Description

[0001]
BACKGROUND OF THE INVENTION
The present invention relates to a water supply management support system and a water supply management support method, and in particular, provides end-of-water information using a network line to a water utility, a maintenance management company, or a company that performs planning and design. The present invention relates to a water management support system and a water management support method that are suitable for use.
[0002]
[Prior art]
In order to properly plan, design, and maintain water supply facilities, it is necessary for each business entity and each company to secure sufficient staff. However, securing such staff is a major burden on the implementation of water and sewage projects, as conditions such as the financial situation of the business entity and personnel composition must be met. Management of tap water pressure and water quality is indispensable for improving services to consumers, but there are also small and medium-sized business entities that are not necessarily properly managed at present.
[0003]
For example, residual chlorine, which is an important water quality item for tap water, tends to be excessive in actual operation because the lower limit is stipulated by the Water Supply Law, and generation of off-flavors and carcinogenic substances is regarded as a problem. Yes. In order to solve such problems, the quality of the terminal water must be improved by adding additional chlorine in the reservoir and optimizing the residence time by developing the water pipeline. To that end, it is necessary to keep track of terminal water quality and water pressure information. In particular, in the case of water supply that is becoming more widespread, in order to ensure the quality of tap water supplied to end users, it collects water quality information in the water supply area, as well as grasps the current situation, leveling service, Maintenance management, planning, and design aiming at computerization are indispensable. In addition, appropriate investments must be made through communication with customers in difficult financial resources.
[0004]
Currently, a technique using a network such as the Internet is applied for the purpose of managing a wide area system such as water supply, and as a conventional technique for collecting and managing water end information, Japanese Patent Application Laid-Open No. 2002-181806, or It describes in Unexamined-Japanese-Patent No. 2002-316141.
[0005]
Multiple water supply areas will be connected in the water supply wide area, pipe connections will be changed in the water supply block, the facilities such as aging pipes are in the period of renewal, changes in the water source environment, etc. In response, the properties of tap water from the faucet at home have continued to change. For leveling and sophistication of water supply services, it is most important to collect as much water quality information as possible at the end, such as faucets for houses in the water supply area, at as low a price as possible and to grasp the current situation in the wide water supply area. is there.
[0006]
Japanese Patent Laid-Open No. 2002-181806 provides a water quality monitor (sensor) at the water supply end in a water supply area, receives measurement data relating to the water quality that is the output of the monitor, and provides water quality monitoring and water quality information in real time from a remote location The service to be described is described. Similarly, JP-A-2002-316141 describes that water supply information sensors are installed at a plurality of locations in a water supply target area.

[Problems to be solved by the invention]
However, the installation of a water quality sensor at the end of the water supply requires high costs because it requires connection work with water pipes and water storage tanks, power supply work, circuit work, and securing space. In addition, since an apparatus that realizes real-time measurement has an automatic calibration and cleaning function, the apparatus becomes complicated, so that there is a problem that a specialized staff member has to deal with maintenance of the apparatus. Furthermore, there is a problem that not only the installation location is limited, but also labor is required to change the position of the water quality sensor once installed. In particular, it is difficult to measure water quality information at the end, such as a water inlet to a general house.
[0009]
In addition, since the water quality sensor is fixedly installed and transmits time-series data, it is necessary to modify and modify the reception function every time a sensor is added or the position is changed. Furthermore, in a system that assumes that a water quality sensor sends time-series data, data sent from an arbitrary point such as temporary sensor data and data measured by humans cannot be handled. For this reason, there is a problem that water quality data measured irregularly and data measured as emergency measures such as disasters cannot be effectively used.
[0010]
In the above-described conventional technology, even if it is attempted to manage terminal water supply information in a wide water supply area, it is difficult to proceed stably and stably for a long period of time because it is limited in cost and installation location.
[0011]
The present invention has been made to solve the above-described problems, and an object of the present invention is to flexibly and cost-effectively collect and distribute wide-area waterworks information in a water supply area.
[0012]
