| 摘 要： | 针对基于Zigbee技术的无线抄表系统成本高、抗干扰能力弱、通信距离受限的缺点，提出了一种扩频通信与GSM技术相结合的远程无线抄表系统设计。结合低功耗的射频收发芯片sx1278，设计了汇总节点、中继节点以及水表采集节点硬件电路，确定了通信的数据帧结构，制定了相应的组网算法。在抄表区域中采用抗干扰能力强的扩频通信技术进行无线抄表，在远距离通信中采用GSM技术将汇总的水表数据传送到控制中心，整个抄表系统具有低功耗、抗干扰能力强、自组网特点，能够实现远程控制无线自组织组网抄表。测试结果表明，设计的系统能够实现稳定的自组网，具有较高的抄表成功率、较好的性能和广泛的应用前景。

| Abstract: | In view of high cost, the weak anti-interference ability and the limited communication distance based on Zigbee wireless meter reading system, a set of wireless meter reading system design is proposed combined with spread spectrum communication and GSM technology in the paper. The designed system can realize remote control wireless self-organizing network meter reading by using the spread spectrum communication in the meter reading area and the GSM technology in remote area, having the characteristics of low power consumption, strong anti-interference ability and self-organizing network. Experimental results show that the designed system can realize the stable ad-hoc network and has good properties and application prospects. |
