Mobile positioning system and method for three-dimensional garage

Abstract

The invention relates to the technical field of three-dimensional garages, in particular to a mobile positioning system and method for a three-dimensional garage. Among them, the mobile positioning system includes stacker, transmission system and positioning system. The positioning system is configured to establish the position coordinate system of the three-dimensional garage according to multiple parking spaces, and according to the current initial position of the stacker and the target position to be moved in the position The coordinate position in the coordinate system controls the transmission system to drive the stacker to move. The mobile positioning method includes: establishing the position coordinate system of the three-dimensional garage according to multiple parking spaces; obtaining the current initial position of the mobile stacker and the target position to be moved; according to the position coordinates of the initial position and the target position in the position coordinate system, control The stacker moves. The mobile positioning system and method of the three-dimensional garage of the present invention utilizes the parking space sensing device to carry out spatial coding on the parking space, thereby positioning the target position of the stacker, which can improve the reliability of the positioning control of the stacker and reduce the control cost.

Description

technical field [0001] The invention relates to the technical field of three-dimensional garages, in particular to a mobile positioning system and method for a three-dimensional garage. Background technique [0002] With the improvement of people's living standards, automobiles have become an important means of transportation for people, thus making people's lives more convenient and faster. However, with more and more vehicles, parking has become the biggest problem in public areas with a lot of traffic. In order to solve this problem, three-dimensional parking garages have been produced. [0003] At present, the movement of the stacker (carrier) of the three-dimensional garage is mainly driven by a motor-driven chain or a wire rope to drag the stacker to complete horizontal movement in the horizontal direction and vertical lifting in the vertical direction. The movement speed and start and stop of the stacker need to be controlled by changing the speed and start and stop ...

AI Technical Summary

Problems solved by technology

[0004] There are two traditional control methods, one is to use the encoder to detect the relative displacement of the stacker, so as to control the speed and start and stop of the electrode through the relative displacement, but the cost of the encoder is relatively high, and due to the working conditions, installation The accuracy and maintenance will affect the reliability and stability of the encoder; the other is to install a detection switch or a proximity switch in each parking space, and encode the absolute value of the parking space, and control the motor according to the input coding command However, if a detection switch or proximity switch is to be installed in each parking space, the cost of the sensor will be high, the circuit will be complicated, and the number of fault points will increase.

[0005] In addition, safety protection measures (including dislocation, limit, loose chain, broken chain protection and sensor failure alarm, etc.) are another important indicator of the three-dimensional garage. However, the existing safety protection measures are either too costly or difficult to install and maintain. , or the security protection measures are not perfect, the performance is not good, and neither can meet the security protection requirements

[0006] Therefore, in view of the problems of low reliability and high cost of stacker positioning control in stereoscopic garages in the prior art, it is necessary to provide a low-cost, high-reliability mobile positioning system and method for stereoscopic garages
