【摘要】 针对目前各地自动气象站两种地表温度的测量方式,即:四支传感器组合模式和单支传感器测量模式共存的现状,文章通过对地温传感器的测量技术以及信号采集原理的分析,探讨了一种可以将四支温度传感器化简成为单只温度传感器的方法。经过改进后的测量方式,符合中国气象局2003版地面气象观测规范的要求,保证了自动气象站地温测量方式的一致性和可比性。同时,该方式会有效地降低地温传感器的隐性故障机率,减少自动气象站的维护成本,并且易于推广和应用。更多还原

【Abstract】 Presently,there are two surface temperature measurement methods: the four sensor combination mode and single sensor mode.Through the analysis to the measurement mode of surface temperature sensor and the signal gathering principle,but also discusses measuring technique of using the single temperature sensor to substitute four temperature sensors.Besides,the improvement of measurement mode meets requirement of surface weather observation standard of 2003 edition for Chinese Meteorological Bureau.It has guaranteed uniformity and commensurability of the measurement mode of surface temperature.Meanwhile it cuts down breakdown probability of temperature sensor and reduces the maintenance cost of automatic weather station,which is easy to promote the application.更多还原
