众所周知，现在不管是企业、工厂，还是家庭，都基本上实现了自动化，即一些智能化的设备被使用，这样为使用者提供了极大的方便。智能化，就是让处理单元代替了人的思维与操作，来控制外部设备工作。
继电器，就是一个典型的实例（现代自动化控制设备中都存在一个电子与电气电路的互相联结问题，一方面要使电子电路的控制信号能够控制电气电路的执行元件(电动机、 电磁铁、电灯等)；一方面又要为电子电路的电气提供良好的电隔离， 以保护电子电路和人身的安全，电子继电器便能完成这一桥梁作用）。

Actual problem ability contacting actual solving by the fact that graduation practice, improves theory; Going deep into waiting for relevance hardware knowledge to interface technology understands rise; Have 8279's control words interposition , mechanics , programming principle and PC interface method in hand. Deepen the characteristic and operating principle understanding the successive approximation law modulus converter's , have the ADC0809 interface method and A/D input program design in hand and test method. It is known to all that not caring now is enterprise , a factory , is still a family, having realized an automation mainly , be that a little intellectualized equipment has been used , such has been provided immense going to the lavatory to the user. Thought and operation intellectualized , being to have let treatment element replace person, come to control the outside equipment job.
The relay, is that a representative example (modern times automates to have circuital mutual a electron and electricity linkup problem in control system , one side needs to make the electronic circuit pilot signal be able to control the circuital electricity implementation component (electric motor , electromagnet , electric lamp etc.); Electricity being going to be an electronic
