【摘要】：礦井機(jī)車軌道運(yùn)輸是井下矸石、物料等主要的運(yùn)輸方式。井下軌道分布廣泛且交錯(cuò)復(fù)雜,極易發(fā)生運(yùn)輸機(jī)車撞車、追尾等事故,一旦發(fā)生事故會(huì)在短時(shí)間內(nèi)影響整個(gè)礦井的運(yùn)輸生產(chǎn)任務(wù)。隨著采掘運(yùn)輸任務(wù)的不斷增加,煤礦對(duì)運(yùn)輸機(jī)車的實(shí)時(shí)監(jiān)控和調(diào)度也提出了更高的要求,因此研究礦井軌道運(yùn)輸智能監(jiān)控與優(yōu)化調(diào)度系統(tǒng)對(duì)于提高礦井機(jī)車運(yùn)輸效率和礦井經(jīng)濟(jì)效益,保障機(jī)車運(yùn)輸安全具有重要的意義。本文以大屯煤電公司孔莊煤礦為背景,針對(duì)該礦井軌道運(yùn)輸監(jiān)控系統(tǒng)存在的不足,利用PLC控制技術(shù),計(jì)算機(jī)遠(yuǎn)程監(jiān)控技術(shù),網(wǎng)絡(luò)信息技術(shù),傳感器檢測(cè)技術(shù)并結(jié)合蟻群算法機(jī)車優(yōu)化調(diào)度策略實(shí)現(xiàn)了礦井軌道運(yùn)輸?shù)闹悄鼙O(jiān)控與優(yōu)化調(diào)度。首先研究設(shè)計(jì)了軌道運(yùn)輸智能監(jiān)控與優(yōu)化調(diào)度系統(tǒng)的總體結(jié)構(gòu),分析了軌道機(jī)車運(yùn)輸過(guò)程中進(jìn)路區(qū)間信號(hào)機(jī)的設(shè)計(jì)方法以及聯(lián)鎖規(guī)則,論述了系統(tǒng)的控制原理與機(jī)車定位原理。緊接著針對(duì)礦井機(jī)車的運(yùn)輸調(diào)度問(wèn)題,確立了滿足機(jī)車載重量情況下運(yùn)輸路徑最短的優(yōu)化目標(biāo),根據(jù)優(yōu)化目標(biāo)建立了機(jī)車優(yōu)化調(diào)度數(shù)學(xué)模型,并利用蟻群算法對(duì)模型進(jìn)行了求解,完成了機(jī)車運(yùn)行路徑的規(guī)劃。隨后根據(jù)系統(tǒng)功能的實(shí)現(xiàn)和現(xiàn)場(chǎng)設(shè)備情況,完成了控制系統(tǒng)硬件和現(xiàn)場(chǎng)設(shè)備的選型設(shè)計(jì),并對(duì)相關(guān)電氣控制原理圖進(jìn)行設(shè)計(jì),采用西門(mén)子S7-1200 PLC完成系統(tǒng)數(shù)據(jù)的監(jiān)測(cè)和自動(dòng)控制運(yùn)行。在系統(tǒng)網(wǎng)絡(luò)方面,利用PROFIBUS DP現(xiàn)場(chǎng)總線和PROFINET工業(yè)以太網(wǎng)以及無(wú)線通訊構(gòu)建系統(tǒng)通訊網(wǎng)絡(luò),實(shí)現(xiàn)系統(tǒng)的數(shù)據(jù)傳輸。最后利用STEP7 V13編寫(xiě)PLC控制系統(tǒng)程序,實(shí)現(xiàn)機(jī)車調(diào)度運(yùn)行過(guò)程中進(jìn)路區(qū)間轉(zhuǎn)轍機(jī)信號(hào)機(jī)的自動(dòng)控制和信號(hào)閉鎖;采用WINCC設(shè)計(jì)監(jiān)控計(jì)算機(jī)顯示界面,實(shí)現(xiàn)機(jī)車運(yùn)行狀態(tài)的實(shí)時(shí)監(jiān)測(cè)和遠(yuǎn)程控制。
[Abstract]:Mine locomotive rail transportation is the main transportation mode of underground gangue and materials. The underground track is widely distributed and interlaced and complex, so it is easy to happen accidents such as vehicle collision and rear-end. Once the accident occurs, it will affect the whole mine transportation and production task in a short period of time. With the increasing of mining and transportation tasks, coal mines have put forward higher requirements for real-time monitoring and dispatching of transport vehicles. Therefore, it is of great significance to study the intelligent monitoring and optimal dispatching system for mine rail transportation to improve the efficiency of mine locomotive transportation and mine economic benefit, and to ensure the safety of locomotive transportation. This paper takes Kongzhuang Coal Mine of Datun Coal Power Company as the background, aiming at the shortcomings of the monitoring system of railway transportation in this mine, using PLC control technology, computer remote monitoring technology, network information technology, etc. Sensor detection technology and ant colony algorithm combined with locomotive optimal scheduling strategy to achieve intelligent monitoring and optimal scheduling of mine rail transportation. Firstly, the overall structure of the intelligent monitoring and optimal dispatching system for rail transportation is studied, the design method and interlocking rules of the route interval signal machine in the course of railway locomotive transportation are analyzed, and the control principle and locomotive positioning principle of the system are discussed. Then aiming at the transportation scheduling problem of mine locomotives, the optimization goal of the shortest transportation path is established to meet the load load of locomotives, and the mathematical model of locomotive optimal dispatching is established according to the optimization objectives. Ant colony algorithm is used to solve the model, and the locomotive running path planning is completed. Then, according to the realization of the system function and the situation of the field equipment, the selection design of the control system hardware and field equipment is completed, and the related electrical control schematic diagram is designed. Siemens S7-1200 PLC is used to monitor and control the system data. In the aspect of system network, the system communication network is constructed by using PROFIBUS DP fieldbus, PROFINET industrial Ethernet and wireless communication to realize the data transmission of the system. Finally, the program of PLC control system is programmed by STEP7 V13 to realize the automatic control and signal locking of the signal of the route interval switch machine in the course of locomotive dispatching, and the display interface of the monitor computer is designed by using WINCC. Realize the real-time monitoring and remote control of locomotive running state.
