Display method for low-power intelligent water meters

Abstract

The invention discloses a display method for low-power intelligent water meters. The display method includes acquiring data collected by a plurality of metering units; judging whether the data conform to display conditions or not, carrying out display processing on the data which conform to the display conditions and carrying out internal storage processing on the data which do not conform to the display conditions. Each metering unit comprises at least one of a pulse or ultrasonic fluid sensor and an internal clock, flow information of water in meter bodies of the intelligent water meters can be acquired by the pulse or ultrasonic fluid sensors, and reading time information of the meter bodies of the intelligent water meters can be acquired by the internal clocks. The data are demonstrated on display units of electronic ink screens by the aid of different marks according to the flow information of the water and the reading time information of the meter bodies of the intelligent water meters during display processing. The display method has the advantages that displayed information can be kept without power supply for a long time, backlight sources can be omitted, accordingly, consumption of the backlight sources can be saved, energy consumption of batteries in the intelligent water meters can be reduced, and low-power effects can be realized.

Description

technical field [0001] The invention relates to an intelligent water meter for displaying water consumption and metering of the water meter on an electronic screen, in particular to a display method of a low-power consumption intelligent water meter. Background technique [0002] At present, the smart water meters displayed on the electronic screen on the market use LCD screens, referred to as LCD smart water meters. LCD screen smart water meters are generally powered by batteries. They have the functions of measuring water volume through fluid metering sensors, using LCD screen electronic display, measuring and controlling user water consumption according to product functions, automatically completing step-by-step water charges, and storing water meter data. Power supply, especially strict requirements on the power consumption of smart water meters; [0003] The current use of liquid crystal smart water meters has the following deficiencies or defects: [0004] 1. In orde...

AI Technical Summary

Problems solved by technology

[0004] 1. In order to reduce power consumption, the LCD screen smart water meter usually does not display the LCD screen, and only displays the data once when the user triggers it (by swiping the card or button, etc.), which is inconvenient for the user to check the water consumption;

[0005] 2. The LCD screen also consumes battery power when it is not displaying data, resulting in high overall power consumption of the smart water meter and not saving energy;

[0006] 3. Especially when the smart water meter fails, since the LCD screen does not display information such as the total amount of water used before the failure, when the faulty water meter is replaced on site, the customer's water consumption cannot be determined and settled, which will cause users and water meter management departments Consumption disputes caused by the inability to determine the water consumption on site, which limits the promotion and application of electronic water meters without mechanical dials
