According to above preferred embodiment, the disclosed gap bridge fitting identifying system based on RFID of present patent application, ginseng
See Fig. 1 of attached drawing, process control is described below: on line at walking robot normally travel to 3 meters of gap bridge fitting A, read-write
Device reads the passive label 1 at the end fitting A, then feeds back to mainboard, and mainboard controls movable motor and slows down, and low speed moves forward.?
During the end A, reader continuously sends out signal, updates robot and fitting approximate distance.When robot passes through gold of passing a bridge
Tool starts to pass a bridge, and after travelling a distance, reader reads the information of the end fitting B passive label 2, and real-time update is big with it
Cause distance.By the way that behind the end fitting B, robot completes to pass a bridge, move forward always according to low speed to after at 3 meters away from the end fitting B,
Passive label 2 exceeds the read range of reader at this time, and the two is shaken hands disconnection.Reader does not receive 2 signal of label, feeds back to master
Plate, mainboard control movable motor and accelerate, travel according to normal speed.
Specifically, RFID reader is installed in robot on line, continuously sends out signal, and passive label is mounted on gap bridge
On fitting.When robot will pass a bridge close to fitting, reader can read the information of label in certain distance, be prompted with this
Certain distance carries out gap bridge movement in front of robot.After the completion of gap bridge, robot travels longer than certain distance and does not receive nothing
Source label information is completed with this to prompt to pass a bridge.
The reader of RFID and the distance substantially judgment mode of passive label are big by adjusting the transmission power of reader
It is small to realize.Such as, it is first determined required reader is minimum when both reader and passive label are at a distance of 1 meter, 2 meters and 3 meters
Transmission power F1, F2 and F3, then reader successively sends 3 power, when the two is at 3 meters, the only transmission power of F3
It can be made to shake hands, at 2 meters, F2 and F3 can make it shake hands, and at 1 meter, F1, F2 and F3 can make it shake hands.Emitted by judgement
The minimum power that power is shaken hands can substantially judge to connect this and distance.
According to above preferred embodiment, the disclosed gap bridge fitting identifying system based on RFID of present patent application is
Walking robot provides a kind of mechanism for being easily achieved identification object on line, realizes that robot passes a bridge and takes action, its advantages are explained
State as follows: walking robot is before gap bridge on line, as long as reader can read label information, success of shaking hands just can know that front
There is corresponding barrier, completes to pass a bridge so that robot executes corresponding operating.Disturbance in judgement object size shape is not needed, is not needed
Accurately gap bridge movement can be completed in distance for the real time measure robot and tower head.
For a person skilled in the art, technical solution documented by foregoing embodiments can still be repaired
Change or equivalent replacement of some of the technical features, it is all within the spirits and principles of the present invention, made any to repair
Change, equivalent replacement, improvement etc., should be included in protection scope of the present invention.
