Description

Technical Field

[0001] This utility model relates to a health management system, specifically an intelligent health management system based on a VPX architecture computing platform. Background Technology

[0002] VPX is an open architecture standard for high-performance embedded computing. It is designed for harsh environments, supports high bandwidth, and has high reliability and modular scalability. Therefore, it is widely used in scenarios that require real-time processing, high-density computing, and robustness.

[0003] Traditional VPX architecture computing platforms prioritize system functionality and performance during design, neglecting the health of individual modules and the overall platform. This leads to the following problems during long-term use:

[0004] 1) The VPX architecture computing platform adopts a modular design and supports multiple functional modules, such as processor, I / O, storage, and signal processing modules. Each module supports high power density (above 200W), and each module generates a lot of heat. However, it is impossible to obtain the temperature value of the core components of the module in real time. If the cooling fan of the entire platform is running at maximum speed, it will generate a lot of buzzing noise. If a multi-speed fixed-speed cooling fan is used, there will be abnormal noise from the cooling fan frequently changing speeds during operation. If a conventional fixed-speed cooling fan is used, it cannot achieve the expected heat dissipation effect in high-temperature environments or high-power operation.

[0005] 2) During the debugging of the VPX architecture computing platform, because the health status of different modules cannot be presented in the form of data, the fault location time is long when problems occur;

[0006] 3) If a malfunction occurs after the VPX architecture computing platform is delivered, it cannot be managed remotely and technical personnel need to be on-site to resolve the issue, resulting in high after-sales costs. Utility Model Content

[0020] Furthermore, the power module, computing processing module, auxiliary processing module, Ethernet switching module, data storage module, and timing and positioning module each have a built-in power chip with an EN enable pin and a Power Good feedback pin.

[0040] The present invention will be further described below with reference to the accompanying drawings and specific embodiments.

[0041] Reference Figure 1 This utility model discloses an intelligent health management system based on a VPX architecture computing platform for health monitoring of the VPX architecture computing platform. The VPX architecture computing platform includes a chassis, a motherboard installed inside the chassis, and VPX modules installed on the motherboard. To dissipate heat from the VPX modules, a cooling fan 07 is installed on the chassis. Generally, a VPX module includes a power module 01, a computing processing module 02, an auxiliary processing module 03, an Ethernet switching module 04, a data storage module 05, and a timing and positioning module 06. The six modules are interconnected through onboard circuits on the motherboard. The power module 01 supplies power to the other five VPX modules and the cooling fan 07. The power module 01 adopts the VITA62 standard design, while the computing processing module 02, auxiliary processing module 03, Ethernet switching module 04, data storage module 05, and timing and positioning module 06 adopt the VITA46 standard design.

[0042] The intelligent health management system based on the VPX architecture computing platform in this embodiment includes a system management controller (SMC), a baseboard management controller (BMC), and a power supply module. There are six baseboard controllers 2, distributed across a power supply module 01, a computing processing module 02, an auxiliary processing module 03, an Ethernet switching module 04, a data storage module 05, and a timing and positioning module 06, respectively. Each of the six baseboard controllers 2 is electrically connected to its corresponding power supply module 01, computing processing module 02, auxiliary processing module 03, Ethernet switching module 04, data storage module 05, and timing and positioning module 06. The management controller 1 is located on the data storage module 05. The management controller 1 is interconnected with the six baseboard controllers 2 via an IPMB (Intelligent Platform Management Bus). To enable data communication, each baseboard controller 2 is electrically connected to the IPMB bus via two I2C connections. The management controller 1 is connected to the control terminal of the cooling fan 07 and is also connected to the user terminal via Ethernet. This allows the fan speed to be adjusted in real time based on the heat generated by each VPX module, and the user can perform health monitoring of the entire VPX architecture computing platform via Ethernet.

[0043] The management controller 1 is placed on the data storage module 05 because the management controller 1 needs to receive various data transmitted from each baseboard controller 2. Its power and heat generation are relatively large. After thermal simulation of the chassis, the data storage module 05 with the least heat generation and relatively good heat dissipation conditions is selected to ensure the normal operation of the management controller 1.

[0044] The intelligent health management system has an independent power supply, that is, it uses an independent power supply module to supply power to the baseboard controller 2 and the management controller 1. Its power supply voltage is 3.3V, instead of drawing power from the power module 01 of the VPX architecture computing platform, to prevent the entire intelligent health management system from stopping working if the power module 01 fails.

[0045] The substrate controller 2 includes a first controller, a voltage detection unit, a current detection unit, and a temperature detection unit;

[0046] The voltage detection unit includes a voltage divider resistor installed on the power input terminals of the power module 01, the calculation and processing module 02, the auxiliary processing module 03, the Ethernet switching module 04, the data storage module 05, or the timing and positioning module 06. The voltage divider resistor is electrically connected to the first controller and performs signal conditioning on the voltage to be collected from the power input terminal. That is, the voltage collected from the power input terminal is adjusted to the voltage range acceptable to the first controller through the voltage divider resistor. In order to isolate and transform impedance, a voltage follower is set between the voltage divider resistor and the first controller to improve load capacity and acquisition accuracy.

[0047] The current detection unit includes a current sensing resistor and a current detection chip on the power input terminals of the power supply module 01, the calculation and processing module 02, the auxiliary processing module 03, the Ethernet switching module 04, the data storage module 05, or the timing and positioning module 06. There are two current detection chips, which are respectively connected to the two ends of the current sensing resistor. The current detection chip is electrically connected to the first controller. The current sensing resistor is in the milliohm range. The current detection chip can realize overcurrent alarm while calculating the current value.

[0048] The temperature detection unit includes an external temperature sensor or a built-in temperature sensor. The external temperature sensor is installed on the power module 01, computing processing module 02, auxiliary processing module 03, Ethernet switching module 04, data storage module 05 or timing and positioning module 06. The built-in temperature sensor is the built-in temperature sensor of the power module 01, computing processing module 02, auxiliary processing module 03, Ethernet switching module 04, data storage module 05 or timing and positioning module 06. The external temperature sensor or the built-in temperature sensor is electrically connected to the first controller.

[0049] To achieve power-on / off detection and remote control of the power supply module 01, computing processing module 02, auxiliary processing module 03, Ethernet switching module 04, and timing and positioning module 06, each module has a built-in power chip with an EN enable pin and a Power Good feedback pin. Each module's power chip manages the voltage supplied by the power supply module 01, as the power supply module 01 can only provide one voltage, such as the standard 24V. However, the components within each module may require voltages such as 5V or 12V. Therefore, the power chip needs to convert the voltage supplied by the power supply module 01 before delivering it to the various components. Controlling the power chip controls the power-on / off of the entire module. The EN enable pin and Power Good feedback pin of each power chip are electrically connected to the GPIO port of the first controller of the corresponding baseboard controller 2. The first controller's GPIO sends signals to change the EN enable pin and Power Good feedback pin. The power-on / power-off control is achieved by monitoring the level of the Good feedback pin. By detecting the level of the EN enable pin and the Power Good feedback pin, it can also be determined whether the entire module is powered on.

[0050] The management controller 1 includes a second controller and a PHY chip. The second controller of the management controller 1 is connected to all the first controllers via the IPMB bus, which allows the data detected by the first controllers to be aggregated and sent to the user terminal for remote viewing by staff. To facilitate connection with the user terminal via Ethernet, a PHY chip is provided, which is electrically connected to the second controller. The PHY chip is used to connect with the user terminal via Ethernet, specifically via Gigabit Ethernet and according to the IPMI (Intelligent Platform Management Interface) 2.0 standard protocol. The Intelligent Platform Management Interface (IPMI) is a standard applied to the design of server management systems. IPMI achieves automatic detection and recovery of the platform through specific hardware and firmware, providing detection, event logging, and recovery functions independent of the CPU, BIOS, and operating system. In this embodiment, both the first controller and the second controller are MCU controllers.

[0051] The GA0-GA4 and GAP pins of the VPX connectors for power module 01, computing processing module 02, auxiliary processing module 03, Ethernet switching module 04, data storage module 05, and timing and positioning module 06 should be pulled up / down or left floating according to the table below to form a correspondence table of module ID, module name, physical address, hardware address, and IPMB address:

[0052]

[0053] After obtaining the temperature data of each VPX module, the management controller 1 will output a PWM wave through the second controller to regulate the cooling fan 07. This adopts a threshold-based regulation strategy, which changes the duty cycle of the PWM signal of the cooling fan 07 as the temperature changes, thereby controlling its speed to achieve the design requirement of near constant temperature.

[0054] First, we introduce ΔT. j Concept:

[0055] ΔT j =T jmin -T j

[0056] ΔT j =T j -T jmin

[0057] In the above formula, T jmax T represents the maximum allowable junction temperature of the core components of each VPX module under normal operating conditions. jmin T represents the minimum junction temperature allowed under normal operating conditions of the core device. j Let ΔT be the instantaneous junction temperature during the operation of the core device. j This indicates the margin between the maximum or minimum allowable junction temperature distance of the core component.

[0058] Because there are many VPX modules, the junction temperature ranges of the core components in different VPX modules are not entirely the same. When operating in a sub-zero temperature environment, the highest junction temperature value among the minimum junction temperatures of the core components of all VPX modules is compared. The temperature value detected by the substrate controller 2 is recorded as T, and T is approximately estimated. j =T+3℃. When ΔT j When the temperature is ≤10℃, the cooling fan 07 stops working, that is, the speed is 0.

[0059] When operating in an environment above zero degrees Celsius, the lowest junction temperature among the maximum junction temperatures of the core devices in all VPX modules is compared. The temperature value detected by the substrate controller 2 is denoted as T, and T is approximately estimated. j =T+5℃. ΔT j =T jmax -T j Substitute into the following formula for calculation:

[0060]

[0061] When ΔT j When the temperature is >40℃, the PWM of the cooling fan 07 is maintained at 30% (approximately 3500rpm); when the temperature is ≥40℃, ΔT jWhen the temperature is >15℃, the cooling fan speed 07 follows the PWM = -kΔT j The +C formula is used for control, where k is the slope and C is a constant; when ΔT j When the temperature is ≤15℃, the cooling fan 07 is controlled to operate at 100% PWM full speed to regulate the temperature. Slope k and constant C are referenced. Figure 2 and Figure 3 Adjustments and controls are to be made.

[0062] By controlling the cooling fan 07 through the management controller 1, the environmental adaptability of the VPX architecture computing platform can be effectively compensated for the shortcomings of the temperature range of individual VPX modules in the platform, thereby improving the overall environmental adaptability of the machine.

[0063] The embodiments described above are merely descriptions of specific implementations of this utility model and are not intended to limit the scope of this utility model. Various modifications and improvements made to the technical solutions of this utility model by those skilled in the art without departing from the spirit of this utility model should fall within the protection scope defined by the claims of this utility model.
