Abstract

The invention relates to a monitoring system and method for the operating state of an electronic belt scale, the electronic belt scale and a tobacco processing system. The monitoring system comprisesa ratio calculating module (10) and a comparative judgment module (20), wherein the ratio calculating module (10) is used for calculating a ratio of instantaneous flow rate of material conveying of the electronic belt scale to working frequency of a frequency converter; the comparative judgment module (20) is used for judging whether the ratio of the instantaneous flow rate to the working frequency exceeds a preset range, and if the ratio exceeds the preset range, failure of the electronic belt scale is determined. The monitoring system can judge whether the electronic belt scale fails by monitoring the ratio of the instantaneous flow rate to the working frequency, so that the electronic belt scale can convey and weigh materials normally, weighing accuracy and precision of the electronic belt scale are guaranteed, and the product quality is improved.

Description

technical field [0001] The invention relates to the technical field of tobacco processing, in particular to an electronic belt scale operating state monitoring system and method, an electronic belt scale and a tobacco processing system. Background technique [0002] In the process of tobacco processing, tobacco leaves need to be accurately weighed in multiple steps such as leaf moistening and feeding process, shred drying process and flavoring process. At present, electronic belt scales are generally used for weighing tobacco leaves. [0003] The electronic belt scale is equipped with a load cell and a rotary encoder, and can also be equipped with a separate PLC control system. Among them, the load cell is used to detect the weight of the tobacco leaves, and the rotary encoder is used to detect the running speed of the belt. After the PLC control system receives the weight signal from the load cell and the speed signal detected by the rotary encoder, it calculates through th...
