Description

Sensor device for detecting visitor and automatic opening and closing system of hinged door including same

The present invention relates to a sensor device for detecting a person approaching a casement door and an automatic opening and closing system for a casement door including the same, and more particularly, to selectively classify only a person moving near the door among people moving around the door, It relates to a sensor device for detecting a visitor and an automatic opening and closing system for a casement door including the same.

Automatic doors are installed in elevators, trains, screen doors, as well as airports, museums, buildings, apartments, and shopping malls, and when a user approaches the automatic door, a sensor detects it and automatically opens and closes the door.

In general, automatic door systems perform obstacle sensing for two purposes. First, for the purpose of safety to prevent the user from being caught in the door gap, short-range sensing is performed by focusing on the mechanically operated part of the automatic door. The second is to detect the user's entry and exit and open and close the automatic door at the right moment. To perform remote sensing.

1 is a view showing an automatic door system equipped with a conventional infrared sensor for controlling the driving of an automatic door.

Referring to FIG. 1 , a conventional automatic door system includes a long-distance sensor 100 and short-distance sensors 122 and 124 .

The remote sensor 100 is generally installed in front of a door or on a ceiling, and detects a change in the amount of infrared light by irradiating infrared rays within a predetermined range and measuring the amount of reflected light, thereby determining whether an object exists within the measurement area V. A range detection method is used. Due to the advantage of measuring a wider and farther distance, this range detection method is used as a means of detecting the user's entry and exit in the automatic door 130, but in the prior art, whether or not there is a pedestrian in the measurement area (V) It only judges the direction of movement and has a limit that cannot determine the location.

The short-distance sensors 122 and 124 are composed of a plurality of infrared radiating units 122 and a plurality of light receiving units 124, and infrared rays emitted from the infrared radiating unit 122 are input to the light receiving unit 124. In particular, when an object is located on the target measurement plane P through which infrared rays pass, since infrared rays are not input to the light receiving unit 124, it is determined that the object is located between the automatic doors 130 and the open state of the automatic door 130 is determined. keep

In this way, the sensors 100, 122, and 124 installed in the conventional automatic door system are used to prevent safety accidents in which the user is caught in the hinged door by the remote sensor 100 that detects the user's entry and exit to drive the automatic door 130 and the operation of the automatic door. As a result, the short-distance sensors 122 and 124, which mainly detect people entering and exiting the opening and closing doors, were used in parallel. In this case, even if a pedestrian moving around the automatic door 130 without passing through the automatic door 130 is detected, the automatic door 130 automatically opens.

In addition, when there is a fixed installation in the measurement area (Y), it is misunderstood as an obstacle, and a malfunction such as continuously opening a door is also caused.

In addition, in the case of using the sensor, since it is impossible to distinguish whether an object close to the automatic door is a person or not, there is a problem in that the automatic door is opened even when a dog or cat passes by.

That is, the infrared sensor generates entry information of an object when movement is detected from the front and rear of the hinged door, and then provides the information to the control unit 300 .

The radar sensor outputs a radar forward, receives a reflected radar signal, and obtains information of a pedestrian heading toward a hinged door according to the reflected radar signal.

The ToF sensor measures the distance to the target object by calculating the round-trip time taken when photons travel from the sensor to the object and vice versa. And the ToF sensor outputs 940nm light invisible to the human eye.

This ToF sensor can be set to multiple distance modes, and the maximum distance is set for each mode. For example, the ToF sensor can be set to short-range mode, medium-range mode, and long-range mode, and the maximum distances for each mode are 1360mm, 2900mm, and 3600mm for a white target without ambient light. And the viewing angle of the ToF sensor is about 27 degrees, and can be set narrower through programming.
