Description

Technical Field

[0001] The present application relates to the technical field of non-stop weighing, and in particular to a method, device and equipment for dynamic weighing of large-piece transportation suitable for high-speed entrances and exits. Background Art

[0002] With the development of logistics and transportation industry, the number of large-scale transport vehicles is increasing. Traditional fixed weighing systems are difficult to meet the diverse vehicle traffic needs. Existing highway toll stations usually adopt fixed lane layouts and cannot flexibly respond to different types of vehicles, especially large-scale transport vehicles. When large-scale transport vehicles pass through, due to the limited lane width, it is easy to cause traffic congestion and safety hazards.

[0003] In addition, existing weighing systems are usually fixed weighing systems, which usually have only one set of weighing sensors. For different types of vehicles, especially large vehicles, the weighing data may not be accurate enough. For example, the different wheelbases and weight distributions of vehicles will affect the accuracy of the weighing results.

[0004] The existing weighing system also lacks flexibility. The traditional weighing system cannot be dynamically adjusted according to different vehicle types and cannot flexibly cope with vehicles of different sizes and weights. This not only affects the accuracy of weighing, but also reduces the overall traffic efficiency. Summary of the invention

[0091] Identify the information of passing vehicles. Before the passing vehicles enter the weighing lane 1, the staff confirms the type of passing vehicles (large-scale transport vehicles or ordinary vehicles). The laser vehicle separator 5 emits a laser beam to detect the outline and position of the passing vehicles. The image acquisition device 4 captures the image of the passing vehicles through the camera. The recognition device processes the image data and determines the driving status of the passing vehicles in the weighing lane 1.

The toll booth staff charges according to the weighing data. After the charging is completed, the weighing lane 1 gate is opened, and the vehicle passes through the toll station, completing the entire weighing and charging process.

[0096] 6) Second use state: ordinary vehicles pass. When the passing vehicle is identified as an ordinary vehicle, the weighing meter 3 switches to the second use state.

[0097] 61) Arrange "isolation component 2" to separate the weighing lane 1 into the first lane and the second lane.

[0098] 62) The weighing meter 3 processes the weighing data of ordinary vehicles, and the weighing sensor 6 collects the vehicle weight data. The weighing meter 3 receives and processes the data from the weighing sensor 6, calculates the vehicle weight of the first lane and the second lane respectively, and displays the vehicle weight of each lane through the weighing display 7, and sends the data to the toll booth and the cloud storage; the toll booth staff or the ETC system charges according to the weighing data; MTC lane: the toll booth staff controls the opening and closing of the gate; ETC lane: the remote control system controls the opening and closing of the gate; the vehicle passes through the toll station to complete the entire weighing and charging process.

[0099] 7) Cloud storage: All weighing data are processed by the weighing instrument 3 and uploaded to the cloud storage, which stores the weighing data for subsequent analysis, statistics and tracing.
