The Implementation and Application of Modbus Protocol in DC Panel Based on μC/Os-II
Abstract:
This paper introduces the basic concepts and functions of the DC panel. Then introduce the role of Modbus protocol in the DC panel. After that, the scheme concept and hardware platform of the protocol implementation are analyzed. And then this paper explains the realization of Modbus protocol in DC panel system that ported μC/OS-II based on ARM Cortex-M3. Due to DC panel system has multi-tasking and large amount of monitoring data, the concurrent problems handling multiple tasks in the μC/OS-II are analyzed and designed. Finally, the communication is implemented via DC panel battery module with DC panel system used in the program. The results show that the implementation of the protocol can achieve real-time and stable effects.
