OPS (Open Pluggable Specification, open pluggable specification) is Intel and display manufacturerThe standardized digital label interface specification formulated jointly.The inside composition of OPS computers is the mini PC of an X86-based, is usedIntel's Duo Processor is furnished with memory, hard disk, a variety of input/output interfaces and Windows operation interfaces, is equivalent to oneHost computer.
The application of existing OPS computers usually realizes that as shown in Figure 1a, first part is OPS computers by two parts, theTwo parts are OPS pinboards.OPS pinboards are OPS computers be attached with the internal wiring of all-in-one machine or television set oneBridge, can by the power supply of all-in-one machine or inside television by OPS interfaces supply OPS computers, the HDMI signals of OPS computers,AUDIO signals, USB port signal, COM port signal and switching on and shutting down push button signalling are connected to OPS by JAE-80PIN connectorsPinboard realizes signal output.The interfaces such as the USB device of all-in-one machine or television set, USB port, COM port or COM device or COM1, switching on and shutting down pass throughOPS pinboards are attached with OPS computers, in this way, only needing to plug between OPS computers and all-in-one machine or television set can be realizedDocking uses.
But as shown in Fig. 1 b and Fig. 1 c, since the OPS interfaces of OPS computers and the OPS sockets of OPS pinboards are positive anti-To can be inserted into, but it is anti-inserted when, OPS pinboard 12V/19V power ends may directly be connected with the ground in OPS computers, to leadCause the failures such as short circuit.But current OPS pinboards can not judge whether user OPS pinboards are anti-inserted.Based on this, this realityFollowing solution is proposed with novel.
As shown in Figure 2 a, OPS pinboards 100 include printed circuit board 190, and OPS interfaces are provided on printed circuit board 190110, OPS interfaces 110 include reserved pin 111, and OPS interfaces 110 with external OPS connectors 210 for connecting；
One embodiment of the utility model is provided with pull-up resistor 120 also on printed circuit board 190, and pull-up resistor 120 connectsIt is connected between the reserved pin 111 in OPS interfaces 110 and the output end of power supply 130, according to the company with external OPS connectors 210It connects position adjustment and reserves the voltage that pin 111 exports.
OPS interfaces 110 are usually 80 needle connectors, i.e. OPS interfaces 110 have 80 pins, and as shown in Figure 2 b, pin is in pairClaim setting, but, the effect of different pins is different, and OPS interfaces 110 are corresponding with the function of 210 each pin of OPS connectors, for example, the pin for being used for transmitting power supply in OPS interfaces 110 is opposite with being used for transmitting the pin of power supply in OPS connectors 210It answers, the pin for being used for being grounded in OPS interfaces 110 is corresponding with the pin for being used for being grounded in OPS connectors 210.When just connecing, both sidesThe pin of transmission power supply connects, the pin that is grounded connects, and all goes well；But when reversal connection, the pin that a side transmits power supply mayConnect with the pin of another party's ground connection, power supply will be caused to be directly grounded that short trouble occurs.
Although OPS interfaces 110 have 80 pins, being not each pin in actual design can be used, based on notThe purpose of carrying out Function Extension, is provided with some pins that will not be temporarily used more, and such pin is referred to as reserved pin.It is logicalFor often, reserved pin is in vacant state, and the corresponding reserved pin of OPS connectors 210 is also at vacant state.Hanging phaseWhen in infinite, certainly, for other pins for reserved pin, resistance value is much smaller.
Therefore, the reserved pin 111 of OPS interfaces 110 is passed through pull-up resistor 120 and power supply by one embodiment of the utility model130 are connected, when OPS interfaces 110 just connect with outside OPS connectors 210, i.e., in reserved pin 111 and OPS connectors 210Reserved pin connects, and is equivalent to reserved pin 111 and is connected with an infinite resistance, to reserved pin 111 voltage close toThe voltage (being equivalent to high level) of power supply 130；When OPS interfaces 110 and outside OPS 210 reversal connections of connector, for example, such as Fig. 2 bShown, if reserved pin 111 is No. 49 pins, when reversal connection, corresponds to No. 32 pins 112, and No. 32 pins 112 are grounding pin,Be equivalent to the ground connection of reserved pin 111, to reserved pin 111 voltage close to 0 (being equivalent to low level).That is, pull-up resistor120 can reserve the voltage that pin 111 exports, root according to the adjustment of the link position of OPS interfaces 110 and outside OPS connectors 210Reversal connection is can determine whether according to the level height of reserved pin 111.
The voltage of power supply 130 should make to export low electricity when exporting high level when reserved pin 111 is hanging, connect the resistance of small resistance valueFlat, the voltage of power supply 130 can usually select 5V DC voltages, according to OPS connectors opposite with reserved pin 111 when reversal connectionThe case where 210 link position, can adjust the voltage of power supply 130, for example, in reversal connection when corresponding pin ground connection, power supply130 voltage is more than 3.3V, other situations can be adjusted depending on concrete condition, electricity of the utility model to power supply 130Pressure is not construed as limiting.
Judge that the method for reserving the level height of pin 111 has very much, pin is reserved for example, being detected with instruments such as multimeters111 voltage, still, every time with instrument and meter come detect reserve the voltage of pin 111 can be cumbersome, if energyEnough that reminding module is arranged on OPS pinboards 100, user can judge whether reversal connection according to the prompt message of reminding module, willIt is convenient very much.Based on this, as shown in figure 3, OPS pinboards 100 further include reminding module 140；Reminding module 140 and reserved pin111 are connected, and the output voltage that pin 111 is reserved for basis sends out standby signal, such as can carry out the acousto-optic of sound-light alarmAlarm unit, such as buzzer and/or LED light etc..
Usual reminding module 140 is typically that standby signal is just sent out when receiving high level, for example, LED light is receivingIt is just lighted to when high level, buzzer just pipes when receiving high level.And as previously mentioned, in some cases, OPS interfaces110 with outside OPS connectors 210 just connect when, reserve pin 111 be high level；It is low level that pin 111 is reserved when reversal connection；JustIt is long state to connect, this will cause reminding module 140 to be chronically at working condition, can not only waste electric energy, also interfere normal use.ForThis, one embodiment of the utility model also adds detection module on OPS pinboards 100.
As shown in figure 4, detection module 150 is connected between reserved pin 111 and reminding module 140, draw for that will reserveThe output voltage of foot 111 is converted into the applicable drive signal of reminding module 140.
It is generally desirable to reminding modules 140, and prompt letter is just sent out in OPS interfaces 110 and outside OPS 210 reversal connections of connectorNumber, according to the description of front, being equivalent to hope and reserving can make reminding module 140 send out prompt letter when pin 111 is low levelNumber, one embodiment of the utility model realizes the function using detection module 150.Detection module 150 may include phase inverter or controlDevice processed.
As shown in Figure 5 a, it reserves the node that pin 111 is connect with pull-up resistor 120 with phase inverter 151 to be connected, phase inverter151 between low and high level as drive signal for exporting the output voltage of reserved pin 111 after reverse phase.When OPS interfaces 110When just being connect with external OPS connectors 210, to reserve pin 111 and export high level, high level is converted into low level by phase inverter 151,To which reminding module 140 will not send out standby signal；When OPS interfaces 110 and outside OPS 210 reversal connections of connector, pin is reserved111 output low levels, phase inverter 151 by low transition at high level, to which reminding module 140 sends out standby signal；I.e. justReminding module 140 will not send out standby signal when connecing, and reminding module 140 sends out standby signal when reversal connection.
As shown in Figure 5 b, it reserves the node that pin 111 is connect with pull-up resistor 120 with controller 152 to be connected, controller152 can be the chips such as MCU (Microcontroller Unit, micro-control unit), microcontroller, and controller 152 is used for basisThe level height of 111 output voltage of reserved pin judges the connection type of OPS interfaces 110 and outside OPS connectors 210, according toJudging result output drive signal.For example, when controller 152 detects that reserved pin 111 exports high level, judge that OPS connectsMouth 110 is just connecing with outside OPS connectors 210, can not send out drive signal at this time to reminding module 140；When controller 152 is examinedWhen measuring the output low level of reserved pin 111, judges OPS interfaces 110 and 210 reversal connection of outside OPS connectors, can send out at this timeDrive signal sends out standby signal to reminding module 140, reminding module 140 according to drive signal.Certainly, detection module 150Type can also there are many, the utility model is not construed as limiting this.

The controller, for judging OPS interfaces and the OPS according to the level height of the reserved pin output voltageThe connection type of connector, according to judging result output drive signal.
The detection module 150 can be located on the OPS pinboards 100.But, this is just needed for electronic equipment 999Detection module 150 is newly increased, although phase inverter price is relatively low, the price of controller is usually higher.And electronic equipment 999In, it is typically to have controller.
By taking electronic equipment 999 is meeting tablet as an example, meeting flat panel configurations have TV mainboards, in order to improve process performance, lead toOPS computers often can be also added in meeting tablet.Screen due to meeting tablet etc. is driven by TV mainboards, OPS electricityBrain is needed could will be on desktop projection to screen by TV mainboards, that is, OPS computers are connected by OPS pinboards with TV mainboards.
