| The operators can’t enter the operation site in some high-risk environments,so it’s needed to operate vehicles that in the operation site with wireless remote control;at the same time real-time video should be returned to assist the operators to understand the environment around the operation vehicles better.From the actual demand,through comparing the advantages and disadvantages of the existing remote control technology,a set of data transceiver scheme of visual wireless remote control system based on network standard protocol was proposed.The network standard protocol is widely used TCP/IP protocol,this thesis aims to realize the data transceiver function of visual wireless remote control system.The visual wireless remote control system includes remote control terminal and vehicle terminal,both are in the same wireless local area network.The two terminals rely on wireless local area network for data communication,and either is an embedded system.In this thesis,the embedded Linux system was transplanted based on arm architecture microprocessor S5PV210,and then the application software based on embedded Linux system was developed to meet the data transceiver function of the visual wireless remote control system.The realization process of data transceiver function of visual wireless remote control system is as follows.Firstly,this thesis analyzed the data transceiver function of visual wireless remote control system;Secondly,studied the key technologies involved in the system in detail,and completed the research on the application methods of the technologies;Thirdly,completed the overall design of visual wireless remote control system,and providing a reference frame for the constructing the system development platform and developing the software;Fourthly,based on the selection of visual wireless remote control system development environment,the visual wireless remote control system development platform was selected and the building process of the system development platform was researched in detail.Lastly,this thesis realized the data transceiver function of wireless remote control system based on internet standard protocol.In addition,this thesis tested the system data transceiver function,and display and analyze the quality of returned video.Based on the embedded system’s good scalability,rich interface,the visual wireless remote control system maximizes the use of system resources and the performance,and has certain fault tolerance and robustness under the pressure of high data transmission. |
