Abstract:

There are several important links in live fish transportation, among which, transferring fish body from water to long-distance transport vehicle would directly affect fish survival rate and economic benefits. During live fish transportation, the measurement process was cumbersome and time consuming. It was also hard to change and retrieve the data. In order to solve these problems, an automatic measurement system with 3 sigma statistical principle and concept of software filter was designed to control the mechanical device directly, implement software filter and move average treatment to the data transmitted from electronic scale. The data with statistical and query functions was stored in database. The system could monitor the whole process of transshipment. Final results showed that after using this system, the labor costs was reduced to 28%, transport time decreased averagely to 50%, and weighing error was controlled within 0.5%. The automatic reform effect was remarkable and users satisfactory level was high.
