Embodiment Construction

[0030] figure 1 In the shown embodiment, the anti-anesthetic theft device includes an infrared pyroelectric sensor 1, a Fresnel lens 2, an anesthetic gas sensor 3, a miniature DV9, an exhaust fan 5, an alarm buzzer 10, a red LED 11, detection and control Circuit 8 and other parts.

[0031] After the power socket 12 of this alarm is inserted into the civil electricity of 220V, the alarm can work. When the anesthetic gas sensor 3 is surrounded by an anesthetic gas atmosphere, the resistance value of the gas sensitive film of the anesthetic gas sensor decreases, and the detection and control circuit 8 will turn on the exhaust fan 5 and turn on the alarm buzzer 10 and the red LED 11 simultaneously.

[0032] When a moving human body passes through the detection range, the human body will sequentially enter a certain field of view of the Fresnel lens 2, and then walk out of this field of view, repeating many times, and the infrared pyroelectric sensor 1 will detect the moving human...

Abstract

The device comprises infrared pyroelectric sensor, fresnel lens, minitype DV (or telephone), exhaust fan, sensor of narcotic poison gas, detection and control circuit. Alarming device composed of infrared pyroelectric sensor and sensor of narcotic poison gas through wire connected to the detection and control circuit is an effective device for keeping watch theft entering to room by using narcotic poison gas. Sensors of narcotic poison gas are distributed multiple places inside room. When gas occurs, exhaust fan starts up to remove gas, meanwhile audible and visual alarm reminds host or warehouseman. If criminal thrusts oneself into room, the minitype DV starts up to record happening things and dials alarming phone. The infrared pyroelectric sensor and sensor of narcotic poison gas are plug and play device for detection and control circuit, and the sensors are possible to extend to be used in wireless transmission module for signal connection.

Description

technical field [0001] The invention relates to the field of anti-crime instruments and meters in which bad guys release narcotic poison gas to anesthetize family residents and warehouse keepers, and then enter and rob. Background technique [0002] In view of the fact that certain criminals in the society use anesthesia poisonous gas to fascinate the owner and then rob the house. In recent years, the prior art "modular automatic or remote control alarm system" (CN1283838A) and "modular Assembled automatic remote control alarm system" (Patent No.: 99113142.8, Publication No.: CN1283838A) has the functions of human body recognition, automatic dialing, camera, and door control, and plays an alarm role. No specific measures were taken. [0003] "Multifunctional safety alarm lamp" (patent number: 99231440.3) and "multifunctional lamp" (patent number: 02229965.3) have infrared pyroelectric sensors and gas alarms. Narcotic poison gas anesthetizes family residents and warehouse k...
