Description
Technical field
The present invention relates to video safety precaution field, particularly the monitoring remote video field.
Background technology
The video monitoring technical development so far, the whole network digital video monitoring epoch have been entered, compare with traditional simulation monitoring, the digital information antijamming capability is strong, be not subject to the influence of transmission line signals decay, view data directly enters network through network video server, compression, transmission, storage and broadcast based on digital video, rely on powerful platform software to implement management, but existing monitoring software mostly need 24 hours manually on duty, even have intelligent alarm function, its price is also relatively more expensive, the warning rate of false alarm is also very high.
Summary of the invention
Deficiency at above monitoring technique, the purpose of this invention is to provide a kind of network video monitor and control system based on virtual instrument, realization integrates automatic monitoring, warning automatically, video recording, remote monitoring and unattended monitoring, and reduces use cost when reducing the warning rate of false alarm.
For achieving the above object, the technical solution used in the present invention is: based on the network video monitor and control system of virtual instrument, comprise camera 1, multi-channel video video tape recorder 2, data collecting card 3, server computer 4 and PC client computer 5, camera 1 is connected with multi-channel video video tape recorder 2, the input of data collecting card 3 is connected with multi-channel video video tape recorder 2, output is connected with server computer 4, server computer 4 links by network and PC client computer 5, in server computer 4 and the PC client computer 5 digital video monitoring software is housed, it is characterized in that: described digital video monitoring software cycles is moved following image processing main program: (a) acquisition of image data; (b) view data is published to network by server; (c) view data is converted to picture; (d) picture is play the demonstration real-time monitoring images continuously; (e) the intelligent alarm subprogram is handled picture, determines whether to report to the police, and does not then return (a) if do not report to the police, and then gives the alarm and display alarm information and carry out next step if report to the police; (f) warning message is published to network by server.
The flow process of described intelligent alarm subprogram is:
The first step: picture is converted to gray-scale map;
Second step: whether the inspection remote administrator is logined, if the local setting of reporting to the police is then obtained in login, then obtains the remote alarms setting if logined;
The 3rd step: according to warning set handling gray-scale map;
The 4th step: report to the police or do not report to the police according to result is definite, then do not return the first step, also return the first step again after the display alarm information if report to the police then to give the alarm to server computer if do not report to the police.
The method of described processing gray-scale map is: set the amplitude of variation of threshold values, the pixel value of pixel value, amplitude of variation that sensitivity is counted and the amplitude of variation of sensitive line number; Detect the pixel value on the sensitive line, if the absolute value of the pixel value on the sensitive line and the difference of threshold values is more than or equal to the amplitude of variation of pixel value, then confirm to have a sensitive spot, when sensitivity is counted the amplitude of variation that the difference of counting with the sensitivity of standard picture gray-scale map counts more than or equal to sensitivity, confirm to have abnormal conditions to take place; When the number of the sensitive line that produces sensitive spot during more than or equal to the amplitude of variation of sensitive line number, also confirming has abnormal conditions to take place.。
The flow process of the network service end main program of described digital video monitoring software is:
The first step: receive view data and warning message;
Second step: wait for that client connects;
The 3rd step: send view data and warning message to client;
The 4th step: judge whether remote administrator is logined, as logining, the remote alarms configuration information is write during server is provided with.As not landing, carry out next step;
The 5th step: judge whether the client connection is interrupted,, returned for second step,, returned for the 3rd step as not interrupting as interrupting.
