基于双模通信模块的用电信息采集系统设计

Design of electrical information acquisition system based on dual-mode communication module

目前单一的电力线和无线用电信息采集通信各有缺陷,难以保证用电采集成功率。融合两种通信技术,基于STM32F107微处理器完成了一种基于双模通信模块的用电信息采集系统设计,提出了一种基于接收信号强度(RSSI)的信道选择算法,研究了双模通信模块的软硬件设计并进行实际测试。测试结果表明,双模通信模块能根据实际环境,依据RSSI选择通信方式,有效可靠传输数据,通信成功率高于单一通信方式。

In view of the fact that the single power line communication and wireless power consumption information collection conmmnication are defective, it is difficuh to ensure the success rate of power collection. Two communication technologies are combined, the electrical information acquisition system based on dual-mode communication module is designed through STM32F107 microprocessor, a channel selection algm＇ithm based on Received Signal Strength？ Indication （RSSI） is proposed, the software and hardware design of dual-mode communication module is studied and tested. The test resuhs show that the dual-mode communication module can select the communication mode according to the actual environment and RSSI, effectively and reliably transmit data, and the communication success rate is higher than that of a single communication mode.
