Car weighing method

Abstract

The invention relates to a vehicular weighing method which can be used for conveniently measuring the weight of on-board goods in real time. The vehicular weighing method comprises the following steps: additionally installing a plurality of strain sensors on an axle; additionally installing test bodies in different positions of a truck bed, and reading the reading of each sensor during each additional installation; constructing a statically indeterminate equation according to a test body weight array, a sensor reading array and a distribution coefficient array of each sensor, and solving a least square solution of the statically indeterminate equation to obtain an optimal distribution coefficient of each sensor; additionally installing test bodies in any position of a compartment in proper order, reading the practical weight of the test bodies during each additional installatio, reading the reading of each sensor during each additional installation, and determining measuring errors during each additional installation; performing polynomial fitting to determine a relationship between a measuring error value and the measured weight, and obtaining the practical weight of the on-board goods according to the sum of the actual measured weight and measuring errors of the on-board goods.

Description

technical field [0001] The invention relates to a vehicle-mounted weighing method, which belongs to the field of vehicle electromechanical integration. Background technique [0002] At present, the quality of the goods loaded on the vehicle can only be obtained by weighing on the scale, and the vehicle itself cannot judge. In many cases, due to the inability to obtain the actual quality of goods conveniently, in the case of the country's "governance of overloading", vehicles are often unable to run normally due to overloading. At the same time, mastering the changes in the quality of goods during transportation is also very beneficial to the safe transportation of goods and the management of the fleet. Therefore, it is urgent to develop a vehicle weighing system that can obtain the quality of goods in a convenient and real-time manner and can track changes in the quality of goods throughout the process. The situation has met the market demand. Contents of the invention ...
