Control System of Bamboo Splitting Machine Based on STM32 and HMI

The general control system of bamboo splitting machine is controlled by Programmable Logic Controller (PLC), which is one of the most expensive devices in industrial automation control system. For some small enterprises or occasions with limited budget, the cost may become a limiting factor. Moreover, the technical threshold is high. Programming and debugging of PLC require professional technical personnel, and a relatively solid theoretical foundation of automation control is needed. Therefore, for some enterprises with lower technical levels, the use and maintenance may pose certain difficulties. To solve this problem, we have designed a set of bamboo splitting machine control system based on STM32 and touch screen. In the selection of HMI hardware, we choose a 2K touch screen with support for ten-point touch on the notebook computer, and equipped with a 64-bit processor chip i5-1135G7 based on the Intel core as the core processor. In terms of touch interface design, we introduce the comprehensive design of database technology and HMI interaction technology. In terms of HMI software interface programming, we adopt the method of object-oriented programming to achieve data communication transmission with the touch screen, upper computer and equipment. Through the Modbus-crc16 communication protocol, direct communication between STM32 and computer touch screen hardware is achieved. After debugging, the system runs stably with fast response speed and wide applicability. It reduces the reliance on traditional HMI hardware and speeds up the product development cycle. The design can achieve the desired display and control effects in the bamboo splitting machine system, providing a new way for the development of the bamboo splitting machine control system.
