Quickness and precision are the important properties which are required for an industrial scale used in production lines.
Remarkable progress of a microcomputer makes new approaches possible to meet the two contradictory requirements, and the approaches are realized through a set of softwares.
In this paper, we show“Dynamic Mass-measurement System of Displacement and Velocity Sensing Type”(DMS-DV), one of the best results of the new approaches, which consists of a spring scale, a microcomputer, and the displacement and velocity sensors. Then the software executed on the microcomputer plays an important role in the system.
The operation of the system is the following. Firstly, goods are put on the goods-plate of the spring scale, and the goods-plate is oscillated. Secondly, data of the displacement and velocity of the oscillation are processed in real-time by means of the software, and the mass of the goods is thus calculated.
In the data processing, the Practical DV-Algorithm is used, which is based on the idea of the dynamic measurement method. The special feature of the idea lies in the positive utilization of the dynamics of a measuring system.
The test system of the DMS-DV has been built up to examine the total performance and the real characteristic of the DMS-DV, though the feasibility of the practical DV-Algorithm was already verified by the computer simulation study.
The test system is a crude construction in comparison to industrial systems. However, the data obtained on the system are enough to verify the feasibility of the DMS-DV in a practical sense.
