A method and device for unlocking access control based on narrowband internet of things

Abstract

The embodiment of the present application discloses an access control unlocking method and device based on NB-IoT. The technical solution provided by the embodiment of the present application provides access control QR codes that change over time through wireless access control. The user terminal scans the access control QR code to obtain the target access control information and sends an access control unlock request. After receiving the access control unlock request from the user terminal According to the target access control information and user information carried in the access control unlock request, the access control verification is performed and the corresponding access control verification result is returned to the NB-IoT gateway. The access control QR code that changes over time can reduce the situation that users who take photos and record the access control QR code to remotely unlock the wireless access control, which causes users who do not carry user terminals to pass through the wireless access control, effectively ensuring the security of the wireless access control.

Description

technical field [0001] The embodiments of the present application relate to the technical field of the narrowband Internet of Things, and in particular, to an access control unlocking method and device based on the narrowband Internet of Things. Background technique [0002] With the accelerated pace of social life, more and more people will choose to rent houses in cities where they work. In order to ensure the safety of people's living environment, wireless access control is usually set up at the entrance and exit of houses. [0003] At present, the communication technology of wireless access control system usually adopts cellular communication technology such as GSM, CDMA, WCDMA, etc., the use of the above communication technology has the problem of weak signal coverage, and the communication is often poor and cannot be implemented in complex environments. The emergence of NB-IoT technology solves the problem of signal coverage for access control unlocking in complex envi...

Problems solved by technology

[0003] At present, the communication technology of the wireless access control system usually adopts cellular communication technologies such as GSM, CDMA, and WCDMA. Using the above-mentioned communication technologies has the problem of weak signal coverage, and in complex environments, communication often occurs and cannot be implemented.

The emergence of NB-IoT technology has solved the signal coverage problem of access control unlocking in complex environments. However, for the method of requesting unlocking access control by scanning the QR code of the access control, there is a problem that the user carrying the user terminal can remotely unlock the wireless access control through the QR code of the access control that is recorded by taking pictures. Access control, causing users who do not carry user terminals to pass through wireless access control, posing a threat to the security of wireless access control
