Inventor is had found by analysis: would generally include in some connecting lines hot plug detection line (i.e. HPD signal wire),
Such as: HDMI (High Definition Multimedia Interface, high-definition multimedia interface), DP
It all include HPD signal line in (DisplayPort, display port) connecting line.Source device is used to detect by hot plug detection line
HPD signal (i.e. a high level signal), whether this HPD signal, which will start transmitting multimedia data as source device, is given equipment master
The foundation (namely source device foundation that multimedia transmission channel whether is established with equipment body) of body.HPD signal is to be powered
Equipment generates and exports a detection signal for being sent to source device.The effect of hot plug detection is when equipment body passes through connecting line
When being connected or disconnect with source device, source device can detect this event by the HPD pin of interface, and make sound
It answers.As it can be seen that source device detects HPD signal by hot plug detection line, then it can illustrate that equipment to be powered has connected, it can be with confession
Electric equipment sets up the transmission that multi-media signal transmission channel carries out multi-medium data.
In addition, there are also the hot plugs being used cooperatively with hot plug detection line to detect auxiliary line in some connecting lines, such as:
HDMI_5V signal wire in HDMI connecting line.Equipment body detects auxiliary line by hot plug to detect an auxiliary signal (i.e. one
High level signal), which generates from source device and exports a detection signal for being sent to equipment body, and equipment body is logical
It crosses hot plug detection auxiliary line and detects auxiliary signal, can judge that source device has accessed, and generate HPD signal and insert by heat
It pulls out detection line output to send to source device, to carry out the detection of HPD signal by source device.
During multi-medium data transmission, hot plug detection line and hot plug detection auxiliary line in connecting line are simultaneously
It is not used in transmitting multimedia data, therefore can be after the completion of multimedia transmission Path Setup, by the hot plug detection line in connecting line
And/or hot plug detection auxiliary line is used to power.
Therefore, when it is implemented, being used for transmission the signal of multi-medium data in order to not influence those in existing connecting line
The work of line, above-mentioned first signal wire 13 can be specially hot plug detection line or hot plug detection auxiliary line.
In the existing transport protocol based on connecting line, after multimedia transmission Path Setup gets up, source device will also be after
Continuous detection HPD signal, to ensure that equipment body is constantly in connection；Once source device does not detect HPD signal, then can stop
The only transmission of multi-medium data.
When the first signal wire and third signal wire are hot plug detection line, once the first signal wire is switched into power supply
Line, the first tie point of first interface are at suspended state, i.e. source device just can not by the first tie point of first interface
Detect HPD signal, then, source device can stop the transmission of multi-medium data, this is necessarily affected according to existing transport protocol
The normal transmission of multi-medium data.
In order to adapt to existing transport protocol, connecting line 1 further include: first resistor 20 and controlled by first control unit 15
The second controllable switch 16；First resistor 20 and the second controllable switch 16 are connected in series in the first tie point of first interface 11
Between 110 and the power connection points 111 of first interface 11.
In use, as depicted in figs. 1 and 2, once after multimedia transmission Path Setup, the control of first control unit 15 the
One controllable switch 14 switches to the second state from first state (" 1 " that corresponds to SW1 in figure) and (corresponds in Fig. 1 in SW1
" 2 ") while, control the second controllable switch 16 from off-state (i.e. correspond to figure in SW3 " 2 ") switch to closed state
(" 1 " that corresponds to SW3 in figure).In this way, the first tie point 110 of first interface 11 just connects with the power supply of first interface 11
Contact 111 connects.The power connection points 111 of first interface 11 need to provide supply current to equipment body, therefore first connects
The power connection points 111 of mouth 11 can be constantly in high level state.So, source device passes through the first tie point of first interface 11
110 are able to detect that high level signal (i.e. HPD signal), and source device will continue to transmitting multimedia data.
In addition, in the existing transport protocol based on connecting line, the signal processing unit in equipment body 2 be also required to after
Continuous detection auxiliary signal, to ensure that source device is constantly in connection status, once signal processing unit can't detect auxiliary signal,
Then signal processing unit will stop exporting HPD signal to source device, in this way, source device can also stop the biography of multi-medium data
Defeated, this has necessarily affected the normal transmission of multi-medium data.
When the first signal wire and third signal wire are hot plug detection auxiliary line, once third signal wire is switched to
Power supply line, the first tie point of signal processing unit are at suspended state, i.e. signal processing unit passes through its first tie point
It can not just detect auxiliary signal.Signal processing unit can not detect auxiliary signal, will stop exporting HPD letter to source device
Number.So, source device can stop the transmission of multi-medium data, this has necessarily affected multimedia number according to existing transport protocol
According to normal transmission.
In order to avoid such case appearance, above equipment main body may also include that the 4th controllable switch 29 and second resistance
30；4th controllable switch 29 and second resistance 30 are connected in series in first tie point (such as Fig. 2 of the signal processing unit
Shown in HDMI ▁ 5V) and the power connection points 211 of the power supply 21 between；4th controllable switch 29 and second control
Unit 26 processed connects.
In use, as depicted in figs. 1 and 2, once after multimedia transmission Path Setup, the second control unit 26 control the
Three controllable switches 25 (such as: the SW20 in Fig. 2) the 4th state is switched to from the third state (" 1 " that corresponds to SW20 in figure)
While (corresponding to " 2 " in Fig. 2 in SW20), the 4th controllable switch 29 of control (corresponds in figure from off-state
" 1 " of SW30) switch to closed state (" 2 " that correspond to SW30 in figure).In this way, the first of signal processing unit 23 connects
Contact 230 (such as: Fig. 2 shows display IC HDMI ▁ 5V) just connect with the power connection points 211 of power supply 21.Electricity
The power connection points 211 in source 21 are used to receive the supply current of source device offer, therefore the power connection points 211 of power supply 21 understand one
Directly it is in high level state.So, signal processing unit can be able to detect that high level signal (i.e. by its first tie point
Auxiliary signal), so, that is, it can ensure that source device can continue transmitting multimedia data.
Further, in above-mentioned connecting line 1 further include: the power connection points 111 and second for being connected to first interface 11 connect
The first power supply line 19 between the power connection points 121 of mouth 12；In above equipment main body 2 further include: be connected to third interface 22
Power connection points 221 and power supply 21 power connection points 211 between second source line 28；When second interface 12 and third
When interface 22 connects, the connection of power connection points 221 of the power connection points 121 of second interface 12 and third interface 22, it can be achieved that
The connection (series connection) of first power supply line 19 and second source line 28.
When external source device is connect by connecting line 1 with equipment body 2, the first end and third of the first signal wire 13 are believed
The first end connection of number line 24；If the second end of the first signal wire 13 is connected in the power connection points 111 of first interface 11, and
The second end of third signal wire 13 is connected in the power connection points 211 of power supply 21, then concatenated first signal wire 13 and third
I.e. with concatenated first power supply line 19 and second source line 28 in being arranged in parallel, the resistance on connecting line becomes smaller signal 13, can drop
Pressure drop and electrical loss on low connecting line.
In recent years, it with the continuous development of virtual reality and augmented reality, wears display equipment and is widely used.Mesh
Before, it largely wears display equipment and needs to connect by connecting line with computer, powered by computer, and provided by computer for playing
Multi-medium data.Wearing display equipment need to be powered (such as: USB3.0,5V/900mA), and mesh by the USB interface of computer
Before wear the power consumption of display equipment and have been approached the power supply limit of computer USB interface.In order to guarantee good user experience, for connecting
4m or more need to be arranged in connecting line (Cable line) length for wearing display equipment again by connecing computer.And so, on connecting line
Electrical loss will be very big, easily lead to and wear display equipment and be difficult to power consumption needed for reaching its operation, display equipment is worn in influence
Normal work.Using connecting line provided by the embodiment of the utility model and display equipment is worn, can effectively reduce on connecting line
Pressure drop and electrical loss.
It in the specific implementation, can be by the hot plug detection line in concatenated connecting line after multimedia transmission Path Setup
With the hot plug detection line in equipment to be powered and the detection auxiliary line of the hot plug in concatenated connecting line and equipment to be powered
In hot plug detection auxiliary line be all multiplexed into power supply line, charged with treating power supply in power supply unit.A greater number of electricity
Source line is in parallel, and for the pressure drop on connecting line with regard to smaller, the electrical loss on connecting line is fewer.
You need to add is that in order to adapt to the configuration of the interface on existing computer, as shown in Figure 1, first interface 11 is settable
At two sub-interfaces: usb 1 00 and multimedia interface 101.Usb 1 00 can connect for USB2.0 interface or USB3.0
Mouthful；Multimedia interface 101 can be HDMI interface or DP interface.First tie point 110 of first interface 11 connects positioned at multimedia
In mouth 101, the power connection points 111 of first interface 11 are located in USB interface.
Also need supplement, can by be used to control the first controllable switch from first state switch to the second state signal,
For controlling signal and control third controllable switch that the second controllable switch switches to closed state from off-state from third
The signal that state switches to the 4th state is disposed as high level signal, once in this way, source device and equipment to be powered disconnect and connecting
After connecing, high level signal will be not present, and the first controllable switch, the second controllable switch and third controllable switch will restore to silent
