Water desalination device using label for monitoring and control method thereof

Abstract

The present invention discloses a water desalination device using labels for monitoring and a control method thereof. The device comprises a bitter water pond, a first water pump, a pre-assembly, a pressure-regulating valve, a reverse osmosis assembly, a clean water pond, a control cabinet, four labels and a reader. The bitter water pond is equipped with a bitter water pond liquid level sensor, the water outlet end of the first water pump is provided with a first flow sensor, the water outlet end of the reverse osmosis is provided with a pH value sensor, and the clean water pond is provided with a clean water pond liquid level sensor. The four labels are defined as a first label, a second label, a third label and a fourth label. The switch of the first label is electrically connected with the bitter water pond liquid level sensor; the switch of the second label is electrically connected with the pH value sensor; the third label is electrically connected with the first flow sensor; and the fourth label is electrically connected with the clean water pond liquid level sensor. According to the invention, the labels are energized when a fault occurs, so that the labels can be read by a reader carried by the user to achieve notify the user, and the user does not need to apply real-time monitoring.

Description

technical field [0001] The invention relates to the technical field of desalination of brackish water, in particular to a desalination equipment monitored by tags and a control method thereof. Background technique [0002] Saline-alkali soil is a general term for saline soil and alkaline soil, and its salt content is too high (over 0.3%), so that crops are low-yield or unable to grow. Because most of the soluble salt in the saline-alkali soil is sodium salt, the soil is heavy, the soil colloid is dispersed and emulsified, the air permeability is poor, it swells and becomes muddy when it encounters water, and it shrinks hard after dehydration, which seriously affects the germination of crop seeds and the normal development of crops. In addition, soil sodium ions Excessive alkaline reaction will directly damage plant tissue, and the root system of crops is also perishable, affecting nutrient conversion, making phosphorus fertilizer and trace elements insoluble and invalid. Th...

Problems solved by technology

[0003] At present, desalination equipment is usually used to desalinate brackish water, but the current desalination equipment needs to be monitored in real time on site, which takes up the user's time and is unscientific
