Embodiment 1

[0047] see image 3 , the embodiment of the present invention provides a communication method, the execution subject of the method is a terminal, and the method includes the following steps:

[0048] S101. The terminal sends a network access request to the server;

[0049] S102. Receive channel parameters and time parameters delivered by the server, wherein the server presets multiple channels for terminals to upload data, each channel can be assigned to multiple terminals, and each channel corresponds to a channel parameter;

[0050] S103. Select a fixed channel for sending data based on the channel parameter, and send data based on the data sending time determined by the time parameter so as to stagger the data sending time of other terminals that have been allocated to the same channel.

[0051] Among them, the channel parameter specifies the channel used by the terminal to send (uplink) data, and the terminal can only send data on this channel, such as figure 2 Among th...

Embodiment 2

[0063] refer to Figure 4 , the embodiment of the present invention also provides another communication method, the execution subject is a server, and the method includes:

[0064] S201. The server receives the network access request sent by the terminal;

[0065] S202. Determine the channel parameters of the terminal, so as to select a fixed channel from a plurality of preset channels and assign it to the terminal, wherein, the server presets a plurality of channels for the terminal to upload data, and each channel can be assigned to Multiple terminals, each channel corresponding to a channel parameter; and determining the time parameter of the terminal, so that the data transmission time of the terminal is staggered from the data transmission time of other terminals that have been allocated to the same channel; regarding the channel parameters and time parameters, Reference may be made to the first embodiment above, and details are not repeated here.

[0066] S203. Send th...

Embodiment 3

[0071] An embodiment of the present invention also provides a terminal, including a processor and a memory, where the memory stores a computer program, and the computer program can be loaded by the processor to execute the method in Embodiment 1.

Abstract

The invention discloses a communication method, a terminal, a server and a computer storage medium. The method comprises the steps: enabling the terminal to send a network access request to the server; receiving channel parameters and time parameters issued by the server; selecting a fixed channel for sending data based on the channel parameter, and sending the data based on the data sending timedetermined by the time parameter so as to be staggered with the data sending time of other terminals allocated to the same channel. According to the invention, the data transmission of the terminal ismanaged from two dimensions of time and channel, so the transmission process is more efficient, it is guaranteed that no conflict exists between time and a channel when the terminal sends data, and the packet loss rate is reduced; furthermore, the server periodically issues the broadcast heartbeat packet: on the one hand, the terminal can conveniently judge whether the terminal is off line or not; on the other hand, the data sending time of the terminal can be periodically calibrated.

Description

technical field [0001] The present invention relates to the communication field, in particular to a communication method, a terminal, a server and a computer storage medium. Background technique [0002] LoRa is a wireless transmission technology. In LoRa communication, devices are divided into terminals, gateways and servers. LoRa is used for communication between the terminal and the gateway, and Ethernet is used for communication between the gateway and the server. [0003] When multiple terminals send data on the same channel at the same time, conflicts will occur, which will cause the server to be unable to receive data sent by all terminals at the same time. Since the terminal and the gateway are in half-duplex communication, it means that the terminal and the gateway cannot receive data when sending data, and cannot send data when receiving data. The time when the terminal sends and receives data is random. When the gateway sends data, if the terminal is also sendi...
