中文摘要 | 本文研究一種學習型紅外線遙控四通道功率控制及定時裝置的製作,它是一個 附有電子時鐘的定時開關,也是一個電源功率控制器,可同時控制四個電器。採用任意一 般家用的紅外線遙控器,經過學習記憶,即可控制電源的開斷,可分八段調節輸出的功率 ,並可調整對時,預定開關的自動通電時刻及自動斷電時刻。 本裝置的硬體部分以8051單晶片處理器為中心,加上紅外線接收模組、零交越偵測電 路、交流電源控制開關、LCD顯示模組、及5Volts直流電源構成。軟體程式部分,採用計 時器計算交流電源的觸發角,以相位控制方式控制輸出功率。以8051內的計時器計時,構 成電子時鐘,組成定時開關。另外,程式採中斷方式讀取紅外線訊號以學習、記憶、及辨 識按鍵碼。本文的重點在於紅外線訊號的學習記憶,以軟體的方式,記憶紅外線訊號的特 性時距,進而判斷並記憶其按鍵碼,以便能採用任意家用紅外線遙控器控制本裝置。 |
英文摘要 | This study coustructs a learning-type infrared remote controller, which is a time switch with a clock showing current time and is able to regulate the output power levels of four sets of AC power outlets. Any of the four channels can be preset for on-time, on-power level and off-time. The hardware of this device consists of 8051 single-chip microprocessor, infrared receiver module, zero-crossing detection circuit, AC power switch unit, LCD display module, and 5 volt DC power supply. In software design, a timer is used to measure the phase angle of the AC power to control the output power by phase control method. Another timer in 8051 is used to form a digital clock. With the digital clock and AC power switch unit, a time switch is formed. The signals from the infrared receiver module cause interrupts in 805 1. The interrupt subroutine learns the format of the transmitted signals. This research focuses on the training of the infrared remote controller. The format of the transmitted signal is recognized first, then the key code is extracted. Any domestic infrared remote controller can be used to control this device. |
