【摘要】：在某些高危环境下,作业人员无法进入现场作业环境中,需要以无线遥控的方式对现场作业车辆进行操作,同时需要实时回传现场视频,以辅助作业人员了解作业车辆周围的环境情况。本文从实际需求出发,通过对现有遥控技术进行优劣比较,提出了一套基于网络标准协议的可视化无线遥控系统数据收发方案;网络标准协议即广泛应用的TCP/IP协议,本文旨在实现可视化无线遥控系统中的数据收发功能。可视化无线遥控系统包括遥控端和车载端两个部分,两端各是一个嵌入式系统,二者处于同一个无线局域网中,依靠无线局域网进行数据通信。本文在基于ARM架构的微处理器S5PV210上移植嵌入式Linux系统,然后基于嵌入式Linux系统开发满足数据收发功能需求的应用软件。可视化无线遥控系统数据收发功能实现过程如下,本文首先对可视化无线遥控系统数据收发功能进行需求分析,接着对系统所涉及关键技术进行详细研究,并对所涉及关键技术对应的应用方法进行研究。然后完成了可视化无线遥控系统的总体设计,为后续系统软件开发平台的搭建以及软件实现提供一个可参考的框架。再者在完成系统软件开发平台选择的基础之上,对系统软件开发平台的搭建方法进行详细研究,并完成了平台的搭建工作。最后实现基于网络标准协议的可视化无线遥控系统数据收发功能,除此之外,本文还对系统数据收发功能进行测试,对数据传输时延进行分析,并将视频在不同压缩比下的传输效果进行比较。基于嵌入式系统具有良好的扩展性、丰富的接口,可视化无线遥控系统最大程度利用系统资源,使各部分发挥最大性能,在高数据传输压力下具备一定的容错能力和鲁棒性。
[Abstract]:In some high-risk environments, operators can not enter the field working environment, so they need to operate the field vehicle by wireless remote control, and return the live video in real time. To assist the operator to understand the environment around the working vehicle. In this paper, according to the actual demand, by comparing the advantages and disadvantages of the existing remote control technology, a set of visual wireless remote control system data receiving and receiving scheme based on network standard protocol is proposed. The network standard protocol is the widely used TCP/IP protocol. The purpose of this paper is to realize the data receiving and receiving function in the visual wireless remote control system. The visual wireless remote control system includes two parts: the remote control end and the vehicle end, each of which is an embedded system, which is in the same wireless local area network and relies on the wireless local area network for data communication. In this paper, the embedded Linux system is ported to the microprocessor S5PV210 based on ARM architecture, and then the application software to meet the requirements of data transceiver function is developed based on embedded Linux system. The realization process of data transceiver function of visual wireless remote control system is as follows. In this paper, the requirements of data transceiver function of visual wireless remote control system are analyzed, and then the key technologies involved in the system are studied in detail. The application methods of the key technologies involved are also studied. Then the overall design of visual wireless remote control system is completed, which provides a reference framework for the construction of software development platform and software implementation of the follow-up system. Furthermore, on the basis of completing the selection of the system software development platform, the construction method of the system software development platform is studied in detail, and the construction work of the platform is completed. Finally, the data transceiver function of visual wireless remote control system based on network standard protocol is realized. In addition, this paper also tests the data transceiver function of the system, and analyzes the data transmission delay. The transmission effect of video under different compression ratios is compared. Based on the embedded system has good expansibility, rich interface, visual wireless remote control system makes maximum use of system resources, so that each part of the maximum performance, under high data transmission pressure has a certain fault-tolerant ability and robustness.
