Portable ground slope testing device and testing method

Abstract

The invention, which belongs to the technical field of ground slope detecting equipment during a vehicle driving process, discloses a portable ground slope testing device and testing method. The slope of the ground is detected by using a difference method, an initial slope value is measured by a slope data detecting module, a ground slope value is obtained based on a difference between a slope measured by a double-axis tilt angle sensor in real time and the initial slope value, and a ground slope value at each time during the field vehicle driving process is recorded; a GPS terminal is used for obtaining and recording position information at each time at the field; the path of the driving process of the field vehicle is divided into a plurality of sections by starting with time t being equal to 0; and then measured real-time slope information is divided into several segments and then an average value is taken, the positions of all sections correspond to average value information of the slopes of the sections one by one, so that slopes of all sections at the field vehicle driving path are obtained. The ortable ground slope testing device and testing method can be applied to the large and small-sized motor vehicles, on-site motor vehicles, etc. widely. Compared with the traditional slope detection device, the in-field motor portable detection device enables the detection result to be true and accurate and thus has the great reference significance.

Description

technical field [0001] The invention belongs to the technical field of ground slope detection equipment during vehicle driving, and in particular relates to a portable ground slope test device and a test method. Background technique [0002] At present, the closest existing technology: a part of the technology uses a triaxial acceleration sensor to measure the inclination of the ground; a part of the technology uses the GPS system to obtain the height of the ramp and the length of the bottom of the ramp to obtain the road gradient; there are also road gradient tests based on gradient resistance and The traditional human manually detects the slope level. [0003] The pace of development of my country's industry is also accelerating, and the number of motor vehicles used by various types of enterprises is increasing day by day, and the application range of motor vehicles is also constantly expanding. The important position of special motor vehicle transportation in the field ...
