As a semiconductor device, LED makes it possible to digitize and network the light. The light not only provides illumination, but also functions as a management and monitoring function. Ma Wei, director of the Technical Center of the Institute of Light Environment Design, Beijing Tsinghua Tongheng Planning and Design Institute, said that the digital and Internet technology in the field of lighting is mainly to improve the level of lighting control, thus making the maintenance and management of lighting facilities more convenient. Lighting control from the earliest three remote (remote control, remote signaling, telemetry), to the future of the Internet of Things, and now to the cloud control, digital, intelligent and more and more become the dominant lighting. Intelligent lighting has improved the management level. The concept of intelligent lighting has not been long. It generally refers to a control system composed of technologies such as wireless communication, power carrier, intelligence, and information processing. The emergence of intelligent lighting also brings real-time monitoring, regional management, mode management, intelligent early warning, GPS positioning, anti-theft monitoring and other supporting functions. Ma Wei said that intelligent lighting can achieve remote control. For example, you can use your mobile phone to control the lighting at home. If you forget to turn off the lights, you can check it on the mobile phone and control the switch light. Intelligent lighting can also be combined with other controls to play a bigger role. For example, half an hour before going home, you can turn on air conditioners, water heaters, etc. Around the intelligent lighting, you can build a complete smart home system to provide us with a more comfortable life experience. In addition to improving the quality of life of the people in the home field, the management efficiency of smart lighting in the commercial field is even more obvious. Taking road lighting as an example, the previous urban street lamp management must send people out to check whether the lamps are damaged every day. Now with the feedback of the control system, it is very accurate to know which lamp is faulty, which can save manpower and improve maintenance. Management efficiency. Ma Wei revealed that we are preparing the “Regulations for Urban Lighting Energy Conservation Managementâ€. (Beijing) districts and counties need to conduct energy consumption statistics. Intelligent lighting can provide energy consumption reports and improve the management level of functional departments. These smart lights can be rewired without the need for rewiring, which facilitates the integration of new and old lighting control systems. Intelligent lighting makes the design space wider. The emergence of intelligent lighting makes the lighting break through the limitations of lighting. On the other hand, it also provides more possibilities for the innovation of lighting design. The new term of intelligent lighting design has also emerged. . Ma Wei believes that the more important role of intelligent lighting is to make the design space more broad, which can bring greater breakthroughs to urban night lighting. She introduced the lighting design on both sides of Nanchang and Yijiang as an example. Because of the emergence of intelligent lighting, 300 buildings on both sides of the strait could be linked. The lighting system has the difference between the weekday mode, the holiday mode, and the major holiday mode. The weekday mode is to keep still, festivals and major festivals. The LED lighting fixtures on the facade of the building show different scenes under the control of the intelligent control system, such as waterfalls showing local natural scenery, local cultures, and so on. . It is not difficult to see that intelligent lighting makes the design of the program evolve towards the direction of mining urban cultural connotations. Because traditional lighting can only light up buildings, smart lighting can use urban architecture as a vehicle to highlight different themes through lighting. The lighting design on both sides of the Nanchang River is an example of changing the night image of the city through lighting. Nowadays, more and more cities and tourist attractions are aware of the importance of the image of the night city. They all require the design of intelligent lighting combined with the culture of the city. Therefore, intelligent lighting brings a broader space to lighting design. Ma said. However, she also stressed that a successful lighting design must be able to implement, to ensure that the proposed lighting parameters can meet the brightness standards specified in the design; secondly, based on the investment needs of the owners, the most consistent with the nature of the building Design, otherwise the perfect design also deviates from the direction.
Tunneling Face Monitoring System
With the rapid developments in tunnel traffic infrastructure construction, engineers need a portable and real-time system to obtain the tunnel deformation during construction. An automatic and wireless real-time tunnel deformation monitoring system, which is based on laser and machine vision and can give early warnings for tunnel collapse accidents, is proposed. The proposed system uses a fixed laser beam as a monitoring reference. The image acquisition modules mounted on the measured points receive the laser spots and measure the tunnel accumulative deformation and instantaneous deformation velocity. Compensation methods are proposed to reduce measurement errors caused by laser beam feasibility, temperature, air refraction index, and wireless antenna attitude. The feasibility of the system is verified through tunnel tests.
