Schematic diagram and installation steps of electronic fence

1. Preparation before construction of the electronic fence

1. Construction tools: conventional construction tools such as hand drills, electric hammers, wire cutters, wire strippers, screwdrivers, wrenches (12-14' 1-12), scaffolding, safety belts, etc., which are necessary for construction. According to the on-site construction situation, wire threaders are needed when encountering weak current wells.

2. Construction materials: prepare materials such as RS485 twisted-pair or network cable, twisted-pair shielded cable, sheath line, 2 PVC threading pipe, power sealant tape, cable ties, etc.

3. Safety preparation: Construction safety warning lights and safety warning signs with warning slogans need to be hung at the construction site.

The physical picture of the whole set of electronic fence after installation is as follows:

II. Installation of the middle column of the stress column:

If it is a solid fence, first punch holes with an impact drill at the top of the fence, and the standard hole diameter of the installation base is 8 mm, so the drilling bit should be 12 mm, and the expansion screw should be 8 mm thick and 7 cm long to use.

The schematic diagram of the fixed stress column is as follows:

According to the above figure, the stress column base of Oumai electronic fence consists of two bases, which are fixed with 8 expansion screws and 4 holes, and the angle can be adjusted infinitely (you can choose to install it vertically at 9 degrees or obliquely as shown in the figure), and a circular hoop washer is added in the middle, and nuts and gaskets are added outside, thus ensuring the overall strength of the fence.

In addition, the whole thickness of the base is more than 3mm, and it is hot-dip galvanized without embroidery, and its service life can reach at least 5 years.

The schematic diagram of the fixed middle column is as follows:

The middle column of Oumai electronic fence adopts a single base, and the thickness is also a high-quality hot-dip galvanized base with a thickness of more than 3mm.

the installation angle is also an arbitrary stepless adjustment angle.

The physical diagram of the mounting base of the electronic fence is as follows:

After getting the stress column, intermediate column and fixed base of the electronic fence, it can be installed obliquely or vertically according to the site conditions.

as shown in the following figure:

III. Installation of alloy wires

After all the pedestals and columns are installed, it is time to pay out the alloy wires.

advantages of perforated installation: the whole system is insulated, so there will be no short circuit, and the spacing will be fixed forever, so there will be no short circuit caused by insulator falling off, and criminals will not be given an opportunity.

If the perimeter is several thousand meters, it will be a waste of manpower and financial resources to investigate one by one. Can't find problems in time and deal with them in time. Similarly, the alarm caused by short circuit will become a false alarm.

iv. Installation of the tightener

Directly thread the alloy wire through the hole in the middle of the tightener (as shown in the figure below), the main function is to straighten the alloy wire, so as to avoid that the alloy wire is too loose, which will affect the overall beauty. In addition, if it is too loose, it is easy to cause two wires to be short-circuited.

firstly, punch a hole on the stressed column with a hand electric drill (it is punched by default), then use a hook to pass through the black insulator, and then hang it on the column (as shown below). The function of the clamp is to clamp the alloy wire to prevent it from falling off.

installation of lightning arrester

lightning arrester must be installed on the electronic fence erected in the area where lightning occurs in the open space or at a certain height. The lightning arrester should be installed at the beginning of the electronic fence and hung on the first alloy wire of the electronic fence, and the bottom needs to be connected to the earth. The arrester should be installed correctly according to the instructions for use.

In addition, special lightning arresters for electronic fences must be selected to better protect the pulse host. At present, lightning arresters in China are all made of zinc oxide with poor quality, so it is impossible to check them after lightning strikes. Using the electronic fence (imported from Britain) arrester specially designed for Shanghai Oumai, you can see with the naked eye whether it has been struck by lightning, as shown in the following figure. Transparent semi-circular lightning arrester, if struck by lightning, the core inside will turn black.

imported transparent lightning arrester turns black after being struck by lightning

suspension and installation of warning signs

the suspension of warning signs must be carried out according to the specifications, and it is a wrong suspension method to fix only two holes. The correct suspension method is to fix three points with tie straps at the same time (as shown in the figure). Oumai Company calls it "three-point suspension method"

Fix warning signs

Install the high-voltage line and the case of the pulse generator

Generally, the pulse generator and the rain box are placed between two defense zones. If the 2-meter perimeter is divided into two defense zones, then the pulse generator and the rain box will be fixed at a position of 1 meters, that is, between the two defense zones.

At this time, the front end of the perimeter pulse electronic fence has been completely installed, and the schematic diagram of the connection between the pulse host and the electronic fence is as follows:

For example, the electronic fence we usually see is four alloy wires, so the link method at the end is to skip 1 and 3, and skip 2 and 4. It is wrong to jump between 1 and 2, 3 and 4. (as shown in the figure below)

Transmission schematic diagram of electronic fence system

After the host computer in the protected area is connected with the front end of electronic fence, it needs to be powered on for testing, mainly to test whether it is short circuit or short circuit alarm or not. If the test can give an alarm normally, it is finally docked with the alarm host at the end.

Extended information

Components of installing electronic fence system:

1. Electronic fence host:

Electronic fence host includes single and double protection zone pulse host, rain box, lightning arrester, grounding system and high-voltage line

2. Front end of electronic fence:

Stress column (including fixed parts and decorative caps) and intermediate column.

long perimeter uses bus alarm host (including address code module), short perimeter uses branch alarm host (excluding address code module), alarm control keyboard and audible and visual alarm (indoor).

if the standard luxury configuration is involved, there are control server, operation management software, serial port module, display screen, linkage module (linkage monitoring probe), mobile phone APP, Wifi control module, OUM485D hand-in-hand optical transceiver (long-distance transmission needs more than 2km).
