Description

[0001]
BACKGROUND OF THE INVENTION

[0002]
[Prior art]
In recent years, mobile phones have been widely used, and a system in which remote monitoring is performed using such mobile phones has started to be proposed. Such a system has a function of transmitting information to a specific mobile phone. As information to be adopted, one type of information is adopted alone.
[0003]
[Problems to be solved by the invention]
However, when information is transmitted to only one specific mobile phone, there is an inconvenience that information cannot actually be transmitted when the mobile phone cannot be operated for some reason.
[0004]
In order to eliminate such inconvenience, it is conceivable to transmit information to a plurality of mobile phones. However, when information is simultaneously transmitted to a plurality of individuals, the information transmission range can be widened, but there is an inconvenience that the impact on each individual is weakened.
[0005]
Specifically, for example, when transmitting information indicating that some countermeasure is required, if the information transmission range is widened, information transmission omission can be greatly reduced. On the other hand, each individual knows that it may not be the only person who receives the information, so even if someone receives the information, somebody needs to There is an inconvenience that the necessary countermeasures are not performed quickly, and in the worst case, the necessary countermeasures are not performed at all even though the information is transmitted.
[0006]
In addition, since one type of information is adopted alone, if the information is affected by noise or the like, the wrong information will be transmitted, and the information is incorrect. There is a disadvantage that it cannot be determined whether or not there is.
[0007]
The present invention has been made in view of the above problems, and provides a remote monitoring method and apparatus capable of widening the parameter transmission range of the monitoring target equipment and increasing the impact of parameter transmission.

DETAILED DESCRIPTION OF THE INVENTION
Embodiments of a remote monitoring method and apparatus according to the present invention will be described below in detail with reference to the accompanying drawings.
[0056]
FIG. 1 is a schematic view showing an embodiment of a remote monitoring system to which the remote monitoring method of the present invention is applied.
[0057]
This remote monitoring system measures a parameter of a facility to be monitored and transmits a measurement parameter, a parameter measurement transmission device 1, a server 2 that receives the transmitted parameter, and a plurality of devices that receive mail sent from the server 2. Mobile phone 3.
[0058]
The parameter measurement transmission device 1 measures a preset parameter of the monitoring target equipment, determines the presence / absence of an abnormality based on the measurement parameter, transmits the parameter measurement result at predetermined time intervals, and determines that an abnormality has occurred. In response to this, the necessary data is sent immediately.
[0059]
The server 2 includes data for specifying the mobile phone 3 that is a target of the remote monitoring method of the present invention, processing software to be downloaded to the mobile phone 3, remote monitoring software for executing the remote monitoring method of the present invention, and the like. In addition, it has a memory device 2 ′ for storing data.
[0060]
The mobile phone 3 performs processing based on processing software downloaded from the server 2 to perform visual display on the display screen, and performs request processing to the server 2 as necessary.
[0061]
FIG. 2 is a diagram schematically showing the operation of the remote monitoring system of FIG.
[0062]
When the server 2 receives necessary data from the parameter measurement transmission device 1 in response to the determination that an abnormality has occurred, the server 2 selectively sends a mail to each of the plurality of mobile phones 3 in a predetermined order. To transmit.
[0063]
When the mobile phone 3 receives an e-mail from the server 2, the mobile phone 3 activates the software downloaded from the server 2 and performs a request process for the server 2 as necessary.
[0064]
When request processing is performed, the server 2 performs authentication processing of the mobile phone 3, performs reception confirmation of the request, and performs data distribution processing.
[0065]
In response to this data distribution process, the mobile phone 3 performs screen display based on the distribution data.
[0066]
Then, it demonstrates in detail based on a specific example.
[0067]
FIG. 3 is a diagram showing measurement locations in three water channels, where the measurement location in the first water channel is at points A and B, and the measurement location in the second water channel is at points C, D, and E. The measurement location in the third water channel is set at point F, respectively. The final exit where the three waterways merge is also set as the measurement location.
[0068]
Also, the measurement parameters at point A are PH values and oil, the measurement parameters at points B, C, and F are PH values, oil, harmful substances, and turbidity, and the measurement parameters at points D and E are PH. In the value, the measurement parameter at the final outlet is set to PH value, oil, and TOC (TotAl OrgAniC CARBon).
[0069]
FIG. 4 is a schematic diagram showing the main part of the parameter measurement sending device at point A.
[0070]
This parameter measurement and delivery device sucks water from the water channel by the submersible pump P, guides it to the sample tank, returns it to the water channel, and measures the PH value and oil film in the sample tank. Here, the PH value is measured by measuring the potential difference between the internal liquid in the glass electrode and the sample water and calculating the PH (for example, PH200 EFPkCl replenishment type PH200 intelligent two-wire PH transmitter / manufactured by Yokogawa Electric). The oil film is measured using an oil film meter (for example, oil film detector OF-10 type / manufactured by Electrochemical Instruments Co., Ltd.) that measures the reflectance away from the water surface. Further, the pumping amount of the submersible pump P is set to 80 L / min (40 to 60 L / min after the valve control), the capacity of the sample tank is set to 50 L, for example, and the residence time in the sample tank is set to about 1 min, for example. Is done. Here and below, the residence time is a time obtained by dividing the capacity of the liquid tank by the liquid inflow per unit time.
[0071]
FIG. 5 is a schematic diagram showing the main part of the parameter measurement and transmission apparatus at points B, C and F.
[0072]
In addition to the configuration for measuring the PH value and the oil film as in FIG. 4, this parameter measurement and delivery device guides part of the water sucked from the water channel by the submersible pump P to the turbidity sample tank. After measuring the turbidity with a turbidimeter, it is returned to the water channel again, and another part of the water sucked from the water channel is guided to the hazardous substance meter by the submersible pump P and then returned to the water channel again. Yes. Here, the turbidity is measured using a turbidimeter (for example, a TB400G surface scattering turbidimeter / manufactured by Yokogawa Electric Co., Ltd.) that measures scattered light by applying light to the water surface and removing transmitted / reflected light. For the harmful substances, the potential (action potential) generated in the water during the activity of the fish is detected by the sensor installed in the aquarium, and the “activity amount” is calculated as a certain average value. This activity amount exceeds the upper and lower limits. Sometimes it is measured using a hazardous substance meter (for example, a continuous water quality monitoring device using a fish, Unirelief L4 / Unitika) that determines that an abnormality has occurred in the fish. In addition, the amount of water supplied to the turbidity sample tank is set to, for example, 10 L / min, the capacity of the turbidity sample tank is set to, for example, 10 L, the residence time of the turbidity sample tank is set to, for example, about 1 min, Is set to 20 L, for example, and the residence time of the hazardous substance meter is set to about 4 min.
[0073]
FIG. 6 is a schematic diagram showing the main part of the parameter measurement and transmission apparatus at point D and point E.
[0074]
This parameter measurement sending device is configured by installing a PH meter directly in the water channel.
[0075]
FIG. 7 is a schematic view showing the main part of the parameter measurement sending device at the final exit.
[0076]
This parameter measurement and delivery device is provided with a sample tank (oil film meter sample tank) and an oil film meter similar to those in FIG. 4, and also guides a part of the water sucked from the water channel by the submersible pump P to the common sample tank, A part of the water from the common sample tank is led to the PH sample tank provided with the PH meter, and the other part is led to the TOC meter, and then returned to the water channel again. Here, the TOC is a TOC meter that converts inorganic carbon to carbon dioxide by burning the organic carbon in the presence of a high-temperature catalyst after removing the inorganic carbon, and detects this with an infrared analyzer (for example, TOC Automatic It is measured using an analyzer TOC-610 / manufactured by Toray Engineering. Also, the amount of water supplied to the common sample tank and PH sample tank is set to, for example, 10 L / min, the amount of water supplied to the TOC meter is set to, for example, 0.2 L / 15 min, and the capacity of the common sample tank and PH sample tank is set to, for example, The residence time of the common sample tank and the PH sample tank is set to about 1 min, and the measurement frequency of the TOC meter is set to 1 time / 15 min.
[0077]
As can be seen from the above, with respect to the PH meter, oil film meter, and turbidity meter, the sample tank is replaced in about one minute. Then, by setting the parameter measurement data update cycle every minute, it is possible to easily distinguish between the false alarm and the abnormality.
[0078]
FIG. 8 is a schematic diagram illustrating an example of an abnormality notification when an abnormality occurs. In addition, abnormality is detected by parameter measurement data and a predetermined comparison result, for example. FIG. 8 shows a case where abnormality notification is performed on the mobile phone for the person in charge 1 and the mobile phone for the person in charge 2.
[0079]
When an abnormality occurs, the person in charge 1 is notified of abnormality (alarm notice) three times with the interval set to 1 minute, and then the person in charge 2 is made into an interval of 1 minute. The abnormality notification is performed only three times after setting, and then the above operation is repeated. Then, when it is confirmed that the alarm notification has been seen, the abnormality notification is interrupted.
[0080]
Therefore, the person in charge can be notified of the abnormality notice quickly, and the inconvenience of overlooking the abnormality can be prevented. Also, if you send an abnormality notification email to all the persons in charge at the same time, it will become unclear who should respond, and there will be inconvenience that the response will be delayed because someone will be responding. By making it like 8, the responsibility can be clarified and the delay of the response can be prevented.
[0081]
However, if the person in charge 1 responds while the abnormality notice mail is being sent to the person in charge 2, it is preferable that the abnormality notice mail is not sent to any person in charge thereafter. In addition, when one of the persons in charge responds, when the other person in charge notices the abnormality notification mail and logs in (or browses) to cope with it, it can be seen that the corresponding inspection has already been performed. The contents may be changed as follows. Of course, an email indicating that a response has already been made may be sent to the other person in charge.
[0082]
FIG. 9 is a process flow diagram for explaining a process in the case where an abnormality occurs in a state where the data update cycle is set to one minute and an abnormality in PH and turbidity occurs during the holiday night. Since the abnormality alarm is transmitted from the measuring instrument, an abnormality mail is notified regardless of the system data update cycle.
[0083]
In step SP1, an abnormal mail is received. In step SP2, the monitoring software is activated. In step SP3, the content of the alarm is confirmed. In step SP4, the trend of the alarm occurrence location is confirmed.
[0084]
Then, when the trend is as shown in FIG. 10A, it can be seen that although it has instantaneously become an abnormal value, it has immediately returned to the normal value. Observe. As a result, if there is no change (step SP6), equipment inspection is performed at a later date (step SP7). On the contrary, when the alarm occurs frequently (step SP8), the crisis is inspected and cleaned (step SP9).
[0085]
On the other hand, when the trend is as shown in FIG. 10B, it can be seen that abnormal drainage has flowed, so in step SP10, rush to the site, and in step SP11, deal with treatment (for example, abnormal occurrence) Investigation of location, prevention and treatment of abnormal drainage).
[0086]
Therefore, even if an abnormal mail is received, the subsequent measures can be varied by referring to the trend data.
[0087]
FIG. 11 is a process flow diagram illustrating a process in the case where an abnormality occurs in a state where the data update cycle is set to one minute and an oil abnormality occurs on a holiday night.
[0088]
In step SP1, an abnormal mail is received. In step SP2, the monitoring software is activated. In step SP3, the content of the alarm is confirmed. In step SP4, the trend of the alarm occurrence location is confirmed.
[0089]
Then, when the trend is as shown in FIGS. 12A and 12B, since it becomes an abnormal value instantaneously, it can be seen that it has returned to the normal value immediately. Observe the situation. As a result, if there is no change (step SP6), when the trend is as shown in FIG. 12A, equipment inspection is performed at a later date (step SP7), and the trend is as shown in FIG. In some cases (when the measured value is disturbed due to a change in the liquid level due to a change in the pumping amount of the submersible pump), an equipment inspection is performed the next day (step SP8). On the contrary, when the alarm occurs frequently (step SP9), the crisis is inspected and cleaned (step SP10).
[0090]
Conversely, if the trend is as shown in FIG. 12C, it can be seen that abnormal drainage has flowed, so in step SP11, the site is rushed to the site, and in step SP12, treatment is handled (for example, occurrence of an abnormality). Investigation of location, prevention and treatment of abnormal drainage).
[0091]
Therefore, even if an abnormal mail is received, the subsequent measures can be varied by referring to the trend data.
[0092]
FIG. 13 is a process flow diagram illustrating a process when a TOC abnormality occurs on a holiday night. Note that the TOC meter performs measurement at a frequency of once / 15 min, and there is no lower limit value in the alarm, and an alarm is generated only when the upper limit value is exceeded twice in succession.
[0093]
In step SP1, an abnormal mail is received. In step SP2, the monitoring software is activated. In step SP3, the content of the alarm is confirmed. In step SP4, the trend of the alarm occurrence location is confirmed.
[0094]
And when the trend is as shown in FIG. 14 (A), since the abnormal value has returned to normal in two measurements, it can be determined that the device is abnormal or abnormal due to dirt such as dust, In step SP5, the state is observed without going out. As a result, if there is no change (step SP6), equipment inspection is performed at a later date (step SP7). Conversely, if an alarm occurs frequently (step SP8), the equipment is inspected and cleaned (step SP9).
[0095]
Conversely, if the trend is as shown in FIG. 14B, it can be seen that the abnormal drainage has flowed, so in step SP10, rush to the site, and in step SP11, deal with the treatment (for example, abnormal occurrence) Investigation of location, prevention and treatment of abnormal drainage).
[0096]
Therefore, even if an abnormal mail is received, the subsequent measures can be varied by referring to the trend data.
[0097]
If a hazardous substance abnormality occurs on a holiday night, the hazardous substance meter has almost no false alarms due to equipment abnormality. Because the harmful substance meter measures the action potential of fish, the average value for 1 minute becomes “activity amount”, and the upper and lower limits of the activity amount are set. Because.
[0098]
FIG. 15 is a process flow diagram illustrating a process when a trend two-point comparison process is performed. These two points are upstream and downstream of the same water channel, and the required time for drainage between the two points is known.
[0099]
In step SP1, an abnormal mail is received, and the trend is confirmed in step SP2.
[0100]
Then, as shown in FIG. 16A, when one trend shows an abnormality and the other trend does not show an abnormality, it can be determined that the device is abnormal. Check. Conversely, as shown in FIG. 16B, when both trends indicate an abnormality, it can be determined that the drainage is abnormal, and therefore, in step SP4, a countermeasure corresponding to the prevention of abnormal drainage is performed.
[0101]
FIG. 17 is a process flow diagram for explaining a specific example of a process for comparing trends on the same series.
[0102]
In step SP1, an abnormal mail is received, in step SP2, the monitoring software is activated, and in step SP3, the content of the alarm (PH abnormality has occurred at point C) is confirmed. In step SP4, C Check the trend of PH value at points D and D.
[0103]
When the trend is as shown in FIG. 18A, since the abnormality of the PH value recognized at the point C does not appear at the point D, it can be determined that the device is abnormal. In step SP5, Observe the situation without going out. As a result, if there is no change (step SP6), equipment inspection is performed at a later date (step SP7). Conversely, if an alarm occurs frequently (step SP8), the equipment is inspected and cleaned (step SP9).
[0104]
Conversely, when the trend is as shown in FIG. 18B, it can be seen that an abnormality in PH value is observed at points C and D, and that an abnormality in PH value has actually occurred. In step SP10, the vehicle is rushed to the site, and in step SP11, measures are taken (for example, investigation of an abnormality occurrence location, prevention of abnormal drainage outflow and processing).
[0105]
FIG. 19 is a process flow diagram illustrating a process when an abnormality occurs at two measurement points.
[0106]
In step SP1, an abnormal mail is received. In step SP2, the monitoring software is started. In step SP3, it is confirmed that a PH abnormality has occurred at point C. In step SP4, points C and D are detected. Check the trend of PH value.
[0107]
When the trend is as shown in FIG. 20 (A), since the large abnormality in the PH value recognized at the point C is considerably small at the point D, the amount of abnormal drainage that flows is small. Since it is considered that the wastewater treatment plant will further dilute, it will not take time to treat the abnormal wastewater. Therefore, in step SP5, investigation of the source of abnormal wastewater and confirmation of the downstream state in the trend I do.
[0108]
On the contrary, when the trend is as shown in FIG. 20 (B), an abnormally large PH value is recognized at the C point and the D point. Therefore, in step SP6, rush to the site. In step SP7, abnormal drainage treatment and abnormal drainage prevention are performed. In step SP8, the source of abnormal drainage is investigated, and downstream in the trend. Check the status.
[0109]
As can be seen from the above, when an abnormality occurs at both point C and point D, the degree of occurrence of abnormal drainage can be estimated by comparing the degree of influence at point C and the degree of influence at point D. . That is, for example, if the trend peak is large at point C and the trend peak is small at point D, it can be considered that the amount of abnormal drainage is small considering the distance of the water channel.
[0110]
Further, when the trend is as shown in FIG. 21A, the trend data at the point D has no significant PH value, but the trend data at the point C has no PH. Since no value abnormality is observed, it is considered that the site of abnormal drainage is between point C and point D.
[0111]
On the other hand, when the trend is as shown in FIG. 21B, a large PH value abnormality is observed in the trend data at point D, while a small PH value is present in the trend data at point C. Since abnormalities are observed, it is probable that the site where abnormal wastewater occurred was slightly upstream from point C, and part of the abnormal wastewater flowed into point C.
[0112]
By considering the trend data at two points in the same channel as described above, the range that can be the site of abnormal drainage can be easily narrowed down, greatly reducing the labor required to investigate the source of abnormal drainage can do.
[0113]
FIG. 22 is a process flow diagram for explaining how to deal with an abnormality in the PH value at point C.
[0114]
In step SP1, an abnormal mail is received. In step SP2, the monitoring software is started. In step SP3, it is confirmed that a PH abnormality has occurred at point C. In step SP4, points C and D are detected. Check the trend of PH value.
[0115]
Then, it is confirmed that the trend is as shown in step SP5, and in step SP6, the abnormal drainage source is investigated and the downstream state in the trend is confirmed.
[0116]
Thereafter, it is confirmed that the trend is as shown in step SP7, and in step SP8, the vehicle is rushed to the site, and in step SP9, abnormal drainage treatment and abnormal drainage outflow prevention are performed.
[0117]
As can be seen from the above, when a PH value abnormality occurs at point C, the abnormality can be processed while monitoring the trend data at point D, and the outflow of polluted water to the river can be prevented. . As a result, even when the number of workers for handling is small, it is possible to respond quickly.
[0118]
FIG. 23 is a process flow diagram illustrating a process that uses trend data of points in another water channel.
[0119]
In step SP1, a report is received that an abnormal drainage has flowed out in the building, and in step SP2, the site is rushed to the site. In step SP3, the monitoring software is started. Check the trend data.
[0120]
When the trend data is as shown in step SP5, an abnormality in the PH value is recognized only at point A. Therefore, in step SP6, the inflow route to point A is investigated and downstream of point A. Measures for abnormal wastewater and prevent outflow of abnormal wastewater.
[0121]
If the trend data is as shown in step SP7, an abnormality in the PH value is recognized only at point C. Therefore, in step SP8, the inflow route to point C is investigated and downstream of point C. Measures for abnormal wastewater and prevent outflow of abnormal wastewater.
[0122]
Further, when the trend data is as shown in step SP9, an abnormality in the PH value is recognized at both the points A and C. Therefore, in step SP10, the inflow route to the points A and C Investigation of abnormal drainage downstream of point A and point C and prevention of abnormal drainage outflow.
[0123]
As a result, when an abnormality occurs in the building between the 1st and 2nd canals and it is unclear how the surrounding canals are running, take measures while monitoring both points A and C. By doing this, it is possible to quickly check which water channel the abnormal drainage flows out.
[0124]
Moreover, it is also possible to narrow down the locations where an abnormality has occurred as described above, and then further identify the location and cause by utilizing the above-mentioned comparison in the same series.
[0125]
FIG. 24 is a diagram showing an example of screen display in a mobile phone.
[0126]
24A shows an alarm screen that displays the type and date of alarm, FIG. 24B shows a trend screen that displays trend data, and FIG. 24C shows parameter measurement values as analog values. Each analog value display screen is shown.
[0127]
These display screens can be switched by operating the mobile phone.
[0128]
Further, since the trend screen shows changes in parameter measurement values over a certain period, it is preferable to display changes in parameter measurement values over as long a period as possible. Therefore, it is preferable to match one dot in the time axis direction on the trend screen with the time interval of the intermittent measurement, and as many parameter measurement values as possible can be displayed.
