Abstract: As a result of critical industrial conditions of Electrostatic Precipitator(ESP), ESP controller requires a network communication 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.
