Accuracy judging method of weighing system composed of multiple electronic belt scales

Abstract

The invention discloses an accuracy judging method of a weighing system composed of multiple electronic belt scales in a blending process. A control computer carries out the steps that S1, at any moment t, the difference between the sum of the instantaneous cumulative weights of all sub scales and the instantaneous cumulative weight of a chief scale is calculated and is recorded as an instantaneous absolute deviation weight; S2, the difference between the instantaneous absolute deviation weight Y at the moment of t0 and a preset reference average value X is recorded as a deviation value Z; S3, the deviation value Z is compared with a preset deviation value interval; if the deviation value Z exceeds the preset deviation value interval, a step S41 is carried out; and otherwise, a step S42 is carried out. According to the step S41, an alarm signal is sent. According to the step S42, operation continues. According to the method provided by the invention, the accuracy of the electronic belt scales can be judged in real time, and the stability of the quality of production process is improved.

Description

technical field [0001] The invention relates to the field of tobacco processing, in particular to a method for judging the accuracy of a weighing system composed of a plurality of electronic belt scales in a blending process, and can be applied to processes such as blending and flavoring shredded tobacco. Background technique [0002] The electronic belt scale is the most widely used belt scale, which is composed of a load-bearing device, a load cell, a speed sensor and a display. When weighing, the load-bearing device transmits the gravity of the material on the belt to the load cell, and the load cell outputs a voltage (mV) signal proportional to the gravity of the material, which is amplified by the amplifier and sent to the analog / digital converter to become a digital quantity A, sent to the calculator (the calculator can be located in the controller that comes with the electronic belt scale, or it can be located in another controller); the speed sensor is located on the...
