With the development of society, technological progress, and the vigorous development of Internet technology, more and more parking lots now use smart devices to improve management efficiency by accessing the Internet. Traditional parking systems are no longer available due to personnel costs and management efficiency. To meet people's needs, parking lot managers have retrofitted and upgraded traditional parking lot systems.
At present, the traditional parking lot management system is prone to congestion at the entrance and exit of the parking lot during the rush hour. The traffic efficiency is extremely low, followed by the simple function of the system, which only plays a role of one car and one stop in the parking lot, and does not have the functions of helping the owner to find a parking space, find a car, and quickly pay a fee. The manual charging adopted also faces problems such as funding loopholes, change receipts, etc. Through LAN communication, an independent database and front-end display must be installed in the parking lot during installation. Client software is installed and run on the front-end display. This not only has a large amount of engineering, It takes a long time, and the system has poor scalability and maintainability. On the other hand, the intelligent parking lot management system uses a fully automatic computer management mode. From the exit of the parking lot to the gates to the management center, all of them are automatically controlled by computers. It is very convenient to manage and the vehicles enter and exit the parking lot. And it can easily realize unmanned operation at the entrance and exit, and automatically charge, which can greatly save costs. Therefore, the intelligent parking lot system that can meet the needs of managers and car owners has a very high potential, and the future development prospects are very broad.
The transformation of the traditional parking lot system can use advanced license plate recognition technology to clearly capture vehicle information and character images, allowing car owners to enter and exit the parking lot without parking. It can also monitor the operating status of all online equipment, realize equipment failure pre-discovery, self-repair, and query various reporting functions in real time, and provide customers with inquiries on-site conditions in the form of multiple pictures. Sexual restrictions have been achieved remote management nationwide. The parking lot charging system adopts automatic charging, which supports the current popular mobile payment (Alipay, Weixin). Owners can pay for scanning by app or log in to a special parking app to pay. The whole process is fast and convenient.
Magnetic Pump
Centrifugal pumps are used to transport fluids by the conversion of rotational kinetic energy to the hydrodynamic energy of the fluid flow. The rotational energy typically comes from an engine or electric motor. They are a sub-class of dynamic axisymmetric work-absorbing turbomachinery. The fluid enters the pump impeller along or near to the rotating axis and is accelerated by the impeller, flowing radially outward into a diffuser or volute chamber (casing), from which it exits.
Common uses include water, sewage, agriculture, petroleum, and petrochemical pumping. Centrifugal pumps are often chosen for their high flow rate capabilities, abrasive solution compatibility, mixing potential, as well as their relatively simple engineering.A centrifugal fan is commonly used to implement an air handling unit or vacuum cleaner. The reverse function of the Centrifugal Pump is a water turbine converting potential energy of water pressure into mechanical rotational energy.
