Embodiment Construction

[0031] Such as figure 1 , 2 An intrusion detection fence shown in . Together. Such as Figure 4 The shown sensor node 3 includes a sensor sensing module 4, a microprocessor module 5, a communication module 7 and a power supply module 6; wherein the sensor sensing module 4 is used to sense various changes such as vibration or temperature or tension on the fence, And these physical quantities are mapped into computer-recognizable digital signals, the sensor sensing module 4 includes at least one of a vibration sensor and a tension sensor, and the microprocessor module 5 is used for data processing collected by the sensor sensing module 4, The intrusion behavior is identified, and the communication module 7 is used to transmit the alarm result obtained by the processor to the command center.

[0032] Such as figure 2 , 3 The middle part of the hollow column 1 is provided with a detachable cover plate 8, and the sensor node 3 is located in the cavity of the hollow column 1 ...

Abstract

The invention discloses an intrusion detection fence which comprises a hollow upright and fence net pieces and is characterized in that: a sensor node is arranged in the hollow upright and combined with the hollow upright and the fence net pieces. The intrusion detection fence can detect the intrusion behaviors of climbing and damaging (including shearing and gas cutting) the fence and adapt to severe environment, does not generate many false alarms, and is invisible and beautiful and easy to mount and maintain. In the production process of the fence, joints of embedded equipment are reserved, the leads are threaded in the production process, and the sensor node is mounted in a corresponding slot of the fence on the site only. When the sensor node fails, the sensor node is replaced.

Description

technical field [0001] The invention relates to an intrusion detection fence. Background technique [0002] At present, the anti-intrusion methods based on fences are mainly divided into two categories: attached fence detection systems and independent fence systems. [0003] The fence-attached detection system is to fix the sensing equipment to the fence, such as vibrating optical fiber, infrared radiation, and vibration sensor network are all such detection systems. [0004] The cost of infrared radiation is very low, but the environmental adaptability is poor, and it is easy to false alarm in foggy days, and the alarm cannot be triggered if the fence is destroyed. [0005] The cost of vibration optical fiber and vibration sensor network is low, and they all judge the intrusion behavior by detecting the vibration of the fence alone. For vandalism that does not cause significant vibration of the fence, such as gas cutting, vibration detection alone is powerless. [0006] ...
