| Abstract: | In the industrial production process,in order to effectively monitor the concentration of harmful gases,this paper designed the DSP core gas alarm controller.The control system consists of IPC,DCS,gas alarm and control circuits,touch screen display,composed of linked devices and detectors.It uses Ethernet,CAN,485 as communication interface.Using the intrinsically safe circuit design to implement the harmful gas concentration limit,alarm and control signals are given functions.The running result shows that the system is powerful and stable performance.It can be widely used. |
