For a variety of acousto-optic hint information including system low-voltage alarm, switch gate prompt and system communication mistake etc., guest is promoted
Facilitate management and technical staff while experience to the judgement of the normal or abnormal working condition of door lock, is conducive to the later period dimension of door lock
Shield.
Preferably, Clock management chip is omitted in master board, it is fixed using the on piece of system crystal oscillating circuit and main control chip
When device timing, cooperate multiple clock calibrating mode calibrating terminal system clock, reduce system hardware cost.
Preferably, re-powering appearance for the work of system master prolonged periods caused by Crystal Oscillator Errors or system
Clock is inaccurate, according to different unlocking modes, using the respective alignment method calibration system time.It unlocks when using Mifare card
When, special clock setting card, periodic calibration system clock can be set；It, will be objective when being unlocked using intelligent mobile phone Bluetooth function
The manpower machine system and Internet time is transmitted to main control chip by bluetooth communication, realizes the accurate calibration of terminal clock；It uses
When smart phone NFC function is unlocked, main control chip receives the system time data that guest's mobile phone is passed back, equally being capable of accurate calibration
Terminal system clock.Above-mentioned three kinds of calibration methods can ensure that the accurate of system time with cross-reference.
Preferably, dedicated encryption and decryption calibrating chip is omitted, using specific complex logic mathematical algorithm to transmission data
Encryption.For door lock terminal, main control chip decrypts the data received, while the data encryption to be sent using inverse logic；
For mobile phone terminal, application program of mobile phone decrypts the received data of mobile phone using inverse logic, while the data encryption to be sent.
Using this mode, hardware cost is reduced first, secondly, door lock terminal is not necessarily to connect server by gateway, eliminates complexity
Key authorization and management process, when using Bluetooth of mobile phone and when mobile phone NFC communication, using identical communication number inside Mifare
According to pack arrangement and identical enciphering and deciphering algorithm, the uniformity of system ensure that.
Preferably, using the encryption of programming port hardware and two kinds of cipher modes of Bootstrap loader superencipherment to master
Chip encryption is controlled, guarantees the safety of Terminal driving software.
Preferably, being encrypted using authorization code mode to door lock mainboard, the internal particular sector key of cooperation Mifare card is prevented
Only door lock is initialized as other hotel's door locks by others, improves the safety of system.
Preferably, being implemented in combination with the storage of guest's enabling information using a variety of storage modes.Selected terminal main control chip can
To store a large amount of guest's unlocking information.When using smart card unlocking mode, for guest while unlocking, terminal unlocks guest
Information and the storage of lockset status information are used as backup into main control chip data space, meanwhile, mould is communicated by NFC data
Block will store information back into Mifare card data storage sector, and data acquisition Mifare card can be used when necessary and adopt
Data are read into server storage tube by the unlocking data backed up in collection terminal main control chip, the hotel Zai You based terminal system
Reason；When being unlocked using Bluetooth of mobile phone communication mode, mobile phone terminal application program is connected by cell phone network and hotel management database
It connects, after mobile phone terminal establishes connection with door lock terminal, mobile phone terminal sends unlocking instruction, when door lock terminal tests guest's check-in information
Card is unlocked after passing through, while sending mobile phone by bluetooth module for unlocking information and lockset status information, and mobile phone passes through network
Data back to hotel management terminal server, same terminal main control chip are stored backup information by connection；As use mobile phone NFC
When mode is unlocked, mobile phone terminal application program is connect by cell phone network with hotel management database, when mobile phone terminal and door lock terminal
After establishing connection, mobile phone NFC analog card is written in guest's check-in information by mobile phone terminal application program, when guest's mobile phone is close to door lock end
When end, door lock terminal reads guest's check-in information inside mobile phone NFC analog card, verifies and leads to guest's check-in information when door lock terminal
Later it unlocks, while unlocking information and lockset status information is written back to mobile phone NFC analog card, mobile phone by NFC communication module
By network connection by data back to hotel management terminal server, same terminal main control chip stores backup information.
With reference to the accompanying drawing and specific embodiment is described further technical solution of the present invention.
