The main control module is the core part of the control system, which is responsible for the instruction and decision of the whole system. The following is a detailed explanation of the main control module:

Definition and composition:

PDP800 main control module is the core of the control system, it controls the work of each module of the system through the program.
The main control module is generally composed of single chip microcomputer, embedded processor, FPGA, DSP and other chips, which can realize complex algorithm operation and control functions.

Core devices:

The core device of the main control module is the main control chip, also known as the microcontroller (MCU) or central processing unit (CPU).
The main control module also includes USB power supply circuit, power decoupling circuit, buzzer alarm circuit, program start circuit, data storage circuit and storage backup circuit.

Main functions:

Overall control and management of the system.
Read and process signals from sensors or user input.
Update the output control signal in real time according to the program algorithm.
Integrate multiple modules to achieve multiple functions.
Communication and interaction:

Application scenario:

PDP800 master control module is widely used in industrial control, electronic manufacturing, automatic production, robot control, intelligent building, intelligent transportation and other fields.

For example, in an intelligent building, the main control module can complete tasks such as lighting adjustment, air conditioning control, access control, monitoring system and data analysis.

Design and development:
The design and development of industrial main control board module need to consider the onboard module, communication interface, power management and software design.
The onboard module contains the necessary hardware components such as processor, memory and communication interface.
Communication interfaces need to support multiple protocols to meet different communication requirements.
The PSU provides intelligent sleep, power consumption monitoring, and intelligent startup.
Software design needs to pay attention to real-time, reusability, upgradability and testability.
Relationships with other components:
The main control module is different from the controller. The controller usually controls and manages a specific link, while the main control module controls and manages the system as a whole.
In some systems, such as ultrasonic imaging systems, the main control module holds the probe parameters, scanning mode, focusing technology, etc., and the phase-controlled delay, conditioning circuit, acquisition card, data processing and imaging module work together to affect the imaging quality of the system.
