Example Embodiment

[0018] Example 1

[0019] See Figure 1-3 This embodiment provides a method and device for recognizing a license plate, including a main body 1, a processor 7 and an access control rotating motor 2 are provided on the main body 1, and an access control connecting block 3 is fixed on one side of the access control rotating motor 2. 3 There are several, and the left and right sides are respectively provided with a card block 31 and a card slot 32. The access control connection block 3 is clamped to each other through the card block 31 and the card slot 32, and the card block 31 and the card slot 32 are fixedly connected with a conductive connection. In block 8, a stop 33 is installed at the junction of adjacent access control connecting blocks 3 through spring rotation, and the rear end of the last access control connecting block 3 is clamped with the outer end block 4 through the clamping block 31 and the card slot 32, and the outer end block 4 is inside Set the alarm 5.

[0020] In this embodiment, when the access control connecting block 3 is used, the adjacent card blocks 31 and the card slot 32 are spliced together, so that the multiple access control connecting blocks 3 are spliced into a long-bar access control, and a stop 33 is provided to restrict the card block 31 and the card slot. The offset of the slot 32 ensures stable splicing between the access control connecting blocks 3;

[0021] When the access control connecting block 3 is hit by a vehicle, the connection between the locking block 31 and the slot 32 between the adjacent access control connecting blocks 3 changes. Because the stop 33 is installed on the access control connecting block 3 by a spring rotation, the stop 33 is biased. The restriction on the offset of the card block 31 and the card slot 32 is lifted, and the splicing between the access control connection blocks 3 is interrupted, resulting in the access control connection block 3 being scattered on the ground. Compared with the existing access control, the vehicle , Driver and pedestrian injury;

[0022] An alarm 5 is set, and wires and conductive connection blocks 8 are arranged inside and on both sides of the access control connection block 3. When the access control connection block 3 is separated by a vehicle impact, the connection between the alarm 5 and the processor 7 is interrupted, and the alarm The device 5 sends out an alarm to remind others to reduce the injuries suffered by others, and a conductive connection block 8 is provided to facilitate the connection of the wires in the structure when the access control connection block 3 is connected.

Example Embodiment

[0023] Example 2

[0024] See Figure 1-4 , A further improvement is made on the basis of embodiment 1: a sensor 6 is provided on the main body 1, and the sensor 6 is connected to the processor 7 through a wire. The left and right sides of the access control connection block 3 are fixed with reflective paper 34 and a stop 33 It is arranged on both sides of the card block 31 and the card slot 32. The front end of the card block 31 and the inside of the card slot 32 are both set in a matching trapezoid shape. The alarm 5 is connected to the processor 7 through a conductive connection block 8 and a wire. It is connected to the access control rotation motor 2 through a wire, a control button 9 is provided outside the main body 1, and the control button 9 is connected to the access control rotation motor 2 through a wire.

[0025] In this embodiment, when the access control needs to be opened, a remote control that matches it is set outside the sensor 6, and a signal is sent through the remote control. The sensor 6 receives the information, transmits it to the processor 7, and then transmits it to the access control rotating motor On 2, drive the access control connection block 3 to rotate, so that the access control opens; in addition, you can directly transmit the signal to the access control rotation motor 2 by operating the control button 9, and drive the access control connection block 3 to rotate, so that the access control opens;

[0026] Set up the reflective paper 34, when the car lights shine on the access control connection block 3 at night, the reflective paper 34 emits a warning light to remind the driver;

[0027] The front end of the locking block 31 and the inner side of the locking slot 32 are both arranged in a matching trapezoid shape, and the trapezoidal structure maintains the stability of the locking.

[0028] Among them, the specific model of the processor 7 is S7-200, the processor 7 is connected to the community system through a wire, the alarm 5 is a power failure alarm, and its specific model is DD-MZT, and the sensor 6 is an infrared sensor, and its specific model It is ZP-5H.
