企业电能管理系统的通信研究

Research on Enterprise Energy Management System's Communication

通信层是企业电能管理系统必不可少的组成部分,本项目采用TI公司的TMS320F2812 DSP作为通信终端主芯片,传输网采用RS485总线手拉手布网并采用广播应答通信方式,设计电路板和布网时应用抗干扰技术保证通信质量,考虑到未来系统的发展选用Modbus通信规约方便日后与外界相连网。

Communication layer is the necessary part of the enterprise energy management system,This project uses the TI＇s TMS320F2812 DSP as the communication terminal＇s main chip.Transmission network use RS485 hand in hand bus network and Broadcast Communications.Using Anti-jamming technology in PCB and network to ensure the communication quality and choose Modbus communication protocol for the future networking.
