中文摘要 | 捷運木柵線VAL 256電聯車每一車廂設置二套空調系統,分別獨立運作,由於是獨立車廂之設計,如遇到空調系統故障,因車廂間空調無法相互支援,造成車廂悶熱而影響乘車品質。經分析其原因,除一部分為空調設備零件故障需進廠維修外,另絕大部分故障為空調電路板CPU 當機造成壓縮機停止,必須予以重置;然原廠並未設計空調電路板CPU當機警訊回傳及遠端重置之功能,以致發生該故障時,行控中心無法在第一時間獲得警訊進行故障排除。本案研發空調自動切換重置電路,可在空調電路板當機後自動重置,除可解決因空調電路板當機造成車廂悶熱及旅客不適外,亦可減少人工重置空調電路板所需之工時。 |
英文摘要 | Each cabinet of VAL 256 vehicle of Mucha line was installed 2 sets of air conditioning system which are controlled by an individual A/C board espectively. Due to isolated cabinet design for the vehicle, air conditioner in one cabinet can not support to another while A/C failure occurs. The failure also causes stuffy cabinet and influence the ride quality. One reason to cause A/C fault is parts breakdown, but major reason is of A/C board's CPU crashing and leading to shut down A/C compressor. Operation control center (OCC) could not be able to gain the alarm and to reset A/C board in the nick of time because CPU crash alarm and remote reset functions were not designed in the VAL 256 vehicle. Aim at this defect, this project is to develop a watching dog circuit to reset A/C board's CPU automatically when the CPU crashed. Not only does it solve the problem as stuffy cabinet and passenger's complaint caused by A/C board' s CPU crashed, but it also reduces technician's work-hours to manually reset it. |
