【摘要】：伴隨著工業(yè)的高速發(fā)展,生產(chǎn)規(guī)模的不斷擴(kuò)大,大型流水生產(chǎn)線已成為主流的生產(chǎn)模式。隨著生產(chǎn)效率的提升,企業(yè)對(duì)產(chǎn)品質(zhì)量日趨關(guān)注,檢重秤被越來(lái)越多的產(chǎn)品制造商所采用。目前國(guó)內(nèi)企業(yè)對(duì)檢重行業(yè)也愈加關(guān)注,但其研發(fā)的產(chǎn)品檢重精度和檢重速度并不是太高,而且需要占用人力對(duì)設(shè)備的運(yùn)行狀態(tài)進(jìn)行監(jiān)測(cè),造成大量的人力資源浪費(fèi),增加了生產(chǎn)成本。針對(duì)現(xiàn)在國(guó)內(nèi)檢重行業(yè)存在的問(wèn)題,設(shè)計(jì)研發(fā)一款基于無(wú)線通信技術(shù)的檢重秤及監(jiān)測(cè)系統(tǒng)。該系統(tǒng)集檢重測(cè)量與監(jiān)測(cè)于一體,檢重裝置主要利用稱重傳感器將待檢物體的重量信息轉(zhuǎn)換為電信號(hào),通過(guò)A/D轉(zhuǎn)換模塊對(duì)信號(hào)進(jìn)行放大并轉(zhuǎn)換為數(shù)字信號(hào)傳遞至微處理器。為了提高檢重的精度,微處理器采用卡爾曼濾波算法和最小二乘支持向量機(jī)實(shí)現(xiàn)對(duì)干擾的濾除和檢重終值的預(yù)測(cè)。為了實(shí)現(xiàn)對(duì)檢重裝置相關(guān)運(yùn)行參數(shù)的檢測(cè),系統(tǒng)采用Wi-Fi無(wú)線通信模塊實(shí)現(xiàn)檢重裝置的網(wǎng)絡(luò)連接,同時(shí)設(shè)計(jì)一款以Android智能手機(jī)為載體的移動(dòng)監(jiān)測(cè)應(yīng)用。通過(guò)組建以AP為基礎(chǔ)核心的覆蓋工廠的無(wú)線局域網(wǎng)絡(luò),實(shí)現(xiàn)檢重裝置與移動(dòng)監(jiān)測(cè)端之間的數(shù)據(jù)傳輸。移動(dòng)監(jiān)測(cè)端需要對(duì)檢重裝置的檢重?cái)?shù)據(jù)、運(yùn)行狀態(tài)及相關(guān)參數(shù)等信息進(jìn)行監(jiān)測(cè),這就需要在二者之間進(jìn)行大量的數(shù)據(jù)傳輸。為了充分發(fā)揮系統(tǒng)的性能,提高系統(tǒng)的處理能力,設(shè)計(jì)選用C/S體系結(jié)構(gòu)作為監(jiān)測(cè)系統(tǒng)的軟件系統(tǒng)體系結(jié)構(gòu)模式。基于無(wú)線通信技術(shù)的檢重秤及監(jiān)測(cè)系統(tǒng)實(shí)現(xiàn)了對(duì)物件重量的精準(zhǔn)測(cè)量和對(duì)檢重裝置運(yùn)行信息的監(jiān)測(cè)。與以往的設(shè)備相對(duì)比,它提高了檢重的精度和檢重速度。同時(shí)通過(guò)移動(dòng)監(jiān)測(cè)端實(shí)現(xiàn)對(duì)檢重裝置的遠(yuǎn)程監(jiān)測(cè),減少了人力資源的投入,降低生產(chǎn)成本,實(shí)現(xiàn)了工業(yè)生產(chǎn)過(guò)程的智能化管理。
[Abstract]:With the rapid development of industry and the expansion of production scale, large production line has become the mainstream production mode. With the improvement of production efficiency, enterprises pay more and more attention to product quality. At present, domestic enterprises are paying more and more attention to the heavy inspection industry, but the precision and speed of the products developed by them are not too high, and they need to use manpower to monitor the running state of the equipment, resulting in a large amount of human resources waste. Increased production costs. Aiming at the problems existing in domestic weighing industry, this paper designs and develops a scale and monitoring system based on wireless communication technology. In this system, the weight information of the object to be detected is converted into electrical signal by using the weighing sensor, and the signal is amplified and converted to digital signal through the Ar / D conversion module. In order to improve the accuracy of detection, the Kalman filter algorithm and least square support vector machine are used to filter the interference and predict the final value. In order to detect the operation parameters of the weighing device, the Wi-Fi wireless communication module is used to realize the network connection of the device, and a mobile monitoring application based on Android smart phone is designed. A wireless local area network based on AP is set up to realize the data transmission between the weight-checking device and the mobile monitoring terminal. The mobile monitoring terminal needs to monitor the information of the weighing data, the running state and the related parameters of the device, which requires a large amount of data transmission between the two. In order to give full play to the performance of the system and improve the processing ability of the system, the C / S architecture is selected as the software system architecture model of the monitoring system. Based on the wireless communication technology, the weigher and its monitoring system can accurately measure the weight of the object and monitor the operation information of the device. Compared with the previous equipment, it improves the accuracy and speed of weight check. At the same time, the remote monitoring of the weight check device is realized through the mobile monitoring terminal, which reduces the input of human resources, reduces the production cost, and realizes the intelligent management of the industrial production process.
