Problems solved by technology
[0008] In the prior art described above, the accuracy of the data output by the sensor cannot be guaranteed
For example, it is not possible to check whether a normal operation test has been performed for many installed sensors
In this case, if a sensor of a non-certified manufacturer or the like that has not undergone a predetermined certification inspection (operation test) is installed in the installation area, the accuracy of data obtained by collecting sensor information will deteriorate.
[0009] In addition, the reliability of sensor data accuracy, durability, etc. may vary for each manufacturer.
Therefore, after the sensor is installed, the operation status of the sensor cannot be grasped in actual operation, and the evaluation of the sensor cannot be performed.
In addition, when sensors from multiple manufacturers are mixedly installed in the installation area, it is not possible to implement management processes such as evaluation by manufacturer and allocation of usage costs associated with sensor operation for each manufacturer based on the evaluation results.

[0025] (Configuration of data processing device)
[0026] Hereinafter, preferred embodiments of the disclosed technology will be described in detail with reference to the drawings. figure 1 It is a figure which shows the installation state of the sensor installed in the data network concerning embodiment. Such as figure 1 As shown, a plurality of chip-shaped sensor nodes (data processing devices) 101 are installed in a predetermined installation area A. As shown in FIG.
[0027] And, if figure 1 As shown, in the installation area A, sensor nodes 101A, 101B, and 101C manufactured by different manufacturers (manufacturers) are mixedly installed. Also, in the installation area A, a parent node (data aggregator, aggregator) 102 that receives sensor outputs of a plurality of sensor nodes 101 by wireless or the like is installed.
[0028] The sensor node 101 detects a predetermined amount of displacement at each installation position in the installation area A, and transmits the...

In a plurality of data processing devices (101) disposed in the setting area (A) to the data network management device (130) transmit data to the data network management system, the data processing device (101) is processed together with its own identification information to the data network management device (130) is transmitted. The data network management device (130) based on the identification information of the data processing device (101) that has completed the prescribed certification inspection, and the identification information obtained from the data processing device (101) after the setting to the setting area (A), to determine the data processing device (101) of the data acquisition object.
Description
technical field [0001] The invention relates to a data network management system, a data network management device, a data processing device and a data network management method for managing a data network. Background technique [0002] It is conceivable to install many sensors in the installation area, for example, hundreds to tens of thousands of cheap chip-shaped sensors (data processing devices), and wirelessly transmit the detection information detected by each sensor, and collect the detection information through the upper-level parent device Information technology for data network. In the case of using many sensors to achieve wide-area performance and coverage, it is necessary to install an enlarged number of sensors (nodes). [0003] In addition, the processing performance of a sensor operating with a collection device (for example, energy changes such as light, vibration, temperature, and radio waves as the external environment at the installation location) as a po...
