Information fusion technology in gate control system

JK卷扬机启重设备智能控制系统由于其核心控制器即西门子S7-200PLC可直接获取从传感器采集到的编码信号、电量信号等,从而具有开度荷重测控准确、多重保护快速,使用范围广等优点。为了进行深入研究,进一步提高测控精度,更好地保护系统,基于Modbus信息融合技术,以STC12C5616AD单片机为核心设计了一个信息转换器,把SSI角编码器的编码值、压力传感器的压力信号和DS18B20温度传感器的温度信号等信息融合到系统中,为闸门的测控精度和安全运行提供保证。实验表明:本转换器可以实时采集1路角编码器的编码值、3路压力传感器的压力信号和2路温度信号等重要数据,并融合到JK卷扬机启重设备智能控制系统中。

Intelligent control system of JK hoist lifting equipment has many advantages such as accurate measurement and control of open degree and load,quick multi-protection,widely use and so on,because of its core controller,Siemens S7–200PLC can directly obtain the code signal,electric power signal from the sensors.In order to make depth study,to further enhance the control precision,give the system more protection,a information converter is designed in this paper which is based on the information fusion technology of Modbus and takes the STC12C5616AD single chip microcontroller as the core.The SSI encoder＇s code value,pressure sensor＇s pressure signal,temperature signal of temperature sensor DS18B20 and other information are integrated into the system,thus the guarantee for gate＇s control precision and safe operation is provided.Experiments show that 1-way encoder＇s code value,3-way pressure sensor＇s pressure signal and 2-channel temperature signal and other important data are instantly gathered by this converter,and integrated into JK hoist heavy equipment intelligent control system.
