A single-lamp energy-saving control system and control method based on soft-switching multi-level voltage regulation

Abstract

The invention discloses a single-lamp energy-saving control system and control method based on soft hand-off and multi-shift voltage regulation. The control system comprises a microprocessor, wherein the microprocessor is in communication with a self-coupling voltage reduction module and is further in communicated with an intelligent concentrator through a power line carrier communication module, the microprocessor is used for acquiring running data of a streetlamp and transmitting the running data to the intelligent concentrator, the running data is uploaded into a master station server by the intelligent concentrator, and the microprocessor detects a running state of a self-coupling transformer through the self-coupling voltage reduction module, and receives a control instruction of the intelligent concentrator to carry out soft hand-off on the self-coupling transformer so as to achieve control on a switch lamp and control on multi-shift stable voltage regulation. With the adoption of a soft hand-off technology, the switching reliability can be effectively improved, uninterruptable voltage output is ensured, and a phenomenon that a high-voltage sodium lamp is turned off caused by instant voltage drop is avoided.

Description

technical field [0001] The invention relates to single-lamp control technology, in particular to a single-lamp energy-saving control system and control method based on soft-switching multi-level voltage regulation. Background technique [0002] With the development of social urbanization, the number of lighting street lamps continues to rise, and its power consumption increases accordingly. How to use road lighting rationally has attracted people's attention day by day. Street lighting is to provide brightness for pedestrians and vehicles on the road. In the second half of the night, due to the large decrease in road traffic flow, the demand for illumination decreases, and this period is the low period of electricity consumption, and the power supply voltage is higher than other periods. A relatively large increase will lead to an increase in power consumption and a reduction in the life of the lamp. Therefore, there is a large amount of waste of electric energy in the way...

Problems solved by technology

However, hard switching is used when switching between different gears, directly jumping from one gear to another, the moment of switching will cause a voltage drop, and the phenomenon of turning off the lights is more prominent

Moreover, there is a lack of monitoring of the operating status of the transformer, and the phenomenon of heating and burning equipment due to the overload of the autotransformer occurs from time to time, and there are certain potential safety hazards
