The embodiment of the invention provides a short-distance communication method based on an NB-LOT network, which can be applied to a terminal, a server, software running in the terminal or the server, such as an application program with an image color constancy processing function and the like. The terminal may be, but is not limited to, a smart phone, a tablet computer, a laptop computer, a desktop computer, a smart speaker, a smart watch, and the like. The server may be an independent physical server, a server cluster or a distributed system formed by a plurality of physical servers, or a cloud server providing basic cloud computing services such as cloud service, a cloud database, cloud computing, a cloud function, cloud storage, network service, cloud communication, middleware service, domain name service, security service, CDN, and a big data and artificial intelligence platform. Referring to fig. 1, the method includes the following steps S100 to S400:

And S102, networking the terminal equipment according to the equipment list.
It is particularly desirable that the first terminal device and the second terminal device are selected from a list of devices.
S200, reading the signal intensity of the terminal equipment in the NB-IoT network, and establishing a signal intensity list;
s300, transmitting data through the first terminal equipment by utilizing an NB-IoT network and selecting the second terminal equipment as a relay route when the data transmission fails; the second terminal equipment is the terminal equipment with the optimal signal intensity except the first terminal equipment in the signal intensity list; in an actual application scenario, after the first terminal device fails to transmit, a second terminal device available for data interaction is queried through the signal strength list, and the selection of the second terminal device is determined according to the signal strength of the terminal device in the signal strength list in the NB-IoT network.
S400, forwarding data to be sent by the first terminal equipment through the second terminal equipment; in an actual application scenario, the second terminal device fulfills the function of the relay route, the first terminal device cannot send data to the outside through a normal network path, so that the data to be sent is forwarded to the second terminal device through a short-distance communication mode after networking, and the second terminal device sends the data to the outside through the normal network path.
Alternatively, S400 may be implemented by:
s401, sending data to be sent to a second terminal device through a first terminal device;
