Abstract:

As for the charateristics and the existing problems of the electrical equipments under the mine, a multifunctional mine electrical equipment protection device based on embedded systems is designed. According to the general requirements of the design proposal, this paper adopts S3C2440, based on the ARM920 core, as the processor, combines the embedded operating system Linux, meets the capability requirements of the multifunctional electrical equipment protection device and achieves the design target of the protection device by designing the system hardware structures ,software programming and testing. Under the operations of the clientside software and the serverside software used for monitoring host, the fast and reliable telecommunication between them comes true. The result of the experiment shows that the use of the protection device will improve the flexibility, utility, interactivity of the mine electrical equipment protection device greatly, cuts down the work amount and decreases the working strength in the maintenance of relative devices.
