Every morning, we are able to see sprinklers, sweepers and other large sanitation vehicles drove slowly forward on the road to bring clean and order to our city. But what we do not know is that large vehicles like this want to reverse or turn, but it is a hassle - because the body is too large, the rear of the vehicle and the side is easy to form a blind perspective, a little inattentive, there will be danger. In August 2011, the reporter learned that in recent days, Wenxin, Hangzhou's Xihu District, has had three large-scale sanitation vehicles with “eyes†behind it. "The appearance of the vehicle has not changed at all, but we have installed a real-time dynamic observation system for our own research and development vehicle to solve the problem of blind spots in the view of driving." Tang Yongzhan, director of the Hangzhou Wenxin Environmental Sanitation Institute, told the reporter: "Every car costs only 2,000 yuan. Yuan Qian, who installed three cameras on the rear and two sides of the vehicle, solved the problem that caused the sanitation vehicle driver to suffer headaches." Originally, these three vehicles were sprinkler, machine sweeper and cleaner, sprinkler and automatic sweeper, all of which were "big guys" over 7 meters in length and more than 2 meters in width. According to the Director of the Tang Dynasty, the “vehicle real-time dynamic observation system†was installed on the vehicles of this sanitation vehicle. Three color cameras were installed on the left, right, and rear sides of the vehicle body. The cameras and high-brightness color Connected to the display screen, real-time display of the road conditions on the rear and both sides of the vehicle. Drivers do not need to pay close attention to the rearview mirror when they are driving, so they can observe the real-time dynamic status of the work surface. Sitting in the high cab, reporters who used to drive cars often found the difference between this large-scale sanitation vehicle and the ordinary vehicle. Because the body of a large sanitation car is very wide. For example, this reporter has entered the three-in-one vehicle. The width of the car body has reached 2.5 meters. The driver holding the steering wheel wants to see the situation on the right side of the vehicle and must turn his head to the right. On the side, even if this is the case, the bottom of the vehicle is still a blind zone of view, and it is easy to distract from the front of the vehicle. At the same time, because the rear of the vehicle carries water storage tanks or bins, the driver does not see the road conditions at the rear. "It's okay, we have this." Then, the driver of the sanitation vehicle Xiao Zheng opened the switch of the color display, and the high-definition picture immediately jumped into the eye - directly in front of the steering wheel, it was the road condition at the rear of the vehicle, right front On the display, the situation on the right side of the vehicle is also clear. "Before we had to reverse, we must have someone in the rear. Although it was slow, it was also awkward when turning. Now the vehicle can be seen both before and after, and the car is even better." "If you say such a big sprinkler is slow, but it will always be on the road every day, safety must be put first!" Understand the working principle of this system, and the pedestrians gathered from hearing the news Appreciating the nod, and the uncle's uncle's words are even more inspiring. "Now that there are so many large-scale construction vehicles in trouble, it is estimated that there is also a relationship with the blind spot. It is better to let the engineering vehicles entering the city also have this system installed. Gives us all more security guarantees." The reporter said: Traffic accidents caused by large-scale engineering vehicles are frequently reported to the newspapers. In July 2011, only five engineering vehicle accidents occurred in Hangzhou. Although there are many reasons for anecdotal accidents, many old drivers believe that due to their large size, construction vehicles are prone to blind spots of view, posing a very big threat to traffic safety. The new real-time dynamic observation system of the Wenxin Sanitation Institute will eliminate blind spots for large-scale engineering vehicles and improve the driving safety factor. I believe it will also help. Ms Ploymer,Silylated Polyurethane,Ms Polymers,Silane-Modified Polymers Nanjing Manta New Material Co., Ltd. , https://www.mantasil.com
