【摘要】:近几年,随着国内公路网络的健全和国内物流业的飞速增长,集装箱公路运输逐渐发挥着不可替代的作用。为保障港口、码头、机场集装箱装卸和转场、短距离公路物资运输以及军队户外设备转移,具有自装卸功能的集装箱运输车在公路集装箱运输中扮演着不可替代的角色。传统的自装卸集装箱运输车的装卸过程需要多人协调操作来完成,这不仅降低装卸的效率,增加运输成本,而且由于操作人员位置固定,盲区较大,在起吊过程中极易引发不安全事件。本文针对以上提出的问题,采用无线遥控技术,研究设计了一套提高自装卸集装箱运输车自动化水平的电控系统。首先分析自装卸机构的整体结构和控制动作要求,设计了自装卸机构液压系统。其次,根据控制要求,选用西门子S7-200PLC作为自装卸机构控制器,并研究设计控制方案和控制程序,并进行控制仿真,保证控制程序满足控制要求。然后,采用ARM微控制器、NRF905和NRF24L01射频模块设计双通道的无线遥控器,采用433MHZ和2.4GHZ双通道进行无线传输,提高遥控器的可靠性。最后,通过CAN总线将车载遥控接收器与自装卸机构控制器连接,实现两机通信,以此来提高通信的可靠性。采用无线遥控技术,并改善自装卸机构控制方案能够很好的提高自装卸集装箱运输车自动化水平,使起吊控制更加安全、便捷,不仅开发成本低,而且能够极大地提高经济效益,具有很好的市场前景。
[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.
