Technical problem to be solved in the utility model is realized using following technical scheme：
A kind of Doppler for door and window intrusion detection and vibrations dual technology detector, including main control unit and and master control
Main probe unit, aided detection unit, alarm unit, alarm unit, communication unit and the DC power supply unit of unit connection；Its
In, the main control unit be eight bit microprocessors, the main probe unit be doppler radar device, the aided detection list
Member is shock sensor, and the alarm unit is divided into doppler radar warning lamp and vibrations detecting alarming lamp, the alarm
Unit is voice guard, and the communication unit is RS485 buses, wireless WiFi and dry contact are switched, the direct current supply
Unit is direct current supply dropping equipment.
Further improvement lies in that the doppler radar device connects group by doppler antenna with operational amplifier
Into.
Further improvement lies in that shock sensor peripheral circuit with operational amplifier forms.
Further improvement lies in that the doppler radar warning lamp and vibrations detecting alarming lamp are by red, green, blue three
Color LED light emitting diodes form.
Further improvement lies in that the voice guard is made of triode and buzzer.
Further improvement lies in that the RS485 buses communicate IC by MAX485 and peripheral circuit forms, the wireless WiFi
It is made of communication module, the dry contact switch is made of relay.
Further improvement lies in that the direct current supply dropping equipment is made of linear voltage decreasing IC and filter circuit.
The beneficial effects of the utility model are：
1) there are double mirror detecting functions：Doppler radar device detects closely personnel's movement, and shock sensor can
To detect door and window vibrations, make to detect the situation for judging to effectively prevent reporting by mistake and fail to report twice；
2) there is front end warning and warning function：When doppler radar device detects closely personnel's movement, radar
Detecting alarming lamp flickers；When further triggering shock sensor detects door and window vibrations, sound, light crossing-signal start simultaneously, simultaneously
Communication unit sends alarm signal to host so as to fulfill effective preventive effect.
Description of the drawings
Fig. 1 is the systematic schematic diagram of the utility model.
Specific embodiment
In order to which the technical means, creative features, achievable purpose and effectiveness for realizing the utility model are easy to understand, under
