实时低功耗无线传感器网络设计

摘要

Wireless sensor network is a terminal network of the internet of things, the key of sensor data collection. A new type of wireless data collection system based on SI4432 produced by silicon laboratories was introduced. This system periodically collected sensor data through time-sharing sampling method to reduce power consumption and periodically gave alarms to ensure real-time communications. The test results indicate that the system can effectively monitor the data on sensor data collection terminal, and has long transmission distance, high stability performance, low power consumption and high performance price ratio.%无线传感网络是物联网的终端网络,是传感数据汇集的关键.基于无线芯片SI4432设计的新型无线传感器网络,采用分时采集方法周期性地对传感器数据进行采集,以降低功耗.运用周期性报警方法实现实时目的.结果表明该系统能够有效地监控数据采集点的数据,具有无线传输距离远、性能稳定、功耗低、性价比高等特点.
