A control method for desalinated water equipment monitored by tags

Abstract

The invention discloses a method for controlling desalinated water equipment monitored by labels. The equipment includes a brackish water tank, a first water pump, a pretreatment component, a pressure regulating valve, a reverse osmosis component, a clean water tank, a control cabinet, four labels and a reader A brackish water tank liquid level sensor is provided in the brackish water tank, a first flow sensor is provided at the water outlet of the first water pump, a pH value sensor is provided at the water outlet of the reverse osmosis component, and a clean water tank liquid level sensor is provided in the clean water tank. The four labels are respectively defined as the first label, the second label, the third label and the fourth label, the switch of the first label and the liquid level sensor of the brackish water tank, the switch of the second label and the pH value sensor, the third label and the A flow sensor and the fourth label are electrically connected to the liquid level sensor of the clear water tank. Therefore, after using the present invention, the tag will be energized when a fault occurs, so that it can be read by the reader carried by the user, so as to achieve the purpose of notifying the user, and does not require real-time monitoring by the user.

Description

technical field [0001] The invention relates to the technical field of desalination of brackish water, in particular to a control method of desalination equipment monitored by tags. 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. Therefore, so...

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
