The invention discloses a work order management-based intelligent lockset system for a wiring terminal box. The work order management-based intelligent lockset system is provided with a passive lock body, a power-supplying handle, a mobile communication terminal and a management information system server. The power-supplying handle supplies power to the passive lock body in an electromagnetic induction manner; the mobile communication terminal transmits a received task order containing an electronic key to the passive lock body by using a Bluetooth communication link, and the passive lock body can verify the received electronic key so as to determine whether to unlock the box; and after unlocking by the passive lock body, the power-supplying handle is used for turn a lock pin of the passive lock body so as to open the passive lock body. According to the invention, a power supply is not needed for the wiring terminal box on which the passive lock body is installed and the passive lock body can be unlocked by using the electronic key; so the wiring terminal box becomes a control object of a information management system, problems in management of keys are overcome, and the work order management-based intelligent lockset system has the advantage of convenience in usage.
