NUT(Network Update Time)、RPI(Requested Packet
Interval)這兩個(gè)參數(shù)在網(wǎng)絡(luò)中常常影響到網(wǎng)絡(luò)的帶寬,使得網(wǎng)絡(luò)不暢通或效率不高。在理論上來說當(dāng)帶寬在60%~70%網(wǎng)絡(luò)效率較高,當(dāng)帶寬不夠時(shí)就應(yīng)該減少NUT與RPI時(shí)間。另外NUT,RPI之間按一定的關(guān)系來確定數(shù)值,也能提高網(wǎng)絡(luò)效率減少帶寬,即RPI=2nNUT。
3.安裝
除了軟件設(shè)置,安裝不合格同樣會(huì)引起很多問題。
敷設(shè)ControlNet網(wǎng)絡(luò)的RG6電纜保護(hù)要做好。電纜破損,分支器進(jìn)水以及BNC頭做得不好都將影響網(wǎng)絡(luò)的暢通。在網(wǎng)線敷設(shè)好后,分支器不聯(lián)入節(jié)點(diǎn),裝上終端電阻,測量分支器聯(lián)入節(jié)點(diǎn)的BNC芯線與外層電阻應(yīng)在37.5 ~43Ω之間,小于37.5則有短路現(xiàn)象,過大則接觸不好。BNC頭的制作建議使用1786-CTK工具制作,在工具箱內(nèi)光盤中有制作的全過程的影像文件。
