采用UDP通信协议实现基于VxWorks的阵列天线主控系统与各分系统之间的多节点通信；在应用层中设计了通信协议，保证通信双方可以正常通信；同时，设计了缓冲机制，用以存储收发的命令，保证信息在传输过程中不丢失，使命令任务能够有序正常的执行。实验结果表明，该协议及缓冲队列可以有效的实现阵列天线主控系统与各分系统之间的多节点通信。

In order to realize the multi-node communication between the main control system of array antenna and the other systems based on VxWorks, a communication protocol based on UDP is used in this paper. In the application layer, a unified communication protocol is designed, which can ensure communication between both parties. At the same time, the buffer mechanism is designed to store the command and ensure that the information is not lost during the transmission, so that the order task can be executed normally and orderly. Experimental results show that the protocol and buffer queue can achieve the multi-node communication between the main control system and the other systems.
