Third, building standards
1. Building standards for safety island
Build a round concrete pillar in middle of road, known as a traffic island. The safety island is mainly used to accommodate equipment and prevent vehicles from colliding with equipment. If equipment is installed on side of road due to road width restrictions, then foundation for installation of equipment must be made on side of road.
The security island of car park barricade control system is equivalent to foundation of a building. It can not only withstand load of equipment during operation, especially load of barricade can reach hundreds of kilograms, but also protect equipment and lines, and regulate entry and exit of vehicles to make project look more professional. Thus, production of an island of safety will directly affect performance of system.
To create a safety island, do following:
1) Draw shape lines of traffic island according to drawings.
2) If site has soft soil, earth must be dug up to a depth of 50 cm and poured with concrete.
3) Cover frame with a height of 15 cm with wooden boards in form of a safety island.
4) Pour concrete with a ratio of cement, stone and sand of 1:1:1 and overlay frame of safety island with wooden boards. Find out water level after pouring. At least a week later, after concrete has fully set and dried, level surface of safety island with high quality cement. Then, on side of traffic island, apply yellow and black road marking paint 30 cm long. After drying, traffic island is ready.
Safety Island Construction Precautions:
a) If a shelter is placed on island at same time, width should be about 150-180cm. If safety island is limited by width of road and only equipment can be placed, width should be about 40cm-80cm.
b) The length of safety island is about 500-900 cm.
c) The safety island should be 10-20 cm above ground
d) If base on which equipment is installed is a cement foundation, island can be laid directly on ground, but installation site must be laid with a steel rod (more than Φ20) in a star shape every 25 cm, and steel rod must be deep in ground and not lowered within 5 cm, set at least 5 cm.
e) If base on which equipment is installed is based on asphalt, traffic island can be laid directly on ground, but laying site must be laid with a steel rod (above Φ20) every 25cm along star. shape, and steel rod must be deep into grounde and not less than 20 centimeters, not less than 5 centimeters.
e) If equipment is installed on a ground base (the equipment is installed on side of road or next to a flower garden), a pit should be excavated on site so that safety island or foundation is more than 30 cm deep into ground.
g) Safety island and foundation materials: Portland cement 425# and medium sand produced by large factories, avoid use of earth, stones, stones, bricks and other materials.
Piping requirements and precautions:
a) There are two types of piping, open and hidden, and open pipes must be horizontal, vertical, neat and beautiful. Concealed piping requires short, smooth pipes with few bends.
b) To select a line pipe, select type and specification of pipe material according to design drawing. If there are no regulations, total area (including outer sheath) of wires passing through line pipe can be used, which does not exceed 70% of cross-sectional area inner hole of pipe. The limit is optional. When laying pipeline simultaneously with construction of building, if conditions permit, pipeline must be laid in building, and material and method of laying pipeline must be selected in accordance with specification for laying building. for laying in building, galvanized steel pipes and PVC pipes, closed metal box or closed PVC box should be used.
c) In places with strong magnetic interference, galvanized steel pipes or closed metal ducts should be used for laying and grounding.
d) PVC pipes should be used for places with acid and alkali corrosive environments and wet places, but PVC pipes are not suitable for places with high temperature, light collision and friction.
e) In order to facilitate threading and maintenance of pipe, when pipe length exceeds following values, a junction box or pull box should be installed in middle, and its position should be convenient for threading.
(1) When pipe length exceeds 40 meters and there is no bend;
(2) When length exceeds 25 meters, a bend occurs;
(3) When degree exceeds 15 meters and there are two turns;
(4) When length exceeds 10 meters and there are three turns;
f) Fixing wire pipes, fixed clamps should be added every 1.5 meters of wire pipes at corners or straight-line distances.
g) The bending radius of wire and conduit must match requirements for bending radius of cable to be inserted.
h) Pipes with trachoma, cracks and large deformation must not be used in electrical work.
i) The piping connection must be connected with a box joint or box joint.
<р>к) For verticalof well-laid pipes, depending on cross-sectional size of through wire, a junction box with a fixed thread is added every 10-20 meters, and wire is fixed in box with an insulating wire clamp. The thicker wire, shorter distance between fixed points.k) After vertical nozzle, which is not included in box (box), is inserted into wire, nozzle should be sealed.
l) The junction box must be fixed with at least three screws and closed with a cover.
m) The connection between junction box and pipe must be connected with a cup comb.
n) A junction box should be added to line pipe branch.
o) The depth of pipeline should be at least 10 cm. 5-10 cm should be opened when underground pipe enters chassis equipment
p) For buried pipes under road on which vehicles are moving, metal pipes should be used.
Wiring specifications and precautions:
1) Wiring should not only be safe and reliable, but also reasonable, neat and reliable.
2) The rated voltage of wire used must be greater than operating voltage of line, insulation of wire must be suitable for method of laying line and environmental conditions of line. The cross-sectional area of the wire must meet requirements of power supply and mechanical strength.
3) Try to avoid wired connectors when connecting. If it is not necessary to use joints, joints must be crimped or welded. Wire connections and branches must not be subjected to mechanical stress.
4) Electrical wiring in building must be horizontal or vertical. Wiring must be protected by bushings (plastic or iron water pipes matched to specifications of internal wiring), and metal hose can be used for ceiling wiring, but it must be fixed securely and beautifully.
5) A signal line cannot be parallel to a power line, let alone run in same pipe. If parallel wiring is required due to environmental restrictions, it must be more than 50 cm apart. The pipe in which signal line is located must be metal, and pipe must be well grounded.
6) The AC power supply must be laid separately and cannot be run in same pipe as signal line and low voltage DC power line. The installation of AC power line must comply with electrical installation standards.
7) The hole in pipe must be cleaned before pipe is stretched. When pulling cable, it is recommended to apply oil or talc. The cable entering pipe opening must be straight, moisture-proof and anti-corrosion measures must be taken.
8) On boththe ends of laid lines should be left with appropriate margins to facilitate maintenance and management. After laying of line is completed, line must be checked and checked for insulation and marked. Once line has been tested correctly and insulation test is correct, make a permanent mark on line. Submit laying line drawings (as-built drawings) according to actual laying conditions and note intermediate joints and joint processing methods.
2. Building Standards and Precautions for Using Earth Coil
How to make a grounded induction coil
The ground telecoil is an important part of parking management system. Its operational stability directly affects efficiency of entire system. Therefore, production of a grounding induction coil is a very important part of installation process of a project. .

(2) Use cutting machine to cut concrete floor along pen line, cutting depth is 50mm and width is 4mm. The feed slot is 7mm wide and 50mm deep.
(3) After cutting groove, rinse dirt in groove with clean water.
(4) Dry tank with a hair dryer until bottom of tank is white.
(5) Use 1.5 square meters of 32 strands of flexible wire to wind 4 or 6 turns clockwise or counterclockwise around cutting groove (6 turns for barrier, 4 turns for control machine), and lead wires should be rolled up before being released into feeder, and leave a length of 1.5-2.0 m for installation of chassis.
(6) Pour asphalt along groove and remove excess asphalt to keep pavement clean.
(7) Use a spray gun to spray cement and wire along groove to completely melt asphalt in groove.
Technical requirements
(1) Induction coil cutting groove depth ≥ 50mm, width ≥ 4mm; feed line cutting depth ≥ 50 mm, width ≥ 7 mm
(2) The number of winding turns 6 turns (barrier gate) or 4 turns (control machine), winding must be tightened into groove, lead lines must be twisted, and number of twisted turns must be at least 20 turns/meter, as as a rule, as much as possible;
(3) Solid wire without intermediate connections should be used for winding;
(4) The poured asphalt should be completely melted to make it easy to fill every gap in tank, and fix coil so that coil does not loosen and affect induction when there are cars on road.
(5) The wire must be resistant to high temperatures to prevent scalding of asphalt.
(6) After production is completed, inductance is 80-150uH.
