Car positioning control method and system based on discrete coordinate system

Abstract

The invention discloses a method for controlling trolley traveling positioning based on a discrete coordinate system. A route of a trolley is internally provided with a plurality of detection switches which are arranged at intervals. The method comprises the following steps that the discrete coordinate system related to the route of the trolley is established, wherein each detection switch corresponds to a coordinate value in the discrete coordinate system, the plurality of detection switches are arrayed in sequence from left to right, and coordinate values are changed in an arithmetic progressive increasing manner; when any one detection switch is triggered in the trolley traveling process, the coordinate value of the triggered detection switch is recorded as X1; the coordinate value of a trolley stopping destination in the discrete coordinate system is recorded as X2; the X1 is compared with the X2; a traveling direction and a traveling speed of the trolley are controlled according to a difference value X3 between the X1 and the X2. The method provided by the embodiment of the invention has the advantages of strong universality, and accuracy and reliability in positioning control. The invention further provides a system for controlling the trolley traveling positioning based on the discrete coordinate system.

Description

technical field [0001] The invention relates to the technical field of transmission control, in particular to a method and system for controlling the positioning and positioning of a trolley based on a discrete coordinate system. Background technique [0002] The trolley walking control has a wide range of applications in the transmission field, and the positioning of the trolley on the travel route is the core of the control. The car often needs to stop and go on a travel route. For example, there are multiple stop points on a travel route, that is, for the tasks performed by the car, it is often necessary to decelerate and stop at multiple positions. [0003] At present, the means of positioning control of the trolley usually adopts the arrangement of proximity switches for triggering the stop signal at multiple stop points on the travel route of the trolley, and arranges a plurality of proximity switches for triggering the deceleration signal at multiple points where dece...

As a result, the above control methods lack flexibility and poor applicability, and it may be necessary to rearrange the position of the proximity switch or redefine the meaning of the proximity switch for different tasks, resulting in a heavy workload and error-prone
