摘　　要：高压静电除尘(ESP)电场中苛刻的工业应用需求对工业控制器的网络通信模块提出了较高的要求,控制器在必须具备较高的信号处理能力的同时,也要满足网络通信的实时性和开放性要求。基于AM1808实现的网络通信模块,采用CY7C024AV2双端口存储器实现核间通信,有效解决控制器内部核间大数据量实时高速传递的问题。基于该通信模块可让控制器实现多级互联。网络通信模块采用MODBUS/TCP通信协议建立控制器网络,利用控制协议层的开放性提高上层应用的兼容性。基于AM1808的网络通信模块方案经过电场实验测试,实验表现良好。As a result of critical industrial conditions of Electrostatic Precipitator（ESP）, ESP controller requires a network com- munication module which can meet a higher level requirement. An excellent signal processing ability, as long as real-time and open communication features, are necessary for ESP controller. This paper presents a network module based on AM1808. This module takes CY7C024AV2, a dual port memory, as the way to make Inter-processor Communication （IPC） possible, so that large amount of data can be exchange efficiently. With this network module, ESP controllers can be connected together to make a multi-controller ESP system. And to make it compactable with upper applications, this network module takes MODBUS/TCP as the key protocol for network communications. After the electrostatic field experimental test, this network module based on AM1808 can achieve a good performance.
