描述
采用“滑動(dòng)窗口”機(jī)制。DI模塊中開(kāi)設(shè)固定數(shù)據(jù)存儲(chǔ)區(qū)的“滑動(dòng)窗口”,固定上報(bào)最近4個(gè)采樣周期的DI數(shù)據(jù),這樣可以將每個(gè)采樣周期的數(shù)據(jù)在DI模塊中保持4個(gè)采樣周期。此時(shí)以50 ms分辨率周期采集數(shù)據(jù),每個(gè)采樣周期的數(shù)據(jù)最多可以在DI模塊中保留200 ms,這樣DI從站有足夠的時(shí)間將采集的數(shù)據(jù)傳送給DP主站,保證DI數(shù)據(jù)無(wú)丟失。相比較而言,第2種方案對(duì)系統(tǒng)的影響小,可行性高。KIT/KPS項(xiàng)目改進(jìn)實(shí)施
