An intelligent parking lot based on a shunt drive type self-control power supply circuit

Abstract

The invention provides an intelligent parking lot based on a shunt drive type self-control power supply circuit. The intelligent parking lot comprises a parking lot body with a plurality of parking spaces, an entrance barrier gate arranged at an entrance of the parking lot body, an exit barrier gate arranged at an exit of the parking lot body, a control room adjacent to the exit barrier gate, a controller arranged in the control room and connected with the entrance barrier gate and the exit barrier gate, a multifunctional display screen connected with the controller, and a license plate camera connected with the controller and used for taking pictures of license plates. A power supply input end of the controller is provided with a self-control power supply circuit which is provided with a shunt drive circuit used for driving the license plate camera. The intelligent parking lot based on a shunt drive type self-control power supply circuit has the advantages that equipment operation is better protected, the service life of equipment is prolonged, the using effect of the equipment is improved, and the using cost is reduced.

Description

technical field [0001] The invention belongs to the field of intelligent parking lots, and specifically refers to an intelligent parking lot based on a shunt-driven self-control power supply circuit. Background technique [0002] In today's society, cars are already an irreplaceable means of transportation. With the popularity of cars, people's lives are becoming more and more convenient. Nowadays, underground parking lots are built in residential areas, office buildings, shopping malls and other buildings for parking vehicles. In order to increase the use effect, many parking lots connect multi-function display screens to controllers, while existing controllers are connected to display screens. The effect is not good, and the transmission effect of the information transmitter on the controller is poor, and it is difficult to achieve the effect of connecting through a physical line. At the same time, the controller is greatly affected by the power supply, and is often damag...

AI Technical Summary

Problems solved by technology

Nowadays, underground parking lots are built in residential areas, office buildings, shopping malls and other buildings for parking vehicles. In order to increase the use effect, many parking lots connect multi-function display screens to controllers, while existing controllers are connected to display screens. The effect is not good, and the transmission effect of the information transmitter on the controller is poor, and it is difficult to achieve the effect of connecting through a physical line

At the same time, the controller is also greatly affected by the power supply, and is often damaged due to fluctuations in the power supply, which increases the cost of the product.

[0003] Due to the different driving skills of the drivers, it is often difficult for drivers to get the card due to inappropriate parking positions, and some drivers even need to get off the car to get the card to enter the gate, which greatly reduces the efficiency of vehicle admission

Therefore, many parking lots use cameras to record the number plates, which eliminates the need for the driver to take the card to enter the gate, and improves the speed of entry. However, the power supply of the existing cameras is directly connected to the power supply, which is subject to The power supply interference is relatively large, so that the camera is easily damaged under the power shock
