5. ETC lane point light source control system
In November 2022, a set of highway ETC lane point light source control system independently developed by Jiaxing Expressway was put into use at the Jiaxing East Toll Station of Zhejiang Provincial Transportation Group's Shanghai Hangzhou Expressway and achieved good results. The system uses LiDAR as a detection module to achieve the accuracy, timeliness, and stability of early warning signal collection, without being affected by factors such as temperature, dust, and light. This effectively reduces the occurrence rate of ETC lane accidents and improves the on-site safety factor of toll stations.
It is understood that the system mainly consists of three parts: radar detector, control power system, and point light source. Using LiDAR as a detection sensing signal, determine whether there are vehicles passing through the ETC lane. If a vehicle is detected passing by, the radar detector detects the signal and transmits it to the control power system. The control power system starts to supply power, and the point light source lights up, emitting a "red" high-strength LED light source, and maintaining a 3-second delay operation to remind people near the ETC lane to avoid vehicles.
When the vehicle leaves the toll channel, the radar monitor does not detect a signal and will automatically turn off the point light source. The control power system is not working and will not cause interference to the work of toll collectors and vehicle traffic. At the same time, the system has four major system protection functions: "short circuit protection", "surge protection", "leakage protection", and "voltage stabilization control", ensuring the safe operation of the ETC lane point light source control system on the highway.
6. Door crane grab warning light system
In February 2022, the gantry crane grab warning system developed by the Equipment Technology Room Information Center of Shandong Rizhao Lanshan Company was officially unveiled, providing "escort" for ship loading and unloading operations and adding a beautiful scenery to the Rizhao Port area under the night. This system integrates visible light projection, laser, and light sensing functions, and is installed on the gantry crane's elephant nose bridge to project light columns towards the grab. At the same time, gyroscope stabilization technology is used to ensure its operation. The driver of the gantry crane can independently control the system in the driver's cab, and combine warning lights reasonably based on the lighting conditions and on-site working environment, to achieve the best system efficiency in different states. At night or when the line of sight is unclear, visible light projection follows the operation of the gantry crane grab, projecting a light column towards the grab, forming a light and dark alternating light column projection directly below. The green laser column constantly displays the overall movement trajectory of the gantry crane arm, warning the working machinery and personnel on the shore, deck, and cabin. The installation and use of the gantry crane grab warning system can help the gantry crane driver concentrate, prevent fatigue operation, and assist the driver in carrying out hopper operations, More stable and faster entry, exit, and unloading operations, improving safety production levels.
7. MMD Smart Road Lighting System
In December 2021, at the 5th "Maker Guangdong" competition, Professor Zhao Haitian's team from Shenzhen University won two awards from the maker group for their "MMD Smart Road Lighting System".
This system can transform its own form according to the different weather and road conditions faced by the driver, and change the lighting mode according to the situation, which is more in line with the driver's visual habits, meets the driving needs, provides intelligent and humanized services for the driver, and truly achieves the goal of humanistic return.
In addition, the system also pays attention to the survival needs of other organisms around the city, effectively reducing the interference of traditional lighting on other organisms at night by reducing the height of lighting fixtures, making a certain contribution to the ecological protection around street lights, in line with the current concept of biodiversity.
8. Dual carbon digital lighting energy management system
In August 2021, the Hangzhou Jinqu section of the dual carbon energy management expressway under Zhejiang Provincial Transportation Group completed the equipment IoT transformation, marking the official launch of the first dual carbon digital energy management expressway in China. It can obtain real-time data on tunnel lighting and achieve energy conservation and consumption reduction through precise management.
The management platform of this system monitors the energy consumption of the tunnel lighting system at each time period, and develops intelligent adjustment plans for lighting in different scenarios based on the situation where the daily energy consumption of tunnel lighting is much higher than at night. It distinguishes adjustment scenarios for sunny, rainy, and foggy days, tracks carbon emissions in real-time, and achieves carbon monitoring.
9. Intelligent energy-saving control system for canopy lights
In January 2021, the toll station under the jurisdiction of Zhejiang Zhoushan Management Center launched a self-developed intelligent energy-saving control system for canopy lights. The rain shed lights controlled by this system can achieve intelligent and precise switching. Based on the power saving of 1 kilowatt hour per light, it can save over 20000 kilowatt hours of electricity throughout the year.
With the help of the intelligent energy-saving control system for awning lights, members of the "Huiqiao Innovation Studio" at Zhoushan Management Center, based on the actual lighting needs of toll lanes, use time controllers, photosensitive controllers, and lane toll systems to achieve intelligent and precise control of awning lights for "one lane, one control", which compensates for the power waste caused by turning on all awning lights at the toll station with one switch. The system can also automatically adjust the number of canopy lights that need to be turned on based on the on-site lighting darkness and lane opening conditions. It can also turn on and off the power supply reasonably according to the predetermined switching time to avoid energy waste. When the lane is closed and the sky darkens, the system will automatically turn on one of the canopy lights in the lane to meet basic lighting requirements; When the lane is open and the sky darkens, the system automatically turns on all the canopy lights in the lane to ensure safe passage.
10. Intelligent photoconductive lighting system
In March 2018, Chongqing and its Optoelectronic Technology Co., Ltd. developed an intelligent photoconductive lighting system, bringing pure natural sunlight to residential, underground engineering, production workshops and other scenes.
The intelligent light guide lighting system adopts a mode of "optics+automatic control+intelligent light compensation", which can collect light sources 24/7 based on the sun's direction, and perform artificial intelligence LED light compensation when the light input is insufficient. From the structural details of the intelligent photoconductive lighting system, the newly developed optical path tube has a diameter of only 50 millimeters and a reflectivity of over 99%. Each refractive point only needs to install a small splitter, which can greatly reduce the loss of the light source. In addition, the system uses a small tube optical path, which is also easy to lay and saves installation costs.
Whether it's airports where planes frequently take off and land, roads where cars come and go, ports where ships run endlessly, or schools for education, the lights of the digital era are everywhere, fulfilling different universal values. Looking forward to the future, as the cross-border development trend of the lighting industry intensifies, more new intelligent lighting control systems will inevitably emerge, illuminating the overall direction of technological change.
