Automatic data logger switching apparatus for automatic weather system

摘要

PURPOSE: An auto-switching device of data collectors of an automatic weather system is provided to prevent the system from stopping by arranging extra same data collectors and auto-switching a wrong data collector to a normal data collector in case that any one of the data collectors is wrong. CONSTITUTION: The automatic weather system includes a plurality of sensors for sensing weather conditions, an interface(50) for converting signals from the sensors to digital data, data processing parts(22,22') for transmitting signals from the interface as a weather information data, modems(24,24') for transmitting the weather information data to the outside and power supplies(26,26') for supplying a power to the data processing part and the modem. In the automatic weather system, a first data collector(20) and a second data collector(20') are arranged. A switching unit(60) is provided for generating a switching signal to auto-switch a wrong data collector to a normal data collector in case that any one of the data collectors in operation is wrong.
