Hydraulic Machine Controller
This project aims to transform the operational efficiency of hydraulic pressing machines by introducing a Microcontroller Unit (MCU)-based solution. The goal is to semi-automate the pressing process while providing real-time data display and user-customizable pre-settings, significantly enhancing precision, safety, and user interaction.
Core Components:
STM32F4 Series MCU:
An industrial-grade and cost-effective MCU responsible for seamless data acquisition, computational management, and actuation of output devices.
Linear Encoder:
A high-precision digital readout encoder that measures pressure cylinder movement with up to 5µm accuracy.
High Precision Analog-to-Digital Converter (ADC):
Reads data from industrial-grade pressure sensors with high accuracy, crucial for calculating the precise movements of the hydraulic cylinder.
LCD Display:
A compact yet accurate colour display that shows real-time data, enhancing user interaction and machine control.
Structural and Circuit Design:
PCB Layout:
The total electronics are efficiently distributed onto two PCBs, labelled as the “Independent Basic Controller Section” and the “Automated Data Handling Section”. This design allows for cost-effective end-products tailored to meet diverse user requirements.
Controller Board Design:
