摘要
针对某传感器测试系统数据传输的需求,提出了实时性较强的UDP传输方案。在明确测试系统构成的基础上,探讨了嵌入式设计领域UDP传输实现的2种方案,详细介绍了设计中以太网的接口电路和与UDP相关协议的开发,并给出了嵌入式控制器中有限存储资源分配使用的方法与算法。最后结合具体问题,延伸了模块中的软件与硬件设计。实际应用表明,基于UDP的传输方案具有数据传输效率高的特点,适用于远程数据的传输。
A scheme of UDP transmission was introduced to address data uploading in a sensor measurement system. On the base of getting acquainted with structure of system,this paper researched several design scheme of UDP implementation, and details design of network interface and development of protocol relevant to UDP, then presented ideas and algorithm on allocation of limited RAM in embedded controller. Combining with specific problem, this paper extended design method of software and hardware. Application shows that UDP transmission meet requirement and is suitable for remote data transmission.
