Abstract

The invention discloses a two-dimension angle-variable electronic belt scale weighing compensation method and system. The method includes: utilizing a method that cosine values of positive and negative angles are equal to acquire a datum offset angle; calculating compensation accumulation quantity Q according to the datum offset angle and angles between Y and Z directions and a horizontal straight line to correct compensation angle offset caused by actual stressed structure state of a scale frame for compensation. By the method, compensation accuracy is improved greatly. The system is characterized in that a load sensor, a speed sensor, a Z-direction angle sensor and a Y-direction angle sensor are all fixedly mounted on the electronic belt scale frame and all connected with a two-dimension angle-variable belt scale instrument. The problem of metering errors caused by changing of two-dimension inclination angle of an angle-variable electronic belt scale in the process of metering is solved effectively, and application range is wide.

Description

technical field [0001] The invention relates to a compensation method and system, in particular to a two-dimensional variable-angle electronic belt scale weighing compensation method and system. Background technique [0002] The variable-angle electronic belt scale is a kind of measuring equipment for continuous and automatic weighing of materials during the transportation of various ore, coal, coke, sand and other solid materials. It is characterized by the Y direction and The angle in the Z direction is constantly changing, which requires that the variable-angle electronic belt scale must be able to ensure accurate measurement even when the angle changes. However, conventional electronic belt scales are very sensitive to angle changes. It has been proved by experiments that an angle change of 10° will produce an error of more than 1.5%. Scales are not allowed. Therefore, conventional electronic belt scales cannot measure accurately in such an environment. Contents of t...
