Problems solved by technology

The LoRa terminal 100 is either manually upgraded through a serial port or USB, which is time-consuming and laborious; or there is no interface, and once the LoRa terminal 100 needs to be upgraded due to product problems, it will be recalled in large quantities, and the cost is huge; or it can be upgraded wirelessly through LoRa, but for It does not affect the normal operation of the LoRa terminal 100 that has not been upgraded. It is necessary to switch the LoRa frequency of the LoRa terminal 100 to an idle frequency point (dedicated upgrade frequency) before upgrading. The upgrade process is complicated and a dedicated frequency point needs to be reserved

Embodiment Construction

[0031] The technical problem to be solved by the present invention is: the LoRa terminal 100 is either manually upgraded through a serial port or USB, which is time-consuming and laborious; or there is no interface, once the LoRa terminal 100 needs to be upgraded due to product problems, it will be recalled in large quantities, and the cost is huge; Either through the wireless upgrade of LoRa, but in order not to affect the normal operation of the unupgraded LoRa terminal 100, it is necessary to switch the LoRa frequency of the LoRa terminal 100 to an idle frequency point (dedicated upgrade frequency) before upgrading. The upgrade process is complicated and requires Reserve dedicated frequency points. The idea proposed by the present invention with respect to this technical problem is: construct a LoRa-based air upgrade method and system, combine unicast and broadcast to upgrade the LoRa terminal 100, and realize simultaneous multi-LoRa terminal according to the mode of allocat...

Abstract

The invention provides an air upgrading method and system based on LoRa. The over-the-air upgrading method comprises the following steps: a LoRa gateway allocates a corresponding time slot and a corresponding frequency point to each LoRa terminal in a plurality of LoRa terminals; the LoRa terminal uplink the serial number of the requested firmware and the number of the received fragment data packets at the corresponding time slot and frequency point; the FOTA server receives the serial number of firmware requested by the LoRa terminal and the number of received fragment data packets through the LoRa gateway; the FOTA server counts all serial numbers of the firmware received by the FOTA server within a preset time period, and then sends fragment data packets, corresponding to the serial numbers, of the firmware to the LoRa gateway; and the LoRa gateway sends the fragment data packets of the firmware to the corresponding LoRa terminals one by one at the allocated time slots and frequency points in a broadcast mode. The air upgrading method and system are novel in design and high in practicability.

Description

technical field [0001] The invention relates to the field of data transmission, in particular to a LoRa-based air upgrade method and system. Background technique [0002] At present, IoT networking solutions based on LoRa communication are widely used. The LoRa terminal 100 is either manually upgraded through a serial port or USB, which is time-consuming and laborious; or there is no interface, and once the LoRa terminal 100 needs to be upgraded due to product problems, it will be recalled in large quantities, and the cost is huge; or it can be upgraded wirelessly through LoRa, but for Without affecting the normal operation of the unupgraded LoRa terminal 100, it is necessary to switch the LoRa frequency of the LoRa terminal 100 to an idle frequency point (dedicated upgrade frequency) before upgrading, the upgrade process is complicated, and a dedicated frequency point needs to be reserved. Contents of the invention [0003] Aiming at the above-mentioned technical problem...
