摘　　要：JJQ1型信号模拟器是中国气象局下发到各省的功能较为完善的自动气象站信号模拟器,从配发各省至今已有3年的时间了,尚没有省份使用该信号模拟器正式开展采集器校准工作,导致这种情况的原因是多方面的:包括校准使用的软件不合理、各通道(尤其是模拟信号通道)之间会产生信号干扰导致校准工作耗时长效率低、模拟信号随环境温度漂移大、不能兼容多数常用的数据采集器等。通过理论及试验测试分析了以上的问题,给该信号模拟器使用者和设计研发人员提出了建议和意见。The JJQ1 signal simulator, which has relative perfect functions in the provincial level laboratories, has been used for three years, but there is no reporting about using the signal simulator to calibrate collectors of automatic meteorological stations. There are complicated factors for this phenomenon; for example, the calibration software is not reasonable, and signal interference among channels （especially the analog channel） results in too long calibration time and low efficiency; as well as the analog signal drift with the environmental temperature; it is not compatible with all common data collectors. These problems are analyzed by the theoretical and empirical methods, and some suggestions and opinions are put forward for signal simulator users, as well as research and development personnel.
