The appliance 2 is already lit. It is assumed that in this state, some of the lighting fixtures 2 of the lighting fixtures 2 are switched to the extinguished state due to the operation of the wireless switch 6. At this time, when receiving the state notification signal for notifying the state change from the transmission unit 4, the control circuit 33 switches the LED 32 to a display state in which the display fixture 2 has been turned off. Thereby, the control circuit 33 notifies the user of the state in which all the lighting fixtures 2 to be lit are not lit.
傳送單元4具有:可與集中開關3以及接收器5以輪詢方式通信的有線通信電路41;使用有線通信電路41與集中開關3以及接收器5通信的控制電路42;以及記憶體43。控制電路42,當從集中開關3接收到操作信號時,便根據該操作信號掌握作為控制對象的照明器具2的位址以及控制內容。控制電路42,例如,對所掌握的每個位址(各個照明器具2),將該位址當作發送目的地,產生表示對於該位址的照明器具2的控制內容的照明控制信號。控制電路42,將該等照明控制信號連續發送到接收器5。控制電路42,當從接收器5接收到狀態通知信號時,根據該狀態通知信號掌握各照明器具2的狀態,將表示該狀態的資訊信號儲存於記憶體43,並且發送到顯示器。The transmission unit 4 has a wired communication circuit 41 that can communicate with the centralized switch 3 and the receiver 5 in a polling manner, a control circuit 42 that communicates with the centralized switch 3 and the receiver 5 using the wired communication circuit 41, and a memory 43. When receiving the operation signal from the centralized switch 3, the control circuit 42 grasps the address and the control content of the lighting fixture 2 to be controlled based on the operation signal. The control circuit 42 generates, for example, a lighting control signal indicating the control content of the lighting fixture 2 for the address for each address (each lighting fixture 2) that is grasped as the transmission destination. The control circuit 42 continuously transmits the illumination control signals to the receiver 5. When receiving the state notification signal from the receiver 5, the control circuit 42 grasps the state of each lighting fixture 2 based on the state notification signal, stores the information signal indicating the state in the memory 43, and transmits it to the display.
接收器5具有:與傳送單元4通信的有線通信電路51;與無線開關6通信的無線通信電路52;使用有線通信電路51以及無線通信電路52中介傳送傳送單元4以及無線開關6之間的信號的控制電路53;以及記憶體54。控制電路53,在從傳送單元4接收的照明控制信號之中,將對其配置下的照明器具2的照明控制信號抽出,依序累積儲存於記憶體54。所謂控制電路53的配置下的照明器具2,係指作為控制電路53的通信對象的無線開關6所控制的照明器具2。控制電路53,在應將照明控制信號發送到無線開關6的時序到來時,從記憶體54讀取照明控制信號,對配置下的無線開關6發送照明控制信號。控制電路53,當接收到來自無線開關6的狀態通知信號時,便將該狀態通知信號發送到傳送單元4。The receiver 5 has: a wired communication circuit 51 in communication with the transmitting unit 4; a wireless communication circuit 52 in communication with the wireless switch 6; and a signal between the transmitting unit 4 and the wireless switch 6 is intermediated using the wired communication circuit 51 and the wireless communication circuit 52 Control circuit 53; and memory 54. The control circuit 53 extracts the illumination control signals of the lighting fixtures 2 disposed therein from among the illumination control signals received from the transmission unit 4, and sequentially stores them in the memory 54 in order. The lighting fixture 2 in the arrangement of the control circuit 53 is the lighting fixture 2 controlled by the wireless switch 6 as the communication target of the control circuit 53. The control circuit 53 reads the illumination control signal from the memory 54 when the timing at which the illumination control signal should be transmitted to the wireless switch 6, and transmits the illumination control signal to the wireless switch 6 under the arrangement. The control circuit 53 transmits the status notification signal to the transmitting unit 4 when receiving the status notification signal from the wireless switch 6.
無線開關6具有:可與接收器5以無線通信的無線通信電路61;使交流電源對照明器具2的供電導通或切斷的繼電器62;用來實行操作以切換照明器具2之狀態的操作按鈕63;控制電路64;以及記憶體65。繼電器62,插入從交流電源向照明器具2的供電線之中,切換該供電線的導通狀態與非導通狀態,藉此使供應到照明器具2的供電導通或切斷,以切換照明器具2的狀態。控制電路64用無線通信電路61與接收器5通信。控制電路64,當從接收器5接收到照明控制信號時,便根據該照明控制信號以及使用者對操作按鈕63的操作控制繼電器62對供電的導通或切斷。控制電路64,在使用者對操 作按鈕63的操作切換了照明器具2的狀態時,將狀態通知信號發送到接收器5。記憶體65,係將狀態通知信號暫時儲存用的記憶體。對記憶體65寫入狀態通知信號以及從記憶體65讀取狀態通知信號,係被控制電路64所控制。The wireless switch 6 has a wireless communication circuit 61 that can communicate wirelessly with the receiver 5, a relay 62 that turns on or off the power supply of the illuminating device 2 by the AC power source, and an operation button for performing an operation to switch the state of the luminaire 2 63; control circuit 64; and memory 65. The relay 62 is inserted into the power supply line from the AC power source to the lighting fixture 2, and switches the conduction state and the non-conduction state of the power supply line, thereby turning on or off the power supplied to the lighting fixture 2 to switch the lighting fixture 2 status. The control circuit 64 communicates with the receiver 5 using the wireless communication circuit 61. The control circuit 64, when receiving the illumination control signal from the receiver 5, controls the conduction or disconnection of the power supply to the relay 62 based on the illumination control signal and the operation of the operation button 63 by the user. Control circuit 64, in the user's operation When the operation of the button 63 is switched to the state of the lighting fixture 2, a state notification signal is transmitted to the receiver 5. The memory 65 is a memory for temporarily storing the status notification signal. The state notification signal is written to the memory 65 and the state notification signal is read from the memory 65, and is controlled by the control circuit 64.
以下,針對控制電路33、42、53、64的動作,為了方便說明,分別以集中開關3、傳送單元4、接收器5以及無線開關6為動作主體進行說明。Hereinafter, the operation of the control circuits 33, 42, 53, and 64 will be described with the focus switch 3, the transfer unit 4, the receiver 5, and the wireless switch 6 as the main body of the operation for convenience of explanation.
圖3係表示在傳送單元4的總括控制期間傳送單元4以及接收器5(例如接收器5A~5J)各自的動作。首先,說明傳送單元4的動作。在此,假設使用者使用集中開關3進行總括切換照明器具2之狀態的操作。此時,傳送單元4,將表示照明器具2的總括控制期間t1的開始時序的開始通知信號S1、照明控制信號S2、通知該照明控制信號S2的發送結束的虛擬等待(dummy wait)信號S3以該順序發送到接收器5。之後,傳送單元4,將表示總括控制期間t1的結束時序的結束通知信號S4發送到接收器5。照明控制信號S2的發送期間t2包含於總括控制期間t1之中。FIG. 3 shows the respective operations of the transmitting unit 4 and the receiver 5 (for example, the receivers 5A to 5J) during the collective control of the transmitting unit 4. First, the operation of the transfer unit 4 will be described. Here, it is assumed that the user uses the centralized switch 3 to collectively switch the state of the lighting fixture 2. At this time, the transfer unit 4 sets a start notification signal S1 indicating the start timing of the collective control period t1 of the lighting fixture 2, the illumination control signal S2, and a dummy wait signal S3 indicating that the transmission of the illumination control signal S2 is completed. This sequence is sent to the receiver 5. Thereafter, the transmitting unit 4 transmits an end notification signal S4 indicating the end timing of the collective control period t1 to the receiver 5. The transmission period t2 of the illumination control signal S2 is included in the collective control period t1.
在說明接收器5的動作之前,先說明接收器5以及無線開關6(參照上述圖1)之間的通信方式。該通信方式,係所謂時槽式隨機取用方式,接收器5以及無線開關6,根據接收器5所定期無線發送的信標信號B1指定時槽T1,與該指定的時槽T1同步,進行無線通信。接收器5彼此之間利用有線通信同步。例如,預先設定成基準器的接收器5A,將同步信號發送到其他的接收器,接收器5根據該同步信號,在彼此之間,使信標信號B1的發送時序同步,並使時槽T1的時序大略一致。各接收器5,以彼此相異的時槽T1發送信標信號B1。在發送時,各接收器5,執行載波感測,當檢測到其他接收器5的信號發送時,便中止信標信號B1的發送。信標信號B1,由於係定期發送,故即使是若干次中止發送,也幾乎不會影響到通信精度。Before explaining the operation of the receiver 5, the communication method between the receiver 5 and the wireless switch 6 (refer to FIG. 1 described above) will be described. The communication method is a so-called time slot type random access method, and the receiver 5 and the wireless switch 6 specify the time slot T1 based on the beacon signal B1 periodically transmitted by the receiver 5 in synchronization with the designated time slot T1. Wireless communication. The receivers 5 are synchronized with each other using wired communication. For example, the receiver 5A set in advance as a reference transmits a synchronization signal to another receiver, and the receiver 5 synchronizes the transmission timing of the beacon signal B1 with each other based on the synchronization signal, and makes the time slot T1 The timing is roughly the same. Each of the receivers 5 transmits the beacon signal B1 in time slots T1 different from each other. At the time of transmission, each receiver 5 performs carrier sensing, and when the signal transmission of the other receiver 5 is detected, the transmission of the beacon signal B1 is suspended. Since the beacon signal B1 is periodically transmitted, even if the transmission is suspended several times, the communication accuracy is hardly affected.
接著,除了上述圖3之外,更參照圖4說明傳送單元4發送上述各信號而接收器5接收到該等信號時的接收器5的動作。各接收器5,在從傳送單元4接收到開始通知信號S1時(在# 101為Yes),根據該開始通知信號S1檢測到 總括控制期間t1的開始(#102)。之後,各接收器5,在各自從傳送單元4接收到照明控制信號S2時(在#103為Yes),將該照明控制信號S2之中的對各接收器5的配置下的照明器具2的照明控制信號S2抽出並儲存(#104)。所謂各接收器5的配置下的照明器具2,係指作為各接收器5的通信對象的無線開關6所控制的照明器具2。在以下的說明中,將傳送單元4所發送的照明控制信號記載為「S2」,將各接收器5從該照明控制信號S2之中抽出並儲存的照明控制信號記載為「s2」,以茲區別。各接收器5,在照明控制信號S2的接收期間,將照明控制信號s2依序累積儲存。Next, in addition to the above-described FIG. 3, the operation of the receiver 5 when the transmission unit 4 transmits the above-described respective signals and the receiver 5 receives the signals will be described with reference to FIG. Each receiver 5, upon receiving the start notification signal S1 from the transmission unit 4 (Yes at #101), detects based on the start notification signal S1. The general control period begins with the start of time t1 (#102). Thereafter, each receiver 5 receives the illumination control signal S2 from the transmission unit 4 (Yes at #103), and illuminates the lighting fixture 2 in the arrangement of the respective receivers 5 among the illumination control signals S2. The illumination control signal S2 is extracted and stored (#104). The lighting fixture 2 in the arrangement of the respective receivers 5 refers to the lighting fixture 2 controlled by the wireless switch 6 that is the communication target of each receiver 5. In the following description, the illumination control signal transmitted by the transmission unit 4 is described as "S2", and the illumination control signal extracted and stored by each receiver 5 from the illumination control signal S2 is described as "s2". the difference. Each of the receivers 5 sequentially accumulates the illumination control signal s2 during the reception of the illumination control signal S2.
各接收器5,在以各接收器5均不同的方式預先分配好的分配時槽T2,將所儲存的照明控制信號s2無線發送到無線開關6。當在照明控制信號S2的接收期間分配時槽T2來臨時(在#105為Yes),各接收器5將到該時點為止所累積的照明控制信號s2發送到無線開關6(#106)。Each of the receivers 5 transmits the stored illumination control signal s2 to the wireless switch 6 wirelessly in a predetermined distribution time slot T2 in a manner different from each of the receivers 5. When the slot T2 is temporarily allocated during the reception of the illumination control signal S2 (Yes at #105), each receiver 5 transmits the illumination control signal s2 accumulated up to that point in time to the wireless switch 6 (#106).
在此,各接收器5,在完成來自傳送單元4的照明控制信號S2的接收之後,便從傳送單元4接收虛擬等待信號S3(在#107為Yes)。此時,從該接收之後到總括控制期間t1的結束時序,各接收器5,重複對以無線開關6進行照明控制信號s2的發送,發送照明控制信號s2既定的次數(例如2次)(#108)。Here, each receiver 5 receives the virtual waiting signal S3 from the transmitting unit 4 after receiving the illumination control signal S2 from the transmitting unit 4 (Yes at #107). At this time, from the end of the reception to the end timing of the collective control period t1, each receiver 5 repeats the transmission of the illumination control signal s2 by the wireless switch 6, and transmits the illumination control signal s2 a predetermined number of times (for example, twice) (#) 108).
各接收器5,在從傳送單元4接收到結束通知信號S4時(在#109為Yes),便根據該結束通知信號S4檢測出總括控制期間t1的結束(#110)。總括控制期間t1結束之後,各接收器5解除僅在分配時槽T2發送信號這個限制。各接收器5,在總括控制期間t1以外的期間從傳送單元4接收到欲送到無線開關6的信號時,便將該信號在任意的時槽T1發送到無線開關6。When receiving the end notification signal S4 from the transmission unit 4 (Yes in #109), each receiver 5 detects the end of the collective control period t1 based on the end notification signal S4 (#110). After the end of the collective control period t1, each receiver 5 releases the restriction that the signal is transmitted only in the slot T2 at the time of allocation. Each receiver 5 receives a signal to be sent to the wireless switch 6 from the transmission unit 4 during a period other than the collective control period t1, and transmits the signal to the wireless switch 6 in an arbitrary time slot T1.
圖5係表示在總括控制期間t1接收器5與無線開關6之間的信號相撞之防止處理。當總括控制期間t1開始時(在#201為Yes),各接收器5,對無線開關6,發送指示上述狀態通知信號發送停止的停止指示信號S5(#202)。該停止指示信號S5,可包含於在總括控制期間t1的最初送到以無線開關6進行 照明控制信號s2中,亦可有別於該照明控制信號s2另外發送。各無線開關6,在從接收器5接收到停止指示信號S5時,檢測到總括控制期間t1的開始,並停止狀態通知信號的發送(#301)。各無線開關6,當在該停止期間照明器具2的狀態發生變化時,將狀態通知信號儲存並保持。Fig. 5 shows a process of preventing collision of signals between the receiver 5 and the wireless switch 6 during the collective control period t1. When the collective control period t1 is started (Yes in #201), each receiver 5 transmits a stop instruction signal S5 (#202) indicating that the state notification signal transmission is stopped to the wireless switch 6. The stop indication signal S5 may be included in the initial transmission during the collective control period t1 to be performed by the wireless switch 6. The illumination control signal s2 may be additionally transmitted separately from the illumination control signal s2. When receiving the stop instruction signal S5 from the receiver 5, each of the wireless switches 6 detects the start of the collective control period t1 and stops the transmission of the state notification signal (#301). Each of the wireless switches 6 stores and holds the status notification signal when the state of the lighting fixture 2 changes during the stop.
當總括控制期間t1結束時(在#203為Yes),各接收器5,對無線開關6發送指示狀態通知信號的發送停止解除的解除指示信號S6(#204)。各無線開關6,根據解除指示信號S6檢測到總括控制期間t1的結束,將狀態通知信號的發送停止解除(#302)。When the collective control period t1 ends (Yes in #203), each receiver 5 transmits a release instruction signal S6 (#204) indicating that the transmission of the status notification signal is released to the wireless switch 6. Each of the wireless switches 6 detects the end of the collective control period t1 based on the release instruction signal S6, and stops the transmission of the state notification signal (#302).
各無線開關6,在狀態通知信號的發送停止解除之後,隨機選擇發送到此為止所保持之狀態通知信號的時槽T1(#303),在所選擇的時槽T1發送狀態通知信號S7(#304)。各接收器5,接收從無線開關6所發送的狀態通知信號S7,將該狀態通知信號S7轉送到傳送單元4(#205)。After the transmission of the state notification signal is stopped, each of the wireless switches 6 randomly selects the time slot T1 (#303) for transmitting the state notification signal held until then, and transmits the state notification signal S7 (#) in the selected time slot T1. 304). Each receiver 5 receives the status notification signal S7 transmitted from the wireless switch 6, and transfers the status notification signal S7 to the transmission unit 4 (#205).
圖6係表示照明控制信號s2的資料部D1的構成。該資料部D1,係由與被接收器5設定為通信對象的無線開關6的數目對應的位元數的位元列B2所構成,對作為通信對象的無線開關6多重傳播。位元列B2,在預先設定好數目的位元B3的毎一個,顯示與該位元B3對應的無線開關6對照明器具2的控制內容。在本實施態樣中,位元列B2的位元數,設定為與作為接收器5的通信對象的無線開關6的數目相同,一個位元B3與一台無線開關6對應,各位元B3,例如,以「1」表示「點亮」,以「0」表示「熄滅」,作為控制內容。該等對應關係亦可相反。Fig. 6 shows the configuration of the data portion D1 of the illumination control signal s2. The data unit D1 is composed of a bit column B2 of the number of bits corresponding to the number of wireless switches 6 to be set by the receiver 5, and is multiplexed with the wireless switch 6 as a communication target. The bit column B2 is set to a predetermined number of bits B3 in advance, and the content of control of the lighting fixture 2 by the wireless switch 6 corresponding to the bit B3 is displayed. In the present embodiment, the number of bits of the bit column B2 is set to be the same as the number of the wireless switches 6 that are the communication targets of the receiver 5, and one bit B3 corresponds to one wireless switch 6, and the bit B3, For example, "1" indicates "lighting" and "0" indicates "off" as control content. These correspondences can also be reversed.
藉由該等照明控制信號s2的產生,各接收器5,各自將在從傳送單元4所接收到的照明控制信號S2之中,以各接收器5的配置下的複數台照明器具2為發送目的地的複數個照明控制信號S2,集中作為一個照明控制信號s2。各接收器5,當在從傳送單元4所接收到的照明控制信號S2之中,並未包含對各接收器5的配置下的任一個照明器具2的照明控制信號S2時,便各自將對該照明器具2的控制內容設定為例如「熄滅」。By the generation of the illumination control signals s2, each of the receivers 5 transmits each of the illumination control signals S2 received from the transmission unit 4 by the plurality of illumination fixtures 2 in the arrangement of the respective receivers 5. A plurality of illumination control signals S2 of the destination are concentrated as one illumination control signal s2. Each of the receivers 5, when the illumination control signal S2 received from the transmission unit 4 does not include the illumination control signal S2 for any of the illumination devices 2 in the arrangement of the respective receivers 5, will each be paired The control content of the lighting fixture 2 is set to, for example, "extinguished".
各無線開關6,各自預先掌握在從接收器5所接收到的照明控制信號s2的資料部D1之中應被識別為對各無線開關6的指示的控制內容所對應的位元B3的順序。各無線開關6,於照明器具2執行該順序之位元B3所表示之內容的控制。Each of the wireless switches 6 preliminarily grasps the order of the bit B3 corresponding to the control content that should be recognized as an instruction to each wireless switch 6 among the data portions D1 of the illumination control signal s2 received from the receiver 5. Each of the wireless switches 6 performs control of the content indicated by the bit B3 of the sequence in the lighting fixture 2.
在本實施態樣中,如上述圖3所示的,由於各接收器5在不同的分配時槽T2將照明控制信號s2發送到無線開關6,故可防止照明控制信號s2的發送時序重疊。因此,可防止各照明控制信號s2之間的撞在一起,藉此,便可將照明控制信號s2確實地送到無線開關6。結果,可使以無線開關6進行照明控制的可靠度提高。In the present embodiment, as shown in FIG. 3 described above, since the respective receivers 5 transmit the illumination control signal s2 to the wireless switch 6 at different allocation time slots T2, it is possible to prevent the transmission timing of the illumination control signal s2 from overlapping. Therefore, collision between the respective illumination control signals s2 can be prevented, whereby the illumination control signal s2 can be surely sent to the wireless switch 6. As a result, the reliability of the illumination control by the wireless switch 6 can be improved.
另外,當接收器5對無線開關6發送信號時,在總括控制期間t1中,信號的發送雖被限定在分配時槽T2,然而在此以外的期間,可於任意的時槽T1發送信號,故信號的傳送遲延情況變少。因此,可達到提高通信速度之目的。Further, when the receiver 5 transmits a signal to the wireless switch 6, the signal transmission is limited to the allocation time slot T2 in the collective control period t1, but the signal can be transmitted in any time slot T1 during the other periods. Therefore, the transmission delay of the signal is less. Therefore, the purpose of improving the communication speed can be achieved.
另外,接收器5,在從傳送單元4接收照明控制信號S2的期間,在分配時槽T2到來複數次的情況下,在各時點將所累積的照明控制信號s2在每個分配時槽T2轉送到無線開關6。藉此,越早從傳送單元4接收的照明控制信號S2,會被轉送到無線開關6越多次。因此,可使無線通信的可靠度提高。另外,接收器5,由於在來自傳送單元4的照明控制信號S2的接收完成之後,對無線開關6重複發送照明控制信號s2,故可更進一步提高無線通信的可靠度。Further, while receiving the illumination control signal S2 from the transmission unit 4, the receiver 5 transfers the accumulated illumination control signal s2 at each time slot T2 at each time point when the allocation time slot T2 is repeated a plurality of times. Go to the wireless switch 6. Thereby, the earlier the illumination control signal S2 received from the transmission unit 4 is transferred to the wireless switch 6 more times. Therefore, the reliability of wireless communication can be improved. Further, since the receiver 5 repeatedly transmits the illumination control signal s2 to the wireless switch 6 after the reception of the illumination control signal S2 from the transmission unit 4 is completed, the reliability of the wireless communication can be further improved.
另外,當設定了複數台無線開關6作為接收器5的通信對象時,藉由從接收器5到複數台以無線開關6進行照明控制信號s2的多重傳播,便可在一個分配時槽T2發送照明控制信號s2。藉此,比起對每個無線開關6發送照明控制信號s2的情況而言,更可減少照明控制信號s2的發送次數。因此,可縮短總括控制所需要的時間。Further, when a plurality of wireless switches 6 are set as the communication targets of the receiver 5, by performing multiple propagation of the illumination control signal s2 from the receiver 5 to the plurality of wireless switches 6, the transmission can be performed in one allocation time slot T2. Lighting control signal s2. Thereby, the number of transmissions of the illumination control signal s2 can be further reduced as compared with the case where the illumination control signal s2 is transmitted to each of the wireless switches 6. Therefore, the time required for the collective control can be shortened.
另外,在總括控制期間t1中,由於無線開關6的狀態通知信號S7的發送被禁止,故可防止該狀態通知信號S7與接收器5所發送之照明控制信號s2撞在一起。藉此,便可提高無線通信的可靠度。另外,由於在總括控制期間t1結束時,接收器5會對無線開關6發送解除指示信號S6,故無線開關6可根據解除指示信號S6迅速地識別到狀態通知信號S7的發送停止被解除。如是,在此之後,當照明器具2的狀態發生變化時,便可將狀態通知信號S7很快地發送到接收器5,並經由接收器5在初期便對傳送單元4通知照明器具2的狀態變化。Further, in the collective control period t1, since the transmission of the state notification signal S7 of the wireless switch 6 is prohibited, the state notification signal S7 can be prevented from colliding with the illumination control signal s2 transmitted from the receiver 5. Thereby, the reliability of wireless communication can be improved. Further, since the receiver 5 transmits the release instruction signal S6 to the wireless switch 6 when the collective control period t1 is completed, the wireless switch 6 can promptly recognize that the transmission stop of the state notification signal S7 is released based on the release instruction signal S6. If so, after the state of the lighting fixture 2 changes, the state notification signal S7 can be quickly transmitted to the receiver 5, and the state of the lighting fixture 2 is notified to the transmitting unit 4 via the receiver 5 at an early stage. Variety.
另外,即使在總括控制期間t1照明器具2的狀態發生變化,在總括控制期間t1結束之後,仍可使傳送單元4掌握該變化。藉此,傳送單元4的各照明器具2的現狀掌握正確性會提升。而且,為了提升該正確性,在總括控制期間t1結束之後所實施的無線開關6的狀態通知信號S7的發送,係在隨機選擇的時槽T1。因此,可防止各狀態通知信號S7之間發生相撞。In addition, even if the state of the lighting fixture 2 changes during the collective control period t1, the transfer unit 4 can be made to grasp the change after the end of the collective control period t1. Thereby, the correctness of the current situation of each lighting fixture 2 of the transport unit 4 is improved. Further, in order to improve the accuracy, the transmission of the state notification signal S7 of the wireless switch 6 implemented after the end of the collective control period t1 is in the randomly selected time slot T1. Therefore, collision between the respective state notification signals S7 can be prevented.
另外,例如,當在建物內已經設置了切換照明器具2之狀態的開關時,只要將該開關更換成無線開關6,並設置集中開關3、傳送單元4以及接收器5,便可導入負載控制系統1。另外,由於不需要在無線開關6與接收器5之間設置配線,故施工作業比較簡單,而且該等構件的設置自由度變高。Further, for example, when a switch for switching the state of the lighting fixture 2 has been set in the construction, the load can be introduced by replacing the switch with the wireless switch 6, and providing the centralized switch 3, the transmission unit 4, and the receiver 5. System 1. Further, since it is not necessary to provide wiring between the wireless switch 6 and the receiver 5, the construction work is relatively simple, and the degree of freedom in setting the members becomes high.
以下,參照圖式說明上述實施態樣的各變化實施例的負載控制系統1。與上述實施態樣相同的構成要件,會附上相同的符號。另外,僅針對與上述實施態樣相異之點進行說明。各變化實施例之負載控制系統1,用以防止在總括控制期間t1的信號相撞的構造,與上述實施態樣不同。Hereinafter, the load control system 1 of each of the modified embodiments of the above-described embodiments will be described with reference to the drawings. The same constituent elements as those of the above embodiment will be denoted by the same reference numerals. In addition, only the point different from the above embodiment will be described. The load control system 1 of each of the modified embodiments is different from the above-described embodiment in the configuration for preventing the signals from colliding during the collective control period t1.
(第1變化實施例)(First variation embodiment)
圖7係表示在第1變化實施例之負載控制系統1中無線開關6的信號相撞之防止處理。在本變化實施例中,當總括控制期間t1開始時,無線開關6便自動地將發送停止。Fig. 7 is a view showing the process of preventing the collision of the signals of the wireless switch 6 in the load control system 1 of the first modified embodiment. In the present modified embodiment, when the collective control period t1 is started, the wireless switch 6 automatically stops the transmission.
無線開關6,在從接收器5接收到照明控制信號s2時(在#401為Yes),判斷該照明控制信號s2是否為多重傳播的照明控制信號s2。該判斷方法,係判斷照明控制信號S2的發送目的地位址是否為複數,當判斷位址為複數時,便判斷照明控制信號s2為多重傳播信號。當判斷照明控制信號s2為多重傳播的照明控制信號s2時(在#402為Yes),無線開關6,便識別出總括控制期間t1的開始,並將狀態通知信號S7的發送停止(#403)。The wireless switch 6 determines whether the illumination control signal s2 is the multi-propagation illumination control signal s2 when the illumination control signal s2 is received from the receiver 5 (Yes in #401). The determination method determines whether the transmission destination address of the illumination control signal S2 is a complex number, and when the determination address is a complex number, determines that the illumination control signal s2 is a multiple propagation signal. When it is judged that the illumination control signal s2 is the multi-propagation illumination control signal s2 (Yes at #402), the wireless switch 6 recognizes the start of the collective control period t1 and stops the transmission of the status notification signal S7 (#403) .
在本變化實施例中,與上述實施態樣同樣可防止照明控制信號s2與狀態通知信號S7撞在一起。另外,不像上述實施態樣那樣為了防止該相撞而從接收器5對無線開關6發送停止指示信號S5,亦無不可。藉此,可使接收器5的構造簡單化、防止無線通信的擁塞以及縮短總括控制所花費的時間。In the present modified embodiment, as in the above-described embodiment, the illumination control signal s2 can be prevented from colliding with the state notification signal S7. Further, unlike the above-described embodiment, it is not necessary to transmit the stop instruction signal S5 from the receiver 5 to the wireless switch 6 in order to prevent the collision. Thereby, the configuration of the receiver 5 can be simplified, the congestion of wireless communication can be prevented, and the time taken for the collective control can be shortened.
(第2變化實施例)(Second variant embodiment)
圖8係表示第2變化實施例之負載控制系統1的無線開關6的信號相撞之防止處理。在本變化實施例中,無線開關6,在欲發送狀態通知信號S7時,在從時槽T1的前頭開始算起經過比時槽T1更短的既定時間之後(在#501為Yes),實行載波感測(#502)。當在載波感測中未檢測到其他無線開關6或是接收器5的信號發送時(在#503為Yes),無線開關6便對接收器5發送狀態通知信號S7(#504)。Fig. 8 is a view showing a process of preventing collision of a signal of the wireless switch 6 of the load control system 1 of the second modified embodiment. In the present modified embodiment, when the state notification signal S7 is to be transmitted, the wireless switch 6 is executed after a predetermined time shorter than the time slot T1 from the beginning of the time slot T1 (Yes at #501). Carrier sensing (#502). When the signal transmission of the other wireless switch 6 or the receiver 5 is not detected in the carrier sensing (Yes at #503), the wireless switch 6 transmits a status notification signal S7 to the receiver 5 (#504).
在本變化實施例中,由於在無線開關6欲發送狀態通知信號S7時,若接收器5發送照明控制信號s2,則狀態通知信號S7不會發送,故可避免照明控制信號s2與狀態通知信號S7撞在一起。而且,不像上述實施態樣那樣為了避免該相撞而從接收器5對無線開關6發送停止指示信號S5,亦無不可。另外,不像上述實施態樣那樣為了對無線開關6通知已可發送狀態通知信號S7而從接收器5對無線開關6發送解除指示信號S6,亦無不可。藉此,可使接收器5的構造更加簡單化。In the present variation, since the state notification signal S7 is not transmitted when the wireless switch 6 is to transmit the state notification signal S7, if the receiver 5 transmits the illumination control signal s2, the illumination control signal s2 and the state notification signal can be avoided. S7 hits together. Further, unlike the above-described embodiment, it is not necessary to transmit the stop instruction signal S5 from the receiver 5 to the wireless switch 6 in order to avoid the collision. Further, unlike the above-described embodiment, it is not necessary to transmit the release instruction signal S6 from the receiver 5 to the wireless switch 6 in order to notify the wireless switch 6 of the transmittable state notification signal S7. Thereby, the configuration of the receiver 5 can be made simpler.
(第3變化實施例)(Third variation embodiment)
在第3變化實施例之負載控制系統1中,在接收器5完成來自傳送單元4的照明控制信號S2的接收之後,到總括控制期間t1的結束時序為止,對無線開關6重複發送的照明控制信號s2具備特徴。表示照明控制信號s2的剩餘發送次數的剩餘次數通知信號由接收器5附加於該照明控制信號S2。In the load control system 1 of the third modified embodiment, after the receiver 5 completes the reception of the illumination control signal S2 from the transmission unit 4, the illumination control for repeatedly transmitting the wireless switch 6 until the end timing of the collective control period t1 Signal s2 has characteristics. A remaining number notification signal indicating the number of remaining transmissions of the illumination control signal s2 is added to the illumination control signal S2 by the receiver 5.
圖9係表示使用該照明控制信號s2的無線開關6的信號相撞之防止處理。無線開關6,與上述實施態樣同樣根據來自傳送單元4的停止指示信號S5,或是與上述第1變化實施例同樣根據照明控制信號s2,將狀態通知信號S7的發送停止(#601)。無線開關6,判斷剩餘次數通知信號所示之發送次數是否為零,當判斷發送次數為零時(#602),將狀態通知信號S7的發送停止解除(#603)。Fig. 9 shows a signal collision preventing process of the wireless switch 6 using the illumination control signal s2. Similarly to the above-described embodiment, the wireless switch 6 stops the transmission of the state notification signal S7 based on the stop instruction signal S5 from the transmission unit 4 or the illumination control signal s2 as in the first variation embodiment (#601). The wireless switch 6 determines whether or not the number of transmissions indicated by the remaining number notification signal is zero. When it is determined that the number of transmissions is zero (#602), the transmission of the status notification signal S7 is stopped (#603).
在本變化實施例中,無線開關6,可在接收器5所通知的照明控制信號s2的剩餘發送次數為0時,預測總括控制期間t1已經結束,並使狀態通知信號S7的發送再度開始。藉此,無須像上述實施態樣那樣為了通知總括控制期間t1的結束而從接收器5對無線開關6發送解除指示信號S6。因此,可使接收器5的構造更加簡單化。In the present modified embodiment, the wireless switch 6 can predict that the collective control period t1 has ended when the remaining number of transmissions of the illumination control signal s2 notified by the receiver 5 is 0, and the transmission of the status notification signal S7 is resumed. Thereby, it is not necessary to transmit the release instruction signal S6 from the receiver 5 to the wireless switch 6 in order to notify the end of the collective control period t1 as in the above-described embodiment. Therefore, the configuration of the receiver 5 can be made simpler.
另外,本發明不限於上述的實施態樣以及各變化實施例的構造,可因應使用目的作出各種變化。例如,亦可在上述各變化實施例之中,將任一變化實施例的構造,與其他的變化實施例的構造組合。另外,負載不限於照明器具2,亦可為其他電氣裝置。另外,無線開關6,亦可在狀態通知信號S7的發送停止解除之後,將到此為止所保持的狀態通知信號S7,在預先以不重複的方式分配的時槽T1發送。此時,無須像上述實施態樣那樣為了隨機選擇發送狀態通知信號S7的時槽T1而使無線開關6儲存複雜的程式等。藉此,可使無線開關6的構造簡單化。另外,各接收器5,亦可在發送到無線開關6的位元列B2,以2位元表現「點亮」、「熄滅」以及「無變化」這3個狀態,作為無線開關6的照明器具2的控制內容。此時,位元列B2以例如每2個位元表示與該等位元對應的無線開關6的控制內容。Further, the present invention is not limited to the above-described embodiments and the configurations of the respective modified embodiments, and various changes can be made depending on the purpose of use. For example, the configuration of any of the modified embodiments may be combined with the configuration of other modified embodiments among the above-described various modified embodiments. Further, the load is not limited to the lighting fixture 2, and may be other electrical devices. Further, after the transmission of the state notification signal S7 is stopped, the wireless switch 6 may transmit the state notification signal S7 held so far in the time slot T1 that is allocated in advance without being repeated. At this time, the wireless switch 6 does not need to store a complicated program or the like in order to randomly select the time slot T1 of the transmission state notification signal S7 as in the above-described embodiment. Thereby, the structure of the wireless switch 6 can be simplified. In addition, each of the receivers 5 can also express the three states of "lighting", "extinguishing", and "no change" in the bit row B2 transmitted to the wireless switch 6 as the illumination of the wireless switch 6. The control content of the appliance 2. At this time, the bit column B2 indicates the control content of the wireless switch 6 corresponding to the bits, for example, every two bits.
