[0055] It should be understood that the specific embodiments described herein are only used to explain the present invention, and are not used to limit the present invention.

[0056] See also Figure 1 1 is a functional module diagram of an after-sales service system based on electric tools according to an embodiment of the present invention. The after-sales service system based on electric tools 100 comprises an electric tool 101 , a cloud server 102 and a client 103 .

[0057] See also Figure 2 , which is a functional module diagram of an electric tool in an after-sales service system, the electric tool 101 includes: a sensor 1011 , an information collection unit 1012 , a control unit 1013 , a communication unit 1014 and a storage unit 1015 .

[0058] In an embodiment of the present invention, the electric tool includes a chain saw, a pruner, a lawn mower, an intelligent lawn mower, an electric vehicle, and the like.

[0059] In an embodiment of the present invention, the sensor is used to detect the working parameters of the power tool, and the working parameters may be the operating parameters of the power tool, such as motor current and voltage, battery charge, motor and battery usage time, motor speed, battery output voltage, output current, output power, current location, GPS positioning, mileage, etc.

[0060] In the embodiment of the present invention, after the electric tool is repaired, the information of the updated components can be re-entered through the sensor, and a maintenance record can be generated according to the parameters of the electric tool before and after the repair.

[0061] In the embodiment of the present invention, the information collection unit is used to collect the working parameters of the electric tool. If different faults occur in the electric tool, different fault codes will be generated. The information collection unit can also be used to collect fault information (for example, fault codes).

[0062] See also Figure 3 As shown, in the embodiment of the present invention, when the information collection unit performs the function of collecting the working parameters of the electric tool, it is specifically used to:

[0063] S31, acquiring sensor data detected by the sensor of the electric tool through a sensor interface;

[0064] S32: Process and convert the sensor data to obtain working parameters of the electric tool.

[0065] Specifically, in an embodiment of the present invention, the sensor interface can be I2C, SPI, UART, or analog input (such as voltage, current) to achieve connection; the information acquisition unit can collect data collected by the sensor in real time through the sensor interface, including reading analog signals, parsing digital signals or receiving data packets provided by the sensor; data processing and data conversion of the sensor data include unit conversion, filtering, calibration, data formatting and other operations.

[0066] In an embodiment of the present invention, the control unit is used to send control instructions to components in the power tool and receive detection information returned by the components of the power tool according to the control instructions; wherein the control instructions are used to control the power tool to run a program detection component.

[0067] Specifically, in the embodiment of the present invention, the control unit generates a control instruction according to a human-computer interaction trigger, or the control unit automatically generates a control instruction when a component of the electric tool is installed or replaced.

[0068] In an actual application scenario of the present invention, when a user purchases an electric tool to install or replace components in the electric tool, after installing it according to the installation steps obtained by the client from the cloud server, a control instruction can be generated based on the human-computer interaction of the client or the human-computer interaction button of the electric tool. The control instruction controls the electric tool to run a program to detect whether the component is installed successfully so as to perform normal functions; or, the components of the electric tool can automatically generate control instructions to achieve self-check operation.

[0069] For example, after replacing spare parts of an electric tool, a standard procedure will be run to check whether the spare parts are qualified. For specific components of a lawn mower, such as buttons and sensors, human-computer interaction is required. The repairer / user needs to press the button according to the instructions and lift or push the lawn mower body to trigger the generation of control instructions to achieve functional inspection. Components such as motherboards and radars can automatically generate control instructions through the processor to control and obtain detection information without the need for human interaction with the machine.

[0070] In an embodiment of the present invention, the communication unit is used to upload the working parameters, the fault information and the detection information to the cloud server, and both users and manufacturers can obtain data through the client. Specifically, users can only obtain the relevant parameters of the power tools bound to them, while manufacturers can obtain the relevant parameters of all successfully uploaded power tools.

[0071] Specifically, the communication unit may be a SIM card, Bluetooth, WiFi, data cable or other methods, and communication with the cloud server may be achieved through the communication unit.

[0072] In the embodiment of the present invention, before executing the function of uploading the working parameters, the fault information and the detection information to the cloud server, the communication unit is further used to:

[0073] Obtaining the communication status of the communication unit, and determining whether the communication status is connected;

[0074] If the communication status is connected, uploading the working parameters, the fault information and the detection information to the cloud server;

[0075] If the communication status is disconnected, the working parameters, the fault information and the detection information are uploaded to the storage unit.

[0076] See also Figure 4 As shown, in the embodiment of the present invention, when the communication unit performs the function of uploading the working parameters, the fault information and the detection information to the cloud server, it is specifically used to:

[0077] S41, taking the working parameters, the fault information and the detection information as data to be uploaded, and performing data format conversion on the data to be uploaded to obtain a data packet;

[0078] S42, connecting the communication unit and the cloud server according to a communication protocol;

[0079] S43: After the communication unit is successfully connected to the cloud server, the data packet is transmitted to the cloud server according to network transmission.

[0080] In an embodiment of the present invention, the data packet for data format conversion to be uploaded may be in JSON or XML protocol format; the communication protocol may be HTTP, MQTT or other protocols; when connecting the communication unit and the cloud server, the identity of the communication unit may be corrected to verify the upload authority and ensure the security of the data in the cloud server; network transmission may be performed through HTTP POST requests, TCP / IP sockets or other methods to transmit the data packet to the cloud server.

[0081] Furthermore, after receiving the uploaded data packet, the cloud server also includes operations such as data parsing, verification, and storage in a database or other data storage system; and the cloud server can also send a confirmation message to the communication unit to ensure that the data has been successfully received and processed. Specifically, it can send an HTTP response code, reply to an MQTT message, etc. for confirmation.

[0082] In an actual application scenario of the present invention, after the electric tool is successfully connected to the cloud, various parameter data recorded by the sensor during the use of the electric tool will be uploaded to the cloud server; if the user wants to query the product failure of the electric tool, the user can go to the cloud server through the serial number of the electric tool to obtain the corresponding relevant parameter information.

[0083] In the embodiment of the present invention, the storage unit is used to store the working parameters, the fault information and the detection information when the communication of the communication unit is blocked.

[0084] The cloud server is used to use the working parameters, the fault information and the detection information as equipment data, perform fault classification and health detection according to the equipment data, and obtain early warning results; divide the equipment data into multiple dimensions to obtain dimensional data, and generate a product after-sales portrait based on the dimensional data.

[0085] In the embodiment of the present invention, the working parameters are parameters generated during the use of the power tool. With the increase in the number of uses and the length of use, the components in the power tool will have different degrees of wear and functional loss. Therefore, by analyzing the working parameters, the health status of the power tool can be determined; when different faults occur in the power tool, different fault codes will be generated to indicate the fault conditions of the power tool, and the health status of the power tool can be judged according to the fault conditions of the power tool; the health status of the power tool can be used to provide different forms of safety warnings for the power tool to ensure the safety of the power tool and the corresponding users.

[0086] See also Figure 5 As shown, in the embodiment of the present invention, when the cloud server performs the function of performing fault classification and health detection according to the device data to obtain the warning result, it is specifically used to:

[0087] S51, performing health detection according to the working parameters in the device data to obtain the health status of the components in the power tool;

[0088] S52, classifying the fault levels according to the health status and the fault information in the device data to obtain the fault levels of the components in the power tool;

[0089] S53: Perform graded warning according to the fault level.

[0090] In an embodiment of the present invention, components in the power tool may have different health states according to different degrees of usage. Different health states may be visually displayed in a distinctive manner in the client through different colors to inform the user whether the components of the power tool are healthy and whether their functions are normal. However, the prognostic measures corresponding to different degrees of health states are not the same. For components of the power tool in poor health states, there may be faults that cannot be eliminated, which may affect the normal use of the power tool. Different health states may be divided into different levels of fault levels. In addition, different fault information may have different corresponding fault levels. For example, the faults of the power tool may be roughly divided into three levels: level one fault prompts, such as reminders that the engine oil needs to be replaced or the blade needs to be replaced; level two fault prompts, which are faults that can be eliminated after restarting, such as a full grass box, a motor overload, etc.; level three fault prompts, which are faults that require repair, such as a damaged motor or a damaged battery.

[0091] In the embodiment of the present invention, when the cloud server performs the function of dividing the device data into multiple dimensions to obtain dimensional data, it is specifically used to:

[0092] Extracting data attributes of the device data, and using the data attributes as data dimensions;

[0093] The device data is clustered according to the data dimension to obtain dimensional data.

[0094] In an embodiment of the present invention, data dimensions may include characteristic dimensions, time dimensions, geographic dimensions, etc.; specifically, characteristic dimensions refer to dividing product data according to different product characteristics. For example, for power tools, the data may be divided according to product characteristics such as the type of power tool, the corresponding product model, and the corresponding product function; time dimensions refer to dividing product data according to time in order to observe the sales changes of products in different time periods. The data may be divided according to time dimensions such as years, quarters, and months; geographic dimensions refer to dividing product data according to geographic locations in order to understand the sales situation and market demand of products in different regions. The data may be divided according to geographic dimensions such as countries, states / provinces, and cities.

[0095] In the embodiment of the present invention, through multi-dimensional division, the changes and relationships of the electric tool in different dimensions can be deeply understood to assist the subsequent optimization and improvement of the electric tool.

[0096] In the embodiment of the present invention, when the cloud server executes the function of generating a product after-sales portrait according to the dimensional data, it is specifically used to:

[0097] Performing data cleaning on the dimensional data to obtain standard data;

[0098] Assigning weights to the standard data to obtain weighted data;

[0099] A portrait is constructed according to the data dimensions of the dimensional data and the weight data to obtain a product after-sales portrait.

[0100] In the embodiment of the present invention, by integrating and cleaning the generated multi-dimensional data, the accuracy and consistency of the data can be ensured; by evaluating and assigning weights to data of different dimensions, important dimensional data can be highlighted.

[0101] In the embodiment of the present invention, the data dimension of the dimensional data can be used as a portrait label, and the portrait label and weight data are summarized and counted to obtain the product after-sales portrait. Taking the after-sales portrait of a lawn mower as an example, the after-sales portrait includes the product model, sales time, sales area, etc. of the lawn mower, and the corresponding weight data is assigned according to different emphases.

[0102] See also Figure 6As shown, in an embodiment of the present invention, the product after-sales portrait can be visualized through a client. Specifically, charts, graphs, indicators, etc. can be used to intuitively display the characteristics of the power tool in multiple dimensions; the product after-sales portrait is dynamic, and as the dimensional data of the power tool changes, it will be continuously updated and improved to achieve the update of the dimensional data, and regenerate and adjust the product after-sales portrait; by generating the product after-sales portrait, it is possible to have an in-depth understanding of the situation of the power tool in multiple dimensions, help R&D personnel better locate the target market and consumer groups of the power tool, and promote product improvement.

[0103] For example, if a lawn mower in a certain area frequently fails due to overload of the mowing motor, while the efficiency of the travel motor has been below 30%, then when developing subsequent models, it is necessary to pay attention to increasing the power of the mowing motor and reducing the power of the travel motor; if lawn mowers in a certain area often have insufficient power and long working hours, high-power models of this equipment can also be recommended to users through relevant clients.

[0104] The client is used to obtain target data from the cloud server according to the query instruction and to visualize the target data.

[0105] In an embodiment of the present invention, the query instruction may be a serial number, serial number, etc. of the electric tool, and relevant parameter information of the corresponding electric tool may be obtained based on the serial number; if the electric tool is under maintenance, the query instruction may be a maintenance instruction for a component required for maintenance in the electric tool, and the maintenance steps (i.e., target data) of the component required for maintenance may be obtained through the maintenance instruction. For example, if the component required for maintenance is a lawn mower mainboard, the maintenance instruction is determined based on the type and model of the lawn mower mainboard to obtain the corresponding maintenance steps, and the maintenance personnel or user may perform maintenance on the lawn mower according to the maintenance steps.

[0106] In the embodiment of the present invention, the target data can be visualized through a visualization tool or library, and the visualization tool includes: Matplotlib, D3.js, Tableau, Power BI, etc.

[0107] In the embodiment of the present invention, after the target data is the relevant parameters of the electric tool, the client can display the target data differently according to the permissions, tool attributes, etc. For example, the relevant parameters of the electric tool can be divided into general information and advanced information, such as device information, control device status, and device configuration information, etc., which belong to general information, and component real-time information is advanced information. When the client is a user, the content to be visualized is general information; when the client is a manufacturer, the content to be visualized is general information and advanced information.

[0108] In the embodiment of the present invention, when the target data is the warning result obtained by fault classification and health detection based on the device data, the client can display the results obtained by fault classification and health detection in a differentiated manner. Figure 7 As shown in the figure, it is a UI page display diagram of components in electric work, where component A (main controller), component B, component L, component R, component M, etc. can be displayed differently according to different health conditions. For the main controller A, the controller temperature, wheel speed, wheel motor current, wheel motor temperature and other parameter information can also be displayed on the page. Specifically, the components in the power tool will have different health conditions according to different degrees of use. When the health status of the component is normal use, the component can be displayed in green; when the health status of the component is close to the service life and needs to be replaced, the component can be displayed in yellow; when the health status of the component is after the service life or the component has a fault that cannot be eliminated, the component can be displayed in red.

[0109] The present invention can realize functions such as data detection, collection, uploading, and storage through electric tools, realize the intelligence of electric tools, and improve the efficiency of electric tool Internet of Things; upload data to the cloud server for processing through the electric tool, and based on the linkage between the electric tool and the cloud server, realize efficient processing of relevant data of the electric tool; through the data transmission between the cloud server and the client, the three-end interaction of the electric tool-cloud server-client can be realized, and the timely update and processing of the after-sales data of the electric tool is realized, the safety of user use is ensured, the user experience is improved, and support is given to the after-sales optimization of the electric tool. Therefore, the after-sales service system based on electric tools proposed in the present invention mainly aims to solve the problem that product data cannot be accurately obtained after the sale of electric tools and the after-sales service optimization of products based on product data is realized, and the user experience is improved.
