Description

Technical Field

[0001] The present application relates to the field of fan equipment technology, and in particular to a blower selection method, system, storage medium and intelligent terminal. Background Art

[0002] According to the pressure generated by the fan, fans can be divided into blowers, compressors and ventilators. The outlet pressure of the blower is between 0.015MPa and 0.2MPa. The main components of the blower include the volute, collector and impeller. The impeller is generally composed of four major parts: the wheel cover, the wheel disc, the blades and the shaft disc. The blower transmits energy through the rotation of the impeller.

[0003] In the relevant technology, the amount of wind energy output by the blower is related not only to factors such as the specific voltage, but also to the length of the impeller blades. When the blades are longer, the centrifugal force corresponding to the blades is greater when the impeller rotates at the same speed, and the output wind energy is also greater. Therefore, the staff often consider the blade factor when selecting a blower.

[0004] With respect to the above-mentioned related technologies, the inventor believes that when one end of the air supply outlet of the blower is placed close to other objects such as the wall, the air supply at one end of the air supply outlet of the blower is insufficient. At this time, even if a blower with longer blades is selected, the transmitted energy cannot be larger, and it is easy to cause waste of electric energy. Therefore, it is particularly important to select a blower suitable for the working environment. Summary of the invention

[0005] In order to facilitate buyers to select a suitable blower according to the working environment, the present application provides a blower selection method, system, storage medium and intelligent terminal.

[0006] In a first aspect, the present application provides a method for selecting a blower, which adopts the following technical solution:

[0007] A method for selecting a blower, comprising:

[0008] Obtain air volume demand information and machine-object distance information;

[0009] According to the matching analysis of the air volume demand information and the required leaf length information stored in the preset air volume database, the required leaf length information corresponding to the air volume demand information is determined;

[0010] Determine whether the distance corresponding to the machine-object distance information is greater than the preset permitted distance;

[0011] If the distance corresponding to the machine-object distance information is greater than the permitted distance, a distance safety signal is output, and the corresponding blower is selected according to the required blade length information;

[0012] If the distance corresponding to the machine-object distance information is not greater than the permitted distance, the maximum leaf length information corresponding to the machine-object distance information is determined by matching and analyzing the machine-object distance information and the maximum leaf length information stored in the preset leaf length database;

[0013] Determine whether the length value corresponding to the maximum leaf length information is greater than the length value corresponding to the required leaf length information;

[0014] If the length value corresponding to the maximum leaf length information is greater than the length value corresponding to the required leaf length information, a compliance signal is output, and the corresponding blower is selected according to the required leaf length information;

[0015] If the length value corresponding to the maximum leaf length information is not greater than the length value corresponding to the required leaf length information, a non-matching signal is output.

[0016] By adopting the above technical solution, the machine-object distance information is first obtained to determine whether the air supply port of the blower is close to other objects and affects the air intake. When it is not affected by other objects, the blower with the corresponding blade length can be directly selected according to the user's demand for air volume. When it is affected by other objects, the influence is determined according to the distance from other objects, and blowers with different blade lengths are selected, so that the purchaser can choose a more suitable blower according to the working environment.

[0017] Optionally, when the output does not match the signal, the blower selection method also includes:

[0018] Obtain user demand status information;

[0019] Determine whether the state corresponding to the user demand state information is consistent with the preset required state;

[0020] If the state corresponding to the user's required state information is inconsistent with the required state, a no-match signal is output;

[0021] If the state corresponding to the user demand state information is consistent with the required state, the difference between the permitted distance and the distance corresponding to the machine-object distance information is calculated to obtain the difference distance information;

[0022] According to the matching analysis of the difference distance information and the difference leaf length information stored in the preset distance database, the difference leaf length information corresponding to the difference distance information is determined;

[0023] The sum of the length corresponding to the difference blade length information and the length corresponding to the required blade length information is calculated to determine the actual blade length information, and the corresponding blower is selected according to the actual blade length information.

[0024] By adopting the above technical solution, when no blower can meet the air volume demand under normal circumstances, it is determined whether to recommend to the customer a product that can meet the demand but consumes more energy based on the user's demand for the blower, so that the user can purchase a blower when the demand is more urgent, thereby improving the user's shopping experience.

[0025] Optionally, before selecting a corresponding blower according to the actual blade length information, the blower selection method further includes:

[0026] Determine whether the length corresponding to the actual leaf length information is greater than the preset upper limit length;

[0027] If the length corresponding to the actual leaf length information is greater than the upper limit length, a no-match signal is output;

[0028] If the length corresponding to the actual blade length information is not greater than the upper limit length, the corresponding blower is selected according to the actual blade length information.

[0029] By adopting the above technical solution, it is possible to determine whether there is a blower that meets the customer's requirements in the purchase library, so as to determine whether the customer can purchase the blower.

[0030] Optionally, after the blower selection is completed, the blower inspection method includes:

[0031] Obtaining the blocked area information and the placement position information and placement orientation information of the blower;

[0032] The blade length corresponding to the selected blower is defined as the actual blade length, and the blowing range information is defined according to the actual blade length, the placement position information and the placement direction information;

[0033] Determine whether the range corresponding to the blowing range information has an intersection with the area corresponding to the shielding area information;

[0034] If the range corresponding to the blast area information and the area corresponding to the shielding area information have an intersection, an abnormal signal is output;

[0035] If there is no intersection between the range corresponding to the blast area information and the area corresponding to the shielding area information, a check signal is output.

[0036] By adopting the above technical solution, the placement of the blower is simulated so that the purchaser can know whether the blower can be installed after purchase, thereby reducing the situation where the purchaser cannot install the blower after purchase.

[0037] Optionally, after the inspection signal is output, the blower inspection method further includes:

[0038] Projecting the range corresponding to the air blowing range information in the opposite direction to the direction corresponding to the placement direction information, so as to define the range where the range corresponding to the air blowing range information is projected on the area corresponding to the shielding area information as a shielding range;

[0039] Obtain the distance information of each point within the occlusion range from the area corresponding to the occlusion area information in the opposite direction to the direction corresponding to the placement orientation information;

[0040] Determine the maximum and minimum distance information corresponding to the distance value according to the preset sorting rule, and determine the mean distance information according to the maximum and minimum distance information corresponding to the distance value;

[0041] Determine the occlusion rate information by calculating the range corresponding to the occlusion range and the blast range information;

[0042] According to the mean distance information, occlusion rate information and selection situation information stored in the preset inspection database, matching analysis is performed to determine the selection situation information corresponding to the mean distance information and occlusion rate information;

[0043] Determine whether the situation corresponding to the selected situation information is consistent with the preset normal situation;

[0044] If the situation corresponding to the selected situation information is consistent with the normal situation, a normal signal is output;

[0045] If the situation corresponding to the selected situation information is inconsistent with the normal situation, a wind shortage signal is output.

[0046] By adopting the above technical solution, whether the blower purchased by the shopper can meet the usage requirements can be determined based on the distance between the blower and other objects and the shielding ratio, so as to reduce the situation where the blower cannot meet the actual usage requirements after the shopper purchases it.

[0047] Optionally, after the wind power shortage signal is output, the blower selection method also includes:

[0048] The actual blade length is added to the preset fixed blade length to update the actual blade length, and the blast range information is updated according to the new actual blade length;

[0049] Determine whether the actual leaf length is greater than the upper limit length;

[0050] If the actual leaf length is greater than the upper limit length, a no-match signal is output;

[0051] If the actual leaf length is not greater than the upper limit length, the actual leaf length is continuously updated until an abnormal signal or a normal signal is output.

[0052] By adopting the above technical solution, when the selected blower does not meet the distance and occlusion ratio conditions with other objects, the length of the blower blades can be continuously updated so that shoppers can reselect a blower that meets their actual needs, thereby improving shoppers' purchasing experience.

[0053] Optionally, also include:

[0054] Get the number of selections;

[0055] Determine the number of no-match times information according to the no-match signal count;

[0056] The matching failure rate information is determined by calculating the number of no matches and the number of selections;

[0057] Determine whether the value corresponding to the matching failure rate information is greater than a preset upper limit value;

[0058] If the value corresponding to the matching failure rate information is not greater than the upper limit, a normal operation signal is output;

[0059] If the value corresponding to the matching failure rate information is greater than the upper limit value, then determine whether the number of times corresponding to the selection times information is greater than the preset reference value;

[0060] If the number value corresponding to the selected number information is not greater than the reference value, a normal operation signal is output;

[0061] If the number value corresponding to the selection number information is greater than the reference value, an abnormal operation signal is output.

[0062] By adopting the above technical solution, the blower selection situation can be recorded and analyzed. When a large number of unmatched signals appear, it indicates that the program may be damaged. At this time, an abnormal operation signal is output to inform the shopping platform personnel of the situation so that they can promptly carry out follow-up processing for this situation.

[0063] In a second aspect, the present application provides a blower selection system, which adopts the following technical solution:

[0064] A blower selection system, comprising:

[0065] An acquisition module is used to obtain air volume demand information and machine-object distance information;

[0066] A processing module, connected to the acquisition module and the judgment module, for storing and processing information;

[0067] The processing module matches and analyzes the air volume demand information and the required leaf length information stored in the preset air volume database to determine the required leaf length information corresponding to the air volume demand information;

[0068] A judging module, used to judge whether the distance corresponding to the machine-object distance information is greater than a preset permitted distance;

[0069] If the judging module determines that the distance corresponding to the machine-object distance information is greater than the permitted distance, the processing module outputs a distance safety signal and selects the corresponding blower according to the required blade length information;

[0070] If the judging module judges that the distance corresponding to the machine-object distance information is not greater than the permitted distance, the processing module matches and analyzes the machine-object distance information and the maximum leaf length information stored in the preset leaf length database to determine the maximum leaf length information corresponding to the machine-object distance information;

[0071] The judging module judges whether the length value corresponding to the maximum leaf length information is greater than the length value corresponding to the required leaf length information;

[0072] If the judgment module determines that the length value corresponding to the maximum blade length information is greater than the length value corresponding to the required blade length information, the processing module outputs a compliance signal and selects the corresponding blower according to the required blade length information;

[0073] If the judging module determines that the length value corresponding to the maximum leaf length information is not greater than the length value corresponding to the required leaf length information, the processing module outputs a non-matching signal.

[0074] By adopting the above technical solution, the acquisition module first obtains the machine-object distance information so that the judgment module can determine whether the air supply port of the blower is close to other objects and affects the air intake. When the judgment module determines that it is not affected by other objects, the processing module can directly select the blower with the corresponding blade length according to the user's demand for air volume. When the judgment module determines that it is affected by other objects, the processing module determines the impact according to the distance from other objects, and selects blowers with different blade lengths, so that the purchaser can choose a more suitable blower according to the working environment.

[0075] In a third aspect, the present application provides a smart terminal, which adopts the following technical solution:

[0076] An intelligent terminal comprises a memory and a processor, wherein the memory stores a computer program which can be loaded by the processor and execute any one of the above blower selection methods.

[0077] By adopting the above technical solution and using a smart terminal, the machine-object distance information is first obtained to determine whether the air supply port of the blower is close to other objects and affects the air intake. When it is not affected by other objects, a blower with a corresponding blade length can be directly selected based on the user's demand for air volume. When it is affected by other objects, the influence is determined based on the distance from other objects, and blowers with different blade lengths are selected, so that the purchaser can choose a more suitable blower according to the working environment.

[0078] In a fourth aspect, the present application provides a computer storage medium capable of storing a corresponding program, which has the feature of enabling a purchaser to select a suitable blower according to a working environment, and adopts the following technical solution:

[0079] A computer-readable storage medium stores a computer program that can be loaded by a processor and execute any of the above blower selection methods.

[0080] By adopting the above technical scheme, a computer program for blower selection method is stored in a storage medium, which first obtains the machine-object distance information to determine whether the air supply port of the blower is close to other objects and affects the air intake. When it is not affected by other objects, a blower with a corresponding blade length can be directly selected according to the user's demand for air volume. When it is affected by other objects, the influence is determined according to the distance from other objects, and blowers with different blade lengths are selected, so that the purchaser can choose a more suitable blower according to the working environment.

[0081] In summary, the present application includes at least one of the following beneficial technical effects:

[0082] 1. Select a blower with appropriate blade length according to the distance between the blower and other objects when in use, so that the selected blower can be suitable for the working environment;

[0083] 2. The working condition of the recommended blower can be simulated so that the buyer can more intuitively determine whether the blower can meet the use requirements;

[0084] 3. The blower selection process can be recorded so that when the selection algorithm is abnormal, the shopping platform can be informed and processed in time to improve the shopping experience of shoppers. BRIEF DESCRIPTION OF THE DRAWINGS

[0094] In order to make the purpose, technical solutions and advantages of this application more clear, the following Figure 1-9 It should be understood that the specific embodiments described herein are only used to explain the present application and are not used to limit the present application.

[0095] The embodiments of the present invention are further described in detail below in conjunction with the accompanying drawings.

[0096] The embodiment of the present application discloses a method for selecting a blower, which recommends a suitable blower to a purchaser based on the location where the blower needs to be installed, so that the purchaser can select a blower based on the working environment, thereby reducing the situation where the blower purchased by the purchaser cannot meet actual usage needs.

[0097] Reference Figure 1 The method flow of blower selection includes the following steps:

[0098] Step S100: Obtaining air volume demand information and machine-object distance information.

[0099] The air volume value corresponding to the air volume demand information is the air volume value corresponding to the blower that the purchaser needs to purchase. The size of the air volume value is input by the purchaser. The input method can be determined and converted according to the functional effect that the blower needs to achieve. It is a conventional technical means for technical personnel in this field and will not be elaborated on here. The distance corresponding to the machine-object distance information is the distance from the blower to the surrounding objects determined by the purchaser based on the actual installation location of the blower after purchase and the conditions of the surrounding objects. It is manually input by the purchaser after field measurement.

[0100] Step S101: matching and analyzing the air volume demand information and the required leaf length information stored in the preset air volume database to determine the required leaf length information corresponding to the air volume demand information.

[0101] The length value corresponding to the required blade length information is the blade length value of the impeller when the blower can achieve the air volume value corresponding to the air volume demand information. Different air volume demand information corresponds to different required blade length information. The correspondence between the two is obtained by the staff through multiple experiments. An air volume database can be established based on different air volume demand information and the corresponding required blade length information. The establishment method is a conventional technical means of those skilled in the art and will not be elaborated on.

[0102] Step S102: determining whether the distance corresponding to the machine-object distance information is greater than a preset permitted distance.

[0103] The allowable distance is the maximum distance between the blower and other objects set by the staff that will affect the blower's air volume. The purpose of the judgment is to find out whether the current location where the blower needs to be installed will be affected by other objects.

[0104] Step S1021: If the distance corresponding to the machine-object distance information is greater than the permitted distance, a distance safety signal is output, and a corresponding blower is selected according to the required blade length information.

[0105] When the distance corresponding to the machine-object distance information is greater than the permitted distance, it means that other objects will not affect the air volume at the air inlet of the blower. At this time, a distance safety signal is output to identify and record the situation, so as to select a blower with a corresponding blade length according to the length value corresponding to the required blade length information, so that the blower purchased by the purchaser can meet the usage requirements.

[0106] Step S1022: If the distance corresponding to the aircraft-object distance information is not greater than the permitted distance, the maximum leaf length information corresponding to the aircraft-object distance information is determined by matching and analyzing the aircraft-object distance information and the maximum leaf length information stored in the preset leaf length database.

[0107] When the distance corresponding to the machine-object distance information is not greater than the permitted distance, it means that other objects may affect the air volume at the air inlet of the blower. At this time, the blower needs to be further screened according to this situation; the length value corresponding to the maximum leaf length information is the maximum value of the blade length that will not be affected by other objects at the distance corresponding to the machine-object distance information. Different machine-object distance information corresponds to different maximum leaf length information. The staff conducts experiments based on actual conditions to obtain the corresponding relationship. The leaf length database can be established through different machine-object distance information and the corresponding maximum leaf length information. The establishment method is a conventional technical means of those skilled in the art and will not be elaborated on.

[0108] Step S103: Determine whether the length value corresponding to the maximum leaf length information is greater than the length value corresponding to the required leaf length information.

[0109] The purpose of the judgment is to find out whether the blades of the blower actually required by the staff will be affected by other objects.

[0110] Step S1031: If the length value corresponding to the maximum blade length information is greater than the length value corresponding to the required blade length information, a compliance signal is output, and a corresponding blower is selected according to the required blade length information.

[0111] When the length value corresponding to the maximum blade length information is greater than the length value corresponding to the required blade length information, it means that the blades of the blower required by the staff will not be affected by other objects. At this time, a compliance signal is output to identify the situation, so as to select a blower with a corresponding blade length according to the length value corresponding to the required leaf length information, so that the blower purchased by the purchaser can meet the usage requirements.

[0112] Step S1032: If the length value corresponding to the maximum leaf length information is not greater than the length value corresponding to the required leaf length information, a non-matching signal is output.

[0113] When the length value corresponding to the maximum blade length information is not greater than the length value corresponding to the required blade length information, it means that the blower required by the purchaser will be affected by other objects. At this time, a discrepancy signal is output to record the situation so that the purchaser can be informed of this situation for subsequent purchase of the blower.

[0114] Reference Figure 2 , when the output does not match the signal, the blower selection method also includes:

[0115] Step S200: Obtain user demand status information.

[0116] The state corresponding to the user demand state information is a state signal input by the user after receiving the discrepancy signal. The discrepancy signal can be notified to the purchaser in the form of a pop-up window, and the purchaser can input the corresponding state according to the pop-up window, which includes continuing to purchase or giving up the purchase. The pop-up window method is a conventional technical means for technical personnel in this field and will not be elaborated on.

[0117] Step S201: Determine whether the state corresponding to the user demand state information is consistent with the preset required state.

[0118] The required status is the status set by the platform personnel when the purchaser needs to continue purchasing. The purpose of the judgment is to find out whether the user needs to continue purchasing the blower so that the platform can determine whether it needs to continue recommending the corresponding blower.

[0119] Step S2011: If the state corresponding to the user demand state information is inconsistent with the required state, a no-match signal is output.

[0120] When the state corresponding to the user demand state information is inconsistent with the required state, it means that the buyer has given up the purchase. At this time, a no-match signal is output to record and identify the situation, so as to facilitate subsequent understanding of the buyer's shopping situation.

[0121] Step S2012: If the state corresponding to the user demand state information is consistent with the required state, the difference between the permitted distance and the distance corresponding to the machine-object distance information is calculated to obtain difference distance information.

[0122] When the state corresponding to the user demand state information is consistent with the required state, it means that the purchaser needs to continue purchasing. At this time, it is necessary to recommend a blower that meets the air volume requirements but has a higher power consumption for the purchaser to choose; the distance value corresponding to the difference distance information is the distance difference when the current blower position is not affected by other objects, and the calculation method is the permitted distance minus the distance corresponding to the machine-object distance information.

[0123] Step S202: performing matching analysis on the difference distance information and the difference leaf length information stored in the preset distance database to determine the difference leaf length information corresponding to the difference distance information.

[0124] The length value corresponding to the differential blade length information is the difference between the currently recommended blade length of the blower and the blade length when the air volume requirements are met. Different differential distance information corresponds to different differential leaf length information. The correspondence between the two is obtained by the staff based on multiple tests. The longer the blade length, the greater the air volume, and the less affected by objects. Different differential distance information and corresponding differential leaf length information can be used to establish a distance database. The establishment method is a conventional technical means of those skilled in the art and will not be elaborated on.

[0125] Step S203: Calculate the sum of the length corresponding to the difference blade length information and the length corresponding to the required blade length information to determine the actual blade length information, and select the corresponding blower according to the actual blade length information.

[0126] The length value corresponding to the actual blade length information is the blade length value of the blower that can meet the use requirements of the blower when affected by other objects. The calculation method is the length corresponding to the difference leaf length information plus the length corresponding to the required leaf length information, so that the blower with the corresponding blade length can be selected for users to purchase based on the actual leaf length information.

[0127] Reference Figure 3 Before selecting the corresponding blower according to the actual blade length information, the blower selection method also includes:

[0128] Step S300: Determine whether the length corresponding to the actual leaf length information is greater than a preset upper limit length.

[0129] The upper limit length is the maximum value of the blade length of the blowers available for purchase. The purpose of the judgment is to find out whether the blowers currently available for purchase can meet the needs of the purchaser.

[0130] Step S3001: If the length corresponding to the actual leaf length information is greater than the upper limit length, a no match signal is output.

[0131] When the length corresponding to the actual blade length information is greater than the upper limit length, it means that none of the blowers currently available for purchase can meet the purchaser's needs. At this time, a no-match signal is output to record and mark the situation, so as to facilitate subsequent understanding of the purchaser's shopping situation.

[0132] Step S3002: If the length corresponding to the actual leaf length information is not greater than the upper limit length, a corresponding blower is selected according to the actual leaf length information.

[0133] When the length corresponding to the actual blade length information is not greater than the upper limit length, it means that there are blowers currently available for purchase that can meet the buyer's needs. At this time, the corresponding blower can be selected based on the actual blade length information.

[0134] Reference Figure 4 After the blower selection is completed, the blower inspection method includes:

[0135] Step S400: Obtain shielding area information and placement position information and placement orientation information of the blower.

[0136] The area corresponding to the occlusion area information is the area where the object that can block the blower is located, such as Figure 5 As shown, the position corresponding to the placement position information is the center point of the position where the blower needs to be placed, and the direction corresponding to the placement orientation information is the direction of the blower outlet. All three are manually input by the purchaser based on actual needs.

[0137] Step S401: defining the blade length corresponding to the selected blower as the actual blade length, and defining the blowing range information according to the actual blade length, placement position information and placement orientation information.

[0138] The blade length corresponding to the selected blower is defined as the actual blade length for identification, which is convenient for subsequent simulation of the actual installation of the blower; the range corresponding to the blowing range information is the width range that the blade can cover, combined with Figure 5 Shown for illustration.

[0139] Step S402: Determine whether the range corresponding to the blowing range information has an intersection with the area corresponding to the shielding area information.

[0140] The purpose of the judgment is to find out whether the blower recommended for purchase can be installed in the actual site.

[0141] Step S4021: If there is an intersection between the range corresponding to the blowing area information and the area corresponding to the shielding area information, an abnormal signal is output.

[0142] When the range corresponding to the blowing area information intersects with the area corresponding to the shielding area information, it means that the recommended blower cannot be installed in the actual site. At this time, an abnormal signal is output to record the situation so that the purchaser can know the actual usage of the blower in time.

[0143] Step S4022: If there is no intersection between the range corresponding to the blast area information and the area corresponding to the shielding area information, a check signal is output.

[0144] When there is no intersection between the range corresponding to the blowing area information and the area corresponding to the shielding area information, it means that the recommended blower can be installed in the actual site. At this time, a test signal is output to record the situation for further selection of the blower.

[0145] Reference Figure 6 After the inspection signal is output, the blower inspection method further includes:

[0146] Step S500: Project the range corresponding to the air blowing range information in the opposite direction to the direction corresponding to the placement direction information, so as to define the range where the range corresponding to the air blowing range information is projected on the area corresponding to the shielding area information as a shielding range.

[0147] The area on the blower that is blocked by other objects is determined based on the projection, and the range is defined as this range for marking, so as to facilitate further analysis of the overall condition of the blades.

[0148] Step S501: obtaining distance information of each point within the occlusion range from the area corresponding to the occlusion area information in the direction opposite to the direction corresponding to the placement orientation information.

[0149] The distance value corresponding to the distance information is the distance between each point on the occlusion range and the occluding object in the opposite direction to the direction corresponding to the placement orientation information. It is obtained by analyzing the model coordinates, which is a conventional technical means for technicians in this field and will not be elaborated on.

[0150] Step S502: Determine the distance information corresponding to the maximum and minimum distance values ​​according to the preset sorting rule, and determine the mean distance information according to the distance information corresponding to the maximum and minimum distance values.

[0151] The sorting rule is a method that can sort the size of values, such as the bubble method. The sorting rule can be used to determine the distance information with the largest corresponding distance value and the smallest corresponding distance value. The distance value corresponding to the mean distance information is the mean distance of the obstruction range on the blower from the obstructing object. The calculation method is the distance information with the largest corresponding distance value plus the distance information with the smallest corresponding distance value and then divided by two.

[0152] Step S503: Determine the shielding rate information by calculating the range corresponding to the shielding range and the blowing range information.

[0153] The value corresponding to the occlusion rate information is the proportion of the blower that is blocked by other objects, and is calculated by dividing the range length corresponding to the occlusion range by the range length corresponding to the blowing range information.

[0154] Step S504: performing matching analysis on the mean distance information, occlusion rate information and selection situation information stored in the preset inspection database to determine the selection situation information corresponding to the mean distance information and occlusion rate information.

[0155] The situation corresponding to the selection situation information is whether the blower selected under the mean distance information and the occlusion rate information meets the actual needs. Different mean distance information and different occlusion rate information correspond to different selection situation information. The specific situation is obtained by the staff based on multiple tests. The inspection database is established according to different mean distance information, occlusion rate information and selection situation information. The establishment method is a conventional technical means of technical personnel in this field and will not be elaborated on.

[0156] Step S505: Determine whether the situation corresponding to the selected situation information is consistent with the preset normal situation.

[0157] The normal situation is the situation set by the staff that the purchased blower can be used normally. The purpose of the judgment is to know whether the currently purchased blower can meet the use requirements.

[0158] Step S5051: If the situation corresponding to the selected situation information is consistent with the normal situation, a normal signal is output.

[0159] When the situation corresponding to the selected situation information is consistent with the normal situation, it means that the recommended blower can meet the purchaser's needs. At this time, a normal signal is output to record the situation so that the purchaser can know the specific purchase situation.

[0160] Step S5052: If the situation corresponding to the selected situation information is inconsistent with the normal situation, a wind shortage signal is output.

[0161] When the situation corresponding to the selected situation information is inconsistent with the normal situation, it means that the purchased blower cannot meet the purchaser's usage needs. At this time, an insufficient wind force signal is output to record the situation, so as to facilitate subsequent replacement of the recommended blower.

[0162] Reference Figure 7 After the wind power shortage signal is output, the blower selection method also includes:

[0163] Step S600: The actual blade length is added to the preset fixed blade length to update the actual blade length, and the blast range information is updated according to the new actual blade length.

[0164] The fixed blade length is the unit difference blade length of the blower blades available for purchase, that is, after the actual blade length is updated, there are blades with corresponding length among the blower blades available for purchase; the blowing range information can be updated according to the new actual blade length, thereby realizing a re-determination of the updated blower.

[0165] Step S601: Determine whether the actual leaf length is greater than the upper limit length.

[0166] The purpose of the determination is to find out whether the blower blade length required after the update is available in the blowers available for purchase.

[0167] Step S6011: If the actual leaf length is greater than the upper limit length, a no match signal is output.

[0168] When the actual blade length is greater than the upper limit length, it indicates that there is no blower that meets the requirements among the blowers available for purchase. At this time, a no-match signal is output to record the situation, so as to facilitate subsequent understanding of the purchaser's shopping situation.

[0169] Step S6012: If the actual leaf length is not greater than the upper limit length, the actual leaf length is continuously updated until an abnormal signal or a normal signal is output.

[0170] When the actual blade length is not greater than the upper limit length, it means that there is a blower that meets the requirements among the blowers available for purchase. The signal is continuously updated until an abnormal signal or a normal signal is output to update the recommended products to the buyer, so that the buyer can select a more suitable blower that meets the requirements.

[0171] Reference Figure 8 , the blower selection method also includes:

[0172] Step S700: Obtaining selection frequency information.

[0173] The number value corresponding to the number of selection times information is the total number of selection processes of different shoppers on the shopping platform, which can be obtained by counting the number of times the purchaser inputs the air volume requirements. This is a conventional technical means for those skilled in the art and will not be elaborated on.

[0174] Step S701: Determine the number of no-match times according to the no-match signal count.

[0175] The number of times corresponding to the number of no-matching information is the total number of no-matching signals, which is obtained by a counting method. The counting method is a conventional technical means for those skilled in the art and will not be described in detail.

[0176] Step S702: Calculate and determine the matching failure rate information based on the number of no matches and the number of selections.

[0177] The value corresponding to the matching failure rate information is the probability value of no match in the user selection, and the calculation method is to divide the value corresponding to the number of no match information by the value corresponding to the number of selection information.

[0178] Step S703: Determine whether the value corresponding to the matching failure rate information is greater than a preset upper limit.

[0179] The upper limit is the maximum value of the matching failure rate allowed when the program is running normally, which is set by the staff. The purpose of the judgment is to find out whether the current program is likely to be abnormal.

[0180] Step S7031: If the value corresponding to the matching failure rate information is not greater than the upper limit, a normal operation signal is output.

[0181] When the value corresponding to the matching failure rate information is not greater than the upper limit value, it indicates that the selection algorithm program is in a normal operating state. At this time, a normal operation signal is output to record the situation so that the shopping platform staff can know the program operation status.

[0182] Step S7032: If the value corresponding to the matching failure rate information is greater than the upper limit value, it is determined whether the number of times corresponding to the selection times information is greater than a preset reference value.

[0183] When the value corresponding to the matching failure rate information is greater than the upper limit, there may be a situation where the number of selections is small and the matching failure rate is high, and this situation needs to be further judged; the benchmark value is the minimum number of selections when the matching failure rate value set by the staff is counted, and the purpose of the judgment is to know whether the current matching failure rate is counted.

[0184] Step S70321: If the number value corresponding to the selection number information is not greater than the preset reference value, a normal operation signal is output.

[0185] When the number value corresponding to the selection number information is not greater than the reference value, it means that the current matching failure rate cannot determine whether the current program is running normally. At this time, a normal operation signal is output to record the situation.

[0186] Step S70322: If the number value corresponding to the selection number information is greater than the reference value, an abnormal operation signal is output.

[0187] When the number value corresponding to the number of selection information is greater than the benchmark value, it means that the current matching failure rate can be used to judge whether the current program is running normally. At this time, the matching failure rate is too high and there is an abnormal operation of the program algorithm. At this time, an abnormal operation signal is output to identify the situation so that the staff of the shopping platform can deal with the situation in a timely manner.
