ABSTRACT:
A weather station display system displays weather data on a video monitor, TV receiver or other raster screen display. The weather data is derived from a weather station having multiple weather parameter sensors or transducers for measuring weather parameters and generating electrical signals representative of the measured values of the weather parameters. The electrical signals are conditioned and converted to digitally coded weather data. A microprocessor periodically samples and stores the digitally coded weather data and transfers weather data to a screen memory for raster scanning onto a raster screen display. The microprocessor also loads screen display format data including a main screen display format to the screen memory from program and screen data memory. A light pen coupled to the raster controller permits interrogation of character locations for selectively modifying displayed weather data. The program components stored in program memory direct updating weather data, user interactive light pen recall of maximum and minimum weather data, and interactive assembly of user messages.
