【摘要】：現(xiàn)代采礦中安全事故頻發(fā),井下人員的人身安全受到了嚴(yán)重的威脅。尤其是在操作鏟運(yùn)車進(jìn)行礦石開(kāi)采的過(guò)程中,經(jīng)常出現(xiàn)塌方導(dǎo)致人員和車輛被埋。正是由于井下開(kāi)采存在這樣的危險(xiǎn)性,國(guó)內(nèi)外的礦業(yè)公司都在盡量避免和減少人員直接操作礦運(yùn)車作業(yè)。加之近年來(lái),隨著科技的發(fā)展和技術(shù)的創(chuàng)新,數(shù)字化礦山技術(shù)已經(jīng)成為采礦業(yè)的主要發(fā)展趨勢(shì),因此無(wú)線遙控鏟運(yùn)車應(yīng)運(yùn)而生。本課題主要是設(shè)計(jì)一種基于Wi-Fi傳輸?shù)目梢暬ㄓ每纱钶d無(wú)線遙控模塊。借以實(shí)現(xiàn)在100米的可視范圍內(nèi)對(duì)工程車輛的無(wú)線遙控功能,同時(shí)兼顧實(shí)時(shí)視頻回傳,保證車輛操作人員在遙控鏟運(yùn)車的同時(shí)能夠通過(guò)車載攝像頭和回傳裝置及時(shí)獲取車輛運(yùn)行狀態(tài)與信息,從而避免直接駕駛鏟運(yùn)車而導(dǎo)致的潛在危險(xiǎn)。而本文的主要工作則是設(shè)計(jì)無(wú)線遙控系統(tǒng)的軟硬件,并在此基礎(chǔ)上設(shè)計(jì)開(kāi)發(fā)不同種類的可搭載模塊,以實(shí)現(xiàn)在不同車輛和場(chǎng)合中的通用性搭載。首先,本文結(jié)合井下工作環(huán)境以及系統(tǒng)功能與性能指標(biāo)的需求,同時(shí)兼顧遙控信號(hào)與視頻信號(hào)的傳輸,對(duì)比了Wi-Fi、RFID、ZigBee等無(wú)線傳輸方式,分別從經(jīng)濟(jì)性、通用性、應(yīng)用前景以及是否符合需求等方面進(jìn)行了對(duì)比,選取了Wi-Fi作為無(wú)線通信方式。其次,在設(shè)計(jì)硬件電路時(shí)不僅僅考慮井下鏟運(yùn)車這單一車輛的遙控需求,而是在提供核心遙控模塊的基礎(chǔ)上進(jìn)行通用性分析,根據(jù)所應(yīng)用的不同場(chǎng)合規(guī)劃出實(shí)現(xiàn)特殊功能的硬件模塊,使操作人員可以根據(jù)需求自行選擇搭配,即可定制、可擴(kuò)展性。最后,在Ubuntu開(kāi)發(fā)環(huán)境中將系統(tǒng)移植到整個(gè)硬件系統(tǒng)平臺(tái),實(shí)現(xiàn)功能集成,并進(jìn)行無(wú)線遙控?cái)?shù)據(jù)和視頻回傳數(shù)據(jù)的整合分析,以滿足穩(wěn)定傳輸和控制的功能。在設(shè)計(jì)整體結(jié)構(gòu)時(shí),考慮到如何使電路盡量的簡(jiǎn)潔化、輕量化,以保證最后封裝的整體系統(tǒng)可以讓操作人員隨身攜帶,而且長(zhǎng)時(shí)間佩戴不會(huì)導(dǎo)致過(guò)度疲勞。并在此基礎(chǔ)上規(guī)劃模塊,設(shè)計(jì)遙控器的整體機(jī)械結(jié)構(gòu)與外觀,通過(guò)3D打印技術(shù)加工出殼體。
[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.
