Abstract:

[PROBLEMS] To detect disconnection in automatic door constitutive devices. [MEANS FOR SOLVING PROBLEMS] A plurality of automatic door constitutive devices (4, 8, 10, 12, 20, 24 and 26) are connected to communicate with each other through a bus (2). The automatic door constitutive devices include a door controller (4) performing open/close control on the door. The door controller (4) calls other automatic door constitutive devices sequentially through the bus (2), and other automatic door constitutive devices respond to the call through the bus (2). When a called automatic door constitutive device does not respond to the calling within a predetermined time, the door controller (4) judges that the called automatic door constitutive device is disconnected from the bus (2).
