电源供应电路:电源供应电路部分电路是向整个电路板中各个单元电路提供能量的-部分电路，它工作在高电压、大电流的环境下，是最容易出故障的一部分电路。

电源供应电路的功用是:将220VAC或380VAC交流电 转换成电路板所需的各种不同等级、输出电压恒定的+5V、12V、 15V、 18V、 24V等级别的
直流电。

输入接口电路:输入接口电路是电路板和外界进行信息交换和沟通的一部分电路, 它可以将人们想要对电路板所说的话或要办的事转化成电路板中微处理器能够识别的电信号。例如:我们在监控温度高低时，你如果用咱们平常人与人交流的语言说给微处理器听,温度高了，请把它调低一些,微处理:是听不懂咱们说的话的，这时，我们可以通过接口电路先用热敏电阻或热电偶元件将温度信号转成电信号，然后在对所转换出电信号进行处理，就可以得到微处理器可以识别的电信号了。这样的话微处理器明白了我们要它处理的事项后，他就可以按照我们的意图去做了。其它的像光照度、压力、风力、液位、位置、等信号都是同样道理。

输入接口电路的功能是:将人们想要对电路板所说的话或要办的事转化成电路板中微处理器能够识别的电平信号。

微处理器控制电路:微处理器控制电路主要用在主控制板电路板中，当我们看到电路板中模样长得四四方方或长方形形状、有很多引脚的元件,在它的旁边有晶振元件的,这个元件大多是微处理器元件，以微处理器为核心元件的周围就是微控制器电路。

微处理器控制电路主要功能是:接受输入接口电路发送过来的相关信息，并对这些信息进行分析、处理，并作出相应的处理结果，把处理结果进一步
送给输出接口电路。

Power supply circuit: The power supply circuit is a part of the circuit that provides energy to each unit circuit in the entire circuit board. It works in a high voltage and high current environment and is the part of the circuit that is most prone to failure.

The function of the power supply circuit is to convert 220VAC or 380VAC AC into various different levels required by the circuit board, and the output voltage is constant at +5V, 12V, 15V, 18V, 24V levels
Direct current.

Input interface circuit: The input interface circuit is a part of the circuit board and the outside world for information exchange and communication, which can convert what people want to say or do to the circuit board into an electrical signal that the microprocessor in the circuit board can recognize. For example: when we are monitoring the temperature, if you use our ordinary human communication language to say to the microprocessor, the temperature is high, please turn it down a little, micro-processing: it is not able to understand what we say, at this time, we can first use the interface circuit to convert the temperature signal into an electrical signal, and then process the converted electrical signal. You get an electrical signal that the microprocessor can recognize. That way, once the microprocessor understands what we want it to do, it can do what we want it to do. The same is true of other signals such as illumination, pressure, wind, liquid level, position, and so on.

The function of the input interface circuit is to convert what people want to say or do to the board into a level signal that the microprocessor in the board can recognize.

Microprocessor control circuit: microprocessor control circuit is mainly used in the main control board circuit board, when we see the circuit board in the shape of a square or rectangular shape, there are many pin components, next to it there are crystal components, this component is mostly microprocessor components, microprocessor as the core component around the microcontroller circuit.

The main function of the microprocessor control circuit is to accept the relevant information sent by the input interface circuit, and analyze and process the information, and make the corresponding processing results, and further the processing results
Send to output interface circuit.
