Description
技术领域technical field

背景技术Background technique
目前，各自动气象站采用的雨量计主要是单一的翻斗式雨量计，翻斗式雨量计的容量很小，一般允许的最大降雨强度为4mm/min，所以翻斗雨量计不适合计量强降雨过程；并且强降雨的水流势能很大，极容易将翻斗式雨量计的翻斗打翻，使其在未注满水时提前翻转，因此造成较大的测量误差。目前的雨量计，其本身的各个部件不具备状态监控和数据质量控制的能力，不能检测雨量计的各个部件是否工作正常，也就不能保证雨量计的可靠性和准确性。另外，虽然雨量计的通信方式可以是各式各样的，但现有的雨量计一般采用有线的方式传输降雨量数据，布线复杂，不易扩展。At present, the rain gauges used by automatic weather stations are mainly single tipping bucket rain gauges. The capacity of the tipping bucket rain gauge is very small, and the maximum allowable rainfall intensity is generally 4mm/min, so the tipping bucket rain gauge is not suitable for measuring heavy rainfall. Moreover, the potential energy of the water flow of heavy rainfall is very large, and it is very easy to overturn the tipping bucket of the tipping bucket rain gauge, causing it to turn over in advance when it is not filled with water, thus causing a large measurement error. The current rain gauge does not have the ability of status monitoring and data quality control for its various components, and cannot detect whether the various components of the rain gauge are working normally, so the reliability and accuracy of the rain gauge cannot be guaranteed. In addition, although the communication methods of rain gauges can be various, the existing rain gauges generally use wired methods to transmit rainfall data, and the wiring is complicated and difficult to expand.
