Tank field monitoring and early warning mainframe and monitoring and early warning method thereof

The invention relates to a tank field monitoring and early warning mainframe and a monitoring and early warning method of the tank field monitoring and early warning mainframe, and belongs to the field of safety production monitoring. The mainframe comprises a mainframe case, a safety parameter processing circuit board, a video processing circuit board, a safety parameter input and output interface board, a video input and output interface board, a computer power supply and an SATA hard disk, and further comprises a liquid crystal screen embedded in the upper panel of the mainframe case, a liquid displayer, a mouse and a keyboard. The safety parameter processing circuit board, the video processing circuit board, the safety parameter input and output interface board, the video input and output interface board, the computer power supply and the SATA hark disk are arranged in the mainframe case. The liquid crystal displayer, the mouse and the keyboard are connected with the mainframe. The method includes the step of collection, display and storage of safety parameters and videos of a tank field, the step of storage tank liquid level over-limit alarm and safety interlock control, the step of oil transportation pump house combustible gas over-limit alarm and safety interlock control, and the step of storage tank temperature and tank field combustible gas concentration over-limit alarm. According to the tank field monitoring and early warning mainframe and the monitoring and early warning method of the tank field monitoring and early warning mainframe, the function of multipath parameter collection and the function of multipath video collection are integrated, and therefore the function of collecting and processing on-site safety parameters and images in a centralized mode, the function of linkage alarm, the function of network remote transmission, the function of safety interlock control and other functions are achieved. The tank field monitoring and early warning mainframe and the monitoring and early warning method of the tank field monitoring and early warning mainframe have the advantages of having the oil tank field safety monitoring seamless integration function and being high in cost-performance ratio.
