Description
本發明係關於一種軌跡輸入裝置，特別是一種具有一感應模組與一操控模組，且感應模組與操控模組之間可進行雙向溝通的軌跡輸入裝置。 The invention relates to a track input device, in particular to a track input device having a sensor module and a control module, and two-way communication between the sensor module and the control module.
隨著多媒體電腦的普及化，已成為大多數使用者作為處理工作或是娛樂的工具，而使用者可利用滑鼠、軌跡球、鍵盤或是數位板作為輸入至多媒體電腦的周邊輸入裝置。其中，藉由數位板以及數位筆的書寫區域將文字或是圖式輸入至多媒體電腦的方式，最為符合使用者書寫習慣的方式。且為了更符合書寫習慣，數位筆可偵測使用者將數位筆施加於數位板上的筆壓，以描繪出不同筆觸的線條。而數位板以及數位筆主要又可分為電容式、電阻式或是電磁式等種類。 With the popularization of multimedia computers, most users have become tools for processing work or entertainment, and users can use a mouse, trackball, keyboard or tablet as input devices for input to multimedia computers. Among them, the way of inputting text or graphics into a multimedia computer by the writing area of the tablet and the digital pen is most suitable for the user's writing habits. In order to better conform to the writing habits, the digital pen can detect the pen pressure applied by the user to the digital pen to draw lines of different strokes. The digital tablet and the digital pen can be mainly classified into a capacitive type, a resistive type or an electromagnetic type.
其中電磁式的數位筆係利用振盪電路以及線圈發出電磁波給數位板，數位板再感應電磁波並據以進行定位獲傳送筆壓等額外資訊。但是使用單一組的振盪電路以及線圈進行定位和傳送額外資訊的作業時，振盪電路以及線圈得要輪流進行不同的作業。若使用兩組振盪電路以及線圈，又會有兩組電磁波可能互相干擾的問題。 The electromagnetic digital pen system uses an oscillating circuit and a coil to emit electromagnetic waves to the digital board, and the digital board senses the electromagnetic wave and performs additional information such as positioning and transmission of the pen pressure. However, when a single set of oscillating circuits and coils are used for positioning and transmitting additional information, the oscillating circuit and the coils have to perform different operations in turn. If two sets of oscillating circuits and coils are used, there will be two sets of electromagnetic waves that may interfere with each other.
再者，傳統上只能由數位筆單方面地傳送筆壓等資訊給數位板，數位板並不會與數位筆進行溝通。因此數位板並無法對數位筆進行控制，而使得在應用上缺乏彈性。 Moreover, traditionally, only digital pens can be used to unilaterally transmit information such as pen pressure to the tablet, and the tablet does not communicate with the pen. Therefore, the tablet cannot control the digital pen, which makes it less flexible in application.
為了解決上述問題，本發明提供一種軌跡輸入裝置，其包括一感應模組以及一操控模組。其中感應模組包括一感應線圈、一第一通訊單元以及一第一控制單元，而操控模組包括一定位線圈、多個動作單元、一第二通訊單元以及一第二控制單元。 In order to solve the above problems, the present invention provides a track input device including a sensor module and a control module.

反之，當電池的剩餘電量大於一第二門檻值時，第 二控制單元可產生一充電結束訊號以及一第四控制訊號。當第一控制單元透過第一通訊單元以及第二通訊單元接收第四控制訊號時，第一控制單元可令感應線圈停止發出充電訊號。當開關接收充電結束訊號時，開關可使定位線圈連接到振盪電路。 Conversely, when the remaining battery power is greater than a second threshold, The second control unit can generate a charging end signal and a fourth control signal. When the first control unit receives the fourth control signal through the first communication unit and the second communication unit, the first control unit may stop the induction coil from issuing the charging signal.

本發明提供一種軌跡輸入裝置，其包括一感應模組以及一操控模組。軌跡輸入裝置可做為一計算機的周邊裝置，且計算機可具有一顯示器。使用者可操作操控模組，以控制顯示於顯示器上的一游標並對計算機進行操作。 The invention provides a track input device, which comprises an induction module and a control module. The track input device can be used as a peripheral device of a computer, and the computer can have a display. The user can operate the control module to control a cursor displayed on the display and operate the computer.
請先參照「第1圖」，其係為一實施範例之軌跡輸入裝置之方塊示意圖。 Please refer to "FIG. 1" first, which is a block diagram of a track input device of an embodiment.
軌跡輸入裝置其包括感應模組20以及操控模組30。舉例而言，感應模組20可以是電磁式數位板或電磁式繪圖板，而操控模組30可以是電磁式數位筆。由於感應模組20以及操控模組30採用電磁式的定位方式，因此使用者操作操控模組30時，操控模組30可以不用接觸到感應模組20。但使用者也可將操控模組30抵靠於感應模組20的表面並滑動，而操作模組30可以感測使用者施加的筆壓。 The track input device includes a sensor module 20 and a control module 30. For example, the sensing module 20 can be an electromagnetic tablet or an electromagnetic drawing tablet, and the control module 30 can be an electromagnetic digital pen. Since the sensing module 20 and the control module 30 adopt an electromagnetic positioning manner, when the user operates the control module 30, the control module 30 does not need to touch the sensing module 20. However, the user can also press the control module 30 against the surface of the sensor module 20 and slide, and the operation module 30 can sense the pen pressure applied by the user.
感應模組20包括一感應線圈21、一第一通訊單元 22以及一第一控制單元23；而操控模組30包括一定位線圈31、一第二通訊單元32、一第二控制單元33以及多個動作單元34。其中感應線圈21以及第一通訊單元22與第一控制單元23相連；定位線圈31、第二通訊單元32以及每一個動作單元34都可以與第二控制單元33相連。 The sensing module 20 includes an induction coil 21 and a first communication unit. 22 and a first control unit 23; and the control module 30 includes a positioning coil 31, a second communication unit 32, a second control unit 33, and a plurality of action units 34. The induction coil 21 and the first communication unit 22 are connected to the first control unit 23; the positioning coil 31, the second communication unit 32, and each of the action units 34 can be connected to the second control unit 33.
為了定位操控模組30相對於感應模組20的位置，定位線圈31發出一定位訊號，感應線圈21利用電磁共振(electromagnetic vibration)的原理接收定位訊號並據以輸出一軌跡訊號。而軌跡訊號對應使用者以操控模組30畫出的軌跡。 In order to locate the position of the control module 30 relative to the sensing module 20, the positioning coil 31 sends a positioning signal, and the induction coil 21 receives the positioning signal by using the principle of electromagnetic vibration and outputs a tracking signal accordingly. The track signal corresponds to the trajectory drawn by the user with the control module 30.
第一控制單元23與第二控制單元33之間，可透過第一通訊單元22以及第二通訊單元32進行雙向溝通。為了進行雙向溝通，第一通訊單元22輸出一第一控制訊號並接收一第二控制訊號，而第二通訊單元32用以接收第一控制訊號並輸出第二控制訊號。其中第一通訊單元22以及第二通訊單元32可以是一射頻積體電路(Radio frequency integrated circuit，RFIC)。然而第一通訊單元22以及第二通訊單元32亦可採用其他低功耗且不會與定位訊號產生干擾的通訊方式，例如RF2.4G等。 The first control unit 23 and the second control unit 33 can communicate bidirectionally through the first communication unit 22 and the second communication unit 32. For the two-way communication, the first communication unit 22 outputs a first control signal and receives a second control signal, and the second communication unit 32 is configured to receive the first control signal and output the second control signal. The first communication unit 22 and the second communication unit 32 may be a radio frequency integrated circuit (RFIC). However, the first communication unit 22 and the second communication unit 32 may also adopt other communication methods that are low in power consumption and do not interfere with the positioning signal, such as RF2.4G.
每一個動作單元34都可產生一動作訊號。動作單元34可以是一筆壓感測器、一按鈕、一滾輪或是一電阻式調整器。舉例而言，操控模組30的外觀可以呈筆型，筆桿外側可配置至少一個按鍵，而在筆尖以及筆芯處可配置筆壓偵測器。而電阻式調整器可以是可變電阻器(variable resistor)，例如可實作成一旋 鈕(knob)或是一滑桿(sliding bar)。按鈕、滾輪或是電阻式調整器可依據計算機所執行之應用程式有不同的定義。舉例而言，當使用中的應用程式是繪圖軟體時，操控模組30可以模仿各種畫筆；而使用者可以透過電阻式調整器來調整畫筆的種類、粗細、顏色或與畫紙之間的接觸角度。 Each action unit 34 can generate an action signal. The action unit 34 can be a pressure sensor, a button, a roller or a resistive adjuster. For example, the appearance of the manipulation module 30 may be a pen type, at least one button may be disposed outside the pen holder, and the pen pressure detector may be disposed at the pen tip and the refill. The resistance regulator can be a variable resistor, for example, it can be implemented as a rotation. Knob or a sliding bar. Buttons, scroll wheels, or resistive adjusters can be defined differently depending on the application being executed by the computer. For example, when the application in use is a drawing software, the manipulation module 30 can simulate various brushes; and the user can adjust the type, thickness, color or contact with the drawing paper through the resistance adjuster. angle.
再舉例而言，當動作單元34是筆壓感測器時，其可偵測使用者施加的筆壓，並輸出代表筆壓強度的動作訊號。當動作單元34是按鈕時，其可發出代表按鈕被按壓與否的動作訊號。當動作單元34是滾輪時，其可發出代表滾輪滾動方向以及滾動距離的動作訊號。當動作單元34是旋扭或滑桿時，其可發出代表當前的電阻值的動作訊號，也可發出代表移動方向以及移動距離的動作訊號。 For another example, when the action unit 34 is a pen pressure sensor, it can detect the pen pressure applied by the user and output an action signal representing the pen pressure strength. When the action unit 34 is a button, it can issue an action signal indicating whether the button is pressed or not. When the action unit 34 is a scroll wheel, it can emit an action signal representing the scrolling direction of the scroll wheel and the scrolling distance. When the action unit 34 is a knob or a slider, it can emit an action signal representing the current resistance value, and can also emit an action signal representing the direction of movement and the distance of movement.
請參照「第2圖」，其係為一實施範例之第一控制單元與第二控制單元之雙向溝通流程圖。 Please refer to "FIG. 2", which is a two-way communication flow chart of the first control unit and the second control unit of an embodiment.
首先，第一控制單元23產生第一控制訊號(步驟S110)，並令第一通訊單元22將第一控制訊號發送給第二通訊單元32。第二控制單元33從第二通訊單元32接收第一控制訊號(步驟S120)。接著第二控制單元33可依據第一控制訊號從至少一個動作單元34接收至少一個動作訊號，並依據接收的動作訊號產生第二控制訊號(步驟S130)。 First, the first control unit 23 generates a first control signal (step S110), and causes the first communication unit 22 to send the first control signal to the second communication unit 32. The second control unit 33 receives the first control signal from the second communication unit 32 (step S120). The second control unit 33 can receive at least one action signal from the at least one action unit 34 according to the first control signal, and generate a second control signal according to the received action signal (step S130).
於步驟S130之中，第一控制訊號可指定至少一個動作單元34；第二控制單元33再從被指定的動作單元34接收至少 一個動作訊號，並依據接收的動作訊號產生第二控制訊號。舉例而言，第一控制單元23可能需要定期獲得筆壓強度，因此可定期發出內容為要求當前筆壓強度的第一控制訊號。當第二控制單元33收到此一第一控制訊號後，便去讀取筆壓偵測器所產生的動作訊號，再將讀取到的動作訊號作為第二控制訊號回傳給第一控制單元23。 In step S130, the first control signal may specify at least one action unit 34; the second control unit 33 receives at least the specified action unit 34 from the action unit 34. An action signal generates a second control signal according to the received motion signal. For example, the first control unit 23 may need to periodically obtain the pen pressure strength, so the first control signal that is required to require the current pen pressure strength may be periodically issued. After receiving the first control signal, the second control unit 33 reads the action signal generated by the pen pressure detector, and then returns the read motion signal as the second control signal to the first control. Unit 23.
又例如，當使用中的應用程式只需要筆壓強度以及按鈕被按壓與否時，第一控制單元23可以只向第二控制單元33要求筆壓偵測器以及按鈕所產生的動作訊號。如此一來，可使特定動作單元34失能(disable)，以避免因使用者誤觸不應產生作用的特定動作單元34而發生程式處理錯誤或是其他預料外的錯誤結果。 For another example, when the application in use only needs the pen pressure strength and the button is pressed or not, the first control unit 23 can only request the pen pressure detector and the action signal generated by the button to the second control unit 33. In this way, the specific action unit 34 can be disabled to avoid program processing errors or other unexpected erroneous results due to the user accidentally touching the particular action unit 34 that should not be active.
產生第二控制訊號後，第二控制單元33令第二通訊單元32將第二控制訊號發送給第一通訊單元22。第一控制單元23從第一通訊單元22接收第二控制訊號，且可從感應線圈21接收軌跡訊號，再依據軌跡訊號或第二控制訊號產生一輸出訊號(步驟S140)。 After the second control signal is generated, the second control unit 33 causes the second communication unit 32 to send the second control signal to the first communication unit 22. The first control unit 23 receives the second control signal from the first communication unit 22, and receives the track signal from the induction coil 21, and generates an output signal according to the track signal or the second control signal (step S140).
如此一來，利用感應模組20與操控模組30之間的雙向溝通機制，可同時重送定位訊號、第一控制訊號以及第二控制訊號，進而使感應模組20與操控模組30之間的訊息同步。雖然第一控制訊號以及第二控制訊號的內容可如「第2圖」之實施範例所述，但亦可具有其他內容。例如操控模組30可依據預設 的排程(scheduling)主動將動作訊號作為第二控制訊號透過第一通訊單元22與第二通訊單元32發送給感應模組20，通訊模組30可再透過第一通訊單元22與第二通訊單元32回覆確收(acknowledgement，ACK)作為第一控制訊號。 In this way, the two-way communication mechanism between the sensing module 20 and the control module 30 can simultaneously retransmit the positioning signal, the first control signal, and the second control signal, thereby enabling the sensing module 20 and the control module 30. The messages are synchronized. Although the contents of the first control signal and the second control signal may be as described in the implementation example of FIG. 2, they may have other contents. For example, the control module 30 can be preset according to Scheduling actively transmits the action signal as the second control signal to the sensor module 20 through the first communication unit 22 and the second communication unit 32, and the communication module 30 can further transmit the second communication unit through the first communication unit 22. Unit 32 replies with an acknowledgement (ACK) as the first control signal.
根據一實施範例，感應線圈21可發出一充電訊號；且定位線圈31可接收充電訊號並產生一電能訊號，作為供操控模組30運作的電力來源。請參照「第3圖」，其係為一實施範例之操控模組之方塊示意圖。 According to an embodiment, the induction coil 21 can emit a charging signal; and the positioning coil 31 can receive the charging signal and generate an electrical signal as a power source for the operation of the control module 30. Please refer to "FIG. 3", which is a block diagram of a control module of an embodiment.
操控模組另可包括一開關35、一振盪電路36以及一整流單元37，其中開關35可用以使定位線圈31連接到振盪電路36或是整流單元37。振盪電路36可連接第二控制單元33以及開關35，並用以令定位線圈31產生定位訊號。更詳細地說，振盪電路36可依據第二控制單元33命令產生一振盪訊號傳給定位線圈31，定位線圈31再把振盪訊號轉換成電磁波型態的定位訊號。較佳的是，感應模組20所發出的充電訊號與操控模組30所發出的定位訊號採用不同頻率，以避免訊號之間互相干擾。 The control module may further include a switch 35, an oscillating circuit 36 and a rectifying unit 37, wherein the switch 35 may be used to connect the positioning coil 31 to the oscillating circuit 36 or the rectifying unit 37. The oscillating circuit 36 can be connected to the second control unit 33 and the switch 35, and is used to cause the positioning coil 31 to generate a positioning signal. In more detail, the oscillating circuit 36 can command an oscillating signal to be transmitted to the positioning coil 31 according to the second control unit 33, and the positioning coil 31 converts the oscillating signal into an electromagnetic wave type positioning signal. Preferably, the charging signal sent by the sensing module 20 and the positioning signal sent by the control module 30 are at different frequencies to avoid mutual interference between the signals.
整流單元37可連接第二控制單元33以及開關35，並可從定位線圈31接收電能訊號，整流電能訊號再輸出給第二控制單元33。根據不同實施範例，電能訊號可僅傳送給第二控制單元33，再由第二控制單元23供電給第二通訊單元32或是動作單元34等其他電子元件。但整流單元37亦可直接連接第二通訊單元32、第二控制單元33或是動作單元34等各個電子元件，以 將電能訊號直接傳送給這些電子元件。 The rectifying unit 37 can be connected to the second control unit 33 and the switch 35, and can receive the electric energy signal from the positioning coil 31, and rectify the electric energy signal and output it to the second control unit 33. According to different embodiments, the power signal can be transmitted only to the second control unit 33, and then the second control unit 23 can supply power to the second communication unit 32 or other electronic components such as the action unit 34. However, the rectifying unit 37 can also directly connect the electronic components such as the second communication unit 32, the second control unit 33, or the action unit 34 to The power signal is transmitted directly to these electronic components.
根據一實施範例，操控模組30另可包括內藏式的一電池，以暫存電能訊號。請參照「第4圖」，其係為一實施範例之操控模組之方塊示意圖。電池38可連接整流單元37以及第二控制單元33，以儲存整流過的電能訊號，並輸出整流過的電能訊號給第二控制單元33。整流單元37可透過電池38與第二控制單元33連接。 According to an embodiment, the control module 30 may further include a built-in battery to temporarily store the power signal. Please refer to FIG. 4, which is a block diagram of a control module of an embodiment. The battery 38 can be connected to the rectifying unit 37 and the second control unit 33 to store the rectified electric energy signal and output the rectified electric energy signal to the second control unit 33. The rectifying unit 37 is connectable to the second control unit 33 via the battery 38.
第二控制單元33可根據電池38的剩餘電量判斷是否需要進行充電，並可利用第一通訊單元22以及第二通訊單元32與第一控制單元23進行溝通，以控制充電的流程。 The second control unit 33 can determine whether charging is required according to the remaining power of the battery 38, and can communicate with the first control unit 23 by using the first communication unit 22 and the second communication unit 32 to control the charging process.
請參照「第5圖」，其係為一實施範例之充電流程之流程圖。 Please refer to "figure 5", which is a flow chart of the charging process of an embodiment.
首先第二控制單元33可判斷電池38的剩餘電量是否小於一第一門檻值(步驟S210)，當電池38的剩餘電量小於第一門檻值時，軌跡輸入裝置執行以下步驟S220到步驟S240。當電池38的剩餘電量小於第一門檻值而需要進行充電時，第二控制單元33可產生一充電開始訊號以及一第三控制訊號(步驟S220)。其中充電開始訊號發送給開關35，而第三控制訊號發送給第一控制單元23。第一控制單元23可透過第一通訊單元22以及第二通訊單元32接收第三控制訊號。當第一控制單元23收到第三控制訊號時，可令感應線圈21開始發出充電訊號(步驟S230)。而當開關35接收充電開始訊號時，開關35可使定位線 圈31連接到整流單元37(步驟S240)。因此定位線圈31可接收充電訊號，並將充電訊號傳送給整流單元37進行整流，進而對電池38充電。 First, the second control unit 33 can determine whether the remaining power of the battery 38 is less than a first threshold (step S210). When the remaining power of the battery 38 is less than the first threshold, the trajectory input device performs the following steps S220 to S240. When the remaining amount of the battery 38 is less than the first threshold and charging is required, the second control unit 33 may generate a charging start signal and a third control signal (step S220). The charging start signal is sent to the switch 35, and the third control signal is sent to the first control unit 23. The first control unit 23 can receive the third control signal through the first communication unit 22 and the second communication unit 32. When the first control unit 23 receives the third control signal, the induction coil 21 can start to issue a charging signal (step S230). When the switch 35 receives the charging start signal, the switch 35 can make the positioning line The ring 31 is connected to the rectifying unit 37 (step S240). Therefore, the positioning coil 31 can receive the charging signal and transmit the charging signal to the rectifying unit 37 for rectification, thereby charging the battery 38.
當電池38的剩餘電量不小於第一門檻值時，第二控制單元33可判斷電池38的剩餘電量是否大於一第二門檻值(步驟S250)。當電池38的剩餘電量大於第二門檻值時，軌跡輸入裝置執行以下步驟S260到步驟S280。當電池38的剩餘電量大於第二門檻值而可以停止充電時，第二控制單元33可產生一充電結束訊號以及一第四控制訊號(步驟S260)。其中充電結束訊號發送給開關35，而第四控制訊號發送給第一控制單元23。第一控制單元23可透過第一通訊單元22以及第二通訊單元32接收第四控制訊號。當第一控制單元23收到第三控制訊號時，可令感應線圈21停止發出充電訊號(步驟S270)。而當開關35接收充電結束訊號時，開關35可進行切換並使定位線圈31連接到振盪電路36(步驟S280)。因此定位線圈31可繼續發送定位訊號，以定位操控模組30。 When the remaining power of the battery 38 is not less than the first threshold, the second control unit 33 may determine whether the remaining power of the battery 38 is greater than a second threshold (step S250). When the remaining amount of power of the battery 38 is greater than the second threshold, the trajectory input device performs the following steps S260 to S280. When the remaining power of the battery 38 is greater than the second threshold and the charging can be stopped, the second control unit 33 can generate a charging end signal and a fourth control signal (step S260). The charging end signal is sent to the switch 35, and the fourth control signal is sent to the first control unit 23. The first control unit 23 can receive the fourth control signal through the first communication unit 22 and the second communication unit 32. When the first control unit 23 receives the third control signal, the induction coil 21 can stop the charging signal from being sent (step S270). When the switch 35 receives the charging end signal, the switch 35 can switch and connect the positioning coil 31 to the oscillation circuit 36 (step S280). Therefore, the positioning coil 31 can continue to transmit the positioning signal to locate the steering module 30.
此外，操控裝置30亦可另包括一充電線圈，以同時接收充電訊號以及發送定位訊號。請參照「第6圖」以及「第7圖」，其分別為不同實施範例之操控模組之方塊示意圖。 In addition, the control device 30 can further include a charging coil to simultaneously receive the charging signal and transmit the positioning signal. Please refer to "Figure 6" and "Figure 7", which are block diagrams of the control modules of different implementation examples.
操控模組可另包括充電線圈39，且充電線圈39可用以接收充電訊號並產生電能訊號。整流單元37可連接充電線圈39以及第二控制單元33，用以整流電能訊號再輸出給第二控 制單元33。然而整流單元37與第二控制單元33之間也可有電池38以暫存整流過的電能訊號。較佳的是，感應模組20所發出的充電訊號與操控模組30所發出的定位訊號採用不同頻率，以避免訊號之間互相干擾。 The control module can further include a charging coil 39, and the charging coil 39 can be used to receive the charging signal and generate an electrical energy signal. The rectifying unit 37 can be connected to the charging coil 39 and the second control unit 33 for rectifying the electric energy signal and outputting to the second control Unit 33. However, there may also be a battery 38 between the rectifying unit 37 and the second control unit 33 for temporarily storing the rectified electric energy signal. Preferably, the charging signal sent by the sensing module 20 and the positioning signal sent by the control module 30 are at different frequencies to avoid mutual interference between the signals.
類似地，感應模組20也可包括一供電線圈以同時接收定位訊號並發出充電訊號。且類似於「第5圖」所述之充電流程，第一控制單元23可在收到第三控制訊號後才令感應線圈21或供電線圈發出充電訊號，並在收到第四控制訊號後令感應線圈21或供電線圈停止發出充電訊號，以避免供電線圈不斷發出充電訊號造成能源浪費。 Similarly, the sensing module 20 can also include a power supply coil to simultaneously receive the positioning signal and issue a charging signal. And similar to the charging process described in FIG. 5, the first control unit 23 can send the charging signal to the induction coil 21 or the power supply coil after receiving the third control signal, and after receiving the fourth control signal, The induction coil 21 or the power supply coil stops sending a charging signal to prevent the power supply coil from continuously emitting a charging signal, thereby wasting energy.
根據另一實施範例，操控模組30中可以有電池38，但沒有充電線圈39和整流單元37，如「第8圖」。電池38可以是可拆卸式的乾電池、鈕扣電池或是可充電電池，並只用以供電給操控模組30。 According to another embodiment, the control module 30 may have a battery 38, but no charging coil 39 and a rectifying unit 37, such as "Fig. 8". The battery 38 can be a detachable dry battery, a button battery or a rechargeable battery, and is only used to supply power to the control module 30.
綜上所述，感應模組可利用定位線圈與感應線圈對操控模組進行定位並獲得軌跡訊號，也可利用第一通訊單元與第二通訊單元與操控模組進行雙向溝通。且利用雙向溝通的機制，感應單元可以獲得所需的動作訊號，也可得知需要對操控模組進行充電的時機。且第一通訊單元與第二通訊單元可採用通訊距離較短但低功耗的通訊方式，而能夠提供長時間且頻繁地雙向溝通。此外，第一通訊單元與第二通訊單元的通訊可在數位通訊，因此不會與定位線圈發出的電磁波(定位訊號)產生干擾。 In summary, the sensing module can use the positioning coil and the induction coil to locate the control module and obtain the track signal, and can also use the first communication unit and the second communication unit to communicate with the control module in two directions. And using the mechanism of two-way communication, the sensing unit can obtain the required motion signal, and can also know the timing of charging the control module. Moreover, the first communication unit and the second communication unit can adopt a communication method with a short communication distance but low power consumption, and can provide long-term and frequent two-way communication. In addition, the communication between the first communication unit and the second communication unit can be digitally communicated, and thus does not interfere with electromagnetic waves (positioning signals) emitted by the positioning coil.
