the physical ports are multiple physical ports of the same type (for example, all network ports), or multiple physical ports of different types (physical ports may include, but are not limited to, network ports, USB ports, and voice ports); for example, if the port numbered L2 is detected to be inserted, a virtual information group (I, L2) is generated, wherein I represents the port insertion;
when the physical port is a plurality of physical ports of different types, the virtual information group further comprises a physical port type; for example, the physical port types of the network port, USB port, and voice port are numbered as C1, C2, and C3, respectively; generating a virtual information group (C1, I, L2) if the network port numbered L2 is detected to be inserted;
further, the plugging and unplugging state of the physical port is as follows: physical port insertion signals or physical port extraction signals;
namely, when the physical port is inserted, the physical port is defined as a physical port insertion signal I, and when the physical port is pulled out, the physical port is defined as a physical port pulling-out signal O;
or further, the physical port insertion signal includes an instant insertion state, or a physical port insertion sub-signal generated according to a physical port insertion duration;
that is, when a physical port is plugged in, various plugging states are generated in combination with the timing signal, for example, when the physical port is plugged in, it is defined as a physical port plugging sub-signal I, and the timing generator is started, and the time period t can be set to 1 second.

Example 2
Fig. 2 is a flowchart of a method for implementing a virtual key of a home gateway in an embodiment of the present invention, where the flow of the method for implementing a virtual key includes:
s101, defining a virtual information group, a virtual information group sequence and a virtual key of the home gateway.
According to the use scene of the virtual key system of the gateway equipment, the type and the number of a physical port are defined, and a virtual information group corresponding to each physical port in a plugging state is defined.
And predefining virtual information group sequences corresponding to different virtual keys and functions corresponding to the virtual keys. The set of virtual information includes, but is not limited to, a physical port type, a physical port number, and a physical port plug signal.

The user controls the change of the plugging signal of the physical port of the device through plugging action (further combining with plugging duration).
S103, detecting a physical port plugging signal.
The states mainly include two states of insertion IN and extraction OUT.
Furthermore, besides detecting the plug-in and plug-out states of the ports in time, a time sequence generator can be additionally used for assisting in detecting the physical port plug-in and plug-out signals which deviate along with time.
When insertion is detected, the timing generator is turned on.
When a pull-out is detected, the timing generator is turned off.
The periodic signal of the timing generator can trigger again whether the detection port is in the insertion state. That is, in the whole insertion duration process, the port is detected whether to be in an insertion state or not by a periodic signal of the timing generator for a plurality of times, so that the insertion duration process is expanded into a plurality of insertion physical port insertion sub-signals.
Fig. 3 is a timing diagram illustrating a physical port plugging signal detection according to an embodiment of the invention.
When a physical port is inserted, an insertion signal I is detected. The timing generator is started simultaneously and the time period t can be set to 1 second.
When the physical port is unplugged, the unplugging signal O is detected. While turning off the timing generation signal.
When the 1 time period signal is received, the insertion signal I1 is detected.
When the 3 time period signal is received, the insertion signal I2 is detected.
And S104, generating a virtual information group according to the detected physical port type, the physical port plugging signal and the physical port number.
And S105, driving the virtual key state machine to generate a virtual key by the virtual information group.
The virtual key state machine transitions the state within the set timeout T based on the set of virtual information received from S104. Each state of the virtual key state machine is composed of a plurality of virtual information groups generated by one-time plugging and unplugging action of the physical port.
If the state transition time T is exceeded, a Timeout signal Timeout is received, the Timeout state is entered, log information is recorded, and the state is recovered to the initialization state; if the state is transferred to an undefined state, recording the log information and restoring to an initialized state; and if the state is transferred to the virtual key definition state, recording the log information, sending corresponding virtual key information to the key execution module, and returning to the initialization state again. And the state machine is transferred to a new state every time, and the count of the overtime timer is cleared. If the Timeout timer exceeds the state transition time T, a Timeout signal Timeout is sent to the state machine. The state machine closes the timeout timer in the INIT state.
When the virtual key state machine sends the state transition, the user can be prompted through the alarm module, and the virtual key detection is carried out.
In step 106, the function of the virtual key is executed and log information is recorded.
The virtual key sent in step S105 is buffered using the first-in first-out queue.
Further, the virtual key defined in step S101 may also be retrieved. And if the corresponding virtual key is retrieved, executing the corresponding key task and recording log information. And if the corresponding virtual key cannot be retrieved, ignoring the virtual key and recording log information.
Example 4
As shown in FIG. 4, the physical port names are IF1(Interface1), IF2(Interface2), IF3(Interface3), and IF4(Interface4), respectively. In order to better manage the port physical port plugging and unplugging signals, the names of the physical ports can be virtualized into physical port numbers according to a specific sequence. For example: physical port number L1 for IF1, physical port number L2 for IF2, physical port number L3 for IF3, and physical port number L4 for IF 4; alternatively, the physical ports may be virtually encoded in other orders. The physical ports may include, but are not limited to, network ports, USB ports, and voice ports, and the physical port types of the network ports, the USB ports, and the voice ports may be numbered as C1, C2, and C3, respectively.
A virtual information group (C1, I, L2) is generated IF a network port named IF2 is detected to be plugged in, and a virtual information group (C1, O, L2) is generated IF a network port named IF2 is detected to be unplugged.
The virtual information set can be deleted or added on the basis. For example, the [ (C1, I, L2) (C1, O, L2) ] virtual information group can be optimally represented as [ (C1, L2) ] according to the usage scenario. Further, in the scenario of not distinguishing the physical port types, it can be sub-optimized to [ (L2) ] virtual information group.
Example 5

and Reset: the home gateway restores the factory settings, and the virtual information group sequence of the Reset virtual key can be defined as: (C1, I, L1) (C1, O, L1) (C1, I, L2) (C1, O, L2) (C1, I, L2) (C1, O, L2) (C1, I, L3) (C1, O, L3). Generally stated, virtual key Reset is activated by plugging in and out the IF1, IF2, IF2 and IF3 ports in sequence. If a physical port plugging signal I1 is introduced (i.e. a physical port plugging sub-signal generated by a timing generator according to a physical port plugging duration), each plugging action is completed within a time period T of the timing generator, otherwise, each action is completed within a state expiration time T.
WebLock: the user self-defines a virtual key WebLock, and the virtual information group sequence of the key can be defined as: (C1, I, L3) (C1, O, L3) (C1, I, L2) (C1, O, L2) (C1, I, L4) (C1, O, L4). Generally stated, virtual key WebLock is activated by plugging in and out the IF3, IF2 and IF4 ports in sequence. If a physical port plugging signal I1 is introduced, each plugging action is completed within a time period T of the timing generator, otherwise, each action is completed within a state expiration time T.
Different virtual information group sequences can be combined by referring to the content defined by the physical port plugging signal. The virtual information group sequence can further define the virtual key and map to a specific execution function, thereby completing the definition of the virtual key data model.
