Remote control infrared transmitting circuit of infrared alarm

Abstract

The invention relates to the field of security technologies and provides a remote control infrared transmitting circuit of an infrared alarm. The remote control infrared transmitting circuit is characterized by comprising a transmitter, a receiver, and an infrared transmitting terminal. The transmitter is an RCM-1A transmitting module. The receiver comprises an RCM-1B receiving module, a decade count frequency divider digital integrated circuit, and a transistor switch VT circuit. A pin 2 of the RCM-1B receiving module is connected with a pin 15 of a CD4017 decade counter through a diode VD1. Pins 2, 7, 1, 6 and 11 of the CD4017 decade counter are all connected with a resistor R12 through diodes. The resistor R12 is connected with a base of a triode VT. The triode VT serves as a switch between the rear infrared transmitting end and a power source. The infrared transmitting end comprises a diode D5, an infrared diode D6, resistors R14-R17, a resistor R20, triodes VT6-VT8, and the power source VCC.

Description

technical field [0001] The invention relates to the field of security technology, and provides a remote control infrared emitting circuit of an infrared alarm. Background technique [0002] With the establishment of my country's market economy system and the development of science and technology, my country's security industry continues to advance, and the security market has become an emerging high-tech market with great potential that reflects the close integration of public security and technology defense. Development offers rare opportunities. And the domestic security industry is rapidly integrating with international standards. Our country has the largest security product market in the world, which is our greatest advantage. The security industry in developed countries in Europe and the United States has developed rapidly on the basis of the original, and its rapid growth can also be foreseen in other developing countries, such as Asia, Latin America, Eastern Europe, ...

Problems solved by technology

In the past anti-theft systems, technical measures such as pyroelectric and microwave were generally used to collect human body intrusion signals. These have good results when applied indoors. The proposed measures have a very high rate of false alarms in actual use, and sometimes even fail to work properly
