The cold working methods of steel pipes mainly include cold drawing and cold rolling. The raw materials of cold-rolled steel pipes can be hot-rolled seamless steel pipes or welded pipes. The common characteristics of the cold working method of steel pipes are high dimensional accuracy and good surface roughness. It can produce very thin (up to 0.05~0.01mm) thin-walled tubes and very thin (up to 0.3~0.1 mm in diameter) capillaries.
Seamless Steel Pipe is a kind of pipe with hollow section, which is widely used to transport fluids, such as oil, natural gas, gas, water and some solid materials. Compared with solid steel such as round steel, steel pipe is light in weight when its bending and torsional strength is the same. It is a kind of economic section steel, which is widely used in pipeline engineering.

China's parking lot system is relatively late to start compared to foreign countries. However, after continuous efforts of industry professionals, the parking lot system in our country has continuously improved from the process of “taking a reading card, combining card and ticket, and license plate recognitionâ€. Now many products have Catch up to even exceed the level of international technology.
The earliest method of accessing the card by the parking lot system is to enter the parking lot through the issuance of a card by the staff. Upon exit, the management personnel collect the corresponding parking fee through the card information, and the vehicle can be played. However, such card management work is prone to the phenomenon of lost-cards. At the same time, the cost of card management is high, and the number of cards that can be accommodated in each ticket box is small, which is not suitable for the use of large-scale parking lots. In recent years, with the maturity of license plate recognition technology, the application of license plate recognition and card parking system in the market has been recognized by people. The license plate recognition parking system is a set of currently more advanced and popular equipment. It integrates cameras, flashlights, and control machines into one body. It is convenient for installation and debugging. When the vehicle enters or exits the parking lot, it triggers a sense of place and transmits the sense signal. The camera captures the license plate number of the vehicles entering and leaving the parking lot. Through the processing of the management center data, the lift bar lifts the vehicle to allow the vehicle owner to access the parking lot without taking a card.
With the improvement of people’s living standards, the number of motor vehicles in China continues to increase. In order to meet people’s parking needs, the parking management system must be developed in the direction of intelligent and unmanned management, making full use of license plate recognition, parking guidance, and countermeasures. To find vehicles, self-service payment and other functions to speed up the development of the industry.
For more information on the functions of the parking management system, parking lot collection system, parking lot barrier, access gate system, cloud parking lot, etc., please contact Shenzhen Daoer Intelligent Control Technology Co., Ltd., China Smart Parking Cloud Platform No. 1 Stocks, parking lot operators preferred partners.
Technical Development Course and Future Trend of China's Parking Management System
After more than 20 years of development, the parking management system has adopted the advanced parking technology and ideas from abroad. The parking management system in China has matured in the market. Although there are some deficiencies, it has been able to meet the current parking needs of people. Demand, from the ticketing to the current license plate recognition step by step toward the direction of intelligence.
