| 摘 要： | 针对车间实时数据采集组网模式技术中轮询制信道利用率低的问题，提出一种基于时分多址技术的RF433M通信方法，在实际项目中制定射频组网主动发送机制。与其他射频组网轮询制的比较结果表明，基于时分多址技术的主动发送机制无论是在通信速率、通信稳定性还是在组网灵活性上，性能都更优。该技术能更好解决车间的射频组网同步问题，有效提高车间无线网络的信道利用率和通信速率。

| Abstract: | This paper proposes a kind of TDMA technology of RF433M communication against the low utilization rate of turn-requiring network model in real-time data acquicition. Compared with traditional RF turn-inquiry mechanism, a initiative mechanism of RF network is made according to this technology in project. The results show that the technology performs better effect in transmission rate, stability and flexbility of network,it can solve the problem of synchronization in wireless network and can improve the utilization rate and data rate of the network more effectively. |
