Fig. 1 is a schematic structural diagram of the perimeter security blocking alarm system of the present invention;

Detailed ways:

Below in conjunction with accompanying drawing, the utility model is described in further detail:

Referring to Figure 1, a perimeter security blocking alarm system includes a controller and a front end of an electronic fence, the controller is connected to the front end of the electronic fence, the front end of the electronic fence is used for security blocking alarms, and the controller is used to generate two low-frequency peak voltages High-voltage pulse, the low-frequency high-voltage pulse output from the controller is transmitted to the front end of the electronic fence through the high-voltage insulated wire, and returns to the controller through the loop formed by the special alloy wire 1; Two loops generate a voltage with a security blocking effect on the front fence.

The controller is a packaged independent body, and there are digital display windows, indicator lights, output terminals and input terminals outside the controller; there is an alarm output socket on the right side of the controller, and an internal alarm control switch on the lower side of the controller; The controller generates low-frequency high-voltage pulses with two peak voltages, which are sent to the front fence to form a deterrent and blocking effect, and the indicator light indicates the output status of the pulse signal, and the digital display window monitors the operating status of the system; when there is an alarm such as an intruder When the situation occurs, the controller will detect that the front fence will cause open circuit, short circuit or touch the grid. At this time, the built-in alarm bell of the system will sound and output the alarm switch signal.

The front end of the electronic fence is composed of a hanging rod 2, an insulator, a terminal insulator fixing clip, a special alloy wire 1 and a special high-voltage insulated wire. The terminal insulator fixing clip is fixed on the special alloy wire 1.

The wire hanging rod 2 is a terminal rod, a bearing rod or an intermediate rod.

The insulators are terminal insulators, load bar insulators or intermediate insulators.

The front end of the electronic fence is also provided with a wire-wire connector and a tightener, and the wire-wire connector and the tightener are used for fixedly installing the front end of the electronic fence.

The front end of the electronic fence is composed of special alloy wires 1 arranged with four, six, eight or even up to 20 wires.

The controller is a packaged independent body in structure, and there are digital display windows, indicator lights and output terminals and input terminals on the outside. There is an alarm output socket on the right side, and an internal alarm control switch on the lower side. There are alarm bells, indicator lights and other settings inside. The function of the controller is to generate low-frequency high-voltage pulses with two peak voltages, high and low, which are safe for the human body, and send them to the front fence to form a deterrent and blocking effect, and the indicator light indicates the output status of the pulse signal, and the digital display window monitors the operating status of the system. When there is an alarm such as intruder intrusion, the controller will detect that the front fence will cause open circuit, short circuit or touch the net. At this time, the built-in alarm bell of the system will sound and output an alarm switch signal.

The structure of the front end of the electronic fence is shown in the figure. It consists of hanging rods 2 (divided into terminal rods, bearing rods and intermediate rods), insulators (divided into terminal insulators, bearing rod insulators and intermediate insulators), terminal insulator fixing clips and special Alloy wire 1 (bare wire) and special high-voltage insulated wire and other accessories. In addition, there are accessories such as wire-to-wire connectors and tighteners for the front-end installation of electronic fences. The front fence needs to be erected along the perimeter edge of the defense zone to realize the protection of the defense zone.

The low-frequency high-voltage pulse output from the controller is transmitted to the front fence through the high-voltage insulated wire, and returns to the controller through the loop formed by the special alloy wire 1 (bare wire). The high-voltage pulses of the two voltages pass through the special alloy wire 1 to form two high and low circuits, which can effectively deter and block the human body on the front fence. When an intruder climbs, climbs over, crosses or touches the fence, the front fence will generate a deterrent high-voltage pulse that is absolutely safe to hit the human body (the parameters of the high-voltage pulse strictly comply with IEC1011 (1989), IEC1011 (1991-09) and GB 7946 -87 standard), and send a corresponding alarm signal to make the intruder voluntarily evacuate.

The electronic fence can be composed of four-wire, six-wire, eight-wire or even up to 20-wire special alloy wires. Usually the distance between lines is 110-220mm. The more wires, the harder it is for intruders to climb, and the better the blocking effect. Customers can choose according to their actual situation and requirements. The length of the electronic fence can be expanded freely, and the length of a set of hosts can be linked from tens of meters to hundreds of meters, but the limit length should not exceed 10,000 meters.

The multi-zone system is mainly composed of multiple single-zone systems and zone controllers. Among them, each single defense zone system is composed of a defense zone detector and the front end of its protection area. Each defense zone detector is equivalent to the controller of the single defense zone system, and completes the high voltage pulse sending and receiving and alarming of the defense zone. The defense zone controller is connected in series with the detectors of each defense zone through the 485 bus to carry out remote arming, disarming, and alarm signal collection, and can be used as a back-end or an operating console in the control room.

This system is essentially different from the AC power grid. It adopts a low-voltage (6000-10000V) and low-energy (less than 5 joules) pulse system, and sends out a pulse signal per second, so it will not pose a life-threatening hazard to people. The flexible PV intermediate pole and special alloy wire of the electronic fence do not support the weight of the human body, but can sense the intrusion of the intruder and send out an alarm signal to ensure the safety and reliability of the system. The French LACME system has capacity expansion and provides a very convenient alarm signal output switching interface, which is compatible with other existing alarm monitoring equipment at home and abroad. It is conducive to further improving the safety level in the future and avoiding repeated investment in equipment.

The above content is a further detailed description of the present invention in conjunction with specific preferred embodiments. It cannot be determined that the specific embodiments of the present invention are limited thereto. Under the circumstances, some simple deduction or replacement can also be made, all of which should be regarded as belonging to the scope of patent protection determined by the submitted claims of the present invention.
