Description
本發明涉及一種資料傳輸測試設備及資料傳輸測試方法。 The invention relates to a data transmission test device and a data transmission test method.
近些年來，個人電腦、數位相機、數位攝像機及便攜式音/視頻播放器等電子設備廣泛地應用到人們的日常生活工作中，這些電子設備之間通常需要交換資料。例如，將數位攝像機拍攝的視頻圖像傳入電腦通常使用火線介面(即IEEE 1394介面，Institute of Electrical and Electronics Engineers)，將個人電腦中的MP3音樂等文件存入便攜式音/視頻播放器等設備則通常使用USB(Universal Serial Bus，通用串列匯流排)介面。 In recent years, electronic devices such as personal computers, digital cameras, digital video cameras, and portable audio/video players have been widely used in people's daily work, and these electronic devices usually need to exchange data. For example, transferring a video image taken by a digital camera to a computer usually uses a FireWire interface (IEEE 1394 interface, Institute of Electrical and Electronics Engineers) to store files such as MP3 music on a personal computer into a portable audio/video player. A USB (Universal Serial Bus) interface is usually used.
通常，使用IEEE 1394、USB等資料傳輸介面時最關心的問題是資料的傳輸速度。例如，將大量音/視頻文件從個人電腦傳入便攜式音/視頻播放器時，若資料的傳輸速度太慢，將會耗費大量的時間。IEEE 1394、USB等介面的傳輸速度都在較快發展以減少資料傳輸過程的等待時間。例如，早期的USB 1.1全速狀態下的理論最大傳輸速度是12Mbps，而目前已廣泛應用的USB 2.0高速狀態下的理論最大傳輸速度可達480Mbps。另外，1394a與1394b兩種標準的傳輸速度分別為400Mbps與800Mbps。 Usually, the most important issue when using the data transmission interface such as IEEE 1394 or USB is the data transmission speed. For example, when a large number of audio/video files are transferred from a personal computer to a portable audio/video player, it takes a lot of time if the data is transmitted too slowly. The transmission speeds of IEEE 1394, USB and other interfaces are developing rapidly to reduce the waiting time of the data transmission process. For example, the theoretical maximum transmission speed of the early USB 1.1 full speed state was 12 Mbps, and the theoretical maximum transmission speed of the widely used USB 2.0 high speed state can reach 480 Mbps. In addition, the transmission speeds of the 1394a and 1394b standards are 400 Mbps and 800 Mbps, respectively.
雖然IEEE 1394、USB等資料傳輸介面在設計時各自的理論最大傳輸速度值相同，然而在實際使用過程中，受控 制晶片、傳輸線路及使用的電磁環境等影響，資料的實際傳輸速度並不相同，部分產品的傳輸速度較低甚至完全不能傳輸資料。因此，在產品出售之前必須對IEEE 1394、USB等資料傳輸介面進行測試，將傳輸速度較低及完全不能傳輸資料的產品剔除。 Although the data transmission interfaces such as IEEE 1394 and USB are designed to have the same theoretical maximum transmission speed value, they are controlled during actual use. The actual transmission speed of the data is not the same due to the influence of the chip, the transmission line and the electromagnetic environment used. Some products have a low transmission speed or cannot transmit data at all. Therefore, before the product is sold, the data transmission interface such as IEEE 1394 and USB must be tested to eliminate the products with low transmission speed and no data transmission at all.
傳統的資料傳輸介面測試方法是利用存儲設備實現的。存儲設備採用與資料傳輸介面相應的測試介面與資料傳輸介面相連，藉由系統自動執行複製、粘貼等操作，判斷目標文件在限定時間內能否從主機傳輸到存儲設備。若在限定時間內未能傳輸完畢或傳輸失敗，則表示該資料傳輸介面不合格。 The traditional data transmission interface test method is implemented by using a storage device. The storage device is connected to the data transmission interface by using a test interface corresponding to the data transmission interface, and the system automatically performs copying and pasting operations to determine whether the target file can be transferred from the host to the storage device within a limited time. If the transmission fails within the limited time or the transmission fails, the data transmission interface is unqualified.
資料傳輸介面性能除傳輸速度外，還需考慮其傳輸的穩定性，即資料傳輸過程不出現傳輸速度波動過大的情況。特別是在大量資料需要傳輸的時候，資料傳輸的穩定性就顯得尤為重要，若傳輸不穩定，可能導致傳輸中止甚至失敗。然而，傳統的資料傳輸介面測試方法在測試過程中不能用於測試穩定性，只能判斷在限定時間內能否傳輸限定量的資料，即只能測試平均傳輸速度是否能達到預定標準。並且，為保證測試速度，目標文件通常設置得較小，在短時間內資料即可傳輸完畢，無法測試其傳輸穩定性。 In addition to the transmission speed, the data transmission interface performance also needs to consider the stability of its transmission, that is, the data transmission process does not appear to have excessive fluctuations in transmission speed. Especially when a large amount of data needs to be transmitted, the stability of data transmission is particularly important. If the transmission is unstable, the transmission may be suspended or even failed. However, the traditional data transmission interface test method cannot be used for test stability during the test process. It can only judge whether a limited amount of data can be transmitted within a limited time, that is, it can only test whether the average transmission speed can reach a predetermined standard. Moreover, in order to ensure the test speed, the target file is usually set to be small, and the data can be transmitted in a short time, and the transmission stability cannot be tested.
有鑒於此，有必要提供一種用於測試資料傳輸介面的傳輸穩定性的測試設備。 In view of this, it is necessary to provide a test device for testing the transmission stability of the data transmission interface.
此外，還有必要提供一種用於測試資料傳輸介面的傳輸 穩定性的測試方法。 In addition, it is necessary to provide a transmission for testing the data transmission interface. Test method for stability.

上述資料傳輸測試設備及方法，在資料傳輸過程中即時對資料進行分析編碼，並將資料的傳輸速度狀態顯示在顯示裝置上，從而可以對資料傳輸的穩定性進行檢測監控。 The above data transmission test equipment and method can analyze and encode the data in the data transmission process, and display the data transmission speed status on the display device, thereby detecting and monitoring the stability of the data transmission.
如圖1所示，資料傳輸測試設備100用於測試電子設備200的資料傳輸介面210資料傳輸的穩定性，例如個人電腦的USB介面或1394介面等介面的資料傳輸穩定性。資料傳輸測試設備100包括測試介面10、資料擷取模組20、分析模組30、編碼模組40、顯示控制模組50、顯示裝置60、警 示控制模組70及警示器80。 As shown in FIG. 1, the data transmission test device 100 is used to test the stability of data transmission of the data transmission interface 210 of the electronic device 200, such as the data transmission stability of a USB interface or a 1394 interface of a personal computer. The data transmission test device 100 includes a test interface 10, a data capture module 20, an analysis module 30, an encoding module 40, a display control module 50, a display device 60, and a police The control module 70 and the warning device 80 are shown.
測試介面10用於與電子設備200的資料傳輸介面210相連，從而使電子設備200與資料傳輸測試設備100電性連接，以便傳輸測試資料。 The test interface 10 is connected to the data transmission interface 210 of the electronic device 200, so that the electronic device 200 is electrically connected to the data transmission test device 100 for transmitting test data.
資料擷取模組20用於接收測試介面10接收到的資料，將其轉換為資料傳輸測試設備100能識別處理的測試資料。例如，若測試介面10為USB介面，則資料擷取模組20將USB差模訊號轉換為串列訊號。 The data capture module 20 is configured to receive the data received by the test interface 10 and convert it into test data that the data transmission test device 100 can recognize and process. For example, if the test interface 10 is a USB interface, the data capture module 20 converts the USB differential mode signal into a serial signal.
分析模組30用於對資料擷取模組20轉換得出的測試資料進行分析處理。分析模組30識別出串列訊號中的資料包(Packet recognition)後，將時鐘/資料訊號分離(Clock/Data separation)，並將分離得出的串列資料轉換成並行資料(Serial Parallel Conversion)。 The analysis module 30 is configured to analyze and process the test data converted by the data capture module 20. After the analysis module 30 recognizes the packet identification in the serial signal, it separates the clock/data separation and converts the separated serial data into parallel data (Serial Parallel Conversion). .
編碼模組40用於根據轉換的並行資料編碼產生輸出資料。例如，輸出資料可以設為8位元二進位資料，對應的將資料傳輸速度分為8個等級。當資料傳輸速度為某一等級時，將輸出資料的相應的二進位位元設為1，其餘則設為0。 The encoding module 40 is configured to generate output data according to the converted parallel data encoding. For example, the output data can be set to 8-bit binary data, and the corresponding data transmission speed is divided into 8 levels. When the data transmission speed is a certain level, the corresponding binary bit of the output data is set to 1, and the rest is set to 0.
顯示控制模組50用於根據輸出資料控制顯示裝置60顯示測試介面10中資料的傳輸速度。例如，當上述8位元二進位資料的某個二進位位元為1時，則顯示控制模組50控制顯示裝置60的相應位置的發光二極體(Light Emitting Diode，LED)發光。 The display control module 50 is configured to control the display device 60 to display the transmission speed of the data in the test interface 10 according to the output data. For example, when a certain binary bit of the 8-bit binary data is 1, the display control module 50 controls the light emitting diode (LED) of the corresponding position of the display device 60 to emit light.
警示控制模組70用於根據輸出資料控制警示器80。當資 料流程量低於預定值，警示控制模組70發出控制訊號至警示器80，使警示器80發出報警資訊。例如，當被設為1的二進位位元位於上述8位元二進位資料的低四位元時，警示控制模組70啟動警示器80報警。警示器80可以是蜂鳴器等發聲設備或LED發光器件等。 The alert control module 70 is configured to control the alerter 80 based on the output data. Capital The amount of material flow is lower than the predetermined value, and the warning control module 70 sends a control signal to the warning device 80 to cause the warning device 80 to send an alarm message. For example, when the binary bit set to 1 is located at the lower four bits of the 8-bit binary data, the alert control module 70 activates the alert 80 to alert. The alerter 80 may be a sounding device such as a buzzer or an LED light emitting device or the like.
如圖2所示，其為測試介面10為USB介面時資料傳輸測試設備100的示意圖。由於通用串列匯流排(USB)介面的廣泛使用，不少電子設備設有多個USB介面，例如，個人電腦等。 As shown in FIG. 2, it is a schematic diagram of the data transmission test apparatus 100 when the test interface 10 is a USB interface. Due to the widespread use of the universal serial bus (USB) interface, many electronic devices have multiple USB interfaces, such as personal computers.
測試介面10包括8個USB介面，編號依次為USB0~USB7。顯示裝置60包括與該8個USB介面對應的8個顯示設備，每一顯示設備顯示相應USB介面的資料傳輸狀態。顯示設備可以採用8個LED發光元件，資料傳輸速率較高則高位(圖2中左邊)的LED發光，資料傳輸速率較低則低位元的LED發光。以下以USB2及USB3為例說明，藉由USB2及USB3接收的資料依次經資料擷取模組20、分析模組30處理後傳輸至編碼模組40，編碼模組40採用輪詢的方式分別將USB2及USB3的資料傳輸狀態藉由顯示控制模組50顯示在第一顯示設備62及第二顯示設備64上。例如，USB2的資料傳輸率穩定在較高的水平上，則第一顯示設備62的高位LED發光；而USB3的資料傳輸率較低，則第二顯示設備64的低位元LED發光，並且警示控制模組70發出控制訊號至警示器80，使警示器80發出報警資訊。另外，顯示設備的LED也可以設置成兩個以上的其他數量，例如4個或6個等。若資料傳輸不穩定，例如傳輸速度時高時低 ，則顯示控制模組50控制不同的LED依次亮起，從而出現閃爍的效果以表示資料傳輸不穩定。 The test interface 10 includes eight USB interfaces, numbered sequentially from USB0 to USB7. The display device 60 includes eight display devices corresponding to the eight USB interfaces, and each display device displays a data transmission status of the corresponding USB interface. The display device can adopt 8 LED light-emitting elements. When the data transmission rate is high, the high-level LED (the left side in FIG. 2) emits light, and the data transmission rate is low, and the low-level LED emits light. The following takes USB2 and USB3 as an example. The data received by USB2 and USB3 is processed by the data capture module 20 and the analysis module 30, and then transmitted to the encoding module 40. The encoding module 40 uses polling methods respectively. The data transfer status of USB2 and USB3 is displayed on the first display device 62 and the second display device 64 by the display control module 50. For example, if the data transmission rate of the USB2 is stable at a higher level, the high-order LED of the first display device 62 emits light; and the data transmission rate of the USB3 is lower, the low-order LED of the second display device 64 emits light, and the warning control is performed. The module 70 sends a control signal to the alerter 80 to cause the alerter 80 to send an alarm message. In addition, the LED of the display device may also be set to two or more other numbers, for example, four or six. If the data transmission is unstable, for example, the transmission speed is high and low. Then, the display control module 50 controls different LEDs to light up in sequence, so that a flickering effect occurs to indicate that the data transmission is unstable.
如圖3所示，其為測試介面10為火線(1394)介面時資料傳輸測試設備100的示意圖。藉由1394介面16接收的資料依次經資料擷取模組20、分析模組30處理後傳輸至編碼模組40，編碼模組40將1394介面16的資料傳輸狀態藉由顯示控制模組50顯示在數位顯示設備66上。數位顯示設備66可以採用多個七段顯示器或液晶顯示器等，數位顯示設備66可以以數位的方式顯示資料傳輸的速度。若資料的傳輸速度不穩定，則顯示控制模組50控制數字顯示設備66的顯示數位發生變化。當高位的數位發生變化時，表示資料的傳輸不穩定的狀況比較嚴重。若1394介面的資料傳輸速度小於預定值，則警示控制模組70發出控制訊號至警示器80，使警示器80發出報警資訊。 As shown in FIG. 3, it is a schematic diagram of the data transmission test apparatus 100 when the test interface 10 is a FireWire (1394) interface. The data received by the 1394 interface 16 is processed by the data capture module 20 and the analysis module 30 and transmitted to the encoding module 40. The encoding module 40 displays the data transmission status of the 1394 interface 16 through the display control module 50. On the digital display device 66. The digital display device 66 can employ a plurality of seven-segment displays or liquid crystal displays, etc., and the digital display device 66 can display the speed of data transfer in a digital manner. If the transmission speed of the data is unstable, the display control module 50 controls the display digit of the digital display device 66 to change. When the digit of the high digit changes, it indicates that the transmission of the data is unstable. If the data transmission speed of the 1394 interface is less than the predetermined value, the alert control module 70 sends a control signal to the alerter 80 to cause the alerter 80 to send an alarm message.
上述資料傳輸測試設備，在資料傳輸過程中即時對資料進行分析編碼，並將資料的傳輸速度狀態顯示在顯示裝置上，從而可以對資料傳輸的穩定性進行檢測監控。 The above data transmission test equipment analyzes and encodes the data in the data transmission process, and displays the data transmission speed status on the display device, so that the stability of the data transmission can be detected and monitored.
如圖4所示，其為一較佳實施方式的資料傳輸測試方法流程圖。 As shown in FIG. 4, it is a flowchart of a data transmission test method according to a preferred embodiment.
首先，步驟402，擷取測試介面10接收到的資料，將接收到的資料轉換為資料傳輸測試設備100能識別處理的資料。例如，若測試介面10為USB介面，則資料擷取模組20將USB差模訊號轉換為串列訊號。 First, in step 402, the data received by the test interface 10 is retrieved, and the received data is converted into data that the data transmission test device 100 can recognize. For example, if the test interface 10 is a USB interface, the data capture module 20 converts the USB differential mode signal into a serial signal.
步驟404，將轉換得出的串列訊號資料進行分析處理。先 識別出串列訊號中的資料包(Packet recognition)後，將時鐘/資料訊號分離(Clock/Data separation)，並將分離得出的串列資料轉換成並行資料(Serial Parallel Conversion)。 Step 404: Perform analysis processing on the converted serial signal data. first After identifying the packet identification in the serial signal, the clock/data separation is separated, and the separated serial data is converted into parallel data (Serial Parallel Conversion).
步驟406，根據轉換的並行資料編碼產生輸出資料。例如，輸出資料可以設為8位元二進位資料，對應的將資料傳輸速度分為8個等級。當資料傳輸速度為某一等級時，將輸出資料的相應的二進位位元設為1，其餘則設為0。 Step 406: Generate output data according to the converted parallel data encoding. For example, the output data can be set to 8-bit binary data, and the corresponding data transmission speed is divided into 8 levels. When the data transmission speed is a certain level, the corresponding binary bit of the output data is set to 1, and the rest is set to 0.
步驟408，根據輸出資料顯示，以體現出資料傳輸速度的大小及穩定性。例如，當上述8位元二進位資料的某個二進位位元為1時，則顯示控制模組50控制顯示裝置60的相應位置的發光二極體(Light Emitting Diode，LED)發光。 Step 408, according to the output data display, to reflect the size and stability of the data transmission speed. For example, when a certain binary bit of the 8-bit binary data is 1, the display control module 50 controls the light emitting diode (LED) of the corresponding position of the display device 60 to emit light.
步驟410，判斷輸出資料是否小於預定值。若小於預定值，則發出警示，例如閃爍燈光或發出報警聲音等。若不小於預定值，則返回步驟402。 Step 410: Determine whether the output data is less than a predetermined value. If it is less than the predetermined value, an alert is issued, such as flashing a light or sounding an alarm. If it is not less than the predetermined value, it returns to step 402.
上述資料傳輸測試方法，在資料傳輸過程中即時對資料進行分析編碼，並將資料的傳輸速度狀態顯示出來，從而可以對資料傳輸的穩定性檢測監控。 The above data transmission test method analyzes and encodes the data in the data transmission process, and displays the data transmission speed status, thereby monitoring and monitoring the stability of the data transmission.
