in the embodiment of the invention, the equipment lock can judge whether the equipment lock is allowed to be operated according to whether the identification number of the equipment lock is included in the operation object information, if so, the operation object information is utilized to intercept the operation content information ciphertext corresponding to the equipment lock from all the operation content information ciphertexts related to the operation ticket, and then, the private key stored by the equipment lock is utilized to decrypt the operation content information ciphertext.
In step S304, corresponding device operations are performed according to the operation content information corresponding to the device lock.
In the embodiment of the invention, when the anti-misoperation key is used for operating the equipment lock, the equipment lock identifies the information code on the anti-misoperation key through the information code identification module to obtain all operation content information ciphertexts and the UID of the electronic tag contained in the information code, reads the UID of the electronic tag of the anti-misoperation key through the second tag reading and writing module, then compares the UID obtained by identification with the read UID, reads the operation object information ciphertexts in the electronic tag if the information ciphertexts are the same, judges whether the equipment lock is allowed to be operated according to the operation object information, if so, intercepts and decrypts the operation content information ciphertexts corresponding to the equipment lock in all the operation content information ciphertexts by using the operation object information, further executes corresponding equipment operation according to the operation content information corresponding to the equipment lock, thereby realizing the anti-misoperation of the equipment, simplifying the use and maintenance process of the anti-misoperation system, the use safety and the management and control efficiency of the anti-misoperation key are improved.
The above description is only for the purpose of illustrating the preferred embodiments of the present invention and is not to be construed as limiting the invention, and any modifications, equivalents and improvements made within the spirit and principle of the present invention are intended to be included within the scope of the present invention.
