Tension type electronic fence adopts tension detection technology, that is, each steel wire host end of the fence is equipped with a tension sensor, and the MCU 24-hour continuous monitoring of the force of each steel wire to achieve an alarm. Because the alarm is judged by the tension of the wire. The front-end steel cable is not charged, and is widely used in schools, oil depots and other occasions. On the basis of these functions, Keou's tension type electronic fence has new functions.
1. What are the new functions and new features of Keou tension electronic fence?
Anti-climbing alarm function: at a distance of 700mm from the bottom of the fence at the control rod, load-bearing rod and bearing rod, apply an external force of not less than 100N to the vertical direction of the plane formed by the rod body and the steel cable, and continue for more than 2s, corresponding to The body of the rod will issue a climbing alarm.
Automatic cable tightening function: adjust the tested cable to the normal warning tension range, at this time, loosen the tensioner (not more than 75mm, 2-3 turns), so that the tension value of the cable is within the set value of the product In addition to the normal warning value, within 20s, the alarm system can detect the slack of the wire rope and automatically tighten the wire rope to restore the tension value of the wire rope to within the normal warning tension value set by the product.
Below, for the installation of the new function of the tension fence, I have compiled some videos and high-definition pictures for everyone.
2. Preparing accessories
The new function of the tension type electronic fence needs to be equipped with a tension gas spring, a new function terminal force bar, a matching universal base, and a warning sign.
3. Installation of guest European tension electronic fence
When installing the rod body, try to keep it on the same horizontal line to reduce the friction between the tension wire and the thread hole and ensure the sensitivity of the tension fence. When there is a high-low drop or horizontal steering, the load-bearing rod (that is, the terminal rod) and the steering pulley should be used.
Control lever installation:
Normally, the control rod outlet hole is installed toward the inside of the wall, fix the control rod with a large base, and then use the expansion screw to fix the large base on the wall.
Terminal pole installation:
Normally, each defense zone needs a terminal pole, according to the actual installation environment. The terminal rod needs to be fixed with the base, and then fixed on the wall. If a corner appears in the defense zone, a load-bearing rod (that is, a terminal rod) needs to be installed at the corner.
Support rod installation:
A support rod is installed every 3-5m in the middle of each defense zone, and the support rod needs to be fixed with a universal base.
Installation of tensioner and tension gas spring:
Normally, each tension wire needs several tensioners to adjust the tightness of the tension fence. The tension wire passes through the center of the tensioner and is fixed at the other end with a harness.
The tension gas spring is usually installed near the terminal rod of the defense zone, and both ends are fixed with a cable tie. Under normal circumstances, the tension gas spring should be in a stretched state.
Installation of warning signs and outdoor warning lights:
A warning sign is installed every 10 meters, and the warning sign is installed according to the specific environment.
Installation of the base:
4. Installation standard of tension type electronic fence
System power supply:
Tension type electronic fence power supply: power supply in the form of centralized power supply in the computer room. Considering that the system is configured with an active infrared intrusion detector, the conventional active intrusion detector power supply requires DC voltage power supply. To facilitate construction and installation and save costs, the system should be powered by DC power supply, that is, DC24V / 8A.
Lightning protection grounding:
The control rods should have independent and reliable grounding devices, and the grounding resistance should not be greater than 4Ω.
System ground:
System grounding is an important content that cannot be ignored in weak current engineering. The grounding system includes: lightning protection grounding, AC working grounding, DC working grounding, safety protection grounding, shielding grounding, and antistatic grounding. The grounding method adopts a joint grounding method, that is, lightning protection grounding, working grounding, protective grounding, etc. are directly connected to the grounding grid, and the total grounding resistance is less than 1 ohm.
Principles of the defense zone setting of the tension type electronic fence:
Each defense zone of a conventional straight wall does not exceed 40 meters. The length of each defense zone in the arc fence or the place where there is a turn shall not exceed 30 meters.
Active infrared detectors should be installed in places where tension-type electronic fences are not suitable for installation (such as side doors, weak walls, etc.) to ensure that the entire system is free from dead spots.
In general, the height of the tension fence is greater than 750mm. The distance between the next tension line and the actual wall is between 130mm and 150mm, and the distance between the remaining two adjacent tension lines is 200mm.
The installation of the tension electronic fence has been introduced, and everyone has a general understanding. Keou is a professional manufacturer of tension electronic fences and pulsed electronic fences. Keou not only provides products, but also provides services. Keou provides you with services. Provide a complete set of after-sales service to guide the installation.
note
The installation record is introduced under normal circumstances, and it needs to be flexibly adjusted according to the actual situation!
The key products are lead containing stabilizers, which is produced in our lead salt factory, we also can supply tributyl citrate, dicumyl peroxide, diethyl sebacate, triphenyl phosphate and so on.
1. Product name:Dicumyl peroxide (DCP)
2. Applications:DCP, as an excellent organic peroxide, is mainly used as the crosslinking agents of PE, EVA resins; the vulcanizing agent of EPDM, natural rubber, nitrile rubber; the initiating agent of polymerization reaction; the curing agent of unsaturated polyester; and the conditioning agent in polypropylene melt index, etc. It is widely used in wires and cable, EPS, shoemaking, fire retardant paint and other industries.
