The processing circuit 18 can read from the non-volatile memory 26 and execute the application program 28 to perform the temperature sensing function of the wearable electronic device 10. In detail, when the user wants to measure his own body temperature, the application 28 can be activated to enable the processing circuit 18 to switch the wearable electronic device 10 to the temperature measurement mode. In the temperature measurement mode, the button 12 will temporarily lose its touch function, and the temperature sensor 14 will be powered to start the temperature measurement. By executing the application program 28, the processing circuit 18 can calculate the temperature to be measured based on the signal from the temperature sensor 14. On the other hand, when the application 28 is not activated, the processing circuit 18 puts the wearable electronic device 10 in the touch mode. In the touch mode, the button 12 will resume the touch function and allow the user to perform related operations on the wearable electronic device 10 through the button 12, but the temperature sensor 14 is not powered at this time.

請參考第6圖。處理電路18包含切換電路30、電容數位轉換器(capacitance to digital converter；CDC)、類比數位轉換器(analog to digital converter；ADC)34、微處理單元以及記憶體38。切換電路30耦接於訊號傳輸通道16。當穿戴式電子裝置10處於上述的觸控模式時，微處理單元36會控制切換電路30將訊號傳輸通道16耦接至電容數位轉換器32，以使電容數位轉換器32得以將來自按鍵12的訊號轉換成一控制訊號，並將此控制訊號傳送給微處理單元 36，以使微處理單元36得以依據此控制訊號控制穿戴式電子裝置10的操作。此外，當穿戴式電子裝置10處於上述的溫度量測模式時，微處理單元36會控制切換電路30將訊號傳輸通道16耦接至類比數位轉換器34，以使類比數位轉換器34將來自溫度傳感器14的訊號轉換成一溫度訊號，並將此溫度訊號傳送給微處理單元36，以使微處理單元36得以依據此溫度訊號計算所要量測的溫度。值得注意地，切換電路30不會同時將訊號傳輸通道16耦接於電容數位轉換器32和類比數位轉換器34。因此，在任何時間點，電容數位轉換器32和類比數位轉換器34當中只有其中之一會耦接至訊號傳輸通道16。 Please refer to Figure 6. The processing circuit 18 includes a switching circuit 30, a capacitance to digital converter (CDC), an analog to digital converter (ADC) 34, a microprocessor unit, and a memory 38. The switching circuit 30 is coupled to the signal transmission channel 16. When the wearable electronic device 10 is in the above-mentioned touch mode, the micro-processing unit 36 controls the switching circuit 30 to couple the signal transmission channel 16 to the capacitance-to-digital converter 32, so that the capacitance-to-digital converter 32 can receive data from the buttons 12 The signal is converted into a control signal, and the control signal is sent to the micro-processing unit 36, so that the micro-processing unit 36 can control the operation of the wearable electronic device 10 according to the control signal. In addition, when the wearable electronic device 10 is in the above-mentioned temperature measurement mode, the micro-processing unit 36 controls the switching circuit 30 to couple the signal transmission channel 16 to the analog-to-digital converter 34, so that the analog-to-digital converter 34 receives the temperature The signal of the sensor 14 is converted into a temperature signal, and the temperature signal is sent to the micro-processing unit 36 so that the micro-processing unit 36 can calculate the temperature to be measured based on the temperature signal. It is worth noting that the switching circuit 30 does not couple the signal transmission channel 16 to the capacitance-to-digital converter 32 and the analog-to-digital converter 34 at the same time. Therefore, at any point in time, only one of the capacitance-to-digital converter 32 and the analog-to-digital converter 34 is coupled to the signal transmission channel 16.

在本發明一實施例中，溫度傳感器14包含參考電阻Rs及熱敏電阻Rt。其中，熱敏電阻Rt可以是負溫度係數(Negative Temperature Coefficient；NTC)熱敏電阻，而參考電阻Rs的電阻值大致上不會隨溫度而變化。當穿戴式電子裝置10處於上述的溫度量測模式時，溫度傳感器14會被供給兩個端電壓Vs和Vr。當溫度改變時，熱敏電阻Rt的電阻值也會跟著改變，因此處理電路18藉由量測溫度傳感器14的節點電壓Vo，即可準確地得到所要量測的溫度。此外，當穿戴式電子裝置10處於上述的觸控模式時，上述的兩個端電壓Vs和Vr不會被供給至溫度傳感器14，以節省電力的消耗。 In an embodiment of the present invention, the temperature sensor 14 includes a reference resistor Rs and a thermistor Rt. The thermistor Rt may be a negative temperature coefficient (NTC) thermistor, and the resistance value of the reference resistor Rs does not substantially change with temperature. When the wearable electronic device 10 is in the above-mentioned temperature measurement mode, the temperature sensor 14 will be supplied with two terminal voltages Vs and Vr. When the temperature changes, the resistance value of the thermistor Rt also changes. Therefore, the processing circuit 18 can accurately obtain the temperature to be measured by measuring the node voltage Vo of the temperature sensor 14. In addition, when the wearable electronic device 10 is in the aforementioned touch mode, the aforementioned two terminal voltages Vs and Vr will not be supplied to the temperature sensor 14 to save power consumption.

在本發明一實施例中，處理電路18可另包含記憶體38，用以儲存相關的程式碼及資料。 In an embodiment of the present invention, the processing circuit 18 may further include a memory 38 for storing related program codes and data.

請參考第7圖。第7圖是利用上述穿戴式電子裝置量10量測溫度時的流程圖。電子裝置量10進行溫度量測的流程包含下述步驟：步驟S70：處理電路18執行應用程式28，以將穿戴式電子裝置量10 切換至溫度量測模式；步驟S72：處理電路18依據來自訊號傳輸通道16的訊號，判斷在一預設時間(例如：10秒)內按鍵12是否有與皮膚接觸；若有偵測到按鍵12有與皮膚接觸，則進行步驟S74；反之，則進行步驟S78；步驟S74：處理電路18控制溫度傳感器14，以開始量測溫度；步驟S76：處理電路18依據來自溫度傳感器14的訊號計算出溫度，並控制螢幕20顯示所量測到的溫度；以及步驟S78：處理電路18將穿戴式電子裝置量10切換至觸控模式。 Please refer to Figure 7. Fig. 7 is a flow chart of the temperature measurement using the wearable electronic device 10. The process of measuring the temperature of the electronic device 10 includes the following steps: Step S70: The processing circuit 18 executes the application 28 to measure the wearable electronic device 10 Switch to the temperature measurement mode; step S72: the processing circuit 18 determines whether the button 12 is in contact with the skin within a preset time (for example: 10 seconds) according to the signal from the signal transmission channel 16; if the button 12 is detected If there is skin contact, go to step S74; otherwise, go to step S78; step S74: the processing circuit 18 controls the temperature sensor 14 to start measuring the temperature; step S76: the processing circuit 18 calculates the temperature based on the signal from the temperature sensor 14 , And control the screen 20 to display the measured temperature; and step S78: the processing circuit 18 switches the wearable electronic device 10 to the touch mode.

綜上所述，本發明通過接觸式量測的結構設計，將按鍵與螢幕設於穿戴式電子裝置同一面，方便使用者量測其額溫，故可提升現有穿戴式裝置的體溫量測準確度。配戴者不需再另外使用傳統量測體溫的儀器量測，即可準確量測本身的體溫，而大幅地提升自主健康管理的便利性。此外，本發明穿戴式電子裝置的按鍵及溫度傳感器可透過同一訊號傳輸通道，將觸控訊號及溫度訊號傳送至處理電路，而使按鍵可同時具有觸控及作為溫度感測端的功能。 In summary, through the structural design of contact measurement, the present invention arranges the button and the screen on the same side of the wearable electronic device, which is convenient for the user to measure his forehead temperature, so it can improve the accuracy of the body temperature measurement of the existing wearable device. Spend.
