Fuente: Wipo "IOT" The utility model discloses a private network architecture based on NB-IOT industrial Internet of Things. The whole network adopts an NB-IOT private network; the system comprises an NB-IOT Internet ofThings gateway, an NB-IOT private network cloud server and an NB-IOT wireless private network management machine, wherein the NB-IOT Internet of Things gateway is responsible for collecting equipmentinformation of an industrial field; the information is sent to the NB-IOT private network cloud server through the NB-IOT private network; the NB-IOT private network cloud server forwards the data ofthe NB-IOT Internet of Things gateway to the NB-IOT wireless private network management machine, the NB-IOT wireless private network management machine is provided with an RJ45 interface and an RS485interface, and a user can read the data of field equipment through the RJ45 interface or the RS485 interface. The industrial Internet of Things private network is realized by adopting NB-IOT, so thatthe construction cost and the construction difficulty are greatly reduced, and meanwhile, the information security and the data security are correspondingly guaranteed.
