SYSTEM¶

Note

Note that currently the hardware and software design are being developed separately and simultaneously, and the software part is currently being developed based on existing ESP32 development boards on the market, which will be adapted to our designed hardware platform in the future.

Note

The current version is 1.0. Its primary goal is to support scientific research and algorithm validation. There is still a significant gap before real-world field deployment and commercial use. The system will be adjusted and optimized later based on practical requirements and constraints.

Physical Structure¶

We use a three-board design, which are:

Power Board¶

Responsible for providing stable power supply to the entire system, supporting both battery and wired power supply, and featuring power management functions to optimize energy consumption and extend battery life. (This board is directly purchased from a third-party power management board, and may be custom-designed later based on actual needs)

Main Control Board¶

Equipped with the ESP32S3 chip, responsible for the core processing and control of the system, while also providing common basic functions such as storage and basic status feedback. The communication functions are also provided by the main control board, supporting common communication methods such as Wi-Fi and Bluetooth.

Expansion Board¶

Provides various interfaces and expansion functions, supporting the connection of various sensors and actuators. The expansion board can be redesigned according to task needs to accommodate different sensors and actuators.

System Architecture¶

The system architecture is divided into the following parts:

Main Control System¶

Microcontroller chip or module - based on ESP32S3
