[0021] In one specific embodiment, the specific process of setting up the monitoring areas for the target poultry and livestock is as follows: Poultry and livestock distribution data is obtained from the database. This data includes the breeding density and quantity of target poultry and livestock at each breeding center. If the breeding density of target poultry and livestock at a certain breeding center is greater than the preset standard breeding density, or the quantity of target poultry and livestock is greater than the preset standard quantity, that breeding center is designated as the infection monitoring center for the target poultry and livestock. This process is used to obtain the infection monitoring centers for the target poultry and livestock. The infection distances of the target poultry and livestock at each stage are obtained from the database. The average value of these infection distances is calculated to obtain the standard infection distance for the target poultry and livestock. A circle is drawn with the center of each infection monitoring center for the target poultry and livestock as the center and the standard infection distance of the target poultry and livestock as the radius. The area within this circle is the monitoring area for the target poultry and livestock.

[0022] In one specific embodiment, the infectious data of each monitoring area of the target poultry is collected, and the collection process is as follows: the number of target poultry is identified by a camera to obtain the number of poultry in each monitoring area, and the activity distance of each poultry in a preset time period is collected, if the activity distance of a certain poultry is less than a preset value, the poultry is recorded as an abnormal poultry, and thus the number of abnormal poultry in each monitoring area is obtained, the number of abnormal poultry in each monitoring area is divided by the number of target poultry to obtain the abnormal rate of poultry in each monitoring area, and the number of abnormal death of poultry is input by the staff to obtain the number of dead poultry in each monitoring area, and the number of dead poultry in each monitoring area is divided by the number of poultry to obtain the mortality rate of poultry in each monitoring area.

[0023] It should be noted that the abnormal death is the death caused by epidemic, such as avian influenza.

[0024] Step two, infectious source information analysis: according to the area infection model, the infectious data of each monitoring area of the target poultry is analyzed to obtain each infectious area of the target poultry and the infection level of each infectious area, the area information of each infectious area of the target poultry is obtained from the database, the infection type of each infectious area of the target poultry is judged according to the area information of each infectious area of the target poultry, and thus the infection source and transmission route of the target poultry are obtained, and a blocking scheme is set.

[0025] In one specific embodiment, the infectious data of each monitoring area of the target poultry is analyzed, and the specific analysis process is as follows: the infectious data of each monitoring area of the target poultry includes the abnormal rate and mortality rate of poultry in each monitoring area of the target poultry, the infectious data of each monitoring area of the target poultry is input into the area infection model to obtain the output result of each monitoring area of the target poultry, and the output result is , .

[0026] If the output result of a certain monitoring area of the target poultry is equal to 0, it indicates that the monitoring area is a non-infectious area, and if the output result of a certain monitoring area of the target poultry is greater than 0, it indicates that the monitoring area is an infectious area, and thus each infectious area of the target poultry is obtained.

[0027] If the output result of a certain infectious area of the target poultry is equal to 1, the infection level of the infectious area is recorded as level 1, if the output result of a certain infectious area of the target poultry is equal to 2, the infection level of the infectious area is recorded as level 2, if the output result of a certain infectious area of the target poultry is equal to n, the infection level of the infectious area is recorded as level n, n is the maximum level of the infection level, and the number of the infection level is g, , , and thus the infection level of each infectious area of the target poultry is obtained.

When the abnormal rate of a certain risk area is greater than the corresponding standard abnormal rate or the mortality rate is greater than the corresponding standard mortality rate, the staff of the risk area are prompted, and the infection distance corresponding to the target infection channel is obtained from the database. Make a circle with the center position of the risk area and the infection distance as the radius to obtain the propagation area of the risk area, and give early warning to other monitoring areas in the propagation area.

9. An analysis system of infection source based on distribution of poultry animals according to any one of claims 1 to 8, characterized by, The following modules are included: The infection source information acquisition module is used to set each monitoring area of the target poultry according to the target poultry distribution data in the database, and to collect the infection data of each monitoring area of the target poultry; The infection source information analysis module is used to analyze the infection data of each monitoring area of the target poultry according to the area infection model, obtain each infection area and the infection level of each infection area of the target poultry, obtain the area information of each infection area of the target poultry from the database, judge the infection type of each infection area of the target poultry according to the area information of each infection area of the target poultry, and obtain the infection source and transmission path of the target poultry, and then set the blocking scheme; The livestock infectious disease prevention module is used for obtaining risk data of target livestock from an infectious source and a transmission route of the target livestock after implementing a blocking scheme, analyzing the risk data of the target livestock according to a regional risk model, obtaining each risk region and a risk level of each risk region of the target livestock, and then setting a monitoring scheme for collecting risk region infectious data of the target livestock and performing early warning according to the risk region infectious data of the target livestock.
