What is the principle of the front and rear automatic doors of BRT platform doors? It seems to be related to the opening and closing of the bus, but once I saw the door of the bus open, but the platform didn't open, and it opened again when someone touched it. If so, why does the opening time of each platform door coincide with that of the bus door?

Automatic door of BRT bus stop, i.e. induction automatic door.

The synchronous belt wheel is driven by stepping motor, and the synchronous belt drives the whole door to open and close. After the vehicle arrives, the bus will give an automatic door opening signal to realize automatic opening. After the door is closed, the automatic door of the platform will be closed automatically.

In the process of opening and closing, the warning light flashes and whistles to remind passengers to pay attention to safety. A grating is set at the joint of the door, which will stop immediately in case of abnormality. The model is drawn by sw2014.

The system configuration of automatic door refers to the peripheral auxiliary control devices equipped according to the use requirements and connected with the automatic door controller, such as door opening signal source, access control system, safety device, centralized control, etc.

It must be based on the use characteristics of the building. Auxiliary control devices shall be reasonably equipped through the composition of personnel and the requirements of building automatic control system. Induction automatic doors are widely used in hotels, airports, business clubs, high-end communities and other places.
