a computer key

Abstract

The invention provides a computer key. The computer key comprises a key body, a code reading probe, a de-locking mechanism and a built-in circuit; the built-in circuit comprises a core control circuit, a lockset type judging circuit, an RFID code reading circuit, an intelligent code reading circuit and a communication circuit; during use, on the basis of a judged result obtained by the lockset type judging circuit, code reading is performed on locksets to be operated; the de-locking mechanism comprises a positioning pin, a de-locking pin and an unlock button, wherein on one hand, the positioning pin has a positioning function, and on the other hand, the positioning pin can be used as an electrode for de-locking an electrical locking circuit; the de-locking pin is used for de-locking locksets of mechanical locks, and besides, the de-locking pin can be used as the other electrode for de-locking the electrical locking circuit. The computer key provided by the invention is compatible with traditional keys for de-locking various locksets encoded with RFID, and besides, the computer key can supply power to an intelligent lockset or intelligent equipment; in addition, through the computer key, the intelligent lockset can be de-locked and information in the intelligent equipment can be achieved in the manner of mutually transmitting information. The situation that the number of keys for a wrong-operation preventing system is greatly reduced is ensured, and the performance of the wrong-operation preventing system is improved.

Description

Technical field [0001] The invention relates to the technical field of safety and misuse prevention locking equipment in industrial occasions such as substations, power plants, and outdoor equipment in distribution networks, and in particular to a computer key used in the field of power misuse prevention and safety. Background technique [0002] At present, the computer keys used in the electric power error prevention system are mainly used to open ordinary locks for management, such as figure 1 with Figure 4 It has a key body, a code reading probe, an unlocking mechanism and a built-in circuit. The built-in circuit includes an RFID code reading circuit 14, a core control circuit 15 and other circuits 16. The circuit board 13 on the code reading probe contains an induction coil 12. The computer key can only unlock the traditional RFID coded lock. When the computer key is inserted into the matching lock, the computer key activates the RFID code reading circuit and reads the RFID c...

AI Technical Summary

Problems solved by technology

The existing computer keys for electric power error prevention cannot unlock both traditional locks and smart locks. Therefore, one key corresponds to one lock. In actual use, there are many keys, which are difficult to identify and cannot be used effectively. The performance of the traditional error prevention system urgently needs to be greatly improved.
