基于广播方式的无线软件升级方法

    Wireless software upgrade method based on broadcast mode

    • 摘要: 提出了一种基于广播方式的无线软件升级的实现方案,该方法采用一对多的组网模式和无限循环多次广播机制,实现定位卡批量无线升级,提高了无线升级的速度、并发容量和效率。试验结果表明:定位卡批量升级的并发数量不受限制,在100 m覆盖范围内,95%定位卡一次性升级成功,5%定位卡需要等待2个循环周期,无线升级时间均小于5 min。因此,该方法为数量较多的定位卡升级固件程序提供了一种快速、可靠和便捷的无线升级方法。

       

      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.
