Referring to Fig. 1, the present invention provides a kind of control method, is applied to electronics, described electronics comprises N number of input and output I/O interface, and described N number of I/O interface is connected with for electric line and data circuit, N is positive integer, and described method can comprise the following steps:
Step 11: when the I/O interface detected in described N number of I/O interface is connected with first coupling device with the first identification marking information, obtain the voltage fluctuation parameter that described first coupling device is corresponding.
In the embodiment of the present invention, I/O interface can be an electronic circuit (occurring with IC chip or interface board form), having some special registers and corresponding control logic circuit to form in it, it is medium and the bridge of CPU and I/O exchanged between equipment information.
Usually, the function of I/O interface can realize CPU by system bus together with the contact of I/O circuit and peripherals, according to the complexity of circuit and equipment, the hardware of I/O interface mainly can be divided into I/O interface chip and I/O interface control card, wherein, I/O interface chip is mostly unicircuit, different orders and parameter is inputted by CPU, and controlling relevant I/O circuit and simple peripheral hardware is done to operate accordingly, common interface chip is such as Timer/Counter, interruptable controller, DMA controller, parallel interface etc.; And I/O interface control card refers to that some unicircuit become parts by certain logical groups, or directly and CPU coexist on mainboard, or a plug-in unit is inserted on system bus slot. In the embodiment of the present invention, described N number of I/O interface can mainly refer to and can the USB interface (UniversalSerialBus, the total line interface of general serial) of support adapter in electronics.
In the embodiment of the present invention, described N number of I/O interface connects by connecting joint and peripheral hardware, such as mouse, adapter etc., and has plug and play and hot plug function. Concrete, the connection relation of described N number of I/O interface and described feed circuit and described data circuit is as shown in Figure 2. Wherein, for the coupling device of USB or adapter is connected with the circuit of electronic equipment internal by described N number of I/O interface.
Need illustrate time, described electronics can be provided with and the latch that described N number of I/O interface is connected, described latch can described N number of I/O interface circuit be connected, in concrete system line, please still see Fig. 2, described latch can be in the square frame being in and representing I/O interface, then when detection determines that having described M coupling device is connected with M I/O interface, latch is triggered, and according to the time order and function order connected, undertaken latching record by the pin mark of the device corresponding with described M I/O interface in real time, to distinguish the time order and function of each coupling device insertion, and then determine the first coupling device accessing described M I/O interface at first.
Optionally, in the embodiment of the present invention, when being in connection state when between described N number of I/O interface and described confession electric line, the level that each the I/O interface in described N number of I/O interface is corresponding is high level. And the protocol signal of USB adapter function is realized by ID pin, and adapter working order when ID pin is in high level, can be opened, so that the adapter of access is responded by electronics.
Actual realize in process, when described first coupling device is connected with a described I/O interface, the connecting joint of described first coupling device can as male, the side that namely joint protrudes, a described I/O interface can as female, and namely interface falls in the side preparing to be connect. Therefore, described first identification marking can refer to the ID pin mark of described first coupling device, and a described I/O interface has the function identifying described ID pin mark. Shown in Figure 3, a represents the mark of the ID pin in described first coupling device, i.e. male; B represents in described N number of I/O interface for identifying and the interface mated mutually with described first identification marking, i.e. female. Wherein, IDa is used as system identification, and IDb is used as adapter functions identification, and IDa ' and IDb ' mates with IDa and IDb respectively.
Concrete, described first identification marking can be the described first distinctive device identification of coupling device, when the described first coupling device described I/O interface of insertion, by the detecting circuit being connected with a described I/O interface can identify described first coupling device whether can with the power supply connection in described electronics. Such as, if described first coupling device is adapter, then described first identification marking is the mark corresponding with adapter, and when adapter inserts a described I/O interface, described electronics can detect and obtain the voltage fluctuation parameter that described first coupling device is corresponding.
Concrete, it is determined that the process of described voltage fluctuation parameter is:
1) in the first moment, detection determines to there is M the coupling device being connected by M I/O interface in described N number of I/O interface with described electronics, obtaining M the pin identification information that described M coupling device is corresponding, M is more than or equal to the integer that 1 is less than or equal to N;
2) whether described M pin is identified in identifying containing described first identification marking;
3) if having, the coupling device corresponding with described first identification marking is defined as described first coupling device;
4) the 2nd moment differing preset duration with described first moment after described first moment, detection obtains the voltage fluctuation parameter information corresponding with described first coupling device.
Wherein, described N number of I/O interface can be carried out real-time detection by described electronics, when determining the device with connection, the moment that can be connected by this device is as described first moment, so that it is determined that go out described M the pin mark that described M the coupling device connected is corresponding, then by the identification of described M pin mark can be judged whether to there is described first identification marking, if existing, then can determine to be defined as the coupling device corresponding with it described first coupling device. Therefore described first coupling device in described M coupling device with described first identification marking can be determined by real-time detection comparatively fast, to carry out corresponding control circui by the interface corresponding to described first coupling device.
Optionally, described electronics can be provided with and the latch that described N number of I/O interface is connected, described latch can be connected with the I/O interface circuit in circuit shown in Fig. 2, namely the position being in described latch can be in the square frame being in and representing I/O interface, then when detection determines that having described M coupling device is connected with M I/O interface, latch is triggered, and according to the time order and function order connected, undertaken latching record by the pin mark of the device corresponding with described M I/O interface in real time, to distinguish the time order and function of each coupling device insertion, and then determine the first coupling device accessing described M I/O interface at first.
Further, after determining described first coupling device, the I/O interface corresponding with described first coupling device can be defined as a described I/O interface, and the 2nd moment of preset duration is being differed with described first moment, detect the voltage parameter of described first coupling device, and this voltage parameter is defined as corresponding voltage fluctuation parameter. When described voltage fluctuation parameter refers to a described first coupling device insertion described I/O interface, owing to being connected the pin frequency hopping causing described first coupling device with the inside system of electronics, thus cause the voltage fluctuation of described first coupling device. Therefore, described preset duration can be after insertion coupling device, and the time of pin frequency hopping occurs. Such as, described preset duration can be 100ms. Therefore, described electronics can using the voltage parameter of described first linking device that detects in described first moment as voltage fluctuation. Such as, if the default voltage of adapter pin is 5V, after insertion I/O interface generation frequency hopping, the voltage of its correspondence is 3.0V, then the voltage fluctuation parameter recorded in described 2nd moment is just 3.0V.
Step 12: judge whether described voltage fluctuation parameter is in preset range, obtains a judged result.
In the embodiment of the present invention, described preset range can be determined according to the pin operating voltage of described first coupling device. Usually, the pin voltage of adapter maintains 3.3V, and under the impact of frequency hopping, the voltage fluctuation of upper and lower 10% can be there is, namely voltage has the fluctuation of about 0.3V up and down, and therefore, described preset range can be set to 3.0V-3.6V, then whether can be in this preset range in the voltage fluctuation parameter that described first coupling device of described 2nd moment detection is corresponding, so that it is determined that whether described first coupling device is adapter.
Step 13: the break-make connection state between N-1 the I/O interface controlled in described N number of I/O interface except a described I/O interface based on described judged result and described confession electric line.
In the embodiment of the present invention, the break-make connection state between described N-1 I/O interface and described confession electric line specifically comprises disconnection state and connection state. Wherein, when described break-make connection state is off state, in described N number of I/O interface, only an I/O interface keeps the connection between described confession electric line; And when described break-make connection state is connection state, each the I/O interface in described N number of I/O interface all communicates for electric line with described, therefore described N number of I/O interface all can detect whether coupling device has described first identification marking.
Optionally, in the embodiment of the present invention, if judging, described voltage fluctuation parameter is in described preset range, then control described break-make connection state and it is off state, and described first coupling device is defined as the unique and described device being connected for electric line, the adapter functions of described first coupling device namely can be realized by a described I/O interface. Now, in described N number of I/O interface, described N-1 the I/O interface except a described I/O interface disconnects and the described connection for electric line so that described N-1 I/O interface only keeps USB to connect function.
In actual, due to before access coupling device, the level that described N number of I/O interface is corresponding is high level, and the protocol signal of USB adapter function is realized by ID pin, ID disciplines high-voltage can open adapter working order, therefore, when described break-make connection state is in disconnection state, only there is the corresponding high level of a described I/O interface, there is adapter functions.
Concrete, when realizing the adapter function of supplying power forbidding described N-1 I/O interface, can be, by controlling described electronics, level corresponding for described N-1 I/O interface is switched to lower level by described high level, owing to adapter working order just can be opened when ID supervisor is in high level, therefore when by the level of described N-1 I/O interface by high level draw low for lower level time, adapter will no longer be responded by described N-1 I/O interface, and USB function is only provided, such as connect USB flash disk, mouse, keyboard etc.
Wherein, when the level drawing low described N-1 I/O interface corresponding, it is possible to undertaken by latch. Due to when described M coupling device is connected with described M I/O interface, latch have recorded the pin of coupling device corresponding to each interface mark, therefore after the I/O interface that described first coupling device is corresponding is determined in identification, drawing low by pin level corresponding for described N-1 the I/O interface outside a described I/O interface by high level by coding is lower level, thus prevent described N number of I/O interface to be connected with multiple adapter simultaneously, and cause the electric leakage between adapter.
Optionally, in the embodiment of the present invention, while the described break-make connection state of control switches to disconnection state by connection state, it is also possible to comprising: controlling described electronics is power supply state, and control described first coupling device and export the first corresponding adapt voltages. Now, namely so that described first coupling device is described electronics powers, such as, the service voltage of 19V can be exported, it is achieved adapter function of supplying power by a described I/O interface. Meanwhile, described N-1 I/O interface is in the adapter functions that lower level can not respond other coupling device again, only retains USB and connects function.
Therefore in the embodiment of the present invention, the mode firsting impressions are strongest is adopted by latch, by there is described first identification marking the first coupling device by an I/O interface of correspondence and described power supply connection, by coding, level corresponding for other I/O interface pressure is drawn low simultaneously, thus ensure that only retaining an interface in described N number of I/O interface has adapter functions, during to avoid multiple adapter to be connected with described electronics simultaneously, electric leakage between adapter, ensure that the security between electronic equipment interfaces.
