The Application Of Bluetooth Technology In The Hardware-In-The-Loop Simulation System

The table is a 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 perfomance of UAV 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.Bluetooth,as a new short-range wireless communication technology,is a reasonable and feasible scheme in this condition.In this thesis,firstly,the main protocols and their functions,the application profiles of Bluetooth technology are introduced.the HCI protocol is analysized emphasesly;secondly,the 4-channel±10V analog to digital conversion (A/D) Bluetooth adapter,4-channel±10V digital to analog conversion (D/A) Bluetooth adapter,RS232 serial port Bluetooth adapter are developed.the hardware and software of them are realized and test ;thirdly,the test tool software for Bluetooth adapter is designed.the displaying and saving of data with VC++6.0 Multithread in PC is completed,then the wireless serial port communication between PC and Micro -controller Unit (MCU) is implemented,the data results of those adapters are acceeded;finally,the Bit-Error-Rate testing software of Bluetooth communication system is designed,and the Bit-Error-Rate test results of Bluetooth adapter in labortary are acquired and illustrated also.It is proved that Bluetooth technology meets the performance demand of the simulation system from the conclusion.The Bluetooth adapter system provided great value for the advanced exploiture of wireless communication simulation system of the UAV.
