Embodiment
As Fig. 1, a kind of network video monitor and control system, camera 1, multi-channel video video tape recorder 2, data collecting card 3, server computer 4 and PC client computer 5 are formed; 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, and the intelligent alarm video monitoring software with the Labview language compilation is housed in server computer 4 and the PC client computer 5.The camera 1 of native system can adopt infrared camera, can be provided with a plurality ofly according to actual needs, and data collecting card 3 can be the USB video frequency collection card, and what native system adopted is that resolution is 720 * 576 USB video frequency collection card.The intelligent alarm video monitoring software comprises image processing main program, network service end main program, customer service end main program, and the image processing main program contains the intelligent alarm subprogram.The workflow of this supervisory control system is as follows:
The view data at camera 1 acquisition monitoring scene; The view data that multi-channel video video tape recorder 2 is collected each camera collection; Data collecting card 3 carries out view data to import server computer 4 into after the analog-to-digital conversion; Intelligent alarm video monitoring software in the server computer 4 is handled view data.As shown in Figure 2, systemic circulation 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, if report to the police then display alarm information and give the alarm and carry out next step; (f) warning message is published to network by server.
As shown in Figure 3, the intelligent alarm subprogram at first is converted to gray-scale map with picture, checks then whether remote administrator is logined, and then obtains the remote alarms setting as if having logined, if the local setting of reporting to the police is then obtained in login.The content that is provided with of reporting to the police is: the emphasis alarm region is provided with, its method is: the gray-scale map of choosing the standard picture at monitoring scene under the secondary normal condition, sensitive line is set in relevant position at gray-scale map, the on-the-spot corresponding emphasis alarm region of monitoring is promptly represented in the position of sensitive line, sensitive line can set one or more according to actual needs, and representative is provided with one or more emphasis alarm regions.Warning sensitivity is provided with, and warning sensitivity is with two parametric representations, the one, the amplitude of variation that sensitivity is counted on the sensitive line, the 2nd, the amplitude of variation of sensitive line number.The implication of the amplitude of variation of amplitude of variation that sensitivity is counted and sensitive line number is as hereinafter explaining.
The intelligent alarm subprogram is according to warning set handling gray-scale map, processing method as shown in Figure 4: set the threshold values of pixel value in the gray-scale map, the amplitude of variation of pixel value, the amplitude of variation of amplitude of variation that sensitivity is counted and sensitive line number.Detect the pixel value on the sensitive line, if the absolute value of the difference of pixel value and threshold values is more than or equal to the amplitude of variation of pixel value, confirm that then there is a sensitive spot in this zone, 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.
When the intelligent alarm subprogram confirms to have abnormal conditions to take place, just give the alarm and with the mode display alarm information of prompting frame, warning message comprises time of fire alarming, place and warning reason etc. to server computer in the mode of playing back music and flashing indicator light.
Server computer is passed to PC client computer with warning message and view data by network by carrying out the network service end main program, and its flow process 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.
View data and warning message are transmitted through the network to the PC client computer, and the PC client computer is carried out networking client main program as shown in Figure 5:
The first step: the service end address is set, the Connection Service end;
Second step: image display pattern is set, and described image display pattern comprises that multichannel shows and single channel shows, promptly the user can select to check the monitoring image of all cameras shootings or the monitoring image that any one camera is taken;
The 3rd step: obtain view data and warning message;
The 4th step: view data is converted into picture and demonstration in real time;
The 5th step: display alarm information;
The 6th step: report to the police according to the type of alarm that the user selects.
Circulate and carry out the selection of user's login and type of alarm during above-mentioned 2-5 goes on foot, type of alarm comprises playing back music and flashing indicator light, and the user can select a kind of type of alarm, also can select two kinds of type of alarms simultaneously.
Native system also has recording function, and user's can select to report to the police when type of alarm is selected at the main interface of monitoring mode of recording of video, the mode of recording comprise automatic video recording and manually two kinds of video recordings.When selecting automatic video recording, system can open recording function automatically when reporting to the police, finish until reporting to the police, and video recording stops automatically.Need the manually start and end time of control video recording when manually recording.Video file can be saved under the path of system's appointment automatically.The user can read the interface by video recording and inquire about video file in certain time period, can delete video file simultaneously.
