PCF8562是一種能與幾乎所有低復(fù)用速率的LCD接口的外圍設(shè)備。它為所有靜態(tài)和復(fù)合的LCD（包含最多4個(gè)背極和32段）產(chǎn)生驅(qū)動(dòng)信號(hào)。PCF8562與大多數(shù)微處理器／微控制器兼容并可以通過兩線雙向的I2C總線通信。通過帶自動(dòng)增量尋址的顯示RAM、硬件子地址尋址和顯示存儲(chǔ)器切換（靜態(tài)和復(fù)合驅(qū)動(dòng)模式）可以將通信的開銷降至最低。

摘要:礦用隔爆型低壓饋電開關(guān)是煤礦配電系統(tǒng)的關(guān)鍵環(huán)節(jié),其好壞直接影響著煤礦井下生產(chǎn)安全和生產(chǎn)效率。而低壓饋電開關(guān)的智能化程度主要取決于保護(hù)系統(tǒng)的可靠性和靈敏性。本設(shè)計(jì)研制的井下低爆綜合保護(hù)器,依據(jù)MT871-2000《礦用隔爆型低壓交流真空饋電開關(guān)》標(biāo)準(zhǔn),能對(duì)低壓電網(wǎng)中出現(xiàn)的短路、過載、過壓、欠壓、漏電等故障進(jìn)行實(shí)時(shí)檢測(cè),并有方便的兩鍵參數(shù)設(shè)定和全中文液晶顯示功能。通過對(duì)井下低壓供電不同方式的深入研究,本設(shè)計(jì)較好地解決了功率方向型漏電的誤動(dòng)作和拒動(dòng)作問題,以及短路、漏電等故障的越級(jí)跳閘的問題。關(guān)鍵詞:漏電;低壓電網(wǎng);綜合保護(hù)器;單片機(jī)
