Description

Technical Field

[0001] This invention belongs to the field of barrier gate technology, specifically relating to an intelligent barrier gate, and also to an application method of the intelligent barrier gate. Background Technology

[0002] A barrier gate, also known as a vehicle barrier, is a specialized access control device used in roads, residential areas, parking lots, and other similar locations to manage vehicle access. It is widely used in these settings to manage vehicle entry and exit. Electric barrier gates can be raised and lowered independently via wireless remote control, or they can be automatically managed through a parking management system (i.e., an IC card management system): vehicles enter by taking a card and exit automatically after paying parking fees. A straight-arm barrier gate has a straight arm that remains straight in both horizontal and vertical positions. Driven by the gate's drive mechanism, it can be raised and lowered. In existing barrier gates, the arm is usually fixedly connected to the output end of the drive mechanism, allowing only vertical rotation for raising or lowering. When a driver is careless, the vehicle may collide with the arm. Since the arm and drive mechanism are fixedly connected, a collision can damage the vehicle or the barrier gate. Existing barrier gates do not take into account the protective design when the barrier arm is hit, or the secondary damage caused by the lateral swing of the barrier arm after the hit.

[0003] The anti-collision structure of the barrier gate arm with application number 201710886441.X, although it can protect the barrier gate arm and reduce secondary damage when it is impacted, has limited ability to reduce secondary damage through the gate arm fixing seat and blocking parts, and cannot actively reduce the speed according to the swing speed of the barrier gate arm after the impact. Summary of the Invention

[0004] The purpose of this invention is to provide an intelligent barrier gate and its application method to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, the present invention provides the following technical solution: an intelligent barrier gate, comprising a barrier gate control box, wherein the barrier gate control box drives a connecting rod, the outer end of the connecting rod has a connecting groove, the connecting groove is rotatably connected to a rotating pull rod at one end of the barrier gate arm via a rotating shaft, one end of the rotating pull rod is connected to a deceleration and stop mechanism via a steel wire rope, a drop-off radar is installed on the lower end face of the barrier gate arm, impact detection radars are provided on the front and rear sides of the barrier gate arm, a telescopic cylinder is provided on the side of the connecting rod, the locking tongue of the output end of the telescopic cylinder is inserted into the rotating pull rod, and the impact detection radar is electrically connected to the controller of the telescopic cylinder, the controller being used to control the extension and retraction of the telescopic cylinder;

[0006] The deceleration and stopping mechanism includes a rotating wheel, a coil frame, and a coil. The rotating wheel is rotatably mounted inside the barrier gate control box. The steel wire rope is wound around the rotating wheel, and a magnet is also mounted on the rotating wheel. The coil is wound around the coil frame. When the coil is energized, it generates a magnetic force in the opposite direction to the magnet. A speed sensor is also mounted on the rotating wheel. The speed sensor is electrically connected to the current controller of the coil. The current controller is used to control the current input of the coil. After the rotating wheel rotates as detected by the speed sensor, the current controller outputs current, causing the coil to generate a magnetic force.

[0007] Preferably, a brake disc is also connected to one side of the rotating wheel. An adjustable switch touch block is provided on the edge of the brake disc. A start switch and brake pads are provided on one side of the brake disc. The start switch is connected to a brake controller that controls the brake pads. When the switch touch block touches the start switch, the brake controller controls the brake pads to clamp the brake disc.

[0008] Preferably, a pitch motor is provided on one side of the connecting rod and inside the gate control box, and the pitch motor drives the connecting rod to pitch and rotate.

[0009] Preferably, the drop-off radar is electrically connected to the pitch motor.

[0010] Preferably, a guide wheel is installed inside the gate control box and on the right side of the turntable.

[0011] Preferably, the rotating wheel is also connected to a spiral spring, which is located on one side of the rotating wheel, and the center end of the spiral spring is connected to the central shaft of the rotating wheel.

[0012] A preferred method for applying an intelligent barrier gate includes the following steps:

[0013] 1) Impact detection radar detects vehicles approaching the barrier gate at a distance of 5-15cm;

[0014] 2) The impact detection radar sends a signal to the controller, causing the controller to control the retraction of the telescopic cylinder;

[0015] 3) When a car hits the barrier gate, the barrier gate swings, pulling the wheel to rotate via a steel cable;

[0016] 4) The speed sensor detects the rotation speed of the wheel, sets three speed thresholds, and controls the current controller of the coil current to output three different currents. The current increases in magnitude, and the magnetic force of the coil interacts with the magnet on the wheel to decelerate the wheel.

[0017] 5) As the wheel continues to rotate, the switch touch block touches the start switch, which activates the brake controller, controls the brake pads to clamp the brake disc, and stops the wheel from rotating.

[0018] The technical effects and advantages of this invention are as follows: This intelligent barrier gate and its application method allow the barrier gate arm to rotate upon impact, preventing breakage. Furthermore, a deceleration and stopping mechanism is incorporated, which uses a coil to generate magnetic force for active deceleration during rotation and brakes via brake pads. This prevents secondary damage caused by excessive swing speed due to excessive impact force. Attached Figure Description

Detailed Implementation

[0022] The specific embodiments of the present invention will be further described below with reference to the accompanying drawings. It should be noted that these descriptions are for the purpose of aiding understanding the present invention, but do not constitute a limitation thereof. Furthermore, the technical features involved in the various embodiments of the present invention described below can be combined with each other as long as they do not conflict with each other.

[0023] This invention provides, for example Figure 1-2 The intelligent barrier gate shown includes a barrier gate control box 1, a drive connecting rod 5 driven by the barrier gate control box 1, a connecting groove opened at the outer end of the connecting rod 5, the connecting groove being rotatably connected to a rotating pull rod 6 at one end of the barrier gate arm 2 via a rotating shaft 7, one end of the rotating pull rod 6 being connected to a deceleration and stop mechanism 9 via a steel wire rope 10, a guide wheel being provided inside the barrier gate control box 1 and located to the right of the rotating wheel 91 of the deceleration and stop mechanism 9, so that the steel wire rope 10 entering the rotating wheel 91 remains horizontal after passing through the rotating wheel 91. A drop-off radar 3 is installed on the lower end face of the barrier arm 2. A pitch motor is installed on one side of the connecting rod 5 and inside the barrier gate control box 1. The pitch motor drives the connecting rod 5 to pitch and rotate. The drop-off radar 3 is electrically connected to the pitch motor. When the drop-off radar 3 detects an impact, an impact detection radar 4 is installed on the front and rear sides of the barrier arm 2. A telescopic cylinder 8 is installed on the side of the connecting rod 5. The locking tongue of the output end of the telescopic cylinder 8 is inserted into the rotating pull rod 6. The impact detection radar 4 is electrically connected to the controller of the telescopic cylinder 8. The controller is used to control the extension and retraction of the telescopic cylinder 8.

[0024] The deceleration and stopping mechanism 9 includes a rotating wheel 91, a coil frame 93, and a coil 94. The rotating wheel 91 is rotatably mounted inside the barrier gate control box 1. A steel wire rope 10 is wound around the rotating wheel 91, and a magnet is also mounted on the rotating wheel 91. The coil 94 is wound around the coil frame 93. When the coil is energized, it generates a magnetic force opposite to that of the magnet. A speed sensor is also mounted on the rotating wheel 91, and the speed sensor is electrically connected to a current controller for the coil 94. The current controller controls the current input to the coil 94. When the speed sensor detects that the rotating wheel 91 is rotating, the current controller outputs current, causing the coil 94 to generate a magnetic force that repels the magnet and prevents the rotating wheel 91 from rotating. When the barrier gate arm 2 is subjected to a severe impact, the barrier gate arm... When the 2-beat speed is very fast, braking is achieved through the brake disc 92 of the hydraulic system. The deceleration and stop mechanism 9 also includes the brake disc 92. The brake disc 92 is also connected to one side of the rotating wheel 91. An adjustable switch touch block 95 is set on the edge of the brake disc 92. A start switch 96 and brake pads 97 are set on one side of the brake disc 92. The opening and closing of the brake pads 97 is controlled by the hydraulic system. The hydraulic system of the brake is quite common and will not be described in detail here. The start switch 96 is connected to the brake controller that controls the brake pads 97. When the switch touch block 95 touches the start switch 96, the brake controller controls the hydraulic system to brake. The brake pads 97 clamp the brake disc 92 under the action of hydraulic pressure, thereby braking.

[0025] The swivel wheel 91 is also connected to a spiral spring. The spiral spring is located on one side of the swivel wheel 91, and the center end of the spiral spring is connected to the central shaft of the swivel wheel 91. When the swivel wheel 91 rotates, it causes the spiral spring to coil and store energy. When the spiral spring releases the stored energy, it can drive the swivel wheel 91 to rotate in the opposite direction, so that the wound wire rope 10 is released.

[0026] This invention also provides a method for applying an intelligent barrier gate, comprising the following steps:

[0027] 1) The impact detection radar 4 detects vehicles approaching the barrier gate 2 at a distance of 5-15cm;

[0028] 2) The impact detection radar 4 sends a signal to the controller, causing the controller to control the retraction of the telescopic cylinder 8;

[0029] 3) When the car hits the barrier gate 2, the barrier gate 2 swings and pulls the rotating wheel 91 to rotate via the steel wire rope 10;

[0030] 4) The speed sensor detects the speed of the rotating wheel 91, sets three speed thresholds, and controls the current controller of the coil 94 to output three different currents. The current increases in magnitude, that is, the current controller outputs a larger current corresponding to the higher speed threshold. The magnetic force of the coil 94 interacts with the magnet on the rotating wheel 91 to decelerate the rotating wheel 91.

[0031] 5) As the wheel 91 continues to rotate, the switch touch block 95 touches the start switch 96, which activates the brake controller and controls the brake pads 97 to clamp the brake disc 92, causing the wheel 91 to stop rotating.

[0032] Although embodiments of the present invention have been shown and described above, it is understood that the above embodiments are exemplary and should not be construed as limiting the present invention. Those skilled in the art can make changes, modifications, substitutions and variations to the above embodiments within the scope of the present invention.
