Embedded type weighing system based on intelligent fuzzy control

Abstract

The invention discloses an embedded weighing system, which is based on intelligence-fuzzy-control. The invention specifically relates to an artificiality-intelligence-analysis-based and fuzzy-control weighing system used for proportioning and delivery procedure. The invention is designed to solve the problems of realizing PID control of two-dimensional fuzzy processing form, commingling information of a multi-type sensor, detecting combined series-parallel failure and the weighing system of local and / or remote control. The adopted proposal is as following: A weighing display controller is respectively connected with a weight sensor, a speed sensor, a superordination computer, a transducer and a programmable controller. The weight sensor and the speed sensor are separately connected with a proportioning belt weigh meter. The proportioning belt weigh meter is connected with a main conveyer. The main conveyer is connected with a programmable controller, a material feeder and a transducer. The superordination computers form an Ethernet network. The weighing display controller solidifies a plurality of control procedures. The invention is applicable to industries such as metallurgy, carbonization, chemical industry, tobacco, tragacanth, pottery and porcelain and extraction of heavy metal.

Description

technical field [0001] The invention relates to an embedded weighing system based on intelligent fuzzy control, in particular to a weighing system based on artificial intelligence analysis and fuzzy control, which is used for batching and conveying processes. Background technique [0002] At present, the weighing technology in the batching and conveying process is widely used in energy, metallurgy, manufacturing, transportation, chemical industry and other industries, but most of the weighing systems in the batching and conveying process are controlled by conventional PID adjustment mode. The disadvantages are : First, the accuracy is not high, the stability is not high, and the weighing intelligence is relatively backward, and network management cannot be carried out; second, the quantitative packaging scales, batching scales, and automatic weight inspection scales in the entire weighing system And the real-time dynamic adjustment ability is poor, and it cannot adapt to the...

[0002] At present, the weighing technology in the batching and conveying process is widely used in energy, metallurgy, manufacturing, transportation, chemical industry and other industries, but most of the weighing systems in the batching and conveying process are controlled by conventional PID adjustment mode. The disadvantages are : First, the accuracy is not high, the stability is not high, and the weighing intelligence is relatively backward, and network management cannot be carried out; second, the quantitative packaging scales, batching scales, and automatic weight inspection scales in the entire weighing system And the real-time dynamic adjustment ability is poor, and it cannot adapt to the modern comprehensive batching and conveying system. Third, the traditional weighing system cannot realize local and / or remote virtualization control, and the system does not contain fault diagnosis programs, although individual fault diagnosis procedure, but its diagnosis method is the same as that of traditional electromechanical equipment diagnosis method
