The invention relates to the technical field of automatic doors, and provides an automatic door, an automatic door control method, a control device and a train. The control method comprises the stepsthat the opening and closing state of the automatic door is obtained; when the automatic door is in a closed state, whether a trigger object exists in a first detection area or not is judged; if the trigger object exists in the first detection area, the automatic door is controlled to be opened; when the automatic door is in an opened state, whether a trigger object exists in a second detection area or not is judged; if the trigger object exists in the second detection area, the automatic door is controlled to be kept in the opened state; and the first detection area is positioned in the second detection area, and the range of the first detection area is smaller than that of the second detection area. According to the method, whether the automatic door is opened or not is judged through the first detection area, whether the automatic door is closed or not is judged through the second detection area, and through the design, convenience of two or more persons continuously passing throughthe automatic door can be improved on the basis of avoiding mistaken opening of the automatic door.

The invention discloses a fire automatic door opening method of an Internet-of-Things intelligent door lock. The method comprises the steps that 1000, the indoor temperature is measured to be above afirst temperature threshold value, and the indoor smoke is measured to reach a first smoke threshold value; and 2000, all lock structures are opened so as to open a door. The first temperature threshold value is 55 DEG C or above. The first smoke threshold value is above 5%PBS/M and below 15%OBS/M. A temperature sensor and a smoke sensor are combined, specific parameters are set, and therefore thebeneficial effects that doors are opened at the early stage of fires, a mechanical unlocking mechanism is additionally arranged to avoid the situation that the door lock is closed due to failures ofelectronic devices, and it is guaranteed that doors are opened and not locked are achieved.

A remote control door closure operating system is based on a central server with a backend database identifying a collection of controllable doors and a plurality of authorized users and corresponding credentials. A door interface unit is adapted to communicate with an authorized user to supply a live video stream of a respective door and to execute door opening and closing commands from the authorized user. A mobile device has a user application program configured to interact with the central server and door interface unit in order to 1) obtain configuration data, 2) authenticate the authorized user, 3) receive the live video stream, and 4) initiate the door opening and closing commands. Safe operation of the door opening/closing operation is encouraged by maximizing use of video surveillance before and during door operations and by conducting separate security authentications for video streaming and for door operation requests.

A profile learning system for cooperative control of a dual actuator applied to opposite sliding doors may include a first position sensor configured to detect a position of a door that operates in a first direction along a rail; a spindle assembly including a spindle that operates in a second direction with respect to the door to prevent the door from rattling; first and second motors engaged to the door and the spindle assembly and configured to provide driving power to the door and the spindle assembly, respectively; a memory unit configured to store the position of the door; and a control unit configured to adjust an output of the second motor configured for a predetermined time period and to determine learning success or learning failure for complete opening or closing of the door based on the position of the door when a stall state is detected due to a difference in stroke between the first motor and the second motor.
