S100:Equipment total state data are read according to the preset buffer memory period, caching generates the first buffer memory device total state number
According to.
The caching period for reading equipment total state data is preset, equipment total state is read according to preset caching period
Data generate the first buffer memory device total state data according to the equipment total state data of reading.Caching period refer to it is adjacent twice
Obtain the time interval of equipment total state data.
For example, preset caching period is T, it is assumed that the first secondary device total state data are obtained in time t moment, that
The second secondary device total state data will be obtained at the t+T moment, and so on obtain the full shape of n-th equipment at t+ (N-1) the T moment
The equipment total state data buffer storage read is generated the first buffer memory device total state data by state data.So by this step
