Abstract
A kind of warehouse logistics navigation vehicle map tag, it is characterized in that: it includes RFID label tag layer (1), RFID label tag layer (1) upper surface is fitted with specular reflective layer (2), and RFID label tag layer (1) lower surface is fitted with glue layer (3).There is the function of RFID function and spectral reflectance simultaneously.When running into path deviation when navigation vehicle runs in warehouse, it is possible to carry out oneself's adjustment in time, improve the navigation accuracy of navigation vehicle, reduce the supporting cost of navigation system simultaneously.
Description
Technical field
This utility model belongs to logistic industry equipment technical field, the most just relates to intelligent logistics equipment, especially relates to a kind of warehouse logistics navigation vehicle map tag, has the function of RFID function and spectral reflectance simultaneously.
Background technology
Along with economic fast development, logistic industry also obtains tremendous expansion, turnover for goods, typically require construction logistics warehouse, owing to car loading is increasing, storage workload is the most increasing, becomes increasingly complex, in the urgent need to being realized the automatic unloading of warehoused cargo by intellectualized reconstruction, automatically freight.Intelligent storage system refer in warehouse logistics transportation without or only need a small amount of human users to complete, most transport operation are completed by robot, so that robot plays the effect of logistics trasfer linking in products storage circulation system, and in Intelligent storage system, the transfer of goods is realized at present often through automatic navigation vehicle AGV, the airmanship being currently used for automatic navigation vehicle AGV is mainly navigated by devices such as magnetic, electromagnetism, laser, vision, inertia.But above-mentioned several navigation mode all has the defect of himself, magnetic and electromagnetic navigation exist circuit to be fixed, easily destroyed shortcoming, and laser navigation needs the scanning of laser instrument unobstructed and with high costs, and controller is complicated, and operand is big；Inertial navigation precision is big, needs other sensor feedback signals to correct it and runs deviation.Therefore, existing navigation mode the most all can not solve low cost well, control the technical barrier problem of dynamic route simple, extensive navigation.When especially using automatic navigation vehicle in modern large warehoused logistics center, existing airmanship and the needs that modern logistics cannot be met of vehicle.
Utility model content
The purpose of this utility model is that the navigation accuracy for existing warehouse logistics RFID and visual identity navigation vehicle is low, the technological deficiency of navigation error cannot be corrected voluntarily, a kind of warehouse logistics navigation vehicle map tag is provided, there is the function of RFID function and spectral reflectance simultaneously.When running into path deviation when navigation vehicle runs in warehouse, it is possible to carry out oneself's adjustment in time, improve the navigation accuracy of navigation vehicle, reduce the supporting cost chatting navigation system simultaneously.
Technical scheme
In order to realize above-mentioned technical purpose, a kind of warehouse logistics navigation vehicle map tag of design, it is characterised in that: it includes that RFID label tag layer, RFID label tag layer upper surface are fitted with specular reflective layer, and RFID label tag layer lower surface is fitted with glue layer.
Further, described specular reflective layer scribbles spectral reflectance material.
Beneficial effect
The warehouse logistics navigation vehicle map tag that this utility model provides, has the function of RFID function and spectral reflectance simultaneously.When running into path deviation when navigation vehicle runs in warehouse, it is possible to carry out oneself's adjustment in time, improve the navigation accuracy of navigation vehicle, reduce the supporting cost of navigation system simultaneously.
Accompanying drawing explanation
Accompanying drawing 1 is air navigation aid schematic diagram in this utility model.
Accompanying drawing 2 is this utility model structural representation.
Accompanying drawing 3 is network topology figure in this utility model.
Detailed description of the invention
Below in conjunction with the accompanying drawings and embodiment, this utility model is described in further details.
Embodiment
As shown in Figure 1, a kind of warehouse logistics RFID and the navigation control method of visual identity navigation vehicle, it includes following step:
The first step, first geographical labels is set in warehouse course, as shown in Figure 2, described geographical labels includes specular reflective layer, being attached to by specular reflective layer on RFID label tag layer, the visual identifying system of navigation vehicle is replaced with Spectral Recognition System, before and after navigation vehicle, the plot that has within sweep of the eye of Spectral Recognition System manages label, for correcting the running orbit of dolly, the axis of dolly is made to keep essentially coinciding with the line of two pieces of geographical labels.In the region of insufficient light, can be by the LED light filling on Spectral Recognition System (general employing spectrum photographic head) side, to adapt to dark surrounds.
Second step, then by the navigation system control of geographical labels information input navigation vehicle；
3rd step, starts navigation vehicle, and the Spectral Recognition System of navigation vehicle reads the Vehicle Controller of specular reflective layer information input navigation vehicle, and the geography information in underground RFID chip can be inputted controller by the RFID card reader of navigation vehicle simultaneously；
4th step, the vehicle-mounted master controller of navigation vehicle calculates the current location of car body, and by the wireless module of navigation vehicle, car body positional information is sent to ground-based server simultaneously according to the geography information in RFID chip；
5th step, it is judged that navigation vehicle position and the precision runout value of RFID chip position；
6th step, Vehicle Controller send vehicle location adjustment signal give drive plate, the latter drive motor to rotate, thus adjust the kinematic parameter of car body, it is achieved the correction of car body course.
Geographical labels uses gridding layout, as it is shown on figure 3, ground distributor is slit in operation area rectangular mesh, one geographical labels of every lattice center arrangement.Navigation vehicle operationally runs along the line between geographical labels.Vehicle-mounted RFID card reader is positioned at below navigation car body, and when parking stall is above label, card internal information is read by vehicle, can obtain the positional information that vehicle is current.When the information of reading with RFID chip distance less than 10cm.
The advantage of this label is to store geography information by RFID chip, and chip reliability is high, and encapsulation is simple, and the life-span is long, changes when tag damage and is very easy to.
The warehouse logistics RFID of this utility model offer and the navigation control method of visual identity navigation vehicle, utilize the combination of RFID label tag and color lump, when running into path deviation when navigation vehicle runs in warehouse, oneself's adjustment can be carried out in time, improve the navigation accuracy of navigation vehicle, reduce the supporting cost of navigation system simultaneously.
