中文摘要：

ECU是工程机械电控系统的核心部件,目前国内中高端ECU市场基本被国外厂商所垄断.设计了一款基于XC2287M微控制器的工程机械智能ECU,采用CODESYS软PLC作为编程平台,支持IEC 61131-3定义的5种标准PLC语言进行编程.所设计的ECU拥有丰富的I/0资源和完善的安全保护机制,能够广泛应用于各种工程机械控制系统,打破国外厂商对ECU市场的垄断.

英文摘要：

ECU is a core component of the control system for construction machinery,and the curTent domestic market of ECU is almost monopolized by foreign manufacturers.This paper introduces the design of an intelligent ECU based on XC2287M micro controller,using CODESYS Soft-PLC which supports five IEC 61131-3 defined PLC languages as the programming platform.The designed ECU has highly multiplexed input and out modules and rich I/O resources,providing sufficient safety protection mechanisms.It can be widely used in a variety of control systems,breaking the monopoly of foreign manufacturers on ECU market.
