Abstract

The invention discloses an infrared signal amplification stage location coding circuit. The infrared signal amplification stage location coding circuit comprises an infrared induction and signal amplifying circuit, an infrared signal coding circuit and a power source circuit. The power source circuit provides 5V power source for the infrared induction and signal amplifying circuit and provides 12V power source for the infrared signal coding circuit and an infrared signal transmitting circuit. An infrared signal is induced by the infrared induction and signal amplifying circuit and is transmitted to the infrared signal coding circuit after amplification. The amplified infrared signal is received by the infrared signal coding circuit, converted into a location signal through an internal coder, and output. The infrared signal amplification stage location coding circuit provides the stable location signal so that external interference and unnecessary economic losses are avoided.

Description

technical field [0001] The invention relates to a position encoding circuit, in particular to an infrared signal amplification stage position encoding circuit. Background technique [0002] An alarm is an electronic product that reminds or warns people to take certain actions in the form of sound, light, air pressure, etc. in order to prevent or prevent the consequences of an event. Alarms are initially divided into mechanical alarms and electronic alarms. Along with the advancement of science and technology, the most used in the prior art is the infrared alarm, and the infrared alarm consists of an alarm host and an infrared detector to form an alarm system. Once an intrusion is detected, the infrared alarm immediately wirelessly transmits the position signal to the alarm host. After the host receives the position signal, it will issue an alarm and other functions. [0003] In the process of realizing the present invention, the inventor finds that at least the following d...
