Automatic ID Configuration Method and System Based on IO Control Detection for Cascaded Photovoltaic and Energy Storage Multiple MCU Systems

Introduction

In recent years, the rapid advancement of photovoltaic and energy storage technology has led to an increasing adoption of cascaded photovoltaic and energy storage multiple MCU systems. However, configuring MCU IDs in these systems has always posed a significant challenge for system developers. Traditional methods, such as relying on isolation communication equipment or dedicated fixtures, are often expensive and come with inherent limitations.

This necessitates the development of a new approach that can achieve automatic ID configuration for multiple MCUs in a cost-effective and flexible manner.

Methodology

The proposed method leverages IO control detection, employing a hand-in-hand chain structure without the need for a CAN bus. This structure enables automatic ID configuration for multiple MCUs within the system. The system comprises a master MCU and multiple slave MCUs, interconnected in a chain formation.

The configuration process initiates with the master MCU sending a trigger signal to the first slave MCU. Subsequently, the slave MCU transmits a response signal back to the master MCU. This pattern continues as the master MCU sends a control signal to the second slave MCU, and so on, until all slave MCUs have been successfully configured.

Results

The proposed system has been implemented and rigorously tested within a cascaded photovoltaic and energy storage multiple MCU system. The results demonstrate the system's effectiveness in achieving automatic ID configuration for multiple MCUs in a cost-effective and flexible manner. Furthermore, the system can be seamlessly integrated into existing systems with minimal modifications.

Conclusion

The proposed automatic ID configuration method and system based on IO control detection offers a cost-effective and flexible solution for achieving automatic ID configuration for multiple MCUs in cascaded photovoltaic and energy storage systems. By eliminating the need for expensive isolation communication equipment and dedicated fixtures, the system simplifies configuration processes and enhances system efficiency. The automatic coding method for MCUs without a host further contributes to streamlining MCU ID configuration, making it more efficient and automated. This research presents a valuable contribution to the field of cascaded photovoltaic and energy storage systems, offering a practical and innovative approach to MCU ID configuration.
