Description
Technical Field
[0001] The present invention belongs to the technical field of server chassis deformation detection, and particularly relates to a method and system for detecting server chassis deformation. Background Art
[0002] During the operation of a computer server, the stability and integrity of the server chassis are crucial for the performance and reliability of the entire system. However, due to various factors such as transportation, installation, and temperature changes, the server chassis may deform, which may lead to problems such as damage to internal components, loose connections, or short circuits in the circuit. Moreover, servers are generally located in computer rooms, and when in use, people are in the office and have no idea about the situation of the server at all. Whether it is the maintenance personnel for repair or movement, it is very likely to cause bumps and deformations. Also, since the best heat dissipation effect of the server can be achieved only when the chassis is in a closed space, if the chassis deforms, it may cause the chassis cover to not close tightly, which will greatly affect the heat dissipation performance and the service life of the server. Therefore, detecting the deformation of the chassis in a timely and accurate manner has become an important technical challenge.
[0003] Traditional methods for detecting server chassis deformation mainly include using devices such as sensors, strain gauges, or pressure sensors. However, these methods usually require sensors to be installed outside the chassis, and complex wiring and installation work are needed. At the same time, they are easily affected by the external environment, and there are certain limitations in detection accuracy and reliability.
[0004] Therefore, how to improve the existing methods for detecting server chassis deformation, avoid complex wiring and installation work, and improve the accuracy and reliability of the detection results is a technical problem that urgently needs to be solved at present. Summary of the Invention
[0005] The purpose of the present invention is to provide a method and system for detecting server chassis deformation to solve the technical problems.

The matrix circuit film covers the inner wall of the server chassis, forming a thin film on the inner wall of the server chassis. A number of thin-film on-off switches are installed at each matrix point of the matrix circuit film. The main control chip is the control core of the detection system, connected to the thin-film on-off switches on the matrix circuit film, used to receive and process the changes in the switch states. The main control chip analyzes and judges whether the server chassis is deformed according to the received switch signals, and transmits the analysis and judgment result information to the baseboard management controller. The baseboard management controller is set on the main board of the server, responsible for monitoring the running state of the server. When the main control chip transmits the server chassis deformation information obtained by analysis to the baseboard management controller, the baseboard management controller executes according to the preset strategy.
[0008] Preferably, the inner wall of the server chassis is divided into different deformation regions, and different matrix point spacing densities of the matrix circuit film are set on different deformation regions. For the deformation regions with high deformation requirements on the inner wall of the server chassis, the matrix point spacing density of the matrix circuit film set is greater than that of the matrix circuit film in the deformation regions with low deformation requirements on the inner wall of the server chassis.

[0015] S3: Integrate thin-film on-off switches on each matrix point of the matrix circuit film, and lay the matrix circuit film with integrated thin-film on-off switches on each matrix point on the inner wall of the server chassis to be tested;
[0016] S4: Establish a connection between the matrix circuit film with integrated thin-film on-off switches and the main control chip. When the server starts, the matrix circuit film is automatically powered on, and the main control chip will obtain the on-off information of all thin-film on-off switches on the matrix circuit film in real time;
[0017] S5: The main control chip converts the analog signals of all obtained thin-film on-off switch on-off information into digital signals, and the main control chip analyzes the digital signals to determine whether the server chassis is deformed. If so, execute step S6;
[0018] S6: Transmit the information about the deformation of the server chassis and the position of the deformation to the baseboard management controller. The baseboard management controller sends a control signal to the warning module. When the warning module receives the control signal, it issues a warning signal to the server administrator.
[0019] Preferably, the specific process of converting analog signals to digital signals in step S5 is as follows:
[0020] S51: Extract analog signals from the analog signals of all thin-film on-off switch on-off information at a specified time interval, and convert the continuous analog signals into discrete analog signals;
[0021] S52: Divide the continuous range of the discrete analog signals into multiple levels, each level corresponding to a digital value, and create a mapping relationship table between the analog signals and the digital values according to each level corresponding to a digital value;
[0022] S53: Obtain the discrete analog signals and call the mapping relationship table, convert the discrete analog signals into corresponding digital values, and encode the corresponding digital values into binary codes.
[0023] Preferably, the specific process of step S6 is as follows:
[0024] S61: Transmit the information about the deformation of the server chassis and the position of the deformation to the baseboard management controller. The baseboard management controller receives the digital signal of the deformation of the server chassis, and extracts the deformation degree information and the deformation position information from the digital signal;
[0025] S62: After the baseboard management controller obtains the deformation degree information and the deformation position information, it determines whether a warning is needed. If so, execute step S63. If not, transmit the deformation degree information and the deformation position information to the management terminal for storage;
[0026] S63: The baseboard management controller sends a control signal to the warning module. When the warning module receives the control signal, it sends a warning signal to the server administrator.
[0027] The beneficial effects of the present invention include:
[0028] The detection method and system for server chassis deformation provided by the present invention include a matrix circuit film, a thin-film on-off switch, a main control chip, and a baseboard management controller. The matrix circuit film covers the inner wall of the server chassis, forming a thin film on the inner wall of the server chassis. There are several thin-film on-off switches, which are installed at each matrix point of the matrix circuit film. The main control chip is the control core of the detection system, connected to the thin-film on-off switches on the matrix circuit film, and is used to receive and process the change of the switch state. The main control chip analyzes and judges whether the server chassis is deformed according to the received switch signal, and transmits the analysis and judgment result information to the baseboard management controller. The baseboard management controller is set on the main board of the server and is responsible for monitoring the running state of the server. The above detection system avoids the wiring and installation of sensors, and improves the detection accuracy and reliability at the same time.
[0029] First, by setting a matrix circuit film, a thin-film on-off switch, a main control chip, and a baseboard management controller, the detection system eliminates the need to set sensors outside the chassis, reduces the wiring and installation work, and improves the overall aesthetics and reliability of the system.
[0030] Second, by dividing the inner wall of the server chassis into different deformation regions and setting different matrix point spacing densities of the matrix circuit film on different deformation regions, for the deformation regions with high requirements for the deformation of the inner wall of the server chassis, the matrix point spacing density of the matrix circuit film set is greater than that of the matrix circuit film in the deformation regions with low requirements for the deformation of the inner wall of the server chassis. A high matrix point spacing density is set for the region with low deformation tolerance, and the deformation detection accuracy of this region is increased by increasing the matrix point density. A low matrix point spacing density is set for the region with high deformation tolerance, and the cost is reduced without affecting the detection requirements by reducing the matrix point density.
[0031] Third, by extracting the analog signal of the on-off information of all thin-film on-off switches at a specified time interval, converting the continuous analog signal into a discrete analog signal; dividing the continuous range of the discrete analog signal into multiple levels, each level corresponding to a digital value, and creating a mapping relationship table between the analog signal and the digital value according to each level corresponding to a digital value; obtaining the discrete analog signal and calling the mapping relationship table, converting the discrete analog signal into the corresponding digital value, and encoding the corresponding digital value into a binary code. The data processing complexity is reduced, the data processing efficiency is improved, and the deformation detection response is enhanced.
[0032] Finally, by transmitting the deformation of the server chassis and the position information of the deformation to the baseboard management controller, the deformation degree information and the deformation position information are extracted; after the baseboard management controller obtains the deformation degree information and the deformation position information, it judges whether early warning is needed, and the baseboard management controller sends a control signal to the early warning module. When the early warning module receives the control signal, it sends an early warning signal to the server administrator, improving the response flexibility and scalability of the system.

[0051] Based on Embodiment 1 or Embodiment 2, the specific process of converting analog signals to digital signals in step S5 is as follows:
[0052] S51: Extract the analog signals of all the on-off information of the thin-film on-off switches at a specified time interval, and convert the continuous analog signals into discrete analog signals for digital processing. Sample values of the analog signals are extracted through a specific sampling frequency to ensure that the interval between each sample value is fixed.
[0053] S52: Divide the continuous range of the discrete analog signals into multiple levels, each level corresponding to a digital value, and create a mapping relationship table between the analog signals and the digital values according to each level corresponding to a digital value; Divide the continuous range of the analog signals into multiple levels, each level corresponding to a digital value, and then classify the sample values into the nearest level.

By dividing the inner wall of the server chassis into different deformation regions and setting different matrix point spacing densities of the matrix circuit film on different deformation regions, for the deformation regions with high requirements for the inner wall deformation of the server chassis, the matrix point spacing density of the set matrix circuit film is greater than that of the matrix circuit film in the deformation regions with low requirements for the inner wall deformation of the server chassis. A high matrix point spacing density is set for the region with low deformation tolerance, and the deformation detection accuracy of this region is increased by increasing the matrix point density. A low matrix point spacing density is set for the region with high deformation tolerance, and the cost is reduced without affecting the detection requirements by reducing the matrix point density.
