Research On Remote Control Technology Of Aircraft Control System Based On Network

With the growing development of network control technology,network based control application has become wider and wider,which has become the focus in automatic control field currently.Network based control system can take advantage of the supplies and intelligence resource in the local end and implement operation and control to the equipment in the remote site effectively.Therefore the research on computer network control technology has a significant application value.This paper mainly studies the remote control technology of network-based for aircraft control system.The remote control terminal of the aircraft control system transmits the frequency,the power,the number of times and the instruction information accurately and quickly to the local terminal according to the flight condition of the aircraft.The local control system accurately executes the instruction so that the aircraft can follow the instructions Information for safe operation.This paper has developed a network-based remote control software for remote control system and local software.Remote management software is based on VC ++6.0 development environment,the use of multi-threaded and socket technology development.Taking into account the requirements of fast and accurate transmission of information and research,compare the advantages and disadvantages of UDP and TCP,and finally select the UDP as the transmission protocol of this project.In the efficient transmission at the same time through the local end of self-test,instruction confirmation,re-issued instructions such as transmission to make transmission more accurate.In addition to receiving remote instructions,the system can independently control the local side and develop a local-side application that can independently set the transmission frequency,power,frequency,and instruction code information.Set the information through the CPCI bus to complete the Industrial computer and the board between the data transmission,the use of FPGA chip to complete the digital baseband signal modulation and demodulation,through the RF circuit to achieve RF signal transmission and reception.The actual test shows that the system has reached the expected requirements for accurate and fast transmission of control information through the network or local terminal.The research results of this paper have important theoretical and reference value for the future study of network-based aircraft control system.
