Virtual key and multi-area protection method and device for automatic door control

Abstract

The invention discloses a virtual key and multi-area protection method and device for automatic door control. The virtual key and multi-area protection method comprises the steps that relevant parameters of a virtual key area of an automatic door are set; relevant parameters of protecting areas of the automatic door are set; the virtual key area is detected, and if an object conforming to the relevant parameters enters the virtual key area, door opening operation is triggered; and the protecting areas are detected, and if objects conforming to the relevant parameters enter the protecting areasin the door action process, corresponding protecting protection is triggered. The invention discloses the virtual key and multi-area protection device used for realizing the method as well.

Description

technical field [0001] The invention relates to the technical field of intelligent control, in particular, the invention relates to a method and device for virtual keys and multi-region protection for automatic door control. Background technique [0002] The use of automatic doors on buildings can be traced back to the late 1920s, and the application of automatic doors began to appear in supermarkets in the United States. Since then, automatic door technology has been continuously developed, and hydraulic, air, and electric automatic doors have been widely promoted to the global market one after another, and more and more front doors of new buildings have also begun to be used. In our country, with the continuous advancement of the urbanization process, the application of automatic door technology has become more and more extensive. [0003] In the field of automatic doors, in order to realize the detection of people entering and leaving in order to control the automatic do...

Problems solved by technology

[0007] First of all, the use of multiple sensors has caused problems such as high cost, inconvenient installation, complex signal processing, and increased possible failure points; second, once the installation is completed, the height of the infrared transmitter and receiver is fixed, so only It is not easy to configure flexibly because it can detect objects at this horizontal position; third, this type of configuration can only detect whether there is a block between the infrared emitter and the infrared receiver, but cannot know the size and shape information of the object causing the block So as to make more accurate and intelligent judgments; Fourth, there is only one protected area for the above solution (see figure 2 In area C), it cannot act on such as figure 2 Area D on both sides of the sliding door; in practical applications, these two areas often need to be treated separately, and the protection logic and the protection action performed are different
