Description

Detailed Description of the Invention

[0001]

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

[0002]

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

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

Further, when the measurement site and the place for analyzing and processing the measurement data are distant from each other, it is necessary to construct a data communication system for exchanging data between them.

Further, in processing and managing the measurement data,
When adding a new function or deleting an existing function,
The user must individually change the associated application software.

Furthermore, in addition to these general problems, there are problems specific to each measurement target in a specific measurement target. For example, at the site of construction / civil engineering, environmental data such as noise and vibration generated by the construction must be continuously measured and recorded, but it is not possible to manage the measured data at multiple sites individually. It is complicated.

In managing buildings and factories, daily data, weekly data, and various data on electricity, gas, water and sewage, etc.
Multi-faceted data processing such as monthly and annual reports is required, and it is inevitable that a considerable number of man-hours will occur regularly.

[0008] At each distribution stage from the production of various foods such as frozen and chilled products to the sale to general consumers, the inside of a freezer or a refrigerator that freezes and freezes the products at each stage as one of quality control data. In addition to measuring and recording the temperature transition state, the operation status of the compressor is individually measured and recorded as maintenance data for equipment. When an abnormality occurs in a product, the recorded data is also one of the means for clarifying the cause, but it is difficult to unify the measurement data of all processes from upstream to downstream under the condition of individual management. Is.

In managing various greenhouses, environmental data such as indoor / outdoor temperature / humidity / carbon dioxide / sunlight time, data on fertilizing component analysis / fertilization amount / soil PH, cultivation / water supply / boiler operation, etc. It is desirable to record and store various data such as history and data related to operations such as the amount of electricity, analyze the correlation with the growth transition data of the cultivation target and the shipment amount data, and feed it back to the actual work. It is difficult in terms of man-hours to do everything from actual greenhouse cultivation work to data analysis work.

In the simple water supply business and agricultural water business,
Various data such as water level, flow rate, pump operating status monitoring, etc. are recorded and stored, but since the business scale is relatively small, the measurement data file also becomes small,
If the person in charge changes, the measured data may be scattered.

The applicant of the present invention has disclosed a measurement data management system for solving such a problem in Japanese Patent Laid-Open No. 2002-817.
No. 9 (hereinafter referred to as prior invention) is proposed.

The field server 90 constituting the measuring device 30 comprises a transmission control section 91, a measurement condition control section 92, a measurement data calculation section 93, a measurement data memory 94 and the like.

The field server 90 fetches the measurement data of the measurement sensor 60 converted and output from the A / D converter 71 of the field control device 70 into the measurement data memory 94 in a text data format at a cycle of, for example, 2 seconds, and performs this measurement. The measurement data stored in the data memory 94 is periodically (for example, every 2 hours) PPP-connected to connect to the data center 5.
Send to 0.

The user is required to use the measuring device 3 which is suitable for the purpose of measurement.
0 is installed at the measurement site so that the measurement data of the desired measurement object can be obtained, and those measurement data
It is set to be transmitted to a predetermined data center 50 via 0.

As a mode of data transmission to the data center 50, when the measurement sensor 60 has an upper and lower limit alarm setting function for the measured value, the measured value exceeds the alarm set value, and then It is also possible to send measurement data.

In this case, as the data center 50,
By using the mail function, it is possible to notify the required department or person in charge of the user of which measurement value of the measurement sensor indicates an abnormal value by mail. Furthermore, a trend recording screen of measured values before and after that may be generated and attached as necessary, or the address of the screen may be notified to prompt confirmation on the web.

The data center 50 has a user authentication section 5
3, a WWW server 51, a data server 52,
A measurement data processing / editing unit 54, a user-specific processing history server 55, a setting management server 56, and the like are provided.

In the data center 50, predetermined user information such as an ID code and a password is registered in the user authentication section 51 so that the user terminal 40 can access it through a predetermined user authentication procedure. Then, the measurement data transmitted from the measuring device 30 via the Internet 10 is taken into the data server 52 and stored as a file for each user and each measuring device.

In addition, in the data center 50, the measurement data fetched by the data server 52 is processed and edited by the measurement data processing / editing unit 54 in response to the user's request for processing such as trend, daily report, weekly report, monthly report, annual report, totalization and alarm history. The processed and edited data is stored in the data server 52 separately with a proper file name. These processing requests from users are sequentially stored in the processing history server 55 for each user so that they can be referred to when necessary.

Further, in the data center 50, various setting management such as measurement condition data of each measuring instrument 30 and control setting condition data when a measuring instrument having a control function for a measuring object is used as necessary. The data relating to the above is sequentially stored in the setting management server 56 so that it can be referred to when necessary.

In such a structure, the user can obtain the measurement data processed in a predetermined data format such as trend, daily report, weekly report, monthly report, annual report, totalization, alarm history, etc., which he / she needs, when needed. HT from the data center 50 via the Internet 10 and the user terminal 40
It is available in ML-converted web format and can be viewed with a general-purpose web browser.

When the measurement value of the measurement sensor 60 shows an abnormal value, the mail function of the data center 50 causes
The department or person in charge of the user can know by mail which measurement sensor 60 shows an abnormal value.

[0028]

However, according to the prior invention, when the installation location of the measurement sensor 60 showing an abnormal measurement value is far away from the user's required department or the present location of the person in charge, it is prompt. Can not correspond to.

The present invention solves such a problem, and an object thereof is to provide measurement data that can be promptly dealt with even when a measuring instrument installed at a remote place from the user's present location shows an abnormal value. To provide a management system.
