Microwave detector

Abstract

The invention discloses a microwave detector which is composed of a microwave transmitter and a microwave receiver, wherein a microwave transmitting antenna board and a microwave transmitting modulation control board are included inside the microwave transmitter; the microwave receiver comprises a microwave receiving antenna board, a data acquisition and analysis control circuit, a control key orswitch, an LCD (Liquid Crystal Display) screen and a signal output circuit. According to the microwave detector disclosed by the invention, the LCD screen is designed and mounted on the receiver of the microwave detector and is used for displaying main parameters and operating states of the microwave receiver, great convenience is brought to users for accurately and intuitively mastering various data of the microwave detector in real time in the product mounting, debugging and using processes, debugging of the microwave detector can be rapidly and accurately completed, the working efficiency is improved, and the problems that the traditional opposite-type microwave detector is difficult to debug because the operating data of the detector cannot be intuitively and accurately mastered or islow in efficiency due to inaccurate debugging, and that false alarm is easily produced due to inaccurate debugging can be effectively solved.

Description

technical field [0001] The invention relates to the technical field of microwave intrusion detectors, in particular to a microwave detector. Background technique [0002] Since the through-beam microwave detector can form an invisible protective wall between the microwave transmitter and the microwave receiver, when an object of a certain volume passes between the microwave transmitter and the microwave receiver, it meets the alarm conditions of the microwave detector , the microwave detector receiver outputs an alarm signal; because the microwave detector has a long protection distance, it is not easy to be affected by wind, frost, rain, snow, fog and other environmental influences to generate false alarms, and its work stability is good, so it is currently widely used in prisons, detention centers, petrochemical industries, etc. , nuclear power plants, military restricted areas and other important protective places, as the main perimeter intrusion detectors for these imp...

AI Technical Summary

Problems solved by technology

At present, the through-beam microwave detectors on the market do not have the detector working status and technical parameter display circuit. During the installation, debugging and use of the detector, the user can only judge the detector vaguely according to the method provided by the detector manufacturer. The working state of the detector cannot be accurately debugged to make the detector work in the best state, resulting in false alarms during the use of the detector, requiring engineers and technicians to calibrate and fine-tune multiple times to achieve a stable working state
