Abstract:
     The automatic meteorological station is composed of sensors, data acquisition units, single chips and designed software / hardware. Through CAN field bus, sensors are connected to data acquisition units. CAN field bus include three layers: sensor layer, field control layer and display control layer. Sensors constitute the sensor layer. The field control layer includes each sub acquisition unit and main acquisition unit. Structured from single chip, and designed software / hardware each sub unit and main unit possesses CAN interface. Through sensor and CAN bus, each sub acquisition unit is connected to main acquisition unit. Through main node, local and remote RS-232 ports, the display layer is connected to Internet so as to transfer weather information for extensive area. Features are: transmission distance of meteorological data reaches to 10km with reduced error rate.
