Description

Technical Field

[0001] The utility model belongs to the technical field of power transmission and transformation of electric power systems, and specifically relates to an intelligent edge computing device for operation, maintenance and inspection of substations and converter stations. Background Art

[0002] With the rapid development of artificial intelligence technology, artificial intelligence training in the cloud and artificial intelligence reasoning on the edge have been widely used, and machine vision and chatGPT large language models have begun to be implemented in various industries. In order to improve the operation and maintenance efficiency of substations and converter stations, power grid companies conduct multi-type perception collection including visible light, infrared, and voiceprint on a large number of primary equipment in the station, and then call artificial intelligence reasoning on the edge side of the station to identify defects, and even artificial intelligence fault mechanism analysis based on big data, which requires the use of artificial intelligence chips with hundreds of TOPS INT8 computing power.

[0003] At present, the mainstream high-computing power artificial intelligence reasoning solution is to install a GPU graphics card or artificial intelligence card with a PCIe interface in the server, and the server CPU calls the AI ​​computing power in the PCIe card to complete AI reasoning analysis. The essence of this PCIe card solution is that the server CPU connects multiple AI chips through the PCIe bus, multiple PCIe slots are set on the server motherboard, and GPU graphics cards or cards with AI chips are installed in the PCIe slots. It is a centralized structure solution. Although it can provide very powerful AI computing power, the system coupling is high and there is a problem of hardware resource competition. In addition, the structural form of this server PCIe card also has the problem of inconvenient operation and maintenance. For example, once a GPU graphics card or artificial intelligence PCIe card in the server fails, the server needs to be shut down as a whole and the cover opened for replacement, which is not only troublesome to operate, but also causes all services running on the server to be interrupted. In addition, the CPU and AI of the computing power card need to run a large number of calculations, which release a large amount of heat during the operation. In the existing technology, the heat generated by the computing power card is mostly cooled by setting rotating devices such as fans on the computing power card. Mechanical wear, aging, and failure are prone to occur during operation, and frequent replacement is required, which greatly affects the reliability of the equipment. Utility Model Content

[0048] As mentioned in the background technology, the current mainstream artificial intelligence solution is to install a GPU graphics card or artificial intelligence card with a PCIe interface in the server, and the server CPU calls the AI ​​computing power in the PCIe card to complete the reasoning analysis.

[0050] The specific embodiments of the present invention will be described in detail below with reference to the accompanying drawings.

The guide rails are arranged in parallel to form a plurality of parallel slots, and the slots are parallel to the left and right sides of the chassis. The computing power card 10 and the power card 11 are inserted into the slots along the direction of the guide rails and fixed. The health indicator is arranged in front of the chassis 14 and connected to the bus board 12 through a cable. The health indicator is used to display the working status of the intelligent edge computing device.

[0055] A plurality of mutually independent computing power cards 10 and a plurality of mutually independent power supply cards 11 may be arranged inside a chassis 14. The computing power cards provide scalable artificial intelligence edge computing capabilities, and the power supply cards are used to provide working power to the inside of the chassis.

[0056] In a preferred but non-limiting embodiment of the present invention, two power supply cards 11 with independent structures are inserted as standard in a chassis 14. The two power supply cards 11 are connected to the bus board 12 through connector terminals to achieve parallel connection, forming a device power supply redundancy structure connected to two external power supplies to achieve power supply redundancy.

[0057] Further, see Figure 3, the computing power card 10 includes a computing power card panel, a heating device, a heat sink and an external communication interface. The external communication interface is set on the computing power card panel. The heat sink is connected to the heating device by surface contact. The heating device includes the computing power card CPU 101 and the computing power card AI 102; the computing power card CPU 101 is connected to the computing power card AI 102 and the external communication interface respectively. The computing power card CPU is used to run the operating system and perform general computing, storage and communication functions; the computing power card CPU and the computing power card AI work together to complete edge computing including artificial intelligence large model reasoning; the heat sink is used to radiate the heat of each device of the computing power card into the air; the external communication interface is used for external data interaction, and the types of external communication interfaces include but are not limited to Ethernet electrical port, Ethernet optical port, RS-485 and / or USB, etc.

[0058] In a preferred but non-limiting embodiment of the present invention, the power card CPU 101 refers to a multi-core processor. In order to support the operation of the power card CPU 101, memory (such as DDR) and hard disk (such as SSD) hardware cooperation is also required. The power card AI 102 can be an independent AI chip or an independent AI module, such as an AI module with a standard COMe interface, and the AI ​​module includes a high-power AI chip and a large-capacity memory; the power card AI 102 is connected to the power card CPU 101 through a PCIe bus.

[0059] The power card 11 includes: a power card panel and a power module. The power module is arranged inside the power card panel. An external power input interface, a power switch and a power indicator light (not shown in the figure) are arranged on the power card panel. The power switch is connected in series between the external power input interface and the power module. The power indicator light is connected to the power module. The power module is connected to the bus board 12 through the connector terminal; the power module is used to convert the external input power into the internal working power of the intelligent edge computing device; the power switch is used to connect or disconnect the external input power; the power indicator light is used to display the working status of the power card 11.

[0060] In a preferred but non-limiting embodiment of the present invention, the external input power supply supports multiple types of AC 110 / 220V and DC 110 / 220 / 48V, and the internal working power supply of the intelligent edge computing device is DC 24V. The power card 11 converts the AC 220V external input power supply through the power module to AC / DC, and converts it into a low-voltage 24V DC power supply, which is distributed to the computing card 11 and the fan card 13 through the connector terminal through the bus board 12. In addition, the power card 11 can also transmit its own operating status through the connector terminal. When the power card 11 itself fails, it will change the IO level form, transmit the power failure signal to the bus board 12, and finally summarize it to the CPU of the bus board 12. Once a power card 11 fails, the CPU of the bus board 12 will set an alarm sign and control the health indicator of the chassis to yellow. There is a boat-shaped power switch on the panel of the power card 11, which is connected in series between the external power input and the power module to control the external input power to be turned on or off. The panel of the power card 11 also has a power indicator light for indicating the working status. A green LED indicates that the power output is normal, and a yellow LED indicates an internal alarm of the power supply.

[0061] The bus board 12 is perpendicular to the guide rail direction and is fixed by screws on the rear side of the mounting frame. There is a set distance between the top, bottom and back of the mounting frame. The bus board 12 includes: multiple connector terminals and a bus board CPU 121, wherein the computing power card 10, the power card 11 and the fan card 13 are plugged into the bus board CPU through the connector terminals; the connector terminals are used to transmit DC working power and communication bus signals, and provide working power transmission and communication bus interconnection functions. The bus board CPU 121 is used to monitor the operating status of the computing power card 10 and the fan card 13, and to control the speed of the fan 131 and the health indicator of the intelligent edge computing device.

[0062] In a preferred but non-limiting embodiment of the utility model, a plurality of connector terminals are arranged on the bus board 12, which are respectively connected to each computing power card 10, power card 11, and fan card 13. These connector terminals provide DC working power on the one hand, and on the other hand, the connector terminals are interconnected to form a communication bus to provide data interactive communication functions; the bus board CPU 121 is used to monitor the operation status of the computing power card and control the fan speed, and output the health status of the device. The bus board CPU 121 communicates with each computing power card through the bus, and the bus board CPU 121 communicates with each fan on the fan card through the general IO pin, outputs speed instructions to the fan, and receives the actual speed of the fan.

[0063] The fan card 13 is fixed to the rear back of the mounting frame by screws, and the fan card is set higher than the bus board 12; the fan card 13 includes multiple independent fans 131 and fan card connector terminals, and the fan 131 is plugged into the fan card 13 through the fan connector terminal. The fan is a hot-swappable structure with power on, and the fan card is used for forced air cooling to achieve active heat dissipation of the intelligent edge computing device.

[0064] In a preferred but non-restrictive embodiment of the utility model, the fan card 13 is connected to the bus board 12 via a connector terminal. On the one hand, the fan card 13 obtains a DC working power supply from the bus board 12 to drive the fan to rotate. On the other hand, the fan 131 sends a speed control signal and a speed status signal to the bus board CPU 121. The bus board CPU 121 can output square wave signals with different duty cycles to control the speed of each fan, and can also receive the actual speed value output by the fan to determine whether the fan is working normally. If the actual speed value of the fan deviates greatly from the control value, the bus board CPU 121 can determine that the fan is faulty, and then control the health status indicator light of the chassis to remind the user to repair and eliminate the fault.

[0065] The computing power card 10, the power card 11 and the fan 131 all support hot swapping, allowing the device to replace a faulty board or fan online without powering off.

[0066] In a preferred but non-limiting embodiment of the utility model, the computing power card 10 communicates with the external system through the Gigabit Ethernet electrical port, receives visible light, infrared and other sensor data collected by fixed cameras and drones in substations and converter stations, and then performs artificial intelligence reasoning and analysis. Finally, the results of the artificial intelligence reasoning and analysis are output to the external system through the external communication interface for display or archiving.

[0067] The types of communication bus signals include, but are not limited to, CAN bus, RS-485 bus and / or Ethernet bus.

[0068] In a preferred but non-limiting embodiment of the present invention, the communication bus type is a CAN bus. Each computing power card 10 acts as a CAN node and communicates with the bus board CPU 121. The CAN bus can transmit the status information of each computing power card (such as the temperature value of the computing power card and the health mark). After receiving the status information of each computing power card 10, the bus board CPU 121 can dynamically adjust the fan speed of the fan card 13 according to the temperature of the computing power card 10, thereby achieving the effect of heat dissipation and energy saving. In addition, the bus board CPU 121 obtains the status information of all computing power cards 10 and power cards 11, forms the operation status information of the device level, and then controls the health indicator of the chassis 14.

[0069] In a preferred but non-limiting embodiment of the present invention, the health indicator light of the chassis 14 is a three-color LED light, green indicates normal operation, yellow indicates an alarm, and red indicates a serious fault.

[0070] In a preferred but non-limiting embodiment of the utility model, the computing power card 10 and the power card 11 are connected to the bus board through the onboard connector terminals, and the connector terminals can transmit direct current or digital signals; the power card outputs direct current power to the bus board, and also outputs a "power normal / PWR_OK" digital signal (1 or 0) to the bus board. When the power card works normally, PWR_OK is 1, and when it is abnormal, PWR_OK is 0. The bus board CPU 121 obtains the working status of the power card by reading the PWR_OK signal on the bus board. When two power cards are configured, the bus board CPU 121 reads the PWR1_OK and PWR2_OK signals of the bus board to determine which power card is abnormal.

[0071] The chassis 1 includes a mounting frame and at least one health indicator light, such as Figure 2 As shown. The mounting frame of the chassis is used to install and fix the computing power card, power card, bus board and fan card. The chassis provides multiple guide rails. Each slot can be inserted with a computing power card or a power card. The number of guide rails depends on the size of the chassis. The computing power card 10 and the power card 11 are inserted into the chassis through the guide rails. When inserted in place, the computing power card 10 and the power card 11 can be connected to the bus board 12 of the chassis through the connector terminals. In a preferred but non-limiting embodiment of the utility model, the chassis 1 is a standard width of 19 inches, which is suitable for installation in a screen cabinet. The status indicator light of the chassis 1 is arranged on the panel directly in front of the chassis to display the operating status of the device, such as operation or alarm. The chassis 1 is equipped with 2 LED lights, namely the operation light and the alarm light, which are convenient for operation and maintenance personnel to patrol and check, in line with the operating habits of substations and converter stations.

[0072] In a preferred but non-limiting embodiment of the utility model, each fan in the computing power card 10, the power card 11, and the fan card 13 uses a connector with staggered pins to ensure that grounding and local power are established before other connections are made, so as to achieve hot plugging without power outage, minimize the impact on the operation of the business system, and improve the availability of the system.

[0073] An air inlet is arranged at the bottom of the front of the chassis 1, and cold air enters the chassis through the air inlet. Figure 2 As shown, the heat sink that contacts the computing power card is turned into hot air; an air outlet is set on the top of the rear of the chassis, and each fan of the fan card 13 exhausts air outward, bringing the heat inside the chassis to the external environment of the chassis, thereby realizing passive heat dissipation of heat-generating components such as the computing power card CPU and the computing power card AI.

[0074] Through the above example embodiments, the power card has its own processor and artificial intelligence chip, which can independently realize computing tasks such as artificial intelligence reasoning. The power card and power card both support hot swapping, and the faulty board can be replaced without power failure and business interruption, making operation and maintenance simple and convenient. In addition, the power card itself has no fan for passive heat dissipation and no fan rotating device, so the operation reliability is high. The fan can also be replaced independently, which is very convenient for operation and maintenance.

[0075] The utility model provides an intelligent edge computing device that can use a distributed, independent computing card structure to provide a scalable edge-side artificial intelligence computing solution. The business of each computing card is independent and does not affect each other, and advanced artificial intelligence applications targeting primary and secondary power equipment can be realized.

[0076] Each fan in the power card, power card and fan card supports hot swapping, and the faulty board can be replaced without power failure and business interruption, which makes operation and maintenance simple and convenient. In addition, the device is equipped with dual power supplies. Except for the fan card, the power card, power card and bus board inside the device do not have fan rotating devices, so the device has high operating reliability.

[0077] The utility model proposes an embedded solution for independent computing power card insertion. Each computing power card is configured with a processor and an artificial intelligence chip, and can independently complete artificial intelligence applications including large language model reasoning, realizing distributed artificial intelligence edge computing. The computing power card supports hot plugging, and the faulty board can be replaced without powering off the device, which is convenient for maintenance. The business of other computing power cards is not affected, achieving the effect of continuous operation.

[0078] Finally, it should be noted that the above embodiments are only used to illustrate the technical solution of the utility model rather than to limit it. Although the utility model is described in detail with reference to the above embodiments, ordinary technicians in the relevant field should understand that the specific implementation methods of the utility model can still be modified or replaced by equivalents, and any modifications or equivalent replacements that do not depart from the spirit and scope of the utility model should be included in the scope of protection of the claims of the utility model.
