Fecha de publicación: 14/07/2020 Fuente: Wipo "IOT" The utility model discloses an NB-IOT module power supply system. The NB-IOT module power supply system comprises a magnetic coil device, a super capacitor and a switch device. When the magnetic coildevice generates a potential difference, the potential difference charges the super capacitor through the switch device, and the charged super capacitor supplies power to the NB-IOT module through theswitch device. According to the NB-IOT module power supply system provided by the utility model, when the NB-IOT module needs to be used for working, the NB-IOT module can be used for supplying power; the magnetic coil device is used for generating the potential difference to charge the super capacitor, and then the super capacitor is used for supplying power to the NB-IOT module, so that normaluse of the NB-IOT module can be conveniently realized without additionally using a battery or a power supply, and energy is saved.
