Problems solved by technology

However, the existing access control electronic dog uses an infrared control system to control the opening and closing of the access control electronic dog. This control system has the problem of being prone to false start, which leads to the failure of the access control electronic dog to play a good role in welcoming guests. Thereby existing access control electronic dog can not satisfy people's demand

Abstract

The invention discloses a wave detection system for an access control electronic dog with stable performance, which is characterized in that it comprises an ultrasonic transmitting circuit and an ultrasonic receiving circuit connected with the ultrasonic transmitting circuit. The present invention is simple in structure and strong in practicability. The system generates a reference oscillation frequency through a time-base oscillation circuit, and the oscillation frequency exists between the ultrasonic sensor LS1 and the ultrasonic receiver LS2. The level of the oscillation frequency is increased, so that the detection system outputs a high level to drive the access control electronic dog to open, thereby ensuring that the electronic door of the access control does not turn on by mistake.

Description

technical field [0001] The invention relates to a detection system, in particular to a detection system for an access control electronic dog with stable performance. Background technique [0002] With the continuous development of science and technology, more and more electronic products have entered people's lives. Among them, the access control electronic dog is favored by people because it can be used as a guard or welcome. At present, most supermarkets and other stores use access control electronic dogs as welcome guests. This kind of access control electronic dogs used for welcoming guests in stores realizes the welcome function through ultrasonic detection systems. However, the existing access control electronic dog uses an infrared control system to control the opening and closing of the access control electronic dog. This control system has the problem of being prone to false start, which leads to the failure of the access control electronic dog to play a good role i...
