The invention provides a mechanical operation evaluation method based on the Internet of Things, and the method comprises the following steps of S1, carrying out data collection on the surrounding environment for mechanical operation through an environment data collection terminal, and importing the data into a data processing module; and S2, collecting data via a mechanical data acquisition terminal. According to the mechanical operation evaluation method based on the Internet of Things, an agricultural operation mechanical development level evaluation index system is established through a cloud server, the mechanical development level evaluation index parameters in each grid unit are obtained through the spatial interpolation calculation, evaluation content is obtained through the processing of the data processing module; the collection and detection content is wide, data are comprehensive, various information, such as agricultural product production quality, etc., can be reflected, the mechanical operation content is comprehensively evaluated, a measurement method is simplified, and the data processing efficiency is improved; the informatization technologies, such as the Internet, the Internet of Things, big data, etc., are effectively applied to the agricultural machinery operation services.
