The OPS interface of below take describes computer and television integrated machine according to an embodiment of the invention in detail as example.
Fig. 2 and Fig. 3 show take the application schematic diagram of the computer and television integrated machine that the OPS interface is example according to an embodiment of the invention.
Because current main frame is more and more less, therefore INTEL Corp. has formulated the interface specification of standard set minihose: OPS(Open Pluggable Specification), it is the set of a common interfaces, such as integrated USB connect, the function of the interface such as HDMI/DVI interface.Television set/monitor has increased this interface, the computer module that meets this standard interface can directly be installed easily.But this interface has only provided interface definition, see below, do not provide concrete control method and control flow.Need to formulate voluntarily corresponding control method goes the computer module on docking port to be controlled.
As shown in Figure 2, OPS module 202 in Fig. 2 and interface board 204 can be corresponding to the interface modules in Fig. 1, certainly, although interface board 204 is provided in Fig. 2, should be understood that in application system, also can not need interface board 204, directly OPS module 202 is connected to TV motherboard 208, as shown in Figure 3.TV motherboard 208 in Fig. 2 can be corresponding to the control device of the tv 102 in Fig. 1, certainly TV motherboard 208 is except comprising control device of the tv, can also comprise other modules, hereinafter the function to the control device of the tv relevant with the present invention only is described, the function of other functional modules does not repeat them here.
Continuation referring to figs. 2 and 3, OPS module 202 is with female seat, the model of this female seat is 80PINJAETX25 for example, and corresponding male seat is arranged on interface board 204.OPS interface 202 contains one group of power supply, is powered to OPS module 202, can be independent power module (for example power panel 206), also can share a power module (for example main power board shown in Fig. 3 210) with mainboard; The TMDS signal of one group of HDMI/DVI, be used for transmitting the vision signal that OPS module 202 is exported; One group of DP (Displayport) signal, can be used for directly lighting the liquid crystal display screen with the DP mouth, also can use to the television set with the DP interface/monitor; 3 groups of USB interface, according to being used for connecting touch-screen or miscellaneous equipment for example USB memory device, camera, RFID equipment etc.; One group of control signal (PS_ON: starting-up signal; PB_DET:OPS interface detection signal; PWR_STATUS:OPS operating state detection signal) can be convenient to use the work that mechanical key or sophisticated software control flow remove to control OPS; Also have in addition one group of AUDIO signal, can transmit one group of audio signal to television set/monitor; One group of UART signal, can allow between OPS module and television set/monitor, communicate, control etc.; A fan control signal, can add switching value or PWM amount in the situation that need extra heat dissipation to be controlled fan easily.
The above has simply described some definition of OPS interface, only for the function relevant with the present invention, is set forth hereinafter.
With reference to figure 3 and Fig. 4, interface module described in Fig. 1 104 is corresponding to the OPS interface in Fig. 3 and OPS module 202, and in Fig. 4, the OPS module shown in Fig. 3 is integrated in computer module 106.
As shown in Figure 4, the OPS interface comprises the first state feedback line (PB_DET), control line (PS_ON) and the second state feedback line (PWR_STATUS), and these definition of controlling feedback line see table.
As shown in Figure 3, add R1, R2, tri-pull-up resistors of R3 to respectively on circuit the signal on two state feedback lines and control line.
On the GPIO of PS_ON on control device of the tv (TV/Monitor MCU) 102, it is an output signal.Export at ordinary times high level, the power knob that is equivalent to computer is in down state not.
When needs provide starting-up signal, for example, if set low level and continue certain setting-up time section (400ms), the power knob that is equivalent to computer module is pressed and is decontroled.Need on computers the function that defines power knob to be: " start/shutdown " simultaneously.After PS_ON triggers, if computer is in off-mode before triggering, computer can be started shooting; If computer is in off-mode before triggering, computer can shut down.
PWR_STATU is the working state signal of computer.On GPIO on TV/Monitor MCU, be an input signal, be low level when the booting computer state, can lose the control of computer module 106 after shutdown, because there is pull-up resistor to exist, can become high level.
PB_DET is an earth connection in computer end, on the GPIO on TV/Monitor MCU, is an input signal.When computer module does not insert, owing to there being the pull-up resistor existence can show as high level, when inserting the OPS interface, now level can be dragged down, and shows low level.
Therefore, that is to say, described the first state feedback line is for transmitting the status signal whether computer module is installed, and control line triggers for transmitting the signal that computer module carries out switching on and shutting down, and described the second state feedback line is for the signal of the on-off state that transmits computer module.
After the effect of having introduced two state feedback lines and a control line, below just explain that control device of the tv 102 and described computer module 106 are how based on these two state feedback lines and control line, to complete start, standby, passage switching and prevent the function such as hot plug.
Then with reference to figure 3 and Fig. 4, control device of the tv 102(is the TV SKD 208 in Fig. 3) also be connected to power panel (for example special OPS power panel 206), as shown in Figure 3, OPS power panel 206 is connected to control device of the tv 102 and computer module 106, to receive from control device of the tv 102(be TV SKD 208) start signal (19V_ON/OFF) time, open the power supply circuits into computer module 106 power supplies.
This control device of the tv 102 is when television startup, judge according to the status signal of the first state feedback line (PB_DET) transmission whether computer module 106 is installed, determining while computer module 106 being installed, send start signal to OPS power panel 206, to open the power supply circuits of computer module 106, and judge whether the current demand signal source channels is the specification signal source channels corresponding with interface module (being the OPS interface), if the current demand signal source channels is this specification signal source channels, by control line (PS_ON), send the control signal that triggers computer module 106 starts, otherwise, do not send the signal that triggers computer module 106 starts.
Control device of the tv 102 is also for after triggering computer module 106 starts, the on-off state of the described computer module 106 of input transmitted according to the second state feedback line (PWR_STATUS) after the first predetermined amount of time, if described computer module 106, in off-mode, is pointed out manually opened described computer module.
Therefore, when television startup, at first judge whether to be equipped with computer module, when computer module being installed, continue to judge whether the current demand signal source channels is the OPS passage, if, what before illustrating, the user used is exactly the OPS passage, then makes the computer module start, also needs to determine according to the on-off state of computer module whether computer module starts shooting, if also do not start shooting point out the user, needing the user manually to start shooting.Therefore, when television startup, can control computer and also start shooting, avoid the independent start of telecomputer, without user's manual operation.
More than described the start of computer and television integrated machine and controlled processing procedure, the Opportunity awaiting control for linear processing procedure of computer and television integrated machine has been described below.
Described control device of the tv is also for when described control device of the tv receives standby signal, the on-off state of the input computer module 106 transmitted according to described the second state feedback line, at computer module 106 during in off-mode, send shutdown signal to power panel (example is the OPS power panel as shown in Figure 3), close the power supply circuits of computer module 106, TV enters holding state, and, by described control line, trigger and close computer module 106 during in open state at computer module 106.In order to ensure computer module in off-mode, can detect every the second predetermined amount of time the signal of three control line transmission, to judge that whether computer module 106 is in off-mode, if computer module 106 is still in open state, continue to send shutdown signal to power panel, to close the power supply circuits of computer module 106, TV enters holding state.
Under some application scenarios, can be set the time of closing display, when closing display, the vision signal no-output, the detection computer is open state, now just closes backlight.Use mouse and keyboard or touch-screen all can wake computer, outputting video signal again up.Television set/monitor detect after vision signal reopen backlight.
At computer in sleep state, perhaps in resting state or user, initiatively close computer, the equal no-output of vision signal, the detection computer module is off-mode, now show that the user does not use computer module for a long time, if provide under this scene, in the 3rd scheduled time of prompting, the user is without wake operation or initiatively start operation, and television set/monitor can enter holding state, can further reduce like this consumption of electric energy.
For computer and television integrated machine, also relate to the switching of signal source passage under some scene, therefore, control device of the tv 102 is when being used the specification signal source channels (use OPS passage) relevant to described computer module, if switch to other passages, keep described computer module in open state (current use OPS passage, although switch to other passages, can think that the user switches to other passages temporarily, also can switch back afterwards the OPS passage, therefore make computer module 106 still in open state, conveniently from other passages, switch back the OPS passage, avoided repeatedly computer module being carried out the operation of switching on and shutting down, the stability of raising system), and when from described other passages, switching to described specification signal source channels, the on-off state of the described computer module of input transmitted according to described the second state feedback line, if described computer module is in off-mode, by described control line, trigger described computer module start.
Insert computer module at TV during in open state and can cause larger surge impact to power supply, or the HDMI interface of television set/monitor and computer is caused to static damage, also can the hard disk of computer be caused than macrolesion.For fear of this problem, also provide the function that prevents hot plug according to computer and television integrated machine of the present invention, the following description:
Control device of the tv 102 is also for after television startup, detect the signal of the first state feedback line transmission every the 4th predetermined amount of time, to determine whether to be equipped with computer module 106, if determine computer module 106 be not installed, according to the second state feedback line, detect the on-off state of computer module 106, if and determine that computer 106 be off-mode, to power panel, send shutdown signal, with the power supply circuits of closing computer module 106 closed condition that keeps power supply circuits 106 until TV shut down.After so just can being limited to television startup, until the process of shutdown does not allow to insert computer module 106, even insert computer module 106, power supply circuits can, for computer module 106 power supplies, not prevent surge impact and static damage yet.
Fig. 5 shows the flow chart of computer and television integrated machine control method according to an embodiment of the invention.
As shown in Figure 5, the computer and television integrated machine control method can comprise the following steps according to an embodiment of the invention:
In technique scheme, preferably, described control device of the tv detects the state of computer module, and the step of controlling the operation of described computer module according to the state of described computer module specifically comprises: when described television startup, judge whether described computer module is installed; When described computer module is installed, opens the power supply circuits of described computer module and judge whether the current demand signal source channels of TV is to specify the signal source passage; If the current demand signal source channels is described specification signal source channels, trigger described computer module start, otherwise, do not trigger described computer module start.
In technique scheme, preferably, can also comprise: after triggering described computer module start, detect the on-off state of described computer module after the first predetermined amount of time, if described computer module in off-mode, is pointed out manually opened described computer module.
In technique scheme, preferred, can also comprise: when described control device of the tv receives standby signal, described control device of the tv detects the on-off state of described computer module; During in off-mode, close the power supply circuits of described computer module at described computer module, described TV enters holding state; At described computer module during in open state, described computer module is closed in triggering, and whether detects described computer module in off-mode every the second predetermined amount of time, if in open state, close the power supply circuits of described computer module, described TV enters holding state.
In above-mentioned arbitrary technical scheme, preferably, can also comprise: the state that detects described computer module at described control device of the tv is off-mode, and while exporting without the video signal, if the prompting after the 3rd predetermined amount of time to TV without any operation, described TV enters holding state.
In above-mentioned arbitrary technical scheme, preferred, can also comprise: when described computer and television integrated machine is used the specification signal source channels relevant to described computer module, if switch to other passages, keep described computer module in open state; When from described other passages, switching to described specification signal source channels, described control device of the tv detects the on-off state of described computer module, if described computer module in off-mode, triggers described computer module start.
In above-mentioned arbitrary technical scheme, preferably, can also comprise: after described television startup, every the 4th predetermined amount of time, detect whether described computer module has been installed, if determine described computer module be not installed, detect the on-off state of described computer module; If determine, described computer module is off-mode, closes the power supply circuits of described computer module and keeps the closed condition of described power supply circuits until the shutdown of described TV.
Increase the OPS passage in the signal source of TV/monitor, the OPS passage can show the vision signal of OPS module, and now television set/monitor is as the computer module display.In order to increase man-machine interaction, simultaneously, need to add the switching on and shutting down option of computer in television set/monitor user menu, according to the detection to the PWR_STATUS state, when PWR_STATUS=L(computer state for opening) time, button can only be chosen " shutdown "; When PWR_STATUS=H(computer state is pass) can only choose the shutdown button, operation when as the user, initiatively removing the switch computer.Also can on user remote controller or on television set/monitor the machine button, the switching on and shutting down button be set in addition, reply user's active switching on and shutting down operation, also can play the effect of a key switch machine.When the user presses start or shutdown button, mean that the user will use computer module, signal source is switched to the OPS passage, shows the switching on and shutting down process of computer.
For prevent that the detection that single line detects each IO of this programme of makeing mistakes from needing to add anti-shake mechanism, after once sampling IO state every certain setting-up time section for example 200ms can again detect once, just the state consistency of twice thinks that port is definite state.
Control for the OPS computer module mainly contains the following aspects:
1. start determines whether power to computer according to the installment state of computer module;
2. whether open computer according to signal source passage, current computer work Determines;
3. need to close computer before standby;
4. the judgement of computer work state and countermeasure.
Below describe the specific implementation process of top each side in detail.

Step 804, now first detect the state of PWR_STATUS, if PWR_STATUS=H, computer is off-mode, enters step 812, otherwise enters step 806.
Step 812, now should close the power supply circuits of OPS module and normally enter holding state.
Step 806, if PWR_STATUS=L shows that computer is in open state, now trigger the PS_ON signal and remove to close computer.
Step 808, shutdown is a longer process.Now should for example, remove the state of run-down PWR_STATUS every predetermined amount of time (500ms), judge whether computer shuts down.If become H show to shut down complete, and then closing standby after 19V power supply; If the state of PWR_STATUS is L, enter step 810.
Step 810, if reach 60S detection time, PWR_STATUS is still L, showing can't normal shutdown, enters step 812, enters standby mode after directly closing computer 19V power supply, if do not reach 60S, gets back to step 808.
Except the control processing procedure of the start of foregoing description, standby and passage switching, also relate to the control processing procedure under special screne, for example in the user uses the process of OPS module, unavoidably can be set the time of closing display, or the time of computer sleep is set.The state of closing display is PWR_STATUS=L, the output of HDMI no signal.Now television set/monitor respective operations should be backlight for closing, and constantly scan the vision signal of OPS passage.Use mouse the user, keyboard or touch-screen are opened backlight after waking computer up and loading vision signal.
When computer enters sleep state, PWR_STATUS=H, the output of HDMI no signal.When television set/monitor detects OPS passage HDMI no signal, and PWR_STATUS=H, two kinds of possibilities are now arranged: computer enters sleep pattern, park mode or user initiatively close computer, these three kinds of situations all show that the user does not re-use the OPS module or do not use for a long time module, now the screen prompt user does not carry out any operation television set/monitor and will enter standby mode after 15 minutes, to save power supply.
In order further to protect computer and television integrated machine; the present invention also provides the method that prevents hot plug: owing at open state, inserting computer module, can cause larger surge impact to power supply; perhaps the HDMI interface of television set/monitor and computer caused to static damage, also can the hard disk of computer be caused than macrolesion.Therefore control the state that only when start, detects PB_DET, the power supply whether Determines during according to start opens 19V.Can remove every a period of time the state of run-down PB_DET after the start simultaneously, if state changes, remove again to detect the state of PWR_STATUS, if PWR_STATUS=H shows that computer module is not on interface.Now 19V can be closed until start next time removes to detect the state of PB_DET again.So just effectively avoid user's injury that the warm swap computer module brings repeatedly.
