Anti-interference microwave induction lamp and method for resisting environment microwave interference

Abstract

The invention discloses an anti-interference microwave induction lamp and a method for resisting environment microwave interference. The anti-interference microwave induction lamp comprises a lamp, ahigh-frequency transceiving module, a signal amplifier module, a signal output module and a control module, the signal amplifier module is in communication connection with the high-frequency transceiving module, the signal output module is in communication connection with the lamp, the control module is in communication connection with the signal amplifier module and the signal output module, thehigh-frequency transceiving module radiates frequency signals to ambient environments, the frequency signals meet a moving object, then are reflected to the high-frequency transceiving module and generate weak alternating-current detection signals, the detected signals are amplified and transmitted into the control module, the control module decodes the detected signals by a sampling and comparingmode and detects whether fluctuation generated by the detected signals meets a preset range or not, the control module transmits a lightening instruction to the signal output module if the fluctuation meets the preset range, and the signal output module controls the lamp to be lightened according to the lightening instruction.

Description

technical field [0001] The invention relates to the field of outdoor induction lamps, and more specifically relates to an anti-interference microwave induction lamp and a method for anti-environmental microwave interference. Background technique [0002] As we all know, microwave is a short-wavelength, high-frequency electromagnetic wave, which is characterized by being sensitive to environmental changes within the range of action, so microwaves can be used to detect environmental changes. Microwave induction lamps are a common lamp that uses microwaves to detect human body signals to achieve automatic switching. Using the principle of microwave induction, the lamps are intelligent and are widely used in the lighting industry. [0003] However, the existing microwave induction lamps are easily disturbed by external environmental factors, and are only suitable for semi-outdoor environmental applications. Since the interference of harsh environments such as rain and snow is v...

[0003] However, the existing microwave induction lamps are easily disturbed by external environmental factors and are only suitable for semi-outdoor environmental applications

Since the interference of harsh environments such as rain and snow is very similar to the waveform of the human body movement signal collected by the microwave sensor, it is difficult to effectively distinguish

In harsh weather conditions such as rain and snow, existing microwave induction lamps are prone to self-excited interference, resulting in malfunction and energy waste
