Central controller for lighting control system with network controllers
A recently granted patent (Publication Number: US11888940B2) discloses a central controller designed for remote communication with multiple network controllers (NC) in a network of communication nodes. The central controller includes a data processing device connected to a communication module, enabling it to receive ID information, position information, and lists of communicable neighboring NCs from each NC. By analyzing this data, the central controller can identify missing or not reporting NCs, determine accurate position information, and detect position drifting NCs within the network. Additionally, the central controller can control the anchor point NC, trigger warnings for missing or drifting NCs, and estimate the location of missing NCs based on neighboring NC data.
Furthermore, the patent describes a lighting control system incorporating the central controller and a network of communication nodes and NCs. Each NC is capable of remote communication with the central controller and near field communication with other NCs. The system allows for the exchange of ID information, position information, and precision information between NCs and the central controller, enabling accurate positioning and monitoring of the network. The NCs are equipped with communication modules and microcontroller units to facilitate data exchange and communication with the central controller, ensuring efficient network management and control. Additionally, a method for identifying missing NCs in the network is outlined, involving the reception of data from each NC, maintenance of lists, crosschecking for missing NCs, and identification of accurate position information and drifting NCs. Each NC plays a crucial role in providing and exchanging data with the central controller to ensure the system's optimal performance and reliability.
