通用型探空仪基测箱

针对由于目前我国高空气象探测使用的探空仪基测箱不通用,而引起的基测箱配发重复、资源浪费等问题,首次提出设计一种通用型探空仪基测箱。采用低功耗、高精度的传感器测量气温、气压,通过DSP完成各气象要素的采集、计算和电路控制,使用FPGA完成逻辑、接口和显示控制等功能,设计电源变换电路为8种型号探空仪提供工作电源。通过测试表明通用型探空仪基测箱测量精度满足设计指标要求,可为多型探空仪提供基值测定功能,具有广阔的推广前景。

General type basic value measurement box for sonde

Since the basic value measurement box for radiosonde currently used in Chinese high？altitude meteorological sounding is not common,which causes repeated allotment and waste of resources,the design of a general type basic value mea？surement box for sonde is proposed in this paper. The low power consumption and high precision sensor are used in the box to measure the atmospheric temperature and pressure. Acquisition and calculation of the meteorological factors,and circuit control are accomplished by the aid of DSP. logic,interface and display control functions are completed by FPGA . A power conversion circuit is designed to provide power supply for 8 models’radiosondes. The testing results show the accuracy of the general type basic value measurement box for sonde can meet its design requirements,provide basic value measurement for multi？type radio？sondes,and has a broad prospect for promotion.
