Intelligent parking lot system communication failure analysis

2022-04-21 00:00:00

Communication failures is every intelligent parking lot may encounter problems, here we communication failures do a summary to the parking lot system, may be in need of help to you.Summarised here, however, is the communication failures by RS485 communication parking lot system, or other USES, such as TCP/IP communication CAN bus communication methods in the parking lot is not applicable, this indicate the first.

fault description: communication and starts, is not stable, often read the card, the phenomenon such as control and downs.

the reason one: non-standard wire wiring caused.Bad communication wire, communication route distance, construction layout is not standard, poor contact reasons, these reasons are wire cabling may lead to communication failures.

the solution: replace the inferior wire, check the communication distance is reasonable, if you can’t change, you can add 120 & Omega;Resistor, or add a RS485 repeater,

the reason two: RS - 485 converter load capacity difference lead to communication failures.

the solution: replace the RS485 converter.

three reasons: to control the serial port on the computer or RS485 communication is not stable.

solution: a computer installed a serial port expansion card or change of RS485 converter.


why 4: control the mainboard.

the solution: this kind of problem can only be looking for a manufacturer, please come to replace the motherboard test professionals.

intelligent parking lot communication failures in general is above four reasons, ruled out one by one, should be can solve.Ok, we will introduce to this, thank you for reading.(starting: http://www.nthuanlicn)
