普通計(jì)數(shù)器受CPU掃描速度的影響,是按照順序掃描的方式進(jìn)行工作。在每個(gè)掃描周期中,對(duì)計(jì)數(shù)脈沖只能進(jìn)行一次累加;對(duì)于脈沖信號(hào)的頻率比CPU的掃描頻率高時(shí),如果仍采用普通計(jì)數(shù)器進(jìn)行累加,必然會(huì)丟失很多對(duì)輸入脈沖信號(hào)。在CPU中,對(duì)比掃描頻率高的輸入信號(hào)的計(jì)數(shù)可也使用高速計(jì)數(shù)器指令來(lái)實(shí)現(xiàn)。
1.高速計(jì)數(shù)器指令
  高速計(jì)數(shù)器的指令包括:定義高數(shù)計(jì)數(shù)器指令HDEF和執(zhí)行高速計(jì)數(shù)指令HSC,如下表

(1) 定義高速計(jì)數(shù)器指令HDEF
HDEF指令功能是為某個(gè)要使用的高速計(jì)數(shù)器選定一種工作模式。每個(gè)高速計(jì)數(shù)器在使用前,都要用HDEF指令來(lái)定義工作模式,并且只能用一次。它有兩個(gè)輸入端:HSC為要使用的高速計(jì)數(shù)器編號(hào),數(shù)據(jù)類型為字節(jié)型,數(shù)據(jù)范圍為0~5的常數(shù),分別對(duì)應(yīng)HC0~ HC5;MODE為高速計(jì)數(shù)的工作模式,數(shù)據(jù)類型為字節(jié)型,數(shù)據(jù)范圍為0~11的常數(shù),分別對(duì)應(yīng)12種工作模式。當(dāng)準(zhǔn)許輸入使能EN有效時(shí),為指定的高速計(jì)數(shù)器HSC定義工作模式MODE。
(2)執(zhí)行高速計(jì)數(shù)指令HSC
 HSC指令功能功能是根據(jù)與高速計(jì)數(shù)器相關(guān)的特殊繼電器確定在控制方式和工作狀態(tài),使高速計(jì)數(shù)器的設(shè)置生效,按照指令的工作模式的工作模式執(zhí)行計(jì)數(shù)操作。它有一個(gè)數(shù)據(jù)輸入端N:N為高速計(jì)數(shù)器的編號(hào),數(shù)據(jù)類型的字型,數(shù)據(jù)范圍為0~5的常數(shù),分別對(duì)應(yīng)高速計(jì)數(shù)器HC0~HC5.當(dāng)準(zhǔn)許輸入EN使能有效時(shí),啟動(dòng)N號(hào)高速計(jì)數(shù)器工作。
2.高速計(jì)數(shù)器的輸入端
高速計(jì)數(shù)器的輸入端不像普通輸入端那樣有用戶定義,而是由系統(tǒng)指定的輸入點(diǎn)輸入信號(hào),每個(gè)高速計(jì)數(shù)器對(duì)它所支持的脈沖輸入端,方向控制,復(fù)位和啟動(dòng)都有專用的輸入點(diǎn),通過(guò)比較或中斷完成預(yù)定的操作。每個(gè)高速計(jì)數(shù)器專用的輸入點(diǎn)如
高速計(jì)數(shù)器的輸入端不像普通輸入端那樣有用戶定義,而是由系統(tǒng)指定的輸入點(diǎn)輸入信號(hào)system and the configuration software based on Web technology to centrally monitor the power data and power equipment at all points of the school, so as to facilitate the operator to monitor the power status and record the data.

2. Key points and difficulties

The key and difficult point of this system is that it needs to centrally monitor a large area of power data, and there are multiple host computers to monitor.

3. Solution

The distributed control system adopts multiple industrial Ethernet programmable controllers (PLC) as the main controller to collect the power data of multiple substation kiosks. An industrial computer is configured in the studio as a server to communicate with the on-site PLC through the campus LAN, collect data and publish it on the web. As long as other monitoring computers are connected to the campus LAN, they can monitor the power system by inputting the website published by the server in IE browser, so as to meet the multi-point remote monitoring.
