【摘要】 为了减轻地市级气象部门仪器校准人员的工作量,提高了地市级气象部门的校准能力,利用C51单片机技术研发了一款集成CAWS100型自动气象站主采集器的仪器。该仪器能够实现CAWS100型自动气象站采集器与8支PT100温度传感器之间通道的通断,从而达到依次读取8支PT100温度传感器温度值的目的;并通过LCD240128液晶显示屏将读取到的8支PT100温度传感器的温度值进行显示;同时通过AC/DC及降压稳压技术可以直接使用220V交流电供电。更多还原

【Abstract】 In order to reduce the workload of instrument calibration personnel and improve the calibration capability of prefecture-level meteorological departments, an instrument integrated with HY321 automatic weather station main collector was developed by using C51 single-chip technology. The instrument can realize the opening and closing of the channel between the main collector of HY321 automatic weather station and 8 PT100 temperature sensors, so as to achieve the purpose of sequentially reading the temperature values of 8 PT100 temperature sensors. The LCD240128 liquid crystal display will display the temperature values of the PT100 temperature sensors; at the same time, 220 V AC power can be directly used by AC/DC and step-down regulator technology.更多还原
