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, but 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 synchronous traction control system for a railway turnout by a single point switch/multiple point switches, which needs to realize the following parts: 1. and operating the turnout to rotate towards the positioning position/the reverse position according to the turnout operation command of the host equipment. For a scenario where only movable point switches are present and are controlled simultaneously by a plurality of switches, the system can control each switch to start in sequence and time-shared, with the start time interval being in a reasonable interval and being adjustable. For switches where there are point and point rails movable, it is achieved that the point and point rails are separately towed by different switch sets, and that the two switch sets may be configured to start off peak by peak or simultaneously. 2. If the turnout can not be started within a certain time, the operation of the turnout is stopped. In a scene where switches are simultaneously controlled by a plurality of switches, if all the switches cannot be started for a certain time, the rotation of all the switches is cut off. In the scene that the turnout is respectively pulled by the switch machine set for pulling the switch rail and the point rail, the cutting-off function needs to be respectively executed, and the mutual influence is avoided. 3. For a normal switch (no-block, no-stick), once the switch is activated, the switch should continue to be actuated until the desired position is reached, even if the control command to the switch is interrupted or stopped at that time. 4. During driving, the switch points can be controlled to move in the opposite direction. 5. If the switch is not able to rotate in place for a certain amount of time (which may be configured, typically 13/30 seconds), the drive to the switch is stopped after a timeout. 6. The switch can not be started again when the switch is stopped due to faults. 7. For multi-action turnouts, the action of the turnout which moves before (the turnout is in place) is required to be completed, and the action of the next-stage turnout is started. 8. The representation information of the turnout is collected and sent to the host equipment. Under the scene that the turnout is simultaneously controlled by a plurality of point switches, the turnout can be considered to be positioned/reversed only when all the point switches are positioned/reversed. For multiple-action switches, only two switches are in the positioning/reversing position, and the multiple-action switches are considered to be in the positioning/reversing position. And the system may provide sub-representative information for each switch machine. 9. During the turnout action time, non-representation information is provided to the host device.
To achieve the above requirements, the system of the present invention is composed of the following parts.
And the file configuration module is used for providing configuration parameters required by the control equipment. For the switch control function, the configuration data includes: (1) mapping relation of turnout and switch machine; (2) control parameters for each switch. The mapping relationship between switches and switches, for a scenario where a switch is controlled by a switch, should include: a) directly mapping the command of the host equipment to the turnout control module, b) directly mapping the state of the turnout control module to a representation replied to the host equipment; for a scene that a switch is jointly pulled by a plurality of switch machines, the method comprises the following steps: a) a mapping table of host device commands to switch machine commands, b) a mapping table of switch machine representations to switch representations; for the scene of the multi-motion turnout, the method comprises the following steps: a) network communication configuration of a first dynamic switch and a subsequent multiple dynamic switch, b) a mapping table of commands and representation information. The control parameters for each switch machine should include: a) the starting delay time is 0 for a scene that one turnout is pulled by one point switch, and the starting delay time is configured according to the starting sequence and can be adjusted within 50-250 milliseconds for a scene that one turnout is pulled by a plurality of point switches together. b) The start-up timeout, which should be compatible, is typically 13 seconds/30 seconds.
And the basic function of the communication module comprises distributing configuration data, sending the data combination of the turnout control module to the host equipment, and sending a command of the host equipment to the turnout control module. The functions to be realized are as follows: for a scenario where a switch is pulled by a switch machine, the switch control commands are directly mapped to the switch machine control commands, and the switch machine representations are directly mapped to the switch representations. For a scene that one turnout is jointly pulled by a plurality of point switches, a command sent by a host device needs to be read, a point switch control command is generated according to a turnout-point switch mapping relation in configuration data, and the command is sent to each turnout control module; reading the starting identifier of each switch, and if the switch cannot be started after a predetermined time (set in configuration data), transmitting a cutting command to all switches; and setting the indication information of the turnout according to the indication information of all the switch machines. For the use scene of the multiple-action turnout, firstly, the operation of the first movable turnout is completed within the overtime time, after the first movable turnout is in place, an action command is sent to the second movable turnout, and after the first movable turnout is completed within the overtime time, the command is continuously sent to the subsequent turnout until all turnouts are in place. If any turnout is not in place within the overtime time, the turnout is immediately stopped and all outputs are cut off. And setting switch indication information according to all switch indications.

When the turnout control module receives a command of cutting off the output, the turnout control module directly stops the rotation of the switch machine. (2) If the switch machine can not be started within the overtime time, the switch control module should cut off the power supply of the switch machine and send a sign of abnormal starting to the internal bus. (3) For a switch machine that is operating normally (no-jam, no-stick), once the switch machine is started, the switch machine may continue to be driven until the action is completed even if the control command to the switch machine is interrupted or stopped at that time. (4) When receiving a driving command in the opposite direction in the process of driving the switch machine, the turnout control module controls the switch machine to drive in the opposite direction. (5) If the switch machine can not rotate in place within the overtime time, the turnout control module stops driving the switch machine after the overtime. (6) Once the switch machine stops due to abnormal conditions, the switch machine is not allowed to be restarted until the switch machine is overhauled, and the system is restarted. (7) The representation information of the switch machine is collected and sent to the internal bus, and the non-representation information is provided during driving.

(1) system initialization, self-checking and configuration data checking.
(2) And periodically performing self-checking, and if a fault occurs, cutting off the output and reversing to a safety side.
(3) The communication module receives the control command from the main control equipment, judges whether the command is an effective combination, and analyzes the control command of the main control equipment according to the configuration data of the configuration file to generate the control command of the switch machine if the command is the effective combination. And after receiving the command, the turnout control module checks whether the command is a positioning operation command or a reverse operation command, sets timeout time and delay starting time according to configuration data in a configuration file, checks the state of the turnout switch and starts a timer. When the starting time is up, the driving circuit of the switch machine is switched on, and the switch machine is started to be driven until the switch machine is driven in place. The turnout control module acquires the state of the turnout switch, if the turnout switch is not started or does not act in place within the overtime, the turnout switch circuit is cut off, the driving state abnormity is sent to the communication module, the communication module checks the validity of the driving state and then sends a cut-off command to the rest turnout control modules, and the rest turnout control modules execute the cut-off command after checking the validity of the command.
(4) The turnout control module continuously collects the indication information and sends the indication information to the communication module, the communication module checks whether all the point switches are positioned, and if the point switches are positioned, the turnout general indication is set as a fixed table. If not, checking whether all the switch machines are in the reverse positions, if so, setting the turnout total representation as a reverse table, and otherwise, setting the turnout total representation as a loss representation.

(1) obtaining a switch machine control command from the internal bus, and operating the switch machine to operate on the set operation or the reverse operation according to the command; starting in a delayed mode according to the delay time set in the configuration data; when the turnout control module receives a command of cutting off output, the turnout control module directly stops the rotation of the point switch;
(2) if the point switch can not be started within the overtime time, the turnout control module cuts off the power supply of the point switch and sends a sign of abnormal starting to the internal bus;
(3) for the switch machine with normal working state, once the switch machine is started, even if the control command to the switch machine is interrupted or stopped at the moment, the switch machine is continuously driven until the action is finished;
(4) when receiving a driving command in the opposite direction in the process of driving the point switch, the turnout control module controls the point switch to drive in the opposite direction;
(5) if the point switch cannot rotate in place within overtime, the turnout control module stops driving the point switch after overtime;
(6) the representation information of the switch machine is collected and sent to the internal bus.
8. The switch control system for single or multiple switch machine trailed in claim 7, wherein the switch machine is not allowed to restart until re-maintenance once it has been stopped due to abnormal conditions.
9. A method of using the switch control system for single or multiple switch machine trailed in claim 1, characterized by the steps of:
(1) initializing a system, performing self-checking, and checking configuration data;
(2) periodic self-checking, if a fault occurs, cutting off the output and reversing to a safety side;
(3) the communication module receives a control command from the main control equipment, judges whether the command is an effective combination, analyzes the control command of the main control equipment according to the configuration data of the configuration file to generate a control command of the point switch if the command is the effective combination, and sends the control command of the point switch to the point switch control module; when the starting time is up, the switch machine driving circuit is switched on, and the switch machine is started to be driven until the switch machine is driven in place; the turnout control module acquires the state of a switch machine, if the turnout control module is not started or does not act in place within overtime, the switch machine circuit is cut off, the communication module sends abnormal driving state, the communication module checks the validity of the driving state and then sends a cut-off command to the other turnout control modules, and the other turnout control modules execute the cut-off command after checking the validity of the command;
(4) the turnout control module continuously collects the representation information and sends the representation information to the communication module, the communication module checks whether all the point switches are positioned, and if all the point switches are positioned, the turnout total representation is set as a fixed table; if not, checking whether all the switch machines are in the reverse positions, if so, setting the turnout total representation as a reverse table, and otherwise, setting the turnout total representation as a loss representation.
