Freight vehicle weighbridge monitoring method capable of preventing weighing cheating

Abstract

The invention provides a freight vehicle weighbridge monitoring method for preventing weighing cheating. The monitoring method is based on an acquisition unit in a metering system. A camera and a laser scanning sensor which are erected above a weighbridge are used as acquisition components; and the camera faces a direction that a vehicle drives into the weighbridge, a scanning surface of the laserscanning sensor is vertically downward and is parallel to a driving direction of the vehicle, and in an unattended state, the camera completes information comparison, identification and alarm of features of the detected vehicle to remove the unmatched vehicle. Whether the detected vehicle is driven into the weighbridge and is stabilized in a normal weighing area is judged according to scanning information of the laser scanning sensor, and an alarm is given to remove abnormal cheating weighing behaviors. According to the technical scheme, vehicle operation is not affected, rolling loss, contact and barrier collection setting are avoided, maintenance is easy, and a service life is long.

Description

technical field [0001] This patent application relates to a method for monitoring the weighing position of freight vehicle scales, in particular to a monitoring method for weighing scales that uses non-contact physical detection means to monitor and eliminate abnormal weighing. Background technique [0002] The weight of the goods carried by the vehicle is mainly measured by the weighbridge as the measuring equipment. The vehicle passes through the weighbridge, and the weighing value obtained each time is calculated by the increase or decrease of the vehicle storage volume and the storage volume to complete the accounting records of the total volume of goods storage, storage volume, and total inventory. plays a very important role in billing. However, the existing weighing measurement method requires manual participation in the operation, which is not only inefficient and error-prone, but also for various reasons, cheating is prone to occur in the weighing operation of weig...

AI Technical Summary

Problems solved by technology

However, the existing weighing measurement method requires manual participation in the operation, which is not only inefficient and error-prone, but also for various reasons, cheating is prone to occur in the weighing operation of weighing goods into the warehouse and weighing products out of the warehouse, resulting in serious errors in measurement values. Accurate, causing a loss that cannot be underestimated to the enterprise

[0003]Because the current weighbridge measurement system and measurement method do not fully consider how to prevent cheating and eliminate the occurrence of cheating while obtaining accurate weighing information, in order to reduce business loss
