基于si4432的无线自组网抄表系统的设计

Design of Wireless Ad Hoc Network Meter Reading System Based on si4432

无线自组网技术在无线数据传输中占据重要地位,是无线数据传输的关键。基于si4432低功耗的无线自组网络的抄表系统,采用MSP430的主控芯片,能够快速、可靠地传输数据,具有传输距离远、性能稳定、功耗低、性价比高等优势。该网络主从节点,从从节点之间能够自动识别、组网,传输过程能够寻找最优路径;通过多级跳跃传输距离可达10 km以上。通过si4432对前导码同步字的识别机制,应用于模块间的地址识别,保证数据在制定模块间传输,可增大整个网络节点的数量和稳定性。该系统运行对水表数据进行了采集,结果表明该系统能够稳定、快速抄取水表数据,应用于水表等智能仪表抄表领域,可高效实现远程自动抄表。

Wireless ad hoe networks of wireless data transmission technology to occupy an important position,was the key of wireless data transmission.Wireless ad hoc network meter reading system basing on SI4432 use the master chip MSP430. The network master node and slave nodes,the nodes each can automatically identify from among the nodes,it can be able to find the optimal path to transmit network datas. Multi-level jump transmission distance can be 10 km more than.By si4432 preamble sync word identification mechanism,the identification module was applied between the address. Ensure that the data transmission between the specified module,can increase the number of nodes and the stability of the entire network. The system runs on meter data collected,the results show that the system can be stabilized quickly read data. Used in the field of water meters and other smart meter meter reading, remote automatic meter reading can be effiendy.
