Application Research of Domestic Digital Quantity Acquisition Controller Under the Background of Innovation

Based on the background of information innovation, the development of intelligent sensing technology science is studied to provide agricultural modernization and intelligent transformation technologies with high quality, strong reliability, high cost performance and rich applicable scenarios for the national agricultural Internet of Things control, industrial automation, instrumentation and other industries. This project uses domestic components as the structural basis and domestic single-chip microcomputer chips as the main control carrier. It innovatively integrates autonomous controllable technology and uses the MODBUS protocol to achieve reliable data exchange between the controller and other devices. It designs a domestic digital quantity acquisition controller that can support 6-way isolated digital input interface, 12-way isolated digital output interface and 1-way 485 isolated communication, and is compatible with the standard MODBUS protocol, variant MODBUS protocol and protocol switching in different scenarios. It can not only meet the domestic and foreign market's demand for safety and reliability, but also greatly contribute to the autonomous controllability and technological innovation in my country's information technology field, and realize the sustainable development of autonomous controllable systems.
