摘要
提出基于多串口卡实现低成本的中波发射机通用实时监控方案;基于Windows API实现了多串口卡数据收发模块,并将中波发射机所需采集的模拟量、状态量以及执行命令分成实时数据和非实时数据两类,对这两类数据采用不同的采集频次,实现用户对实时数据监控的要求;对各发射机设备进行数据采集时采用了统一发送-流水接收的处理方式,即统一地给各发射机发送数据采集命令,而以流水的方式依次处理接收数据,提高数据采集的效率;监控系统在Delphi7.0+SQL2000平台下实现,实际运行表明,该监控方案是有效的。
A common monitoring and controlling system scheme is presented. The program module of Receiving and sending data is implemented through Widows API. All sampled data and control commands are divided into two classes： realtime data and nonrealtime data. Different sampling frequencies are used in data sampling in order to monitor rapid realtime data. Data sampling mode of uniform serial sending and streamy receiving is used, which makes data sampling efficency be enhanced. The system which is based on DelphiT. 0＋SQL2000, is developed and has most functions which are raised by many users. It has been put into practice. It shows that the scheme is feasible and validate.
