Embodiment 2
[0064] The second embodiment of the present invention proposes an implementation case of a data synchronization method, such as image 3 shown, including:
[0065] S301. Detect the current request parameters, wherein the request parameters include the target device and the request time interval; in this example, as Figure 4 As shown, the request parameter format of system A is {[device a, device b, device c, device d...], [T1, T2]}. Before system A initiates a request, it will first judge the validity of the parameters and process them, and save the parameters in the database table table in the format of {device i, time interval} before the request.
[0066] S302. Eliminate the request parameters duplicated with the historical request records among the current request parameters, and obtain the target request parameters;
[0067] S303. Initiate a data request to the target device by using the target request parameter;
[0068] S304. Receive the associated data sent by the ...
