Dynamic motor truck scale and method for testing truck weight

Abstract

The invention discloses a dynamic motor truck scale and a method for testing truck weight, specially fitted for testing the truck weight under the dynamic condition. The inaccurate testing exists in the prior art. The dynamic motor truck scale of the invention comprises a grating sensor, a wheel axle identifier and an image collector which are arranged by matching with a weighting platform, wherein a transmitter and a receiver of the grating sensor are respectively arranged on two sides of a weighting channel in front of the weighting platform; the wheel axle identifier is arranged on the weighting channel in front of the weighting platform; the grating sensor, the wheel axle identifier and the image collector are all connected with a data collecting device. The data collecting device sums the weight data of each sensed wheel axle, analyzes and calculates the running speed and the acceleration of the truck according to the collected images, and verifies the weighting data so as to acquire the gross truck weight. The testing is accurate, the testing error which occurs due to the speed change in the testing points is prevented and the cheating phenomenon is avoided.

Description

【Technical field】 [0001] The invention relates to a vehicle weight measurement tool and method, especially suitable for vehicle weight measurement under dynamic conditions. 【Background technique】 [0002] With the rapid development of my country's national economy, the rapid growth of road traffic has put forward higher requirements for the efficiency of road supervision. The traditional static weighing method can no longer meet the needs of existing road inspections. Road administration urgently needs an accurate, low-cost The advanced vehicle dynamic weighing system can efficiently monitor and judge whether there is an over-limit transportation state of road transport vehicles. [0003] Existing dynamic truck scales, as described in the Chinese patent No. 200320127306.0, mainly include a scale body, a data acquisition control device and functional detection components. Hall sensor devices used to detect vehicle speed, wheelbase and number of tires, load cells used to detec...

Problems solved by technology

But in actual operation, strict uniform velocity does not exist

When the vehicle is accelerating, the front axle will "become lighter" and the rear axle will be "heavier". In the case of deceleration, the opposite is true. Sometimes the driver will change the measurement results by deliberate acceleration and deceleration, which will cause the vehicle weight measured by the truck scale to be different from the actual vehicle weight. There are large errors, which bring great inconvenience to road management
