Problems solved by technology

[0002] At present, most of the high-end landscape lighting DMX512 lighting control hosts on the market use buffer unit + MCU to realize the lighting effect interpretation control of large data volume, and the external media lighting data uses SD card, CF card, and Ethernet interface to realize data transmission. The transmission path is that the MCU analyzes the external media lighting data stream and then forwards it to the cache unit for data caching. Since the media lighting data needs to be parsed by the MCU before data caching, the processing bandwidth of the MCU greatly limits the media lighting data. Cache efficiency; at the same time, most of the current lighting control hosts basically do not have master / slave dual backup interfaces. Access Control for External Devices

technical field [0001] The invention relates to landscape lighting lighting control technology, in particular to a multi-functional landscape lighting control device and its realization method. Background technique [0002] At present, most of the high-end landscape lighting DMX512 lighting control hosts on the market use buffer unit + MCU to realize the lighting effect interpretation control of large data volume, and the external media lighting data uses SD card, CF card, and Ethernet interface to realize data transmission. The transmission path is that the MCU analyzes the external media lighting data stream and then forwards it to the cache unit for data caching. Since the media lighting data needs to be parsed by the MCU before data caching, the processing bandwidth of the MCU greatly limits the media lighting data. Cache efficiency; at the same time, most of the current lighting control hosts basically do not have master / slave dual backup interfaces. Access control for...
