Intelligent agricultural machinery equipment is a complex of informatization, automation, and intelligence. Its intelligence level is mainly reflected in the application of advanced technologies such as state perception, data analysis, scientific decision-making, and autonomous control in the operation process. At present, there are mainly problems in the operational services of agricultural machinery equipment in China, such as poor practicality of fault automatic monitoring, imbalanced allocation of maintenance service resources, and high service scheduling costs. The current situation and characteristics of typical technologies related to the operation and maintenance service management of combine harvester at home and abroad were summarized, and focusing on the research status and development trends of remote operation and maintenance service platform for agricultural machinery equipment, operation data monitoring, multi machine collaborative operation, and operation and maintenance service optimization. Firstly, the overall architecture and technological progress of the operation and maintenance service management platform were elaborated. Then the research progress of remote operation and maintenance data monitoring technologies such as operating conditions, job quality perception, and vehicle terminal management was elaborated, as well as the research progress of multi machine collaborative operation technologies such as path planning, collaborative control, and task allocation. The research progress of operation and maintenance service optimization technologies such as fault diagnosis prediction, maintenance strategy, and group scheduling was also elaborated. Finally, combined with practical application scenarios, the challenges and opportunities faced by agricultural machinery equipment operation and maintenance service management technology were summarized and analyzed, and the future development direction of agricultural machinery equipment information management technology was proposed. Future research directions for informationization of agricultural equipment operation and maintenance service management in China were pointed out.
