UDP通信简单且支持组播，在工程中得到广泛应用，但是传输是不可靠的。为了解决传输可靠性问题，经常采用多数判决机制或应答确认机制，但这些机制都或多或少地增加了程序的复杂性，带来了一些其他的问题，比如延时和不稳定等。针对这一问题，提出了对帧序号进行判决的重发机制，对接口格式及收发双方的程序逻辑进行了简要介绍。经过工程实验验证，该方法简便有效，切实可行。

The UDP communication is widely used in engineering, it is simple and supports multicasting, but has unreliable transmission. In order to solve the transmission reliability problem, the majority judgment mechanism or the ARQ mechanism is often used, but these mechanisms more or less increase the procedure's complexity, which causes some other problems such as delay and instability. Aiming at this problem, this paper proposes a resending mechanism for judging the frame number, briefly introduces the interface format and the program logic of transmitter and receiver. The engineering experiment results show that this method is simple, effective and feasible.
