[detailed description of the invention]
As shown in Figure 1, be an embodiment the coded lock based on radio communication control method flow diagram.The method of the present embodiment is used for being unblanked and lock-in control to coded lock by secret key terminal in the coding lock system comprising secret key terminal and coded lock, specifically comprises the following steps:
Step S110, coded lock upgrades according to predetermined period and pre-defined algorithm and stores opens secret key.
Coded lock is the mechanical lock with control module, and control module is when verifying that secret key of unblanking is consistent with the unlatching secret key of coded lock storage inside, and instruction mechanical lock is unblanked.Store pre-defined algorithm in control module, and preset the time of pre-defined algorithm generation unlatching secret key, namely coded lock can upgrade unlatching secret key by predetermined period with pre-defined algorithm.Pre-defined algorithm and secret key generating algorithm, be generate the mode of opening secret key, pre-defined algorithm can generate different unlatching secret keys.Predetermined period is unlatching secret key cycle rise time that user is arranged, and such as, it is 24 hours that user arranges predetermined period, and so pre-defined algorithm was then just generating new unlatching secret key every 24 hours.
Secret key terminal is equivalent to the key opening coded lock.After setting up synchronous communication between secret key terminal palpus and coded lock, secret key terminal can generate according to the pre-defined algorithm corresponding with coded lock secret key of unblanking, and secret key of unblanking is that secret key terminal is used for opening coded lock, pre-defined algorithm and secret key generating algorithm.Because the pre-defined algorithm in coded lock is fixing, simultaneously with the predetermined period in coded lock for benchmark, the condition making secret key terminal can open coded lock is: the pre-defined algorithm of secret key terminal and consistent in coded lock, and predetermined period is synchronous with coded lock.
The step that synchronous communication set up by secret key terminal and coded lock is specially following two steps:
1. secret key terminal initiates synchronization request to coded lock, asks secret key terminal to upgrade unblank cycle of secret key and coded lock and upgrades the cycle synchronisation of opening secret key.
2. coded lock responds described synchronization request, and sets up synchronous communication with secret key terminal and be connected.
Above-mentionedly set up in the step of synchronous communication, namely secret key terminal sends synchronization request asks coded lock to send the predetermined period of coded lock to secret key terminal.Coded lock response synchronization request sends to secret key terminal by the predetermined period in coded lock, thus coded lock is consistent with the predetermined period of secret key terminal, namely sets up synchronous communication and connects.
In the present embodiment, coded lock responds described synchronization request, and sets up with secret key terminal the step that synchronous communication is connected and specifically comprise:
1. coded lock sends the time threshold of internal timer to secret key terminal.
2. secret key terminal is according to the time threshold of the time threshold setting secret key terminal inner timer of the internal timer of coded lock, thus completes synchronous communication connection.
The time threshold of coded lock internal timer and predetermined period, coded lock internal timer carries out timing according to predetermined period, when timing reaches identical with predetermined period value, namely reaches time threshold, and the pre-defined algorithm in coded lock then generates new unlatching secret key.
After the time threshold of internal timer is sent to secret key terminal by coded lock, the time threshold of internal timer changes to consistent with the internal timer of coded lock by secret key terminal, therefore, secret key terminal is consistent with the predetermined period of coded lock, namely generate secret key of unblanking consistent with the Time And Frequency opening secret key, thus complete synchronous communication connection.
In the present embodiment, coded lock is under the time threshold of internal timer drives, the unlatching secret key new according to predetermined generation, described secret key terminal synchronizes ground, under the time threshold of internal timer drives, generates new the unblank secret key corresponding with coded lock according to the described pre-defined algorithm corresponding with coded lock.Concrete steps are: when the time of the internal timer of coded lock reaches threshold value, activate pre-defined algorithm and generate new unlatching secret key.
The time threshold of the internal timer of secret key terminal is corresponding with the threshold value of coded lock, when reaching threshold value, the activation pre-defined algorithm corresponding with coded lock is generated new unlatching secret key.
In the present embodiment, coded lock has unique and identical pre-defined algorithm with secret key terminal, thus only need predetermined period to be set to consistent and synchronous, just can realize unlatching secret key that coded lock generates and the secret key moment of unblanking that secret key terminal generates is consistent.
In a further embodiment, secret key terminal can store multiple different pre-defined algorithm, and each pre-defined algorithm can correspond to the unique pre-defined algorithm had in a coded lock.And under normal circumstances, the cycle of each pre-defined algorithm renewal secret key is not identical.Because the update cycle of different pre-defined algorithms is different, so corresponding in secret key terminal, there is several timers, be connected with corresponding secret key generation unit respectively.A kind of pre-defined algorithm is only had in coded lock, therefore, coded lock only needs the secret key generate pattern identification code of pre-defined algorithm to send to secret key terminal, informing that secret key terminal opens secret key algorithm used is which kind of algorithm in secret key terminal, in coded lock, correspondence only has a timer, the timer synchronization corresponding with secret key terminal.Coded lock is by sending secret key generate pattern identification code, make the pre-defined algorithm in secret key terminal identical with the pre-defined algorithm in coded lock, simultaneously, update time again can be synchronous, so the effect that coded lock and secret key terminal generate identical secret key can be realized simultaneously, accomplish the automation of secret key timing renewal rewards theory, completely transparent to user, improve the safety of coded lock.
Secret key terminal with set up between coded lock and communicate after, secret key terminal sends initialization requests to coded lock, and the pre-defined algorithm consistent with coded lock is determined in request, thus all consistent with coded lock with pre-defined algorithm in predetermined period, thus controls coded lock.
Coded lock sends current unlatching secret key and secret key generate pattern identification code to secret key terminal after receiving initialization requests.
The current unlatching secret key be stored in coded lock and secret key generate pattern identification code are sent to secret key terminal after receiving initialization requests by coded lock.Current unlatching secret key is used to the secret key of unblanking of authentication password interlocking receipts, secret key generate pattern identification code is used to mark pre-defined algorithm, in coded lock, pre-defined algorithm in secret key generate pattern identification code uniquely tagged coded lock, but in secret key terminal, store many algorithms, therefore, only have when the secret key generate pattern identification code of the algorithm in secret key terminal is with consistent in coded lock, this secret key terminal can control to open this coded lock.
Secret key terminal stores after receiving described unlatching secret key and secret key generate pattern identification code and opens secret key, and select the pre-defined algorithm corresponding with coded lock according to secret key generate pattern identification code, and be specially opening the memory address of secret key and being recorded in the address search table of corresponding pre-defined algorithm: select the pre-defined algorithm corresponding with coded lock according to secret key generate pattern identification code, namely there is the algorithm of the secret key generate pattern identification code identical with coded lock, and the memory address of opening secret key is recorded in the address search table corresponding to pre-defined algorithm.
Open secret key and correspond to secret key access unit address, namely open the memory address of secret key.Open the content of secret key and correspond to the data that secret key memory cell stores.Store some pre-defined algorithms in secret key terminal, often kind of pre-defined algorithm, all with an address search table, have recorded in secret key memory cell the secret key memory address adopting this pre-defined algorithm to carry out secret key renewal in address search table.When pre-defined algorithm generates new secret key, new secret key is override corresponding secret key in secret key memory cell according to the memory address in the look-up table of address by secret key generation unit.
In the present embodiment, after secret key terminal receives and opens secret key and secret key generate pattern identification code, current unlatching secret key is stored, send to secret key generate pattern to activate unit in memory address this secret key simultaneously, it is in fact a multi channel selecting module that secret key generate pattern activates unit, it is according to the secret key generate pattern identification code from coded lock, select the path that corresponding with current unlatching secret key, this path is connected with the pre-defined algorithm corresponding to coded lock with secret key generation unit, then by this path, the memory address of current unlatching secret key is recorded in the address search table corresponding to pre-defined algorithm.
Step S120, secret key terminal sends to coded lock unblank checking request and secret key of unblanking, described in secret key of unblanking upgrade according to described predetermined period and pre-defined algorithm.
Secret key terminal is when unblanking, and need to send to coded lock unblank checking request and secret key of unblanking, secret key of wherein unblanking upgrades according to predetermined period and pre-defined algorithm.In secret key terminal, store the pre-defined algorithm corresponding with coded lock, pre-defined algorithm is also upgrade by predetermined period.When the pre-defined algorithm in secret key terminal also upgrades by predetermined period, secret key of unblanking will be generated.Be connected owing to establishing synchronous communication between coded lock with secret key terminal, therefore, when the cycle is identical with algorithm, synchronously can generate corresponding unblank secret key and unlatching secret key.
Step S130, checking request of unblanking described in coded lock response, reads described unlatching secret key, and described secret key of unblanking is compared with unlatching secret key, and whether secret key of unblanking described in judgement is consistent with unlatching secret key, if so, then drives unlocking mechanism to unblank.
After coded lock and secret key terminal establish a communications link, secret key terminal sends to coded lock checking request of unblanking, and sends the secret key of unblanking be stored in secret key terminal simultaneously.Coded lock makes response after receiving the checking request of unblanking from secret key terminal---and namely from coded lock memory cell, read current unlatching secret key, then contrast with the secret key from secret key terminal.If two secret keys are consistent, then send to access control module index signal of unblanking, drive unlocking mechanism to unblank; If two secret keys are inconsistent, then send miscue information to secret key terminal.
In the present embodiment, described secret key terminal has multiple pre-defined algorithm, and the pre-defined algorithm in described coded lock is corresponding with the one in the multiple pre-defined algorithm in secret key terminal.Only have a kind of pre-defined algorithm in coded lock, and have multiple pre-defined algorithm in secret key terminal, therefore, as long as there be the algorithm corresponding with coded lock just can control this coded lock in secret key terminal, thus a secret key terminal can control multiple coded lock.
In the present embodiment, to unblank secret key according to transmitting secret key request forwarding between secret key terminal and secret key terminal.Namely can also set up communication between secret key terminal, the secret key of unblanking stored be sent to other secret key terminal in secret key terminal.Owing to receiving the pre-defined algorithm in coded lock not corresponding with secret key of unblanking in the secret key terminal of secret key of unblanking, therefore, receive the secret key terminal of opening secret key and can not open secret key with coded lock synchronized update.
Based on above-mentioned all embodiments, the operating process of coded lock control method is as follows: initialize between coded lock and secret key terminal, namely the information and secret key generate pattern identification code of opening secret key will be passed to secret key terminal by coded lock, and secret key terminal realizes initialization procedure by preserving to open secret key and select to generate the pre-defined algorithm opening secret key according to secret key generate pattern identification code.After completing initialization between coded lock and secret key terminal, namely coded lock sets up complete synchronous communication with secret key terminal, and secret key terminal can control unlocking coded lock and locking.
Coded lock and secret key terminal are in initialized process, and the information and secret key generate pattern identification code of opening secret key are passed to secret key terminal by coded lock.Secret key terminal selects corresponding pre-defined algorithm according to secret key generate pattern identification code, and unlatching secret key is stored and memory address is recorded in the address search table corresponding to pre-defined algorithm.
After stating operation in realization, coded lock and secret key terminal under the driving of the time threshold of internal timer, can generate new unlatching secret key according to pre-defined algorithm.It is identical with a kind of pre-defined algorithm in secret key terminal that coded lock generates the pre-defined algorithm opening secret key, and therefore, when the time is identical, pre-defined algorithm generates identical unlatching secret key.
