A high-accuracy real-time monitoring method for electronic belt scales

Abstract

The invention belongs to the technical field of weight measurement of materials in the transmission state, and in particular relates to a high-accuracy real-time monitoring method for electronic belt scales. Two electronic belt scales are installed in series on the same belt conveyor, respectively being the first electronic belt scale. The scale and the second electronic belt scale realize simultaneous measurement. The first electronic belt scale is connected to the first on-site signal acquisition unit, the second electronic belt scale is connected to the second on-site signal acquisition unit, and the first on-site signal acquisition unit is connected to the second on-site signal acquisition unit. The signal acquisition unit is connected to a terminal processor at the same time, and the terminal processor is connected to the alarm device through the controller.

Description

technical field [0001] The invention belongs to the technical field of weight measurement of materials in a transmission state, and in particular relates to a high-accuracy real-time monitoring method of an electronic belt scale. Background technique [0002] As a measuring device for bulk materials conveyed by belts, electronic belt scales are being used more and more widely, and their application acceptance is also greatly improved. The measurement principle of the electronic belt scale is to install the weighing bridge of the electronic belt scale on the conveyor frame. When the material passes by, the weighing roller detects the weight of the material on the belt conveyor and acts on the load cell to generate an electric current proportional to the belt load. The signal is sent to the terminal processor. At the same time, a speed sensor is installed on the belt device, and the measured speed signal is also sent to the terminal processor. The terminal processor integrates...

Problems solved by technology

[0003] However, since the electronic belt scale is a dynamic material on the belt during the measurement operation, deviations will inevitably occur during the dynamic measurement process. During the operation of the belt conveyor, due to the deviation of the belt, mechanical failure, and unevenness of the material on the belt Various reasons may cause the error of the electronic scale (this point is also described in more detail in the later embodiment part), and if the cause of the instantaneous error cannot be discharged in time, the instantaneous error will always exist in the In the subsequent measured instantaneous weight flow data, the instantaneous error at each moment is finally superimposed on the accumulated value, resulting in a large difference between the accumulated value obtained by statistics and the total amount of material actually transported

When the staff realizes this error by entering the background database and analyzing and comparing the recorded measurement data, it is likely that the delivery to the customer has been completed, and in order to make up for this error, it will not only increase the follow-up work amount, it is also easy to affect their own integrity

And even if the instantaneous error is discovered in time, the belt needs to be stopped, and the relevant testing equipment should be cleaned and corrected before restarting the conveyor belt, which reduces the transmission efficiency accordingly.
