摘要
针对大坝现场自然条件恶劣的特点 ,设计了基于PLC的分布式数据采集系统 ,相对于单片机系统 ,具有可扩展性好 ,可靠性高 ,抗干扰能力强等优点。使用VC + + 6 .0实现PLC和上位机的通讯 ,对于现场PLC供电的特殊要求 ,设计了后备电源解决方案 ,并进行了实际应用。
Presents a PLC based distributed monitoring system on a dam that can run in very bad nature condition.The system has strongpoints such as high reliability,high expensibility and anti-jamming.The paper introduces a method of communication between super-computer and OMRON C200HE with VC++6.0 and designs a power supply in support for a special require.
