【正文】 e electrical machinery of executive body, enable transporting the flow of supplies on belts to stabilize in the adjacent place of settlement value as much as possible, have a good static index and dynamic performance.Automatic batching and weighing system is widely applied in industrial and agricultural production and social life in all areas. Especially the metallurgy, coal, chemicals, cement industries, often need to spread in the dynamic process of belt conveyor, and continuous weigh on conveying the flow adjustment and control, accurate ratio.The quality control of ingredients directly relates to the enterprise can produce smoothly. If the quality of pound reach requirements, causing a waste of energy, raw materials, while influence the quality of the products and productivity, and some of the important position of the ingredients for the production of mistakes even a accident. Therefore, the high precision and ingredients ingredients and how quickly the whole manufacturing restricts the product quality and yield response, so the quality and yield of pounding process control give enough attention. Electronic says automatic batching system can be set according to the input ratio and flow control of material flow, thereby achieve control of product quality and yield of the objective is to realize the automatic production process, and intelligent, enterprise39。同時(shí)，隨著電子計(jì)算機(jī)技術(shù)和自動(dòng)控制技術(shù)的飛速發(fā)展，該系統(tǒng)所應(yīng)用的技術(shù)更加先進(jìn)，領(lǐng)域更加廣泛，可以采取的方案更加靈活多樣，而且，由于系統(tǒng)往往耗資巨大，用戶的實(shí)際條件也各不相同。尤其是冶金、煤炭、化工、水泥等行業(yè)中，常常需要對(duì)散料進(jìn)行皮帶輸送過程中的動(dòng)態(tài)連續(xù)稱量，而且要對(duì)輸送中的流量進(jìn)行調(diào)節(jié)、控制、達(dá)到準(zhǔn)確的配比。1）： 配料電子稱配料電子皮帶稱對(duì)經(jīng)過皮帶的散裝物料進(jìn)行自動(dòng)的連續(xù)稱量和累計(jì)，具有運(yùn)輸和計(jì)量兩種功能。 監(jiān)控軟件的主要功能有：根據(jù)生產(chǎn)配方和產(chǎn)量目標(biāo)對(duì)稱重過程進(jìn)行自動(dòng)控制，對(duì)稱重?cái)?shù)據(jù)進(jìn)行統(tǒng)計(jì)管理并實(shí)現(xiàn)打印。 現(xiàn)場控制模塊主要用于設(shè)置工程參數(shù)，監(jiān)測并控制現(xiàn)場配料活動(dòng)。即生產(chǎn)編號(hào)，完成時(shí)間，分班情況，起始時(shí)刻，班累計(jì)手動(dòng)/自動(dòng)清零，單機(jī)/同時(shí)完工及其他皮帶稱儀表參數(shù)?？刂葡到y(tǒng)的主要組成部分有電子皮帶秤，可編程控制器，通訊系統(tǒng)設(shè)計(jì)和監(jiān)控軟件的功能模塊等等，電子皮帶稱的組成及工作原理下文有具體的說明這里先不進(jìn)行闡述，可編程控制器采用OMROM公司CQM1H型模塊式可編程控制器，配置CQM1HCPU21E型中央處理器模塊，CQM1PA203型電源模塊，4個(gè)CQM1212型16點(diǎn)I/O輸入模塊，2個(gè)CQM1OC222型16點(diǎn)I/O輸出模塊，系統(tǒng)模塊點(diǎn)數(shù)共112點(diǎn)。2）： 儀表控制柜儀表控制柜主要包括七臺(tái)皮帶稱儀表，每臺(tái)皮帶稱儀表接受來自稱重傳感器的重量毫伏信號(hào)和來自測速傳感器的帶速脈沖信號(hào)，計(jì)算出流量和累計(jì)量。如果配制的質(zhì)量達(dá)不到要求，輕則造成原料、能源的浪費(fèi)，重則影響產(chǎn)品的質(zhì)量和生產(chǎn)率，并且有些重要生產(chǎn)崗位的配料失誤甚至?xí)o整個(gè)生產(chǎn)釀成事故。自動(dòng)稱重配料系統(tǒng)的結(jié)構(gòu)組成主要由輸送機(jī)架、稱重傳感器、測速傳感器、秤架、主動(dòng)滾筒、從動(dòng)滾筒、輸送帶、張緊裝置、拖動(dòng)裝置、調(diào)偏裝置等組成。自動(dòng)稱重配料系統(tǒng)可以按照設(shè)定配比和流量控制各輸入物料的瞬時(shí)流量，從而達(dá)到控制各種產(chǎn)品的質(zhì)量和產(chǎn)量的目的，是實(shí)現(xiàn)生產(chǎn)過程自動(dòng)化和智能化、企業(yè)的科學(xué)管理、安全穩(wěn)定生產(chǎn)和節(jié)能降耗的重要技術(shù)手段。s scientific management, safe and stable production and energy consumption is the important technical means. Computer control system in the production of ingredients used not only can improve the yield and quality ingredients and greatly reduce the labor intensity, and post to improve production efficiency. Because the system of production lines, with the same ingredients and posed of daytime belt says system for example. This system mainly consists of ingredients, instrument, electronic control frequency, industrial control puter cabinet, and monitoring and management software.1) ingredients electronic saidIngredients of electronic belt says the bulk materials through belt of automatic weighing and continuous accumulated, transportation and measuring two functions. Weighing part adopts resistance strain working principle, structure, roller leveraged practical work, belt constant velocity measurement called by feeding speed regulat
