低功耗无线温湿度监测系统设计

Low power wireless temperature & humidity monitoring system

以凌阳16位单片机-SPCE061A为核心,利用nRF401无线收发芯片、USB接口芯片PDIUSBD12和YX-HT-300U温湿度模块,设计了一个低功耗无线温湿度监测系统。该系统由一个中心站和多个基站组成。其中基站采集温度、湿度数据,之后将其通过无线收发芯片向中心站传输,并能接收中心站发来的控制命令,使中心站能通过SPCE061A单片机对基站实行远程控制;中心站接收基站传来的数据,并通过USB接口将其传入计算机中进行分析。该系统利用软件对无线收发芯片工作状态进行监控,提高了系统的可靠性。实践证明该系统体积小、功耗低、精度较高、数据传输可靠性高、功能易扩展,适于林区、仓库等多种应用领域。

A low consumption wireless temperature＆/humidity monitoring system, which is based on the single chip- SPCE061A, the single chip RF transceiver/receiver-nRF401, the USB interface chip-PDIUSBD12 and the temperature/ humidity module-YX-HT-300U, is introduced in this paper. This system is composed of one central station and several base stations. The datum of temperature and humidity are collected, then are transmitted to the central station from the base stations which is monitored by the central station via the wireless transceiver/receiver-nRF401. The datum are received from the base stations to central station, then are transmitted to the computer where they are analyzed via the USB interface. The status of the wireless transceiver is monitored by the system software which made its reliability improved. The system, which is low consumption, cabinet, high precision, high data transfer reliability and easy extended function,can be applied in many regions such as forest and depots and etc.
