Technical Field

The present application relates to the field of intrusion detection technology, and more particularly, to an intelligent microwave detection system and method for intrusion detection.

Background

Existing intrusion detection systems typically employ Pyroelectric Infrared (PIR) detectors. Such Pyroelectric Infrared (PIR) detectors operate with infrared radiation of 10 μm wavelength emitted from the human body at 37 ℃. For verification of the detection result, a Pyroelectric Infrared (PIR) detector is also commonly used in combination with a camera (as shown in fig. 1, fig. 1(a) is CAMIR series by honeywell, inc, and fig. 1(b) is IMV60 by RSI, inc). When the PIR detector detects an intrusion event, the detector triggers the camera to shoot so as to carry out further verification on the intrusion event. However, such intrusion detectors are sometimes unreliable. Such as false positives, which may occur when an intruder has an abnormal body temperature or when the intruder is shielded by a foreign object, or such as white light or hot air interference near the detector. In addition, some of the existing intrusion detection systems employ microwave detectors in combination with a camera. However, these microwave detectors are conventional microwave detectors that only monitor a general area and do not eliminate the similar problems of false negative and false positive as PIR detectors. Furthermore, since the detection of an intrusion event may trigger the camera to take a picture or a short video, false positives by the detector may also cause the camera to take many unwanted pictures, thereby occupying a large storage space and creating unnecessary waste.

It is therefore a long felt desire to provide an intrusion detection system and method that is easy to use, has a low cost, and can effectively reduce the problems of false negative and false positive.

With the development of the intelligent microwave technology, the intelligent microwave detector can not only detect the position, distance, speed and direction of an object, but also accurately detect a specific detection area designated by a user by setting a detection mode. However, existing intrusion detection systems do not incorporate this intelligent microwave technology. Therefore, the present invention is directed to combine the intelligent microwave detection technology with the remote communication technology, and provides an intelligent microwave detection system and method capable of being set through the remote communication system, so as to realize the leap development of the intrusion detection technology.

Detailed Description

The following further describes embodiments of the present invention with reference to the accompanying drawings.

According to one embodiment of the present invention, the intelligent microwave detection system includes an intelligent microwave detector that can communicate with a user terminal (e.g., a notebook, a cell phone, a tablet computer, etc.) through a telecommunication system. The telecommunication system includes, but is not limited to, for example, a mobile communication network (e.g., GMS), the internet, and the internet of things (IOT), and various wired remote networks. Preferably, the telecommunication system comprises a cloud server. The intelligent microwave detector can emit microwave beams with different directivities according to different modes, so that precise detection can be performed for a specific area designated by a user. In addition, the intelligent microwave detector can also detect the position, distance, speed and direction information of an object, so that the intelligent microwave detector can be set according to actual requirements.

When an intruder enters the monitoring range of the detector, the detector will trigger the camera to take a picture. FIG. 2 is an intrusion event captured by a camera according to one embodiment of the invention. As shown in fig. 2, compared to the conventional microwave detector, the intelligent microwave detector can emit downward microwave beams according to the area that the user needs to monitor, forming an approximately fan-shaped monitoring area, while there is only a small blind area at the lower part of the detector. Fig. 2 is merely an example, the actual monitored area may be any ground area or space, and the user may set the detection mode of the detector accordingly, so that microwave beams directed in various directions may be generated as desired, covering any shape of area.

Further, photos or videos, such as those taken in fig. 2, may also be transmitted to the user via the telecommunication system for confirmation by the user. The user can also set a photographing mode of the camera through the telecommunication system.

Fig. 3 shows a functional block diagram for an intelligent microwave detection system according to one embodiment of the present invention. By way of example and not limitation, the functional block diagram of fig. 3 includes a smart microwave detector module 210, a camera module 220, a memory module 230, a Main Processing Unit (MPU) module 240 communicatively coupled to the aforementioned modules, and a communication module 250 communicatively coupled to the Main Processing Unit (MPU) module 240. The camera module 220 is triggered by the microwave detector module 210 through the MPU module 240 and captures an intrusion event; the memory module 230 may be used to store and buffer pictures and/or video taken; the Main Processing Unit (MPU) module 240 processes a detection signal for the detector module 210, controls the camera module 220, and the communication module 250; and the communication module 250 may perform bidirectional transmission of information by, for example, connecting to a cloud server, thereby enabling remote setting of a detection mode of the detector and a camera photographing mode. In addition, the functional block diagram of fig. 3 may further include a PIR detector, thereby further enhancing the detection accuracy and reliability of the microwave intelligent detection system according to the present invention.

By way of example and not limitation, the smart microwave detector module 210 includes Monolithic Microwave Integrated Circuits (MMICs) and peripheral circuits as core components to enable different detection modes and smart detection of such things as position, distance, speed and direction information of objects. The peripheral circuits include two antennas (one or more may be used as required to implement beamforming and transceiving functions of microwave signals) at the front end of the MMIC, amplifiers and filters behind the MMIC, and a modulation/waveform generator communicatively connected to the MMIC, etc.

Fig. 4 shows a detailed block diagram of the core components (i.e., MMIC) of the microwave detector module 210 in fig. 3. By way of example and not limitation, the MMIC is a highly integrated BGT24MTR 1124 GHz transceiver. As can be seen from fig. 4, the MMIC includes components such as a temperature sensor, a power sensor, and a buffer, thereby implementing a transceiving function for microwave signals.

Fig. 5 shows a flow diagram of an intelligent microwave detection method for intrusion detection according to one embodiment of the invention. As can be seen in fig. 5, after the intelligent microwave detection system is started, the system is initialized first. If the intelligent microwave detector cannot complete the self-test, an error warning is issued, thereby notifying the user of the error. Otherwise the user can set the detection mode of the microwave detector through the telecommunication system as desired. If the set mode does not meet the requirements, the user can reset the setting, otherwise the detector will be in the monitoring state (if necessary, the user can check the detection mode again). In the intrusion detection process of the microwave detector, a user can reset the detection mode at any time according to the requirement. If the detector detects an intrusion event, the camera will be triggered immediately to take a picture, a picture and/or video will be captured continuously by the camera for a certain time period for the intrusion event and the taken picture and/or video will be sent to the user for confirmation by the user via the telecommunication system. Further, the user can also set a shooting mode of the camera through the telecommunication system.

In summary, compared with the conventional technology, the intelligent microwave detection system and method of the present invention have the advantages of cost saving, convenient use, and reduction of false alarm and missing report, and thus become the main development direction in the field of intrusion detection technology. Besides, the intelligent microwave detection system and the method can be widely applied to industrial production environment monitoring, public place access monitoring, home security and the like.
