Termite detection device and method based on photoelectric induction technology

Abstract

The invention provides a termite detection device and method based on a photoelectric induction technology, a detection box body is internally provided with a termite bridge and a termite bridge cover plate, the termite bridge and the termite bridge cover plate are spliced in the detection box body to form a detection chamber, the bottom surface of the termite bridge is provided with a plurality of through holes for termites to enter or leave the detection chamber, and the termite bridge cover plate is hermetically connected with the termite bridge. The termite bridge cover plate is made of a transparent material, the termite guiding assembly extends in the length direction of the termite detection device and is used for being buried in a to-be-detected area to attract termites to gnaw, a plurality of guiding channels are formed in the termite guiding assembly, and top openings of the guiding channels are sequentially communicated with a plurality of through holes in the bottom face of the termite bridge; the photoelectric detection assembly is used for detecting intensity change data of light which can transmit the termite bridge cover plate in the detection chamber after termite activity, and calculating termite activity intensity data based on the light intensity change data. According to the invention, the termite activity can be automatically and accurately detected based on the photoelectric sensing technology.
