Referring to fig. 1, fig. 1 is a schematic structural diagram of a network port switching device provided in this embodiment, where the network port switching device includes: a controller 11, a switch chip 12, a first network port 131 and a second network port 132;
the controller 11 is electrically connected to the first network port 131, the second network port 132 and the switching chip 12 respectively;
the controller 11 includes a first input pin and a second input pin, the first input pin is electrically connected to the first network port 131, and the second input pin is electrically connected to the second network port 132;
the controller 11 is configured to receive a first level signal from the first network port 131 through the first input pin, receive a second level signal from the second network port 132 through the second input pin, generate a control signal according to the first level signal and the second level signal, and control the switching chip 12 to be electrically connected to the first network port 131 or the second network port 132 according to the control signal.
Specifically, the first Input pin and the second Input pin of the controller 11 may be GPIO (General Purpose Input/Output Port) pins, that is, General Purpose Input/Output Port pins. When the GPIO is used as an input port, the state of the pin, i.e., high level or low level, can be read in through it, and when the GPIO is used as an output port, the connected peripheral device can be controlled by outputting high level or low level through it. Referring to fig. 1, in the present embodiment, the first input pin may be named GPIO1, and the second input pin may be named GPIO 2.
The function of the GPIO pin may be configured by a register, for example, a read/write function for the GPIO pin may be implemented by a port data register, and when the GPIO pin is set to be input, reading the register may obtain whether the level state of the corresponding GPIO pin is high or low; when a GPIO pin is set to output, the corresponding GPIO pin can be set to output either a high level or a low level by writing the corresponding bit of this register.
In this embodiment, two GPIO pins, that is, GPIO1 and GPIO2, are provided in the controller 11 as general-purpose inputs, so that the GPIO1 is electrically connected to the first network port 131, and the GPIO2 is electrically connected to the second network port 132. The controller 11 may obtain the level states of the GPIO1 and the GPIO2, that is, the level states of the first network port 131 and the second network port 132 respectively output to the corresponding electrically connected GPIO1 and GPIO2, through the port data register.
It should be noted that the first network port 131 and the second network port 132 may be the same type of network port, and the structure and function of the first network port 131 and the second network port 132 may also be the same. The function of the first portal 131 will be described below in connection with its composition.
In this embodiment, the first network port 131 includes:
in a specific embodiment, the first port 131 includes: a first elastic sheet 1311, a second elastic sheet 1312, a first control pin 1313 and a second control pin 1314;
the first elastic sheet 1311 is connected to the first control pin 1313, and the second elastic sheet 1312 is connected to the second control pin 1314.
Specifically, please refer to fig. 3. As shown in fig. 3, the first network port 131 is formed by adding two elastic pieces and two pins in a standard RJ45 standard network port, wherein the two elastic pieces are a first elastic piece 1311 and a second elastic piece 1312 respectively. The two pins are at the bottom of the first portal 131 and are therefore not shown in fig. 3. Referring to fig. 4, as shown in fig. 4, the first network port further includes a first control pin 1313 and a second control pin 1314. In the first network port 131, the first elastic piece 1311 is connected to the first control pin 1313, and the second elastic piece 1312 is connected to the second control pin 1314.
In addition, in this embodiment, the first network port 131 is further externally connected with a circuit, and the connection relationship between the first network port 131 and the circuit is:
referring to fig. 4, in a specific embodiment, the apparatus further includes a first power supply VCC1 and a first resistor R2;
the first control pin 1313 is grounded via the first resistor R1, the first control pin 1313 is electrically connected to the first input pin, and the second control pin 1314 is electrically connected to the first power VCC 1.
Specifically, referring to fig. 4, the external circuit includes a first power VCC1 and a first resistor R1, the first control pin 1313 is grounded via the first resistor R1, and the first control pin is electrically connected to the GPIO 1. The second control pin 1314 is coupled to a first power supply VCC 1.
The function realized after the first network port 131 is connected with the external circuit is as follows:
when a network cable is inserted into the first network port 131, the first elastic sheet 1311 deforms and contacts with the second elastic sheet 1312, so that the first control pin 1313 contacts with the second pin 1314, at this time, the external circuit is connected, the first control pin 1313 outputs a high level to the GPIO1, and the controller 11 can determine that the network cable is inserted into the first network port 131 by acquiring the high level input by the GPIO 1. Or, when no network cable is inserted into or pulled out of the first network port 131, the external circuit is turned off, the first control pin 1313 is grounded through the first resistor, and the first control pin 1313 outputs a low level to the GPIO 1. The controller 11 may determine that the first network port 131 has no network cable inserted by acquiring the low level of the GPIO 1.
It should be noted that, in this embodiment, the external circuit connected to the second network port 132 may be the same as the external circuit connected to the first network port 131, and the function realized after the second network port 132 is connected to the external circuit is the same as the function realized by the first network port 131, that is, the first network port 131 and the second network port 132 both have a level output function, and the controller 11 may determine the network cable insertion condition of the first network port 131 and the second network port 132 according to the high and low levels output by the first network port 131 and the second network port 132, so as to serve as a basic condition for subsequently switching the network ports.
The first network interface 131 and the second network interface 132 with the level output function provided in this embodiment may also be implemented based on a non-standard network cable interface, for example, for a non-standard network cable and a network cable interface with ten pins, eight of the pins may be used as a standard network cable, the other two pins may be respectively used to connect an external power supply and a GPIO pin of the controller 11, and the level output function may be implemented by setting two elastic pieces in the network cable interface. For a specific setting process, please refer to the specific process of setting the first network port 131 with the level output function based on the RJ45 standard network cable interface, which is not described herein again to avoid repetition.
The controller 11 may obtain a network cable insertion state of the network port correspondingly connected to the GPIO pin through a high-low level state of the GPIO pin, so as to be used as a basis for controlling network port switching. In this embodiment, the controller is further provided with a GPIO pin as an output port. Referring to fig. 1, a GPIO pin as an output port may be named GPIO3, GPIO3 is electrically connected to the switching chip 12, and a high-low level is output to the switching chip 12 through the GPIO3 to control the switching chip 12 to implement switching of a network port through its switching function.
Therefore, the controller 11 outputs high and low levels, so that the switching chip 12 can be controlled to switch the network ports, and the network cables do not need to be plugged and pulled manually, so that the network ports are more convenient to replace. And moreover, the switching use of two network ports can be met by only arranging one communication line, the uniqueness of the communication line is ensured, and the economic cost is reduced.
In the present embodiment, the model of the switching chip 12 is TS3L4892 RHHR. When the switching chip 12 of the type is used, the specific level switching relationship is as follows: when a low level is input, the communication is switched to the first port 131, and when a high level is input, the communication is switched to the second port 132. In practical applications, the switching chip 12 may also be other chips with switching functions, and the specific level switching relationship may be determined according to the actually selected chip. For example, the level switching relationship may be such that when a low level is input, the communication is switched to the second port 132, and when a high level is input, the communication is switched to the first port 131. The selection is performed according to actual requirements, and is not limited herein.
In this embodiment, the specific switching process of the network port includes:
when the first network port 131 and the second network port 132 are both plugged with network cables, the first network port 131 and the second network port 132 respectively output high levels to the GPIO1 and the GPIO2, and at this time, the controller 11 acquires information that the first network port 131 and the second network port 132 are both plugged with network cables through the built-in port data register, and realizes priority communication of the network ports with high priority according to the preset priority of the network ports.
For example, in a specific embodiment, when the first port 131 and the second port 132 are plugged with network cables and the preset priority of the first port 131 is higher than the priority of the second port 132, the controller 11 outputs a corresponding level signal to the switching chip 12 through the GPIO1 to control the switching chip 12 to switch the communication to the first port 131 with a higher priority. The corresponding level signal output by the GPIO1 may be determined according to the level switching relationship of the switching chip 12. The priority of the network port can be preset through a program in the controller, and the priority can be set according to the actual use requirement of each network port, which is not limited herein.
It should be noted that, in an alternative example, when only one portal is plugged with a network cable, the communication of the current portal is directly performed. For example, when the first port 131 has a network cable inserted therein and the second port 132 has no network cable inserted therein, the first port 131 inputs a high level to the GPIO and the second port 132 inputs a low level to the GPIO 2. At this time, the controller 11 determines that the first network port 131 has the network cable inserted information through the GPIO1 and the high-low level state of the GPIO2, and outputs the low level to the switching chip 12 through the GPIO3 to control the switching chip 12 to switch to the first network port 131, so as to implement the communication through the first network port 131.
Through the net gape auto-change over device that this embodiment provided, the switching that can carry out the net gape when two net gapes all have the net twine to guarantee communication line's uniqueness, simultaneously, also satisfied the switching use of a communication line between two net gapes, the cost is reduced. In addition, the communication requirement when a single network port is inserted into a network cable can be met, and the practicability is high.
In a specific embodiment, the controller 11 further includes a third output pin;
the third output pin is electrically connected to the switching chip 12, and is configured to output the control signal to the switching chip 12.
Specifically, the third output pin is the GPIO3, and the control signal may be at a high level or a low level. And outputting a high level or a low level to the switching chip 12 through the GPIO3 to implement a switching function of the switching chip 12, so as to implement communication switching of the first network port 131 or the second network port 132.
In a specific embodiment, the switching chip 12 includes a switching pin;
the switching pin is electrically connected with the third output pin and is used for receiving the control signal from the third output pin.
Specifically, the switching chip 12 is a chip with a switching function, the switching function is realized by a selection function of the 27 pins, and the 27 pins may be defined as the switching pins. The GPIO3 of the controller 11 is electrically connected to the pin 27, and a high level or a low level is input to the pin 27 through the GPIO3, so that a selection function of the pin 27 is realized. The 27 pin selection functions include: the communication selection is switched to the first portal 131 or the second portal 132.
Therefore, the switching function of the switching chip 12 is achieved according to the selection function of the 27 pins, so that the switching use of one communication line on two network ports can be realized, the economic cost is reduced, and the convenience degree of switching the network ports is higher.
