| 针对现有自动气象站信号模拟器温度通道存在误差大、难以兼容不同型号采集器的问题，分析了CAWS600、ZQZ系列自动气象站采集器的测温原理，利用不同型号的采集器对JJQ1型信号模拟器的温度通道进行了测试，指出了测试数据存在抖动的原因，提出基于采集器的四线制测温原理，以定制的高精度、极低温漂电阻为核心，利用信号继电器构造四线制网络，辅以软件补偿，能适应不同型号的采集器的温度通道改进方法。最后，分别利用采集器和高精度万用表对改进的温度通道进行了测试，数据表明模拟的温度最大误差为±0.03 ℃，对应电阻的最大误差为±12 mΩ，满足行业标准QX/T 346—2016《自动气象站信号模拟器》，为自动气象站信号模拟器的优化提供了参考。 |

| Aiming at the perspectives of big errors and difficult compatibility of existing automatic weather station signal simulator, this paper has analyzed the temperature measurement theory of CAWS600 and the series of ZQZ automatic weather station collectors. In this paper, the temperature channel of JJQ1 signal simulator is tested by using different types of automatic weather station collectors, and the reasons for fluctuations of test data are analyzed. Based on the temperature measurement principle of four wire system, the high precision and extremely low temperature drift resistance, the four wire network is constructed by signal relay, and the software compensation is adopted. It can be adapted to the temperature simulation scheme of different collectors. At last, the modified temperature channel is tested by collector and high precision multimeter. The experimental data show that the maximum error of the simulated temperature is ±0.03 ℃, the maximum error of the corresponding resistance is ±12 mΩ. It meets the industry standard QX / T 346 2016 “automatic weather station signal simulator”, and provides reference for the improvement of the automatic weather station signal simulator. |
