A special detection area in which detection in accordance with an activation detection algorithm for detecting a person or an object and detection in accordance with a protection detection algorithm having a higher detection sensitivity for the person or the object than the activation detection algorithm are performed is provided. Results of the detections in accordance with the activation detection algorithm and the protection detection algorithm are individually output to an automatic door device.

Automatic door sensor, automatic door system, and method of controlling automatic door system

A detecting unit () forms a plurality of detection spots arranged two-dimensionally on a floor surface near a door panel (). Each detection spot is capable of detecting a human or an object by infrared light independently from other detection spots. Region distinguishing means () distinguishes a region formed by plural ones of the said detection spots that have detected the human or object. Person's movement judging means () judges the direction in which the distinguished region moves. A signal which causes a door panel () to be opened is supplied to a door controller () only when the direction of movement of the distinguished region is the direction toward the door panel.

Sensor for use with automatic door

Disclosed is a system for monitoring automatic door apparatuses installed at different sites by centrally administering maintenance service contents and contents regarding actual repair to compile a database and by rendering personnel in sales agents or maintenance service agents accessible to the database. The system has a multitude of automatic door apparatus each having a communications function, and an administration center communicatively connected with the respective automatic door apparatuses via a communication medium. Each of the automatic door apparatuses sends, to the administration center, operating information of its own with apparatus identification information attached thereto. The administration center is operative to classify the operating information of each door apparatus into a number of categories based on the apparatus identification information for storage, and to output the operating information in response to a calling.

Method and system for administering automatic door apparatus, and automatic door apparatus

An automatic door system includes a door which id driven to open and close by a motor. A sensor senses an object which approaches or leaves the door. A control section controls the motor in accordance with a signal supplied from the sensor. The control section includes a CPU which examines the motor, the sensor and the control section for failure or malfunction, and also an EEPROM which stores the result of examination made by the CPU. The result of examination stored in the EEPROM is outputted to a Handy Terminal or a personal computer.

Automatic door system with self-diagnosing function

An automatic door system includes a motor which drives a door to open and close. A CPU operating in accordance with a signal from an encoder operatively coupled to the motor detects the position of the door and prepares and applies a control signal based on the detected door position to a motor drive unit. The motor drive unit alternately drives and brakes the motor. The CPU calculates the speed of the door at a particular door position on the basis of the signal from the encoder and operates to make the door speed equal to the aimed speed for the current door position.
