Problems solved by technology

[0015] In this way, the measurement data sequentially sent from the sensor includes a lot of data whose value does not change in units of measurement items, but currently it is directly sent to the network and stored in the DB server table , so this is also a factor that increases the occupation of disk space and communication traffic in vain

Embodiment Construction

[0033] Such as figure 1As shown, the first data management system 10 according to the present invention includes a first AP node 12 , a second AP node 14 , a first DB node 16 , and a second DB node 18 .

[0034] However, the number of AP nodes and DB nodes is not particularly limited.

[0035] The first AP node 12 is connected to a first DB node 16 and a second DB node 18 via a network.

[0036] In addition, the second AP node 14 is connected to the first DB node 16 and the second DB node 18 via a network.

[0037] Here, an "AP node" refers to a computer on which a program for an AP (Application) server is installed.

[0038] In addition, the term "DB node" refers to a server computer on which a program for a DB (Database) server is installed.

[0039] However, each AP node and each DB node do not need to be constituted by physically independent computers (with independent AP addresses).

[0040] For example, multiple AP nodes or DB nodes can be configured by executing De...

Abstract

Reduces disk footprint by eliminating redundancy in measurement data detected by sensors. An AP node for connecting a plurality of sensors and a DB node for connecting to the AP node are provided; wherein, the AP node has: a device for receiving measurement data including a plurality of measurement item values ​​output from each sensor, A queue 30 for pre-storing the current value in units of measurement items of each sensor, a device for querying the queue 30 each time the measurement data is output from each sensor, and judging whether the value of each measurement item changes, used for when the measurement item When the value of the measurement item changes, the storage data containing the value of the measurement item is generated according to the measurement item, and sent to the device of the DB node, and the device for overwriting the current value in the queue 30 according to the latest value of the measurement item; DB The node includes a plurality of tables for storing numerical values ​​included in the measurement data for each measurement item of each sensor, and means for storing storage data transmitted from the AP node in the corresponding table.

Description

technical field [0001] The present invention relates to a data management system, and more particularly to a technique for efficiently storing measurement data sent from a plurality of sensors. Background technique [0002] With the advent of the so-called IOT (Internet of Things), in which everything is connected through the Internet and creates new value, a large amount of measurement data output from various sensors is continuously pouring into servers on the network. [0003] [Non-Patent Document 1] [0004] IoT: Internet of Things (Internet of Things) [0005] Internet address: [0006] https: / / mono-wireless.com / jp / tech / Internet_of_Things.html [0007] Date retrieved: April 24, 2017 [0008] Figure 12 It is described that measurement data is periodically uploaded from multiple sensors (sensor A20, sensor B21, sensor C22) installed in various places to the AP server 80 installed on the Internet, and the DB management part 84 in the DB server 82 uploads it to The si...
