Description

Technical Field

[0001] The invention belongs to the technical field of information management, in particular to an electronic information management system and a management method. Background Art

[0002] With the continuous development of the market, in order to adapt to lower cost and higher efficiency breeding results, the pig farming industry is also moving towards scale and automation. The scale of pig farms is getting larger and larger, and a large number of manpower is needed to manage them, which results in a large waste of manpower costs. In addition, the breeding level and work ability of a large number of breeders are different, making it impossible to achieve a scientific and standardized production model of modern production management.

[0003] In the process of pig farming, the quality, temperature, humidity of feed and the amount of exercise of pigs will affect the feed intake of pigs and their healthy growth. By detecting the feed intake and weight changes of pigs, the feed ratio and type in pig farming can be adjusted in time to improve the feed conversion rate, thereby improving the breeding efficiency. In addition, keeping the pigs in a certain amount of exercise can increase their appetite, increase their feed intake, and enhance their physique, ensuring their healthy growth and preventing the occurrence of diseases. At the same time, pigs will have a stress response after being stimulated during the breeding period, which affects their healthy growth. At present, the technology for identifying individual pigs and collecting their feed intake is immature, and it is impossible to obtain the corresponding food intake of a certain pig. Summary of the invention

[0004] In order to make up for the shortcomings of the existing technology, the information data such as the food intake, weight, and exercise volume of the pigs are detected, and the feed input amount and ratio in pig farming are adjusted in a targeted manner to improve the feed conversion rate, reduce the workload of the staff, ensure the healthy growth of the pigs, and improve the farming efficiency. The present invention proposes an electronic information management system and a management method.

[0005] The technical solution adopted by the present invention to solve the technical problem is: an electronic information management system described in the present invention includes a management module, an information collection module and an execution module, the management module analyzes and processes the information uploaded by the information collection module, and the execution module executes the processing solution obtained by the management module, the information collection module includes a camera and a weight sensor installed in a pig house, the camera monitors and photographs each pig in the pig house, the weight sensor is installed in a trough in the pig house, the troughs are independent of each other, and the number of troughs arranged in the pig house is the same as the number of pigs in the pig house;

[0006] The management module includes an analysis unit, a comparison unit and a database. The analysis unit compares and analyzes the video captured by the camera and the data detected by the weight sensor. The analysis unit obtains the food intake and eating time of each pig in the pig house through analysis. The comparison unit compares the food intake and eating time data corresponding to each pig with the previous data of the pig. When the comparison unit finds that the food intake of the pig is reduced and the eating time is prolonged, it is judged that the health of the pig is not good. The database stores the information uploaded by the information collection module, the information obtained by the analysis unit and the comparison unit. The information stored in the database is stored for three months after the pig corresponding to the information is marketed;

[0007] When the comparison unit determines that the health status of the pigs is not good, the execution module sends a health abnormality alarm to the execution module. After receiving the health abnormality alarm, the execution module sends a notification to the staff. After receiving the notification sent by the execution module, the staff goes to the pig house to inspect and process the pigs.

[0008] Preferably, the analysis unit determines that the feed is consumed based on the data sent by the weight sensor and then analyzes the eating time of the pigs. The analysis unit analyzes the eating time of all the pigs in the pig house to obtain the total eating time. The comparison unit compares the total eating time with the total eating time of all the pigs in the pig house to obtain the feed input amount data. When the total eating time becomes shorter, the comparison unit determines that the feed input amount in the pig house is insufficient.

[0009] The execution module includes an automatic feeding device installed in the pig house. The comparison unit sends feed delivery amount data to the execution module, and the execution module adjusts the feed delivery amount of the automatic feeding device each time according to the received data.

[0010] Preferably, the analysis unit analyzes the pigs in the pig house through images taken by a camera to determine the weight of the pigs, and the comparison unit compares the weight of the pigs with the food intake to obtain the feed conversion rate of the pigs.

[0011] Preferably, the management module also includes an identification unit, and the identity information of the staff or temporary visitors is recorded in a database. The identification unit analyzes the video captured by the camera to determine the identity of the person entering the pig house. When the identification unit determines that the identity of the person entering the pig house is unknown, the identification unit issues a stranger alarm. After receiving the stranger alarm, the execution module notifies the staff to promptly ask the stranger to leave the pig house.

[0012] Preferably, the identification unit tracks the staff in the pig house, identifies and analyzes the operations performed by the staff in the pig house, and when the identification unit determines that the staff's operations are in violation of regulations, the identification unit sends an error alarm to the execution module, and the execution module notifies the corresponding staff after receiving the error alarm.

[0013] Preferably, the analysis unit analyzes the movement of the pigs in the pig house through the video captured by the camera, and the analysis unit obtains the amount of movement of each pig through analysis. The comparison unit compares the amount of movement of each pig with the previous amount of movement of the pig. When the comparison unit determines that the amount of movement of the pig is insufficient, it sends a movement alarm message to the execution module;

[0014] After receiving the motion alarm information, the execution module sends a control instruction to the automatic feeding device, and after receiving the control instruction, the automatic feeding device divides the feed into multiple times for delivery.

[0015] Preferably, the automatic feeding device continues to feed the remaining feed after a certain period of time after the pigs have finished eating the feed in the trough, and the automatic feeding device extends the feeding time for the pigs after receiving the control instruction.

[0016] Preferably, the troughs in the pig house do not touch each other, and the automatic feeding device puts the feed into each trough in turn after receiving the control instruction.

[0017] An electronic information management method, the management method is applicable to any of the electronic information management systems described above, the management method comprising the following steps:

[0018] S1: The feed intake of pigs is analyzed and compared through the cameras and weighing sensors installed in the pig house. When the feed intake of pigs changes greatly, the staff is notified to check the pigs, so as to find out the health problems of pigs in time and deal with them. At the same time, by analyzing the time spent by pigs on eating, when feeding the same amount of feed, if the pigs eat for a shorter time, the amount of feed is less, so the staff can adjust the amount of feed in time to avoid feed waste and affect the healthy growth of pigs, thus improving the breeding efficiency.

[0019] S2: Based on S1, the video footage taken by the camera is used to determine the weight of the pigs, and then the feed conversion rate of the pigs is obtained in combination with the feed intake data of the pigs. When the feed conversion rate is low, the staff will promptly check the pigs and adjust the feed ratio to improve the breeding efficiency;

[0020] S3: Based on S1, the images captured by the camera are analyzed to determine the identity of the person entering the pig house and record the person's operations. When a stranger enters the pig house or an employee performs an illegal operation, an alarm is issued in time to avoid affecting the healthy growth of pigs.

[0021] S4: Based on S1, analyze and judge the movement of pigs in the pig house. When it is found that the amount of exercise of pigs is relatively small, mobilize the pigs to do some exercise by adjusting the feeding frequency and using different feeding troughs to increase the feed intake of pigs and improve their physical fitness.

[0022] The beneficial effects of the present invention are as follows:

[0023] 1. The electronic information management system and management method described in the present invention analyzes the pigs in the pig house by setting up an analysis unit and a comparison unit to determine the pigs' food intake, eating time and feed conversion rate, so that the staff can promptly deal with the health status of the pigs, and adjust the amount and ratio of feed to ensure the healthy growth of the pigs, high feed conversion rate, and improve the pig breeding efficiency.

[0024] 2. The electronic information management system and management method described in the present invention can identify people entering the pig house by setting up an identification unit, and promptly notify the staff to ask strangers to leave when they enter the pig house, so as to avoid inducing stress response in pigs and affecting the healthy growth of live pigs. At the same time, the operations of the staff in the pig house are recorded and identified, and the staff's illegal operations are reminded so that the staff can make corrections in time to avoid adverse effects on the pigs in the pig house.

[0025] 2. The electronic information management system and management method described in the present invention, by setting an execution module, an automatic feeding device and separately distributed troughs, when the pigs in the pig house do not exercise enough, the automatic feeding device will divide the feed into multiple times and put it into different troughs in turn, so that the pigs can move back and forth between different troughs during the eating process, thereby increasing the pigs' exercise, enhancing the pigs' physique, and then ensuring the healthy growth of the pigs and improving the breeding efficiency. BRIEF DESCRIPTION OF THE DRAWINGS

[0026] The present invention will be further described below in conjunction with the accompanying drawings.

[0027] Figure 1 is a system block diagram of the present invention;

[0028] Figure 2 It is a flow chart of the method of the present invention. DETAILED DESCRIPTION

[0029] In order to make the technical means, creative features, objectives and effects achieved by the present invention easy to understand, the present invention is further explained below in conjunction with specific implementation methods.

[0030] like Figure 1 and Figure 2 As shown, the electronic information management system described in the present invention includes a management module, an information collection module and an execution module, wherein the management module analyzes and processes the information uploaded by the information collection module, and the execution module executes the processing solution obtained by the management module;

[0031] The information collection module includes a camera and a weight sensor installed in the pig house, the camera monitors and photographs each pig in the pig house, the weight sensor is installed in the trough in the pig house, the troughs are independent of each other, and the number of troughs set in the pig house is the same as the number of pigs in the pig house;

[0032] The management module includes an analysis unit, a comparison unit and a database. The analysis unit compares and analyzes the video captured by the camera and the data detected by the weight sensor. The analysis unit obtains the food intake and eating time of each pig in the pig house through analysis. The comparison unit compares the food intake and eating time data corresponding to each pig with the previous data of the pig. When the comparison unit finds that the food intake of the pig is reduced and the eating time is prolonged, it is judged that the health of the pig is not good. The database stores the information uploaded by the information collection module, the information obtained by the analysis unit and the comparison unit. The information stored in the database is stored for three months after the pig corresponding to the information is marketed;

[0033] When the comparison unit determines that the health status of the pigs is not good, the execution module sends a health abnormality alarm to the execution module. After receiving the health abnormality alarm, the execution module sends a notification to the staff. After receiving the notification sent by the execution module, the staff goes to the pig house to check and process the pigs.

[0034] During the breeding process, pigs are marked, such as with a marker or with a visible ear tag, so that the identity of each pig can be marked when analyzing the image captured by the camera to avoid confusion. At the same time, since the weighing sensor is installed in the trough in the pig house, when the pigs are eating, the food intake of each pig can be accurately determined in conjunction with the recognition of the marks on the pigs. At the same time, as time goes by, the pigs are gradually growing, and their food intake will slowly increase. Therefore, when comparing the food intake of any pig with its previous food intake, the food intake of this pig should be greater than or equal to the previous food intake. At the same time, the pigs will continue to eat until they finish eating the feed in the trough. Therefore, when the amount of feed put in is the same, the eating time of the pigs will be within a fixed range. At the same time, when the pigs' food intake suddenly decreases and the eating time is prolonged, it can be judged that the pigs are in poor health, which affects their appetite, resulting in reduced food intake and prolonged eating time. At this time, the comparison unit sends a health abnormality alarm to the execution module, and then the execution module sends a notification to the staff, so that the staff can go to the pig house in time to check the pigs, treat the pigs or change the environment in the pig house to ensure the healthy growth of the pigs and improve the breeding efficiency.

[0035] At the same time, the staff in the farm carry mobile phones with them. When the execution module sends a notification to the staff, the relevant information is directly sent to the mobile phones carried by the staff so that the staff can receive the notification in time;

[0036] At the same time, a barrier rod is installed at the trough installed in the pig house to block the pigs in the pig house and ensure that when the pigs are eating, one trough corresponds to one pig, avoiding multiple pigs from competing in one trough and affecting the accuracy of the detection data of the weighing sensor.

[0037] As an embodiment of the present invention, the analysis unit determines that the feed is consumed based on the data sent by the weight sensor and then analyzes the eating time of the pigs. The analysis unit analyzes the eating time of all the pigs in the pig house to obtain the total eating time. The comparison unit compares the total eating time with the total eating time of all the pigs in the pig house to obtain the feed input amount data. When the total eating time becomes shorter, the comparison unit determines that the feed input amount in the pig house is insufficient.

[0038] The execution module includes an automatic feeding device installed in the pig house, the comparison unit sends the feed delivery amount data to the execution module, and the execution module adjusts the feed delivery amount of the automatic feeding device each time according to the received data;

[0039] After the pigs in the pig house stop eating, if the weight sensor still detects that there is feed in the trough, it can be judged that too much feed is put into the pig house, resulting in feed waste. Then, the analysis unit sends a prompt message to the execution module, and the execution module adjusts the relevant parameters of the automatic feeding equipment to reduce the amount of feed put in during feeding, avoid feed waste, and increase breeding costs;

[0040] At the same time, when the pigs in the pig house have eaten all the feed in the trough, if the feed is insufficient, the pigs in the pig house will compete with each other when eating and speed up their eating speed so that they can eat more food, thereby shortening the total eating time of all the pigs in the pig house. Therefore, after the comparison unit finds that the total eating time of all the pigs in the pig house is shortened, it can be judged that the amount of feed put into the pig house is insufficient. At this time, the comparison unit sends the information of insufficient feed to the execution module. After that, the execution module controls the automatic feeding equipment in the pig house to increase the amount of feed put into the pig house when putting in the feed, to ensure that the pigs in the pig house can eat enough feed, avoid competition between the pigs in the pig house, make the pigs grow quickly and healthily, and improve the breeding efficiency.

[0041] As an embodiment of the present invention, the analysis unit analyzes the pigs in the pig house through images captured by the camera to determine the weight of the pigs, and the comparison unit compares the weight of the pigs with the food intake to obtain the feed conversion rate of the pigs;

[0042] The analysis unit uses AI to analyze the images captured by the camera to determine the weight of the pigs. There is no need for staff to take the initiative to weigh the pigs, which reduces the workload of staff and avoids manual weighing that may induce stress reactions in pigs, affecting their subsequent healthy growth.

[0043] At the same time, the analysis unit weighs the pigs through the captured images, and can determine the weight of the pigs in time, and timely market the pigs that meet the market standards, to avoid untimely weighing of the pigs, resulting in the pigs being too high or too low in weight when marketed, which affects the breeding benefits;

[0044] At the same time, by timely determining the weight of the pigs and combining it with the pigs' food intake data, the feed conversion rate of the pigs can be effectively obtained, so that when the feed conversion rate is low, the staff can adjust the feed ratio or change the feed type in time, thereby improving the feed conversion rate and improving the breeding efficiency.

[0045] As an embodiment of the present invention, the management module further includes an identification unit, the identity information of the staff or temporary visitor is recorded in a database, the identification unit analyzes the video captured by the camera to determine the identity of the person entering the pig house, and the identification unit issues a stranger alarm when it determines that the identity of the person entering the pig house is unknown, and the execution module notifies the staff to promptly ask the stranger to leave the pig house after receiving the stranger alarm;

[0046] When someone enters the pig house, the recognition unit identifies the person through the image captured by the camera. If the identity of the person entering is unknown, the recognition unit issues a stranger alarm, so that the staff can promptly ask the unknown person to leave the pig house and subsequently clean and disinfect the pig house to prevent unauthorized outsiders from entering the pig house and bringing in foreign germs, which will affect the healthy growth of pigs.

[0047] At the same time, the identification unit can promptly identify outsiders who are not authorized to enter the pig house, thus reducing or avoiding the activities of outsiders in the pig house, thereby reducing the possibility of pigs in the pig house being stimulated by outsiders and inducing stress reactions, thus ensuring the healthy growth of pigs;

[0048] At the same time, since the identity information of staff or temporary visitors is recorded in the database for storage, the number and identity information of people entering the pig house can be accurately recorded under the action of the identification unit, which facilitates the personnel management of the pig house during the pig breeding process and avoids irrelevant personnel entering the pig house, which has an adverse effect on the healthy growth of pigs.

[0049] As an embodiment of the present invention, the identification unit tracks the staff in the pig house, and the identification unit identifies and analyzes the operations performed by the staff in the pig house. When the identification unit determines that the operation of the staff is in violation of regulations, the identification unit sends an error alarm to the execution module, and the execution module sends a notification to the corresponding staff after receiving the error alarm;

[0050] When the staff enters the pig house, the identification unit records and identifies the operations performed by the staff in the pig house in real time. When the staff performs illegal operations, such as not operating in the prescribed order or defaulting to the operation order, the identification unit sends an error alarm to the execution module, which notifies the public staff through the execution module, so that the staff can make corrections in time to avoid the impact of the staff's illegal operations on the healthy growth of pigs;

[0051] At the same time, the operations of the staff in the pig house are recorded in order to judge the work of the staff and trace the source when an accident occurs. At the same time, by identifying and recording the operations of the staff in the pig house, it can also ensure that the staff works seriously in the pig house, avoid the staff being perfunctory, and ensure the healthy growth of the pigs in the pig house.

[0052] As an embodiment of the present invention, the analysis unit analyzes the movement of the pigs in the pig house through the video captured by the camera, and the analysis unit obtains the amount of movement of each pig through analysis, and the comparison unit compares the amount of movement of each pig with the previous amount of movement of the pig, and the comparison unit sends a movement alarm message to the execution module when it determines that the amount of movement of the pig is insufficient;

[0053] After receiving the motion alarm information, the execution module sends a control instruction to the automatic feeding device, and after receiving the control instruction, the automatic feeding device divides the feed into multiple times for delivery;

[0054] During the breeding process, pigs are kept in pig houses, and their daily exercise is relatively small. Less exercise can easily make the pigs have poor physique and become sick, affecting their healthy growth and breeding efficiency. At the same time, the analysis unit analyzes the images taken by the camera to obtain the amount of exercise of each pig in the pig house. When the amount of exercise of the pigs is relatively small, the analysis unit sends a motion alarm message to the execution module, and then the execution module controls the automatic feeding equipment so that the automatic feeding equipment divides the single feed into multiple portions and delivers them multiple times. When the pigs eat, they need to get up and walk to the trough to eat multiple times when the automatic feeding equipment delivers feed multiple times, thereby increasing the amount of exercise of the pigs in the process of getting up and walking to the trough to eat, allowing the pigs to exercise appropriately, improve their appetite, increase their feed intake, and enhance their physique, ensuring their healthy growth and improving breeding efficiency.

[0055] As an embodiment of the present invention, the automatic feeding device continues to feed the remaining feed after a period of time after the pigs have finished eating the feed in the trough, and the automatic feeding device extends the feeding time for the pigs after receiving the control instruction;

[0056] When the automatic feeding device divides the feed into multiple times for delivery, there needs to be a certain interval between two adjacent feed deliveries so that the pigs can return to other places in the pig house to lie down and rest after eating the feed delivered by the automatic feeding device in a single time. Therefore, when the automatic feeding device continues to deliver feed, the pigs need to get up and come to the trough again to eat, ensuring that the pigs exercise appropriately in the process, improving the pigs' physical fitness, and avoiding the automatic feeding device having a short interval between two adjacent feed deliveries, causing the pigs to always stay in front of the trough. When the feed is continued to be delivered, the pigs do not need to exercise too much to continue eating, affecting the effect of guiding the pigs to increase their exercise.

[0057] As an embodiment of the present invention, the troughs in the pig house are not in contact with each other, and the automatic feeding device puts the feed into each trough in turn after receiving the control instruction;

[0058] Furthermore, since the troughs in the pig house do not touch each other, and the automatic feeding equipment puts the feed into different troughs in turn, after the pigs finish eating the feed in the current trough, they must move to other troughs when they eat the feed again, thereby effectively ensuring the effect of increasing the pigs' exercise, enhancing the pigs' physique, ensuring the healthy growth of the pigs, and improving the breeding efficiency.

[0059] An electronic information management method, the management method is applicable to any of the electronic information management systems described above, the management method comprising the following steps:

[0060] S1: The feed intake of pigs is analyzed and compared through the cameras and weighing sensors installed in the pig house. When the feed intake of pigs changes greatly, the staff is notified to check the pigs, so as to find out the health problems of pigs in time and deal with them. At the same time, by analyzing the time spent by pigs on eating, when feeding the same amount of feed, if the pigs eat for a shorter time, the amount of feed is less, so the staff can adjust the amount of feed in time to avoid feed waste and affect the healthy growth of pigs, thus improving the breeding efficiency.

[0061] S2: Based on S1, the video footage taken by the camera is used to determine the weight of the pigs, and then the feed conversion rate of the pigs is obtained in combination with the feed intake data of the pigs. When the feed conversion rate is low, the staff will promptly check the pigs and adjust the feed ratio to improve the breeding efficiency;

[0062] S3: Based on S1, the images captured by the camera are analyzed to determine the identity of the person entering the pig house and record the person's operations. When a stranger enters the pig house or an employee performs an illegal operation, an alarm is issued in time to avoid affecting the healthy growth of pigs.

[0063] S4: Based on S1, analyze and judge the movement of pigs in the pig house. When it is found that the amount of exercise of pigs is relatively small, mobilize the pigs to do some exercise by adjusting the feeding frequency and using different feeding troughs to increase the feed intake of pigs and improve their physical fitness.
