Abstract

A signal processing method for an electronic belt scale, which relates to an electronic belt scale and solves the problem of inconvenient maintenance of a traditional belt scale by a structure of a belt scale body and a calculator. The belt scale adopts the existing belt scale body, and the signal processing adopts PLC or DCS, the signal processing method includes: measuring the load rate of the weighing roller installed with the load cell; measuring the speed of the load belt; measuring the real-time flow value of the material. PLC or DCS can calculate other weighing-related values ​​based on these three measured value data. The present invention is suitable for matching use with most electronic belt scale bodies currently available in the market, increases the flexibility of use of the electronic belt scale, and facilitates maintenance.

Description

technical field [0001] The invention relates to an electronic belt scale, in particular to a signal processing method of the electronic belt scale. Background technique [0002] The belt scale is a kind of continuous material flow measurement equipment designed by the principle of gravity weighing, which is suitable for the measurement of non-viscous materials such as powder, granular and small pieces in the industries of building materials, metallurgy, chemical industry and food. And flow control, it has the advantages of high reliability, wide application range, low installation height requirement, large measurable flow range and no need for special feeding equipment. [0003] The principle of the electronic belt scale is that when the material to be weighed passes through the weighing section of the belt scale, the weighing sensor on the measuring stick detects its weight (kg / m). In addition, the speed detection installed on the belt The sensor detects the linear speed (...
