Description

External 24v alternating current power supply's wisdom water gauge

Technical Field

The utility model relates to a verifying attachment field particularly, relates to an external 24v alternating current power supply's wisdom water gauge.

Background

The intelligent water meter is characterized in that a photoelectric sensing device is additionally arranged on the traditional mechanical water meter, the reading of manual meter reading is converted into numbers, and the numbers are transmitted to a background database in a wireless or wired Mode (MODBUS). At present, the intelligent water meter is well applied to the field of remote meter reading; in the field of remote meter reading, data are acquired and uploaded once per month basically by each meter, and a battery built in each meter can support several years, so that most of domestic intelligent water meters are powered by built-in batteries. Water is a non-renewable precious resource, and the Shanghai Water administration have been granted a plurality of policies in recent years to urge water consumption units (especially the large-scale water consumption units occupying a plurality of buildings) to establish a real-time water efficiency monitoring and management system. In the last two years, under the guidance of relevant departments of the water administration, the company builds a water efficiency real-time monitoring and management system for 2 clients. Each client (scale water consumption unit) needs to install dozens of intelligent water meters (in a water consumption pipe network of the user), and by means of an existing local area network and (MODBUS) data collector of the user, the users need to collect data every 5-10 minutes and upload the data, and according to comparison of the real-time data and a database, the users can master the water consumption efficiency of each department of the unit in real time (if the water consumption efficiency is wrong, the water consumption efficiency can be immediately corrected). All of the 2 items were successfully implemented; but we find that our staff need to change the battery for each intelligent water meter every month, because the intelligent water meter consumes a large amount of electricity each time data is collected and transmitted; according to the specified sampling frequency, the battery in the meter cannot support the intelligent water meter to continuously work for 2 months; this factor becomes a bottleneck restricting the large-scale popularization of such services. At present, although some intelligent water meters adopt batteries and 12V direct current dual power supplies for power supply, 12V direct current comes from a 220V alternating current adapter, but the cost for laying 220V alternating current power supply is higher at some water meter positions.

An effective solution to the problems in the related art has not been proposed yet.
