摘要
电力SCADA(Supervisory Control and Data Acquisition监测控制)系统是电力调度生产指挥的核心技术支持系统,而前置系统又是电力SCADA系统的前端,是连接RTU与主站服务器的纽带,担任着上传下达的重要角色,主要负责整个系统所需数据的采集工作。前置机的主要任务有:通过收集并处理RTU经通道传送的报文,将数据提供给其它相关应用;接受调度员给RTU的命令并下发报文到相应的通道;维护RTU、通道、主备机的状态;转发数据给其它系统。
Electric power SCADA system was the core technology support system of electric power dispatching production command. But the front-end system was at the front of SCADA system and it was the bond between RTU,the main server. As the important role of transmission, it was responsible for the required data collection in the whole system. The main task of front -end processor were providing the data to other applica-tions which was collected and dealt with the messages from RTU;accepting the orders of the RTU from the dispatcher and isstting messages to the corresponding channels;maintaining the conditions of RTU, channel and main standby and forwarding data to other systems.
