The method includes: generating and sending a control command to a flat panel detector in response to an operation instruction of a user (101); receiving actual response identification information sent by the flat panel detector when the flat panel detector determines that the control command is a first type of control command (102); and verifying the consistency of the actual response identification information and pre-stored expected response identification information, and generating prompt information (103). ## Claims ### Claim 1 A method for controlling a flat panel detector, comprising: 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. ### Claim 2 (depends on 1) The method according to claim 1, wherein the determining the control command to be the first type of control command comprises: judging whether the control command comprises a first type of flag, and in response to determining that the control command comprises the first type of flag, determining that the control command is the first type of control command. ### Claim 3 (depends on 1) The method according to claim 1, wherein the verifying the consistency of the actual response identification information and the expected response identification information comprises: reading the actual response identification information sequentially from a receive event queue, wherein the receive event queue is used for storing the actual response identification information fed back by the flat panel detector; controlling a count value to be increased by one in response to determining that the read actual response identification information is the same as one of the expected response identification information; and judging whether a numerical value of the count value is the same as a quantity of the expected response identification information in the expected event queue or not. ### Claim 4 (depends on 3) The method according to claim 3, wherein the generating the prompt information comprises: generating parameter setting success prompt information in response to determining that the actual response identification information is consistent with the expected response identification information; and generating parameter setting failure information and failure reason prompt information in response to determining that the actual response identification information is inconsistent with the expected response identification information. ### Claim 5 (depends on 1) The method according to claim 1, wherein the receiving the 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 comprises: entering a receiving thread in response to determining that the control command is the first type of control command; judging whether a buffer is empty or not cyclically for multiple times; extracting a feedback control command sent by the flat panel detector from the buffer in response to determining that the buffer is not empty in the current judgment process, wherein the feedback control command comprises a corresponding flag and the actual response identification information; and adding the actual response identification information in the feedback control command into a receive event queue in response to determining that the corresponding flag in the feedback control command is a first type of flag. ### Claim 6 (depends on 5) The method according to claim 5, wherein the receiving the 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 further comprises: ending the receiving thread in response to determining that the buffer is empty in the current judgment process. ### Claim 7 (depends on 1) The method according to claim 1, wherein after the receiving the 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 before the verifying the consistency of the actual response identification information and the expected response identification information, the method further comprises: judging whether a quantity of the received actual response identification information is not less than a quantity of the expected response identification information or not. ### Claim 8 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. ### Claim 9 (depends on 8) A flat panel detector, comprising a second processing component, wherein the second processing component is used for executing the method according to claim 8. ### Claim 10 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.
