Problems solved by technology

When the current license plate recognition device is used in cloudy and rainy weather, it is impossible to avoid contact between rainwater and the lens end of the license plate recognition camera, resulting in water droplets remaining on the lens end, which will cause recognition errors and reduce recognition accuracy. , it is impossible to accurately fill light on the license plate when the license plate recognition camera recognizes the license plate, which further reduces the recognition accuracy and is inconvenient to use

Embodiment 1

[0023] Example 1: Please refer to Figure 1-4 , a license plate recognition device for a parking lot, comprising a base 1, a universal pulley 2 is fixedly connected to the front, rear, left, and right under the base 1; a support mechanism 3 is fixedly connected to the upper middle of the base 1, and the support mechanism 3 is fixed There is a telescopic mechanism 4, the telescopic mechanism 4 is fixedly connected with a fixed mechanism 5, and the fixed mechanism 5 is fixedly connected with a driving mechanism 6, when the supplementary light does not illuminate the license plate of the vehicle, the driving motor 601 can be turned on, and the driving motor 601 The rotation of the output end drives the rotation of the motor shaft 602, which in turn causes the turntable 603 fixedly connected to it to rotate, and then makes the drive rod 604 fixedly connected to the turntable 603 to rotate around the motor shaft 602, and then drives the transmission member 605 to move, and then make...

Embodiment 2

[0034] Embodiment 2: This embodiment is a further improvement of the previous embodiment: the prime mover 1002 is a servo motor.

[0035] The connection between the U-shaped block 802 and the longitudinal bar 402 is welding.

[0036] The working principle of the present invention is: when the supplementary light does not shine on the license plate of the vehicle, the drive motor 601 can be turned on, and the output end of the drive motor 601 rotates to drive the rotation of the motor shaft 602, thereby causing the turntable 603 fixedly connected to it to rotate, and then The driving rod 604 fixedly connected with the turntable 603 rotates around the motor shaft 602, and then drives the transmission member 605 to move, and then the rack bar 606 moves, and then the L-shaped plate 701 is rotated, and then the L-shaped plate 701 is fixedly connected. The supplementary light 703 adjusts the angle so that it can shine on the license plate of the vehicle; when it is raining, the prim...

Abstract

The invention discloses a license plate recognition device for a parking lot, and relates to a recognition device, the license plate recognition device comprises a base, and universal pulleys are fixedly connected below the base in a front-back and left-right symmetrical manner; a supporting mechanism is fixedly connected to the middle of the upper portion of the base, the supporting mechanism is fixedly connected with a telescopic mechanism, the telescopic mechanism is fixedly connected with a fixing mechanism, the fixing mechanism is fixedly connected with a driving mechanism, the driving mechanism is matched with a light supplementing mechanism, and the telescopic mechanism is fixedly connected with an adjusting mechanism. The adjusting mechanism is rotationally connected with an auxiliary mechanism rotationally connected with the telescopic mechanism, the auxiliary mechanism is fixedly connected with a prime mover mechanism, and the prime mover mechanism is in threaded connection with a recognition mechanism. By arranging the prime mover mechanism, the recognition camera can be moved by a certain distance into the C-shaped frame, so that the problem that rainwater falls on a recognition lens of the recognition camera during raining, and consequently recognition cannot be carried out or recognition errors are caused is solved.

Description

technical field [0001] The invention relates to a recognition device, in particular to a license plate recognition device for a parking lot. Background technique [0002] With the popularization of civilian cars, most parking lots use license plate recognition systems to effectively and standardize the management of vehicles entering and leaving the parking lot. The license plate recognition system refers to the technology that can detect vehicles on the monitored road and automatically extract vehicle license plate information for processing , especially when used in outdoor parking lots, it is easily affected by environmental factors. When the current license plate recognition device is used in cloudy and rainy weather, it is impossible to avoid the contact between rainwater and the lens end of the license plate recognition camera, resulting in water droplets remaining on the lens end, which will cause recognition errors and reduce the recognition accuracy. , It is imposs...
