摘要： 在軌道交通控制系統(tǒng)中，為了保證車輛控制穩(wěn)定和運(yùn)行數(shù)據(jù)及故障記錄準(zhǔn)確可靠，其關(guān)鍵部件——中央控制單元（Central Control Unit， CCU）和數(shù)據(jù)記錄單元（Event Record Machine， ERM）采用嵌入式實(shí)時(shí)操作系統(tǒng)VxWorks。一般情況下，該系統(tǒng)啟動(dòng)時(shí)需要先啟動(dòng)DOS，之后再被當(dāng)作一般軟件調(diào)用啟動(dòng)。在系統(tǒng)啟動(dòng)失敗、前面板6個(gè)燈常亮故障的基礎(chǔ)上，研究DOS對(duì)電子盤的讀寫對(duì)其啟動(dòng)過(guò)程的影響，提出并驗(yàn)證一種可以直接在FAT32格式電子盤上啟動(dòng)解決方案，避免系統(tǒng)啟動(dòng)失敗問(wèn)題。然后結(jié)合作者遇到的不同版本VxWorks在應(yīng)用過(guò)程中的UDP單播問(wèn)題、FTP文件傳輸問(wèn)題、啟動(dòng)檢查DBR及讀寫LBA扇區(qū)問(wèn)題進(jìn)行測(cè)試，并提出了解決方案。

Abstract： In the network communication control system of rail transit, in order to ensure the stability of vehicle control and the accuracy and reliability of operation data and fault records, the central control unit (CCU) and event record machine (ERM), the key components, adopt an embedded real-time operating system VxWorks. Generally, when the system starts, it needs to start the DOS first, and then it is started as a general software call. In this paper, based on the system startup failure and the failure of 6 lights on the front panel, it studies the influence of DOS reading and writing to the electronic disk on its startup process, and proposes and validates a solution that can directly start on the FAT32 format electronic disk to avoid the problem of system startup failure. Then, according to the problems of UDP unicast, FTP file transfer, DBR startup check and LBA sector read and write in different versions of VxWorks encountered by the author, the solutions are put forward.

引言
自從某款中央控制單元(Central Control Unit,CCU)和數(shù)據(jù)記錄單元(Event Record Machine，ERM)設(shè)備應(yīng)用到各項(xiàng)目之后，陸續(xù)收到多起客服人員反饋關(guān)于該CCU和ERM上電啟動(dòng)時(shí)全部6個(gè)燈常亮、VxWorks操作系統(tǒng)不啟動(dòng)的問(wèn)題。作者在調(diào)試過(guò)程中也遇到不同VxWorks版本的若干問(wèn)題，都將在本文中討論。
