Problems solved by technology

[0003] The vast majority of electronic fence systems are still under single-device decentralized management, and once an alarm occurs, the alarm signal can only stay at the front end. When connected to the front end, no matter whether there is tension, relaxation, or disconnection, only one When the switch signal comes out, it can only detect whether it is an alarm, but cannot distinguish its alarm state. When an alarm occurs, it is impossible to determine whether someone has invaded or the fence has been destroyed, which is not conducive to grasping the exact information and making an accurate response.

Embodiment 1

[0059] to combine figure 1 , a tension-based electronic fence comprising a fence, including a physical layer, a sensing layer, a control layer, and a network layer.

[0060] Among them, the physical layer includes tension fence unit, video linkage unit and alarm unit, such as Figure 6 , when it is detected that the fence unit has an intrusion abnormality, the alarm signal is transmitted to the video linkage unit through the serial port, and the video linkage unit performs command analysis according to the received serial port data, and then decides whether to start video acquisition. The tension fence unit and video The linkage units are all connected to the alarm unit.

[0061] The sensing layer, including the sensor components installed in the tension fence unit, detects the state of the fence unit in real time, and transmits the detected signal to the fence host 1 .

[0062] The control layer includes the fence host 1 located on the fence and the host computer for contro...

Embodiment 2

[0066] On the basis of embodiment 1, the described alarm unit includes an alarm host, an alarm module and an alarm 3, and the described alarm host receives monitoring data from the sensing layer, and connects the detection data to the host computer through the network layer, The alarm host analyzes and processes the monitoring data through the alarm module, and starts or closes the alarm 3 according to the processing result, and the alarm 3 is arranged on the fence, and the alarm module includes:

[0067] In the tension alarm module, if the detected tension is greater than a certain threshold for a period of time, it will be judged that there is a tension abnormality and an alarm will be issued; in the slack alarm module, if the detected tension is lower than a certain threshold for a period of time, it will be judged that there is a relaxation abnormality and an alarm will be issued. Alarm; open circuit alarm module, when there is a signal short circuit, it will judge that the...

Embodiment 3

[0072] On the basis of embodiment 1, described sensor assembly comprises:

[0073] The tension sensor 15 is located in the control rod 2 and is connected to the corresponding tension cable 8 through the tension spring 13 to detect the tension change of the tension cable 8, and each tension cable 8 corresponds to a tension sensor 15;

[0074] Inertial sensors are laid on the fence in groups through tension cables 8 at intervals of 2-3 meters, and the intrusion signals are collected and input to the fence host 1 for analysis or directly input to the alarm host for analysis. The inertial sensors are installed in common defense zones Inside;

[0075] The vibration sensor is attached to the tension cable 8, senses the weak pressure and deformation transmitted from the surface of the tension cable 8, collects the intrusion signal and transmits it to the fence host 1 or directly inputs it to the alarm host for analysis, and the vibration sensor is installed In the key defense area, ...

Abstract

The invention relates to a tension-based electronic fence, which comprises an enclosing wall, and comprises a physical layer which comprises a tension fence unit, a video linkage unit and an alarm unit, and the tension fence unit and the video linkage unit are both connected to the alarm unit; the sensing layer comprises a sensor assembly and is used for detecting the fence units in real time and transmitting detected signals to the fence host; the control layer comprises a fence host and an upper computer used for controlling the fence host, the video linkage unit and the alarm unit; the network layer transmits, analyzes and processes the front-end data of the physical layer in real time through the Internet and a cloud system and uploads the front-end data to an upper computer; according to the electronic fence provided by the invention, various detection means are used at the front end, various sensors form a sensing network, data analysis is carried out through a fusion algorithm, and the accuracy and reliability of alarm are improved.

Description

technical field [0001] The invention belongs to the field of security technology, and in particular relates to a tension-based electronic fence. Background technique [0002] Modern geo-fencing devices can distinguish between malicious and unintentional intrusions. And it can prevent the intelligence from identifying the location of the intrusion, and will not bring fatal damage to the intruder. The voltage output of the pulse host connected to the electronic fence complies with various international standards / national standards. The low-frequency, low-energy, high-voltage pulse voltage (5,000 volts to 10,000 volts) has a very short time for the voltage to act on the body of the person and will not harm the intruder. To cause harm, the pulse voltage can be adjusted at will through the pulse electronic fence host, and is suitable for various places with different protection level requirements. [0003] The vast majority of electronic fence systems are still under single-dev...
