Cartesian coordinate system based forklift site test boundary detection device based and method thereof

Abstract

The invention discloses a Cartesian coordinate system based forklift site test boundary detection device and a method thereof. The method comprises: a step 1, taking a Beidou ground station as an origin, and establishing a Cartesian coordinate system with an arbitrary straight edge passing through the origin and parallel to a runway outer boundary as an X-axis; a step 2, converting the runway intothe Cartesian coordinate system, and dividing the runway in the Cartesian coordinate system into five areas; a step 3, converting a forklift into the Cartesian coordinate system, recording an actualcoordinate position of the forklift in a test in real time through a mobile station mounted on the forklift, performing calculation with the five areas of the runway to determine if the forklift presses or goes out of a line; and a step 4, capturing and recording an image if it is detected that the forklift presses or goes out of the line. The device and method can accurately determine line pressing behaviors of the forklift and line outgoing behaviors of the forklift, performs video capturing and evidence collection, and can provide a basis for the test evaluation.

Description

technical field [0001] The invention belongs to the technical field of forklift examination, and in particular relates to a detection device and method for the boundary of forklift field examination based on a Cartesian coordinate system. Background technique [0002] Forklifts are an important means of transportation in ports, docks, warehouses and other places, and their safe operation is very important. Government functional departments are paying more and more attention to the safe operation of forklifts, and the examinations for forklifts are becoming increasingly strict. On the other hand, the pursuit of objectivity and fairness in test scoring, so that there is a basis for deduction of points, and evidence for reverse investigation. The detection and judgment of the forklift position during the forklift site test is one of the difficulties. Most of them rely on manual judgment, which inevitably affects the objectivity and fairness of the test. How to use information ...

AI Technical Summary

Problems solved by technology

However, this device cannot accurately judge the forklift’s line pressure and exit, especially in the arc area of ​​the examination room, it is difficult to accurately detect the pressure line and exit of tires and car bodies through photosensitive or infrared sensors. At the same time, the solution requires the number of sensors to be arranged Many, high complexity of system hardware equipment
