Description

Technical Field

[0001] The invention relates to the technical field of plate spraying control, and in particular to an automatic intelligent control system for plate spraying. Background Art

[0002] As a decorative material, the board can be protected by surface spraying after processing to enhance its aesthetics and durability. The existing method of spraying the board surface is mostly to use a control system to control the spraying equipment to perform automated spraying operations on the board, aiming to replace manual labor with intelligent operations, thereby improving production efficiency and spraying quality.

[0003] However, in the process of automatic control of the spraying equipment, the control system needs to control the spraying equipment by manually setting the spraying parameters. In this case, the spraying equipment can only perform spraying operations according to the established parameters set manually, and its autonomous flexibility is greatly reduced. When there is an error between the manually set spraying parameters and the plate to be sprayed, it is difficult for the control system to control the spraying equipment to automatically correct it according to the specific conditions of the plate to be sprayed, which leads to errors in the spraying operation and affects the spraying effect. To this end, we propose an automatic intelligent control system for plate spraying. Summary of the invention

[0004] The purpose of the present invention is to provide an automatic intelligent control system for plate spraying to solve the problems raised by the above-mentioned background technology.

[0005] The object of the present invention can be achieved by the following technical solutions: an intelligent control system for automatic spraying of plate materials, comprising a database, a spraying data preset unit, a correction module, an early warning module, a spraying parameter acquisition unit and a path extraction module;

[0006] A spraying data acquisition unit is used to extract characteristic factors of a plate to be sprayed to form a plate characteristic index, extract characteristic factors of a finished plate after spraying the plate to form a reference characteristic index, obtain corresponding reference spraying process parameters based on the change difference between the characteristic index and the reference characteristic index, match the reference spraying process parameters with preset spraying process parameters, if the match is successful, select the matched reference spraying process parameters as the first spraying parameters, if the match fails, obtain the difference value between the reference spraying process parameters and the preset spraying process parameters, select the mean value of the difference value as the second spraying parameter, and the first spraying parameter and the second spraying parameter together form the spraying index, which is transmitted to the correction module;

[0007] A path extraction module is used to collect the required path for spraying of the spraying plate to be sprayed, obtain a reference spraying path, compare the reference spraying path with a preset spraying path, set the path that is the same as the reference spraying path and the preset spraying path as the first spraying path, re-collect the path where there is a comparison difference between the reference spraying path and the preset spraying path, select the spraying path collected twice and set it as the second spraying path, and the first spraying path and the second spraying path together constitute a spraying guidance path, and transmit it to the correction module;

[0008] The correction module is used to match the received spray index and the preset spray process parameters and the preset spray path corresponding to the spray guidance path. If the match is successful, the spray operation is performed normally according to the spray data. If the match fails, the spray parameters with low values ​​are controlled to be corrected, and the corrected values ​​are marked, the spray guidance path is set as the new spray path, and the spray operation is performed according to the corrected spray data.

[0009] As a further improvement of the present invention, the spraying data preset unit is used to preset spraying parameters to perform the spraying operation, and the specific analysis is as follows:

[0010] The spraying process parameters are preset by manually inputting spraying data or selecting spraying data records from a database. The spraying process parameters specifically include nozzle diameter, spraying distance, spraying speed and spraying pressure. At the same time, the spraying path data is manually inputted or spraying path data records of the same type of plate are selected from a database to complete the preset of the spraying path, and the spraying operation is performed based on the preset spraying parameters and spraying path.

[0011] The parameters of the spraying data, including the nozzle diameter, spraying distance, spraying speed and spraying pressure, are preset as PZ, PJ, PS, and PY respectively. At the same time, the spraying path is preset in the form of a circuit diagram, and the spraying operation is performed based on the preset values ​​and circuits.

[0012] As a further improvement of the present invention, the characteristic factors of the plate to be sprayed are extracted to form a plate characteristic index, and the specific analysis is as follows:

[0013] Image acquisition: Scan the surface of the plate to be sprayed by an image acquisition device, identify its surface features and capture the image, obtain and extract the characteristic factors based on the captured image, and form the plate feature index;

[0014] The surface characteristic factors of the plate may include: whether the surface is smooth, whether there are embossed patterns, etc. If the surface characteristic factors of the plate to be sprayed are rough and have embossed patterns, substitute the formula P1=N1×β1+N2×β2+... to obtain the plate characteristic index P1, where N1, N2... represent the characteristic factors of the plate surface, and β1, β2... represent the set weight factors;

[0015] Scan the surface of the finished plate after spraying by using an image acquisition device, identify its surface features and perform image interception, obtain and extract feature factors based on the intercepted image, and form a reference feature index;

[0016] The surface characteristic factors of the finished plate after spraying may include: whether the surface is smooth, whether there are embossed lines... If the surface characteristic factors of the finished plate are smooth and there are embossed lines, substitute the formula P2 = N1'×β1+N2×β2... to obtain the reference characteristic index P2;

[0017] The plate characteristic index is compared with the reference characteristic index, and the corresponding reference spraying parameters are obtained based on the change difference between the plate characteristic index and the reference characteristic index. The reference spraying parameters are matched with the preset spraying parameters. If the match is successful, the matched reference spraying parameters are set as the first spraying parameters. If the match fails, the parameter difference value between the reference spraying parameters and the preset spraying parameters is obtained, the parameter difference value is averaged, and the average of the parameter difference value and the spraying parameter with a lower value are summed to obtain the second spraying parameter, and the first spraying parameter and the second spraying parameter are substituted into the formula for summation to obtain the spraying index;

[0018] By formula By comparing and selecting the composition indexes with differences in the composition formulas of P1 and P2, the difference between the plate characteristic index and the reference characteristic index can be obtained, that is, the difference value is N1×β1, N1'×β1, indicating that the rough surface of the plate is converted into a smooth surface after spraying. Based on the spraying effect required for the conversion of the rough surface to the smooth surface, the corresponding reference spraying parameters PZ1, PJ1, PS1, and PY1 are obtained;

[0019] Substitute the reference spraying parameters PZ1, PJ1, PS1, PY1 and the preset spraying parameters PZ, PJ, PS, PY into the formula. It indicates that the match is successful, and the matching reference spraying parameters PZ1, PJ1, PS1, and PY1 are substituted into the formula PT1=PZ1×δ1+PJ1×δ2+PS1×δ3+PY1×δ4 to obtain the first spraying parameter PT1, where δ1, δ2, δ3, and δ4 are respectively represented as the set proportional coefficient factors, and the spraying index PT is obtained by the formula PT=PT1+0;

[0020] like It indicates that the matching fails. Substitute the matching reference spraying parameters PZ1 and PJ1 into the formula PT1=PZ1×δ1+PJ1×δ2 to obtain the first spraying parameter PT1. Substitute the unmatched reference spraying parameters PS1 and PY1 into the formula CYZ1=|PS1-PS|, CYZ2=|PY1-PY| to obtain the parameter difference values ​​CYZ1 and CYZ2. The mean of the difference values ​​is calculated to obtain the mean values ​​J1 and J2. If the values ​​of the reference spray parameters PS1 and PY1 are low, the second spray parameter PT2 is obtained by the formula PT2 = (PS1 + J1) × δ3 + (PY1 + J2) × δ4. If the values ​​of the preset spray parameters PS and PY are low, the second spray parameter PT2 is obtained by the formula PT2 = (PS + J1) × δ3 + (PY + J2) × δ4. The first spray parameter PT1 and the second spray parameter PT2 are substituted into the formula PT = PT1 + PT2 to obtain the spray index PT.

[0021] As a further improvement of the present invention, based on the collection of the required spraying path of the spraying plate to be sprayed, a reference spraying path is obtained, and the specific analysis is as follows:

[0022] The surface of the plate to be sprayed is scanned by an image scanning device to obtain the path features of the surface and set it as a reference spraying path, the reference spraying path is compared with the preset spraying path, and the path segments with the same comparison are selected as the first spraying path, and the path segments with different comparisons are subjected to secondary path feature collection on the surface of the plate to be sprayed, and the secondary collected path segments are set as the second spraying path, and the first spraying path and the second spraying path are connected to each other at corresponding positions to form a spraying guide path;

[0023] The surface path features of the plate to be sprayed obtained by image recognition scanning are converted into the composition of a circuit diagram, and the circuit diagram is set as a reference spray path. The circuit diagram of the reference spray path is compared with the circuit diagram of the preset spray path, and the path segments with the same comparison are selected as the first spray path. The path segments with differences in the comparison are subjected to secondary path feature collection on the surface of the plate to be sprayed, and the secondary collected path segments are set as the second spray path. The first spray path and the second spray path are interconnected at corresponding positions to form a spray guidance path circuit diagram.

[0024] As a further improvement of the present invention, based on the correction module, the specific analysis is as follows:

[0025] When there is a difference between the preset spray process parameters input by manual operation and the preset spray path relative to the spray index and the spray guidance path, it indicates that there is an abnormality in the spray data and the spray path. The early warning module can be controlled to issue an early warning to prompt the operator of the abnormal state, and control the spray parameters with low values ​​to correct them, and mark the corrected parameters and values ​​to obtain new spray parameters, perform spray operations based on the new spray parameters, and set the spray guidance path to the new spray path to perform the spray operation.

[0026] The preset spray index PT' is obtained by the formula PT'=PZ×δ1+PJ×δ2+PS×δ3+PY×δ4+0. If PT'≠PT, it indicates that the spray data is abnormal, and the early warning module can be controlled to warn the operator of the abnormal state, and the formula Correction parameters XZ1, XZ2, XZ3, and XZ4 of spraying parameters with low values ​​are obtained, and the spraying parameters with low values ​​are superimposed with the correction parameters for correction to obtain new execution spraying parameters to execute the spraying operation.

[0027] As a further improvement of the present invention, based on the correction module, it also includes an execution terminal, which is used to collect environmental data of the plate spraying operation and analyze it to obtain a ventilation value, and control the operation of the ventilation equipment according to the ventilation value.

[0028] Compared with the prior art, the present invention has the following beneficial effects:

[0029] The present invention manually presets spraying data before executing the spraying operation and autonomously obtains spraying data for the plate to be sprayed, matches the manually preset spraying data with the spraying data acquired through autonomous analysis, obtains new spraying data according to the matching result, and executes the spraying operation according to the new spraying data, thereby avoiding the problem that it is difficult to automatically correct errors in the spraying parameters, thereby affecting the spraying effect.

[0030] The present invention manually presets a spraying path before the spraying operation is performed and autonomously obtains a spraying path for a plate to be sprayed, compares the manually preset spraying path with the spraying path obtained by autonomous analysis, obtains a new spraying path according to the comparison result, and performs the spraying operation through the new spraying path, thereby avoiding the problem that errors in the spraying path are difficult to automatically correct, resulting in errors in the spraying operation;

[0031] The present invention obtains new spray data for executing the spray operation by comprehensively analyzing the manually preset spray data and the autonomously acquired spray data, thereby avoiding the problem of reduced flexibility caused by the traditional spray equipment installing manually set established parameters for spraying operations. It is beneficial to control the spray equipment to automatically correct when operation errors occur, thereby reducing the error phenomenon of the spray operation and further improving the effect of the spray operation. BRIEF DESCRIPTION OF THE DRAWINGS

[0032] In order to facilitate understanding by those skilled in the art, the present invention is further described below with reference to the accompanying drawings.

[0033] Figure 1 is a system block diagram of the present invention;

[0034] Figure 2 This is a schematic diagram of path data processing according to the present invention. DETAILED DESCRIPTION

[0035] The technical solution of the present invention will be clearly and completely described below in conjunction with the embodiments. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0036] Example 1: Please refer to Figure 1 As shown, a plate spraying automatic intelligent control system includes a database, a spraying data preset unit, a correction module, an early warning module, a coating parameter collection unit, a path extraction module and an execution terminal;

[0037] The database is used to store relevant spraying data records of historical plate spraying and the corresponding spraying path diagram, including parameter values ​​of nozzle diameter, spraying distance, spraying speed and spraying pressure corresponding to different plates and required spraying effects, as well as records of the spraying direction path required to achieve the corresponding spraying effect.

[0038] The spraying data preset unit is used to preset spraying parameters to perform spraying operations. The specific analysis is as follows:

[0039] By manually inputting spraying data or selecting spraying data records from the database, the spraying process parameters are preset, and the spraying process parameters specifically include nozzle diameter, spraying distance, spraying speed and spraying pressure. At the same time, by manually inputting spraying path data or selecting spraying path data records of the same type of plate from the database, the spraying path is preset, and the spraying operation is performed based on the preset spraying parameters and spraying path. The size of the nozzle diameter will affect the coarseness of the spray spray. When the nozzle diameter is small, the sprayed spray is delicate, which is suitable for delicate spraying process requirements. When the nozzle diameter is large, the sprayed spray is rough, which is suitable for rough spraying process requirements. The parameters for the nozzle diameter should be selected according to the requirements of plate spraying. The distance of the spraying distance The closer the spraying distance is, the more likely it is that the coating will be unevenly coated. If the spraying distance is too far, the paint will look bad. The parameters for the spraying distance should be selected according to the requirements of the plate spraying. The speed of the spraying will affect the effect of the spraying. If the spraying speed is too fast, it will easily lead to uneven coating thickness. If the spraying speed is too slow, it will easily produce dripping and relief effects. The parameters for the spraying speed should be determined according to the shape and surface requirements of the plate. The size of the spraying pressure will affect the coarseness of the spraying particles. When the spraying pressure is low, fine spray particles can be obtained, which is suitable for the delicate surface coating of the plate. When the spraying pressure is high, it is suitable for the rough surface coating of the plate. The parameters for the spraying pressure should be selected according to the requirements of the plate spraying.

[0040] The parameter values ​​of the preset nozzle diameter, spraying distance, spraying speed and spraying pressure are marked as PZ, PJ, PS and PY respectively; at the same time, the spraying path is preset in the form of a circuit diagram, and the spraying operation is performed based on the preset parameter values ​​and the spraying path in the circuit diagram.

[0041] The spraying data acquisition unit extracts characteristic factors of the plate to be sprayed to form a plate characteristic index, extracts characteristic factors of the finished plate after the plate is sprayed to form a reference characteristic index, obtains corresponding reference spraying process parameters based on the change difference between the characteristic index and the reference characteristic index, matches the reference spraying process parameters with the preset spraying process parameters, and if the match is successful, selects the matching reference spraying process parameters as the first spraying parameters; if the match fails, obtains the difference value between the reference spraying process parameters and the preset spraying process parameters, and selects the mean value of the difference value as the second spraying parameter, and the first spraying parameter and the second spraying parameter together form the spraying index, which is transmitted to the correction module;

[0042] Based on the characteristic factors of the plate to be sprayed, the plate characteristic index is extracted and analyzed as follows:

[0043] Image acquisition: Scan the surface of the plate to be sprayed by an image acquisition device, identify its surface features and capture the image, obtain and extract the characteristic factors based on the captured image, and form the plate feature index;

[0044] The surface characteristic factors of the plate may include: whether the surface is smooth, whether there are embossed patterns, etc. If the surface characteristic factors of the plate to be sprayed are rough and have embossed patterns, substitute the formula P1=N1×β1+N2×β2+... to obtain the plate characteristic index P1, where N1, N2... represent the characteristic factors of the plate surface, and β1, β2... represent the set weight factors;

[0045] Scan the surface of the finished plate after spraying by using an image acquisition device, identify its surface features and perform image interception, obtain and extract feature factors based on the intercepted image, and form a reference feature index;

[0046] The surface characteristic factors of the finished plate after spraying may include: whether the surface is smooth, whether there are embossed lines... If the surface characteristic factors of the finished plate are smooth and there are embossed lines, substitute the formula P2 = N1'×β1+N2×β2... to obtain the reference characteristic index P2;

[0047] The plate characteristic index is compared with the reference characteristic index, and the corresponding reference spraying parameters are obtained based on the change difference between the plate characteristic index and the reference characteristic index. The reference spraying parameters are matched with the preset spraying parameters. If the match is successful, the matched reference spraying parameters are set as the first spraying parameters. If the match fails, the parameter difference value between the reference spraying parameters and the preset spraying parameters is obtained, the parameter difference value is averaged, and the average of the parameter difference value and the spraying parameter with a lower value are summed to obtain the second spraying parameter, and the first spraying parameter and the second spraying parameter are substituted into the formula for summation to obtain the spraying index;

[0048] By formula By comparing and selecting the composition indexes with differences in the composition formulas of P1 and P2, the difference between the plate characteristic index and the reference characteristic index can be obtained, that is, the difference value is N1×β1, N1'×β1, indicating that the rough surface of the plate is converted into a smooth surface after spraying. Based on the spraying effect required for the conversion of the rough surface to the smooth surface, the corresponding reference spraying parameters PZ1, PJ1, PS1, and PY1 are obtained by screening from the database;

[0049] The database stores several types of plate materials, each of which has its corresponding characteristic factors, as well as the spraying effects achieved after the spraying operation. Based on the spraying effects, spraying parameter records during the spraying operation are stored;

[0050] Substitute the reference spraying parameters PZ1, PJ1, PS1, PY1 and the preset spraying parameters PZ, PJ, PS, PY into the formula. It indicates that the match is successful, and the matching reference spraying parameters PZ1, PJ1, PS1, and PY1 are substituted into the formula PT1=PZ1×δ1+PJ1×δ2+PS1×δ3+PY1×δ4 to obtain the first spraying parameter PT1, where δ1, δ2, δ3, and δ4 are respectively represented as the set proportional coefficient factors, and the spraying index PT is obtained by the formula PT=PT1+0;

[0051] like It indicates that the matching fails. Substitute the matching reference spraying parameters PZ1 and PJ1 into the formula PT1=PZ1×δ1+PJ1×δ2 to obtain the first spraying parameter PT1. Substitute the unmatched reference spraying parameters PS1 and PY1 into the formula CYZ1=|PS1-PS, CYZ2=|PY1-PY| to obtain the parameter difference values ​​CYZ1 and CYZ2. The mean of the difference values ​​is calculated to obtain the mean values ​​J1 and J2. If the values ​​of the reference spray parameters PS1 and PY1 are low, the second spray parameter PT2 is obtained by the formula PT2 = (PS1 + J1) × δ3 + (PY1 + J2) × δ4. If the values ​​of the preset spray parameters PS and PY are low, the second spray parameter PT2 is obtained by the formula PT2 = (PS + J1) × δ3 + (PY + J2) × δ4. The first spray parameter PT1 and the second spray parameter PT2 are substituted into the formula PT = PT1 + PT2 to obtain the spray index PT.

[0052] The path extraction module is used to collect the required path for spraying of the spray plate to be sprayed, obtain a reference spraying path, compare the reference spraying path with the preset spraying path, set the path that is the same as the reference spraying path and the preset spraying path as the first spraying path, re-collect the path where there is a difference between the reference spraying path and the preset spraying path, select the spraying path collected twice and set it as the second spraying path, and the first spraying path and the second spraying path together form a spraying guidance path, which is transmitted to the correction module; the specific analysis is as follows:

[0053] An image scanning device is used to perform image recognition scanning on the surface of the plate to be sprayed, and the path features of its surface are obtained and set as a reference spraying path. The reference spraying path is compared with the preset spraying path, and the path segments with the same comparison are selected as the first spraying path. The path segments with different comparisons are subjected to secondary path feature collection on the surface of the plate to be sprayed, and the secondary collected path segments are set as the second spraying path. The first spraying path and the second spraying path are interconnected at corresponding positions to form a spraying guidance path.

[0054] As attached Figure 2 As shown, the surface path features of the plate to be sprayed obtained by image recognition scanning are converted into the composition of a circuit diagram, and the circuit diagram is set as a reference spray path, the circuit diagram of the reference spray path is compared with the circuit diagram of the preset spray path, and the path segments with the same comparison are selected as the first spray path, and the path segments with differences in the comparison are subjected to secondary path feature collection on the surface of the plate to be sprayed, and the secondary collected path segments are set as the second spray path, and the first spray path and the second spray path are interconnected at corresponding positions to form a spray guidance path circuit diagram.

[0055] The correction module is used to match the received spray index with the preset spray process parameters and the preset spray path corresponding to the spray guidance path. If the match is successful, the spray operation is performed normally according to the spray data. If the match fails, the spray parameters with low values ​​are controlled to be corrected, and the corrected values ​​are marked, and the spray guidance path is set as a new spray path. At the same time, according to the corrected spray data, the execution terminal performs the spray operation;

[0056] The specific analysis process of the correction module is as follows: when there is a difference between the preset spraying process parameters input by the manual operation and the preset spraying path relative to the spraying index and the spraying guidance path, it indicates that there is an abnormality in the spraying data and the spraying path, and the early warning module can be controlled to warn the operator of the abnormal state, and control the spraying parameters with low values ​​to correct them, and mark the corrected parameters and values ​​to obtain new spraying parameters, and perform the spraying operation based on the new spraying parameters. At the same time, the spraying guidance path is set as the new spraying path, and the spraying operation is performed by the execution terminal.

[0057] The preset spraying index PT' is obtained by the formula PT'=PZ×δ1+PJ×δ2+PS×δ3+PY×δ4+0. If PT'=PT, it means that the spraying data is normal, and the spraying operation can be performed according to the spraying data. If PT'≠PT, it means that the spraying data is abnormal, and the early warning module can be controlled to warn the operator of the abnormal state, and the formula Obtain correction parameters XZ1, XZ2, XZ3, and XZ4 of spraying parameters with low values, superimpose the correction parameters on the spraying parameters with low values ​​to obtain new execution spraying parameters, and execute the spraying operation by the execution terminal;

[0058] If the spraying parameters with low values ​​are PZ1, PJ1, PS1, PY1 or the spraying parameters with low values ​​are PZ, PJ, PS, PY, then the formula New execution spraying parameters XPT1, XPT2, XPT3, and XPT4 are obtained, and the reference spraying parameters and the preset spraying parameters are replaced by the new execution spraying parameters, and the execution terminal executes the spraying operation.

[0059] Embodiment 2: On the basis of embodiment 1, the execution terminal is also used to collect and analyze environmental data of the plate spraying operation, wherein the environmental data includes temperature, humidity, dust concentration, and the area and height of the corresponding spraying room; the specific analysis process is: setting a number of conditional parameters, and each conditional parameter corresponds to a temperature threshold interval, a humidity threshold interval, and a dust concentration threshold interval, and each conditional parameter corresponds to a spraying parameter range, and the new execution spraying parameters are matched with the spraying parameter ranges corresponding to the several conditional parameters. If they match, the conditional parameters corresponding to the spraying parameter range are matched, and the temperature threshold interval, humidity threshold interval, and dust concentration threshold interval corresponding to the conditional parameters are obtained, and they are marked as temperature standard interval, humidity standard interval, and dust concentration standard interval, respectively;

[0060] The temperature, humidity and dust concentration in the environmental data are compared with the corresponding temperature standard interval, humidity standard interval and dust concentration standard interval respectively. If any of the temperature, humidity and dust concentration in the environmental data is not within the range of the corresponding temperature standard interval, humidity standard interval and dust concentration standard interval, the terminal is executed to control the corresponding equipment to adjust the temperature, humidity and dust concentration until the temperature, humidity and dust concentration in the collected environmental data meet the corresponding temperature standard interval, humidity standard interval and dust concentration standard interval, then the adjustment is stopped, and then the terminal is executed to perform the spraying operation and collect the spraying operation data at the same time. The spraying operation data includes the spraying time data and spraying area of ​​each sprayed plate; the sprayed plate is marked as Bi, i=1, 2, ..., n, n is the total number of sprayed plates; the sprayed plates are divided into several spraying areas and marked as Bij, j=1, 2, ..., m, m is the total number of spraying areas; the initial spraying time and the spraying completion time of each spraying area are obtained, and the intermediate time between the initial spraying time and the spraying completion time is obtained according to the initial spraying time and the spraying completion time (for example, the initial spraying time is 8:30:50, the spraying completion time is 8:30:58, and the intermediate time is 8:30:54), and the time difference between the intermediate time and the current time of the system is calculated to obtain the spraying time of the spraying area and marked as Tij; the area of ​​the spraying area is marked as Mij; the spraying time and the area of ​​the spraying area are normalized and the values ​​are substituted into the formula Output the plate swing value E of the sprayed plate Bi , To is the preset time threshold; the area and height values ​​of the spray booth are marked as MJ1 and GJ2 respectively; substitute the formula Pf = MJ1×μ3+GJ2×μ4 to obtain the total value Pf of the spray booth; normalize the plate volatility values ​​and total values ​​of all sprayed plates in the spray booth, and substitute their values ​​into the general volatility model The total volatility value TEp is obtained, where μ1, μ2, μ3, μ4, μ5 and μ6 are all preset weight factors, and their sizes are customized by technicians according to actual use.

[0061] The ventilation equipment in the spray booth is set to include several operating gears, each operating gear corresponds to a value range, and the ventilation value is matched with several value ranges. If the ventilation value is within the value range, the operating gear corresponding to the value range is marked as the operating gear of the corresponding ventilation equipment in the spray booth. The execution terminal controls the ventilation equipment to operate according to the operating gear, so as to control the environment of the spray booth and avoid too little ventilation in the spray booth, resulting in excessive accumulation of volatile gases from the sheet paint, affecting the health safety of the personnel in the spray booth. At the same time, it can also avoid too much ventilation in the spray booth, resulting in waste of ventilation resources.
