Hello everyone, I'm Brother Xue. Recently, the readers of the VIP member group consulted the design scheme of the electronic fence system, and today I share a general electronic fence system solution material, which is recommended to be collected for later use.
This complete set of word program materials, VIP members**!
The perimeter prevention subsystem can identify and respond to various intrusion events in a timely manner, and has the characteristics of long-distance monitoring, high-precision positioning function, low energy dependence, high environmental tolerance, anti-electromagnetic interference, and anti-corrosion. The system is developed on the first monitoring integrated management system, based on embedded intelligent visual analysis technology, in the perimeter prevention of the problem of using it has intrusion detection alarm and target automatic tracking function module, in addition to the traditional perimeter prevention system terminal alarm function, its biggest advantage is that it can view the monitoring screen in real time, timely positioning and tracking of the intrusion target, sound and light warning and other intelligent innovative functions for cross-border behavior, the intrusion event can be contained in time, In this way, the losses are minimized to the greatest extent.
The system can do dynamic monitoring of the monitoring area from macro to detail, forming a whole process security system of pre-warning, warning and post-evidence collection, which truly improves the prevention function of security monitoring and breaks the original security"Hindsight"The single mode can timely detect the intrusion trend for early warning and processing, and the improvement of the security level greatly reduces the incidence of illegal events, transforms the security from passive monitoring to active supervision, and smoothly escorts social security protection.
The system should be used for the perimeter perimeter fence area of the building or the exterior wall area of the internal building. It not only has the role of intrusion alarm, but also can understand the situation of the monitoring area in real time through the front-end monitoring equipment, once the intrusion occurs, it can issue a warning at the first time, and can timely inform the security personnel to rush to the place of the crime to deal with it, so that the intruder does not really commit illegal acts before the crime is terminated, and the loss is reduced to a minimum.
The system architecture is shown in the following figure:
Figure 1Geo-fence system architecture.
The electronic fence system has the triple functions of deterrence, blocking and alarm, deterrence: intruders will have psychological pressure when they see the warning signs; When touching the fence and having an electric shock, they will give up the invasion because they are more afraid; Blocking: Electronic fences are physical barriers, with heights and angles that are difficult to climb, and electric shocks, so they can block intruders; When an intruder forcibly breaks through, the system host will send an alarm signal.
The system is mainly responsible for preventing illegal intrusion in the community, and after the system is realized, it should be able to link with the CCTV monitoring system. On the basis of the first operation of each sub-system, it must work together and cooperate with each other to give full play to the maximum ability of safety prevention.
The alarm system is composed of an alarm control host, a detector and an acousto-optic alarm device, and has the following alarm functions:
Centralized area alarm: all arming areas need to be armed by the general control room of the alarm system, through the software settings, some defense areas can be gathered together, respectively define the type of defense area (access defense area, peripheral defense area, internal defense area, emergency alarm defense area, emergency help defense area). Each defense zone is separately connected to the system controller, and the software receives the status information of each defense zone in real time (alarm alarm recovery), and responds according to the operation status (arming, disarming or bypassing) set by the software.
Alarm linkage: through the alarm linkage relay module, the driving mode and action mode can be customized: it can be driven by some defense area or subsystem alarm, arming and disarming, bypass and other states, and output alarm data through the specified serial port or switch, and realize linkage with the CCTV (TV monitoring) system of the residential building.
After completion, the electronic fence has the following advantages:
1. It has a strong deterrent function: electronic fences and warning signs give criminals a great psychological deterrent effect and prevent them from committing criminal acts;
2.Strong active protection: give an electric shock when attempting to cross;
3.Strict prevention without dead ends: regardless of the size of the perimeter of the community and the complex terrain, it can be erected arbitrarily according to the terrain, without dead ends and blind spots;
4.Virtually no false positives: prevents false positives caused by small animals;
5. Electronic map function: once the alarm occurs, the control center will immediately display the alarm location, and arrange the nearest security personnel to view and deal with the alarm.
