4. Project income 4.1 Save electricityReasonable switching light control power saving: When the original clock control mode is running, it is necessary to periodically adjust the time setting of the clock control device. Due to manpower, the adjustment cycle cannot be too short, generally 1-2 times per month. In this way, you need to set aside about 15 minutes for each adjustment, that is, 15 minutes ahead of time, and 15 minutes later for a total of about 30 minutes. In this way, the lights are turned on for an average of 30 minutes each day during each adjustment cycle.
Elimination of abnormal lighting during the day to save electricity: According to the experience data of the street lighting industry, an average month requires a lot of manpower and resources to troubleshoot irregular lighting during the day, each year can reduce the amount of considerable expenditure.
Improve the life of grid equipment and lamps: traditional street lamp management (manual or clock-controlled) requires the lights to be fully on, and all lights must be turned off, which has a great impact on the grid load and the lamp. After the system is adopted, it can significantly reduce the power grid. And the impact of lamps can make the lamp's useful life extend.
Remote metering and copying automatic metering: traditional electricity metering is done by manually driving a meter to the site, which is inefficient and costly. After adopting this system, it can monitor the electricity consumption in a certain period of time and in a certain area, which not only saves manpower and material resources, but also can aggregate and report the electricity situation in a timely manner, reducing costs and greatly improving work efficiency.
To maximize the savings in cable and wire and labor costs: The system can maximize the savings of cables and wires, can greatly reduce construction costs and shorten the construction period, it will not affect road traffic, and social effects can be imagined.
Humanized services: Due to the versatility of the system, various lighting control methods can be implemented. According to the different needs of each city, we can maximize safety lighting, user-friendly lighting and intelligent lighting.
4.2 Social BenefitsTo enhance the urban brand image: The urban landscape lighting system is not only a public welfare undertaking but also an urban image project.

The climate is mild and humid with four distinct seasons. Wenling ranks 14th among the top 100 counties and cities in the country in the eighth national basic competitiveness of county economy. The comprehensive strength of medium and small cities ranks the 32nd in the country. In 2008, the city's industrial added value was 23.344 billion yuan, of which the industrial output value was 63.553 billion yuan. The industrial economy has formed six pillar industries of motorcycles and automobile and motorcycle accessories, pumps and motors, shoes and hats leather and plastics, household cookers and metal products, shipbuilding, construction and building materials. There are a total of 1,725 ​​large-scale enterprises, 119 enterprises with an annual output value exceeding 100 million yuan, of which 7-50 million yuan are enterprises and 6 are over 1 billion yuan. Became the "China's Small Pump Industry City," "China's Small Air Compressor Capital," "China Hat Industry City," "China Pump Export Base," "China Air Compressor Export Base," and "China's Small Motor Export Base." "China Footwear Export Base" and "National Quality Inspection Base for Motor Exports".
Background of the project
Wenling City Urban Construction Bureau as the competent authority of urban quantification projects has been carefully planning urban lighting projects for a few years. It has invested 3.2 million to create urban living room lighting and enhance the city's image; investment 600 has created the main entrance to the city to improve lighting and improve the business climate; To optimize the lighting around Donghuige, highlight the beauty of architecture, the beauty of roads, and the beauty of greenery. While renovating incomplete and low-grade rough lighting facilities, the company also digs deeper into cultural connotations, improves the artistic effects of nightscape lighting, displays urban brands through lighting design, and promotes urban culture. Further expand the urban lighting project scale. Lighting facilities have been installed in some public buildings, commercial facilities, and high-rise residential buildings at the main entrance to the city, highlighting the construction of lighting facilities for key road sections, window industries, and key buildings, and urging relevant units to install lighting facilities as soon as possible to ensure that the center is fully completed as planned. Urban night lights construction task. Use scientific management methods to implement multi-level lighting management for each quantitative project. The Wenling Municipal Government regards Lianghua Project as a people-oriented project and a livelihood project. With the vigorous promotion of the relevant departments such as the Construction Bureau, the extension of the role of city night lighting project has gradually expanded. While illuminating the journey for the citizens, along with the development of society, the night-lighting project has become a new business card for the city. The overall project of Wenling City Lighting is not a lighting and beautification project in the general sense, and it is not an image project; instead, the development of modern cities has entered a relatively mature stage, and the geographical and natural culture, industrial culture, and social folk culture of the city The comprehensive refinement makes this city a unique, exclusive, exclusive city image and city label. This is a truly comprehensive cultural project.
It is well known that Zhejiang is a region with very tight electric power resources. With the development of urban construction, the number of road lighting and landscape lighting is increasing, and the Construction Bureau puts forward high requirements for the management of landscape lighting. The Construction Bureau hopes to use modern technology to realize It can fully demonstrate the tremendous progress of Wenling's urban modernization construction and can rationally economize on the dual goals of using electric power resources. The original control method for all lighting projects in Wenling City is based on decentralized time control, that is, a time controller is installed in the control box at the site, and the time switch light is realized by presetting the switch time. Due to the current energy saving pressure, all lighting lights are not on weekdays. When encountering such tasks as the head of reception, welcoming the guests of the country, and organizing large-scale events, the relevant person in charge of the Construction Bureau shall inform the landscape light units in advance to perform the task of switching lights manually. It is often the case that time is very tight, the telephone notification can not be issued in time to the task, resulting in switching light task can not be completed in a timely manner. Based on the above circumstances, it is imperative to establish a centralized and unified lighting control center.
In order to achieve centralized lighting centralized control management and increase lighting protection, in 2008 the Wenling Construction Bureau invested in the construction of a GPRS wireless landscape lighting centralized control system. The system uses advanced GPRS wireless communication and embedded intelligent control technology to make lighting control, security and security, and equipment monitoring become a whole. After the monitoring system was implemented, the Construction Bureau implemented centralized lighting control of the city's lighting. When the task of a switch lamp needs to be released, it is no longer necessary to notify the property units one by one as in the past. Instead, it is only necessary at the control center to send the time scheme of the switch lamp to each monitoring device through the computer. Can achieve on-off control of landscape lighting.

Improve the city image: After the system is used, the on/off of the landscape light in the whole area can be automatically controlled. At the same time, because the city lighting monitoring system has automatic alarm, patrol measurement, and selective measurement functions, at the same time, the maintenance personnel can combine the display interface to understand the location and status of the fault in a matter of seconds after the fault occurs, providing a powerful guarantee for timely repair. . The timely maintenance of the landscape light can greatly reduce the complaints to the lighting management department and further enhance the image of the city.
Reduce maintenance costs: The system will change the traditional "seeing lights to find faults" to "duty to wait for the police," not only reduces the "touring lights" personnel and vehicle losses, reducing maintenance costs; but before the maintenance of the vehicle has been aware of the fault The exact location and basic status of the equipment thus shortens the maintenance time and improves the efficiency of inspections; this will result in great economic benefits.
Energy conservation: The current time scheme control method realizes the opening or closing of the landscape light within a preset time zone; this kind of on-demand lighting measures not only meets the public's demand for urban landscape lighting, but also avoids the landscape light. The unnecessary opening of the lighting system reduces the turn-on time and thus saves a great deal of electrical energy. Through the improvement of the lighting circuit, the use of the landscape light in the non-holiday lights will only save a large part of the landscape light. The policy of a conservation-minded society has practical significance.
