摘　　要：针对传统阻塞式通信技术在电力物联网硬件资源受限的条件下难以实现可靠高效通信的问题,文章提出基于异步非阻塞框架的电力物联网通信技术。首先,根据异步非阻塞技术原理,基于Rust语言异步编程方法和Tokio异步框架,设计异步非阻塞通信框架,包括客户端连接、服务端连接与监听以及非阻塞的网络数据读写方式等。然后以当前电力远动通信领域中应用最为广泛的IEC 104规约为例,设计其异步非阻塞通信实现方式。最后,对基于异步非阻塞框架实现的通信软件进行一致性测试和性能测试,将测试结果与传统阻塞式通信实现方式对比分析,并通过实际工业园区电力物联网工程应用验证所提技术的有效性和高效性。To solve the problem that traditional blocking communication technology is difficult to achieve reliable and efficient communication under the condition of limited hardware resources of the power Internet of things,a communication technology for power Internet of things based on asynchronous non-blocking framework is proposed.Firstly,according to the principle of asynchronous non-blocking technology,based on the asynchronous programming method of Rust language and Tokio asynchronous framework,the asynchronous non-blocking communication framework is designed,including client connection,server connection and monitoring,and the non-blocking network data reading and writing methods.Then,taking the IEC 104 protocol,the most widely used protocol in the field of power telecontrol communication,as an example,the asynchronous non-blocking communication implementation is designed.Finally,the consistency test and performance test of the communication software based on the asynchronous non-blocking framework are carried out.The test results are compared with the traditional blocking communication method,and the software is applied to power Internet of things of actual industrial parks,which verifies the effectiveness and efficiency of the proposed technology.
