A method for initializing and verifying the existing control state after restarting the interlocking equipment

Abstract

The present invention relates to a method for initializing and verifying the existing control state after the interlocking device is restarted, comprising: after the CI device restarts and the TSR initialization fails, each field of any TSR command received by the CI device is checked for validity, and Verify the consistency of the number of devices and the device list. When the CI device receives a legal TSR verification command, it will record the TSR verification command information in the section; the CI device should verify the received TSR execution command; the CI device should Verify the received TSR execution cancel command. When the TSR execution cancellation command is completely consistent with the corresponding TSR verification cancellation command, the TSR cancellation command can be executed and the TSR information section will be canceled; the CI device accepts the legal TSR full-line verification cancellation command. , record the TSR full-line verification cancel command information in the section, and send it to the control display and maintenance machine. When the TSR full-line execution cancel command is exactly the same as the corresponding TSR full-line verification cancel command, execute the TSR full-line Cancel from section.

Description

technical field [0001] The invention relates to a train temporary speed limit technology, in particular to a method for initializing and verifying an existing control state after an interlocking device is restarted. Background technique [0002] After the CI (Computer Interlocking, computer interlocking) device restarts, it can read the effective speed limit information stored locally offline, use it as an initialization reference configuration, and send the locally stored speed limit status to ATS (Automatic Train Supervision, train automatic monitoring system), requesting to verify the validity of the storage rate limit. Operators can confirm the speed limit information of the offline storage section (the interconnection requirement is "temporary speed limit section") through ATS according to the actual speed limit requirements in the line area. If it is confirmed to be valid, ATS will feed back the effective speed limit command to CI; if it is confirmed to be invalid, th...

Problems solved by technology

[0009] Due to the restart of CI, the temporary speed limit status of the section is in a safe state (the minimum speed limit of the whole line). After manually canceling the speed limit of the whole line, the location of some sections will be in an unsafe state, although this section will be processed in time Reasonable speed limit at the location, but this process reflects unsafe operation, and affects driving efficiency and driving safety at the same time
