Embodiment
Below in conjunction with accompanying drawing structural principle of the present invention and principle of work are done concrete description:
The present invention proposes a kind of host apparatus and inserting state detection method thereof, utilizes the inserting state of internal hardware wireline inspection host apparatus to reach the mechanism of fool proof, and can reach the symmetric purpose of outward appearance.
Please refer to Fig. 1, it is the synoptic diagram of the host apparatus of preferred embodiment of the present invention.Host apparatus 100 comprises an a connector 110 and a control circuit 120.Connector 110 has many pins (pin), and these a little pins comprise that one detects a pin and a control pin.Control circuit 120 is electrically connected to connector 110, and the voltage of setting control pin is a ground voltage.Whether the present invention comes down in order to the inserting state that detects a host apparatus 100 and an outside appurtenances 10 correct, and wherein outside appurtenances 10 also has a connector 20, and this connector 20 has the pin identical with connector 110.
Next lift connector 110 and 20 now and do explanation for example, wherein connector 110 and 20 has 11 pins respectively, so is not limited to this.Please refer to Fig. 2 and Fig. 3, Fig. 2 is the connector pairing figure of forward when pegging graft for host apparatus and outside appurtenances, and the connector when Fig. 3 be a host apparatus with outside appurtenances for reverse grafting matches schemes.In Fig. 2 and Fig. 3, the FM pin is in order to receive the frequency-modulated antenna input signal, the GND pin is in order to receive ground voltage, the ID pin is in order to receive identification signal, D+ pin and D-pin are in order to receive differential data, L pin and R pin are in order to receive left and right sound track signals, the KD pin is in order to detect keyboard (keyboard) signal (about 1.5 volts) or joystick (cradle) signal (about 0.5 volt), the SD pin is in order to detect loudspeaker (speaker) signal (about 1.5 volts), the CTRL pin is the amplifier in order to the activation inside loudspeakers, and POWER is power supply signal.
In Fig. 2 and Fig. 3, be to serve as to detect pin 112, and serve as control pin 114 with the CTRL pin with the SD pin.At this moment, the voltage of control pin 114 is that Be Controlled circuit 120 is set at ground voltage GND.When outside appurtenances 10 was connected with host apparatus 100 via connector 20 and 110, control circuit 120 can judge whether detect pin 112 receives a voltage decided at the higher level but not officially announced.Wherein, detect pin SD corresponding to detecting pin 112 for loudspeaker, voltage decided at the higher level but not officially announced is 1.5 volts.
In Fig. 2,, form a reference potential so both GND pins are corresponding mutually because connector 110 is pegged graft for forward with connector 20.Thus, the detection pin 112 of connector 110 can remove to respond to the SD pin of connector 20, and can receive 1.5 volts of voltages decided at the higher level but not officially announced.Receive voltage decided at the higher level but not officially announced when detecting pin 112, then control circuit 120 can judge that host apparatus 100 and outside appurtenances 10 are the forward grafting.Therefore, control circuit 120 voltage that will control pin 114 switches to control voltage CTRL by ground voltage GND.Thus, host apparatus 100 can be linked up with outside appurtenances 10.
In Fig. 3, because connector 110 is oppositely to peg graft with connector 20, the control pin 114 of connector 110 can correspond to the GND pin of connector 20 at this moment.Therefore because the voltage Be Controlled circuit 120 of control pin 114 is set in ground voltage GND, controlling pin 114 can be corresponding mutually with the GND pin of connector 20 and form a reference potential.Thus, the detection pin 112 of connector 110 can remove to respond to the ID pin of connector 20.Because detect the identification signal that pin 112 can't receive the ID pin,, that is can't receive 1.5 volts of voltages decided at the higher level but not officially announced so its voltage is 0 volt.
Can't receive voltage decided at the higher level but not officially announced when detecting pin 112, then control circuit 120 can judge that host apparatus 100 and outside appurtenances 10 are oppositely to peg graft.Therefore, the voltage that control circuit 120 is kept control pin 114 is ground voltage and sends a wrong grafting signal, serves as oppositely to peg graft to notify user's host apparatus 100 and outside appurtenances 10.The connector 110 in the present embodiment and 20 because being the inserting state that utilizes control circuit 120 to detect host apparatus 110, present embodiment reaches the mechanism of fool proof, so can keep the outward appearance symmetry.And owing to can keep the outward appearance symmetry, connector 110 and 20 has more pins that more abundant space can be provided with difference in functionality.
Please refer to Fig. 4, it is the process flow diagram of the detection method of the host apparatus inserting state of preferred embodiment of the present invention.Host apparatus comprises an a connector and a control circuit, and connector has one and detects a pin and a control pin, and control circuit is electrically connected to connector.In step S400, the voltage that control circuit is set the control pin is a ground voltage.In step S410, make host apparatus connect an outside appurtenances via connector.In step S420, judge whether detect pin receives a voltage decided at the higher level but not officially announced.Receive voltage decided at the higher level but not officially announced if detect pin, in step S430, the voltage of control circuit switching controls pin is a control voltage.Do not receive voltage decided at the higher level but not officially announced if detect pin, in step S440, the voltage that control circuit is kept the control pin is ground voltage and sends a wrong grafting signal.
The operation principles of the detection method of above-mentioned host apparatus inserting state has been specified in the related content of the host apparatus 100 of Fig. 1～Fig. 3, so no longer repeat in this.
Disclosed host apparatus of the above embodiment of the present invention and inserting state detection method thereof have multiple advantages, below only enumerate the part advantage and are described as follows:
Host apparatus of the present invention and inserting state detection method thereof, be same pin different voltage being shared connector by the mode of switching, and the inserting state that utilizes internal hardware wireline inspection host apparatus reaches the mechanism of fool proof, not only can reach the symmetric purpose of outward appearance, also can improve the quantity of available pins.
Certainly; the present invention also can have other various embodiments; under the situation that does not deviate from spirit of the present invention and essence thereof; those of ordinary skill in the art work as can make various corresponding changes and distortion according to the present invention, but these corresponding changes and distortion all should belong to the protection domain of the appended claim of the present invention.
