Patent of invention " environment-friendly type intelligent road lamp current-reducing energy-saving control apparatus and method " (application number: 200610025458.8), adopt many taps to fall power ballast realization and fall Current Control.
Above-mentioned energy-saving controlling device for street lamp and method comprise wireless communication technique mostly, extension frequency carrier mechanics of communication, and power energy-saving falls in Long-distance Control street lamp timing open and close, the single lamp of timing.There is following problem:
1, electric line carrier communication needs street lamp power supply, road lamp power supply industrial siding, be difficult to realize, and interference free performance is lower in most cities, and system reliability is poor.The communication distance of existing power carrier communication only has tens meters, and the highest also only have hundreds of rice.
2, the unlatching of timesharing to single lamp, close, timesharing falls merit and adopts multiple switch cubicles are set, stepping step-down adopts electromagnetic mode, although reached certain power savings, consumes material and greatly still has the energy and environmental problem.
3, the method that adopts DALI standard agreement to realize master-slave mode Long-distance Control exists operating distance near, thereby from the few little shortcoming of system control capacity that causes of node.
4, fixing step-down mode power saving rate is low, easily causes voltage instability simultaneously, has a strong impact on street lamp useful life.
5, system or equipment mostly lacks self-protection function, or defencive function is incomplete.
6, lack meteorological interlock, cable anti-theft alarm, the functions such as dynamic electronic map demonstration, control function singleness, are difficult to adapt to the demand that modern city street lamp is built.
