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 present invention relates to the field of intelligent control technology. In particular, the present invention relates to a virtual key and multi-zone protection method and device for automatic door control. Background technique [0002] The use of automatic doors in buildings can be traced back to the late 1920s, when automatic doors began to appear in supermarkets in the United States. Since then, automatic door technology has continued to develop. Hydraulic, air, and electric automatic doors have been widely introduced to the global market, and more and more new buildings have begun to use them at the front entrance. In our country, with the continuous advancement of urbanization, the application of automatic door technology has become more and more widespread. [0003] In the field of automatic doors, in order to detect people entering and exiting so as to control the automatic door to perform corresponding actions, infrared or laser sensors a...

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
