摘要
设计了基于无线传感网络自动气象站的手持式校准器,主要包括ZigBee协议栈处理器为核心的无线传输功能模块、单片计算机、液晶显示模块、NANDFlash存储器、时钟电路等。详细介绍了手持式校准器的软硬件设计方法,实现了对无线传感网络自动气象站的被校准传感器所发送数据的无线接收、显示和存储,通过与标准器读数比对并发送校准命令来校准现场传感器的零点及满量程,同时发送打印数据给无线打印机,实现校准结果的无线打印。
A handheld calibrator based on wireless sensor network of automatic weather stations is designed,mainly including a wireless transmission module using ZigBee protocol stack processor as the core,single-chip computer,a LCD module, NANDFlash memory,clock circuit,etc.The method of hardware and software design for the handheld calibrator is introduced in detail to realize the wireless receiving,display and storage of data sent by calibrated sensors of wireless sensor network in automatic weather stations.By comparing with readings of standard devices and sending calibrating commands, it is realized to calibrate the zero and full range of field sensors,meantime,send printing data to the wireless printer to achieve wireless printing of the calibrated results.
