| 摘 要： | 针对弹载记录设备搜寻困难的问题，设计了一种基于低功耗单片机MSP430的无线信标机系统。该系统以单片机为主控单元，接收GPS模块定位信息，以频率合成技术为依托，使用DDS芯片对定位数据进行高频BPSK调制，并通过对电源模块的灵活控制，降低系统功耗、延长工作时间。实测数据表明，该信标机输出的调制信号频率可达到400MHz,功率可达到1.92W，信标机的工作时间为24h,能满足记录器回收要求。

| Abstract: | Aiming at the difficulty of searching for on-board recording equipment, a wireless beacon system based on low-power MCU MSP430 is designed. The system takes single chip microcomputer as the main control unit, receives GPS module location information, and uses the DDS chip to make high frequency BPSK modulation for positioning data based on the technology of frequency synthesis., and through the flexible control of the power supply module, reduce system power consumption and prolong working time. The measured data show that the frequency modulated signal produced by the beacon can reach 400MHz, the power can reach 1.92W, and the working time of the beacon is 24h,can meet the recorder recycling requirements. |
