Specific implementation mode
In order to make the purpose , technical scheme and advantage of the present invention be clearer, with reference to the accompanying drawings and embodiments, right
The present invention is further elaborated.It should be appreciated that described herein, specific examples are only used to explain the present invention, not
For limiting the present invention.
Referring to Fig. 1, Fig. 1 is a kind of communication system 300 for Random Communication time interval that one embodiment of the invention provides
The communication system 300 of communication sequential chart, the Random Communication time interval includes multiple first equipment 100 and second equipment
200, it is applied in the acquisition of animal sign information, for example, the first equipment 100 is ear tag, the second equipment 200 is concentrator,
Ear tag is fixed on animal ear.Ear tag acquires animal life sign information (such as body temperature, posture, meter step etc.), passes through nothing
Line is sent to concentrator, then suspend mode.Concentrator is transmitted to remote server after receiving the data that ear tag is sent.Concentrator wakes up
Ear tag, ear tag enables alarm module (indicator light, Flash board, buzzer etc.), convenient artificially to find the ear tag.
When first equipment 100 sends communication data, there is the possibility for conflicting with each other and interfering.Therefore, how to ensure multiple
The data acquisition of animal is not interfere with each other, and is urgent problem.
By taking ear tag and concentrator as an example, ear tag in a dormant state, until dormancy time ends, wakes up and acquires for a long time
Data, transmission data " at most primary ".It reloads after being sent random dormancy time, into suspend mode.Each transmission data
Byte number 35Byte, traffic rate 250kbps, 35/25000 ≈ 1.4ms ≈ 2ms.Tt=2ms, interference time 2Tt=
4ms, T=15 minutes, share timeslice 450000.It is P (1-1) that then module, which sends the probability once interfered by another module,
=2/450000=1/225000.It is by the probability that other 500 are interfered：P (1-500)=500*1/225000=1/450.
Tt is to emit single communication data duration, also referred to as single communication window.
In practical application, the local clock of ear tag may be synchronous with some other or certain several ear tag, causes to collide
Probability is excessively high, influences to use.It is local it is necessary to reduce ear tag local zone time and other ear tags to reduce the probability of such case generation
The probability of time synchronization, or be both to be synchronized also be disturbed after a certain time, otherwise the ear tag of synchronization time sends number
It is mutually collided according to being bound to, until the drift of respective crystal oscillator causes the asynchronous collision of clock that can just disappear.
Therefore, the present invention provides a kind of communication means of Random Communication time interval, which includes step S1：
S1, multiple first equipment 100 emit repeatedly communication number according to multiple random time intervals to the second equipment 200
According to the time interval is：
T=(B+S) * U
Wherein, T is the time interval, and S is the random number generated by preset function, and U is preset time basis
Unit, B are the basic number as obtained by basal latency calculating：
B=Tb/U
Tb is the basic time；The basal latency according within the preset unit interval first equipment 100 be averaged
The average time for emitting the communication data is configured.By taking ear tag and concentrator as an example, in practical application, it is ensured that have per hour
One valid data reports successfully, take herein per hour ear tag terminal at least emit 3 times to 6 data of multi-emitting.
Specifically, basal latency=unit interval/average time.
For the acquisition pattern of average time, which further includes step S2：
The number that S2, statistics first equipment emit within the unit interval, and calculated according to the number counted
The average time.If the unit interval is 1 hour, in 3 hours, distribution is penetrated 3 times, 4 times, 5 times, then average time=(3+
4+5)/3=4, basal latency 60min/4=15min, i.e. basal latency are 15 minutes.
Specifically：It is basic unit to take 20ms, is denoted as U.
The random number that note generates is denoted as S.
In order to meet average 4 transmitting data per hour, needs to take a basal latency Tb, take herein Tb=15 minutes.
In order to facilitate being superimposed into random algorithm, it is converted into basic number herein, is denoted as B.
B=Tb/U=15*60S/20ms=45000.
Preferably, which further includes step S3-S4：
The range of the random number is arranged in S3.Specifically, be superimposed on the basal latency preset positive random time and
Negative random time is to meet the emission maximum number of first equipment 100 and minimum emitting times in the unit interval：
- Tc ＜ S*U ＜ Tc
Tc is the positive random time, and-Tc is the negative random time.
Such as：It is superimposed positive and negative random time on basal latency, meets one hour and at least emit 6 times for 3 times to multi-emitting,
It is ± 5 minutes to take the random time for the basal latency that is added to, so -5min ＜ S*U ＜ 5min, -15000 ＜ S ＜ 15000.
S4, according to RTC clock counter value be used as random seed, according to the random seed generate it is described at random
Number.Step S4 includes step S41-S42：
S41, according to RTC (Real_Time Clock) clock counter value and floating AD (analog-to-digital conversion) circuit
Value is used as random seed；
S42, the random number is generated by the stdlib.h of the C java standard libraries srand functions provided and rand functions.
In MCU communication systems, real random number cannot be generated, additional uncertain variables is needed to increase randomness,
Value using the value of the counter of RTC clock and a floating AD is used as random seed, is provided using C java standard libraries stblib.h
Srand and rand functions generate random number.Specific practice is.
srand(time(rtc))；// using current time as the seed of random number generator
Int S=rand () %15000；
Int symbol=rand () %2
If (symbol==1)
S=S*-1；
}
Preferably, it is also necessary to upset a local clock every 24 hours, specific practice is, if RTC actual count values
After 24 hours full, floating ADC values are taken to generate the random number of a 0-450000, and the initial value of RTC is reseted this random number institute
The corresponding time.
Such as：In specific communication, it can also be involved in the problems, such as waking up ear tag, in conjunction with the present invention, ear tag fixed cycle (T=
20S) windowing (Tt=20ms), which receives, wakes up code.Ear tag judges that wake-up code is correct, is waken up and receives data.Receive correct number
According to rear, corresponding actions, such as flashing indicator light (but not limited to) etc. are done.Time of the ear tag except windowing enters dormant state.
Referring to Fig. 2, Fig. 2 is a kind of structural representation of the communication system 300 for random interval that one embodiment of the invention provides
Figure, multiple first equipment 100 wirelessly communicate be connected to second equipment 200 respectively.
