In order to improve the environmental quality of chemical heavy industrial zones and strengthen the meteorological monitoring in chemical heavy industrial zones, this paper studies the meteorological automatic monitoring intelligent system in chemical heavy industrial zones. This paper proposes the data acquisition performance index of monitoring system according to the production and environment conditions of chemical heavy industrial zones, and designs the functional requirements and performance of GPRS features, network scheme and system software. Then, the simulation experiment is carried out on the basis of the designed system. The study shows that the forecasting results of meteorological data are consistent with the measured ice thickness, which can meet the requirements of the power line ice forecasting. It can be seen that the system can meet the needs of meteorological automatic monitoring with good performance in industrial meteorological monitoring.
