摘要
结合污水处理过程的特殊环境和控制特点,介绍了CAN总线的优点,特别是相对于已被广泛采用的RS-485总线的优势。分析了在大型污水处理厂控制系统中,将CAN总线应用于局部控制子系统中的实施方案,介绍了两种将现有RS-485总线升级为CAN总线的低成本解决方案。
Combined with the special circumstance and control characteristics of wastewater treatment process, many advantages of CAN-bus are introduced, especially the advantages of RS-485 which has been used widely. The application of CAN-bus in local control subsystem of large wastewater treat- ment plant control system is analyzed. Two low cost solutions to upgrade existing RS-485 to CAN-bus are proposed.
