設備の殆どの割合を占めている。In the above prior art, it is necessary to install flow meters, pressure gauges, and the like in all pipelines in order to monitor water leakage due to breakage of a water pipeline. However, it is actually difficult to install the above-mentioned instruments in all the pipelines, like the plumbing equipment of the water supply facility, in terms of facilities and costs. On the other hand, for example, in a plant where there is no flow meter or pressure gauge in the distribution pipe, water is pumped to a reservoir on a hill, and the water flows naturally from the reservoir to general consumers, it is necessary to monitor the leakage. There was no problem. But,
Such simple plants account for most of the water supply facilities in small and medium-sized cities in Japan.

It has a processing unit, and when the actual water level exceeds the water leakage occurrence water level pattern, it is resolved by determining that water leakage has occurred and notifying. Here, the predicted water level pattern plan processing unit creates a water level upper limit value (permissible) pattern and a water level lower limit value (permissible) pattern based on the water level plan (predicted) pattern, stores them in the predicted water level pattern memory, and monitors water leakage. The calculation processing unit compares the actual water level on the day of the water leakage monitoring with these patterns and monitors the operation state of the equipment installed in the water pipe.

The plant 24 uses a pump 26 to transmit water from a distribution reservoir A25 located at a relatively low place to a distribution reservoir B28 located at a higher place, and tap water is distributed from the distribution reservoir B28 to general consumers 29 under natural flow.

る。The daily water demand pattern of the consumer 29 is as follows:
It is generally known that every day is similar to the pattern shown in FIG. This similarity depends on the day of the week,
Water demand varies depending on weather, temperature, humidity, and the like. When the customer uses the tap water in the demand pattern of FIG. 2, the water supply manager operates the pump 26 as shown in FIG. 4 in order to prepare the tap water, but the actual demand is not visible. Therefore, the manager will deal with the amount of water stored in the reservoir B28. For example, in FIG. 2, if a water demand peak is expected around 8:00 am as shown by a daily demand pattern, the water level of the reservoir B28 is stored up to near full before that, and suddenly stored. Be prepared for a dynamic demand. When such an operation method is performed, the water demand pattern of the consumer 29 can be replaced with the operation pattern of the reservoir B28, that is, the daily reservoir operation pattern of FIG. It suffices to set the target value of the water level of B28 for each time zone and operate the pump. The daily operation pattern of the reservoir in FIG. 3 is a water level plan (prediction) pattern of the reservoir B28. When the administrator operates the pump 26 based on the water level plan (prediction) pattern in FIG. 3, if the pipeline is broken, water cannot be supplied to the distribution reservoir B28, and the difference between the planned water level and It will spread.
