The application provides a detection device for a function keyboard controller of a linear accelerator, which comprises a first pin and a power supply connection, a twenty-fifth pin, a first resistor, a first LED lamp and a ground connected in sequence, and a first key. If the first LED lamp is lighted when the first key is pressed, it is determined that the first key and the first contact group are normal. The thirty-second pin of a connector is connected with a first relay coil and a ground in sequence, the thirty-fourth pin of the connector is connected with a first relay contact and a ground in sequence, and the first pin, the twenty-fifth pin, the thirty-second pin and the thirty-fourth pin are connected with corresponding pins with the same name in the function keyboard controller. When the ninth key and the tenth key are pressed, the first display lamp on the function keyboard controller is lighted and the second display lamp is extinguished. When the ninth key is disconnected, the first display lamp is lighted and the second display lamp is extinguished. When the tenth key is disconnected, the first display lamp is extinguished and the second display lamp is lighted. It is determined that the ninth key and the tenth key are normal. Maintenance personnel can intuitively determine the location of the fault.

The embodiment of the present application provides a keyboard controller style interface fault redundancy method and device, relates to the field of servers, and comprises the following steps: solidifying keyboard controller style interface information to flash memory; obtaining digital integrated circuit mapping information when a basic input output system starts; determining a baseboard management controller state according to the digital integrated circuit mapping information; when the baseboard management controller state is abnormal, repeatedly executing the step of obtaining the digital integrated circuit mapping information after a preset time interval until a first repetition number is reached, repeatedly executing the step of sending a baseboard management controller state detection instruction to detect the baseboard management controller state until a second repetition number is reached, and creating a keyboard controller style interface according to the keyboard controller style interface information stored in the flash memory; and the embodiment of the present application can improve the reliability and stability of a server system.
