With reference to Fig. 8 and Fig. 9, GPRS monitor terminal 2 is also by the monitoring of network state detection device and with LED display network state, by power supervisor and unlatching or closing device power supply.These accessory circuits are not given unnecessary details.
Treated field image signal is stored in the database 31 after adopting ICP/IP protocol to be sent to the system server 3 of network.Database provides image querying, broadcast and editor, makes the image information that the user can consult at any time to be needed.The user uses GSM mobile handset to record, store, consult, download, to be provided with etc. on-the-spot sound, and the mobile phone that uses GPRS or CDMA-1X to have multimedia message or CAI e business can be stored, consults, deletes, downloads, check the scene, warning etc. is set to image.
With reference to Fig. 3, the software to system elaborates below.The software of system is made up of following four parts: the alarm monitoring program; The user profile setting program; Alarm information processing program and historical data management program.
In an embodiment of the present invention, image processor 10 stores the sequence of operation of alarm monitoring program.With reference to Fig. 4, this sequence of operation is carried out following operating procedure:
1) information-setting by user is checked in system start-up;
2) start imageing sensor;
3), send that " hello, and welcome if the detection scene has the people to swarm into! " voice;
4) detect light whether can, if can, carry out 5), if not, carry out 6);
5) imageing sensor enters shooting, and speed is 1 time/second;
6) start secondary light source;
7) whether the detection target shifts out target and shifts out warning region, if carry out 9), if not, carry out 8);
8) whether the detected image transducer has finished the 10th signal shooting, if carry out 9), if not, return 5);
9) extract the intermediate binary image sample and send this image pattern and return 1);
10) check whether the user starts and intercept, if carry out 11), if not, return 1);
11) receive and send this interception information;
12) return 1), system closure.
System server 3 stores the sequence of operation of user profile setting program, and with reference to Fig. 5, this sequence of operation is carried out following operating procedure:
1) user computer is netted legal login wireless network safety-protection system by Internet net or mobile phone by GPRS;
2) reception user's configuration information;
3) configuration information is saved in database;
4) the GPRS monitor terminal of selection user appointment;
5) detect the user and whether connect this GPRS monitor terminal, if information-setting by user is sent to the GPRS monitor terminal; If not, return 2);
6) system closure.
System server 3 stores the sequence of operation of alarm information processing program.With reference to Fig. 6, this sequence of operation is carried out following operating procedure:
1) system start-up, system server receives the warning message of GPRS monitor terminal, and warning message is saved in database;
2) querying condition that is provided with by the user obtains warning message from database;
3) detect the user and whether use the e-mail of appointment to send warning message, if then warning message is sent in the e-mail of user's appointment; If not, carry out 4);
4) mobile phone that whether detects to user's appointment sends warning message, if carry out 5); If not, return 2);
5) detect user mobile phone and whether have function of multimedia message, if transmission has the warning message of alarm image in the mobile phone of user's appointment; If not, transmission does not have the warning message of alarm image in the mobile phone of user's appointment;
6) system closure;
System server 3 stores the sequence of operation of historical data management program.With reference to Fig. 7, this sequence of operation is carried out following operating procedure:
1) user computer is netted legal login wireless network safety-protection system by Internet net or mobile phone by GPRS;
2) selection user's querying condition;
3) historical information of querying condition is satisfied in inquiry and demonstration;
4) detect the user and whether download or history of printing data and warning picture, if the user can download or history of printing data and warning picture by operation, returns 2 then); If not, carry out 5);
5) detect the user and whether change or deleting history data and warning picture, if the user can change or deleting history data and warning picture by operation, returns 2 then); If not, carry out 6);
6) withdraw from administration page, system closure.
The result of operational system software is that image and other alarm signals are emitted in the cdma network of the GPRS network of communication company of China Mobile and CHINAUNICOM with wireless the most at last, on this two big cellular carrier particular network server, after carrying out the IP address resolution, just the signal of on-site supervision can be sent on user's the mobile phone or in the E-mail address of user's appointment.
