A remote upgrade method and system based on nbiot network

Abstract

The present invention provides a remote upgrade method and system based on an NBIOT network, and relates to the field of the Internet of Things. The method includes: Step 10: When an NBIOT terminal device sends an upgrade request to an IOT cloud platform, obtain a difference file and a first check code , stored in the first storage area; Step 20, obtain the current program data of the NBIOT terminal equipment, store in the second storage area, update the current program data according to the difference file, and obtain the upgrade program data; Step 30, according to the The upgrade program data generates a second check code, and judges whether the second check code is consistent with the first check code. If it is inconsistent, return to step 20. If it is consistent, go to step 40; The current program data of the terminal device is replaced with the upgrade program data. The invention improves the speed of the terminal equipment program upgrade while ensuring the accuracy, and prolongs the battery life of the terminal equipment.

Description

technical field [0001] The invention relates to the technical field of the Internet of Things, in particular to a remote upgrade method and system based on an NBIOT network. Background technique [0002] With the continuous development of Internet of Things technology, the number of Internet of Things terminal devices has also continued to increase. While the functions are gradually enriched and improved, the amount of terminal program code is also increasing. How to effectively maintain and upgrade the program is a development engineer. Very tough question. For terminals with battery devices based on NBIOT network, such as smart locks based on NBIOT network, the battery life is generally required to be more than one year, while the battery life of antenna attitude detector batteries based on NBIOT network is generally required to reach to three years. [0003] The traditional program structure and upgrade method are to upgrade the entire program at the same time. However,...

[0003] The traditional program structure and upgrade method is to upgrade the whole program together. However, the data transmission rate of NBIOT narrowband IoT is low, and the whole program is upgraded together. The amount of transmitted data is large, which takes a long time and affects the service life of the battery; at the same time, the traditional The program upgrade method is to directly modify the upgrade file without effective backup and verification operations. In the NBIOT narrowband IoT data network, the network environment is often poor, which will inevitably affect the success rate of the upgrade.
