[0026] The wired communication module is an RS485 to USB adapter, used for debugging and external communication.

[0027] In this embodiment, the industrial control computer (model: IPC-610) serves as the core control unit of the system. It communicates with each relay unit through the ZigBee wireless module (ConBee II) and can issue control commands, codes, and other related control commands.

[0028] The power adapter (24V / 5A) and uninterruptible power supply (UPS) provide power to the industrial computer and its connected equipment, ensuring the stable operation of the system.

[0029] The relay unit includes a relay controller, a relay unit switching power supply, an uplink DTU, and a downlink DTU. Both the uplink DTU and the downlink DTU are connected to the relay controller. The uplink DTU communicates with the wireless communication module through a wireless communication network.

[0030] The uplink DTU, downlink DTU, and drive unit DTU are all model E18-DTU Z27-485, and the relay controller and drive controller are all model STM32F103C8T6.

[0031] In this embodiment, the relay controller (STM32F103C8T6) is responsible for managing and controlling the communication of the relay units. The uplink DTU (E18-DTU Z27-485) communicates with the wireless communication module of the control center to transmit control commands and reception status information issued by the control center. The downlink DTU (E18-DTU Z27-485) communicates with the drive unit DTU of the drive unit to transmit control commands and reception feedback information of the relay units.

[0032] The relay unit switching power supply provides power to the relay controller, uplink DTU, and downlink DTU;

[0033] The drive unit includes a drive unit switching power supply, a drive controller, a drive unit DTU, and several drivers.

The industrial computer in the control center establishes a communication connection with each relay unit via the ConBee II wireless communication module. After the communication link is established, the control center can send control commands to the relay units via the ZigBee wireless communication module, such as turning lights on and off or adjusting brightness. After receiving the commands, the relay units send control signals to each drive unit via the downlink DTU. After receiving the commands, the drive units control each LED driver to perform the corresponding operations. Each drive unit can feed back the operating status information of the LED light fixture to the relay unit, which then transmits the information back to the control center. The industrial computer displays the system's operating status in real time on a display screen and allows for manual intervention when necessary.
