Specific embodiment
In order to make the foregoing objectives, features and advantages of the present invention clearer and more comprehensible, with reference to the accompanying drawing and specific real
Applying mode, the present invention is described in further detail.
The embodiment of the present invention discloses a kind of sensing data and adaptively acquires real-time report method, and this method is applied to Internet of Things
In net gateway system, as the data transmission method of a kind of sensing network and conventional communication networks, play a part of data transmission,
Wherein sensing network refers to that various the sensor devices such as temperature sensor, pH value of the operative scenarios such as industrial and agricultural production sense
Device, air velocity transducer etc.；And conventional communication networks refer to some application servers in internet.As shown in Figure 1, being this
A kind of sensing data that inventive embodiments part provides adaptively acquires the system structure diagram of real-time report method.
In the present embodiment, it is complete by two threads that things-internet gateway realization adaptively acquires real-time report to sensing data
At being that sampling and reports thread at thread respectively, wherein sampling thread is mainly responsible for the data of circle collection sensor, report thread
Being mainly responsible for timing reports the average value of sensing data to server.
The described method comprises the following steps: step 1, sampling thread initialization judges the sensing accessed in Internet of things system
Whether the quantity of device is less than or equal to the preset quantity threshold value that can access the sensor of the Internet of things system, if so, executing
Step 2, it alerts and exits if it is not, then sampling thread；
Step 2, if the quantity of the sensor is less than or equal to preset quantity threshold value, judge that the quantity of the sensor is
No is 0；
Step 3, if the quantity of the sensor is not 0, according to the quantity of the sensor, when initialization sampling is slept
Between, the sampling sleeping time is per interval time between the value for acquiring sensor twice；
Specifically, in this step, if the quantity of sensorThen enable IfThen enable Tsleep=0.
Wherein, N is the quantity for accessing the sensor of Internet of things system, and Nmax is the sensor that can access Internet of things system
Preset quantity threshold value, Tperiod are default report cycle, and Cmin is the minimum in a default report cycle to each sensor
Times of collection, it is in a default report cycle to each sensor that the minimum times of collection Cmin, which is greater than or equal to 2, Cmax,
Maximum times of collection, Ttransaction be acquire primary transducer value needed for spend shortest time, Tsleep be adopt
Sample sleeping time.
Step 4, the sampling thread is acquired using sampling sleeping time as the value of time interval circle collection sensor
Value.
In this step, if the sampling sleeping time is equal to 0, the value of next sensor is and then acquired；If described adopt
Sample sleeping time is not equal to 0, after the time of the sensor sleep reaches sampling sleeping time, acquires next sensor
Value.Specifically, including multiple sensors in system, the value of a sensor is acquired every time, then acquires next sensor
Value after complete one time to be collected, then carries out second time acquisition.
In the present embodiment, in order to carry out debounce to sampled data, thread is sampled in a default report cycle to sensing
Device carries out multiple repairing weld, and such as Fig. 2 is that a kind of sensing data that part of the embodiment of the present invention provides adaptively acquires real-time report
The workflow schematic diagram that thread is sampled in method, is implemented as follows:
Judge whether the number of probes accessed in system is greater than the preset quantity of the sensor of accessible Internet of things system
Threshold value Nmax；
If the number of sensors accessed in system is greater than preset quantity threshold value Nmax, alarm, sampling thread exits extremely；
If the sensor accessed in system is less than or equal to preset quantity threshold value Nmax, the number of sensor in judgement system
Whether amount is 0；
If the quantity of sensor is 0 in system, fair termination samples thread；
If the quantity of sensor is not 0 in system, initialized according to the quantity N of sensor between sampling twice in succession
Sampling sleeping time Tsleep, it is specific as follows:
Things-internet gateway real-time report of the present invention meets following formula, respective figure 4:
Tperiod=C*N* (Ttransaction+Tsleep) (1.1)
Wherein, Tperiod indicates a default report cycle, as shown in figure 4, a sampling period T1, C expression one is pre-
If the times of collection in report cycle, N indicates the quantity of the sensor of access Internet of things system, when Tsleep indicates sampling sleep
Between.Wherein Ttransaction indicates the minimum time spent needed for the value of acquisition primary transducer, for 485 buses,
Including Tdata and Tmute, as described in following formula:
Ttransaction=Tdata+Tmute
Wherein, Tdata refers to that data the time it takes of acquisition primary transducer, specific logic of segmenting include:
write(…)；Select (..., T-timeout)；read(…)；Tdata is not unfolded in the practical derivation of equation.
Tmute refers to the silence period, and Modbus bus is sharing mode, needs to protect in bus between twi-read operation
One section of silence period Tmute is held to avoid interference, which carries out after and then bus operation.
In the present embodiment, the silence period Tmute is to be grasped according to an empirical fixed value by the suspend mode
Make, can guarantee the normal work of Modbus bus.
For formula (1.1), presetting report cycle Tperiod in actual operation is to be determined by demand, and acquire one
The shortest time Ttransaction spent needed for the value of secondary sensor is determined by hardware performance, wherein variable parameter is just
It is times of collection C in a default report cycle, the quantity N of sensor and sampling sleeping time Tsleep.
When the quantity N of sensor is smaller, guarantee the maximum times of collection in a default report cycle to each sensor
The processing of Cmax.
Why times of collection C in report cycle default for one does not take in acquisition primary transducer data
Report primary way, but take once report before carry out multi collect data way, main purpose be for deburring,
Carrying out multiple repairing weld to sensor before once reporting also is exactly one of demand.But the number of multiple repairing weld is also limited
, the maximum times of collection Cmax in a default report cycle to each sensor is denoted as in the present invention, in conditions permit
In the case of, wish to sample Cmax times in a default report cycle in the present invention.In the case where guaranteeing C=Cmax, sampling
The time of sleeping time Tsleep reduces, such as following formula as the quantity N of equipment increases:
When sampling sleeping time Tsleep is reduced to the limit i.e. 0, the quantity of the sensor of Internet of things system is accessed
N has one to meet in a default report cycle to the limiting value of the maximum times of collection Cmax of each sensor, is denoted as Nmid
=Tperiod/ (Cmax*Ttransaction), so being obtained when the quantity N of the sensor of access Internet of things system is smaller
Following relational expression:
When the quantity N of the sensor of access Internet of things system is larger, times of collection C is with the sensing for accessing Internet of things system
The variation of the quantity N of device and change.
If supporting the quantity N for more accessing the sensor of Internet of things system, fixed sample is slept on formula (1.1)
Sleep time Tsleep=0, when the quantity N of the sensor of access Internet of things system becomes larger, It is not necessary to acquiring every time
Insertion sampling sleeping time Tsleep, simple at this time between the minimum time Ttransaction spent needed for the value of primary transducer
Change formula (1.1) to obtain:
Tperiod=C*N*Ttransaction, available after deformation:
Formula (1.4) shows that the quantity N of the sensor with access Internet of things system continues to become larger, times of collection C gesture
Necessity reduces, and times of collection C can be a decimal during this, and it is default at one to illustrate that the algorithm in the present invention does not require
Sampling period in report cycle Tperiod is an integer, and physical meaning is one default report cycle of permission in the present invention
In the accessed number of each sensor be different.But otherwise times of collection C cannot mean default at one less than 1
There is sensor not to be accessed in report cycle, this does not allow.Currently in order to deburring, regulation is supported in the present invention
Minimum times of collection C is denoted as the maximum times of collection Cmin=2 in a default report cycle to each sensor, corresponding
Nmax is exactly the quantity for the maximum sensor that system can be supported in the present invention:
In known default report cycle Tperiod when actual development, the minimum spent needed for the value of primary transducer is acquired
Time Ttransaction, the interior maximum times of collection Cmax to each sensor of a default report cycle, and at one
In default default report cycle the times of collection of each sensor be at least up to the present invention after minimum times of collection Cmin obtain as
Fruit will support the quantity N for more accessing the sensor of Internet of things system also possible, sample sleeping time Tsleep at this time
Meet following formula:
To sum up, sampling sleeping time Tsleep is as follows:
Wherein, the minimum time spent needed for the value of a default report cycle Tperiod, acquisition primary transducer
The data the time it takes Tdata and silence period Tmute of acquisition primary transducer in Ttransaction, one it is default
To the acquisition time of each sensor in the maximum times of collection Cmax of each sensor, a default report cycle in report cycle
Number is at least up to minimum times of collection Cmin and can configure, and is usually arranged as the empirical value obtained by test.
Occupy CPU always due to when sampling sleeping time Tsleep is 0, will cause sampling thread, to periodic report and
Communication response causes certain delay, therefore when sampling sleeping time Tsleep is 0, and sampling thread can call sched_
Yield () actively abandons CPU, so that other threads have an opportunity to be dispatched in time.
After initialization sampling sleeping time Tsleep, the value of circle collection sensor carries out sequential sampling, and sampling obtains
Value, that is, collection value of each sensor be temporarily stored in data buffer zone, access next time is provided and is used, so that subsequent report
Thread is quicker to the use of sensing data, improves the real-time reported, and the collection value of sensor refers to reading sensing
The data that device obtains, for example read a temperature sensor and obtain 28.3 degree of temperature, then the current collection value of temperature sensor
It is 28.3.After sampling a sensor and terminating, judge to sample whether sleeping time Tsleep is 0, if sampling sleeping time
Tsleep is not 0, and the time of sampling thread sleep Tsleep is allowed to carry out the acquisition of next sensor again.If when sampling sleep
Between Tsleep be 0, sampling thread does not sleep and directly carries out the acquisition of next sensor.
As shown in figure 3, being that a kind of sensing data that part of the embodiment of the present invention provides adaptively acquires real-time report side
