Description
本發明涉及視頻資料傳輸領域，尤其涉及一種實現USB設備檢測的USB Type-C轉接器及其通道控制方法。 The present invention relates to the field of video data transmission, and in particular to a USB Type-C adapter for implementing USB device detection and a channel control method thereof.
USB Type-C介面具有更快傳送速率、更強電力傳輸能力以及支援雙面插接等特點，是目前電子設備介面的一個主流選擇，越來越多的電子設備上都配備了USB Type-C介面。 The USB Type-C interface features fast transfer rate, enhanced power transfer capability, and support for double-sided plug-in. It is currently a mainstream choice for electronic device interfaces. More and more electronic devices are equipped with USB Type-C. interface.
USB Type-C轉接器將USB Type-C的介面轉換為其他視訊訊號的介面，同時還具有USB介面，視訊訊號介面例如DP(Display Port)、VGA(Video Graphics Array)或HDMI(High Definition Multimedia Interface，高清晰度多媒體介面)介面等，這樣，可以將源設備上的多媒體資料藉由傳統的視訊訊號介面輸出到顯示裝置上，同時還可以用於資料的傳輸。 The USB Type-C adapter converts the USB Type-C interface to other video signal interfaces, and also has a USB interface.

USB Type-C有四對高速差分對資料通道，USB3.x資料以及視頻資料共用這些資料通道進行傳輸，目前，在USB Type-C轉接器應用中，資料通道的分配是在系統組態初始化時固定下來的，無法根據不同的應用情景來重新分配資料通道，例如資料通道的具體分配方式為：當傳輸視頻資料時，所有資料通道用於視頻的傳輸；當傳輸USB3.x資料時，所有資料通道用於USB3.x資料的傳輸，這無法滿足同時傳輸USB3.x資料和視頻資料的需求；而當資料通道的具體分配方式為：將其中一些資料通道用於USB3.x資料的傳輸，將另外一些資料通道用於視頻資料的傳輸，這樣，可以滿足同時傳輸USB3.x資料和視頻資料的需求，但在僅需傳輸視頻資料時，仍然還有部分的資料通道進行傳輸，部分通道的傳輸會降低視頻傳輸的解析度，影響 視頻品質。這樣，一旦確定了通道的應用方式，傳輸方式就被固定下來，無法根據轉接器的使用狀態來確定相應的傳輸方式，這種方式無法滿足使用者對轉接器的功能多樣化和靈活性的需求。 USB Type-C has four pairs of high-speed differential pair data channels. USB3.x data and video data share these data channels for transmission. Currently, in USB Type-C adapter applications, data channel allocation is initialized in the system configuration. When fixed, it is not possible to redistribute data channels according to different application scenarios. For example, the specific allocation of data channels is: when transmitting video data, all data channels are used for video transmission; when transferring USB3.x data, all The data channel is used for the transmission of USB3.x data, which cannot meet the requirement of simultaneously transmitting USB3.x data and video data; and when the data channel is specifically allocated, some of the data channels are used for the transmission of USB3.x data. Other data channels are used for the transmission of video data, so that the requirements for simultaneously transmitting USB3.x data and video data can be satisfied, but when only video data needs to be transmitted, there are still some data channels for transmission, and some channels are Transmission will reduce the resolution of video transmission, affecting Video quality. In this way, once the application mode of the channel is determined, the transmission mode is fixed, and the corresponding transmission mode cannot be determined according to the state of use of the adapter, which cannot satisfy the user's function diversification and flexibility of the adapter. Demand.

參考圖2所示，其中圖(A)為USB3.X的連接器的針腳分佈結構示意圖，USB3.X的連接器同時還相容USB2.0資料的連接，當用於USB2.0資料的連接時，僅第一針腳至第四針腳被佔用，第五針腳至第九針腳為懸空，當用於USB3.X資料的連接時，所有的針腳被佔用。 Referring to Figure 2, Figure (A) is a schematic diagram of the pin distribution structure of the connector of USB3.X, and the connector of USB3.X is also compatible with the connection of USB2.0 data, when used for connection of USB2.0 data. Only the first to fourth pins are occupied, and the fifth to ninth pins are left floating. When used for connection of USB3.X data, all the pins are occupied.
USB3.X的連接器中有三個接地信號，分別為第七針腳GND_DRAIN、 第四針腳GND和連接器的殼體SHELL。在一些實施例中，在當轉接器的USB3.X的連接器僅用於USB3.X資料的連接時，其中第四針腳GND為常地端，這三個接地信號中的第七針腳GND_DRAIN和連接器的殼體SHELL可以用於確定第一連接器的狀態信號的第一接地信號，也就是說，第一接地信號可以為第七針腳GND_DRAIN和連接器的殼體SHELL的接地信號中的任意一個。第一接地信號為獨立信號，即該信號並不與其他的接地信號短接，僅為一個獨立的信號，這樣僅在有設備掛載時，才會被置為接地信號。參考圖2中(B)所示，圖(B)為有USB3.X設備掛載時的第一連接器的連接狀態示意圖，由於第一接地信號為獨立信號，只有在有USB3.X設備掛載時，第一接地信號才被置為地信號，而沒有USB3.X設備掛載時，第一接地信號則被置為非地信號。因此，藉由該信號可以判斷第一連接器是否被掛載的狀態信號，進而，藉由該狀態信號來確定是否重新分配資料通道。 There are three ground signals in the connector of USB3.X, which are the seventh pin GND_DRAIN, The fourth pin GND and the housing of the connector SHELL. In some embodiments, when the connector of the USB 3.X of the adapter is only used for the connection of the USB 3.X data, wherein the fourth pin GND is the normal ground, the seventh pin of the three ground signals GND_DRAIN And the housing SHELL of the connector can be used to determine the first ground signal of the state signal of the first connector, that is, the first ground signal can be in the ground signal of the seventh pin GND_DRAIN and the housing SHELL of the connector anyone. The first ground signal is an independent signal, that is, the signal is not short-circuited with other ground signals, and is only an independent signal, so that it is only grounded when the device is mounted. Referring to FIG. 2(B), FIG. (B) is a schematic diagram showing the connection state of the first connector when the USB3.X device is mounted. Since the first ground signal is an independent signal, only the USB3.X device is hung. At the time of loading, the first ground signal is set to the ground signal, and when no USB3.X device is mounted, the first ground signal is set to the non-ground signal. Therefore, the signal can be used to determine whether the first connector is mounted or not, and further, the status signal determines whether to re-allocate the data channel.
在另一些實施例中，轉接器的USB3.X的連接器400既用於USB3.X資料的連接又用於USB2.0資料的連接時，第一連接器400上掛載的設備可能是USB2.0設備或者USB3.X設備，而USB2.0設備藉由D+/D-資料通道傳輸資料，無需與視頻傳輸共用資料通道，僅當掛載為USB3.X設備時，需要與視頻傳輸共用資料通道，因此，當第一連接器400有被掛載時，需要判斷出是USB2.0設備還是USB3.X設備掛載。參考圖2中(B)、(C)所示，第七針腳GND_DRAIN僅在USB3.X設備掛載時被佔用，在當USB2.0設備掛載時為懸空，則，在第一連接器狀態確定模組中，可以確定兩個接地信號，第一接地信號為第七針腳GND_DRAIN的接地信號，第二接地信號為第一連接器殼體SHELL的接地信號，這兩個接地信號都為獨立信號，即不與其他常地信號短接，這樣，當第一接地信號和第二接地信號都為地信號時，則表示為USB3.X設備掛載，當第二接地信號為地信號而第一接地信號為非地信號時，則表示為USB2.0設備掛載，當第一接地信號和第二接地信號都為非地信號時，則表示無USB設備掛載。這樣，藉由識別這兩個接地信號，就可以確定出第一連接器的狀態信號，該狀態信號指是否被USB3.X設備掛載以及是否被USB2.0設備掛載。 In other embodiments, when the USB 3.X connector 400 of the adapter is used for both USB 3.X data connection and USB 2.0 data connection, the device mounted on the first connector 400 may be USB2.0 device or USB3.X device, while USB2.0 device transmits data through D+/D- data channel, no need to share data channel with video transmission, only need to share with video transmission when mounting as USB3.X device The data channel, therefore, when the first connector 400 is mounted, it is necessary to determine whether the USB 2.0 device or the USB 3.X device is mounted. Referring to (B) and (C) of FIG. 2, the seventh pin GND_DRAIN is occupied only when the USB 3.X device is mounted, and is suspended when the USB 2.0 device is mounted, then in the first connector state. In the determining module, two grounding signals can be determined, the first grounding signal is the grounding signal of the seventh pin GND_DRAIN, and the second grounding signal is the grounding signal of the first connector housing SHELL, and the two grounding signals are independent signals That is, it is not short-circuited with other permanent signals, so that when both the first ground signal and the second ground signal are ground signals, it is indicated that the USB3.X device is mounted, and when the second ground signal is a ground signal, the first When the ground signal is a non-ground signal, it indicates that the USB2.0 device is mounted. When both the first ground signal and the second ground signal are non-ground signals, it means that no USB device is mounted. Thus, by identifying the two ground signals, it is possible to determine the status signal of the first connector, whether the status signal is mounted by the USB 3.X device and whether it is mounted by the USB 2.0 device.
在本發明優選實施例中，第一連接器狀態確定模組為包括比較器的電路模組，藉由比較器來獲取並輸出連接器的狀態資訊。參考圖3所示，第一 連接器狀態確定模組包括第一比較器501A，用於獲取和輸出第一接地信號，還可以進一步包括第二比較器501B，用於獲取和輸出第二接地信號。 In a preferred embodiment of the present invention, the first connector state determining module is a circuit module including a comparator, and the comparator obtains and outputs state information of the connector.

In the specific embodiment, the first reference voltage VREF1 is connected to the positive input terminal of the first comparator 501A, and the first ground signal and the first pull-up resistor Ru1 are connected to the negative input terminal of the first comparator 501A, without USB3. When the X device is mounted, the negative input terminal is held by the pull-up resistor Ru1 to maintain the voltage of the terminal at the voltage VCC1 of the first power supply. Since the first power supply VCC1 is greater than the reference voltage VREF1, the first comparator VREF1 outputs U3CON to 0. When a USB3.X device is mounted, the first ground signal is grounded, the negative input terminal is pulled down to the ground voltage by the ground signal, and the reference voltage is a non-ground voltage, which is greater than the ground voltage. At this time, the first comparator output U3CON is 1. In this particular example, the first ground signal is the signal of the seventh pin GND_DRAIN.
第二比較器501B的一輸入端連接第二參考電壓VREF2，另一輸入端連接至第二接地信號、以及藉由第二上拉電阻Ru2連接至第二電源VCC2，所述第二電源VCC2的電壓大於所述第二參考電壓VREF2。同第一比較器，在該具體的實施例中，第二參考電壓連接第二比較器501B的正輸入端，第二接地信號及第二上拉電阻Ru2連接第二比較器501B的負輸入端，在沒有USB2.0或USB3.X設備掛載時，負輸入端被上拉電阻Ru2將該端的電壓保持在第二電源的電壓VCC2，由於第二電源VCC2大於第二參考電壓VREF2，此時，第二比較器輸出UXCON為0，而當有USB2.0設備或USB3.X設備掛載時，第二接地信號被接地，負輸入端被接地信號下拉至接地電壓，參考電壓為非接地電壓，大於接地電壓，此時，第二比較器輸出UXCON為1。在該具體的示例中，第二接地信號為連接器殼體SHELL的信號。 An input terminal of the second comparator 501B is connected to the second reference voltage VREF2, the other input terminal is connected to the second ground signal, and is connected to the second power source VCC2 by the second pull-up resistor Ru2, the second power source VCC2 The voltage is greater than the second reference voltage VREF2. With the first comparator, in the specific embodiment, the second reference voltage is connected to the positive input terminal of the second comparator 501B, and the second ground signal and the second pull-up resistor Ru2 are connected to the negative input terminal of the second comparator 501B. When no USB2.0 or USB3.X device is mounted, the negative input terminal is held by the pull-up resistor Ru2 to maintain the voltage of the terminal at the voltage VCC2 of the second power supply. Since the second power supply VCC2 is greater than the second reference voltage VREF2, The second comparator output UXCON is 0. When a USB 2.0 device or a USB 3.X device is mounted, the second ground signal is grounded, the negative input terminal is pulled down to the ground voltage by the ground signal, and the reference voltage is a non-ground voltage. , greater than the ground voltage, at this time, the second comparator output UXCON is 1. In this particular example, the second ground signal is a signal to the connector housing SHELL.
在當第一連接器僅用於USB3.X資料的連接時，藉由第一比較器就可以獲取並輸出USB3.X設備掛載是否掛載的狀態資訊，在上述具體的示例中，第一比較器的輸出U3CON為1時，表示第一連接器被USB3.X設備，U3CON為0時，為沒有USB3.X設備掛載；而當第一連接器用於USB3.X資料和USB2.0資料的連接時，藉由第一比較器和第二比較器獲取並輸出是否被USB3.X設備掛載以及是否被USB2.0設備掛載的狀態信號，在上述具體的示 例中，當第一比較器的輸出U3CON為1且第二比較器的輸出UXCON為1時，表示第一連接器400被USB3.X設備掛載，當第一比較器的輸出U3CON為0且第二比較器的輸出UXCON為1時，表示第一連接器400被USB2.0設備掛載，當第一比較器的輸出U3CON為0且第二比較器的輸出UXCON為0時，表示第一連接器400沒有被掛載。 When the first connector is only used for the connection of the USB 3.X data, the first comparator can acquire and output the status information of whether the USB 3.X device is mounted or not. In the above specific example, the first When the output of the comparator U3CON is 1, it means that the first connector is USB3.X device, U3CON is 0, no USB3.X device is mounted; and when the first connector is used for USB3.X data and USB2.0 data When the connection is made, the first comparator and the second comparator acquire and output a status signal whether it is mounted by the USB 3.X device and is mounted by the USB 2.0 device, in the above specific In the example, when the output U3CON of the first comparator is 1 and the output UXCON of the second comparator is 1, it indicates that the first connector 400 is mounted by the USB 3.X device, and when the output of the first comparator U3CON is 0 and When the output UXCON of the second comparator is 1, it indicates that the first connector 400 is mounted by the USB 2.0 device. When the output of the first comparator U3CON is 0 and the output UXCON of the second comparator is 0, it indicates the first The connector 400 is not mounted.
由於可以獲得第一連接器是否被USB3.X設備掛載的狀態信號，那麼，可以根據該狀態信號，來進一步控制資料傳輸通道的控制，以滿足不同的需要，在具體的通道控制中，可以藉由即時獲取上述的狀態信號，當狀態信號表示為USB3.X設備掛載時，繼續判斷四對差分對資料通道是否被佔用，若是，則表示此時正在進行視頻資料的傳輸，則，重新進行資料通道的分配，使得所述四對差分對資料通道中的一部分用於傳輸USB3.X資料、另一部分用於繼續傳輸視頻資料。具體的，可以藉由USB-PD/AUX通信的方式告知資料來源設備降低視頻解析度，使用其中的兩對差分數據通道進行視頻資料的傳輸，而將另外兩對差分數據通道用於USB3.X資料的傳輸，而後，以低解析度的方式以兩條資料通道傳輸視頻資料，另兩條資料通道同時傳輸USB3.X數據。 Since the status signal of whether the first connector is mounted by the USB 3.X device can be obtained, the control of the data transmission channel can be further controlled according to the status signal to meet different needs, and in specific channel control, By acquiring the above status signal in real time, when the status signal is indicated as being mounted by the USB 3.X device, it is determined whether the four pairs of differential pair data channels are occupied, and if so, it indicates that the video data transmission is being performed at this time, then, The data channel is allocated such that a portion of the four pairs of differential pair data channels are used to transmit USB 3.X data and another portion is used to continue to transmit video material. Specifically, the data source device can be notified by the USB-PD/AUX communication method to reduce the video resolution, and the two pairs of differential data channels are used for video data transmission, and the other two pairs of differential data channels are used for USB 3.X. The data is transmitted, and then the video data is transmitted in two data channels in a low resolution manner, and the other two data channels simultaneously transmit USB 3.X data.
在整個傳輸中，持續獲取狀態信號，當狀態信號改變時，當所述狀態信號表示由USB3.X設備掛載轉變為非掛載時，則表示此時USB3.X資料傳輸已結束，則，重新進行資料通道的分配，使得所述四對差分對資料通道都用於傳輸視頻資料。具體地，可以藉由USB-PD/AUX通信的方式告知資料來源設備重新以高解析度的方式進行視頻傳輸，重新使用四對差分對資料通道用於視頻資料傳輸。 During the entire transmission, the status signal is continuously acquired. When the status signal changes, when the status signal indicates that the USB3.X device is mounted to be unmounted, it indicates that the USB3.X data transmission has ended. The data channel is re-allocated such that the four pairs of differential pair data channels are used to transmit video data. Specifically, the data source device can be notified by the USB-PD/AUX communication to perform video transmission in a high-resolution manner, and the four pairs of differential pair data channels are reused for video data transmission.
