Description

Technical Field

[0001] The present invention relates to the technical field of barrier gate control, and in particular to a barrier gate control opening method based on the Internet of Things. Background Art

[0002] Barriers, also known as vehicle barriers, are access management devices specifically used to restrict the movement of motor vehicles on roads. They are now widely used in highway toll stations and parking lot systems to manage vehicle access and to manage vehicle entry and exit. With the continuous development of the automobile industry and the increasing number of cars, the demand for barriers is also increasing, and higher requirements are placed on the performance of barriers.

[0003] Current barrier gate control generally only has one way of license plate verification, and is unable to verify the authorization time. Without authorization time verification, not only will parking resources be difficult to allocate reasonably, but also safety cannot be guaranteed, which may lead to chaos. At the same time, the mechanical components in the barrier gate equipment, such as gate rods and motors, are prone to wear, aging, failure and other problems during long-term and frequent use. If they are not discovered in time, it will affect the normal operation of the barrier gate. Therefore, this application provides a barrier gate control opening method based on the Internet of Things to meet the needs. Summary of the invention

[0004] The technical problem to be solved by the present invention is to provide a barrier gate control opening method based on the Internet of Things to solve the existing problems of being unable to verify the authorization time and being unable to promptly discover damage to barrier gate components.

[0005] In order to solve the above technical problems, the present invention provides the following technical solutions:

[0006] A gate control opening method based on the Internet of Things comprises the following steps:

[0007] S1, the vehicle arrives at the detection point;

[0008] S2, authenticate the vehicle;

[0009] S3, verification through the gate opening;

[0010] S4, monitors the gate status and provides feedback.

[0011] In a possible implementation, the identity verification in S2 includes license plate verification and authorization time verification.

[0012] In one possible implementation, the license plate verification includes local verification and remote verification. The main verification is that the camera automatically captures the license plate image when the vehicle arrives at the detection point, and then extracts the license plate number through the built-in image recognition algorithm and compares it with the locally pre-stored authorized license plate number list. If the match is successful, the gate control device is ready to perform the opening operation. The remote verification is after the vehicle arrives at the detection point, the communication module uploads the vehicle arrival information to the cloud platform, and the cloud platform sends the license plate information to the background permission management system for verification. The background system queries the corresponding authorization record in the database. If the vehicle has the right to pass, the cloud platform sends an opening instruction to the gate control device.

[0013] In a possible implementation, the authorization time verification is performed using the following algorithm:

[0014] Assume that the authorized time period of the vehicle is [t start ,t end ](For example, t start Indicates the start time, the format is such as 8:00,t end Indicates the end time, the format is 18:00), the current time is t current , convert the time into minutes (assuming that the total number of minutes in a day is 1440 minutes, and 0:00 in the morning is the starting point of 0 minutes) and compare. If t start ≤t current ≤t end , then the current time is within the authorized time period and satisfies the time rule, otherwise it does not satisfy it. For example, if t start =8×60=480 (corresponding to 8:00 in the morning), t end =18×60=1080 (corresponding to 6:00 p.m.), current time t current =1000 (the number of minutes converted to a certain time point). Since 480≤1000≤1080, the travel time rule for the vehicle is met.

[0015] In a possible implementation, the barrier state monitoring in S4 includes motor current monitoring and barrier pole position monitoring.

[0016] In a possible implementation, the motor current detection is performed by the following algorithm:

[0017] Assume that the normal operating current range of the motor is [I min ,I max ], the motor current monitored in real time is I current , when I current min or I current >I max ​When the motor is abnormal, it is determined that the motor is running abnormally and a fault warning is triggered. For example, the normal operating current range of the motor of a gate control device is set to [2A, 5A]. If the motor current I is monitored in real time current =6A. Since 6A>5A, it is judged that the motor is overloaded or in other abnormal conditions, and corresponding alarm prompts and subsequent processing are required.

[0018] In a possible implementation, the barrier pole position detection is performed by the following algorithm:

[0019] Assume that the standard angle of the gate rod when it is fully opened is θ open (e.g. 90°), the allowable angle deviation is Δθ, and the actual monitored gate pole angle is θ actual , when |θ actual -θ open |>Δθ, the barrier pole position is judged to be abnormal, for example, the barrier pole is fully opened to the standard angle θ open =90°, the allowable angle deviation Δθ=5°, the actual monitored gate pole angle θ actual =80°, calculate |θ actual -θ open |= | 80°-90° | =10°, because 10°>5°, it is determined that the barrier pole position is abnormal and an early warning message is issued.

[0020] A barrier gate control opening system based on the Internet of Things includes an Internet of Things cloud platform, a barrier gate control device, a communication module, a vehicle detection sensor and a user terminal.

[0021] In a possible implementation, a license plate recognition camera is installed on the gate control device.

[0022] Compared with the prior art, the present invention has at least the following beneficial effects:

[0023] First, by double-verifying the vehicle's license plate and authorization time, the vehicle's identity authentication is more accurate, thereby improving security. In addition, through the user terminal, users can remotely operate the gate anytime and anywhere, greatly improving management efficiency and reducing personnel travel;

[0024] Second, by monitoring the barrier during its operation, the barrier control equipment can feed back its own status information to the cloud platform in real time. When an abnormal state occurs, the cloud platform can issue an alarm notification in time, facilitating rapid maintenance and other response measures. BRIEF DESCRIPTION OF THE DRAWINGS

[0034] Example 1

[0035] like Figure 1 As shown, an embodiment of the present invention provides a gate control opening method based on the Internet of Things, comprising the following steps:

[0036] S1, the vehicle arrives at the detection point of the vehicle detection sensor;

[0037] S2, the license plate recognition camera verifies the vehicle's license plate and authorization time. License plate verification is divided into local verification and remote verification. Local verification is when the vehicle arrives at the detection point, the camera automatically captures the license plate image, and then extracts the license plate number through the built-in image recognition algorithm, and compares it with the locally pre-stored authorized license plate number list. If the match is successful, the verification is successful. Remote verification is after the vehicle arrives at the detection point, the communication module uploads the vehicle arrival information to the cloud platform, and the cloud platform sends the license plate information to the background permission management system for verification. The background system queries the corresponding authorization record in the database. If the vehicle has the right to pass, the verification is successful. After the license plate verification is successful, the authorization time is verified. Assume that the vehicle's authorized passage time period is 8:00-18:00, and the current time is 15:30. Convert the time into minutes, 480≤930≤1080, and the verification is successful;

[0038] S3, after the license plate verification and authorization time verification are passed, the IoT cloud platform transmits the signal to the gate control device through the communication module, and the gate is opened;

[0039] S4, during the gate opening process, the gate control device will feed back its own status information to the IoT cloud platform through the communication module in real time. The status information includes the motor current and the gate pole position. When monitoring the motor current, the normal operating current range of the motor is set to 2A-5A. When the motor current is detected to be 5.2A in real time, the motor is overloaded. When monitoring the gate pole position, the standard angle of the gate pole when fully opened is set to 90°, and the allowable deviation angle is 5°. When the gate pole angle is monitored to be 75° in real time, the gate pole position is abnormal, and the gate control device will feed back the fault information to the IoT platform through the communication module.
