The MCU is connected with the mainboard of the computing device through an inter-integrated circuit (I2C) bus, wherein the I2C bus includes a serial data (SDA) pin and a serial clock line (SCL) pin, and the MCU can obtain information in the mainboard through the SDA pin and the SCL pin. The MCU is used to send a read-write instruction to the RFID read-write chip through the SDO pin, and the RFID read-write chip sends component information read from the RFID tag unit in response to the read-write instruction to the MCU through the SDI pin; the MCU is used to select the RFID read-write chip through the CS pin, and the MCU is used to send a clock signal to the RFID read-write chip through the SCLK pin. The RF antenna is connected with the mainboard and the RFID tag unit through a radio frequency signal, and the RFID read-write chip obtains component information from the RFID tag unit through a video signal of the RF antenna.

[0049] In one embodiment, the RFID tag unit is used to obtain to-be-queried component information from an external device with radio frequency function, the RFID tag unit stores a component information list of the computing device, and in a case where the to-be-queried component information is obtained, the RFID tag unit can send an interrupt signal to the control unit MCU through the GPO pin and the GPIO pin, the MCU reads the to-be-queried component information and the component information list stored in the RFID tag unit through the RFID read-write chip in a case where the interrupt signal is obtained, compares the to-be-queried component information with each component information recorded in the component information list, and determines whether the to-be-queried component exists in the computing device according to a comparison result.

[0050] Further, the MCU can send a reading instruction to the RFID read-write chip through the SDO interface when the interrupt signal is acquired. The RFID read-write chip can acquire the component information list and the component information to be queried from the RFID tag unit through the RF antenna after acquiring the reading instruction, and send the acquired component information list and the component information to be queried to the MCU through the SDI interface.

[0051] The MCU can determine the first prompt or the second prompt according to the comparison result when determining whether the component to be queried exists in the computing device according to the comparison result. The first prompt is determined according to the comparison result that the component to be queried exists in the computing device, and the second prompt is determined according to the comparison result that the component to be queried does not exist in the computing device.

[0052] When the first prompt and the second prompt are LED light prompts, the MCU can output the first prompt or the second prompt through the LED light according to the comparison result when determining whether the component to be queried exists in the computing device according to the comparison result. The first prompt and the second prompt are different. In some embodiments, the color corresponding to the first prompt is different from the color corresponding to the second prompt. In other embodiments, the color corresponding to the first prompt is different from the color corresponding to the second prompt, and the display time of the color corresponding to the first prompt and the display time of the color corresponding to the second prompt can be the same or different.

[0053] In an embodiment, the color corresponding to the first prompt is different from the color corresponding to the second prompt. If the MCU finds the component to be queried according to the comparison result, the MCU can control the LED light to light up according to the color corresponding to the first prompt through the GPIO pin. If the MCU does not find the component to be queried according to the comparison result, the MCU can control the LED light to light up according to the color corresponding to the second prompt through the GPIO pin.

[0054] For example, the LED light is a double-color light. If the MCU finds the component to be queried according to the comparison result, the MCU can control the LED light to light up according to the green color corresponding to the first prompt, that is, the LED light displays a green light. If the MCU does not find the component to be queried according to the comparison result, the MCU can control the LED light to light up according to the yellow color corresponding to the second prompt, that is, the LED light displays a yellow light.

[0055] In another embodiment, the first prompt corresponds to a color, and the second prompt corresponds to no color. If the MCU finds the component to be queried according to the comparison result, the MCU can control the LED light to light up according to the color corresponding to the first prompt through the GPIO pin. If the MCU does not find the component to be queried according to the comparison result, the MCU can control the LED light to not light up according to the second prompt through the GPIO pin.

[0056] For example, the LED lamp is a single-color lamp. If the MCU finds the component to be queried according to the comparison result, the MCU can control the LED lamp to light up in green according to the first prompt, that is, the LED lamp displays a green light. If the MCU does not find the component to be queried according to the comparison result, the MCU can control the LED lamp to not light up according to the second prompt.

[0057] In another embodiment, the color and display time corresponding to the first prompt are different from the color and display time corresponding to the second prompt. If the MCU finds the component to be queried according to the comparison result, the MCU can control the LED lamp to light up according to the color and display time corresponding to the first prompt. If the MCU does not find the component to be queried according to the comparison result, the MCU can control the LED lamp to light up according to the color and display time corresponding to the second prompt.

[0058] For example, if the MCU finds the component to be queried according to the comparison result, the MCU can control the LED lamp to light up in green for 60 seconds according to the first prompt, that is, the LED lamp displays a green light for 60 seconds. If the MCU does not find the component to be queried according to the comparison result, the MCU can control the LED lamp to light up in yellow for 60 seconds according to the second prompt, that is, the LED lamp displays a yellow light for 60 seconds.

[0059] In another embodiment, the RFID tag unit is configured to obtain the component information to be queried from an external device with a radio frequency function. The MCU can obtain the component information list of the computing device from the BMC on the mainboard of the computing device. When the RFID tag unit obtains the component information to be queried, the RFID tag unit can send an interrupt signal to the MCU through the GPO pin and the GPIO pin. When the MCU obtains the interrupt signal, the MCU reads the component information to be queried stored in the RFID tag unit through the RFID read-write chip, and compares the component information to be queried with each component information recorded in the component information list. According to the comparison result, it is determined whether the component to be queried exists in the computing device. Further, the MCU can obtain the component information list of the computing device from the BMC on the mainboard of the computing device through the SDA pin and the SCL pin of the mainboard.

[0060] In an embodiment, when the MCU obtains the component information list of the computing device from the BMC of the computing device, the MCU can read the component information list in the BMC through the read-write unit. The MCU can read the component information list in the BMC according to a preset period and store it in the receiving stack of the MCU.

[0061] The control unit compares the to-be-inquired component with each component information in the component information list, which helps to improve the efficiency of finding the specific component (i.e., the to-be-inquired component) in the machine room. The query result is displayed by the prompt unit (e.g., an LED lamp), and the result feedback can be quickly obtained, which is more intuitive.

[0062] The application also provides a cabinet server, which comprises at least one tag unit and a plurality of computing devices, each of which is connected with the at least one tag unit, wherein one tag unit can be connected with a plurality of computing devices. Figure 2 For example, Figure 2 is a structural schematic diagram of a cabinet server provided by an embodiment of the application, as shown in Figure 2 , one RFID tag serving as a tag unit is connected with two computing devices, i.e., the RFID tag is connected with a computing device 1 and the RFID tag is connected with a computing device 2. One tag unit can be connected with a plurality of computing devices, and the plurality of computing devices can be quickly searched for a to-be-inquired component simultaneously by using one tag unit, which reduces the number of manual operations and improves the efficiency of searching for the to-be-inquired component in the machine room.

[0063] Optionally, a plurality of tag units can be connected with a plurality of computing devices. Figure 3 For example, Figure 3 is another structural schematic diagram of a cabinet server provided by an embodiment of the application, as shown in Figure 3 , two RFID tags serving as tag units are connected with two computing devices, i.e., one RFID tag is connected with a computing device 1 and the other RFID tag is connected with a computing device 2. A plurality of tag units can be connected with a plurality of computing devices, which helps to further quickly search for a to-be-inquired component simultaneously by using a plurality of computing devices and a plurality of tag units, which reduces the number of manual operations and improves the efficiency of searching for the to-be-inquired component in the machine room.

[0064] The component query method provided by the embodiments of the application will be described schematically below with reference to the accompanying Figure 4 , the accompanying Figure 5 .

[0065] For details, please refer to Figure 4 , Figure 4 is a flowchart of a component query interaction method provided by an embodiment of the application.

[0072] S407: The MCU controls the LED lamp to light green, so that the user determines that the to-be-inquired component information exists in the computing device according to the green light of the LED lamp.

[0073] S408: The MCU controls the LED lamp to light yellow, so that the user determines that the to-be-inquired component information does not exist in the computing device according to the yellow light of the LED lamp.

[0074] When the RFID tag reads the to-be-inquired component information stored in the external device with RFID read-write function, the RFID tag sends an interrupt signal to the MCU, triggers the MCU interrupt, reads the to-be-inquired component information in the RFID tag through the RFID read-write unit, and compares the to-be-inquired component information acquired from the RFID tag with the component information list. If the to-be-inquired component information is in the component information list in the comparison result, the LED lamp can be controlled to light green, so that the user determines that the to-be-inquired component information exists in the computing device according to the green light of the LED lamp. If the to-be-inquired component information is not in the component information list in the comparison result, the LED lamp can be controlled to light yellow, so that the user determines that the to-be-inquired component information does not exist in the computing device according to the yellow light of the LED lamp. In this way, it is helpful to quickly inquire whether the to-be-inquired component exists in the computing device.
