Lighting control system

Abstract

The invention provides a lighting control system, which comprises a plurality of wireless network subsystems with different communication systems, wherein each wireless network subsystem comprises a plurality of communication nodes, and the wireless network subsystems are in communication connection through at least two communication nodes with multiple systems, wherein after each communication node of each wireless network subsystem receives a lighting control message, if the communication node judges that a target address in the lighting control message is not the local communication node, the communication node broadcasts the lighting control message to the wireless network subsystem where the communication node is located; and after each communication node with the multiple systems receives the lighting control message, if the communication node with the multiple systems judges that the target address in the lighting control message is not the local communication node, the communication node with the multiple systems broadcasts the lighting control message to different wireless network subsystems respectively. Through the broadcast of each communication node and the broadcast of the nodes with multiple systems in different system networks, a communication multi-plane and multi-link redundant means is provided to guarantee reliable communication, and the reliable transmission of control information in the lighting control system is guaranteed.

Description

technical field [0001] The invention relates to a control system, especially an illumination control system. Background technique [0002] With the rapid development of the Internet of Things, smart products have sprung up like mushrooms after rain, and the number of network nodes has increased unprecedentedly. As a local communication technology for local environments, wireless communication has become one of the mainstream choices in lighting control systems. However, compared with wired communication technology, wireless is affected by signal interference, signal strength, environmental factors (such as partition walls, etc.) and its communication quality is compromised, thus limiting its application range. The market needs a reliable wireless communication technology. Method of lighting control system.

Problems solved by technology

However, compared with wired communication technology, wireless is affected by signal interference, signal strength, environmental factors (such as partition walls, etc.) and its communication quality is compromised, thereby limiting its application range. The market needs a reliable wireless communication technology. method of lighting control system

[0003] A lighting control system with a single standard, such as a lighting control system composed of Wifi, Zigbee, Zwave, BLE, non-standard 2.4G and other networks, has its own communication limitations, such as distance, frequency conflict, poor wall penetration, etc. , resulting in a single standard network is often unstable, or can not be generally applicable to a variety of occasions

[0004] In addition, single-standard control systems often have applicability problems, such as high Wi-Fi costs and high power consumption, which are not suitable for operation panels or occasions where the number of router nodes is limited

[0005] Therefore, the wireless network must always be a network of mixed standards, but how to make a network of mixed standards into a complete and unified network often requires intercommunication through their own additional gateway devices, resulting in waste of cost and occupation of space. incomprehensible
