Abstract

The utility model is suitable for the technology field and provides a street lamp energy saving system. The system is provided with a temperature transformer, a current transformer, a voltage transformer, an electric energy metering unit, an analysis circuit, a single chip microcomputer, a control circuit and a GPRS unit. The temperature transformer, the current transformer and the voltage transformer collect corresponding electric energy parameters respectively. After the obtained electric energy parameters are input to the single chip microcomputer, the single chip microcomputer determines a working state of the street lamp according to a predetermined parameter value and displays a working state parameter in real time. When faults of overloading, an open phase, an imbalance under voltage, an overvoltage, overtemperature and the like are generated, the single chip microcomputer is controlled to output corresponding control and an indication signal according to a fault diagnosis rule so as to realize power adjustment and other motion of the street lamp. Simultaneously, motion information is transmitted to a far-end monitoring center and an alarm signal is emitted. Therefore, a street lamp illumination system is optimized. The structure is simple. Reliability is strong and power consumption of the street lamp is effectively saved.

Description

A kind of road lamp energy-saving system

Technical field

The utility model relates to the energy-conserving control technology field, relates in particular to a kind of road lamp energy-saving system.

Background technology

At present, the city street lamp illuminator generally adopts the light fixtures such as high-pressure sodium lamp, mercury lamp, Metal halogen lamp, it is strict to supply power voltage, power consumption is large, at city lighting, beautify under the trend of spring tide, street lamp quantity increase the continuous increase that can cause power consumption, our electric power resource is being engulfed in the city illumination power consumption, causes the supply of electric power and the contradiction between the consumption more and more outstanding.

At present, the road lamp system street lamp in most of city all adopts the mode of " at full capacity " to throw light on, the traditional approachs such as that control mode remains is simply light-operated, time control or manual regulation and control, this class lighting system ubiquity is not enough, for example the vehicle on the road and pedestrian become rare after the midnight, the mode of employing " at full capacity " certainly will cause the waste of power supply, runs counter to the national policy of building " energy conservation type society ".

The utility model content

The purpose of this utility model is to provide a kind of energy-saving device for road lamp, and the road lamp system street lamp that being intended to solve prior art provides all adopts the mode of " at full capacity " to throw light on, and has the problem of more defective.

The utility model is achieved in that a kind of road lamp energy-saving system, and described road lamp energy-saving system is installed on each street lamp, and described road lamp energy-saving system comprises:

Current transformer;

The temperature instrument transformer;

Voltage transformer;

The electric energy metrical unit;

The analysis circuit that is connected with described current transformer, voltage transformer and electric energy metrical unit;

The single-chip microcomputer that is connected with described analysis circuit;

The pressure regulation unit that is connected with described single-chip microcomputer;

The GPRS unit that is connected with described single-chip microcomputer;

The power supply and the clock circuit that are connected with described single-chip microcomputer;

The illuminance collecting unit that is connected with described single-chip microcomputer;

The touch display screen that is connected with described single-chip microcomputer.

The road lamp energy-saving system that the utility model provides is provided with temperature instrument transformer, current transformer, voltage transformer, electric energy metrical unit, analysis circuit, single-chip microcomputer, control circuit and GPRS unit, temperature instrument transformer, current transformer and voltage transformer gather corresponding electrical energy parameter respectively, after the electrical energy parameter that collects outputs to single-chip microcomputer, single-chip microcomputer is judged the operating state of street lamp according to the predefined parameter value, simultaneously working status parameter is shown in real time; When transship, during the fault such as phase shortage, unbalanced under voltage, overvoltage, excess Temperature, control single chip computer is realized the actions such as power adjustments of street lamp according to the corresponding control of fault judgment rule output and index signal; Simultaneously, this action message is sent to the Surveillance center of far-end and sends alarm signal, thereby optimized street lamp illumination system, simple in structure, reliability is strong, has effectively saved the street lamp electricity consumption.
