Wireless remote street lamp lighting centralized control system

The centralized control system of wireless remote street lighting is a new generation of urban road lighting management system introduced by our company. The system adopts advanced intelligent control technology, wireless communication technology, GIS technology, remote video technology, large screen technology and so on. , and can remotely switch on and off the city's street lamps, and can also judge whether the street lamp power distribution equipment fails according to the analysis of measured data, and estimate and calculate the lighting rate of street lamps. Alarm processing for abnormal conditions such as line phase loss, loop grounding, daytime lighting, night light-off, large-scale light-off, etc., plays a positive role in ensuring night traffic, public safety and beautifying city night scenes.

Application scenario analysis

Centralized control project of street lamps in Gaobeidian city

In 20 10, Gaobeidian city reformed the street lamps of urban 12 main and secondary roads and 33 small streets and alleys, and realized the centralized control of wireless remote street lamp lighting. The reformed road lighting system will use modern computer technology, communication technology and automatic control technology to implement networked, information-based, intelligent and automatic centralized remote control, centralized and unified management, remote diagnosis and maintenance and automatic fault alarm for all lighting equipment and facilities, effectively improve the control, maintenance and overhaul ability and efficiency of the lighting system, and further ensure the overall "lighting rate" and "equipment integrity rate"; At the same time, reducing power consumption and labor intensity and avoiding unnecessary waste of electricity, manpower and material resources will help to further improve the quality of road lighting, thus improving the management and service level of the whole city.

Wireless remote lighting centralized control system

The centralized control system of wireless remote lighting is a distributed "three remote" system composed of advanced GPRS/CDMA wireless communication network, computer information management and intelligent lighting controller. The system can remotely switch the citywide landscape lights, send signals to inform the working state of the equipment, remotely measure the current, voltage and power consumption of the lamps, analyze the equipment faults, give an alarm for abnormal situations, and notify relevant managers in time through short messages; The system can set a variety of lighting modes such as working day mode, holiday mode and major holiday mode according to different needs, effectively reducing lighting time; The system has various control modes such as timing control and manual control, which can adjust the on/off time of lights at any time, and can dispatch emergency lights through computers or mobile phones during temporary or unexpected activities.

Application scenario analysis

There are more than 40 single buildings and two landmark buildings in Financial Street, with the height of128m, and its landscape lighting project is the supporting project of Xicheng District Olympic Games. The project involves the construction of lighting facilities such as outline lights, floodlights and spotlights along the financial street. After the implementation of the lighting remote control system, the managers of relevant departments can download the preset time plan for switching on and off the lights to the lighting controller on site through the monitoring computer in the control center, and the controller can automatically control the lights on/off according to the preset time schedule. Changed the management mode of asking all property units to turn on the lights manually when encountering major events or important holidays. This not only reduces the work intensity of the management staff, improves the work efficiency, but also reduces the work mistakes caused by human factors. The lighting controller installed in this project works normally during the Olympic Games, and the central software system runs stably, which has been highly praised by users.

Wireless remote garden lighting centralized control system

With the change of lifestyle of urban residents in recent years, night trips are more and more frequent. In order to meet the needs of night activities and beautify the city night scene, many cities are widely carrying out "lighting projects". Garden lighting, especially the lighting of urban open parks and green spaces, as one of the important components of urban "lighting project", is naturally paid more and more attention by Austrian city managers. The garden at night doesn't want to illuminate everything. The selective use of lighting can make the buildings, sculptures, flowers, trees and rocks in the garden present different flavors from those in the daytime. In the light and shadow created by lighting, the landscape will form a quiet atmosphere.

With the help of Jiafuxin wireless remote garden lighting centralized control system, all functional road lighting facilities and landscape lighting facilities in garden scenic spots can be centrally controlled. The system can control all the lighting lamps in the park in groups, regions and time periods. It can not only ensure that all facilities are opened during important holidays and peak tourist hours, but also fully display the artistic effect created by lighting facilities. It is also possible to turn off the implementation of power-consuming lighting on weekdays or during periods when tourists are scarce, so as to realize power-saving lighting control.

Application scenario analysis

All lighting facilities in Beijing Daxing Niantan Park adopt our company's GF-LCS6008 intelligent lighting controller. Managers can realize centralized control of lighting fixtures in the park through computer monitoring software or smart phone monitoring software in the control center of the park management office. Humanized control and management of lighting facilities through lighting control system can not only make tourists fully enjoy the comfortable environment atmosphere brought by lighting facilities at night, but also turn on only some functional lighting lamps in the latter half of the night, thus ensuring the safety management of the park.

Wireless remote centralized control system for port lighting

The automatic control of port lighting system is mainly to divide the lamps and lanterns on the high pole light towers in the port into arrays, which are used for production lighting and daily street lighting in all directions respectively. The lamps used for different surgical lighting are controlled by the remote control box respectively. The operation of the remote control box is controlled by the computer system installed in the production control center of the wharf. In this way, the automatic control technology is applied to the port lighting system, and the production lighting of the whole port is placed under the centralized control of the production dispatcher, and the lighting switch is controlled remotely by the management personnel. This can not only effectively improve the utilization rate of equipment, prolong the service life, but also save human resources and production costs, which has good economic and social benefits.

Application scenario analysis

Longkou Port Group Co., Ltd. fundamentally solved the problem of frequent manual operation of pole lamp switch in the past, and met the requirements of energy saving and consumption reduction to the maximum extent. It put forward the transformation requirements of pole lamp control system and adopted Jiafuxin wireless remote port lighting centralized control system. The system has many control modes, such as timing control and manual control, which can realize the automatic on-off control of high-pole lights in the port area and the control of different lighting modes under different operation requirements. Using this system, the staff can flexibly set the time and mode of turning on and off the lights, grasp the running state of lighting equipment in real time, and find the faults of lighting equipment in time, thus ensuring the safety and efficiency of port night operation.
