Abstract
Description
Technical Field
[0001] This invention relates to the field of information transmission technology, and specifically to a method for automatically writing addresses to LED lamps using only a two-core power supply wire. Background Technology
[0002] The common method for automatically writing addresses to LED lights typically uses a 5-core wire, including two power cores, two signal cores (A / B), and one input / output PI / PO line. This method is not only costly but also significantly more complex in its manufacturing process. This alternative approach can achieve cost reduction and efficiency improvement. Summary of the Invention
[0003] The purpose of this invention is to provide a method for automatically writing addresses to LED lamps using only a two-core power supply wire. This solves the problem that common methods for automatically writing addresses to LED lamps typically use a five-core wire, including a two-core power supply wire, a two-core A / B signal wire, and a PI / PO wire (one input and one output). This method is not only costly but also involves a complex manufacturing process.
[0004] To achieve the above objectives, the present invention provides the following technical solution: A method for automatically writing addresses to LED lamps using only a two-core power supply wire includes the following steps: S1. The main controller is powered on and outputs V+ and V-. All decoding devices are connected via V-. S2. The power supply V1+ to decoding device 1 is directly connected to V+. When MCU1 powers on and turns off S1, it supplies power V2+ to decoding device 2. When MCU2 powers on and turns off S2, it supplies power V3+ to decoding device 3, and so on, until MCUn powers on and turns off Sn. At this point, all decoding devices start to work. S3: The main controller broadcasts a start coding signal, and all decoding devices turn off their S switches and stop supplying power to the subsequent decoding devices. S4. The main controller sends the address, channel, and other relevant information of the decoding device via the V+ line; S5. The V1+ of the decoding device 1 is directly connected to the V+ of the main controller. The MCU1 can receive the information from the main controller, save the information, and then turn on the S1 switch to supply power to the decoding device 2. S6. Decoding device 1 overlays address information and sends it to decoding device 2 via the V2+ line; S7. After the MCU2 of the decoding device 2 receives and saves the information, it turns on the S2 switch to supply power to the decoding device 3. S8. Decoding device 2 overlays address information and sends it to decoding device 3 via V3+ line; S9. After the MCU3 of the decoding device 3 receives and saves the information, it turns on the S3 switch to supply power to the decoding device 4. S10, Decoding device 3 superimposes address information and sends it to decoding device 4 via V4+ line; S11, and so on, until the MCUn of the decoding device n receives and saves the information; at this point, the automatic address writing is completed.
[0005] The beneficial effects of this invention are as follows: This application, through the automatic address writing function of LED lighting fixtures, reduces the number of wires from 5 cores to 2 cores, saving product costs, optimizing the production process, and greatly improving the flexibility and convenience of wiring. In situations requiring large-scale deployment of LED lighting fixtures, such as commercial lighting and urban landscape lighting, there is no need to worry about complex wiring; a simple two-core wire connection is sufficient to achieve automatic address writing and intelligent control of the lighting fixtures. Furthermore, this method has good scalability and compatibility, allowing for easy integration with various LED lighting fixtures and control systems, providing strong support for the intelligent and networked development of modern lighting systems.
