システム設計コンセプト

The design of the solar wireless signal system has evolved from exploration to innovation. Early wireless signal systems, due to backward communication technology, had issues such as high error rates and limited communication distances. Furthermore, lacking integration with solar power technology, these wireless signal systems could not fully utilize their wireless advantages. Through a deep understanding of the system and various wireless technology experiments, we finally selected a design scheme implemented with wireless communication components and protocols. After multiple tests and improvements, the solar wireless signal system achieved functions such as self-organization, self-detection, and self-recovery, reaching the goal of high-reliability distributed wireless control.

Hardware and Software Design

The key to the system's hardware and software design lies in the design of the wireless communication protocol. We employed methods such as asynchronous serial communication, power-on verification, scheme transmission, fault diagnosis processing, and timing inspection to ensure the strictness and reliability of the protocol, guaranteeing the system's self-organization, self-detection, and self-recovery capabilities. The master hardware includes a microcontroller, CPLD interface control chip, wireless communication module, etc. The master software consists of the main program and multiple interrupt programs, while the slave hardware is composed of a microcontroller and wireless communication module, among other components. The slave software mainly includes the main program and interrupt service routines.

Solar Power Supply System

The design of the solar power supply system fully considers factors such as the maximum power load of the power source, the discharge time of the battery, the charging time of the solar panel, as well as the local sunshine conditions and latitude, ensuring high efficiency and reliability in power control.

Conclusion

Combining solar power with wireless communication technology, the Jerry Solar Wireless Signal System achieves distributed control. Compared with traditional systems, this system adopts a more reliable scheme-based response wireless communication protocol and, through various self-diagnosis and recovery designs, exhibits excellent lightning and interference resistance, with strong system self-organization and self-recovery capabilities. Particularly, by incorporating solar power technology, it becomes more energy-efficient and environmentally friendly, fully aligning with national energy policies. As the system truly achieves cable-free connections between subsystems, it greatly reduces the costs associated with laying pipelines and cables, making the overall cost much lower than that of traditional municipal power systems. Therefore, this is a practical and cost-effective innovative product that has already been applied in several countries, including Bulgaria and Nigeria, as well as domestically, receiving positive feedback. As the market continues to recognize this product, the application prospects for solar wireless signal systems will become even broader.
