Abstract

The invention provides a movable forklift automatic tracking method and device, and relates to the technical field of forklifts. The movable forklift automatic tracking method includes the steps of measuring the distance of a movable forklift and a tracking subject through a wireless distance measuring sensor, wherein the wireless distance measuring sensor comprises a signal transmitting end and asignal receiving end; horizontally scanning obstacles in front of the movable forklift through a laser sensor to obtain a plurality of data points, wherein the laser sensor is arranged at a preset height on the movable forklift; clustering the data points on the basis of the distances between the data points to obtain a clustering result; and determining a target cluster representing the trackingsubject according to the centers of all clusters and the distance measured by the wireless distance measuring sensor. By means of the technical scheme, the analyzed data points of the laser sensor serve as tracking targets, the uniqueness characteristic of the wireless sensor and the high precision characteristic of data obtained by the laser sensor are integrated, and the tracking precision of the intelligent forklift can be improved.

Description

technical field [0001] The invention relates to the technical field of forklifts, in particular to a method and device for automatically following a mobile forklift. Background technique [0002] Forklift is an industrial handling vehicle, which refers to various wheeled handling vehicles for loading and unloading, stacking and short-distance transportation of palletized goods. Forklifts play a very important role in the logistics system of enterprises and are the main force in material handling equipment. Widely used in various sectors of the national economy such as stations, ports, airports, factories, warehouses, etc. [0003] At present, some forklifts have an automatic follow function in the intelligent control mode. For example, Chinese patent CN201510498083.6 discloses a follow-up transport vehicle and its operating method. Wherein, the follow-up truck includes a car body, the car body is the car body of a pallet truck, the bottom of the car body has a wheel struc...
