System and method for achieving control handover between vehicle depot and testing line

Abstract

The invention provides a system and method for achieving control handover between a vehicle depot and a testing line. The system comprises a vehicle depot in-situ work station A, a testing line in-situ work station B and an interlocking host C; the testing line in-situ work station B sends a testing request to the interlocking host C after a test train stops at the preset track section of the testing line to enable the interlocking host C to send testing request state information to the vehicle depot in-situ work station A; the vehicle depot in-situ work station A sends a non-route shunting route command to the interlocking host C according to the testing request state information to enable the interlocking host C to conduct non-route logic check and lock a switch on the testing line to make a straight line, open an enabling signal of a shunting signal on a non-route of the testing line and send testing permission information to the testing line in-situ work station B after passing the check; the testing line in-situ work station B deals with a train route for testing according to the testing permission information and sends testing canceling information after testing is ended to enable the interlocking host C to send testing end state information to the vehicle depot in-situ work station A; the vehicle depot in-situ work station A enables the non-route to be unlocked after delaying according to the testing end state information. The system is low in construction cost, high in integration level among devices and high in reliability and usability.

Description

technical field [0001] The invention relates to the technical field of rail transit, in particular to a system and method for realizing the handover of control rights between a vehicle depot and a test run line. Background technique [0002] The test line is set up to conduct static and dynamic tests on the test trains that have been put into formal operation, and to provide analysis of test results. The test line is generally set in the depot, and its track section, turnout and turnout protection signal are all under the jurisdiction of the depot. The test run operation can only be carried out by the control system of the test run line when it obtains the control right of the test run line. In this way, it is necessary to set up a strict control handover process between the interlocking system of the depot and the control system of the test line to ensure the safety of the test run on the test line. [0003] In order to ensure the safe and normal operation of trains and s...

Problems solved by technology

[0005] In the existing technology, a set of independent interlocking host equipment is installed in the jurisdiction of the depot, and a set of independent interlocking host equipment is also installed in the jurisdiction of the test line. At the same time, two sets of secondary train detection equipment (counted Axis or track circuit) for depot interlock and test line interlock to collect independently to detect the occupied idle state of the track section on the test line, which increases the investment and construction cost

Moreover, no matter whether the relay interface or the network digital interface is used for information interaction during the test run between the depot interlock and the test line interlock, when any link in the entire transmission channel of the two sets of interlock equipment fails, it will affect the depot and test run. The transfer of control rights between lines and normal test operation, this kind of equipment combination configuration reduces the integration between equipment, and also reduces the reliability and availability of equipment
