Different Types of Overload Weighing Systems for Trucks on Highways

On January 1, 2020, nationwide expressways implemented weighing at entrances and a policy of persuading overloaded trucks to turn back or prohibiting them from entering. This effectively prevented overloaded vehicles from driving on expressways, curbing the rampant phenomenon of truck overloading. However, driven by interests, the chaos of overloading was not completely eliminated. Overloaded vehicles that were rejected from expressways surged onto national highways, provincial roads, and county roads, posing huge safety hazards. As a result, relevant local departments began to carry out special rectifications. Dynamic road vehicle automatic weighing systems achieved a leap from traditional to technological overload control, greatly reducing the workload of overload control, and were widely applied to various overload control sites, playing an important role in cracking down on illegally overloaded vehicles. The mainstream technologies for dynamic road vehicle automatic weighing systems are the bending plate (narrow strip) type, modular flat plate type, and quartz crystal type. This article provides detailed introductions to the definitions, principles, structures, and characteristics of these three types of dynamic road vehicle automatic weighing systems, in hopes that this knowledge will help everyone in selecting, using, and maintaining them.

Improved Installation Scheme for Piezoelectric Quartz Weighing Sensors on Asphalt Pavement

  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

Quartz Weighing Sensor Reliability Testing Technology for WIM systems

  Overloading and exceeding limits of highway vehicles cause significant damage to road surfaces and pose a high risk of safety accidents, a particularly serious issue in our country where 70% of road safety incidents are attributed to vehicle overloading and exceeding limits. This results in direct economic losses of nearly 3 billion RMB, with losses from vehicle overloading and exceeding limits on highways exceeding 30 billion RMB annually. Hence, it's critically important to monitor and supervise overloaded vehicles on highways. In order to regulate vehicle overloading without disrupting traffic, the Weighting In Moving (WIM) highway dynamic weighing scheme has emerged. This system utilizes piezoelectric quartz sensors to quickly measure vehicle weight as vehicles pass over the road surface at high speeds (<120km/h) and trigger monitoring cameras for photographing. Enviko quartz sensors are specially designed for low-cost, high-performance piezoelectric quartz sensors for hig

Key Design of Direct Enforcement Inspection Stations for Road Overload Control

1. Introduction Illegal overloading and overloading of trucks not only destroys highways and bridge facilities, but also easily causes road traffic accidents and endangers the safety of people's lives and property. According to statistics, more than 80% of road traffic accidents caused by trucks are related to oversized and overloaded transportation. The traditional overrun and overloaded transportation checkpoint mode has low law enforcement efficiency, which is easy to cause the phenomenon of overrun vehicle omission, and the direct enforcement detection point control mode relies on the dynamic automatic weighing and detection system to automatically detect, identify and screen the passing vehicles around the clock, so as to achieve accurate and efficient control of overrun and overloaded vehicles. In order to strengthen the governance of overloaded transportation behavior, ensure the safety of highway facilities and people's lives and property, the direct enforcement sys
