Technical Field
The invention relates to the field of rail traffic signal control, in particular to a turnout single locking method, turnout single locking equipment and turnout single locking medium based on line resource management.

In a conventional signaling system, after a switch is locked in a current position, an approach can be arranged through the same position of the switch. Meanwhile, the turnout under the access locking can also be locked singly, and the single locking/unlocking of the turnout and the access locking/unlocking are mutually independent. In a system based on resource management, when the same single lock function is executed, the sorting of the turnout area resources required by the running task path of the existing train may form conflict, and further, the operation deadlock is caused. Such as: the current position of the turnout is in positioning, the line resource positioned by the turnout is being solicited by the front train, the running task of another train (rear train) needs to pass through the inversion of the turnout, the inversion of the turnout and the area resource downstream of the turnout are reserved for the rear train and counted into the second position in the ordered list, once the turnout is in positioning, if the relevant line resource of other rear trains (rear trains needing to pass through the current turnout inversion of the turnout) is reserved and counted into the ordered list without intervention, the front train drives away from the line resource positioned by the turnout and completes the rear task, the turnout inversion line resource and the line resource reserved for the original rear train in the range of the running task of all the rear trains downstream of the turnout cannot be released, so that once the turnout is locked by the turnout, the other trains needing the turnout positioning line resource can not be allocated, and finally the multi-trains are in operation caused by the fact that other trains expect to release the line resource of the area of the current turnout are expected.

Step S103, the resource manager automatically activates a side defense area forbidden state of the other position of the turnout according to the current turnout position, and the step S104 is entered; if the current turnout position is not in the reverse (positioning) state, activating the turnout reverse (positioning) side defense area in the forbidden state; if the current turnout is in the non-representation state, all side defense areas of the turnout are automatically activated and deactivated until the turnout single lock state is canceled.
Step S104, judging whether the current train operation task passes through a side defense area in a forbidden state, if so, entering step S105, otherwise, entering step S106;
Step S105, assuming that the current position of the turnout is positioned, before the turnout performs single locking, if a train has received an operation task passing through a turnout inversion side defense area (the turnout inversion side defense area activated by the single locking), and a resource manager has created reservation or sorting for line resources related to the task of the train passing through the inversion side defense area of the turnout, and when the guaranteed parking point projection of the current train has no intersection with the area range from the turnout side defense area to the task end point and the current position of the turnout is inconsistent with the train task, once the turnout is activated into a single locking state (the single locking is positioned at the current position), the current turnout inversion side defense area automatically activates an inhibition state, and automatically cancels reservation of all line resources from the next section area of a guaranteed parking point to the task end point of the current train and deletes the current train ID in each area sorting list of the line resources;
Step S106, judging whether the current turnout position is consistent with the running direction of the train, if the current turnout position is in the reverse (positioning) position, no influence is caused when the running direction of the train is the turnout reverse (positioning), otherwise, entering step S107;
Step S107, assuming that the current turnout is positioned, after the turnout performs the single lock, if an operation task passing through the turnout inversion side defense area (the side defense area activated by the single lock) is applied for the trains, all the line resources on the upstream and downstream related to the turnout inversion side defense area are refused to be reserved, ordered and allocated for the trains due to the activation of the forbidden state of the key turnout inversion side defense area until the single lock of the turnout is released and the forbidden state of the area is released.
The side defense area prohibition state is only suitable for prohibiting all operation tasks passing through the side defense area (the side defense area activated by the single lock) at the other position of the current turnout, and does not affect all operation tasks, reservation, sequencing or allocation of the current position of the current turnout, and also does not affect the train running in the area.
The embodiment also relates to a turnout unlocking method based on line resource management.
As shown in fig. 2, the switch unlocking single lock activity diagram based on line resource management specifically includes:
s201, a dispatcher confirms that a switch unlocking command is issued to a resource manager for the tasks of all trains passing through the switch requiring the single lock according to the operation condition and the switch state.
S202, the resource manager executes the operation of unlocking the turnout, and the turnout automatically unlocks the single lock state.
S203, the resource manager simultaneously and automatically releases the forbidden state of the side defense area of the other position of the current turnout, if the current turnout is positioned, the forbidden state of the reversed side defense area of the turnout is automatically released, and otherwise, the forbidden state of the positioning side defense area of the turnout is automatically released.
