Problems solved by technology
However, the traditional anti-theft detection system needs a signal line between each detector and the host to transmit the alarm signal of each detector. When the number of detectors is large, the number of signal lines connected to the host increases accordingly. , may be dozens or even hundreds, not only inconvenient for installation and construction, but also increases the cost and brings difficulties to daily maintenance

The invention discloses an infrared detection device easy and convenient to wire.The infrared detection device simple and convenient in wiring comprises a power source, a sensing unit, an amplification unit, a comparison unit, an opposition unit, a storage unit, a control door unit, an oscillating unit, a counting unit, a pulse quantity setting unit, a control unit and an output unit.By means of the infrared detection device easy and convenient to wire, invasion can be detected in time and accurately, the invasion position can be positioned in time and accurately, the device has the advantages of being high in sensitivity and stable and reliable in work, meanwhile, when the device is applied to an antitheft detection system, alarm signals of all detectors in the system can be transmitted to a host through a shaped signal line, the circuit structure is greatly simplified, and installation and maintenance work load is lowered.
Description
technical field [0001] The invention relates to the technical field of electronic circuits, in particular to an infrared detection device with simple wiring. Background technique [0002] With the continuous improvement of living standards since China's reform and opening up, people's requirements for personal and property safety are also increasing. The anti-theft detection system is used more and more widely as an important facility to prevent accidents such as robbery and theft. The currently commonly used anti-theft detection system deploys several infrared detection devices with simple wiring in the monitoring area, which can detect intrusions in the monitoring area, send an alarm to the host when an intrusion occurs, and lock the intrusion location. However, the traditional anti-theft detection system needs a signal line between each detector and the host to transmit the alarm signal of each detector. When the number of detectors is large, the number of signal lines co...
