Description
本創作係有關於一種位置量測之技術領域,尤其是指可單一信號源輸入多種感測資訊輸出之一種可程式線性位移感測裝置。 This creation is about a technical field of position measurement, especially a programmable linear displacement sensing device that can input multiple sensing information outputs from a single signal source.
於工業自動化中,位置量測乃是一重要任務。諸如電腦化數值控制工具機(computed numerically controlled(CNC)machines)、鑽頭(drill bits)、機器人手臂(robot arm)、雷射切割器(laser cutter)之裝置等等,都需要精確的位置量測以用於反饋控制(feedback control)。期望以高取樣率(sampling rate)進行位置量測以致於能進行反饋控制。 In industrial automation, position measurement is an important task. Accurate position measurements, such as computed numerically controlled (CNC) machines, drill bits, robot arms, laser cutters, etc. For use in feedback control. It is desirable to perform position measurement at a high sampling rate so that feedback control can be performed.
舉例言之,常見光學編碼器(optical encoder)係用以量測絕對或相對位置。典型而言,具有規律性間隔標記之標尺(scale)與感測器一起使用,用以量測介於兩個標的間之相對位置。常見之光學編碼器依功能大致可區分:增量式線性編碼器(Incremental linear encoder)僅能量測位於該標尺上標記內之相對位置。 For example, a common optical encoder is used to measure absolute or relative position. Typically, a scale with regularly spaced marks is used with the sensor to measure the relative position between the two targets. A common optical encoder is roughly distinguishable by function: an incremental linear encoder only measures the relative position within the mark on the scale.
相對位置編碼器(relative position encoder)係持續追蹤橫越過標記之數量以判定相對位置。 The relative position encoder continuously tracks the number of traverse marks to determine the relative position.
絕對位置編碼器能判定絕對位置,且絕對位置編碼器(absolute position encoder)不需要記憶體及電源以儲存最後 的位置,因此適用於某些應用中。此外,絕對位置編碼器係能於啟動時提供一絕對位置,而相對位置編碼器典型而言需要去定位起始位置(start point),於某些應用時可能並不實用。 The absolute position encoder can determine the absolute position, and the absolute position encoder does not require memory and power to store the last The location is therefore suitable for some applications. In addition, absolute position encoders provide an absolute position at start-up, while relative position encoders typically need to locate the start point, which may not be practical in some applications.
習知絕對位置編碼器,需使用獨特的編碼樣式以量測每一個位置。儘管此種編碼器係使用標尺,惟只有在樣式改變時,才會判定有位置改變。於此情形中,位置估計(position estimate)之解析度受限於該樣式之解析度。 Conventional absolute position encoders require a unique coding pattern to measure each position. Although such an encoder uses a scale, it is determined that there is a change in position only when the style is changed. In this case, the resolution of the position estimate is limited by the resolution of the pattern.
同樣的,習知相對線性編碼器,利用光學偵測標尺上之標記以量測線性位置,該標記係平行於讀取頭(readhead)固設於一預設位置。然而,所得到之位置解析度亦被標尺上之標記解析度所限定。舉例言之,於該標尺上之標記係可能以40微米(micron)之解析度列印,故其精度被限制在40微米(micron)以下,而無法高於40微米。 Similarly, a conventional relative linear encoder utilizes a mark on an optical detection scale to measure a linear position that is fixed to a predetermined position parallel to the readhead. However, the resulting position resolution is also limited by the degree of mark resolution on the scale. For example, the marking on the scale may be printed at a resolution of 40 microns, so the accuracy is limited to less than 40 microns (micron) and not higher than 40 microns.
為了增進解析度,曾有業者提出教案,使用兩個標尺,各標尺於檢測方向上對齊且具有週期之標尺樣式,例如白色及黑色之標記。該標尺係由一側被照亮,且一光二極體係感測到穿透該兩個標尺至另一側之光線,隨著該標尺相對彼此移動,該光二極體之信號係介於一最大及一最小之強度值(intensity value)間變化。使用一解調程序(demodulation process)以判定該信號之相(phase),其係被轉變為相對位置,該相對位置係能以高於標尺解析度的解析度被還原。 In order to improve the resolution, the manufacturer has proposed a lesson plan, using two rulers, each of which is aligned in the detection direction and has a periodic scale pattern, such as white and black marks. The scale is illuminated by one side, and a photodiode system senses light that penetrates the two scales to the other side. As the scale moves relative to each other, the signal of the photodiode is between a maximum And a change between the minimum intensity values. A demodulation process is used to determine the phase of the signal, which is converted to a relative position that can be restored with a resolution above the scale resolution.
然而,此種設計僅提供相對位置。為了擁有判定絕對位置之能力,某些複合式編碼器係使用額外的標尺,如此反增加了系統之成本與複雜性。此種複合式編碼器係使用個別之標尺來量測增量位置與絕對位置,但該複合式編碼器需要使用兩個讀取頭,第一讀取頭用以讀取該增量位置,且第二讀取 頭用以讀取該絕對位置。 However, this design only provides relative position. In order to have the ability to determine the absolute position, some composite encoders use an additional scale, which increases the cost and complexity of the system. The composite encoder uses an individual scale to measure the incremental position and the absolute position, but the composite encoder requires two read heads, the first read head is used to read the incremental position, and Second reading The head is used to read the absolute position.
由上述習知編碼器之結構與限制可知,都需配合一標尺,緃是使磁性碼碼器亦需配合一磁尺使用,且都無法解決使用單一編碼器取得之單一感測訊號,同時輸出相對位置與絕對位置等多種資訊之需求。除此之外,上述光學式或磁性編碼器,都十分容易受環境之清潔、溫度等等影響,導致精準度的喪失。 It can be seen from the structure and limitation of the above-mentioned conventional encoder that a scale is required, so that the magnetic code encoder also needs to be used with a magnetic scale, and the single sensing signal obtained by using a single encoder cannot be solved, and the output is simultaneously output. The need for multiple information such as relative position and absolute position. In addition, the above optical or magnetic encoders are very susceptible to environmental cleanliness, temperature, etc., resulting in loss of accuracy.
有鑑於上述習知技藝之問題與缺失,本創作之主要目的,乃在於提供一種可程式線性位移感測裝置,藉由結構的設計,提供單一信號源輸入多種感測資訊輸出之需求。 In view of the above problems and deficiencies of the prior art, the main purpose of the present invention is to provide a programmable linear displacement sensing device, which provides a single signal source for inputting a plurality of sensing information outputs by a structural design.

以下請參照相關圖式進一步說明本創作可程式線性位移感測裝置實施例,為便於理解本創作實施方式,以下相同元件係採相同符號標示說明。 Hereinafter, the embodiment of the present programmable linear displacement sensing device will be further described with reference to the related drawings. For the purpose of understanding the present embodiment, the same components are denoted by the same reference numerals.
請參閱第1至6圖所示,有關可程式線性位移感測裝置,係用以對具導磁之被測物P進行線性運動時之量測;其包含一讀取頭1、一波形處理單元2、一A/D處理單元3、一控制單元4、及至少一個輸出連接埠5。 Please refer to FIGS. 1 to 6 for a programmable linear displacement sensing device for measuring linear motion of a magnetically permeable object P; it includes a read head 1 and a waveform processing The unit 2, an A/D processing unit 3, a control unit 4, and at least one output port 5.
上述讀取頭1(如第1至4圖所示),係用以對一被測物P(導磁體)提供一磁場,且該磁場會受被測物P的位移(或遠近)位置而變化,讓讀取頭1可依磁場之變化輸出一磁電訊號M。所述讀取頭1包含一磁性體12及一磁感測單元14。所述磁性體12透過不同之磁極排列方式,可於讀取頭1前端形成預期之磁場(磁力線)分布,當被測物P趨近磁性體12時會令 磁場(磁力線)分布變化,而磁感測單元14係配置於磁性體12之前方,依磁場(磁力線)分布變化連續輸出一磁電訊號M,該磁電訊號M大小與被測物P讀取頭1之位移量呈正比(距離呈反比)。 The read head 1 (shown in Figures 1 to 4) is used to provide a magnetic field to a measured object P (the magnetizer), and the magnetic field is subject to the displacement (or near and far) position of the measured object P. The change allows the read head 1 to output a magnetic signal M according to the change of the magnetic field. The read head 1 includes a magnetic body 12 and a magnetic sensing unit 14 . The magnetic body 12 can form a desired magnetic field (magnetic field line) distribution at the front end of the reading head 1 through different magnetic pole arrangement manners, and when the measured object P approaches the magnetic body 12, The magnetic field (magnetic line) is distributed, and the magnetic sensing unit 14 is disposed in front of the magnetic body 12, and continuously outputs a magnetic signal M according to the distribution of the magnetic field (magnetic line). The size of the magnetic signal M and the object P are read. The amount of displacement is proportional (distance is inversely proportional).
例如第2、4圖所示實施例中,緃軸代表為磁電訊號M的大小(數字越大表示磁電訊號M越強),而橫軸則是被測物P行程S中經讀取頭1之位移量(數字越大表示經讀取頭1之位移量越大);由於該磁電訊號M大小與被測物P行經讀取頭1之位移量呈正比,故磁電訊號M會呈現一趨勢上升之連續曲線MS1。 For example, in the embodiment shown in FIGS. 2 and 4, the x-axis represents the magnitude of the magnetoelectric signal M (the larger the number, the stronger the magneto-optical signal M), and the horizontal axis is the object P, the stroke S in the read head 1 The displacement amount (the larger the number, the larger the displacement amount of the read head 1); since the magnitude of the magnetoelectric signal M is proportional to the displacement of the object P through the read head 1, the magnetoelectric signal M exhibits a tendency The continuous curve MS1 of ascending.
又例如第3、4圖所示實施例中,緃軸代表為磁電訊號M的大小(數字越大表示磁電訊號M越強),而橫軸則是被測物P行程S中相對讀取頭1之距離(數字越大表示距離越遠);由於該磁電訊號M大小與被測物P相距讀取頭1之距離呈反比,故磁電訊號M會呈現一趨勢下降之連續曲線MS2。 For example, in the embodiments shown in FIGS. 3 and 4, the x-axis represents the magnitude of the magnetoelectric signal M (the larger the number, the stronger the magneto-optical signal M), and the horizontal axis is the relative read head of the object P in the stroke S. The distance of 1 (the larger the number indicates the farther distance); since the magnitude of the magnetoelectric signal M is inversely proportional to the distance of the object P from the reading head 1, the magnetoelectric signal M exhibits a continuous decreasing trend MS2.
上述波形處理單元2,係與讀取頭1電氣連接,對接收之磁電訊號M進行雜訊去除,將取樣區間外之磁電訊號M加以去除,避免雜訊的干擾以及後續無效之虛功轉換。 The waveform processing unit 2 is electrically connected to the read head 1 to perform noise removal on the received magnetoelectric signal M, and removes the magnetic signal M outside the sampling interval to avoid noise interference and subsequent invalid virtual power conversion.
上述A/D轉換單元3(A/D conversion unit),請參閱第4至5圖,係將連續之磁電訊號M轉換成階梯形狀之數位信號D,利用此一轉換將磁感訊號M所構成之連續曲線MS1、MS2,轉換成一連續階梯形狀之數位信號D。 The A/D conversion unit 3 (A/D conversion unit), as shown in FIGS. 4 to 5, converts the continuous magnetoelectric signal M into a stepped-shaped digital signal D, and uses the conversion to form the magnetic signal M. The continuous curves MS1, MS2 are converted into a digital signal D of a continuous step shape.
常見作法取第4圖之連續曲線MS2作說明,可將磁感訊號M所構成之連續曲線MS2對應行程S及磁電訊號M大小,分割成若干數區段;例如磁電訊號M由小至大分成M0-M10區段,對應行程S分成S0-S10區段,如此便可取得一連續階梯形狀之數位信號D,亦可精准的對應被測物P於行程S中的任一位置及其磁電訊號M的大小,當然前述之區段可依精密度要求變化設計。上述之舉例並不作為本創作實施之限定。 The common method takes the continuous curve MS2 of FIG. 4 as a description, and the continuous curve MS2 composed of the magnetic induction signal M can be divided into a plurality of segments corresponding to the stroke S and the magnitude of the magnetoelectric signal M; for example, the magnetoelectric signal M is divided into small and large segments. In the M0-M10 segment, the corresponding stroke S is divided into S0-S10 segments, so that a continuous step-shaped digital signal D can be obtained, and the measured object P can be accurately corresponding to any position in the stroke S and its magnetoelectric signal. The size of M, of course, the aforementioned sections can be designed according to the precision requirements. The above examples are not to be construed as limiting the implementation of the present invention.
上述控制單元4,係為一單晶片用以儲存並執行使用者預先載入之程式或設定。接收A/D轉換單元3輸出被測物P整個行程S之數位信號D並對其編碼,用於後續感測作動時可依使用者設定,將接收之數位信號D匹配編碼,且依程式對應編碼所作之設定,選擇性的輸出至少一運算訊號。 The control unit 4 is a single chip for storing and executing a program or setting preloaded by the user. The receiving A/D conversion unit 3 outputs the digital signal D of the entire stroke S of the measured object P and encodes it, and can be used for matching the digital signal D of the received digital signal D according to the user setting for subsequent sensing actuation, and corresponding to the program The setting made by the code selectively outputs at least one operation signal.
請參閱第5、6圖所示,常見作法係將由多數磁電訊號M所構成之連續曲線MS1、MS2,對應行程S及磁電訊號M分割成若干數區段,並對交叉之格點進行編碼(如第6圖之二進制碼),而取樣之格點可依精密度要求變化設計,如此便可定義行程S中任一位置(磁電訊號M)之編碼。上述之舉例並不作為本創作實施之限定。 Referring to Figures 5 and 6, the common practice is to divide the continuous curves MS1, MS2 composed of most of the magnetoelectric signals M into corresponding segments S and the magnetic signal M into a number of segments, and encode the intersecting lattice points ( As shown in the binary code of Figure 6, the sampling grid can be designed according to the precision requirements, so that the encoding of any position (magnet signal M) in the stroke S can be defined. The above examples are not to be construed as limiting the implementation of the present invention.
該控制單元4,係與A/D轉換單元3電氣連接,用以接收該數位信號D提供控制單元運算4(對應編碼),該控制單元4具有至少一個以上之訊號/資料輸出埠44、及一程式輸入埠46。所述訊號/資料輸出埠44係用以提供控制單元4輸出運算訊號,且該訊號/資料輸出埠44並與輸出連接埠5電氣連接。所述程式輸入埠46係用以提供外部電腦(控制器)連接(圖中未示),並接收外部電腦輸入之運算程式或相關設定,以便使用者程式化控制單元4之設定及對應各訊號/資料輸出埠44輸出運算訊號等。實施時,該程式輸入埠46包含(但不限)USB插座、RS232插座、排線端子插座、藍芽模組等形態,提供外部電腦(控制器)以有線或無線方式連接。 The control unit 4 is electrically connected to the A/D conversion unit 3 for receiving the digital signal D to provide a control unit operation 4 (corresponding code), the control unit 4 having at least one signal/data output port 44, and A program is entered at 46. The signal/data output port 44 is used to provide the control unit 4 to output an operation signal, and the signal/data output port 44 is electrically connected to the output port 埠5. The program input port 46 is configured to provide an external computer (controller) connection (not shown), and receive an operation program or related settings input by an external computer, so that the user can program the control unit 4 and corresponding signals. / Data output 埠 44 output operation signal, etc. In implementation, the program input port 46 includes (but is not limited to) a USB socket, an RS232 socket, a cable terminal socket, a Bluetooth module, etc., and provides an external computer (controller) to be connected by wire or wirelessly.
上述輸出連接埠5,係用以提供外部設備(圖中未示)電氣連接之端口,包含(但不限)電氣接點(焊接點)、接頭、插座、訊號線等等。 The output port 埠5 is used to provide a port for electrical connection of an external device (not shown), including (but not limited to) electrical contacts (solder joints), connectors, sockets, signal lines, and the like.
是以,上述即為本創作所提供一較佳實施例可程式線性位移感測裝置,各部構件及組裝方式之介紹,茲再將本創作之實施例作動特點介紹如下。 Therefore, the above is a preferred embodiment of the programmable linear displacement sensing device, the description of each component and the assembly method, and the actuation features of the present embodiment are described below.
首先,讀取頭1對應被測物P線性移動之路徑設置,以感測被測物P移動狀態,例如該被測物於移動路徑S之絕對位置,或被測物P 相對讀取頭1之相對位置。 First, the read head 1 is arranged corresponding to the path in which the measured object P moves linearly to sense the moving state of the measured object P, for example, the absolute position of the measured object on the moving path S, or the measured object P Relative to the relative position of the read head 1.
由於被測物P移動行程S的各個位置,其對讀取頭1之磁變化量已被記錄,故假設當被測物P於行程S中運動時,讀取頭1會依被測物P位置反應不同之磁電訊號M至A/D轉換單元3,讓A/D轉換單元3將磁感訊號M轉換成數位信號D,並傳遞至控制單元4讓其進行比對,以取得對應之編碼,繼而依使用者預先之設定,選擇性的對應訊號/資料輸出埠44輸出運算訊號,如此連接於輸出連接埠5之外部設備,則可取得該運算訊號,以利對被測物P位移運動之反饋控制。 Since the measured object P moves each position of the stroke S and its magnetic change amount to the reading head 1 has been recorded, it is assumed that when the measured object P moves in the stroke S, the reading head 1 depends on the measured object P. The positional response is different from the magnetoelectric signal M to the A/D conversion unit 3, and the A/D conversion unit 3 converts the magnetic induction signal M into a digital signal D, and transmits it to the control unit 4 for comparison to obtain the corresponding code. Then, according to the user's preset setting, the selective corresponding signal/data output 埠44 outputs an operation signal, and thus connected to the external device of the output port 5, the operation signal can be obtained to facilitate the displacement movement of the measured object P. Feedback control.
由於被測物P於行程S中的各點都被編碼化,故緃使電力中斷後再次回覆時,被測物P無需返回原點,本創作之可程式線性位移感測裝置,仍可直接取得該被測物P於行程S中任一位置資訊。 Since the object P is encoded at each point in the stroke S, when the power is interrupted and then returned again, the object P does not need to return to the origin, and the programmable linear displacement sensing device of the present invention can still be directly Obtaining information of any position of the object P in the stroke S.

The 5 assembly is housed in a casing B1.
請參閱第8圖所示,係本創作可程式線性位移感測裝置再一實施例,係將波形處理單元2、A/D處理單元3、控制單元4、及輸出連接埠5總成容置於一殼體B2內,而讀取頭1則遠離殼體B2設置,並配合導線電氣連接波形處理單元2。 Please refer to FIG. 8 , which is another embodiment of the programmable linear displacement sensing device. The waveform processing unit 2 , the A/D processing unit 3 , the control unit 4 , and the output port 5 assembly are accommodated. In a casing B2, the reading head 1 is disposed away from the casing B2, and is electrically connected to the waveform processing unit 2 in cooperation with the wires.
以上所述說明,僅為本創作的較佳實施方式而已,意在明確本創作的特徵,並非用以限定本創作實施例的範圍,本技術領域內的一般技術人員根據本創作所作的均等變化,以及本領域內技術人員熟知的改變,仍應屬本創作涵蓋的範圍。 The above description is only for the preferred embodiment of the present invention, and is intended to clarify the features of the present invention, and is not intended to limit the scope of the present embodiment, and the average variation made by those skilled in the art according to the present creation.
