隨著傳感器技術(shù)、電子技術(shù)和微機(jī)技術(shù)的崛起,動(dòng)態(tài)稱重技術(shù)得到了迅速發(fā)展。動(dòng)態(tài)稱重系統(tǒng)在數(shù)字化,智能化等方面有長(zhǎng)足的進(jìn)步,稱重系統(tǒng)的研究與開發(fā)也進(jìn)入了一個(gè)嶄新的階段。傳輸帶動(dòng)態(tài)稱重系統(tǒng)是對(duì)傳輸帶上的散狀固體物料或粉料進(jìn)行連續(xù)稱量的系統(tǒng),在電力、化工、煤炭、糧食等行業(yè)都有較廣泛的應(yīng)用,市場(chǎng)需求巨大。但是,我國(guó)自行研制的相關(guān)產(chǎn)品普遍功能單一,精度不高。所以改善現(xiàn)有稱重裝置、開發(fā)研究功能齊全的動(dòng)態(tài)稱重系統(tǒng)是勢(shì)在必行的。本文論述了一套基于單片機(jī)的傳輸帶動(dòng)態(tài)稱重系統(tǒng),很好的解決了上述不足。首先對(duì)傳輸帶動(dòng)態(tài)稱重系統(tǒng)的整體結(jié)構(gòu)、系統(tǒng)模型及其工作原理進(jìn)行詳細(xì)淺析淺析,接著針對(duì)應(yīng)用廣泛的單托輥式秤架的動(dòng)態(tài)計(jì)量誤差進(jìn)行了淺析淺析,對(duì)傳統(tǒng)誤差淺析淺析策略做了改善,從數(shù)學(xué)角度確認(rèn)了皮帶張力的影響,并且采用數(shù)學(xué)建模淺析淺析的策略對(duì)誤差進(jìn)行校正,較好的解決了動(dòng)態(tài)計(jì)量精度低的不足。具體提出了系統(tǒng)硬件和軟件的設(shè)計(jì)策略,給出了數(shù)據(jù)處理算法和其編程的設(shè)計(jì)。系統(tǒng)使用24位精度模/數(shù)轉(zhuǎn)換芯片AD7730轉(zhuǎn)換稱重傳感器信號(hào),保證了數(shù)據(jù)轉(zhuǎn)換的高精度。經(jīng)過實(shí)驗(yàn)證明,該系統(tǒng)能夠有效提高動(dòng)態(tài)稱重系統(tǒng)的計(jì)量精度,誤差在0.2%以內(nèi)。并且系統(tǒng)功能完善,實(shí)現(xiàn)了計(jì)量數(shù)據(jù)的實(shí)時(shí)監(jiān)控顯示和保存打印,系統(tǒng)擴(kuò)展了現(xiàn)場(chǎng)總線接口,很好的滿足了工業(yè)自動(dòng)化和管理現(xiàn)代化的需求。

【Abstract】 With the development of technology of sensor, electronic and computer, the dynamic weighing technology is developing rapidly. Weighing system made significant progress in the digital and intelligent, the research of Weighing system has entered a new phase. Belted dynamic weight equipment is designed for continuous weighing the bulk solids or powders on conveyor belt. And it is widely used in the fields of electricity, chemical, coal and food. However, our related products generally with single function and low precision. Therefore, the improvement of existing weighing devices, research and development functional dynamic weighing system is imperative.This paper presents a belted dyamic weighing system based on SCM, which is a good solution to this problem. In this paper, the overall structure of the weighing system is present first, and detailed analysis of the system model and working principle. It analyzes the cause of dynamic measurement errors, and builds a mathmematical model for dynamic measurement errors of single-idler electronic belt conveyor scale. According to the model, the proposed approach use algorithm to correct errors. Solved the problem of low dynamic measurement accuracy. Then the design of system hardware and software is present. And data processing algorithms and their programming design. System uses 24-bit precision A/D converter AD7730 convert the weighing signal to ensure high-precision measurement results. The result has shown the measurement errors are effectively reduced, and the measurement accuracy can up to 0.2%. The system presented in this paper is characterized by high precision, good stability and achieved the functions of real time monitoring and data preservation. And with the Profibus interface, this system was well positioned to meet the requirements of industrial automation and management modernization.
