Background
In order to enhance rainfall forecast accuracy, implementation to eliminate water service for the drainage group using the city waterlogging weather warning service system refinement. The City Meteorological Bureau around constantly adding automatic weather stations, in order to improve the forecast accuracy.
Automatic weather station is a device that can automatically observation and storage of meteorological observation data, which is composed of a sensor, collector, GPRS/CDMA 1X network communication interface, system power supply, real-time monitoring on-site meteorological conditions; in addition, some remote area power supply by the solar battery.
Automatic weather stations are generally distributed in the open field unattended, on the one hand need to bear high temperature, frost, fog, dust, lightning and other harsh environment. On the other hand, to establish a reliable GPRS/CDMA 1X and meteorological monitoring center network connection.
