Description

Technical Field

[0001] This invention belongs to the field of computer processors, and specifically relates to a power supply dual redundancy and processor component operation status monitoring circuit. Background Technology

[0002] With the rapid development of information technology, computer equipment has permeated many key fields such as industrial control, IoT terminals, data center servers, remote area monitoring equipment, and vehicle electronic systems, becoming a core infrastructure supporting social production and life. The core working mechanism of such computer equipment relies on the coordinated operation of computer components and power supply components: the computer components are centered on the central processing unit (CPU), which, through the deployment of software programs with specific functions, realizes predetermined application scenarios such as data processing, instruction execution, and business logic processing; the power supply components provide a stable and continuous power supply for the entire device, which is the energy foundation for ensuring the normal operation of computer components (especially the CPU).

[0003] In recent years, with the continuous upgrading of the demand for device functionality diversity, computing speed, and data processing capacity in various application fields, as well as the popularization of high-performance applications such as artificial intelligence, big data analysis, and high-definition video processing, the performance requirements of devices for CPUs have shown an exponential growth. Specifically, this is manifested in the continuous increase in the number of CPU cores, the continuous increase in the operating frequency, and the widespread application of heterogeneous computing architectures. This directly leads to a sharp increase in CPU power consumption. Correspondingly, in order to match the high-performance operation requirements of CPUs, power supply components not only need to provide greater output power, but also need to have higher conversion efficiency and faster dynamic response speed to adapt to the instantaneous power consumption fluctuations of CPUs, while reducing their own energy loss.

[0004] However, as the performance and power consumption of CPUs and power supply components improve simultaneously, the complexity of the equipment system also increases significantly. On the one hand, the high integration design of CPUs (such as the significant increase in transistor density under advanced process technology) makes them significantly more sensitive to voltage stability and heat dissipation conditions, and relatively reduces their anti-interference ability. On the other hand, in order to improve efficiency, high-power power supply components often adopt high-frequency switching topologies, which increases the complexity of circuit design, and the heat dissipation pressure brought by high-power operation accelerates the aging speed of components such as capacitors, inductors, and power transistors inside the power supply. In addition, the overall modular integration of the equipment increases the coupling between computer components and power supply components, and a local fault in a single component can easily spread to the entire system through signal transmission and power supply circuits.

[0005] The combination of these factors directly leads to a continuous decline in the reliability of the entire computer equipment system, a significant reduction in the mean time between failures (MTBF), and poses numerous severe challenges to the long-term stable operation of the equipment. The likelihood of power supply failure increases, and if the power supply fails, the entire system will crash. If the CPU malfunctions, the software cannot run properly, and the entire system will malfunction. In some unattended scenarios, when the above-mentioned faults occur, remote connection is impossible, and the status of the equipment cannot be determined. The rising failure rate has led to an increase in the manpower, time, and economic costs of inspection and maintenance.

[0006] More importantly, in existing technologies, the reliability design of processors and power supply components is mostly optimized independently. For example, the stability of a single component is improved by improving the processor heat dissipation structure and improving the quality of power supply components. However, the synergistic effect and chain reaction of failures between the two are not fully considered, and there is a lack of integrated solutions to solve the problems of reliability degradation, insufficient fault warning and difficulty in remote operation and maintenance. Summary of the Invention

[0007] The purpose of this invention is to overcome the problem of high failure rate and difficult maintenance of computer systems, and to propose a power supply dual redundancy and processor component operation status monitoring circuit.

[0008] To achieve the above objectives, the present invention adopts the following technical solution: In a first aspect, the present invention provides a power supply dual redundancy and processor component operation status monitoring circuit, including a redundant power supply, a safety control unit, a redundant current sharing circuit and a redundant circuit. The redundant power supply includes at least two power supply components. The first output terminal of each power supply component is connected to the input terminal of the redundant current sharing circuit, and the second output terminal of the power supply component is connected to the input terminal of the redundant circuit. The output of the redundant current sharing circuit is connected to the power supply of the processor component; The output of the redundant circuit is connected to the power supply terminal of the safety control unit; The safety control unit communicates with the processor component and is connected to the fault indication component. The redundant current sharing circuit evenly distributes the output current of each power supply component. When any one of the at least two power supply components fails, the remaining power supply components of the at least two power supply components continue to supply power to the processor component. In the event of a failure of any one of the at least two power supply components, the safety control unit is continuously powered by the remaining power supply components of the at least two power supply components. The safety control unit interacts with the processor component via a communication connection; if no heartbeat feedback is received within a preset time, the processor component is triggered to reset; if there is still no heartbeat feedback after the reset, the control fault indication component outputs a fault signal. The safety control unit uses a safety microcontroller (MCU).

[0009] Furthermore, the processor component is a central processing unit (CPU) component or a graphics processing unit (GPU) component.

[0010] Furthermore, the power supply is configured with two components, and the redundant current sharing circuit is a dual-power supply current sharing controller with built-in MOSFET ideal diodes.

[0011] Furthermore, the dual-power current sharing controller uses the LTC4370 chip.

[0012] Furthermore, the communication connection between the safety control unit and the processor component is a serial communication connection.

[0013] Furthermore, the redundant current sharing circuit isolates reverse current from through current during power component startup or failure.

[0014] Furthermore, the fault indication component includes an indicator light, which the safety control unit controls to flash at a preset frequency when it does not receive heartbeat feedback from the processor component.

[0015] In a second aspect, the present invention provides a method of using a dual-redundant power supply and processor component operation status monitoring circuit, comprising the following steps: Start at least two power supply components in the redundant power supply, each power supply component outputs current to the redundant current sharing circuit through the first output terminal and outputs current to the redundant circuit through the second output terminal; The redundant current sharing circuit distributes the input current of each power supply component equally and then outputs current to the power supply terminal of the processor component to continuously power the processor component. The redundant circuit directly outputs current to the power supply terminal of the safety control unit, providing continuous power to the safety control unit; The safety control unit establishes a heartbeat interaction with the processor component through a communication connection to obtain the heartbeat feedback signal of the processor component in real time. If the safety control unit does not receive a heartbeat feedback signal from the processor component within a preset time period, the processor component will be triggered to perform a reset operation. If the safety control unit still does not receive a heartbeat feedback signal after the processor component is reset, the safety control unit controls the fault indication component to output a fault signal. When any one of the at least two power supply components fails, the remaining power supply components continue to supply power to the processor component through a redundant current sharing circuit, and continue to supply power to the safety control unit through a redundant circuit, thus maintaining the normal operation of the processor component and the safety control unit.

[0016] Furthermore, if the safety control unit does not receive heartbeat feedback from the processor component within a preset time period, it first triggers the processor component to perform a reset operation; if it still does not receive heartbeat feedback within a preset time period after the reset, it controls the fault indication component to output a fault signal and sends a fault alarm message to the remote terminal.

[0017] Furthermore, the redundant current sharing circuit synchronously isolates reverse current and through current during the startup or failure of each power supply component.

[0018] Compared with the prior art, the present invention has the following beneficial technical effects: This invention proposes a dual-redundant power supply and processor component operation status monitoring circuit. It adds a power supply component to the traditional processor operating circuit and a safety component between the computer component and the power supply component, thereby improving the overall system's safety and reliability, increasing the mean time between failures (MTBF), and incurring only a small cost increase. This effectively solves practical problems such as high failure rates and difficult maintenance in computer systems. The power supply component has a high failure rate; therefore, two power supplies are used for redundancy backup. Redundancy employs hot backup and average current mode. Both power supplies use the same specifications to power the computer component, with each power supply handling half the current, reducing the power supply load and lowering the power consumption of a single power supply while reducing the failure rate. When one power supply fails, the other can continue to supply power without affecting the normal operation of the computer component; only timely replacement of the spare power supply is required. Computer components have a high failure rate, typically occurring during system startup or unexpected errors and freezes during software operation. To address these issues, a safety microcontroller unit (MCU) with a lower failure rate is used to protect the processor component with a higher failure rate. The safety MCU's main task is to monitor the power output status and interact with the processor component. If a power supply component fails, it sends an alarm signal requesting immediate replacement. If the computer component cannot return the interaction command normally, it indicates that the computer has crashed or failed to start normally. In this case, the safety microcontroller can choose to restart the CPU, shut down the power and power it back on, or perform other operations to try to clear some common faults. If the interaction still fails, it promptly sends a fault command, remotely alarms, and notifies after-sales service. Attached Figure Description

It should be understood that such data can be interchanged where appropriate so that the embodiments of the invention described herein can be implemented in orders other than those illustrated or described herein.

[0030] Example 1 See Figure 1A dual-redundancy power supply and processor component operation status monitoring circuit includes a redundant power supply, a safety control unit, a redundant current sharing circuit, and a redundant circuit. The safety control unit uses a safety microcontroller (MCU). The processor component is a central processing unit (CPU) or a graphics processing unit (GPU). The redundant power supply includes at least two power supply components. The first output terminal of each power supply component is connected to the input terminal of the redundant current sharing circuit, and the second output terminal of each power supply component is connected to the input terminal of the redundant circuit. The output terminal of the redundant current sharing circuit is connected to the power supply terminal of the processor component. The output terminal of the redundant circuit is connected to the power supply terminal of the safety control unit. Two power supply components are provided. The redundant current sharing circuit is a dual-power supply current sharing controller with built-in MOSFET ideal diodes. The dual-power supply current sharing controller uses an LTC4370 chip. The safety control unit is communicatively connected to the processor component, and the communication connection between the safety control unit and the processor component is a serial communication connection. The safety control unit is connected to the fault indication component; the redundant current sharing circuit evenly distributes the output current of each power supply component, and when any one of the at least two power supply components fails, the remaining power supply components continuously supply power to the processor component; the redundant current sharing circuit isolates reverse current and through current during the power supply component startup or failure; the redundant circuit continuously supplies power to the safety control unit when any one of the at least two power supply components fails; the safety control unit interacts with the processor component via a communication connection; if no heartbeat feedback is received within a preset time, the processor component is triggered to reset; if there is still no heartbeat feedback after the reset, the fault indication component is controlled to output a fault signal. The fault indication component includes an indicator light, and the safety control unit controls the indicator light to flash at a preset frequency when no heartbeat feedback is received from the processor component.

[0031] This embodiment ensures uninterrupted power supply, with dual power supply components and redundant current sharing circuits providing double backup. In the event of a power supply failure, the remaining components seamlessly compensate. Combined with the current sharing function of the LTC4370 chip, it achieves both even current distribution to prevent single-power-supply overload and eliminates power interruptions, providing uninterrupted power to core components such as the CPU / GPU. It is suitable for high-reliability scenarios such as industrial control and servers. Hardware damage protection is upgraded; the redundant current sharing circuit incorporates MOSFET ideal diodes, effectively isolating reverse current and through current during power startup or fault switching, preventing current surges that could damage the processor and power supply components, significantly reducing hardware failure rates and extending the overall lifespan of the equipment. Fault response is precise and efficient; the safety MCU interacts with the processor via serial communication, automatically triggering a reset if no feedback is received after a preset time. If the reset fails, a fault indication is immediately activated. The indicator lights flash at a preset frequency, making the fault status clearly visible and allowing for quick problem location without complex testing. The monitoring and power supply closed-loop system is reliable, with redundant circuitry providing dual backup power to the safety control unit. This ensures the monitoring module itself is unaffected by power failures, achieving a complete closed-loop system of "power supply assurance - status monitoring - fault handling," preventing the escalation of faults due to monitoring failures. It balances adaptability and practicality, being compatible with different processor components such as CPUs and GPUs. The serial communication method is highly versatile, allowing for integration into various electronic systems without significant modifications. It meets the high security requirements of high-end equipment while offering low-cost deployment, balancing performance and cost-effectiveness.

[0032] Example 2 See Figure 1 A method for using a dual-redundant power supply and processor component operation status monitoring circuit includes the following steps: At least two power supply components in the redundant power supply are activated. Each power supply component outputs current to the redundant current sharing circuit through its first output terminal and to the redundant circuit through its second output terminal. The redundant current sharing circuit distributes the current input to each power supply component equally and then outputs current to the power supply terminal of the processor component, providing continuous power to the processor component. The redundant circuit directly outputs current to the power supply terminal of the safety control unit, providing continuous power to the safety control unit. The safety control unit establishes a heartbeat interaction with the processor component through a communication connection and obtains the heartbeat feedback signal of the processor component in real time. If the safety control unit does not obtain the heartbeat feedback signal of the processor component within a preset time, it triggers the processor component to perform a reset operation. If the safety control unit still does not obtain the heartbeat feedback signal after the processor component is reset, it controls the fault indication component to output a fault signal. When any of the at least two power supply components fails, the remaining power supply components continue to supply power to the processor component through the redundant current sharing circuit and to the safety control unit through the redundant circuit, maintaining the normal operation of the processor component and the safety control unit.

[0033] If the safety control unit does not receive heartbeat feedback from the processor component within a preset time period, it first triggers the processor component to perform a reset operation; if no heartbeat feedback is received within the preset time period after the reset, it controls the fault indication component to output a fault signal and sends a fault alarm message to the remote terminal.

[0034] The redundant current sharing circuit synchronously isolates reverse current and through current during the startup or failure of each power supply component.

[0035] This embodiment provides uninterrupted power supply, ensuring stable operation of core equipment. The dual-redundant power supply design utilizes at least two power components operating in parallel. If any component fails, the remaining components can seamlessly continue power supply through redundant current sharing circuits and redundant circuits, completely avoiding system downtime caused by single-point power failures. The redundant current sharing circuits simultaneously isolate reverse and through currents, preventing damage to power components from current imbalances and avoiding abnormal currents affecting the processor and safety control unit. This provides continuous, stable, and clean power input to critical equipment, making it suitable for scenarios with extremely high power supply continuity requirements, such as industrial control and medical equipment. Proactive fault warning reduces maintenance costs and losses. The safety control unit monitors the processor status in real time via heartbeat interaction. If no feedback is received within a preset time, a reset operation is triggered to quickly resolve temporary faults such as program freezes, restoring operation without manual intervention. If the reset fails, fault prompts and remote alarms are immediately activated, allowing maintenance personnel to immediately pinpoint the fault location (power supply or processor) and prevent the fault from escalating. This "automatic repair, tiered alarm" mode significantly shortens fault diagnosis time, reduces losses such as production stoppages and data loss caused by system downtime, and lowers manual inspection costs. Dual safety protection enhances the system's resilience. The safety control unit is independently powered by redundant circuitry, separated from the processor power supply link, ensuring that even if the processor power supply is abnormal, the monitoring function can still operate normally, avoiding the superposition of "monitoring failure" and "equipment failure." Simultaneously, the isolation design for reverse current and through current not only protects power components and extends their lifespan but also prevents abnormal current from damaging the core chip, forming a triple guarantee of "power supply redundancy, current protection, and status monitoring." This significantly improves the system's anti-interference and fault resistance capabilities in complex environments, ensuring business continuity and data security.

[0036] Example 3 See Figure 1 A dual-redundancy power supply and processor component operation status monitoring circuit, see [link / reference]. Figure 2 and 3The redundant current sharing circuit uses the ADI LTC4370 chip, known as a dual-supply diode "combining" current balance controller. It is primarily used in redundant power supplies, high-availability systems, servers, and telecommunications and network infrastructure applications. It shares the load between two power supplies, eliminating the need for additional active control of the input power supply. It does not require a shared bus, isolates reverse current, has no follow-current during startup or faults, operates on the 0V to 18V high-voltage side, enables the input MOSFET to be in the ON state, and operates in dual-channel ideal diode mode. See also... Figure 3 The LTC4370 is a dual-supply current sharing controller with integrated MOSFET ideal diodes. These diodes isolate reverse and shoot-through currents during startup and fault conditions. Their forward voltage can be regulated to share load current between power supplies. Unlike other current sharing methods, this device does not require a shared bus or trimming pin on the power supply. The maximum MOSFET voltage drop can be set using a resistor. Fast gate turn-on reduces load voltage drop during power switching. Fast turn-off minimizes reverse current transients in the event of an input power supply failure or short circuit. The controller operates from a 2.9V to 18V supply range. For lower rail voltages, an external power supply needs to be connected to the VCC pin. The enable input can be used to turn off the MOSFETs and place the controller in a low-current state. The status output indicates whether the MOSFETs are on or off. The load sharing function can be disabled to turn the LTC4370 into a dual-channel ideal diode controller.

[0037] Safety microcontroller redundant circuit design, such as Figure 4 As shown in the diagram, the communication connection between the security microcontroller and the processor component is illustrated in the figure below. Figure 5 In this embodiment, taking the CPU as an example, the security microcontroller communicates with the main CPU via a serial port. The host computer sends a heartbeat data transmission protocol to the microcontroller. If the security microcontroller does not receive the heartbeat packet sent by the host computer within 5 minutes, the security microcontroller will reset the host computer. If the heartbeat protocol is still not received after the reset, the microcontroller will control an external indicator light, which will flash red continuously to notify the staff.

[0038] The circuit diagram of the external fault alarm indicator is as follows: Figure 6 If the microcontroller does not receive a heartbeat packet from the CPU or GPU within 5 minutes, the microcontroller controls the MOG transistor to make the external indicator light flash red.
