| GPRS在動車組車載故障信息無線傳輸過程的應(yīng)用(20 卷) |
| 英文標題 |
| Application of GPRS in on-board fault information radio transmission of EMU |
| 摘要 |
| 本文介紹了動車組故障診斷系統(tǒng)中，車載實時數(shù)據(jù)和故障報文通過GPRS傳輸?shù)降孛娣?wù)器的具體實現(xiàn)過程。GPRS模塊采用了西門子MC55模塊。GPRS模塊通過向串口中發(fā)送AT指令，實現(xiàn)向地面服務(wù)器傳輸車載實時報文，為地面管理人員及時了解動車組運行狀況并進行故障處理提供方便。 |
