Photoelectric Detector In The Border Control Application

The traditional frontier detection is mostly carried out by the artificial way, however, the backward way should be changed at the right moment as the digitalization and multimedia development in the field of military.The thesis analyses the present situation of the frontier detection and the problems according to the requirement of strengthening control, designs the scheme of control system for instance of control aims of frontier company, besides analyses the function of frontier detection system, introduces the composition and principle of all the parts of frontier control system, it has some consult value in the construct of detection system in our frontier force.The thesis briefs the principle of photoelectric sounder in the detection system, such as inspecting video camera and photoelectric warning sounder, analyses imagery factor of video camera in the light of bonder condition in theory, calculators and analyses the limits of the detecting angle of vision for the detecting distance of the video camera, the matching between the lens and video camera and the choices of the focal distance in the different detecting aims and working environment, and also designs the installing method of the video camera.The thesis raises that we can enhance the effect of detection in the method of combining detecting with warning for the emphasis aims of warning in border district, introduces the working principle, working characteristic and working condition of the active infrared warning detecting sounder, passive infrared warning detecting sounder and fibre warning detecting sounder, as well as puts forward some measures to prevent warning by mistake, designs the installing method of the warning detecting sounder. The research achievement of this thesis provides useful reference for the construction of detecting instrument in the frontier force.
