摘要

针对开放式远程实验平台的高并发、实时性、可靠性和安全性需求,设计并实现了一种高并发访问的远程实验通信方案。该方案能够实时连接大规模传感器网络,具有实验仪器与用户并发访问、实时可靠消息传输、网络安全控制和仪器安全保障功能,能有效提高远程实验的通信性能。在模拟大规模用户实时并发访问的情况下进行性能测试,测试结果表明该方案不仅能满足实验通信的并发需求,还能有效确保消息的实时可靠传输和安全控制,具有较高的应用价值。
        To meet the requirements of open remote experiment platform for high concurrency, real-time, reliability and security, a remote experimental communication scheme is designed and implemented, which is suitable for high concurrent access of users. The proposed scheme can connect large-scale sensor networks in real time and has the functions of concurrent connection of experimental instruments and users, real-time and reliable message transmission, network security control and communication failure processing, which can effectively improve the communication performance. The performance test is carried out under the condition of simulating real-time concurrent access of large-scale users. The test results show that this scheme can not only meet the concurrency requirements of experimental communication, but also effectively ensure the real-time reliable transmission and security control of messages, which has high application value.
