Abstract: Agricultural development is inseparable from agricultural machinery, in order to meet the automation and excellent performance of agricultural machinery, various technologies emerge in an endless stream, among which there is copying technology. Copying technology plays an important role in the stability, accuracy and operation effect of agricultural machinery in operation, and also plays a key role in the optimization of agricultural machinery. This paper analyzes the application of copying technology in China at present, divides the copying technology applied to agricultural tools into active copying and passive copying, and summarizes the advantages and disadvantages of the two copying technologies. Passive copying technology has low cost, is generally pure mechanical copying, simple structure and easy maintenance, but is greatly affected by the ground environment, the accuracy and sensitivity are not high. The level of active copying technology is relatively higher, and generally requires electrical and hydraulic cooperation, with high copying accuracy and stability, but the cost is higher and the field of agricultural machinery has not been widely promoted. Due to the complex and changeable field environment, the lag problem of copying technology still exists in the current, the sensor effect is relatively general, and relatively difficult to control and other problems are still urgently needed to solve, although copying technology has been developed in the field of agricultural machinery, but there is still a long way to go in order to realize the intelligent and simple copying technology. With the addition of precision technology, copying technology is developing steadily towards a more intelligent and easy direction.
