Method for controlling flat panel detector, and upper computer, flat panel detector and medical system

A method for controlling a flat panel detector, comprising:

• receiving a control command sent by an upper computer;
• and
• judging whether the control command comprises a first type of flag or not, and in response to determining that the control command comprises the first type of flag, determining that the control command is a first type of control command;
• generating a feedback control command comprising a corresponding flag and actual response identification information;
• and
• sending the feedback control command to the upper computer.

An upper computer, comprising a first processing component, wherein the first processing component is used for executing:

• generating a control command in response to an operation instruction of a user;
• generating an expected response identification information corresponding to the control command in response to determining that the control command is a first type of control command;
• storing the expected response identification information to an expected event queue;
• sending the control command to the flat panel detector;
• receiving actual response identification information sent by the flat panel detector when the flat panel detector determines that the control command is the first type of control command;
• and
• verifying consistency of the actual response identification information and the expected response identification information, and generating prompt information.
