Embodiment
The present invention is by with the communication cycle randomization, provides with the form of probability density function, and by the relevant parameter of definition communication cycle, thereby the control communication cycle is to improve response promptness between the communication module and the contradiction between the energy consumption.
Below in conjunction with accompanying drawing and preferred embodiment technical scheme of the present invention is described in further detail:
As shown in Figure 1, a kind of electronic installation of the present invention, this device comprises at least two communication modules, one is access modules 14, one is accessed module (not shown), also comprise 11, one random access period generation modules 12 of a parameter memory module and a random access period computing module 13 (timer), wherein:
Parameter memory module 11: link to each other with random access period computing module 13, be used to store the communications access cycle relevant parameter that calculates according to energy consumption and response requirement;
Random access period generation module 12: directly link to each other with random access period computing module 13, be used to produce the standard random integers;
Random access period computing module 13: link to each other 14 with access modules, be used for calculating the communications access cycle according to communications access cycle relevant parameter and random integers;
Access modules 14: send communications access according to the communications access cycle that calculates to accessed module and instruct.
Described electronic installation is a mobile phone.
As shown in Figure 2, a kind of communications access periodic Control method based on electronic installation of the present invention may further comprise the steps:
Step S101: the relevant parameter that requires to calculate the communications access cycle according to energy consumption and response;
Step S102: it is standby that the relevant parameter that calculates is kept at the mobile phone terminal zone;
Step S103:, calculate the communications access cycle according to random integers that produce and the communications access cycle relevant parameter that calculates;
Step S104: the access modules in the described electronic installation is sent the communications access instruction according to the described communication cycle value that calculates to accessed module.
The described communications access cycle can obtain by dual mode: a kind of is directly directly to calculate the communications access cycle by deviant and scale factor; Perhaps deviant with scale factor is converted to average and variance calculates the communications access cycle again.
Below in conjunction with instantiation technical scheme of the present invention is described further.
For example: the communications access cycle between certain communication module is 1 minute, for cutting down the consumption of energy, will be extended for 2 minutes average period, and the maximum cycle is no more than 4 minutes; The probability density in communications access cycle is a normal probability paper density, and as shown in Figure 3, the random access period generation module generates 0～9 integer, and the probability that numeral occurs is normal distribution.
Step S201: require to calculate the relevant parameter of communication cycle according to energy consumption and response, present embodiment comprises scale factor and deviant;
According to designing requirement, by prolonging the reduction that realizes energy consumption average period.In this example, reduce half requirement according to energy consumption, average time of response was extended to 2 minutes from 1 minute, by controlling the promptness of maximum cycle control response, prevent that the long response time is untimely to the response of communication, the longest response time is the degrees of tolerance of user's reality.
The longest time is 4 minutes in this example, and it is negative that the long response time of while may be calculated the actual response time of back, and in actual applications, the response time scope in cycle is:
[average time-min (maximum duration-average time, average time), average time+Min (maximum duration-average time, average time)],
In this example, the response time is [0,4], if and the maximum duration requirement is 3, then the scope of response time is [1,3], if maximum duration is 5, response time is [0,4], because average time is constant, though because the difference of institute's coverage, cause there are differences on the individual responses (longest response time), but identical on energy consumption.
The method that random integers 0～9 and control time scope 0～4 are changed has a variety of, with the simplest linear mapping promptly:
The access cycle=scale factor * random integers+deviant;
Maximum the longest access cycle (9 correspondence 4) of random integers correspondence, minimum the shortest access cycle (0 correspondence 0) of random integers correspondence
Can draw scale factor is 4/9 (0.444), and deviant is 0;
Deviant is meant the minimum response time, but when scale factor is negative value, the corresponding maximum response time of deviant; Deviant is the poor of actual value and standard value.
Step S202: with scale factor and the deviant that calculates, the storage area that writes in the mobile phone terminal is standby;
Step S203: the random access period generation module produces random integers in the mobile phone terminal, scope is [0,9], distribution density function is normal distribution, and the random access period computing module calculates the current communications access cycle according to scale factor, the deviant of these random integers and preservation then:
The access cycle=scale factor * random number+deviant
Wherein, scale factor and deviant are the numerical value 0.444 and 0 that is stored in the parameter conservation zone,
Can calculate communication cycle:
Table 1 is the random integers that calculate by the random access period computing module and the relation list of communication cycle:
| Random integers | Access cycle |
| 0 | 0 |
| 1 | 0.44 |
| 2 | 0.89 |
| 3 | 1.33 |
| 4 | 1.78 |
| 5 | 2.22 |
| 6 | 2.66 |
| 7 | 3.11 |
| 8 | 3.56 |
| 9 | 4.00 |
After calculating access cycle, as random integers 9, corresponding 4 minutes access cycle, this value is scaled timer time, as 240 (produce the timer that interrupts for 1 time each second, occurrence is according to concrete timer decision), the timing that starts timer and timer is set is 4 minutes.
Step S204: access modules the current communications access cycle then after, visit accessed module, and return step S203.
In this example, be under 9 the situation when the random integers that produce, the communications access cycle that calculates is 4 minutes, after timer preset time (240s) arrives, produce an interruption, trigger that access modules is communicated, simultaneously repeating step S203, produce new random integers, calculate new communications access cycle and timer numerical value.
It is average and variance that another embodiment can be selected parameter for use, and the standard average of standard random function is 4.5, and standard variance is got σ=1.5; When given parameter was average and variance, advanced line parameter reasonability was judged: average-3* variance＞=0, Rational Parameters; Deny, then variance=average/3.
Itself and aforesaid method conversion relation are: scale factor=variance/1.5 (standard variance)
In the linear conversion relation: average=scale factor * 4.5+ deviant.
Other steps are consistent with scheme in the foregoing description, because scale factor and deviant and average and variance can be changed mutually, so directly by calculating scale factor and deviant or can drawing the value in communications access cycle by the method that computation of mean values and variance convert scale factor and deviant again to.
Certainly; the present invention also can have other various embodiments; under the situation that does not deviate from spirit of the present invention and essence thereof; those of ordinary skill in the art work as can make various corresponding changes and distortion according to the present invention, but these corresponding changes and distortion all should belong to the protection range of the appended claim of the present invention.
