Automatic Overload Detection System

      Highway weighing is a very important technology, mainly used to calculate the weight of vehicles and detect overloaded vehicles. The working principle of highway weighing is to measure the pressure changes between the vehicle tires and the ground through multiple weighing sensors, and then calculate the total weight of the vehicle.

      When the vehicle passes by the weighing sensor, the sensor will sense the pressure changes of the wheels through the pressure sensor and transmit these data to the control center through the transmission line. Next, the control center will calculate these data and determine the total weight of the vehicle, in order to identify overloaded vehicles or quantitatively measure the weight of vehicles.

2: The working mode of load cells

      Highway dynamic weighing system mainly measures the weight of vehicles through sensors. Most loads now use the piezoelectric effect for measurement.

      In sensors, they are mainly divided into two parts: signal processing circuits and pressure sensors. The signal processing circuit is used to receive the output signal of the pressure sensor and convert it into a digital signal through digital to analog conversion. The pressure sensor measures the pressure changes of the wheel through the piezoelectric effect, and then converts it into an electrical signal to output to the signal processing circuit.

3: Application of dynamic weighing system:

      In recent years, with the large-scale construction of overload detection stations and highway Automatic overload Detection System and toll collection systems by the transportation department, the domestic dynamic weighing system product industry has gained significant historical opportunities. However, due to the relatively sudden large-scale application of the above-mentioned projects, the time for the original manufacturers to improve and enhance their product technology level was clearly insufficient. In order to complete the contract on schedule, the manufacturers had to invest a large amount or even all of their manpower and resources into the sudden arrival of engineering projects. Due to the continuous expansion of market demand, a large number of non professional new enterprises blindly launch and follow up hastily, resulting in a mixed bag of related products in the dynamic weighing industry and uneven product quality, which poses great hidden dangers for customers' later use and maintenance. If this situation is not corrected, in two or three years, some system equipment will be scrapped in advance, and customers will have to spend huge investments to reinstall the equipment. Therefore, the application of high-speed Automatic Overload Detection System is very promising.

4: Summary

      Highway Automatic Overload Detection System is a very practical technology, thanks to which we can better ensure the safety and normal operation of highways. This technology measures the weight of vehicles through multiple sensors, achieving measurement and overload detection of vehicles. With the help of sensors, we can calculate the weight of vehicles more accurately, improving the safety and efficiency of road transportation.
