Research On Wireless Transmission And Application In Simulation System

The three-axis table is an important device in the Hardware-In-The-Loop Simulation System,and it simulates the flight of Unmanned Aerial Vehicle so as to achieve flying parameters from those sensors. The signals of sensors in the table are transmitted by many cables previously,thus it confines the movement range of the three-axis frameworks. As the performance of Uumanned Aerial Vehicle become complicated,the signals cables are replaced by wire rings in some tables,but it brings many difficulties and unreliable factors for the simulation table's design also.In this thesis,firstly,the protocol framework of Blutooth technology is introduced. Baseband Protocol,Link Manager Protocol,Logical Link Control and Adaptation Protocol,Service Discovery Protocol and Serial Port Emulator Protocol are analysized emphasesly. Secondly, the 4-channel±10V analog to digital conversion Bluetooth adapter,the 4-channel±10V digital to analog conversion Bluetooth adapter and RS-232/RS-422 serial port Bluetooth adapter are developed,then the hardware and the software of them are realized and tested. Thirdly,the test system of the Buletooth adapter is designed. The data is acceeded in the stimulation condition and the transmission speed and the Bit-Error-Rate of the Bluetooth adapter are tested,then the test results are acquired and illustrated. Finally,the difference between Bluetooth and IEEE802.11b is introduced and the problem in mixed environment of Bluetooth and IEEE802.11b is investigated,then the solution scheme is provided.It is proved that Bluetooth technology meets the performance demand of the simulation system from the conclusion.
