Debugging device based on high-speed serial port of thermal power plant and use method

Abstract

The invention discloses an external debugging device based on a high-speed serial port of a thermal power plant and a use method, the device comprises an embedded central processor, a memory, a network card, a memory, an FPGA and a high-speed serial port, the memory, the network card and the memory are all connected with the embedded central processor, and the embedded central processor and the high-speed serial port are both connected with the FPGA. According to the device, the FPGA is arranged and used for collecting serial port data, it is guaranteed that on the premise that the serial port communication rate is not reduced, communication data of the thermal power plant controller and an IO part can be intercepted in real time, and the actual communication state of the thermal power plant controller and the IO part is not affected. According to the invention, the embedded central processing unit realizes the function of high-speed serial port data debugging and packet capturing between the controller and the IO part.

Description

technical field [0001] The invention belongs to the technical field of DCS transmission data processing, and in particular relates to a debugging device based on a thermal power plant high-speed serial port and a using method. Background technique [0002] Since the thermal power DCS control system has adopted a communication scheme with a maximum rate of 5Mbps between the controller and the IO, and the RS232 rate of the commonly used notebook computer can only support up to 115200Kpbs, so the data transmitted by the serial port can only be reflected by the oscilloscope at present. Regardless of the ease of use during debugging, the convenience of data display, and the convenience of debugging, it is very troublesome, and there are the following problems: 1) The communication rate of the serial port of the existing upper computer cannot meet the debugging requirements of the high-speed serial port directly; 2) It is impossible to intuitively monitor and conveniently find ...
