Embodiment Construction

[0036] The specific stair climbing implementation of the intelligent stair climbing vehicle can be realized through the steps of going up and down:

[0037] a. Steps up the steps:

[0038] 1) The car moves forward, and the ranging sensor measures whether there are steps between the car and the front;

[0039] 2) When the forward sensor detects that there is a step in front, the measured data is transmitted to the control computer, and the computer determines the distance and height of the step through analysis and calculation, and controls the vehicle speed at the same time. And judge whether the distance between the wheel and the step is too small; if it is too small, the control stops advancing to ensure that the car does not collide with the front step; image 3 )

[0040] 3) In the process of deceleration and stopping, the computer controls the push-pull rods corresponding to the other wheels that are not close to the steps to be pushed downward synchronously, so that th...

Abstract

The invention discloses a technology and method of an intelligent stair climbing vehicle. The technologies such as sensors and push-pull rods are used, and a computer control method is used for realizing a vehicle body going up and down stairs. In addition to a controlled object, that is, the vehicle body, the intelligent stair climbing vehicle is mainly composed of a sensing part, a control partand an executing part. The sensing part is composed of a ranging sensor, a pressure sensor and the like. The control part is composed of a data collector, an embedded type computer, software and the like. The executing part is composed of an advance and retreat system and a lifting system. The advance and retreat system consists of eight power wheels, a controller and the like. The lifting systemconsists of four or eight electric push-pull rods, a controller and the like. (Figure 1) The intelligent stair climbing vehicle senses the external environment and own state in real time through the sensors and transmits the information to the computer. Based on the information, the computer controls the up and down movement of the electric push-pull rods and the forward movement of the electric wheels by comparing, analyzing, discriminating and calculating, and therefore being up and down stairs autonomously is realized.

Description

technical field [0001] The vehicle includes a combination of sensor measurement, computer system, power wheel system, power push-pull rod up and down movement system and software algorithm, and it is a complete system involving equipment and control methods. In particular, it involves machinery, electrical machinery, electronics, optoelectronics, computers, automatic control and software, and belongs to the fields of robotics, intelligent control, and automatic driving. Background technique [0002] Steps and stairs can be said to be one of the great inventions of mankind. With it, human beings can free their hands in the process of climbing mountains and other upwards, just like walking on flat ground. It has played an important role in human development. It is the inevitable product of human progress. But no matter for the elderly and the disabled with poor legs and feet, or for carrying heavier objects, it is still an insurmountable obstacle. Especially in buildings w...
