【正文】 。無線門鈴不僅安裝和使用方便， 而且無線遙控 門鈴能發(fā)出各種不同的優(yōu)美音樂，用戶可以通過轉(zhuǎn)換開關(guān)選擇喜歡的音樂。 傳統(tǒng)的門鈴都為有線門鈴，雖然它也極大的方便了我們的日常生活， 然而在一些已裝修好的室內(nèi) ， 由于 傳統(tǒng)的門 鈴布置采用導線將門鈴的各個 設備 連接到一起需要布線， 從而破壞裝修，讓人感到非常麻煩。 隨著經(jīng)濟的發(fā)展，人們的生活水平 也 在不段提高， 對產(chǎn)品的要求也越來越高，有線門鈴已不在是消費者心目中滿意的產(chǎn)品，更多的消費者追求更方便，性能更好的無線 遙控 門鈴，進而市場上的無線門鈴也越來越多。無線音樂門鈴解決了這種尷尬，方便主人在房內(nèi)各地使用，將門鈴按 鈕安裝在門上，來訪者只要按下按鈕，放在客廳、廚房或臥室的接受主機就會響起“叮咚”聲或樂曲聲，宏亮悅耳，告知有客人來了，距離在幾米到幾十米，一般都有 15 到 20 米的距離。傳統(tǒng)的門鈴都為有線門鈴，使用方便，極大地方便了大家的生活。也有的是由IC 片播放一段電子音樂的。各式各樣的“門鈴”比比皆是。s living standards greatly improved, people living environment of safe, convenient and there are more and more requirements, mainly reflected in the intelligent residential, people with a view to a safe and reliable, use convenient wait for an advantage in one intelligent wireless remote control doorbell products, so the music doorbell system design has bee the goal of this research. This paper introduces a new wireless remote control doorbell music, it has function of coding remote control transmitter receiver ASIC. Combi ned with high electromechanical music doorbell sound source, bee a kind of sound, the doorbell button and between the sound source is removed from the connection, convenient installation of the new remote control doorbell the doorbell sound quality with low power consumption., the circuit is simple and reliable, strong antiinterference capability, remote control distance, circuit the advantages of small size, the receiving circuit together with electromechanical music doorbell for one, can be placed in the interior of a place, also can transform a variety of music doorbell, make sound, meet different people 39。具有性 能穩(wěn)定、功耗低等特點。 這種門鈴具有功耗低 ,電路簡單可靠 ,抗干擾能力強 ,遙控距離遠 ,電路體積小等優(yōu)點 ,其接收電路連同機電式音樂門鈴為一體 ,可以隨意放置在室內(nèi)的某個地方 ,還可變換各種門鈴音樂，使聲音悅耳動聽，滿足不同人群的生活需要，具有廣闊的發(fā)展前景。 無線遙控門鈴的設計 摘 要 隨著微電子技術(shù)、無線技術(shù)和網(wǎng)絡技術(shù)的飛速發(fā)展以及人們生活水平的大幅度提高，人們對居住環(huán)境的安全、方便也有了越來越多以及越來越高的要求，主要體現(xiàn)在智能化住宅中，人們著眼于一種安全可靠、使用方便等優(yōu)點于一體的智能化門鈴產(chǎn)品，因此無線遙控音樂門鈴系統(tǒng)的設計成為本課題研究的目標。 本文介紹了一種新型無線遙控 門鈴 ,它采用具有編碼功能的遙控發(fā)射 接收專用集成電路 .結(jié)合高音質(zhì)機電式音樂門鈴做聲源 ,成為一種聲音動聽、門鈴按鈕與聲源之間免去連線、安裝方便的新型遙控高音質(zhì)門鈴 。 該無線音樂門鈴用 PT2262/PT2272 集成芯片作為發(fā)射和接收主電路，還有 F05V 和J05V 超外差發(fā)射和接收模塊。 關(guān)鍵詞 ： 無線遙控 ,PT2262, PT2272, FO5V, J05V The design of the wireless remote control doorbell Abstract With microelectronic technology, wireless technology and the work technology rapid development and people39。s needs, have wide development prospect. The wireless door chime with the PT2262 / PT2272 integrated chip for transmitting and receiving circuit, and F05V and J05V Super heterodyne transmitter and receiver module. Has the advantages of stable performance, low power consumption.
