Description

Safety control device for automatic door by infrared safety sensor {Safty control apparatus for automatic door}

The present invention relates to an automatic door safety control device using an infrared safety sensor, and more particularly, a sensor sensor unit mounted with an infrared light emitting element and an infrared light receiving element in one housing is installed on the lower side of the upper door frame of the automatic door, It emits a cone-shaped infrared beam through the light emitting element and detects objects within 1.5m of the automatic door, so that the automatic door safety control device can be prevented from crashing or pinching the automatic door even when the automatic door is closed. It is about.

In general, a residential house usually does not enter many people, so manual doors of sliding doors or sliding doors are usually installed. However, as well as large buildings such as office buildings, hotels, hospitals, etc. In the case of buildings, revolving doors or automatic doors are installed. Among the types of automatic doors, automatic doors open and close automatic doors automatically by detecting a person's approach, so it is natural that safety devices should be installed in case of accidents. something to do.

Referring to the configuration of the automatic door control device according to the prior art for automatically opening and closing the automatic door as described above, it is installed on the lower side of the upper door frame of the automatic door to a certain area adjacent to the automatic door. Motion sensor to detect its motion when it comes in, controller to generate open control signal of automatic door through input of detected signal of motion sensor, and open automatic door according to open control signal of automatic door by controller When the motor driving unit (Open) and a person or an object does not completely pass through the automatic door outside the detection area of the motion sensor unit, the automatic door is closed to prevent the closing of the door.

On the other hand, the automatic door control device according to the prior art configured as described above, when a person or other object enters a certain range area on the front side of the automatic door, the motion sensor unit detects the motion of a person or object that has entered a certain range area. It will detect it and send it to the controller. As such, the controller outputs an open control signal of the automatic door to the motor driving unit according to the detection signal of the motion sensor unit according to the motion detection of a person or an object so that the automatic door can be opened.

In the technology of the automatic door control device according to the prior art as described above, the safety sensor unit prevents the automatic door from closing when a person or an object does not pass through the automatic door outside the detection area of the motion sensor unit. Of course, even when a person or object suddenly jumps between the automatic doors in the process of closing the automatic doors, the safety sensor detects this and allows the automatic doors to be reopened, thus preventing people or styles from being caught between the automatic doors. .

In the technology of the automatic door control apparatus according to the prior art as described above, the configuration using the safety sensor can be said to be the most common technology using infrared.

Consists of the configuration. When the infrared light emitted from the infrared light emitting device is not received by the infrared light receiving device, the safety sensor unit according to the related art is transmitted to the controller as a signal, so that the controller recognizes that there is a person or an object between the automatic doors. Therefore, the automatic door is prevented from being closed (close) or in the case of the automatic door in the closing process (Close), the automatic door is controlled to open (Open).

However, in the case of the infrared safety sensor according to the related art as described above, since the infrared light emitting element and the infrared light receiving element are arranged on the same line on both sides of the automatic door, the detection range of the object is limited to linear detection. The disadvantage is that the detection range is very small. Therefore, in the case of the infrared safety sensor according to the prior art, there is a problem in that accidents that occur in the automatic door frequently occur due to the disadvantage that the object can only be detected between the automatic doors.

In particular, the cases of safety accidents caused by automatic doors surveyed by the Korea Consumer Protection Agency showed 9 cases in 2005, 11 cases in 2006, and 20 cases in 2007. It would be natural that there would be many examples if we included facts and similar experiences. In addition, as the result of the damage case, as the spread of automatic doors increases, the safety accidents of automatic doors can be known to increase rapidly, so more effective safety measures are urgently needed.

On the other hand, when the infrared safety sensor according to the prior art as described above is installed on the automatic door, in order to install the infrared light emitting device and the infrared light receiving device, it is necessary to make perforations on both sides of the automatic door as well as the wiring work is required accordingly.

At this time, the lower lower region of the sensing region A, which is emitted from the infrared light emitting element 112a and is formed in a cone shape, emits light in a range that allows the object to be detected within a range of 1.5 to 2 m before and after the automatic door 140. Thus, the sensing area A is configured.

In other words, the automatic door safety control device by the infrared safety sensor emits an infrared beam downward through the infrared light emitting element 112a of the safety sensor unit 110 installed on the lower surface of the upper door frame 142 of the automatic door 140. To form a cone-shaped detection area (A). Therefore, compared with the linear sensing according to the prior art, the sensing area A is widened, thereby preventing accidents such as an object colliding or pinching the automatic door 140 in advance.
