Patent ID: 7634658

Claim:
A method for logical binding and verifying subassembly in equipment, comprising: setting one or more subassemblies in the equipment as one or more sub-modules, and setting a main module in the equipment, each of the one or more sub-modules storing individual information of its own and the main module storing the individual information of the one or more sub-modules; setting an identifier for each sub-module to identify the corresponding sub-module; and the main module obtaining verification information corresponding to individual information of a first sub-module of the one or more sub-modules stored in the main module and sending the verification information to the first sub-module when the first sub-module needs to be verified, the main module storing a corresponding relationship between the individual information of the one or more sub-modules and the identifiers of the one or more sub-modules; wherein the step of the main module sending the verification information to the sub-module comprises: the main module determining the individual information of the sub-module among the individual information of the one or more sub-modules according to the corresponding relationship, and obtaining the verification information corresponding to the individual information of the sub-module and sending the verification information to the sub-module corresponding to the identifier of the sub-module; the first sub-module judging whether the received verification information matches the individual information of its own stored in the first sub-module itself after receiving the verification information from the main module, if the received verification information matches the individual information stored in the first sub-module itself, the sub-module operating normally; otherwise, the first sub-module stopping operating; setting individual information of the main module in the main module; and before the main module sending to the first sub-module the verification information corresponding to the individual information of the first sub-module, receiving, through an input unit of the equipment or verification equipment outside this equipment, verification information corresponding to the individual information of the main module, and the main module judging whether the received verification information matches the individual information of the main module; if the received verification information matches the individual information of the main module, the main module sending to the first sub-module the verification information corresponding to the individual information of the first sub-module; if the received verification information does not match the individual information of the main module, the main module stopping operating.
