HUMAN FACTORS OF THE OPERATOR'S WORK-ABILITY AFFECTED BY AUTOMATIC SYSTEM OF FARM MACHINERY

由于农业机械的自动化或机器人技术旨在创造高输出工作能力并降低作物生产成本，因此在大粗糙不平的田地中以非常高的速度进行农业工作。在系统上，操作人员与机器进行交互，例如查看现场的工作结果或机器的信息显示，以决定更好的性能操作，以及操作机器的几个控制。使操作者在高速工作状态下能迅速地观察、决策和操纵机器，操作者视野的离散率应与操作者的损伤或感觉疲劳有关。“眼标记录仪”可用于测量车辆驾驶员的视点离散度。但由于仪器本身的红外辐射受到太阳辐射的干扰，不能在室外工作。然后，一个小型摄像机和记录仪是有用的，以测量农具操作员在露天分散。自动化农业机械作业的视点离散度的结果表明，在良好的条件下，操作者在自己的内部进行操作，但在恶劣的条件下，他不能保持伤害或感官的宽容。在农业工作承包商，他们的机器每天高速运行的操作员，座椅的持续振动是一个大问题，原因有三：研究结果表明，随着自动化机械的发展，工作环境越来越差，因此，对自动化机械的人机工程学或人机关系的研究是今后发展的迫切需要。

As the automation or robotics for farm machinery takes aim to create high-output work ability and to depress the crop production cost, the farm-work use with them are conducted on very high speed at the large asperity, uneven field. On the system, the operating person interacting with the machine, such as to view the work result at field or information display of the machine, to decide better performance operation, and to operate several controls of the machine. So that the operator is enforced quickly view, decision and handling the machine in the high-speed work condition.The rate of point dispersion of the operator's view should be related to the hurt or sensuous fatigue of the operator. The 'eye mark recorder' was useful to measure the view point dispersion of vehicle operator. But the instrument can not work in open air, because of the infrared radiation of it is deranged by solar radiation. Then a small video camera and recorder was useful to measure the dispersion of farm implement operator in the open air. The result of the view point dispersion of automated farm machinery work shows that the operator conducts within himself on good condition, but on bad condition he could not keep hurt or sensuous allowance.At the farm work contracto, the operators of their machine which run high speed work every day, the continuous vibration of seat is big problem for three reasons : people don't like it, it damages his body and it has bad effect on working efficiency.The results of studies shows that the work condition with the automated machinery turn of the situation for the worse, so that the ergonomics or man-machine studies of them are emergent necessary study for future advance.
