Enviko Quartz-based Weigh-In-Motion (WIM) Enforcement System

 Enviko Quartz-based Weigh-In-Motion (WIM) Enforcement System


System Overview
The non-stop weighing enforcement system primarily provides business application functions for fixed roadside overloading detection stations. It mainly adopts non-contact enforcement methods, relying on pre-inspection equipment to complete the detection and weighing of cargo transport vehicles. The system can publish overloading information and blacklist data through variable message boards, and it manages the business processes digitally via the software of the fixed roadside overloading detection station.

Typical Layout

Function Description

  • For vehicles passing through the main highway lane, the weighing system can automatically detect the vehicle's total weight, axle weight, number of axles and tires, axle distance, vehicle speed, and vehicle acceleration.
  • The system can accurately and effectively separate vehicles and handle abnormal driving conditions such as vehicle queuing and lane changing, ensuring the correspondence between vehicles and data.
  • The system has an automatic buffering function, allowing it to store a certain amount of data. If the data transmission to the roadside overloading computer fails, the system can resend the data, ensuring data uniqueness and integrity.
  • Weighing information can be transmitted to the backend control computer through a defined data interface.
  • The system has a fault self-diagnosis function, and when any equipment or line failure occurs, the system can obtain corresponding fault information.
  • The system can meet the needs of uninterrupted, continuous, and all-weather operation in an unattended mode.
  • For semi-trailer vehicles with inconsistent front and rear license plates, the system adds rear vehicle capture equipment to capture both the front license plate and the trailer plate.
  • The system can capture two panoramic feature images of overloaded vehicles (including the full view of the vehicle, license plate, color, model, and prominent geographical features).

System Components
The non-stop weighing enforcement system consists of a dynamic high-speed weighing system, vehicle separation system, vehicle recognition system, roadside video surveillance system, roadside information release system, and roadside information integration transmission system.

Improved Installation Scheme for Piezoelectric Quartz Weighing Sensors on Asphalt Pavement

Image
  1. Background Technology   Currently, WIM systems based on piezoelectric quartz weighing sensors are widely used in projects such as overload monitoring for bridges and culverts, non-site overload enforcement for highway freight vehicles, and technological overload control. However, to ensure accuracy and service life, such projects require cement concrete pavement reconstruction for the piezoelectric quartz weighing sensor installation area with the current technology level. But in some application environments, such as bridge decks or urban trunk roads with heavy traffic pressure (where the cement curing time is too long, making long-term road closures difficult), such projects are difficult to implement.   The reason piezoelectric quartz weighing sensors cannot be directly installed on flexible pavement is: As shown in Figure 1, when the wheel (especially under heavy load) travels on the flexible pavement, the road surface will have a relatively large subsidence. However, when rea

Enviko Quartz Sensor for Weigh-In-Motion System

Image
  In recent years, overloaded and oversized transportation of road freight vehicles has become a serious problem threatening road traffic safety nationwide. Weigh-In-Motion (WIM) systems are currently the most widely used and effective measure to govern overloaded and oversized transportation on highways. Quartz Weighing Systems are internationally leading Weigh-In-Motion (WIM) systems. Their core component is the quartz sensor, which is made from specially processed quartz crystals. Quartz sensors have no mechanical parts and are maintenance-free. After installation, they are embedded in the road surface and have a long service life (no failure within 10 years) and an IP68 protection rating. Here are the features of the quartz sensors developed by Enviko: (1) With the quartz crystal as its "heart", the quartz sensor has perfect linear output, consistent repeatability of weighing output signal, high system integration, weighing preparation, high degree of automation, stable
