摘要: 农业的发展离不开农机,为满足农用机械自动化及优良的作业性能,各类技术层出不穷,其中就有仿形技术。仿形技术对农用机械在作业时的稳定性、准确性和作业效果等各方面起到重要作用,同时也对农机的优化起到关键作用。本文对现阶段国内仿形技术的应用进行分析,将应用到农用机械上的仿形技术分为主动仿形技术和被动仿形技术两大类,同时总结归纳两种仿形技术各自的优缺点。被动仿形技术成本较低,一般为纯机械仿形,结构简单且容易检修,但受地面环境影响较大,精确度和灵敏度都不高。主动仿形技术水平要求较高,一般需要电、液配合工作,仿形精度及稳定性都较高,但成本较高而且农用机械领域还没有大范围推广。由于田间环境复杂多变,目前仿形技术中的滞后问题依然存在、传感效果比较一般以及调控起来还相对困难等问题仍然急需解决。随着精尖技术的加入,仿形技术正在朝着更加智能化、简易化的方向稳步发展。

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.
