The elevator control system comprises an NB-IOT module, a USIM module, an encoding module, an elevator control moduleand a power supply module, an NB-IOT control circuit is added under the circuit control of an original elevator; the NB-IoT module adopts a Boudica120 chip, and the Boudica120 chip is connected with the NB-IoT module. The chip integrates a baseband chip, a radio frequency chip, a power supply management unit, an application processor and a memory, rich peripheral interfaces are supported; uSIM interface and the like, the USIM module is used for door lock registration and connection with an NB-IoT network. The intelligent door lock is connected with the NB-IOT chip through an ISO7816 interfacesignal, a nano-SIM connector is adopted in order to reduce the area, and the intelligent door lock is combined with an NBIoT intelligent door lock and an intelligent cloud management platform, so thata foreground does not need to carry out card making and issuing; in the aspect of security, the NB-IoT sensing layer node can directly perform data communication with a base station in a cell to be directly connected with a cellular network, so that the potential routing security problem in the networking process is avoided.
