Description

Technical Field

[0001] This application relates to the field of server technology, and more particularly to a server. Background Technology

[0002] Server chassis typically contain circuit boards, electronic devices, and high-speed signal cables. These cables inevitably come into contact with the circuit boards and electronic equipment. Usually, the cables are wrapped in braided mesh. However, the rapid temperature changes within the system chassis cause condensation to easily form on the braided mesh. When this braided mesh comes into contact with the circuit boards or electronic equipment, it can easily cause circuit malfunctions or abnormalities, leading to electronic equipment failure or damage.

[0003] Therefore, accurately detecting condensation within the server is crucial. Summary of the Invention

[0004] This application provides a server that can accurately detect whether condensation exists inside the server.

[0005] To achieve the above objectives, the embodiments of this application adopt the following technical solutions:

[0006] In a first aspect, a server is provided, comprising: a first circuit board and a second circuit board, the first circuit board and the second circuit board being connected by a first cable; the first cable includes a signal transmission line and a humidity detection line wrapped by a sheathing layer; the signal transmission line is used to transmit communication signals, and the humidity detection line is used to transmit humidity detection signals; the first circuit board and the second circuit board transmit communication signals through the signal transmission line; the first circuit board is used to determine the humidity detection result within the server based on the humidity detection signal.

[0007] In a server, the first circuit board (motherboard) and the second circuit board (backplane) typically rely on cables to transmit communication signals. If condensation or leakage occurs within the server, it can cause varying degrees of wetting to the cable sheathing. Therefore, the server provided in this application uses a first cable to connect the first and second circuit boards. The humidity detection line in this first cable can sense the humidity of the sheathing, thereby detecting the humidity level inside the server. The humidity detection signal transmitted by the humidity detection line changes during transmission, allowing the first circuit board to determine the humidity level within the server based on the humidity detection signal. In this way, this application eliminates the need for additional humidity detection equipment to accurately determine the humidity level inside the server, and also reduces server configuration costs.

[0008] In one possible implementation, the resistance of the humidity detection line is related to the humidity of the environment in which the cable is located; the humidity detection line in the first cable includes a first detection line and a second detection line; the first end of the first detection line is connected to the first detection terminal of the first circuit board, and the first end of the second detection line is connected to the second detection terminal of the first circuit board; the second ends of the first detection line and the second detection line are connected through the second circuit board; the first circuit board is used to determine the humidity detection result based on the voltage difference between the humidity detection signal at the first detection terminal and the second detection terminal.

[0009] In this implementation, the resistance of the humidity detection line is related to the humidity of the environment in which the cable is located, and the voltage across the humidity detection line is also related to its resistance, thus affecting the signal voltage of the humidity detection signal transmitted by the line. Therefore, the signal voltage of the humidity detection signal is affected by the humidity of the server's internal environment. The second end of the first detection line is connected to the second end of the first detection line in series to form a single detection line. The first end of the first detection line is connected to the first detection terminal of the first circuit board, and the first end of the second detection line is connected to the second detection terminal of the first circuit board. In this way, the first and second detection lines of the humidity detection line in the first cable, together with the first circuit board, form a loop. The first circuit board can transmit a humidity detection signal through the first detection terminal and receive the humidity detection signal transmitted through the first and second detection lines through the second detection terminal. If the humidity detection line senses the humidity outside the wrapping layer, its transmitted humidity detection signal will change. Thus, there is a voltage difference between the signal voltage detected by the first detection terminal and the signal voltage detected by the second detection terminal of the first circuit board. Based on this, the first circuit board can determine the humidity detection result based on the voltage difference between the humidity detection signal at the first and second detection terminals.

[0010] In one possible implementation, the first circuit board includes a voltage detection circuit and a controller connected to each other; the two ends of the voltage detection circuit are a first detection end and a second detection end, respectively, and the voltage detection circuit is used to detect the voltage difference between the humidity detection signal and the second detection end; the controller is used to determine the humidity detection result based on the voltage difference.

[0011] In the server, the first circuit board includes a voltage detection circuit and a controller connected to each other. The voltage detection circuit has a first detection terminal and a second detection terminal, respectively. It is understood that if humidity is present in the server's environment, the humidity detection signal will change. Thus, the signal voltage detected by the first detection terminal and the signal voltage detected by the second detection terminal will differ. The voltage detection circuit can determine the humidity detection result based on the voltage difference between the first and second detection terminals. The controller can determine the humidity detection result based on this voltage difference.

[0012] In one possible implementation, the controller is configured to determine that the humidity detection result is normal when the voltage difference is greater than or equal to a voltage threshold; and to determine that the humidity detection result is abnormal when the voltage difference is less than the voltage threshold; the abnormal humidity includes the presence of condensation in the environment and / or the presence of leakage in the environment.

[0013] Because the resistance of the humidity detection cable is negatively correlated with the humidity of the environment in which the cable is located, the voltage difference across the two ends of the humidity detection cable is also negatively correlated with the humidity of the environment. That is, the higher the humidity of the environment, the lower the resistance of the humidity detection cable, and the smaller the voltage difference between the first and second detection terminals. Therefore, the controller can determine the humidity detection result based on the voltage difference. If the voltage difference is greater than or equal to a voltage threshold, the humidity detection result is determined to be normal within the server environment. If the voltage difference is less than the voltage threshold, the humidity detection result is determined to be abnormal within the server environment.

[0014] In another possible implementation, the first circuit board and the second circuit board are also connected by a second cable; the second cable includes a signal transmission line and a humidity detection line wrapped by a sheathing layer; the resistance of the humidity detection line is related to the humidity of the environment in which the cable is located; the humidity detection line in the second cable includes a third detection line and a fourth detection line; the first end of the first detection line is connected to the first detection terminal of the first circuit board, and the first end of the second detection line is connected to the second detection terminal of the first circuit board; the first end of the third detection line is connected to the third detection terminal of the first circuit board, and the first end of the fourth detection line is connected to the fourth detection terminal of the first circuit board; the second end of the first detection line and the second end of the third detection line are connected by a first connector and a second connector of the second circuit board; the second end of the second detection line and the second end of the fourth detection line are connected by a first connector and a second connector of the second circuit board; the first circuit board is used to determine the humidity detection result based on the voltage difference of the humidity detection signal between the first detection terminal and the second detection terminal, and / or the voltage difference of the humidity detection signal between the third detection terminal and the fourth detection terminal.

[0015] When the first circuit board and the second circuit board are connected via a first cable and a second cable, the humidity detection lines in the first cable include a first detection line and a second detection line, and the humidity detection lines in the second cable include a third detection line and a fourth detection line. The second ends of the first and third detection lines are connected in series via a first connector and a second connector on the second circuit board to form a single detection line. The second ends of the second and fourth detection lines are also connected in series via a first connector and a second connector on the second circuit board to form a single detection line. When the server starts, the first circuit board can transmit a humidity detection signal through the first end of the first detection line. The first and third detection lines transmit this humidity detection signal, and the humidity detection signal changes. Similarly, the first circuit board can transmit a humidity detection signal through the first end of the fourth detection line. The fourth and second detection lines transmit this humidity detection signal, and the humidity detection signal also changes. In this implementation, the humidity detection signal transmitted by the first circuit board through the first end of the first detection line is the same as the humidity detection signal transmitted through the first end of the fourth detection line. In this way, the first circuit board can detect the voltage difference between the humidity detection signal at the first and second detection terminals, and the voltage difference between the humidity detection signal at the third and fourth detection terminals, and determine the humidity detection result based on the voltage difference. It is understood that since the first and second cables are both located within the server, the degree of condensation / leakage experienced by the sheathing layers of the first and second cables within the server may differ. The humidity detection result determined by the first circuit board based on the voltage difference between the humidity detection signal at the first and second detection terminals, and / or the voltage difference between the humidity detection signal at the third and fourth detection terminals, is more accurate.

[0016] In one possible implementation, the first circuit board includes: a first voltage detection circuit, a second voltage detection circuit, and a controller; the first voltage detection circuit and the second voltage detection circuit are respectively connected to the controller; the two ends of the first voltage detection circuit are a first detection end and a second detection end, respectively, and the first voltage detection circuit is used to detect a first voltage difference of the humidity detection signal between the first detection end and the second detection end; the two ends of the second voltage detection circuit are a third detection end and a fourth detection end, respectively, and the second voltage detection circuit is used to detect a second voltage difference of the humidity detection signal between the third detection end and the fourth detection end; the controller is used to determine the humidity detection result based on the first voltage difference and the second voltage difference.

[0017] In the server, the first circuit board includes a first voltage detection circuit, a second voltage detection circuit, and a controller. The first voltage detection circuit has a first detection terminal and a second detection terminal at its two ends, and the second voltage detection circuit has a third detection terminal and a fourth detection terminal at its two ends. In this implementation, the humidity detection signal emitted by the first voltage detection circuit through its first detection terminal is the same as the humidity detection signal emitted by the second voltage detection circuit through its fourth detection terminal. The humidity detection signal emitted by the first voltage detection circuit is transmitted to the second voltage detection circuit via the first and third detection lines. Conversely, the humidity detection signal emitted by the second voltage detection circuit is transmitted to the first voltage detection circuit via the fourth and second detection lines. If humidity exists in the server's environment, both sets of humidity detection signals will change. Thus, the first voltage detection circuit can determine a first voltage difference between the humidity detection signal at the first and second detection terminals, and the second voltage detection circuit can determine a second voltage difference between the humidity detection signal at the third and fourth detection terminals, allowing the controller to determine the humidity detection result based on the first and second voltage differences.

[0018] In one possible implementation, the controller is configured to determine that the humidity detection result is normal within the server when a first voltage difference is greater than or equal to a voltage threshold and a second voltage difference is greater than or equal to a voltage threshold; and to determine that the humidity detection result is abnormal within the server when a first voltage difference is less than a voltage threshold and / or a second voltage difference is less than a voltage threshold; the abnormal humidity includes the presence of condensation in the environment and / or the presence of leakage in the environment.

[0019] Because the resistance of the humidity detection cable is negatively correlated with the humidity of the environment in which the cable is located, the voltage difference across the two ends of the humidity detection cable is also negatively correlated with the humidity of the environment. That is, the higher the humidity of the environment, the lower the resistance of the humidity detection cable, and the smaller the voltage difference between the detection ends. Therefore, the controller can determine that the humidity detection result is normal within the server if both the first and second voltage differences are greater than or equal to a voltage threshold. Conversely, the controller can determine that the humidity detection result is abnormal within the server if the first voltage difference is less than the voltage threshold, and / or the second voltage difference is less than the voltage threshold. Thus, even if only the first voltage difference is too small, or only the second voltage difference is too small, an abnormal humidity level within the server can be detected, allowing for timely alarm issuance and server protection.

[0020] In one possible implementation, the controller includes: a Baseboard Management Controller (BMC), a Complex Programmable Logic Device (CPLD), or a Central Processing Unit (CPU).

[0021] BMC, CPLD, and CPU can all determine the humidity detection result based on the voltage difference. Therefore, the controller can be a BMC, a CPLD, or a CPU. All three can determine the humidity detection result based on the voltage difference.

[0022] In one possible implementation, the first circuit board further includes: a third connector and a fourth connector; a first end of the first detection line is connected to a first detection end of the first circuit board via the third connector; a first end of the second detection line is connected to a second detection end of the first circuit board via the third connector; a first end of the third detection line is connected to a third detection end of the first circuit board via the fourth connector; and a first end of the fourth detection line is connected to a fourth detection end of the first circuit board via the fourth connector.

[0023] Understandably, the first circuit board (i.e., the motherboard) includes connectors to connect to the first and second cables, thereby enabling connection to the second circuit board.

[0024] In one possible implementation, the connector includes: a first connector, a second connector, a third connector, and a fourth connector; the connector includes: a signal pin and a detection pin; the signal pin is used to connect to a signal transmission line; the detection pin is used to connect to a humidity detection line.

[0025] It is understood that connectors typically include pins for connecting to transmission lines. In this application, the connector includes signal pins and detection pins, wherein the signal pins are used to connect to a signal transmission line, and the detection pins are used to connect to a humidity detection line.

[0026] Secondly, a cable is provided for connecting a first circuit board. The cable includes a signal transmission line, a humidity detection line, and a sheathing layer. The sheathing layer covers the signal transmission line and the humidity detection line. The signal transmission line is used to transmit communication signals sent or received by the first circuit board. The humidity detection line is used to transmit humidity detection signals. The humidity detection signals are used by the first circuit board to determine the humidity detection results of the server's internal environment.

[0027] The first circuit board typically relies on signal transmission lines within the cable to send and receive communication signals. Condensation or leakage in the cable's environment can cause varying degrees of wetting of the cable sheath. Therefore, a humidity detection line is introduced into the cable to sense the humidity of the sheath, thereby detecting the humidity level outside the sheath and converting it into a humidity detection signal, which is then transmitted to the first circuit board. The first circuit board then determines the humidity detection result. This eliminates the need for additional humidity detection equipment, reducing configuration costs.

[0028] In one possible implementation, the resistance of the humidity detection line is related to the humidity of the environment in which the cable is located; the signal voltage of the humidity detection signal is used by the first circuit board to determine the humidity detection result.

[0029] In one possible implementation, the humidity detection line includes a first detection line and a second detection line; a first end of the first detection line is used to connect to a first detection terminal of a first circuit board, and a first end of the second detection line is used to connect to a second detection terminal of the first circuit board; a second end of the first detection line is used to connect to a second end of the second detection line; the first circuit board is used to determine the humidity detection result based on the voltage difference between the humidity detection signal at the first detection terminal and the second detection terminal.

[0030] In one possible implementation, the cable includes multiple signal transmission lines, with at least one signal transmission line being at a distance greater than the distance between the humidity detection line and the wrapping layer.

[0031] Because the humidity detection line in the cable senses the humidity of the sheath layer, and thus the humidity outside the sheath layer, the closer the humidity detection line is to the sheath layer, the closer the humidity detected is to the humidity of the environment in which the cable is located. Furthermore, the humidity detection signal converted by the humidity detection line more accurately reflects the humidity of the server's internal environment. In the case of a cable containing multiple signal transmission lines, at least one signal transmission line is farther from the sheath layer than the humidity detection line. Thus, compared to the signal transmission lines, the humidity detection line is closer to the sheath layer, and the humidity detection signal converted by the humidity detection line more accurately reflects the humidity of the environment in which the cable is located. Consequently, the humidity detection result determined by the first circuit board based on the humidity detection signal is more accurate.

[0032] In one possible implementation, the humidity detection line is in contact with the wrapping layer, and / or, there is a gap between the humidity detection line and the wrapping layer.

[0033] Because the humidity detection line in the cable senses the humidity of the sheath layer, and thus the humidity outside the sheath layer, if condensation or leakage occurs in the environment where the cable is located, the humidity detection line within the sheath layer will detect the humidity regardless of its position. This affects the humidity detection signal converted by the line, allowing the first circuit board to determine the humidity detection result. Therefore, whether the humidity detection line is in contact with the sheath layer or there is a gap between them, the first circuit board can determine the humidity detection result of the server's internal environment based on the humidity detection signal transmitted by the line.

[0034] In one possible implementation, the humidity detection wire is wound around the signal detection wire.

[0035] Because the humidity detection line in the cable senses the humidity of the sheath layer, and thus the humidity outside the sheath layer, the larger the contact area between the humidity detection line and the sheath layer, the closer the humidity detected by the line is to the humidity of the environment in which the cable is located. Furthermore, the humidity detection signal converted by the line is more accurate in reflecting the humidity of the environment. It is understandable that, compared to other setups, the contact area between the humidity detection line and the sheath layer is maximized when the humidity detection line is wrapped around the signal detection line. This results in a more accurate humidity detection signal, better reflecting the humidity of the environment, and consequently, a more precise humidity detection result determined by the first circuit board based on the humidity detection signal.

[0036] In one possible implementation, the resistance of the humidity sensing line is negatively correlated with the humidity of the environment in which the cable is located.

[0037] In this implementation, the resistance of the humidity detection line is negatively correlated with the humidity of the environment in which the cable is located. That is, the higher the humidity of the environment, the lower the resistance of the humidity detection line, and the smaller the signal voltage of the humidity detection signal (i.e., the voltage difference between the first end of the first detection line and the first end of the second detection line). Therefore, the first circuit board can determine the humidity detection result based on the voltage difference between the first and second detection ends of the humidity detection signal.

[0038] Thirdly, a humidity detection method is provided, applied to a first circuit board in a server as described in the first aspect, the server further comprising: a first cable; the first cable comprising a signal transmission line and a humidity detection line wrapped by a sheathing layer; the method comprising: acquiring a humidity detection signal transmitted in the humidity detection line; and determining a humidity detection result within the server based on the humidity detection signal.

[0039] In one possible implementation, the resistance of the humidity detection line is related to the humidity of the environment in which the cable is located; determining the humidity detection result of the cable environment based on the humidity detection signal includes: determining the humidity detection result based on the signal voltage of the humidity detection signal.

[0040] In one possible implementation, the humidity detection line includes a first detection line and a second detection line; a first end of the first detection line is connected to a first detection terminal of a first circuit board, and a first end of the second detection line is connected to a second detection terminal of the first circuit board; the second ends of the first detection line and the second detection line are connected through a second circuit board; determining the humidity detection result based on the signal voltage of the humidity detection signal includes: determining the humidity detection result based on the voltage difference between the humidity detection signal at the first detection terminal and the second detection terminal.

[0041] In one possible implementation, the humidity detection result is determined based on the voltage difference between the first detection terminal and the second detection terminal, including: if the voltage difference is greater than or equal to a voltage threshold, the humidity detection result is determined to be normal humidity in the environment where the cable is located; if the voltage difference is less than the voltage threshold, the humidity detection result is determined to be abnormal humidity in the environment where the cable is located; abnormal humidity includes condensation in the environment and / or leakage in the environment.

[0042] The technical effects brought about by the third aspect can be found in the technical effects brought about by the first and second aspects, and will not be repeated here. Attached Figure Description

Those skilled in the art will understand that the terms "first" and "second" do not limit the quantity or execution order, and that "first" and "second" are not necessarily different.

Specifically, the use of terms such as "exemplary" or "for example" is intended to present related concepts in a concrete manner for ease of understanding.

[0052] For ease of understanding, the relevant technical terms involved in the embodiments of this application will be introduced below.

[0053] Condensation: Water droplets, tiny water droplets. When water vapor in the air cools down, it condenses into water droplets because the air temperature is below the saturation temperature, thus forming condensation. It is formed when water vapor condenses on a cooled surface. Condensation occurs when water vapor leaves the air and the air temperature is below the saturation temperature.

[0054] Cable: Cables are used to connect circuit boards inside a server to transmit communication signals.

[0055] Humidity detection line: The resistance of a humidity detection line is related to the humidity of its environment. A humidity detection line can be a water-resistant rope.

[0056] The following provides an exemplary description of the application scenarios of the embodiments of this application.

[0057] Inside a computer case (such as a server chassis), there are typically circuit boards containing electronic components. When the humidity in the air is high, the temperature changes that occur when the equipment is turned on and off. These short-term temperature changes cause moisture in the air to adhere to the circuit boards or electronic devices, easily forming condensation (also known as water droplets). Condensation can cause short circuits in the circuit boards or electronic devices, leading to malfunctions or damage.

[0058] Furthermore, the chassis contains cables, which inevitably come into contact with circuit boards and electronic devices. Moisture in the air easily condenses on the cable braid (i.e., the sheathing layer). When the cable braid comes into contact with circuit boards or electronic devices, it can easily cause circuit malfunctions or abnormalities, leading to electronic component failure or damage.

[0059] The server provided in this application allows for real-time monitoring of humidity levels within the server. In the server provided by this application, circuit boards are connected via cables, and the humidity detection signal transmitted by the humidity detection lines in the cables is affected by condensation / leakage. Furthermore, the circuit board (which may be a motherboard) connected to the cables can determine the humidity detection result within the server based on the humidity detection signal transmitted by the cables.

[0060] The server described below is an example of an embodiment of this application.

[0061] This application provides a server, which includes a first circuit board, a second circuit board, and cables.

[0062] The following describes the server provided in the embodiments of this application, taking the first circuit board as the motherboard and the second circuit board as the backplane as an example.

[0063] Figure 1 This is a schematic diagram of a server system architecture provided in an embodiment of this application.

[0064] like Figure 1 As shown, the server 1 includes: a first cable 101, a first circuit board 102, and a second circuit board 103.

[0065] The first circuit board 102 and the second circuit board 103 are connected by the first cable 101.

[0066] That is, one end of the first cable 101 is connected to the first circuit board 102, and the other end is connected to the second circuit board 103.

[0067] The first cable 101 includes: a signal transmission line wrapped with a sheathing layer ( Figure 1 (not shown in the image) Humidity detection line ( Figure 1The thick black line in the middle is the humidity detection line.

[0068] Specifically, such as Figure 1 As shown, the humidity detection line includes a first detection line and a second detection line.

[0069] The first end of the first detection line is connected to the first detection end of the first circuit board 102, the first end of the second detection line is connected to the second detection end of the first circuit board 102, and the second ends of the first detection line and the second detection line are connected through the second circuit board 103.

[0070] In some embodiments, the first end of the first detection line is connected to the first detection terminal of the first circuit board 102 via a connector, and the first end of the second detection line is connected to the second detection terminal of the first circuit board 102 via a connector. The second ends of the first detection line and the second ends of the second detection line are connected via a connector on the second circuit board 103.

[0071] Understandably, connectors typically include pins for connecting cables to a first circuit board and a second circuit board.

[0072] In this embodiment, the connector includes a signal pin and a detection pin. The signal pin is used to connect to a signal transmission line, and the detection pin is used to connect to a humidity detection line.

[0073] The first circuit board 102 also includes a first voltage detection circuit 1021 and a controller 1022 that are interconnected.

[0074] The controller 1022 can be a BMC, a CPLD, or a CPU.

[0075] The two ends of the first voltage detection circuit 1021 are the first detection end and the second detection end, respectively.

[0076] The aforementioned signal transmission line is used to transmit communication signals, and the humidity detection line is used to transmit humidity detection signals.

[0077] The resistance of the humidity detection line is related to the humidity of the environment in which the first cable 101 is located (i.e., the environment inside the server).

[0078] In this embodiment, the first circuit board 102 and the second circuit board 103 are connected by a first cable 101. The first circuit board 102 and the second circuit board 103 transmit communication signals through a signal transmission line in the first cable 101. The first circuit board 102 on the first circuit board 102 can receive or send communication signals through the signal transmission line. The first circuit board 102 and the second circuit board 103 transmit humidity detection signals through a humidity detection line in the first cable 101. The first circuit board 102 on the first circuit board 102 can determine the humidity detection result within the server 1 based on the humidity detection signal.

[0079] In one possible implementation, the resistance of the humidity detection line is related to the humidity of the environment in which the first cable 101 is located. In this case, the first circuit board 102 can determine the humidity detection result based on the signal voltage of the humidity detection signal.

[0080] It is understandable that the resistance of the humidity detection line is related to the humidity of the environment in which the first cable 101 is located, and the voltage across the humidity detection line is related to the resistance of the humidity detection line. Therefore, the voltage across the humidity detection line is related to the humidity of the environment in which the first cable 101 is located.

[0081] Example 1: If the resistance of the humidity detection line is negatively correlated with the humidity of the environment where the first cable 101 is located (i.e., inside server 1), the higher the humidity of the environment where the first cable 101 is located (more condensation, or more leakage), the lower the resistance of the humidity detection line and the lower the voltage across the humidity detection line.

[0082] Example 2: If the resistance of the humidity detection line is positively correlated with the humidity of the environment where the first cable 101 is located, the higher the humidity of the environment where the first cable 101 is located, the higher the resistance of the humidity detection line and the higher the voltage across the humidity detection line.

[0083] In such Figure 1 In the illustrated embodiment, the first detection line, the second detection line, the second circuit board 103, and the first circuit board 102 together form a loop. When the server 1 starts up, the first circuit board 102 can determine the humidity detection result based on the humidity detection signal transmitted by the humidity detection line.

[0084] Specifically, the first circuit board 102 can determine the humidity detection result based on the voltage difference between the first detection terminal and the second detection terminal of the humidity detection signal.

[0085] Understandably, the second end of the first detection line and the second end of the second detection line are connected in series via the second circuit board 103 to form a single detection line. The first end of the first detection line is connected to the first detection terminal and the second detection terminal of the first circuit board 102, respectively. In this way, the first circuit board 102 can determine the first signal voltage of the humidity detection signal at the first detection terminal and the second signal voltage at the second detection terminal. Furthermore, the first circuit board 102 can determine the humidity detection result based on the voltage difference between the first signal voltage and the second signal voltage.

[0086] Specifically, when the first circuit board 102 determines the humidity detection result based on the voltage difference between the first and second detection terminals of the humidity detection signal, the voltage detection circuit 1021 detects the voltage difference between the first and second detection terminals of the humidity detection signal. The controller 1022 then determines the humidity detection result based on the voltage difference.

[0087] When the voltage difference is greater than or equal to the voltage threshold, the controller 1022 can determine that the humidity of the environment where the cable 101 is located is normal. When the voltage difference is less than the voltage threshold, the controller 1022 can determine that the humidity of the environment inside the server 1 is abnormal.

[0088] Abnormal humidity includes: condensation in the environment inside server 1, and / or leakage in the environment inside server 1.

[0089] Figure 2 This is a schematic diagram of another server system architecture provided in an embodiment of this application.

[0090] like Figure 2 As shown, the server 2 includes: a first cable 2011 and a second cable 2012, a first circuit board 202 and a second circuit board 203.

[0091] One end of the first cable 2011 is connected to the first circuit board 202, and the other end is connected to the second circuit board 203.

[0092] One end of the second cable 2012 is connected to the first circuit board 202, and the other end is connected to the second circuit board 202.

[0093] Both the first cable 2011 and the second cable 2012 include: a signal transmission line wrapped by a sheathing layer. Figure 2 (not shown in the image) Humidity detection line ( Figure 2 The thick black line in the middle is the humidity detection line.

[0094] The humidity detection lines of both the first cable 2011 and the second cable 2012 include two detection lines.

[0095] The humidity detection lines of the first cable 2011 include a first detection line and a second detection line, and the humidity detection lines of the second cable 2012 include a third detection line and a fourth detection line. The first end of the first detection line is connected to the first detection terminal of the first circuit board 202; the first end of the second detection line is connected to the second detection terminal of the first circuit board 202; the first end of the third detection line is connected to the third detection terminal of the first circuit board 202; the first end of the fourth detection line is connected to the fourth detection terminal of the first circuit board 202; the second ends of the first and third detection lines are connected through the first connector 2031 and the second connector 2032 of the second circuit board 203; and the second ends of the second and fourth detection lines are connected through the first connector 2031 and the second connector 2032 of the second circuit board 203.

[0096] The first circuit board 202 includes a first voltage detection circuit 2021, a second voltage detection circuit 2022, and a controller 2023. The first circuit board 202 also includes a third connector 2024 and a fourth connector 2025.

[0097] The first voltage detection circuit 2021 and the second voltage detection circuit 2022 are respectively connected to the controller 2023. The specific structure of server 2 is as follows: Figure 2 As shown, the first end of the first detection line is connected to the first end of the first voltage detection circuit 2021 (i.e., the first detection end of the first circuit board 202) via the third connector 2024. The first end of the second detection line is connected to the second end of the first voltage detection circuit 2021 (i.e., the second detection end of the first circuit board 202) via the second connector 2024. The third end of the first voltage detection circuit 2021 is connected to the controller 2023. The first end of the third detection line is connected to the first end of the second voltage detection circuit 2022 (i.e., the third detection end of the first circuit board 202) via the fourth connector 2025. The first end of the fourth detection line is connected to the second end of the second voltage detection circuit 2021 (i.e., the fourth detection end of the first circuit board 202) via the fourth connector 2025.

[0098] The third terminal of the second voltage detection circuit 2022 is connected to the controller 2023.

[0099] The second end of the first detection line and the second end of the third detection line are connected through the first connector 2031 and the second connector 2032 of the second circuit board 203. The second end of the second detection line and the second end of the fourth detection line are connected through the first connector 2031 and the second connector 2032 of the second circuit board 203.

[0100] The first connector 2031 and the second connector 2032 are interconnected.

[0101] It is understood that the two ends of the first voltage detection circuit 2021 are the first detection end and the second detection end, respectively, and the two ends of the second voltage detection circuit 2022 are the third detection end and the fourth detection end, respectively.

[0102] In such Figure 2 In the illustrated embodiment, the second end of the first detection line and the second end of the third detection line are connected in series to form a single detection line via a first connector and a second connector on the second circuit board. Similarly, the second end of the second detection line and the second end of the fourth detection line are connected in series to form a single detection line via a first connector and a second connector on the second circuit board.

[0103] When server 2 starts up, the first circuit board 202 can transmit a first humidity detection signal through one port of the first voltage detection circuit 2021 (i.e., the first detection terminal of the first circuit board 202) and transmit a second humidity detection signal through one port of the second voltage detection circuit 2022 (i.e., the fourth detection terminal of the first circuit board 202). The first humidity detection signal and the second humidity detection signal are the same.

[0104] The first detection line and the third detection line transmit the first humidity detection signal to the second voltage detection circuit 2022 to obtain the third humidity detection signal (in order to distinguish between the transmitted and received first humidity detection signals, the received first humidity detection signal is named the third humidity detection signal).

[0105] The fourth detection line and the second detection line transmit the second humidity detection signal to the first voltage detection circuit 2021 to obtain the fourth humidity detection signal (in order to distinguish between the transmitted and received second humidity detection signals, the received second humidity detection signal is named the fourth humidity detection signal).

[0106] The first voltage detection circuit 2021 can determine the first voltage difference based on the first humidity detection signal detected by the first detection terminal and the third humidity detection signal detected by the second detection terminal. The second voltage detection circuit 2022 can determine the fourth voltage difference based on the second humidity detection signal detected by the third detection terminal and the fourth humidity detection signal detected by the fourth detection terminal.

[0107] Furthermore, the controller 2023, based on the aforementioned voltage difference, jointly determines the humidity detection result.

[0108] In this case, the process for determining the humidity detection result is the same as that described above. However, in this embodiment, a more accurate humidity detection result can be determined based on dual safeguards.

[0109] Specifically, if the first voltage difference is greater than or equal to the voltage threshold and the second voltage difference is greater than or equal to the voltage threshold, the humidity detection result is determined to be normal environmental humidity inside the server; if the first voltage difference is less than the voltage threshold and / or the second voltage difference is less than the voltage threshold, the humidity detection result is determined to be abnormal environmental humidity inside the server.

[0110] Abnormal humidity includes the presence of condensation in the environment, and / or the presence of leakage in the environment.

[0111] Figure 3 This is a schematic diagram of the structure of a cable provided in an embodiment of this application.

[0112] The cable includes a signal transmission line 301, a humidity detection line 302, and a sheathing layer 303.

[0113] Among them, the wrapping layer 303 wraps the signal transmission line 301 and the humidity detection line 302.

[0114] Signal transmission line 301 is used to transmit communication signals sent or received by the first circuit board. Humidity detection line 302 is used to transmit humidity detection signals.

[0115] The humidity detection signal can be used by the first circuit board to determine the humidity detection result of the environment in which the cable is located (i.e., the environment inside the server).

[0116] After the server starts up, the signal transmission line 301 in the cable can transmit communication signals sent or received by the first circuit board. At the same time, the humidity detection line 302 in the cable can transmit humidity detection signals, and the first circuit board can determine the humidity detection result of the environment in which the cable is located based on the humidity detection signals.

[0117] In this embodiment, the resistance of the humidity detection line 302 is related to the humidity of the environment in which the cable is located. The signal voltage of the humidity detection signal is used by the first circuit board to determine the humidity detection result.

[0118] Since the resistance of the humidity detection line 302 is related to the humidity of the environment in which the cable is located, and the voltage across the humidity detection line 302 is related to its resistance, the voltage across the humidity detection line 302 is also related to the humidity of the environment in which the cable is located.

[0119] Furthermore, the humidity detection result determined by the first circuit board based on the signal voltage of the humidity detection line 302 is related to the humidity of the environment in which the cable is located. Understandably, the humidity detection result determined by the first circuit board in this way is relatively accurate.

[0120] In this embodiment, the resistance of the humidity detection line 302 is negatively correlated with the humidity of the environment in which the cable is located.

[0121] That is, the higher the humidity of the environment where the cable is located, the lower the resistance of the humidity detection line 302, and the smaller the voltage difference between the two ends of the humidity detection line 302.

[0122] In one possible implementation, the cable includes multiple signal transmission lines 301, and the distance from at least one signal transmission line 301 to the sheath 303 is greater than the distance from the humidity detection line 302 to the sheath 303.

[0123] In practical applications, the cable typically includes multiple signal transmission lines 301 for transmitting communication signals sent or received by the first circuit board.

[0124] Understandably, due to the material of the cable sheath 303, condensation is highly likely to occur in it. Consequently, the resistance of the humidity detection line 302, which is wrapped by the sheath 303, will change due to condensation. Furthermore, the signal voltage of the humidity detection signal transmitted by the humidity detection line 302 will be affected by the condensation. The first circuit board can determine the humidity detection result of the environment in which the cable is located based on the signal voltage of the humidity detection signal.

[0125] It is also understandable that when condensation / leakage occurs in the environment where the cable is located, the closer the humidity detection line 302 is to the sheathing layer 303, the more the resistance of the humidity detection line 302 is related to the humidity of the environment where the cable is located. In this way, the humidity detection result determined by the first circuit board based on the humidity detection signal transmitted by the humidity detection line 302 is more accurate.

[0126] Therefore, in this embodiment of the application, when the cable includes multiple signal transmission lines 301, the distance from at least one signal transmission line 301 to the sheath 303 can be defined as greater than the distance from the humidity detection line 302 to the sheath 303.

[0127] In another possible implementation, the humidity detection line 302 is in contact with the wrapping layer 303, and / or there is a gap between the humidity detection line 302 and the wrapping layer 303.

[0128] Understandably, when condensation or leakage occurs in the environment where the cable is located, the resistance of the humidity detection line 302 within the sheath 303 will be affected by the condensation or leakage. Therefore, whether the humidity detection line 302 is in contact with the sheath 303 or there is a gap between them, the first circuit board can determine the humidity detection result based on the humidity detection signal transmitted by the humidity detection line 302.

[0129] In another possible implementation, the humidity detection line 302 is wound around the signal detection line.

[0130] Understandably, within the sheathing layer 303, the larger the contact area between the humidity detection line 302 and the sheathing layer 303, the greater the influence of condensation / leakage on the humidity detection line 302 from the environment where the cable is located. Furthermore, the more accurate the humidity detection signal transmitted by the humidity detection line 302. Compared to other setups, when the humidity detection line 302 is wrapped with the signal detection line, the contact area between the humidity detection line 302 and the sheathing layer 303 is larger. Moreover, the more turns the humidity detection line 302 is wrapped with the signal detection line, the larger the contact area between the humidity detection line 302 and the sheathing layer 303. Thus, the humidity detection result determined by the first circuit board based on the humidity detection signal is more accurate.

[0131] In one possible implementation, the humidity detection line 302 includes at least one set of first detection lines and second detection lines. A first end of the first detection line is connected to a first detection terminal of a first circuit board, a first end of the second detection line is connected to a second detection terminal of the first circuit board, and a second end of the first detection line is connected to a second end of the second detection line. The first circuit board is used to determine the humidity detection result based on the voltage difference between the humidity detection signal at the first and second detection terminals.

[0132] In practical applications, the humidity detection line 302 includes at least one set of first detection lines and second detection lines. A first end of the first detection line is used to connect to a first detection terminal of the first circuit board, a first end of the second detection line is used to connect to a second detection terminal of the first circuit board, and a second end of the first detection line is used to connect to a second end of the second detection line.

[0133] like Figure 1 As shown, the first and second humidity detection lines, together with the first circuit board, form a loop. This allows the first circuit board to detect the voltage difference between the first and second detection lines, meaning it can determine the humidity detection result based on the voltage difference between the first and second detection ends.

[0134] The humidity detection method according to embodiments of this application is described below.

[0135] This humidity detection method can be applied to, for example... Figure 1 or Figure 2 The first circuit board in the server shown.

[0136] like Figure 1 or Figure 2 As shown, the server also includes cables. The cables include signal transmission lines and humidity detection lines wrapped in a sheath.

[0137] Figure 4This is a schematic flowchart illustrating a humidity detection method according to an exemplary embodiment. Exemplarily, the humidity detection method may include the following steps S401-S402.

[0138] S401: Acquire the humidity detection signal transmitted in the humidity detection line.

[0139] In this embodiment, the server further includes cables, which include signal transmission lines and humidity detection lines wrapped in a sheathing layer. The first circuit board can acquire the humidity detection signal transmitted in the humidity detection line. Thus, when the first circuit board determines the humidity detection result of the server's internal environment, it can determine the humidity detection result within the server based on the humidity detection signal.

[0140] It is understandable that servers typically require cabling to transmit communication signals via signal transmission lines within the cabling. However, in this embodiment, a humidity detection line is integrated into the cabling, enabling the first circuit board to acquire the humidity detection signal transmitted through the humidity detection line and determine the humidity detection result of the cable environment based on the humidity detection signal.

[0141] In this way, this application does not require the deployment of humidity sensors or condensation sensors, and can directly determine the humidity detection results within the server based on the signal processing capabilities of the first circuit board.

[0142] S402: Determine the humidity detection result of the cable environment based on the humidity detection signal.

[0143] In this embodiment, the first circuit board can determine the humidity detection result of the cable environment based on the humidity detection signal.

[0144] The resistance of the humidity detection cable is related to the humidity of the environment in which the cable is located. That is, the higher the humidity of the environment, the lower the resistance of the humidity detection cable, and the lower the signal voltage of the humidity detection signal.

[0145] Therefore, when the first circuit board determines the humidity detection result of the cable environment based on the humidity detection signal, the first circuit board can determine the humidity detection result based on the signal voltage of the humidity detection signal.

[0146] In this embodiment, the humidity detection line includes a first detection line and a second detection line. The first end of the first detection line is connected to a first detection terminal of a first circuit board, the first end of the second detection line is connected to a second detection terminal of the first circuit board, and the second ends of the first and second detection lines are connected via the second circuit board.

[0147] In this way, the first detection line, the second detection line, and the first circuit board together form a loop. The first circuit board can determine the humidity detection result based on the voltage difference between the first and second detection terminals of the humidity detection signal. That is, when the first circuit board determines the humidity detection result based on the signal voltage of the humidity detection signal, it can also determine the humidity detection result based on the voltage difference between the first and second detection terminals of the humidity detection signal.

[0148] In one feasible approach, if the voltage difference is greater than or equal to a voltage threshold, the humidity detection result is determined to indicate that the humidity of the environment where the cable is located is normal. If the voltage difference is less than the voltage threshold, the humidity detection result is determined to indicate that the humidity of the environment where the cable is located is abnormal.

[0149] Abnormal humidity includes the presence of condensation in the environment and / or leakage in the environment.

[0150] Correspondingly, normal humidity includes the absence of condensation and leakage in the environment.

[0151] This humidity detection method can be applied to, for example... Figure 1 or Figure 2 The first circuit board in the server shown. (The text is incomplete and likely refers to a separate section.) Figure 1 , Figure 2 Taking this as an example, the humidity detection method will be introduced by way of example.

[0152] Example 1, this humidity detection method is applied to, for example... Figure 1 The first circuit board shown is a first circuit board. The first circuit board includes two detection terminals, wherein the first detection terminal of the first circuit board is connected to the first end of the first detection line, and the second detection terminal of the first circuit board is connected to the first end of the second detection line.

[0153] The first circuit board can acquire the humidity detection signal from the humidity detection lines (including the first detection line and the second detection line) and determine the voltage difference (i.e., the signal voltage of the humidity detection signal) between the first detection terminal and the second detection terminal on the first circuit board. If the voltage difference is greater than or equal to a voltage threshold, the first circuit board can determine that the humidity of the environment where the cable is located is normal. If the voltage difference is less than the voltage threshold, the first circuit board can determine that the humidity of the environment where the cable is located is abnormal.

[0154] Example 2, this humidity detection method is applied to, for example... Figure 2The first circuit board shown includes four detection terminals. Specifically, the first detection terminal of the first circuit board is connected to the first end of the first detection line in the first cable; the second detection terminal of the first circuit board is connected to the first end of the second detection line in the first cable; the third detection terminal of the first circuit board is connected to the first end of the third detection line in the second cable; and the fourth detection terminal of the first circuit board is connected to the first end of the fourth detection line in the second cable.

[0155] The first circuit board can acquire the first humidity detection signal from the humidity detection line in the first cable and determine the first voltage difference between the first detection end and the second detection end of the first humidity detection signal on the first circuit board.

[0156] The first circuit board can also acquire the second humidity detection signal from the humidity detection line in the second cable, and determine the second voltage difference between the second humidity detection signal and the third and fourth detection terminals on the first circuit board.

[0157] The first circuit board can determine the difference between the first voltage difference and the second voltage difference. If the difference between the first voltage difference and the second voltage difference is greater than or equal to a preset difference, it indicates that the first humidity detection signal and the second humidity detection signal are inaccurate and unreliable. The humidity detection result of the environment where the cable is located cannot be determined based on the first humidity detection signal and the second humidity detection signal at this time.

[0158] If the difference between the first voltage difference and the second voltage difference is less than the preset difference, it indicates that the first humidity detection signal and the second humidity detection signal are accurate and reliable.

[0159] The first circuit board can determine the humidity detection result of the environment where the cable is located based on the first voltage difference and / or the second voltage difference. That is, if the first voltage difference is greater than or equal to the voltage threshold and the second voltage difference is greater than or equal to the voltage threshold, the humidity detection result is determined to be that the ambient humidity inside the server is normal; if the first voltage difference is less than the voltage threshold and / or the second voltage difference is less than the voltage threshold, the humidity detection result is determined to be that the ambient humidity inside the server is abnormal; abnormal humidity includes the presence of condensation in the environment and / or the presence of leakage in the environment.
