Therefore, whether the target position of the turnout beam is correct or not is determined according to the first closing times recorded by the first counter and the second closing times recorded by the second counter, the phenomenon that two travel switches are required to be arranged at each turnout position is avoided, the number of the travel switches in the conventional turnout control system can be effectively reduced, the reliability of the turnout control system can be effectively improved, and meanwhile, the installation and maintenance cost of the turnout control system is reduced.

In this step, if it is determined that the driving motor is in the first rotation direction, steps 305 and 307 are performed; determining that the drive motor is in a non-first rotational direction; steps 306 and 308 are performed.
It should be noted that, the first counter and the second counter are both arranged on the turnout beam, the first counter and the second counter are respectively connected with the controller, and the first counter is used for recording the first closing times; the second counter is used for recording a second closing time.
And 308, controlling the second value of the second counter to be reduced by the first preset value.
It should be noted that the first value is a count value of the first counter; the second value is the count value of the second counter.
in this step, if the first closing number is equal to the second closing number, that is, the count value of the first counter is equal to the count value of the second counter, step 311 is executed; if the first closing times and the second closing times are not equal, step 312 is performed.
And 311, controlling the locking mechanism to lock the travelling mechanism.
The locking mechanism is arranged on the traveling mechanism, connected with the controller and used for locking the traveling mechanism so as to fix the turnout beam at the target position, wherein the target position is one of a plurality of turnout positions.
And step 312, determining that the turnout beam has a fault.
It should be noted that when the target position where the turnout beam is located is determined to be wrong, it is determined that the turnout beam is in fault, and when it is determined that the turnout beam is in fault, an alarm can be awakened in a preset alarm mode to attract the attention of workers.
Therefore, whether the target position of the turnout beam is correct or not is determined according to the first closing times and the second closing times, two travel switches do not need to be arranged at each turnout position, the number of the travel switches in the conventional turnout control system can be effectively reduced, the reliability of the turnout control system can be effectively improved, and meanwhile, the installation and maintenance cost of the turnout control system is reduced.
