例如:信号处理单元23在检测到特定事件时,发一个OK信号给第二控制单元,第二控制单元26控制第三可控开关25从第三状态切换为第四状态,并发送控制指令至第一控制单元15以由第一控制单元15控制第一可控开关 14从第一状态切换至第二状态。For example: when the signal processing unit 23 detects a specific event, it sends an OK signal to the second control unit, and the second control unit 26 controls the third controllable switch 25 to switch from the third state to the fourth state, and sends a control instruction to The first control unit 15 controls the first controllable switch 14 to switch from the first state to the second state.

在一种可实现的方案中,特定事件可以为串联的第一信号线和第三信号线的信号传输完成事件。串联的第一信号线和第三信号线的信号传输完成事件,可表明串联的第一信号线和第三信号线已完成本次连接过程中传输任务,接下来该串联的第一信号线和第三信号线将会处于空闲状态。因此,可将该串联的第一信号线和第三信号线切换成电源供电线路。In a practicable solution, the specific event may be a signal transmission completion event of the first signal line and the third signal line connected in series. The signal transmission completion event of the first signal line and the third signal line in series can indicate that the first signal line and the third signal line in series have completed the transmission task in this connection process, and then the first signal line in series and the third signal line in series The third signal line will be in an idle state. Therefore, the first signal line and the third signal line connected in series can be switched into power supply lines.

在另一种可实现的方案中,当第一信号线13和第三信号线24均为热插拔检测线路,或者第一信号线和第三信号线均为热插拔检测辅助线路时,特定事件可为多媒体传输通道的建立事件,多媒体传输通道为设备主体通过连接线与外部源设备建立的。In another feasible solution, when both the first signal line 13 and the third signal line 24 are hot-plug detection lines, or the first signal line and the third signal line are both hot-plug detection auxiliary lines, The specific event may be an event of establishing a multimedia transmission channel, and the multimedia transmission channel is established by the main body of the device and an external source device through a connection line.

在一具体电路结构中,连接线1还包括:连接在第一接口11的第二连接点112和第二接口12的第二连接点122之间的第二信号线17以及串联在第二信号线17中的第一集线器18;第一控制单元15与集线器18上的扩展接口连接;设备主体2还包括:第二集线器27;第二控制单元26通过第二集线器27与第三接口22的第二连接点222连接;第二接口12与第三接口22 连接时,第二接口12的第二连接点122与第三接口22的第二连接点222连接,以实现第二控制单元26与第一控制单元15的连接。In a specific circuit structure, the connection line 1 further includes: a second signal line 17 connected between the second connection point 112 of the first interface 11 and the second connection point 122 of the second interface 12 and a second signal line connected in series The first hub 18 in the line 17; the first control unit 15 is connected with the expansion interface on the hub 18; the device main body 2 also includes: a second hub 27; the second control unit 26 connects with the third interface 22 through the second hub 27 The second connection point 222 is connected; when the second interface 12 is connected with the third interface 22, the second connection point 122 of the second interface 12 is connected with the second connection point 222 of the third interface 22, so as to realize the connection between the second control unit 26 and the third interface 22. Connection of the first control unit 15 .

当源设备通过连接线1与设备主体2连接后,因第一集线器18和第二集线器27的设置,不仅不影响连接线中第二信号线原有的信号传输功能外,还能实现连接线1中的第一控制单元15与设备主体2中的第二控制单元26的连接。这样,设备主体2中的第二控制单元26即可与连接线中的第一控制单元15进行通信。When the source device is connected to the device main body 2 through the connecting line 1, due to the setting of the first hub 18 and the second hub 27, not only does not affect the original signal transmission function of the second signal line in the connecting line, but also realizes the connection between the connecting line and the connecting line. The connection between the first control unit 15 in 1 and the second control unit 26 in the main body 2 of the device. In this way, the second control unit 26 in the device main body 2 can communicate with the first control unit 15 in the connection line.

其中,第二信号线17可以为连接线中的USB数据传输线:D+和D-线,即第二信号线17包括两根芯线:D+和D-线,相应的,第一接口11的第二连接点112包括两个引脚D+和D-(如图1所示);第二接口12的第二连接点122也包括两个引脚D+和D-(如图1所示);且第三接口22的第二连接点222也包括两个引脚D+和D-(如图2所示)。设备主体2中的第二控制单元26可通过第二集线器27、第三接口22、第二接口12以及USB数据传输线传输USB2.0信号来通知第一控制单元15,以使第一控制单元15做出相应响应。Wherein, the second signal line 17 can be the USB data transmission line in the connection line: D+ and D- lines, that is, the second signal line 17 includes two core lines: D+ and D- lines, correspondingly, the first interface 11 The second connection point 112 includes two pins D+ and D- (as shown in FIG. 1); the second connection point 122 of the second interface 12 also includes two pins D+ and D- (as shown in FIG. 1); and The second connection point 222 of the third interface 22 also includes two pins D+ and D- (as shown in FIG. 2 ). The second control unit 26 in the device main body 2 can transmit the USB2.0 signal through the second hub 27, the third interface 22, the second interface 12 and the USB data transmission line to notify the first control unit 15, so that the first control unit 15 Respond accordingly.

发明人通过分析发现:一些连接线中通常会包括热插拔检测线(即HPD 信号线),例如:HDMI(High Definition Multimedia Interface,高清多媒体界面)、DP(DisplayPort,显示端口)连接线中都包括HPD信号线。源设备通过热插拔检测线用来检测HPD信号(即一高电平信号),这个HPD信号将作为源设备是否开始传输多媒体数据给设备主体的依据(也即源设备是否与设备主体建立多媒体传输通道的依据)。HPD信号是从待供电设备生成并输出送往源设备的一个检测信号。热插拔检测的作用是当设备主体通过连接线与源设备相连或断开连接时,源设备能够通过接口的HPD引脚检测出这一事件,并做出响应。可见,源设备通过热插拔检测线检测到HPD信号,则可说明待供电设备已连接上,可与供电设备建立起多媒体信号传输通道进行多媒体数据的传输。The inventor has found through analysis that hot plug detection lines (ie HPD signal lines) are usually included in some connecting lines, for example: HDMI (High Definition Multimedia Interface, high-definition multimedia interface), DP (DisplayPort, display port) connecting lines are all Includes HPD signal cable. The source device is used to detect the HPD signal (i.e. a high-level signal) through the hot plug detection line, and this HPD signal will be used as the basis for whether the source device starts to transmit multimedia data to the device body (that is, whether the source device establishes multimedia data with the device body). The basis of the transmission channel). The HPD signal is a detection signal generated from the device to be powered and output to the source device. The function of hot plug detection is that when the main body of the device is connected or disconnected from the source device through the connection line, the source device can detect this event through the HPD pin of the interface and respond. It can be seen that if the source device detects the HPD signal through the hot plug detection line, it can indicate that the power supply device has been connected, and a multimedia signal transmission channel can be established with the power supply device to transmit multimedia data.

此外,有些连接线中还有与热插拔检测线配合使用的热插拔检测辅助线,例如:HDMI连接线中的HDMI_5V信号线。设备主体通过热插拔检测辅助线来检测一辅助信号(即一高电平信号),该辅助信号从源设备生成并输出送往设备主体的一个检测信号,设备主体通过热插拔检测辅助线检测到辅助信号,即可判断出源设备已接入,并生成HPD信号通过热插拔检测线输出送至源设备,以由源设备进行HPD信号的检测。In addition, some cables also have a hot-plug detection auxiliary line used in conjunction with the hot-plug detection line, for example, the HDMI_5V signal line in the HDMI cable. The main body of the device detects an auxiliary signal (that is, a high-level signal) through the hot-plug detection auxiliary line. The auxiliary signal is generated from the source device and outputs a detection signal sent to the main body of the device. When the auxiliary signal is detected, it can be judged that the source device has been connected, and an HPD signal is generated and sent to the source device through the output of the hot plug detection line, so that the source device can detect the HPD signal.

在多媒体数据传输的过程中,连接线中的热插拔检测线以及热插拔检测辅助线并不用于传输多媒体数据,故可在多媒体传输通道建立完成后,将连接线中的热插拔检测线和/或热插拔检测辅助线用来供电。In the process of multimedia data transmission, the hot-swap detection line and hot-swap detection auxiliary line in the connection line are not used to transmit multimedia data, so after the multimedia transmission channel is established, the hot-swap detection line in the connection line line and/or the Hot Plug Detect Auxiliary line for power.

因此,具体实施时,为了不影响现有的连接线中那些用于传输多媒体数据的信号线的工作,上述第一信号线13可具体为热插拔检测线或热插拔检测辅助线。Therefore, in practice, in order not to affect the work of those signal lines used to transmit multimedia data in the existing connection lines, the above-mentioned first signal line 13 may specifically be a hot-plug detection line or a hot-plug detection auxiliary line.

在现有的基于连接线的传输协议中,多媒体传输通道建立起来后,源设备还要继续检测HPD信号,以确保设备主体一直处于连接中;一旦源设备没有检测到HPD信号,则会停止多媒体数据的传输。In the existing connection-based transmission protocol, after the multimedia transmission channel is established, the source device will continue to detect the HPD signal to ensure that the main body of the device is always connected; once the source device does not detect the HPD signal, it will stop the multimedia transmission of data.

当第一信号线和第三信号线均为热插拔检测线时,一旦将第一信号线切换成电源线,第一接口的第一连接点就处于悬置状态,即源设备通过第一接口的第一连接点就无法检测到HPD信号,那么,源设备会按照现有的传输协议,停止多媒体数据的传输,这必然影响了多媒体数据的正常传输。When both the first signal line and the third signal line are hot plug detection lines, once the first signal line is switched to a power line, the first connection point of the first interface is in a suspended state, that is, the source device passes through the first If the first connection point of the interface cannot detect the HPD signal, then the source device will stop the transmission of multimedia data according to the existing transmission protocol, which will inevitably affect the normal transmission of multimedia data.

为了适应现有的传输协议,连接线1还包括:第一电阻20和由第一控制单元15控制的第二可控开关16;第一电阻20和第二可控开关16串联连接在第一接口11的第一连接点110和第一接口11的电源连接点111之间。In order to adapt to the existing transmission protocol, the connection line 1 also includes: a first resistor 20 and a second controllable switch 16 controlled by the first control unit 15; the first resistor 20 and the second controllable switch 16 are connected in series at the first Between the first connection point 110 of the interface 11 and the power connection point 111 of the first interface 11 .

使用时,如图1和图2所示,一旦多媒体传输通道建立之后,第一控制单元15控制第一可控开关14从第一状态(即对应于图中SW1的“1”)切换至第二状态(即对应于图1中SW1中的“2”)的同时,控制第二可控开关16从断开状态(即对应于图中SW3的“2”)切换至闭合状态(即对应于图中SW3的“1”)。这样,第一接口11的第一连接点110就与第一接口 11的电源连接点111连接。第一接口11的电源连接点111是需要给设备主体提供供电电流的,故第一接口11的电源连接点111会一直处于高电平状态。那么,源设备通过第一接口11的第一连接点110能够检测到高电平信号(即 HPD信号),源设备就会继续传输多媒体数据。When in use, as shown in Figures 1 and 2, once the multimedia transmission channel is established, the first control unit 15 controls the first controllable switch 14 to switch from the first state (that is, corresponding to "1" of SW1 in the figure) to the second state. At the same time as the two states (that is, corresponding to "2" in SW1 in Fig. "1" of SW3 in the figure). In this way, the first connection point 110 of the first interface 11 is connected to the power connection point 111 of the first interface 11. The power connection point 111 of the first interface 11 needs to provide power supply current to the main body of the device, so the power connection point 111 of the first interface 11 will always be in a high level state. Then, the source device can detect a high-level signal (that is, the HPD signal) through the first connection point 110 of the first interface 11, and the source device will continue to transmit multimedia data.

此外,在现有的基于连接线的传输协议中,设备主体2中的信号处理单元也需要继续检测辅助信号,以确保源设备一直处于连接状态,一旦信号处理单元检测不到辅助信号,则信号处理单元将会停止输出HPD信号至源设备,这样,源设备也会停止多媒体数据的传输,这必然影响了多媒体数据的正常传输。In addition, in the existing transmission protocol based on the connection line, the signal processing unit in the device body 2 also needs to continue to detect the auxiliary signal to ensure that the source device is always connected. Once the signal processing unit cannot detect the auxiliary signal, the signal The processing unit will stop outputting the HPD signal to the source device, so that the source device will also stop the transmission of multimedia data, which inevitably affects the normal transmission of multimedia data.

当第一信号线和第三信号线均为热插拔检测辅助线时,一旦将第三信号线切换成电源线,信号处理单元的第一连接点就处于悬置状态,即信号处理单元通过其第一连接点就无法检测到辅助信号。信号处理单元无法检测到辅助信号,就会停止向源设备输出HPD信号。那么,源设备会按照现有的传输协议,停止多媒体数据的传输,这必然影响了多媒体数据的正常传输。When both the first signal line and the third signal line are hot plug detection auxiliary lines, once the third signal line is switched to a power line, the first connection point of the signal processing unit is in a suspended state, that is, the signal processing unit passes Its first connection point cannot detect the auxiliary signal. If the signal processing unit fails to detect the auxiliary signal, it stops outputting the HPD signal to the source device. Then, the source device will stop the transmission of multimedia data according to the existing transmission protocol, which will inevitably affect the normal transmission of multimedia data.

为了避免这种情况出现,上述设备主体,还可包括:第四可控开关29 和第二电阻30;所述第四可控开关29和第二电阻30串联连接在所述信号处理单元的第一连接点(如图2所示的HDMI▁5V)与所述电源21的电源连接点211之间;所述第四可控开关29与所述第二控制单元26连接。In order to avoid this situation, the above-mentioned device main body may also include: a fourth controllable switch 29 and a second resistor 30; the fourth controllable switch 29 and the second resistor 30 are connected in series at the first Between a connection point (HDMI 5V as shown in FIG. 2 ) and the power connection point 211 of the power supply 21 ; the fourth controllable switch 29 is connected to the second control unit 26 .

使用时,如图1和图2所示,一旦多媒体传输通道建立之后,第二控制单元26控制第三可控开关25(例如:图2中的SW20)从第三状态(即对应于图中SW20的“1”)切换至第四状态(即对应于图2中SW20中的“2”) 的同时,控制第四可控开关29从断开状态(即对应于图中SW30的“1”) 切换至闭合状态(即对应于图中SW30的“2”)。这样,信号处理单元23 的第一连接点230(例如:图2示出的display IC的HDMI▁5V)就与电源 21的电源连接点211连接。电源21的电源连接点211用来接收源设备提供的供电电流的,故电源21的电源连接点211会一直处于高电平状态。那么,信号处理单元能够通过其第一连接点能够检测到高电平信号(即辅助信号),这样一来,即可确保源设备能继续传输多媒体数据。During use, as shown in Fig. 1 and Fig. 2, once the multimedia transmission channel is established, the second control unit 26 controls the third controllable switch 25 (for example: SW20 in Fig. 2) from the third state (that is, corresponding to "1" of SW20) is switched to the fourth state (that is, corresponding to "2" in SW20 in Fig. ) to switch to the closed state (that is, corresponding to "2" of SW30 in the figure). In this way, the first connection point 230 of the signal processing unit 23 (for example: HDMI 5V of the display IC shown in FIG. 2 ) is connected to the power connection point 211 of the power supply 21 . The power connection point 211 of the power supply 21 is used to receive the power supply current provided by the source device, so the power connection point 211 of the power supply 21 will always be in a high level state. Then, the signal processing unit can detect the high-level signal (ie, the auxiliary signal) through its first connection point, so as to ensure that the source device can continue to transmit multimedia data.

进一步的,上述连接线1中还包括:连接在第一接口11的电源连接点 111和第二接口12的电源连接点121之间的第一电源线19;上述设备主体2 中还包括:连接在第三接口22的电源连接点221和电源21的电源连接点211 之间的第二电源线28;当第二接口12与第三接口22连接时,第二接口12 的电源连接点121和第三接口22的电源连接点221连接,可实现第一电源线 19和第二电源线28的连接(串联)。Further, the connection line 1 also includes: a first power line 19 connected between the power connection point 111 of the first interface 11 and the power connection point 121 of the second interface 12; the above-mentioned device body 2 also includes: The second power line 28 between the power connection point 221 of the third interface 22 and the power connection point 211 of the power supply 21; when the second interface 12 was connected with the third interface 22, the power connection point 121 of the second interface 12 and The power connection point 221 of the third interface 22 is connected to realize the connection (serial connection) of the first power line 19 and the second power line 28 .

当外部源设备通过连接线1与设备主体2连接时,第一信号线13的第一端与第三信号线24的第一端连接;若第一信号线13的第二端连接在第一接口11的电源连接点111上,且第三信号线13的第二端连接在电源21的电源连接点211上,则串联的第一信号线13和第三信号13即与串联的第一电源线19和第二电源线28呈并联设置,连接线上的电阻变小,可降低连接线上的压降和电损耗。When the external source device is connected to the device main body 2 through the connection line 1, the first end of the first signal line 13 is connected to the first end of the third signal line 24; if the second end of the first signal line 13 is connected to the first The power connection point 111 of the interface 11, and the second end of the third signal line 13 is connected to the power connection point 211 of the power supply 21, then the first signal line 13 and the third signal 13 in series are connected to the first power supply in series. The line 19 and the second power supply line 28 are arranged in parallel, the resistance on the connecting line becomes smaller, and the voltage drop and power loss on the connecting line can be reduced.

近几年,随着虚拟现实和增强现实技术的不断发展,头戴显示设备被广泛使用。目前,大部分头戴显示设备需要通过连接线与电脑连接,由电脑供电,并由电脑提供用于播放的多媒体数据。头戴显示设备需通过电脑的USB 接口供电(例如:USB3.0,5V/900mA),且目前头戴显示设备的功耗已接近电脑USB接口的供电极限。为了保证良好的用户体验,用于连接电脑与头戴显示设备的连接线(Cable线)长度又需设置在4m以上。而这样一来,连接线上的电损耗就会很大,易导致头戴显示设备难以达到其运行所需的功耗,影响头戴显示设备的正常工作。采用本实用新型实施例提供的连接线和头戴显示设备,可有效降低连接线上的压降和电损耗。In recent years, with the continuous development of virtual reality and augmented reality technologies, head-mounted display devices have been widely used. At present, most head-mounted display devices need to be connected to a computer through a connection cable, powered by the computer, and provided with multimedia data for playback by the computer. The head-mounted display device needs to be powered by the computer's USB interface (for example: USB3.0, 5V/900mA), and the current power consumption of the head-mounted display device is close to the power supply limit of the computer's USB interface. In order to ensure a good user experience, the length of the cable (cable) used to connect the computer and the head-mounted display device needs to be set to be more than 4m. In this way, the power loss on the connection line will be very large, which will easily cause the head-mounted display device to fail to achieve the power consumption required for its operation, and affect the normal operation of the head-mounted display device. The use of the connecting wire and the head-mounted display device provided by the embodiment of the utility model can effectively reduce the voltage drop and power loss on the connecting wire.

在具体实施时,当多媒体传输通道建立后,可将串联的连接线中的热插拔检测线和待供电设备中的热插拔检测线以及串联的连接线中的热插拔检测辅助线和待供电设备中的热插拔检测辅助线都复用成电源线,以对待供电设备中电源进行充电。越多数量的电源线并联,连接线上的压降就越小,连接线上的电损耗就越少。In specific implementation, after the multimedia transmission channel is established, the hot-swap detection line in the serial connection line and the hot-swap detection line in the equipment to be powered, as well as the hot-swap detection auxiliary line in the series connection line and the The hot plug detection auxiliary lines in the equipment to be powered are multiplexed into power lines for charging the power supply in the equipment to be powered. The greater the number of power lines connected in parallel, the smaller the voltage drop on the connecting lines and the less electrical loss on the connecting lines.

需要补充的是,为了适应现有电脑上的接口配置,如图1所示,第一接口11可设置成两个子接口:USB接口100和多媒体接口101。USB接口100 可以为USB2.0接口或USB3.0接口;多媒体接口101可以为HDMI接口或 DP接口。第一接口11的第一连接点110位于多媒体接口101中,第一接口 11的电源连接点111位于USB接口中。What needs to be added is that, in order to adapt to the interface configuration on the existing computer, as shown in FIG. 1 , the first interface 11 can be configured as two sub-interfaces: a USB interface 100 and a multimedia interface 101 . The USB interface 100 can be a USB2.0 interface or a USB3.0 interface; the multimedia interface 101 can be an HDMI interface or a DP interface. The first connection point 110 of the first interface 11 is located in the multimedia interface 101, and the power supply connection point 111 of the first interface 11 is located in the USB interface.

还需补充的是,可将用于控制第一可控开关从第一状态切换至第二状态的信号、用于控制第二可控开关从断开状态切换至闭合状态的信号以及控制第三可控开关从第三状态切换至第四状态的信号均设置为高电平信号,这样,一旦源设备与待供电设备断开连接后,高电平信号将不存在,第一可控开关、第二可控开关以及第三可控开关就会恢复至默认状态:即第一可控开关恢复至第一状态、第二可控开关恢复至断开状态、第三可控开关恢复至第三状态。What needs to be added is that the signal used to control the first controllable switch from the first state to the second state, the signal used to control the second controllable switch from the open state to the closed state and the signal used to control the third controllable switch The signals for switching the controllable switch from the third state to the fourth state are all set as high-level signals, so that once the source device is disconnected from the device to be powered, the high-level signal will not exist, and the first controllable switch, The second controllable switch and the third controllable switch will return to the default state: that is, the first controllable switch returns to the first state, the second controllable switch returns to the off state, and the third controllable switch returns to the third state.

As shown in FIG. 1, the connection line includes: a first interface 11, a second interface 12, a first signal line 13, a first controllable switch 14, and a first control unit 15 for controlling the first controllable switch 14; The first end of the first signal line 13 is connected to the first connection point 120 of the second interface 12, and the second end thereof is connected to the first controllable switch 14; when the first controllable switch 14 is in the first state, the second The second end of a signal line 13 is connected to the first connection point 110 of the first interface 11; when the first controllable switch 14 is in the second state, the second end of the first signal line 13 is connected to the power supply of the first interface 11 Point 111 connects.

其中,第一控制单元15可控制第一可控开关14从第一状态切换至第二状态,以及从第二状态切换至第一状态。第一接口11用于连接外部源设备,第二接口12用于连接待供电设备。第一可控开关14的默认状态为第一状态。第一接口11的第一连接点110与第二接口的第一连接点120相对应。Wherein, the first control unit 15 can control the first controllable switch 14 to switch from the first state to the second state, and from the second state to the first state. The first interface 11 is used for connecting an external source device, and the second interface 12 is used for connecting a device to be powered. The default state of the first controllable switch 14 is the first state. The first connection point 110 of the first interface 11 corresponds to the first connection point 120 of the second interface.

本实用新型实施例提供的技术方案中,连接线中第一信号线的第一端连接在第二接口的第一连接点上,第一信号线的第二端连接在第一可控开关上。与该连接线适配的待供电设备中第三信号线的第一端连接在第三接口的第一连接点上,第三信号线的第二端连接在第三可控开关上。该连接线与适配的待供电设备配合使用时,连接第二接口与第三接口,以使第二接口的第一连接点与第三接口的第一连接点连接,这样第一信号线和第三信号线相连(串联):第一可控开关为第一状态且第三可控开关为第三状态时,相连的第一信号线和第三信号线的作用即是常规的信号传输;当将第一可控开关的状态切换为第二状态且将第三可控开关的状态切换为第四状态时,相连的第一信号线和第三信号线的作用就会被切换成供电。可见,本实用新型实施例中,连接线中信号线不仅可传输信号,还可用来供电,可提高连接线中信号线的利用率。In the technical solution provided by the embodiment of the utility model, the first end of the first signal line in the connection line is connected to the first connection point of the second interface, and the second end of the first signal line is connected to the first controllable switch . The first end of the third signal line in the device to be powered adapted to the connection line is connected to the first connection point of the third interface, and the second end of the third signal line is connected to the third controllable switch. When the connection line is used in conjunction with the adapted device to be powered, the second interface is connected to the third interface, so that the first connection point of the second interface is connected to the first connection point of the third interface, so that the first signal line and The third signal line is connected (series connection): when the first controllable switch is in the first state and the third controllable switch is in the third state, the function of the connected first signal line and the third signal line is conventional signal transmission; When the state of the first controllable switch is switched to the second state and the state of the third controllable switch is switched to the fourth state, the function of the connected first signal line and the third signal line will be switched to power supply. It can be seen that in the embodiment of the present invention, the signal line in the connection line can not only transmit signals, but also be used for power supply, which can improve the utilization rate of the signal line in the connection line.
