The present disclosure relates to a control method, a controller and a control system for a platform door. The method includes: when receiving a control command sent by an external device, synchronously acquiring the current phase of the first motor and the current phase of the second motor the current phase of the first motor; determine the set speed of the first motor according to the current phase of the first motor, and synchronously determine the set speed of the second motor according to the current phase of the second motor; according to the The set speed of the first motor and the current speed of the first motor to generate a first pulse width modulation PWM signal corresponding to the first motor, and synchronously according to the set speed of the second motor and the first motor The current speed of the second motor is used to generate the second PWM signal corresponding to the second motor; and the first PWM signal and the second PWM signal are sent to the first motor and the second motor synchronously, respectively. Thus, the synchronization of the two door bodies is high.
Description
technical field [0001] The present disclosure relates to the technical field of automatic control, in particular to a control method, a controller and a control system for a platform door. Background technique [0002] The screen door (platform door) is installed on the edge of the platform of the station along the rail transit line, and is used to isolate the platform waiting area from the track driving area. In the related art, the platform door adopts a control mode of one controller and one motor, one control and one machine, to control the two doors of the platform door, which makes the cost of the platform door high and the synchronization of the two doors is poor. Contents of the invention [0003] In view of this, the present disclosure proposes a platform door control method, controller and control system. [0004] According to the first aspect of the present disclosure, a platform door control method is provided, which is applied to the controller of the platfor...
