【摘要】：在信息化時代,電子元件的作用舉足輕重。其中,薄膜電容器憑著良好的高頻特性以及耐壓值高、節(jié)能環(huán)保的優(yōu)點在智能照明、新能源汽車等新型產(chǎn)業(yè)中應(yīng)用廣泛。隨著這些產(chǎn)業(yè)的發(fā)展,薄膜電容的市場需求量越來越大。我國是薄膜電容器生產(chǎn)大國,然而只能占領(lǐng)中低端市場,與國際上的領(lǐng)先水平尚有一定差距。這一差距不僅是因為制造工藝水平較低,更是因為車間信息化技術(shù)的落后造成的。21世紀(jì)以來,“工業(yè)4.0”、“工業(yè)互聯(lián)網(wǎng)”等物聯(lián)網(wǎng)技術(shù)概念陸續(xù)推出,然而我國很多薄膜電容器生產(chǎn)企業(yè)依然采用手寫任務(wù)、人工統(tǒng)計的管理方式,不僅容易產(chǎn)生紕漏,而且管理成本高,生產(chǎn)效率低。本文所研究的薄膜電容器數(shù)字化生產(chǎn)及信息管理系統(tǒng)是一個基于物聯(lián)網(wǎng)與信息技術(shù),融合了工業(yè)化和信息化的生產(chǎn)管理系統(tǒng)。系統(tǒng)由數(shù)據(jù)采集終端、數(shù)據(jù)中繼器、服務(wù)器、數(shù)據(jù)庫和監(jiān)控管理客戶端以及云服務(wù)器組成,實現(xiàn)了對薄膜電容器生產(chǎn)兩個主要工序的生產(chǎn)信息采集。系統(tǒng)的硬件部分主要由數(shù)據(jù)采集終端和數(shù)據(jù)中繼器構(gòu)成。這兩者均以STM32F103單片機作為核心處理器,并且采用了μC/OS-Ⅱ嵌入式操作系統(tǒng)作為軟件開發(fā)平臺。采集終端帶有LCD觸摸屏,負(fù)責(zé)生產(chǎn)數(shù)據(jù)采集和人機交互;中繼器則主要負(fù)責(zé)輪尋終端工作狀態(tài)并通過WiFi向數(shù)據(jù)服務(wù)器傳輸數(shù)據(jù)。數(shù)據(jù)采集終端和數(shù)據(jù)中繼器之間通過CAN總線通信。系統(tǒng)的應(yīng)用層軟件部分由服務(wù)器、管理客戶端和數(shù)據(jù)庫組成。系統(tǒng)的網(wǎng)絡(luò)層采用Socket進行通信。服務(wù)器與客戶端都是基于.NET Framework 4.0的架構(gòu)開發(fā)的。數(shù)據(jù)庫由SQL Server搭建而成。監(jiān)控管理客戶端實現(xiàn)了大屏幕滾動監(jiān)控、生產(chǎn)任務(wù)下發(fā)、報表打印等功能。經(jīng)過實驗室和車間現(xiàn)場的調(diào)試,完成了對系統(tǒng)完整功能的測試。測試結(jié)果表明:本系統(tǒng)全部實現(xiàn)了預(yù)期的功能。系統(tǒng)可以通過監(jiān)控管理客戶端實現(xiàn)對薄膜電容器生產(chǎn)車間的實時數(shù)據(jù)進行采集并監(jiān)控,同時也可以將生產(chǎn)指令信息發(fā)送至每臺生產(chǎn)設(shè)備所連接的數(shù)據(jù)采集終端上。除此以外,本文對數(shù)據(jù)的通信能力在實際工作環(huán)境下進行了測試,驗證了數(shù)據(jù)服務(wù)器的實時數(shù)據(jù)處理能力。本文設(shè)計的薄膜電容器數(shù)字化及信息管理系統(tǒng)對中小型電子生產(chǎn)企業(yè)的信息化管理升級具有良好的借鑒作用。
[Abstract]:In the information age, electronic components play an important role. Among them, thin film capacitors are widely used in intelligent lighting, new energy vehicles and other new industries with good high frequency characteristics, high voltage value, energy saving and environmental protection. With the development of these industries, the market demand for thin film capacitors is increasing. China is a big country in the production of thin film capacitors, but it can only occupy the middle and low end market, which is still far from the international leading level. This gap is caused not only by the low level of manufacturing technology, but also by the backward information technology in the workshop. Since the 21st century, the concepts of "industrial 4.0", "industrial Internet" and other Internet of things technologies have been introduced one after another. However, many film capacitor manufacturing enterprises still use handwritten tasks, manual statistical management, not only easy to make mistakes, but also high management costs, low production efficiency. The digital production and information management system of thin film capacitor is a production management system based on Internet of things and information technology, which combines industrialization and information technology. The system consists of a data acquisition terminal, a data repeater, a server, a database and monitoring management client and a cloud server. The hardware of the system is mainly composed of data acquisition terminal and data repeater. Both of them use STM32F103 microcontroller as the core processor and 渭 C / OS- 鈪，
