[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a measurement data management system, and more particularly, to a new system utilizing a network.

[0002]

2. Description of the Related Art In general, when collecting measurement data from an object to be measured, a user himself / herself constructs a measurement system according to an application, installs necessary measuring instruments at a measurement site, and transmits the measurement results to a user. It is being processed and stored by itself.

In this case, in order to browse the stored measurement data, special browsing software tailored to each measuring instrument is required.

[0004] When the measurement site and the place where the measurement data are analyzed and processed are far from each other, it is necessary to construct a data communication system for exchanging data between the two.

In processing and managing measurement data,
When adding new features or removing existing features,
Users must individually modify the associated application software.

[0006] Further, in a specific measurement object, in addition to these general problems, there are problems specific to each measurement object. For example, at construction and civil engineering sites, environmental data such as noise and vibration generated during construction must be continuously measured and recorded.However, it is not possible to manage measurement data at multiple sites individually. It is complicated.

[0007] In managing buildings and factories, daily data, weekly data, etc.
Multi-faceted data processing, such as monthly and annual reports, is required, and it is inevitable that a considerable amount of work will be required on a regular basis.

[0008] In each distribution stage from the production of various foods such as freezing and refrigeration to the sale to general consumers, as one of the quality control data, the inside of a freezer or a refrigerator for freezing and refrigeration preserving products at each stage. In addition to measuring and recording the transitional state of temperature, it has been practiced to individually measure and record the operating state of the compressor as equipment maintenance data. In the event that an abnormality occurs in a product, the recorded data is also one of the means for elucidating the cause, but it is difficult to unify the measurement data of all processes from upstream to downstream under the individual management. It is.

In managing various greenhouses, data on the environment such as indoor and outdoor temperature, humidity, carbon dioxide, sunshine time, data on fertilizer component analysis, fertilizer application, soil PH, etc., water supply / drainage, boiler operation It is desirable to record and store various types of data, such as data related to operations such as history and power consumption, and analyze the correlation with the growth transition data and shipping data of the cultivation target and feed it back to actual work. It is difficult to do all the work from the actual work of greenhouse cultivation to the analysis of these data by itself.

In the simple water supply business and the agricultural water business,
Various data such as monitoring of water level, flow rate and operation status of pumps are recorded and stored.However, since the business scale is relatively small, the measurement data file is also small,
If the person in charge changes, measurement data may be dissipated.

[0011]
