1. logical sensor definition
To any physical sensors in the sensing label, all make up the virtual spreadsheet data file of compact mode, realize the self-described function of physical sensors through spreadsheet.
In order to define logical sensor, in each the physical sensors self-described electronic data list file in the sensing label, all be designed with " logical sensor mapping " field, be mainly used in this physical sensors institute counterlogic type of sensor of definition.This field length is 2 bytes (totally 16, code is the 0-15 position), is " 0 through " logical sensor mapping " code bit
2" still be " 1
2" the corresponding logical sensor of physical sensors is set " opens " or " pass " state.
Table 1 has been listed the data type of the pairing logical sensor kind of 16 bit value, logical sensor " sampling " data in " logical sensor mapping " field.Wherein the 10-15 position is for keeping the position, so that expand corresponding logical sensor function according to the actual requirements.For example, if " logical sensor mapping " the field assignment in the physical sensors characteristic spreadsheet is 7000
16The time, the position is mapped as 0111000000000000
2, the 1st, 2,3 is set to " 1
2", the expression opening, other position is set to " 0
2", the expression closed condition representes that then physical sensors opened following 3 logical sensor functions: maximum logical sensor (the 1st), minimum value logical sensor (the 2nd) and mean value logical sensor (the 3rd).
Table 1 logical sensor definition list
Because the memory space that the logical sensor of stored data sets needs is bigger, and size can not expect, unlatching (can set logic yet and can only open) is not set as the logical sensor of the 7th, 8 and 9 mappings of code in the table 1 simultaneously.Even two or three are provided with unlatching simultaneously; Because the data of its storage have more overlapping in terms of content; Can select the data set of a most detailed logical sensor of sensing data recorded content to store, other data set generates according to this data set, thereby reduces memory space.
2. sensor sample parameter configuration
Strictly speaking; Should carry out parameter configuration to the data sampling of each logical sensor; But generally speaking; The sampling parameter of Different Logic sensor settings is basic identical in the same physical sensors, and the realistic meaning that each logical sensor is configured is not too big, has increased the complexity of system yet.This method only adopts the physical sensors sampling parameter is configured, and all logical sensor sampling parameters that this physical sensors is corresponding are identical with it.As shown in table 2 to physical sensors sampling parameter fields configured.
Table 2 physical sensors sampling parameter configuration field
The implication and the setting of each field in the explanation sensor sample allocation list below, wherein:
Setup time and beginning sampling time.Data format adopts the UTC timestamp, begins from 1970-01-0100:00:00, and during configuration, real-time clock should be arranged to totally 32 of 4 bytes, is accurate to 1 second.
Sampling interval.Sampling interval is the time span of the double sampled data of transducer.Sampling interval is expressed as 16 codings.When the highest order coding is configured to 0
2The time, sampling time interval is by second calculating; When the highest order coding is configured to 1
2The time, sampling time interval calculates by dividing; 15 remaining binary system unsigned numbers that can be encoded into 15, express time second number or the number of minutes at interval, coding 0000000000000000
2Be used to represent continuous sampling.
Whether sensor states essential record physical sensors can use; Sensing data length is represented the byte number of sensor sample data; Whether warning is preset the expression transducer and is reported to the police and when report to the police; Report to the police and trigger to be provided with to represent whether upload data after the sensor record warning sampled data; Alarm condition representes whether be in alarm condition when front sensor.Sensor states, sensing data length, report to the police preset, report to the police trigger be provided with and alarm condition altogether byte length be 1 byte, in the byte each be provided with as shown in table 2.
Low alarm setting and high alarm setting are the high low level threshold values that the sensor-triggered of setting is reported to the police.For example be-10 ℃ to+75 ℃ temperature sensor for temperature-measuring range, the low level threshold setting is-1 ℃, and high-order threshold setting is+28 ℃, and the decimal system threshold value that sets need convert binary numeral on request to.
3. logical sensor realization mechanism
The function that logical sensor is mapped as logical sensor defines; Logical sensor sampling parameter configuration record the basic parameter of sampling of transducer, introduce storage organization pattern, the operating mechanism of logical sensor and the algorithm of logical sensor function of logical sensor data in sensing label below and realize.
3.1 sensor senses data storage organization pattern
The memory space of sensing label is mainly used in storage relative article static attribute information and sensor sample information.In practical application, because sensing data is gathered for a long time, need bigger memory space, and the sensing label limited storage space.Thereby the basic principle of system design is that storage is designed to cramped construction in the sensing label, reduces the memory space of sensing label, and the work of a large amount of memory spaces of needs and complicated calculations is placed in the read write line.
Because dynamic assigning memory can cause the bigger expense of system in sensing label; We adopt forms mode to the organizational form of sensor related data in the sensing label, write down the fields such as characteristic spreadsheet, sensor sample parameter configuration table, sensing data address of the unique identification spreadsheet of transducer, the transducer of each physical sensors successively.Wherein, The unique recognition coding in the unique identification spreadsheet of the transducer essential record physical sensors whole world; The sensor characteristics spreadsheet carries out transducer self-described, includes " logical sensor mapping " field and is used to define the corresponding logical sensor of physical sensors, and the sensor sample configuration mainly is the configuration parameter of record physical sensors sampling; The logical sensor data address is pointed to the memory space of logical sensor " sampling " data; Wherein the logical sensor sampled data of forms data value is provided with fixing address space respectively, and the logical sensor data set of continuous sampling only is provided with a shared continuous sampling memory space, and is as shown in Figure 2.For the storage of long-time continuous sampled data, can adopt storage policies such as " memory space completely then stops ", " circulation storage ".

Be example so that temperature, humidity and three physical sensors of vibration to be arranged in the sensing label (sensor node) below, transducer number is respectively SENSOR1, SENSOR2 and SENSOR 3, and the operation of analyzing logical sensor function in the sensing label realizes.
3.3.1 physical sensors operation control
MCU is to three physical sensors in the sensing label in the sensing label (sensor node)
The false code that realizes control is following:
Wherein, handle when physical sensors starts and call function IMPLEMENTSENSOR during to the sampling time (transducer number) handles physical sensors sampling and follow-up data.
3.3.2 the mapping of physical sensors and a plurality of logical sensors
To any one physical sensors in the sensing label (sensor node), the function of corresponding a plurality of logical sensors realizes it being through call function IMPLEMENTSENSOR (transducer number).The false code that its function is realized is following:
Wherein, PHYSENSORCOLLECT () is the physical sensors sampling function, the sampling sensor currency; After obtaining sampled value, compare with setting threshold; If surpass setting threshold, according to warning parameter determining be set and whether report to the police, and judge whether sampled value is uploaded.Then, judging whether to call the counterlogic transducer according to the numerical value of " logical sensor mapping " field meta carries out " sampling " and handles.The function that calls under the CASE condition all is single logical sensor function treatment function, realizes currency, maximum and minimum value logical sensor function respectively like function G ETPRESENTVALUE (), GETMAXVALUE (), GETMINVALUE () etc.3.3.3 single logical sensor function implementation algorithm
Realize for each logical sensor function, need write concrete logical sensor function and realize function.Because currency, maximum, minimum value, mean value, variance, surpass maximum record number of times, the data that surpass logical sensors " sampling " such as minimum value record number of times adopt forms data to store in sensing label, thereby in the function realization, have related algorithm.Promptly how obtain this " sampling " value of logical sensor through logical sensor " sampling " value last time and current physical sensors sampled value.Each logical sensor all has an implementation algorithm, describes its algorithm as an example with the mean value logical sensor below and realizes.
The logical sensor of averaging realizes that the algorithm of function G ETAVERAGEVALUE () is following:
I) the 1st collection value of physical sensors is N
0, average
Establish ii) that the n time (n>=1) mean value logical sensor calculate average is
Iii) the inferior physical sensors sampled value of n+1 (n>=1) is N
nThen the average in n+1 sampling of mean value logical sensor does
3.4 read write line is to the visit of logical sensor data
Read write line sends the instruction of reading the logical sensor data according to the instruction of daemon software with wireless mode to sensing label.After sensing label receives the instruction of read write line, call its intrinsic function the logical sensor data are conducted interviews.Intrinsic function at first finds sensing data storage list space in the sensing label memory space; In table space, find the physical sensors corresponding record; Find " sampling " numerical value of counterlogic transducer according to the logical sensor address data memory; As shown in Figure 2, and will be somebody's turn to do the primary control program that " sampling " numerical value and physical sensors characteristic spreadsheet and sensor sample parameter return to sensing label.The sensing label primary control program feeds back to read write line with above-mentioned three types of numerical value with wireless mode; Read write line is according to physical sensors characteristic spreadsheet and sensor sample parameter; In conjunction with the built-in data template of read write line; Come " sampling " numerical value of resolution logic transducer, and can give the actual physical meaning.Logical sensor " sampling " The data XML language after read write line will be resolved is packed, and the daemon software that is transferred to the upper strata is handled.
4. embodiment
