Research On The Technology Of Telemetry And Remote Control Radio Station On Aircraft

The continuous development of electronic science and wireless communication technology has brought great development space for missile measurement and control technology in the field of space science and technology.As the key terminal of the aircraft,the missile wireless measurement and control radio provides the corresponding scientific basis for the performance analysis and fault detection of the missile by obtaining the electrical parameters of the missile’s normal operation and flight test.Therefore,the research content of this topic is of great significance to the construction of China’s space defense industry.The equipment required for the realization of the traditional missile wireless measurement and control technology includes the acquisition and coding device,transmitter and receiver.But with the aircraft becomes more and more versatile,the electronic devices above the aircraft are more and more.As a result,the installation space left for the measurement and control equipment will become narrow,and the interference factors in the electromagnetic environment will become more complex.Based on the above-mentioned problems,a missile wireless measurement and control radio equipment that combines the acquisition and coding device,and the wireless transceiver into one.Through modularization,miniaturization and digital improvement of the measurement and control equipment,the goal of reducing the space size occupied by RF electronic circuits and reducing the footprint of the equipment and reducing the total weight of the aircraft^[1].And in order to ensure that the missile wireless measurement and control radio can be operated normally and stably in the actual installation environment,also use the radio equipment to carry out wireless pull-out test and high-low temperature cycle test and random vibration test.The specific content of this topic is divided into three parts,first of all,the design and implementation of wireless measurement and control radio terminal board card of the various parts of the circuit,including the RF front-end unit,the upper/lower variable frequency processing unit,the baseband processing unit and the power supply unit four parts.Then,the software algorithm of wireless measurement and control radio station is designed and implemented,including SPI interface configurator of radio frequency transceiver,UDP protocol driver of Ethernet controller,ADC acquisition program,RS422 serial communication program,frame processing procedure and frame synchronization procedure.Finally,the overall functional index test was carried out on the hardware board of the wireless measurement and control radio station.Through the above series of research work,the final implementation of the missile wireless measurement and control radio can work at 512kbps information rate,the reception sensitivity of the radio is better than-90dbm.And the radio equipment can guarantee the communication quality at 5Km communication distance,the error rate of meeting the scheme design is not greater than 10^-5.The results show that the whole radio station has the characteristics of full duplex,miniaturization,strong anti-jamming ability and high communication quality,and has certain engineering practical value,which can be widely used in the field of space military radio testing and control system.
