Vehicle license plate recognition (VLPR) is an application of computer video image recognition technology in vehicle license plate recognition.
The license plate recognition technology can extract and identify the license plates in motion from complex backgrounds, and identify vehicle license plate numbers through techniques such as license plate extraction, image preprocessing, feature extraction, and license plate character recognition. The current technology level is alphabetical and numerical. The recognition rate can reach 96%, and the recognition rate of Chinese characters can reach 95%.
License plate recognition is widely used in the management of highway vehicles. In the Electronic Toll Collection (ETC) system, it is also the main means to identify vehicle identities in conjunction with DSRC technology.
In the management of parking lots, license plate recognition technology is also the main means of identifying vehicle identities. In the Technical Requirements for the Collection and Transmission System of Vehicle Image and Number Plates in Parking Garage (Field), which is built by the Shenzhen Municipal Bureau, the license plate recognition technology has become the main means of vehicle identification.
The license plate recognition technology combines with the electronic toll collection system (ETC) to identify vehicles. When passing vehicles pass through a crossing, there is no need to stop, that is, automatic identification of vehicles and automatic charging can be realized. In the yard management, in order to improve the efficiency of the entrance and exit vehicles, the license plate recognition is aimed at vehicles that do not need to collect parking fees (such as monthly trucks, free-of-charge internal vehicles), and build unattended expressways, exempting card access and non-stop access experience. Change the management mode of access to the parking lot.

Gear Pumps are capable of moving small suspended solids but due to the meshing of gears they can be damaged by pumping large solids. When solids are present in the fluid they may act as abrasives, causing damage to the gears and increasing downtime. In terms of construction materials, gear pumps can be made from a wide variety of materials, ranging from alluminum, iron and stainless steel to cast iron, depending on the application and fluid properties (abrasive, corrosive etc.)
