2. Description of the Related Art With the recent boom in hot springs, many springs have been developed. For example, according to the data of the Environment Agency in March 1997, there were 17,170 wells and 8,295 unused wells being developed in Japan. Books are increasing. About 500 new wells have been applied each year in recent years. Many conventional wellheads were mainly shallow wells intended for water sources warmed by magma in volcanic terrain, but recently, the same large drilling rigs used for oil drilling have used The ability to drill 2,000 m deep wells in a relatively short time has allowed hot springs to be found in areas unrelated to volcanic areas. This is due to the fact that the ground temperature increases as the depth goes deeper (generally, it increases by 3 degrees when the depth is 100 m). For example, the ground temperature at a depth of 1,500 m becomes about 60 degrees, so if there is a geological structure that stores groundwater, Can be a source. Further, recently, wells with a depth exceeding 2,000 m have been drilled, and the drilling depth tends to be deeper.

For example, according to the use of hot springs in fiscal 1995 by the Environment Agency, 2,508 hot spring resorts with accommodation facilities, 15,714 accommodation facilities using hot springs, and 1 user
Forty, 572,876 people, the amount of hot spring water is 2,504,700 liters per minute. In particular, recently, local governments have often built hot spring facilities for the purpose of welfare of residents, and as of November 1997, 2,015 local governments have facilities that use water sources.

[0004] In general, as the source of water is produced for a long period of time, the amount of hot water decreases, and the production equipment also deteriorates, so that it becomes necessary to drill a substitute well. Therefore, in view of the active use of hot springs in recent years, it is expected that many wells will be developed in the future and the number of excavations of deeper wells will increase.

[0005] Hot spring resources are limited resources and must be used effectively. For example, even if the source has high production capacity, if the amount of hot water that is actually used is rapidly pumped, the source will be immediately depleted, and valuable resources will be wasted. Also, even in the same hot spring area, the amount of hot water that can be produced and the expected total production amount differ for each source,
Normally, the amount used for each hot spring facility also differs. For this reason, managing the amount of hot water produced and used for each source would result in sources with excess hot water and hot spring facilities with insufficient water usage. become worse.

Therefore, recently, in order to maintain the productivity of the source for a long period of time and to stably supply hot water to the hot spring facility while securing an effective production amount, the production status of the source in the same hot spring area has been recently increased. A centralized management system for comprehensively and centrally managing the system has been introduced. Using such a system, a centralized management business has already been carried out in 117 hot spring resorts.

In such a centralized management system,
A management center for acquiring, managing, and analyzing various data of each source is provided, and data is collectively processed there. Data from each source is sent to the management center by wire or wirelessly. By analyzing these data, the management center can construct an optimal production plan and operate the facility.

By the way, recently, many houses with hot springs, which allow you to enjoy a hot spring bath while staying at home, have been sold to individuals in hot spring resorts, and are attracting much attention. In such a house, the hot spring water is drawn from the source separately from the water source by a dedicated hot water supply pipe, and a water meter is installed, and meter readers periodically patrol and check the amount of hot water used by each house. I have.

[0009]

However, the above-mentioned conventional centralized resource management system has the following problems.

(1) A management center as a fixed base is required, and the construction thereof requires a large amount of capital.

(2) A plurality of persons cannot monitor the source at different places at the same time. In order to ascertain the status of the source at a location different from the management center, it is necessary to transmit data obtained at the management center to another location, which inevitably causes a time delay.

(3) In order to enable prompt communication and handling in the event of an abnormality, it is necessary to allocate personnel for constantly monitoring the source abnormality.

(4) When the sources to be managed are distributed over a wide area, a management center is set up for each area, and a dedicated computer is provided for each management center. In this case, it is necessary to periodically improve the capabilities of those computers and application programs used therein. Therefore, personnel and training required to manage and operate the computer are required.
Further, when it becomes necessary to add data to be measured, a new investment such as a change in an application program is required.

(5) It takes a lot of time to create a report on the production status and the like for each source, and the burden on the administrator is large. In particular, if you want special data analysis or analysis,
Therefore, a data analysis program and the like are required, and further investment is required.

Of course, it is important for the owner of a source not being managed by the above-mentioned centralized management system to monitor the production status of each source.
However, building a full-fledged source data management system required significant investment, especially for owners of a small number of sources, making such investments extremely inefficient.

Further, when supplying hot spring water to a house with a hot spring as described above, the source owner or supplier must regularly check the amount of hot water used in each house by requesting a meter reader or the like. This requires time and effort, and it is difficult to reduce management costs.

The above problems are not only related to hot spring water in a hot spring area such as source management and meter reading management of hot water used in a house with a hot spring, but also in other fields, for example, the amount of water produced in a normal industrial well. It also exists in the case of managing water consumption, or in the case of managing meter reading of the amount of water used for water supply in a general residential house in a local area. Furthermore, even when the production target and the handling target are liquids and gases other than water,
Similar problems can occur.

The present invention has been made in view of such a problem, and has as its object to provide a data acquisition apparatus capable of efficiently collecting and managing measurement data obtained by measuring various physical quantities at low cost. Another object of the present invention is to provide a data acquisition device, a data server and a data service system which enable efficient management of hot spring water and the like obtained from a source with a small investment and maintenance cost.

The server 5a of the service station 5
As will be described later, various data sent from the data acquisition device 3 are stored in a database for each of the companies A, B, and C, and are stored in response to a request from the terminal 6 of each company. It has a function of providing data stored in a company database as it is or after performing a predetermined process. The server 5a has a security function of requesting the presentation of a user ID, a password, and the like at the time of a data provision request. Not to provide
Even if a company employee does not qualify as a manager, we do not provide that company data. That is, unspecified third parties cannot browse the data, and the security of each company's data is maintained.

The public telephone network 1 includes an access point 2a,
2b and the like, it is connected to the Internet communication network 2. As is well known, the Internet communication network 2 is provided with a large number of access points by a provider (connection company), and the user makes a predetermined contract with the provider in advance, so that the public telephone network 1 and the high-speed An arbitrary access point can be accessed via the data communication network 4 or the like, and can be connected to the Internet communication network 2. In this case, the use of the public telephone network 1 and the contract concluded with the provider are usually charged, but there is no charge for the use of the Internet communication network 2 itself, and the access of the connected side (entrance side). No matter how far the point is from the access point on the other side (exit side), the usage fee is free. For this reason,
The costs required for communication are only the usage fee of the public telephone network 1 from each data acquisition device 3 to the nearest access point, the usage fee of the high-speed data communication network 4, and the connection fee paid to the provider. Therefore, if an access point of the Internet communication network 2 is set in advance for each data acquisition device 3 so that the line use distance in the public telephone network 1 is as short as possible, the distance between the service station 5 and each data acquisition device 3 is set. Regardless, the communication cost is almost constant and extremely low. This is the same when accessing the service station 5 from the terminal 6 of each company. Here, the Internet communication network 9 corresponds to the "wide area communication network for computers" in the present invention, and the access points 2a and 2b correspond to the "connection points" in the present invention.

Although a sensor is used, another sensor may be used. Further, a plurality of types of water quality sensors may be provided. The reason for detecting the current value of the pump 101 is that various mineral components and the like in the hot spring water gradually adhere to a driving portion and a flow path of the pump 101 as time elapses, thereby increasing the driving resistance. This is for monitoring the increase of the water supply pump 101 to know the time of overhaul or replacement of the water pump 101, thereby making it possible to prevent a trouble due to the damage of the water pump 101.

The input section 31 amplifies each input detection signal by an amplifier (not shown), and then amplifies the A / A signal (not shown).

The transmission / reception unit 33b performs a calling process and a call receiving process for the public telephone network 1, and includes a modem and the like. The communication unit 33 transfers the measurement data periodically input from the data acquisition unit 32 to the server 5a via the public telephone network 1, the Internet communication network 2, and the high-speed data communication network 4. I have.

The control unit 34 controls the entire operation of the data acquisition device 3A (1), and has a clock unit 34a capable of measuring the date, month, day, hour, minute, and second. The control unit 34 controls the data acquisition unit 3 based on the clock signal from the clock unit 34a.
2 controls the timing at which measurement data is acquired from the input / output unit 31 and the timing at which the data acquisition unit 32 sends measurement data to the server 5a via the communication unit 33. The control unit 34 also has a memory 34 for storing a threshold value and the like set by the user.
b. These threshold values are set for each type of measurement data, as described later, and define the normal range of each measurement data. A person with a specific qualification (source manager) of Company A can check the production status of the source on the browser screen of the display device 58 (FIG. 4) described later on the management terminal 6A (1) or the headquarters terminal 6A (2) of the company. In view of the above, each threshold value can be appropriately changed. The control unit 34 is registered in advance via the public telephone network 1 when data exceeding the threshold value is observed or when a power failure signal 38 is input from an uninterruptible power supply 37 described later. Pager that informs the source administrator of the data abnormality or the occurrence of a power outage, and transfers all untransmitted measurement data acquired at that time to the public telephone network 1, Internet communication network 2, and high-speed data communication. The data is transferred to the server 5a via the network 4. The memory 34b stores a user ID and a device ID which are unique information of the data acquisition device 3A (1) itself.

The power supply unit 35 is connected to the uninterruptible power supply 37 and receives power supply therefrom. In the normal state, the uninterruptible power supply 37 supplies electric power from a commercial power supply (not shown) to the power supply unit 35 of the data acquisition device 3A (1), and at the time of a power failure, outputs a power failure signal 38 to the data acquisition device 3A (1). To the control unit 34 of
The power stored in the built-in battery is supplied to the power supply unit 35. Here, the uninterruptible power supply device 37 corresponds to the “power supply device” in the present invention.

Control for displaying on the display device 68 or outputting to the printer 69 is performed.

Next, the operation of the data service system having the above configuration will be described with reference to FIGS.
Here, FIG. 7 mainly shows the operation of the control unit 34 in the data acquisition device 3, FIGS. 8 and 9 show the operation of the server 5a, and FIGS.
The display example of the browser screen on the display device 58 of (1) is shown. FIG. 7 shows the data acquisition device 3 of Company A.
The operation of A (1) will be described, but the same applies to the other data acquisition devices 3.

First, referring to FIG.
The main operation of A (1) will be described.

The control unit 34 of the data acquisition device 3A (1)
The arrival of the data acquisition time is monitored based on the clock signal from the clock unit 34a (step S101). As a result, when the arrival of the data acquisition time is confirmed (step S101;
Y), the control unit 34 controls the data acquisition unit 32 to acquire the flow rate, water quality, temperature, pump current, and water level measurement data from the input unit 31 and record them in the memory 32a (step S102). . Note that the data acquisition cycle (data sampling cycle) in this case is determined in advance in the memory 34.
b, and is set to, for example, about 1 minute as described above. However, the data acquisition cycle can be changed by transmitting a measurement data acquisition cycle change request from the company A terminal 6A to the server 5a, as described later.

Here, the control section 34 reads out each measurement data stored in the memory 32a and determines whether or not they are in a normal range (step S103). This determination is made by comparing each read measurement data with a threshold value for each data type stored in the memory 34b. These thresholds can be changed by transmitting a threshold change request from the company A terminal 6A to the server 5a, as described later.

The control unit 34 compares each measurement data with the corresponding threshold value. If no abnormality is detected for any of the data types (step S
103; N) Further, it is checked whether or not a power failure signal 38 is input from the uninterruptible power supply 37, and the power failure signal 3
8 has not been input (step S104;
N) Further, it is checked whether or not the periodic report time has arrived based on the clock signal from the clock section 34a (step S10).
5). As a result, if the periodic report time has not yet arrived (step S105; N), the process returns to step S101 and waits for the next data acquisition time to arrive. Thereafter, steps S101 to S101 are performed until the regular report time arrives. The process of S105 is repeated. The period at which the periodic report is performed is registered in the memory 34b in advance.
Set every hour. However, as described later, this periodic reporting cycle can be achieved by transmitting a periodic reporting cycle change request from the company A terminal 6A to the server 5a.

On the other hand, if the regular report time has come in step S105 (step S105; Y),
The control unit 34 controls the data acquisition unit 32 to read out the untransmitted measurement data stored in the memory 32a of the data acquisition unit 32, and passes it to the communication unit 33 (Step S1).
06). If the periodic report cycle is 4 hours as described above, the measurement data for the untransmitted data becomes the measurement data for 4 hours. The communication unit 33 performs a predetermined call process (line connection process) in accordance with an instruction from the control unit 34,
The measurement data passed from the data acquisition unit 32 is transmitted to the server 5a via the public telephone network 1, the Internet communication network 2, and the high-speed data communication network 4 (Step S10).
7). Here, the user ID and the device ID stored in the memory 34b are read and used for the calling process.

In step S103, if any of the types of measurement data obtained from the input / output unit 31 exceeds the threshold, the control unit 34 determines that the data is abnormal (step S103; Y). Then, the data acquisition unit 32 is controlled to read out all untransmitted measurement data at the time of occurrence of the abnormality from the memory 32a of the data acquisition unit 32 and pass it to the communication unit 33 (Step S108). Communication unit 33
Performs a predetermined call process (line connection process) in response to an instruction from the control unit 34, and converts the measurement data passed from the data acquisition unit 32 into a message (hereinafter, referred to as a message) for reporting the occurrence of a data abnormality. The data is transmitted to the server 5a via the public telephone network 1, the Internet communication network 2, and the high-speed data communication network 4 (step S109). The control unit 34 further controls the communication unit 33 to report the occurrence of the data abnormality to the source manager of the company A specified in advance (step S110). This notification is made, for example, by registering in advance the telephone number of the pager or mobile phone owned by the source administrator of Company A in the memory 34b, and when the data abnormality occurs, the control unit 34
This is done by reading out the telephone number of this report destination and automatically dialing. The telephone number of the report destination can be changed by transmitting a report renewal request from the company A terminal 6A to the server 5a, as described later.

In step S104, when it is detected that the power failure signal 38 is input from the uninterruptible power supply 37 (step S104; Y), the control unit 34
Determines that a power failure has occurred and controls the data acquisition unit 32 to
All the untransmitted measurement data at that time are read from the memory 32a of the data acquisition unit 32 and passed to the communication unit 33 (Step S111). The communication unit 33 performs a predetermined calling process (line connection process) in response to an instruction from the control unit 34, and converts the measurement data passed from the data acquisition unit 32 into a message for reporting occurrence of a power failure (hereinafter referred to as a message). , A power failure message.), The server 5a via the public telephone network 1, the Internet communication network 2, and the high-speed data communication network 4.
(Step S112). The control unit 34 further controls the communication unit 33 to report the occurrence of a power failure to a pager, a mobile phone, or the like possessed by a source manager of Company A specified in advance (step S113).

Next, main operations of the server 5a will be described with reference to FIGS.

When the communication device 51 of the server 5a receives a connection request from any of the data acquisition devices 3 or the terminal 6 via the Internet communication network 2 and the high-speed data communication network 4 (step S201; Y), the CPU 52 Then, it is determined whether the access is from any of the data acquisition devices 3 or from any of the terminals 6 (step S202). As a result, if the access is from the data acquisition device 3 (step S202;
Y), the CPU 52 prompts the other party to transmit the user ID and the device ID, and when these IDs are transmitted, checks them (step S203). As a result of this check, if the user ID and the device ID are appropriate (step S204; Y), the CPU 5
2 transmits the data transmitted subsequently to the communication device 51
(Step S205), and this is
5 is recorded in the corresponding area (see FIG. 5) in the database 55a (step S206). In this case, the received data includes measurement data sent periodically,
It includes measurement data and a data abnormality message sent when an abnormality occurs, and measurement data and a power failure message sent when a power failure occurs. For example, when each measurement data of temperature, flow rate, water level, water quality and pumping current is received from the data acquisition device 3A (1), the CPU
Numeral 52 accumulates the received measurement data in each corresponding area of the equipment number 1 of the well number 1 of the company A in the database 55a shown in FIG.

On the other hand, if the result of determination in step S203 is that access has been from any terminal 6 (step S202; N), the CPU 52
Is transmitted by the communication device 51 (step S207). The homepage data is sent to the terminal 6 that has made the access request via the high-speed data communication network 4, the Internet communication network 2, and the public telephone network 1, and displayed on the browser screen of the display device 68 (FIG. 6). You.

Here, it is assumed that the terminal 6 that has made the access request is, for example, the management terminal 6B (1) of Company B. When "source monitoring system" is selected from a homepage menu (not shown) displayed on the browser screen of the display device 68 of the management terminal 6B (1), a command for requesting transmission of source monitoring data is sent to the Internet. It is sent to the server 5a via the communication network 2 or the like (Step S208; Y). Upon receiving the request, the CPU 52 of the server 5a urges the other party (here, for example, the management terminal 6B (1)) requesting the access to transmit a user ID and a password, and when these IDs are transmitted. Is checked (step S209). As a result of this check, user I
If D and the password are correct (step S210; Y), the CPU 52 reads the initial screen data of the source monitoring system from the HDD 55, and sends it to the management terminal 6B (1) via the Internet communication network 2 or the like. It is sent (step S211). This initial screen is displayed on the browser screen of the display device 68 of the management terminal 6B (1).

FIG. 10 shows the display device 6 of the management terminal 6B (1).
8 shows the initial screen of the source monitoring system displayed on the browser screen of FIG. As shown in this figure, the initial screen includes a title indicating the source monitoring system and the like.
The well numbers "1" to "3" of the wells owned by the company are displayed. When any well number is clicked and selected by the mouse 67 on this screen (step S21 in FIG. 9).
2; Y), the selected well number is sent to the server 5a. Upon receiving this, the CPU 52 of the server 5a
The data relating to the requested well number is read out from the database 55a of the server 55 and transmitted to the management terminal 6B (1) together with the screen data for data display (step S21).
3). This data includes, in addition to the measurement data, data for notifying the status of a data abnormality or a power failure. These data are received by the management terminal 6B (1) and displayed on the browser screen of the display device 68.

FIG. 11 shows an initial screen for data display displayed on the browser screen of the display device 68 in the management terminal 6B (1). As shown in this figure, the initial screen for data display includes the well number, production date and time, well depth, well position (east longitude and north latitude), pumping pump installation depth, source manager, etc. Is displayed. In addition, in the example of FIG. 2, the pump is arranged on the ground. However, when the pump is installed in a well, the installation depth is displayed. Further, a process selection menu is displayed below these management data display areas. FIG. 11 shows an example in which the well number 1 of Company B is designated, for example. In this process selection menu, the 'display' button is used to display the specified measurement data as it is on the screen as numerical data.
The “Graph display” button is selected when the designated measurement data is graphed and displayed on the screen. The “set” button is selected when setting a threshold value as a reference for judging the normality of the measurement data acquired by the data acquisition devices 3B (1) to 3B (3).
The 'Cancel' button is selected when exiting this screen. 'Temperature', 'water volume', 'water level',
The "water quality" and "current" buttons are selected when displaying the temperature, flow rate, well level, hot spring water quality, and pumping pump current of the pumped hot spring water, respectively.

Here, when any process is selected from the process selection menu (step S214; Y), a command requesting the selected process is sent to the server 5a. The CPU 52 of the server 5a executes the requested processing (Step S215). Specifically, the server 5
The CPU 52a transmits the raw measurement data read from the database 55a of the HDD 55 as it is, analyzes the measurement data and transmits the analysis result, or displays and sets the threshold value of each measurement data. Do. As described below, the analysis process of the measurement data can be a batch process in addition to the real-time process.
When the "cancel" button is selected (step S216; Y), the CPU 52 of the server 5a ends the screen of the "source monitoring system" and sends out the homepage again (step S207).

For example, in the screen shown in FIG.
After selecting the three buttons "Temperature", "Water amount" and "Water level" and then selecting the "Display" button, as shown in FIG. The three types of measurement data of temperature, water amount and water level acquired by the data acquisition device 3B (1) are transmitted from the server 5a to the management terminal 6
It is sent to B (1) and displayed as numerical data along with the observation time.

On the screen shown in FIG. 11, when the three buttons of “temperature”, “water quantity” and “water level” are selected and then the “graph display” button is selected, as shown in FIG. Temperature T and water volume F obtained by the data acquisition device 3B (1) installed in the well No. 1 of Company B
The three types of measurement data of the water level L and the water level L are sent from the server 5a to the management terminal 6B (1), and are displayed as graph data together with the observation time.

Now, in step S208 of FIG.
When a line disconnection command is selected on the home page displayed on the display device 68 of the management terminal 6B (1) (step S217; Y), the line is disconnected and the server 5a provides data to the management terminal 6B (1). The service ends (step S218).

Next, an outline of the operation processing viewed from the user side, that is, the terminal 6 side will be described. Here, terminal 6
Is the management terminal 6B (1).

(I) In order for the source manager of the management terminal 6B (1) to monitor the measurement data acquired by the data acquisition device 3B and stored in the server 5a, first, a home page provided by the server 5a is provided. Access and select 'Source Monitoring System' from the menu displayed. Here, if the user ID and password are input, the management terminal 6B
(1) is the monitoring center.

(Ii) For example, in a case where Company B owns a plurality of wells and the setting is made so that these wells can be monitored, the source manager may select the initial screen (FIG. 10). By selecting a plurality of well numbers displayed above and opening a plurality of browser screens, a plurality of wells can be monitored simultaneously.

(Iii) The measurement data acquired by each data acquisition device 3 is sent to the server 5a at regular intervals and sent to the HDD 5
5, when an access request is made from the management terminal 6B (1), the latest measurement data taken into the database 55a is read out and read from the management terminal 6B (1). Will be sent to Therefore, the latest measurement data is always displayed on the default data display screen shown in FIG. Here, for example, the periodic reporting cycle from each data acquisition device 3B to the server 5a is set as short as possible, and high-speed data communication is performed between the time management terminal 6B (1) and the Internet communication network 2 instead of the public telephone network 1. If the connection is made by a dedicated line such as the network 4, the data acquisition device 3B (1) to the management terminal 6B (1)
It is also possible to monitor the latest data acquired in 3B (3) almost in real time. However, such a monitoring method is also possible when connecting to the public telephone network 1 via a modem instead of a dedicated line, but in this case, a telephone line usage fee is charged according to the connection time. .

(Iv) Further, for example, on the browser screen shown in FIG. 11, by selecting the “setting” button, a setting menu (not shown) is displayed, and a predetermined setting command is selected from the setting menu. Setting and changing of the threshold value for each measurement data type, the data acquisition cycle in each data acquisition device 3, the data acquisition device 3 to the server 5a
You can change the period of the regular reporting to As a result, it is possible to flexibly cope with a change in the source status or a change in the source manager. For example, when it is necessary to analyze long-term data movement, it is appropriate to set a large data acquisition cycle in each data acquisition device 3.

(V) On the graph screen shown in FIG.
'Zoom In' button B1 or 'Zoom Ou'
By operating the t 'button B2, the length of the time axis (horizontal axis) of the graph and the display width of the graph can be arbitrarily set. For example, by operating the “Zoom In” button, minute changes can be monitored, while “Zoom In” can be monitored.
By operating the m Out 'button, it is possible to increase the time interval and to know long-term trends. By specifying the date and time on the screen, data in an arbitrary time zone can be displayed.

(Vi) On the browser screen (for example, FIG. 12) of the display device 68 of the management terminal 6B (1), the menu bar M
Is selected, and a data analysis command is selected, thereby requesting the server 5a to analyze various statistical processes and the like based on the measurement data accumulated in the database 55a. be able to. In this case, when the analysis processing takes a long time, the batch processing mode can be selected instead of the real-time processing mode. In this batch processing mode, after requesting the server 5a to execute the analysis processing, the management terminal 6B (1) is once disconnected from the public telephone network 1 and waits for the completion of the analysis processing in the server 5a. In this mode, the requested analysis result can be obtained by accessing 5a.

(Vii) On the browser screen (for example, FIG. 12) of the display device 68 of the management terminal 6B (1), select “File” in the menu bar M and select a print command in the menu bar M to display the screen. The measurement data displayed in a graph, the measurement data displayed in a numerical table format, and the analysis result data can be printed out by the printer 69 (FIG. 6). Further, by selecting “File” on the menu bar M and selecting a save command therein, the measurement data and the analysis result data displayed on the screen can be saved as a numerical data file. of course,
Printout of these data displayed on the browser is also possible.

(Viii) On the browser screen shown in FIG. 13, by selecting “View” in the menu bar M and selecting a threshold display command in the menu bar, the current threshold is displayed on the screen data. They can be displayed in layers. As a result, the situation of the well can be grasped at a glance, and it becomes possible to anticipate an abnormal situation at the source.

(Ix) When a data error occurs, a notification of the occurrence of the data error is sent to the pager or mobile phone held by the source manager, and a notification to that effect is sent to the server 5a. And transmission of measurement data. In response to this, on the browser screen of the display device 68 of the management terminal 6B (1), an alarm indicating the abnormality is displayed, and data until the occurrence of the abnormality is displayed. Thus, the source manager can also estimate the cause of the abnormality from the displayed data. Further, when the water pump 101 (FIG. 2) or the like stops due to an accident such as a power failure, the data acquisition device 3 is backed up by the power supplied from the uninterruptible power supply 37, and a power failure message is sent to the server 5a. This message is also sent to the management terminal 6B (1) and is displayed on the browser screen of the display device 68 as an alarm. At the same time, a power failure report is also sent to a pager or the like owned by the source manager. As a result, the source manager can immediately know the occurrence of the abnormality and its cause.

In the above description, a case is described in which the source administrator having a user ID and password registered in advance of Company B accesses the server 5a from the management terminal 6B (1) and monitors the source of the company. However, as long as the source manager can connect to the Internet communication network 2, any other terminal (for example, the head office terminal 6B (2) in FIG. 1) can be used.
) Can access the server 5a.
Of course, it is also possible to access using a mobile computer (movable computer). Similarly, the source managers of Company A and Company C can also use their own data in the database 55a of the server 5a using any terminal that can connect to the Internet communication network 2 as long as they have a pre-registered user ID and password. Can be accessed. On the other hand, the user I registered in advance
If you do not have D and a password,
The data of the server 5a cannot be accessed.

As described above, according to the data service system of the present embodiment, a function of measuring various physical quantities related to sources scattered in various places to acquire measurement data and communicating via the Internet communication network 2. And a function of receiving and storing measurement data transmitted from the data acquisition device 3 via the Internet communication network 2 and providing the stored measurement data via the Internet communication network 2 Server 5a having
The source manager can access the server 5a from the terminal 6 via the Internet communication network 2 to obtain necessary measurement data and monitor the status of the source. In this case, the source owner installs various sensors and the data acquisition device 3 in or near the well of the source and prepares a very common computer used for accessing the server 5a, and manages the data. A system can be constructed, and monitoring of the source and optimal production planning can be performed. Therefore, especially for source owners who own only a few sources, there is no need to build a large data management system including a management center, and a large investment is not required.
It is advantageous.

Further, according to the data service system of the present embodiment, data relating to a plurality of sources is stored in the server 5a.
It is also possible to collect and analyze data at a time, and by performing such analysis at regular intervals, the production status of the source can be grasped with high accuracy, and the source can be depleted and the temperature or water quality of the hot spring water can be monitored. It is also possible to predict such abnormalities in advance. For this reason, it is also possible to take measures such as performing production adjustment before an abnormal situation becomes apparent. Therefore, the present system is extremely useful for managing and protecting hot spring resources on a macro basis.

Further, according to the data service system of the present embodiment, the data acquisition device 3 and the server 5a can be connected to each other by using the Internet communication network 2, so that the data acquisition device 3 and the server 5a Even if communication is performed quite frequently between the users, the communication cost borne by the user (source owner) can be extremely reduced. That is, the user uses the line usage of the public telephone network 1 between each data acquisition device 3 and each of the nearest access points in the Internet communication network 2 and the nearest access in the user's terminal 6 and the Internet communication network 2. Only the line usage of the public telephone network 1 between the point and the point needs to be borne. For this reason, even when the data acquisition devices 3 are distributed over a wide area and are located at a considerably remote location from the server 5a, each data acquisition device 3 and the server 5
a, and communication costs between the terminal 6 of each user and the server 5a can be extremely low. For example, it is also possible to centrally manage all data acquired by a large number of data acquisition devices of each company installed in remote hot spring areas such as Hokkaido, Tohoku or the Kyushu region, for example, on a server 5a provided in Tokyo. Become. Furthermore, it is also possible to install a data acquisition device at the source of an overseas hot spring resort and to centrally manage the acquired data in the server 5a provided in Japan at a low cost.

Further, according to the data service system of the present embodiment, in the event of an emergency such as a data error or a power outage, an error notification is immediately sent directly to the pager of the source manager. Quick response to the situation is possible. Also, the source manager does not need to be resident at the terminal 6.

Further, in the data service system of the present embodiment, the user does not need to have a management center as a fixed base, and can connect from anywhere (for example, from abroad) as long as there is a terminal connectable to the Internet communication network 2. Also)
The data can be monitored by accessing the server 5a. Moreover, if a plurality of source managers are registered, each person can individually access the server 5a via the Internet communication network 2, so that a plurality of source managers can monitor the source at the same time. it can. There is no limit on the number of people who can register. Therefore, unlike the related art, there is no need to transfer the data obtained at the management center to another source manager at another place, and there is no time delay due to such transfer work. On the other hand, since a person other than a registered person cannot access the server 5a to acquire data, it is possible to prevent data from being viewed by unauthorized employees or from viewing company data by other companies.
