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

Abstract

The invention discloses a circuit applied to an anti-theft detector.The circuit applied to the anti-theft detector comprises a power source, a sensing unit, an amplifying unit, a comparing circuit, an inverting unit, a storage unit, a control door unit, an oscillating unit, a counting unit, a pulse number setting unit, a control unit and an output unit.The circuit applied to the anti-theft detector can accurately detect an invasion and position the invasion position in time, and has the advantages that sensitivity is high and working is stable and reliable; when the circuit is applied to an anti-theft detection system, alarm signals of all detectors in the system can be sent to a host machine through a common signal line, the circuit structure is greatly simplified, and the workload of installation and maintenance is reduced.

Description

technical field [0001] The invention relates to the technical field of electronic circuits, in particular to a circuit applied to an anti-theft detector. 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 widely used anti-theft detection system deploys several circuits applied to anti-theft detectors in the monitoring area, which can detect intrusion behaviors 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 conn...
