If '15' is recorded in the year field 1913, the year in which the sensing information is measured is 2015.

If the value of the year base flag is '0', the year in which the sensing information is measured will be 1915.

1913 to 1918 represent the year-month-day-hour-minute-second in which the sensing information is measured, respectively, and can be expressed in the form of 'yyyy-MM-dd hh: mm: ss'.

The identifier number field 1930 is a field indicating the number of identifiers corresponding to the sensing value included in the sensing value field 1970.

That is, a value corresponding to '/ soil / 1' is recorded in the identifier information field 1950 and '/ soil / 1 / ec', '/ soil / 1 / temp' / soil / 1 / hum 'is included, a value corresponding to' 3 'is recorded in the identifier number field 1930.

By doing so, the sensing data can be transmitted without recording all the identifiers '/ soil / 1 / ec', '/ soil / 1 / temp', and '/ soil / 1 / hum' in the identifier information field 1950, / Soil / 1 / ec ',' / soil / 1 / temp ',' / soil / 1 / ecp ', and the values contained in the sensing value field 1970 through the number' 3 'recorded in the identifier number field 1930 quot; / hum ", it is possible to reduce the total length of the sensing data, thereby enabling efficient transmission of sensed data.

That is, the sensing data includes a plurality of sensing information (for example, '/ soil / 1 / ec', '/ soil / 1 / temp', '/ soil / 1 / hum' (E.g., '/ soil / 1') in which the respective identifiers for the plurality of sensing information commonly include the reference identifier and the continuous identifier Number field 1950, and the number of '3' is written in the identifier number field 1930, the entire length of the sensing data can be reduced.

Another method of reducing the length of the entire sensing data is to record a serial number indicating the number of consecutive identifiers sequentially from the reference identifier in addition to the setting of the reference identifier as a reference in the identifier information field 1950 .

That is, in the above method, the number of consecutive identifiers based on the reference identifier and the reference identifier may be recorded in the identifier information field 1950.

For example, if the reference identifier set in field 1950 is '/ soil / 1 / ec' and the set serial number is '3', the sensing value set in the sensing value field 1970 is '/ soil / 1 / ec' / soil / 1 / temp ', and' / soil / 1 / hum '.

That is, each identifier ('/ soil / 1 / ec', '/ soil / 1 / ec') continuously set by a serial number (for example, '3' / 1 / temp ',' / soil / 1 / hum ') is included in the sensing value field 1970.

In this way, the actual sensing data includes sensing information corresponding to identifiers of '/ soil / 1 / ec', '/ soil / 1 / temp', and '/ soil / 1 / hum' / Soil / 1 / ec 'without writing the identifiers (' / soil / 1 / ec ',' / soil / 1 / temp ',' / Soil / 1 / ec ',' / soil / 1 / temp ', and' / soil / 1 / ec 'are recorded in the sensing data by recording the serial number / soil / 1 / hum 'is included.

By doing so, the overall length of the sensing data can be reduced.

However, if another method of reducing the length of the entire sensing data is used, the value of the identifier number field 1930 will be 'null'. As described above, according to the embodiment of the present invention, The structure of the sensing data transmitted /

Hereinafter, another embodiment of the sensing data format received by the sensing data collecting apparatus 200 according to the present invention will be described.

In the embodiment of the sensing data collection method described below, it is assumed that the format of the sensing data is a JSON (JavaScript Object Notation) format.

Here, the JSON type is an open standard format that uses human-readable text to convey data objects consisting of attribute-value pairs.

It is a major data format that largely replaces the Extensible Markup Language (XML) for asynchronous browser / server communication.

In particular, it is known as a way of expressing the data when exchanging data on the Internet.

There is no particular restriction on the type of data, and it is particularly suitable for representing variable values in computer programs.

It is inherently derived from the JavaScript language and follows the syntax of JavaScript, but is a language-independent data format.

This means that the code for parsing and generating JSON data is easily available in many programming languages, including C, C ++, C #, Java, JavaScript, Perl, and Python, because it is programming language and platform independent.

The official Internet media type of JSON is 'application / json', and the file extension of JSON can be '.json'.

In another embodiment, the sensing data represents at least a part of at least one identification component included in the identifier as a path item, and is expressed as a value item by matching the remaining identification component of the identifier with the sensing information .

That is, for example, the sensing data format according to the present embodiment is

{

"DeviceId": <device identifier>

"Values": [

{

"Time": <measurement date>,

"Path": <at least a part of one or more identification components included in the identifier>

"Value": <sensing value>

}

...

]

}

Can be expressed as

In order to facilitate understanding of the present invention, some examples will be described. In the case of transmitting the EC value of the first soil sensor

"Values": [

{

"Time": "2015-06-12 13:22:33"

"Path": "/ soil / 1 / ec"

"Value": 0.04

}

]

And when three values (EC, temperature, humidity) of the first soil sensor are transmitted,

"Values": [

{

"Time": "2015-06-12 13:22:33"

"Path": "/ soil / 1"

"Value": {

"Ec": 0.04

"Temp": 23.1

"Hum": 22.4

}

]

The sensing values corresponding to a plurality of identifiers can be grouped together and transmitted.

In addition, when a plurality of sensing values are grouped and transmitted by a user's setting or the like, data that is not used may be transmitted. In such a case, the data transmission mode is as follows.

"Values": [

{

"Time": "2015-06-12 13:22:33"

"Path": "/ soil / 1"

"Value": {

"Ec": 0.04

"Hum": 22.4

}

]

The above example is an example of transmitting only the ec and the humidity value among the three values defined in the No. 1 soil sensor.

In addition, when the soil sensor values 1 and 2 are transmitted,

"Values": [

{

"Time": "2015-06-12 13:22:33"

"Path": "/ soil"

"Value": {

"One":{

"Ec": 0.04

"Temp": 23.1

"Hum": 22.4

}

"2":{

"Ec": 0.038

"Temp": 27.2

"Hum": 24.3

}

]

/ Soil " (identification component indicating the soil sensor), which is an identifier including an identification component common to the path item in the form of EC (Eclectric) of the soil sensor 1 and the soil sensor 2, Conductivity, temperature, and humidity values can be transmitted by matching sensing information to a value item.

That is, it is possible to map the sensing information corresponding to each identifier to each identifier, and send it. However, in such a case, when a large amount of sensing information is transmitted, a problem arises that the length of sensing data becomes excessively long. By transmitting the sensing data in the form of the example, there is an advantage that the length of the sensing data can be reduced.

In other words, the sensing information included in the sensing data is compressed and recorded by using an identifier having a hierarchical structure without mapping each sensing information to each identifier, thereby reducing the length of the sensing data will be.
