[0021] The above and other technical contents, features and functions of the present invention are described in detail below with reference to the attached Figure 1 To Attachment Figure 3 The detailed description of the embodiments will clearly show that the structural contents mentioned in the following embodiments are all based on the drawings in the specification.

[0022] Various exemplary embodiments of the present utility model will be described below with reference to the accompanying drawings.

[0023] like Figure 1 As shown, the command signal processing circuit based on the Shenwei 831EEB server includes:

[0024] The command receiving module is used to receive the command signal sent remotely from the user terminal and perform matching processing on the command signal;

[0025] an amplification and conditioning module, used to amplify and condition the output signal of the instruction receiving module to adapt to subsequent processing; and

[0026] The Shenwei 831EEB server is used to receive the command signal output by the amplification and conditioning module, and process and execute the command signal.

[0027] In the above, the command receiving module includes a signal receiver E1, an impedance matching network and an isolator. The signal receiver E1 is used to receive a remote command signal, and then send the command signal to the impedance matching network for impedance compatibility to adjust the transmission characteristics of the command signal, and finally send it to the isolator for isolated output of the command signal to suppress noise and signal interference from entering the subsequent circuit.

[0028] Specifically, Figure 2 As shown, the impedance matching network includes a capacitor C1, one end of the capacitor C1 is connected to the signal receiver E1, the other end of the capacitor C1 is connected to the resistors R1, R2 and one end of the inductor L1, the other end of the resistor R1 is grounded, and the other ends of the resistor R2 and the inductor L2 are connected to the isolator and grounded through the capacitor C2.

[0029] In the above, the impedance matching network composed of RLC elements is used to make the command signal received by the signal receiver E1 impedance compatible, reduce the reflection and distortion of useful signals, and thus greatly improve the energy efficiency of receiving the command signal. The isolator further isolates the command signal after impedance matching to prevent noise and interference from entering the subsequent circuit. The isolator uses the voltage follower AR1 of model LM741. LM741 has high input impedance and low output impedance, which helps to maintain the quality of the command signal and provides good signal isolation to ensure that the command signal remains in the best state during the reception process.

[0030] Since the received command signal is relatively weak, an amplification and conditioning module is set to amplify and condition the output signal of the command receiving module. Figure 3 As shown, the amplification and conditioning module includes a signal enhancement circuit and a stabilization adjustment circuit. The signal enhancement circuit includes an op amp AR2 and a transistor VT1. The inverting input terminal of the op amp AR2 is connected to resistor R4 and one end of resistor R5. The other end of resistor R4 is connected to resistor R3, one end of capacitor C3 and the cathode of Zener diode DZ1. The other end of resistor R5 and the anode of Zener diode DZ1 are grounded. The other end of resistor R3 is connected to the output end of the isolator. The other end of capacitor C3 is connected to the emitter of transistor VT1. The in-phase input terminal of the op amp AR2 is grounded through capacitor C4. The output end of the op amp AR2 is connected to the base of transistor VT1. The collector of transistor VT1 is connected to the command signal input terminal of Shenwei 831EEB server through the stabilization adjustment circuit.

[0031] Furthermore, the stabilization regulation circuit includes a MOS tube Q1, the drain of the MOS tube Q1 is connected to one end of the resistor R6 and the collector of the transistor VT1, the gate of the MOS tube Q1 is connected to the other end of the resistor R6 and is grounded through the capacitor C5, and the source of the MOS tube Q1 is connected to the command signal input end of the Shenwei 831EEB server and is grounded through the parallel resistor R7 and the capacitor C6.

[0032] In the processing of the amplification and conditioning module, the signal enhancement circuit first uses the voltage stabilizing diode DZ1 to stabilize the amplitude of the output signal of the op amp AR1, and then sends it to the op amp AR2 for enhancement processing. In order to improve the signal amplification efficiency, a transistor VT1 is set at the output end of the op amp AR2 for follow-up amplification, so that the signal enhancement circuit has a high gain effect, and can quickly amplify the small amplitude command signal to a level sufficient to be recognized by the server. At the same time, capacitor C3 plays a role in signal compensation in the op amp feedback loop to improve the frequency response of the op amp, reduce phase distortion, and ensure the integrity of the command signal. The stabilization and regulation circuit uses MOS tube Q1 as a regulating tube to further stabilize the enhanced command signal. Since MOS tube Q1 can provide a fast dynamic response and uses capacitor C5 to filter its gate conduction signal, it can suppress transient interference and ensure that the command signal has high quality when transmitted to the server, thereby improving the reliability of the entire system.

[0033] The Shenwei 831EEB server includes a SW831 processor, a storage controller and an I / O interface. The SW831 processor receives the command signal output by the amplification and conditioning module through the I / O interface, and writes the data generated during the processing into the storage controller. The SW831 processor executes the indicated operation according to the instruction content.

[0034] Among them, the SW831 processor is a 64-bit RISC architecture processor, adopts a multi-core structure and system-on-chip technology, and integrates 8 Core3 structure processor cores on a single chip, with a maximum operating frequency of 2.5GHz and a peak computing speed of 512.0GFlops@2.0GHz. The multi-core design and high main frequency of the SW831 processor significantly improve the computing power. The storage controller is connected to the SW831 processor through a dual-channel DDR4 interface. The dual-channel DDR4 interface doubles the memory bandwidth, improves the data access speed, and helps alleviate memory access conflicts. The I / O interface supports the PCI-E 4.0 standard. Its high bandwidth and low latency characteristics enable the server to connect to high-performance devices, which provides the server with extensive scalability and flexibility, enabling it to adapt to various high-performance computing needs.

[0035] In summary, the utility model first receives and processes the remote command signal through the command receiving module, and uses the impedance matching network and isolator to reduce signal distortion and interference, so that the weak command signal can be effectively received; then the amplification and conditioning module is used to accurately amplify and stably process the command signal, effectively improving the transmission quality of the command signal to ensure that the Shenwei 831EEB server can effectively identify and execute the corresponding instructions, thereby improving the anti-interference ability and reliability of the entire system. In addition, the Shenwei 831EEB server can provide stable and efficient services, meeting the strict requirements of cloud computing, big data analysis, and the Internet of Things for high-performance computing platforms.

[0036] The above is a further detailed description of the utility model in combination with a specific implementation method, and it cannot be determined that the specific implementation of the utility model is limited to this; for technical personnel in the field of the utility model and related technical fields, based on the technical solution of the utility model, the expansion and replacement of operating methods and data should all fall within the protection scope of the utility model.
