Technical field
The present invention relates generally to Lighting Control Assembly.Particularly, the present invention relates to the Lighting Control Assembly that interconnects, wherein these Lighting Control Assemblies are worked with identical radio frequency (RF).More specifically, the present invention relates to be used for the equipment and the method for this interconnection.
Background technology
Can utilize combination at the predetermined light fixture of level works such as predetermined light intensity to realize that illumination uses.For example, residential lighting is used may need multiple illumination situation or " scene ".First kind of scene may be that the resident is needed when movable when being in and in the room.In this scene, mobile safely to be implemented in the room at the light of each position irradiation full strength.Second kind of scene may be needed when the resident goes out.For example, for safety or other reasons, outdoor light and room light may shine with different intensity grades.Equally, the scene that can dispose other be used for that the resident spends a holiday, amusement or carry out the activity of any other type.Along with the increase of light fixture and/or scene, controlling light fixture rather than control each light fixture separately from middle position will be more easily.
In using, illumination has the multiple system that can realize to the light fixture remote control.Wireless illumination control is commonly used in dwelling house and commercial the application because it compare with wired system install easily and cost low.Wired system is because of needing the hard wire lighting control equipment to have a lot of shortcomings in illumination is used.For example, existing building being overhauled (retrofit) may relate to and make it pass wall or other structures, cable tray or pipeline are installed and/or be made electric wire pass existing pipeline to electric wire wiring to provide wire system.Remain in the planning stage if the building of wire system is installed therein,, just need to provide in the planned design that electric wire includes this building in so if avoid the above-mentioned problem of overhauling.In any situation, to the plan of wired system with install and all need to pay work, this has increased cost.
On the contrary, the selection that wireless system is normally more economical than hard wire Lighting Control Assembly, because significantly reduced the needs of installing and connect electric wire, this is even more important for existing building.Needn't make a plan for lighting control equipment is installed at the during the design of building, maybe must overhaul existing building, the owner of building or operator can be placed on lighting control equipment the place of this equipment of expectation simply.This equipment can be battery powered, or can be connected to outlet simply.In older existed building, the cost savings of wireless system are especially remarkable, otherwise these buildings will need overhauling of complexity and/or trouble.Wireless system still is the preferred selection of domestic. applications, pays attention to cost more because this application is used than commerce usually.
A kind of method that enforcement has the wireless Lighting Control Assembly of wireless lighting control equipment is that these equipment can be communicated with one another by radio frequency (RF) transmission.The Lutron electronics, inc. that an example of this RF system is Coorpersburg PA makes
System.Press
All devices in the agreement, subnet is with identical frequency work, and wherein subnet is single
System.Use single-frequency can avoid and build other interior equipment and disturb, meet the FCC standard, reduce cost etc.Yet the result who does like this is, the equipment in might subnet can be interfering with each other, and this is owing to launch simultaneously by identical frequency and to cause.In addition, in existing RF Lighting Control Assembly, restricted for the number of devices that can on single network, control.The equipment of too many quantity can with the FCC norm conflict because these standards only allow the time of transmission certain-length on characteristic frequency.Present system, for example
Allow 32 equipment of control at most.
In some applications, must use and exceed lighting control equipment that single subnet can be controlled, more.Therefore, may need second subnet to control the equipment of all expectations.Should be realized that, two wireless Lighting Control Assemblies are arranged close to each other, when the both works with identical frequency, can cause serious problem, especially when light scene relates to two subnets.Particularly, might each subnet communicate by letter simultaneously and therefore owing to cause message collision and unnecessarily produce RF and the phase mutual interference.Although owing to use the relatively short RF transmission time in single subnet, the probability that disturbs in a subnet may be less, in the plurality of subnets situation, because the equipment of greater number must receive and transmit the RF transmission, the RF transmission time has increased.
For example, when two incoherent subnet positions were close, each subnet all had the risk of disturbing mutually with another.Yet because each subnet is incoherent, the timing of illumination incident in each subnet (for example scene) will only can take place at one time because of coincidence.On the contrary, when two or more subnets were grouped together on function, the light scene that relates to more than a subnet can make each subnet that works communicate by letter at one time wittingly.As a result, in the plurality of subnets system, for the point that may disturb, the RF transmission time has increased.
Therefore, need a kind of method, be used to increase the number of devices that lighting control networks can be controlled, described lighting control networks uses single RF.Particularly, need a kind of method that links a plurality of subnets, described a plurality of subnets can be as coexisting with the single entity of identical RF work, and carry out the mutual of the overall situation under the situation of data collision each other and communicate by letter not having.More specifically, need a kind of method, control the illumination incident able to programme that relates to a plurality of subnets that starts by central authorities.

Bridge 200 a plurality of independently RF networks of link or the subnets of an embodiment, they move on identical frequency, shown in Fig. 2 B.For example, Fig. 2 B is two exemplary RF lighting control subnet 220 and 230 block diagram according to an embodiment of the invention, they in operation by bridge 200 interconnection.Have master controller 11, lighting control equipment 12, repeater 13 and light fixture 14 although subnet 220 and 230 is shown, should be realized that, as mentioned above, only need comprise individual equipment according to the subnet 220 and 230 of the embodiment of the invention.
As among Fig. 2 B as can be seen, subnet 220 is connected to subnet 230 via wireless connections A and B by bridge 200 in operation.As below in conjunction with what Fig. 3 to 7 discussed, use this bridge 200 to provide this ability: can when bridge 200 sends, on shared RF, not produce message collision near operation as subnet 220 and 230.In other words, when bridge 200 sent, it had eliminated the RF conflict between subnet 220 and 230 by keeping another subnet of not communicating by letter 220 or 230 static with subnet 220 or 230 communication period.In addition, bridge 200 also provides the means that communicate with one another for subnet 220 and 230, and can not make a subnet interrupt the communication of another subnet.Bridge 200 also allows subnet 220 and 230 to operate as the system of independent operating, and the global operation between separate subnet 220 and 230 also is provided simultaneously.
In one embodiment, relate on function that the light scene of relevant subnet 220 and 230 realizes by bridge 200 " imagination " button.The imagination button is the virtual push button that is programmed to have specific function.This imaginary button can pass through for example I/O 225 programmings such as grade.In single or multiple subnets 220 and 230, the specific imaginary button of can programming, to create the illumination scheme of customization, this scheme relates to for example top in conjunction with described lamp 14 light fixture such as grade of Fig. 1.In such embodiment, global operation comprises that standard-sized sheet (ALL ON, all light fixture open), complete shut-down (ALL OFF, all light fixture cut out) and other can relate to the setting able to programme from any amount light fixture of any amount subnet.Recited above a use
Among the embodiment of system, outside standard-sized sheet and complete shut-down, provide 15 kinds of settings able to programme.Although some embodiment (for example below in conjunction with the described embodiment of Fig. 4 to 7) use two subnets, should be realized that, use any amount of subnet all to be consistent with embodiments of the invention equally.Therefore, the imaginary button of bridge 200 can influence the equipment that two systems plant, and can be used in from master controller 11 or by another equipment (for example RS-232 equipment) control subnet 220 and 230.
Single
In the subnet, the user starts light scene by the button of for example pressing the expression light scene on master controller 11.In response, master controller 11 sends the RF signal according to the predetermined set to this light scene to one or more lighting control equipments 12.On the contrary, in one embodiment of the invention, master controller 11 sends the identifier of the selected light scene of expression.Bridge 200 the signal that is received and imaginary button relatively, the light scene of described imaginary button corresponding stored in storer 240 for example.Then, bridge 200 sends to one or more lighting control equipments 12 in one or more subnets 220 and/or 230 with suitable RF signal.Therefore, the master controller 11 in a subnet can be controlled at the lighting control equipment 12 in all- ones subnet 220 and 230.
In another embodiment, bridge 200 can use together with master controller 11, described master controller 11 with existing single subnet
The corresponding to mode of system is moved.For example, in certain embodiments, bridge 200 can add in the subnet 220 and/or 230 that is pre-existing in, and in conjunction with one or more equipment, comprises additional subnet.Should be realized that, when for example existing subnet has reached its capacity and need one or more additional subnet, this situation can occur.As a result, one or more master controllers 11 only can not be configured to response button and press down the transmission scene identifiers.In such embodiments, as below in conjunction with Fig. 3 to 8 discussed, master controller 11 to be sent such as bridge 200 finishes to send, and the imaginary button that sign is corresponding sends suitable RF signal to appropriate illumination opertaing device 12 then.In such embodiments, although order can be sent to some lighting control equipments 12 by twice, once by master controller 11, once by bridge 200, but should be realized that bridge 200 is all same compatible with these master controller of two types, 11 RF host-host protocols.
In an embodiment of the present invention, use
The RF host-host protocol.In this agreement, equipment is attempted avoiding the RF conflict by stand-by period and propagation delay time (backoff).Stand-by period is that the equipment that receives the RF signal is sending the time quantum that should wait for before the signal after this signal ended.Stand-by period is that transmitting apparatus is to the receiving equipment appointment.Propagation delay time also is that the equipment that receives the RF signal is sending the time quantum that should wait for before the signal after this signal ended.But the difference of propagation delay time and stand-by period is propagation delay time by receiving equipment hypothesis, rather than to the receiving equipment appointment.The equipment that receives the RF signal oneself specifies a propagation delay time of waiting for for it when detecting signal after this signal ended, disturb with any other RF signal so that avoid.In case propagation delay time is at the expiration, and if do not have other RF signal to receive, then if desired, this equipment can freely send.In one embodiment, the length of propagation delay time is what to determine at random, thus etc. equipment to be sent unlikely when propagation delay time expires, send the RF signal simultaneously.

Method among top Fig. 3 can be better understood in the embodiment of this method.Although following Fig. 5 to 7 only shows two subnets 220 and 230, can recognize that any amount of subnet 220-230 can be by bridge 200 interconnection in operation.May increase although control the required time of a large amount of subnets, should be realized that, sequential chart only is the purpose that is used for example, and actual sequential chart can have more or less frame and/or functional block, carries out them and realizes desirable order.Therefore, embodiments of the invention provide communications framework, can implement Lighting Control Assembly on this framework.
Forward Fig. 5 now to, show the exemplary sequential chart that is used to overcome the communication protocol of cross-talk situation according to one embodiment of the invention.As what can find out from following Fig. 5 and Fig. 6 to 7, the time advances along the direction of time shaft.As cognoscible, Fig. 5 to 7 does not accurately draw in proportion, because any time, communication protocol or frequency all may influence the definite spacing of these frames.
Only there is the cross-talk situation in each equipment under the situation of mutual communication in a subnet, but another contiguous subnet with same frequency work can cause disturbing or " cross-talk ".Therefore Fig. 5 shows the basic communication incident that is included in device start wherein by 220 pairs of subnets, also has second subnet 230 simultaneously.This sequential chart shows the communication of avoiding cross-talk according to bridge 200.Shown in Figure 53 each bit stream, wherein each has been indicated in communication period subnet 220 that relates to bridge 200 and 230 sequential.
In an embodiment of the present invention, integrating step 307 and the 313 random wait times of discussing specify by starting subnet 220 above.Therefore, in the cross-talk example of Fig. 5, subnet 220 comprises equipment with which, specifies the stand-by period at random for it oneself, simultaneously subnet 230 is specified the maximum random wait time.Equally, each equipment in each subnet 220 and 230 is supposed a propagation delay time at random when receiving the RF signal.Therefore, " worst case " among Fig. 5 is the propagation delay time of hypothesis maximum possible, and " best-case " is the possible propagation delay time of hypothesis minimum.Therefore, as cognoscible, the sequential of " worst case " of subnet 220 as shown by frame 502-518, occurs when the random wait time is the maximum possible value.Should be realized that, below Fig. 6 B, the 6C, 7B and the 7C that are discussed show the sequential of this worst case.
In one embodiment of the invention, four possible random wait and five propagation delay time values are arranged, they can distinguish designated or hypothesis.As cognoscible, any amount of stand-by period and/or propagation delay time value all are consistent with embodiments of the invention equally.In addition, in one embodiment, the value of stand-by period/propagation delay time is that link requires necessary a plurality of time quantum.Link requires (link claim) to measure for example five or 14 half circulations any time.According to an embodiment, when subnet 230 is specified maximum latencies, only need a sequential chart, as by shown in the frame 520-534.As can from Fig. 5 and below Fig. 6 to 7 find out that solid box is represented actual RF transmission, frame of broken lines represents the RF sequential.
When bridge 200 sent, bridge 200 hypothesis propagation delay times were zero, therefore allow bridge 200 can send immediately once finishing in order.As cognoscible, this configuration makes bridge 200 can keep control to subnet 220 and 230, because bridge 200 can at first send after command execution all the time.In case propagation delay time at the expiration,, then can keep free to guarantee RF to the subnet 220 and 230 link requirement that retransfers if there is second order to carry out.Then, this order is retransmitted to request subnet 220 and correspondingly carries out.Therefore, although two subnets 220 and 230 have all received the message that order arrives, have only request subnet 220 actual reception and carry out this order.
Therefore, when subnet 220 receives order, bridge 220 all transmits the link requirement to two subnets 220 and 230, so that " reservation " this work RF.As cognoscible, and as mentioned above, the order that receives from subnet 220 can comprise scene identifiers.As an alternative, this order can comprise the order to equipment in the subnet 220 (for example lighting control equipment 12), so that realize desirable light scene.Initial link to subnet 220 requires by frame 502 and 502 ' expression the link requirement of subnet 230 to be represented by frame 520.Frame 504 and the state of 504 ' expression subnet 220 when requiring wait command according to link.Keep this RF by subnet 220, its communication capacity of subnet 230 temporary suspensions is so that bridge 200 can be communicated by letter under the situation that does not have interference with subnet 220.
The order that frame 506 and 506 ' expression are transmitted by subnet 220, simultaneously at frame 522, subnet 230 continues to wait for.For example, the link that frame 522 expression subnets 230 bases have received at frame 520 requires in wait command, but as cognoscible, this order does not arrive.As a result, subnet 230 keeps static, and this makes bridge 200 can communicate by letter under the situation that does not have message collision to threaten with the equipment in the subnet 220.At frame 508 and 508 ', specify to subnet 220 the random wait time of worst case and best-case respectively, and specify maximum latency to subnet 230 at frame 524.As what discussed, in the present example, are any time amounts less than the maximum possible random wait time for the random wait of the worst case of subnet 220 below in conjunction with Fig. 6 and 7.
In the example communication incident of Fig. 5, order is retransmitted automatically, is correctly received by all devices to guarantee it, thereby at frame 510,510 ' and 526, transmits the second link requirement to subnet 220 and 230 respectively.At frame 512 and 512 ', order is retransmitted to subnet 220, simultaneously at frame 528, and subnet 230 wait command.Should order confirm then, as represented by frame 514 and 514 ' by all devices in the subnet 220.Any method that transmission, reception and collecting device are confirmed all is consistent with embodiments of the invention equally.
As cognoscible, the affirmation correspondence of the worst case of frame 514 for example has the subnet of large number quipments.Described in the above
In the situation of system,, can obtain the longer affirmation time along with near 32 equipment of maximum quantity.Simultaneously, at frame 530, subnet 230 continues to wait for.At frame 516 and 516 ', the exchange bitmap is to guarantee that for example the display 16 of the master controller 11 of subnet 220 upgrades.At frame 532, subnet 230 continues to wait for.Finish part in command sequence, subnet 220 is in frame 518 ' (expression minimum transfer time delay) and duration of waiting for the propagation delay time of its hypothesis at frame 518 (expression maximum transmitted time delay).Equally, at frame 534, subnet 230 is waited for the duration of its propagation delay time.
As cognoscible, and as mentioned above, the function of one embodiment of the invention is during subnet 220 receives and carries out its order, forbids that subnet 230 is with this RF communication.According to this embodiment, subnet 230 must wait for, up to it propagation delay time at the expiration, and this RF is open and available before it can attempt communicating by letter.
Order in succession to same subnet
In certain embodiments, and as mentioned above, bridge 200 can also be zero to keep the control to the RF in a plurality of subnets by the duration of hypothesis propagation delay time.This allows bridge 200 to identical subnet or different subnet transmission orders in succession.For example, when pressing two overall buttons, repeat to transmit a process of commands in order to pass second order.As the situation among Fig. 5, bridge 200 stops non-request subnet (for example subnet 230) to send, and simultaneously these two orders is sent in succession request subnet 220.
Forward Fig. 6 A now to, show according to one embodiment of the invention and be used for realizing the exemplary sequential chart of the communication protocol of order in succession at single subnet.Fig. 6 A shows serial command is sent to processing in the same subnet, and for the purpose of example, this subnet is a subnet 220.Frame 602-612 represents the RF transmission of subnet 220, the RF sequential of frame 614 and 616 expression subnets 220, the RF transmission of frame 618 and 620 expression subnets 230, the RF sequential of frame 622 and 624 expression subnets 230.
