Embodiment 1
[0024] The structure diagram of the NB-IOT meter firmware upgrade system of the present invention is as follows figure 1 As shown, the present invention is realized by using BLE (Bluetooth Low Energy, Bluetooth Low Energy) technology. The system includes an OTA platform, a mobile user terminal and at least one NB meter terminal;
[0025] The NB meter terminal has a near-field communication function; the mobile client is installed with meter reading software, and performs BLE near-field communication with the NB meter terminal through the meter reading software, and communicates with the OTA platform through a mobile network (4G / 5G network) ; When the mobile network between the OTA platform and the NB meter terminal is blocked, the OTA platform sends the firmware upgrade package to the mobile client through the mobile network, and the mobile client sends the firmware upgrade package to the mobile client through BLE near field communication. NB meter terminal.

The invention discloses an NB-IOT meter firmware upgrading system and upgrading method. The upgrading system comprises an OTA platform, a mobile user side and at least one NB meter terminal. The NB meter terminal comprises a BLE data transmission module; meter reading software is installed on the mobile user side, BLE near-field communication is carried out between the mobile user side and the NBmeter terminal through the meter reading software, and the mobile user side communicates with the OTA platform through a mobile network. And the OTA platform sends the firmware upgrade package to themobile user side through the mobile network, and the mobile user side sends the firmware upgrade package to the NB meter terminal through BLE near field communication. Via the system disclosed in theinvention, the problem that the firmware cannot be upgraded when the NB meter terminal has no 4G or 5G network signal is solved, and the reissuing or issuing of the firmware upgrade package can be completely completed. By utilizing the characteristics of the BLE large flash, the issued firmware upgrade package is stored in the flash of the BLE near-end communication module, and the hardware cost is not increased.
Description
technical field [0001] The invention relates to the technical field of meters such as water meters and gas meters, and in particular to an NB-IOT meter firmware upgrade system and an upgrade method. Background technique [0002] In recent years, as NB-IOT (Narrow Band Internet of Things, narrowband Internet of Things) smart water and gas meters have been installed and used in large quantities in water meter companies and gas meter companies, the firmware upgrade of battery-powered NB-IOT water and gas meters will be a challenge. The current NB-IOT wireless upgrade generally adopts the upgrade method of sending FOTA (FirmwareOver-The-Air, wireless firmware upgrade) differential packets through the NB wireless channel. This upgrade method is relatively stable for the network, and the firmware changes are small. Energy-consuming NB IoT terminals are more effective. This upgrade method requires twice as much flash (flash memory) as a cache to store OTA (Over-The-Air, air downl...
