DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a technique for continuously observing the environment of an installation place of an object such as a cultural property or a building, and monitoring a change in the environment of the installation place at a remote place.

[0002]

BACKGROUND OF THE INVENTION Problems to be Solved by the Invention
Temperature, humidity, wind (wind direction, wind speed), sunshine duration, atmospheric nitrogen oxides (NO, NO ₂ , etc.) of the installation location of the object such as cultural properties and buildings that are constantly exposed to wind and precipitation
NOx), continuous measurement of environmental measurements such as sulfur dioxide (SO ₂ ) concentration in the atmosphere, precipitation, precipitation pH, etc.
Monitoring the progress of so-called atmospheric corrosion from observation data is performed. Considering the efficiency of personnel, cost, etc., a system that performs such monitoring makes observation unmanned,
It is desirable to be able to monitor many objects in one centralized location.

Conventionally, such observations themselves have been unmanned, but observation data is stored in a portable storage medium such as an MO (magneto-optical) disk by an observation device at the observation site, and is periodically hand-operated. The media was collected and delivered to the surveillance location, which required a great deal of labor.
In addition, since it took a considerable number of days for these observation data to arrive at the surveillance site, it was difficult to immediately understand the effects on the object when exposed to a severe environment such as a storm. . In some cases, such observation data was collected using communication lines.
Due to an increase in the number of objects to be managed, or when it is necessary to set up a monitoring place at a long distance from the objects,
There has been a problem that surveillance costs have risen with the use of communication lines.

An object of the present invention is to obtain data by continuously observing the installation environment of a large number of objects and to obtain the data in a short time.
By concentrating on monitoring locations at low cost, it is possible to efficiently monitor a large number of objects with a small number of monitoring locations.

FIG. 2 is a diagram showing a configuration of the installation environment observation device 1A of FIG. In the present embodiment, the first control unit 13 and the second control unit 1
However, since the observation by the continuous observation unit 11 is performed continuously, there is a possibility that the execution of each process in the apparatus cannot be performed in time by one control unit. It is provided for the purpose of preventing this.

In FIG. 1, a continuous observation section 11 continuously observes values relating to the environment at the place where the object is installed. In the present embodiment, the anemometer 21 is
A, 21B, anemometers 22A, 22B, a thermometer 23, and a hygrometer 24 are provided. The anemometer 22A measures the wind direction measured by the anemometer 21A, and the wind direction measured by the anemometer 21B. A total of 22B observe. Here, anemometer 2
1A is configured to output a pulse and output a larger number of pulses per unit time as the observed wind speed increases, while the anemometer 21B outputs a voltage and the observed wind speed is The output voltage is configured to increase as the value increases. The anemometer 22A is
4 bits (in the case of 16 azimuth expression) or 6 bits (in the case of 64 azimuth expression) called "Gray code"
The anemometer 22B is configured to output the wind direction corresponding to the analog voltage. The thermometer 23 and the hygrometer 24 are configured to output temperature or humidity in accordance with an analog voltage.

The observation section interface section 12 samples the observation data of the continuous observation section 11, converts the data into a digital value, and outputs the digital value to the first control section 13. In the present embodiment, it is necessary to reliably capture the instantaneous value of the wind environment (wind direction / wind speed) at the installation location of the object (in the case of a storm, etc.), and sampling is performed in consideration of the response of a general anemometer. Is set to 2 seconds, which is a value that can be sufficiently regarded as continuous observation of the wind environment. Accordingly, the pulse counter 25 outputs the number of pulses output by the anemometer 21A in 2 seconds as a digital value, and the sampling interval of the A / D (analog / digital) converter 26 is also 2 seconds. .

The first control unit 13 comprises a CPU (central processing unit) 27, a ROM 28, and a RAM 29.
7 according to the control program stored in the ROM 28,
While using M29 as a work area, control of the observation unit interface unit 12 and storage processing of continuous observation data in the storage unit 14 are performed.

The storage section 14 is written with continuous observation data by the first control section 13, and the written data is read by the second control section 15. First control unit 1
Since the control collision of the storage unit 14 between the third control unit 3 and the second control unit 15 may occur, the storage unit 14
0, and the priority of the memory access is given to the first control unit 13 having a small margin in the timing of the memory access because the continuous observation data needs to be written. With this configuration, it is possible to prevent loss of data at the time of writing observation data due to a control collision.

The second control unit 15 includes a CPU 31 and a ROM 3
2. Statistical analysis processing of continuous observation data read from the storage unit 14 using the RAM 33 as a work area in accordance with a control program stored in the ROM 32 by the CPU 31 in accordance with a control program stored in the ROM 32, and creation of an e-mail having the observation data as a text. A process of sending an e-mail obtained as a result of the process and the creation process from the network interface unit 16 to the installation environment monitoring device 2 via the communication network 3 is performed. Further, a process of collecting observation data by the observation device 7 from the device interface unit 17, a process of collecting observation data by the sub-environment observation device 4 from the sub-environment observation device interface unit 18, and an instrument operation state observation unit 19
To collect the observation data of the operation state of the continuous observation unit 11 and the observation equipment 7 by the computer.

The network interface unit 16 connects the installation environment observation device 1A to the communication network 3, and transmits the e-mail created by the second control unit to the communication network 3.
To be sent. The connection to the communication network 3 is not always necessary, and it is sufficient if the connection is made only when sending an e-mail. Therefore, the communication network 3
Even when the Internet is used, a further reduction in communication costs can be expected by performing a so-called dial-up connection in which the nearest Internet connection point intermittently connects to the Internet via a public telephone line network or the like. In this case, the network interface unit 16 includes a modem.

The equipment interface section 17 connects the observation equipment 7 such as an air pollution meter 34, an acid rain gauge 35, and a sunshine meter 36 to the installation environment observation apparatus 1A, and takes in observation data by the observation equipment 7. An interface matching the output interface of the device 7 is provided. In this embodiment, a general RS-232C
Use the interface.

Sub-environment observation device interface unit 18
Is for connecting the sub-environment observation device 4 to the installed environment observation device 1A and taking in the observation statistical data by the sub-environment observation device 4. In the present embodiment, a PHS (Personal Handy Phone System) terminal 37 and a PHS terminal interface 38 are connected to the sub-environment observation device interface 18.
And obtains observation data from the sub-environment observation device 4 using the terminal-to-terminal direct communication function normally provided in the PHS terminal, and sends the observation data to the second control unit 15. PHS is 32 kilobits /
Digital communication at a transmission rate of seconds is possible,
Explosive spread has led to cost reductions and can be obtained at low prices. The terminal-to-terminal direct communication function of a PHS terminal is a function of performing a direct communication between PHS terminals without passing through a PHS base station, and is also capable of performing data communication. By using a wireless transmission line for data transmission with the sub-environment observation device 4, a wired transmission line such as a communication cable is not required, so that installation costs are reduced and the influence on the landscape around the object is also reduced. It is possible to reduce it.

The instrument operating state observing section 19 includes the continuous observing section 1.
1 and a value relating to the operation state of the observation device 7 are observed, and the observed value is transmitted to the second control unit 15. In the present embodiment, the current consumption of each instrument of the continuous observation unit 11 and the observation device 7 is observed. Therefore, the A / D
A low resistance is inserted in series between the meter and the power supply, and the potential difference between both ends of the low resistance is A / D converted and output to the second control unit 15 as a digital value.

In this embodiment, the continuous observation unit 11
The anemometer 21A and the anemometer 22A have different output methods, but there is no problem in using either one of the anemometers. The observation unit interface unit 12 and the first control unit 13 may be made compatible with the output method of the anemometer so that the observation value can be obtained.

FIG. 3 shows the ROM 2 of the first control unit 13 shown in FIG.
8 is a flowchart of a control program executed by the CPU 27 stored in the CPU 8; FIG. 3 will be described with reference to FIG.

First, in step S101, data on the number of pulses output from the pulse counter 25 is obtained, and the number of pulses is converted into an observed wind speed. This conversion is anemometer 2
This is performed based on the specification of 1A.

In step S102, digital data output from the anemometer 22A is acquired and converted into a wind direction. The digital data output from the anemometer 22A is the above-mentioned gray code and needs to be converted to data indicating a normal direction. However, since this code differs depending on the anemoscope, the conversion process should be adapted to the anemometer to be used. To

In step S103, a digital value obtained by converting the voltage value corresponding to the observation data output from each of the anemometer 21B, the anemometer 22B, the thermometer 23, and the hygrometer 24 by the A / D converter 26 is obtained. Convert to wind speed, wind direction, temperature and humidity observations.

In step S104, step S101
The observation data obtained from to step S103 is stored in the storage unit 1
4 is stored in the dual port RAM 30. FIG. 4 shows a storage format of observation data in the dual port RAM 30. Each data is all 2-byte data,
In the same figure, the observation data of the anemometer 21A is stored for the wind speed 1; similarly, the anemometer 22A for the wind direction 1, the anemometer 21B for the wind speed 2, the anemometer 22B for the wind direction 2, and the thermometer 2 for the temperature.
3. For the humidity, six pieces of observation data of the hygrometer 24 are stored in the order of addresses in the processing of one cycle from step S101 to step S103. In the repetitive processing from step S101 to step S104 formed in step S105, data acquired in each cycle is sequentially stored.

In step S105, the dual port R
The elapsed time since the observation data was stored at the head address of the area for storing the observation data of AM30 is checked.
If it has exceeded 0 minutes, the process proceeds to step S106, while
Otherwise, the process returns to step S101, and the processes from step S101 to step S104 are repeated. By this process, observation data for continuous 10 minutes is stored in the dual port RAM. Here, the time of 10 minutes is because the statistical analysis processing performed by the second control unit 15 targets data obtained in 10 minutes in the present embodiment, and therefore, this time is always The time does not need to be 10 minutes, and may be set according to the condition of the data to be processed in the statistical analysis processing.

In step S106, since the storage of the continuous data for 10 minutes is completed, the dual port RAM 30
The address at which the observation data is to be written is moved to the first address of the area where the observation data is stored, and step S101 is performed.
And the above processing is repeated.

The continuous observation data is stored in the storage unit 14 as described above. However, as described above, in this embodiment, the sampling data sampling time interval is 2 seconds. The time required for one cycle of the repetition processing in S105 must always be within 2 seconds. Instead of controlling the entire installation environment observation device 1A with one CPU, a multiprocessor system is used,
That is why the CPU 27 is exclusively allocated for the processing of FIG.

Next, FIG. 5 will be described. FIG. 4 is a flowchart of a control program executed by the CPU 31 stored in the ROM 32 of the second control unit 15 in FIG. First, in step S111, in order to execute the processing in step S112 and thereafter every 10 minutes, the elapse of time is measured, and the process proceeds to step S112 every 10 minutes.

In step S112, the 10-minute observation data written by the first control unit 13 is read out from the dual port RAM 30 and temporarily stored in the RAM 33. In the next step S113, these observation data are statistically analyzed. . Details of this processing will be described later.

In step S114, data observed by the observation device 7 is obtained via the device interface unit 17. In the present embodiment, the observation items are the nitrogen oxide concentrations in the atmosphere (NO, NO ₂ , N
Ox) and sulfur dioxide concentration (SO ₂ ), as well as the precipitation and pH of precipitation over the last 10 minutes from acid rain gauge 35, and
The sunshine time during the last 10 minutes is acquired from the sunshine meter 36.

In step S115, the sub-environment observation device 4
The statistical observation data observed and subjected to the statistical analysis processing is acquired through the sub-environment observation device interface unit 18. For this purpose, first, data indicating a request to transfer statistical observation data is transmitted from the installation environment observation device 1A to the sub environment observation device 4. Since the sub-environment observation device 4 transfers the statistical observation data in response to the transfer request, the data is acquired. The observation items of the sub-environment observation device 4 in the present embodiment are only those relating to the wind environment (wind direction / wind speed), and those obtained by statistically analyzing these observation data are acquired. The sub-environment observation device 4 will be described later.

In step S116, the digital value output from the instrument operating state observing section 19 is acquired, and the continuous observing section 11 is obtained.
And the current consumption of each of the observation devices 7 is obtained. The current consumption can be easily calculated from the inserted resistance value and the potential difference between both ends of the resistance value according to Ohm's law.

In step S117, step S113
In step S118, the current time is stored in the transmission date and time area of the mail header of the created e-mail. Is transmitted to the installation environment monitoring device 2 via the server, and then returns to step S111. In the present embodiment, since the Internet is used as the communication network 3, a simple mail transfer protocol (SMT) is used as a communication protocol for electronic mail transmission.

Next, the statistical analysis processing of step S113 in FIG. 5 will be described. FIG. 6 shows a flowchart of the statistical analysis process. In the statistical analysis processing, the processing shown in FIG. 6A is performed for the temperature, humidity, and wind speed, and the processing shown in FIG. First, FIG.

FIG. 6A shows a process for obtaining an average value, a standard deviation, and a maximum (highest) value and a minimum (lowest) value in observation data for each observation item. First, steps S121 to S12
In step 3, the average value and standard deviation of the observation data are calculated. The number of observation data for each observation item is n, and each observation data is xi (i =
1, 2, 3,..., N), the average value of the observation data is obtained by the following equation (1), and the standard deviation is obtained by the following equation (2).

[0059]

(Equation 1)

In the present embodiment, the number n of observation data for 10 minutes is 10 [minutes] × 60 [seconds / minute] ［2 [seconds / data, since the sampling interval of each observation data is 2 seconds. ] = 300 [data]. Therefore, in order to obtain the average value and the standard deviation, the sum of the observation data and the sum of squares may be obtained later.

Therefore, in step S121, the RAM 3
3, the observation data is read out, the total sum and the sum of the squares are obtained, and from these values, the average value is calculated by equation (1) in step S122, and the standard deviation is calculated by equation (2) in step S123. .

In step S124, the maximum (highest) value and the minimum (lowest) value in the observation data are extracted for each observation item. As for the wind speed data, the minimum value is not so important as data, so only the maximum value is obtained.

Step S125 is a step for processing only when analyzing the wind speed data. The wind direction when the maximum wind speed extracted in step S124 is observed is extracted from the wind direction data.

In the present embodiment, the above-mentioned statistical analysis processing is performed for four observation items of wind speed 1, wind speed 2, temperature and humidity, and the maximum wind direction of wind speed 1 is from wind direction 1; The maximum wind direction is extracted from wind direction 2.

In step S131, wind direction observation data is read from the RAM 33, the number of data for each wind direction is counted, and a frequency distribution for the wind direction is obtained.

In step S132, step S131
From the frequency distribution obtained in the above, the most wind direction in the observation data is obtained. In step S133, the frequency of the most frequent wind direction obtained in step S132 is obtained from the frequency distribution obtained in step S131, and the frequency of the most frequent wind direction with respect to all frequencies is obtained as a percentage.

In the present embodiment, the above-described statistical analysis processing is performed for two observation items, wind direction 1 and wind direction 2. Next, the e-mail creation processing in step S117 in FIG. 5 will be described.

FIG. 7 shows a format of an electronic mail created by the electronic mail creating process. FIG. 1A shows an example of a general e-mail format, and an e-mail is roughly divided into a mail header and a mail body. The mail header stores the mail address of the mail sender, the mail address of the mail destination, the subject of the mail (also referred to as a subject, a title, and the like), the time of mail transmission, and the like.

FIG. 9B shows a format used in the present embodiment for storing each observation data in the body area of the electronic mail. All mail texts are created with text data, and data is separated by commas (,). In the same figure, the portions marked with “-” are basically no data, and commas are continued. At the end of each line, a line feed code is added instead of a comma.

FIG. 8 is a flowchart of the electronic mail creation process. In step S141, a number indicating the observation time of the observation data included in the e-mail created this time in units of 10 minutes is stored as the subject of the e-mail in the subject area of the mail header.

A method similar to that of the anemometer 22A is used in which the wind direction is represented by a gray code and output. Although the sub-environment observation device 4 in the present embodiment limits the observation target to the wind environment, it is a matter of course that observation can be performed by providing a thermometer or a hygrometer.

In the present embodiment, only the pulse counter 53 is used for the observation section interface section 42 and the third control section 43 because of the output system of the anemometer 51 and the anemometer 52.

Except for the difference in the number of items of observation data, the flowchart (FIG. 3) of the control program executed by the CPU 27 of the first control unit 13 of the installation environment observation apparatus 1A is almost the same. FIG.
0 will be described.

First, in step S151, data on the number of pulses output from the pulse counter 53 is obtained, and the number of pulses is converted into an observed wind speed.
Then, digital data that is a gray code output from the anemometer 52 is obtained and converted into a wind direction.

In step S153, step S151
And the observation data obtained in step S152 is stored in the storage unit 444.
In the dual port RAM 57. FIG. 11 shows a storage format of observation data in the dual port RAM 57. Each data is all 2-byte data,

It is sequentially stored in the repetition processing from 1 to step S153.

At step S154, the dual port R
The elapsed time since the observation data was stored at the top address of the area for storing the observation data of AM57 is checked.
If it has exceeded 0 minutes, the process proceeds to step S155, while
Otherwise, the process returns to step S151, and the processes from step S151 to step S153 are repeated. Note that the time of 10 minutes here is, as in the case of step S105 in FIG. 3, that the statistical analysis processing performed by the fourth control unit 45 in the present embodiment is based on data obtained in 10 minutes. To do that.

At step S155, the dual port R
The address at which the observation data is written to the AM 57 is moved to the first address of the area where the observation data is stored, and the process returns to step S151 to repeat the above-described processing.

Next, the flowchart of FIG. 12 will be described.
FIG. 17 is a flowchart of a control program executed by the CPU 58 stored in the ROM 59 of the fourth control unit 45 in FIG.

The processing from step S161 to step S163 is processing for transferring the statistical observation data to the installation environment observation apparatus 1A. First, in step S161, the installation environment observation device interface unit 46 is monitored. In step S162, if a data transfer request is received from the installation environment observation device 1A, the process proceeds to step S163.
The result data (statistical observation data) of the statistical analysis process stored in the RAM 60 in step S167 described later is transmitted from the installation environment observation device interface unit 46 to the installation environment observation device 1A.
And the process proceeds to step S164. On the other hand, step S
If it is determined in 162 that the case is not the case described above, the process directly proceeds to step S164.

Steps S164 to S167 are processes for statistically analyzing the data observed by the continuous observation unit 41 at intervals of 10 minutes and temporarily storing the data in the RAM 60. In step S165, the processing after step S166 is performed by 10
In order to execute the process every minute, the elapsed time is counted, and the process proceeds to step S166 every 10 minutes. On the other hand, if 10 minutes have not elapsed, the process returns to step S161, and the above-described processing is repeated.

In step S166, the 10-minute observation data written by the third control unit 43 is read out from the dual port RAM 57 and temporarily stored in the RAM 60. In the next step S166, these observation data are statistically analyzed. . Statistical analysis processing is installation environment observation device 1A
The processing shown in the flowchart of FIG. 6A is performed for the wind speed, and the processing shown in the flowchart of FIG. 6B is performed for the wind direction.

In step S167, step S166
The RAM 60 stores the average value, standard deviation, maximum value, wind direction when the wind speed is the maximum value, the maximum wind direction, and the frequency of the maximum wind direction as the results of the statistical analysis processing of the observation data by the RAM 60.
And temporarily returns to step S161. The stored data is read out in step S163 and transferred to the installation environment observation device 1A.

In the sub-environment observation device 4 according to the present embodiment described above, the equipment interface unit for connecting other observation equipment and acquiring observation data, and the continuous observation unit, which are provided in the installation environment observation device 1A, are provided. Alternatively, an instrument observation state observation unit for observing the operation state of another observation instrument is not provided, but it is of course possible to equip them.
When these are provided, the programs executed by the fourth control unit 45 and the second control unit 15 are changed, and the sub-environment observation device 4 changes the installation environment observation device 1A to the installation environment monitoring device 2A. Add processing to transfer observation data to.

Next, the installation environment monitoring device 2 will be described. As shown in FIG. 13, the installation environment monitoring device 2 includes a main control unit 71, an output unit 72, a storage unit 73, and a communication unit 74, and is mutually connected by a bus 75.

The main control unit 71 comprises a CPU 81, a RAM 8
2. It is composed of a ROM 83, and the CPU 81 controls the entire operation of the installation environment monitoring apparatus 2 by executing a control program stored in the ROM 83 while using the RAM 82 as a work area.

The output section 72 comprises a display device 84 such as a CRT display and an output control section 85.
In accordance with a display instruction from the PU 81, characters, graphics, and the like are displayed on the display device 84. It is also possible to provide a printer instead of the display device 84 so as to print out on paper.

The storage unit 73 is composed of a storage device 86 such as a hard disk device and a storage control unit 87, and is extracted from e-mail sent from each of the installation environment observation devices 1A, 1B, 1C,. Store observation data. Also, the observation data that has been shaped for the information terminal 5 is stored.

The communication section 74 is composed of a network interface section 88 and a communication control section 89, connects the installation environment monitoring device 2 to the communication network 3, and sends from each of the installation environment observation devices 1A, 1B, 1C,. Terminal 5 for receiving received e-mails and observing data after shaping
Send to.

The control program is stored in the R of the main controller 71.
Instead of storing the control program in the OM 83, the control program is stored in the storage device 86 of the storage unit 73, and when the installation environment monitoring device 2 is operated, the CPU 81 loads the control program into the RAM 82, and thereafter, RA
The CPU 81 may execute the control program of M82. In this way, the installation environment monitoring device 2 can use a computer having a standard configuration having a function connectable to the communication network 3.

Next, a flowchart of a control program executed by the CPU 81 of FIG. 14 will be described with reference to FIG. For simplicity of explanation, here, the installation environment monitoring device monitored by the installation environment monitoring device 2 is 1A.
However, when monitoring a plurality of installation environment observation devices, the processes of steps S176 to S179 in FIG. 14 are applied to the e-mail from each of the installation environment observation devices.

First, in step S171, the communication unit 74
To cause the communication unit 74 to receive communication data transmitted through the communication network 3. In step S172, the contents of the received communication data are checked. If the request is a transfer request of the observation data from the information terminal 5 to the installation environment monitoring device 2, the process proceeds to step S173, where the data is formatted by HTML which is performed in an e-mail reception process described later. The processed observation data is read out from the storage unit 73, and the observation data is read from the storage unit 73. The observation data is a hypertext transfer protocol (HTTP: HyperText) which is a communication protocol used for transmitting HTML document data.
Transfer Protocol) from the communication unit 74 to the information terminal 5 via the communication network 3, and
Return to 171. On the other hand, otherwise, step S1
Proceed to 74.

In step S174, the content of the received communication data is checked, and if the request is to transfer the observation data from the maintenance station 6 to the installation environment monitoring device 2,
Proceeding to step S175, the observation data before shaping received in the e-mail reception processing described later and stored in the storage unit 73 is transferred to a file transfer protocol (FTP: File) mainly used as a communication protocol for file transfer.
The transfer is performed from the communication unit 74 to the maintenance station 6 via the communication network 3 using Transfer Protocol), and the process returns to step S171. On the other hand, otherwise, the process proceeds to step S176.

In step S176, the contents of the received communication data are checked, and if it is an e-mail from installation environment monitoring device 1A to installation environment monitoring device 2, step S177
The process proceeds to step S17, where an e-mail receiving process is performed.
Return to 1. On the other hand, otherwise, step S178
Proceed to. The e-mail receiving process will be described later.

In step S178, the elapsed time since the last e-mail was received from the installation environment observation device 1A is checked. If it has exceeded the predetermined time, the flow advances to step S179.
A warning display indicating that there is no new e-mail from the installation environment observation device 1A is displayed on the display device 84 of the output unit 72, and thereafter, the process returns to step S171. On the other hand, in other cases, nothing is performed and step S171 is performed.
Return to Since the time interval at which the installation environment observation device 1A creates and sends an e-mail is almost constant (in the present embodiment, about 10 minutes), the time elapsed since the last time the e-mail arrived is the time interval. Is exceeded, it is estimated that a failure has occurred in the installation environment observation device 1A, which is unable to send a new e-mail. However, when the Internet is used as the communication network 3, the transmission time from when an e-mail is sent to when it is received varies greatly depending on the traffic on the network and the like. Thus, the difference in transmission time is grasped, and the time interval for sending the e-mail from the installation environment observation device 1A is set to a predetermined time to be determined based on the difference in transmission time. Although not provided in the installation environment monitoring device 2 in the present embodiment, if an audio output function is provided, a warning sound is issued together with a warning display, so that an operator of the device can be further provided. It is more effective because it can call attention.

Next, the e-mail receiving process in step S177 in FIG. 14 will be described. FIG. 15 shows a flowchart of the e-mail receiving process. First, step S18
In step 1, the observation data observed by the instrument operation state observation unit 19 in FIG. 2 is extracted from the text of the received e-mail. That is, the current consumption of each instrument is extracted from the observation data stored in the body area of the e-mail in the format shown in FIG. 7B.

In step S182, it is checked whether or not the current consumption value extracted in step S181 is included in the range of the current consumption in the normal operation for all the meters. It is determined that the operation is normal, and the process proceeds to step S184. On the other hand, if there is a meter indicating a current consumption that is not a normal value, the process proceeds to step S183, and a warning display indicating that an abnormality has occurred is displayed on the display device 84 of the output unit 72 for the meter indicating the abnormal current consumption. And then step S
Proceed to 184.

In step S184, all the observation data included in the e-mail is extracted, collected as one data file for each installation environment monitoring device, and stored in the storage device 86 of the storage unit 73. FIG. 16 shows a storage device 86.
Is a format of a storage data file for the installation environment observation device 1A to be stored in the storage environment. In the same figure, the subject of the mail indicating the observation time and the text storing the observation data are cut out from the e-mail sent from the installation environment observation device 1A, and both are stored alternately.
The observation data, which is the body of the e-mail, is stored as text data while maintaining the format shown in FIG. 7B. For example, if each data is converted into binary data and then stored, the size of the file to be stored can be reduced.

In step S185, step S184
Except for the data obtained by the instrument operating state observing section 19, which is information for instrument maintenance and management, only the observation data related to the installation environment of the object is HTM.
The image data is shaped using L and stored in the storage device 86 of the storage unit 73. This shaping process will be described.

FIG. 17 shows an example of a shaping process using HTML. In this example, the processing is for displaying the precipitation data observed by the acid rain gauge 35 in FIG. 2 as a list for each time. First, a table of changes in precipitation observed by the acid rain gauge 35 is created from the observation data, and a graphics interchange format (GIF: generally used for exchanging images in a communication network) as one of image file formats. (GraphicsInterchange Format) format. The file name of this image data shown in FIG.

FIG. 17B is a specific example of an HTML document for displaying table.gif on a web browser. In the same figure, <HTML>, <BR>, <IMG SRC = "table.gif">, </ HTML>
Are called tags. Briefly describing each tag, <HTML> ~ </
HTML> indicates that the text sandwiched between the two is an HTML document. <BR> is a tag indicating a line feed. Also,
<IMG SRC = "table.gif"> is an image file table in the text.
Indicates that a gif should be interrupted and displayed. Fig. (B)
Let the file name of the text file be display.html.

FIG. 14C shows table.gif and display.html.
5 shows a screen display by a web browser that has received the web page. Thereafter, when the observation data is updated, only table.gif needs to be updated.

As described above, by shaping the observation statistical data using HTML and transmitting the data, the information terminal 5 does not prepare special application software or the like for displaying the observation statistical data. Observation data can be displayed using a general web browser for utilizing. FIG. 17 shows an example in which a table is displayed. For example, a one-line graph showing changes in temperature observation data in a line graph may be created as a GIF format image file and displayed in the same manner as in FIG. Is also possible. If the web browser of the communication terminal 5 is compatible with HTML version 3.0 or later, tags for table setting are <TABLE>,
By using <TR>, <TD>, <TH>, etc., and describing the data of each cell of the table directly in the HTML document, the table can be displayed without using an image file.

Returning to the description of the flowchart of FIG. In step S186, the fact that a new e-mail including the observation data has arrived is displayed on the display device 84 of the output unit 72. The contents indicate the source of the email and the observation time (that is, the subject of the email).

In step S187, the time for checking the elapsed time from the arrival of the e-mail in step S178 in FIG. 14 is reset to zero, the processing is restarted, and the current e-mail reception processing ends.

Next, the information terminal 5 and the maintenance station 6 will be described. Both are installation environment monitoring devices 2
For the information terminal 5, only the stored and observed observation statistical data is transferred via the communication network 3, while for the maintenance station 6, system maintenance and management is performed. Is different in that all the observation data included in the e-mail from the installation environment observation device 1A, including the observation data by the instrument operation state observation unit 19 necessary for the operation, can be transferred. Only. Therefore, both hardware configurations may be the same.

The information terminal 5 and the maintenance station 6 are, as shown in FIG.
2, an output unit 93 and a communication unit 94.
5 are interconnected.

The input unit 91 comprises an input device 101 such as a mouse or a keyboard, and an input control unit 102, and accepts requests from operators of the information terminal 5 and the maintenance station 6.

The main control unit 92 includes a CPU 103, a RAM 1
04, the ROM 105 and the CPU 103
The overall operation is controlled by executing the control program stored in the storage unit 05 while using the RAM 104 as a work area.

The output section 93 comprises a display device 106 such as a liquid crystal display and an output control section 107.
In accordance with a display instruction from the CPU 103, characters, graphics, and the like are displayed on the display device 106.

The communication section 94 is composed of a network interface section 108 and a communication control section 109, connects the information terminal 5 and the maintenance station 6 to the communication network 3, and communicates each observation data by communicating with the installation environment monitoring device 2. Receive transfer.

As in the configuration of the installation environment monitoring device 2 shown in FIG. 13, a storage unit composed of a hard disk device or the like connected to the bus 95 is provided.
Instead of storing the control program in the ROM 105, the control program is stored in the storage device of the storage unit, and when the information terminal 5 and the maintenance station 6 are operated, the CPU 103 loads the control program into the RAM 104. Copy the control program of RAM 104 to C
The PU 103 may execute it. In this way, the information terminal 5 and the maintenance station 6 can use a computer having a standard configuration having a function connectable to the communication network 3.

Next, a control program executed by the CPU 103 will be described. In the case of the information terminal 5, as described above, the transmitted observation statistical data is shaped using HTML, so that software of a general web browser is prepared and executed by the CPU 103. When the operator performs an input requesting data transfer to the monitoring device 2 from the input unit 91, the observation statistical data is displayed on the display device 106 of the output unit 93.

The CP at the maintenance station 6
FIG. 19 shows a flowchart of the control program executed in U103. First, in step S191, an input operation performed by the operator on the input device 101 of the input unit 91 is acquired, and in step S192, if the input operation is a display request of observation data, the process proceeds to step S193. On the other hand, if other than that, step S191
Return to Here, if the maintenance station 6 has another function, the input information acquired before returning to step S191 may be passed to the function.

In step S193, a request to transfer observation data is transmitted from the communication section 94 to the installation environment monitoring device 2 via the communication network 3. In step S194, the observation data transferred from the installation environment monitoring device 2 is received by the communication unit 94, and then the observation data received in step S195 is displayed on the display device 106 of the output unit 93.

The operator of the maintenance station 6 looks at the observation data displayed on the display device 106 and monitors whether an abnormal value has occurred. If an abnormal value is found, the device is broken down. And repair the device. Examples of the determination of the abnormality of the observation data include, in addition to the abnormality of the data observed by the instrument operation state observation unit 19,
For example, the maximum value of the wind speed is continuously observed to be zero, or the temperature of the installation environment is observed at a high or low temperature value which is not normally possible at the installation place of the instrument. In addition, information such as a warning about delay of incoming e-mail in step S179 in FIG. 14 and a warning indicating an abnormality in observation data of the instrument operation state observation unit 19 in step S183 in FIG. 15 is obtained from the installation environment monitoring device 2. It is also convenient to display them.

It is convenient to divert a portable computer or the like to the maintenance station 6 so that operation confirmation after repair can be performed at the installation location of the apparatus. If the maintenance station 6 is provided with a web browser, it can be shared with the information terminal 5, which is convenient. Furthermore, if the information terminal 5 and the maintenance station 6 are shared, if the data obtained by the instrument operating state observing section 19 is subjected to the shaping processing of the observation data performed by the installation environment monitoring device 2, the maintenance and management of the system can be performed. Although there is a problem that the information about the information can be browsed by a person who does not need it, the program shown in the flowchart of FIG. 19 may be unnecessary.
