【摘要】：作為煤礦生產(chǎn)四大系統(tǒng)之一,排水系統(tǒng)承擔著保障礦井安全生產(chǎn)的重要任務(wù),起到排除積水的作用。目前,傳統(tǒng)排水系統(tǒng)普遍控制類型為繼電器控制,針對水泵的操作,均由人工完成。隨著科技不斷發(fā)展,傳統(tǒng)排水系統(tǒng)已經(jīng)開始慢慢與微電子應(yīng)用技術(shù)以及先進控制理論相結(jié)合,在提高工業(yè)設(shè)備安全性和經(jīng)濟性上有著非常重要的作用。井下排水監(jiān)控系統(tǒng)作為傳統(tǒng)排水系統(tǒng)的升級產(chǎn)品,利用現(xiàn)代工業(yè)控制技術(shù)和檢測技術(shù)來完善自身功能,從而實現(xiàn)排水系統(tǒng)的自動化,達到水泵房無人化運作的目的。首先基于動態(tài)規(guī)劃法來提出優(yōu)化策略,然后重點闡述水位模糊PID算法的應(yīng)用,最后建立基于ZigBee無線技術(shù)的網(wǎng)絡(luò)架構(gòu)設(shè)計,從而實現(xiàn)井下排水監(jiān)控系統(tǒng)的控制策略優(yōu)化、實現(xiàn)遠程監(jiān)控。本文將重點從如下三方面來進行闡述:(1)控制策略的優(yōu)化設(shè)計�？刂撇呗缘膬�(yōu)化設(shè)計所需遵守的原則為避峰填谷原則,根據(jù)此原則完成系統(tǒng)離散數(shù)學模型的構(gòu)建工作。然后借助最優(yōu)化原理和動態(tài)規(guī)劃法來完成分段決策控制,采用Dijkstra算法完成系統(tǒng)離散數(shù)學模型的最優(yōu)控制策略選擇。所得到的最優(yōu)控制策略可以按照實際涌水量及用電量來合理調(diào)度系統(tǒng)的運作。(2)水位模糊PID算法設(shè)計及實現(xiàn)。水位模糊PID算法設(shè)計需要參照排水系統(tǒng)的實際情況來完成,并且采用Matlab/Simulink軟件來完成仿真,從而得到模糊PID的響應(yīng)性特征、抗干擾性特征以及適應(yīng)性特征。最后結(jié)合OPC技術(shù)來實現(xiàn)上位機及可編程控制器的實時通信。(3)基于ZigBee無線技術(shù)的網(wǎng)絡(luò)架構(gòu)設(shè)計。根據(jù)礦井的環(huán)境特征來選擇ZigBee技術(shù)作為無線通信技術(shù),并且配置可編程控制器及組態(tài)軟件WINCC作為監(jiān)控中心來實現(xiàn)對排水系統(tǒng)的現(xiàn)場控制及遠程監(jiān)控。
[Abstract]:As one of the four systems in coal mine production, drainage system undertakes the important task of ensuring mine safety production, and plays the role of removing stagnant water. At present, relay control is the general control type of traditional drainage system. With the development of science and technology, the traditional drainage system has begun to combine with microelectronic application technology and advanced control theory. The underground drainage monitoring system, as an upgrade product of traditional drainage system, makes use of modern industrial control technology and detection technology to improve its own function. In order to realize the automation of drainage system and achieve the purpose of water pump house operation without human being, the optimization strategy is put forward based on dynamic programming method, and then the application of fuzzy PID algorithm of water level is expounded emphatically. Finally, the design of network architecture based on ZigBee wireless technology is established to optimize the control strategy of underground drainage monitoring system. This paper will focus on the following three aspects: 1) the optimal design of control strategy. The principle of optimal design of control strategy is the principle of peak avoidance and valley filling. According to this principle, the discrete mathematical model of the system is constructed, and then the piecewise decision control is completed by the optimization principle and the dynamic programming method. The Dijkstra algorithm is used to select the optimal control strategy for the discrete mathematical model of the system, and the optimal control strategy can be obtained according to the actual water inflow and electricity consumption to reasonably dispatch the operation of the system. Water level fuzzy PID algorithm design and implementation. Water level fuzzy PID algorithm design needs to refer to the actual situation of the drainage system to complete. And the Matlab/Simulink software is used to complete the simulation, thus the response characteristics of fuzzy PID are obtained. The features of anti-jamming and adaptability. Finally, the real-time communication between PC and PLC is realized with OPC technology. The design of network architecture based on ZigBee wireless technology. According to the characteristics of mine environment, ZigBee technology is selected as wireless communication technology. And the programmable controller and the configuration software WINCC are used as the monitoring center to realize the field control and remote monitoring of the drainage system.
