Description
Technical field
The invention belongs to Internet of Things wireless control technology field, be specifically related to based on wireless network for AGV
The device of system information display function.
Background technology
Along with factory automation, the progressively development of computer integrated manufacturing system technology and flexible manufacturing system
System, the extensive application of automatic stereowarehouse, AGV (Automated Guided Vehicle) leads the most automatically
Draw car as contact and regulation discrete type logistics system so that the necessary automated handling of its operation serialization
Handling means, its range of application and technical merit have obtained swift and violent development.AGV is with microcontroller for control
Core processed, technology of Internet of things be support, accumulator is power, drive equipped with nobody of noncontact guiding device
Sail homing guidance carrying cart, the basic function of its automatic job be guide travel, recognize location stop standard and transfer carry
Lotus.Process effective means and the key equipment of flexible manufacturing system of automatization as logistics in the present age, AGV is
Increasingly it is widely applied through having obtained.
At present the guide mode of AGV can be divided into two big classes: car extenal fixation route guidance mode and free path
Guide mode.Car extenal fixation route guidance mode refers to arrange the information media guided on the path travelled
Thing, AGV is guided by the information detecting it, such as electromagnetism guiding, optical navigation, tape guidance
Deng；Free path guide mode is to store the scale coordinate on system layout on AGV, by identifying car
Body present orientation, autonomously decides on driving path, and this kind of guide mode is also referred to as software programming road on car
Footpath mode.Wherein car extenal fixation route guidance mode is usual way.
AGV system application mainly there is equipment to have four kinds, is Vehicle Controller, website calling set, collection respectively
Middle coordinator and information display.The control instruction of AGV is usually and is proposed by website calling set, through concentrating association
Tune device sends, and the state of AGV sends concentration coordinator back to also by communication system, and communication system has two kinds: even
Continuous mode and dispersing mode.Continuous communiction system allow AGV at any time with relative ground controller
Any position uses radio frequency method or uses the communication cable in guide path to receive and send messages.As used nothing
Line electricity, the communication means of iraser.Distributed system simply predetermined place such as AGV calling website,
Vehicle Controller, information display etc., communicate with concentrating to provide between coordinator at specific AGV equipment.
In general, this communication is that the method by radio network technique realizes, Decentralized Communication mode
Advantage be that price is relatively inexpensive, reliable communications is stable.
In AGV system, the major function of information display is mounted in the specific position of factory and claims station to show
Vehicle and website call information, when needing material to be transported on station or to have ready-made goods to need to transport,
Operator can utilize Zigbee wireless network by the demand of button by the button by website calling set
It is transferred to concentrate coordinator, concentrates coordinator according to the situation of car in garage at that time, send a kind of station with charge free
The car type that website calling set requires, path optimizing, it is stipulated that purpose website and the behavior at each road junction along road,
These information shows at information display by Zigbee wireless network, real-time update vehicle and calling website
Information, and can have the selection display type of Current vehicle, license number and target call station by the condition of station
Point numbering, contribute to stock and the unloading of station, information display can act on again wireless signal relaying,
Data forwarding capability.
