摘要
随着国家对大型发电厂的管控力度加强,对需要管控的数据种类增多,数据协议的种类也增多,同时人们追求"利益最大化",这就出现了多对一协议转换的瓶颈。针对这种情况,对现有的协议转换模式进行改进,将传统的"一对一"传输模式改进为"多对一"模式,从而有效地避免"信息堵塞"问题,同时引入单片机操作平台,在软硬件上实现多协议数据采集网关。软件上采用的消息机制将通道选择、协议转换、网关参数设置以及检测等功能有机地组合成一个完整的系统,便于统一调度,有效地提高了协议转换的效率和实时性,并且由于使用51系列单片机完成协议转换网关,所以也降低了设计成本。
With the control strengthen of large power plants,and increase of controlled data category and data protocol category,the benefit maximization is pursued,which leads to a bottleneck for many-to-one protocol conversion.Therefore,the available protocol conversion mode is improved,and the traditional"one-to-one"transmission mode is improved as the"many-to-one"mode to avoid"message blocking".The single chip microcomputer(SCM)operation platform is introduced.A multi-protocol data acquisition gateway is implemented on software and hardware.The message mechanism is used in software to combine the functions of channel selection,protocol conversion,gateway parameter setting and detection into a complete system,which is convenient for uniform scheduling,and can improve the efficiency and real-time performance of protocol conversion effectively.The51serial SCM is used to complete the protocol conversion gateway,which can reduce the design cost.
