Road safety & law following, using vehicle load monitoring system
Project Area of Specialization
Project Summary
At present, there are the two mainly methods to measure vehicle load:static measuring and dynamic measuring. The regular vehicle detecting station, one of static measuring methods, is simple but also get a accurate result, which is commonly knows as truck scales[1]. The ruck scales demands vehicle to be at some fixed point, and measures inefficient. Dynamic measuring is able to measure load information of the vehicle in real time, among which, technology of monitoring system for vehicle overloading based on paste-type strain sensor is the maturational one. The system used paste-type strain sensor that installed in vehicle leaf spring to obtain load on the leaf spring[2]. But the disadvantage of the system is the damage of the vehicle-bridge, because the paste-type strain gauge must be installed in vehicle leaf. In addition,investigating different vehicle-bridges physical form, finding the correct situation for the sensor and load calibration according to the test, the system is not universal. Analyzing the method mentioned above, the vehicle load measuring contradiction is between the accuracy of the static measuring and convenience of the dynamic measuring[3], so, it come to method of vehicle load monitoring system based on ultrasonic sensors.
Project Objectives
Overloading the impact on traffic safety, measuring the deformation of leaf spring form the start, a vehicle load measuring system was designed based on ultrasonic sensors. In this article, the mathematics model of steel plate deformation and load is discussed upon the mechanics principle and obtain the relationship of load and deformation. Processing the data that the ultrasonic sensors measured by single-chip and using temperature sensor to compensate, it comes to the result of vehicle load.According to the test, the system achieved the purpose of real time measurement of vehicle load, and it is useful.
Project Implementation Method
Overall scheme of the system. Between car body and axle, there is a leaf spring, which offers good performance for shock absorption. When the vehicle is under load, tire will be deformed under the force of stress. As a result, the distance between the vehicle-bridges and ground will be shorter. The ultrasonic sensors is installed in vehicle suspension, using the time that ultrasonic from lunch to return to obtain the distance between the vehicle-bridges and ground, combining with the information of each sensors, computes the load of the vehicle.
Benefits of the Project
when boom amplitude limit close to work, work when lifting load and torque device close to the permitted load limit, the system output torque control signal to stop the crane continue to continue to run in the direction of risk, allow crane moves in the direction of security.
• can keep the van safe from accidents
• help the operator to verify all the necessary parameters to work in the right and practical way
