Embodiment 1

[0052] Please refer to the attached figure 1 , which is a schematic flowchart of a train protection logic verification method disclosed in Embodiment 1 of the present invention, the method specifically includes the following steps:

[0053] S101: Receive first operation data and second operation data, where both the first operation data and the second operation data are valid.

[0054] It should be noted that if the operation data includes the following content, it is called valid.

[0055] 1) Device status and click operation information

[0056] Status information of station equipment such as signal machine, section, turnout, screen door, etc.;

[0057] Click operation of signal machine, section, turnout, screen door and other station equipment.

[0058] 2) Click operation information of the function button

[0059] Function buttons include but are not limited to the following:

[0060] Turnout total positioning; turnout total reverse position; single lock; single relea...

Embodiment 2

[0069] Please refer to the attached figure 2 , which is a specific flow diagram of another train protection logic verification method disclosed in Embodiment 2 of the present application. The method specifically includes the following steps:

[0070] S201: Receive first operation data and second operation data, where both the first operation data and the second operation data are valid.

[0071] The receiving the first operation data and the second operation data specifically includes:

[0072] Receive the first operation data;

[0073] When the first operation data is valid, determine that the first operation data is the first operation data;

[0074] Start the preset timer and receive the second operation data;

[0075] When the second operation data is received and valid before the timer finishes timing, the second operation data is determined to be the second operation data.

[0076] S202: Combine the first operation data and the second operation data to generate a co...

example 1

[0087] Please refer to the attached image 3 , which is a schematic flow chart of a method for automatic verification of turnout locking logic disclosed in Example 1 of the present invention. The method specifically includes the following steps:

[0088] 301. Judging the locking mode of the switch.

[0089] It should be noted that this step involves the type of the received command message. If it is a turnout single lock command, it is to lock the turnout separately. The judging conditions for the single lock of the turnout and the locking of the turnout in the process of route selection are different, so the logic verification process is also different.

[0090] 302. Determine whether the switch is blocked.

[0091] If the turnout is blocked, feed back a warning message; otherwise, go to the next step.

[0092] 303. Determine whether the turnout section is occupied.

[0093] It should be noted that, when the judging result of step 301 is that the switch is individually l...

Abstract

The invention discloses a method and apparatus for verifying the protecting logic of a train. The method comprises receiving first operation data and second operation data, wherein both the first operation data and the second operation data are effective; generating a command to be triggered in dependence on the first operation data and the second operation data; acquiring the type of the command to be triggered if the command to be triggered is effective; and verifying the protecting logic of a train according to the type of the command to be triggered to obtain a verification result. By adopting the method and apparatus for verifying the protecting logic of the train, logical conditions of train protection can be implemented in modularization, the logical conditions can be implemented one by one according to the determination conditions in an actual process, and the implementation is distinct and clear.

Description

technical field [0001] The invention relates to the technical field of automatic control, and more specifically relates to a method and device for verifying train protection logic. Background technique [0002] With the development of my country's railway industry and urban rail transit industry, railway lines and urban rail lines tend to be more and more concentrated. Usually, the selection and arrangement of routes, cancellation of routes, single operation of equipment, Checking conditions, etc. is an essential operation. Taking into account the differences in personal qualities (such as operators who are not familiar with the train protection logic) and the limitations of the external environment (such as the time limit for troubleshooting and troubleshooting), all the above-mentioned train protection logic functions involved are realized manually. Inspection and verification are bound to fail to meet the requirements for system security in real-world conditions. The met...
