Survey and analysis of total cost of outdoor lighting projects

With the recent domestic epidemic under effective control, the economy finally pressed the restart button. Many provinces, cities, and regions have launched cultural tourism night tourism projects, investing billions, tens of billions, or even hundreds of billions to stimulate the economic recovery and growth of night cultural tourism. In the current period when domestic and foreign demand is relatively weak, how to take into account the long-term development of the enterprise and achieve the best economic benefits has become one of the urgent demands of the company.

Survey and analysis of total cost of outdoor lighting projects

Is your “cost control” right?

The so-called total cost of ownership (TCO) refers to the sum of equipment purchase costs and the costs incurred during the entire life service cycle, including after-sales operation and maintenance costs. This survey found that companies pay more attention to TCO than just purchase costs.

In outdoor lighting construction projects, TCO is mainly composed of three parts: lamp cost, construction cost, and maintenance cost. Among them, the maintenance cost accounts for 8%-15%, while the lighting cost accounts for 55%-60%, and the construction cost is 25%-30%.

All interviewees agreed that TCO played an important role in the project. Among them, more than 45% believe that TCO is more important. After all, the project is the overall cost of procurement + installation + maintenance, while 43% believe that TCO is very important because money is spent on the blade. Although 11.39% of people think that the overall effect of the project is more important, they also said that the importance of TCO in the project cannot be ignored.

It can be seen that in the minds of lighting practitioners, especially owners, lighting designers, and engineers, TCO is the first restrictive element in starting a project. From the beginning of the construction phase, cost optimization should be considered as a whole, not only the equipment itself but also the operation and maintenance costs that may occur during the entire project operation cycle.

Redefine the “cost economy” of outdoor lighting

There is no doubt that the purchase cost of lamps directly affects the level of cost control in all aspects, and nearly 80% of the lamp’s own manufacturing costs have been determined by the raw materials at the beginning of the lamp design. What kind of light source, heat dissipation, waterproof and dustproof to choose? As raw materials, breathable valves have a direct impact on the cost of the lamp, and also affect the maintenance cost of 8% to 15% in the later period.

For the companies surveyed this time, their cost reduction mainly starts from project management costs, business costs, lighting costs, construction costs, and maintenance costs. Among them, 72.15% and 60.76% believe that project management costs can be reduced. And business costs for cost control; 50.63% and 48.1% of the interviewees think it can be optimized from the cost of lighting and maintenance.

Lamp cost and maintenance cost complement each other. Although low-quality products have low procurement costs, their subsequent maintenance costs will continue to increase sharply, which will still lead to a sharp increase in TCO. Therefore, in project procurement, in addition to considering the cost of the lamp itself, it should also consider its technical properties such as waterproof level, breathability, oil pollution, and salt spray, so as to effectively reduce the operation and maintenance risks and achieve the optimal cost configuration. Improve economic efficiency as a whole.

In addition, some people in the lighting industry said that they can also reduce unnecessary costs by reducing transportation costs for foreign-related projects, introducing smart management, and strengthening technology upgrades.

Conclusion

It can be seen that the total cost of ownership (TCO) control has penetrated into all aspects of outdoor lighting project operation, ranging from mid-term construction and later maintenance to the early purchase of lighting materials. Reasonable lighting costs, balanced technical construction, and good post-maintenance all provide unlimited possibilities for the optimization of the total cost of project ownership.

Site resources required for deep coverage. At the same time, a unified management platform for smart light poles will be built, and a number of smart city applications such as smart lighting, smart transportation, and smart policy will be put on poles.

Smart light pole is a new type of information infrastructure that integrates lighting, video surveillance, traffic management, environmental monitoring, communication, and other functions. It consists of infrastructure and poles, lighting facilities, traffic, video surveillance, and other pole-mounted facilities. An important carrier of the new smart city. In order to seize opportunities for the development of new infrastructure and smart cities such as 5G, promote the in-depth integration of a new generation of information and communication technologies and the construction of new smart cities, and strengthen Guangzhou’s leading position in the development of emerging industries such as 5G, the Internet of Things, artificial intelligence, and the Internet of Vehicles. Expand the scope of pilot work for the promotion of smart light poles and formulate this plan.

As a new generation of urban information infrastructure, smart light poles are related to many areas in the “new infrastructure”, such as 5G base stations, new energy vehicle charging piles, and Internet of Vehicles. As an important part and an important entrance of a smart city, smart light poles are a natural carrying platform for the informatization construction of smart cities.

The “Plan” proposes that Guangzhou should accelerate the pilot promotion of smart light poles in the city’s main arterial roads and important places. Mainly to meet the future 5G evolution, the booming development of the Internet of Things, big data, artificial intelligence, driverless, cloud computing, virtual reality, etc., as well as the needs of high-performance cities, and to promote the overall construction and planning of the city.

Simultaneously promote the upgrading and transformation of old light poles.

According to the plan, the total planned construction of smart light poles in Guangzhou in 2020 will be 4,238, covering 842 roads, with a radiation area of 3242.89 square kilometers. The construction area is selected from the busy areas of various districts, the core business district is planned, and the scope covers the road sections where operators need to mount the micro base station, and the demonstration pilot promotion projects of smart light poles in 11 districts of Guangzhou. Among them, the number of smart light poles planned in Yuexiu District is 704, which is the largest among all districts. Haizhu District is followed by 614 smart light poles.

As a frontier city in my country’s economic development and reform and opening up, Guangzhou has taken the lead in the construction of smart light poles in the country. At present, it has issued a number of policies, special plans, and standards to support and standardize the construction of smart light poles in the city.

MIT’s autonomous robot uses UV-C to kill the new coronavirus on the surface

Researchers from the Massachusetts Institute of Technology (MIT) have created a new robot to help fight the new coronavirus. This autonomous machine emits UV-C, which can kill microorganisms and damage their DNA. The robot is a joint project of the Massachusetts Institute of Technology Computer Science and Artificial Intelligence Laboratory (CSAIL) and Ava Robotics.

MIT's autonomous robot uses UV-C to kill the new coronavirus on the surface

A prototype machine has been deployed in the Greater Boston Food Bank (GBFB), and its speed of 0.22 miles per hour should allow it to cover an area of 4,000 square feet in 30 minutes. The ultraviolet rays emitted by the four vertical bars can neutralize about 90% of the new coronavirus particles on the surface.

During the Covid-19 crisis, food banks are more important than ever, because many people lost their jobs due to the epidemic. Keeping facilities free from virus infection is essential to ensure that the virus does not spread further. “Food banks provide important services to our communities, so it is crucial to help keep these businesses running,” said Alyssa Pierson, a research scientist at CSAIL. “Here, there is a unique opportunity to provide additional disinfection power to their current workflow and help reduce the risk of exposure to Covid-19.”

The robot was initially operated by a remote user, and the user taught it its path around the warehouse. Then it can operate autonomously and move between user-defined waypoints, which can be added or deleted as needed. The machine is used to disinfect the premises after workers leave work.

Ultraviolet sterilization is often used in hospitals and other medical environments to disinfect empty patient waiting rooms. The researchers hope that the robot will eventually find use in other environments, including factories, restaurants, and shops.

“We are very happy to see UV disinfection robots supporting our community at this time of need,” said Daniela Rus, director of CSAIL and project leader. “The insights we gained from GBFB’s work highlight several algorithmic challenges. We plan to address these issues to expand the scope of autonomous UV disinfection in complex spaces, including dormitories, schools, airplanes, and supermarkets.”

Pakistan’s textile exports accelerate

Pakistan’s largest textile exporter reported that after the EU and the United States lifted the blockade, the country resumed and received new orders, mainly for socks and other products, but its denim part has not yet shaken off the pressure brought by the new crown pneumonia.Pakistan's textile exports accelerate

 

It is understood that the socks sector in Pakistan is currently operating at a utilization level of more than 100%, while the denim department is only operating at a utilization level of 50%.

Interloop is a listed company on the Pakistan Stock Exchange, producing products for well-known brands such as Adidas and Nike. The company’s denim department was severely affected by the new crown pneumonia epidemic and lost more than half of its orders. On the other hand, according to the brokerage company, the socks department lost 15% of its orders, so the impact was minimal.

The main export income of Interloop comes from the European Union (60%), and the rest mainly comes from the United States. The textile sector is Pakistan’s largest export earner. According to statistics from the Pakistan Bureau of Statistics, in the 2019-20 fiscal year, the country’s share of total exports (US$21.39 billion) was approximately 60% (US$12.53 billion).

Due to the decline in international demand due to the new crown pneumonia, Pakistan’s exports are facing contraction. However, after the gradual recovery of the EU and US economies, exports began to rebound. Pakistan’s textile exports have fallen by 6% this year. The previous year (Fiscal Year 19) was 13.33 billion U.S. dollars. This year, almost all textile sectors reported a decline in exports. According to statistics from the Pakistani Bureau of Statistics, there was a glimmer of hope in June that textile exports in the past June have rebounded from the same period last year.

An export group said that importers are transferring their textile orders from China to the South Asian market, which provides a good opportunity for Chinese exporters. At present, the price of the group’s export products has not been affected, and so far the benefits of the depreciation of the rupee have not been passed on to importers. However, buyers are asking for the same. In addition to the depreciation of the rupee, the increase in sales, and the decrease in yarn prices are also likely to keep profits rising.

The report quoted the company’s chief financial officer as saying that the company has received orders from three new customers for the socks department and is also working hard to attract new customers to its denim market. One of the good brands is very attractive. Price orders. It is said that ILP’s denim business is currently at a loss, but profits are expected to turn from negative to positive from next year.

Interloop is one of the largest knitwear manufacturers in the world and the sixth-largest export company in Pakistan. The company has two manufacturing units in Pakistan and Bangladesh, a subsidiary in Sri Lanka, and services in the United States, the Netherlands, China, and Japan. 700 million pairs of socks are produced annually, accounting for more than 90% of the total revenue.

Intelligent lighting control technology in building automatic control system

Among the intelligent lighting control systems, electronic induction technology occupies a very important position. Through the combination of electromagnetic voltage regulation and electronic induction technology, the corresponding unified system is used as the basic platform for operation. The actual power supply, power consumption, current, voltage is tracked, controlled, and regulated to ensure that the residents are provided with safer and more convenient power supply and service. Through the analysis of the current intelligent lighting system used in my country’s construction industry, it can be divided into two categories: the first category, a grid of two-line intelligent lighting control system; the second category, line lighting control system. The first type of system can realize the automatic control of the lighting conditions through the cooperation of various systems. It can create a more comfortable lighting environment for the residents according to the actual needs of the residents. It can also protect the lamps and extend the lamps by controlling the voltage and current.

Intelligent lighting control technology in building automatic control system

The main operation mode of the building automation system is integrated control by the central computer, and the various control subsystems cooperate together. It is an automation system with high requirements for comprehensiveness and integrity. In the current building automation system, the main use is sensor technology, and modern communication technology will be used in many control systems. It also adopts a networked control method, and the basic data of the front-end equipment is comprehensively managed by each subsystem. The scientific and perfect building automation system can reasonably allocate heating, ventilation, air conditioning, drainage, power distribution, safety, fire control, and other systems. The main effects of building automation systems on the lives of residents are:

First, the subsystem collects and accesses the actual data to provide a basis for the overall control of the building; second, the integrated processing of the central computer is conducive to the formulation of control strategies for ventilation, air conditioning, power distribution, and security; Thirdly, the information data collected by the automation system can be printed to facilitate the later maintenance and repair work; finally, by analyzing the collected data, the operation trends of each system can be analyzed to ensure the safety of the entire automation system.

Combining the building automation system with the intelligent lighting system can give full play to the value of electric energy, optimize the allocation of electric power resources, save electricity consumption for users, and save electric power resources. The current social integration theory and intelligent control technology are becoming more and more perfect, and the theoretical basis and practical experience are already available, which provides a good foundation for the combination of building automation systems and intelligent lighting control systems.

Building automation systems and intelligent lighting control technology integration methods are diverse, these methods have their own characteristics and have their own unique scope of application. Therefore, which integration method to choose depends on the actual situation of the building and the actual needs of the residents. Scientifically choosing a reasonable integration method can maximize the role of the integrated system. When choosing an integrated system, or when determining whether the integrated system meets our needs, we can consider the following aspects:

First, whether the degree of integration of building an automatic control system and intelligent lighting control technology meets the needs of residents. Different integration methods will show different integration effects in different building structures. If this integration effect can meet the needs of residents and can provide personalized and intelligent services for residents, then this integration method is effective. At the most basic level, there is a cooperative relationship between the building automatic control system and the intelligent lighting control system. Once the system affects the operation of each, then this integration method is not suitable.

Second, whether the building automation system and intelligent lighting control technology integration system are simple. The building’s automatic control system and the intelligent lighting control system are two independent systems during operation. After integration, the local network transmission of each system is smooth, and it will not hinder the wiring work in the design. It is a good integration method. That is to say, when we choose the integration of building automation systems and intelligent lighting control technology, in addition to considering whether the independent operation of each system is smooth, we must also consider the basic wiring work, which is the basis of system control.

Third, the integrated system of building an automatic control system and intelligent lighting control technology has reliability. To achieve integrated control of these systems, it is necessary to ensure that each system uses the same IP address so that comprehensive control of these systems can be achieved, system stability is increased, and errors that may occur are reduced.

Fourth, whether the building automatic control system is compatible with the intelligent lighting control technology integration system. Due to the large number of hardware devices used in the integrated system, it is necessary to consider whether these devices are compatible before selecting devices to prevent system failures due to compatibility issues during actual operation.

Fifth, whether the building automation system and intelligent lighting control technology integration system are operable. The operation method of the integrated system should be as simple as possible to facilitate the operation of the residents and improve the operability of the system. At the same time, the quality of each system must be guaranteed to prevent the value of the system from being reduced due to quality problems.

The smart upgrade of street lamps is an inevitable trend

In the context of the great development of smart city construction, urban public infrastructure is generally moving towards informatization and networking, including smart street lights, as well as products such as the Internet of Things manhole covers and electronic water gauges, which have been launched between cities. The pilot application is expected to be popularized in a large area throughout the country in the future, forming a large-scale urban information collection terminal, helping all functional departments to work in an orderly manner based on data, improving quality and efficiency.

The smart upgrade of street lamps is an inevitable trend

“Multi-in-one” to divide Hezhang’s infrastructure construction investment

The smart street lights installed in Hezhang County adopt intelligent management, starting from the perspective of city beautification, resource integration, energy saving and environmental protection. It integrates digital security subsystem, information release subsystem, and intelligent lighting subsystem, and realizes the integration of social poles such as street light poles, information screen poles, and monitoring poles. Technicians can remotely control all street lights through computers or mobile phones.

The originally built street lamps are traditional lamps such as energy-saving lamps and sodium lamps. The lighting brightness is low, the equipment is aging, the energy consumption is serious, and the maintenance cost and difficulty are relatively high. The new intelligent lighting system of Yibo High-tech uses LED lights and adopts intelligent lighting management methods, which can realize the dimming function of the whole area or accurate to a single lamp, and realize the on-demand lighting of the whole area, reducing energy consumption by 40% . “

European and American markets focus on professional LED lighting

Europe, the United States, Japan and other countries that have paid attention to green energy issues earlier, under the government’s efforts to educate and promote energy conservation policies, most people have a higher willingness to buy LED lamps, so the penetration rate is much higher than the global market. According to statistics, the penetration rate of the domestic LED lighting market in Japan has reached more than 85%, which is one of the fastest countries in the world to promote LED lighting. The Japanese government even further plans to reach the goal of changing all residential lighting to 2020 before the end of 2020. The goal of LED lamps.

European and American markets focus on professional LED lighting

In the US market, according to the 2015 annual survey report released by Osram, about 66% of American households have purchased LED lamps, and most consumers have indicated that they will continue to purchase related products in the future. Therefore, most experts optimistically predict that although the overall sales of LED lamps are still less than half of traditional energy-saving bulbs, the gap between the two has been greatly narrowed, and driven by the decline in LED lamp prices, the overall shipments are expected to exceed in recent years Energy saving light bulb. The introduction of LED lamps by the US state government is also fast. For example, Binghamton, New York, is expected to invest US$4 million to replace 7,000 traditional street lamps with LED street lamps in early 2016 in order to reduce the consumption of natural energy.

Compared with advanced countries, the Southeast Asia market with amazing economic growth is a new market coveted by the LED industry. The Southeast Asian market’s lighting market scale reached US$4.8 billion in 2015, of which LED lighting was around US$1.5 billion. Especially driven by the government’s vigorous promotion of public construction and policy subsidies, the average growth rate in recent years has reached more than 30%, becoming the world’s most developed Potential area. For example, the Indian government plans to purchase as many as 770 million LED bulbs by 2018, replace street lights in 100 cities with LED lamps to reduce 20,000 MW of electrical load and encourage international lighting manufacturers to establish joint ventures with Indian lighting plants Set up a factory, hoping to reduce procurement costs and create more job opportunities.

It is worth noting that after the official establishment of the ASEAN Economic Community, Member States will adopt the same set of electronic equipment inspection standards, that is, electronic products only need to obtain the safety certification issued by a Member State, they can be in the ASEAN Economic The sale in the community has greatly reduced the threshold for international lighting manufacturers to enter the Southeast Asian market, and it is also an excellent opportunity for Taiwanese LED lighting manufacturers to expand their export markets.
