Embodiment
Clearly understand to make object of the present invention, technical scheme and advantage, below in conjunction with accompanying drawing to multiterminal communication means, device, system based on radio frequency transmission of the present invention, and being described from the embodiment of machine communication means, device based on radio frequency transmission.Should be appreciated that specific embodiment described herein only in order to explain the present invention, be not intended to limit the present invention.
Multiterminal communication means based on radio frequency transmission of the present invention, is mainly applied in the main frame of multiterminal communication system of radio frequency transmission, for main frame and from the communication between machine.
It will be understood by those skilled in the art that based in the multiterminal communication system of radio frequency transmission, multiple equipment can be related to, and the transmission of signal and control each other can be carried out by radio frequency between multiple equipment.Of the present invention based in the multiterminal communication means of radio frequency transmission, whole based on the multiterminal communication system of radio frequency transmission in be provided with a main control device, the main frame namely described in the inventive method.And other equipment in system are all defined as from machine.Namely, of the present inventionly to refer to based on said main frame in the multiterminal communication means of radio frequency transmission, in based on the multiterminal communication system of radio frequency transmission, be in master control status, can carry out by RF technology and other equipment in system the equipment that communicates.Then refer to from machine, in based on the multiterminal communication system of radio frequency transmission, be not in master control status, but can by the equipment of radio frequency and main-machine communication.
Particularly, wherein in an embodiment based on the multiterminal communication means of radio frequency transmission, as shown in Figure 1, comprise the following steps:
S100, preset public frequency on receive from machine send from the machine communication information.
Step S100 can be described as the first step in embodiment of the present invention method, and after starting based on the multiterminal communication system energising of radio frequency transmission, first each equipment in system can operate on a default power.And the transmission of signal is carried out by this public frequency.Now, the main frame running embodiment of the present invention method can search for the information sent from machine received on public frequency, is generally the communication information that the requirement of sending from machine establishes a communications link.Some code informations from machine self are generally comprised, so that main frame can be distinguished each from machine according to the communication information sent from machine received in these information.
It should be noted that, described default public frequency generally can be set to a certain fixing frequency.Based on equipment such as each smart electronics products in the multiterminal communication system of radio frequency transmission after power-on initialization, under all first operating in this frequency.But preferably, a certain frequency band also can be selected as described public frequency.Now, system energization run after, main frame can search for receive in this band frequency ask from confidential the information established a communications link.
S200, distribute corresponding communication frequency give from the machine communication information corresponding from machine.
According to the description of step S100, system energization run after, each from machine can send require establish a communications link from the machine communication information to main frame.So, each from the machine communication information can corresponding one from machine, main frame also can be corresponding from machine according to determining from machine information of comprising from the machine communication information.Thus, main frame can determine each from the machine communication information corresponding from machine, and distribute a specific communications frequency from machine for each.Each communication frequency i.e. a corresponding frequency, after determining communication frequency, then should can carry out radio communication under this frequency and between main frame from machine.
A general communication frequency only corresponding one from machine, namely from machine correspondence, there is a distinctive communication frequency based on each in the multiterminal communication system of radio frequency transmission.Thus realize multiple between machine and main frame, and one is communicated from the multiterminal between machine with other from machine by main frame, and can completely interference-freely carry out each other.
It should be noted that, at some in particular cases, also there will be multiple situation of distributing same communication frequency from machine, many from machine as access, and exist two or several liveness lower from machine time.In this case, same communication frequency from machine be sent to main frame information can by main frame by setting agreement distinguish.Such setting can reduce the quantity of communication frequency simultaneously active in main frame, thus reduces main frame to the speed of the information retrieval sent from machine, transmission.During the operation such as the mode circulated in order as main frame receives the mode of carrying out poll from machine information, pass on, main frame and the quantity from the communication frequency participated between machine directly affect the efficiency of main frame to the message of sending from machine.Certainly, in this case to liveness higher still can distinguish the different communication frequency of frequency division from machine, to process from machine information fast.
S300, according to communication frequency and from the corresponding relation between machine, corresponding communication frequency communicates from machine with corresponding.
Two steps set up main frame and after the communication between machine, then main frame can communicate normally with between machine above.Main frame communicates from machine from different by redirect operating frequency.Such as, main frame can be corresponding with A communication frequency on A communication frequency communicate from machine A, and with after machine A sign off, main frame can carry out the conversion of operating frequency, jump to the work such as the collecting of information that B communication frequency carries out, transmission, then now main frame can send message to corresponding with B communication frequency from machine B, and the message that acceptance is sent from machine B.
The multiterminal communication means based on radio frequency transmission of the embodiment of the present invention, it is set up and multiple communication connection between machine by arranging public frequency, and by distributing different communication frequencys to set up and each from the independent communication port between machine from machine to difference.Adopt in this way, can make respectively do not have noisy carrying out from the communication between machine and main frame.And main frame and respectively just being distinguished from the communication between machine by communication frequency, without the need to arranging complicated agreement support in main frame, improve main frame and each efficiency from communicating between machine, shortening host process is from the time of machine information.And adopt this multiterminal communication mode, support more from machine quantity by a fairly large number of communication frequency reserved in main frame, be convenient to very much the expansion of port (from machine) quantity.
As a kind of embodiment, in step S300, according to communication frequency and from the corresponding relation between machine, corresponding communication frequency communicates from machine with corresponding, specifically comprises the following steps:
S310, sorts to communication frequency according to preset order, obtain with carry out communicating from machine from machine communication sequence.
S320, carries out radio communication with corresponding from machine according to from machine communication sequence on corresponding communication frequency.
Wherein, the preset order sorted to communication frequency can for directly to sort according to the size of communication frequency, as sorted according to communication frequency order from small to large or from big to small.What sort is distributed respectively to the communication frequency respectively from machine herein, and after sequence, then main frame can communicate in order one by one with from machine according to this order.Certainly, generally to respectively from after machine carries out communication frequency distribution, in main frame, also can retain a part of unappropriated communication frequency or communication frequency section, new when machine adds communication, distribute new communication frequency to have.It will be understood by those skilled in the art that main frame is when initialization, its inside is the communication frequency storing relatively large Gong distribution or use.
In other embodiments, in main frame, be previously stored with the preset order of each different communication frequency (all communication frequencys to be allocated), as stored the order of each communication frequency with the form of sequence list.And main frame is when allocate communications frequency, can according to the time sequencing received on public frequency from the machine communication information or the default distribution carrying out communication frequency from machine communication priority.As the front and back according to time of reception, the communication frequency forward from machine allocation order table that the communication information first received is corresponding, after communication frequency rearward from machine allocation order table corresponding to the communication information that receives.Or from the machine allocation order table forward communication frequency high to priority, from the machine allocation order table communication frequency rearward low to priority.
And main frame is when allocate communications frequency, not necessarily distributes one by one in strict accordance with the order in communication frequency sequence list.After the communication frequency made number one as distributed, the 5th or the 7th communication frequency may be distributed to the next one from machine.Certainly, also completely can in strict accordance with the order in sequence list one by one allocate communications frequency give each from machine.After main frame often distributes a communication frequency, can the frequency of having distributed be marked, to select suitable communication frequency to distribute during lower sub-distribution in unappropriated communication frequency.
Better, as a kind of embodiment, after main frame completes the process once receiving information on public frequency, carry out concrete communicate with from machine before once can integrate all unappropriated communication frequencys.As calculated the quantity etc. of the communication frequency that can also provide.And can rebuild remaining can new communication frequency sequence list corresponding to allocate communications frequency, to use when distributing from machine next.
Also it should be noted that, as shown in Figure 2, main frame is with when communicating from machine, and it can be that the mode circulated in order is carried out.As shown in Figure 2, if based on containing n in the multiterminal communication system of radio frequency transmission from machine, be respectively from machine 1, from machine 2, from machine 3 ..., from machine n, and suppose the order according to communication frequency, main frame is exactly according to from machine 1, from machine 2, from machine 3,, from the order of machine n successively with carry out communicating from machine.So, in the invention process, main frame and from the communication formally between machine after, first main frame can receive at the communication frequency 1 corresponding with from machine 1 radio-frequency information sent from machine 1, or send information to from machine 1.And main frame with from machine 1 or when communicating from machine with other, main frame and from having the mechanism of answer between machine, confirms whether the other side receives information.As shown in Figure 2, adopt the method for the embodiment of the present invention to carry out main frame and from communication between machine time, only have main frame and complete from the communication between machine 1, main frame just can frequency hopping communicate to from corresponding communication frequency 2 continuation of machine 2 with from machine 2.The complete confirmation of communication shown in figure can send ending message for sending to from machine the information of main frame, or without information, or the equipment stand-by period reaches the information such as the upper limit.Main frame in order, finally to complete and after the communication between machine n, frequency hopping can return communication frequency 1 and again with from machine communicate, and so carries out moving in circles constantly respectively carrying out long-range radio-frequency from machine with n and communicating.
In order to more timely to processing from machine of newly adding, wherein in an embodiment, main frame often complete once and one after the communication between machine, all perform and receive the step from the machine communication information of sending from machine on the public frequency preset, and according on public frequency new receive from the machine communication information, distribute corresponding communication frequency to correspondence newly adding of answering from machine.
Concrete, as shown in Figure 3, main frame with communicate from machine after, complete once and from the communication between machine at every turn, jump on public frequency and carry out collecting of information, namely search for new for machine, if detect new for machine, then be from machine allocate communications frequency, and return continuation and communicate with from machine; If do not detect new for machine, then return and continue to communicate with from machine.
It should be noted that, determine newly to add after machine, the quantity of the communication frequency distributed can increase accordingly, therefore, the communication frequency newly added can be re-started sequence by main frame together with original communication frequency, and can continue to adopt the mode of poll to communicate one by one with from machine according to new sequence.But, newly join communication ranks from machine even if having, main frame and also proceeding from the communication between machine, instead of return and re-start communication from first machine communication list from machine.As, newly add one after machine, be increased to n+1 from the skilled of machine by original n.If this is stylish add from machine former after machine 2, before machine 3, and to search new be that main frame completes and carries out from the communication between machine 3 from machine.So, after main frame is given and is newly distributed communication frequency from machine, can continue to jump to and originally carry out (not increasing newly from before machine with carrying out from machine 4 communicating from the communication frequency 4 of machine 4 correspondence, main frame and be according to from machine 1 from the communication between machine, from machine 2,, carry out to the order from machine n).Now, newly once communicate with main frame in cyclic process on main frame from chance.But, if just coming from machine of newly adding is original after machine 3, before machine 4, then can communicate from machine immediately with newly after the complete communication frequency of host assignment.
In other embodiments, main frame is not often complete once and all jump to public frequency from the communication between machine to carry out newly from the search of machine, but often complete once existing all after the communication cycles of machine, just redirect once can arrive public frequency, to processing from machine of newly increasing.Certainly, add new after machine, main frame once can adjust the order from machine communication too, resets.
It will be understood by those skilled in the art that and also can set completing to communicate from machine and carrying out once the new search work from machine of main frame and predetermined number as required.As often complete and two after the communication between machine, jump to public frequency and carry out once the new search from machine.No matter adopt which kind of mode to carry out newly from the search of machine, if find do not have new adding from machine, certainly, main frame all can continue to communicate with from machine according to the order of original communication frequency.
For the multiterminal communication means based on radio frequency transmission of the present invention, when one from confidential with other communicate from machine time, second to be sent a message to from machine (from machine B) as first from machine (from machine A).As shown in Figure 4, first can first will send to when main frame is communicated with it by communication frequency A from machine (from machine A) and send to main frame from the message of machine B; After main frame receives the message of sending from machine A, can judge message, judge it is send to after the message of machine B when it, it temporarily can store this message, until main frame jumps to from communication frequency B corresponding to machine B with when communicating from machine B according to the order of communication frequency, previously stored will to be sent to from machine A just can be transmitted to from machine B from the message of machine B by main frame.
For main frame to each from machine send the judgement of message, certainly or certain host-host protocol support can be needed, respectively send to the information of main frame from machine and can comprise necessary address or from information such as machine codes.
