摘　　要：为降低温室数据采集器误差水平。通过分析采集器的硬件结构,依据误差分析理论综合计算温室数据采集器光照强度、土壤湿度、环境湿度理论误差值。选择各参数高精度温室数据采集仪表对比测量,计算采集器的实际测量误差,然后参考理论误差进行误差插值校正,调整温室数据采集器光照强度、土壤湿度、环境湿度的误差到理论误差范围之内。In order to reduce the greenhouse data acquisition error level,theoretical error values of light intensity,soil humidity,environment humidity of greenhouse data acquisition system were calculated by analyzing the collector＇s hardware structure based on the error analysis theory.Then high-precision data acquisition instrument was chosen to measure the actual error values of the data collector.Finally,the actual error values of light intensity,soil moisture,humidity measurement of the collector were adjusted by interpolation correction to make error values be less than the theoretical error level.
