"Old urchin" invented traffic lights color blindness can also understand

"The red light stops, the green light goes, and the traffic rules must be observed." This well-known traffic rule appeared in front of color blindness: they could not distinguish the traffic lights because they could not distinguish between red and green colors. Lu Gang, a retired teacher of Nanjing No. 6 Middle School, used the principle of “horselights” to design a new type of monochrome traffic light, which made the red and green blinds visible and easy to understand. Currently, this invention patent is pending.

Obsessed with inventions, dubbed "old urchins"

When he mentioned Lu Gang, there is no one in Nanjing science and technology invention industry. He has been a science and technology tutor for more than 20 years in Nanjing Sixth Middle School. In the annual youth science and technology innovation contest, his students can always win the "new gadgets" award. "You look for Lu Gang, he has a lot of stories about 'old urchins'. 1 Yesterday morning, the reporter went to Nanjing Sixth Middle School for an interview. People familiar with Lu Gang said that he is an "old urchin". He is 62 years old and laughs all day. Hehe is mixed with a group of children.

In the library of Nanjing No. 6 Middle School, the reporter saw Lu Gang. He is dressed casually, with long hair fluttering, very avant-garde, and looks like he is in his forties. "40 years old? Haha, I am so young, but I am a little cheerful." Lu Gang told reporters that he is optimistic and curious. He has always liked to invent and create things when he was young. Later, he served as the school's science and technology tutor, led a group of children to study the invention, not only did not bother him, but also made his mind a lot younger.

"New Marquee" principle design new type of traffic light

"Because of my curiosity, I saw a bunch of people on the street. I also like to squeeze in and watch the fun." Lu Gang told reporters that he was not the same as ordinary people. When he saw someone quarreling, he turned around and left. But if you meet those who crashed, you have to go see it. When the car accident was much more, he wondered if a technology could be used to reduce the occurrence of a car accident. After research, Lu Gang found that about 75% of human color blindness is red-green blind, and the traffic lights that command road traffic in big cities are just traffic lights, which increases the probability of accidents invisibly.

Is there any way to improve the red-green color of traffic lights? In a friend chat, Lu Gang was inspired: If a monochrome traffic signal is designed with the folk "horse" principle, the dynamic change of monochromatic light is used to direct pedestrians, so that red and green blindness can also be identified. After N revisions of the design, not long ago, Lu Gang took out the design model of this new monochrome traffic light.

Optical dynamic indicator color blindness can also be seen

"Monochrome traffic lights, the overall color is striking orange, the illuminant still uses LEDs." Lu Gang pointed to his design to introduce to reporters, from the vertical, this kind of signal light is nothing special, still marked with arrows "Left, middle and right" three modes of travel. However, from the horizontal perspective, the famous hall is big. The bottom line is to display the three directions of “left, center and right” with orange-red LED lights, which are long-term bright, and the middle row is three boxes filled with LED lights. Just above the direction sign, if the light is on, it will block the direction mark below, indicating that this direction cannot pass. At the top is the dynamic indicator light, which is the key part of the signal light. It is illuminated by the LED interval, like a “horselight”, which is very intuitive to indicate that it can pass in one direction.

"The biggest advantage of it is to change the color indication to optical dynamic indication, which can be distinguished by anyone with color blindness. In addition, the production cost is low, only one 'four-sided lamp' is needed at a junction." Lu Gang said that the only regret is The current international traffic signals are all traffic lights. It is not easy to change this habit. It can only pin your hopes in the future.



Parking door anti-collision device to avoid small touch

Lao Lu told reporters that there are still many small inventions that he personally operates or instructs students to design. Among them, a device that has recently been invented to open the door and prevent collision is cheap and practical, and has just been in the Baixia District Youth Science and Technology Innovation Competition. In the award, he won the municipal competition qualification.

According to Lu Gang, his inspiration for inventing the "parking door collision avoidance device" is also from a car accident. One of his acquaintances accidentally was hit by a cyclist when the car was opened. The door was damaged and the bicycle was broken. The person fell. "If you design a sound and light reminder similar to reversing, this problem can not be solved." Lu Gang said that he did it, he bought a language chip and LED lights, and also made a car model by himself. Soon after, An anti-collision parking door alarm device was introduced.

Yesterday, the reporter saw this new invention in Nanjing Sixth. "Please pay attention to opening the door, please pay attention to open the door..." Turn on the power, open any door, please pay attention to the safety voice prompts, and at the same time, install the LED in the corner of the rear window of the car. .

“After people see the light of 'Attention to open the door', the speed will slow down and there will be voice prompts nearby, which can avoid many similar bumps and rubs.” Lu Gang said that this new type of defense The impact device is only a hundred dollars in production cost, and it is not complicated to install. It is a practical invention.

Remind you of the voice security door with the key

I forgot to bring the keys when I went out. It is estimated that many people have encountered such embarrassment. In order to prevent people from losing keys, Lu Gang used a language chip to add a voice reminder to the security door. This new type of voice security door not only reminds people to bring keys, but also tells people to turn off water and electricity before going out.

"Do you have the key? Doors and windows, water and electricity, but also the boiling water on the stove should also pay attention to off. 1 reporter saw this kind of voice security door in Lu Gang's office yesterday. The playful voice prompt makes people feel very interesting. "As long as When the hand touches the door handle and the power is turned on, the voice prompt will sound, reminding you to check the key and water and electricity to avoid accidents. "Lu Gang side presentation to the reporter: the installed security door, you can also add such a new voice prompt device later, the cost is probably within 100 yuan.
