發(fā)展，安防逐漸受到人們的重視。防盜報警器也從之前的有線變化到現(xiàn)在的無線。而且應(yīng)用的范圍也越來越廣，從家庭防盜到高檔小區(qū)防盜等一系列需要安防的地方。本文采用了 紅外熱釋電傳感器采集數(shù)據(jù)、 NRF24L01無線傳輸數(shù)據(jù)以及單片機控制技術(shù)，研制了基于單片機的無線防盜報警器。設(shè)計涵蓋了數(shù)據(jù)采集、數(shù)據(jù)傳輸、數(shù)據(jù)輸出三大模塊。其中數(shù)據(jù)輸出以報警的形式體現(xiàn)出來。報警器采用了聲音報警系統(tǒng)和發(fā)光二極管報警系統(tǒng)結(jié)合的方式來進行報警。整個設(shè)計原理是通過 STC89C52RC單片機將傳感器采集的數(shù)據(jù)進行整理，然后傳送到報警系統(tǒng)，實現(xiàn) 報警功能。 關(guān)鍵詞 ： 無線防盜報警；熱釋電紅外傳感器；單片機；無線傳輸 王成龍：基于單片機的無線防盜報警器的設(shè)計 2 Wireless burglar alarm MCUbased designs Abstract: With the development of society, the security has been paid more and more antitheft alarm also changes from the previous to the current more and more wide range of applications,from the family security to highend residential security and a series of security where paper uses the pyroelectric infrared sensor data acquisition,NRF24L01 wireless data transmission andmicrocontroller control technology, developed a wireless antitheft alarm system based on design includes data acquisition,data transmission,data output module three. The data output in the form of alarm. Alarm with sound and light emitting diode alarm system alarm system bined to alarm. The design principle is through the STC89C52RC MCU the sensor data, and then sent to the alarm system, alarm function. Key words:Wireless burglar alarm。Pyroelectric infrared sensor。microcontroller。 Wireless transmission 蚌埠學(xué)院本科畢業(yè)設(shè)計（論文） 3 基于單片機 的無線防盜報警器的設(shè)計 1 引 言 本課題研究背景
