Abstract:
This paper proposes an implementation scheme of wireless upgrade firmware program based on UWB and ZigBee technologies. This method adopts one-to-many networking mode and infinite loop multi-broadcast mechanism to realize the location card batch wireless upgrade, which improves the speed, concurrent capacity and efficiency of wireless upgrade. The test results show that the concurrent number of locating card in batch upgrade is not limited. Within the coverage area of 100 meters, 95% locating cards are successfully upgraded once, 5% locating cards need to wait for two cycles, and the wireless upgrade time is less than 5 minutes. Therefore, this method provides a fast, reliable and convenient wireless upgrade way for a large number of locating card upgrade firmware programs.
