After the continuous development of the computer system in the 1950s and the full development of the Internet in the 1990s, these have affected the technological innovation of human development and have promoted the upgrading of major industrial chains. This has been accompanied by the Internet of Things and The arrival of the car networking era.
Car networking is simply to connect the car to the Internet, allowing car users to apply more experience while reporting the real-time operation information of all aspects of the car. The service center or other organization can provide more comprehensive customized services. .
What is ETC system
The ETC system is a new type of electronic automatic charging technology for roads, bridges and tunnels. It uses the dedicated short-range communication (DSRC) between the vehicle-mounted electronic tag and the microwave antenna to automatically complete the entire charging process without requiring the driver to stop and any other toll collectors to take any action.
Three characteristics: no parking, no people, no cash
What is the principle of the ETC system?
Intelligent Transportation and Vehicular Learning: About ETC Electronic Toll Collection System
ETC system uses vehicle automatic identification technology to complete wireless data communication between vehicles and toll stations, automatic vehicle identification and exchange of relevant toll data, and processing of toll data through the home computing network to realize full electronic toll collection system for automatic charging without stopping. . After the vehicle has mounted the vehicle-mounted device, when the vehicle is driven to the ETC lane, the detector mounted on the lane receives the signal transmitted from the vehicle-mounted device, and the railing is automatically lifted to allow the vehicle to pass.
What is the key technology of ETC system
The ETC lane is similar to the traditional MTC lane construction and mainly consists of an ETC antenna, a lane controller, a fee display, an automatic barrier, and a vehicle detector.
Key technologies
Automatic Vehicle Identification Technology (AVI)
Automatic Vehicle Classification Technology (AVC)
Short-range Communication Technology (DSRC)
Escape capture system technology (VES)
Infrared technology
How to develop the next step of ETC
Intelligent Transportation and Vehicular Learning: About ETC Electronic Toll Collection System
The rapid development of ETC technology, according to statistics, the total number of users as of May this year, the entire network of users exceeded 50 million, the main line ETC lane coverage of more than 98%.
So, in the early development of ETC, the next step is how to go?
1. In the aspect of ETC application expansion project, it is necessary to further improve the convenience of ETC installation and payment, and to emphasize the use of ETC in various types of operational vehicles such as road passenger vehicles and taxis.
2. To study and promote the standard van-type non-stop charging, increase the service level of customer service outlets and provincial network settlement centers, and establish an efficient settlement system.
3, improve the use of ETC
This year, the State Council released an indicator mentioned in the “Thirteenth Five-Year Plan†for comprehensive transport, and the utilization rate of ETC in 2020 should reach 50% or more, but now it is only 15%, and this usage rate has a decreasing trend. The frequency of using ETCs in the early stage is relatively high, and the lower the frequency of using the ETCs, the more an inevitable trend.
Now all provinces and cities have some promotions, such as the installation of electronic tags to sell discounts or free, freeway tolls to enjoy certain discounts. It is estimated that the number of users of ETC is now about 35% of the total number of vehicles, and it is expected to reach 50% utilization rate, which is equivalent to the number of automobiles from 95 to 100 million, and the number of vehicles is still growing rapidly, 100 million ETC. Users can barely achieve 50% of the indicators.
PVC Edge Banding For Cabinet
The main function of the edge banding is to seal the cross-section of the board, so as to avoid the damage of the board and the adverse factors (mainly moisture) in the process of use and prevent the formaldehyde inside the board from volatilizing, and at the same time achieve the effect of beautiful decoration.
The product has the following main features: smooth surface, no blistering, no ribbing, moderate gloss, smooth surface and back surface, uniform thickness, uniform width, reasonable hardness, high elasticity, good quality, strong wear resistance, trimmed and sealed The color of the side and the side is close to the surface color, not whitish, good gloss, and the overall color of the finished furniture is coordinated.
Judge good or bad
1. Look at the hue and surface roughness of the edge banding strip. The color of the surface of a good edge banding strip is also very important. Whether the color is close to the customized product and is gorgeous. If the surface is very rough and there are pull marks, the quality is definitely not much better. This is the surface quality of the edge banding strip. It has nothing to do with the quality of the inner material of the edge banding, mainly the production process of the edge banding factory and the production technical skills of the employees. A good edge banding strip is: the surface must be smooth, no blistering or seldom bubbling, no drawing or few drawing, moderate gloss, not too shiny or too matte (unless there are special requirements).
2. Check the flatness of the surface and bottom of the edge banding and whether the thickness is uniform, otherwise it will cause the joint between the edge band and the board, the glue line is too eye-catching or the gap between the board and the edge band is too large, which will affect the overall beauty. Details determine success or failure, and often a small detail problem may bring an embarrassing situation where the overall effect is not good.
3. Whether the edge trimming is whitish, whether the surface of the bent edge strip is severely whitish, and whether the ground color of the trimming strip is close to the surface color of the board in question. PVC Edge Banding strips are mainly made of PVC and Calcium Carbonate plus additives. If the calcium carbonate content is too high, whitening of the edge banding and bending will occur, which proves that the quality of such products is not good.
4. Whether the strength is okay and whether there is elasticity. High strength means good wear resistance, and the corresponding quality is better. Too high strength also means increased processing difficulty. Low elasticity means low wear resistance and low aging resistance. In addition, according to actual production needs, manual trimming is generally required, and soft spots can be made appropriately, and the automatic edge banding machine can make hard points appropriately.
5. Whether the adhesive is applied evenly and whether it is easy to fall off during use.
6. Smell whether the PVC edge banding strips taste or not. Products produced with good quality raw materials generally have a small taste. If the taste is too large, it means that the quality of the raw materials used in production is relatively poor.
