NB-IOT-based intelligent terminal equipment and module remote upgrading method

The invention discloses an NB-IOT-based intelligent terminal equipment and module remote upgrading method. The method adopts two communication paths, wherein the path 1 consists of terminal equipment,an NB network, an operator internet of things platform, and an application server, and serves as a CoAP path, the terminal equipment reaches the operator internet of things platform through the NB network and then reaches the application server so as to communicate, the path 2 consists of terminal equipment, an NB network and an application server, the terminal equipment directly uses a UDP protocol to communicate with the application server, the path 2 servers as a UDP path, when terminal equipment data is reported, an application server command is delivered, and a wireless NB-IoT module firmware is upgraded, the path 1 is used alone, when an MCU firmware is upgraded, both the paths 1 and 2 are used. COAP and UDP protocol solutions are combined organically, so that a problem that terminal equipment is upgraded r
