Problems solved by technology

This method has the problem that the verification workload is too large, the verification process cycle is long, and it is not suitable for large-scale verification.
A complete calibration process moves at least dozens or even hundreds of tons of weights, and it takes several hours for the cooperation of multiple people
In addition, many existing models with fixed centers of mass (such as liquid tankers, cement tankers, special caravans, etc.) cannot or are difficult to load weights or objects under multiple (not less than 2) conditions of different centers of gravity, resulting in the inability to achieve known weight conditions Calibration of the on-board weighing system under

Embodiment Construction

[0013] Two-axle, three-axle, fourth-axle, fifth-axle, six-axle and other vehicles can use each axle as an independent channel or a combination of axles and axles as an independent channel, and the calibration method is similar. Now taking the three-axle vehicle as an example, the present invention will be described in detail in conjunction with the accompanying drawings and embodiments.

[0014] Such as figure 1 , figure 2 As shown in Fig. 1, a triaxle vehicle equipped with an on-board weighing system is quickly calibrated using this method.

[0015] Method 1: Each axis is an independent channel, a total of 3 channels.

[0016] Step 1. Select a suitable site where shaft or shaft group weighing instruments (including portable weighing instruments, shaft load weighing instruments, shaft group weighing instruments, etc.) can be placed or installed, and relevant weighing instruments (such as figure 1 , figure 2 medium weighing equipment).

[0017] Step 2, drive the empty ve...

Abstract

The invention discloses a method of rapidly calibrating a vehicular weighing system. The method achieves calibration of the vehicular weighing system by respectively weighing the vehicular weighing system in unloaded and loaded states. By adopting shafts, shaft groups or shaft group combination weighing equipment, the method achieves rapid, accurate and high-precision calibration on vehicular apparatuses. Various problems existing in conventional vehicular apparatus calibration processes are overcome. The method which has the advantages of simple calibration process, high precision, high efficiency, rapidness, low cost, etc. can be widely applied to various vehicle models. The method is successfully used for calibrating the vehicular weighing system.

Description

technical field [0001] The invention relates to quick calibration of a vehicle weighing system. Background technique [0002] With the development of the logistics industry, the number of trucks has also increased. Overloading of vehicles often leads to road and bridge infrastructure safety, road traffic accidents, casualties, etc., causing serious losses to the country, life and property. In this regard, although the country has taken various measures (mainly including the use of dynamic axle loaders and vehicle weighing systems for over-limit detection, etc.), and invested a lot of manpower and material resources, certain results have been achieved. However, many problems have been exposed in practical applications, mainly including: poor weighing accuracy, low traffic efficiency, and large consumption of manpower and material resources. For this reason, people have proposed source control and truck ETC, but the current weighing The equipment is difficult to meet the requ...
