Background

In the operation process of a traditional signal system, if the number of the points of the traditional signal system is larger than the power supply capacity of the points, the traditional signal system can cause power supply faults, and then operation interruption is caused. In order to prevent the fault, the technical requirement of driving the turnout by staggering the peak is provided. In the current signal system, on one hand, the number of the driven turnouts does not reach the maximum available capacity of a turnout power supply, and on the other hand, the turnouts are started based on a predefined peak shifting sequence, so that the action time of the whole turnout is prolonged, and the rail transit operation capacity is sacrificed; on the other hand, the predefined switch peak shifting action sequence relationship is only defined between a plurality of switches in a route or between a plurality of switch machines of a group of switches, for the switches which do not have the association relationship with the route, the switch peak shifting action sequence relationship is not defined, the randomness of the switches is operated due to the handling of parallel routes or manual maintenance, and the number of the switch machines which act at the same time may exceed the power supply capacity of the switch power module, thereby causing the switch power module to break down and further causing the operation to be interrupted.

Detailed Description

The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the drawings in the embodiments of the present invention, and it is obvious that the described embodiments are some, not all, embodiments of the present invention. All other embodiments, which can be obtained by a person skilled in the art without any inventive step based on the embodiments of the present invention, shall fall within the scope of protection of the present invention.

The invention provides a turnout action optimization control method based on turnout power supply energy constraint conditions, which takes a turnout power supply module as a resource, realizes efficient cooperative control between turnout input commands and turnout output control according to the number of turnout switch machines which can be supported to simultaneously act by the capacity of the turnout power supply module, meets the requirement that the power supply capacity of a foot turnout power supply module can be used when turnout is required to act, thereby improving the operation capacity of rail transit, and also can ensure that the risk of turnout power supply failure is reduced and the service life of equipment is prolonged by considering that the number of starting turnouts does not exceed the capacity of the turnout power supply module.

The method ensures the high-efficiency coordinated concurrent execution of the turnout input command and the turnout output control. In order to prevent the turnout control command from entering a deadlock state, the conditions of turnout control input and turnout control output are limited, and a turnout input command cache region and a turnout output control command cache region are established; the turnout power source resource is based on a first-come first-obtained and sequential execution principle; the turnout power supply resource only allows the turnout control command to be output under the limited condition of the rated capacity of the turnout power supply at any moment, and when the turnout control command is output and exceeds the rated capacity of the turnout power supply, the turnout control command is set to be in a waiting state, so that the turnout control command is executed within the turnout power supply capacity range, and the risk of turnout power supply failure is reduced.

Defining the power supply capacity of the turnout power supply module as a resource, namely defining the quantity of turnout power supply modules supporting simultaneous turning of turnout switch machines as M; the number of active switch commands received by the definition system is N.

Assuming that the actual number of switch input commands received is n, the number of switch power supplies supporting the operation of the switch machine is m.

After the signal system is started, the input command of the turnout enters a ready state (the number n of the received turnout commands is 0); the output control of the turnout enters a ready state (the number M of turnout power supplies supporting the operation of the switch machine is equal to M).

In the operation process of a signal system, the number of received turnout commands is N, if N is less than or equal to N, the N turnout input commands are sequenced based on the sequence number, and the N turnout commands are set to be in a turnout input command queue state, and in the state, the turnout input commands sequentially execute turnout output control based on respective serial numbers; and if N is larger than N, sequencing the number of the first N turnout commands based on the sequence number, and setting the subsequent N-N turnout commands as the 'blockage state of the turnout input command'.

If the input command of the turnout is currently in a queuing state and the number m of the turnout power supply supporting the switch machine to work is greater than 0, confirming that the turnout power supply resource is available, allocating the turnout input command with the sequence number of 1 and the turnout input command in the queuing state into a turnout control cache region until the turnout control cache region is full (the number m of the turnout power supply supporting the switch machine to work is 0), and exiting the circulation condition; when the execution of one switch command is completed, one switch power source resource (m +1, all switch command serial number n-1) is automatically released, and another switch input command in a queuing state is waited to be executed. The following steps are executed in a circulating way:

the number m-1 of switch power supplies supporting the operation of the switch machine;

executing the switch machine output control on the switch command with the current serial number 1 (the control delay time can be determined according to the whole performance of the system);

the number m +1 of switch power supplies supporting the operation of the switch machine;

-the number of input commands n-1 for a switch;

-the serial number of all switch input commands minus 1.

As shown in fig. 1: outputting a control flow chart for the turnout;

after the system is started, the output control of the turnout enters a ready state (the actual number M of turnout power supply control commands is equal to M);

under the condition that the number n of input commands of turnouts in a cache region is 0, the input commands of the turnouts enter a ready state, and under the condition that the number M of movable turnouts of a turnout power supply module is M, the output control of the turnouts enters the ready state;

the output control of the turnout is in a blocking state;

under the condition that the input command number n of the turnouts in the cache area is greater than 0 and the number m of the movable turnouts of the turnout power supply module is greater than 0, the number m of the movable turnouts of the turnout power supply module is m-1

Executing output control by using a turnout command with the serial number of 1;

the number m of movable turnouts of the turnout power supply module is equal to m + 1;

the number n of input commands of the switches in the cache area is equal to n-1;

subtracting 1 from the serial numbers of all input commands in the cache region;

under the condition that the number m of the movable turnouts of the turnout power supply module is equal to 0, the output control of the turnout is in a blocking state.

As shown in fig. 2, the switch input command control flow chart;

after the system is started, the input command of the turnout enters a ready state n which is 0;

if the turnout which receives a command to be executed from an access or manually operated turnout belongs to the power supply range of the turnout power supply module, storing the input command of the turnout into a cache region n which is n + 1;

if the number of the input commands of the turnout in the cache region is N > N, the input commands of the turnout enter a blocking state, otherwise, the serial number of the input commands of the turnout in the cache region is N.
