Automatic Dependent Surveillance Broadcast Equipment System Design

摘要:

随着多旋翼无人机日益广泛的应用,其监视能力的薄弱也日渐显露,增强其自主监视能力是实现无机自动化的重要手段,为此,设计了一套基于MSP430F4152的小型广播式自动相关监视设备,可使多旋翼无人机具有自主监视能力;首先,基于现有的广播式自动相关监视技术,对嵌入式系统进行优化设计,然后,设计了以MSP430F4152微控制器为主控芯片的硬件部分,通过ATGM331C模块获取位置信息与时间同步信号,并利用nRF24L01+模块进行无线数据传输,最终在J204A显示屏上显示本机信息与远程数据;软件部分针对电池驱动的硬件做了优化设计,参考UAT数据链设计了本系统的工作时序,利用Asterix Category 021协议设计了本系统的报文格式,最后对文中方法进行实验测试,结果表明了文中系统能实现主监视,是一种可行的方法。

Abstract:

with the application of multi rotor UAV is increasingly extensive,its weak monitoring capacity has become evident. Self monitoring ability of multi rotor UAV is not a very important link in computer automation. Therefore,a small radio type MSP430F4152 automatic dependent surveillance equipment,which can make the multi rotor UAV with independent monitoring ability. This paper optimized the existing automatic dependent surveillance broadcast technology of the embedded system. The hardware part takes MSP430F4152 micro controller as main control chip,acquire the position information and time synchronization signal through the ATGM331C module,and wireless data transmission by nRF24L01+ module,and finally display the machine information and remote data in the J204A display. The software part do optimization design of the battery powered hardware,refer to the UAT data link design time sequence of the system,using Asterix Category 021 protocol and design the system message format. The experiment is implemented to test the proposed method in this paper,and the result shows it can achieve automatic monitoring,so it is a feasible method for UAV.
