Program upgrading method for NB-IOT equipment, server and NB-IOT equipment

Abstract

The embodiment of the invention discloses a program upgrading method for NB-IOT equipment, a server and the NB-IOT equipment. The program upgrading method for the NB-IOT equipment comprises the stepsthat: the NB-IOT equipment sends current software version information to the server, and receives upgrading instruction sent by the server; the NB-IOT equipment determines whether program upgrading iscarried out or not according to the attribute information of an upgrading file in the upgrading instruction and the hardware state itself; if the fact that program upgrading is carried out is determined, a upgrading request is sent to the server; and furthermore, the upgrading file sent by the server is received. Thereby, because the NB-IOT equipment can determine whether program upgrading is carried out or not according to the attribute information of the received upgrading file and the hardware state itself together, the upgrading failure problem due to the fact that the server cannot obtain the hardware state of the NB-IOT equipment and actively perform program upgrading of the NB-IOT equipment can be avoided; and thus, the program upgrading efficiency is effectively increased.

Description

technical field [0001] The present invention relates to the field of Internet of Things data processing, in particular to a method for upgrading programs of NB-IOT devices, a server and NB-IOT devices. Background technique [0002] Narrow Band Internet of Things (NB-IOT) technology is a new type of Internet of Things technology proposed by the Global Third Generation Partnership Project (3GPP), and it is an important branch of the Internet of Everything. It is built on the cellular network and supports the data connection of low-power devices in the wide area network. It has the characteristics of large capacity, wide coverage, low power consumption, low cost, and high stability. In recent years, NB-IOT technology has developed rapidly, and its many applications (such as smart water meters, smart meters, parking lot management, etc.) have gradually entered people's lives. [0003] In the prior art, the NB-IOT device can work normally after installing the corresponding progr...

AI Technical Summary

Problems solved by technology

Under normal circumstances, the hardware configuration of NB-IOT devices is generally relatively low, and the support for large storage space and large memory space is relatively low, and the data volume of the upgrade file required to upgrade the program in the NB-IOT device is relatively large. Big

Therefore, since the server cannot know the device status of the NB-IOT device, the upgrade file sent by the server may not be completely received due to insufficient storage space or memory space, or it may not be installed normally even if it is completely received, thus giving customers The terminal brings a lot of burden, resulting in a relatively low efficiency of program upgrades
