Abstract

The invention belongs to the technical field of landscape decorative lamp control and provides a landscape decorative lamp system and an address coding and display control method of the landscape decorative lamp system. A plurality of display modules comprising master control modules are adopted by the landscape decorative lamp system; display data are obtained from a controller by the display modules in a parallel connection mode; address coding operation is conducted on the display modules at a time in a series connection step-by-step transmission mode; if the master control module in one display module fails, the master control modules in the other display modules can normally conduct corresponding display according to stored address coding data and the display data obtained from the controller, so that the problem that when series connection step-by-step transmission is conducted on the received display data by an existing landscape decorative lamp system, due to driver chips of one or more decorative lamps fail, the following decorative lamps cannot normally work is solved.

Description

technical field [0001] The invention belongs to the technical field of landscape decorative lamp control, in particular to a landscape decorative lamp system and an address coding and display control method thereof. Background technique [0002] At present, the existing landscape decorative light system includes multiple decorative lights, and each decorative light contains multiple pixel points, and each pixel point is composed of red, green, and blue LEDs or single-color LEDs. The decorative lights adopt a serial method to transmit display data one by one from the first decorative light to achieve the purpose of driving each decorative light for display. In the process of transmitting display data, the driver chip in each decorative light The received display data is enlarged and then sent to the next decorative lamp. However, in the process of transmitting the display data, if the driver chip of a certain decorative light in the landscape decorative light system fails, t...
