【摘要】：近幾年,隨著國內(nèi)公路網(wǎng)絡(luò)的健全和國內(nèi)物流業(yè)的飛速增長,集裝箱公路運(yùn)輸逐漸發(fā)揮著不可替代的作用。為保障港口、碼頭、機(jī)場集裝箱裝卸和轉(zhuǎn)場、短距離公路物資運(yùn)輸以及軍隊(duì)?wèi)敉庠O(shè)備轉(zhuǎn)移,具有自裝卸功能的集裝箱運(yùn)輸車在公路集裝箱運(yùn)輸中扮演著不可替代的角色。傳統(tǒng)的自裝卸集裝箱運(yùn)輸車的裝卸過程需要多人協(xié)調(diào)操作來完成,這不僅降低裝卸的效率,增加運(yùn)輸成本,而且由于操作人員位置固定,盲區(qū)較大,在起吊過程中極易引發(fā)不安全事件。本文針對(duì)以上提出的問題,采用無線遙控技術(shù),研究設(shè)計(jì)了一套提高自裝卸集裝箱運(yùn)輸車自動(dòng)化水平的電控系統(tǒng)。首先分析自裝卸機(jī)構(gòu)的整體結(jié)構(gòu)和控制動(dòng)作要求,設(shè)計(jì)了自裝卸機(jī)構(gòu)液壓系統(tǒng)。其次,根據(jù)控制要求,選用西門子S7-200PLC作為自裝卸機(jī)構(gòu)控制器,并研究設(shè)計(jì)控制方案和控制程序,并進(jìn)行控制仿真,保證控制程序滿足控制要求。然后,采用ARM微控制器、NRF905和NRF24L01射頻模塊設(shè)計(jì)雙通道的無線遙控器,采用433MHZ和2.4GHZ雙通道進(jìn)行無線傳輸,提高遙控器的可靠性。最后,通過CAN總線將車載遙控接收器與自裝卸機(jī)構(gòu)控制器連接,實(shí)現(xiàn)兩機(jī)通信,以此來提高通信的可靠性。采用無線遙控技術(shù),并改善自裝卸機(jī)構(gòu)控制方案能夠很好的提高自裝卸集裝箱運(yùn)輸車自動(dòng)化水平,使起吊控制更加安全、便捷,不僅開發(fā)成本低,而且能夠極大地提高經(jīng)濟(jì)效益,具有很好的市場前景。
[Abstract]:In recent years, with the improvement of domestic road network and the rapid growth of domestic logistics industry, container road transport gradually plays an irreplaceable role. Transport of goods and materials by short distance road and transfer of military outdoor equipment. The container transport vehicle with self-loading and unloading function plays an irreplaceable role in the road container transportation. The traditional loading and unloading process of the self-loading and unloading container transport vehicle needs the coordination operation of many people to complete. This not only reduces the efficiency of loading and unloading, increases the transportation cost, but also because of the fixed position of the operator, the blind area is large, it is easy to lead to unsafe events in the process of lifting. Using wireless remote control technology, a set of electronic control system is designed to improve the automation level of self-loading and unloading container transport vehicle. Firstly, the overall structure and control operation requirements of self-loading and unloading mechanism are analyzed. The hydraulic system of self-loading and unloading mechanism is designed. Secondly, according to the control requirements, Siemens S7-200 PLC is selected as the self-loading and unloading mechanism controller, and the control scheme and control program are studied. The control simulation is carried out to ensure that the control program meets the control requirements. Then the ARM microcontroller NRF905 and the NRF24L01 radio frequency module are used to design the dual-channel wireless remote controller. The dual channels of 433MHz and 2.4GHz are used for wireless transmission to improve the reliability of the remote controller. Finally, the remote control receiver is connected with the self-loading and unloading mechanism controller by CAN bus. Using wireless remote control technology and improving the control scheme of self-loading and unloading mechanism can improve the automation level of self-loading and unloading container truck. The lifting control is more safe and convenient, not only the development cost is low, but also the economic benefit can be greatly improved, so it has a good market prospect.
