Method for implementing guiding system and zigbee module of indoor and outdoor automatic carrying vehicle

Abstract

The invention is an indoor-outdoor two-use automatic carrying vehicle guiding system and the zigbee module implement method, belonging to a guiding system for automatic carrying vehicle, comprising vehicle front-end CCD camera, on-wheel wheel decoder, field fixed point position, on-vehicle zigbee module and on-vehicle CPU. The guiding system can recognize guiding marks from ground images to obtain position and course information of the carrying vehicle; merge the position and course information and the vehicle body displacement information to make dead reckoning; real-timely locate and track the guiding marks; eliminate the interference of engine dithering; build up wireless communication of total control center with each carrying vehicle by the zigbee module to coordinate mutual operation of all carrying vehicles and provide anti collision forecast; correct the produced error of the decoder with time accumulation by wireless locating function of the zigbee module. And the guiding system is applied to indoor-outdoor two-use environment and has high guided locating accuracy.

Description

1. Technical field [0001] The indoor and outdoor dual-purpose automatic transport vehicle guidance system and the implementation method of the zigbee module of the present invention belong to the guidance system of automatic transport vehicles. 2. Background technology [0002] The automatic transfer vehicle system (AGVS) is an effective means of logistics transportation in today's flexible manufacturing system (FMS) and automated storage system. The core equipment of the automatic transport vehicle system is the automatic transport vehicle (AGV). As a kind of unmanned industrial transport vehicle, AGV was applied in the 1950s. Generally, batteries are used as power, and the load capacity ranges from a few kilograms to hundreds of tons. The workplace can be an office, a workshop, or a port or a wharf. Modern AGVs are computer controlled, with microprocessors on board. Most AGVS are equipped with system centralized control and management computers, which are used to optimiz...

Problems solved by technology

[0004] These guidance systems are very expensive, and for those systems that require high guidance accuracy, the cost of components is even higher

Moreover, some guidance methods require a relatively large transformation of the environment in which the automatic pallet truck operates, which invisibly increases the cost of the system.

For some environments that require trucks to shuttle between indoors and outdoors, the traditional automatic truck guidance system clearly exposes certain deficiencies
