Description

Technical Field

[0002] With the development of routers, they are used more and more frequently in various fields, but this is accompanied by the pursuit of router cost. The signal strength display control circuit in the router is one of the directions for reducing the cost of the router, which also makes users put forward higher requirements on the hardware design cost of the signal strength display control circuit.

[0003] The traditional router signal strength display control circuit directly accesses multiple control signals of different signal strengths, and connects each control signal to a unique corresponding display light 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 strength, medium and weak levels of different signals, at least 6 wirings are required to transmit each control signal to a unique corresponding display light for display, that is, at this time, at least 6 display lights are also required. This router signal strength display control circuit has a big defect, and there is a problem that more wirings and display lights are needed to realize signal strength display. That is, this router signal strength display control circuit will require more wirings and display lights to realize signal strength display, resulting in a high cost for router signal strength display.

If the specific posture changes, the directional indication will also change accordingly.

[0049] In addition, if there are descriptions involving "first", "second", etc. in the embodiments of the present invention, the descriptions of "first", "second", etc. are only used for descriptive purposes and cannot be understood as indicating or suggesting their relative importance or implicitly indicating the number of the indicated technical features.

When the combination of technical solutions is contradictory or cannot be implemented, it should be deemed that such a combination of technical solutions does not exist and is not within the scope of protection required by the present invention.

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

[0051] At present, all routers sold and used in the market need to display signal strength. Taking multi-card aggregation routers as an example, multi-card aggregation routers usually require multi-channel modules, that is, modules for multi-channel signal processing and transmission, and the signal indication for each module 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 multi-card aggregation routers, the indicator lights of the light slot will be particularly large, that is, there are 4G and 5G, and it is necessary to distinguish between strong, medium and weak. At least two 3-color lights plus 6 control lines are required, which takes up more wiring space for multi-card aggregation routers. At the same time, if there are too many lights, the appearance of the product will 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 for signal strength indication, and the motherboard needs to have 48 (corresponding to strong signal, medium signal, and weak signal) wires for wiring space. In order to solve this kind of problem, we propose the following router signal strength display control circuit to simplify the complexity by adding some logic control to the module and save the wiring space of the PCB board.

[0052] The present invention 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 light through a first wiring, 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, and the 5G normal signal display light is used to display the signal strength. The output end of the display unit is connected to the 5G signal display light through the second wiring, and 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; the 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 wiring, and 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 wiring, the output end of the 5G normal signal display unit to the 5G signal display light through the second wiring, and the output end of the abnormal signal display unit to the abnormal signal display light through the third wiring, that is, only three wirings and three display lights are needed to complete the router signal strength display. This avoids the phenomenon in the prior art that a large number of wirings and display lights are needed to realize signal strength display. This router signal strength display control circuit not only provides a new router signal strength display control method, but also only requires three wirings and three display lights to complete the router signal strength display, thereby reducing the cost of router signal strength display.

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

[0054] In one embodiment of the present invention, Figure 1 As shown, Figure 1 Schematic diagram of the structure framework of the router signal strength display control circuit. The router signal strength display control circuit 200 includes:

[0055] A 4G normal signal display unit 10, wherein 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 light 30 through the first wiring 20, and the 4G normal signal display unit 10 is used to receive the 4G signal information of the first signal strength interface 110, and control the 4G signal display light 30 to display the signal strength based on the 4G signal information;

[0056] A 5G normal signal display unit 40, wherein 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 light 60 through the second wiring 50, and the 5G normal signal display unit 40 is used to receive the 5G signal information of the second signal strength interface 120, and control the 5G signal display light 60 to display the signal strength based on the 5G signal information;

[0057] An 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, the output end of the abnormal signal display unit 70 is connected to the abnormal signal display light 90 through the third wiring 80, and the abnormal signal display unit 70 is used to receive abnormal signal information of the third signal strength interface 130, and control the abnormal signal display light 90 to display the signal strength based on the abnormal signal information.

[0058] In this embodiment, the signal strength of the 4G normal signal is displayed by controlling the 4G signal display light 30 through the 4G normal signal display unit 10 and a first wiring 20; the signal strength of the 5G normal signal is displayed by the 5G normal signal display unit 40, a second wiring 50 and a 5G signal display light 60; the signal strength of the abnormal signal is displayed by controlling the abnormal signal display light 90 through the abnormal signal display unit 70 and a third wiring 80, wherein the 4G normal signal includes a 4G strong signal and a 4G medium signal, the 5G normal signal includes a 5G strong signal and a 5G medium signal, and the abnormal signal includes a 4G weak signal and a 5G weak signal. A strong signal refers to a signal with a relatively high signal strength, a medium signal refers to a signal with a general signal strength, and a weak signal refers to a signal with a relatively poor signal strength. The signal grid number is used to evaluate the strong signal, which is a full grid or a nearly full grid signal, a medium signal is a signal with a fluctuating number of grids, and a weak signal is one grid, half a grid 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 lights and three wirings, thereby reducing the use of display lights and wiring, and thus reducing the cost of router signal strength display.

[0059] In one embodiment, the router signal strength display circuit reduces the signal indicator light control by adding some logic control (internal logic control of the 4G normal signal display unit 10, the 5G normal signal display unit 40 and the abnormal signal display unit 70), thereby reducing the number of indicator lights and thus reducing the number of PCB (Printed Circuit Board) wiring. It is worth noting that more types of signals can also be displayed as strong, medium and weak, such as 4G, 5G, Bluetooth signals, etc., without the need to configure three display lights and corresponding wiring for each signal, so as to reduce the cost of the router signal strength display.

[0060] In the present embodiment, a router signal strength display control circuit is provided, 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 light through a first wiring, 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, and the 5G normal signal The output end of the signal display unit is connected to the 5G signal display light through the second wiring, and 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; the 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 wiring, and 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 wiring, the output end of the 5G normal signal display unit to the 5G signal display light through the second wiring, and the output end of the abnormal signal display unit to the abnormal signal display light through the third wiring, that is, only three wirings and three display lights are needed to complete the router signal strength display. This avoids the phenomenon in the prior art that a large number of wirings and display lights are needed to realize signal strength display. This router signal strength display control circuit not only provides a new router signal strength display control method, but also only requires three wirings 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, referring to Figure 2 , Figure 2 This is a circuit diagram of a 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, wherein a first end of the first capacitor C1 is connected to the first power supply VCC1, and a second end of the first capacitor C1 is grounded;

[0064] The 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 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 is connected to the 4G signal display light 30 through the first wiring 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 light 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 light 30 to turn off.

[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 power the first logic or chip U1 so that the first logic or chip U1 works normally. The first logic or chip U1 can be a commonly used or logic chip, such as SN74LS32, SN7432, CD4071, etc. At this time, only two interfaces need to be used 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, and then only one signal is high level to control the 4G signal display light 30 to light up, and only when both signals are low level will the 4G signal display light 30 be controlled to go out, so that the signal strength of the 4G signal can be displayed at a low cost. Please refer to Table 1, which 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 light 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 light 30 to go out. Among them, the 4G strong signal interface 111 outputs a high level to indicate that it is a 4G strong signal at this time, and the 4G strong signal interface 111 outputs a low level to indicate that it is a 4G weak signal at this time, and its detection method is not described in detail here. In addition, it can be achieved that a display light and a corresponding wiring of the light can realize the strong and medium detection of the 4G signal, which saves at least a display light and a common wiring corresponding to the light, thereby reducing the cost of displaying the signal strength of the router.

[0071] Further, in another embodiment of the router signal strength display control circuit of the present application, referring to Figure 3 , Figure 3 This is a circuit diagram of a 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] A second power supply VCC2;

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

Among them, the 5G strong signal interface 121 outputs a high level to indicate that it is a 5G strong signal at this time, and the 5G strong signal interface 121 outputs a low level to indicate that it is a 5G weak signal at this time, and its detection method is not detailed here. In addition, it can be achieved that a display light and a corresponding wiring of the light can realize the strong and medium detection of 5G signals, which saves at least a display light and a common wiring corresponding to the light, thereby reducing the cost of displaying the signal strength of the router.

[0082] Further, in another embodiment of the router signal strength display control circuit of the present application, referring to Figure 4 , Figure 4The circuit diagram of the abnormal signal display unit in the router signal strength display control circuit of the present invention is as follows. 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, a first end of the third capacitor C3 is connected to the third power supply VCC3, and a second end of the third capacitor C3 is grounded;

[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, and controls the abnormal signal display light 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 light 90 to turn off.

[0088] In this embodiment, the abnormal signal display unit 70 includes a third power supply VCC3, a third capacitor C3 and a logic chip U3. The third power supply VCC3 and the third capacitor C3 are used to power the logic chip U3 so that the logic chip U3 can work normally. The logic chip U3 can be a commonly used logic chip, such as SN74LS08, SN7408, CD4081, etc. At this time, only two interfaces need to be used to 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, respectively. Then, only one signal is at a low level to control the abnormal signal display light 90 to go out, and only when both signals are at a high level will the abnormal signal display light 90 be controlled to light up, so that the signal strength of the abnormal signal (5G weak signal 5GW or 4G weak signal 4GW) can be displayed at a low cost. Refer to Table 3, which 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, in order to realize the display of signals with different strengths, a control logic can be set in the router signal strength display control circuit, and a controller connected to the first signal strength interface 110, the second signal strength interface 120 and the third signal strength interface 130 is set to perform logic control. When the abnormal signal display light 90 is on, it is determined that both 5G and 5G are weak signals; when the 4G signal display light 30 is on, 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 by the controller, and the 5G signal display light 60 is controlled to light up indirectly based on the first control signal. On the contrary, if there is a 4G medium signal 4GN at this time, a second control signal is generated by the controller, and the abnormal signal display light 90 is controlled to light up indirectly based on the second control signal. The first control signal refers to an indirect high-level signal for controlling the 5G signal display light 60 to light up, and the second control signal refers to a high-level signal for controlling the abnormal signal display light 9 0 lights up, the user can now clearly know why the signal strength is. If only the 4G signal display light 30 lights up alone, it can be determined that it is a 4G medium or strong signal at this time. When the 5G signal display light 60 lights up, 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 by the controller, and the 4G signal display light 30 is indirectly controlled to light up based on the third control signal. Conversely, if there is a 5G medium signal 5GN at this time, a fourth control signal is generated by the controller, and the abnormal signal display light 90 is indirectly controlled to light up based on the fourth control signal. The third control signal refers to the indirect high-level signal for controlling the 4G signal display light 30 to light up, and the fourth control signal refers to the indirect high-level signal for controlling the abnormal signal display light 90 to light up. At this time, the user can clearly know why the signal strength is. If only the 4G signal display light 30 lights up alone, it can be determined that it is a 4G medium or strong signal at this time. It is worth noting that at this time, the 4G strong signal 4GS and the 5G strong signal 5GS can be ANDed in Table 1 and the 4G medium signal 4GN and the 5G medium signal 5GN can be ANDed in Table 1, which is not limited here.

[0094] Further, in another embodiment of the router signal strength display control circuit of the present application, referring to Figure 5 , Figure 5 2 is another structural framework diagram of the router signal strength display control circuit of the present invention, wherein the router signal strength display control circuit 200 further includes:

[0095] A device status detection unit A0, wherein 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 end of the 5G signal display light 60, the ground end of the 4G signal display light 30 and the ground end of the abnormal signal display light 90 through the fourth wiring B0. The device status detection unit A0 is used to receive the device status information of the status input interface 140, and control the 5G signal display light 60, the 4G signal display light 30 and the abnormal signal display light 90 to display the device status based on the device status information.

[0096] Specifically, refer to Figure 6 , Figure 6 Schematic diagram of a circuit of a device status detection unit in a 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] A fourth power supply VCC4;

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

[0099] The 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 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 terminal of the 5G signal display light 60, the ground terminal of the 4G signal display light 30 and the ground terminal of the abnormal signal display light 90 through the fourth routing B0.

[0100] In this embodiment, the router signal strength display control circuit 200 also includes a device status detection unit A0, which 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 power the third logic or chip U4 so that the third logic or chip U4 works normally. The third logic or chip U4 can be a commonly used or logic chip, such as SN74LS32, SN7432, CD4071, etc. At this time, only at least three interfaces need to be used, respectively accessing 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, and then only one signal is at a high level to control the output to be a high level, and then control the 4G signal display light 30, the 5G signal display light 60 and the abnormal signal display light 90 to go out. Only when the three signals are all at a low level will the 4G signal display light 30, the 5G signal display light 60 and the abnormal signal display light 90 be controlled normally, so that the router status can be displayed at a low cost. Please refer to Table 4, which shows 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 state detection unit A0 can realize that when the card state interface 141 outputs a high level (for inserting a SIM (Subscriber Identity Module) card), the network state interface 142 outputs a high level, or the power state interface 143 outputs a high level (connecting to the power supply), the output terminal Y4 of the third logic or chip outputs a high level, and the 4G signal display light 30, the 5G signal display light 60, and the abnormal signal display light 90 are all turned off; when the card state interface 141, the network state interface 142, and the power state interface 143 all output a low level, the output terminal Y4 of the third logic or chip outputs a low level, and the 4G signal display light 30, the 5G signal display light 60, and the abnormal signal display light 90 are controlled normally. Among them, the network state interface 142 outputs a high level to indicate that the network state interface 142 finds that it is not connected to the network at this time, and the network state interface 142 outputs a low level to indicate that the network state interface 142 finds that it is connected to the network at this time. The detection methods of the network state, the power state, and the card state are not described in detail here. Then the status of the entire router can be detected, ensuring that users can clearly know the real-time status of the router. It is worth noting that the status monitoring can also be: the router device is continuously at 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 end of the 4G signal display light 30, the 5G signal display light 60 and the abnormal signal display light 90. Under normal circumstances, the selector outputs a low level for control, and the first end of the selector is grounded. At this time, the ground ends of the 4G signal display light 30, the 5G signal display light 60 and the abnormal signal display light 90 are all grounded through the first end of the selector, so the 4G signal display light 30, the 5G signal display light 60 and the abnormal signal display light 90 are normally controlled, that is, the control of the above Tables 1 to 3 is executed; on the contrary, when the above state is abnormal, the selector outputs a high level for control, and the second end of the selector is connected to a high level. At this time, the ground ends of the 4G signal display light 30, the 5G signal display light 60 and the abnormal signal display light 90 are all connected to a high level through the second end of the selector. Therefore, no matter how the other end of the display light is controlled, the display light is extinguished at this time to realize router status detection.
