摘要： 装运、称重是水产品交易过程中一个重要环节，设计了活鱼近距离转运称重计量系统，分析和叙述了系统总体结构设计和工作原理。系统由电动提升装置、气动装卸装置和自动称重计量装置和控制装置组成。控制部分基于可编程逻辑控制器(PLC)为核心，驱动电动卷扬机和气缸分别进行活鱼提升和装卸，并依靠鱼体自重沿倾斜主滑槽输送至岸上运输车，转运至目的地。软件部分基于LabVIEW可视化平台设计了转运系统显示界面，界面具有系统通讯和数据存储操作等功能。系统应用效果表明，活鱼近距离转运称重计量系统单次传输量300 kg，转运量2 t/h，提高了活鱼转运效率，减少了大量人力，降低了活鱼的机械损伤率，提升了渔业生产机械化水平。

Abstract: Shipping and weighing are important in the process of aquatic products trading. The short distance transport weighing system of live fish was designed to analyze and explain the overall structure design and working principle. The system consists of electric lifting device, pneumatic loading and unloading device, automatic weighing and measuring device and control device. The control part is based on the programmable logic controller (PLC)to drive the electric hoist and the cylinder to lift, load and unload the live fish separately, and convey the fish to the transport vehicle on shore along the inclined chute by self-weight for transshipment to the destination. The software part, based on LabVIEW visualization platform, is designed with a transport system display interface that has the functions of system communication and data storage operation. The application effect of the system shows that the single conveying capacity of 300 kg for the short distance transport weighting system of live fish and the transport amount of 2 t/h have improved the transport efficiency of live fish, reduced a lot of manpower and the mechanical damage rate of live fish, and improved the mechanization level of fishery production.
