Description

Universal processing method for inspection logic of starting end and terminal of route

Technical Field

The invention relates to the field of rail transit signals, in particular to a processing method of inspection logic of an initial end and a terminal of an approach.

Background

In the field of rail transit signals, an access train refers to a path that travels from one location to another within a station. According to the properties of the train, the routes can be divided into two categories of train routes and shunting routes; the system can also handle a guide route without checking the rail circuit vacancy, and is suitable for train operation under the condition of rail circuit failure.

After the operator presses the start and end buttons of the approach, the executive group network records the approach range of the train approach or the shunting approach by using a KJ (start relay) and a ZJ (terminal relay), and performs locking condition check on the basis of the approach range, so as to prevent rear-end collision or head-on collision safety accidents caused by establishment of an adversary approach.

At present, the processing mode of the route starting terminal basically adopts the design principle of the traditional relay: setting LKJ (train start relay) and KJ (shunting start relay) to distinguish the route property for the signal machine which can be used as the starting end of the train route and the starting end of the shunting route; and a terminal relay ZJ is arranged on the signal machine which can be used as the train route terminal and the shunting route terminal, wherein the closing of the front node of the ZJ indicates that the signal machine is used as the shunting route terminal at the moment, and the closing of the rear node of the ZJ indicates that the signal machine is used as the train route terminal at the moment. However, this method has the following drawbacks:

one is that the train may be switched into a rear-end collision due to wrong handling of the guidance route. After the shunting route is established, the first section of the route is unlocked along with the running of the train, according to the characteristics of a YXJ (guide signal relay) circuit, an excitation branch circuit checks that ZJ is in a falling state, if ZJ falls due to reasons at the moment, a guide signal is mistakenly opened and cannot be guided to a safety side, and adversary routes which are overlapped in the same direction are simultaneously established, so that the accident of rear-end collision and shunting of the train is caused.

And secondly, the head-on enemy approach of the two-way shunting station road cannot be controlled and is not allowed. In the traditional processing mode, a turnout-free section does not allow bidirectional shunting, and a circuit detects the shunting signal ZJ at the other end of the turnout-free section in a falling state by depending on an excitation branch of a terminal signal ZJ to carry out card control which cannot be handled by enemy approach. However, when the signal machine at the other end can be used as a train route terminal (such as a station yard with a short station track), according to the characteristics of the ZJ circuit, the train route ZJ established at the other end of the turnout-free section is still in a falling state, and the establishment of the head-on enemy route at the other end cannot be proved by checking the falling of the signal machine ZJ at the other end.

in the case shown in fig. 2, there may be two routes of guidance: XD-SI and SI-XD, but no instruction of guiding the code bit of the route at this time, therefore judge that XD and SI V _ SD _ yd condition is not satisfied, guide the starting end condition of the route is not satisfied.

S26, determining whether the shunting route start end condition is satisfied, and if the shunting route that is likely to be satisfied is D35-SI in the case shown in fig. 2, step S26 specifically includes the following determination flow:

s261, D35 with the attribute capable of being used as the starting end of the shunting route receives the position command of the shunting starting end code, and route selection is consistent, so that the secondary sub-condition v1_ SD _ dc is satisfied;

s262, checking that all turnouts and protection turnouts in the approach are not in a blocking state, so that a secondary sub-condition v2_ SD _ dc is established;

s263, checking that all sections in the access path, namely 57-59DG, are in an unlocked state, so that a secondary sub-condition v3_ SD _ dc is established;

in step S264, the shunting terminal condition of the route, that is, the v _ ZD _ dc condition of SI is confirmed to be not established in step S23, and therefore the v _ SD _ dc condition of D35 is not established and the shunting start end condition of the route is not established.

S3, generating a route all-time end logic;

and judging whether the establishment conditions of the initial end and the terminal end of the route are formed or not according to the processing result of each module in the step S2. Specifically, it is determined whether or not there is an entry in which the start condition and the end condition are satisfied at the same time, and if so, it is determined whether or not a locking condition corresponding to the entry is satisfied, and if a corresponding locking condition is also satisfied, the entry is locked.

If the starting end condition and the terminal end condition are satisfied simultaneously, whether the corresponding train route locking condition, the guiding route locking condition or the shunting route locking condition is satisfied is judged, if the locking condition corresponding to the route satisfied by the starting end condition and the terminal end condition is also satisfied, the route is locked, and the starting end and the terminal end satisfaction information of the route is output.

If there is no route in which the start and end conditions are satisfied simultaneously, or if the start and end conditions are satisfied and the corresponding locking conditions are not satisfied, the route of the train cannot be made.

In the embodiment shown in fig. 2, according to the determination process of S2, if only the starting end condition and the ending end condition of the train route XD-SI are satisfied at the same time, in S3, it is determined whether the locking condition of the train route XD-SI is satisfied, and if the locking condition is satisfied in this embodiment, the starting end of the train route XD and the ending end of the train route XD-SI are output as SI.
