A matrix valve-controlled water meter system and valve control method thereof

Abstract

The invention relates to the technical field of intelligent water meters, in particular to a matrix valve-controlled water meter system and its valve control method. The invention uses multiple valve-controlled water meter units to realize data interaction with a router unit, and collects modules, water meter memory, and clock modules. Both the valve control module and the valve control module are connected to the main control module through the communication line, and the router unit supplies power to the main control module. The invention adopts the design scheme of ultra-low power consumption. The valve-controlled water meter has an independent main control module and motor drive function, and cooperates with the router unit to form a matrix valve control system, and realizes data interaction with the router unit through a single communication line. The valve-controlled water meter unit is managed by the router unit in a unified manner. The unified data collection and upload is the customer management system. On the basis of reducing the overall cost, the maintenance workload is greatly reduced. The present invention adopts multi-mode valve closing operation, that is, operates in three units of fully closed gear, exhaust gear and fully open gear, and is suitable for valve closing operations in different situations.

Description

technical field [0001] The invention relates to the technical field of intelligent water meters, in particular to a matrix type valve-controlled water meter system and a valve-controlled method thereof. Background technique [0002] With the development of society, the demand for tap water is increasing year by year, people's awareness of environmental protection is increasing, and water resources are increasingly scarce. In response to the unified deployment of energy price programs by the National Development and Reform Commission, saving and effectively using water resources has become more and more popular in the international community. In addition, fresh water resources are directly related to economic benefits, so effective monitoring and management of tap water resources is very important and urgently needed. At present, most of the control valves of water meters on the market have a single function, and when the faucet is used for the first time after a period of wa...

Problems solved by technology

Since each single intelligent valve-controlled water meter requires a complete set of data transmission module, power supply and power management module, its equipment cost is relatively high

In addition, because the single intelligent valve-controlled water meter is aimed at the maintenance of a single meter, especially for the customer group with a large amount of usage such as industrial and civilian meters, the maintenance workload is very large.

[0010] The valve control function of the existing water meter with valve is single, and at the same time, there is a large amount of gas in the water pipe during the water supply stage after the water company shuts off the operation. Trouble, at the same time, there is sediment and rust in the water after the water supply, which cannot be used for domestic water. This part of the water is wasted, and the user is very concerned about this, which affects the user's personal interests.
