With the rapid development of China's economic construction, agricultural mechanization, unmanned, information has also entered the rapid development of the growth period. Based on emerging information technologies such as the Internet of Things and cloud computing, we will vigorously develop digital agriculture and smart agriculture, and deeply integrate information technology with agronomic technology, agricultural environment, agricultural management and agricultural production, and agricultural informatization has entered a new stage of development. China has also introduced a series of policies to support agriculture and benefit agriculture, indicating that the state attaches importance to, supports and protects agricultural mechanization and agricultural information technology, which has injected a strong impetus to accelerate the development of agricultural mechanization, and the development of agricultural mechanization and agricultural machinery information technology in China has taken an important turn. It is possible to establish a multi-level and human-machine integrated agricultural mechanization information system based on computer technology, 3S technology and communication technology as the main means, and the Internet of Things and cloud computing as the auxiliary, which is conducive to the information sharing of agricultural production management departments, can provide accurate information in a timely and effective manner, and provide macro-decision-making services for the government to regulate the market and rural economic development. It has guided the agricultural machinery management departments and related agricultural production departments at all levels, and is an important measure and means to guide the healthy development of agricultural mechanization. At the same time, it will also promote the development of agricultural machinery production, management and service activities. In addition, the development of agricultural mechanization information business will also promote the development of agricultural economy and the construction of new industries. Using modern information technology, establishing and improving the service management function and decision support system of the intelligent agricultural machinery integrated management platform has very important theoretical and practical significance for strengthening the macro-control and micro-guidance of agricultural machinery informatization, and further promoting the development of unmanned agriculture and informatization.
