Making ground Induction coil to consider the following points: 1, around 50 cm wide cannot have a lot of metal, such as well cover, rain gutter cover, etc.
2. within one meter cannot have more than 220V power supply line.
3. when making multiple coil, coil and the distance between the coil is greater than 2 m, otherwise it will interfere with each other. 1.2.1 cutting ground Induction coil trough in accordance with the drawings on the plan better Induction coil dimensions of a line, line with road surface cutting machine by cutting the coils of square Groove, requirements:

◆ Car ground Induction coil size typically 1.8 metres wide, about 1.2 m long
◆ Corner cutting 10 cm X10 cm chamfer, prevent hard concrete right angle cut coils.
◆ Slot depth 4 cm, coil trough width 0.5 cm, width of trunking coil cited is 1 cm, depth and width to uniform, should avoid suddenly deep and shallow, narrow and wide suddenly.
◆ In incising completed tank cannot have debris, especially not with hard objects to clean with water, then dried.
◆ Ground Induction coil of wire to cutting to refuges, avoid lead exposure in the pavement. 1.2.2 burial ground Induction coil winding Groove cutting and cleaning after drying, to timely burial coil, prevent debris falling into the tank. Making places as follows: 1. the Induction coil It's a good idea to clean the coils and cited a layer at the bottom of the Groove 0.5 centimeters thick sand, prevent forever tank bottom hard edges and corners cut wires.
2. Select the appropriate coil cable, wire diameter is larger than the requested: 0.5mm2 single root soft copper, coat and wear-resistant, heat-resistant, waterproof, such as selecting a fire wire.
3. online ring groove in the clockwise direction into 4 ~ 6 circle (circle) to the larger wires, coils, turn to the area (ring). Into the Groove of the wire should be no relaxation, stress, but also to a ramp to a zadi pressure tank bottom.
4. coil pin clockwise double stranded in the cited trunking, refuges-outlet stays 1.5 m long thread.
5. the coil and the leader in compaction of the Groove, it is best to spread a layer of sand 0.5 cm thick, you can prevent high-temperature molten crust is a coil.
6. use the molten hard asphalt or resin casting is put into a wire coil and cited trunking. After cooling and solidification of casting surface trough will continue pouring of settlement, so that repeated several times, until the cooling and solidification of casting surface after Groove and pavement.
7. test coil on-resistance and insulation resistance, verify that the coil is available. 1.3 cloth tube to be buried in concrete island of stuffing tube use PVC electric wire and tube, not only does not rust, and wall-slip easy Threading. Other stuffing tube under the fire code should use metal stuffing tube. Follow the tubing diagrams and equipment installation location to the following steps cloth stuffing tube: 1, the first layout to be buried in the refuges in the stuffing tube. Follow the device installation location determine the stuffing tube start and end points, the tube of the start and end points are to use Spring pipe Bender bend 90 ° elbow, elbow part in device installation location center set bundles and up on leads. Leadout higher ground 30 centimeters, the spout to temporarily block, prevent debris off when pouring concrete into. Need for fittings are used special glue sealant.
2, in an island-wide cloth tube, to the trend of rational arrangement of pipes, pipe layout is strictly prohibited in fixed device playing bulgy screw holes.
3, on import, export of stuffing tube. Determine the start and end of the pipe, the cloth KBG galvanized metal pipe, pipe connections are located 86 junction box. KBG metal tube and refuges of PVC pipe butt when you want to use 86 junction box. 1.4 making concrete island parking management system of the refuge is the equivalent of building housing Foundation, not only can host devices work stress (in particular barrier gate of stress can be up to several hundred kilograms), and can protect the equipment and lines, while standard access lane so that project a more professional appearance. Therefore, the making of the island directly affect system performance. Production of refuges in the following steps: 1, according to the drawing shape plan Island line.
2. If you are in soft soil ground on the island, shall be 50 cm above ground dug deep, and concrete pouring in the concrete or very thick stone floors shall be built refuges make every 10 cm density of reinforced and further reinforced mesh to the ground.
3. use of wood along the island shape lines enclosed a high 10 cm framework.
4, cement, stone, sand and a scale of 1: 1: 1 of concrete pouring wooden enclosed pedestrian refuge after the frame, pouring out horizontal plane. At least one week later, waiting for concreteCompletely solidified after drying, the use of high-grade cement Trowelling refuge surfaces.
5, in the island side brush yellow black 30 cm white traffic paints, etc. after drying, the island is produced. 1.5 stringing line is the basis for electrical engineering, line layout, connection quality have a direct impact on the system equipment works correctly, as well as the impact on the life of the equipment, especially with weak digital signal transmission of electrical engineering on line quality requirements are higher, the effectiveness of the quality system and line layout is reasonable, whether directly related to the specification, and therefore, control the quality of the wiring is the important work of electrical engineering. We use the following procedure for threading: 1. Selection of qualified, tested, parameters meet the national standards of Shenzhen jiaxiang "with" electric wire and cable. In the thread, wire and cable are first detected on-resistance and insulation resistance.
2. in accordance with the drawings on each line in the line of demarcation to wear, the thread you want to use special plastic stringing machine, you cannot use the wire, so as not to scratch the wall or in the other wires.
3. the required connector cable, connector with solder welding and heat shrinkable tubes, power cord, heat-shrinkable tube also wrapped in electrical tape.
4. put on the line once again testing on-resistance and insulation resistance, if you have questions, want to change line in a timely manner. Test good line to drawings required number pipe marking line number.
5. put all the lines, all outgoing line points to tie with cable ties, wiring strip tubes plastic belt package, so that rainwater into the pipeline. Install the equipment in accordance with the drawings 1.6, equipment placed on the island on their installation locations. Place the device should protect the following pipelines: 1. According to the drawings to confirm the device location correctly, use a pencil to trace the device cradle mounting holes in the mounting plane, and mark the center point, and then the device is moved away.
2. use the hammer φ 16 head straight down beat the mounting hole, the hole depth to 10 centimeters, go out and rock to timely clean and play good holes should not junk.
3. the national standard specifications of φ 12 bulgy screw pressed into the holes of each installation, and fixed nut, requirements of fixed anchors cannot rotate together with nut and screw part exposed should be less than 4 cm.
4. screw off the expansion screw nut and save puts the device into the installation location, the required screw holes are cradled fixed.
5. at each screw diameter greater than dropping it on a 20 flat gasket and a spring washers, locking nuts. 6. equipment fixed, hand push equipment, feeling it fixed firmly. 1.7 wiring

In accordance with the diagram of the pipe line number tables to confirm each thread uses the control device wiring diagram each line is connected to the corresponding terminal block: 1. Multi-core cables to each core wires marked with numbers on the pipe core, and core, and the color of the record that corresponds to this is cable the other end of the connection.
2. the connection is not to be conductor copper core direct screw terminal block, so easy to fall off a long time, and the split-core will reduce signal transmission quality and causing a short circuit. Should every wire of end use dedicated Press pliers to suppress metal receiver and metal screw terminal block takeover.
3. the connection is completed to thoroughly clean cut lines first debris, especially bare copper conductor head so as not to cause a short circuit is damaged when you power up the device.
4. binding arrangement and terminal connections of the leader, the signal cable and signal wire collation, power cord and power cord, so as not to interfere with each other. 1.8 system debug system debugging follow these steps:
