Problems solved by technology
[0003] However, the aforementioned non-contact radar sensing technology is not conducive to direct analysis and conversion of signals simultaneously received on the receiver after the incident continuous wave is reflected by objects and the entire environment
All backscattered signals generated by reflection, when performing signal analysis, these noise signals caused by the environment will form interference, which will cause the sensed signal to be difficult to distinguish, so there are still limitations in use

Embodiment Construction
[0030] Please refer to figure 1 , which is a circuit block diagram of an intelligent monitoring system according to an embodiment of the present invention. exist figure 1 In the shown embodiment, the intelligent monitoring system includes a signal processing unit 100 , a camera unit 110 and a wireless signal processing unit 130 . Wherein, the signal processing unit 100 is electrically coupled to the camera unit 110 and the wireless signal processing unit 130 .
[0031] like figure 1 As shown, the photographing unit 110 is used for photographing the surrounding environment, so as to obtain images of the surrounding environment through photographing. In this embodiment, the shooting range of the photographing unit 110 may cover at least one object under test (here, two objects under test 150 and 160 ), and the captured image is transmitted from the photographing unit 110 to the signal processing unit 100 . The signal processing unit 100 receives the image from the photograph...

The invention discloses an intelligent monitoring system, an intelligent monitoring method and a photography device using the intelligent monitoring system. The intelligent monitoring method includes the following steps that: whether an object exists is confirmed; if the object exists, the movement phenomenon of the object is analyzed, so that reference signals can be generated; wireless signals are sent to the object, and returned reflected wireless signals which are generated after the wireless signals are reflected by the object; the reflected wireless signals are analyzed in an auxiliary manner with the reference signals, so that change detection signals corresponding to the change of the object can be obtained; and when the change detection signals exceed a preset standard, alarm signals are emitted. According to the intelligent monitoring system, the intelligent monitoring method and the photography device, optical photography technology, image processing technology and wireless sensing technology are integrated, and can support each other, and therefore, requirements for hardware equipment can be reduced, reaction speed can be increased, the probability of misjudgment can be reduced, and the accuracy of monitoring can be increased.
Description
technical field [0001] The invention relates to the technical field of intelligent monitoring, in particular to an intelligent monitoring system and method and a photographing device using the same. Background technique [0002] The current non-contact radar sensing technology is mainly based on the continuous wave Doppler radar sensing principle, which is generally divided into two practical methods: continuous wave Doppler radar direct conversion receiving method and phase-locked self-injection locking Signal sensing radar transceiver mode. The former uses the continuous radar wave as the detection wave source, and transmits the continuous wave to the object to be measured, because the continuous wave will form a backscatter signal after being reflected by the object, so the Doppler frequency of the backscatter signal is caused by the displacement change of the object Phase angle modulation, and then receive the backscattering signal generated by the reflection of the obj...
