Problems solved by technology
[0002] The original screen door system adopts a distributed IO system, and the information of the four unit doors is equipped with a control acquisition system, which makes the wiring construction inconvenient, and the model specifications of the electrical components of the platform door unit doors are not uniform on one side (for example, there are 24 unit doors on one side, Among them, 6 sets are equipped with control collectors, and the rest are not needed). In addition, the control part of the unit door control collection system is purely hardware control (opening and closing the door, electromagnetic lock unlocking, manual unlocking judgment, and light board control), which is relatively complicated. It is not easy to check, and the control method is not flexible. If the owner puts forward new control requirements, they cannot directly meet the requirements through convenient methods such as updating firmware
