Description

technical field

[0001] The invention relates to an intelligent heat meter for displaying heat consumption and measurement on an electronic screen, in particular to a display method for a low power consumption intelligent heat meter. Background technique

[0002] At present, the smart heat meters displayed on the electronic screen on the market use LCD screens, referred to as LCD smart heat meters. LCD screen smart heat meters are generally powered by batteries, with the ability to measure heat consumption through fluid metering sensors, use LCD screen electronic display, measure and control the heat used by users according to product functions, automatically complete the ladder heating fee, and store heat meter data and other functions; using battery power supply, the power consumption requirements for smart heat meters are particularly strict;

[0003] The current use of LCD screen smart heat meters has the following deficiencies or defects:

[0004] 1. In order to reduce...

Examples

Embodiment example

[0054] Such as figure 2 As shown, after the display of the electronic ink display unit is completed, the display feedback circuit will feed back to the data processing control unit, and the drive unit of the data processing control unit disconnects the power supply switch of the electronic ink display unit. No power supply is required to achieve the effect of the lowest energy consumption of smart heat meters.

[0055] Such as image 3 As shown, the display data content of the electronic ink display includes time, total heat data and the instantaneous temperature of the fluid. Under long-term display conditions, the number of screen refreshes can be reduced as much as possible. The screen heat meter consumes less energy and consumes less power in terms of screen display refresh.

[0056] Such as Figure 4 As shown, a display method of a low-power smart heat meter, including

[0057] Step 1: collect the current energy (L1) and time data (H1) used by the heat meter to the d...
