Causes and Solutions of Unstable Communication in Parking System
The main issue with the current system is unstable communication, characterized by intermittent connectivity. Below, I have summarized the reasons identified by the parking system maintenance team, along with suggested solutions for each problem.
1. **Reason**: The communication lines are long and not properly wired. Standard power cables or unshielded twisted pair cables are often used, and connectors in the middle may not be securely connected. This is a common cause of instability.
**Solution**: Replace the communication cables with proper shielded twisted pair cables. If site conditions limit this, you can add a 120Ω termination resistor or install an RS-485 repeater to improve signal stability.
2. **Reason**: The RS-485 communication converter has poor load capacity. This is also a frequently encountered problem.
**Solution**: Replace the RS-485 converter. If there are many devices in the system, consider adding one to four additional RS-485 converters to handle the increased load and improve reliability.
3. **Reason**: The computer's serial port or the RS-485 converter is unstable. This is less common but still possible.
**Solution**: Replace the RS-485 converter. If the issue persists, consider installing a serial expansion card on the computer or replacing the computer altogether. Avoid using USB-to-serial adapters, as they can introduce additional instability.
4. **Reason**: The communication circuit on the control board is unstable. This is a less frequent issue.
**Solution**: Inspect the control board for any faults. If necessary, replace the board to restore stable communication.
In addition to these technical fixes, it's important to ensure that all cabling is properly installed and maintained. Regular checks and updates can prevent future issues. It’s also recommended to use high-quality components and follow industry standards when setting up or upgrading the system. By addressing these factors, the overall communication stability of the parking system can be significantly improved.
