[0044] As a preferred technical solution, the single-terminal LED controller has a built-in non-volatile memory.

[0045] Here’s how:

[0046] A method for controlling an LED lamp uses the LED lamp control system to control the LED lamp.

[0047] As a preferred technical solution, the following control methods are included:

[0048] a. Online control, the platform sends logical control commands in real time:

[0049] The platform management system generates a logic control command and sends it to the wireless gateway, which transmits the logic control command to the single-terminal LED controller. The single-terminal LED controller then parses and executes the received logic control command to control the LED light.

[0050] b. Local mode, the single-terminal LED controller autonomously controls the LED light according to preset parameters:

[0051] The single-terminal LED controller has a built-in memory to store the lighting parameters for controlling the LED lamp. The platform management system generates a logic control command to trigger the local mode and sends it to the wireless gateway. The wireless gateway transmits the logic control command to the single-terminal LED controller. The single-terminal LED controller parses and executes the logic control command and autonomously controls the LED lamp according to the lighting parameters that have been downloaded to the memory.

[0052] c. Beat mode:

[0053] In the first step, the platform management system generates display effects and control parameters;

[0054] In the second step, the platform management system generates logic control commands and control parameters and sends them to the wireless gateway during idle time. The wireless gateway transmits the logic control commands and control parameters to the single-terminal LED controller, which parses and stores the logic control commands and control parameters.

[0055] In the third step, when it is necessary to play the lighting effects, the platform management system issues the program scheduling instructions and the play beat broadcast, and the single-terminal LED controller synchronizes the program scheduling instructions and time with the wireless gateway.

[0056] As a preferred technical solution, during the charging process, the single-terminal LED controller collects the charging voltage and light intensity in real time, and transmits the collected charging voltage and light intensity to the platform management system through the wireless gateway. The platform management system counts the charging power based on the received charging voltage and light intensity, and calculates the operating time of the single-terminal LED controller based on the remaining power of the single-terminal LED controller and the dynamic current consumption of the single-terminal LED controller.

[0057] More specifically, as follows:

[0058] 1. The present invention is energy self-sufficient and integrates a solar photovoltaic management system. The solar photovoltaic management system includes solar photovoltaic panels, MPPT solar managers (Maximum power point tracking, referred to as MPPT, MPPT solar managers are solar managers with MPPT functions), and rechargeable lithium batteries.

[0059] By converting solar energy into voltage output through solar photovoltaic panels, the MPPT solar manager dynamically adapts the load according to different light conditions, realizes efficient energy conversion from light to electricity, and converts electrical energy into chemical energy and stores it in the battery. It charges during the day and discharges at night, achieving self-sufficiency of energy for a single LED terminal.

[0060] During the daytime charging process, the single-terminal LED controller collects data such as charging voltage and light intensity in real time, and transmits the collected data to the platform management system through the Wiota network. The platform management system calculates the charging power based on the received data and the dynamic data of the charging voltage, and calculates the operating time of the single-terminal LED controller based on the remaining power of the single-terminal LED controller and the dynamic current consumption of the single-terminal LED controller, and then analyzes and gives a night control display strategy.

[0061] 2. Control method:

[0062] a. Online control, the platform issues logical control commands in real time.

[0063] The platform management system generates a logic control command and transmits it to the local single-terminal LED controller in real time through the wireless control link WioTa protocol. After receiving the logic control command, the local single-terminal LED controller parses and executes the logic control command to realize light control.

[0064] b. Local mode, the single-terminal LED controller autonomously controls the light according to preset parameters.

[0065] The single-terminal LED controller has a built-in non-volatile memory to store the parameters for controlling the light. This mode is triggered by sending a logic control command through the platform management system. The single-terminal LED controller can cyclically run the built-in light control parameters according to the set parameters and autonomously control the light changes according to the light parameters that have been downloaded to the memory.

[0066] c. Beat mode:

[0067] In the first step, the platform management system generates logical control commands and control parameters;

[0068] In the second step, the platform management system sends the generated logic control commands and control parameters through the gateway during idle time. After sending the logic control commands and control parameters, they are stored in the single-terminal LED controller;

[0069] In the third step, when it is necessary to play lighting effects, the platform management system issues program scheduling instructions and playback rhythm broadcasts. The single-terminal LED controller uses the Wi oTa protocol to synchronize program scheduling instructions and time with the wireless gateway, so that multiple LED lights can coordinate and play programs at the same frequency, achieving the effect of multiple LED lights being linked.

[0070] Example 2

[0071] like Figures 1 to 3 As shown, based on Example 1, this example provides a more detailed implementation method.

[0072] This embodiment takes the application of building lighting engineering as an example.

[0073] The single-terminal LED controller integrates a solar charging function, obtains electricity through sunlight, and provides electricity for the single-terminal LED controller (such as controller communication chip, processor), LED lights, etc.

[0074] The present invention adopts LTE / 5G public network + WioTa synchronous communication protocol. LTE / 5G is a public network communication, connecting the wireless gateway and the platform management system. The wireless gateway and the single-terminal LED controller adopt the local area network WioTa communication protocol. The WioTa communication protocol supports unicast and broadcast modes.

[0075] The platform management system generates logical control command data and sends it down through the communication link. The single-terminal LED controller controls the LED online real-time display according to the received control command. The platform management system can dynamically adjust the control data according to the display effect.

[0076] After synchronization with the wireless gateway, the LED control information generated by the stored control data is displayed locally based on the clock control beat and beat mode. The single LED terminal and cluster multi-LED terminal linkage are realized to achieve complex display effects such as monochrome, multi-color, breathing light, running light, graphics and images.
