Design of Automatic Meteorological Data Acquisition System Based on ARM and CAN Bus
Aimed at the current situation that the domestic automatic meteorological data acquisition system is almost based the use of foreign products, a design method of multi-channel meteorological data acquisition system was given which based on ARM and CAN Bus. In the design, it fulfills the acquisition requirements of the analog signals, digital signals and intelligent sensor data through a combination of hardware and software technologies. In order to improve systems real-time answering capability and multi-task processing capability, it is used main collector + external bus + sub-collector + sensors + peripheral equipment in structure design of hardware. At the same time, it is transplanted Linux operating system to improve the reliability and scalability of system. It is translated Linux operating system to embedded processor, and making use of Internet to send meteorological data in Linux operating system. Then the complicated cabling project could be omitted, the data were sent without PC, and in favor of constituting Large-scale meteorological monitoring network.
