Abstract
In view of problems that existing mine positioning equipment embedded program upgrade method needs to establish physical connection and there’s no programmable wireless upgrade protocol for small embedded devices, a wireless software upgrade method for mine positioning equipments was proposed. The method adopts wireless broadcast transmission mode and one-to-many network mode to implement batch wireless IAP (In-Application Programming) upgrade of mine positioning device, thereby improving convenience and efficiency of upgrade. The experiment results show that the overall upgrade success rate of the method is positively correlated with distance, and the success rate is high within 10 m. The method provides an effective way for upgrading of a large number of mine positioning equipments.
