重慶飛龍電子網(wǎng)用單片機(jī)設(shè)計(jì)頻率計(jì)

用單片機(jī)設(shè)計(jì)頻率計(jì)

實(shí)驗(yàn)?zāi)繕?biāo)

頻率計(jì)是我們經(jīng)常會用到的實(shí)驗(yàn)儀器之一，本實(shí)驗(yàn)要使用單片機(jī)和計(jì)數(shù)電路及液晶器件來設(shè)計(jì)一個寬頻的頻率計(jì)。

期望達(dá)到10Hz－1.1G范圍的頻率精確測量。

實(shí)驗(yàn)電路圖（初步方案）

1)計(jì)數(shù)及顯示電路：

2）前置放大及分頻電路：

那位大俠有好的電路？？？

設(shè)計(jì)思路

頻率的測量實(shí)際上就是在1S時間內(nèi)對信號進(jìn)行計(jì)數(shù)，計(jì)數(shù)值就是信號頻率。用單片機(jī)設(shè)計(jì)頻率計(jì)通常采用兩種辦法，1）使用單片機(jī)自帶的計(jì)數(shù)器對輸入脈沖進(jìn)行計(jì)數(shù)，或者測量信號的周期；2）單片機(jī)外部使用計(jì)數(shù)器對脈沖信號進(jìn)行計(jì)數(shù)，計(jì)數(shù)值再由單片機(jī)讀取。

由于單片機(jī)自帶計(jì)數(shù)器輸入時鐘的頻率通常只能是系統(tǒng)時鐘頻率的幾分之一甚至幾十分之一，因――――――――――――――――――――――――――――――――――――――――――――――――――

重慶飛龍電子網(wǎng)用單片機(jī)設(shè)計(jì)頻率計(jì)此采用單片機(jī)的計(jì)數(shù)器直接測量信號頻率就受到了很大的限制。

本實(shí)驗(yàn)電路采用方式2，使用一片74LS393四位雙二進(jìn)制計(jì)數(shù)器和Atmega8的T1計(jì)數(shù)器組成了24位計(jì)數(shù)器，最大計(jì)數(shù)值為16777215。如果輸入信號經(jīng)過MB501分頻器進(jìn)行64分頻后再進(jìn)行測量，則固定1S時基下最高測量頻率為1073.741760Mhz。

為了方便得到準(zhǔn)確的1秒鐘測量閘門信號，我們使用了Atmega8的異步實(shí)時時鐘功能，采用32.768Khz的晶振由TC2產(chǎn)生1秒鐘的定時信號。

測量原理：

單片機(jī)打開測量閘門，即PB1輸出高電平，同時TC2定時器啟動。74LS393開始對輸入脈沖進(jìn)行計(jì)數(shù)，74LS393每計(jì)數(shù)達(dá)256時，Atmega8的T1計(jì)數(shù)器也向上計(jì)數(shù)1次。當(dāng)1S定時到達(dá)時，單片機(jī)產(chǎn)生中斷，PB1輸出低電平關(guān)閉測量閘門，然后Atmega8讀取74LS393和T1的計(jì)數(shù)值，然后送LCD顯示。

實(shí)驗(yàn)進(jìn)展

2004-09-27

根據(jù)設(shè)計(jì)思路編寫程序初步獲得了一些實(shí)驗(yàn)結(jié)果，如下圖所示。下圖是測量8M有源晶振的輸出結(jié)果。

由于1S的測量閘門時間在業(yè)余條件下不好測試，因此，實(shí)驗(yàn)程序中在LCD上同時顯示實(shí)時時鐘用于判斷1S閘門時間的準(zhǔn)確性。實(shí)驗(yàn)中，我使用CDMA手機(jī)上顯示的GPS衛(wèi)星精確時間進(jìn)行比較。手機(jī)時間顯示的最小單位是分鐘，測量時一旦手機(jī)分鐘值發(fā)生跳變，則立即記錄下LCD顯示的秒值，這樣的話讓頻率計(jì)運(yùn)行一段時間后，再多次記錄下LCD顯示的秒，就可以準(zhǔn)確判斷頻率計(jì)的異步時鐘是

重慶飛龍電子網(wǎng)用單片機(jī)設(shè)計(jì)頻率計(jì)否準(zhǔn)確。實(shí)驗(yàn)過程中，我讓頻率計(jì)走了10個小數(shù)左右，測量的1S時鐘還是非常準(zhǔn)確的。

實(shí)驗(yàn)問題：實(shí)驗(yàn)測試8M有源晶振的測量結(jié)果如上圖所示，而測試4M普通晶振的測量結(jié)果是3.999932MHz。感覺上好像測量稍稍有一點(diǎn)偏低。
