Portable running-vehicle weighing instrument

Abstract

The present invention relates to the weight machinery, and may be used in real-time measurement and evaluation of vehicle load without affecting its normal running. Pressure oil rubber pipe is set in road, hand pump and pressure sensor are mounted at the end of the rubber pipe and pressure signal is transmitted from the pressure sensor to the signal processing instrument. One or several rubber pipe may be arranged in the road in different angle or arrangement mode as required. Video camera for recording vehicle plate number automatically may be added. The present invention may be used to measure load, speed and wheel base of vehicle in different running speed.

Description

Technical field [0001] The invention relates to the field of weighing (mass) machinery, in particular to a portable vehicle weighing instrument during driving, which can realize real-time measurement and evaluation of the vehicle load without affecting the normal running of the vehicle on the road. Background technique [0002] At present, the domestic automobile load measurement completely adopts the method of weighing. Generally, it is pre-determined whether the car is overloaded based on visual inspection. For suspicious cars, let them drive into the car weighing system on the side of the road, and statically measure the wheel load of the car to judge whether the car is overloaded. The weighing system generally adopts the method of physical weighing, and a weighing table, base and sensors are arranged. This test system has the following disadvantages: (1) the vehicle must be intercepted to drive it onto the weighing platform, which not only has low test efficiency, but a...

AI Technical Summary

Problems solved by technology

This test system has the following disadvantages: (1) Vehicles must be intercepted and driven onto the weighing platform, which not only has low test efficiency, but also affects the driving of other vehicles and the smooth flow of the road, and may induce traffic accidents

(2) Since it is impossible to arrange weighing devices across the entire width of the road, it will cause overloaded vehicles to escape inspection

(3) The structure and mass of the detection system are huge, inconvenient to carry, inconvenient to arrange, and inconvenient to inspect

At present, foreign weighing systems are mostly platform-based, which are only suitable for measuring and testing at fixed testing stations.

At present, the most advanced detection method abroad is the LINEAS quartz force sensor weighing system in motion (www.kistler.com) of Switzerland Kistler Co., Ltd., which is only suitable for installation and detection in a fixed lane; and it uses quartz Crystal sensor, not only expensive, the length of the sensing element is limited, but also unable to measure static and quasi-static weighing
