[0061] Reference Figure 2 , Figure 2 This is a schematic diagram of the steps of the method for spraying oil on fish feed according to an embodiment of the present application. The method for spraying oil on fish feed according to an embodiment of the present application may include but is not limited to the following steps:

[0062] Step S210, obtaining the average feed volume and average feed weight of the fish feed to be sprayed with oil, and obtaining the target oil content;

[0063] In one embodiment, a storage device is provided inside the oil sprayer, and the storage device stores feed specification information, and the feed specification information includes the average feed volume, average feed weight, and target fat ratio of the fish feed to be sprayed with oil. The target fat ratio refers to the ratio of the fat weight in the feed to the total weight of the feed. The average feed volume refers to the average value of the volume of multiple feed particles in the fish feed. The average feed weight refers to the average value of the weight of multiple feed particles in the fish feed.

[0064] Step S220, based on the target fat percentage, average feed weight and average feed volume, determine a target parameter group from a plurality of preset parameter groups; each parameter group includes a reference injection frequency, a reference injection pressure, a reference heating temperature, a reference rotation speed and a reference opening; wherein each parameter group is obtained based on production data of fish feed with qualified fat uniformity;

[0065] In one embodiment, the fuel injector is equipped with a log system, which records the historical data of the fuel injector. The historical data includes multiple groups of production data, each group of production data includes the specification information of the fish feed produced in the history, the equipment parameter information of the fuel injector, and the grease uniformity after fuel injection. The specification information includes the historical average feed volume, the historical average feed weight, and the historical target grease ratio. The equipment parameter information includes the historical fuel injection frequency, the historical fuel injection pressure, the historical heating temperature, the historical rotation speed, and the historical opening of the feed valve. The production data is screened by the grease uniformity after fuel injection, and the production data with grease uniformity lower than the preset uniformity threshold is eliminated. Retain production data with qualified grease uniformity (i.e., production data with grease uniformity greater than a preset uniformity threshold), and from the retained production data, form a parameter group with production data whose log records are greater than a preset record threshold, that is, use the historical injection frequency of the production data as a reference injection frequency, use the historical injection pressure in the production data as a reference injection pressure, use the historical heating temperature in the production data as a reference heating temperature, use the historical rotation speed in the production data as a reference speed, and use the historical opening of the feed valve in the production data as a reference opening. In this way, the preset parameter group can be obtained.

[0066] It should be noted that, since the log records of the production data forming the parameter group are greater than the preset record threshold, the fish feed with specification information in the production data is a more popular feed on the market, is representative, and is more referenceable.

[0067] Step S230, controlling the injection pump based on the reference injection frequency and reference injection pressure of the target parameter group; controlling the heating component based on the reference heating temperature of the target parameter group; controlling the drive motor based on the reference rotation speed of the target parameter group; and controlling the feed valve based on the reference opening of the target parameter group.

[0068] Specifically, in step S230, the pressure of the injection pump is set to a reference injection pressure, the frequency of the injection pump is set to a reference injection frequency, the heating temperature of the heating component is set to a reference heating temperature; the rotation speed of the drive motor is set to a reference rotation speed; and the opening of the feed valve is set to a reference opening.

[0069] The method for spraying oil on fish feed of the embodiment of the present application first obtains the average feed volume and average feed weight of the fish feed to be sprayed with oil, and obtains the target fat percentage, and then determines the target parameter group from multiple preset parameter groups based on the target fat percentage, average feed weight and average feed volume, and then controls the operation of the oil sprayer based on the parameters in the target parameter group. In this way, the operation of the oil sprayer is automatically controlled according to the specification requirements of the fish feed, and there is no need to manually set the parameters of the oil sprayer, which is highly efficient. In addition, each parameter group is obtained based on the production data of fish feed with qualified fat uniformity. Therefore, the operation of the oil sprayer is controlled based on the parameters of the target parameter group, and the fat uniformity of the produced fish feed is also qualified, thereby improving the quality of the feed.

[0070] In one embodiment, each parameter group further includes a reference grease ratio, where the reference grease ratio is a historical target grease ratio in the corresponding production data.

[0071] Step S220, determining a target parameter group from a plurality of preset parameter groups based on the target fat percentage, average feed weight and average feed volume, may include steps S310 to S340.

[0072] Step S310, respectively calculating a first difference between the target fat percentage and the reference fat percentage in each parameter group;

[0073] Step S320, determining a target first difference value with the smallest value from a plurality of first differences;

[0074] Step S330, determining at least one first candidate parameter group from a plurality of parameter groups based on the target first difference;

[0075] Step S340: Detect the first candidate parameter group, and when it is detected that the number of the first candidate parameter group is 1, use the first candidate parameter group as the target parameter group.

[0076] Specifically, the absolute value of the difference between the target fat percentage of the fish feed to be sprayed with oil and the reference fat percentage in the parameter group is calculated as the first difference. The first difference with the smallest value is taken as the target first difference, and the parameter group corresponding to the target first difference is used to determine at least one candidate parameter group. It should be noted that since the reference fat percentage in different parameter groups can be the same, there can be multiple parameter groups corresponding to the target first difference, that is, there are multiple first candidate parameter groups. The absolute value of the difference between the reference fat percentage of each first candidate parameter group and the target fat percentage of the fish feed to be sprayed with oil is the target first difference. When it is detected that the number of first candidate parameter groups is 1, there is no need to perform subsequent steps, and the only first candidate parameter group is taken as the target parameter group.

[0077] In one embodiment, each of the parameter groups further includes a reference volume, which is a historical average feed volume in the production data corresponding to the parameter group.

[0078] After the detection process is performed on the first candidate parameter group, steps S410 to S440 are also included.

[0079] Step S410, when it is detected that the number of the first candidate parameter groups is greater than 1, respectively calculating a second difference between the average feed volume and a reference volume of each first candidate parameter group;

[0080] Step S420, determining a target second difference value with the smallest value from a plurality of second difference values;

[0081] Step S430, determining at least one second candidate parameter group from the first candidate parameter group based on the target second difference;

[0082] Step S440: Detect the second candidate parameter group, and when it is detected that the number of the second candidate parameter group is 1, use the second candidate parameter group as the target parameter group.

[0083] Specifically, when the number of first candidate parameter groups is greater than 1, it is necessary to continue to screen the first candidate parameter groups. Calculate the absolute value of the difference between the average feed volume of the fish feed to be sprayed with oil and the reference volume in each first candidate parameter group as the second difference. Take the second difference with the smallest value as the target second difference, and take the first candidate parameter group corresponding to the target second difference as the second candidate parameter group. It should be noted that since the reference volumes in different parameter groups can be the same, there can be multiple first candidate parameter groups corresponding to the target second difference, that is, there can be multiple second candidate parameter groups. The absolute value of the difference between the reference volume of each second candidate parameter group and the average feed volume of the fish feed to be sprayed with oil is the target second difference. When it is detected that the number of second candidate parameter groups is 1, there is no need to perform subsequent steps, and the only second candidate parameter group is taken as the target parameter group.

[0084] In one embodiment, each parameter group further includes a reference weight, which is a historical average feed weight in the production data corresponding to the parameter group.

[0085] After the second candidate parameter group is detected, the method further includes steps S510 to S540.

[0086] Step S510, when it is detected that the number of the second candidate parameter groups is greater than 1, respectively calculating a third difference between the average feed weight and the reference volume of each second candidate parameter group;

[0087] Step S520, determining a target third difference value with the smallest value from a plurality of third differences;

[0088] Step S530, determining at least one third candidate parameter group from the second candidate parameter group based on the target third difference;

[0089] Step S540: determine a target parameter group from the third candidate parameter group.

[0090] Specifically, when the number of the second candidate parameter groups is greater than 1, the second candidate parameter groups need to be screened further. The absolute value of the difference between the average feed weight of the fish feed to be sprayed with oil and the reference weight in each second candidate parameter group is calculated as the third difference. The third difference with the smallest value is taken as the target third difference, and the second candidate parameter group corresponding to the target third difference is taken as the third candidate parameter group.

[0091] Step S540 may include the following steps:

[0092] Performing detection processing on the third candidate parameter group;

[0093] When it is detected that the number of the third candidate parameter groups is 1, the third candidate parameter group is used as the target parameter group.

[0094] In some embodiments, the fish feed oil spraying method of the present application embodiment further includes the following steps after step S220:

[0095] Step S610, recording the number of times each parameter group is selected as the target parameter group;

[0096] Step S620, saving the number of times each parameter group is selected into a preset database.

[0097] In another embodiment, step S540 may include the following steps:

[0098] Step S710, when it is detected that the number of third candidate parameter groups is greater than 1, obtaining the number of times each third candidate parameter group is selected from a preset database;

[0099] Step S720: taking the third candidate parameter group with the largest number of selections as the target parameter group.

[0100] Through step S710 to step S720, the third candidate parameter group with the largest number of selections is used as the target parameter group. The largest number of selections indicates that the corresponding feed specification is the most in line with market preferences among multiple third candidate parameter groups. Therefore, the third candidate parameter group with the largest number of selections is used as the target parameter group, which can make the produced feed have a greater probability of meeting market preferences.

[0101] The second aspect of the present application provides a fish feed oil spraying device, which is applied to Figure 1 Schematic diagram of the fuel injection machine. Figure 3 , Figure 3 This is a schematic diagram of the structure of the fish feed oil spraying device of the embodiment of the present application. The device includes:

[0102] The acquisition module 310 is used to obtain the average feed volume and average feed weight of the fish feed to be sprayed with oil, and obtain the target oil content;

[0105] The fish feed oil spraying device of the embodiment of the present application is used to execute the fish feed oil spraying method of the first aspect of the embodiment of the present application. When executing the method, the average feed volume and average feed weight of the fish feed to be sprayed with oil are first obtained, and the target fat ratio is obtained. Then, based on the target fat ratio, the average feed weight and the average feed volume, the target parameter group is determined from multiple preset parameter groups, and then the operation of the oil sprayer is controlled based on the parameters in the target parameter group. In this way, the operation of the oil sprayer is automatically controlled according to the specification requirements of the fish feed, and there is no need to manually set the parameters of the oil sprayer, which is highly efficient. In addition, each parameter group is obtained based on the production data of fish feed with qualified fat uniformity. Therefore, the operation of the oil sprayer is controlled based on the parameters of the target parameter group, and the fat uniformity of the produced fish feed is also qualified, thereby improving the feed quality.
