Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a method for controlling the opening and closing of a sliding or swinging automatic door.

Automatic door opening/closing uses mechanical switches such as mud switches, pedal switches, touch switches, and pull switches, as well as non-contact types such as heat-sensitive, infrared, ultrasonic, and radio waves, to detect the presence of objects such as passersby. Generally, the object is detected by a passing object detection device such as a switch, and a door opening signal is issued by this detection, and the door is opened or closed by this opening signal.

Incidentally, in buildings equipped with automatic doors, the interior of the building is often air-conditioned, such as heating and cooling.

In such buildings, if the automatic doors are opened and closed frequently, the cold or warm air inside the building will be dissipated through the automatic doors to the outside, reducing the effectiveness of air conditioning and increasing electricity costs for air conditioning. There's a problem.

Therefore, in order to minimize the decrease in the 9-tone effect as described above, the speed of automatic door movement is increased, or the automatic door control device is equipped with a microcomputer to control the opening and closing of the door. Methods such as reducing the opening width of the door (leaving it half-open) depending on the number of times the door is opened are being considered. However, with doors that move at a faster speed, infants, elderly people, etc. who are slow to move may get caught in the door, and those equipped with a microcomputer are expensive and need to be opened/closed many times. Since the opening width is made smaller, there are drawbacks such as large objects passing through the door cannot pass through the door.

This invention was made in view of the above circumstances, and is an automatic system that detects the size and direction of passing objects, controls the opening width of automatic doors based on this information, and minimizes the decline in air conditioning effectiveness. In order to provide a door opening/closing control method, a plurality of passing object detection devices are substantially provided to generate a plurality of door opening signals, and these door opening signals are used to determine the size and direction of the passing object. This system is characterized by detecting the opening signals and controlling the degree of opening of the door based on these opening signals.

The mud switch 11 is installed on the floor surface of the automatic door body 12 on the door entrance side and the exit side, respectively, as shown in FIGS. It is essentially the same as three independent mud switches lined up, as shown in the figure, and the center contact S
If only A is turned on, it is detected that the passing object is seven passersby or a small passing object, and if side contact SB or side contact SB and center contact SA are simultaneously KON. The passing object is 2 to 3 passersby or a large passing object or the passing direction is a door 13.13
It is detected that it is oblique to the Therefore, the mud switch 11 can detect the substantial size and direction of a passing object, and can issue two types of door opening signals in conjunction with this detection.

This mud switch 11 is combined with a sliding automatic door body 12 shown in FIG.

The opening frame 14 of this sliding automatic door body 12 is formed by an upper blind 15 and vertical frames 16 and 16 on the left and right sides, and a door hanging p1 knob 17 is attached along this blind 15 to open the door. 13.13 (7) Door hanging metal fittings 18.18

FIG. 5 shows an example of a control circuit for controlling the opening and closing of the automatic door body 12 described above, and shows a state in which the door 13.13 is stopped at the closed position as shown in FIG. That is, when the closed position detection switch 26 is turned on, the closed position stop 1/no X3 operates, and the motor circuit that rotates the door 13, 13 in the closing direction is turned off. Next, when a passerby or the like steps on the upper center electrode plate 3 of the mud switch 11, the center contact SA turns ON, the motor forward/reverse switch 1/NO X1 operates, and the motor 23 switches to the door 13.
13, and the doors 13, 13 begin to open. When the door 13.13 opens to the position where the half-open position detection switch 25 turns ON, the open position stop 1 NO X4 operates, and the motor circuit that rotates the door 13.13 in the opening direction turns OFF. .13 stops at a halfway open position (hereinafter referred to as the "half open position") before reaching full open. Then, when a passerby passes through the door 13, 13 and leaves the mud switch 11 on the opposite side, the motor forward/reverse switching 1/no Xi and the half-close switching 1/no X2 are restored, and the motor 23
rotates in the closing direction of the door 13.13, and the door 13.13 begins to close. When the closed position detection switch 26 is turned on, the closed position stop IJl/-xa is activated, and the door 13.13 is stopped at the closed position shown in FIG.

In addition, when two or three passersby pass at once, when a large passing object such as a car passes, or when passersby approaches the door 13.13 diagonally, The side contact SB or the side contact SB and the center contact SA of the mud switch 11 are turned on. Then, the motor forward/reverse switch 1 NO X1 and the half open switch 1 NO X2 operate, the motor 23 rotates in the opening direction, and the door 13.13
begins to open. The position detection switch operator 27 turns on the half-open position detection switch 25 while the door 13.13 is fully open, but the contact of the half-open switch I/-X2 opens and goes out, so the open position stop 11 is disabled. X4 does not work,
Door 13.13 continues to open.

When the door 13.13 reaches the fully open position, the fully open position detection switch 24 is turned on, the open position stop 1/NO X4 is operated, and the motor 23 is stopped. When a passing object passes and leaves the mud switch 11, the door 1 is closed in the same manner as described above.
3.13 is closed.

As described above, in this example, the mud switch 11 is divided into three sections, and similar to the case where three independent mud switches are provided, there are two types of mud switches depending on the actual size and direction of movement of the passing object. A door open signal of 1 is generated, and this kind of door open signal causes door 1 to be
Since the opening width of the door 13.13 is selected to be fully open or half open, the opening degree of the door 13.13 can be controlled in accordance with the substantial size and direction of movement of the passing object.
As wasteful opening of 3 is eliminated, there is little chance of cold or warm air escaping from the door 13, 13, and the deterioration of the tone effect is minimized. Moreover, the power cost for opening and closing the door 13.13 can also be reduced.

By providing such an ultrasonic switch 32, 33, 34, if only the center contact SA is turned on, it is detected that the passing object is seven passersby or a physical object with a small width. If side contact SB or side contact SB and center contact SA are turned on at the same time, two or more passing objects
It is detected that there are three passers-by, a large passing object, or that the vehicle is oblique to the traffic direction Katoa 13.13. Therefore, the mud switch 11 can detect the substantial size and direction of the passing object, and in conjunction with this detection, can issue two door opening signals.

The automatic door main body 12 is operated by the ultrasonic switches 32, 33, and 34 in the same manner as in the above-mentioned example, and the same effects can be obtained.

In addition, instead of an ultrasonic switch, it is possible to install multiple single-node switches that use an X-pantominomagnetic beam, infrared switches that use an infrared light beam, and heat-sensitive switches that detect long-wavelength infrared light emitted by passing objects. The effects of this can be obtained.
