Description

technical field [0001] The invention relates to the technical field of lighting control, in particular to a linkage control system for stage lighting and landscape lighting. Background technique [0002] With the continuous development of stage lighting and landscape lighting technology at home and abroad, and the diversification of various requirements for lighting effects, the existing DMX512 communication protocol LED lighting control system cannot flexibly adapt to various forms; so far, lighting control The existing technology of the system generally adopts the DMX512 stage lighting communication protocol standard proposed by the United States Institute for Theater Technology (Inc) in August 1986, DMX 512 (DMX=Digital Multiplex) protocol, because the DMX512 communication protocol belongs to A simple stage lighting control protocol, which can be easily transplanted and applied in landscape lighting projects without investing too much research and development time, so it ...

AI Technical Summary

Problems solved by technology

[0003] 1. The communication baud rate of the DMX512 protocol is 250K bps, the baud rate is relatively high, and cannot be changed, so it is not suitable for long-distance transmission, such as bridges, gardens, and various scattered layout lighting environments with long control signal distances. The interference ability is poor, and the transmission distance is generally only about 100 meters, which is not suitable for long-distance complex architectural patterns and landscape lighting environments

[0004] 2. DMX512 protocol address, each controller output port is limited to only 512 channels, so the number of each frame sent is limited, the structure of the control host, signal distributor, and lighting system is complex, the engineering construction is difficult, and the system is reliable for long-term operation Poor performance and high maintenance costs, especially in long-distance complex landscape lighting projects, often cause the scene display effect to be out of control

[0005] 3. Since the DMX512 control system belongs to the dual network control structure, the upper layer is the Ethernet communication network, and the bottom layer is the RS485 communication network, which is used in landscape lighting projects. Since the upper layer Ethernet communication requires RJ45 crystal head connection, especially in humid and coastal environments Under the circumstances, a large number of RJ45 crystal plugs are used to connect; it is easy to cause poor contact due to ambient air corrosion, making the communication signal unstable, and the long-term operation reliability of the control system is poor.

[0006] 4. The DMX512 control system belongs to the dynamic dimming method, which sends signals by frequent scanning. Even if the signal is unstable for only 0.1 seconds, it will cause the display effect in the overall landscape lighting project to jitter.

[0007] 5. The DMX512 protocol has 512 channels in each frame, and each channel corresponds to a single-color lamp address. For red, green, and blue LED lamps, it will occupy 3 channel addresses, so each frame of 512 channels only contains 170 red , green, blue 3-color LED lamps, and each frame of 512 channels must be equipped with a signal distributor device, resulting in complex system address structure, engineering construction and maintenance are more difficult
