Embodiment Construction

[0017] The technical solution of this patent will be further described in detail below in conjunction with specific embodiments.

[0018] see figure 1 , a simple vehicle weighing device, including a sensor 3 and a spring 4; the sensor 3 is fixed at both ends of the axle 1 of the vehicle, the lower end of the spring 4 is connected to the sensor 3, the upper end is fixed at the bottom of the compartment 5, and the spring 4 is installed After completion, it is in a stretched state, and the sensor 3 is subjected to a pre-tensioning force.

[0019] The working principle of the present invention is: described simple and easy vehicle weighing device, because the load of vehicle is proportional to the descending height of compartment 5, the greater the descending height of compartment 5, the smaller the elongation length of spring 4, known spring 4 The elongation is proportional to the tension of the spring 4, which is the tension measured by the sensor 3, so the vehicle load is inve...

Abstract

The invention discloses a simple vehicle weighing device and method. The simple vehicle weighing device comprises sensors and springs. The sensors are fixed to the two ends of each vehicle shaft of a vehicle. The lower ends of the springs are connected with the corresponding sensors. The upper ends of the springs are fixed to the bottom of a compartment. The vehicle weighing device weighing method includes the steps that 1, the two ends of each vehicle shaft of the vehicle are provided with the sensors respectively, the lower ends of the springs are fixed to the corresponding sensors, and the upper ends of the springs are fixed to the bottom of the compartment; 2, when the vehicle is empties, zero calibration operation is conducted on the sensors; 3, goods are loaded on the vehicle till the vehicle is fully loaded with the goods, and weighing calibration is conducted on the sensors; 4, a calibration curve is generated according to the output signals under the empty state and the fully-loaded state of the vehicle and the load capacity under the empty state and the fully-loaded state of the vehicle; 5, when the vehicle is loaded with the goods unknown in load, the load value of the vehicle is obtained according to the output signals of the sensors and the calibration curve. The simple vehicle weighing device is simple in structure and low in cost, and the method is relatively easy and convenient to implement.

Description

technical field [0001] The invention relates to the field of vehicle weighing, in particular to a simple vehicle weighing device and a weighing method. Background technique [0002] Overloading of vehicles, especially trucks, is a major cause of road damage. At the same time, it will also cause damage to the vehicle and cause traffic accidents. In the existing over-loading methods, it is common to use a weighbridge or an axle load scale to verify the weight of the cargo after loading, and if it is found to be overloaded, a fine will be imposed. But this method can only treat the symptoms, not the root cause, and fails to treat it from the source. [0003] As a result, the weighing method of on-board weighing came into being, that is, sensors are installed on the car to realize weighing while loading, and stop loading when it is found to be overloaded. In the current vehicle weighing method, it is divided into direct force measurement weighing and indirect force measur...
