Secondary water supply automatic control system

Abstract

The invention discloses a secondary water supply automatic control system, which comprises a water supply monitoring system for measuring and detecting pressure and water supply flow of a municipal water inlet pipeline; a water tank monitoring system used for detecting water flow in the municipal water stored in the water tank; a water supply monitoring system used for carrying out pressure and early warning detection on the municipal water outlet pipeline; a power distribution monitoring system used for providing a power supply for the secondary water supply automatic control system and monitoring the power distribution system; and a parameter control system. The system is advantaged in that the PLC (Programmable Logic Controller) control technology and a frequency conversion control technology are adopted, and a PLC is used for carrying out monitoring and energy-saving control on a water supply system, water supply equipment, a power supply system and power supply equipment of a pump room; therefore, the system is advantaged in that the system has a strong energy storage function, enough adjusting volume and stable water supply pressure, and is simple to control, efficient and energy-saving, so normal operation of a tap water pipe network and reliability of subsequent water supply are ensured.

Description

technical field [0001] The invention relates to the technical field of municipal domestic water supply systems, in particular to a secondary water supply automatic control system. Background technique [0002] The current secondary water supply methods mainly include: [0003] 1. Water tower: its disadvantages are large investment, large land occupation, easy pollution of water quality, and poor earthquake resistance; [0004] 2. High-level water tank: its disadvantages are that the water quality is easily polluted, the structural load of the building is increased, the management cost is high, and the shape of the building is affected; [0005] 3. Air-supplementing air pressure water supply device: its disadvantage is that the water supply pressure changes greatly, and the water quality is polluted by air-enhancing dust bacteria. After a period of use, under the influence of dirt on the water surface in the air pressure tank, dissolved air often occurs, which pollutes the w...

Problems solved by technology

[0003] 1. Water tower: its disadvantages are large investment, large land occupation, easy pollution of water quality, and poor earthquake resistance;

[0004] 2. High-level water tank: its disadvantages are that the water quality is easy to pollute, the structural load of the building is increased, the management cost is high, and the shape of the building is affected;

[0005] 3. Air-supplementing air pressure water supply device: its disadvantage is that the water supply pressure changes greatly, and the water quality is polluted by air-enhancing dust bacteria. After a period of use, under the influence of dirt on the water surface in the air pressure tank, dissolved air often occurs, which pollutes the water quality aggravated;

[0006] 4. Diaphragm type air pressure water supply equipment, its disadvantage is that the diaphragm is folded irregularly during use, the service life is limited, and the service life of the whole machine is relatively short
