However, the cost of using pulse counters is high. If ordinary water purification equipment uses pulse counters, the cost of water purification equipment will be greatly increased; the second method uses the time when the pump is turned on to calculate the water flow, and the cost is much lower than using pulse counters to count the water flow. , by counting the flow of water flowing through the pipeline per unit time, and using the time when the pump is turned on to count the water flow
However, in a fixed pipeline, the greater the water pressure, the greater the water flow rate, and the greater the water flow per unit time. Due to the influence of external factors such as water supply sources or water supply pumps, the water pressure in the pipeline may continue to change, resulting in The water flow rate varies greatly per unit time, resulting in a large statistical error when calculating the water flow rate using the time when the pump is turned on

The invention discloses a water flow statistics method and device. The method is used for utilizing the pump starting time to compensate water flow during water flow statistics, current water pressure can be estimated according to a water pressure state switching mode to obtain a water pressure estimation value at a next moment due to the water flow and the influence of water pressure, the compensated water flow is obtained according to the preset relation between the water flow and the water pressure and the water pressure estimation value, water flow statistics errors caused by water pressure change can be decreased by estimating the water flow, and the accuracy of water flow statistics by utilizing the pump starting time is improved.
Description
technical field [0001] The invention relates to the technical field of detection, in particular to a water flow statistics method and device. Background technique [0002] With the progress of industrial civilization and social economy, the natural environment has been severely damaged, people's drinking water sources have also been seriously polluted, and the quality of drinking water has gradually decreased. With the improvement of living conditions, people pay more and more attention to the safety and health of diet, and the requirements for the quality of drinking water are also getting higher and higher. In such an era background, all kinds of water purification equipment came into being and gradually integrated into all aspects of people's daily life. The calculation of water flow is a very important part of the water purification system, which is related to the service life of the filter element and the quality of purified water. [0003] There are usually two exist...
