參閱圖1、2，以下將說明本發明行車紀錄器資料備份方法的一實施例所包含之步驟。 Referring to Figures 1 and 2, the following will describe the steps included in an embodiment of the driving recorder data backup method of the present invention.

在步驟301中，該處理模組16判定是否符合至少一特定條件。當該處理模組16判定出符合該至少一特定條件時，流程進行步驟302；而當該處理模組16判定出不符合該至少一特定條件時，則重複步驟301。 In step 301, the processing module 16 determines whether at least one specific condition is met. When the processing module 16 determines that the at least one specific condition is met, the process proceeds to step 302; and when the processing module 16 determines that the at least one specific condition is not met, step 301 is repeated.

值得注意的是，在本實施例中，該至少一特定條件包括該處理模組16接收到一經由一駕駛人在該使用者輸入輸出介面15的輸入操作所產生的控制輸入訊號、該影像拍攝模組13拍攝之一在該當前時間點拍攝的當前影像之一偵測物件的移動軌跡異常變化、該影像拍攝模組13拍攝之該當前影像之該偵測物件的移動速度異常，該重力感測模組17感測之一在該當前時間點感測的感測值大於一閾值，但不以此為限，其中，當該使用者輸入介面15產生該控制輸入訊號時，表示該駕駛人認為有紀錄之需求故操作該使用者輸入輸出介面15；當該當前影像之該偵測物件的移動軌跡異常或移動速度異常時，表示其他車輛發生事故；當該感測值大於該閾值時，表示本車輛可能已發生碰撞事故。其中，該處理模組16是利用影像辨識中物件偵測技術判斷偵測物件的移動軌跡是否蛇行、大幅左右偏移及急加速、急減速等，語意分析技術及物件偵測技術並非本發明之重點，故在此不加以贅述。 It is worth noting that in this embodiment, the at least one specific condition includes the processing module 16 receiving a control input signal generated by a driver's input operation on the user input and output interface 15, the image capture The movement trajectory of the detected object in one of the current images captured by the module 13 at the current time point changes abnormally, the movement speed of the detected object in the current image captured by the image capturing module 13 is abnormal, and the sense of gravity The sensing value sensed by one of the sensing modules 17 at the current point in time is greater than a threshold, but is not limited to this. When the user input interface 15 generates the control input signal, it means that the driver It is considered that there is a need for recording, so the user input and output interface 15 is operated; when the movement trajectory or movement speed of the detected object in the current image is abnormal, it means that an accident has occurred in another vehicle; when the sensing value is greater than the threshold, Indicates that the vehicle may have been involved in a collision. Among them, the processing module 16 uses the object detection technology in image recognition to determine whether the movement trajectory of the detected object is snaking, deviating significantly from left to right. Moving, rapid acceleration, rapid deceleration, etc., semantic analysis technology and object detection technology are not the focus of the present invention, so they will not be described again here.

舉例來說，當特定條件數量為一，該特定條件例如為該處理模組16接收到該控制輸入訊號時，該駕駛人發現有事件(例如口角衝突、車禍、交通違規)，操作該使用者輸入輸出介面15產生該控制輸入訊號，以控制該處理模組16進行步驟302。當特定條件數量為複數，該等特定條件例如為該當前影像之該偵測物件的移動軌跡，以及該當前影像之該偵測物件的移動速度，則該處理模組16根據該當前影像之該偵測物件的移動軌跡是否異常且該偵測物件的移動速度是否異常，以判定是否進行步驟302。 For example, when the number of specific conditions is one, the specific condition is, for example, when the processing module 16 receives the control input signal and the driver discovers an event (such as a verbal conflict, a car accident, a traffic violation), and operates the user The input-output interface 15 generates the control input signal to control the processing module 16 to perform step 302. When the number of specific conditions is plural, such as the moving trajectory of the detected object in the current image and the moving speed of the detected object in the current image, the processing module 16 will Whether the movement trajectory of the detected object is abnormal and whether the movement speed of the detected object is abnormal is determined to determine whether to proceed to step 302.

It is worth noting that this sensitive information includes, but is not limited to, personal health information, personal company salary and bonus, personal residence, and even personal private life and other related content. In this embodiment, the processing module 16 determines whether the vocal signals of the vocal signal group include key words related to the above-mentioned related content, such as blood pressure, blood sugar, monthly salary, address and other key words, to determine whether the vocal signals Whether the sensitive information is included in the group, but not limited to this.

當該處理模組16判定出該人聲訊號組具有該機敏資料時，流程進行步驟303；而當該處理模組16判定出該人聲訊號組不具有該機敏資料時，則流程進行步驟304。 When the processing module 16 determines that the vocal signal group has the alert data, the process proceeds to step 303; and when the processing module 16 determines that the vocal signal group does not When the sensitive information is available, the process proceeds to step 304.

If the vocal signal group is marked with the smart stamp, the smart stamp still exists in the vocal signal after cutting. in the fragment file corresponding to the group, but not limited to this.

在步驟305中，該獨立安全晶片模組18將該等碎片檔案進行編號，以產生多個分別對應該等碎片檔案的安全編號。 In step 305, the independent security chip module 18 numbers the fragmented files to generate a plurality of security numbers respectively corresponding to the fragmented files.

在步驟306中，該處理模組16經由該通訊模組12廣播一短距分散式儲存需求至該短距離無線通訊發射範圍內。 In step 306, the processing module 16 broadcasts a short-range distributed storage request to the short-range wireless communication transmission range through the communication module 12.

在步驟307中，在該處理模組16經由該通訊模組12接收到多個分別來自多個電子裝置2的短距分散式儲存鏈接應答後，該處理模組16判定該等短距分散式儲存鏈接應答的數量是否大於一預設值，其中，每一短距分散式儲存鏈接應答包括一裝置識別資訊，該裝置識別資訊例如包括一電子裝置名稱、一媒體存取控制位址(MAC Address)、一會員註冊名稱、一相關於當前所在位置的GPS資訊，及一裝置識別資訊產生時間，但不以此為限。當該處理模組16判定出該等短距分散式儲存鏈接應答的數量大於該預設值時，流程進行步驟308；而當該處理模組16該等短距分散式儲存鏈接應答的數量不大於該預設值時，則流程進行步驟314。 In step 307, after the processing module 16 receives a plurality of short-range distributed storage link responses from a plurality of electronic devices 2 via the communication module 12, the processing module 16 determines that the short-range distributed storage link responses are Whether the number of stored link replies is greater than one Default value, wherein each short-distance distributed storage link response includes a device identification information. The device identification information includes, for example, an electronic device name, a media access control address (MAC Address), a member registration name, a GPS information related to the current location, and the time when a device identification information was generated, but is not limited to this. When the processing module 16 determines that the number of short-range distributed storage link responses is greater than the preset value, the process proceeds to step 308; and when the processing module 16 determines that the number of short-range distributed storage link responses is not When it is greater than the preset value, the process proceeds to step 314.
