Electronic fence alarm device

Abstract

The invention provides an electronic fence alarm device. The electronic fence alarm device comprises a fence base, an alarm and a control device, wherein the upper end of the fence base is provided with two support rods, pulse transmission lines are transversely connected between the two support rods, a plurality of middle rods are evenly arranged between the two support rods, a fixing rod is arranged at a middle position between the two support rods, the control device is connected signal transmitters, the signal transmitters are connected with the pulse transmission lines, the pulse transmission lines penetrate the support rods, the middle rods and the fixing rod, two rotary line tighteners are mounted on each pulse transmission line and are close to the support rods, and each rotary line tightener is provided with a pressure sensor; the alarm is arranged at the top of the fixing rod and connected with the same through an alarm support column; a plurality of visible laser probes and invisible laser probes are arranged on the surface of the alarm. The electronic fence alarm device is firm in connection, high in safety and capable of effectively lowering false alarm probability.

Description

technical field [0001] The invention relates to the technical field of security equipment, in particular to an electronic fence alarm device. Background technique [0002] The electronic fence is currently the most advanced perimeter anti-theft alarm system, which consists of an electronic fence host and a front-end detection fence. The electronic fence host generates and receives high-voltage pulse signals, and can generate alarm signals when the front-end detection fence is in the state of touching the net, short circuit, or open circuit, and sends the intrusion signal to the security alarm center; it has high security levels such as anti-theft and alarm. Boundary defense function. [0003] Compared with traditional infrared, microwave, electrostatic induction and other perimeter security systems, the pulse electronic fence has obvious advantages such as low false alarm rate, no terrain and environmental restrictions, and high security. It has been widely used in World Ex...

Problems solved by technology

[0004] However, the wires of the pulse electronic fence have weak electricity, which makes people feel electric shock when they touch the fence, but it will cause a certain degree of harm to children and small animals, increase the probability of false alarms, and bring unnecessary troubles

At the same time, the pulse electronic fence in the prior art has a small span. When it is applied to a large area, the transmission line of the pulse is easy to relax. When a strong wind passes by, the transmission line will swing violently, and contact failure is likely to occur at the connection at both ends.
