【摘要】：頂堆側(cè)取堆取料機(jī)是一種新興成套散料處理設(shè)備,它既可以通過(guò)刮板系統(tǒng)在儲(chǔ)料場(chǎng)進(jìn)行取料,將物料取到系統(tǒng),又可以通過(guò)臂架帶式輸送機(jī)將系統(tǒng)來(lái)料堆存到料場(chǎng)。因其具有生產(chǎn)效率高、環(huán)保性好、倉(cāng)儲(chǔ)量大等特點(diǎn),已廣泛應(yīng)用于冶金、電力、礦山、建材、大型露天礦、儲(chǔ)料場(chǎng)、倉(cāng)庫(kù)、發(fā)電廠、港口碼頭和煤氣廠等領(lǐng)域。堆取料機(jī)安全、有效的運(yùn)行對(duì)于設(shè)備用戶(hù)常、持續(xù)的生產(chǎn)起著關(guān)鍵性作用。只有正確深入掌握頂側(cè)取堆取料機(jī)的工藝流程和控制方式,才能對(duì)提高自動(dòng)控制水平、充分利用有限的人力資源十分必要,因此研究頂堆側(cè)取堆取料機(jī)控制系統(tǒng)有著十分重要的意義。本文通過(guò)分析頂堆側(cè)取堆取料機(jī)控制系統(tǒng)的結(jié)構(gòu),進(jìn)行PLC系統(tǒng)的硬件配置和軟件組態(tài),設(shè)計(jì)了一套以CANopen現(xiàn)場(chǎng)總線(xiàn)為基本框架的高效控制系統(tǒng)。 通過(guò)分析頂堆側(cè)取堆取料機(jī)的工作工藝流程,開(kāi)發(fā)了一種以CANopen現(xiàn)場(chǎng)總線(xiàn)為基礎(chǔ)的頂堆側(cè)取堆取料機(jī)的控制系統(tǒng),系統(tǒng)采用PLC作為控制器,PLC控制系統(tǒng)具有計(jì)算機(jī)的功能靈活性,完善性和通用性強(qiáng),其有繼電器控制系統(tǒng)的操作方便、價(jià)格便宜、簡(jiǎn)單易懂等優(yōu)點(diǎn)�，F(xiàn)場(chǎng)總線(xiàn)作為連接現(xiàn)場(chǎng)設(shè)備與自動(dòng)化系統(tǒng)的通信網(wǎng)絡(luò),通過(guò)高度智能的現(xiàn)場(chǎng)設(shè)備水分散完成控制器的功能,弱化甚至可以省去了集中控制器的層次,減少設(shè)備和布線(xiàn)費(fèi)用,使控制的風(fēng)險(xiǎn)徹底分散,加上變頻調(diào)速系統(tǒng),可靠的通訊設(shè)施,精密的檢測(cè)手段,提高系統(tǒng)控制的可靠性和自治性。采取一系列抗干擾措施和輔以完善的工業(yè)電視監(jiān)控系統(tǒng),經(jīng)過(guò)試驗(yàn)檢測(cè)和現(xiàn)場(chǎng)調(diào)試,證明該控制系統(tǒng)的可行性。此控制系統(tǒng)可靠性高,通信速率快,抗干擾能力強(qiáng),降低了勞動(dòng)工作強(qiáng)度,提高了設(shè)備的生產(chǎn)效率。 頂側(cè)取堆取料機(jī)控制系統(tǒng)已通過(guò)了現(xiàn)場(chǎng)的實(shí)際測(cè)試和運(yùn)行,滿(mǎn)足頂側(cè)取堆取料機(jī)運(yùn)行工藝要求,得到了用戶(hù)的好評(píng)和認(rèn)可。
[Abstract]:The top pile side heaping machine is a new complete set of bulk processing equipment. It can be used to collect material in the storage yard through scraper system, and to take the material to the system. Because of its high production efficiency, good environmental protection and large storage capacity, it has been widely used in metallurgy, electric power, mines, building materials, large open pit mines, storage yards, warehouses, etc. Power plant, port wharf, gas plant and other fields. Stacker is safe and effective operation plays a key role in equipment users' constant and continuous production. Only by correctly and deeply mastering the technological process and control mode of top-side heap-taker, It is necessary to improve the level of automatic control and make full use of limited human resources. Therefore, it is very important to study the control system of top-side heap-fetching machine. The hardware configuration and software configuration of PLC system are carried out, and an efficient control system based on CANopen fieldbus is designed. Based on the analysis of the working process of the top heap-side stacker, a control system based on CANopen fieldbus is developed. The system adopts PLC as the controller and the PLC control system has the function flexibility of the computer. It has the advantages of convenient operation, cheap price, easy to understand and so on. The fieldbus is used as the communication network connecting the field equipment and the automation system. The function of the controller is accomplished by highly intelligent field equipment with water dispersion, which weakens or even saves the level of the centralized controller, reduces the equipment and wiring costs, distributes the risk of control thoroughly, and adds the frequency conversion speed control system. Reliable communication facilities, precise means of detection, improving the reliability and autonomy of system control. A series of anti-interference measures and a perfect industrial television monitoring system are adopted, which are tested and tested and debugged on the spot. The feasibility of the control system is proved. This control system has the advantages of high reliability, fast communication rate, strong anti-interference ability, reduced labor intensity and improved production efficiency of the equipment. The control system of top side heap-fetching machine has passed the actual test and operation on the spot, which meets the requirements of the operation technology of top-side heap-fetching machine, and has been praised and approved by the users.
