摘要
针对TMS320LF2407为控制器的通用变频器现场总线监控需要,设计了RS485总线和以单片机AT89C58为核心的手持式控制器。给出了所使用的RS485总线的通讯协议和通讯软件的系统化设计方法,分析了软、硬件的可靠性问题和解决方案。
A RS485 bus for linking inverters and the portable controller for monitoring inverters is described. The portable controller is based on microcomputer AT89C58 and inverters based on TMS320LF2407. The communication protocol and software-design method are also presented. Some reliability problems are discussed and solved.
