Beneficial effect：Compared with prior art, its remarkable advantage is the present invention：1st, the system uses wireless video transmission side
Formula, the line transmission of complexity and the safety problem due to aging circuit appearance can be avoided；2nd, the system is due to setting alarm rule
Then, there is automated intelligent analysis ability, just start to store video after being triggered, difference need to all be stored with conventional monitoring systems and regarded
Frequency evidence, it can greatly save memory space.
Brief description of the drawings
Fig. 1 is the structured flowchart of the present invention；
Fig. 2 is the structured flowchart of monitoring center module of the present invention.
Embodiment
Such as Fig. 1, underground pipe gallery wireless video monitoring system of the present invention, including：Data acquisition module, data processing
Module, data transmission module and monitoring center module.The system also provides client and checks video capability, client can by regarding
The monitor video that frequency monitoring software is checked in the computer memory module.
Data acquisition module, underground pipe gallery key position is monitored by front network video camera, recorded a video, by video
Data acquisition stores.
Data processing module, for being pre-processed to described video data, including：
Step 1, video lens segmentation
Video lens segmentation is carried out using the method based on histogram, it deal with it is simple and convenient, and for most
Number video, can reach relatively good effect.Based on the method for histogram by gray scale, brightness or the color of each pixel of consecutive frame
N number of grade is divided into, then makes histogram for each grade statistical pixel number and compares.This method counted overall gray scale or
