Nanshan community license plate recognition monitoring installation / preferred manufacturer of electronic induction parking system
Nanshan community license plate recognition monitoring installationLicense plate recognition is applied to electronic police No.1 monitoring system, such as red light driving monitoring system, overspeed monitoring system, retrograde monitoring system, traffic violation monitoring system, public traffic lane monitoring system, non motor vehicle lane traffic monitoring system, etc.Recognition principleStrong light shielding: on the basis of low illuminance color camera, the brightest part of the image is shielded by the function of software. In traffic monitoring, it can block the strong light of headlights and capture the license plate clearly. But the biggest disadvantage of this camera is that the software can´t distinguish clearly, the brightest part of the image can´t be clearly defined, which may block the license plate number, and can´t handle the capture of high-speed moving objects. At present, there are many domestic cameras in the strong light shielding, the effect is different.Adjustable electronic shutter: for the capture of high-speed moving objects (the speed on the highway is generally above 70km / h), clear capture can be achieved by reducing the electronic shutter speed, which is generally manually adjusted. But the biggest problem with this method is that the illuminance is different between day and night. Two shutter speeds must be set to accommodate day and night monitoring, respectively.Wide dynamic function: This is the best way to solve the influence of light on the capture effect. The big news was first put forward by Panasonic. When the background light is too bright, ordinary camera can not solve the problem of light and dark image display.At present, the car 1 board recognition system is a more advanced device for the current car parking lot. The board 1 identification system adopts full-automatic barrier, digital vehicle detector, multi line electronic display screen, light supplement equipment and vehicle monitoring camera, so that the owner can enter and leave the parking lot without stop and automatic transmission. A set of unloading device specially designed for automatic driving lock to prevent external force damage. In order to ensure light, stable and low input power, a set of balance mechanism and anti smash control system are adopted to ensure the safety of parking. The digital vehicle detector uses digital logic judgment to replace the traditional analog switch judgment, to ensure the accuracy of the judgment, to design the performance throughout the day, to eliminate the impact of external environment changes on the system, to quickly respond to the design, to adapt to the operation system of large vehicle flow; multi line electronic display screen, So car owners and parking lot managers can master the information of the remaining parking spaces in the parking lot for the first time, and when the vehicles enter and leave the parking lot, they can read the number of car 1 brands and display the payment amount and other information; they can use them in the light deficient environment. Choose stable operation, low heat output, low energy consumption, long service life make-up light is the first choice.
