interlocking system

Abstract

This electronic interlocking system comprises an interlocking logic part 6 creating control commands of a field apparatus 12, a field control terminal 7 outputting controls to the field apparatus 12, and simulation means 10 simulating a function of the railway signal field apparatus 12 at the time of test. The system is equipped with a test system interlocking logic part 3 connected with the field control terminal 7 and having a follow mode for performing control not to avoid the action of the interlocking logic part 6. The interlocking logic part 6 and the test system interlocking logic part 3 output independent control commands relative to the railway signal field apparatus 12 along with output existence / absence information to the field control terminal 7. The field control terminal 7 outputs control commands of the interlocking logic part 6 when the interlocking logic part 6 outputs the control commands outputted to the field apparatus 12 and the test system interlocking logic part 3 is in a follow mode or does not output.

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. [0003] In additio...

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.
