* 標(biāo)題: 基于SIM900A的自動(dòng)充電提醒以及實(shí)時(shí)查詢(xún)電量裝置 *
* 時(shí)間 2018年10月10日16:12:42 *
* *
* 實(shí)驗(yàn)說(shuō)明：本裝置的核心是SIM900A模塊，需要調(diào)用SIM900A指令。本原理圖中ADC0832 *
的參考電壓為5V,由7805穩(wěn)壓源提供7805的電源以及參考電壓。檢測(cè)電池的電壓在9-15V之 *
間，采用分壓方式，一個(gè)30K,一個(gè)10K電阻進(jìn)行分壓。假如檢測(cè)電壓為15V,則輸入ADC0832 *
的電壓為5V。依次類(lèi)推。 *
*
********************************************************************************
* 實(shí)驗(yàn)心得：SIM900A是個(gè)難點(diǎn)，需要在電腦上進(jìn)行調(diào)試。ADC0832進(jìn)行AD轉(zhuǎn)化的時(shí)候，需 *
要研究下時(shí)序圖，在進(jìn)行數(shù)據(jù)檢測(cè)的時(shí)候需要進(jìn)行兩次檢測(cè)，如果前后兩次數(shù)據(jù)相等，那 *
么再返回得到的值，減少了測(cè)量誤差。7805穩(wěn)壓源是個(gè)重要的部件，為了提供精確穩(wěn)定的 *
5V參考電壓 *
