Description

Remote monitoring system, remote monitoring method, remote monitoring program, image creating apparatus, image creating method, and image creating program

Embodiments described herein relate generally to a remote monitoring system, a remote monitoring method, a remote monitoring program, an image creation apparatus, an image creation method, and an image creation program.

Regarding the technology for displaying time-series data of the amount of water from a water source such as a river network around a drainage station, a technology for displaying a river network schematically and placing a place name and a window on the water level measurement point side of the river network is known. (For example, refer to Patent Document 1). In this technique, the current measured water level is displayed in a window to display time-series data of the amount of water. This makes it possible to spatially display the water level distribution at the current time on a map of the river network. Furthermore, in this technique, the water level at each water level measurement point ahead of a predetermined time is predicted, and time-series data of the predicted water level is displayed.
In addition, a technique for predicting the collapse or drought of a reservoir in a short time using the current water level data and rainfall data of the reservoir is known (for example, see Patent Document 2). In this technique, whether or not a breakdown or drought occurs is determined by comparing the result of predicting a change in the water level with the height data that serves as a reference for determining whether or not the reservoir has been destroyed and drought.

Japanese Patent Laid-Open No. 9-111172 JP 2013-174983 A

In the above-described technique, an operator browses water amount measurement data of a water source such as a river network, and the operator operates the time series on a map to display the water amount measurement data. Moreover, in order to assist the operation by the operator, a prediction simulation of the water level of the water source is performed.
If the river water system is relatively simple and the river management facilities have many pumping stations, it is not difficult to grasp the state of the entire water system even with this method.
In recent years, water discharge channels and diversion channels have been newly established for water interchange between rivers, and the river network has become increasingly complex and widespread. With the above-described display method, it is difficult to properly grasp the state of the entire water system. Specifically, when the river network is widened and complicated, it is necessary to increase the number of windows for displaying data accordingly. Therefore, a lot of numerical data is arranged on the screen, and the screen becomes very difficult to understand. Furthermore, although the water level data can be spatially displayed, only the water level distribution at the current time or a specific time can be displayed, and cannot be displayed in time series. Furthermore, if the number of trends for predicting the water level increases, the display becomes very difficult to understand, and the water level data can be displayed temporally but not spatially.
The foregoing applies not only to river water systems but also to displaying time-series data of the amount of water from wells and other water sources.

In addition, it is considered to predict the breakdown and drought of multiple reservoirs. In the above-described technique, it is necessary to prepare in advance height data serving as a reference for the breakdown and drought of each of the plurality of reservoirs.
Here, it is considered to predict the land subsidence near the water source using the water level data of the water source such as a well. In this case, it is necessary to prepare water level data as a reference for land subsidence in the vicinity of the water source, as in the case of predicting breakage or drought in a plurality of reservoirs. Moreover, since the conventional monitoring system does not measure the water source elevation, there is a problem that the land subsidence cannot be predicted.
The present invention has been made in view of the above circumstances, and a first object is to provide a remote monitoring system, a remote monitoring method, and a water monitoring method that can easily grasp the water level and / or water quality of the water source even when the water source is wide-area.

In the vicinity of the bottom of the protective tube 16, a water intake 16 a is formed at the position of the aquifer X when the protective tube 16 is inserted into the excavation hole H. A wire mesh 17 for preventing sand and the like from entering the protective tube 16 is attached to the intake port 16a. “Gas impervious” means not allowing gas to permeate from the protective tube 16 to the soil such as the aquifer X.

As the pump 12 and the pumping pipe 13, a known pump and pumping pipe used for a well can be used.

The water level gauge 19 measures the water level of the ground water W that springs into the well. An example of the water level gauge 19 is a bubble type water level gauge. The bubble-type water level meter calculates the water level by measuring the pressure required to send bubbles to the bottom of the water with a bubbler tube whose open end is located at the bottom of the water. The water level gauge 19 transmits water level information including the measurement result of the water level of the ground water W to the monitoring device 112.

When the water level information is acquired, information indicating one or both of the groundwater membrane filtration system 100c and the groundwater membrane filtration system 100d and a water level information display image representing the water level information are created.

The display image creation unit 264a refers to the measurement information table 274a when the information requesting the elevation information display image is included in the display request information, and either the groundwater membrane filtration system 100c or the groundwater membrane filtration system 100d or Information indicating both and altitude information stored in association with one or both of the groundwater membrane filtration system 100c and the groundwater membrane filtration system 100d are acquired.

Is output to the communication unit 250a. When pumping up the water source, especially in the case of groundwater and lake water, the monitoring level should be as short as possible because the water level drops in minutes. Specifically, the display image creation unit 264a preferably updates any one of the water level elevation information display image, the water level information display image, and the elevation information display image every period shorter than five minutes, at least every two minutes. It is more preferable to update.

The analysis unit 266a acquires measurement information stored in the measurement information table 274a of the storage unit 270a. When the analysis unit 266a acquires the measurement information, the analysis unit 266a predicts ground subsidence by analyzing the water level information included in the measurement information.
Specifically, the analysis unit 266a stores information indicating the initial water level (static water level), and calculates a value obtained by subtracting the initial water level from the acquired water level information. Here, the water level at the reference date and time may be used as the initial water level. The analysis unit 266a determines the risk of ground subsidence according to the subtracted value. For example, if the subtracted value is -5m or more, the risk is "Risk 1" indicating the lowest risk. If the subtracted value is -10m or more and less than -5m, the risk is the second. “Risk 2” indicating that the risk is low, and if the subtracted value is less than −10 m, “Risk 3” indicating that the risk is the third lowest. Further, the analysis unit 266a may obtain the elevation information included in the measurement information, and verify the prediction by confirming whether or not ground subsidence has occurred from the elevation information.

Here, the relationship between the groundwater level and land subsidence will be described. When groundwater is pumped at an appropriate pumping amount, a rapid decrease in water level is unlikely to occur because the amount of groundwater pumping and recharge is balanced. In this case, voids or the like hardly occur in the formation in the period of the groundwater basin, and land subsidence hardly occurs.
Conversely, if the balance between groundwater yield and recharge is lost, the groundwater level will drop due to excessive pumping, etc., and even after waiting for a certain time after pumping, the groundwater level (static water level) will not recover to the initial value, It is measured as a concrete change in the groundwater level, such as the water level during pumping (dynamic water level) gradually decreasing. When such a change in the initial water level (static water level) or a change in the dynamic water level (water level during pumping) is detected from the water level information acquired from the water level gauge 19, there is a water source from which the water level information is measured. It can be determined that the risk of ground subsidence has increased.
Therefore, the analysis unit 266a stores information indicating the initial water level (static water level), and calculates a value obtained by subtracting the initial water level from the acquired water level information. The analysis unit 266 determines the risk of ground subsidence according to the subtracted value. Furthermore, the analysis unit 266a analyzes the cause of ground subsidence by determining whether or not the balance between the pumped amount of groundwater and the amount of recharge is lost according to the subtracted value.

Moreover, you may make it the analysis part 266a acquire the time series data of water level information from the measurement information memorize | stored in the measurement information table 274a of the memory | storage part 270a.
