Automatic door system based on radar sensor

Abstract

The invention relates to an automatic door system based on a radar sensor. The control on an automatic door is realized by the automatic door system by utilizing radar as a motion sensing sensor. The automatic door system comprises the radar sensor and a controller; when people or other foreign matters enter into a detecting area of the radar sensor, a response signal is generated by the radar sensor and is transmitted to the controller, and the controller immediately drives a motor to open a door; four-level speed regulations, namely, high speed, middle speed, low speed and extruding speed, are adopted by the controller; the low speed is adopted during the process of door distance measurement; the high speed, the middle speed and the extruding speed are adopted during a normal running process; and the speeds are adjusted by an accurate potentiometer.

Description

technical field [0001] The invention belongs to the technical field of sensors, and in particular relates to an automatic door control system using radar as a motion perception sensor. Background technique [0002] At present, various restaurants, guesthouses and smart buildings have high requirements for doors, and most of the various automatic doors on the market are imported from abroad. Although the performance is stable, the price is high, ranging from tens of thousands to hundreds of thousands of yuan; The quality of various automatic doors is slightly inferior. Although the price is low, the reliability of the overall performance is not high, the functions are few and the repair rate is high. The core part of the automatic door system is the controller, which is very important to the operation of the system. However, the types of automatic door controllers in the market are single and there are few related studies. The newly developed automatic door controller based ...
