Embodiment Construction

[0024] Depend on figure 1 It can be seen that the indoor and outdoor dual-purpose automatic transport vehicle guidance system of the present invention includes: a CCD camera, a zigbee module, a wheel decoder and a central processing unit, wherein:

[0025] Zigbee module: It is mainly placed on the truck and in several fixed positions on the ground. The Zigbee module has low power and is about the size of a credit card.

[0026] CCD camera: placed directly in front of the truck, with a 4M square road in front of the field of vision. The resolution of CCD is about 1 million.

[0027] Wheel decoder: placed on the front wheel of the truck. The price depends on the accuracy required by the system and is very low.

[0028] Central processing unit: placed on the truck, it is currently implemented with an industrial computer. After commercialization, DSP can be used to make the central processing unit of the control board to reduce costs.

[0029] The system installs a CCD camera...

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...
