Technical Field

The invention relates to the technical field of meteorological monitoring, in particular to a wireless transceiving system of a meteorological station of an electric power system.

Background

Based on the monitoring demand for local meteorological information, domestic converter stations and transformer stations are generally provided with small meteorological stations, and based on safety considerations, the small meteorological stations are generally arranged on the roofs of office areas far away from transformer equipment areas. However, personnel in the converter station and the transformer substation generally concentrate on a monitoring duty room in an equipment area, the monitoring duty room has a certain distance with an office area, and under the condition of severe weather, the personnel are difficult to go to a small-sized weather station installation point to check weather information. At present, the common practice is to transmit weather information from a workstation of a weather station to a computer of a monitoring duty room by using an ethernet or an RS485 bus, and to check the weather information by using a computer client in the monitoring duty room. When the monitoring on-duty room is far away from the meteorological station, the problems of high construction difficulty, high cost and the like exist in laying the RS485 bus, and when the monitoring on-duty room or the meteorological station changes places, the monitoring on-duty room or the meteorological station needs to be laid again, so that the scheme has poor flexibility.
