Description

A remote calibration and single-person testing method for an optical fiber fence

technical field

The invention belongs to the field of optical fiber sensing technology and its application, and in particular relates to a remote calibration and single-person testing method of an optical fiber fence.

Background technique

At present, the fiber optic fence system is widely used in the fields of perimeter security, pipeline anti-sabotage, cable safety monitoring, and large-scale civil structure health monitoring. Disturbance signals such as vibration and strain are converted into changes in information such as phase, polarization, and light intensity of light, and photoelectric conversion is performed, and the collected disturbance signals are analyzed and processed at the processing terminal to realize the detection, positioning and identification of intrusion events. And realize the real-time security early warning monitoring of the fortified area.

When the optical fiber fence system alarms and locates, it can only locate the length of the optical cable at the intrusion disturbance point, but in actual applications, what the user needs is specific information such as the actual geographic location, cable number, and burying scene, and the length of the optical cable is different from the actual length of the fortified area or The distance is usually inconsistent, which is related to the binding method. For example, when the optical cable is laid in an "S" shape, the actual ratio of the distance to the actual space is generally 2.5-3. Afterwards, the calibration is carried out, that is, the simulated intrusion is generated through artificial disturbance along the line, and a one-to-one mapping relationship between the optical cable positioning information and the actual geographic location is established, and the optical cable positioning information, the actual geographic location, and the specific scene information that users care about are entered into the database in real time. The field disturber and the builder of the mapping table in the monitoring room communicate by telephone to determine the occurrence and end of a disturbance event and the description of the actual geographic location. Due to the differences in the description and subjective understanding of the two parties, communication is often poor, which directly affects the calibration work. Efficiency and accuracy of calibration information; on the other hand, after the fiber optic fence system is built, it is necessary to conduct a full-line test of the disturbance response sensitivity, and similar problems will also be encountered. The disturbance party outside the field cannot see the alarm response interface, while the response recorder Only the disturbance response interface can be seen, and information such as the cable binding situation at the disturbance point and the disturbance intensity cannot be accurately obtained. During the telephone communication between the two, the difference in subjective understanding of the type of intrusion event and the severity of the disturbance will also lead to testing. Information is unreliable and time-consuming. Since the monitoring area is usually several kilometers to tens of kilometers long, the calibration and testing process relies on mobile phone communication, resulting in large economic costs, and the person who generates the disturbance is different from the person who entered the response. In the process of communication between two people, there is inevitably communication and understanding difference.

A single-person testing method for an optical fiber fence according to claim 8, characterized in that: the specific method for processing the communication between the host and the handheld terminal is: The processing host creates a ServerSocket communication instance to specify the listening port, calls the accept() method to obtain the connected client Socket object, and interacts with the client information through the Socket input and output stream; The client creates a Socket and specifies the server IP and port number to initialize the TCP connection to the server, creates the connectToServer() method in SocketActivity, reads the information sent by the server, and adds user permissions in AndroidMenifest.xml to allow the application access to the Internet; Create a TCP listening thread on the server side, and loop to monitor whether there is a TCP connection request from the client. When receiving the connection request, the thread will open a new thread for TCP communication, and receive the data sent by the client in the new thread. And make a message response to complete the control interaction and monitoring data transmission of the handheld terminal to the fiber optic fence intrusion monitoring system. 10. A single person testing method for an optical fiber fence according to claim 7, characterized in that: after the handheld terminal receives the remote monitoring data and alarm location information based on the Socket communication connection mode, the handheld terminal draws and displays the optical signal real-time curve, and display the relevant information of alarm location on the interface of the handheld terminal; the specific method of drawing the signal curve is: draw the background image of the waveform display; mark the scale of the horizontal and vertical coordinates; map the waveform data to the coordinate system, and pass MoveTo( ), LineTo() and other functions connect the data points in series to complete the drawing of the optical signal waveform curve; continuously refresh the data to realize the real-time display of the optical signal waveform curve.
