Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention divides a basin composed of rivers, lakes, marshes, waterways, reservoirs, etc. into a plurality of regions, and disperses and arranges a plurality of analyzers for analyzing flow behavior of each basin. More particularly, the present invention relates to a water operation monitoring system that communicates analysis calculation results between analysis devices and executes an analysis in consideration of flow behavior in another area.

[0002]

2. Description of the Related Art In the operation of water between a plurality of flow passage systems and regions, such as a drainage network and a water guide, by controlling the respective flow passage systems and regions in cooperation, the total energy supplied to the plant can be reduced. This can be expected to reduce and improve the reliability against equipment failure. In order to realize such efficient water operation, it is important to understand the flow behavior of the monitoring target area. Considering the behavior of other areas that exchange water, the water level and flow rate of , Water quality, etc. need to be analyzed.

As a method of managing a water operation system including a plurality of areas, for example, Japanese Patent Application Laid-Open No. 6-88373 discloses a sewage treatment system in which a plurality of treatment areas are integrated and the facilities are operated in a wide area. A facility group management system is introduced. Further, Japanese Patent Laid-Open No. Hei 6-332503 proposes an operation control device for integrally processing a plurality of pump plants.

[0004]

SUMMARY OF THE INVENTION The above-mentioned Japanese Patent Laid-Open No. 6-883 is disclosed.
No. 73 does not consider water operation between treatment areas. That is, the treatment area is set so that the water operation is performed in one treatment area. Therefore, when it becomes necessary to perform water operation over a plurality of treatment areas, it is necessary to newly set and manage all the treatment areas targeted for water operation as one new treatment area.

[0005] In Japanese Patent Application Laid-Open No. 6-332503, monitoring is performed on a newly set large area. For that purpose, a large-sized and expensive analyzer with sufficient computing power to cover a large area is required. In addition, the analyzers used for monitoring water operation in small areas up to now cannot be used together, and this is wasted.

Further, for example, even when analyzing the same kind of flow phenomenon such as a plurality of rivers, the flow velocity, the water depth, the water level, the distance of the basin, etc. are different for each river, and therefore, there is an optimum analysis period for each. When considering the behavior of other areas for exchanging water, it is necessary to perform analysis in accordance with the river at the analysis period, and an analyzer having a large processing capacity is required.

[0007] Further, in one area, a portion such as a lake or a marsh or a reservoir where the change rate of the flow behavior is relatively small, a river,
If there is a mixture of high speed changes such as waterways,
Since it is necessary to perform analysis in a short analysis cycle in accordance with a portion where the change speed is high, an analyzer having a larger processing capacity is required.

As a means for solving this problem, small analyzers for monitoring water operation in each of the small areas are distributed and arranged without newly setting a large area.
Regarding water operation between areas, there is a distributed water operation monitoring system that considers the effects while exchanging analysis results between analysis devices.

[0009] However, in the conventional distributed water operation monitoring system, an analysis device targeting a lake, a reservoir, or the like having a small change rate of flow behavior as a target area, and a river, a waterway, etc. having a large change rate as a target area. In general, the analysis progress time at the same time in the analysis device differs from that of the analysis device. Therefore, when exchanging the analysis result between the analysis devices, for example, the analysis progress time of another analysis device is earlier than the analysis result, and the analysis result of the required analysis progress time has already disappeared from the storage device. And so on. Of course, it is sufficient to store all the past analysis results, but for that, a huge storage device is required, which is difficult to realize. In addition, such a configuration negates the advantage of the distributed water operation monitoring system in which a small analyzer is used in combination.

An object of the present invention is to provide a water supply system capable of exchanging analysis results between a plurality of analyzers in accordance with a required analysis progress time without using a large storage device while utilizing the features of a distributed water operation monitoring system. To provide an operation monitoring system.

[0011]

SUMMARY OF THE INVENTION In order to achieve the above object, the present invention divides a basin composed of rivers, lakes, marshes, waterways, reservoirs, etc. into a plurality of regions and analyzes the flow behavior of each region. In a water operation monitoring system in which a plurality of analysis devices are distributed, an analysis calculation unit that analyzes the flow behavior while advancing the step of the analysis progress time based on the input data, and an analysis unit in the analysis calculation unit An analysis time management unit that manages the progress time, a transmission unit that sends out the analysis result of the analysis operation unit to another analysis device in response to a command from the analysis time management unit, and temporarily stores data transmitted from the other analysis device. An input buffer section for temporarily storing data, and a data input time management section for managing the time at which data is input to the analysis operation section. The analysis unit calculates the next time to input data to the analysis operation unit, and sends the analysis result of the analysis progress time corresponding to the time to the analysis time management unit of another analysis device to the input buffer unit. We propose a water operation monitoring system that is a means for making a reservation and inputting the data stored in the input buffer unit to the analysis operation unit in accordance with the next data input time of the analysis operation unit.

The analysis time management section manages the analysis progress time in the analysis operation section and transmits the analysis result at the analysis progress time included in the request for sending out the analysis result from the data input time management section of another analysis apparatus. Means for sending out to the input buffer unit of another analyzer requested through the unit.

At least one of the analysis calculation units of each analysis device is means for predicting and analyzing the future flow behavior of the region to be analyzed prior to the actual time based on the input data.

[0014] The analysis apparatus may include means for setting a data input time interval in accordance with a change speed of the flow behavior of the analysis target area, and / or the analysis progress time of the prediction analysis executed by the analysis calculation unit may be an actual time. Means may be provided for setting the degree preceding the time according to the change speed of the flow behavior of the region to be analyzed.

In the water operation monitoring system of the present invention, the analysis time management section of another analysis apparatus is reserved so that the analysis result of the analysis progress time corresponding to the next data input time of the analysis operation section is transmitted. Therefore, analysis data at a required analysis progress time can be reliably obtained from analysis devices having different analysis progress times. In addition, if the analysis device receiving the request sends out the data each time the analysis result at the time of receiving the reservation is obtained, there is no need to store the data thereafter, and the analysis result with another analysis device can be obtained. It is useless to have a large storage device for communication.

[0016]

BEST MODE FOR CARRYING OUT THE INVENTION

<< Embodiment 1 >> Next, Embodiment 1 of the water operation monitoring system according to the present invention will be described with reference to FIGS.

FIG. 1 is a block diagram showing an example of the configuration of an analyzer installed in the water operation monitoring system according to the present invention. The analysis device 1 includes an input unit 2 for inputting data necessary for analyzing flow behavior such as flow velocity, flow rate, water temperature, and water quality in a monitoring target area, and a flow behavior while advancing an analysis progress time step based on the input data. , An analysis time management unit 4 that manages the analysis progress time in the analysis operation unit 3, and a transmission unit 5 that sends an analysis result to another analysis device according to a command from the analysis time management unit 4. And an input buffer unit 6 for temporarily storing data transmitted from another analysis device, and a data input time management unit 7 for managing a time at which data is input to the analysis operation unit 3.

The operation of each section of the analyzer 1 configured as described above will be described. The data input time management unit 7 calculates a time at which the next data is input to the analysis operation unit 3. A reservation is made so that an analysis result at an analysis progress time corresponding to the next data input time is sent to another analysis device that is analyzing flow behavior in another area of water operation in cooperation with this analysis device. . When an analysis result at an analysis progress time corresponding to the reserved next data input time is sent from another analysis device, the input buffer unit 6 temporarily stores the analysis result. When the next data input time comes, the data input management unit 7 transfers the analysis result sent from another analysis device stored in the input buffer unit 6 to the input unit 2. The analysis operation unit 3 takes in the analysis result sent from the other analysis device via the input unit 2 together with the data from the sensor in its own area, and proceeds with the analysis based on the new data. Go.

The above operation is a case where the request for sending out the analysis result is sent to another analyzing device. Conversely, the operation when the sending out of the analysis result is requested from another analyzing device will be described below. I do. The reservation of the request for sending out the analysis result from another analysis device enters the analysis time management unit 4. The analysis time management unit 4 continuously monitors the analysis progress time of the analysis calculation unit 3, and when the analysis progress time matches the analysis progress time corresponding to the next data input time requested by another analysis device, The analysis result at the analysis progress time is analyzed by the analysis operation unit 3
To the transmission unit 5 and send it out to another analyzer.

FIG. 2 is a block diagram showing an example of the configuration of a water operation monitoring system according to the present invention when a basin to be monitored is divided into two regions. That is, an analysis device a for analyzing a river a as one region a for two rivers having different flow behavior change rates.
It is a block diagram which shows an example of a structure of the water operation monitoring system which consists of the analyzer b which analyzes the river b as another area | region b.

The area a and the area b are connected to the waterway 8 and the waterway 9
Are connected to each other, and are operated by exchanging water with each other. A plurality of sensors 10 are installed in each of the area a and the area b, and a water treatment facility 11 such as a water purification plant may be provided. The data input time management unit a7 of the analysis device a reserves the sending of the analysis result from the analysis device b to the analysis time management unit b4, and conversely, the data input time management unit b7 of the analysis device b The sending of the analysis result from a is reserved for the analysis time management unit a4.

FIG. 3 is a diagram for explaining the progress of the analysis calculation in the two analyzers a and b and the state of data exchange between the two analyzers a and b. In FIG. 3, the horizontal axis represents the actual time, and the vertical axis represents the analysis progress time progressing in the analysis calculation units a3, b3 of the analyzers a, b.

The progress of the analysis calculation will be described with reference to the graph of the analyzer a shown in the upper part of FIG. The dashed line 101 is
This shows a case where the actual time is equal to the analysis progress time. Above the dashed line 101 indicates the case where the analysis progress time is ahead of the actual time, that is, the case where the prediction analysis is being performed. Conversely, below the dashed line 101, the analysis progress time is the actual time. The case where it is later is shown. The normal use of the water operation monitoring system is to predict a future flow behavior based on data at a certain point in time and to use the prediction result for water operation, so that the analysis proceeds above the dashed line 101.

In general, the flow prediction analysis is to execute a prediction calculation of a state after a predetermined time dT at a period τ with a flow state at a certain time as an initial value. The analysis time dT and the analysis period τ have optimal values depending on the state of the basin. In other words, in order to capture the flow phenomenon change, it is necessary to set the analysis period τ according to the change speed of the flow phenomenon, and from the measurement point to the prediction point, for example, the propagation time of the phenomenon from the water source to the water treatment plant Accordingly, it is necessary to determine the analysis time dT.

For example, in a river or a lake with a wide river, the change in the phenomenon is relatively gentle. Therefore, the analysis cycle τ may be set to be long. Since it becomes intense, it is necessary to set the analysis period τ to be short. The analysis time dT is set to a value corresponding to the distance from the measurement point to the prediction point and the flow velocity.

In the case of analysis, a boundary condition is required for each analysis period τ. In the predictive analysis based on the cooperation of a plurality of analyzers, a value of a boundary with a region handled by another analyzer is also set as a boundary condition.

The time 11 indicated by a white circle on the dashed line 101
Numerals 0, 111, and 112 indicate the points in time when the arithmetic analysis unit a3 of the analysis device a fetches data from the input unit a2, and the data is fetched at an analysis cycle τa interval. For example, time point 1
At 10, the data at the time T0 is taken into the input unit a2 from a sensor or the like, and at the same time, the analysis data at the analysis progress time T0 of the analysis device b is taken. The operation analysis unit a3 of the analysis device a advances the analysis based on the input data along the solid line 120 and prior to the actual time.
Similarly, data is newly input from the input unit a2 at time points 111 and 112, and the analysis proceeds along the solid lines 121 and 122. Therefore, solid lines 120, 121, 122
When the time points 130, 131, and 132 indicated by black circles are connected, the analysis time dTa precedes the actual time,
Predictive analysis will be performed.

The analysis operation of the analyzer b shown in the lower part of FIG. 3 proceeds in the same manner as the analyzer a. However, since the change speed of the flow behavior in the region b, which is the target of the analysis device b, is smaller than that in the region a, the analysis period τ represented by the time points 210 and 211 at which data is taken in from the input unit b2.
b is larger than the analyzer a. Also,
The magnitude of the slope of the solid lines 220 and 221 indicating the progress of the analysis,
That is, the degree of precedence of the analysis progress time with respect to the actual time is also different.

At the time point 111 when the actual time is T1, the analysis operation part a3, which has taken in the data from the input part a2, advances the prediction analysis along the solid line 121 before the actual time. At this time, the data input time management unit a7 determines the next data
The analysis result at the analysis progress time T2 corresponding to the time T2 is reserved. The analysis by the analysis device b is proceeding along the solid line 220, and has not yet reached the reserved analysis progress time T2 at the actual time T1. When the analysis of the analysis device b proceeds and the analysis progress time reaches T2, that is, the time point 230,
The analysis time management unit b4 of the analysis device b sends the analysis result at the analysis progress time T2 to the analysis device a via the transmission unit b5, as indicated by the arrow 141. The analysis result at the analysis progress time T2 of the analysis device b stored in the input buffer unit a6 indicates that when the actual time reaches the analysis progress time T2 which is the next data input time, that is, the time point 112,
The data is transferred to the input unit a2, input to the analysis calculation unit a3, and a new prediction analysis proceeds along the solid line 122. Thereafter, a similar operation is performed between the analyzers a and b.

FIG. 4 is a flowchart showing a procedure for exchanging data between two analyzers. Step 300: In the analysis device a that has finished capturing the input data at the actual time T1, the data input time management unit a7 sets the analysis progress time T2 in the analysis device b for the analysis progress time T2 when the next data is input. A reservation is made with respect to the analysis device b so as to send out the analysis result. Step 301: The analysis time management unit b4 of the analysis device b
The analysis progress time of the analysis calculation unit b3 is monitored. Step 302: The analysis time management unit b4 of the analysis device b
It is determined whether or not the reserved analysis progress time has reached T2. Step 303: When the reserved analysis progress time reaches T2, the transmission unit b5 of the analysis device b sends out the analysis result of the analysis operation unit b3 to the input buffer unit a6 of the analysis device a. Step 304: The input buffer unit a6 of the analyzer a
The analysis result of the analysis operation unit b3 is temporarily stored. Step 305: Data input time management unit a of analysis device a
7 monitors the actual time, that is, the data input time. Step 306: Data input time management unit a of analysis device a
7 determines whether or not the actual time has reached T2. Step 307: Data input time management unit a of analysis device a
7, when the actual time reaches T2, the analysis result at the analysis progress time T2 of the analyzer b is transferred from the input buffer unit a6 to the input unit a2. Step 308: The analysis calculation unit a3 fetches the analysis result of the analysis device b at the analysis progress time T2 from the input unit a2 together with data from the sensor in its own area, etc., and starts prediction analysis from time T2 based on the new data. I do.

It is to be noted that, here, the analyzing device a is the analyzing device b.
Although the case where the analysis result is received from the above has been described, the prediction analysis can be performed by the same procedure when the analysis device b receives the analysis result from the analysis device a.

By the way, without using the reservation method of the present invention,
As means for exchanging data between the analyzers, the following two methods are conceivable. The first method is, for example, in a river and a lake, the analysis period τa, τb and the analysis time dTa, d
This is a method of unifying Tb and synchronizing and performing analysis processing.
In the second method, the analyzers a and b always hold the analysis data at all times in the storage devices in the respective analyzers, and retrieve data at a predetermined time in response to a data transfer request from another analyzer. And send it out.

In the case of the first method, it is required to be able to follow the change of the earlier phenomenon, and it is necessary to perform the analysis up to a predetermined time by all the analyzers.
a, τb are unified, and the analysis time is dTa, dTb
Must be unified to the longer one. The processing amount of the analyzer per unit time is proportional to the analysis time dT, and the analysis period τ
Increases in inverse proportion to For example, river: τa = 5 minutes, d
Assuming that Ta = 30 minutes, lakes: τb = 1 hour, dTb = 4 hours, when the first method is adopted, the analysis device a requires eight times the analysis processing speed as compared with the so-called stand-alone system. In the analysis apparatus b, a 12-fold analysis processing speed is required. For this reason, a decision must be made as to whether to introduce high-speed hardware dedicated to the analysis processing or to reduce the amount of calculation while sacrificing the analysis accuracy without changing the hardware.

In the case of the second method, data of all times analyzed in the past is held in the storage device of each analyzer, and a data transfer request is received from another analyzer, and an analysis requesting data at a predetermined time is received. Send out to the device. The storage area is required by the number obtained by dividing the analysis time T by the time step width Δt. Therefore, for example, when setting Δt in the order of several seconds and performing analysis,
Each of the rivers and lakes requires at least several thousand times the storage area.

On the other hand, when the reservation method of the present invention is used, it is possible to avoid a demand for an improvement in processing speed and a remarkable increase in the storage area as in the conventional method.

Second Embodiment Next, a second embodiment of the water operation monitoring system according to the present invention will be described with reference to FIGS.

FIG. 5 is a block diagram showing the configuration of the analyzer in the second embodiment of the water operation monitoring system according to the present invention. Second Embodiment A second embodiment is a water operation monitoring system for analyzing lakes and marshes 12, rivers 13, and pipes 14 as analysis targets. The pipeline 14 is, for example, a pipeline for tap water buried underground in a city. Lakes 12 and rivers 13
Are connected by water channels 8 and 9. The water operation system includes a water supply facility 15 for pumping water from a river to generate tap water, and a sewage treatment facility 16.

The analysis device 17 for analyzing the lake 12 includes an input unit, an analysis operation unit, a transmission unit, an input buffer unit, a data input time management unit, and an analysis time management unit, similarly to the analysis device 1 of the first embodiment. Operate similarly. An analyzer 18 for analyzing the river 13 and an analyzer 19 for analyzing the pipeline 14
Is configured similarly to the analysis device 17 that analyzes the lake 12. Transmission control unit 20 of each analyzer 17, 18, 19
Controls the exchange of data with other analyzers. The address management unit 21 stores an address unique to each analyzer, and stores a request source address when a reservation is accepted. The wiring 22 is a communication line such as a LAN or a telephone line for communicating data.

The operation of each of the analyzers 17, 18, and 19 is the same as that of the first embodiment shown in FIG. 4, and data required at the next data input time is mutually reserved for other analyzers. The analysis proceeds while exchanging data. Example 2
In order to connect a plurality of analyzers, the transmission control unit 2
0 and an address management unit 21.

FIG. 6 is a flowchart showing a transmission procedure of the transmission control unit 20 of the analyzer 17 according to the second embodiment. Steps 600 to 604 are procedures for receiving a reserved analysis result and a reservation request from another analyzer, and steps 605 to 612 are procedures for transmitting a reserved analysis result and a reservation request of the user itself.

Step 600: The transmission control unit 20 determines whether there is any signal from the other analyzers 18 and 19. Step 601: If there is a signal from any of the other analyzers, it is determined whether the analysis result has been previously reserved for the other analyzers 18 and 19 or a reservation request for the other analyzers 18 and 19 has been made. I do. Step 602: If it is determined that the analysis result has been previously reserved for the other analyzers 18 and 19, the data is temporarily stored in the input buffer unit 6, and
Repeat 00 again. Step 603: In step 601, another analysis device 1
When it is determined that the request is a reservation request from any one of 8 and 19, the address management unit 21 registers transmission source information such as a transmission source address and a transmission request time. Step 604: Register the reserved time in the analysis time management section 4, and repeat step 600 again.

Step 605: If there is no signal from the other analyzers 18 and 19 in step 600, it is determined whether or not there is a reservation request signal from the data input time management unit 7. Step 606: When there is a reservation request from the data input time management unit 7, the address management unit 21 determines the address of the request destination. Step 607: Create reservation data requesting sending. Step 608: It is determined whether or not the other analyzers 18 and 19 are communicating, that is, are using a line. If the communication is in progress, step 608 is executed until the communication ends, and the end is waited. Step 609: After step 608, the reservation data is sent out, and after the sending out, step 600 is repeated again. Step 610: In step 605, if there is no reservation request signal, it is determined whether there is a transmission request signal from the transmission unit 5, and if there is no signal from the transmission unit 5, step 6
Repeat 00 again. Step 611: When the signal is in the output state from the transmission unit 5, the address management unit determines the address of the other party based on the transmission source information recorded in step 603. Step 612: Create analysis result data for sending out. Step 608: It is determined whether or not the other analyzers 18 and 19 are communicating, that is, are using a line. If the communication is in progress, step 608 is executed until the communication ends, and the end is waited. Step 609: After the step 608 is completed, the analysis result data is sent out.
repeat. Through the above operation, the respective analyzers mutually make reservations.

FIG. 7 is a diagram showing an example of data stored in the address management unit 21 in step 603. The address management unit 21 has a data table including the address of the requesting analysis device and the time requested by the analysis device. This data table is sequentially added at the time of registration in step 603. In step 611, the address of the other party is determined from the time data, and data for sending out is created. When the sending data is created, the address of the other party to be sent is deleted from the data table.

FIG. 8 is a diagram showing an example of the structure of the signal of the sending data. In the second embodiment, data is transmitted by serial transfer. The destination address 23 indicates the address of the destination to which data is to be transferred, and the own address 24
Indicates your address. Data type 25 is
It distinguishes between a reservation request to the other party and a response to the other party's request. The data length 26 indicates the size of the data 27. Data 27 indicates that when requesting a reservation from the other party,
It becomes the requested time data, and in the case of a reply to the request of the other party, it is the analysis result. The spare signal 28 is, for example, a transmission error detection / error correction signal such as a checksum.

With the data format having such a configuration, in the second embodiment, the data of the required analysis progress time can be mutually reserved and exchanged between the analysis device 17, the analysis device 18 and the analysis device 19.

FIG. 9 shows an example of the combination of the analysis period of the object to be analyzed by each of the analyzers 17, 18, and 19, that is, the change time of the form and the phenomenon of the object in lakes, rivers, and pipelines, and the analysis period τ and the analysis time dT suitable for the analysis. FIG.

The form of the analysis object indicates the distinction between the open channel and the closed channel. Generally, lakes and rivers are open channels,
Changes in the flow rate and water level propagate in the space at a flow velocity. On the other hand, in some cases, the pipe is an open / close type in which the entire pipe is filled with water, and when the pipe becomes a closed channel, a change in the flow rate propagates in the pipe at the speed of sound. In relation to the above-described embodiment, for example, when considering the water level and the flow rate, the change time of the phenomenon greatly changes depending on the scale of the target, but in lakes and marshes, 1
Days to days, for rivers, hours, and for pipelines, minutes. As a result, it is an approximate value. In the case of a lake, τ = 1 hour and dT = about 24 hours. In the case of a river, τ = 5 minutes and dT = 1 hour. In the case of a pipeline,
τ = 30 seconds and dT = about 5 minutes.

For example, as in the first embodiment, when the analysis period τ and the analysis time dT are unified in all the analyzers and the analysis processing is performed, it is necessary to set τ = 30 seconds and dT = 24 hours. . Similarly, in the calculation, the analysis device 17 calculates
A 120-fold operation is performed, the analysis device 18 performs a 240-fold operation, and the analysis device 19 performs a 288-fold operation. Obviously, the burden of the analysis process and the storage space of the large storage device for exchanging the analysis results are significantly reduced.

In the above description, the embodiment in which the present invention is applied to the analysis of flow phenomena in rivers, lakes, marshes, and pipelines has been described. However, the present invention can also be applied to analysis of chemical reactions and ecosystem behavior. If the optimal analysis period τ and the analysis time dT are set for each system and system in the same manner as described above, the burden of the analysis process can be reduced as compared with the conventional method.
The storage space of the storage device for exchanging analysis results can be significantly reduced.

[0050]

According to the present invention, the analysis calculation unit can reserve the analysis time at the analysis time management unit of another analysis device so as to transmit the analysis result at the analysis progress time corresponding to the next data input time. Also, the analysis results at the analysis progress time corresponding to the next data input time can be reliably taken in from analysis devices having different analysis processing speeds and / or analysis periods.

On the requesting analyzer side, if data is sent out each time the result of analysis at the time of receiving the reservation is output, there is no need to store the data thereafter, and the exchange of the analysis result with another analyzer is not necessary. Therefore, it is not necessary to have a large storage device.
