The design of 1-wire net meteorological observatory for 2.4 m telescope

The weather is an important factor to affect astronomical observations.The 2.4m telescope can not work in Robotic Mode without the weather data input.Therefore it is necessary to build a meteorological observatory near the 2.4m telescope.In this article,the design of the 1-wire net meteorological observatory, which includes hardware and software systems,is introduced.The hardware system is made up of some kinds of sensors and ADC. A suited power station system is also designed.The software system is based on Windows XP operating system and MySQL data management system,and a prototype system of browse/server model is developed by JAVA and JSP.After being tested,the meteorological observatory can register the immediate data of weather,such as raining, snowing, and wind speed.At last,the data will be stored for feature use.The product and the design can work well for the 2.4m telescope.
