The tension type electronic fence consists of three parts: electromechanical components, electronic components and mechanical components. The electromechanical components are composed of a tension detector or the like. The tension detector is a device that responds to the behavior of attempting to invade by generating an alarm signal according to the tension characteristic of the electronic fence and relying on the steel wire that generates tension for climbing, pulling, and shearing. The zone controller is matched with the tension detector. It collects and processes the signals output by one or more tension detectors in the zone to determine whether an alarm is generated, that is, whether to provide the perimeter zone status signal to the system, such as an alarm or not. Wait for the action.
Tension electronic fence installation steps and product features
The tension type electronic fence is a collection of electromechanical devices that prevent physical obstacles and overcoming intrusion, such as climbing, pulling, shearing, etc., and is a new type of perimeter anti-intrusion alarm facility. It is a kind of "tangible" alarm system, and organically combines alarms and warnings to achieve the purpose of prevention and prevention.
Because of the new detection method and special signal processing method, the tension electronic fence of Keou has minimized the influence of environmental factors on the threshold change of tension alarm. Compared with other detectors, its environmental adaptability is more significant. improve.
System composition
Various component configurations:
1. The electronic components include a bus communication module and a DC power supply (power supply controller). The bus communication module is mentioned in the upper active-active perimeter warning system, which transmits the alarm signal of the detector to the alarm control host remotely. The bus communication module can be supplied by the tension cable manufacturer or by a third-party alarm system manufacturer.
Second, the DC power supply should be matched with the tension detector and the zone controller, which is generally provided by the tension fence manufacturer.
Third, mechanical components include wire ropes and installation, fixing, support and tightening of wire ropes, such as control rods, force rods, support rods, universal brackets, universal bearing brackets, springs, fastening nuts, etc.
During installation, a plurality of wire ropes are regularly installed and fixed between the control rod and the force receiving rod, and one end of each wire rope connected to the control rod is connected with a tension detector, and one end connected to the force rod is connected with a spring. , you can form a tension electronic fence. It can be a tension type electronic fence with 2 wire ropes, 3 wire ropes, 4 wire ropes, or a tension type electronic fence with more wire ropes.
The tension type electronic fence can be dedicated to work in the harsh environment such as wind, rain, snow, fog, dust, high temperature and low temperature. It adopts tension detection and special electrical signal processing, and has a wide dynamic range and high sensitivity. The level of false alarms for preventing animals can be set arbitrarily from 1 kg to 5 kg, ensuring such as leaves and birds. The interference of small animals does not generate an alarm, which ensures that the tension alarm system operates stably and normally.
The European-style tension electronic fence has these features:
Second, the tension module and controller are integrated design, easy to install and simple.
Third, the high-precision tension sensor can detect small changes in tension.
Fourth, a variety of alarm monitoring: steel cable tension, slack, shear, tampering, power failure, etc. are alarmed.
Five, innovative design detection method, adaptive temperature change, can automatically track.
6. Automatically compensate for the tension error caused by the change of ambient temperature, so that the system can run stably for a long time.
Seven, anti-climbing alarm: front fence detection rod, bearing rod, steering rod has anti-climbing alarm function.
Eight, the environment is adaptive: the steel cable can be automatically tightened according to changes in the external environment and climate, and the warning tension value can be adjusted.
Nine, the front end of the cable is not charged, widely used in schools, oil depots, government and enterprise units and other occasions.
Ten, with explosion-proof certification, explosion-proof certificate number: CLEx 19.1034
