Fig. 7 is a schematic structural diagram ii of a train switch control system according to a fourth embodiment of the present invention. As shown in fig. 7, in order to further improve the reliability and safety of the control system, a standby control device 2 having the same structure as the main control device 1 may be used, that is, the standby control device 2 also includes a main controller and a sub controller. The data interaction and judgment processing modes between the master controller and the slave controller in the standby control device 2 are the same as those of the master control device 1, and can be realized by referring to the above technical scheme, which is not described herein again.
The master control device 1 and the standby control device 2 are connected through a data bus, and the two devices are redundant. The master control device 1 and the standby control device 2 perform data interaction through a data bus so that work tasks of the master control device and the standby control device are kept synchronous, and fault information is updated synchronously. The master control apparatus 1 and the standby control apparatus 2 operate simultaneously, but when the master control apparatus 1 is in a normal operation state, only the master control apparatus 1 can output a control instruction for controlling the actuator 3. Fault information is mutually transmitted between the main control device 1 and the standby control device 2 through a data bus, and when a fault occurs in the main control device 1, a message is transmitted to the standby control device 2, so that the standby control device 2 replaces the main control device 1 to output a control instruction to control the actuating mechanism 3. If the main control device 1 and the standby control device 2 both have faults, the whole turnout control system is stopped. The standby control device 2 is used as a redundant control device, so that the reliability and the safety of the turnout control system can be improved.
In addition, in the process of controlling the operation of the system, the main control device 1 and the standby control device 2 can alternately operate according to a set period, and output a control instruction to the execution mechanism. Specifically, the master control device 1 and the standby control device 2 switch to operate at set time intervals. Namely: the master control device 1 works and outputs a control instruction to the execution mechanism, and the standby control device 1 only carries out data interaction and synchronous update with the master control device 1 and does not output the control instruction to the execution mechanism; after the time is set, the standby control device 2 is switched to work and control instructions are output to the execution mechanism, the main control device 1 only carries out data interaction and synchronous updating with the standby control device 2, and the control instructions are not output to the execution mechanism. The adoption of the scheme has the advantages that the main control device 1 and the standby control device 2 alternately operate and output control instructions to the execution mechanism so as to avoid the problem that the electronic device in one device is easy to generate faults because the electronic device does not work for a long time.
It is understood that when one of the master control apparatus 1 and the standby control apparatus 2 is in a failure state, the above switching between the two is not required.
Fig. 8 is a schematic signal flow diagram of a control method according to a fourth embodiment of the present invention. As shown in fig. 8, switches provided at two respective signal input terminals of the master controller 11 and the slave controller 12 perform an opening and closing operation according to the same switch control signal, so that the two respective signal input terminals of the master controller 11 and the slave controller 12 receive the first level signal and the second level signal, respectively.
The main controller 11 is provided with a first judging module 113, a first processing module 114 and a control instruction generating module 115; a second judgment module 123 and a second processing module 124 are provided in the slave controller 12. The first judging module 113 judges the first level signals received by the two signal input ends and generates a first judging result; the second judging module 123 judges the second level signal received by the two signal input ends, and generates a second judging result.
Then, the master controller 11 and the slave controller 12 exchange the first determination result and the second determination result with each other. So that the first processing module 114 and the second processing module 124 both determine whether the first determination result and the second determination result are the same, and generate a first processing result and a second processing result, respectively.
Thereafter, the slave controller 12 transmits the second processing result to the master controller 11, so that the control instruction generation module 115 determines whether the first processing result and the second processing result are the same, and generates a control instruction for controlling the actuator.
According to the scheme, the main controller 11 and the slave controller 12 are adopted to perform data interchange and judgment for many times, so that the accuracy and timeliness of fault finding can be improved, and the reliability and safety of the turnout control system are further improved.

the slave controller judges whether the first judgment result and the second judgment result are the same; if so, generating a control value as a second processing result; if not, generating a fault value as a second processing result.
10. The control method of the train switch control system according to claim 4, further comprising:
the slave controller receives an action feedback signal sent by the actuating mechanism;
and the slave controller judges whether the action of the executing mechanism meets the set requirement or not according to the action feedback signal, and generates a fault signal if the action of the executing mechanism does not meet the set requirement.
11. A train switch control system characterized by performing the control method according to any one of claims 1 to 10.
12. A computer device comprising a memory, a processor and a computer program stored on the memory and executable on the processor, the processor implementing the method according to any one of claims 1-10 when executing the program.
13. A non-transitory computer-readable storage medium, on which a computer program is stored, which, when executed by a processor, implements the method of any one of claims 1-10.
