Specific embodiment
The present invention is described in more detail with reference to the accompanying drawings and examples.
The invention discloses a kind of control device that rate is arrested for improving active card, as shown in figure 1, it includes master control
Device processed 1, the master controller 1 is electrically connected with wireless module 2, and the master controller 1 is built-in with timer 3 and random number module
4, wherein：
The random number module 4 is used to generate random number；
The timer 3 is used to after it reaches timing, an interrupt signal is sent to master controller 1；
The master controller 1 is used for：Response interrupt signal simultaneously sends data by wireless module 2, when data is activation is completed
The random number in random number module 4 is read afterwards, and random number is write into timer 3, to make timer 3 by random number as timing
Time reclocking.
Operationally, after active card initialization, timer 3 starts timing to above-mentioned control device, when timer 3 reaches fixed
When the time after, send an interrupt signal to master controller 1, the response interrupt signal of master controller 1 and is sent by wireless module 2
Data, the random number in reading random number module 4 after the completion of data is activation, and random number is write into timer 3, timing afterwards
Random number as timing reclocking is repeated said process by device 3.The present invention generates random number using random number module 4,
Random number is write into timer 3 again so that each timing of timer 3 is different, so as to reduce multiple active cards simultaneously
Send the possibility of data, it is to avoid loss of data, substantially increase active card arrests rate so that active card identification process
Accuracy and better reliability.
In practical application, the generation on random number refers to following examples：Master controller 1 is built-in with initial time
T0, the T0 can be changed by master controller 1, and it is 0, T1 that the random number module 4 is used to produce the initial value of random numerical value T1, T1
In 0~10 random change, after sending data every time, T0+T1 is write timer 3 by random number module 4 to scope, by
Change at random in T1, it is achieved thereby that the change at random of the timing of timer 3.
In the present embodiment, the wireless module 2 is preferably 2.4G wireless modules.
On this basis, the active card is preferably RFID active cards.So that active card can not only rely on 13.56MH modules
Radio-frequency carrier is realized, telecommunication can also be realized using 2.4G wireless modules.
Used as a kind of preferred embodiment, the random number module 4 is realized by the built-in program code of master controller 1.This is random
Digital-to-analogue block 4 can write master controller 1 in programming, so that master controller 1 is called.The random number of the random number module 4 generation
It is integer.
In the present embodiment, the master controller 1 is single-chip microcomputer.The timer 3 is built in the single-chip microcomputer.
Used as a kind of preferred embodiment, the timer 3 presets the initial timing time, when electricity is initial in active card, institute
State timer 3 carries out timing according to the initial timing time.This set is in order to avoid lacking initial time in timer 3
Interruption cannot be produced, to ensure that active card can smoothly enter working condition, but this is only a kind of application mode of the invention,
In addition, the present invention is it is also conceivable to another working method：Initial in upper electricity, master controller 1 first sends data, pending data
After being sent completely, random number module 4 is recalled, make the timing of timer 3.Both modes can be when programming to master controller 1
It is configured, the two can play foolproof function.
In the present embodiment, the active card includes the memory module for data storage.
A random number module is added in control device disclosed by the invention, compared to existing technologies, the present invention exists
A small random delay is added on the basis of original interval, so that the transmission time of each active card that staggers to greatest extent,
So, even if preceding once several cards send out data simultaneously, and when sending next time, due to the addition of random number, each active card is simultaneously
The situation for sending out data will be substantially reduced.
On this basis, the invention also discloses a kind of control method that rate is arrested for improving active card, with reference to Fig. 1 and
Shown in Fig. 2, the method is realized based on a device, and described device includes master controller 1, and the master controller 1 is electrically connected with
Wireless module 2, the master controller 1 is built-in with timer 3 and random number module 4, and methods described comprises the following steps：
Step S1, initializes active card；
Step S2, timer 3 starts timing；
Step S3, timer 3 reaches timing, and an interrupt signal is sent to master controller 1；
Step S4, the response interrupt signal of master controller 1 simultaneously sends data by wireless module 2；
Step S5, master controller 1 will read the random number in random number module 4 after the completion of data is activation, and by random number
Write-in timer 3；
Random number as timing reclocking is back to step S3 by step S6, timer 3 afterwards.
In the above-mentioned control method that rate is arrested for improving active card, after sending data every time, given birth to using random number module 4
Into random number, then random number is write into timer 3 so that each timing of timer 3 is different, has so as to reduce multiple
Source card sends the possibility of data simultaneously, it is to avoid loss of data, and substantially increase active card arrest rate so that active card is known
The accuracy and better reliability of other process.
Further, the timer 3 presets the initial timing time, in the step S1, when electricity is first in active card
Begin, the timer 3 carries out timing according to the initial timing time.
In the control device and control method that rate is arrested for improving active card disclosed by the invention, on radio frequency smart card
After electricity, by the data in configuration memory, a secondary data is sent at regular intervals between active card meeting, be sent completely every time
Afterwards, the random number in random number module is read, is added in transmission interval counter, data are sent next time will be spaced newly
Timing, so as to once mutually staggering with preceding.Compared to existing technologies, sent out simultaneously present invention reduces multiple active cards
Send the possibility of data, it is to avoid loss of data, substantially increase active card arrests rate so that the standard of active card identification process
True property and better reliability.
