Detailed description of the invention
Fig. 1 is the composition block diagram of control device of the present invention.
Fig. 2 is the flow chart of control method of the present invention.
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 devices that rate is arrested for improving active card, as shown in Figure 1, it includes master control
Device 1 processed, the master controller 1 are electrically connected with wireless module 2, and the master controller 1 is built-in with timer 3 and random number module
4, in which:
The random number module 4 is for generating random number；
The timer 3 is used to send an interrupt signal to master controller 1 after it reaches timing；
The master controller 1 is used for: response interrupt signal simultaneously issues data by wireless module 2, when data are sent completely
The random number in random number module 4 is read afterwards, and timer 3 is written into random number, to enable timer 3 by random number as periodically
Time reclocking.
At work, after active card initialization, timer 3 starts timing to above-mentioned control device, determines when timer 3 reaches
When the time after, send an interrupt signal to master controller 1, master controller 1 responds interrupt signal, and issues by wireless module 2
Data read the random number in random number module 4 after data are sent completely, and timer 3 are written in random number, timing later
Device 3 is repeated the above process using random number as timing reclocking.The present invention generates random number using random number module 4,
Timer 3 is written into random number again, so that the timing difference that timer 3 is each, to reduce multiple active cards simultaneously
A possibility that sending data, avoids loss of data, and substantially increase active card arrests rate, so that active card identification process
Accuracy and reliability is more preferable.
In practical application, about the generation of random number, can refer to following examples: master controller 1 is built-in with initial time
T0, the T0 can be modified by master controller 1, and the initial value that the random number module 4 is used to generate random numerical value T1, T1 is 0, T1
Range is in 0~10 random change, and after sending data every time, timer 3 is written by random number module 4 by T0+T1, by
Change at random in T1, to realize the random variation of 3 timing of timer.
In the present embodiment, the wireless module 2 is preferably 2.4G wireless module.
On this basis, the active card is preferably RFID active card.So that active card can not only rely on 13.56MH module

Step S2, timer 3 start timing；
Step S3, timer 3 reach timing, send an interrupt signal to master controller 1；
Step S4, master controller 1 respond interrupt signal and issue data by wireless module 2；
Step S5, master controller 1 read the random number in random number module 4 after being sent completely data, and by random number
Timer 3 is written；
Step S6, timer 3 are back to step S3 using random number as timing reclocking later.
It is above-mentioned to be arrested in the control method of rate for improving active card, it is raw using random number module 4 after sending data every time
Timer 3 is written at random number, then by random number, so that each timing of timer 3 is different, so that reducing multiple has
A possibility that source card sends data simultaneously, avoids loss of data, and substantially increase active card arrests rate, so that active card is known
The accuracy and reliability of other process is more preferable.
Further, the timer 3 is preset the initial timing time, in the step S1, when active card powers on just
Begin, the timer 3 carries out timing according to the initial timing time.
It is disclosed by the invention to be arrested in the control device and control method of rate for improving active card, on radio frequency smart card
After electricity, by the data in configuration memory, a data are sent at regular intervals between active card meeting, are sent completely every time
Afterwards, the random number in random number module is read, is added to and sends in interval counter, sending data next time will be spaced newly
Timing, to once be mutually staggered with preceding.Compared to existing technologies, present invention reduces multiple active cards to send out simultaneously
A possibility that sending data avoids loss of data, and substantially increase active card arrests rate, so that the standard of active card identification process
True property and better reliability.
