Description

Technical Field

[0001] This invention relates to the field of pig farming technology, and in particular to a method and system for preventing the spread of porcine epidemic diarrhea virus. Background Technology

[0002] Porcine epidemic diarrhea (PED) is a highly contagious intestinal infectious disease caused by coronaviruses. Clinically, it is characterized by vomiting, watery diarrhea, dehydration, and high mortality, especially in newborn piglets, where the mortality rate can reach 80%-100%. It is one of the major diseases currently hindering the healthy development of the pig farming industry. Currently, prevention of PED mainly relies on the following methods: (1) Biosafety measures: Cut off the transmission route through traditional biosafety means such as physical isolation, personnel control, and vehicle disinfection; (2) Vaccine immunization: Herd immunity is achieved by using inactivated or attenuated vaccines, but existing vaccines have problems such as short protection period, insufficient cross-protection and limited protection against variant strains; (3) Drug intervention: Antibiotics are used to control secondary infections, and rehydration salts and antidiarrheal drugs are used for symptomatic treatment, but they cannot effectively eliminate the virus and there is a risk of drug residues; (4) Passive immunization: short-term protection is provided by feeding convalescent pig serum or hyperimmune egg yolk antibodies, but it is costly and poses biosafety risks.

[0003] However, the existing technology system has shortcomings in terms of timeliness and accuracy. Summary of the Invention

[0007] In one implementation, a feeding control instruction for a target pig pen is generated based on the risk period and preset rules, including: if the pig pen is in a decline phase, a severe PED disease feeding program is adopted during a first preset time period, and a moderate PED disease feeding program is adopted after the first preset time period; wherein, the feed-to-water ratio in the severe PED disease feeding program is a first ratio, and the feed-to-water ratio in the moderate PED disease feeding program is a second ratio; if the pig pen is in a recovery phase, a moderate PED disease feeding program is adopted during a second preset time period, and a mild PED disease feeding program is adopted after the second preset time period; wherein, the feed-to-water ratio in the mild PED disease feeding program is a third ratio.

[0008] In one embodiment, before sending the meal control command to the feeding controller corresponding to the target pig pen, the method further includes: generating an early warning message based on the meal control command and sending the early warning message to the staff corresponding to the target pig pen; if a confirmation instruction for the early warning message is received from the staff, then the meal control command is sent to the feeding controller corresponding to the target pig pen.

[0009] In one embodiment, a meal control command is sent to the feeding controller corresponding to the target pig pen so that the feeding controller can dispense feed and water according to the meal control command. This includes: sending the meal control command to the feeding controller corresponding to the target pig pen so that the feeding controller can adjust the amount of feed and water dispensed in the target pig pen based on the meal plan.

[0010] In one embodiment, after the feeding controller adjusts the feed and water supply of the target pig pen based on the meal plan, it further includes: periodically collecting the second total feed intake of the target pig pen; if the second total feed intake is greater than or equal to a preset feed intake value within a continuous preset time period, generating a meal termination instruction; and sending the meal termination instruction to the feeding controller corresponding to the target pig pen, so that the feeding controller feeds feed and water according to a preset water-to-feed ratio.

[0011] Secondly, the present invention provides a system for preventing the spread of porcine epidemic diarrhea virus, comprising: a feed intake data processing module, used to periodically collect the first total feed intake of a target pig pen and generate a feed intake time-series curve of the target pig pen based on the first total feed intake; a control command generation module, used to generate a meal control command for the target pig pen based on preset rules if the total feed intake is continuously decreasing within a preset time period as identified by the feed intake time-series curve; and a control command execution module, used to send the meal control command to the feeding controller corresponding to the target pig pen, so that the feeding controller delivers feed and water according to the meal control command.

[0012] In one implementation, the control instruction generation module is specifically used to: determine the risk period of the pig pen based on the feed intake time-series curve; generate a meal control instruction for the target pig pen based on the risk period and preset rules; wherein the meal control instruction includes: risk period, risk triggering reason and meal plan.

[0015] This invention brings the following beneficial effects: The method and system for preventing the spread of porcine epidemic diarrhea virus (PEDV) provided by this invention first periodically collects the first total feed intake of the target pig pen and generates a time-series curve of feed intake for the target pig pen based on the first total feed intake. If the time-series curve of feed intake indicates that the total feed intake is continuously decreasing within a preset time period, a meal control instruction for the target pig pen is generated based on preset rules. Then, the meal control instruction is sent to the feeding controller corresponding to the target pig pen, so that the feeding controller delivers feed and water according to the meal control instruction. In the above method, a time-series curve of feed intake for the target pig pen can be generated based on the total feed intake, and the risk of porcine epidemic diarrhea can be identified based on the time-series curve of feed intake. When the risk of porcine epidemic diarrhea is detected, corresponding measures are taken, namely, generating a meal control instruction for the target pig pen, so that the feeding controller delivers feed and water according to the meal control instruction, thereby improving the shortcomings of the prior art in terms of timeliness and accuracy.

Detailed Implementation

[0020] To make the objectives, technical solutions, and advantages of the embodiments of the present invention clearer, the technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0021] Currently, the existing PED prevention system has the following shortcomings: (1) Lagging prevention and control: Traditional monitoring methods rely on clinical symptom observation and laboratory testing. By the time an outbreak is discovered, the virus has often already spread widely in the pig herd. (2) Lack of real-time capability: Existing technologies cannot achieve real-time monitoring and early warning of virus spread; (3) Passive intervention: Prevention and control measures are mostly implemented after the outbreak, lacking proactive prevention and early blocking mechanisms; (4) Information silos: There is a lack of effective integration and sharing of epidemic information among farms, veterinary departments and research institutions, making it difficult to form a collaborative prevention and control force; (5) Insufficient accuracy: It is impossible to accurately track the virus transmission path and accurately locate the risk area.

[0022] Based on this, the present invention provides a method and system for preventing the spread of porcine epidemic diarrhea virus, which can improve the shortcomings of the prior art in terms of timeliness, accuracy and synergy.

[0023] To facilitate understanding of this embodiment, a method for preventing the spread of porcine epidemic diarrhea virus disclosed in this embodiment of the invention will first be described in detail. This method can be executed by electronic devices, such as smartphones, computers, and tablets. See also Figure 1 The flowchart shown illustrates a method for preventing the spread of porcine epidemic diarrhea virus, which mainly includes the following steps S101 to S103: Step S101: Collect the first total feed intake of the target pig pen at regular intervals, and generate a time-series curve of feed intake of the target pig pen based on the first total feed intake.

[0024] In one implementation, the system data acquisition module automatically records the first total feed intake of each pig pen (such as fattening pen No. 3) every hour through a smart feeder connected to each pen. The data acquisition module then generates a feed intake time-series curve.

[0025] Step S102: If the total feed intake is continuously decreasing within a preset time period based on the feed intake time-series curve, then a meal control instruction for the target pig pen is generated based on preset rules.

[0026] In one implementation, the pattern recognition module continuously analyzes the feed intake time-series curve. If it detects that the total feed intake is continuously decreasing within a preset time period, it generates a meal control instruction for the target pig pen based on preset rules.

[0027] In practice, the risk period of the pig pen is first determined based on the feed intake time-series curve; then, the feeding control instructions for the target pig pen are generated based on the risk period and preset rules; the feeding control instructions include: risk period, risk triggering reason and feeding plan.

[0028] For example, at a certain point in time, the system detected that the feed intake time-series curve of fattening pen No. 3 dropped sharply from 200 kg per day to 50 kg within 48 hours, and remained at a low level. The curve showed a clear "V" shape with the left half (the decline phase). The system then automatically determined that pen No. 3 had entered a suspected PED risk state, was in the decline phase, and was currently on the third day of the trough. The entire process required no manual review of charts or trend calculations, improving the timeliness and accuracy of risk identification.

[0029] When a suspected risk state of PED is identified, the decision engine is triggered. The decision engine generates feeding control instructions for the target pig pen based on rules in the built-in rule base; the feeding control instructions include: the risk period, the reason for the risk triggering, and the feeding plan.

[0030] Optionally, the system can automatically calculate based on the feed intake time-series curve: if column 3 is in the third day of the decline phase, meeting the conditions for using a heavy meal program from days 1 to 4, the system generates a structured instruction: {Target cell: column 3, Trigger reason: V-shaped feed intake - third day of decline phase: Suggested program: heavy meal program, Planned execution start date: today}, and stores this instruction in the pending task queue. This process is completed automatically by the system within seconds, further improving the timeliness of decision-making.

[0031] Step S103: Send the meal control command to the feeding controller corresponding to the target pig pen so that the feeding controller can deliver feed and water according to the meal control command.

[0032] In one implementation, a meal control command is sent to the feeding controller corresponding to the target pig pen, so that the feeding controller adjusts the feed and water supply of the target pig pen based on the meal plan.

[0033] Specifically, when the system receives a meal control command, the control module retrieves the specific parameters of the meal plan from the meal plan library, such as: water-to-feed ratio mode: water only, no dry feed; duration: maximum 2 days. Subsequently, the system uses the farm's Internet of Things (IoT) to precisely send the meal control command to the corresponding feeding controller in the target pig pen. Upon receiving the command, the feeding controller immediately adjusts the feed dispensing solenoid valve in that pen, while maintaining or increasing the water supply to meet the meal plan specified in the command.

[0034] In this embodiment of the invention, the entire process from instruction confirmation to execution can be completed within minutes, and it only applies to the target pig pen, while the feeding of all other healthy pens remains completely unaffected.

[0035] The method for preventing the spread of porcine epidemic diarrhea virus provided in this embodiment of the invention can generate a time-series curve of feed intake for the target pig pen based on the total feed intake, identify the risk of porcine epidemic diarrhea based on the feed intake time-series curve, and take corresponding measures when the risk of porcine epidemic diarrhea is found, namely, generating a meal control instruction for the target pig pen, so that the feeding controller can deliver feed and water according to the meal control instruction, thereby improving the shortcomings of the prior art in terms of timeliness, accuracy and coordination.

[0036] In one implementation, if V-shaped feeding information is identified based on the feeding intake time-series curve, the corresponding PED meal plan is adopted according to the disease settlement and number of days determined by V-shaped feeding; if V-shaped feeding information is not identified based on the feeding intake time-series curve, the moderate PED meal plan is automatically adopted. If upstream PED is detected positive during the transition period, the severe PED meal plan is automatically implemented; if upstream PED is detected positive during the transition period and the implementation is not completed, the corresponding PED meal plan is automatically implemented.

[0037] Specifically, for the aforementioned step S102, that is, when generating the meal control instructions for the target pig pen based on the risk period and preset rules, the following methods can be adopted, including but not limited to: (1) If the pig pen is in a declining period, a severe PED disease meal plan is adopted during the first preset time period, and a moderate PED disease meal plan is adopted after the first preset time period; wherein, the ratio of feed to water in the severe PED disease meal plan is the first ratio, and the ratio of feed to water in the moderate PED disease meal plan is the second ratio.

[0038] In practice, if the pig pen is in a decline phase, the severe PED disease meal program should be used for days 1-4, and the moderate PED disease meal program should be used after day 5, and so on according to the severity.

[0039] (2) If the pig pen is in the recovery period, a moderate PED disease meal plan shall be adopted during the second preset time period, and a mild PED disease meal plan shall be adopted after the second preset time period; wherein, the ratio of feed to water in the mild PED disease meal plan is the third ratio.

[0040] In practice, if the pig pen is in the recovery period, a moderate PED disease meal plan should be adopted on the first 1-2 days, and a mild PED disease meal plan should be adopted after the 3rd day, and so on according to the severity.

[0041] In this embodiment of the invention, the feeding regimens for severe, moderate, and mild PED diseases differ from normal feeding regimens only in the feed-to-water ratio. The entire feeding period is ≤7 days (2 severe, 3 moderate, 2 mild), and can be manually extended. Specifically, the feed-to-water ratio in the severe PED disease feeding regimen is a first ratio, the ratio in the moderate PED disease feeding regimen is a second ratio, and the ratio in the mild PED disease feeding regimen is a third ratio. The first ratio is less than the second ratio, and the second ratio is less than the third ratio. For example, the severe PED disease feeding regimen may only provide water, without feed, i.e., the first ratio is 0.

[0042] To avoid misjudgment, this embodiment of the invention further includes, before sending the meal control command to the feeding controller corresponding to the target pig pen, generating early warning information based on the meal control command and sending the early warning information to the staff corresponding to the target pig pen; if a confirmation command for the early warning information is received from the staff, then the meal control command is sent to the feeding controller corresponding to the target pig pen.

[0043] In practice, assuming the above-mentioned feeding control instruction is generated in the early morning, the system's timed task scheduler will automatically start at 7:00 AM that day. The message service module will retrieve the feeding control instruction for pen number 3 from the queue and assemble it into an easy-to-read warning message: Warning: Suspected PED risk detected in fattening pen number 3 (V-shaped feeding, day 3 of the decline phase). It is recommended to immediately implement a heavy feeding program. Please confirm. At the same time, this warning message will be pushed to the staff responsible for pen number 3 via WeChat or a dedicated app, including the feeder, the section manager of that area, and the resident veterinarian.

[0044] After receiving the notification tone, the feeder checks the message and, based on the situation (e.g., confirming that the pigs in the pen are indeed lethargic), clicks to confirm execution on the app. If the feeder receives confirmation of the warning information from the staff, the feeding control instruction is sent to the corresponding feeding controller in the target pen. If the feeder finds it to be a false alarm (e.g., the decreased feed intake is simply due to a temporary change in feed), they can click to terminate the instruction.

[0045] In this embodiment of the invention, human supervision is introduced at key decision points to achieve human-machine collaboration, ensuring the reliability and operability of the system's automatic decision-making and preventing unnecessary production interruptions that may be caused by system misjudgment.

[0046] In one embodiment, after the feeding controller adjusts the feed and water supply of the target pig pen based on the meal plan, the above further includes: periodically collecting the second total feed intake of the target pig pen; if the second total feed intake is greater than or equal to a preset feed intake value within a continuous preset time period, generating a meal termination instruction; and sending the meal termination instruction to the feeding controller corresponding to the target pig pen, so that the feeding controller feeds feed and water according to a preset water-to-feed ratio.

[0047] In practice, after adopting the intermittent feeding plan, the system monitoring module will continue to collect the second total feed intake of pen 3 every hour (at this time, only a small amount of water consumption is possible). If, by the evening of the second day, the system detects that the feed intake data of this pen begins to rise and reaches 80% of the normal baseline level (i.e., greater than or equal to the preset feed intake value) for three consecutive hours (i.e., a continuous preset time period), the monitoring module automatically determines that the recovery indicator has met the standard and triggers the termination procedure. The control module generates an intermittent feeding termination command and sends it to the feeding controller corresponding to the target pen, restoring its water-to-feed ratio to the standard fattening period setting (i.e., restoring it to the preset water-to-feed ratio).

[0048] At the same time, the system can automatically generate a detailed intervention report: column 3, PED risk intervention completed, 2 days of heavy fasting, food intake has recovered, automatic termination.

[0049] The method provided in this invention adopts an intelligent closed-loop prevention and control system encompassing monitoring, early warning, confirmation, precise intervention, and monitoring recovery. By accurately identifying V-shaped feeding units or risk units, the intervention scope is precisely locked onto specific pens. Only high-risk targets are subject to a "feed stop but water supply continue" meal plan, thereby reducing the ineffective consumption of veterinary drugs and feed, avoiding production interruption losses, and lowering the cost of epidemic prevention and control. It transforms complex disease prevention and control experience (identifying V-shaped patterns, determining stages, and establishing plans) into automatically running rules and algorithms; simplifies tedious manual operations (pen patrols, recording, and equipment adjustments) into a one-time mobile phone confirmation; and upgrades extensive group management to precise pen-level control, making the prevention and control response more efficient and standardized. Through 24 / 7 automatic monitoring of feed intake curves and intelligent identification of V-shaped feeding patterns, managers no longer need to conduct continuous high-intensity, high-focus clinical inspections, but only need to handle key system prompts, improving the management efficiency and personnel value of pig farms.

[0050] In summary, the embodiments of the present invention, through precise cost control, automated processes, and intelligent management, not only effectively control the spread of PED, but also improve the timeliness and sustainability of disease prevention work in pig farms, thus playing a positive role in promoting the stable production and supply and healthy development of the social pig farming industry.
