The utility model is suitable for theft protection on various occasions.
Description
Technical field
The utility model relates to the electronic anti-theft security system, is specifically related to a kind ofly in conjunction with microwave induced Detection Techniques and passive infrared induction Detection Techniques mobile intrusion object be carried out the mobile intrusion detector of detection alarm.
Background technology
The electronic anti-theft security system is as individual or reliable, the most effective guard method of public property, and at home and abroad developed country has obtained using widely.Nearly all government department, financial department and commercial unit all install and use the electronic anti-theft security system, and the domestic consumer above 80% also selects to use the electronic anti-theft security system.Practical application effect shows, installs and uses the electronic anti-theft security system and can effectively reduce generation into cases such as room theft, robberies, ensures the person and property safety.In China, only install and use at present, and personal user's utilization rate is very low on part financial sector, confidential departments of government, historical relic unit and other places.
Two technology move intrusion detector and are mainly used in the electronic anti-theft security system, be in the burglary-resisting system most important before end detector, it can the detecting intrusion person and sends invaded signal to control system, and is therefore also very high to the performance requirement of detector.The detector of monotechnics means, its reliability is relatively poor, can only be applied in less demanding occasion, and is just inapplicable in commercial situations or other high request occasion.

Description of drawings
Fig. 1 is that the utility model moves the intrusion detector theory diagram;
Fig. 2 is that the utility model moves invasion detector circuit figure.
Embodiment
As shown in Figure 1, the utility model microwave treatment unit of moving intrusion detector includes power supply, radar antenna inductive component, low-pass filter, amplifying circuit, wave detector, voltage comparator and output buffer.Described radar antenna inductive component is that microwave high-frequency oscillator, frequency mixer, transmitting antenna and receiving antenna are arranged.Transmitting antenna is the detection letter Fs of 10.5GHz with pulse mode directional transmissions frequency at intermittence, and receiving antenna receives the feedback signal Fo that returns from mobile object.Frequency mixer carries out Frequency mixing processing to Fs and Fo signal, obtains reacting the intermediate-freuqncy signal IF in the moving target.When target body was normally walked about, promptly speed was 5km/h, and mixing output is about 49Hz; When target vehicle moved, promptly speed was 50km/h, and its mixing output is about 488Hz.This intermediate-freuqncy signal IF is input to low-pass filter, and this low-pass filter is input to amplifying circuit with the signal that filters out and amplifies, and enters voltage comparator by wave detector again, and comparative result is input to microprocessor control by output buffer.Because frequency height, the directive property of microwave are good, antijamming capability is strong; it is low to be compared to general frequency of ultrasonic commonly used, and directive property is too broad, poor anti jamming capability; easily detect object outside the protection zone and cause that the characteristics of wrong report, microwave are applicable to that more intrusion detector uses.
The passive infrared processing unit that the utility model moves intrusion detector includes Passive Infrared Sensor assembly, bandpass filter, amplifying circuit, voltage comparator and output buffer.Described Passive Infrared Sensor assembly is made up of electric Passive Infrared Sensor and Fei Nier optical lens, luxuriant and rich with fragrance Neil optical lens is divided into a lot of sector regions with investigative range system, when moving the invasion human body by the sector region in the investigative range, this Passive Infrared Sensor can induce the infrared heat energy of human body radiation, and with its input tape bandpass filter, be transformed into the electric signal that the invasion human body target is moved in reaction by bandpass filter, this electric signal enters amplifying circuit and is amplified into voltage comparator.Comparative result then is input in the microprocessor by output buffer.
The microprocessor that the utility model moves intrusion detector not only links to each other with the passive infrared processing unit with the microwave treatment unit, also links to each other with a relay output circuit with a crystal oscillating circuit, a LED output circuit.This crystal oscillating circuit is a clock circuit of microprocessor, and this LED output circuit is to link to each other with a light-emitting diode display, and this relay output circuit then is to link to each other with warning device.
The utility model moves the algorithm that the microprocessor of intrusion detector uses a kind of ratio to discern, and by microprocessor real-time dynamic monitoring microwave/infrared number of times that is triggered, calculates to determine whether to send warning information in the ratio of optimum.
As shown in Figure 2, microwave treatment unit 1 links to each other with microprocessor 3 by pin 13, and passive infrared processing unit 2 links to each other with microprocessor 3 by pin 14.When wherein a kind of Detection Techniques break down, the 13rd or 14 pin input that also is microprocessor 3 is unusual, the program of microprocessor 3 can detect unusual pin position automatically, the input that microprocessor 3 shieldings are broken down, start single technology detection mode simultaneously, only detect the signal of another kind of Detection Techniques, thereby finish two technology automatic switching functions.
