Description

Technical Field

[0001] The present invention relates to the field of high-voltage inverter technology, and in particular to a fault diagnosis method, system, storage medium and terminal for a high-voltage inverter. Background Art

[0002] High-voltage inverters are used for high-voltage (several thousand volts to more than ten thousand volts) high-power motors and are often used in heavy-duty continuously working automation equipment such as power stations, mines, steel, and petrochemical industries. This type of large-scale continuously working automation equipment has very high requirements for the pre-diagnosis and alarm of its own faults.

[0003] In the existing technology, the main chip of the high-voltage inverter is mostly a two-chip structure consisting of DSP + FPGA. The DSP serves as the center of calculation and control, and the FPGA converts the DSP calculation results into the signals required by the power unit in real time to control the operation of the motor.

[0004] Regarding the above-mentioned related technologies, since they use a two-chip structure of DSP and FPGA, the DSP has a heavy workload, and since the fault information is sent to the display screen by the DSP, once the DSP chip fails or crashes, it will not be able to transmit the fault information, which will affect work efficiency and needs to be improved. Summary of the Invention

[0005] In order to improve work efficiency, the present invention provides a fault diagnosis method, system, storage medium and terminal for a high-voltage inverter.

[0006] In a first aspect, the present invention provides a fault diagnosis method for a high-voltage inverter, which adopts the following technical solution:

[0007] A fault diagnosis method for a high-voltage frequency converter, comprising:

[0008] Obtaining fault detection information of a preset controller circuit;

[0009] Match the faulty chip from the preset chip database according to the fault detection information;

[0010] Determine whether the faulty chip is consistent with the preset ARM chip;

[0011] If the faulty chip is inconsistent with the ARM chip, the ARM chip is controlled to output the preset chip fault information to the preset display terminal;

[0012] If the faulty chip is the same as the ARM chip, the preset DSP chip is controlled to output the chip fault information to the display terminal.

[0013] By adopting the above technical solution, the specific chip with the fault is known by understanding the consistency between the faulty chip and the ARM chip. When the faulty chip and the ARM chip are consistent, the chip fault information is output by controlling the ARM chip. This avoids the problem of being unable to transmit fault information when the ARM chip fails, thereby improving work efficiency.

[0014] Optionally, the fault detection information needs to be obtained using a preset fault detection method, which includes:

[0015] When performing fault detection on the ARM chip, the ARM chip is defined as the detection chip, the next chip after the detection chip is defined as the output chip, and the next chip after the output chip is defined as the receiving chip;

[0016] After a preset reference time, the data reception value of the output chip is obtained;

[0017] Calculating the difference between the data reception value and the preset reference reception value as the data difference value;

[0018] Determine whether the data difference value is consistent with the preset benchmark difference value;

[0019] If the data difference value is consistent with the reference difference value, the control output chip outputs a normal signal of the detection chip to the preset fault processing chip;

[0020] If the data difference value is inconsistent with the reference difference value, the control output chip outputs the detection chip fault information to the fault processing chip, and controls the output chip to output the sum of the reference receiving value and the preset fault correction value to the receiving chip.

[0021] By adopting the above technical solution, the consistency between the data difference value and the reference difference value is determined to determine whether the detection chip is faulty. When the detection chip is faulty, the output chip is controlled to output the fault information to the fault processing chip, thereby improving the processing speed when the chip fails.

[0022] Optionally, also include:

[0023] Obtain power information of the fault processing chip;

[0024] Determine whether the power information is less than the preset reference power information;

[0025] If and only if the power information is less than the reference power information, the ARM chip is controlled to output a low power signal to the display terminal;

[0026] When the ARM chip fails, the DSP chip is controlled to output a low power signal and ARM chip failure information to the display terminal;

[0027] When there is no fault in the ARM chip, the ARM chip is controlled to output a low power signal and DSP chip fault information to the display terminal.

[0028] By adopting the above technical solution, the power status of the fault processing chip is determined by understanding the relationship between power information and baseline power information. When the power of the fault processing chip is low, the control chip outputs a low-power signal to prompt personnel to replace the battery of the fault processing chip, thereby reducing the risk of storage failure caused by system power outages during storage.

[0029] Optionally, also include:

[0030] Obtaining operation image information of the display terminal;

[0031] Determining whether the operation image information contains a preset portrait feature;

[0032] If and only if the operation image information includes a portrait feature, determining the portrait distance based on the operation image information, the portrait feature, and a preset reference object;

[0033] When the portrait distance is less than a preset reference portrait distance, matching the display orientation from a preset posture adjustment library according to the portrait posture;

[0034] When the display orientation is inconsistent with a preset reference orientation, the display terminal is controlled to rotate to be consistent with the display orientation.

[0035] By employing the above technical solution, the operating status of the display terminal is determined by understanding whether the operational image information and the human portrait are included. If included, the display orientation is determined by understanding the distance and posture of the human portrait. Finally, the rotation status of the display terminal is determined by understanding the consistency between the display orientation and the reference orientation. When rotation is required, the display terminal is controlled to rotate to align with the display orientation, thereby facilitating operator operation of the display terminal.

[0036] Optionally, also include:

[0037] Determine the number of portraits based on the operating image information and portrait features;

[0038] Determining whether the number of portraits is greater than a preset reference number of portraits;

[0039] If the number of portraits is not greater than the number of reference portraits, the portrait pose is determined based on the operation image information and the portrait features;

[0040] If the number of portraits is greater than the number of reference portraits, the operator's features are matched from the preset portrait database based on the operation image information;

[0041] Determine the operator's posture based on the operation image information and the operator's characteristics;

[0042] Matching the main display orientation from the attitude adjustment library according to the operator's attitude;

[0043] When the main display orientation is inconsistent with the reference orientation, the display terminal is controlled to rotate to be consistent with the main display orientation.

[0044] By adopting the above technical solution, when the number of portraits is greater than the reference number of portraits, the operator's characteristics can be known by understanding the operation image information, and then the operator's posture can be matched. The main display direction can be known through the operator's posture, and the display terminal can be controlled to rotate to be consistent with the main display direction, so as to facilitate the operation of the display terminal by the operating staff.

[0045] Optionally, also include:

[0046] Get the status information of the detection chip;

[0047] Determine whether the status information is consistent with the preset fault information;

[0048] If and only if the status information is consistent with the fault information, obtain the screen operation area of the display terminal;

[0049] Determine the idle screen area based on the screen operation area and the preset terminal screen area;

[0050] Matching a display position from a preset display database according to the idle screen area;

[0051] Controls the preset prompt box to display the prompt content at the display position.

[0052] By adopting the above technical solution, the fault status of the detection chip can be determined by understanding the consistency between the status information and the fault information. When the detection chip fails, the idle screen area and the display position can be determined by understanding the screen operation area and the terminal screen area. Finally, the prompt box is controlled to display the prompt content at the display position, so that the staff can better view the prompt content.

[0053] Optionally, also include:

[0054] Acquire the infrared detection image of the display terminal;

[0055] Determine the blocked field of view area based on the infrared detection image, screen operation area, and terminal screen area;

[0056] Determine the remaining display area based on the blocked visual field area and the terminal screen area;

[0057] Determining whether the remaining display area is smaller than a preset reference display area;

[0058] If the remaining display area is not smaller than the reference display area, the prompt box is controlled to display the prompt content at the display position;

[0059] If the remaining display area is smaller than the reference display area, the area of the prompt box is matched from the display database according to the remaining display area and the display position is updated;

[0060] The control prompt box is adjusted to be consistent with the prompt box area, and the prompt content is displayed at the updated display position.

[0061] By adopting the above technical solution, the size of the prompt box is known by understanding the size relationship between the remaining display area and the reference display area. When the size of the prompt box needs to be reduced, the area of the prompt box is known by understanding the remaining display area, thereby reducing the size of the prompt box. As a result, the prompt box will not affect the staff's operation when providing a prompt, and at the same time, the staff can better view the prompt content.

[0062] In a second aspect, the present application provides a fault diagnosis system for a high-voltage inverter, which adopts the following technical solution:

[0063] A fault diagnosis system for a high-voltage frequency converter, comprising:

[0064] An acquisition module is used to obtain fault detection information, data reception value, power information, operation image information, status information, and screen operation area;

[0065] A memory for storing a program for any of the above-mentioned methods for diagnosing faults of high-voltage inverters;

[0066] The program in the processor memory can be loaded and executed by the processor to implement any of the above-mentioned high-voltage inverter fault diagnosis methods.

[0067] In a third aspect, the present application provides a computer storage medium capable of storing a corresponding program, which is characterized by being convenient for implementing a fault diagnosis method for a high-voltage inverter, and adopts the following technical solution:

[0068] A computer-readable storage medium stores a computer program that can be loaded by a processor and executed by any of the above-mentioned high-voltage inverter fault diagnosis methods.

[0069] In a fourth aspect, the present application provides a smart terminal, which adopts the following technical solution:

[0070] An intelligent terminal includes a memory and a processor. The memory stores a computer program that can be loaded by the processor and execute any one of the above-mentioned high-voltage inverter fault diagnosis methods.

[0071] By adopting the above technical solution, the specific chip with the fault is known by understanding the consistency between the faulty chip and the ARM chip. When the faulty chip and the ARM chip are consistent, the chip fault information is output by controlling the ARM chip. This avoids the problem of being unable to transmit fault information when the ARM chip fails, thereby improving work efficiency.

[0072] In summary, this application includes at least one of the following beneficial technical effects:

[0073] 1. By understanding the consistency between the faulty chip and the ARM chip, the specific chip with the fault can be determined. When the faulty chip and the ARM chip are consistent, the chip fault information can be output by controlling the ARM chip. This avoids the problem of being unable to transmit the fault information when the ARM chip fails, thereby improving work efficiency.

[0074] 2. When the number of portraits exceeds the reference number, the operator's characteristics are determined by understanding the operation image information, and the operator's posture can be matched. The main display direction is then determined based on the operator's posture, and the display terminal is controlled to rotate to match the main display direction, so that the operator can operate the display terminal;

[0075] 3. By understanding the size relationship between the remaining display area and the baseline display area, the size of the prompt box can be determined. When the size of the prompt box needs to be reduced, the remaining display area can be used to determine the area of the prompt box, thereby reducing the size of the prompt box. This will prevent the prompt box from affecting the staff's operation while allowing the staff to better view the prompt content. BRIEF DESCRIPTION OF THE DRAWINGS

[0083] The present invention is further described in detail below with reference to the accompanying drawings and embodiments.

[0084] An embodiment of the present application discloses a fault diagnosis method for a high-voltage inverter.

[0085] Reference Figure 1 , a fault diagnosis method for a high-voltage inverter, comprising the following steps:

[0086] Step 100: Obtain preset fault detection information of the controller circuit.

[0087] The controller circuit is the electronic circuit used to control the operation of the high-voltage inverter. Fault detection information refers to information generated when a chip in the control circuit fails. This information is obtained by a fault detection chip located within the control circuit. The controller circuit consists of three chips: a DSP, an FPGA, and an ARM processor. Each of these chips is independently connected to the fault detection chip using SPI communication circuitry.

[0088] The ARM chip and DSP chip must be connected to the display terminal via a preset serial port. The serial port refers to a serial communication interface used to connect the ARM and DSP chips to the display terminal. In this embodiment, the serial port is an RS232 serial port. The display terminal is connected to both the DSP and ARM chips via the RS232 serial port. If one of the two chips fails, the fault handling chip controls the other chip to connect to the display terminal and transmit a fault message.

[0089] Step 101: Match the faulty chip from a preset chip database according to the fault detection information.

[0090] A faulty chip refers to a chip in the controller circuit that has a fault. The chip database can be used to match the fault detection information to the corresponding faulty chip. This database contains the correspondence between the fault detection information and the faulty chip. The chip database is a manually set database and will not be described in detail here.

[0091] Step 102: Determine whether the faulty chip is consistent with the preset ARM chip.

[0092] The ARM chip is one of the three main chips in the controller circuit. By determining whether the faulty chip matches the ARM chip, it is determined whether the ARM chip can output chip fault information to the display terminal. The display terminal is a display used to display chip fault information. The ARM chip and the display terminal are connected via an RS232 serial port.

[0093] Step 103: If the faulty chip is inconsistent with the ARM chip, the ARM chip is controlled to output preset chip fault information to a preset display terminal.

[0094] Chip fault information refers to information when a chip fails. Chip fault information is pre-set by those skilled in the art and will not be described in detail here. If the faulty chip is inconsistent with the ARM chip, it means that the ARM chip is not faulty and the ARM chip can be directly controlled to output the chip fault information to the display terminal.

[0095] Step 104: If the faulty chip is consistent with the ARM chip, control the preset DSP chip to output chip fault information to the display terminal.

[0096] If the faulty chip is the same as the ARM chip, it means that the ARM chip is faulty and the DSP chip needs to be controlled to output the chip fault information to the display terminal. The DSP chip is also one of the three main chips in the controller circuit, and the DSP chip is also connected to the display terminal through the RS232 serial port.

[0097] In this embodiment, the ARM chip and the display terminal are interactive by default. When the ARM chip fails, the DSP chip and the display terminal are interactive by default.

[0098] Reference Figure 2 , the fault detection method includes the following steps:

[0099] Step 200: When performing fault detection on the ARM chip, define the ARM chip as a detection chip, define the next chip of the detection chip as an output chip, and define the next chip of the output chip as a receiving chip.

[0100] The three main chips in the controller circuit are linked in a chain structure: DSP, FPGA, ARM, and DSP. When troubleshooting a specific chip in the controller circuit, that chip is defined as the detection chip. The chip immediately following the detection chip is defined as the output chip, and the chip immediately following the output chip is defined as the receiving chip.

[0101] When the ARM chip is used as the detection chip, the output chip is the DSP chip and the receiving chip is the FPGA chip. If the DSP chip is used as the detection chip, the output chip is the FPGA chip and the receiving chip is the ARM chip.

[0102] Step 201: After a preset reference time, obtain the data reception value of the output chip.

[0103] The reference time is the interval used to detect faults in the detection chip. The reference time is set in advance by those skilled in the art and is not detailed here. The received data value is the data value received by the output chip from the detection chip. After the reference time, the detection chip sends the data value to the output chip for fault detection. The received data value is acquired by the data transceiver within the output chip.

[0104] Step 202: Calculate the difference between the data reception value and a preset reference reception value as a data difference value.

[0105] The baseline received value refers to the data value last sent by the detection chip to the output chip. Each chip continuously sends data values to the next chip. The data value currently received by the chip is used as the data received value, and the data received value received at the previous baseline time is used as the baseline received value. If the current data value is the first time it is sent, the baseline received value is zero. The data difference value refers to the difference between two data values. It is calculated by subtracting the baseline received value from the data received value.

[0106] Step 203: Determine whether the data difference value is consistent with a preset reference difference value.

[0107] The baseline difference value is the baseline value when the detection chip is normal. By determining whether the data difference value is consistent with the baseline difference value, we can know whether the detection chip has a fault.

[0108] Step 204: If the data difference value is consistent with the reference difference value, the output chip is controlled to output a normal detection chip signal to a preset fault processing chip.

[0109] The normal signal of the detection chip refers to the signal indicating that the detection chip has no faults. The fault processing chip refers to the chip used to centrally collect the fault information of each chip.

[0110] If the data difference value is consistent with the reference difference value, it means that the detection chip has no fault, and the control output chip outputs the normal signal of the detection chip to the fault processing chip.

[0111] Step 205: If the data difference value is inconsistent with the reference difference value, the output chip is controlled to output the detection chip fault information to the fault processing chip, and the output chip is controlled to output the sum of the reference receiving value and the preset fault correction value to the receiving chip.

[0112] Detection chip fault information refers to information about a detection chip fault. The fault correction value refers to the value that the output chip must add to the baseline received value when a detection chip fault occurs, outputting it to the receiving chip to detect the output chip fault.

[0113] If the data difference value is inconsistent with the reference difference value, it means that there is a fault in the detection chip. It is necessary to control the output chip to output the detection chip fault information to the fault processing chip, and control the output chip to output the sum of the reference receiving value and the fault correction value to the receiving chip.

[0114] Reference Figure 3 , the connection method includes the following steps:

[0115] Step 300: Obtain power information of the fault processing chip.

[0116] The power information refers to the remaining power of the fault processing chip. The power information is obtained by a power sensor set in the fault processing chip.

[0117] Step 301: Determine whether the power information is less than the preset reference power information.

[0118] The baseline power information refers to the power level of the fault handling chip when it is low on power. The baseline power information is pre-set by those skilled in the art and will not be described in detail here. By determining whether the power information is less than the baseline power information, it is determined whether the fault handling chip has sufficient power.

[0119] Step 302: If and only if the power information is less than the reference power information, control the ARM chip to output a low power signal to the display terminal.

[0120] In this embodiment, the fault processing chip is powered by an onboard battery, thereby eliminating the risk of storage failure caused by system power failure during the storage process.

[0121] The low battery signal indicates that the fault handling chip is low on battery. If the battery level is lower than the baseline level, the fault handling chip is low on battery. The ARM chip must be controlled to output a low battery signal to the display terminal, prompting staff to replace the battery in the fault handling chip.

[0122] When the power information is not less than the reference power information, it indicates that the fault processing chip has sufficient power. There is no need to replace the battery, and you can continue to obtain power information.

[0123] Step 303: When the ARM chip fails, the DSP chip is controlled to output a low-power signal and ARM chip failure information to the display terminal.

[0124] ARM chip failure information refers to information generated when the ARM chip fails. Since the default interaction between the ARM chip and the display terminal is achieved by the ARM chip in this embodiment, when the ARM chip fails, the interaction between the DSP chip and the display terminal is adjusted to occur. Therefore, when the ARM chip fails, the DSP chip is controlled to output a low-battery signal and ARM chip failure information to the display terminal.

[0125] Step 304: When the ARM chip has no fault, the ARM chip is controlled to output a low-power signal and DSP chip fault information to the display terminal.

[0126] DSP chip fault information refers to the information when the DSP chip fails. When the ARM chip is not faulty, the ARM chip is directly controlled to output a low power signal and DSP chip fault information to the display terminal.

[0127] If neither the ARM chip nor the DSP chip fails, the ARM chip is controlled to output a low-battery signal to the display terminal.

[0128] If either chip fails, the system needs to be shut down for repair, otherwise it will be unusable. Therefore, it is almost impossible for both communication chips to be damaged at the same time, and it is almost impossible for the fault information to not be output to the display terminal.

[0129] Reference Figure 4 , the adjustment method of the display terminal includes the following steps:

[0130] Step 400: Acquire operation image information of the display terminal.

[0131] The operation image information refers to the image on the display terminal screen. The operation image information is obtained by taking a picture with a camera installed on the display terminal.

[0132] Step 401: Determine whether the operation image information contains a portrait feature.

[0133] Portrait features refer to the portraits present in the image. By determining whether the operation image information contains portrait features, it is possible to determine whether there is a staff member in front of the display terminal. The method of identifying portrait features by operating image information is selected by technical personnel in this field and will not be elaborated here.

[0134] Step 402: If and only if the operation image information includes a portrait feature, determine the portrait distance and the portrait posture according to the operation image information, the portrait feature, and a preset reference object.

[0135] Portrait distance refers to the distance between the staff member and the display terminal. When the operation image information contains portrait features, it means that there is a staff member in front of the display terminal, and the distance between the staff member and the display terminal needs to be identified for subsequent steps. The size of the portrait features in the operation image information can be known through the operation image information, and the portrait distance can be calculated by comparing the size of the reference object. The size and position of the reference object are set in advance by those skilled in the art and will not be described in detail here. The operation image information contains a reference object. Portrait posture refers to the orientation of the staff member's face relative to the display terminal. The portrait posture of the portrait features in the operation image information needs to be identified through a preset posture database. The posture database is obtained based on deep learning of the neural network model, which contains portrait postures. The posture database is a manually set database and will not be described in detail here.

[0136] When the operation image information does not contain a human portrait feature, it means that there is no staff in front of the display terminal, and the operation image information can be continued to be obtained.

[0137] Step 403: When the portrait distance is less than a preset reference portrait distance, a display orientation is matched from a preset posture adjustment library according to the portrait posture.

[0138] The reference portrait distance refers to the maximum distance at which the display terminal and the staff can interact. The reference portrait distance is set in advance by those skilled in the art and will not be described in detail here. The display orientation refers to the orientation of the screen content of the display terminal. When the portrait distance is less than the reference portrait distance, it means that the staff is mishandling the display terminal and needs to adjust the orientation of the display terminal. The display orientation corresponding to the portrait posture can be matched through the posture adjustment library, which contains the correspondence between the portrait posture and the display orientation. The posture adjustment library is a manually set database and will not be described in detail here.

[0139] Step 404: When the display orientation is inconsistent with a preset reference orientation, control the display terminal to rotate to be consistent with the display orientation.

[0140] The reference orientation refers to the orientation of the display terminal when no orientation adjustment is performed. The reference orientation is pre-set by those skilled in the art and will not be described in detail here. If the display orientation is inconsistent with the reference orientation, the display terminal must be rotated to align with the display orientation for easier viewing.

[0141] When the portrait distance is not less than the reference portrait distance or the operation image information does not contain portrait features, the display terminal will restore the display orientation to be consistent with the reference orientation.

[0142] Reference Figure 5 , the adjustment method further comprises the following steps:

[0143] Step 500: Determine the number of portraits based on the operation image information and the portrait features.

[0144] The number of portraits refers to the number of portrait features when the operation image information contains portrait features. The number of portraits is obtained by marking the portrait features in the operation image information and then counting the number of marks.

[0145] Step 501: Determine whether the number of portraits is greater than a preset reference number of portraits.

[0146] The baseline number of portraits refers to the number of portraits when the operating image information contains a small number of portrait features. The baseline number of portraits is pre-set by those skilled in the art and will not be described in detail here. By determining whether the number of portraits is greater than the baseline number of portraits, the number of staff members in front of the display terminal screen is determined.

[0147] Step 502: If the number of portraits is not greater than the number of reference portraits, determine the portrait posture according to the operation image information and the portrait features.

[0148] If the number of portraits is not greater than the reference number of portraits, it means that there are only a few staff members in front of the screen of the display terminal, and then steps 400 to 404 can be directly executed.

[0149] Step 503: If the number of portraits is greater than the reference number of portraits, matching the operator's features from a preset portrait database according to the operation image information.

[0150] If the number of portraits exceeds the baseline number, it indicates that multiple staff members are in front of the display terminal screen, and operator characteristics must be matched for subsequent steps. Operator characteristics refer to the portrait features of the staff member operating the display terminal. The operator characteristics corresponding to the operation image information can be matched using a portrait database, which contains the correspondence between the operation image information and the operator characteristics. The portrait database is a manually configured database and is not detailed here.

[0151] Step 504: Determine the operator's posture based on the operation image information and the operator's characteristics.

[0152] Operator posture refers to the pose of the person operating the display terminal. Operator features can be used to identify the operator operating the display terminal in the operation image information, and then their posture can be recognized. The operator's posture can also be identified from the posture database. The posture database is acquired through deep learning using a neural network model and contains operator posture information.

[0153] Step 505: Match the main display orientation from the posture adjustment library according to the operator's posture.

[0154] The main display orientation refers to the orientation of the staff who are operating the screen content of the display terminal when the number of portraits is greater than the reference number of portraits.

[0155] The main display orientation corresponding to the operator's posture can be matched through the posture adjustment library, which includes the corresponding relationship between the operator's posture and the main display orientation.

[0156] Step 506: When the main display orientation is inconsistent with the reference orientation, control the display terminal to rotate to be consistent with the main display orientation.

[0157] When the main display orientation is inconsistent with the reference orientation, the display terminal needs to be controlled to rotate to be consistent with the main display orientation so that the operating staff can view it.

[0158] Reference Figure 6 , the fault information prompt method includes the following steps:

[0159] Step 600: Obtain status information of the detection chip.

[0160] Status information refers to whether the detection chip is currently faulty. Status information is obtained by calling the fault processing chip.

[0161] Step 601: Determine whether the status information is consistent with the preset fault information.

[0162] Fault information refers to information provided when a fault occurs in the detection chip. Fault information is pre-set by those skilled in the art and will not be described in detail here. Whether a fault occurs in the detection chip is determined by determining whether the status information is consistent with the fault information.

[0163] Step 602: If and only if the status information is consistent with the fault information, obtain the screen operation area of the display terminal.

[0164] If the status information matches the fault information, the detection chip is faulty and the display terminal's screen operation area must be captured for subsequent steps. The screen operation area refers to the area of the screen used by the operator to view content. This area is captured using an infrared detector installed within the display terminal. When the operator manipulates the content on the screen, the color of the content changes, and the area that changes represents the screen operation area.

[0165] If the status information is inconsistent with the fault information, it means that the detection chip has not failed and you can continue to obtain the status information.

[0166] Step 603: Determine an idle screen area according to the screen operation area and a preset terminal screen area.

[0167] The terminal screen area refers to the size of the display terminal's screen. The terminal screen area is pre-determined by those skilled in the art and will not be detailed here. The idle screen area refers to the area on the display terminal screen that is not being operated by a staff member. The idle screen area can be calculated by subtracting the screen operation area from the terminal screen area.

[0168] Step 604: Match a display position from a preset display database according to the idle screen area.

[0169] The display position refers to the location of the prompt box on the display terminal. The prompt box is a bar used to alert personnel to a faulty chip. The display position corresponding to the idle screen area is matched using a display database, which contains the correspondence between idle screen areas and display positions. The display database is a manually configured database and will not be detailed here.

[0170] Step 605: Control the preset prompt box to display the prompt content at the display position.

[0171] The prompt content that the detection chip has failed is displayed in the prompt box at the display position to remind the staff that the detection chip has failed.

[0172] Reference Figure 7 , the prompt method further includes the following steps:

[0173] Step 700: Acquire an infrared detection image of the display terminal.

[0174] Infrared detection images are infrared images of the area surrounding the display terminal, including the display terminal screen. Infrared detection images are captured using an infrared camera.

[0175] Step 701: Determine the blocked field of view area based on the infrared detection image, the screen operation area, and the terminal screen area.

[0176] Blocked view areas are areas of blind spot where content on the display terminal may be obstructed due to personal factors when the operator is operating the terminal. A pre-set infrared database is used to match infrared detection images, screen operation areas, and terminal screen area to blocked view areas. This database contains the corresponding relationships between infrared detection images, screen operation areas, terminal screen area, and blocked view areas. The infrared database is manually configured and will not be detailed here.

[0177] Step 702: Determine the remaining display area based on the blocked visual field area and the terminal screen area.

[0178] The remaining display area refers to the area on the display terminal that does not have a blind spot. The remaining display area can be calculated by subtracting the difference between the terminal screen area and the blocked view area.

[0179] Step 703: Determine whether the remaining display area is smaller than a preset reference display area.

[0180] The reference display area refers to the display area occupied by the prompt box on the display terminal. The reference display area is set in advance by those skilled in the art and will not be described in detail here. By determining whether the remaining display area is smaller than the reference display area, it is determined whether the prompt box needs to be reduced.

[0181] Step 704: If the remaining display area is not smaller than the reference display area, control the prompt box to display the prompt content at the display position.

[0182] If the remaining display area is not smaller than the reference display area, it means that there is no need to reduce the prompt box, and the prompt box can be directly controlled to display the prompt content at the display position.

[0183] Step 705: If the remaining display area is smaller than the reference display area, the area of the prompt box is matched from the display database according to the remaining display area and the display position is updated.

[0184] The prompt box area refers to the area to which the prompt box needs to be reduced. If the remaining display area is smaller than the baseline display area, the prompt box needs to be reduced to fully display the prompt content without affecting the operator's operation. The display database can be used to match the prompt box area and display position corresponding to the remaining display area. It contains the corresponding relationship between the remaining display area, prompt box area, and display position.

[0185] Step 706: Control the prompt box to be adjusted to be consistent with the area of the prompt box, and display the prompt content at the updated display position.

[0186] The control prompt box is adjusted to a size consistent with the prompt box area, and the control prompt box displays the prompt content at the updated display position.
