In addition, relay test section 203 by it is in the control device 1 detected as candidate device, in addition to being determinedIt is set to some or all of the control device 1 other than the control device 1 of relay, is decided to be relaying dress as being inferior toThe second relay that the control device 1 set preferentially is communicated is (hereinafter referred to as " instead of relay ".).For example, schemingIn the case where the example of 6A, relay test section 203 is some or all by control device [2]~control device [n]It is determined as replacing relay.
Relay test section 203 makes the relay for indicating to determine in this way and replaces the relay of relayInformation is stored in internal storage region.For example, relay information is stored as relay shown in Fig. 6 B and Fig. 6 CTable 310 and replacement relay table 320.
Fig. 7 is the first action example of the processing for indicating that relay relays control message in the 1st embodimentFigure.In action example shown in Fig. 7, control device 1-11 is detected as relay by terminal installation 2.In addition, schemingIn 7, control device [12] corresponds to control device 1-12.For example, in this case, the generation of terminal installation 2 includes to control device1-12 indicates the control message M1 for the control information (starting of air conditioner) that the power supply of air-conditioning equipment is connected.At this point, terminal installation 2 is logicalCrossing makes the payload of control message M1 include control information and assigns payload based on terminal installation 2 and control device 1Between communication protocol header (hereinafter referred to as " the 1st protocol header ".), Lai Shengcheng control message M1.
The transmission of address MAC (Media Access Control) of destination is sent in 1st protocol header comprising expressionThe transmission source MAC of destination MAC Address and the MAC Address of expression transmission source.In the case where the action example of Fig. 7, to hairThe MAC Address " XX:XX:XX:AA " for sending destination MAC Address to set control device 1-11 is set to source MAC is sentThe MAC Address " XX:XX:XX:RR " of terminal installation 2.
The control device 1-11 for receiving control message M1 is turned control message M1 by executing the first relay processIt is changed to the corresponding control message M2 of communication protocol between control device 1.Specifically, control device 1-11 will be to receivingControl message M1 assign the 1st protocol header be converted to the header based on the communication protocol between control device 1 (hereinafter referred to as" the 2nd protocol header ".).It is same as the 1st protocol header, it include sending destination MAC Address and transmission source in the 2nd protocol headerMAC Address.In the case where the action example of Fig. 7, the MAC Address of control device 1-12 is set to transmission destination MAC Address" XX:XX:XX:DD " sets the MAC Address " XX:XX:XX:AA " of control device 1-11 to transmission source MAC.Turn in this wayControl message M2 after changing as the control device 1-12 for sending destination by receiving.
Fig. 8 is the second action example of the processing for indicating that relay relays control message in the 1st embodimentFigure.Fig. 7 illustrates the case where direct controlled device 1-12 of control message relayed by control device 1-11 is receivedAction example, in contrast, Fig. 8 shows the control messages after being relayed by control device 1-11 via other control systems 1-13 quiltThe action example for the case where control device 1-12 is received.
In this case, by executing the first relay process, the control message M1 received is converted by control device 1-11For control message M2 '.At this point, in the 2nd protocol header that the 1st protocol header of replacement is given to payload, in addition to hairIt send destination MAC Address and sends other than source MAC, further include the destination MAC for indicating the MAC Address of destinationThe MAC Address that location and expression transmit source transmits source MAC.Wherein, " transmitting source " mentioned here refers to, according to shouldThe generation of the control information of transmission and the node for having carried out generation and the transmission of control message.That is, in the action example of Fig. 8,Terminal installation 2 becomes the node in the source that transmits.In contrast, " transmission source " refers to, the sending side of the two directly received and dispatchedNode.The record of " transmitting source " below and " transmission source " refers to above-mentioned difference.
In the case where the action example of Fig. 8, the control for sending destination MAC Address and transmission source MAC and Fig. 7 disappearsBreath M2 is similarly set, and the MAC Address " XX:XX:XX:DD " of control device 1-12 is set to destination MAC Address, to hairInformation source MAC Address sets the MAC Address " XX:XX:XX:RR " of terminal installation 2.In addition, control device 1-11 is based on net at this timeThe transmission destination of the agreement of grid network, the case where capable of being identified as with control device 1-12 as a purpose is control device1-13.Control message M2 ' after converting in this way as the control device 1-13 for sending destination by receiving.
The control device 1-13 for receiving control message M2 ', by executing the second relay process, the control that will receiveIt is the control message M2 " for sending destination that message M2 ' processed, which is converted to control device 1-12 as a purpose,.Specifically,Control device 1-13 by the transmission source MAC of control message M2 ' is changed to the present apparatus MAC Address " XX:XX:XX:BB ", the MAC Address " XX:XX:XX:DD " that transmission destination MAC Address is changed to control device 1-12 as a purpose,To generate control message M2 ".Control message M2 " after converting in this way by (and send destination) as a purpose control device1-12 is received.
Fig. 9 is to indicate that control device 1 responds one for having sent the terminal installation 2 of control message in the 1st embodimentThe timing diagram of the process of the processing of secondary ACK and secondary ACK.Firstly, terminal installation 2 is for the control device as relay[1] control message (step 301) is sent.Control device [1] responds one for terminal installation 2 according to the reception of control messageSecondary ACK (step S302).If responding an ACK, control device [1] ensures for the mesh from the control message receivedThe region ACK (step S303) that is stored secondary ACK that responds of ground, that is, control device 1.
If the ensuring that the region ACK, then control device [1] is by the control message received to the control device 1 of destinationRelayed (step S304).Here, it is contemplated that the case where control device 1 of destination is control device [4].In this case, controlUntil message processed is transferred to the control device [4] of destination according to the transfer path of grid network.For example, from control device[1] control message sent can directly be received by the control device [4] of destination, can also pass through other control systems 1Second relay process and be transferred to destination control device [4] until.
Control device [4] is according to the reception of control message, to respond ACK (step for the terminal installation 2 for transmitting sourceS305).The ACK sent from control device [4] is transferred to and fills with the terminal of destination according to the transfer path of grid networkSet 2 control devices [1] being connected to.Here, each control device 1 is capable of the terminal installation 2 on identifying purpose ground and which control fillsSet 1 connection.For example, each control device 1 can be carried out extensively by the link information for the terminal installation 2 connecting to expression with the present apparatusIt broadcasts to notify to the other control systems 1 in grid network.
In addition, for example in the case where the control device 1 as relay receives control message from terminal installation 2,The relay can be to including that itself the control message of identification information relays.In this case, to the control messageThe other control systems relayed, identification information based on relay and transmit source MAC, to learn to fill as relayingThe corresponding relationship of the control device 1 and terminal installation 2 set.
What control device [1] reception was sent from control device [4] is the ACK of destination with terminal installation 2.Control device[1] information of the ACK received will be indicated as secondary ack msg, storage to the region ACK ensured in step S303(step S306).
On the other hand, terminal installation 2 comes according to the reception of the ACK sent in step s 302 from control device [1]Set ACK inquiry timer (step S307).ACK inquiry timer is that relay is inquired to terminal installation 2 to standbyTime until the reception of secondary ACK carries out the timer of timing.By the setting of the secondary ACK timer, start from receptionACK plays the timing of the time until the reception for inquiring secondary ACK for relay standby always.If setting twoSecondary ACK timer, then terminal installation 2 makes the present apparatus migrate state (hereinafter referred to as " the suspend mode shape to have stopped to the function of a partState ".) (step S308).
The dormant state started in step S308 continues until secondary ACK timer expired.On the other hand, secondaryACK timer is overtime in subsequent step S309.Therefore, phase of the terminal installation 2 until until secondary ACK timer expiredBetween, dormant state is moved to, thus, it is possible to be acted with electricity-saving state.
If secondary ACK timer expired, terminal installation 2 revert to usual state from dormant state.Terminal installation 2According to the recovery to usual state, to request the control device [1] as relay the transmission to the secondary ACK of the present apparatus(step S310).Control device [1] sends the reception of request according to secondary ACK, obtains from the region ACK and is filled with the terminal of request source2 are set as the secondary ack msg of destination.Control device [1] is filled based on acquired secondary ack msg come the terminal to request sourceSet the secondary ACK (step S311) of 2 transmissions.Control device [1] will be stored with the secondary ack msg when having sent secondary ACKThe region ACK discharges (step S312).
In addition, in the action example of Fig. 9, due to the exception of control device [4] etc., it may occur however that receiving terminal installationAt the time of 2 secondary ACK sends request, control device [1] is not received by the situation of the ACK sent from control device [4].It shouldIn the case of, control device [1] responds to be not received by with the terminal installation 2 as destination the terminal installation 2 of request sourceSecondary ACK.In addition, in this case, secondary ACK, which can be repeated, in terminal installation 2 sends request until obtaining secondary ACK'sUntil response.In this case, terminal installation 2 can be repeated on one side by setting secondary ACK timer again to suspend modeSecondary ACK is repeated on one side and sends request for the transfer of state and recovery to usual state, can also be not moved to dormant stateGround is repeated secondary ACK and sends request.In addition, can not the secondary ACK that stipulated number is repeated sends request yetIn the case where the response for obtaining secondary ACK, terminal installation 2 can be filled the control message having sent in step S301 to control[1] is set to send again.
Figure 10 is the third action example for the processing for indicating that relay relays control message in the 1st embodimentFigure.Figure 10 is illustrated about the control message (hereinafter referred to as " group control message " sent by group transmission unit 212.) relaying atThe summary of reason.In this case, it includes indicating that control device 1-12, the control of the stopping of air-conditioning equipment is believed that terminal installation 2, which generates,The group control for the control information (starting of air conditioner) that breath (air-conditioning closing) is connected with the power supply to control device 1-13 instruction air-conditioning equipmentMessage M processedG1.At this point, terminal installation 2 is by making payload include the control letter for control device 1-12 and 1-13It ceases and assigns identical with Fig. 7 or Fig. 8 the 1st protocol header to payload, next life control message M in groupsG1。
Receive a group control message MG1 control device 1-11 will include being directed to by executing the first relay processThe group control message M of the control information of multiple destinationsG1 be converted to only include each destination (i.e. control device 1-12 andThe control message M2 of control information 1-14)1And M22.Specifically, firstly, the group control that control device 1-11 will be receivedMessage M processedG1 is converted to the control message of each destination of multiple destinations.By the conversion, control message M is organizedG1 is turnedIt is changed to including control information C1Payload impart the 1st control message M1 of the 1st protocol header H11It is (not shown) and rightIncluding controlling information C2Payload impart the 2nd control message M1 of the 1st protocol header H12(not shown).
Control device 1-11 passes through to based on group control message MGControl message M1 obtained from 1 conversion1And M12PointThe first relay process is not executed, will be given to control message M11And M12The 1st protocol header H1 be converted into and respective meshThe corresponding 2nd protocol header H2 in ground1And H22.Pass through the conversion, the 1st control message M11It is converted into control message M21,2nd control message M12It is converted into control message M22。
At this point, to control message M21The 2nd protocol header H2 assigned1In, to transmission destination MAC Address and purposeGround MAC Address sets the MAC Address " XX:XX:XX:BB " of control device 1-12.On the other hand, to control message M22It assignsThe 2nd protocol header H2 given2In, control device 1-13 is set to transmission destination MAC Address and destination MAC AddressMAC Address " XX:XX:XX:DD ".
Moreover, because control message M21And M22All be the source that transmits be terminal installation 2, transmission source is control device 1-11, so in the 2nd protocol header H21And H22Some in, all to sending source MAC setting control device 1-11MAC Address " XX:XX:XX:AA ", to the MAC Address " XX:XX:XX:RR " for transmitting source MAC setting terminal device 2.Pass throughThe control message M2 of such conversion and generation1And M22By as the control for sending destination (being equal to destination in this case)Device 1-12 and 1-13 processed is received respectively.
Figure 11 is to indicate that control device 1 is responded for having sent the terminal installation 2 of group control message in the 1st embodimentThe timing diagram of the process of the processing of ACK and secondary ACK.Wherein, by everywhere in shown in Figure 11 in reason with Fig. 9 phaseSame processing imparting and the identical appended drawing reference of Fig. 9, thus omits explanation here.Firstly, 2 pairs of terminal installation fill as relayingControl device [1] the transmission group control message (step S401) set.Here, in transmitted group control message for example including being directed toThe control information of control device [2] and control device [4].In this case, control device [1] is by executing at the first relayingThe group control message received, is converted to each control device for control device [2] and control device [4] by reasonEach control message.Hereinafter, by control message [2] are recorded as the control message of control device [2], it will be for control dressThe control message for setting [4] is recorded as control message [4] to be distinguished.
Control device [1] sends control message [2] (step S402) so that control device [2] are destination, to control dressSetting [4] is destination to send control message [4] (step S403).Control device [2] according to the reception of control message [2] come pairTerminal installation 2 in the source that transmits responds ACK (step S404).Equally, control device [4] comes according to the reception of control message [4]Terminal installation 2 for transmitting source responds ACK (step S405).Hereinafter, the ACK responded from control device [2] is recorded as ACK[2], the ACK responded from control device [4] is recorded as ACK [4].
In this case, the control device [1] of the transmission request of secondary ACK is received from terminal installation 2 in step s310,The ACK [2] and ACK [4] received as the response for terminal installation 2 is obtained from the region ACK, and will be acquiredACK [2] and ACK [4] sends (step S406) to the terminal installation 2 of request source as secondary ACK.
In the apparatus control system 100 of the 1st embodiment constituted in this way, according to the control sent from terminal installation 2The reception of message to send an ACK to terminal installation 2, to 1 sound of other control systems from the destination as control messageThe secondary ACK answered is temporarily stored.Then, request of the control device 1 according to terminal installation 2, two will temporarily stored by the present apparatusSecondary ACK is sent to the terminal installation 2 of request source.By having such composition, terminal installation 2 can be from receiving an ACKIt rises during until requesting secondary ACK, the present apparatus is made to move to dormant state.Therefore, terminal installation 2 can be moved to than previousProlonged dormant state can be further reduced consumption electric power.
(the 2nd embodiment)
Figure 12 is the block diagram for the concrete example for indicating that the function of the terminal installation 2a in the 2nd embodiment is constituted.Wherein, Figure 12Shown in control device 1 it is identical as the control device 1 of the 1st embodiment.The terminal installation of terminal installation 2a and the 1st embodiment2 the difference lies in that having suspend mode control unit 205a this point instead of suspend mode control unit 205.
Other than suspend mode control unit 205a function possessed by the suspend mode control unit 205 in the 1st embodiment, also haveIt is changed according to the reception situation of secondary ACK from receiving an ACK during until carrying out the transmission request of secondary ACKDormancy time function.
Figure 13 is the first timing for indicating the process of the processing of terminal installation 2a change dormancy time in the 2nd embodimentFigure.Firstly, terminal installation 2a sends control message (step S501) to control device [1].Control device [1] is according to control messageReception, for terminal installation 2a respond an ACK (step S502).Control device [1] is if respond terminal installation 2aACK, then relayed (step S503) to control device [4] as a purpose for the control message received.ControlDevice [4] processed is according to the reception of control message, to send the secondary ACK (step for being directed to the terminal installation 2a as the source that transmitsS504).The secondary ACK sent from control device [4] is stored in the region ACK by control device [1].
On the other hand, terminal installation 2a makes the present apparatus move to dormant state (step S505) according to the reception of an ACK.For example it is assumed that being 10 seconds for dormancy time here.If have passed through 10 seconds dormancy times, terminal installation 2a is for controlDevice [1] requests the transmission (step S506) of secondary ACK.Control device [1] sends the reception of request according to secondary ACK, will(step S507) is sent from the secondary ACK that control device [4] receives to the terminal installation 2a of request source.Terminal installation 2a's stopsDormancy control unit 205a shortens dormancy time (step S508) according to secondary ACK this case is normally received.
The example of Figure 13 illustrates suspend mode control unit 205a by the time after subtracting the unit time from current dormancy timeThe example of dormancy time as next time.In this case, the unit time can be preset fixed value, rule can also be passed throughFixed calculating formula calculates.In addition, the unit time can also be selected from multiple candidates based on defined condition.Here, notDormancy control unit 205a and subtracting preset unit time " 1 second " from current dormancy time by next suspend mode whenBetween be determined as " 9 seconds ".
Then, if producing the new control information for control device [4], terminal installation in terminal installation 2a2a generates the control message sent to newly generated control information.Terminal installation 2a is by control message generated to controlDevice [1] sends (step S509).Then, by executing processing identical with step S502~S507, terminal installation 2a is rungIt should be for the secondary ACK (step S510~S515) of the control message sent in step S509.
At this point, in step S513, terminal installation 2a moves to dormant state when being the suspend mode after shortening in step S505Between.The example of Figure 13 illustrates that terminal installation 2a determines 9 seconds from original dormancy time that is, obtained from subtracting within 10 seconds 1 secondFor the example of new dormancy time.In this case, terminal installation 2a moves to dormant state according to the reception of an ACK, passing throughThe transmission that control device [1] requests secondary ACK is directed to after the dormant state for having spent 9 seconds.
Figure 14 is the second timing for indicating the process of the processing of terminal installation 2a change dormancy time in the 2nd embodimentFigure.Figure 13, which is illustrated according to secondary ACK this case is received, shortens the process of the processing of dormancy time, in contrast, figure14 indicate according to the process for being not received by this case that secondary ACK the processing for extending dormancy time.Wherein, by Figure 14Processing same as figure 13 everywhere in shown in reason assigns appended drawing reference same as figure 13 to omit explanation here.
Figure 14 and Figure 13's the difference lies in that the secondary ACK having sent in step s 507 not by terminal installation 2a justOften receive.In this case, suspend mode control unit 205a extends dormancy time to make secondary ACK send the opportunity delay of request(step S601).
The example of Figure 14 illustrate suspend mode control unit 205a by current dormancy time added after the unit time whenBetween as next time dormancy time example.Here, suspend mode control unit 205a is set in advance by adding to current dormancy timeNext dormancy time is determined as " 11 seconds " by the fixed unit time " 1 second ".In this case, terminal installation 2a is according to primaryThe reception of ACK and move to dormant state, after it have passed through 11 seconds dormant states for control device [1] request it is secondaryThe transmission of ACK.
In the apparatus control system 100 of the 2nd embodiment constituted in this way, terminal installation 2a connects according to secondary ACK'sReceipts situations changes dormancy time.The adjustment of dormancy time in this way, can be by the length of the dormancy time of terminal installation 2aDegree is adjusted to length appropriate.
Hereinafter, being illustrated to the variation of the apparatus control system 100 of embodiment.
Relay test section 203 is also configured in the number that send again of control message be more than the upper limit of stipulated numberIn the case where execute the detection of relay again.
Message transmission unit 204 is also configured to, in the case where not receiving an ACK, with pre-determined regulationNumber send transmitted control message as the upper limit again.
Message transmission unit 204 may be also constructed to, and be more than the upper limit of stipulated number in the number that send again of control messageIn the case of, relay will be replaced to send control message again as destination is sent.
Suspend mode control unit 205a is also configured to, and rule have been repeated in the shortening and extension of the length of dormancy timeIn the case where determining number, unit time when will shorten or lengthen the length of dormancy time shortens.
Suspend mode control unit 205a may be also constructed to, and rule have been repeated in the shortening and extension of the length of dormancy timeIn the case where determining number, by the length of dormancy time be fixed as the moment length and later without change.
At least one embodiment from the description above will be disappeared by including control device for the control receivedThe first of breath receives response and sends to terminal installation and send the control being expressed as by destination according to the request of terminal installationDevice processed receives the second reception response of control message；And terminal installation, from reception first receive response until receiveSecond receive response until during specified time limit, so that the function of a part of the present apparatus is stopped, thus equipment control relate toAnd cordless communication network in can be realized the economize on electricity of wireless device.
