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一部分电路，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，在它的旁边有品振元件的，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国就是微控制器电路。

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

The function of the power supply circuit is to convert 220VAC or 380VAC alternating current into various DC with constant output voltage of+5V.12V.18V.24V required by the circuit board.

Input interface circuit: The input interface circuit is a part of the circuit for information exchange and communication between the circuit board and the outside world. It can convert what people want to say or do to the circuit board into electrical signals that can be recognized by the microprocessor in the circuit board. For example, when we are monitoring the temperature, if you tell it to the microprocessor in the language that we usually communicate with each other, please turn it down a little, because the microprocessor can't understand what we are saying. At this time, we can first convert the temperature signal into an electrical signal with thermistor or thermocouple through the interface circuit, and then process the converted electrical signal to get the electrical signal that the microprocessor can recognize. In this way, after the microprocessor understands what we want it to do, it can do what we want. Other signals such as illumination, pressure, wind, liquid level, position and so on are the same.

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

Microprocessor control circuit: Microprocessor control circuit is mainly used in the circuit board of the main control board. When we see a square or rectangular-shaped component with many pins in the circuit board, there is a vibrating element next to it. This component is mostly a microprocessor component, and Zhou Guo, with a microprocessor as the core component, is a microcontroller circuit.

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