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

The invention relates to the technical field of security and protection, and provides a wireless remote-control infrared warning device. The wireless remote-control infrared warning device comprises a signal emitting terminal, a signal receiving terminal and an infrared warning terminal. The infrared warming terminal comprises a phase inverter CC4069, infrared receiving tubes VR1-VR5, infrared emitting tubes VD1-VD4 and a single chip microcomputer. Pins 1A-4A of the phase inverter CC4069 are sequentially connected with the infrared emitting tubes VD1-VD4 respectively. Pins 1Y-6Y of the phase inverter CC4069 are sequentially connected with pins P1.0-P1.5 of the single chip microcomputer respectively. Pins P0.0-P0.3 of the single chip microcomputer are sequentially connected with the infrared receiving tubes VR1-VR5 respectively. A pin P2.0 of the single chip microcomputer is connected with a resistor R3 connected with an audion Q1. The resistor R3 is connected with a base electrode of the audion Q1. An emitting electrode of the audion Q1 is connected with one end of a loudspeaker, and the other end of the loudspeaker is grounded. A collector electrode of the audion Q1 is connected with a positive electrode of a power source. A reset device of the single chip microcomputer is connected with a reset circuit. The wireless remote-control infrared warning device is good in interchangeability, high in response speed and interference resistance, simple in peripheral circuit, capable of directly performing infrared emission through the emitting module and small in size.
