specific Embodiment approach 1

[0053] Embodiment 1: Combining figure 1 To specifically describe this embodiment, the valve closing alarm device for building water appliances described in this embodiment includes a first electromagnetic water meter 1 , a second electromagnetic water meter 2 , a remote data transceiver module 3 and a data centralized processing module 4 ;

[0054] The first electromagnetic water meter 1 is located on the entry pipe of each building, and is used to collect the instantaneous flow and instantaneous pressure of the water at the entry pipe, and send the collected data to the remote data transceiver module 3;

[0055] The second electromagnetic water meter 2 is located at the end of each water supply riser 5 of the building, and is used to collect the instantaneous flow and instantaneous pressure of the water at the end of the water supply riser 5, and send the collected data to the remote data transceiver module 3;

[0056] The remote data transmission and reception module 3 is us...

specific Embodiment approach 2

[0074] Embodiment 2: This embodiment further describes the valve closing alarm device for construction water appliances described in Embodiment 1. In this embodiment, there are multiple water supply risers 5, and each water supply riser 5 is provided with a terminal at the end. There is 1 second electromagnetic water meter 2.

[0075] The main pipe of the household pipe can be connected to multiple water supply risers 5, which is suitable for a single building and multiple buildings with multiple water supply risers 5. Adding a second electromagnetic water meter 2 at the end of each water supply riser 5 can be used. It is composed of a fully functional water appliance closing valve alarm device.

specific Embodiment approach 3

[0076] Specific implementation three: combination figure 2 This embodiment is described in detail. This embodiment further describes the valve closing alarm device for building water appliances described in the first embodiment. In this embodiment, an installation condition with only one building water supply riser 5 is taken as an example. , the data centralized processing module 4 processes the received data according to the transient flow inverse problem theory, and closes the valve when there is an abnormal situation of water consumption, which specifically includes the following steps:

[0077] Step 1. Establish a water coefficient array a, a=(a 1 , a 2 , …, a j , ... a N ) T , and initialize the array so that a = (0, 0..., 0) T , a j is the water coefficient of the jth branch pipe on the water supply riser 5, and N is the total number of branch pipes on the water supply riser 5;

[0078] Step 2, receive t i At the moment, the data collected by the first electrom...

Abstract

The invention discloses a valve closing alarm device for a building water appliance, relates to the building water-saving field, and aims to solve the problem that water resource is wasted as a waterappliance is forgotten to close as a result of subjective reasons of a user and the water appliance is damaged when the user goes out. A first electromagnetic water meter is positioned on an inlet tube for acquiring instantaneous flow and instantaneous pressure of water at the inlet tube, and sending the acquired data to a remote data transceiver module; a second electromagnetic water meter is positioned at the tail end of a water feeding vertical tube for acquiring instantaneous flow and instantaneous pressure of water at the tail end of the water feeding vertical tube, and sending the acquired data to the remote data transceiver module; the remote data transceiver module is used for sending received data to a data centralized processing module; and the data centralized processing moduleis used for processing received data according to the transient flow inverse problem theory, and performing valve-closing alarm in a water consumption anomaly condition. The valve closing alarm deviceis suitable for building water saving.

Description

technical field [0001] The invention relates to the field of building water saving, in particular to a valve closing alarm technology for building water appliances. Background technique [0002] my country is rich in surface water resources, but its per capita water resources are at the bottom of the world's water resources level, and it belongs to a country with severe water shortages. With the rapid development of society, the population has increased sharply, and the scale of cities has continued to expand, further exacerbating the problem of urban water stress. Among them, a large proportion of urban water consumption is building domestic water, accounting for about 60% of the total urban water consumption. The domestic water in buildings is mainly used for water utensils: faucets, toilets, and shower nozzles. The study found that the water consumption of these three parts accounted for 40%-50%, 30%-40%, 5%-8% of the total water consumption respectively. Forgetting to ...
