Research on Multi-Sensor Parameter Updating and Firmware Upgrading Method Based on Modbus

In industrial systems, sensors are used as key data acquisition devices. Optimizing their performance and functionality is essential for ensuring stable operation and improving system productivity. In order to realize function expansion, performance optimization and security guarantee, parameter updates, and firmware upgrades are indispensable operations. However, traditional methods for parameter updates and firmware upgrades typically rely on manual operations, which has many drawbacks such as low efficiency, high maintenance cost, and a significant risk of errors. These limitations make it difficult to meet the demands for high efficiency and intelligent equipment management in modern industrial systems. We propose a solution for parameter updating and firmware upgrading based on Modbus protocol, designing and realizing related hardware and Supervisory Control Software systems. The system communicates with the Supervisory Control Software through the LoRa module, utilizing the reliability and standardization characteristics of the Modbus protocol to improve the efficiency of parameter updates and firmware upgrades effectively. The research in this paper provides an efficient and reliable realization path for the intelligent management of sensors in industrial systems and provides an important reference for research and application in related fields.
