Abstract: An inquiry processing device includes: an automatic door information recorder that records information including past inquiry information from a customer regarding an automatic door, an operation situation, and quality information; a countermeasure presenter that presents recommended countermeasure information corresponding to a new inquiry regarding the automatic door by an extraction algorithm; a feedback information receiver that receives feedback information on whether or not a defect of the automatic door has been removed by taking measures on the basis of the recommended countermeasure information; a learner that updates the extraction algorithm of the countermeasure presenter on the basis of the feedback information; and a countermeasure presentation determiner that causes the countermeasure presenter to present new recommended countermeasure information by the extraction algorithm updated by the learner, when it is determined that the defect of the automatic door has not been removed.

Abstract: An automatic door maintenance support system includes an acquirer that acquires state information of a motor which drives a door of an automatic door in a first speed control state in which the door is maintained at a predetermined first speed, and a specifier that specifies information regarding maintenance of the automatic door by comparing the acquired state information with a predetermined reference value. An automatic door maintenance support method includes a step of acquiring state information of a motor which drives a door of an automatic door in a speed control state in which the door is maintained at a predetermined speed, and a step of specifying information regarding maintenance of the automatic door by comparing the acquired state information with a predetermined reference value.

Abstract: An operation mode switching device for switching an operation mode of an automatic door includes a display for displaying a home screen for displaying the current operation mode and an icon display control unit for executing a control to display an icon indicating the current operation mode in color on the home screen. Thus, the operation mode of the automatic door can be confirmed even at a remote position.

Abstract: Provided are a management system and management method for an automatic door apparatus, with which it is possible to easily recognize the working circumstances of an automatic door apparatus and also possible to easily ensure security without incurring management costs for a selling company or a maintenance company. A management system for automatic door apparatuses comprises: the automatic door apparatuses with which communication is possible; a management server disposed within a narrow-area network of the customer-side management system identical to the automatic door apparatuses and capable of checking the working circumstances of the automatic doors by communicating with the automatic door apparatuses; and a management PC disposed within a wide-area network outside the narrow-area network and capable of communicating with the management server by remote desktop technology; wherein the management PC acquires the working circumstances of the automatic door apparatuses via the management server.

Abstract: A light-emitter emits light into a door opening of an automatic door system. A light-receiver receives light from the light-emitter which has passed through the door opening and develops a light-reception indicative signal. A door controller causes the light-emitter to stop emitting light and, thereafter, start emitting light. An auxiliary sensor is judged to be operating in order when the light-receiver does not develop light-reception indicative signal in a state where the light-emitter is not emitting light, and, thereafter, develops a light-reception indicative signal when the light-emitter resumes emitting light; otherwise, the auxiliary sensor is judged to be out of order.

Abstract: Whether interruption is present in the connections of automatic door constituting units is detected. A plurality of automatic door constituting units (4, 8, 10, 12, 20, 24 and 26) are interconnected in such a manner that they can communicate with each other via a bus (2). The automatic door constituting units include a door controller (4) for controlling opening and closing of a door. The door controller (4) successively calls the other automatic door constituting units one by one via the bus (2), and the other automatic door constituting units send a response to the calling via the bus (2). The door controller (4) judges that the automatic door constituting unit the door controller (4) called is disconnected from the bus (2), when said called automatic door constituting unit does not send a response within a predetermined time after the calling.
