Design and Application of Street Lamp Supervision Control System on LonWorks

According to the characteristic of high pressure sodium lamp,the voltage adjustment method by inductances in series is proposed.And with the LonWorks power line carrier technology,a kind of street lamp supervision control device is developed on PL3120/PL3150 neuron chips,which has many advantages such as no harmful effects on power system and street lamps,easy installation,no additional communication lines.The test and calculation values of energy-saving quantity are roughly the same.Furthermore,a street lamp supervision control system which owns running schedule,remote operation,real-time monitoring and failure alarm is also developed on this basis of device.Now the device and system have already run for a long time with significant energy saving effect.
