Detailed description of the invention
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 this embodiment
The time calibrating method of access control equipment comprises the following steps:
Step S10: receive the door open command that multiple Bluetooth terminal is sent, and obtain the local reception of each door open command
Time, wherein, described door open command includes terminal current time.
In this step, it should be noted that, the resident family in community, when using the enabling of its Bluetooth terminal to prohibit door, can pass through institute
The bluetooth interface channel set up sends door open command to control of bluetooth access equipment, or, broadcast door open command.This door open command includes
First adds confidential information and second adds confidential information.Wherein, first add confidential information be background server use private key to ID believe
The information such as breath, room number information, user cipher, effect duration is encrypted generated information, and user notes before first use
During volume, what Bluetooth terminal received that background server sent first adds confidential information, and uses PKI to add confidential information to first to carry out
Deciphering, to obtain user cipher.And second to add confidential information be that Bluetooth terminal uses user cipher to the MAC of control of bluetooth access equipment ground
Location, terminal current time, door opening command are encrypted generated information.Control of bluetooth access equipment is sent out receiving Bluetooth terminal
After the door open command sent, add confidential information first by PKI to first and be decrypted, get user cipher, then re-use use
Family password adds confidential information to second and is decrypted, and just can get terminal current time.In a concrete instance, Preset Time
Section for example, 8 hours, if receiving 100 door open command in 8 hours altogether, and this locality recording each door open command respectively connects
Between the time receiving, and, carry out parsing by clamshell doors instruction and just can get terminal current time.
Step S20: according to the 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 is because being affected by adverse circumstances or running down of battery and cause local clock not
Standard, then (bluetooth is eventually for the local reception time (clock signal of control of bluetooth access equipment self) of door open command and terminal current time
The clock signal of end) it would appear that bigger error (minute rank), the time of the transmission of instruction is the most negligible, therefore may be used
Prover time value is calculated according to the terminal current time in multiple door open command.
Step S30: according to described prover time value calibration local clock.
After calibration local clock, control of bluetooth access equipment just can record the transit time of user exactly, particularly with logical
(control of bluetooth access equipment also supports swipe the card enabling and passwords of visitors for the user crossing enabling of swiping the card or the user opened the door by passwords of visitors
Open the door).
Implementing the technical scheme of this embodiment, control of bluetooth access equipment, when receiving door open command, extracts terminal therein
Current time, and the local reception time of recording instruction.And, according to multiple door open command respectively corresponding to local reception time
Between and terminal current time just can calculate prover time value, and then use this prover time value calibration local clock.On the one hand,
When control of bluetooth access equipment is because being affected by adverse circumstances or running down of battery and cause local clock inaccurate, can be to local clock
Calibrate, thus can the transit time of accurate recording user, the room entry/exit management for community personnel provides guarantee;Another
Aspect, when calibrating local clock, due to the terminal current time in be based on door open command, so need not additionally carry
For standard clock signal (such as gps signal), thus without producing additional cost.
Fig. 2 is the flow chart of step S20 embodiment one in Fig. 1, and step S20 of this embodiment includes:
Step S21: respectively the terminal current time corresponding to each door open command was subtracted each other with the local reception time, to obtain
Take corresponding time difference;
Step S22: acquired time difference is averaged;
Step S23: this locality current time be added with described meansigma methods, 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, ten door open command altogether, and this ten
Terminal current time in individual 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.The most in the step s 21, respectively by the terminal current time corresponding to these ten door open command and local reception time phase
Subtracting, acquired time difference (minute) is followed successively by: 3,2,4,4,3,2 ,-1,4,3,3.In step S22, to these ten times
Difference is averaged, and available meansigma methods is about 3 minutes (be accurate to minute).In step S23, if the basis of control of bluetooth access equipment
Ground current time is 8:50, then can calculate prover time value is 8:53.After using this prover time value calibration local clock,
The clock signal of control of bluetooth access equipment just recovers accurate.
Further, control of bluetooth access equipment affected by adverse circumstances or running down of battery and cause local clock pulses forbidden
Time really, the most all can be more delayed than standard time, without advanced a lot, such as, 5 minutes evenings were normal, but will not shift to an earlier date 20
Minute.Based on this, get multiple door open command respectively corresponding to time difference after, step S21 and step S22 it
Between, also can farther include:
Step S24: judge that the time difference corresponding to described door open command whether less than preset value, is the most then rejected and is somebody's turn to do
Time difference corresponding to door open command, wherein, described preset value be less than 0, for example,-15 minutes.
Such as, in one example, if the time difference (minute) corresponding to multiple door open command be respectively as follows: 3 ... ,-
25 ..., 2, then "-25 " in this group time difference can be weeded out, only remaining time difference are averaged.
Yet further, due to by personal habits or other a variety of causes, the clock signal of the Bluetooth terminal of user and mark
Error may be also had between Zhun Shi.Based on this, when calculating according to terminal current time, when calibrating more accurately to obtain
Between be worth, between step S21 and step S22, may also include that
Step S25: acquired time difference is carried out the disposal of gentle filter.
Such as, in one example, if the time difference (minute) corresponding to multiple door open command is respectively as follows: 3,19,4,
4,3,2 ,-13,4,3,3, then the maximum " 19 " in this group time difference and minima "-13 " can be weeded out, only to remaining
Time difference average.
