PAGEPAGE1VMS-前臺接口方案VMS系統(tǒng)與前臺PMS系統(tǒng)用RS232串行通信進(jìn)行連接開房：酒店客人入住時，PMS系統(tǒng)向VMS系統(tǒng)發(fā)開房指令，VMS系統(tǒng)收到開房指令后，自動建立相應(yīng)的客房留言信箱。退房：酒店客人退房時，PMS系統(tǒng)向VMS系統(tǒng)發(fā)退房指令，VMS系統(tǒng)收到退房指令后，自動關(guān)閉相應(yīng)的客房留言信箱。串行口參數(shù)設(shè)置串口波特率:9600b/s(默認(rèn))數(shù)據(jù)位:8奇偶校驗位:無停止位:1流控:無同步方式:異步通信命令物理層采用RS232簡單連接方法，3根連線，分別為接收，發(fā)送和地。邏輯層控制字節(jié)：<STX>(Hex02)標(biāo)識一個數(shù)據(jù)紀(jì)錄的開始。<ETX>(Hex03)標(biāo)識一個數(shù)據(jù)紀(jì)錄的結(jié)束，但不是數(shù)據(jù)的組成部分。<ENQ>(Hex05)當(dāng)發(fā)送方發(fā)出信息后，沒有得到對方會應(yīng)，用作請求一個邏輯層的回應(yīng)。正常情況下，發(fā)送方在發(fā)送一個數(shù)據(jù)紀(jì)錄后2秒之內(nèi)收到回應(yīng)，如果超時或收到的包不是<STX>，<ACK>或<NAK>，則發(fā)出<ENQ>，最多發(fā)三次，如果得不到回應(yīng)，則表示丟棄紀(jì)錄，并記下這個錯誤到LOG文件。<ENQ>的標(biāo)準(zhǔn)回應(yīng)是<ACK>和<NAK>，如果收到<ACK>回應(yīng)，代表對方已經(jīng)正確接受信息，如果收到<ACK>回應(yīng)，發(fā)送方重發(fā)最后一條紀(jì)錄。<ACK>接受方表示正確接受一個校驗正確的紀(jì)錄，但并不表示紀(jì)錄的內(nèi)容是可以接受的。<NAK>接受方表示發(fā)現(xiàn)最后一個紀(jì)錄檢驗錯誤，請求重發(fā)。重發(fā)請求不超過4次，超出則在發(fā)送和接受方在LOG文件紀(jì)錄，并丟棄這條紀(jì)錄。 附：開房、退房指令的格式：Checkin(Host=>VMS)12345671234567890123456789012345678901234567890123456789012345678901234567890IYYMMDDHHMMSSRRRRRXXXXXXXXXXXXXXXXXXXXXXXXXXXXXVVLLGGI060229102300404ZouJianLiangMr00C01Whereby:I:Indicatorformessage(I)YYMMDD:TransactionDateHHMMSS:TransactionTimeRRRRR:Roomnumber(leftjustify)X(30):GuestName(leftjustify)VV:Telephoneclassofservice(leftjustify)LL:LanguageCode(leftjustify)GG:Groupnumber(leftjustify)ChangeofGuestInformation(Host=>VMS)12345671234567890123456789012345678901234567890123456789012345678901234567890GYYMMDDHHMMSSRRRRRXXXXXXXXXXXXXXXXXXXXXXXXXXXXXVVLLGGG060229102300404ZouJianLiangMr00C01Whereby:G:Indicatorformessage(G)YYMMDD:TransactionDateHHMMSS:TransactionTimeRRRRR:Roomnumber(leftjustify)X(30):GuestName(leftjustify)VV:Telephoneclassofservice(leftjustify)LL:LanguageCode(leftjustify)GG:Groupnumber(leftjustify)CheckOut(Host=>VMS)12345671234567890123456789012345678901234567890123456789012345678901234567890OYYMMDDHHMMSSRRRRRO020729142300508Whereby:O:Indicatorformessage(O)YYMMDD:TransactionDateHHMMSS:TransactionTimeRRRRR:Roomnumber(leftjustify)TEXTMessageWaiting12345671234567890123456789012345678901234567890123456789012345678901234567890NYYMMDDHHMMSSRRRRRWhereby:N:Indicatorformessage(N)YYMMDD:TransactionDateHHMMSS:TransactionTimeRRRRR:Roomnumber(leftjustify)TEXTMessageWaitingOFF(Host=>VMS)12345671234567890123456789012345678901234567890123456789012345678901234567890FYYMMDDHHMMSSRRRRRWhereby:F:Indicatorformessage(F)YYMMDD:TransactionDateHHMMSS:TransactionTimeRRRRR:Roomnumber(leftjustify)SETDND(Host=>VMS)12345671234567890123456789012345678901234567890123456789012345678901234567890AYYMMDDHHMMSSRRRRRWhereby:A:Indicatorformessage(A)YYMMDD:TransactionDateHHMMSS:TransactionTimeRRRRR:Roomnumber(leftjustify)CANCELDND(Host=>VMS)12345671234567890123456789012345678901234567890123456789012345678901234567890ZYYMMDDHHMMSSRRRRRWhereby:Z:Indicatorformessage(Z)YYMMDD:TransactionDateHHMMSS:TransactionTimeRRRRR:Roomnumber(leftjustify)VoiceMessage(VMS=>HOST)12345671234567890123456789012345678901234567890123456789012345678901234567890PYYMMDDHHMMSSRRRRRUUFFWhereby:p:Indicatorformessage(P)YYMMDD:TransactionDateHHMMSS:TransactionTimeRRRRR:RoomnumberUU:NumberofUnreadVoiceMessagesFF:NumberofReadVoiceMessagesSetWakeupCall12345671234567890123456789012345678901234567890123456789012345678901234567890WYYMMDDHHMMSSRRRRRTTTTWhereby:W:Indicatorformessage(W)YYMMDD:TransactionDateHHMMSS:TransactionTimeRRRRR:RoomnumberTTTT:WakeupTimeCancelWakeupCall12345671234567890123456789012345678901234567890123456789012345678901234567890XYYMMDDHHMMSSRRRRRWhereby:X:Indicatorformessage(X)YYMMDD:TransactionDateHHMMSS:TransactionTimeRRRRR:RoomnumberTTTT:WakeupTimeMiniBarCharges(VMS=>HOST)12345671234567890123456789012345678901234567890123456789012345678901234567890MYYMMDDHHMMSSRRRRRITQSSSSM05113012034610001220003M05113012034610001310003Whereby:M:Indicatorformessage(M)YYMMDD:TransactionDateHHMMSS:TransactionTimeRRRRR:RoomnumberIT:ITEMQ:QtySSSS:SerialNumberRoomStatus(VMS=>HOST)12345671234567890123456789012345678901234567890123456789012345678901234567890RYYMMDDHHMMSSRRRRRXWhereby:R:Indicatorformessage(R)YYMMDD:TransactionDateHHMMSS:TransactionTimeRRRRR:RoomnumberX:1-VC;2-VD
