Device control method and system for NB-IOPT terminal

Abstract

The invention relates to a device control method and system for an NB-IOPT terminal. The method comprises the following steps: sending a handshake request message to a narrowband Internet of Things terminal after every first preset time; when the narrowband Internet of Things terminal does not feed back a handshake response message of the corresponding handshake request message within a second preset time, confirming handshake failure; and if the number of handshake failures is equal to a preset threshold, performing reset processing on the narrowband Internet of Things terminal, and resettingthe number of handshake failures. According to the device control method and system provided by the invention, handshake is made with the narrowband Internet of Things terminal, whether the narrowband Internet of Things terminal is in a normal working state is confirmed according to the number of handshake failures, and when the narrowband Internet of Things terminal is not in the normal workingstate, the narrowband Internet of Things terminal is reset in time to restore the work of the narrowband Internet of Things terminal, thereby shortening the delay of manually restoring the work of thenarrowband Internet of Things terminal, and the working state of the narrowband Internet of Things terminal is restored in time to ensure the transmission of the Internet of Things information.

Description

technical field [0001] The present invention relates to the technical field of the Internet of Things, in particular to a device control method and system for NB-IOT terminals. Background technique [0002] Narrowband Internet of Things (NB-IoT) is one of the many technologies of Low Power Wide Area Network (Low Power Wide Access, LPWA), which can support the cellular data connection of low power consumption devices in the Wide Area Network. NB-IoT has four major characteristics: First, wide coverage, which will provide improved indoor coverage. Under the same frequency band, NB-IoT has a gain of 20dB compared with the existing network, and the coverage area is expanded by 100 times; second, it has the ability to support massive connections. Ability, a sector of NB-IoT terminal can support 100,000 connections, support low latency sensitivity, ultra-low equipment cost, low power consumption and optimized network architecture; the third is lower power consumption, NB-IoT termi...

AI Technical Summary

Problems solved by technology

[0003] When the NB-IoT terminal crashes abnormally, the user cannot receive the IoT information in time, and may cause losses due to missing important information. In the traditional solution, when the NB-IoT terminal crashes abnormally, it needs to be manually reset, but The staff cannot restore the work of the NB-IoT terminal in the first place, which may easily affect the real-time and accuracy of relevant data
