Embodiment 1

[0022] A strain-type tension fence alarm system, comprising a column 1, a tension line 2, a sensing pile 9, a strain sensor 7, a steel wire 3, and a lock plate 4, the column 1 is installed on the ground, and the column 1 is horizontally installed with a tension line 2 , the tension line is supported by the middle pile, the middle pile 12 is arranged parallel to the column, the side of the middle pile is provided with a bracket 13 for supporting the tension line, the tension line 2 and the vertically arranged steel wire 3 are knotted at the intersection, and the steel wire 3 A lock disc 4 is installed at the intersection with the tension line 2, and the lock disc horizontal direction is set

[0023] There is a perforation 5 for the tension line to pass through horizontally, and the vertical direction of the lock plate is provided with a perforation 5 for the steel wire to pass through vertically. The lock plate is formed by butting two symmetrical round boxes 6. The small hole ...

Embodiment 2

[0027] When someone climbs the tension line 2, the steel wire 3 is pulled, and the steel wire 3 can transmit the force to the strain gauge sensor 7. At the same time, the perforation can limit the tension line 2 and the steel wire to avoid knots caused by people climbing. Stress concentration results in breaking and breaking, and the strain gauge sensor 7 transmits a signal to the alarm device through the controller, thereby generating an alarm to remind someone of intrusion.

Abstract

The invention discloses an alarm system for a strain type tensile fence. The alarm system is characterized by comprising an upright post, a tensile line, a sensing pile, a strain sensor, a steel wireand a lock disk, the tensile line is transversely mounted on the upright post, and a knot is tied at the intersection between the tensile line and the vertically arranged steel wire; the lock disk isinstalled on the intersection of the steel wire and tensile wire, two ends of the steel wire are connected with the strain sensor, and the strain sensor is horizontally mounted on the sensing pile; the strain sensor is connected with a controller, and the controller is connected with a monitoring device. According to the alarm system, the steel wire and the tensile line are tied, when a person climbs the tensile line, the steel wire is pulled, and the steel wire can transfer the force to the strain sensor, thereby generating alarm.

Description

technical field [0001] The invention relates to the technical field of alarm devices, in particular to a strain-type tension fence alarm system. Background technique [0002] Today's tension fences are widely used, for example, they can be used in airports, prisons, borders, nuclear power plants and other highly sensitive equipment. No alarm will be generated when crawling intrudes. Contents of the invention [0003] The object of the present invention is to solve the above problems, and a strain-type tension fence alarm system is designed. On the top of the wall, a tension line is horizontally installed on the column, and the tension line is supported by an intermediate pile, which is arranged in parallel with the column. The tension line and the vertical steel wire are knotted at the intersection, and a lock plate is installed at the intersection of the steel wire and the tension line, and the two ends of the steel wire are connected to the strain sensor, and the strai...
