[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.
