工程机械仅仅具有放大人的体力的功能是不够的,还需要以现代科技提升工程机械的“智慧”能力,以减轻和替代人的智力劳动。为此就需要工程机械对复杂的作业具有感知能力,在此基础上,根据某种控制策略通过合适的执行装置自动调节,使工程机械有“意识”地适应外部环境的变化,实现这一功能的一个重要环节便是传感器。
It is not enough for a construction machinery to have only the function of amplifying a person’s physical strength. It is also necessary to upgrade the “wisdom” ability of construction machinery with modern science and technology so as to reduce and replace people’s intellectual work. To do this, it is necessary for construction machinery to have the ability to sense complex operations. On the basis of this, it is automatically adjusted according to a certain control strategy through suitable actuators to make the construction machinery adapt to the changes of the external environment “consciously” to realize this function An important part of the sensor is the sensor.
