Abstract

The invention discloses a simple infrared safety protection electronic product detector comprising a direct-current power source, first to sixteenth resistors, an alarm signal lamp, first to fifth capacitors, first to sixth triodes, a first light-emitting diode, a second light-emitting diode, a first photosensitive transistor, a second photosensitive transistor, and an adjustable unijunction transistor. When an object blocks light of the first light-emitting diode light from being irradiated on the photosensitive transistors, the first photosensitive transistor is switched from a switched-on state to a switched-off state, and the second light-emitting diode and the second photosensitive transistor amplify power and transmit the power to the alarm device. Compared with the prior art, the simple infrared safety protection electronic product detector of the invention has the advantages of simple circuit structure, low cost, small size and easy carrying, is convenient to maintain and overhaul, and is easier to popularize and promote.

Description

technical field [0001] The invention relates to a security electronic product detection device, in particular to a simple infrared security electronic product detector. Background technique [0002] According to the interpretation of the current Chinese dictionary, the so-called safety means no danger, no infringement, and no accidents; the so-called precaution means precautions and precautions, and precautions refer to making preparations to deal with attacks or avoid being victimized, and precautions refer to prevention and protection . Based on the above explanations, is it possible to define safety precautions as follows: prepare and protect to deal with attacks or avoid victims, so that the protected objects are in a safe state where there is no danger, no infringement, and no accidents. It is obvious that safety is the purpose, and prevention is the means. To achieve or realize the purpose of safety through the means of prevention is the basic connotation of safety pr...
