Description

Technical Field

[0001] The present invention relates to the technical field of air conditioner inverters, and in particular to a performance optimization method and device for an air conditioner inverter. Background Art

[0002] Air conditioning frequency conversion technology is a conversion technology that converts direct current into alternating current of different frequencies. Devices using frequency conversion technology need to work for a long time and have complex operating conditions, so occasional failures are inevitable. In order to facilitate subsequent users to know the type of failure that occurred in the device, it is necessary to set corresponding fault codes for different types of failures in advance. However, users can only determine what fault has occurred based on the fault code, but cannot determine which module of the inverter has failed.

[0003] If you need to determine why a device fails, you usually need to use an oscilloscope to monitor the device's current waveform and bus voltage waveform, and then combine the specific operating data and engineer experience to locate the cause of the failure. Since adding an oscilloscope reduces the installation space of the air-conditioning inverter, it is impossible to connect each module on the air-conditioning inverter to the oscilloscope for monitoring. This not only increases the energy loss, but also increases the load of the air-conditioning inverter itself. Summary of the invention

[0004] The purpose of the present invention is to provide a performance optimization method and device for an air-conditioning inverter, which can obtain sampling data with different sampling periods, thereby facilitating the subsequent analysis of performance parameters from different angles, that is, it is conducive to improving the accuracy of the subsequent analysis results, aiming to solve the problems in the prior art.

[0005] The present invention is implemented as follows: a performance optimization method for an air conditioner inverter is applied to an inverter monitoring device, specifically comprising the following steps: S101: Receive a first performance parameter detection request of a frequency converter, where the first performance parameter detection request carries a first performance parameter, a periodic record of the first performance parameter detection, and a file format of the first performance parameter detection request; S102: Obtaining a content text of the first performance parameter, inputting the first performance parameter into a preset content text recognition model, and obtaining a data recognition result output by the content text recognition model based on the first performance parameter; S103: collecting a second performance parameter of the inverter, obtaining a content text of the second performance parameter, comparing the content text with a data recognition result of the first performance parameter output, and obtaining a difference threshold feature based on the second performance parameter and the first performance parameter; S104: in the information editing interface of the frequency converter monitoring device, obtaining a difference threshold feature identifier, obtaining a matching option specified by the difference threshold feature, and detecting whether a corresponding matching request exists for the specified matching option; S105: If the specified matching option has a corresponding matching request, determine the specific difference value of the difference threshold feature in the matching request, convert the matching request into an adjustment request for each specific difference value, send the difference threshold feature identifier and the specific difference value to the air-conditioning inverter, and complete the performance optimization of the air-conditioning inverter.

[0006] Further, in S101, receiving a first performance parameter detection request of the inverter includes: Receiving a connection request sent by each module in the frequency converter through a preset network, wherein the connection request is used to request to establish a connection with the frequency converter monitoring device; Determine the current detection unit of the request sent in each module in the frequency converter; After the current detection unit is determined, a connection is made with the current detection unit according to the connection request. After the connection is completed, a first performance parameter detection request of the frequency converter is received.

[0007] Further, the first performance parameter detection request carries the first performance parameter, a periodic record of the first performance parameter detection, and a file format of the first performance parameter detection request, including: According to the sampling period preset by each module in the frequency converter, each module in the frequency converter collects the first performance parameter according to the preset sampling period; The obtained first performance parameters are formatted and the first performance parameters after format identification are uniformly converted to obtain the first performance parameters in a uniform format.

[0008] Furthermore, the preset network includes one or a combination of a 3G network, a 4G network, a 5G network, and a WIFI network.

[0009] Further, in S102, obtaining the content text of the first performance parameter and inputting the first performance parameter into a preset content text recognition model includes: Acquire multiple text recognition models, and sort the recognition parameter types of the multiple text recognition models in order; Obtain the content text of the first performance parameter, and input the first performance parameter into the content text recognition model ranked first.

[0010] Furthermore, in S103, the second performance parameter of the inverter is collected to obtain the content text of the second performance parameter, including: The frequency converter monitoring device generates a request for collecting the second performance parameter and sends it to the connected current detection unit, and after receiving the request, the current detection unit immediately performs the performance parameter collection of the current detection unit; The periodic record of collecting the performance parameters of the current detection unit is greater than twice the periodic record of the first performance parameter detection; The acquired second performance parameter of the frequency converter is recognized again through the content text recognition model and then compared with the data recognition result outputted from the first performance parameter.

[0011] Further, in S104, in the information editing interface of the frequency converter monitoring device, a difference threshold feature identifier is obtained, and a matching option specified by the difference threshold feature is obtained, including: Acquire the difference threshold feature identified in S103, and identify the difference threshold feature of the inverter performance parameter, including the performance parameter type, performance parameter increase, and performance parameter increase value of the second performance parameter and the first performance parameter; The matching options specified by the difference threshold characteristics are obtained, and the matching options include the correlation index of the performance parameters. The inverter monitoring device compares the correlation index of the current performance parameters with the correlation index of the performance parameters preset by the system to determine the correlation between the matching options and the difference threshold characteristics. If the correlation is within the system preset correlation threshold, a corresponding matching request is generated.

[0012] Further, in S105, if the specified matching option has a corresponding matching request, specific difference values ​​of the difference threshold feature in the matching request are determined, and the matching request is converted into adjustment requests of each specific difference value, including: If the specified matching option does not have a corresponding matching request, determining corresponding data in the difference threshold feature, and outputting it to the information editing interface of the frequency converter monitoring device in sequence; After the command of the information editing interface is entered, the matching options specified by the difference threshold feature in the information editing interface are obtained, and the specific difference value of the difference threshold feature is re-confirmed according to the matching options, and then the difference threshold feature identifier and the specific difference value are sent to the air-conditioning inverter to complete the performance optimization of the air-conditioning inverter.

[0013] Compared with the prior art, the performance optimization method and device of an air conditioner inverter provided by the present invention have the following beneficial effects: 1. Through the self-collected first performance parameter and the passively collected second performance parameter, all-round identification and detection are performed, and the difference threshold characteristics based on the second performance parameter and the first performance parameter are obtained, accurate analysis results can be obtained, the cause of the fault and the operating status data of each module in the inverter can be obtained, which is convenient for rapid maintenance and performance optimization of the corresponding module. At the same time, since the fault data is recorded by the inverter itself, there is no need to connect the inverter to the oscilloscope, so the convenience of operation can be improved. The performance parameters of the inverter are sampled through 2 different sampling periods, so sampling data with different sampling periods can be obtained, which is conducive to the subsequent analysis of the performance parameters from different angles, that is, it is conducive to improving the accuracy of the subsequent analysis results; 2. Obtain the difference threshold feature identifier, obtain the matching options specified by the difference threshold feature, and detect whether the specified matching option has a corresponding matching request. If the specified matching option has a corresponding matching request, determine the specific difference value of the difference threshold feature in the matching request, and convert the matching request into an adjustment request for each specific difference value. If the specified matching option does not have a corresponding matching request, determine the corresponding data in the difference threshold feature, and complete the output to the information editing interface of the inverter monitoring device in sequence. Re-determine the specific difference value of the difference threshold feature according to the matching option, and then send the difference threshold feature identifier and the specific difference value to the air-conditioning inverter to complete the performance optimization of the air-conditioning inverter, thereby ensuring that the performance adjustment of the inverter is based on closely related coefficients to complete the performance adjustment, and avoiding the problem of inverter performance degradation caused by incorrect model identification performance parameters.

The first performance parameter collected autonomously and the second performance parameter collected passively are used for all-round identification and determination, and the difference threshold feature based on the second performance parameter and the first performance parameter is obtained. Accurate analysis results can be obtained, and the cause of the fault and the operating status data of each module in the inverter can be obtained, which is convenient for rapid maintenance and performance optimization of the corresponding modules.

[0021] In S101 of this embodiment, the first performance parameter detection request carries the first performance parameter, a periodic record of the first performance parameter detection, and a file format of the first performance parameter detection request, including: According to the sampling period preset by each module in the frequency converter, each module in the frequency converter collects the first performance parameter according to the preset sampling period; The obtained first performance parameters are formatted and converted uniformly to obtain the first performance parameters in a uniform format. Since the fault data is recorded by the frequency converter itself, there is no need to connect the frequency converter to an oscilloscope.

[0022] Specifically, the file format of the performance parameter detection request may be as follows: COCO format, COCo dataset format is a commonly used annotation data format, which includes a JSON file and a series of image files. The JSON file contains image information, category labels, bounding box coordinates, etc. This format is suitable for tasks such as target detection and instance segmentation.

[0023] VOC format, VOC dataset format is also a common annotated data format. It usually includes an XML file and a series of image files. The XML file contains image information, category labels, bounding box coordinates, etc. Similar to the COCO format, VOC format is also suitable for tasks such as target detection and instance segmentation.

[0024] YOLO format is a popular target detection algorithm. Its annotation data format usually includes a text file, and each line corresponds to the annotation information of an image, including category label, bounding box center coordinates, width, height, etc.

[0025] In this embodiment, the preset network includes one or a combination of a 3G network, a 4G network, a 5G network, and a WIFI network.

[0026] The technical solution can improve the convenience of operation. The performance parameters of the frequency converter are sampled through two different sampling periods. Therefore, sampling data with different sampling periods can be obtained, which is conducive to the subsequent analysis of the performance parameters from different angles, that is, it is conducive to improving the accuracy of the subsequent analysis results.

[0027] Specifically, the performance parameters of the inverter may include the following: 1. Frequency: The frequency of the inverter output can be calculated as follows: Output frequency = input frequency x speed ratio; Among them, the speed ratio is usually set through the control panel or program of the inverter, generally between 0.1-1.

[0028] 2. Speed: The speed output by the inverter can be calculated as follows: Output speed = input speed x speed ratio; Among them, the input speed refers to the speed of the motor, which is usually calculated based on the rated power and rated speed.

[0029] 3. Voltage: The voltage output by the inverter can be calculated as follows: Output voltage = input voltage x modulation index; The modulation index refers to the change in the inverter output waveform. When the modulation index is 1, the output waveform is closest to a sine wave. When the modulation index is greater than 1, the output waveform becomes sharper and may have an adverse effect on the motor. For example, if the input voltage is 380V and the modulation index is 1, the output voltage is also 380V.

[0030] Ordinary motors are designed and manufactured according to 50Hz voltage, and their rated torque is also given within this voltage range. When the inverter output frequency is greater than 50Hz, the torque generated by the motor decreases in a linear relationship that is inversely proportional to the frequency.

[0031] When the motor runs at a frequency greater than 50 Hz, the size of the motor load must be considered to prevent insufficient motor output torque.
