Embodiment 1

[0046] Such as figure 1 ,and Figure 3 to Figure 6 As shown in the figure, a control system for subway shielded door staggered start, including a sub-controller and an actuator, each shielded door corresponds to an actuator, the actuator is connected to the shielded door, each shielded door corresponds to a sub-controller, and the sub-controller is divided into The controller can be built into the screen door or externally installed on the screen door, and the sub-controller is used to receive the door opening or closing control command sent by the main controller. The main controller is electrically connected to the sub-controllers to send control commands to the sub-controllers. The control commands include door opening control commands or door closing control commands. The sub-controllers are electrically connected to the actuators. The actuators are used to pull the screen door for mechanical displacement. Thereby controlling the opening and closing of the screen door, th...

Embodiment 2

[0082] Embodiment 1 is that when the sub-controller receives the control command of opening or closing the door sent by the main controller, the delay timing unit starts timing and obtains the timing value, which belongs to forward timing; the difference from Embodiment 1 is that This embodiment adopts the countdown method, and the specific implementation process is as follows:

[0083] Such as Figure 2 to Figure 5 A control system for peak staggered starting of subway screen doors is shown, including sub-controllers and actuators, each screen door corresponds to an actuator, the actuator is connected to the screen door, and each screen door corresponds to a sub-controller, sub-controller The controller can be built-in or external on the screen door, and the sub-controller is used to receive the door opening or closing control command sent by the main controller. The main controller is electrically connected to the sub-controllers to send control commands to the sub-controll...

Abstract

The invention relates to a control system for off-peak starting of metro platform screen doors. All the platform screen doors are grouped. The control system comprises a subsidiary controller and an executor. The subsidiary controller is used for receiving door opening and closing control commands sent by a main controller. The executor controls opening and closing of the platform screen doors. Each platform screen door is provided with a corresponding delay timing unit. Timing starts after the subsidiary controller receives the door opening or closing control commands, and one corresponding timing time value is obtained. The subsidiary controller comprises a preset amount generation unit for generating reference time, a data storing unit for storing the reference time, a comparing unit for comparing the current timing time value with the reference time value to get a command whether to allow the executor to be started, and the executor used for pulling the corresponding platform screen doors to carry out mechanical displacement. The control system can effectively reduce the electromagnetic interference intensity, meanwhile, the situation that due to the fact that currents startedinstantly are too large, equipment or parts such as a motor, a drive cable and a drive power source are impacted can be avoided, and the service life of the equipment is prolonged.

Description

technical field [0001] The invention relates to the technical field of control of subway screen doors, in particular to a control system for peak-staggered start of subway screen doors. Background technique [0002] There are usually multiple screen doors on one side of a subway platform. At present, 24-40 screen doors are used on most sides. When a subway train enters or leaves the station and needs to open or close the screen doors, the control system simultaneously Send the door opening or closing control command, without considering the transmission delay of the door opening or closing control command (this is in line with the actual situation, because the actual circuit from the main controller that sends the control command to the shielded door is very short, and its transmission The time delay can be neglected), and each screen door receives the door opening or closing control command at the same time and starts at the same time. However, the current of the screen do...
