Water Usage Monitoring System

Abstract

The invention discloses a monitoring system for water usage, which can grasp the variation in water quantity requirements measured by a measurement device for water use and realize low communication cost. The monitoring system for water use comprises a plurality of measurement devices and a monitoring device for water use. The measurement devices are operated as follow: recording the measurement value of water capacity detected within a prescribed cycle according to time sequence as a first measurement record (38) in a first storage device (34); and transmitting the non-transmitted part of the first record (38) in a cycle which is a specific communication cycle and is longer than the measurement cycle. The monitoring device for water use is connected to measurement devices (3) by a wired or a wireless network. The monitoring device for water use records the received the measurement values from measurement devices according to time sequence as a second record (59), and tabulates data displayed by an input / output device (6) of the second record.

Description

technical field [0001] The present invention relates to a water usage status monitoring system related to a monitoring device that transmits and receives data from a plurality of measuring devices that measure water usage status through a communication line, and collects data. Background technique [0002] Currently, a measuring device for measuring the amount of usage of a sewer has a display unit for displaying a measured value, and a manager visually checks the measured value to grasp the amount of usage for a certain period of time. Recently, a measurement device equipped with a communication unit has been introduced in heavy snow areas and emerging countries, and a system that automatically checks the meter by sending the measured value to the management server at regular intervals. [0003] For example, in the technique described in (Patent Document 1), it is disclosed that the state change type is stored in a memory for comparison. [0004] (Patent Document 2) disclo...

Problems solved by technology

However, these problems have not been considered in the aforementioned prior art

[0020] On the other hand, by accumulating the measurement amounts of each measuring device, it is possible to grasp the overall usage amount or the usage amount in a specific area, but as mentioned above, when communication is performed sequentially, an increase in communication cost becomes a problem.
