Problems solved by technology

[0004] At present, the common practice in the industry is to use the second confirmation operation. However, the second confirmation operation protects against the misoperation of the attendant, and to a certain extent, prevents the ATS from issuing control commands by mistake. The actual execution of the control commands is the equipment The problem of wrong display of the actual state has not been well resolved, thus laying a hidden danger to the behavior of the watchman who relies on the ATS display to make decisions

Embodiment Construction

[0021] According to the following Figure 1 to Figure 5 , the preferred embodiment of the present invention is described in detail.

[0022] The present invention provides a safety display method for controlling the execution state of a command, including a CRC (Cyclic Redundancy Check) between a train automatic monitoring system preset and a safety lower computer (trackside / vehicle / interlock) Check the transmission protocol, the automatic train monitoring system sends control commands to the safety lower computer through the preset transmission protocol, and receives the status feedback information returned by the safety lower computer through the preset transmission protocol, and the automatic train monitoring system uses CRC to convert VCP The security decoding technology converts the received status feedback information (naked data) of the security lower computer into VCP (Security Coding Processor) encoding, and then uses the VCP computing technology to convert the VCP en...

Abstract

A safety display method for control command execution state. The train automatic monitoring system uses the CRC to VCP safety decoding technology to convert the received state feedback information of the safety lower computer into VCP code, and the train automatic monitoring system uses the VCP calculation technology to encode the VCP code. Convert to display character ASCII code and display it on the screen. The invention shields the environmental interference and various software and hardware failures, ensures the actual execution state of the real display device, and greatly improves the security.

Description

technical field [0001] The invention relates to a subway signal control system, in particular to a safety display method for the execution state of a control command. Background technique [0002] As an important part of the subway signal control system, the automatic train supervision system (Automatic Train Supervision, hereinafter referred to as ATS) is interlocked with the microcomputer, trackside ATP (automatic train protection system, Automatic TrainProtection) equipment, vehicle-mounted ATP / ATO equipment and other signal equipment. Cooperate to realize centralized monitoring of signal equipment, and control the automatic operation of trains on the main line and depot / parking lot as planned. The process of ATS sending control commands to interlock, ATP and other equipment is as follows: the operator inputs the control request, selects the operation and the corresponding equipment, and the ATS feedbacks the equipment status after the execution is successful. If the exec...
