The invention discloses a load lifting appliance descending speed control system and method and engineering machinery, and relates to the technical field of engineering machinery. The system is applied to engineering machinery for transferring a load by using a lifting appliance, and comprises an image acquisition unit, a height identification unit and a main control unit, wherein the image acquisition unit is arranged on the engineering machinery and is used for acquiring a target image, and the target image is an image in a descending process after a lifting appliance lifts a load; the height identification unit is used for determining a target distance based on the target image, and the target distance is the height of the lower end of the load relative to the target position; the target position is the position where the load needs to be placed; the main control unit is used for adjusting the opening degree of the descending speed control valve based on the target distance. Therefore, the problems caused by the fact that a driver operates and controls the descending speed of the lifting appliance or does not control the descending speed of the lifting appliance directly are solved, automatic control over the descending speed of the load lifting appliance is achieved, the operation complexity and workload of the driver are reduced, and the service life of the lifting appliance and the service life of a container are prolonged.

    本申请公开了一种负载吊具下降速度控制系统、方法以及工程机械,涉及工程机械技术领域。该系统应用于利用吊具中转负载的工程机械,包括图像采集单元、高度识别单元和主控单元;其中,图像采集单元布置在工程机械上,用于采集目标图像,目标图像为吊具在吊取负载后下降过程中的图像;高度识别单元用于基于目标图像,确定目标距离,目标距离为负载下端相对于目标位置的高度;目标位置为负载所要放置的位置;主控单元用于基于目标距离调整下降速度控制阀的开度。从而解决了由司机操作控制吊具下降速度,或直接不控制吊具下降速度所造成的问题,实现对负载吊具下降速度的自动控制,降低了司机的操作复杂度和工作量,并提高了吊具和集装箱使用寿命。
