Checking method of subsidiary electronic belt scale

Abstract

The invention discloses a checking method of a subsidiary electronic belt scale. The checking method comprises the following steps: step 1) recording a material flow A1 of a total electronic belt scale; step 2) adjusting the material flow of a subsidiary electronic belt scale, wherein the adjusting volume is A2; step 3) recording a new material flow A3 of the total electronic belt scale after the electronic belt scale works for a certain time period T1; step 4) substituting A1, A2 and A3 into a calculation formula as follow: checking parameter alpha=(A1-A3) / A2, and figuring out alpha; and step 5) comparing alpha with an error limit value B1, and obtaining the checking result. According to the checking method of the subsidiary electronic belt scale provided by the invention, the total electronic belt scale is adopted to check the subsidiary electronic belt scale; and in the whole checking process, the operation of automatic burdening production line is unnecessary to be stopped, the synchronous operation of production and checking is realized, and the scale is checked by the scale in the same standard, so that the checking precision is high.

Description

technical field [0001] The invention relates to the technical field of checking electronic belt scales, in particular to a checking method for electronic belt scales. Background technique [0002] Electronic belt scale is a kind of measurement facility widely used in automatic batching production lines in metallurgy, mining and other production fields at present, including total electronic belt scale and multiple electronic belt scales connected with the total electronic belt scale, and used in conjunction with the total electronic belt scale The main belt is the total belt, and the sub-belt is used in conjunction with the electronic sub-belt scale. The material flow on the total belt is equal to the sum of the material flow on all sub-belts. Influenced by factors such as attachment and installation deviation, there is a certain fluctuation in operation, which leads to distortion of measurement data and restricts the work quality of the automatic batching production line.

[0002] Electronic belt scale is a kind of measurement facility widely used in automatic batching production lines in metallurgy, mining and other production fields at present, including total electronic belt scale and multiple electronic belt scales connected with the total electronic belt scale, and used in conjunction with the total electronic belt scale The main belt is the total belt, and the sub-belt is used in conjunction with the electronic sub-belt scale. The material flow on the total belt is equal to the sum of the material flow on all sub-belts. Influenced by factors such as attachment and installation deviation, there are certain fluctuations in operation, resulting in distortion of measurement data, which restricts the work quality of the automatic batching production line. In order to ensure the accuracy of the measurement data of the sub-electronic belt scale, it must be checked regularly

[0003] At present, the verification methods of general-purpose electronic belt scales mainly include: hanging code calibration scale, chain code calibration scale and physical calibration scale, etc. These calibration methods need to stop the production line before they can be carried out. Reduced operating rate

[0004] It also includes the method of prolonging the checking cycle. Although it has a certain slowing effect on the reduction in the operating rate of the automatic batching production line, it cannot completely prevent the reduction in the operating rate of the automatic batching production line. Production and checking still cannot run synchronously. Due to the extension of the calibration cycle, the work quality of the automatic batching production line will also be affected
