保证冰情检测系统能够在极低温野外环境下能够正常工作是水文测报应用领域的一个难题.结合“基于空气、冰与水物理特性差异的冰情检测系统”特点设计了低功耗冰情检测系统保温专用电路,介绍了低功耗加热、保温、智能温控以及对蓄电池的电路处理方法,整个系统在野外环境下,通过40W太阳能板供电电源供电,便可实现在无人值守的低温恶劣环境下长期连续自动工作.2013.12.23-2014.4.3该系统在在黑龙江漠河段河道连续进行了野外现场连续数据采集试验,系统保温效果良好,数据采集性能稳定可靠,对一般的野外冰情监测系统设备冬季保温具有参考价值. To ensure that the ice detection system can work well in extremely low temperature field is a difficult problem in the field of hydrological data detection.Combined with the characteristic of ice detection system based on the physical characteristics of air, ice and water, In this paper, we introduce the low-power heating, thermal insulation, intelligent temperature control and circuit processing methods for the battery. The whole system in the field environment, through the 40W solar panel power supply, can be realized in the unattended Long-term continuous automatic work under the harsh environment of low temperature.2013.12.23-2014.4.3 The system continuously conducted continuous field data acquisition test in the Mohe section of Heilongjiang Province, the system has good heat preservation effect, the data acquisition performance is stable and reliable, and the general field ice Winter weather monitoring system equipment has a reference value.
