Projects are underway simultaneously in Zhangjiakou, Heyuan, Dazhou, with construction progressing rapidly.

GOOD NEWS: Recently, we have won bids for multiple weighing projects and off-site enforcement projects across China. Several projects are underway simultaneously in Zhangjiakou, Hebei Province; Heyuan, Guangdong Province; Dazhou, Sichuan Province; and Bozhou, Anhui Province, with construction progressing rapidly. The off-site enforcement system, independently developed by Hengliang Tech, is primarily used on multi-lane highways such as national and provincial roads. When vehicles pass through the weighing area under normal driving conditions, the system can directly identify the vehicle's license plate, dimensions, model, number of axles, axle load, and overload status, simultaneously transmitting this information to the weighing center for direct enforcement. This system mainly comprises several subsystems, including a weighing subsystem, an ALPR subsystem, a variable information system, a vehicle size recognition system, a storage system, and a platform software system. These systems work together seamlessly and are compatible with each other to achieve direct enforcement.   话题标签#weighingsystem 话题标签#VMSsystem 话题标签#HengliangTech

Introduction of the Quartz Dynamic Truck Scale System

The dynamic vehicle weighing system is a dynamic weighing system with quartz weighing sensor as the core part, charge amplifier, weighing processor, industrial computer as the main accessories, and ground sensor coil as the auxiliary accessories. The system installs vehicle weighing equipment on highways, national roads, provincial roads etc. to collect weight data and other basic data information of vehicles in motion (such as: number of vehicles, wheelbase, vehicle type, traffic volume, etc.), realize data upload processing, and achieve overload control purpose. This system can also accurately calculate vehicles driving at various speeds, and can effectively solve the influence of speed on weighing accuracy. Compared with traditional weighing platforms, it has the advantages of strong anti-interference ability, short construction period, convenient maintenance, and not easily affected by weather conditions.

Influencing factors of dynamic weighing system

Based on the weighing principle of the truck scale, the main factors affecting the weighing results are: 1. Sensor Weighing sensor is a sensitive device that converts pressure into an electrical signal. The measurement accuracy and dynamic responsiveness of the sensor can directly affect the accuracy of the final result. The errors introduced from the sensor include repeatability error, creep, temperature error, etc. Therefore, the sensor must have both high sensitivity and good reusability. 2. Weighing Instruments Weighing instruments are electronic devices, and their normal operation will be subject to many interferences, such as power supply fluctuations and temperature. The errors caused by electronic instruments include comprehensive effects (nonlinearity, hysteresis, and the influence of temperature on the range), the influence of temperature on the no-load indication, power supply changes, and range stability. 3. The flatness and inclination of the road surface The flatness and inclination of the road surface affect the force on the weighing sensor, so that the truck does not apply force perpendicular to the scale plane, which in turn affects the weighing result. Generally, when installing, pay attention to choosing a flat foundation to ensure that the sensor and the scale platform are in good contact and each sensor is relatively evenly stressed. 4. Vehicle speed The standard stipulates that vehicles should pass at a speed between the maximum speed and the minimum speed. The higher the speed, the further the vehicle axle weight signal deviates from the true value. In addition, changes in vehicle speed will cause the vehicle itself to vibrate, adding a lot of interference to the weighing process. 5. Vehicle status Various abnormal driving conditions in the weighing area, such as terminal pressing, S-bend, stop-and-go, and reversing, will cause a large deviation between the vehicle weight and the actual weight.

Preventive maintenance can extend the life of weighing sensors

After-sales service and maintenance are important links for companies to maintain long-term relationships with customers. High-quality after-sales service can not only improve customer satisfaction, but also enhance brand loyalty. In addition to normal installation and commissioning, fault repair, regular maintenance is also very important.Hengliang Tech has a professional technical support team that can provide 7*24 hours of after-sales service. In addition, regular return visits and regular maintenance are also the top priorities in their work: There is an old Chinese saying that prevention is better than cure. Preventive maintenance can extend the life of equipment, reduce sudden failures, and ensure the normal operation of the weighing system.

Direct enforcement is an effective means of technological control of overweight vehicles

Direct enforcement is an effective means of technological control of overweight vehicles. The system is mainly composed of a dynamic weighing subsystem, an intelligent license plate recognition subsystem, an information release subsystem, an information notification subsystem, an outer dimension detection subsystem, a matching upload subsystem, a management platform subsystem, and a monitoring command center subsystem. A flat plate or quartz weighing system can be used according to factors such as the use environment, traffic impact, basic road conditions, and economy. The quartz dynamic weighing system consists of quartz weighing sensors, charge amplifier, high-speed vehicle separator, weighing processor, road structural adhesive, an electrical cabinet, etc. It performs high-speed, high-density, and high-precision data sampling on the moving vehicle, and then accurately calculates a series of information such as the speed, axle weight, and wheelbase of the moving vehicle. The sensor and foundation requirements are slightly higher, but with good stability, long lifespan, and the high comprehensive performance. Due to the high dynamic response and low temperature sensitivity of quartz crystal weighing sensors, the accuracy is more stable than other types in high-speed dynamic weighing occasions and areas with large temperature differences. At the same time, the installation method of the sensor and the foundation tightly fits to prevent sand blockage and freezing failures, and has a stable advantage in areas such as high-cold deserts. The flat-plate weighing system consists of a flat-plate weighing body, a signal amplifier, a weighing display, and a vehicle separation device. Its road weighing device includes a weighing body, a weighing sensor, and a weighing load frame for supporting the weighing load, etc. It adopts a full steel, fixed structure. It is designed and installed in an integrated manner with the foundation, and has the characteristics of strong bearing capacity, large detection area, not easy to cheat, and high weighing accuracy. The flat-plate weighing system is quick to construct and has a low impact on traffic. The self-developed anti-shear weighing sensor and multi-channel independent sampling algorithm, anti-cheating and multi-lane merging algorithm make the product have the same detection accuracy and stability in most use occasions, while having the advantages of rapid construction and cost.
