The invention discloses a preventing and controlling method for a modified swine fever disease. A server is arranged in a server cabinet; the server cabinet comprises a cabinet body; a vertical panelof the cabinet body is subjected to impact molding to form a sealed groove body limited by the vertical panel of the cabinet body, and a through groove is formed in the vertical panel of the cabinet body; a cover plate is hinged to the outer wall of the vertical panel of the cabinet body and covers the through groove; and the server is also used for calculating the number of sensed data packets transmitted by a GPRS communication module. The defects that a substrate management controller is unbearable to tasks increased due to a great number of messages sent to the substrate management controller within short time and the server cannot normally work in the prior art are effectively avoided.
