Automatic counterweight loading control device for electronic steelyard detector

Abstract

The invention discloses an automatic counterweight loading control device for an electronic steelyard detector. The control device comprises a host computer module, a digital signal processing module,a fuzzy sliding mode variable structure operation module, a shoe plate elevation driving module and a displacement sensor; the host computer module is used to obtain the loading weight of a target counterweight; according to a counterweight loading instruction m(k) input by the host computer, the digital signal processing module outputs a position instruction r(k) of the displacement sensor in next time; the displacement sensor detects and outputs a position signal x(k) of a shoe plate at present, a control signal output by the fuzzy sliding mode variable structure operation module is obtained via operation of the module, and a shoe plate elevation controller is driven. Thus, the counterweight can be loaded automatically and accurately in high efficiency.

Description

technical field [0001] The invention relates to measurement detection, in particular to an automatic weight loading control device used in an electronic crane scale detection device. Background technique [0002] With the rapid development of my country's economy, the huge demand of logistics and mining industry, the use of weighing equipment in various industries is becoming more and more frequent, the weighing weight is getting larger and larger, and the accuracy requirements are constantly improving. Therefore, accurate and efficient detection devices are more important and more urgent. . [0003] Weighing instruments are developing in the direction of large-scale, and conventional verification methods can no longer meet the requirements of regulations and specifications. Among them, large-tonnage electronic crane scales are more difficult to detect due to the particularity of their loading methods. At present, domestic electronic crane scales are mainly tested with stand...

Problems solved by technology

[0006] In order to avoid the shortcomings of the above-mentioned prior art, the present invention solves the problem that it is difficult to load the detection weight of the large-tonnage electronic crane scale, and provides an automatic weight loading control device for the detection device of the electronic crane scale. By controlling the lifting position of the weight support frame, the effect of controlling the weight loading of the electronic crane scale is achieved. At the same time, the sliding mode control and fuzzy control are combined to improve system stability, reliability and dynamic quality.
