Abstract
The utility model provides an infrared microwave detector comprising a shell, infrared probes, and microwave probes. The shell is internally provided with a PCB which is provided with a control circuit. There are two infrared probes which are arranged on the shell and coupled with the control circuit. The microwave probes are arranged on the shell and positioned between the two infrared probes. The two microwave probes are coupled with the control circuit. The control circuit comprises an A/D conversion circuit, an amplification circuit, an MCU and a power supply which are mutually coupled. According to the infrared microwave detector, detection is performed by adopting a mode of complementation of two infrared sensing and one microwave sensing so that false alarm and missed alarm can be effectively prevented.
Description
Technical field
The utility model relates to a kind of induction installation, particularly a kind of infrared microwave detector.
Background technology
Conventional detector adopts monotechnics conventionally, can not judge accurately intrusion object, wrong report often occurs and fail to report.Adopt the infrared eye of monotechnics disturbed by various thermals source, sunlight source.Infrared penetration power is poor, and the infrared radiation of human body is easily blocked, and is difficult for being detected device and receives.Be subject to the interference of radio-frequency radiation.When environment temperature and human body temperature approach, detection and sensitivity obviously decline, and sometimes cause malfunctioning in short-term.Adopt microwave that the microwave detector of monotechnics sends to have a penetrability to nonmetal, the vehicle travelling on the people of the outer walking of wall or road etc. all may cause false alarm.
Utility model content
The purpose of this utility model is to provide a kind of and effectively prevents that mistake is alert, the infrared microwave detector of false dismissal.
For solving the problems of the technologies described above, the utility model infrared microwave detector, comprising: housing, in described housing, be provided with pcb board, and on described pcb board, be provided with control circuit; Infrared probe, the quantity of described infrared probe is two, and two described infrared probes are arranged on described housing, and two described infrared probes and described control circuit are of coupled connections; Microwave probe, described microwave probe is arranged on described housing, and described microwave probe is arranged between two described infrared probes, and two described microwave probes and described control circuit are of coupled connections.
Described control circuit comprises the A/D change-over circuit, amplifying circuit, MCU and the power supply that intercouple and connect.
The utility model infrared microwave detector adopts the mode of two infrared sensings and the complementation of a microwave sensing to detect, and effectively prevents that mistake is alert, false dismissal.Microwave and infrared two kinds of complementary modes are surveyed, and analyze through fuzzy logic is digital, get rid of the interference that all conventional detectors cannot overcome, and only human motion are made to warning, stop wrong report and fail to report.Just can produce alerting signal owing to only having in the time that passive infrared technology and microwave technology detect invasion simultaneously, thereby the improvement of the low rate of false alarm aspect of detector is achieved.
