In an optional embodiment, the detecting, by the first terminal, whether a link between the first terminal and the at least one second terminal is failed includes: the first terminal detects whether the first terminal has a fault; a first terminal detects that a network environment where a network link is located has a fault;
through the steps, the purpose that whether the network link between the first terminal and the at least one second terminal is in failure or not can be achieved.
Step S104, when the first terminal detects a fault, the first terminal sends a first broadcast message to at least one second terminal, wherein the first broadcast message carries synchronous information;
in step S104, the synchronization information refers to synchronization information between the configuration information of the first terminal and the configuration information of the second terminal, and specifically, when the configuration information is changed, the first terminal synchronizes the changed configuration information to at least one second terminal;

Optionally, the first broadcast message is a message obtained by encapsulating the synchronization information by using a UDP protocol; the network link is a link using transmission control protocol TCP. That is, the synchronization information may be broadcast using UDP.
Optionally, the first terminal is a master terminal, and the second terminal is a slave terminal; when the first terminal fails, the master terminal may be determined by, but is not limited to: a designated terminal in the at least one second terminal receives the setting instruction; setting the designated terminal as a main terminal according to the setting instruction; or, at least one second terminal negotiates, and a main terminal is determined from the at least one second terminal according to a preset rule;

step S204, when the main terminal is in fault, the merchant sets other terminals on the terminal as the main terminal, wherein after the setting is finished, the main terminal sends a broadcast notice to inform that the main terminal in the local area network is changed, and simultaneously, a cloud interface is called to modify the setting of the cloud main terminal;
step S206, the slave terminal receives the information and then modifies the configuration information of the local master terminal, wherein, after the setting is finished, the data updating is carried out on the master terminal equipment, and after the updating, the master terminal sends a broadcast to inform that the master terminal in the local area network is changed; modifying the local main terminal configuration information after receiving the information from the terminal;
step S208, after the main terminal network is abnormally reconnected, the cloud synchronously acquires the latest main terminal configuration information and compares the latest main terminal configuration information with the local configuration information, wherein the configuration information of the local main terminal is modified when the two are inconsistent;
step S210, when all terminal devices are started, cloud main terminal configuration information needs to be synchronized and local information needs to be returned to a cloud, wherein when the cloud main terminal is set to be changed, whether synchronization is successful needs to be judged through a change mark;
through the steps S202 to S210, a manner that the first terminal detects whether a network link between the first terminal and the at least one second terminal has a fault is adopted, and when the first terminal detects the fault, the first terminal sends the first broadcast message to the at least one second terminal.
