Embodiment
Below, illustrate to be used to implement most preferred embodiment of the present invention.
Fig. 1～Fig. 4 shows communication system and the distortion thereof of embodiment.Fig. 1 shows communication system and the environment for use thereof of embodiment, for example is, along running rail 4 instruction of two conveying trolley 2a, 2b waits from telepilot 12a, 12b is arranged.Here, the kind of conveying trolley is a track mounted jumbo, but also can be automatic guided vehicle or stakcer crane or overhead crane etc.And present embodiment is used for from telepilot by manually making the situation of conveying trolley work.
Conveying trolley 2a, 2b have Department of Communication Force 6 respectively, also have antenna 8 and infrared ray acceptance division 10 that radio communication is used respectively.Radio communication does not have directive property, and infrared communication has directive property, for example at 3 to 4 positions infrared ray acceptance division 10 is set, and can both receive from which orientation receiving infrared-ray no matter make.Have the antenna 14 that radio communication uses and the infrared ray sending part 16 of infrared communication in telepilot 12a, 12b side.
In Fig. 1,, there are two people to be ready utilizing telepilot 12a, 12b by manually communicating for example at two conveying trolley 2a, 2b being in the approximated position., have WLAN 18 etc. around herein, might and conveying trolley 2a, 2b and telepilot 12a, 12b between Communication Jamming.In addition, the treating apparatus 20 from other also might send the interference electric wave.In addition, when WLAN 18 or treating apparatus 20 disturbs communicating by letter between conveying trolley 2a, 2b and telepilot 12a, the 12b, owing to communication, also may disturb on the contrary in WLAN 18 or treating apparatus 20 sides from telepilot 12a, 12b etc.
Fig. 2 shows the structure of telepilot 12, and the 22nd, touch pad is overlapping forming such as LCD and pressure-sensitive switch, the 23rd, keyboard is not provided with passable yet.The 24th, the frequency switching part, it is stored in employed a plurality of frequencies in the radio communication with conveying trolley 2, and with the order switching frequency of regulation.In addition, timer 25 be calculate by infrared ray or wireless from telepilot 12 after conveying trolley 2 request feedback signals up to the time of actual reception to feedback signal.
Telepilot 12 just can detect interference has taken place in radio communication if can not receive the feedback signal that meets necessary form in official hour.Specifically, if timer 25 before receiving from the wireless signal of conveying trolley 2 just then, then frequency switching part 24 just switches the employed frequency of radio communication.Like this, can detect the interference whether the radio communication degree has taken place to hinder simple and reliablely.In addition, the detection method of interference itself is arbitrarily.
In conveying trolley 2 sides, except a plurality of infrared ray acceptance divisions 10 and antenna 8, also be provided with communication cpu 26, be used for communicating by letter with telepilot 12.Result of communication is transmitted to host CPU 28, with control conveying trolley 2.Frequency switching part 29 switches the oscillation frequency of oscillation circuit 30 according to the frequency that communicates with infrared communication from telepilot 12, thereby switches wireless communication frequency.
Fig. 3 shows the frequency meter 32 of storage in frequency switching part 24.In frequency meter 32, for example store n frequency exclusive, that in other words between telepilot, can not repeat in each telepilot 12.N is for example about 2～5.In this case, in the frequency switching part 29 of conveying trolley 2 sides, store a plurality of telepilot 12 employed all wireless communication frequencies.
From telepilot 12 when conveying trolley 2 communicates, at first specify the numbering of employed wireless frequency in the ID of the numbering of the chassis that will communicate by infrared communication or chassis and the communication or wireless frequency.Because wireless frequency is that each telepilot is exclusive, so for example specify the ID of telepilot and the numbering of the frequency in this telepilot.Because infrared communication has directive property,, can not received by other conveying trolleys 2b so, can only be handled upside down chassis 2a from the infrared communication of telepilot 12a yet and receive even in the such environment of Fig. 1.And, in conveying trolley 2a side, use appointed frequency to send feedback signal from antenna 8 by radio communication.Later communication is undertaken by radio communication with appointed frequency.
In an embodiment and since radio communication in employed frequency be that each telepilot 12 is exclusive, so not can and other telepilots between disturb.But, disturb between meeting and WLAN 18 or other treating apparatus 20.In this case, from telepilot 12 sides, exactly in the stipulated time that timer 25 is counted, can't receive normal feedback signal.Such situation as the situation that has taken place to disturb, and is assigned to conveying trolley 2 by the frequency that infrared communication is used next radio communication.Therefore, communicate once more at conveying trolley 2 side switching frequencies.
Because the situation that n wireless frequency of storage all disturbs in the telepilot 12 is very rare, so can carry out normal radio communication with a certain frequency.In other words, by using infrared communication, can prevent communicating by letter between the conveying trolley with non-appointment.Because by the frequency of infrared communication specific radio communication, and each telepilot frequency of using exclusive radio communication to use, so can prevent interference between telepilot.And, by the switching of frequency can avoid and other treating apparatus or WLAN between interference.
If the exclusive wireless communication frequency of storage then can prevent the interference of 12 of telepilots, but in conveying trolley 2 sides, then need to store more frequency in each telepilot.Therefore, represented variation in Fig. 4, this variation is when taking place between telepilot with initial specified frequency to disturb, and can avoid interference by switching frequency.In this variation, can reduce quantity in the frequency of conveying trolley 2 sides storage.
41, the new frequency meter of 42 expressions, its group of frequencies of storing is general 12 of telepilots, but the storage order difference of frequency.In variation, the order that makes employed frequency in the radio communication is exclusive getting final product in each telepilot, and it is exclusive in each telepilot that this example makes storage order.It is exclusive that each telepilot uses the order of which frequency, that is, what the frequency of storing in the table 41,42 use in order for each telepilot according to is different.In conveying trolley 2 sides, because table 41,42 frequency are general, so can reduce the quantity of the frequency of being stored.
Under the situation of Fig. 4, specify the numbering of chassis and the numbering of employed frequency by infrared communication with telepilot.Telepilot is waited for the wireless feedback signal from conveying trolley, if can normally receive then at timer 25, so just carries out radio communication with this frequency.If timer 25 just then before receiving normal feedback signal, then according to table 41,42 switching frequencies.At this, because the order of employed frequency is that each telepilot 12 is exclusive in the communication, so even specified identical frequency at first between the hypothesis telepilot situation about disturbing has taken place, the probability that generation is disturbed when switching to next frequency is also very little.Like this, can avoid interference between telepilot.In addition, and WLAN 18 or other treating apparatus 20 etc. between under the situation about take place disturbing, also can prevent to disturb by switching frequency.
In an embodiment, can access following effect.
(1) because to communicate, so interference is possible little from the telepilot specified frequency.Certainly, do not need by the manual operation program switch.
(2) if each telepilot uses exclusive wireless frequency, the interference between telepilot can not take place then.
(3) as if the order difference of the frequency of using in telepilot chien shih switching radio communication,, also can avoid interference by switching frequency even then interference has taken place hypothesis.
(4) if storage multiple in communication employed frequency and switching successively, then can prevent and WLAN or other treating apparatus etc. between interference.
Show the example of storing frequencies in table 32,41,42 in an embodiment, store in the branch week of clock frequency for example, in addition, also can carry out hardware store based on frequency setting electricity capacity etc. than waiting but frequency also can be used as.
