Each intelligent controller in Fig. 1 controls 26 street lamps or 26 street lamp circuits respectively. The number of intelligent controllers in the system is determined by the PC. The system mainly has the following functions: remote control function, telemetry function, remote signaling function and alarm function. the

Remote control function: store control-related parameters such as manually defined scene tables, scheme tables, scheduling tables, primary and secondary circuit configuration tables, detection circuit configuration tables, and illumination mode tables in the PC, and download them to the intelligent controller As the basis for this part of the control strategy. If there are no special circumstances, the intelligent controller first compares and analyzes the data collected by the illuminance detection unit and the data set in the illuminance mode table, and can determine the brightness of the five modes: sunny, cloudy, cloudy, heavy cloudy, and evening. A sort of. The first four modes correspond directly to their scenarios. However, for the evening mode, the controller also needs to obtain the plan to be executed in the evening according to the scene table, plan table and schedule table, and automatically execute the corresponding street light switch scene action according to the time.
