Description

Technical Field

[0001] This utility model relates to the field of server communication module switching, and more specifically, to a communication module switching device. Background Technology

[0002] In edge computing scenarios, customers may require different communication modules (e.g., 5G, 4G, and Wi-Fi modules), but they generally won't use two modules simultaneously. This would lead to a waste of Peripheral Component Interconnect Express (PCIe) resources and increased power consumption. Currently, the network performance of each communication module is evaluated by monitoring and analyzing signal quality data collected by sensors, allowing data communication to be switched to the module with the best network performance. However, this still increases design costs and overall power consumption. Utility Model Content

When the integrated circuit card is detached from the connection component 13, the on / off structure 1301 disconnects the first level adjustment pin 1302 and the first pin 1101 in the selection module 11, resulting in a high level for the connection component 13.

The switching module 14 is connected to the third pin 1104 in the selection module 11 via the fourth pin 1401. The switching module 14 is connected to N communication modules 2 via the N fifth pins 1402, wherein one fifth pin 1402 is connected to one communication module 2. The switching module 14 receives a target signal via the sixth pin 1403. The target signal is sent by the central processing unit and is used to indicate the working state of the switching module 14.

[0009] In an exemplary embodiment, the body 1 further includes a level adjustment circuit 15, wherein one end of the level adjustment circuit 15 is connected to the third pin 1104, and the other end is connected to the first communication module to be level adjusted among the N communication modules 2.

[0012] In an exemplary embodiment, the first communication module is also connected to the third pin 1104 and one of the N fifth pins 1402 included in the switching module 14.

[0013] In an exemplary embodiment, the target communication module 21 includes a tenth pin 2101 and an eleventh pin 2102. The tenth pin 2101 is connected to the third pin 1104.

[0023] To enable those skilled in the art to better understand the present invention, the technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort should fall within the protection scope of the present invention.

[0024] It should be noted that the terms "first," "second," etc., in the specification, claims, and accompanying drawings of this utility model are used to distinguish similar objects and are not necessarily used to describe a specific order or sequence. It should be understood that such data can be interchanged where appropriate so that the embodiments of the utility model described herein can be implemented in orders other than those illustrated or described herein. Furthermore, the terms "comprising" and "having," and any variations thereof, are intended to cover non-exclusive inclusion; for example, a process, method, system, product, or apparatus that comprises a series of steps or units is not necessarily limited to those steps or units explicitly listed, but may include other steps or units not explicitly listed or inherent to such processes, methods, products, or apparatus.

[0025] To address the issues of resource waste and high power consumption during communication module switching in related technologies, this invention provides a communication module switching device, which is deployed in a server and powered by the server.

[0026] like Figure 1 As shown, the switching device includes a main body 1 and a communication module 2 that provides wireless communication services to the server. The main body 1 includes a selection module 11, which is connected to a control component 12 and a connection component 13. The selection module 11 is used to generate a switching level through the control component 12 or the connection component 13. The switching level is used to turn on the target communication module 21 in N of the communication modules 2 to provide wireless communication services to the server. The communication module 2 includes N communication sub-modules, where N is a natural number greater than 1.

[0027] Optionally, the device in this embodiment of the present invention can be applied in edge scenarios, and the server in this embodiment of the present invention includes, but is not limited to, an edge server.

[0028] Optionally, the N communication modules 2 in this embodiment of the present invention include, but are not limited to, 4G modules, 5G modules, and WIFI modules.

[0029] Optionally, the selection module 11 in this embodiment of the present invention is a device capable of input selection, including but not limited to a 2-to-1 multiplexer (MUX2:1).

[0030] Optionally, the control component 12 in this embodiment of the present invention can be a device with automatic control function, including but not limited to the Baseboard Management Controller (BMC).

[0031] Optionally, the connection component 13 in this embodiment of the present invention can be a component of an integrated circuit card, including but not limited to a Subscriber Identity Module (SIM) connector.

[0032] This invention, through its embodiment, incorporates a selection module 11, a connection component 13, and a control component 12 within the main body 1. A switching level is generated via the control component 12 or the connection component 13, allowing the target communication module 21 in the communication module 2 to be activated based on actual conditions, thereby providing wireless communication services to the server. This solves the problems of resource waste and high power consumption when switching communication modules 2 in related technologies, achieving the effect of reducing server hardware resource consumption and improving resource utilization.

[0033] like Figure 2 As shown, the connection component 13 includes an on / off structure 1301, a first level adjustment pin 1302, a second level adjustment pin 1303, and an integrated circuit card detachably mounted on the connection component 13. The on / off structure 1301 is used to adjust the level between the connection component 13 and the selection module 11. When the integrated circuit card is installed on the connection component 13, the on / off structure 1301 conducts the first level adjustment pin 1302 and the first pin 1101 in the selection module 11, and the second level adjustment pin 1303 is grounded through the first device 1304, and the connection component 13 generates a low level. When the integrated circuit card is removed from the connection component 13, the on / off structure 1301 disconnects the first level adjustment pin 1302 and the first pin 1101 in the selection module 11, and the connection component 13 generates a high level.

[0034] Optionally, the on / off structure 1301 in this embodiment of the present invention is a structure that can adjust the level between the connection component 13 and the selection module 11, including but not limited to a switch, transistor, and diode.

[0035] Optionally, the integrated circuit card in this embodiment of the present invention can be a SIM card.

[0036] Optionally, the first device 1304 in this embodiment of the present invention is a device that can control current, including but not limited to a resistor, transistor, and diode.

[0037] In some implementations, embodiments of this utility model can be used to switch between a 5G module and a WIFI module. For example, the integrated circuit card is a SIM card, the connection component 13 is a SIM card connector, the SIM card connector is normally open (i.e., when no SIM card is inserted, the switch inside the SIM card connector is off (i.e., in a "normally open" state)), the on / off structure 1301 is a switch, the first device 1304 is a resistor, when no SIM card is inserted, a pull-up resistor is externally set on the second level adjustment pin 1303, and the connection component 13 generates a high level; after the SIM card is inserted, the switch inside the connection component 13 closes, the second level adjustment pin 1303 is grounded through the resistor, and the connection component 13 generates a low level.

[0038] Through the on / off structure 1301 in the connection component 13 of this embodiment, the level signal can be adjusted based on the insertion / removal status of the integrated circuit card. When the integrated circuit card is inserted, the on / off structure 1301 connects the first level adjustment pin 1302 to the selection module 11, while the second level adjustment pin 1303 is grounded through the first device 1304, generating a low-level signal. Conversely, when the integrated circuit card is removed, the connection is interrupted, generating a high-level signal. This mechanism realizes automatic switching based on the physical state of the integrated circuit card, eliminating the need for additional signal acquisition hardware and reducing system complexity and cost. Simultaneously, by automatically adjusting the level, the power state of the target communication module 21 is effectively controlled, reducing unnecessary power consumption and improving the energy efficiency of the server.

[0039] like Figure 2 As shown, the control component 12 is connected to the second pin 1102 in the selection module 11; when the control component 12 is connected to the selector 1103 in the selection module 11, the control component 12 is used to select the third pin 1104 to be connected to the first pin 1101, or to select the third pin 1104 to be connected to the second pin 1102 through the selector 1103.

[0040] Optionally, in this embodiment of the present invention, the selector 1103 is disposed in the selection module 11, including but not limited to pins, digital multiplexers, and analog multiplexers.

[0041] Optionally, the control component 12 in this embodiment of the present invention may be a BMC.

[0042] In some implementations, this utility model embodiment can be used to switch between a 5G module and a WIFI module. For example, the integrated circuit card is a SIM card, the connection component 13 is a SIM card connector, and the control component 12 is a BMC. The first pin 1101 is connected to the BMC, and the second pin 1102 is connected to the SIM card connector. When the input of the selection module 11 is selected by the BMC, when the selector receives a high level, the third pin 1104 is connected to the first pin 1101. The switching between the 5G module and the WIFI module can be determined by the state of the connection component 13. When the selector receives a low level, the third pin 1104 is connected to the second pin 1102. The switching between the 5G module and the WIFI module is controlled by the BMC. Therefore, when the user needs to select which module to use, a low level can be sent to the selector through the BMC.

[0043] Through this embodiment of the utility model, when the control component 12 is connected to the selector in the connection component 13, the control component 12 can select whether the third pin 1104 is connected to the first pin 1101 or the third pin 1104 is connected to the second pin 1102. Users can use the control component 12 to remotely control the switching of the communication module, which improves the convenience of management and the flexibility of the system.

[0044] like Figure 2 As shown, the main body 1 also includes a switching module 14, wherein one end of the switching module 14 is connected to the third pin 1104 in the selection module 11, and the other end is connected to N communication modules 2, wherein one fifth pin 1402 is connected to one communication module 2, and the switching module 14 is used to turn on the target communication module 21 by the switching level transmitted through the third pin 1104.

[0045] Optionally, in edge scenarios, the switching module 14 in this embodiment of the present invention can be a PCIe switching chip.

[0046] Optionally, in this embodiment of the present invention, the third pin 1104 of the selection module 11 outputs a switching control signal for selecting the communication module.

[0047] Through the switching module 14 in this embodiment of the present invention, the target communication module 21 can be selected according to the switching level signal of the selection module 11, thereby realizing the effective use of resources. Only one related resource needs to be occupied, saving the hardware cost and space resources of the server, and improving the overall performance and efficiency of the system.

[0048] like Figure 2 As shown, the switching module 14 includes a fourth pin 1401, N fifth pins 1402, and a sixth pin 1403. The switching module 14 is connected to the third pin 1104 of the selection module 11 via the fourth pin 1401. The switching module 14 is connected to the N communication modules 2 via the N fifth pins 1402. The switching module 14 receives a target signal via the sixth pin 1403. The target signal is sent by the central processing unit and is used to indicate the working status of the switching module 14.

[0049] In some implementations, this utility model embodiment can be used to switch between a 5G module and a WIFI module. The integrated circuit card is a SIM card, the connection component 13 is a SIM card connector, the control component 12 is a BMC, the target signal is sent by the central processing unit (CPU), and the switching module 14 is connected to the third pin 1104 in the selection module 11 through the fourth pin 1401. Based on the high or low level of the level sent by the third pin 1104, the fifth pin 1402 and the sixth pin 1403 are selected to be connected, that is, the target communication module 21 is selected. Specifically, when the fourth pin 1401 is low, the sixth pin 1403 is connected to the fifth pin 1402 corresponding to the 5G module, and when the fourth pin 1401 is high, the sixth pin 1403 is connected to the fifth pin 1402 corresponding to the WIFI module.

[0050] Through this embodiment of the utility model, the fourth pin 1401 connected to the selection module 11, the N fifth pins 1402 connected to the communication module, and the sixth pin 1403 for receiving the target signal from the central processing unit ensure the correct working state of the switching module 14 and the precise control of the target communication module 21, guarantee the accuracy of communication module switching, avoid switching failures caused by signal misreading, and further improve the reliability of the system and the stability of data transmission.

[0051] like Figure 2 As shown, the main body 1 also includes a level adjustment circuit 15, wherein one end of the level adjustment circuit 15 is connected to the third pin 1104, and the other end is connected to the first communication module to be level adjusted among the N communication modules 2. The level adjustment circuit 15 is used to adjust the level of the first communication module based on the level generated by the selection module 11.

[0052] Optionally, the level adjustment circuit 15 in this embodiment of the present invention is used to adjust the level input to the communication module.

[0053] Optionally, when the server includes more than two communication sub-modules, multiple level adjustment circuits 15 will be set according to actual needs.

[0054] In some implementations, this utility model embodiment can be used to switch between a 5G module and a WIFI module. The integrated circuit card is a SIM card, the connection component 13 is a SIM card connector, the control component 12 is a BMC, the 5G module is connected to the third pin 1104 in the selection module 11, and a level adjustment circuit 15 is set in the connection circuit. The WIFI module is connected to the third pin in the selection module 11, and a level adjustment circuit 15 is not set in the connection circuit. When the 5G module or the WIFI module receives a low level, the module is turned off; when the 5G module or the WIFI module receives a high level, the module is turned on. When the SIM card is inserted, the switching control signal output from the third pin 1104 is at a low level. The switching module 14 is connected to the 5G module. The switching control signal is changed to a high level by the level adjustment circuit 15 and connected to the 5G module. The 5G module is turned on and works normally. The WIFI module receives a low level and turns off, reducing power consumption. When the SIM card is removed, the switching control signal output from the third pin 1104 is at a high level. The switching module 14 is connected to the WIFI module. The switching control signal is changed to a low level by the level flip circuit 35 and connected to the 5G module. The 5G module is turned off. The WIFI module receives a high level and works normally. This realizes the switching between the 5G module and the WIFI module by controlling the insertion and removal of the SIM card.

[0055] The level adjustment circuit 15 in this embodiment is connected between the selection module 11 and the communication module to adjust the level signal from the selection module 11, ensuring that different communication modules can correctly identify and respond to the switching signal, wake up the target communication module 21 based on the actual situation, and shut down the other communication modules, thereby reducing resource consumption and enhancing the system's compatibility and communication quality.

[0056] like Figure 3 As shown, the level adjustment circuit 15 includes a seventh pin 1501, an eighth pin 1502, a ninth pin 1503, and a transistor 1504. The seventh pin 1501 is connected to the third pin 1104, the eighth pin 1502 is connected to the first communication module, the ninth pin 1503 is connected to the power supply, the gate of the transistor 1504 is connected to the seventh pin 1501, the source 1505 of the transistor 1504 is grounded, and the drain of the transistor 1504 is connected to the eighth pin 1502. The transistor 1504 is used to adjust the level of the first communication module based on the level generated by the selection module 11.

[0057] Optionally, the transistor in this embodiment of the present invention can be selected to conduct based on the voltage difference between the gate and the source, including but not limited to N-channel metal-oxide-semiconductor field-effect transistors (N-MOSFETs).

[0058] In some implementations, when pin 7 (1501) is high, the transistor's gate is also high, and the transistor's source is grounded (low). At this time, the voltage difference between the gate and source is greater than the cutoff voltage, so the transistor is turned on. The transistor's drain and source are also connected (low), and pin 8 (1502) outputs a low level. When pin 7 (1501) is low, the transistor's gate is also low, and the transistor's source is grounded (low). At this time, the voltage difference between the gate and source is less than the cutoff voltage, so the transistor is turned off, and pin 8 (1502) outputs a high level.

[0059] Through the level adjustment circuit 15 in this embodiment of the present invention, the seventh pin 1501 connected to the selection module 11, the eighth pin 1502 connected to the communication module, the ninth pin 1503 connected to the power supply, and the transistor for level conversion, can quickly respond to level changes, ensure seamless switching between communication modules, reduce signal delay, and improve the speed and efficiency of communication switching.

[0060] like Figure 3 As shown, the level adjustment circuit 15 includes a second device 1506, a third device 1507, and a fourth device 1508. One end of the second device 1506 is connected to the gate of the transistor 1504, and the other end of the second device 1506 is connected to the source of the transistor 1504. The third device 1507 is used to limit the current passing through the transistor 1504, and the fourth device 1508 is used to filter the current from the seventh pin 1501.

[0061] Optionally, the second device 1506 in this embodiment of the present invention is used to connect the gate and source of transistor 1504, mainly for rapid discharge of electrostatic discharge (ESD). The impedance between the gate and source of transistor 1504 is relatively large, so as long as there is a small amount of static electricity between the gate and source, a small amount of current will flow through it, and a very high voltage will be generated across the equivalent capacitance between the gate and source. At this time, the second device 1506 can be used for rapid discharge. The second device 1506 includes, but is not limited to, a resistor.

[0062] Optionally, the third device 1507 in this embodiment of the invention is used to limit the current passing through the transistor 1504, including but not limited to a resistor.

[0063] Optionally, the fourth device 1508 in this embodiment of the present invention is used to filter the current from the seventh pin 1501, to filter AC current and retain DC current. The fourth device 1508 includes, but is not limited to, a capacitor, a filter, and a diode.

[0064] The second device 1506, the third device 1507, and the fourth device 1508 in the level adjustment circuit 15 of this utility model embodiment are used for signal protection, current limiting, and filtering, which improves the robustness and anti-interference ability of the level adjustment circuit 15, protects the circuit from electrostatic discharge damage, and the current limiting and filtering functions further ensure the stability of the signal and the safe operation of the communication module.

[0065] like Figure 4 As shown, the first communication module is connected to the third pin 1104 and one of the N fifth pins 1402 included in the switching module 14.

[0066] Through this embodiment of the utility model, the stable connection between the first communication module and the main body 1 ensures the continuity of signal transmission and the reliability of communication services, enabling the communication module to respond quickly to switching commands and improving the efficiency and success rate of switching operations.

[0067] like Figure 4 As shown, the target communication module 21 includes a tenth pin 2101 and an eleventh pin 2102. The tenth pin 2101 is connected to the third pin 1104. When the tenth pin 2101 receives a high level, the target communication module 21 starts working. The eleventh pin 2102 is connected to the fifth target pin 1402, which is one of N pins that corresponds to the target communication module 21.

[0068] Optionally, in this embodiment of the invention, the tenth pin 2101 is connected to the third pin 1104 to receive the output from the selection module 11.

[0069] Optionally, in this embodiment of the present invention, the eleventh pin 2102 is connected to the fifth target pin, and the signal emitted by the switching module 14 is used to determine whether the target communication module 21 is working properly.

[0070] Through the response mechanism of the target communication module 21 in this embodiment of the present invention, the working mode is activated by receiving a high-level signal through the tenth pin 2101, and the module is connected to the specific fifth pin 1402 of the switching module 14 through the eleventh pin 2102, so as to achieve precise control of the module, ensure that it can be put into use immediately when needed, avoid unnecessary startup delay, improve communication response speed, effectively save power, extend server running time, and reduce overall power consumption.
