The invention discloses an ADS-B (Automatic Dependent Surveillance-Broadcast) data transmission method and system based on Beidou short message communication, and the method comprises the steps: detecting a network state, and transmitting civil aircraft situation information and general aircraft situation information received by an ADS-B ground station to a server through a network if the network is normal; when the network is abnormal, detecting a signal state of a Beidou short message communication link and a short message communication service support state; when the signal state of the Beidou short message communication link is normal and the Beidou short message communication link supports a short message communication service, screening out the general aviation aircraft situation information from the ADS-B ground station; according to a preset Beidou short message reporting protocol, encoding the screened general aviation aircraft situation information to obtain a Beidou short message; and transmitting the Beidou short message to a server through the Beidou short message communication link. According to the invention, the situation information of the general aviation aircraft can be transmitted to the server in real time in any network state, and the high real-time requirement of monitoring the general aviation aircraft is met.
本发明公开了基于北斗短报文通信的ADS‑B数据传输方法及系统,方法包括:检测网络状态,若网络正常,则将ADS‑B地面站接收的民航飞机态势信息和通航飞机态势信息通过网络传输到服务器;当网络异常时,检测北斗短报文通信链路的信号状态和短报文通信业务支持状态;当所述北斗短报文通信链路的信号状态正常并且支持短报文通信业务时,从所述ADS‑B地面站中筛选出所述通航飞机态势信息;根据预设的北斗短报文上报协议,对筛选的所述通航飞机态势信息编码,得到北斗短报文;通过所述北斗短报文通信链路将所述北斗短报文传输至服务器。本发明实现了在任何网络状态下,都能够将通航飞机态势信息实时传输至服务器,满足了监视通航飞机的高实时性要求。
