Design of rainfall gield calibration system based on Cloud-Terminal
A rainfall on-site calibration system based on embedded technology and Internet of Things technology has been designed,consisting of a provincial-level rainfall calibration management platform on the cloud end,a rainfall calibration communication module,and a JJS1 type tipping bucket rain sensor calibrator.The system can measure the rainfall count of the rain sensor and use 4G+MQTT protocol to connect real-time data transmission and management for verification between provinces and cities.The verification results are uniformly judged and fed back in real time by the"cloud"end,avoiding the influence of improper operation by business personnel.This system can effectively improve the efficiency,real-time performance,and quality of rainfall observation data in on-site calibration work.In addition,provincial-level business management departments can use the provincial-level rainfall calibration management platform to real-time understand the calibration status of various stations and improve their business management capabilities.This technical solution is economically reliable and has the potential for promotion,which will help improve the management mode of graded meteorological equipment calibration at the provincial,regional,and station levels.
