In order to facilitate understanding of the technical solutions provided by the embodiments of the present invention, the following detailed description is given with reference to embodiments of specific application scenarios.
In the embodiment, the activity track of the virus carrying source is recorded, so that the virus risk is controllable and can be accurately blocked. As shown in fig. 2, the method provided by this embodiment mainly includes the following steps:
step S201, dividing the farm into 4 layer areas: an external field area, a safety boundary area, an isolation area and an internal field area.
Step S202, entering the internal field area from the external field area, needing to pass through the safety boundary area first, performing sampling detection in the safety boundary area, and entering the internal field area after the detection is passed. If an anomaly is detected, the isolation zone is entered.
