Description
Technical field
The cascaded structure of RFID tag belongs to radio frequency identification (RFID) technology, and is a robot the relevant technologies.
Background technique
Robot grass trimmer belongs to self-moving robot, and scope of activities or work boundary need to be manually set.Machine at present
There are two types of boundary setting methods for device people's grass trimmer commodity, first is that feeling line as boundary, second is that GPS in meadow laying signal wire
It defines.Wherein GPS 3 meters of stated accuracy in civilian situation are not suitable for household grass trimmer robot, so the grass trimmer machine of mainstream
Device people's product is using ground sense line boundary.But the method that line is felt in careless over ground installation has very big limitation: 1, constructing more multiple
It is miscellaneous, there is certain technical threshold.Grass trimmer robot definitely feels the current direction of line by Ampere's law and determines boundary side
To electric wire connection cannot be reversed.2, line is felt once being arranged, it has not been convenient to be changed and be migrated.Since meadow water content is big, resistance to suction is electric
Magnetic wave, embedment ground sense line can make electromagnetic induction faint to failure, so ground sense line is generally laid in earth's surface.And the fixation of ground sense line is stayed
It is easy to be involved in grass trimmer in earth's surface and be cut off, and have security risk, be easy to trip pedestrian.Although 3, robot grass trimmer can be with
The direction on boundary is determined by Ampere's law, but not can determine that oneself in borderline position, so returning to starting point often needs
Long-range is wanted to traverse boundary, secondly under the auxiliary of no other technologies means, its motion path randomness is excessive, makees each time
Industry is all surplus not covered block.
If only for robot, there are also other, much scientific and technological methods may be used to determine boundary, but in domestic appliance
Under the application scenarios of people's grass trimmer, not yet proved to have by market applicable.Such as the method for the method and infrared ray of laser, precision
Height, but it is complicated to construct, it is helpless to live tortuous boundary, and may cause the damage to human eye especially children's eyes.
At present it is not yet found that patent or research are related to RFID technique come the work boundary of marking machine people's grass trimmer,
It finds no patent or research is related to coming the work boundary of marking machine people using RFID technique.But, Chinese patent application
201410420276.5 (2014, Xu little Min) disclose a kind of method using RFID technique to robot external guidance, can also
To determine the boundary of robot, but it needs to configure perfect external antenna array, is not suitable for outdoor domestic robot and mows
The application scenarios of machine.
Summary of the invention
Cascaded structure (being hereafter also known as " the present invention ") design of RFID tag uses radio frequency identification on class bead structure
Label flag node utilizes the identification code of the read-write memory storage adjacent node RFID tag of RFID tag
(TID), data link table is established, the RFID tag set of logic association is formed, for node on mapping class bead structure
Physical location correlation.
Node object is connected by connecting medium with adjacent node object, is linked to be string one by one.Such as Fig. 1, A node
(101) B node (102) are connected, B node (102) connects C node (103), reconnects D node (104) down to more nodes.A,
B, C, D intra-node have perforation hole (121), for connecting passing through for medium.Such as Fig. 3, E node (105) and F node
(106) it is connected, there are ring (123) on their body surface, be used for and connect medium and link.The present invention to the unlimited shape of node object,
Depending on concrete application.Such as the work boundary as the present invention as robot grass trimmer, then there is landscape to node object
It is required that the requirement with waterproof, node object can be designed to the shape of various stones, and inside sets cavity and places RFID tag.
Connection medium can be flexible rope (125), including cable, clue, wire, chain, a chain of this kind of objects
Part;It is also possible to rigid connecting rod (127), including object as club, pole, bar.Connection method can be perforation, can also be with
It is latch closure.When the method using perforation, connection medium is placed stop at hole hole by through hole (121)
(126).Stop keeps the distance between node and node for preventing node object from sliding on connection medium.Stop
It can be a knot, be also possible to other additional objects and be stuck on connection medium.When the method using latch closure, medium is connected
It ties up on the ring (123) of node object or is buckled on the ring (123) of node object by included ring (128) hinge.
Each node object lays RFID tag, and RFID tag identifies node object, these labels
Identification code (TID) is just simultaneously at the mark of node.According to the requirement of EPCglobal C1G2 or ISO 18000-6C, radio frequency
The identification code of identification label is stored in the TID field of radio frequency identification label chip.The RFID tag of separate sources is in TID field
Configuration may be different, and some only has a tag identifier code (TID), and there are one the unique tag identification codes extended for some
(Unique TID or UTID).In actual use, uniquely distinguishing a piece of RFID tag, there are three types of situations: by TID, passing through
UTID passes through TID+UTID.It is convenient for statement, as referred to three kinds of situations above with TID without being specifically described in this document.
RFID tag can be adhered to node body surface.Such as the RFID tag on A, B, C, F node point
Not Wei label a (410), label b (420), label c (430), label f (460), be pasted onto the surface of respective nodes object.Section
Cavity (122) can also be carried in point object body, for accommodating RFID tag.For example D, E node divide in this way
It Rong Na not RFID tag d (440), RFID tag e (450).RFID tag is accommodated in the side of internal cavity
Method is suitble to need the occasion of waterproof.
RFID tag all using the label for having read-write memory block, i.e., the chip interior of these labels in addition to
TID field, there are also read and write memory block to can be written into the TID of other at least a piece of RFID tags.Such as Fig. 2, label b on B node
(420) TID that chip has TID field (421) to have ownb, there is read-write memory block (422) to have radio frequency identification on right node
The TID of labelc, sensing label c (430) indicates that the right neighbours of B node are C node (103).TID field in (410) label a
(411) there is TIDa, have TID in read-write memory block (412)b, indicate that the right neighbours of A node are B nodes, in turn B node
Left side neighbours be A node.Here left and right saying is the artificially defined of statement for convenience, for the view of opposite Fig. 1.
TID field (431) in (430) label c has TIDc, have right node label d's in read-write memory block (432)
TIDd.TID field (441) in (440) label d has TIDd, have the TID of right node label y in read-write memory block (442)y。
The rest may be inferred for other node situations.
If TIDy=0, indicate that label y is not present, D node is exactly the endpoint of cascaded structure.If TIDy=TIDa, table
The right adjacent node for showing D node is exactly A node, and cascaded structure is a ring.Similarly, if there is no a non-A node mark
Label store TIDa, then A node is the endpoint of cascaded structure.
It label a, b, c, d and is more associated with similar stored data and is combined and just constitute a single-track link table
Data structure maps the node physical location phase of a cascaded structure being made of A, B, C, D node and more nodes
Mutual relation.Here the concept of chained list has borrowed the definition of chained list (linked list) in computer science data structure theory.Appoint
What radio frequency identification reads equipment, can be started by reading any one node on cascaded structure, understand the letter of adjacent node
Breath.When using cascaded structure of the invention as boundary, robot grass trimmer can since arbitrary node, order traversal node and
Copying whole data structure in memory.Oneself can be expressly understood that in borderline position when it returns to certain node.Robot
Can also work operational process in random ergodic, pass through the continuous entire data structure of bonding data segment step-by-step replication.
The making material of node object of the present invention selects PVC material.
The beneficial effects of the present invention are:
(1), for relatively single label, it is relevant that RFID tag with technical solution of the present invention assembles logic
After cascaded structure, a vector boundary can be used as, to determine the work boundary of robot, or undertake blind person's equipment guiding etc.
Responsibility;Radio frequency identification reads equipment by traversing cascaded structure of the invention, can grasp the overall condition on boundary rapidly, work as reading
Equipment is taken to return to a certain node, it will be appreciated that the trend on boundary and from borderline accurate location;
(2), when the work boundary as robot, setting and change are simple, can be according to any requirement of working site
Put boundary;In the application scenarios of domestic robot grass trimmer, the method for line, the technical threshold of initial setting up are felt compared to laying
It is zero;
(3), cascaded structure of the invention can be stored, can be carried, and a work boundary of robot can be removed rapidly
Pin, or move to another place.The convenience of storage eliminates security risk, and the delay for feeling line without ground eliminates the need for
The accident probability that people is tripped.
