  1. 專題進度報告 分房管理系統- (11) 進度:1.Reader PCB Layout 與實測 2.Layout修正 學生:向崇羽 指導老師:陳銘志老師 陳建興老師

  2. ◎LED燈號架構 問題1:閒置時訊號為1,使得LED燈恆亮 解決1:改成反相(下圖) 問題2:XBEE_IN、XBB_OUT 訊號被吃掉(導通短路) 解決2:接上RB10K電阻

  3. ◎PCBLayout –主控板修正 缺點:傳送訊號電流太小,造成LED亮度不夠 解決:將BJT改FET(未實行)

  4. ◎Reader架構 – 修正

  5. ◎PCBLayout –Reader修正 修正:1. 兩台Reader相互干擾 解決:1.將R1IN.R2IN 相連與T1 OUT . T2 OUT相連 2.Reader1與Reader2 分開利用MAX232轉換

  6. ◎Zigbee訊號傳送延遲 修正:1.訊號傳送延遲 解決:1. 重新燒錄

  7. ◎Reader架構測試

  8. ◎Reader架構測試 主控板主機

  9. ◎Reader架構測試 Reader1、Reader2主機
