Worker carries handheld terminal and the diverse location of detecting optical cable carries out disturbance or destruction at random, the light pulse signal phase place and the polarization information that transmit in optical cable change, light pulse signal after the disturbed modulation that back scattering is returned, receive through described optical signal demodulation equipment and carry out photoelectricity and analog digital conversion, and transmit to processing main frame;
Process main frame to be analyzed optical signal in detecting optical cable processing, it is judged that optical signal is with or without changing and positioning;
Handheld terminal accesses GPRS network, utilizes GPRS network to set up and processes hosi wireless communication, processes main frame and is transmitted optical signal real time data and warning location related information to handheld terminal by wireless network;
Handheld terminal draws display optical signal real-time curve, and by warning location related information in handheld terminal interface display;
Worker has unchanged by monitoring handheld terminal interface optical signal curve and has alarm free location information alert to judge this optical cable disturbance response sensitivity, it is achieved the single test of fiber fence disturbance response sensitivity.
8. a kind of single method of testing of fiber fence according to claim 7, it is characterized in that: described process main frame and handheld terminal are to be communicated by Socket, adopting customer end/server mode, handheld terminal makes client, and fiber fence system for monitoring intrusion makes server end.
9. a kind of single method of testing of fiber fence according to claim 8, it is characterised in that: processing the main frame concrete grammar that communicates with handheld terminal is:
Process main frame and create a ServerSocket communication instance appointment listening port, call accept () method to obtain the client Socket object of connection, and mutual by Socket iostream and client-side information;
Client one Socket of establishment given server IP and port numbers are initialised to the TCP of server end and connect, SocketActivity creates connectToServer () method, read the information that server end sends, and in AndroidMenifest.xml, adding user right, it is allowed to application program accesses network;
A TCP watcher thread is created at server end, circulation monitors whether there is the TCP connection request from client, when receiving connection request, this thread can open a new thread for TCP communication, new thread receive the data of client transmission and makes message response, completing the handheld terminal control to fiber fence system for monitoring intrusion and transmit with Monitoring Data alternately.
10. a kind of single method of testing of fiber fence according to claim 7, it is characterized in that: described handheld terminal is after the mode that communicates to connect based on Socket receives long-range Monitoring Data and warning location information, display optical signal real-time curve is drawn at handheld terminal, and by warning location related information in handheld terminal interface display; The concrete grammar that its signal curve is drawn is: draw waveform display background figure; The scale of mark transverse and longitudinal coordinate; Wave data is mapped in coordinate system, and by functions such as MoveTo (), LineTo (), data point is together in series, complete the drafting to photosignal waveform curve;Constantly to Refresh Data, it is achieved photosignal waveform curve shows in real time.
