The microcontroller 12 is used to control the operation of various components in the infrared sensing device 100. The driving module 13 includes a driving motor 131 and a transmission gear 132 connected to the driving motor 131 in this embodiment.

所述偵測裝置2包含有固設於電路板11的一紅外線感測器21、套設於紅外線感測器21外緣的一軸承22、裝設於上述軸承22的一轉盤23、裝設於上述轉盤23的一定位件24、及電性連接於上述控制裝置1的一基準判斷件25。 The detecting device 2 includes an infrared sensor 21 fixed on the circuit board 11, a bearing 22 sleeved on the outer edge of the infrared sensor 21, a turntable 23 mounted on the bearing 22, and a mounting device A positioning member 24 of the turntable 23 and a reference determining member 25 electrically connected to the control device 1 are provided.

所述紅外線感測器21具有遠離上述電路板11的一檢測面211,並且紅外線感測器21電性連接於控制裝置1的微控制器12。亦即,紅外線感測器21之檢測面211所接收到的信號能夠傳送至微控制器12,以供微控制器12進行相對應之判斷。再者,所述紅外線感測器21的中心線於本實施例中定義為一軸線C,並且本實施例之紅外線感應設備100所採用的紅外線感測器21數量只需為單個,亦即,本發明的紅外線感應設備100之較佳實施態樣是排除使用兩個以上之紅外線感測器21;此外紅外線感測器21可為一焦電式紅外線感應元件,亦可為一熱像感測元件,可依偵測精準需求斟酌實施。 The infrared sensor 21 has a detecting surface 211 away from the circuit board 11 , and the infrared sensor 21 is electrically connected to the microcontroller 12 of the control device 1 . That is, the signal received by the detecting surface 211 of the infrared sensor 21 can be transmitted to the microcontroller 12 for the microcontroller 12 to make a corresponding determination. Furthermore, the center line of the infrared sensor 21 is defined as an axis C in the embodiment, and the number of the infrared sensors 21 used in the infrared sensing device 100 of the present embodiment need only be a single, that is, The preferred embodiment of the infrared sensing device 100 of the present invention eliminates the use of two or more infrared sensors 21; the infrared sensor 21 can be a pyroelectric infrared sensing element or a thermal image sensing device. Components can be implemented according to the precise requirements of detection.

所述轉盤23具有一第一環體231、組接於第一環體231的一第二環體232、及相連於上述第二環體232的一傳動齒輪233,並且上述第一環體231與第二環體232的外徑大致相同,而上述傳動齒輪233的外徑小於第二環體232的外徑。其中,所述轉盤23的傳動齒輪233內緣套設於軸承22外緣,並且傳動齒輪233的中心與第二環體232的中心皆座落於上述軸線C。再者,所述傳動齒輪233嚙合於驅動模組13的驅動齒輪132,藉以使轉盤23能經由驅動模組13之驅動,而以上述軸線C為軸心自體旋轉。 The turntable 23 has a first ring body 231, a second ring body 232 connected to the first ring body 231, and a transmission gear 233 connected to the second ring body 232, and the first ring body 231. The outer diameter of the second ring body 232 is substantially the same, and the outer diameter of the transmission gear 233 is smaller than the outer diameter of the second ring body 232. The inner edge of the transmission gear 233 of the turntable 23 is sleeved on the outer edge of the bearing 22, and the center of the transmission gear 233 and the center of the second ring body 232 are seated on the axis C. Furthermore, the transmission gear 233 is meshed with the drive gear 132 of the drive module 13 so that the turntable 23 can be driven by the drive module 13 to rotate automatically with the axis C as the axis.

如圖4和圖5,所述定位件24為大致呈半球狀之殼體,定位件24裝設於轉盤23的第一環體231與第二環體232之間,並且突伸出上述轉盤23,藉以使驅動模組13驅動轉盤23旋轉時,定 位件24能隨同轉盤23以上述軸線C為軸心而自體旋轉。進一步地說,所述定位件24的外表面為圓滑狀,而定位件24之內表面形成有一目標定位部241與數個聚光部242。其中,上述目標定位部241的構造相異於任一聚光部242之構造,並且任一聚光部242可為半透光或不透光,其於本實施例中是以單個凸透鏡構造呈現,而目標定位部241於本實施例中則是以數個半凸透鏡構造及遮蔽構造之組合呈現,本發明之定位件24之所以設計呈半球狀之殼體,係為使其偵測區域能趨近二分之一之任意空間,換言之,使本發明之紅外線感應設備100設置於立方空間內之一壁面,即可偵測到整個立方空間內的狀態。 As shown in FIG. 4 and FIG. 5, the positioning member 24 is a substantially hemispherical housing. The positioning member 24 is disposed between the first ring body 231 and the second ring body 232 of the turntable 23, and protrudes from the turntable. 23, whereby the drive module 13 drives the turntable 23 to rotate, The position member 24 can be self-rotating with the turntable 23 with the above-mentioned axis C as the axis. Further, the outer surface of the positioning member 24 is rounded, and the inner surface of the positioning member 24 is formed with a target positioning portion 241 and a plurality of light collecting portions 242. The configuration of the target positioning portion 241 is different from the configuration of any of the light collecting portions 242, and any of the light collecting portions 242 may be semi-transmissive or opaque, which is presented in a single convex lens configuration in this embodiment. In the present embodiment, the target positioning unit 241 is represented by a combination of a plurality of semi-convex lens structures and a shielding structure. The positioning member 24 of the present invention is designed as a hemispherical housing for enabling the detection area. Approaching one-half of any space, in other words, by providing the infrared sensing device 100 of the present invention on one of the walls of the cubic space, the state within the entire cubic space can be detected.

再者,所述該些聚光部242與目標定位部241具有共同的一焦點,該焦點大致位於軸線C上,並且該焦點落於紅外線感測器21的檢測面211上。據此,透過目標定位部241的構造相異於任一聚光部242之構造,能夠使紅外線信號經由目標定位部241而傳遞至紅外線感測器21之檢測面211所產生的信號強度,其小於外部熱源200所發出之紅外線信號經由任一聚光部242而傳遞至紅外線感測器21之檢測面211所產生的信號強度。 Moreover, the concentrating portions 242 and the target positioning portion 241 have a common focus, the focus is substantially on the axis C, and the focus falls on the detecting surface 211 of the infrared sensor 21. Accordingly, the structure of the transmission target locating portion 241 is different from the configuration of any of the condensing portions 242, so that the infrared signal can be transmitted to the signal intensity generated by the detection surface 211 of the infrared ray sensor 21 via the target positioning portion 241. The infrared signal emitted by the infrared heat source 200 is transmitted to the detection surface 211 of the infrared sensor 21 via any of the light collecting portions 242.

進一步地說,由於任一聚光部242於本實施例中是以單個凸透鏡構造呈現,而目標定位部241於本實施例中則是以數個半凸透鏡構造及遮蔽構造之組合呈現;所以當紅外線信號經由目標定位部241而傳遞至紅外線感測器21之檢測面211時,其所產生的信號強度大致為紅外線信號經由任一聚光部242而傳遞至紅外線感測器21檢測面211所產生的信號強度之一半。 Further, since any concentrating portion 242 is presented in a single convex lens configuration in the present embodiment, the target positioning portion 241 is represented by a combination of a plurality of semi-convex lens structures and a shielding structure in this embodiment; When the infrared signal is transmitted to the detection surface 211 of the infrared sensor 21 via the target positioning unit 241, the signal intensity generated by the infrared signal is substantially transmitted to the detection surface 211 of the infrared sensor 21 via the light collection unit 242. One and a half of the resulting signal strength.

依上所述,由於所述定位件24為半球狀之構造,以使紅外線感測器21的檢測面211能夠以設置於定位件24焦點上之方式,令紅外線感應設備100外部之紅外線信號經由半球狀定位件24而聚焦於紅外線感測器21檢測面211,藉以透過半球狀定位件24達到提升信號接收範圍之效果。也就是說,半球狀定位件24能夠將 自任何位置傳遞至其上的紅外線信號聚集在紅外線感測器21,以使紅外線感測器21透過半球狀定位件24之設置而具備有較廣之信號接收範圍。 According to the above, since the positioning member 24 has a hemispherical structure, so that the detecting surface 211 of the infrared sensor 21 can be disposed on the focus of the positioning member 24, the infrared signal outside the infrared sensing device 100 is passed through The hemispherical positioning member 24 is focused on the detecting surface 211 of the infrared sensor 21, thereby achieving the effect of raising the signal receiving range through the hemispherical positioning member 24. That is, the hemispherical positioning member 24 can The infrared signal transmitted thereto from any position is collected in the infrared sensor 21 so that the infrared sensor 21 is provided with a wider signal receiving range through the arrangement of the hemispherical positioning member 24.

此外,所述定位件24於本實施例中是以凸透鏡型式達到聚焦於紅外線感測器21檢測面211之效果,但於實際應用時,定位件24的構造並不以此為限。舉例來說,定位件24亦得以圖式所未呈現的反射鏡型式或菲涅耳鏡(Fresnel’s lens)型式達到聚焦於紅外線感測器21之檢測面211的效果。 In addition, in the embodiment, the positioning member 24 achieves the effect of focusing on the detecting surface 211 of the infrared sensor 21 in a convex lens type. However, in actual application, the configuration of the positioning member 24 is not limited thereto. For example, the positioning member 24 can also achieve the effect of focusing on the detecting surface 211 of the infrared sensor 21 by a mirror type or a Fresnel's lens type not shown.

如圖6,所述基準判斷件25是用以偵測定位件24之目標定位部241旋轉一圈所需的時間,並將該時間定義為一單位時段(Tc)。換言之,基準判斷件25的作用在於提供定位件24旋轉的起始時間點之參考基準。而基準判斷件25於本實施例中是包含有安裝在電路板11且電性連接於微控制器12的一光接收器251。所述轉盤23的第二環體232上設有對應於目標定位部241的一基準件27,於本實施例中是一反光片271,並且當反光片271面向光接受器251時,光接收器251適於接收自反光片271反射之光信號。因此,當反光片271(目標定位部241)對位於光接收器251之後,轉盤23旋轉一圈而使光接受器251收到來自反光片271的光信號時,微控制器12經由光接受器251所傳輸之信號,即能得知轉盤23(或目標定位部241)旋轉一圈所需的單位時段(Tc)。 As shown in FIG. 6, the reference judging member 25 is for detecting the time required for the target positioning portion 241 of the positioning member 24 to rotate one turn, and defines the time as a unit time period (Tc). In other words, the function of the reference judging member 25 is to provide a reference datum of the starting point of time at which the positioning member 24 is rotated. The reference judging component 25 includes a photoreceiver 251 mounted on the circuit board 11 and electrically connected to the microcontroller 12 in this embodiment. A reference member 27 corresponding to the target positioning portion 241 is disposed on the second ring body 232 of the turntable 23, which is a light reflecting sheet 271 in this embodiment, and light receiving when the light reflecting sheet 271 faces the light receiver 251. The 251 is adapted to receive an optical signal reflected from the retroreflective sheeting 271. Therefore, when the reflector 271 (the target positioning portion 241) is positioned behind the light receiver 251, the turntable 23 rotates one turn and the light receiver 251 receives the light signal from the retroreflective sheet 271, the microcontroller 12 passes the light receiver. The signal transmitted by 251 can know the unit time period (Tc) required for the turntable 23 (or the target positioning portion 241) to rotate one turn.

此外,本實施例中是以反光片271作為基準件27,並搭配作為基準判斷件25的光接收器251,以達到提供定位件24旋轉起始參考時間點之參考基準效果,但於實際應用時,基準判斷件25並不以光接收器251為限。舉例來說,所述基準判斷件25亦可使用微動開關搭配設置於第二環體232上的”凸點結構”(即凸點結構作為基準件27),以提供定位件24旋轉起始參考時間點(圖略);或為光遮斷器搭配設置於第二環體232上的”遮斷結構”(即遮斷結 構作為基準件27),以提供定位件24旋轉起始參考時間點(圖略);再者反光片271係提供定位件24旋轉起始參考時間點,亦即作為旋轉一圈中0°及360°之重疊點,故,基準件27亦可於90°、180°以及270°增設反光片271以提高校正準確度。 In addition, in the embodiment, the light reflecting sheet 271 is used as the reference member 27, and is matched with the light receiver 251 as the reference determining member 25, so as to achieve the reference reference effect of providing the reference point of rotation of the positioning member 24, but in practical application. The reference judging member 25 is not limited to the photoreceiver 251. For example, the reference judging member 25 can also use a micro switch to match the "bump structure" disposed on the second ring body 232 (ie, the bump structure as the reference member 27) to provide the rotation start reference of the positioning member 24. Time point (not shown); or for the photointerrupter with the "interrupting structure" (ie, the occlusion structure) disposed on the second ring body 232 The reference member 27) is configured to provide a rotation start start reference time point (not shown) of the positioning member 24; further, the retroreflective sheet 271 provides a rotation start start reference time point of the positioning member 24, that is, 0° in one rotation and The overlapping point of 360°, the reference member 27 can also add the retroreflective sheeting 271 at 90°, 180° and 270° to improve the correction accuracy.

以上即為本實施例之紅外線感應設備100的簡要說明,以下接著介紹本實施例之偵測熱源方位的方法,其方法如下(請參閱圖1C、圖7至圖9):提供上述之紅外線感應設備100,有關紅外線感應設備100的具體構造在此則不加以復述,當下述說明提及紅外線感應設備100的元件時,請適時參酌相對應之圖式,其包括步驟如下: The above is a brief description of the infrared sensing device 100 of the present embodiment. The following describes the method for detecting the orientation of the heat source according to the embodiment, and the method is as follows (please refer to FIG. 1C, FIG. 7 to FIG. 9): providing the above-mentioned infrared sensing The device 100, the specific configuration of the infrared sensing device 100 will not be repeated herein. When the following description refers to the components of the infrared sensing device 100, please refer to the corresponding drawings as appropriate, including the following steps:

步驟一(S110):所述控制裝置1的微控制器12命令驅動模組13運作,以驅動轉盤23及其上的定位件24(目標定位部241)進行旋轉,並於目標定位部241旋轉的過程中,透過基準判斷件25偵測出目標定位部241旋轉一圈所需的單位時段(Tc),同時記錄紅外線感應設備100之一掃描範圍S內的暫態熱源狀況。該暫態熱源狀況與預設參數所界定之環境溫度均值比對後,若無既存之外部熱源200,則紅外線感應設備100,更新暫態熱源狀況,作為後續之比對依據,並進入一備便狀態,使轉盤23及其上的定位件24(目標定位部241)停止旋轉,並將定位件24上的目標定位部241對位於基準判斷件25作為停止位置。反之,則進行步驟三之方位判斷動作。 Step 1 (S110): The microcontroller 12 of the control device 1 commands the driving module 13 to operate to drive the turntable 23 and the positioning member 24 (target positioning portion 241) thereon to rotate and rotate at the target positioning portion 241. In the process, the reference period determining unit 25 detects the unit time period (Tc) required for the target positioning unit 241 to rotate one turn, and simultaneously records the transient heat source condition in the scanning range S of one of the infrared sensing devices 100. After the transient heat source condition is compared with the ambient temperature mean value defined by the preset parameter, if there is no existing external heat source 200, the infrared sensing device 100 updates the transient heat source status as a follow-up comparison basis and enters a standby In the state, the turntable 23 and the positioning member 24 (target positioning portion 241) thereon are stopped from rotating, and the target positioning portion 241 on the positioning member 24 is positioned as the reference position determining member 25 as the stop position. Otherwise, the position determination operation of step 3 is performed.

須說明的是,當紅外線感應設備100被裝設在設有至少一出入口300的環境時(如圖1B),該出入口300可視為一外部熱源200出現點,紅外線感應設備100的掃描範圍S較佳為涵蓋上述出入口300。並且使處於備便狀態的紅外線感應設備100,其目標定位部241之遮蔽構造以非朝向上述出入口300之方式設置,藉以避 免外部熱源200自該出入口300進出時,其所發出的紅外線信號無法自遮蔽構造傳遞入紅外線感測器21,進而提升紅外線感應設備100偵測動態之外部熱源200的反應速度。 It should be noted that when the infrared sensing device 100 is installed in an environment in which at least one inlet and outlet 300 is provided (as shown in FIG. 1B ), the inlet and outlet 300 can be regarded as an external heat source 200, and the scanning range S of the infrared sensing device 100 is compared. The best includes the above-mentioned entrances and exits 300. Further, the infrared sensing device 100 in the standby state is disposed such that the shielding structure of the target positioning portion 241 is not directed toward the inlet and outlet 300, thereby avoiding When the external heat source 200 is prevented from entering and exiting the inlet and outlet 300, the infrared signal emitted from the external heat source 200 cannot be transmitted from the shielding structure to the infrared sensor 21, thereby improving the reaction speed of the infrared external sensing device 100 to detect the dynamic external heat source 200.

再者,所述紅外線感應設備100能在對應目標定位部241之遮蔽構造的殼體3部位上設置有一方向標示31,藉以便於使用者安裝紅外線感應設備100時,安排所需偵測方位之定位,亦即安排受偵測之區域與紅外線感應設備100兩者間方位之關聯,亦可藉由該方向標示31,將處於備便狀態的紅外線感應設備100之目標定位部241遮蔽構造以非朝向上述出入口之方式設置。 Furthermore, the infrared sensing device 100 can be provided with a direction indicator 31 on the portion of the housing 3 corresponding to the shielding structure of the target positioning portion 241, so as to arrange the positioning of the required detection orientation when the user installs the infrared sensing device 100. That is, the relationship between the detected area and the infrared sensing device 100 is arranged, and the target positioning portion 241 of the infrared sensing device 100 in the standby state can be shielded from the non-oriented direction by the direction indicator 31. The above-mentioned way of entrance and exit is set.

步驟二(S120):處於備便狀態的紅外線感應設備100於其掃描範圍S內持續進行熱源偵測,此時的定位件24為未旋轉之狀態。需補充說明的是,本實施例中圖式所呈現的紅外線感應設備100掃描範圍S僅為示意之用,並不局限於此。 Step 2 (S120): The infrared sensing device 100 in the standby state continues to perform heat source detection in the scanning range S, and the positioning member 24 at this time is in an unrotated state. It should be noted that the scanning range S of the infrared sensing device 100 presented in the drawing in this embodiment is for illustrative purposes only and is not limited thereto.

步驟三(S130):當紅外線感應設備100偵測到一外部熱源200(如:人)進入其掃描範圍S內時(如圖7),實施一方位判斷動作,並且所述控制裝置1可選擇性地發出一電性訊號,以控制一外部裝置(例如:警報裝置或散熱裝置)。實際應用上,紅外線感應設備100亦可於偵測出外部熱源200(如:人)進入掃描範圍S內時,進行環境溫度之偵測比對,當環境溫度高於30℃時,使掃描範圍S內之散熱裝置(圖略)進入備便狀態。 Step 3 (S130): When the infrared sensing device 100 detects that an external heat source 200 (eg, a person) enters its scanning range S (as shown in FIG. 7), an orientation determination action is performed, and the control device 1 can select An electrical signal is sent to control an external device (for example, an alarm device or a heat sink). In practical applications, the infrared sensing device 100 can also detect the ambient temperature when the external heat source 200 (eg, a person) enters the scanning range S, and when the ambient temperature is higher than 30 ° C, the scanning range is made. The heat sink (slightly shown) in S enters the standby state.

其中,本實施例中判斷外部熱源200是否進入掃描範圍S的方式,是透過紅外線感測器21所收到的信號強度來判斷。進一步地說,當紅外線感測器21所收到的信號強度分布異於步驟一(S110)中所更新的暫態熱源狀況時,微控制器即判斷為外部熱源200進入紅外線感應設備100的掃描範圍S。 The manner in which the external heat source 200 enters the scanning range S is determined in the present embodiment is determined by the signal strength received by the infrared sensor 21. Further, when the signal intensity distribution received by the infrared sensor 21 is different from the transient heat source status updated in the first step (S110), the microcontroller determines that the external heat source 200 enters the scanning of the infrared sensing device 100. Range S.

再者,上述方位判斷動作包含:所述控制裝置1的微控制器 12命令驅動模組13運作,以驅動轉盤23及其上的定位件24(目標定位部241)進行旋轉(如圖8和圖9)。而在目標定位部241旋轉的過程中,控制上述目標定位部241的旋轉速度小於紅外線感測器21的信號接收頻率,以避免紅外線感應器21來不及反應而造成定位偏移或訊號振幅不足的情形。於本實施例中,控制裝置1是控制所述目標定位部241每轉一圈需20秒,但不以此為限。其中,當控制裝置1驅動定位件24進行旋轉時,外部熱源200所發出之紅外線信號經由目標定位部241而傳遞至紅外線感測器21之檢測面211所產生的信號強度,其小於外部熱源200所發出之紅外線信號經由任一聚光部242而傳遞至紅外線感測器21之檢測面211所產生的信號強度。 Furthermore, the orientation determining operation includes: the microcontroller of the control device 1 The command drive module 13 operates to drive the turntable 23 and the positioning member 24 (target positioning portion 241) thereon to rotate (see Figs. 8 and 9). During the rotation of the target positioning unit 241, the rotation speed of the target positioning unit 241 is controlled to be smaller than the signal receiving frequency of the infrared sensor 21, so as to prevent the infrared sensor 21 from reacting to cause a positioning offset or insufficient signal amplitude. . In this embodiment, the control device 1 controls the target positioning unit 241 to take one rotation per turn, but is not limited thereto. When the control device 1 drives the positioning member 24 to rotate, the infrared signal emitted by the external heat source 200 is transmitted to the detection surface 211 of the infrared sensor 21 via the target positioning portion 241, which is smaller than the external heat source 200. The emitted infrared signal is transmitted to the signal intensity generated by the detection surface 211 of the infrared sensor 21 via any of the light collecting portions 242.

所述方位判斷動作接著進行下述之外部熱源200方位判斷:以所述軸線C為法線的一平面(如:地面)定義為一方位面P,而在以軸線C為中心的方位面P上,基準判斷件25對應於方位面P的位置定義為一基準方位(0°)。 The orientation determining operation then performs the following orientation determination of the external heat source 200: a plane (eg, ground) with the axis C as a normal is defined as an azimuth plane P, and an azimuth plane P centered on the axis C The position of the reference judging member 25 corresponding to the azimuth plane P is defined as a reference orientation (0°).

自外部熱源200所發出之紅外線信號經由目標定位部241而傳遞至紅外線感測器21之檢測面211時,其對應於單位時段(Tc)的一時間點定義為一熱源時間點(Ts)。也就是說,在熱源時間點之前,外部熱源200所發出之紅外線信號並未經由目標定位部241而傳遞至紅外線感測器21之檢測面211。 When the infrared signal emitted from the external heat source 200 is transmitted to the detecting surface 211 of the infrared sensor 21 via the target positioning portion 241, a time point corresponding to the unit period (Tc) is defined as a heat source time point (Ts). That is to say, the infrared signal emitted from the external heat source 200 is not transmitted to the detecting surface 211 of the infrared sensor 21 via the target positioning portion 241 before the heat source time point.

其中,當外部熱源200於熱源時間點時,目標定位部241正投影於方位面P的位置,其相對於基準方位的角度定義為一熱源方位角θ x,並且熱源方位角θ x經由控制裝置1之微控制器12運算下述方程式而得知:θ x=(Ts/Tc)x 360°。再者,當得知上述熱源方位角θ x時,所述控制裝置1可選擇性地發出一電性訊號,以控制所述外部裝置。而實際應用上,紅外線感應設備100可於偵測出外部熱源200(如:人)處於某一方位時間超過一設定值 時,啟動該方位之散熱裝置。 Wherein, when the external heat source 200 is at the heat source time point, the target positioning portion 241 is projected on the position of the azimuth plane P, the angle with respect to the reference azimuth is defined as a heat source azimuth angle θ x , and the heat source azimuth angle θ x is controlled via the control device The microcontroller 12 of 1 calculates the following equation: θ x = (Ts / Tc) x 360 °. Furthermore, when the heat source azimuth angle θ x is known, the control device 1 can selectively emit an electrical signal to control the external device. In practical applications, the infrared sensing device 100 can detect that the external heat source 200 (eg, a person) is in a certain orientation time and exceeds a set value. When the heat sink of the orientation is activated.

步驟四(S140):當外部熱源200離開掃描範圍S後,更新暫態熱源狀況,並使所述紅外線感應設備100進入備便狀態;使轉盤23及其上的定位件24(目標定位部241)停止旋轉,並將定位件24上的目標定位部241對位於基準判斷件25。再者,當外部熱源200離開掃描範圍S後,控制裝置1可選擇性地發出一電性訊號,以控制所述外部裝置。而實際應用上,紅外線感應設備100可於偵測出外部熱源200(如:人)離開掃描範圍S後,關閉掃描範圍S內之散熱裝置。 Step 4 (S140): After the external heat source 200 leaves the scanning range S, the transient heat source condition is updated, and the infrared sensing device 100 enters the standby state; the turntable 23 and the positioning member 24 thereon (the target positioning portion 241) The rotation is stopped, and the target positioning portion 241 on the positioning member 24 is positioned on the reference judging member 25. Moreover, after the external heat source 200 leaves the scanning range S, the control device 1 can selectively emit an electrical signal to control the external device. In practical applications, the infrared sensing device 100 can turn off the heat sink in the scanning range S after detecting that the external heat source 200 (eg, a person) leaves the scanning range S.

其中,本實施例判斷外部熱源200是否已離開掃描範圍S的方式,是透過紅外線感測器21所收到的信號強度來判斷。進一步地說,當紅外線感測器21所收到的信號強度分布等同於紅外線感測器21在步驟一(S110)中所更新的暫態熱源狀況時,微控制器12即判斷為外部熱源200已離開紅外線感應設備100的掃描範圍S。 The manner in which the present embodiment determines whether the external heat source 200 has left the scanning range S is determined by the signal strength received by the infrared sensor 21. Further, when the signal intensity distribution received by the infrared sensor 21 is equal to the transient heat source condition updated by the infrared sensor 21 in step one (S110), the microcontroller 12 determines that the external heat source 200 is The scanning range S of the infrared sensing device 100 has been left.

藉此,本發明實施例所提供之紅外線感應設備100及其偵測熱源方位的方法,其有效地利用紅外線信號經由目標定位部241而傳遞至紅外線感測器21所產生的信號強度異於經由目標定位部241以外的定位件24部位(如:聚光部242)而傳遞至紅外線感測器21所產生的信號強度、及紅外線感應設備100之基準判斷件25與目標定位部241之配合,以使所述外部熱源200於特定時間點(即熱源時間點)所在的熱源方位角θ x能夠被迅速地測得。 Therefore, the infrared sensing device 100 and the method for detecting the orientation of the heat source provided by the embodiment of the present invention effectively transmit the signal intensity generated by the infrared signal to the infrared sensor 21 via the target positioning portion 241 through the infrared signal. The signal intensity generated by the position of the positioning member 24 other than the target positioning unit 241 (for example, the condensing unit 242) is transmitted to the infrared sensor 21, and the reference determining unit 25 of the infrared sensing device 100 is matched with the target positioning unit 241. The heat source azimuth angle θ x at which the external heat source 200 is located at a specific point in time (ie, the heat source time point) can be quickly measured.

再者,由於判斷外部熱源200進入或離開紅外線感應設備100掃描範圍S的方式,是透過單個紅外線感測器21在步驟一(S110)中所更新的暫態熱源狀況為基準,所以只要紅外線感應設備100掃描範圍S內存在外部熱源,即能夠被探知。據此,所述紅外線 感應設備100及其偵測熱源方位的方法是能夠針對靜態或是動態的外部熱源200進行熱源方位角θ x之偵測。 Furthermore, since the manner in which the external heat source 200 enters or leaves the scanning range S of the infrared sensing device 100 is determined, the transient heat source status updated in the first step (S110) by the single infrared sensor 21 is used as a reference, so that infrared sensing is required. The device 100 has an external heat source within the scanning range S, that is, can be detected. According to this, the infrared rays The sensing device 100 and its method of detecting the orientation of the heat source are capable of detecting the heat source azimuth angle θ x for the static or dynamic external heat source 200.

此外,步驟一至步驟四中,該目標定位部241在被驅動旋轉後,亦可將其設定為維持旋轉之狀態直至斷電或關閉,亦即紅外線感應設備100處於備便狀態時,仍使轉盤23及其上的定位件24(目標定位部241)旋轉,以增加偵測外部熱源200反應速度並維持最為即時之暫態熱源狀況。 In addition, in steps 1 to 4, after the target positioning unit 241 is driven to rotate, it can also be set to maintain the state of rotation until the power is turned off or turned off, that is, when the infrared sensing device 100 is in the standby state, the turntable is still enabled. 23 and the positioning member 24 (target positioning portion 241) thereon rotate to increase the reaction speed of the external heat source 200 and maintain the most instantaneous transient heat source condition.

需補充說明的是,上述各步驟中並未具體限定所述單位時段(Tc)的時間單位,也就是說,單位時段(Tc)的時間單位可以依設計者需求而加以調整。舉例而言,在步驟一(S110)中,可將透過基準判斷件25偵測目標定位部241旋轉一圈時,所需耗費的總秒數定義為該單位時段,並且單位時段為M秒;而在方位判斷動作中,熱源時間點為第N秒,並且M大於等於N,方程式則進一步限定為:θ x=(N/M)x 360°。或者,在步驟一(S110)中,可將透過基準判斷件25偵測目標定位部241旋轉一圈時,經由目標定位部241而傳遞至紅外線感測器21的時脈總數定義為該單位時段,並且單位時段為R個時脈;而在方位判斷動作中,熱源時間點為第Q個時脈,R與Q皆為正整數,且R大於等於Q,該方程式進一步限定為:θ x=(Q/R)x 360°。 It should be added that the time unit of the unit time period (Tc) is not specifically limited in the above steps, that is, the time unit of the unit time period (Tc) can be adjusted according to the designer's needs. For example, in step 1 (S110), when the detection target determining unit 241 is rotated by one rotation through the reference determining unit 25, the total number of seconds required to be used is defined as the unit time period, and the unit time period is M seconds; In the position determining operation, the heat source time point is the Nth second, and M is greater than or equal to N, and the equation is further defined as: θ x=(N/M) x 360°. Alternatively, in step 1 (S110), when the detection target determining unit 241 detects one rotation of the target positioning unit 241, the total number of clocks transmitted to the infrared sensor 21 via the target positioning unit 241 is defined as the unit time period. And the unit time period is R clocks; and in the position determining operation, the heat source time point is the Qth clock, R and Q are both positive integers, and R is greater than or equal to Q, the equation is further defined as: θ x= (Q/R) x 360°.

此外,本實施例所描述的紅外線感應設備100之構造僅作為理解本發明偵測熱源方位的方法之用,亦即,於符合本發明偵測熱源方位的方法之前提下,紅外線感應設備100的構造能夠依據設計者需求而加以調整,並不侷限本發明所提出之偵測熱源方位的方法。 In addition, the structure of the infrared sensing device 100 described in this embodiment is only used to understand the method for detecting the heat source orientation of the present invention, that is, before the method for detecting the heat source orientation according to the present invention, the infrared sensing device 100 is The configuration can be adjusted according to the designer's needs, and is not limited to the method of detecting the heat source orientation proposed by the present invention.

[第二實施例] [Second embodiment]

請參閱圖10,其為本發明的第二實施例,本實施例大致與第 一實施例類似,相同處則不再贅述,而兩者的差異主要在於偵測裝置2的定位件24,具體差異說明如下。 Please refer to FIG. 10 , which is a second embodiment of the present invention. An embodiment is similar, and the same point is not described again, and the difference between the two is mainly in the positioning member 24 of the detecting device 2, and the specific differences are explained below.

本實施例定位件24的內表面形成有目標定位部241及圍繞於目標定位部241的一環繞部243。其中,目標定位部241的構造異於環繞部243之構造,並能使紅外線信號經由目標定位部241而傳遞至紅外線感測器21所產生的信號強度,其大於紅外線信號經由環繞部243而傳遞至紅外線感測器21所產生的信號強度。 The inner surface of the positioning member 24 of the present embodiment is formed with a target positioning portion 241 and a surrounding portion 243 surrounding the target positioning portion 241. The structure of the target positioning unit 241 is different from the structure of the surrounding portion 243, and the infrared signal can be transmitted to the signal intensity generated by the infrared sensor 21 via the target positioning unit 241, which is greater than the infrared signal transmitted through the surrounding portion 243. The signal intensity generated by the infrared sensor 21.

進一步地說,所述目標定位部241可為半透光或不透光,其於本實施例中是以數個半凸透鏡構造及遮蔽構造之組合呈現,而環繞部243於本實施例中則包含有一C型的聚光環繞部2431及位於上述聚光環繞部2431內的一遮蔽環繞部2432。其中,所述聚光環繞部2431的兩末端相連於目標定位部241的最外端,亦即,聚光環繞部2431為定位件24中的最外圈凸透鏡構造,藉以作為偵測外部熱源200出現與否之偵測。再者,所述目標定位部241具有一焦點,並且該焦點落於紅外線感測器21的檢測面211上。 Further, the target positioning portion 241 may be semi-transmissive or opaque, which in the present embodiment is represented by a combination of a plurality of semi-convex lens structures and a shielding structure, and the surrounding portion 243 is in this embodiment. The C-shaped concentrating surrounding portion 2431 and a shielding surrounding portion 2432 located in the concentrating surrounding portion 2431 are included. The two ends of the concentrating surrounding portion 2431 are connected to the outermost end of the target positioning portion 241, that is, the concentrating surrounding portion 2431 is the outermost convex lens structure in the positioning member 24, thereby detecting the external heat source 200. Detection of presence or absence. Furthermore, the target positioning portion 241 has a focus, and the focus falls on the detection surface 211 of the infrared sensor 21.

而於步驟三(S130)中,當控制裝置1驅動定位件24進行旋轉時,外部熱源200所發出之紅外線信號經由目標定位部241而傳遞至紅外線感測器21所產生的信號強度,其異於外部熱源200所發出之紅外線信號經由環繞部243而傳遞至紅外線感測器21所產生的信號強度。更進一步地說,於本實施例中,外部熱源200所發出之紅外線信號僅能經由目標定位部241或聚光環繞部2431而傳遞至紅外線感測器21,而無法經由遮蔽環繞部2432而傳遞至紅外線感測器21。而實際應用上,紅外線感應設備100是以本實施例之定位件24,來進行熱源方位偵測,當控制裝置1驅動定位件24進行旋轉時,只需將紀錄旋轉一圈之完整訊號波型,核定單位時段(Tc)相對之波型區段中振幅最高處,視為一熱源時間點(Ts),即可推算熱源方位。 In step 3 (S130), when the control device 1 drives the positioning member 24 to rotate, the infrared signal emitted by the external heat source 200 is transmitted to the signal intensity generated by the infrared sensor 21 via the target positioning portion 241, and the difference is different. The infrared signal emitted from the external heat source 200 is transmitted to the signal intensity generated by the infrared sensor 21 via the surrounding portion 243. Furthermore, in the present embodiment, the infrared signal emitted by the external heat source 200 can only be transmitted to the infrared sensor 21 via the target positioning portion 241 or the light collecting surrounding portion 2431, and cannot be transmitted through the shielding surrounding portion 2432. To the infrared sensor 21. In practical applications, the infrared sensing device 100 uses the positioning member 24 of the embodiment to perform heat source orientation detection. When the control device 1 drives the positioning member 24 to rotate, the complete signal waveform of only one rotation of the record is required. The approved unit time period (Tc) is the highest amplitude in the waveform section, and is regarded as a heat source time point (Ts), so that the heat source orientation can be estimated.

[第三實施例] [Third embodiment]

請參閱圖11和圖12,其為本發明的第三實施例,本實施例大致與第二實施例類似,相同處則不再贅述,而兩者的差異主要在於偵測裝置2的定位件24,並且本實施例進一步包含有對應於定位件24的一聚焦件26,具體差異說明如下。 Referring to FIG. 11 and FIG. 12, which is a third embodiment of the present invention, the present embodiment is substantially similar to the second embodiment, and the same portions are not described again, and the difference between the two is mainly the positioning device of the detecting device 2. 24, and this embodiment further includes a focusing member 26 corresponding to the positioning member 24, the specific differences are explained below.

所述聚焦件26安裝於殼體3並且罩設於定位件24外,聚焦件26形成有數個聚光部261,而定位件24形成有目標定位部241及圍繞於目標定位部241的一環繞部243。其中,任一聚光部261於本實施例中是以單個凸透鏡構造呈現,而目標定位部241的構造異於環繞部243之構造,並能使紅外線信號經由任一聚光部261與目標定位部241而傳遞至紅外線感測器21所產生的信號強度,其小於外部熱源200所發出之紅外線信號經由任一聚光部261與環繞部243而傳遞至紅外線感測器21所產生的信號強度。 The focusing member 26 is mounted on the housing 3 and is disposed outside the positioning member 24 . The focusing member 26 is formed with a plurality of collecting portions 261 , and the positioning member 24 is formed with the target positioning portion 241 and a surrounding around the target positioning portion 241 . Department 243. In any of the embodiments, the concentrating portion 261 is represented by a single convex lens structure, and the configuration of the target positioning portion 241 is different from the configuration of the surrounding portion 243, and enables the infrared signal to be positioned through the concentrating portion 261 and the target. The signal intensity generated by the portion 241 transmitted to the infrared sensor 21 is smaller than the signal intensity generated by the infrared signal emitted from the external heat source 200 transmitted to the infrared sensor 21 via any of the light collecting portion 261 and the surrounding portion 243. .

進一步地說,所述目標定位部241可為半透光或不透光,其於本實施例中是以半凸透光構造呈現,亦即,目標定位部241會遮蔽上述聚光部261的半個凸透鏡構造,而環繞部243於本實施例中則是以透光構造呈現。再者,該些聚光部242具有共同的一焦點,該焦點落於紅外線感測器21上。 Further, the target positioning portion 241 may be semi-transparent or opaque, which is presented in a semi-convex light transmissive structure in this embodiment, that is, the target positioning portion 241 shields the concentrating portion 261. The semi-convex lens configuration, while the surrounding portion 243 is present in the light transmissive configuration in this embodiment. Moreover, the concentrating portions 242 have a common focus which falls on the infrared sensor 21.

而於步驟三(S130)中,當控制裝置1驅動定位件24進行旋轉時,聚焦件26保持不動,而外部熱源200所發出之紅外線信號經由任一聚光部261與目標定位部241而傳遞至紅外線感測器21所產生的信號強度,其小於外部熱源200所發出之紅外線信號經由任一聚光部261與環繞部243而傳遞至紅外線感測器21所產生的信號強度。更進一步地說,於本實施例中,外部熱源200所發出之紅外線信號穿過聚焦件26的任一聚光部261後,當經過目標定位部241時會有一半的信號被遮蔽,但經過環繞部243時會直接穿過,因而使得信號強度不同。 In step 3 (S130), when the control device 1 drives the positioning member 24 to rotate, the focusing member 26 remains stationary, and the infrared signal emitted by the external heat source 200 is transmitted to the target positioning portion 241 via any of the collecting portion 261. The signal intensity generated by the infrared ray sensor 21 is smaller than the signal intensity generated by the infrared ray signal emitted from the external heat source 200 via the concentrating portion 261 and the surrounding portion 243 to the infrared ray sensor 21. Further, in the present embodiment, after the infrared signal emitted by the external heat source 200 passes through any of the concentrating portions 261 of the focusing member 26, half of the signals are blocked when passing through the target positioning portion 241, but after passing through The surrounding portion 243 passes directly through, thus making the signal strength different.

據此,本實施例所提供的紅外線感應設備100之最大優點在 於固定住聚焦件26,使紅外線感測器21所接收之紅外線訊號更為穩定。 Accordingly, the greatest advantage of the infrared sensing device 100 provided by the embodiment is The focusing member 26 is fixed to make the infrared signal received by the infrared sensor 21 more stable.

[第四實施例] [Fourth embodiment]

請參閱圖13,其為本發明的第四實施例,本實施例大致與第三實施例類似,相同處則不再贅述,而兩者的差異主要在於本實施例的目標定位部241是以鏤空或完全透光構造呈現,而環繞部243則是以半透光構造呈現。 Referring to FIG. 13 , which is a fourth embodiment of the present invention, the present embodiment is substantially similar to the third embodiment, and the same portions are not described again, and the difference between the two is mainly that the target positioning unit 241 of the present embodiment is The hollowed out or fully light transmissive structure is presented, while the surrounding portion 243 is presented in a semi-transmissive configuration.

進一步地說,透過目標定位部241以鏤空或完全透光構造呈現,可使穿透任一聚光部261與目標定位部241之紅外線訊號,完全聚焦傳遞於紅外線感測器21上。再者,透過環繞部243以半透光構造呈現,可使所述外部熱源200所發出之紅外線信號經由聚光部261與目標定位部241而傳遞至紅外線感測器21所產生的信號強度,遠大於外部熱源200所發出之紅外線信號經由任一聚光部261與環繞部243而傳遞至紅外線感測器21所產生的信號強度。 Further, the target positioning portion 241 is configured to be hollowed out or completely transparent, so that the infrared signal passing through any of the concentrating portion 261 and the target positioning portion 241 can be completely focused and transmitted to the infrared ray sensor 21. Furthermore, the surrounding portion 243 is provided in a semi-transmissive structure, and the infrared signal emitted by the external heat source 200 can be transmitted to the signal intensity generated by the infrared sensor 21 via the concentrating portion 261 and the target positioning portion 241. It is much larger than the signal intensity generated by the infrared signal emitted by the external heat source 200 to the infrared sensor 21 via any of the concentrating portion 261 and the surrounding portion 243.

因此,本實施例在實際應用上,當有外部熱源200進入掃描範圍S時,紅外線信號經由聚焦件26與環繞部243而傳遞至紅外線感測器21的信號強度較小,但控制裝置1仍可辨識判斷,進而驅動定位件24進行旋轉,並利用目標定位部241來追蹤外部熱源200。 Therefore, in the practical application, when the external heat source 200 enters the scanning range S, the signal intensity transmitted by the infrared signal to the infrared sensor 21 via the focusing member 26 and the surrounding portion 243 is small, but the control device 1 remains The determination can be recognized, and the positioning member 24 is driven to rotate, and the external heat source 200 is tracked by the target positioning portion 241.

本實施例最大之優點在於:紅外線感應設備100可精準判斷多重外部熱源200之方位,或是進一步偵測出外部熱源200的強度。進一步地說,紅外線感應設備100可針對外部熱源200靜止與移動的狀態來加以界定外部熱源200之方位,或是利用紅外線信號之振幅大小來界定外部熱源200之強度。 The biggest advantage of this embodiment is that the infrared sensing device 100 can accurately determine the orientation of the multiple external heat sources 200 or further detect the intensity of the external heat source 200. Further, the infrared sensing device 100 can define the orientation of the external heat source 200 for the state of the external heat source 200 being stationary and moving, or use the amplitude of the infrared signal to define the intensity of the external heat source 200.

前述各實施例中,紅外線信號均須透過定位件24傳遞至紅外 線感測器21,其中定位件24又設有目標定位部241,作為定位追蹤外部熱源200之用。而定位件24上除了目標定位部241外,還可設有環繞部243(第三、第四實施例)、聚光環繞部2431(第二實施例)、或是聚光部242(第一實施例),藉以將上述進入或已存在於掃描範圍S時之外部熱源200所發出的紅外線信號,傳遞給紅外線感測器21,進而啟動步驟三(S130)之方位判斷動作。在實際使用上,可於殼體3上另增設一個與控制裝置1電性連接之偵測元件32,藉以實現偵測角度或偵測條件的需求,並達到避免誤判及可更為精準地偵測到外部熱源200是否進入掃描範圍S。而上述偵測元件32之感測媒介可為紅外線、超音波、或可見光,在此不加以限制。 In the foregoing embodiments, the infrared signals must be transmitted to the infrared through the positioning member 24. The line sensor 21, wherein the positioning member 24 is further provided with a target positioning portion 241 for positioning and tracking the external heat source 200.

In actual use, a detecting component 32 electrically connected to the control device 1 can be additionally added to the housing 3 to realize the requirement of detecting angle or detecting conditions, and avoiding misjudgment and more accurate detection. It is detected whether the external heat source 200 enters the scanning range S. The sensing medium of the detecting component 32 may be infrared, ultrasonic, or visible light, which is not limited herein.

請參閱圖14,其為本發明的第五實施例,本實施例大致與第三實施例類似,相同處則不再贅述,而兩者的差異主要在於本實施例的定位件24的結構設計。 Referring to FIG. 14 , which is a fifth embodiment of the present invention, the present embodiment is substantially similar to the third embodiment, and the same portions are not described again, and the difference between the two is mainly due to the structural design of the positioning member 24 of the present embodiment. .

具體來說,本實施例的定位件24具有一目標定位部241及數個圍繞於目標定位部241的聚光部242,上述目標定位部241是以數個相鄰排列的凸透鏡構造呈現,而每個聚光部242是以單個凸透鏡構造呈現。再者,每個聚光部242的尺寸小於目標定位部241中任一個凸透鏡尺寸,該些聚光部242圍繞於目標定位部241而排列成數個相疊的C型態樣,並且上述C型態樣的數量大於目標定位部241所包含的凸透鏡構造數量。 Specifically, the positioning member 24 of the embodiment has a target positioning portion 241 and a plurality of concentrating portions 242 surrounding the target positioning portion 241. The target positioning portion 241 is represented by a plurality of adjacently arranged convex lens structures. Each concentrating portion 242 is presented in a single convex lens configuration.
