1. Project Analysis

Street lamp project is mainly to achieve the goal of single lamp control. The main advantages of single lamp control are secondary energy saving, control of each lamp, subregional control and time-sharing control. Single lamp control can make the management of street lamp lighting more convenient and flexible.

2. Equipment Composition

Street lamp intelligent lighting control system is mainly composed of HM-SC2000A1, centralized controller, PLC single lamp controller, LED street lamp and so on.

3. Main Functions of the System

1) Implementing multiple control modes

Manual mode and automatic mode (time-sharing control and zoning control) can automatically turn on and adjust luminaire brightness according to user's needs under any circumstances.

2) Various monitoring methods

Managers can control the opening, closing, dimming and power, voltage, current, power factor and state inquiry of any single lamp in each segment through remote, real-time and preset modes, so as to know the running state of the lamp in real time. It can remotely monitor the lighting rate, energy saving rate and the operation of lighting equipment.

3) Active reporting of lamp faults

When the lamp fails in use, the concentrator can report the lamp failures to the administrator user, and provide the reasons for the lamp failures and the specific location information of the street lamp.

4) Data query

The realization of remote, intelligent and real-time meter reading, real-time and fast data query functions (including lighting rate, lamp parameters, power consumption, maintenance records) can ensure the timeliness and effectiveness of data.

5) Safety management

It has user privilege settings to prevent non-managers from using and ensure the reliability of system control security.

6) Map Guidance

It can intuitively reflect the specific location of street lamp, fault situation and lighting information.

4. System Characteristics

The energy-saving scheme of the system can be changed freely and has high flexibility.

Redundant design, each system module can work independently. (that is, when the communication between the concentrator and the main station fails, the concentrator can work independently to ensure the lighting requirements)

The system has the function of automatic reporting lamp failures and judging the causes of lamp failures, which greatly reduces the investment of routine inspection and maintenance costs.

Adding intelligent control system can realize secondary energy saving on the basis of original lighting energy saving and achieve energy saving effect of 30% - 40%.

5. Scope of application of this system

Intelligent street lighting system is automatically managed and maintained by computer system software. All control operations are automatically completed by the system, and the lighting requirements of street lamps can be completed without manual intervention.

After the completion of the system, the management center can realize remote control and intelligent endless dimming of each street lamp on the road, that is, combining light control, and adjusting brightness according to day and night alternation, to achieve time-division and regional adjustment. Realize on-demand lighting in a real sense. The system can be applied not only to street lamps, but also to sports fields, shopping malls, schools, families and other places where lamps are used more. The management is more convenient and the effect of energy saving is better.
