Description

Technical Field

[0001] The present invention and the field of traffic engineering technology specifically relates to a dynamic weighing system deployment method suitable for high-speed entrances and exits. Background Art

[0002] With the development of logistics and transportation industry, the number of large freight vehicles is increasing. Traditional fixed weighing systems are difficult to meet the diverse traffic needs of vehicles. Existing highway toll stations usually adopt fixed lane layouts and cannot flexibly respond to different types of vehicles, especially large transport vehicles. When large 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

The "connection" and "coupling" mentioned in this application, unless otherwise specified, include direct and indirect connections (couplings).

[0058] See also Figure 1-Figure 4 The present application provides a new technical solution: a method for deploying a dynamic weighing system suitable for high-speed entrances and exits, the method comprising the following steps:

[0059] Step S101, providing at least one weighing lane 1, wherein the weighing lane 1 is arranged at an entrance or exit of a highway and is used to weigh vehicles passing through the entrance or exit of the highway; the weighing lane 1 has two use states, and the two sets of use states are switched according to different passing vehicles, and the weighing lane 1 switches between the two use states through an isolation component 2.

[0060] In some embodiments, the weighing lane 1 is formed by newly constructing or removing at least one toll island at the entrance or exit of the highway, and its width is sufficient to accommodate the safe passage of large-scale transport vehicles. The weighing lane 1 is switched between the two usage states through the isolation component 2; the two usage states include:

[0061] The first use state: the isolation assembly 2 on the weighing lane 1 is evacuated, and the weighing lane 1 allows large-scale transport vehicles to pass;

[0062] Second use state: the isolation component 2 is arranged in the weighing lane 1 to separate the weighing lane 1 into a first lane and a second lane, and both the first lane and the second lane allow ordinary vehicles to pass through;

[0063] The two groups of usage states correspond to the calculation rules of the usage states respectively.

[0064] In some embodiments, the weighing lane 1 includes at least two weighing units, which are respectively arranged in the first lane and the second lane, and are used to weigh and detect vehicles passing through the weighing lane 1;

[0065] The weighing unit includes at least two groups of weighing sensors 6, the two groups of weighing sensors 6 are perpendicular to the driving direction of the vehicle in the first lane or the second lane, the two groups of weighing sensors 6 are arranged in parallel in the first lane or the second lane, and the two groups of weighing sensors 6 arranged in parallel cover both sides of the first lane or the second lane;

[0066] The weighing sensors 6 are arranged in parallel on the first lane and the second lane, and at least one row of weighing sensors 6 is arranged on the first lane and the second lane.

[0067] Step S102: When a passing vehicle enters the weighing lane 1, the passing vehicle information is identified.

[0068] In some embodiments, the identification device includes a laser vehicle separation device 5 and an image acquisition device 4. The laser vehicle separation device 5 detects the outline and position of the vehicle by emitting a laser beam. The detected vehicle information is used to distinguish different vehicles. When a vehicle enters, the weighing meter 3 is notified that a vehicle has entered and weighing begins. When a vehicle exits, the weighing meter 3 is notified that the vehicle has exited, and the total weight can be settled. The image acquisition device 4 captures the image of the vehicle through a camera. The image acquisition device collects the information of the vehicle and generates data such as the front, body, rear, and passing video of the vehicle for archiving, law enforcement, and other operations, and is used to separate vehicles and obtain vehicle image data.

[0069] The staff confirms whether the passing vehicle is a large-cargo transport vehicle; if so, the isolation component 2 on the weighing lane 1 is removed, so that the weighing lane 1 is in the first use state; if not, the isolation component 2 is set in the weighing lane 1 to separate the weighing lane 1 into a first lane and a second lane, and both the first lane and the second lane allow ordinary vehicles to pass, so that the weighing lane 1 is in the second use state;

[0070] In normal use, the lane defaults to the second use state;

[0071] The isolation component 2 is at least one or a combination of elastic columns or traffic cones, and is arranged along the traffic markings in the weighing lane 1.

[0072] Step S103: matching the use status of the weighing lane 1 according to the passing vehicle information, and switching the weighing lane 1 to the corresponding use status.

[0073] In some embodiments, the use state is switched by a weighing meter 3;

[0074] The weighing instrument 3 is provided with an LCD interactive screen, and the LCD interactive screen or the network protocol is switched. The LCD interactive screen supports entering the weighing use state switching mode through password verification, and switches the two use states of the weighing lane 1;

[0075] The weighing instrument 3 is also provided with a network interface, which supports connection with an external network and remotely switches the two use states of the weighing lane 1 through a preset network protocol.

[0076] Step S104: Calculate the weight data of the passing vehicles based on the calculation rules corresponding to the use status of the passing vehicles.

[0077] In some embodiments, when the passing vehicle is identified as a large-scale transport vehicle, the weighing lane 1 is switched to the first use state, and the calculation rules corresponding to the first use state are as follows:

[0078] The weight data of the heavy-duty transport vehicle is calculated based on the axle weight. The axle weight of the heavy-duty transport vehicle is the sum of the weighing data on the two sets of weighing units. The total weight of the heavy-duty transport vehicle is the sum of the actual weights of all axles.

[0079] Furthermore, the calculated axle weight of the heavy-duty transport vehicle is the original weight, which needs to be corrected and further calculated according to parameters such as axle weight coefficient and speed coefficient to obtain the real weight. The weighing instrument 3 will display the real weight and number of axles of each axle of the heavy-duty transport vehicle in real time. The real weight error of the axle of the heavy-duty transport vehicle is within a certain range (±5%), and the total weight of the heavy-duty transport vehicle does not need to be further calculated by parameters such as total weight coefficient and speed coefficient. The real weight error of the axle of the heavy-duty transport vehicle and the total weight error are within the same range (±5%).

[0080] When the passing vehicle is an ordinary vehicle, the weighing lane 1 is switched to the second use state. The weighing lane 1 is separated into a first lane and a second lane by the isolation component 2. Both the first lane and the second lane can pass ordinary vehicles. The calculation rules corresponding to the second use state are as follows:

[0081] The weight data of the first lane or the second lane are respectively the weighing data of the weighing sensor 6 on the weighing unit on the first lane or the second lane;

[0082] Furthermore, the processing of weighing data on the first lane and the second lane follows a unified principle. The actual total weight of the vehicle on the lane is the product or correction value of the measured total weight and parameters such as the total weight coefficient, speed coefficient, and position coefficient. The total weight error of a normal lane is less than the axle weight error, total weight error (±5%), and axle weight error (±10%).

[0083] In this embodiment, both the first lane and the second lane can be configured as MTC or ETC lanes;

[0084] When the first lane or the second lane is configured as an MTC lane, the weighing unit on the first lane or the second lane weighs and detects the vehicles passing through the first lane or the second lane, and the weighing data is processed by the weighing instrument 3 and transmitted to the toll booth or the cloud server, and the toll booth staff controls the opening and closing of the MTC lane gate;

[0085] When the first lane or the second lane is configured as an ETC lane, the weighing unit on the first lane or the second lane weighs and detects the vehicles passing through the first lane or the second lane. The weighing data is processed by the weighing instrument 3 and then transmitted to the toll booth or the cloud server. The toll collection system automatically controls the opening and closing of the ETC lane gate according to the vehicle overload rate.

[0086] Step S105: The weight data calculated based on the passing vehicle is processed by the weighing meter 3, and the processed data is sent to the corresponding receiving unit.

[0087] In some embodiments, the data of the weighing sensor 6 on the weighing unit is processed by the weighing instrument 3, and the processed weighing data is sent to the corresponding receiving unit and displayed;

[0088] In the first use state, the data of the weighing sensors 6 on the two weighing units are transmitted to the weighing meter 3, and the weighing meter 3 collects the data of all the weighing sensors, performs fusion analysis on the weighing data, and calculates the weight, speed and position information of the vehicle according to the state information of the weighing sensors. After the vehicle leaves, the weight data of the large-scale transport vehicle is calculated and the weight data is transmitted to the weighing display screen 7 for display;

[0089] In the second use state, when the first lane or the second lane is configured as an MTC lane, the weighing unit on the first lane or the second lane weighs and detects the vehicles passing on the first lane or the second lane, processes the weighing data through the weighing meter 3, and transmits the weighing data to the corresponding weighing display screen 7 for display;

[0090] When the first lane or the second lane is configured as an ETC lane, the weighing unit on the first lane or the second lane weighs and detects the vehicles passing through the first lane or the second lane, processes the weighing data through the weighing meter 3, and transmits the weighing data to the corresponding weighing display screen for display;

[0091] The data processed by the weighing instrument 3 are uploaded to the cloud storage, and the weighing data are stored in the cloud storage for subsequent analysis, statistics and tracing.

[0096] 2) A dynamic weighing device is set up on the weighing lane 1. The dynamic weighing device includes a weighing sensor 6, an isolation component 2, a laser vehicle separator 5, an image acquisition device 4 and a weighing meter 3. The weighing meter 3 is provided with an LCD interactive screen and a network interface. All devices are connected through RS485 or RS232 communication cables, and preliminary tests are carried out to ensure that the device can work normally.

[0097] 3) 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 separation device 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.

[0098] 4) Switch the use status of weighing lane 1. According to the identified passing vehicle information, the switching operation can be performed through the LCD interactive screen or network protocol on the weighing instrument 3, supporting password verification and remote control, and the control system switches weighing lane 1 to the corresponding state.

[0099] 5) First use state: Large-cargo transport vehicles pass. When the passing vehicle is identified as a large-cargo transport vehicle, the weighing meter 3 switches to the first use state.

[0100] 51) Remove the “isolation component 2” to put the weighing lane 1 in the first use state.

[0101] 52) The weighing meter 3 processes the weighing data of the large-scale transport vehicle, 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 total weight of the large-scale transport vehicle (the sum of the data of the weighing sensors 6 on the two sets of weighing units), and the weighing display 7 displays the total weight of the large-scale transport vehicle, and sends the data to the toll booth and the cloud storage. 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.

[0102] 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.

[0105] 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.

[0106] 8) System reset: After the vehicle has completely passed, the system is reset and a new isolation component 2 is set up to prepare for the next vehicle.
