Abstract本发明公开一种用于基金会现场总线的减少总线通信量的控制结构,它包括两个设备,其中设备1中包含一个模拟量输入功能块,与传感器相连;设备2中包含控制功能块、模拟量输出功能块,所述模拟量输出功能块与执行器相连;在设备1中,增加一个预测控制功能块和一个控制功能块,其中控制功能块的参数与设备2中控制功能块的参数完全一样;在设备2中增设一个与设备1中的预测功能块完全相同的预测功能块;使用通用的组态软件配置设备1和设备2中各个功能块之间参数连接。本发明能减少总线网络通信负担,从而提高总线网络数据通信的实时性和确定性;并对错误的采样数据报警,起到第二传感器的作用,提高控制系统稳定性。
Other AbstractThe control structure includes two pieces of equipment. The first equipment includes one analog amount input module connected to the sensor and the second equipment includes control module, analog amount output module connected to the executor. The first equipment has one increased prediction control module and one control module with the same parameters as that in the second equipment and the second equipment has also one increased prediction control module the same as that in the first equipment. Universal configuration software is used in configuring the parameter connection of the modules in the first equipment and the second equipment. The present invention reduces the bus network communication load to raise the real-time property and determinacy of bus network in data communication. The present invention also warns the error sampling data, acting as the second sensor to raise the stability of the control system.
