Description
本發明係有關一種熱射線式無線發射器，其回應於對從人體輻射出之熱射線的感測，發射控制信號，用以控制在樓梯和走廊等人們來往的地方所安裝的照明器材；且本發明係有關一種無線接收器，其接收從無線發射器所發射出的無線電信號並控制照明器材。The present invention relates to a heat ray type wireless transmitter that emits a control signal for controlling lighting equipment installed in places where people are coming and going, such as stairs and corridors, in response to sensing of heat rays radiated from a human body; The present invention relates to a wireless receiver that receives radio signals transmitted from a wireless transmitter and controls lighting fixtures.
在此之前，存在有照明設備，其感測出現在感測區域中的人們，並且從發射器發射出諸如從那裡所獲得到的感測信號之控制信號，經由預定(有線)的通信線路而到照明器材，藉以控制該照明器材。此類之照明設備的優點在於其通信可靠性非常地高，因而能夠確切地發射控制信號。但是，這種照明設備存在的問題是，需要進行用以經由該通信線路而將所有的發射器和所有的照明器材彼此互相連接的構建工程，因而花費了極度大量的時間和人力。Prior to this, there was a lighting device that senses people appearing in the sensing area and emits a control signal from the transmitter, such as a sensing signal obtained therefrom, via a predetermined (wired) communication line. To the lighting equipment, to control the lighting equipment. An advantage of such a lighting device is that its communication reliability is very high and thus it is possible to transmit a control signal exactly. However, such a lighting device has a problem in that a construction work for interconnecting all the transmitters and all the lighting fixtures to each other via the communication line is required, thus taking an extremely large amount of time and labor.
為了解決上述問題，已經提出了一種照明設備，其使用紅外線等等，藉由簡單的無線電通信(無線通信)，從 發射器發射出控制信號至照明器材，藉以控制照明器材。這種照明設備的優點是，因為該設備不需要進行用以經由通信線路而將所有的發射器和所有的照明器材彼此互相連接的構建工程，所以節省了時間和人力。In order to solve the above problems, a lighting apparatus has been proposed which uses infrared rays or the like by simple radio communication (wireless communication) from The transmitter emits a control signal to the lighting fixture to control the lighting fixture. An advantage of such a lighting device is that time and labor are saved because the device does not require a construction work to interconnect all of the transmitters and all of the lighting fixtures to each other via the communication line.
況且，作為該照明設備用的無線電通信方法，在使用紅外線等等來進行通信之外，還提出了一種使用無線電波的方法(例如，參照日本專利公開公告第2006-93049號案)。使用無線電波之通信的優點在於，能夠減少因天線性能所引起之與方向性相關的問題，並且能夠通過諸如牆之類的障礙遮蔽物。Moreover, as a radio communication method for the illuminating device, in addition to communication using infrared rays or the like, a method of using radio waves has been proposed (for example, refer to Japanese Patent Laid-Open Publication No. 2006-93049). The advantage of communication using radio waves is that it is possible to reduce the directionality-related problems caused by the performance of the antenna, and to pass obstacle shields such as walls.
順帶一提，在根據上述無線電通信的習知無線發射器中，有一種無線發射器以例如每5秒一次的預定時間間隔來感測周圍環境明亮度，並根據感測結果來執行對照明器材的開/關控制。即使在周圍環境比由無線發射器本身所開啟的照明器材的預定照度等級亮的情況下，包括有上述習知無線發射器的照明設備會錯誤地判定周圍環境是明亮的。然後，即使在關閉照明器材之後，照明設備也保持該判定的值。由於此，習知照明設備有時會使照明器材不起作用。Incidentally, in the conventional wireless transmitter according to the above radio communication, there is a wireless transmitter that senses ambient brightness at predetermined time intervals, for example, every 5 seconds, and performs lighting equipment according to the sensing result. On/off control. Even in the case where the surrounding environment is brighter than the predetermined illuminance level of the lighting fixture turned on by the wireless transmitter itself, the lighting apparatus including the above-described conventional wireless transmitter erroneously determines that the surrounding environment is bright. Then, even after the lighting fixture is turned off, the lighting device maintains the value of the determination. Because of this, conventional lighting devices sometimes make the lighting fixture inoperative.
為了明確地說明上述問題，考慮如下情況：無線發射器感測到周圍環境明亮度比預定照度等級低，如圖6中的參考符號a所示。In order to clarify the above problem, consider the case where the wireless transmitter senses that the ambient brightness is lower than the predetermined illuminance level, as indicated by reference symbol a in FIG.
在這種情況下，如圖6的參考符號b所示，當感測到有人出現時，無線發射器向接收器發射控制信號，該控制信號包括：作為照度信號的“暗”信號，其表示周圍環境明亮度低於預定的照度等級；以及開啟時間信號，其表示開啟照明器材的開啟時間，例如10秒。回應於該控制信號，接收器將負載輸出升高至高位準，藉以開啟照明器材，並啟動內部計時器，藉以開始對開啟時間進行計數。即使接收到作為照度信號的“亮”信號(表示周圍環境明亮度等於或高於預定亮度等級)，接收器也繼續開啟照明器材，直到由內部計時器所計數的開啟時間經過了由開啟時間信號所表示的時間長度為止。之後，如圖6中的參考符號c和d所示，無線發射器以預定時間間隔感測周圍環境明亮度，並判定周圍環境比由無線發射器本身所開啟的照明器材的預定亮度等級更亮。In this case, as indicated by reference symbol b in FIG. 6, when a person is sensed, the wireless transmitter transmits a control signal to the receiver, the control signal including: a "dark" signal as an illuminance signal, which is represented The ambient brightness is lower than the predetermined illumination level; and the on time signal indicates the turn-on time of the lighting fixture, for example 10 seconds. In response to the control signal, the receiver raises the load output to a high level, thereby turning on the lighting fixture and activating an internal timer to begin counting the turn-on time. Even if a "bright" signal is received as an illuminance signal (indicating that the ambient brightness is equal to or higher than the predetermined brightness level), the receiver continues to turn on the lighting fixture until the turn-on time counted by the internal timer has passed the turn-on time signal The length of time indicated. Thereafter, as indicated by reference symbols c and d in FIG. 6, the wireless transmitter senses the ambient brightness at predetermined time intervals and determines that the surrounding environment is brighter than the predetermined brightness level of the lighting fixture turned on by the wireless transmitter itself. .
然後，如圖6中的參考符號e所示，在接收器中由內部計時器所計數的開啟時間經過了由開啟時間信號所表示的時間長度並且關閉照明器材之後，並且在感測周圍環境明亮度之前，當感測到有人出現時，無線發射器將“亮”信號連同開啟時間信號一起發射到接收器，該“亮”信號是緊接在感測到有人出現之前所判定的明亮度值(即，明亮度判定值)。因此，根據該“亮”信號，接收器保持照明器材的關閉狀態，而不將其開啟。Then, as indicated by reference symbol e in Fig. 6, the turn-on time counted by the internal timer in the receiver passes the length of time indicated by the turn-on time signal and the lighting fixture is turned off, and the surrounding environment is brightened. Before the degree, when a person is sensed, the wireless transmitter transmits a "bright" signal along with the turn-on time signal to the receiver, the "bright" signal being the brightness value determined immediately before sensing the presence of someone. (ie, brightness determination value). Thus, based on this "bright" signal, the receiver maintains the off state of the lighting fixture without turning it on.
如上所述，習知照明設備的問題在於，即使在感測到有人出現並因此有必要開啟照明器材的情況下，在無線發 射器下一次感測周圍環境明亮度之前，也無法開啟照明器材。As described above, the conventional lighting device has a problem in that wireless transmission is performed even in the case where it is sensed that a person appears and it is necessary to turn on the lighting fixture. The lighting fixture cannot be turned on until the next time the projector senses the brightness of the surrounding environment.
在這種情況下，已提出了本發明，以便解決上述問題。本發明之目的在於提供一種熱射線式無線發射器，其能夠防止照明器材在錯誤地判定周圍環境比無線發射器本身所開啟的照明器材的預定亮度等級亮的情況下不起作用；以及提供一種無線接收器，用以接收從無線發射器所發射出的無線電信號，並控制照明器材。Under the circumstances, the present invention has been made in order to solve the above problems. It is an object of the present invention to provide a heat ray type wireless transmitter capable of preventing a lighting fixture from functioning in the case of erroneously determining that the surrounding environment is brighter than a predetermined brightness level of a lighting fixture turned on by the wireless transmitter itself; A wireless receiver for receiving radio signals transmitted from the wireless transmitter and controlling the lighting fixture.
根據本發明的熱射線式無線發射器以下面的方式來實現上述目的。明確地說，當人物感測器感測到有人出現時，無線發射器產生及輸出包括有照度信號和開啟時間信號的控制信號，並在輸出該控制信號的同時，啟動無線發射器本身的內部計時器，藉以對由開啟時間信號所表示的開啟時間進行計數，其中照度信號表示根據從明亮度感測器所供應的感測信號的周圍環境明亮度，開啟時間信號表示開啟照明器材的開啟時間。然後，緊接在內部計時器結束計數之後，無線發射器獲取由明亮度感測器所感測到的周圍環境明亮度。The heat ray type wireless transmitter according to the present invention achieves the above object in the following manner. Specifically, when the person sensor senses that someone is present, the wireless transmitter generates and outputs a control signal including an illuminance signal and an on-time signal, and activates the interior of the wireless transmitter itself while outputting the control signal. a timer for counting the turn-on time indicated by the turn-on time signal, wherein the illuminance signal indicates the ambient brightness according to the sensed signal supplied from the brightness sensor, and the turn-on time signal indicates the turn-on time of the turn-on lighting device . Then, immediately after the internal timer ends counting, the wireless transmitter acquires the ambient brightness sensed by the brightness sensor.

下面將參照附圖，描述本發明的實施例。Embodiments of the present invention will be described below with reference to the accompanying drawings.
例如，如圖1所示，本實施例是對安裝在各個房間、走廊等地點的多個照明器材進行控制的照明設備。在該照明設備中，每一個無線發射器10以預定的時間間隔來感測周圍環境明亮度。當感測到有人在感測區域中出現時，該照明設備通過使用紅外線等的無線電通信向接收器20發射包括照度信號和開啟時間信號的控制信號，其中照度信號表示周圍環境明亮度，開啟時間信號表示開啟每一個照明器材的開啟時間。這樣，照明設備控制相關的照明器材。For example, as shown in FIG. 1, this embodiment is a lighting device that controls a plurality of lighting fixtures installed in various rooms, corridors, and the like. In the illumination device, each wireless transmitter 10 senses ambient brightness at predetermined time intervals. When it is sensed that a person appears in the sensing area, the lighting device transmits a control signal including an illuminance signal and an on-time signal to the receiver 20 by radio communication using infrared rays or the like, wherein the illuminance signal indicates ambient brightness, opening time The signal indicates the turn-on time of each lighting fixture. In this way, the lighting device controls the associated lighting fixtures.
注意，圖1顯示出安裝有兩個無線發射器10a和10b的狀態。在這種安裝模式的情況下，例如，當有人從起居室和組合在一起的餐廳和廚房(以下簡稱“LDK”)通過入口出門時，安裝在走廊處的無線發射器10a感測到有人出現。這樣，無線發射器10a輸出控制信號，以開啟LDK的照明器材，然後順利地開啟入口處的照明器材。此外， 在圖1中，例如，當有人從屋外進入入口之後走向LDK時，安裝在入口處的無線發射器10b感測到有人出現。這樣，無線發射器10b輸出控制信號，以開啟入口的照明器材，然後順利地開啟LDK的照明器材。Note that Fig. 1 shows a state in which two wireless transmitters 10a and 10b are mounted. In the case of this installation mode, for example, when someone comes out from the living room and the combined restaurant and kitchen (hereinafter referred to as "LDK") through the entrance, the wireless transmitter 10a installed at the corridor senses that someone has appeared. . Thus, the wireless transmitter 10a outputs a control signal to turn on the lighting fixture of the LDK and then smoothly turn on the lighting fixture at the entrance. In addition, In Fig. 1, for example, when a person walks into the LDK after entering the entrance from outside the house, the wireless transmitter 10b installed at the entrance senses the presence of a person. Thus, the wireless transmitter 10b outputs a control signal to turn on the lighting fixture of the entrance and then smoothly turn on the lighting fixture of the LDK.
如圖2所示，無線發射器10包括：電源11，其供應驅動電力；人物感測器12，其感測是否有人出現；明亮度感測器13，其感測環境明亮度；控制單元14，其產生控制信號；開關15，其根據由控制單元14所產生的控制信號而進行工作；以及紅外線發光二極體(LEDs)16，其發射紅外線。As shown in FIG. 2, the wireless transmitter 10 includes: a power source 11 that supplies driving power; a person sensor 12 that senses whether a person is present; a brightness sensor 13 that senses ambient brightness; and the control unit 14 And generating a control signal; a switch 15 that operates in accordance with a control signal generated by the control unit 14; and infrared light emitting diodes (LEDs) 16 that emit infrared light.
例如，電源11包括電池。該電源11向上述無線發射器10供應驅動電力。For example, the power source 11 includes a battery. The power source 11 supplies drive power to the wireless transmitter 10 described above.
例如，人物感測器12包括熱電元件等，並藉由感測在感測區域中出現的人體所輻射出的熱射線來感測是否有人出現。當人物感測器12感測到有人出現時，向控制單元14供應因而所產生的感測信號。For example, the person sensor 12 includes a pyroelectric element or the like, and senses whether or not a person appears by sensing a heat ray radiated from a human body appearing in the sensing area. When the person sensor 12 senses the presence of a person, the control unit 14 is supplied with the thus generated sensing signal.
例如，明亮度感測器13包括光電晶體等，並感測環境明亮度。將明亮度感測器13的感測信號供應給控制單元14。For example, the brightness sensor 13 includes a photoelectric crystal or the like and senses ambient brightness. The sensing signal of the brightness sensor 13 is supplied to the control unit 14.
例如，控制單元14包括微電腦等。從人物感測器12向控制單元14供應感測信號。當從人物感測器12供應來感測信號時，控制單元14根據從明亮度感測器13所供應的感測信號而產生包括照度信號和開啟時間信號的控制信號，其中照度信號表示周圍環境明亮度，開啟時間信號表 示開啟每一個照明器材的開啟時間。然後，控制單元14將所產生的控制信號供應給開關15。For example, the control unit 14 includes a microcomputer or the like. A sensing signal is supplied from the person sensor 12 to the control unit 14. When the sensing signal is supplied from the person sensor 12, the control unit 14 generates a control signal including an illuminance signal and an on-time signal based on the sensing signal supplied from the brightness sensor 13, wherein the illuminance signal indicates the surrounding environment Brightness, on time signal table Shows the opening time of each lighting fixture. Control unit 14 then supplies the generated control signal to switch 15.
此外，雖然並未特別例舉出，但是控制單元14中包括對時間進行計數的計時器。控制單元14在輸出控制信號的同時啟動該計時器。該計時器對開啟時間信號所指表的開啟時間進行計數。Further, although not specifically exemplified, the control unit 14 includes a timer that counts time. The control unit 14 activates the timer while outputting the control signal. This timer counts the turn-on time of the table indicated by the turn-on time signal.
此外，在輸出控制信號之後，控制單元14根據從人物感測器12所供應的感測信號或分別從人物感測器12和明亮度感測器13所供應的感測信號來產生作為控制信號的延長信號，該延長信號用以延長每一個照明器材的開啟時間。明確地說，當照明設備是不管環境明亮度如何只要有人出現就持續開啟照明器材的類型時，控制單元14只根據從人物感測器12所供應的感測信號來產生延長信號。此外，當照明設備是只在環境明亮度低於預定亮度等級(例如，在夜間等)並且有人出現時才持續開啟照明器材的類型時，控制單元14根據分別從人物感測器12和明亮度感測器13所供應的感測信號而產生延長信號。然後，控制單元14向開關15供應所產生的延長信號。Further, after outputting the control signal, the control unit 14 generates as a control signal based on the sensing signal supplied from the person sensor 12 or the sensing signals supplied from the person sensor 12 and the brightness sensor 13, respectively. The extension signal is used to extend the opening time of each lighting fixture. In particular, when the lighting device is of a type that continuously turns on the lighting fixture whenever there is a person regardless of the brightness of the environment, the control unit 14 generates the extension signal based only on the sensing signal supplied from the person sensor 12. Further, when the lighting device is of a type that continuously turns on the lighting fixture only when the ambient brightness is lower than a predetermined brightness level (for example, at night, etc.) and a person appears, the control unit 14 is based on the character sensor 12 and the brightness, respectively. The sensing signal supplied from the sensor 13 generates an extended signal. Then, the control unit 14 supplies the generated extension signal to the switch 15.
例如，開關15包括諸如電晶體之類的開關元件。開關15根據由控制單元14所產生的控制信號而進行工作，以開啟紅外線LEDs 16。For example, the switch 15 includes a switching element such as a transistor. The switch 15 operates in accordance with a control signal generated by the control unit 14 to turn on the infrared LEDs 16.
紅外線LEDs 16在開關15的驅動之後發射紅外線，開關15的驅動根據由控制單元14所產生的控制信號。這樣，紅外線LEDs 16輸出這種控制信號作為紅外線。由紅 外線LEDs 16所發射出的每一個控制信號經由紅外線通信而到達接收器20。這樣，紅外線LEDs 16控制照明器材。The infrared LEDs 16 emit infrared rays after the driving of the switch 15, and the driving of the switch 15 is based on a control signal generated by the control unit 14. Thus, the infrared LEDs 16 output such a control signal as infrared rays. By red Each control signal emitted by the outside line LEDs 16 reaches the receiver 20 via infrared communication. Thus, the infrared LEDs 16 control the lighting fixture.
包括上述無線發射器10的照明設備緊接在相關無線發射器10中的控制單元14的內部計時器完成計數之後，經由明亮度感測器13來感測周圍環境明亮度，藉以防止照明器材不起作用。The illumination device including the wireless transmitter 10 described above senses the brightness of the surrounding environment via the brightness sensor 13 immediately after the internal timer of the control unit 14 in the associated wireless transmitter 10 completes counting, thereby preventing the lighting device from being kick in.
明確地說，在明亮度感測器13感測到周圍環境明亮度低於預定亮度等級之後，如圖3中的參考符號所示，無線發射器10經由人物感測器12而感測到有人出現(如圖3中的參考符號b所示)。此時，在控制單元14的控制下，無線發射器10向接收器發射控制信號，該控制信號包括：“暗”信號，作為照度信號，表示周圍環境明亮度低於預定亮度等級；以及開啟時間信號，表示開啟相關照明器材的開啟時間，例如10秒。回應於該控制信號，接收器20將負載輸出升高至高位準，以開啟照明器材，並啟動接收器20本身的內部計時器，以開始對開啟時間進行計數。即使接收到表示周圍環境明亮度等於或高於預定亮度等級的“亮”信號作為照度信號，接收器20也繼續開啟照明器材，直到由內部計時器計數的開啟時間經過了開啟時間信號所指示的時間長度為止。In particular, after the brightness sensor 13 senses that the ambient brightness is lower than the predetermined brightness level, the wireless transmitter 10 senses someone via the person sensor 12 as indicated by the reference symbol in FIG. Appears (as indicated by reference symbol b in Figure 3). At this time, under the control of the control unit 14, the wireless transmitter 10 transmits a control signal to the receiver, the control signal including: a "dark" signal, as an illuminance signal, indicating that the ambient brightness is lower than a predetermined brightness level; and the opening time Signal, indicating the turn-on time of the relevant lighting fixture, for example 10 seconds. In response to the control signal, the receiver 20 raises the load output to a high level to turn on the lighting fixture and activates the internal timer of the receiver 20 itself to begin counting the turn-on time. Even if a "bright" signal indicating that the ambient brightness is equal to or higher than the predetermined brightness level is received as the illuminance signal, the receiver 20 continues to turn on the lighting fixture until the on time counted by the internal timer passes the indication of the on time signal The length of time.
同時，如圖3中的參考符號c和d所示，在控制單元14的控制下，無線發射器10以例如每5秒一次的預定時間間隔，經由明亮度感測器13來感測周圍環境明亮度， 並判定周圍環境比無線發射器10本身所開啟的照明器材的預定亮度等級亮。Meanwhile, as indicated by reference symbols c and d in FIG. 3, under the control of the control unit 14, the wireless transmitter 10 senses the surrounding environment via the brightness sensor 13 at predetermined time intervals, for example, every 5 seconds. Brightness, It is also determined that the surrounding environment is brighter than the predetermined brightness level of the lighting fixture that the wireless transmitter 10 itself is turned on.
然後，如圖3中的參考符號e所示，在控制單元14的控制下，無線發射器10緊接在內部計時器結束計數之後，通過明亮度感測器13感測周圍環境明亮度。在這種情況下，無線發射器10通過明亮度感測器13感測到周圍環境明亮度低於預定亮度等級，這是因為當前狀態是在內部計時器結束計數之後的狀態，此時由無線發射器10本身所開啟的照明器材已熄滅。然後，如圖3中的參考符號f所示，當人物感測器12感測到有人出現時，無線發射器10在控制單元14的控制下向接收器20發射控制信號，該控制信號包括：“暗”信號，作為緊接在感測到有人出現之前的明亮度判定值；以及開啟時間信號，表示開啟照明器材的開啟時間。回應於該控制信號，接收器20將負載輸出升高至高位準，以開啟照明器材，並啟動內部計時器，以開始對開啟時間進行計數。Then, as indicated by reference symbol e in FIG. 3, under the control of the control unit 14, the wireless transmitter 10 senses ambient brightness through the brightness sensor 13 immediately after the internal timer ends counting. In this case, the wireless transmitter 10 senses that the ambient brightness is lower than the predetermined brightness level by the brightness sensor 13, because the current state is the state after the internal timer ends counting, at this time by wireless The lighting fixture that is turned on by the transmitter 10 itself is extinguished. Then, as indicated by reference symbol f in FIG. 3, when the person sensor 12 senses the presence of a person, the wireless transmitter 10 transmits a control signal to the receiver 20 under the control of the control unit 14, the control signal comprising: A "dark" signal, as a brightness determination value immediately before sensing the presence of a person; and an on time signal indicating an on time of turning on the lighting fixture. In response to the control signal, the receiver 20 raises the load output to a high level to turn on the lighting fixture and activates an internal timer to begin counting the turn-on time.
如上所述，緊接在無線發射器10中的控制單元14的內部計時器完成計數之後，照明設備通過控制單元14獲取由明亮度感測器13所感測到的周圍環境明亮度。這樣，即使緊接在內部計時器結束計數之後(例如，在其後的一秒內)，照明設備也可以在經由人物感測器12感測到有人出現時確切地開啟照明器材。As described above, immediately after the internal timer of the control unit 14 in the wireless transmitter 10 finishes counting, the illumination device acquires the ambient brightness sensed by the brightness sensor 13 through the control unit 14. Thus, even after the internal timer ends counting (eg, within one second thereafter), the lighting device can turn the lighting fixture on exactly when a person is sensed via the person sensor 12.
在此，照明設備可能導致無線發射器10的內部計時器與接收器20的內部計時器之間的誤差。因此，由於該 誤差，在照明設備中會出現如下情況：即使根據無線發射器10的內部計時器，到了必須關閉照明器材的時間，照明器材根據接收器20的內部計時器而依然保持開啟。在這種情況下，在照明設備中可能出現如下情況：當照明器材保持開啟時，照明設備經由明亮度感測器13感測周圍環境明亮度，並錯誤地輸出“亮”信號作為照度信號，所以無法正確地控制照明器材。Here, the illumination device may cause an error between the internal timer of the wireless transmitter 10 and the internal timer of the receiver 20. Therefore, because of this The error, in the lighting device, can occur that even if the lighting fixture is turned off according to the internal timer of the wireless transmitter 10, the lighting fixture remains open according to the internal timer of the receiver 20. In this case, a situation may occur in the lighting device that when the lighting fixture remains turned on, the lighting device senses ambient brightness via the brightness sensor 13 and erroneously outputs a "bright" signal as an illuminance signal, Therefore, the lighting equipment cannot be properly controlled.
因此，無線發射器10提供了預定時間(例如，緊接在控制單元14的內部計時器結束計數之後的一秒內)作為用於吸收上述誤差的誤差吸收時間。這樣，希望在該誤差吸收時間之內感測到有人出現的情況下，無線發射器10保持待機而不發射控制信號，而在明亮度感測器13感測明亮度之後才發射控制信號。Therefore, the wireless transmitter 10 is provided for a predetermined time (for example, within one second immediately after the internal timer of the control unit 14 ends counting) as the error absorption time for absorbing the above error. Thus, in the event that it is desired to sense the presence of a person within the error absorption time, the wireless transmitter 10 remains on standby without transmitting a control signal, and the control signal is transmitted after the brightness sensor 13 senses the brightness.
明確地說，在明亮度感測器13感測到周圍環境明亮度低於預定亮度等級(如圖4中的參考符號a所示)之後，無線發射器10經由人物感測器12而感測到有人出現，如圖4中的參考符號b所示。然後，在控制單元14的控制下，無線發射器10向接收器發射控制信號，該控制信號包括：“暗”信號，作為照度信號，表示周圍環境明亮度低於預定亮度等級；以及開啟時間信號，表示開啟相關照明器材的開啟時間，例如10秒。回應於該控制信號，接收器20將負載輸出升高至高位準，以開啟照明器材，並啟動接收器20本身的內部計時器，以開始對開啟時間進行計數。即使接收到表示周圍環境明亮度等於或高 於預定亮度等級的“亮”信號作為照度信號，接收器20也繼續開啟照明器材，直到由內部計時器計數的開啟時間經過了開啟時間信號所表示的時間長度為止。In particular, after the brightness sensor 13 senses that the ambient brightness is lower than a predetermined brightness level (as indicated by reference symbol a in FIG. 4), the wireless transmitter 10 senses via the person sensor 12. When someone appears, as shown by reference symbol b in Figure 4. Then, under the control of the control unit 14, the wireless transmitter 10 transmits a control signal to the receiver, the control signal comprising: a "dark" signal as an illuminance signal indicating that the ambient brightness is lower than a predetermined brightness level; and an on time signal , indicating the opening time of the relevant lighting fixture, for example 10 seconds. In response to the control signal, the receiver 20 raises the load output to a high level to turn on the lighting fixture and activates the internal timer of the receiver 20 itself to begin counting the turn-on time. Even if it receives a brightness indicating that the surrounding environment is equal to or high The "bright" signal at the predetermined brightness level is used as the illuminance signal, and the receiver 20 also continues to turn on the lighting fixture until the turn-on time counted by the internal timer has passed the length of time indicated by the turn-on time signal.
此時，如圖4中的參考符號c和d所示，在控制單元14的控制下，無線發射器10以例如每5秒一次的預定時間間隔，經由明亮度感測器13來感測周圍環境明亮度，並判定周圍環境比無線發射器10本身所開啟的照明器材的預定亮度等級亮。At this time, as indicated by reference symbols c and d in FIG. 4, under the control of the control unit 14, the wireless transmitter 10 senses the surroundings via the brightness sensor 13 at predetermined time intervals, for example, every 5 seconds. The ambient brightness is determined, and the surrounding environment is determined to be brighter than the predetermined brightness level of the lighting fixture that the wireless transmitter 10 itself is turned on.
然後，緊接在內部計時器結束計數之後，無線發射器10並不經由明亮度感測器13感測周圍環境明亮度，而是如圖4中的參考符號e所示，在控制器14的控制下，經過了作為誤差吸收時間的一秒之後，才經由明亮度感測器13感測周圍環境明亮度。在這種情況下，無線發射器10經由明亮度感測器13感測到周圍環境明亮度低於預定亮度等級，這是因為當前狀態是在內部計時器結束計數之後的狀態，此時由無線發射器10所開啟的照明器材已熄滅。然後，在誤差吸收時間之內，當人物感測器12感測到有人出現時，如圖4中的參考符號f所示，無線發射器10在控制單元14的控制下向接收器20發射控制信號，該控制信號包括：“暗”信號，作為如圖4中的參考符號e所示的定時處的明亮度判定值；以及開啟時間信號，表示開啟照明器材的開啟時間。回應於該控制信號，接收器20再次將負載輸出升高至高位準，以開啟照明器材，並啟動內部計時器，以開始對開啟時間進行計數。Then, immediately after the internal timer ends counting, the wireless transmitter 10 does not sense the ambient brightness via the brightness sensor 13, but instead is shown in reference numeral e in FIG. Under control, the brightness of the surrounding environment is sensed via the brightness sensor 13 after one second as the error absorption time. In this case, the wireless transmitter 10 senses that the ambient brightness is lower than the predetermined brightness level via the brightness sensor 13, because the current state is the state after the internal timer ends counting, at this time by wireless The lighting fixture turned on by the transmitter 10 is extinguished. Then, within the error absorption time, when the person sensor 12 senses the presence of a person, the wireless transmitter 10 transmits control to the receiver 20 under the control of the control unit 14 as indicated by reference symbol f in FIG. A signal including: a "dark" signal as a brightness determination value at a timing as indicated by reference symbol e in FIG. 4; and an on-time signal indicating an on-time of turning on the lighting fixture. In response to the control signal, the receiver 20 again raises the load output to a high level to turn on the lighting fixture and activates an internal timer to begin counting the turn-on time.
如上所述，照明設備在無線發射器10中的控制單元14的內部計時器結束計數之後提供預定誤差吸收時間。接著，在該誤差吸收時間之內感測到有人出現的情況下，照明設備保持待機而不發射控制信號，接著在獲取由明亮度感測器13感測到的周圍環境明亮度之後，發射控制信號。這樣，即使在無線發射器10的內部計時器與接收器20的內部計時器之間出現誤差的情況下，照明設備也可以適當地控制照明器材。As described above, the illumination device provides a predetermined error absorption time after the internal timer of the control unit 14 in the wireless transmitter 10 ends counting. Then, in the case where a person is sensed within the error absorption time, the illumination device remains in standby without transmitting a control signal, and then after acquiring the brightness of the surrounding environment sensed by the brightness sensor 13, the emission control signal. Thus, even in the event of an error between the internal timer of the wireless transmitter 10 and the internal timer of the receiver 20, the lighting device can appropriately control the lighting fixture.
注意，在採用該方法的情況下，最多出現大約一秒的時間滯後，並且照明設備會引起用戶的不適感。Note that in the case of adopting this method, a time lag of about one second occurs at most, and the lighting device causes discomfort to the user.
在這種情況下，當無線發射器10的內部計時器根據作為照度信號的“暗”信號而開始執行計數時，並且當人物感測器12在誤差吸收時間之內感測到有人出現時，無線發射器10可以向接收器20發射照度信號，在該照度信號中，明亮度判定值被重寫為“暗”。In this case, when the internal timer of the wireless transmitter 10 starts counting according to the "dark" signal as the illuminance signal, and when the person sensor 12 senses that a person appears within the error absorbing time, The wireless transmitter 10 can transmit an illuminance signal to the receiver 20, in which the brightness determination value is rewritten as "dark".
明確地說，在明亮度感測器13感測到周圍環境明亮度低於預定亮度等級時，如圖5中的參考符號a所示，無線發射器10經由人物感測器12感測到有人出現，如圖4中的參考符號b所示。然後，在控制單元14的控制下，無線發射器10向接收器發射控制信號，該控制信號包括：“暗”信號，作為照度信號，表示周圍環境明亮度低於預定亮度等級；以及開啟時間信號，表示開啟相關照明器材的開啟時間，例如10秒。回應於該控制信號，接收器20將負載輸出升高至高位準，以開啟照明器材，並啟 動接收器20本身的內部計時器，以開始對開啟時間進行計數。即使接收到表示周圍環境明亮度等於或高於預定亮度等級的“亮”信號作為照度信號，接收器20也繼續開啟照明器材，直到由內部計時器計數的開啟時間經過了開啟時間信號所表示的時間長度為止。Specifically, when the brightness sensor 13 senses that the ambient brightness is lower than the predetermined brightness level, the wireless transmitter 10 senses someone via the person sensor 12 as indicated by reference symbol a in FIG. Appears as shown by reference symbol b in FIG. Then, under the control of the control unit 14, the wireless transmitter 10 transmits a control signal to the receiver, the control signal comprising: a "dark" signal as an illuminance signal indicating that the ambient brightness is lower than a predetermined brightness level; and an on time signal , indicating the opening time of the relevant lighting fixture, for example 10 seconds. In response to the control signal, the receiver 20 raises the load output to a high level to turn on the lighting fixture and initiate The internal timer of the receiver 20 itself is started to count the on time. Even if a "bright" signal indicating that the ambient brightness is equal to or higher than the predetermined brightness level is received as the illuminance signal, the receiver 20 continues to turn on the lighting fixture until the turn-on time counted by the internal timer passes the on-time signal The length of time.
同時，如圖5中的參考符號c和d所示，在控制單元14的控制下，無線發射器10以例如每5秒一次的預定時間間隔經由明亮度感測器13感測周圍環境明亮度，並判定周圍環境比無線發射器10本身所開啟的照明器材的預定亮度等級亮。Meanwhile, as indicated by reference symbols c and d in FIG. 5, under the control of the control unit 14, the wireless transmitter 10 senses ambient brightness via the brightness sensor 13 at predetermined time intervals, for example, every 5 seconds. And determining that the surrounding environment is brighter than the predetermined brightness level of the lighting fixture that the wireless transmitter 10 itself is turned on.
然後，當無線發射器10的內部計時器結束計數，並且人物感測器12在誤差吸收時間之內感測到有人出現時，如圖5中的參考符號e所示，無線發射器10在控制單元14的控制下向接收器20發射控制信號，該控制信號包括：照度信號，其中將明亮度判定值強制地重寫為“暗”；以及開啟時間信號，表示開啟照明器材的開啟時間。回應於該控制信號，接收器20再次將負載輸出升高至高位準，以開啟照明器材，並啟動內部計時器，以開始對開啟時間進行計數。Then, when the internal timer of the wireless transmitter 10 ends counting and the person sensor 12 senses that a person has appeared within the error absorption time, as shown by reference symbol e in FIG. 5, the wireless transmitter 10 is controlling The control of the unit 14 transmits a control signal to the receiver 20, the control signal comprising: an illuminance signal, wherein the brightness determination value is forcibly rewritten to "dark"; and an on time signal indicating the on time of turning on the lighting fixture. In response to the control signal, the receiver 20 again raises the load output to a high level to turn on the lighting fixture and activates an internal timer to begin counting the turn-on time.
如上所述，在該誤差吸收時間之內感測到有人出現的情況下，照明設備向接收器20發射照度信號，在該照度信號中明亮度判定值被重寫為“暗”。這樣，即使在自動關閉照明器材之後，照明設備也可以在幾乎沒有時間滯後的狀態下立即開啟照明器材，並可以增強用戶的安全感。As described above, in the case where a person is sensed within the error absorption time, the illumination device transmits an illuminance signal to the receiver 20, in which the brightness determination value is rewritten as "dark". In this way, even after the lighting fixture is automatically turned off, the lighting device can immediately turn on the lighting fixture with almost no time lag, and can enhance the user's sense of security.
注意，當不必靈活地改變感測明亮度的地點時，照明設備可以在接收器20側而不是在無線發射器10側提供功能與明亮度感測器13相似的明亮度感測器。明確地說，接收器20從無線發射器10接收控制信號，該控制信號包括開啟時間信號，用以表示開啟照明器材的開啟時間。然後，在接收器20中的控制單元(未示出)的控制下，接收器20根據開啟時間信號和從明亮度感測器所供應的感測信號來控制照明器材，並在接收到控制信號的同時啟動內部計時器，藉以對開啟時間信號所表示的開啟時間進行計數。然後，在控制單元的控制下，接收器20緊接在內部計時器結束計數之後獲取由明亮度感測器所感測到的周圍環境明亮度。Note that the illumination device can provide a brightness sensor similar in function to the brightness sensor 13 on the side of the receiver 20 instead of the side of the wireless transmitter 10 when it is not necessary to flexibly change the location where the brightness is sensed. In particular, the receiver 20 receives a control signal from the wireless transmitter 10, the control signal including an on time signal to indicate the turn-on time to turn on the lighting fixture. Then, under the control of a control unit (not shown) in the receiver 20, the receiver 20 controls the lighting fixture according to the turn-on time signal and the sensing signal supplied from the brightness sensor, and receives the control signal At the same time, an internal timer is started to count the on time indicated by the on time signal. Then, under the control of the control unit, the receiver 20 acquires the ambient brightness sensed by the brightness sensor immediately after the internal timer ends counting.
在使用上述接收器20的情況下，照明設備只需要經由無線發射器10發射開啟時間信號，因此，不必執行上述複雜的操作。In the case of using the above-described receiver 20, the lighting device only needs to transmit the turn-on time signal via the wireless transmitter 10, and therefore, it is not necessary to perform the above-described complicated operation.
此外，在接收器20側，連同明亮度感測器一起，照明設備可以提供手動開關等，該手動開關作為用以對開啟時間進行設定的設定單元。明確地說，在控制單元(未顯示出)的控制下，接收器20根據由手動開關所設定的開啟時間和從明亮度感測器所供應的感測信號來控制照明器材，並在接收到感測信號的同時啟動內部計時器，藉以對手動開關所設定的開啟時間進行計數。然後，在控制單元的控制下，接收器20緊接在內部計時器結束計數之後獲取由明亮度感測器所感測的周圍環境明亮度。Further, on the receiver 20 side, together with the brightness sensor, the lighting device can provide a manual switch or the like as a setting unit for setting the opening time. Specifically, under the control of a control unit (not shown), the receiver 20 controls the lighting fixture according to the opening time set by the manual switch and the sensing signal supplied from the brightness sensor, and is received upon receiving The internal timer is activated at the same time as the signal is sensed, thereby counting the turn-on time set by the manual switch. Then, under the control of the control unit, the receiver 20 acquires the ambient brightness sensed by the brightness sensor immediately after the internal timer ends counting.
在使用上述接收器20的情況下，不必由無線發射器10發射照度信號和開啟時間信號二者，因此，照明設備可以簡化信號，並且可以降低功耗。此外，即使在大量地點安裝無線發射器10的情況下，照明設備也可以顯著減少如下情況：這些信號彼此重疊，接收器20無法識別相關信號。In the case of using the above-described receiver 20, it is not necessary to transmit both the illuminance signal and the on-time signal by the wireless transmitter 10, and therefore, the illumination device can simplify the signal and can reduce power consumption. Moreover, even in the case where the wireless transmitter 10 is installed in a large number of locations, the lighting device can significantly reduce the situation where the signals overlap each other and the receiver 20 cannot recognize the relevant signals.
此外，在接收器20側，連同明亮度感測器一起提供用於設定開啟時間的手動開關等的情況下，照明設備可以分別設定：在根據從無線發射器10所發射出的控制信號而開啟照明器材的情況下的開啟時間；以及在根據由手動開關所設定的開啟時間和從明亮度感測器所供應的感測信號而開啟照明器材的情況下的開啟時間。這樣，照明設備可以分別設定由無線發射器10暫時開啟照明器材的開啟時間、以及由接收器20(手動開關)暫時開啟照明器材的開啟時間，並可以增強可用性。Further, in the case of the receiver 20 side, together with the brightness sensor providing a manual switch or the like for setting the turn-on time, the illumination device can be separately set to be turned on in accordance with a control signal transmitted from the wireless transmitter 10. The turn-on time in the case of the lighting fixture; and the turn-on time in the case where the lighting fixture is turned on according to the turn-on time set by the manual switch and the sensing signal supplied from the brightness sensor. In this way, the lighting device can separately set the opening time of the lighting fixture temporarily turned on by the wireless transmitter 10, and the opening time of the lighting fixture temporarily turned on by the receiver 20 (manual switch), and can enhance the usability.
如上具體所述，在根據本發明實施例的照明設備中，當人物感測器12感測到有人出現時，無線發射器10在控制單元14的控制下產生並輸出控制信號，該控制信號包括：照度信號，表示根據從明亮度感測器13所供應的感測信號的周圍環境明亮度；以及開啟時間信號，表示開啟照明器材的開啟時間。此外，在輸出控制信號的同時，無線發射器10啟動其內部計時器，並對開啟時間信號所表示的開啟時間進行計數。然後，在控制單元14的控制下，無線發射器10緊接在內部計時器結束計數之後獲取 由明亮度感測器13所感測到的周圍環境明亮度。As described above, in the lighting apparatus according to the embodiment of the present invention, when the person sensor 12 senses the presence of a person, the wireless transmitter 10 generates and outputs a control signal under the control of the control unit 14, the control signal including The illuminance signal indicates the ambient brightness according to the sensing signal supplied from the brightness sensor 13; and the opening time signal indicates the opening time of the lighting fixture. In addition, while outputting the control signal, the wireless transmitter 10 activates its internal timer and counts the turn-on time indicated by the turn-on time signal. Then, under the control of the control unit 14, the wireless transmitter 10 acquires immediately after the internal timer ends counting. The brightness of the surrounding environment sensed by the brightness sensor 13.
這樣，根據該照明設備，即使緊接在無線發射器10的內部計時器結束計數之後人物感測器12感測到有人出現時，也可以確切地開啟照明器材。Thus, according to the lighting device, even if the person sensor 12 senses that a person is present immediately after the internal timer of the wireless transmitter 10 ends counting, the lighting fixture can be turned on exactly.
此外，在無線發射器10中，當人物感測器12在控制單元14的內部計時器結束計數之後的預定時間內感測到有人出現時，控制單元14可以保持待機而不輸出控制信號，並可以在獲取由明亮度感測器13所感測到的周圍環境明亮度之後輸出控制信號。這樣，根據該照明設備，即使在無線發射器10的內部計時器與接收器20的內部計時器之間出現誤差的情況下，也可以適當地控制照明器材。Further, in the wireless transmitter 10, when the person sensor 12 senses that a person has appeared within a predetermined time after the internal timer of the control unit 14 ends counting, the control unit 14 can remain on standby without outputting a control signal, and The control signal may be output after acquiring the ambient brightness sensed by the brightness sensor 13. Thus, according to the lighting device, even in the case where an error occurs between the internal timer of the wireless transmitter 10 and the internal timer of the receiver 20, the lighting fixture can be appropriately controlled.
此外，在無線發射器10中，當人物感測器12在控制單元14的內部計時器結束計數之後的預定時間內感測到有人出現時，控制單元14輸出照度信號，在該照度信號中，明亮度判定值被強制重寫。這樣，即使在照明器材自動關閉之後，無線發射器10也可以在幾乎沒有時間滯後的狀態下立即開啟照明器材，並可以增強用戶的安全感。Further, in the wireless transmitter 10, when the person sensor 12 senses that a person has appeared within a predetermined time after the internal timer of the control unit 14 ends counting, the control unit 14 outputs an illuminance signal, in which the illuminance signal, The brightness determination value is forcibly rewritten. Thus, even after the lighting fixture is automatically turned off, the wireless transmitter 10 can immediately turn on the lighting fixture with almost no time lag, and can enhance the user's sense of security.
此外，根據該照明設備，可以在接收器20側提供明亮度感測器。在這種情況下，當從無線發射器10接收到包括對開啟照明器材的開啟時間進行所表示的開啟時間信號的控制信號時，接收器20根據開啟時間信號和從明亮度感測器所供應的感測信號來控制照明器材。在接收到控制信號的同時，接收器20啟動內部計時器，從而對開啟時間信號所指示的開啟時間進行計數。然後，接收器20 緊接在內部計時器結束計數之後獲取由明亮度感測器所感測到的周圍環境明亮度。Further, according to the lighting device, a brightness sensor can be provided on the side of the receiver 20. In this case, when receiving a control signal including the turn-on time signal indicated by the turn-on time of turning on the lighting fixture from the wireless transmitter 10, the receiver 20 supplies it according to the turn-on time signal and from the brightness sensor. The sensing signal controls the lighting fixture. While receiving the control signal, the receiver 20 activates an internal timer to count the on time indicated by the on time signal. Then, the receiver 20 The ambient brightness sensed by the brightness sensor is acquired immediately after the internal timer ends counting.
這樣，根據該照明設備，無線發射器10只需要發射開啟時間信號，因此不必執行複雜的操作。Thus, according to the lighting device, the wireless transmitter 10 only needs to transmit the turn-on time signal, so it is not necessary to perform complicated operations.
此外，在接收器20側，該照明設備不僅可以提供明亮度感測器，還可以提供例如手動開關之類的設定單元，該設定單元用以設定開啟照明器材的開啟時間。在這種情況下，接收器20根據由設定單元所設定的開啟時間和從明亮度感測器所供應的感測信號來控制照明器材，並在接收到感測信號的同時啟動內部計時器，藉以對由設定單元所設定的開啟時間進行計數。然後，接收器20緊接在內部計時器結束計數之後獲取由明亮度感測器所感測的周圍環境明亮度。In addition, on the side of the receiver 20, the lighting device can provide not only a brightness sensor but also a setting unit such as a manual switch for setting the opening time of the lighting fixture. In this case, the receiver 20 controls the lighting fixture according to the opening time set by the setting unit and the sensing signal supplied from the brightness sensor, and starts the internal timer while receiving the sensing signal, Thereby counting the on time set by the setting unit. The receiver 20 then acquires the ambient brightness sensed by the brightness sensor immediately after the internal timer ends counting.
這樣，不必由無線發射器10發射照度信號和開啟時間信號二者，因此，照明設備可以簡化信號，並且可以降低功耗。此外，即使在大量地點安裝無線發射器10的情況下，照明設備也可以顯著減少如下情況：這些信號彼此重疊，接收器20無法識別相關信號。Thus, it is not necessary for the wireless transmitter 10 to transmit both the illuminance signal and the on-time signal, and therefore, the illumination device can simplify the signal and can reduce power consumption. Moreover, even in the case where the wireless transmitter 10 is installed in a large number of locations, the lighting device can significantly reduce the situation where the signals overlap each other and the receiver 20 cannot recognize the relevant signals.
此外，接收器20可以分別設定：在根據從無線發射器10發射的控制信號而開啟照明器材的情況下的開啟時間；以及在根據由設定單元所設定的開啟時間和從明亮度感測器所供應的感測信號而開啟照明器材的情況下的開啟時間。這樣，接收器20可以大幅度增強可用性。Further, the receiver 20 may separately set an on time in the case where the lighting fixture is turned on according to a control signal transmitted from the wireless transmitter 10; and in an on-time according to the setting time by the setting unit and from the brightness sensor The opening time in the case where the sensing signal is supplied and the lighting fixture is turned on. In this way, the receiver 20 can greatly enhance usability.

根據本發明的熱射線式無線發射器，緊接在內部計時器結束計數之後，由控制單元獲取由明亮度感測器所感測到的周圍環境明亮度。因此，即使在人物感測器緊接在內部計時器結束計數之後感測到有人出現時，也可以確切地開啟照明器材。According to the heat ray type wireless transmitter of the present invention, the ambient brightness sensed by the brightness sensor is acquired by the control unit immediately after the internal timer ends counting. Therefore, even when a person sensor senses that a person appears immediately after the internal timer ends counting, the lighting fixture can be turned on exactly.
此外，根據本發明的無線接收器，提供了明亮度感測器，並緊接在內部計時器結束計數之後，由明亮度感測器獲取周圍環境明亮度。因此，無線發射器10只需要發射開啟時間信號，並確切地開啟照明器材，而不必執行複雜的操作。Further, according to the wireless receiver of the present invention, a brightness sensor is provided, and the brightness of the surrounding environment is acquired by the brightness sensor immediately after the internal timer ends counting. Therefore, the wireless transmitter 10 only needs to transmit the turn-on time signal and turn on the lighting fixture exactly without having to perform complicated operations.
此外，根據本發明的無線接收器不僅提供了明亮度感測器，還提供了諸如手動開關之類的設定單元，該設定單元用於設定開啟照明器材的開啟時間。此外，緊接在內部計時器結束計數之後，由明亮度感測器獲取周圍環境明亮度。因此，不必由無線發射器10發射照度信號和開啟時間信號二者，可以在簡化信號和降低功耗的狀態下，確切地開啟照明器材。Further, the wireless receiver according to the present invention not only provides a brightness sensor, but also provides a setting unit such as a manual switch for setting an opening time for turning on the lighting fixture. In addition, the brightness of the surrounding environment is acquired by the brightness sensor immediately after the internal timer ends counting. Therefore, it is not necessary to transmit both the illuminance signal and the turn-on time signal by the wireless transmitter 10, and the lighting fixture can be turned on exactly in a state where the signal is simplified and power consumption is reduced.
