Description

Technical Field

[0001] The present invention relates to the field of router signal display, and particularly to a router signal strength display control circuit and a router. Background Art

[0002] With the development of routers, routers are used more and more frequently in various fields. However, the pursuit of router cost has also emerged. As one of the directions for reducing the cost of routers, the signal strength display control circuit in routers has also put forward higher requirements for the hardware design cost of the signal strength display control circuit by users.

[0003] The traditional router signal strength display control circuit directly accesses multiple control signals with different signal strengths, and each control signal is connected to a uniquely corresponding display lamp through wiring for display. Taking a multi-card aggregation router as an example, in order to distinguish 4G and 5G signals, as well as the strong, medium, and weak degrees of different signals, at least 6 wires are required to transmit each control signal to the uniquely corresponding display lamp for display. That is, at least 6 display lamps are also required at this time. This router signal strength display control circuit has great defects. There is a problem that more wiring and display lamps are needed to achieve signal strength display. That is, this router signal strength display control circuit will cause a relatively high cost for router signal strength display due to the need to use more wiring and display lamps to achieve signal strength display.

[0046] The realization, functional features and advantages of the object of the present invention will be further described in conjunction with the embodiments and with reference to the accompanying drawings. Detailed implementation manners

[0047] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts fall within the scope of protection of the present invention.

[0048] It should be noted that if there are directional indications (such as up, down, left, right, front, back...) involved in the embodiments of the present invention, then such directional indications are only used to explain the relative positional relationship, movement conditions, etc. between components in a specific posture (as shown in the attached drawings). If the specific posture changes, then the directional indications will also change accordingly.

[0049] In addition, if there are descriptions such as "first", "second", etc. involved in the embodiments of the present invention, then such descriptions of "first", "second", etc. are only for descriptive purposes and should not be understood as indicating or implying their relative importance or implicitly specifying the quantity of the indicated technical features. Thus, the features defined with "first" and "second" may explicitly or implicitly include at least one such feature. In addition, the technical solutions between various embodiments can be combined with each other, but it must be based on the ability of those of ordinary skill in the art to implement. When the combination of technical solutions results in contradictions or cannot be implemented, it should be considered that such a combination of technical solutions does not exist and is not within the protection scope required by the present invention.

[0050] For the sake of clear and concise description of the following embodiments, first, a brief introduction to a router signal strength display control circuit is given:

[0051] Currently, routers sold and used in the market all need to display signal strength. Taking a multi-card aggregation router as an example, a multi-card aggregation router usually requires multiple modules, that is, modules for multi-channel signal processing and transmission. And for each module, the signal indication usually needs to use the signal provided by the router to indicate the signal strength, corresponding to strong signal, medium signal, and weak signal respectively. For a multi-card aggregation router, the indicator lights in the lamp slot will be particularly numerous. That is, there are both 4G and 5G, and it is also necessary to distinguish between strong, medium, and weak. At least two 3-color lights and 6 control lines are required. For a multi-card aggregation router, more wiring space is occupied. At the same time, having more lights will also make the appearance of the product not look very simple. For example, a certain type of multi-card aggregation router uses 8 5G modules, then 16 (2 * 8) 3-color lights are required to indicate the signal strength, and at the same time, the main board needs to have a wiring space for 48 (corresponding to strong signal, medium signal, and weak signal respectively) lines. To solve such problems, we propose the following router signal strength display control circuit to simplify the complexity by adding some logical controls to the modules and save the wiring space of the PCB board.

[0052] This solution proposes a router signal strength display control circuit, which includes a 4G normal signal display unit. The input end of the 4G normal signal display unit is connected to the first signal strength interface of the router. The output end of the 4G normal signal display unit is connected to the 4G signal display lamp through the first trace. The 4G normal signal display unit is used to receive the 4G signal information of the first signal strength interface and control the 4G signal display lamp to display the signal strength based on the 4G signal information; a 5G normal signal display unit. The input end of the 5G normal signal display unit is connected to the second signal strength interface of the router. The output end of the 5G normal signal display unit is connected to the 5G signal display lamp through the second trace. The 5G normal signal display unit is used to receive the 5G signal information of the second signal strength interface and control the 5G signal display lamp to display the signal strength based on the 5G signal information; an abnormal signal display unit. The input end of the abnormal signal display unit is connected to the third signal strength interface of the router. The output end of the abnormal signal display unit is connected to the abnormal signal display lamp through the third trace. The abnormal signal display unit is used to receive the abnormal signal information of the third signal strength interface and control the abnormal signal display lamp to display the signal strength based on the abnormal signal information. The signal strength is displayed by connecting the output end of the 4G normal signal display unit to the 4G signal display lamp through the first trace, connecting the output end of the 5G normal signal display unit to the 5G signal display lamp through the second trace, and connecting the output end of the abnormal signal display unit to the abnormal signal display lamp through the third trace. That is, only three traces and three display lamps are needed at this time to complete the router signal strength display. Thus, it avoids the phenomenon in the prior art that more traces and display lamps are needed to achieve signal strength display. This router signal strength display control circuit not only provides a new way of router signal strength display control, but also only needs three traces and three display lamps to complete the router signal strength display, thereby reducing the cost of router signal strength display.

[0053] The present invention proposes a router signal strength display control circuit.

[0054] In an embodiment of the present invention, as Figure 1 shown, Figure 1 is a schematic structural framework diagram of the router signal strength display control circuit. The router signal strength display control circuit 200 includes:

[0055] 4G normal signal display unit 10, the input end of the 4G normal signal display unit 10 is connected to the first signal strength interface 110 of the router 100, and the output end of the 4G normal signal display unit 10 is connected to the 4G signal display lamp 30 through the first wire 20. The 4G normal signal display unit 10 is configured to receive the 4G signal information of the first signal strength interface 110 and control the 4G signal display lamp 30 to perform signal strength display based on the 4G signal information;

[0056] 5G normal signal display unit 40, the input end of the 5G normal signal display unit 40 is connected to the second signal strength interface 120 of the router 100, and the output end of the 5G normal signal display unit 40 is connected to the 5G signal display lamp 60 through the second wire 50. The 5G normal signal display unit 40 is configured to receive the 5G signal information of the second signal strength interface 120 and control the 5G signal display lamp 60 to perform signal strength display based on the 5G signal information;

[0057] Abnormal signal display unit 70, the input end of the abnormal signal display unit 70 is connected to the third signal strength interface 130 of the router 100, and the output end of the abnormal signal display unit 70 is connected to the abnormal signal display lamp 90 through the third wire 80. The abnormal signal display unit 70 is configured to receive the abnormal signal information of the third signal strength interface 130 and control the abnormal signal display lamp 90 to perform signal strength display based on the abnormal signal information.

[0058] In this embodiment, the 4G normal signal controls the 4G signal display lamp 30 to perform signal strength display through the 4G normal signal display unit 10 and a first wire 20; the 5G normal signal controls the 5G signal display lamp 60 to perform signal strength display through the 5G normal signal display unit 40 and a second wire 50; the abnormal signal controls the abnormal signal display lamp 90 to perform signal strength display through the abnormal signal display unit 70 and a third wire 80. Among them, the 4G normal signal includes 4G strong signal and 4G medium signal, the 5G normal signal includes 5G strong signal and 5G medium signal, and the abnormal signal includes 4G weak signal and 5G weak signal. The strong signal refers to the signal with higher signal strength, the medium signal refers to the signal with general signal strength, and the weak signal refers to the signal with poor signal strength. In terms of signal bars, the strong signal is the full bar and nearly full bar signal, the medium signal is the signal with fluctuating middle bars, and the weak signal is the signal with one bar, half bar or no signal. Therefore, at this time, the strong, medium, and weak signals of 4G and 5G signals can be displayed based on three display lamps and three wires, reducing the use of display lamps and wires, and thus reducing the cost of router signal strength display.

[0059] In one embodiment, the router signal strength display circuit reduces the signal indicator control by adding some logic controls (internal logic controls of the 4G normal signal display unit 10, the 5G normal signal display unit 40, and the abnormal signal display unit 70), and reduces the number of indicator lights, so as to achieve the purpose of reducing the number of traces on the PCB (Printed Circuit Board). It should be noted that here, it can also be the strong, medium, and weak displays of more types of signals, such as 4G, 5G, Bluetooth signals, etc., without configuring three display lights and corresponding traces for each signal, so as to reduce the cost of router signal strength display.

[0060] In this embodiment, a router signal strength display control circuit is provided. The circuit includes a 4G normal signal display unit. The input end of the 4G normal signal display unit is connected to the first signal strength interface of the router. The output end of the 4G normal signal display unit is connected to the 4G signal display light through the first trace. The 4G normal signal display unit is used to receive the 4G signal information of the first signal strength interface and control the 4G signal display light to display the signal strength based on the 4G signal information; a 5G normal signal display unit. The input end of the 5G normal signal display unit is connected to the second signal strength interface of the router. The output end of the 5G normal signal display unit is connected to the 5G signal display light through the second trace. The 5G normal signal display unit is used to receive the 5G signal information of the second signal strength interface and control the 5G signal display light to display the signal strength based on the 5G signal information; an abnormal signal display unit. The input end of the abnormal signal display unit is connected to the third signal strength interface of the router. The output end of the abnormal signal display unit is connected to the abnormal signal display light through the third trace. The abnormal signal display unit is used to receive the abnormal signal information of the third signal strength interface and control the abnormal signal display light to display the signal strength based on the abnormal signal information. The signal strength is displayed by connecting the output end of the 4G normal signal display unit to the 4G signal display light through the first trace, connecting the output end of the 5G normal signal display unit to the 5G signal display light through the second trace, and connecting the output end of the abnormal signal display unit to the abnormal signal display light through the third trace. That is, only three traces and three display lights are required to complete the router signal strength display at this time. Thus, it avoids the phenomenon in the prior art that a large number of traces and display lights are required to achieve signal strength display. This router signal strength display control circuit not only provides a new way of router signal strength display control, but also only requires three traces and three display lights to complete the router signal strength display, thereby reducing the cost of router signal strength display.

[0061] Further, in another embodiment of the router signal strength display control circuit of the present application, refer to Figure 2 , Figure 2 which is a circuit schematic diagram of the 4G normal signal display unit in the router signal strength display control circuit of the present invention. The first signal strength interface 110 includes a 4G strong signal interface 111 and a 4G medium signal interface 112. The 4G normal signal display unit 10 includes:

[0062] A first power supply VCC1;

[0063] A first capacitor C1, the first end of the first capacitor C1 is connected to the first power supply VCC1, and the second end of the first capacitor C1 is grounded;

[0064] A first logic OR chip U1, the first input terminal A1 of the first logic OR chip is connected to the 4G strong signal interface 111, the second input terminal B1 of the first logic OR chip is connected to the 4G medium signal interface 112, the power supply terminal of the first logic OR chip U1 is connected to the first power supply VCC1, and the output terminal Y1 of the first logic OR chip U1 is connected to the 4G signal display lamp 30 through the first trace 20.

[0065] Specifically, when the 4G strong signal interface 111 outputs a high level or the 4G medium signal interface 112 outputs a high level, the output terminal Y1 of the first logic OR chip outputs a high level to control the 4G signal display lamp 30 to light up;

[0066] When the 4G strong signal interface 111 outputs a low level and the 4G medium signal interface 112 outputs a low level, the output terminal Y1 of the first logic OR chip outputs a low level to control the 4G signal display lamp 30 to go out.

[0067] In one embodiment, the 4G normal signal display unit 10 includes a first power supply VCC1, a first capacitor C1 and a first logic OR chip U1. The first power supply VCC1 and the first capacitor C1 are used to supply power to the first logic OR chip U1 to enable the first logic OR chip U1 to work normally. The first logic OR chip U1 can be a common OR logic chip, such as SN74LS32, SN7432, CD4071, etc. At this time, only two interfaces are needed to input the 4G strong signal 4GS of the 4G strong signal interface 111 and the 4G medium signal 4GN of the 4G medium signal interface 112 respectively. Then, as long as one signal is at a high level, it can control the 4G signal display lamp 30 to light up. Only when both signals are at a low level will it control the 4G signal display lamp 30 to go out, so as to display the signal strength of the 4G signal at low cost. Refer to Table 1, and Table 1 is the control logic of the first logic OR chip U1 inside the 4G normal signal display unit 10.

[0068]

[0069] Table 1

[0070] As can be seen from Table 1, the entire 4G normal signal display unit 10 can achieve that when the 4G strong signal interface 111 outputs a high level or the 4G medium signal interface 112 outputs a high level, the output terminal Y1 of the first logic OR chip outputs a high level to control the 4G signal display lamp 30 to light up; when the 4G strong signal interface 111 outputs a low level and the 4G medium signal interface 112 outputs a low level, the output terminal Y1 of the first logic OR chip outputs a low level to control the 4G signal display lamp 30 to turn off. Among them, the 4G strong signal interface 111 outputting a high level indicates that it is a 4G strong signal at this time, and the 4G strong signal interface 111 outputting a low level indicates that it is a 4G weak signal at this time, and its detection method will not be elaborated here. Furthermore, it can be realized that the strong and medium detection of the 4G signal is achieved by one display lamp and a wire corresponding to this lamp, saving at least one display lamp and a wire corresponding to this lamp, thereby reducing the cost of the router signal strength display.

[0071] Furthermore, in another embodiment of the router signal strength display control circuit of the present application, referring to Figure 3 , Figure 3 is a circuit schematic diagram of the 5G normal signal display unit in the router signal strength display control circuit of the present invention. The second signal strength interface 120 includes a 5G strong signal interface 121 and a 5G medium signal interface 122. The 5G normal signal display unit 40 includes:

[0072] The second power supply VCC2;

[0073] The second capacitor C2, the first end of the second capacitor C2 is connected to the second power supply VCC2, and the second end of the second capacitor C2 is grounded;

[0074] The second logic OR chip U2, the first input terminal A2 of the second logic OR chip is connected to the 5G strong signal interface 121, the second input terminal B2 of the second logic OR chip is connected to the 5G medium signal interface 122, the power supply terminal of the second logic OR chip U2 is connected to the second power supply VCC2, and the output terminal Y2 of the second logic OR chip is connected to the 5G signal display lamp 60 through the second wire 50.

[0075] Specifically, when the 5G strong signal interface 121 outputs a high level or the 5G medium signal interface 122 outputs a high level, the output terminal Y2 of the second logic OR chip outputs a high level to control the 5G signal display lamp 60 to light up;

[0076] When the output of the 5G strong signal interface 121 is at a low level and the output of the 5G medium signal interface 122 is at a low level, the output terminal Y2 of the second logic OR chip outputs a low level to control the 5G signal display lamp 60 to turn off.

[0077] In this embodiment, the 5G normal signal display unit 40 includes a second power supply VCC2, a second capacitor C2, and a second logic OR chip U2. The second power supply VCC2 and the second capacitor C2 are used to supply power to the second logic OR chip U2 to enable the second logic OR chip U2 to work properly. The second logic OR chip U2 can be a common OR logic chip, such as SN74LS32, SN7432, CD4071, etc. At this time, only two interfaces are needed to respectively input the 5G strong signal 5GS of the 5G strong signal interface 121 and the 5G medium signal 5GN of the 5G medium signal interface 122. Then, as long as one signal is at a high level, it can control the 5G signal display lamp 60 to light up. Only when both signals are at a low level will it control the 5G signal display lamp 60 to turn off, so as to display the signal strength of the 5G signal at low cost. Refer to Table 2, and Table 2 is the control logic of the second logic OR chip U2 inside the 5G normal signal display unit 40.

[0080] Table 2

[0081] As can be seen from Table 2, the entire 5G normal signal display unit 60 can achieve that when the output of the 5G strong signal interface 121 is at a high level or the output of the 5G medium signal interface 122 is at a high level, the output terminal Y2 of the second logic OR chip outputs a high level to control the 5G signal display lamp 60 to light up; when the output of the 5G strong signal interface 121 is at a low level and the output of the 5G medium signal interface 122 is at a low level, the output terminal Y2 of the second logic OR chip outputs a low level to control the 5G signal display lamp 60 to turn off. Among them, the 5G strong signal interface 121 outputting a high level indicates that it is a 5G strong signal at this time, and the 5G strong signal interface 121 outputting a low level indicates that it is a 5G weak signal at this time. The detection method is not elaborated here. Furthermore, it can be realized that the strong and medium detection of the 5G signal is achieved with one display lamp and a wire corresponding to this lamp, saving at least one display lamp and a wire corresponding to this lamp, thereby reducing the cost of the router signal strength display.

[0082] Furthermore, in another embodiment of the router signal strength display control circuit of the present application, refer to Figure 4 , Figure 4This is a circuit schematic diagram of the abnormal signal display unit in the router signal strength display control circuit of the present invention. The third signal strength interface 130 includes a 5G weak signal interface 131 and a 4G weak signal interface 132. The abnormal signal display unit 70 includes:

[0083] A third power supply VCC3;

[0084] A third capacitor C3. The first end of the third capacitor C3 is connected to the third power supply VCC3, and the second end of the third capacitor C3 is grounded;

[0085] A logic AND chip U3. The first input terminal A3 of the logic AND chip is connected to the 4G weak signal interface 131, the second input terminal B3 of the logic AND chip is connected to the 5G weak signal interface 132, the power supply terminal of the logic AND chip U3 is connected to the third power supply VCC3, and the output terminal Y3 of the logic AND chip is connected to the abnormal signal display lamp 90 through the third trace.

[0086] Specifically, when the 5G weak signal interface 131 outputs a high level and the 4G weak signal interface 132 outputs a high level, the output terminal Y3 of the logic AND chip outputs a high level to control the abnormal signal display lamp 90 to light up;

[0087] When the 5G weak signal interface 131 outputs a low level or the 4G weak signal interface 132 outputs a low level, the output terminal Y3 of the logic AND chip outputs a low level to control the abnormal signal display lamp 90 to go out.

[0088] In this embodiment, the abnormal signal display unit 70 includes a third power supply VCC3, a third capacitor C3, and a logic AND chip U3. The third power supply VCC3 and the third capacitor C3 are used to supply power to the logic AND chip U3 to enable the normal operation of the logic AND chip U3. The logic AND chip U3 can be a common AND logic chip, such as SN74LS08, SN7408, CD4081, etc. At this time, only two interfaces are needed to respectively input the 5G weak signal 5GW of the 5G weak signal interface 131 and the 4G weak signal 4GW of the 4G weak signal interface 132. Furthermore, as long as one signal is at a low level, it can control the abnormal signal display lamp 90 to go out, and only when both signals are at a high level will it control the abnormal signal display lamp 90 to light up, so as to display the signal strength of the abnormal signal (5G weak signal 5GW or 4G weak signal 4GW) at low cost. Refer to Table 3, and Table 3 is the control logic of the internal logic AND chip U3 of the abnormal signal display unit 70.

[0089]

[0090] Table 3

[0091] As can be seen from Table 3, the entire abnormal signal display unit 70 can realize that when the 5G weak signal interface 131 outputs a high level and the 4G weak signal interface 132 outputs a high level, the output terminal Y3 of the logic and chip outputs a high level, and the abnormal signal display light 90 is controlled to light up; when the 5G weak signal interface 131 outputs a low level or the 4G weak signal interface 132 outputs a low level, the output terminal Y3 of the logic and chip outputs a low level, and the abnormal signal display light 90 is controlled to go out. Among them, the 5G weak signal interface 131 outputs a high level to indicate that it is a 5G weak signal at this time, and the 5G weak signal interface 131 outputs a low level to indicate that it is a 4G strong signal or a 4G medium signal at this time, and its detection method is not described in detail here. In addition, the detection of abnormal signals can be realized by using a display light and a wiring corresponding to the light, which saves at least a display light and a wiring corresponding to the light, thereby reducing the cost of displaying the signal strength of the router.

[0092] In one embodiment, the 4G signal display light 30 can be defined as a blue light to indicate that the 5G signal is normal and the signal strength is strong or moderate. The 5G signal display light 60 can be defined as a green light to indicate that the 4G signal is normal and the signal strength is strong or moderate. The abnormal signal display light 90 can be defined as a red light to indicate that the 5G & 4G signals are weak and the signal strength is in weak coverage. The power supply used can be the same power supply, or can be called in time-sharing with the logic chip, etc.

[0093] In one embodiment, to achieve the display of signals with different intensities, a control logic can be set in the router signal strength display control circuit. Through the controller connected to the first signal strength interface 110, the second signal strength interface 120, and the third signal strength interface 130 for logical control, when the abnormal signal display light 90 is lit, it is determined at this time that both 5G signals are weak signals; when the 4G signal display light 30 is lit, the information of the first signal strength interface 110 is obtained. If there is a 4G strong signal 4GS at this time, a first control signal is generated through the controller, and based on the first control signal, the 5G signal display light 60 is indirectly lit. Conversely, if there is a 4G medium signal 4GN at this time, a second control signal is generated through the controller, and based on the second control signal, the abnormal signal display light 90 is indirectly lit. The first control signal refers to an indirectly high-level signal for controlling the lighting of the 5G signal display light 60, and the second control signal refers to an indirectly high-level signal for controlling the lighting of the abnormal signal display light 90. At this time, the user can clearly know the specific signal intensity. If only the 4G signal display light 30 is lit alone, it can be determined that the signal is a 4G medium or strong signal at this time; when the 5G signal display light 60 is lit, the information of the second signal strength interface 120 is obtained. If there is a 5G strong signal 5GS at this time, a third control signal is generated through the controller, and based on the third control signal, the 4G signal display light 30 is indirectly lit. Conversely, if there is a 5G medium signal 5GN at this time, a fourth control signal is generated through the controller, and based on the fourth control signal, the abnormal signal display light 90 is indirectly lit. The third control signal refers to an indirectly high-level signal for controlling the lighting of the 4G signal display light 30, and the fourth control signal refers to an indirectly high-level signal for controlling the lighting of the abnormal signal display light 90. At this time, the user can clearly know the specific signal intensity. If only the 4G signal display light 30 is lit alone, it can be determined that the signal is a 4G medium or strong signal at this time. It should be noted that at this time, an AND operation output can be performed with the 4G strong signal 4GS and the 5G strong signal 5GS in Table 1, and an AND operation output can be performed with the 4G medium signal 4GN and the 5G medium signal 5GN in Table 1, which is not limited herein.

[0094] Further, in another embodiment of the router signal strength display control circuit of the present application, referring to Figure 5 , Figure 5 is another structural framework diagram of the router signal strength display control circuit of the present invention. The router signal strength display control circuit 200 further includes:

[0095] Device status detection unit A0, the input end of the device status detection unit A0 is connected to the status input interface 140 of the router 100, and the output end of the device status detection unit A0 is connected to the ground terminals of the 5G signal display lamp 60, the 4G signal display lamp 30, and the abnormal signal display lamp 90 through the fourth wire B0. The device status detection unit A0 is configured to receive the device status information of the status input interface 140 and control the 5G signal display lamp 60, the 4G signal display lamp 30, and the abnormal signal display lamp 90 to display the device status based on the device status information.

[0096] Specifically, referring to Figure 6 , Figure 6 is a circuit schematic diagram of the device status detection unit in the router signal strength display control circuit of the present invention. The status input interface 140 includes a card status interface 141, a network status interface 142, and a power status interface 143. The device status detection unit A0 includes:

[0097] Fourth power supply VCC4;

[0098] Fourth capacitor C4, the first end of the fourth capacitor C4 is connected to the fourth power supply VCC4, and the second end of the fourth capacitor C4 is grounded;

[0099] Third logic OR chip U4, the first input terminal A4 of the third logic OR chip is connected to the card status interface 141, the second input terminal B4 of the third logic OR chip is connected to the network status interface 142, the third input terminal C4 of the third logic OR chip is connected to the power status interface 143, the power supply terminal of the third logic OR chip U4 is connected to the fourth power supply VCC4, and the output terminal Y4 of the third logic OR chip is connected to the ground terminals of the 5G signal display lamp 60, the 4G signal display lamp 30, and the abnormal signal display lamp 90 through the fourth wire B0.

[0100] In this embodiment, the router signal strength display control circuit 200 further includes a device status detection unit A0. The device status detection unit A0 includes a fourth power supply VCC1, a fourth capacitor C4, and a third logic OR chip U4. The fourth power supply VCC4 and the fourth capacitor C4 are used to supply power to the third logic OR chip U4 to enable the third logic OR chip U4 to operate normally. The third logic OR chip U4 can be a common OR logic chip, such as SN74LS32, SN7432, CD4071, etc. At this time, only at least three interfaces need to be used, which are respectively connected to the card status KT of the card status interface 141, the network status WT of the network status interface 142, and the power status DT of the power status interface 143. Then, as long as one signal is high level, the output can be controlled to be high level, thereby controlling the 4G signal display lamp 30, the 5G signal display lamp 60, and the abnormal signal display lamp 90 to go out. Only when all three signals are low level will the 4G signal display lamp 30, the 5G signal display lamp 60, and the abnormal signal display lamp 90 be normally controlled, so as to display the router status at low cost. Refer to Table 4. Table 4 is the control logic of the third logic OR chip U4 inside the device status detection unit A0.

[0101]

[0102] Table 4

[0103] As can be seen from Table 4, the entire device status detection unit A0 can achieve that when the card status interface 141 outputs a high level (when inserting a SIM (Subscriber Identity Module) card), the network status interface 142 outputs a high level, or the power status interface 143 outputs a high level (when accessing power), the output terminal Y4 of the third logic OR chip outputs a high level, controlling the 4G signal indicator light 30, the 5G signal indicator light 60, and the abnormal signal indicator light 90 to all turn off; when the card status interface 141, the network status interface 142, and the power status interface 143 all output low levels, the output terminal Y4 of the third logic OR chip outputs a low level, and the 4G signal indicator light 30, the 5G signal indicator light 60, and the abnormal signal indicator light 90 are normally controlled. Among them, the network status interface 142 outputting a high level indicates that the network status interface 142 discovers that it is in an unconnected state at this time, and the network status interface 142 outputting a low level indicates that the network status interface 142 discovers that it is in a connected state at this time. The detection methods for network status, power status, and card status are not elaborated here. Furthermore, the status detection of the entire router can be achieved, ensuring that users can clearly know the real-time router status. It should be noted that the status monitoring at this time can also be: the router device continuously operates under high temperature; the SIM card is not recognized, the PIN code is not entered, or the PIN code verification fails; the SIM card is recognized, but the network connection fails; the power supply is not connected, etc. At this time, the control method can be to connect a selector to the ground terminals of the 4G signal indicator light 30, the 5G signal indicator light 60, and the abnormal signal indicator light 90. Under normal circumstances, the selector outputs a low level for control, and the first terminal of the selector is grounded. At this time, the ground terminals of the 4G signal indicator light 30, the 5G signal indicator light 60, and the abnormal signal indicator light 90 are all grounded through the first terminal of the selector. Therefore, the 4G signal indicator light 30, the 5G signal indicator light 60, and the abnormal signal indicator light 90 are normally controlled, that is, the control in Tables 1 - 3 above is executed; conversely, when there are the above abnormal status situations, the selector outputs a high level for control, and the second terminal of the selector is connected to a high level. At this time, the ground terminals of the 4G signal indicator light 30, the 5G signal indicator light 60, and the abnormal signal indicator light 90 are all connected to a high level through the second terminal of the selector. Therefore, no matter how the other end of the indicator light is controlled, the indicator light is turned off at this time to achieve router status detection.
