Abstract：In order to improve the debugging and fault monitoring and analysis capabilities of inverter

products，the design scheme of network version process data acquisition and analysis software was proposed.The

composition and implementation of the software system were discussed，and the technical means such as multithread，virtual memory，drawing class library and high-speed fiber synchronization were proposed to solve the technical problems of system operation. The field application of this software system shows that the system runs

stably，has the characteristics of low cost，multi-channel transmission，low sampling period，high data accuracy，rich graphics functions，and strong scalability.
