BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an automatic door opening / closing control device for opening an automatic door by operating a start switch generally called a touch switch.

[0002]

2. Description of the Related Art In recent years, as an automatic door opening / closing control device, a device using a passive infrared sensor which can easily set and change a detection area as a start switch has been generally adopted. This device detects the human body by using the fluctuation of the radiated infrared light flux based on the temperature difference between the background of the detection area set by the optical system that collects the infrared light flux and the human body that has entered the detection area, and detects the automatic door. Is controlled to open and close.

By the way, when there is almost no space in front of the automatic door or when the automatic door is installed facing the street, the automatic door using the non-contact type passive infrared sensor as described above is used. The adoption of the opening / closing control device causes a disadvantage that a person other than a person passing through the door, for example, a person who simply passes by the side of the automatic door or a mere passerby is detected and the automatic door is opened each time. For an automatic door provided in such a place, an automatic door opening / closing control device using a so-called touch switch such as a mechanical switch or a capacitance type switch as a start switch is provided. The automatic door opening and closing control device using the touch switch as a start switch opens the automatic door when the start switch is turned on.
The opening and closing of the door is controlled so that the automatic door is closed after a set time of seconds. However, when the human body slowly walks and tries to pass through the automatic door in a time longer than the set time described above, or when the user talks between the opened automatic doors, the start switch is turned on. Since the closing operation of the automatic door is started after a lapse of the set time, the automatic door starts to close when the automatic door is attempted to pass.

Therefore, in order to ensure safety, a safety sensor for detecting whether or not a human body is between the automatic doors is provided in the vicinity of the automatic door, separately from the above-mentioned start switch.
A device for controlling the opening and closing of the automatic door by combining the start switch and the safety sensor has been proposed. This device is
When the start switch is turned on, the automatic door is opened, and a human body passing between the opened automatic doors is detected and the safety sensor is turned on.If the safety sensor is on, the set time described above has elapsed. Even when the door is kept open, for example, a person standing between the opened automatic doors is kept open to give a sense of security.

[0005]

However, the automatic door opening / closing control device provided with the above-mentioned safety sensor still has a problem which must be solved in terms of safety.
This will be described with reference to FIGS. 7 and 8, each (a) shows a moving position of the human body passing through the automatic door, A is a position where the start switch can be operated, and B is a position detected by the safety sensor. Also,
(B) shows the operating state of the start switch, (c) shows the operating state of the safety sensor, and (d) shows the open / closed state of the automatic door. Then, as shown in FIG. 7A, if the human body tries to walk slowly through the automatic door after operating the start switch, the set time (t1) elapses before being detected by the safety sensor. As shown in FIG. 4D, the closing operation of the automatic door is started, and it is very difficult to immediately operate the start switch moving together with the automatic door during the closing operation. In the above, there is a possibility that the user may be unnecessarily surprised by being caught by the automatic door or hitting the automatic door.

Also, as shown in FIG. 8 (a), when the human body operates the start switch to open the automatic door and then stops on the spot and starts talking, for example.
If the user tries to pass through the automatic door in a hurry after the set time (t1) has elapsed and the automatic door closing operation has started as shown in FIG. Since the door is closed, a person trying to pass through the automatic door over the time period indicated by t3 may be uneasy.

Accordingly, the present invention provides a control that opens the automatic door for a minimum time, which is sufficient to provide safety and provide a sense of security according to the moving speed of a human body or the like passing through the automatic door. It is an object of the present invention to provide a simple automatic door opening and closing control device.

[0009]

[0010]

The automatic door is opened when the start switch is operated and turned on, and the safety sensor detects a human body passing between the opened automatic doors and outputs a detection signal.
Unless this detection signal is output from the safety sensor, the automatic door is kept open, so even if the user walks slowly through the automatic door or stops near the open automatic door, the door closes by the person. the trouble is sandwiched between can prevent. When the detection signal from the safety sensor human body through the door is not outputted, the controller at that time is controlled to close the automatic door. Therefore, since the automatic door is controlled to be closed when the human body has passed through the automatic door, regardless of the moving speed of the person passing through the door, the trouble that the human body is caught by the automatic door can be solved.

In the case where no human body detection signal is input from the safety sensor within a certain period of time after the automatic door is opened,
So it was to close the automatic door after a certain period of time has elapsed, if the intention to pass through the automatic door has been operated start switch in the mischief to no, automatic door is opened until the next human body to pass through the automatic door It is possible to prevent continued inconvenience.
