[0039] The following describes some embodiments of the present application in detail with reference to the accompanying drawings. In the absence of conflict, the following embodiments and features in the embodiments may be combined with each other.

[0040] The communication indication circuit is described below with reference to some specific embodiments.

[0041] Figure 1 A framework diagram of a communication indication circuit according to an embodiment of the present application is shown. Exemplarily, the communication indication circuit includes:

[0042] Signal input port 10 , signal conversion module 20 and indication module 30 ; the signal input port 10 is connected to the signal conversion module 20 and the indication module 30 respectively, and the signal conversion module 20 is also connected to the indication module 30 .

[0043] The signal input port 10 is used to connect to the communication device 2, and after the communication device 2 is powered on, the first signal and the second signal transmitted by the communication device 2 are sent to the signal conversion module 20; the signal conversion module 20 is used to output an indication control signal according to the first signal and the second signal; the indication module 30 indicates the transmission status of the communication device 2 according to the indication control signal, and indicates the connection status of the communication device 2 according to the second signal.

[0044] The communication device 2 in this application is an electronic product capable of receiving and transmitting data, such as a switch, a network port, and a computer. The signal input port 10 is an output port for an indication signal on the communication device 2. In this embodiment, there are two signal input ports 10, one of which outputs a second signal, and the other outputs a first signal; the first signal is a square wave signal, and the second signal is a low-level signal.

[0045] For example, see Figure 2 First, when the communication port of the communication device 2 is connected normally, a signal input port 10 of the communication device 2 outputs a low-level second signal (corresponding to Figure 2 When the communication device 2 performs data communication, another signal input port 10 of the communication device 2 outputs a square wave first signal (corresponding to Figure 2 ACT signal in) to the signal conversion module 20.

[0046] Then, the signal conversion module 20 outputs an instruction control signal (corresponding to Figure 2 After the second signal is transmitted to the indication module 30, the indication module 30 indicates the transmission status of the data communication of the communication device 2 according to the indication control signal, for example, using an LED running light to indicate the process of data communication; and the indication module 30 will also indicate the connection status of the communication device 2 according to the second signal, for example, using an LED light to indicate the connection status accordingly.

[0047] It can be understood that in this application, the signal conversion module 20 controls the transmission status of the data communication by the indication module 30 according to the first signal and the second signal transmitted by the signal input port 10 on the communication device 2. The indication module 30 can also indicate the connection status of the communication device 2, thereby improving the intuitive readability and viewing experience of the indication signal, and helping to improve the user experience.

[0048] For example, in one embodiment, the signal conversion module 20 includes: a pull-up unit 21, a filtering unit 22 and a main control unit 23; the main control unit 23 is respectively connected to the pull-up unit 21, the filtering unit 22 and the indication module 30, the pull-up unit 21 is also connected to the signal input port 10, and the filtering unit 22 is also used to connect to the power supply.

[0049] The reset input pin and clock input pin of the main control unit 23 are both connected to the signal input port 10, the reset input pin of the main control unit 23 is also connected to the pull-up unit 21, the positive power pin of the main control unit 23 is connected to the power supply, and the negative power pin and count input pin of the main control unit 23 are both grounded.

[0050] Exemplarily, one of the signal input ports 10 is connected to the reset input pin (low level is valid) of the main control unit 23. Then, when the connection status of the communication port is normal, the communication device 2 outputs a low-level LINK signal (second signal), which lowers the voltage transmitted by the pull-up unit 21, so that the MR pin of the main control unit 23 is a low-level signal. At this time, the indication module 30 directly indicates that the connection status of the communication device 2 is a normal connection status.

[0051] In addition, another signal input port 10 in the signal input port 10 is connected to the clock input pin (rising edge triggered) of the main control unit 23. Then, when the communication port transmits data, the communication device 2 outputs a square wave ACT signal (first signal), that is, the ACT signal on the CP0 pin is a square wave signal. At this time, the main control unit 23 outputs a high-level indication control signal to the indication module 30 in sequence according to the low-level LINK signal and the square wave ACT signal, so that the indication module 30 indicates that the data communication of the communication device 2 is in a normal transmission state according to the high-level indication control signal.

[0052] For example, see also Figure 3 In one embodiment, the main control unit 23 includes: a counter chip U1.

[0053] The positive power pin of the counter chip U1 (corresponding to Figure 3 The VDD of the counter chip U1 is connected to the pull-up unit 21, and the negative power supply pin of the counter chip U1 (corresponding to Figure 3 VSS of the counter chip U1) and the counting input pin (corresponding to Figure 3 The / CP1 of the counter chip U1 in the middle is grounded; the clock input pin of the counter chip U1 (rising edge trigger, corresponding to Figure 3 The CP0 of the counter chip U1 is connected to the first port 11 of the signal input port 10 to receive the first signal.

[0054] The reset input pin of the counter chip U1 is connected to the pull-up unit 21 and the second port 12 in the signal input port 10 respectively to receive the second signal. The count pulse output pin of the counter chip U1 (corresponding to Figure 3 Q1 to Q9 of the counter chip U1 are connected to the indication module 30 .

[0055] In this embodiment, the counter chip U1 includes CD4017. In another embodiment of the present application, the counter chip U1 can be replaced by a CPLD (Complex Programmable Logic Device) to achieve the same functions as the counter chip U1.

[0056] Exemplarily, one of the signal input ports 10 (the second port 12) is connected to the reset input pin of the counter chip U1. Then, when the communication port is in a link-disconnected state, that is, the communication port is unplugged and the second port 12 cannot access the second signal, the MR pin pulls up the LINK signal due to the voltage transmitted by the pull-up unit 21. At this time, the counter chip U1 starts to reset. Then, the counting pulse output pins all output low-level indication control signals to the indication module 30. At this time, the indication module 30 is in an abnormal working state and cannot indicate the data transmission status and connection status of the communication device 2.

[0057] However, when the communication port is in the normal link state, the communication device 2 outputs the second signal ( Figure 3 LINK signal), at this time, the MR pin of the main control unit 23 is a low level signal, indicating that the module 30 is working normally, indicating that the connection status of the communication device 2 is a normal connection status.

[0058] Furthermore, when the communication port of the communication device 2 is transmitting data, that is, when the first port 11 receives the square wave ACT signal to the CP0 pin, the counter chip U1 outputs a high-level indication control signal to the indication module 30 in sequence based on the square wave ACT signal and the low-level LINK signal, so that the indication module 30 indicates that the data communication of the communication device 2 is in a normal transmission state.

[0059] Furthermore, in another embodiment of the present application, if the LINK signal output by the communication device 2 is high by default, the LINK can be set to a low level through corresponding software or hardware configuration, or an inverter can be added to the reset input pin.

[0060] For example, in one embodiment, the indication module 30 includes: a first indication unit 31 and a second indication unit 32; the first indication unit 31 is connected to the main control unit 23, and the second indication unit 32 is connected to the signal input port 10; the second indication unit 32 is also used to connect to the power supply; the first indication unit 31 is used to indicate the transmission status of the communication device 2; the second indication unit 32 is used to indicate the connection status of the communication device 2.

[0061] Exemplarily, when the LINK signal is low, the second indication unit 32 indicates that the connection status of the communication device 2 is normal based on the low-level LINK signal. Simultaneously, when the ACT signal is a square wave signal, the counter chip U1, based on the low-level LINK signal and the square-wave ACT signal, sequentially outputs high-level indication control signals from the multiple counting pulse output pins of the counter chip U1 to the first indication unit 31. The first indication unit 31 then indicates that the transmission status of the communication device 2 is normal.

[0062] For example, in one embodiment, the pull-up unit 21 is a pull-up resistor R1 ; one end of the pull-up resistor R1 is connected to the reset input pin and the second port 12 , respectively, and the other end of the pull-up resistor R1 is connected to the power supply.

[0063] The pull-up resistor R1 is used to ensure that the MR pin is kept at a high level when the LINK signal is idle or low.

[0064] For example, in one embodiment, the filtering unit 22 includes: a filter capacitor C1; one end of the filter capacitor C1 is connected to the positive power pin of the counter chip U1 and the power supply, respectively, and the other end of the filter capacitor C1 is grounded.

[0065] For example, see also Figure 4 In one embodiment, the second indicating unit 32 includes: a second current limiting resistor R2 and a second diode LED1 (corresponding to Figure 2 the anode of the second diode LED1 is connected to the power supply, the cathode of the second diode LED1 is connected in series with the second current limiting resistor R2 and then connected to the second port 12 in the signal input port 10.

[0066] The second diode LED1 is a light emitting diode; the second current limiting resistor R2 is used to protect the second diode LED1.

[0067] For example, in one embodiment, the first indication unit 31 includes: a plurality of first diodes and a first current-limiting resistor equal to the number of the first diodes; the positive electrode of each first diode is connected to the corresponding counting pulse output pin of the counter chip U1, and the negative electrode of each first diode is connected in series with the corresponding first current-limiting resistor and then grounded.

[0068] Wherein, the first diodes are all light emitting diodes.

[0069] For example, the counter chip U1 in this application has 10 counting pulse output pins ( Figure 3(represented by Q0~Q9 in the figure), except for the first counting pulse output pin, each counting pulse output pin is connected in series with a first diode and a first current-limiting resistor and then grounded. In the embodiment of the present application, 9 first diodes (corresponding to the number of counting pulse output pins of the counter chip U1) and 9 first current-limiting resistors are included. In order to facilitate distinction, the 9 first diodes are respectively labeled as: 1st diode LED2, 1st diode LED3, 1st diode LED4, 1st diode LED5, 1st diode LED6, 1st diode LED7, 1st diode LED8, 1st diode LED9, 1st diode LED10; the 9 first current-limiting resistors are respectively labeled as: 1st current-limiting resistor R3, 1st current-limiting resistor R4, 1st current-limiting resistor R5, 1st current-limiting resistor R6, 1st current-limiting resistor R7, 1st current-limiting resistor R8, 1st current-limiting resistor R9, 1st current-limiting resistor R10, 1st current-limiting resistor R11.

[0070] In order to better understand the present invention, the following Figure 3 and Figure 4 The working principle of the communication indication circuit 1 of the present utility model is described in detail:

[0071] See also Figure 3 and Figure 4 In the embodiment of the present application, the communication device 2 is used as a network port, and the first port 11 and the second port 12 are directly present in the network port. First, the ACT signal transmitted by the first port 11 of the network port is connected to the clock input pin of CD4017 (counter chip U1) (in Figure 3 CP0 is used in the code, and the rising edge of CP0 pin triggers the counter to count according to the rising edge of CP0 pin). Connect the LINK signal transmitted by the second port 12 of the network port to the reset input pin of CD4017 (in Figure 3 MR is used in the figure, and the MR pin is valid at low level) and is connected to the power supply ( Figure 3 and Figure 4 VCC in the table), the counter clock input pin of CD4017 (i.e. the counting input pin, Figure 3 / CP1 is used to indicate that the / CP1 pin is valid at low level, that is, when the counter outputs counting pulses, the / CP1 pin must be at low level) and connected to the signal ground.

[0072] In addition, 9 of the counting pulse output pins of CD4017 (in Figure 3 Each pin is connected to an LED lamp (i.e., the first diode) and a current limiting resistor (i.e., the first current limiting resistor) and then to ground (the 9 first diodes are connected to the ground). Figure 4In the figure, LED2-LED10 are used to represent the 9 first current limiting resistors. Figure 4 The LINK signal is also connected to an LED lamp (i.e., the second diode LED1) in reverse connection and a current limiting resistor (i.e., the second current limiting resistor R2) before being connected to the power supply.

[0073] Then, when the network port is disconnected, that is, the second port 12 has no signal output, because the MR pin is connected to the power supply through the pull-up resistor R1, the MR pin is pulled high. According to the characteristics of CD4017, the output of Q1 to Q9 is low, and all the LED lights connected to them are off. At the same time, because the LINK signal is high at this time, the second diode LED1 is also off.

[0074] However, when the connection status of the network port is normal, the second port 12 of the network port outputs a low-level LINK signal. At this time, the MR pin is pulled down to a low level, so the second diode LED1 is lit, and whether it is a normal connection status can be indicated according to the on and off status of the second diode LED1.

[0075] Furthermore, when the network port connection is normal and communication data is being forwarded, the ACT signal output by the first port 11 is a square wave signal. According to the characteristics of the CD4017, the CP0 pin is rising-edge triggered, and the MR pin is valid at a low level. Therefore, when the ACT signal changes from low to high, the CD4017 is triggered to count, that is, Q1 of the CD4017 outputs a high level. Then, on the next rising edge of the ACT signal, the count is triggered again, that is, Q2 outputs a high level. And so on, eventually, Q1 to Q9 output high levels in sequence, thus achieving a running light or marquee effect.

[0076] An embodiment of the present application provides a communication device, including a PCB board, on which the communication indication circuit 1 as described above is provided; since the communication indication circuit 1 has been described in detail above, it will not be repeated here.

[0077] The communication equipment includes a switch or a router.

[0078] The above is only a specific implementation method of the present application, but the scope of protection of the present application is not limited thereto. Any technician familiar with this technical field can easily think of changes or replacements within the technical scope disclosed in this application, which should be covered by the scope of protection of the present application.
