Fecha de publicación: 04/12/2020 Fuente: Wipo "IOT" The invention relates to an NB-IoT gateway which comprises a single-chip microcomputer used for being connected with a data port of a first external device, an NB-IoT module used for being connected with a server and a microprocessor used for being connected with a data port of a second external device. The NB-IoT module, the single-chip microcomputer and the microprocessor are connected in sequence. The dual processors, namely the single-chip microcomputer and the microprocessor, are connected with data ports of different external devices so as to receive and process data returned by the different external devices, so that the information processing efficiency is guaranteed. Moreover, the NBIoT module based on the NBIoT can ensure that data returned by different external devices can be transmitted to the server for storage or secondary processing, and the NBIoT module based on the NBIoT can be connected with the data ports of tens of thousands of external devices, and does not occupy4G resources of passengers. Therefore, the NBIoT gateway provided by the invention can also ensure the data storage efficiency and the data processing efficiency under the conditions that the airportpedestrian flow information is increasingly increased and the monitoring management requirement is increasingly increased.
