Fig. 2 is the period composition schematic diagram of the infrared signal of one embodiment of the invention:
Fig. 3 is the method flow diagram that present example adjusts that infrared anti-collision emits the launch time of scanning signal.
[specific embodiment]
Explanation is further explained now in conjunction with drawings and examples to be illustrated that the present invention in further detail.
Present example refers to Fig. 2, and Indoor Robot is playbacked using the infrared positioning signal of charging pile, wherein is filled
The infrared positioning signal of electric stake is sent with the infrared anti-collision signal sending cycle of Indoor Robot alternately, and single
Infrared anti-collision signal and infrared positioning signal are sent at times in period.
As shown in Fig. 2, (present example is 3 to the infrared positioning signal of charging pile periodicity sending multichannel process coding
Road), Indoor Robot distinguishes positioning to being decoded after receiving infrared positioning signal, determines the direction of charging pile.When
The infrared positioning signal control of charging pile is completed to send within the previous period (Time 1) by preceding embodiment, and periodically raw
At cycle time sets T.The signal of the anticollision of infrared anti-collision module is also to be emitted according to same periodicity simultaneously, one
Equally control is completed within the latter period (Time2) in a period.Need to meet condition T > (Time l+Time 2) i.e. at this
The signal for needing to be able to satisfy both sides in period is sequentially completed.Interaction between charging pile and Indoor Robot is as shown in Figure 3.Because
The anticollision minimum detection distance of Indoor Robot is D, and considers most extreme case, and robot braking needs certain braking distance
D, wherein the movement speed of Indoor Robot is V, therefore the selection of cycle T needs to meet robot present speed V*T+d < D.Institute It should be for less than or equal to (D-d)/V and greater than (Time l+Time 2) with T value range.Cycle T composition can refer to Fig. 2.Wherein
Contraposition lamp A, contraposition lamp B and the range light of charging pile in turn send infrared positioning signal at times, infrared positioning signal
Previous period Time 1 completion for concentrating on a cycle T is sent, and in latter period Time 2 then for Indoor Robot
Infrared scan hair penetrates infrared anti-collision signal, is scanned, to realize anticollision purpose.It wherein aligns lamp A, contraposition lamp B and leads
Infrared positioning signal transmitted by lamp of navigating is the encoded signal of 38KHz, i.e., different coding letters is superimposed with using the carrier wave of 38KHz
Resulting encoded signal is ceased, encoded information is generally 8 or 16 addresses by coding, for distinguishing infrared positioning signal
Sender, robot is parsed to obtain the infrared positioning signal to be which is red after receiving infrared positioning signal indoors
Outer positioning signal, is calculated the infrared positioning signal sending time of remaining corresponding two-way, and then extrapolates infrared anti-collision
The sending time of signal.
During alternately sending, because charging pile is generally between Indoor Robot, none is temporal together
Step, so it is difficult to ensure that even, but both sides time counting is that have difference as robot with charging pile start time is
It is other, so the time, which has been grown, also has temporal cumulative errors.It thus needs robot that can adjust infrared anti-collision transmitting to sweep
Retouch the launch time of signal.It therefore can be temporal " right to charging pile and Indoor Robot progress after several periods
It is quasi- ", one embodiment of the invention uses the method such as Fig. 3 to be adjusted every five periods, and method of adjustment includes: to receive
Infrared anti-collision signal is judged whether it is when infrared signal: if it is, handling and continuing in the completed infrared into anticollision
The reception and judgement of signal: otherwise, the sending time for obtaining remaining infrared positioning signal is calculated, and infrared according to calculated result
The sending time of anticollision signal is adjusted to infrared positioning signals transmissions all in current period.
Sometimes since the time of adjustment is smaller, or the factors such as infrared positioning signal delay when next period starts,
Cause infrared anti-collision signal adjusted still can conflict with infrared positioning signal, at this moment just needs to carry out verification processing.Therefore
In the case that present example had carried out the adjustment of infrared anti-collision signal sending time within a upper period, detected in current period
It further include that the adjusted sending time of verifying is after infrared positioning signal and carrying out calculates the transmission of the infrared positioning signal in each road
It is no after all infrared positioning signals are sent: if it is not, then continuing the adjustment of sending time.
And the free time in Fig. 2 between each infrared signal transmission, i.e. Time 5, Time 6, Time7 and Time 8
The error in adjustment and treatment process is allowed for, so that each signal transmission process does not conflict with each other interference.
Another method for effectively avoiding conflict is to be implanted into wireless communication module, such as bluetooth, Wi-Fi in charging pile
And ZigBee etc., the infrared signal transmit cycle on both sides is synchronized with wireless communication, as Indoor Robot completes infrared anti-collision letter
Number transmission after the order for opening infrared positioning signal is sent to charging pile by wireless communication, to notify charging pile not emit
Infrared positioning signal, then Indoor Robot retransmits the order for closing infrared positioning signal after charging complete, and starts to carry out red
The transmission of outer anticollision signal is periodically carried out to scan, and also can reach the effect for avoiding conflict.
Invention is the advantage is that the infrared positioning signal of alternately charging pile is sent and the infrared anti-collision of Indoor Robot is believed
Number send so that during automatic homing also can smooth Infrared anticollision function: kept away during periodicity sending
Exempt from stored counts error, the adjustment of sending time is carried out every several periods, avoid the overlapping of two sides transmission: using channel radio
The open and close control that letter mode carries out infrared positioning signal also avoids the accumulation of charging pile and Indoor Robot in timing
Error, to avoid conflicting.
