- 功率开关管的集电极是一个强干扰源，开关管的散热片应接到开关管的发射极上，以确保集电极与散热片之间由于分布电容而产生的电流流入主电路中。为减少散热片和机壳的分布电容，散热片应尽量远离机壳，如有条件的话，可采用有屏蔽措施的开关管散热片。-power switch of the collector is a strong source of interference, the switch of the Thermal unit received should switch emitter, to e

- 本论文设计了由AT89C52单片机为控制核心,用红外线为监测装置的防盗报警系统。该系统中红外对管作为红外线的发射和接收部分。发射部分采用红外发光二极管，而使用光敏三极管作为接收部分，接收红外发光二极管发出的红外线（不可见光）。单片机将通过内部的软件系统检测到接收管的导通或截止状态,并根据检测到的信号状态,进行判断并输出报警信号, 直至按复位按钮或电源开关。声光报警信号由9014三极管驱动构成声光报警电路,进行声光同时报警。电源部分采用变压器将220V交流市经变压器降压，桥式整流器整流，电解电容滤
