Highway Dynamic Axle Load Scale

What Is Highway Dynamic Axle Load Scale?

The standard configuration consists of a scale body (including weighing sensors, junction boxes, limit kits, embedded parts, etc.) and weighing instruments. Other external devices can be purchased according to different user needs to form various configurations, including computers, printers, large screen displays, power surge protectors, voltage stabilizing power supplies, multi-functional power sockets, and closing devices (vehicle detectors, photoelectric switches).

The weighing platform is sturdy and highly integrated. Select stable and reliable high-precision alloy steel bridge type weighing sensors and intelligent dynamic and static weighing display instruments. The weighing data can be printed and recorded by a printer through the standard interface of the instrument, connected to a large screen display to display the weighing data, or connected to a computer to form a weighing management system.

1. Mechanical Weighing Table

• The entire scale consists of a 3.8 * 0.9m long rectangular scale surface with a profile frame structure and seamless laser welding. The weighing platform is sturdy and highly integrated.
• The mechanical weighing platform serves as a support and force transmission mechanism, consisting of a weighing platform, a digital axis device, a sensor pressure head, a longitudinal limit, a transverse limit, a base, and a foundation-embedded plate, to complete the guidance, support, and force transmission work of the measuring process.
• The weighing platform is the main part of the Highway Dynamic Axle Loadscale, welded from section steel and steel plates, with sufficient strength, stiffness, and good stability. The weighing platform is installed on the foundation embedded parts through sensors.
• The sensor pressure head is the connection between the sensor and the weighing platform, and its function is to ensure that the sensor is in good stress state.
• The function of the base is to support the weighing sensor and limit system, and it is welded and fixed with the foundation-embedded plate.
• The embedded plate is embedded in the reinforced concrete foundation as a base support.

2. Sensor System

The sensor system consists of a set of weighing sensors and a junction box, and the sensors are connected in full parallel. The axle group dynamic scale uses four sensors, which are connected to the weighing display through a junction box and adjust the balance of the four corners of the scale.

3. Axle Recognizer

Single-axle and multi-axle metering can automatically identify the axle type and wheels of a vehicle.

4. Infrared vehicle separator

It can automatically determine whether the vehicle has passed through, thereby accurately determining the weight of the entire vehicle.

5. Weighing display

It is the core component of the vehicle dynamic scale, used to display and print weighing results, and has very complete Chinese character printing and statistical functions.

Business process description:

1. Initial state: There are no vehicles in the detection area.
2. When the cargo vehicle enters the station, on-site personnel guide the vehicle to drive at low speed to the weighing platform for inspection.
3. The vehicle triggers a precise axle splitting subsystem and intelligent high-definition vehicle license plate subsystem, and the license plate recognition camera captures the license plate image and automatically recognizes the license plate number; At the same time, the precise combination of the axle subsystem and the weighing subsystem detects the relevant information of the vehicle, including the number of axles, axle weight, vehicle type, total weight, and speed.
4. When the overrun vehicle detection system collects information about the vehicle’s axle weight, total weight, speed, and license plate, it automatically determines the number of axles, vehicle type, and overrun situation based on the threshold of the overrun penalty standard. The vehicle information, such as license plate number, total weight, overweight, overrun rate, and amount, is sent to the information display subsystem for display and sound and light alarm, prompting drivers and overload control personnel. Vehicles that have not exceeded the limit shall be directly released, and vehicles that exceed the limit shall be compensated, fined, or unloaded according to the standard threshold before being released or re-inspected.

Features of Highway Dynamic Axle Load Scale

• Adopting a modular structural system, easy installation and maintenance
• Adopting axis measurement method, small scale area, lightweight, small civil engineering quantity, convenient installation, and maintaining level ground
• Static weighing, stable performance, and high accuracy
• Dynamic weighing, vehicle mass that can be weighed without parking

Function of Highway Dynamic Axle Load Scale

1. Automatic closing discrimination (can be manually distinguished)
2. Storage and printing of data
3. Automatic vehicle classification/types (such as 2-axis, 3-axis, etc.), and allow additional types of password protection from regulatory levels when needed.
4. Data processing functions:

• Weighing date and time.
• Vehicle speed during weighing.
• Accurate single axis and group weights and their speeds.
• Accurate total vehicle weight.
• Automatically calculate overload penalties according to instructions (load limits and penalty rates should be edited from the supervisor level when password protection is required).
