Problems solved by technology
[0004] The traditional window detection method is often based on the civil air defense mode. The staff hold the telescope to search one by one or manually check the video through the imaging device. Since the method based on civil defense will have human factors, such as human eye fatigue, etc., the false alarm rate is high. Detection The accuracy of the results is poor, and this traditional window detection method is time-consuming and laborious, and it is difficult to meet the needs of related work
[0005] Therefore, there is a need in the prior art for a solution that can solve the problem of poor accuracy of detection results due to the high rate of missed detection in traditional window detection methods

Embodiment Construction
[0026] Exemplary embodiments of the present invention will be described in detail below with reference to the accompanying drawings. The description of the exemplary embodiments is for the purpose of illustration only, and in no way limits the invention and its application or usage.
[0027] see figure 1 , according to the present invention, the photodetection device for detecting the switch state of windows includes a front-end photodetection unit, a back-end data processing unit 104 and a power supply 105 . The front-end photodetection unit detects the switch state of the window and forms a video signal, and then transmits the video signal to the back-end data processing unit; the back-end data processing unit receives the video signal transmitted by the front-end photodetection unit and detects the window switch state The back-end data processing unit can also control the working status of the pan / tilt.
[0028] The following is attached Figure 1-4 The photoelectric det...

The invention relates to a photoelectric detection device for detecting the opening-closing state of a window. The photoelectric detection device comprises a front-end photoelectric detection unit, a rear-end data processing unit and a power supply, wherein the front-end photoelectric detection unit comprises a sensor enclosure, a cradle head and a support. According to the photoelectric detection device for detecting the opening-closing state of the window, the opening-closing state of the window can be detected in real time, detection results are good in accuracy and stability, and the photoelectric detection device is convenient to transport and install.
Description
technical field [0001] The invention relates to the technical field of video monitoring, in particular to a photoelectric detection device for detecting the switch state of windows. Background technique [0002] The technical background related to the present invention will be described below, but these descriptions do not necessarily constitute the prior art of the present invention. [0003] In major security operations, in order to prevent snipers from attacking the roads and streets that key tasks pass through the windows or prevent residents from throwing objects through the windows, it is particularly important to detect the switch status and switch action of the windows. In addition, in order to prevent the windows of prisons, museums and other places from being damaged by thieves, it is necessary to monitor the opening and closing status of the windows. [0004] The traditional window detection method is often based on the civil air defense mode. The staff hold the ...
