Specific embodiment
Fig. 1 is the flow chart of the time calibrating method embodiment one of control of bluetooth access equipment of the present invention, the bluetooth of the embodiment
The time calibrating method of access control equipment the following steps are included:
Step S10: receiving door open command transmitted by multiple Bluetooth terminals, and obtains the local reception of each door open command
Time, wherein the door open command includes terminal current time.
In this step, it should be noted that, the resident in cell can pass through institute when prohibiting door using the enabling of its Bluetooth terminal
The bluetooth connection channel of foundation sends door open command to control of bluetooth access equipment, alternatively, broadcast door open command.The door open command includes
First encryption information and the second encryption information.Wherein, the first encryption information is that background server believes user identifier using private key
The information such as breath, room number information, user password, validity period carry out encrypting information generated, and user infuses before first use
When volume, Bluetooth terminal receives the first encryption information transmitted by background server, and is carried out using public key to the first encryption information
Decryption, to obtain user password.And the second encryption information be Bluetooth terminal using user password to the MAC of control of bluetooth access equipment
Location, terminal current time, door opening command carry out encrypting information generated.Control of bluetooth access equipment is sent out receiving Bluetooth terminal
After the door open command sent, the first encryption information is decrypted using public key first, user password is got, then reuses use
The second encryption information is decrypted in family password, can get terminal current time.In a concrete instance, preset time
Section is, for example, 8 hours, if 100 door open commands are received in 8 hours altogether, and the local for recording each door open command respectively connects
Between time receiving, moreover, terminal current time can be got by carrying out parsing by clamshell doors instruction.
Step S20: according to local reception time corresponding to each door open command and terminal current time, when calculating calibration
Between be worth.
In this step, if control of bluetooth access equipment leads to local clock not due to being exhausted by adverse circumstances or battery influences
Standard, then (bluetooth is whole for the local reception time (clock signal of control of bluetooth access equipment itself) of door open command and terminal current time
The clock signal at end) it will will appear biggish error (minute rank), the time of the transmission of instruction is relatively negligible, therefore can
Prover time value is calculated according to the terminal current time in multiple door open commands.
Step S30: according to the prover time value calibration local clock.
After calibrating local clock, control of bluetooth access equipment can accurately record the transit time of user, particularly with logical
Cross enabling of swiping the card user or by passwords of visitors open the door user (control of bluetooth access equipment also supports swipe the card enabling and passwords of visitors
It opens the door).
Implement the technical solution of the embodiment, control of bluetooth access equipment extracts terminal therein when receiving door open command
Current time, and the local reception time of recording instruction.Moreover, when according to local reception corresponding to multiple door open commands difference
Between and terminal current time can calculate prover time value, and then use the prover time value calibration local clock.On the one hand,
It, can be to local clock when control of bluetooth access equipment leads to local clock inaccuracy due to being exhausted by adverse circumstances or battery is influenced
Calibrated, thus can accurate recording user transit time, provide guarantee for the room entry/exit management of cell personnel；It is another
Aspect is the terminal current time in door open command as based on, so not needing additionally to mention when calibrating local clock
For standard clock signal (such as GPS signal), therefore additional cost will not be generated.
Fig. 2 is the flow chart of step S20 embodiment one in Fig. 1, and the step S20 of the embodiment includes:
Step S21: terminal current time corresponding to each door open command is subtracted each other with the local reception time respectively, to obtain
Take corresponding time difference；
Step S22: it averages to acquired time difference；
Step S23: local current time is added with the average value, to obtain prover time value.
In a specific embodiment, if certain control of bluetooth access equipment respectively 8:21,8:28,8:31,8:33,8:34,
8:39,8:40,8:41,8:43,8:45 (local reception time) receive door open command, altogether ten door open commands, and this ten
Terminal current time in a door open command be followed successively by 8:24,8:30,8:35,8:37,8:37,8:41,8:39,8:45,8:46,
8:48.Then in the step s 21, respectively by terminal current time corresponding to this ten door open commands and local reception time phase
Subtract, acquired time difference (minute) is successively are as follows: 3,2,4,4,3,2, -1,4,3,3.In step S22, to this ten times
Difference is averaged, and it is about 3 minutes (being accurate to minute) that average value, which can be obtained,.In step S23, if the sheet of control of bluetooth access equipment
Ground current time is 8:50, then can calculate prover time value is 8:53.After using the prover time value calibration local clock,
The clock signal of control of bluetooth access equipment just restores accurate.
Further, control of bluetooth access equipment is influenced and causes local clock pulses inaccurate being exhausted by adverse circumstances or battery
When true, generally it can all be lagged than the standard time, without advanced very much, for example, 5 minutes evenings were normal, but not in advance 20
Minute.Based on this, getting multiple door open commands respectively after corresponding time difference, step S21 and step S22 it
Between, can also further comprise:
Step S24: judging whether time difference corresponding to the door open command is less than preset value, should if so, rejecting
Time difference corresponding to door open command, wherein the preset value is less than 0, and for example, -15 minutes.
For example, in one example, if time difference corresponding to multiple door open commands (minute) be respectively as follows: 3 ... ,-
25 ..., 2, then " -25 " in this group of time difference can be weeded out, only be averaged to remaining time difference.
Still further, by personal habits or it is various other due to, the clock signal and mark of the Bluetooth terminal of user
May also there be error between punctual.Based on this, when being calculated according to terminal current time, when in order to obtain more accurate calibration
Between be worth, between step S21 and step S22, may also include that
Step S25: the disposal of gentle filter is carried out to acquired time difference.
For example, in one example, if time difference corresponding to multiple door open commands (minute) is respectively as follows: 3,19,4,
4,3,2, -13,4,3,3, then can by this group of time difference maximum value " 19 " and minimum value " -13 " weed out, only to remaining
Time difference average.
