Data transmission method, electronic combination lock device and control method thereof

Abstract

The invention discloses an electronic coded lock device which comprises a RFID (Radio Frequency Identification) control module and an electromechanical lock module. The RFID control module and the electromechanical lock module respectively comprise a storage unit, a communication unit, a checking unit, a first encryption and decryption unit and a second encryption and decryption unit, wherein each storage unit is arranged to store an initial secret key and a communication secret key plaintext; each communication unit is arranged to realize mutual communication between the RFID control module and the electromechanical lock module; each first encryption and decryption unit is arranged to perform a CRC8 (Cyclic Redundancy Check 8) checking algorithm and perform DES (Data Encryption Standard) encryption algorithm for one time; each second encryption and decryption unit is arranged to perform the DES encryption algorithm for multiple times; each checking unit is arranged to check data transmitted between the RFID control module and the electromechanical lock module. The invention further discloses a data transmission method in the electronic coded lock device and a control method of the electronic coded lock device.

Description

technical field [0001] The invention relates to the technical field of electronic combination locks, in particular to a data transmission method for an electronic combination lock device, and also to an electronic combination lock device and a control method thereof. Background technique [0002] At present, the packaging boxes used to transport banknotes are disposable, and the purely mechanical buckles are stuck. When opening the packaging box, the box needs to be destroyed, which is costly and troublesome to open the box. In order to save the cost of currency logistics and achieve intelligence, electronic packaging boxes are used instead of traditional packaging boxes for currency logistics, which can be used multiple times, and authentication is required to open and close the lock to achieve security. The electronic combination lock is provided in the electronic packing box, which is particularly important for the transmission mode of the data in the electronic combinati...
