The technical scheme is summarized as follows: a control terminal is used for judging whether the NB-IOT equipment needs to be upgraded or not under user operation or automatic detection; through an application server and an NB-IOT platform, an upgrading instruction is sent to the NB-IOT equipment needing to be upgraded; according to the upgrading instruction, the corresponding NB-IOT equipment calls a built-in wireless communication module to download data for carrying out upgrading; and after the upgrading is completed, an upgrading result is fed back to the control terminal through the application server and the NB-IOT platform. The beneficial effectsare as follows: when the NB-IOT equipment is subjected to software upgrading, the software data is downloaded in a communication mode that the bandwidth is greater than that of an NB-IOT network, suchas WIFI or the like; and due to the fact that the network bandwidth is large, the required data can be downloaded in a few seconds, so that a lot of time is saved, and the software upgrading efficiency of the NB-IOT equipment is improved. The software upgrading system and method is particularly suitable for the NB-IOT positioning equipment based on a WIFI probe.
