Embodiment Construction

[0033] The embodiments of the present invention will be described with reference to the drawings.

[0034] figure 1 It is a conceptual configuration diagram of the water use condition monitoring system according to the embodiment of the present invention.

[0035] In the water use condition monitoring system S of the embodiment, for example, a water distribution pipe 1 in a water distribution block (block) is provided with a pipe 1j to a household 2 in need to measure the flow rate (amount of water used) and the water pressure of the water supply. Measuring device (waterway instrument) 3.

[0036] The water use condition monitoring system S is configured to include: a network 4 for data transmission of the measurement device 3, a water use condition monitoring device 5 for managing measurement equipment information related to each measurement device 3 and its measurement values, and The monitor 6 for confirming the measured value of each measuring device 3 and the information of the...

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 use condition monitoring system related to a monitoring device that transmits and receives data from a plurality of measurement devices that measure the water use condition through a communication line, and performs data collection. Background technique [0002] Currently, measurement devices that measure the amount of water used are equipped with a display unit that displays the measured value. The administrator can visually check the measured value and grasp the amount of use for a certain period of time. Recently, in heavy snowy areas or emerging countries, a system that has a communication unit in a measuring device and sends the measured value to the management server in a fixed period has been introduced to perform automatic meter lookup. [0003] For example, in the technique described in (Patent Document 1), it is disclosed that the state change category is stored in a memory for comparison. [0004] In (Patent ...
