【摘要】：现代采矿中安全事故频发,井下人员的人身安全受到了严重的威胁。尤其是在操作铲运车进行矿石开采的过程中,经常出现塌方导致人员和车辆被埋。正是由于井下开采存在这样的危险性,国内外的矿业公司都在尽量避免和减少人员直接操作矿运车作业。加之近年来,随着科技的发展和技术的创新,数字化矿山技术已经成为采矿业的主要发展趋势,因此无线遥控铲运车应运而生。本课题主要是设计一种基于Wi-Fi传输的可视化通用可搭载无线遥控模块。借以实现在100米的可视范围内对工程车辆的无线遥控功能,同时兼顾实时视频回传,保证车辆操作人员在遥控铲运车的同时能够通过车载摄像头和回传装置及时获取车辆运行状态与信息,从而避免直接驾驶铲运车而导致的潜在危险。而本文的主要工作则是设计无线遥控系统的软硬件,并在此基础上设计开发不同种类的可搭载模块,以实现在不同车辆和场合中的通用性搭载。首先,本文结合井下工作环境以及系统功能与性能指标的需求,同时兼顾遥控信号与视频信号的传输,对比了Wi-Fi、RFID、ZigBee等无线传输方式,分别从经济性、通用性、应用前景以及是否符合需求等方面进行了对比,选取了Wi-Fi作为无线通信方式。其次,在设计硬件电路时不仅仅考虑井下铲运车这单一车辆的遥控需求,而是在提供核心遥控模块的基础上进行通用性分析,根据所应用的不同场合规划出实现特殊功能的硬件模块,使操作人员可以根据需求自行选择搭配,即可定制、可扩展性。最后,在Ubuntu开发环境中将系统移植到整个硬件系统平台,实现功能集成,并进行无线遥控数据和视频回传数据的整合分析,以满足稳定传输和控制的功能。在设计整体结构时,考虑到如何使电路尽量的简洁化、轻量化,以保证最后封装的整体系统可以让操作人员随身携带,而且长时间佩戴不会导致过度疲劳。并在此基础上规划模块,设计遥控器的整体机械结构与外观,通过3D打印技术加工出壳体。
[Abstract]:Safety accidents frequently occur in modern mining, and the personal safety of underground personnel is seriously threatened. Especially in the process of ore mining with shovel trucks, landslides often occur, resulting in buried personnel and vehicles. Because there is such a danger in underground mining, mining companies at home and abroad are trying to avoid and reduce the number of direct operation of mine transport vehicles. In addition, in recent years, with the development of science and technology and technological innovation, digital mine technology has become the main development trend of mining industry, so wireless remote control shovel truck came into being. This subject is to design a visual universal wireless remote control module based on Wi-Fi transmission. In order to realize the wireless remote control function of the construction vehicle in the visual range of 100 meters, and at the same time to take into account the real-time video return, At the same time, the vehicle operator can obtain the running status and information of the vehicle through the on-board camera and return device in time, so as to avoid the potential danger caused by driving the shovel truck directly. The main work of this paper is to design the hardware and software of the wireless remote control system, and on this basis to design and develop different kinds of loadable modules to realize the universal loading in different vehicles and occasions. First of all, combining with the requirement of underground working environment and system function and performance index, taking into account the transmission of remote control signal and video signal, this paper compares wireless transmission methods such as Wi-Fi RF ID and ZigBee, respectively from economy, generality, etc. The application prospect and whether meet the requirements are compared, and Wi-Fi is chosen as the wireless communication mode. Secondly, the hardware circuit is designed not only to consider the remote control requirement of the single vehicle, but also to analyze the generality on the basis of providing the core remote control module. According to the different situation of the application, the hardware module can be designed to realize the special function, so that the operator can choose the matching according to the demand, which can be customized and extensible. Finally, the system is transplanted to the whole hardware system platform in Ubuntu development environment to realize the function integration, and the integration analysis of wireless remote control data and video return data is carried out to satisfy the function of stable transmission and control. When designing the whole structure, we should consider how to make the circuit as simple and lightweight as possible, so as to ensure that the final package of the whole system can be carried by the operator, and that wearing it for a long time will not lead to excessive fatigue. On the basis of this, the whole mechanical structure and appearance of remote controller are designed, and the shell is machined by 3D printing technology.
