A device control method, comprising: receiving a request for exclusive control from a first control device, and entering an exclusive mode; receiving a first access request; within valid time of the exclusive mode, judging whether the first access request is an access request sent by the first control device; if yes, executing the first access request; and otherwise, directly rejecting or discarding the first access request; and receiving a second access request from a second control device; the method characterized in that the request for exclusive control from the first control device comprises exclusion condition information including exclusive access interface information; and in that the method further comprises: determining an interface requested to be accessed by the second access request; and in the case where the exclusive access interface information indicates an interface that is allowed to be accessed, executing the second access request in the event the interface is included in the exclusive access interface information, or rejecting the second access request in the event the interface is not included in the exclusive access interface information; or in the case where the exclusive access interface information indicates an interface that is forbidden to be accessed, rejecting the second access request in the event the interface is included in the exclusive access interface information, or allowing the second access request in the event the interface is not included in the exclusive access interface information. receiving a request for exclusive control from a first control device, and entering an exclusive mode; receiving a first access request; within valid time of the exclusive mode, judging whether the first access request is an access request sent by the first control device; if yes, executing the first access request; and otherwise, directly rejecting or discarding the first access request; and receiving a second access request from a second control device; the method characterized in that the request for exclusive control from the first control device comprises exclusion condition information including exclusive access interface information; and in that the method further comprises: determining an interface requested to be accessed by the second access request; and in the case where the exclusive access interface information indicates an interface that is allowed to be accessed, executing the second access request in the event the interface is included in the exclusive access interface information, or rejecting the second access request in the event the interface is not included in the exclusive access interface information; or in the case where the exclusive access interface information indicates an interface that is forbidden to be accessed, rejecting the second access request in the event the interface is included in the exclusive access interface information, or allowing the second access request in the event the interface is not included in the exclusive access interface information. determining an interface requested to be accessed by the second access request; and in the case where the exclusive access interface information indicates an interface that is allowed to be accessed, executing the second access request in the event the interface is included in the exclusive access interface information, or rejecting the second access request in the event the interface is not included in the exclusive access interface information; or in the case where the exclusive access interface information indicates an interface that is forbidden to be accessed, rejecting the second access request in the event the interface is included in the exclusive access interface information, or allowing the second access request in the event the interface is not included in the exclusive access interface information. <EOS>
