Description

TECHNICAL FIELD

[0001] Embodiments of the present disclosure relate to the field of communication technology, and in particular, to a control circuit and a control method of an optical-electric multiplexing interface indicator light, and a network device. BACKGROUND

[0002] In the 21st century, with the rapid development of informationization construction and IT technology, various network technologies are more widely and deeply applied, and the application of field network ports is also more diversified, resulting in higher requirements for network device network ports. A network device containing both an electrical port and an optical port or an optical-electric multiplexing interface (Combo network port) is becoming more and more popular. The Combo network port is a network interface that can output both an electrical port and an optical port at the same time, but only one interface can be used at the same time. When the electrical port is connected, the optical port will be in an unusable state, and vice versa. The Combo network port improves the flexibility and diversity of network devices in application fields.

[0003] Although the Combo network port has many benefits, the Combo network port indicator light is often difficult to handle. The physical layer chip (PHY chip) supporting the Combo network port often has only 3 signals left for indicator light control because it needs to output both electrical port signals and optical port signals. If not handled properly, it may result in signal state loss or overly complex Combo network port indicator light control circuit.

[0004] The existing Combo network port indicator light control mainly has the following two kinds: the first kind, the electrical port retains two indicator lights, which are single-color linkact and single-color speed, and the speed single-color indicates gigabit; the optical port retains a single-color linkact indicator light; the second kind, the electrical port retains two indicator lights, which are single-color linkact and double-color speed, and the speed double-color can indicate gigabit or hundred megabit; the optical port retains a single-color linkact indicator light. The indicator light control circuit cannot be output by the PHY chip, and an external MCU or CPLD is needed to detect and control.

[0005] For the above two cases, the inventors found that in the first case, the electrical port speed indicator light cannot be obviously indicated by color change whether the current network port is in 1G state or 100M / 10M state. When connecting to other network devices in the application field, the network port and the opposite network port may exhibit different indicator light states, which may cause confusion to application engineers. In addition, in the second case, although the electrical port and optical port indicator lights can basically meet the application, an external MCU or CPLD is needed to detect and control the circuit, which is complex to implement, needs real-time detection and control, involves single-chip microcomputer and main CPU network port state synchronization, logic analysis, and real-time control. The workload is large, the cost investment is large, and the real-time effect is difficult to control.

[0006] In summary, how to propose a more simple and can satisfy the actual application requirements of the light indicator control mode is an urgent need to solve. SUMMARY

[0023] In order to make the objects, technical solutions and advantages of the embodiments of the present disclosure clearer, the technical solutions of the embodiments of the present disclosure will be described clearly and completely below with reference to the drawings.

[0025] In all embodiments of the present disclosure, terms such as "first" and "second" are only used to distinguish one component (or part of a component) from another component (or another part of a component).

[0026] In order to solve the problems of existing optical-electrical multiplexing interface indicator light control methods, such as complex implementation, high cost, or not meeting the actual application of electrical and optical ports, a new optical-electrical multiplexing interface indicator light control method is proposed. The optical-electrical multiplexing interface indicator light control method of the embodiments of the present disclosure is simple to implement and can meet the actual application of electrical and optical ports. The optical-electrical multiplexing interface indicator light control method of the present disclosure will be described in detail below.

[0027] Figure 1 A schematic circuit diagram of a control circuit 100 of an optical-electrical multiplexing interface indicator light of the embodiments of the present disclosure is shown. In addition, Figure 1 A schematic diagram of a physical layer chip PHY and an optical-electrical multiplexing interface Combo is also shown in FIG. 1, wherein the optical-electrical multiplexing interface Combo includes an electrical interface (electrical port) A and an optical interface (optical port) B, such as Figure 1As shown, the control circuit 100 for the optoelectronic multiplexing interface indicator includes: an optoelectronic differentiation module 110, a first indicator 120, a second indicator 130, and a third indicator 140.

[0028] The photoelectric differentiation module 110 is coupled to the physical layer chip PHY, the first indicator light 120, the second indicator light 130, and the third indicator light 140. The photoelectric differentiation module 110 is configured to receive the first control signal LED1, the second control signal LED2, and the third control signal LED3 emitted by the physical layer chip PHY, and to generate an electrical port connection indication signal T2 and an optical port connection indication signal T3 to distinguish between electrical interface A and optical interface B. The first control signal LED1 is a signal responding to the first rate state of electrical interface A, and the second control signal LED2 is a signal responding to the second rate state of electrical interface A. The signal responding to the first rate state of electrical interface A indicates the first rate connection (link) state of electrical interface A; that is, when the link state of electrical interface A is at the first rate, the first control signal LED1 changes from low to high. Similarly, the signal responding to the second rate state of electrical interface A indicates the second rate connection (link) state of electrical interface A; that is, when the link state of electrical interface A is at the second rate, the second control signal LED2 changes from low to high. Typically, the first data rate can be 10M / 100M, and the second data rate can be 1G. The third control signal LED3 is a signal that responds to the connectivity status of optical interface B and electrical interface A. The connectivity status includes a linked state (link) and an active state (act). That is, when optical interface B or electrical interface A is linked, the third control signal LED3 will change from low level to high level. When there is data transmission (act) on optical interface B or electrical interface A, the third control signal LED3 will switch between high and low levels.

[0029] The first indicator light 120 is located on the side of electrical interface A. Figure 1 The monochrome indicator light (left side) is configured to receive the electrical port connection indication signal T2 and control the on / off state of the first indicator light 120 according to the level state of the electrical port connection indication signal T2. Further, the first indicator light 120 is a monochrome link / act indicator light, and the first indicator light 120 includes a first diode VD1. Specifically, controlling the on / off state of the first indicator light 120 according to the level state of the electrical port connection indication signal T2 includes: if the electrical port connection indication signal T2 is high, then controlling the first diode VD1 to light up; if the electrical port connection indication signal T2 is low, then controlling the first diode VD1 to turn off.

[0030] The second indicator light 130 is located on the other side of electrical interface A. Figure 1The second indicator lamp 130 is a double-color lamp arranged on the right side of the optical-electric multiplexing interface Combo, configured to receive the first control signal LED1 and the second control signal LED2, and control the on-off of the second indicator lamp 130 according to the level state of the first control signal LED1 and the level state of the second control signal LED2. Further, the second indicator lamp 130 is a double-color speed indicator lamp, including a third diode VD3 and a fourth diode VD4 of different light-emitting colors, which indicate different speeds by different colors (such as green and yellow). Specifically, the control of the on-off of the second indicator lamp 130 according to the level state of the first control signal LED1 and the level state of the second control signal LED2 includes: if the first control signal LED1 is high and the second control signal LED2 is low, the third diode VD3 is controlled to be on; if the second control signal LED2 is high and the first control signal LED1 is low, the fourth diode VD4 is controlled to be on; and if the first control signal LED1 and the second control signal LED2 are both low, the third diode VD3 and the fourth diode VD4 are both controlled to be off.

[0031] The third indicator lamp 140 is a single-color lamp arranged on the side of the optical interface B (the left side in the figure), Figure 1 The third indicator lamp 140 is a single-color lamp arranged on the side of the optical interface B (the left side in the figure), Figure 1 The third indicator lamp 140 is a single-color lamp arranged on the side of the optical interface B (the left side in the figure),

[0032] From the above description, it can be seen that the control circuit 100 of the optical-electric multiplexing interface Combo indicator lamp in the embodiment of the present disclosure controls the double-color lamp on the side of the electrical interface A by responding to the first control signal LED1 of the first speed state of the electrical interface A and the second control signal LED2 of the second speed state of the electrical interface A, to realize the indication of distinguishing different speeds; and the third control signal LED3 capable of simultaneously supporting the connection state of the optical interface B and the connection state of the electrical interface A is converted by the optical-electric distinguishing module 110 to obtain the electrical port connection indication signal T2 and the optical port connection indication signal T3 capable of distinguishing the connection of the electrical interface A or the optical interface B, and then the single-color lamp on the side of the electrical interface A and the single-color lamp on the side of the optical interface B are controlled according to the electrical port connection indication signal T2 and the optical port connection indication signal T3, respectively. Compared with the existing control mode of the optical-electric multiplexing interface Combo indicator lamp, the control mode of the optical-electric multiplexing interface Combo indicator lamp in the embodiment of the present disclosure can not only meet the actual application of the electrical port and the optical port, but also has a simple structure and is easy to control.

[0033] Furthermore, such as Figure 1 As shown, the photoelectric differentiation module 110 includes: an OR gate, a first AND gate AND1, a second AND gate AND2, and a NOT gate. The first input terminal of the OR gate OR is coupled to a first control signal LED1, the second input terminal of the OR gate OR is coupled to a second control signal LED2, and the output terminal of the OR gate OR (the output signal of the OR gate OR in the figure is T1) is coupled to the first input terminal of the first AND gate AND1 and the input terminal of the NOT gate, respectively. The second input terminal of the first AND gate AND1 is coupled to a third control signal LED3, and the output terminal of the first AND gate AND1 outputs an electrical port connected to an indicator signal T2. The first input terminal of the second AND gate AND2 is coupled to the output terminal of the NOT gate NOT, the second input terminal of the second AND gate AND2 is coupled to the third control signal LED3, and the output terminal of the second AND gate AND2 outputs an optical port connected to an indicator signal T3.

[0034] Furthermore, such as Figure 1 As shown, the positive terminal of the first diode VD1 is coupled to the electrical port and connected to the indicator signal T2; the positive terminal of the second diode VD2 is coupled to the optical port and connected to the indicator signal T3; the negative terminals of both the first and second diodes are coupled to the ground terminal GND; the positive terminal of the third diode VD3 is coupled to the first control signal LED1; the negative terminal of the third diode VD3 is coupled to the second control signal LED2; the positive terminal of the fourth diode VD4 is coupled to the second control signal LED2; and the negative terminal of the fourth diode VD4 is coupled to the first control signal LED1.

[0035] Combination Figure 1 The working principle of the control circuit 100 of the photoelectric multiplexing interface Combo indicator in this embodiment is explained: The connection state of the photoelectric multiplexing interface Combo can be divided into the following four types.

[0036] The first scenario: When the electrical interface A is connected to the first speed, the physical layer chip PHY responds and outputs the first control signal LED1, which changes from low to high. The second control signal LED2 remains low, and the third control signal LED3 changes from low to high. At this time, the first control signal LED1 is high, causing the third diode VD3 to light up. The second control signal LED2 is low, causing the fourth diode VD4 to turn off. Simultaneously, the logic circuit in the photoelectric differentiation module 110 shows that when the first control signal LED1 is high, the second control signal LED2 is low, and the third control signal LED3 is high, the electrical port connection indicator signal T2 is high, and the optical port connection indicator signal T3 is low. Therefore, the first indicator light 120 coupled to the electrical port connection indicator signal T2 lights up, and the third indicator light 140 coupled to the optical port connection indicator signal T3 turns off.

[0037] The second kind: the electric interface A connects the second speed, then the second control signal LED2 outputted by the physical layer chip PHY after the response changes from low level to high level, the first control signal LED1 is low level, and the third control signal LED3 changes from low level to high level, at this time, the second control signal LED2 is high level, the fourth diode VD4 is bright, the first control signal LED1 is low level, and the third diode VD3 is off; meanwhile, the logic circuit in the photoelectric area distinguishing module 110 can obtain that when the second control signal LED2 is high level, the first control signal LED1 is low level, and the third control signal LED3 is high level, the electric port connection indicating signal T2 is high level, and the optical port connection indicating signal T3 is low level, therefore, the first indicating lamp 120 coupled with the electric port connection indicating signal T2 is bright, and the third indicating lamp 140 coupled with the optical port connection indicating signal T3 is off.

[0038] The third kind: the optical interface B connects, then the first control signal LED1 outputted by the physical layer chip PHY after the response is low level, the second control signal LED2 is low level, and the third control signal LED3 changes from low level to high level, at this time, the first control signal LED1 is low level, the third diode VD3 is off, the second control signal LED2 is low level, and the fourth diode VD4 is off; meanwhile, the logic circuit in the photoelectric area distinguishing module 110 can obtain that when the first control signal LED1 is low level, the second control signal LED2 is low level, and the third control signal LED3 is high level, the electric port connection indicating signal T2 is low level, and the optical port connection indicating signal T3 is high level, therefore, the first indicating lamp 120 coupled with the electric port connection indicating signal T2 is off, and the third indicating lamp 140 coupled with the optical port connection indicating signal T3 is bright.

[0039] The fourth kind: neither the optical interface B nor the electric interface A connects, then the first control signal LED1 outputted by the physical layer chip PHY after the response is low level, the second control signal LED2 is low level, and the third control signal LED3 is also low level, at this time, the first control signal LED1 is low level, the third diode VD3 is off, the second control signal LED2 is low level, and the fourth diode VD4 is off; meanwhile, the logic circuit in the photoelectric area distinguishing module 110 can obtain that when the first control signal LED1 is low level, the second control signal LED2 is low level, and the third control signal LED3 is also low level, the electric port connection indicating signal T2 is low level, and the optical port connection indicating signal T3 is also low level, therefore, the first indicating lamp 120 coupled with the electric port connection indicating signal T2 is off, and the third indicating lamp 140 coupled with the optical port connection indicating signal T3 is off.

[0040] For the above four cases, taking the first rate as 100M / 10M, the second rate as 1G, the first diode VD1 as green, the second diode VD2 as green, the third diode VD3 as green, and the fourth diode VD4 as yellow as an example, Table 1 shows the states of different signals and the states of the indicator lights in the above four cases.

[0041] Table 1

[0043]

[0044] T1 in Table 1 is an intermediate signal of the optoelectronic distinguishing module 110. It can also be seen from the above Table 1 that after the control circuit 100 of the Combo indicator light controls the indicator light, it can not only indicate whether the current network port is in the first rate (100M / 10M) state or the second rate (1G) state through color change, but also distinguish whether the connection is an optical port or an electrical port, which meets the actual application of the electrical port and optical port indicator light, and the circuit implementation is simple and easy to control. Figure 1

[0045] Further, the control circuit of the Combo indicator light further includes a sampling module, wherein the sampling module is configured to sample the first control signal LED1 and the second control signal LED2 to control the on-off of the second indicator light 130 according to the level state of the sampled first control signal LED1 and the level state of the sampled second control signal LED2. The sampling module is used to sample the first control signal LED1 and the second control signal LED2. The sampling module can be a logic sampling circuit. In actual application, the first control signal LED1 and the second control signal LED2 are usually obtained through a sampling circuit for the performance of the circuit, instead of directly coupling the pins corresponding to the first control signal LED1 and the second control signal LED2 in the physical layer chip PHY to the indicator light on the Combo side. The implementation of the logic sampling circuit can be any sampling circuit that can collect signal states, and the structure of the logic sampling circuit is not limited in the embodiment.

[0046] Figure 2 A flow chart of a control method of the Combo indicator light is shown. The method is applied to the control circuit of the Combo indicator light. Figure 1 ​The control circuit 100 of the photoelectric multiplexing interface indicator light in the embodiment, specifically, the method comprises the following steps: S201. receiving the first control signal, the second control signal and the third control signal sent by the physical layer chip; S202. generating the electrical port connection indication signal and the optical port connection indication signal for distinguishing the electrical interface or the optical interface connection of the photoelectric multiplexing interface according to the first control signal, the second control signal and the third control signal; S203. controlling the on-off of the first indicator light according to the electrical port connection indication signal; S204. controlling the on-off of the second indicator light according to the level state of the first control signal and the level state of the second control signal; S205. controlling the on-off of the third indicator light according to the optical port connection indication signal.

[0047] In step S201, the first control signal is a signal responding to the first rate state of the electrical interface, the second control signal is a signal responding to the second rate state of the electrical interface, and the third control signal is a signal responding to the connection state of the optical interface and the connection state of the electrical interface. The connection state includes the connection state and the active state. In actual application, after the optical interface or the electrical interface of the photoelectric multiplexing interface is connected, the physical layer chip can receive the connection signal of the photoelectric multiplexing interface through the CPU, and then generate the indicator light control signal based on the received connection signal to control the on-off of the indicator light on the photoelectric multiplexing interface side, so as to indicate the current connection state of the photoelectric multiplexing interface through the on-off of the indicator light. The control signal generated by the physical layer chip in the embodiment includes the first control signal, the second control signal and the third control signal.

[0048] The step S202 is described as follows: from the setting of the first control signal and the second control signal in the above steps, it can be seen that they respond to a state respectively, so that the double-color 1G and 10M / 100M states can be realized by connecting the first control signal and the second control signal to the two sides of the double-color speed indicator light of the electrical interface. However, the third control signal can respond to the electrical port connection and the optical port connection at the same time, and the electrical port connection or the optical port connection of the photoelectric multiplexing interface cannot be distinguished only by the third control signal. Therefore, in the embodiment, the third control signal is combined with the first control signal and the second control signal through the logic circuit to convert into the electrical port connection indication signal and the optical port connection indication signal capable of distinguishing the electrical interface or the optical interface connection of the photoelectric multiplexing interface.

[0049] Further, generating the electrical port connection indication signal and the optical port connection indication signal for distinguishing the electrical interface or the optical interface connection of the photoelectric multiplexing interface according to the first control signal, the second control signal and the third control signal comprises: performing the OR operation on the first control signal and the second control signal to obtain an intermediate signal; performing the AND operation on the intermediate signal and the third control signal to obtain the electrical port connection indication signal; performing the NOT operation on the intermediate signal and then performing the AND operation on the result and the third control signal to obtain the optical port connection indication signal.

[0050] In step S203, the first indicator light is a single-color light arranged at one side of the electrical interface, and the first indicator light comprises a first diode. The control of the on-off of the first indicator light according to the electrical port connection indication signal comprises: if the electrical port connection indication signal is high, the first diode is controlled to be on; and if the electrical port connection indication signal is low, the first diode is controlled to be off. The color of the first diode can be green, and can be adjusted according to actual requirements or changes in industry standards.

[0051] In step S204, the second indicator light is a double-color light arranged at the other side of the electrical interface, and the second indicator light comprises a third diode and a fourth diode with different light colors. The control of the on-off of the second indicator light according to the level state of the first control signal and the level state of the second control signal comprises: if the first control signal is high and the second control signal is low, the third diode is controlled to be on; if the second control signal is high and the first control signal is low, the fourth diode is controlled to be on; and if the first control signal and the second control signal are both low, the third diode and the fourth diode are both controlled to be off. The colors of the third diode and the fourth diode can be green and yellow, and can be adjusted according to actual requirements or changes in industry standards.

[0052] In step S205, the third indicator light is a single-color light arranged at one side of the optical interface, and the third indicator light comprises a second diode. The control of the on-off of the third indicator light according to the optical port connection indication signal comprises: if the optical port connection indication signal is high, the second diode is controlled to be on; and if the optical port connection indication signal is low, the second diode is controlled to be off. The color of the second diode can be green, and can be adjusted according to actual requirements or changes in industry standards.

[0053] It should be noted that although the logical order is shown in the flowchart, in some cases, the steps shown or described can be performed in an order different from that shown here.

[0054] As can be seen from the above method embodiment, the control method of the optical-electrical multiplexing interface indicator light in the embodiment of the present disclosure can not only indicate whether the current network port is in a first rate (100M / 10M) state or a second rate (1G) state through color change after the indicator light is controlled, but also distinguish whether the connection is an optical port or an electrical port, thereby meeting the application of the electrical port and optical port indicator light, and the circuit is simple and easy to control.

[0055] The network device provided by the embodiment of the present disclosure comprises at least a master chip, a physical layer chip, a physical and electrical multiplexing interface, and the control circuit 100 of the physical and electrical multiplexing interface indicator lamp described in the foregoing embodiment. The master chip can be a central processing unit (CPU). After the optical interface or the electrical interface of the physical and electrical multiplexing interface is connected, the physical layer chip receives the connection signal of the physical and electrical multiplexing interface through the master unit, and generates the first control signal, the second control signal, and the third control signal based on the received connection signal. Then, the control circuit of the physical and electrical multiplexing interface indicator lamp receives the first control signal, the second control signal, and the third control signal, and obtains the control signal (the electrical port connection indication signal, the optical port connection indication signal, the first control signal, and the second control signal) for controlling the on-off of the three indicator lamps (the first to third indicator lamps in the foregoing embodiment) on the side of the physical and electrical multiplexing interface through logical conversion, so as to indicate the current connection state of the physical and electrical multiplexing interface through the on-off of the indicator lamps.

[0056] In summary, the control mode of the physical and electrical multiplexing interface indicator lamp in the embodiment of the present disclosure can not only meet the actual application of the electrical port and the optical port, but also has a simple structure and is easy to control.
