Intelligent parking system wiring installation precautions 1, power:
Ensure that the power is sufficient and try to use a linear power supply. Install the power supply as close as possible to the consumer to avoid interference and transmission loss.
2, wiring:
It is divided into power line, communication line and signal line. When wiring, pay attention to strong and weak power separately. The distance between the two tubes is greater than 20cm.
Power cord: The wire diameter is thick enough to use multiple strands of wire.
Signal line and communication line: shielded five types of twisted pair. The 485 bus must use a pair of twisted pairs of wires to connect A+, A-. It is recommended to use a 4*0.5 four-core shielded cable when purchasing the wire.
Note the following:
· Shielded wires must not be used as 0V voltage (power ground) connection wires. · Each shielded circuit can only have one ground terminal. · When the shielded loop cannot be grounded, connect the shielded cable to another shielded loop of the network. .
• The signal ground of each module must be connected together.
· If there is a breakpoint in the middle of the line, the breakpoint should be soldered with a soldering iron and insulated.
• Do not put the network cable and AC power together.
