Abstract
The invention relates to a central control unit of a central PLC (programmable logic controller) controlled tap water supply system. The central control unit is composed of an industrial personal computer 1, configuration software 2, a PLC 3 and a frequency converter 4. The central control unit has the advantages that water supply capacity is enlarged, a water source is added, and the water source and reservoirs are controlled concentratedly.
Description
technical field
The present invention relates to the central control equipment of the tap water supply system that a kind of central PLC controls.
Background technology
Along with the development of small towns, county's economic construction, the further expansion of city size, the existing well of part water factory and high-level reservoir can not meet the growing demand of people's lives, need expand water supply capacity, newly-increased water head site, needs to carry out centralized control to water head site and cistern simultaneously.
summary of the invention
The central control equipment of the tap water supply system that the object of the present invention is to provide a kind of central PLC to control, is intended to expand water supply capacity, and newly-increased water head site, carries out centralized control to water head site and cistern simultaneously.For achieving the above object, the technical solution used in the present invention is
:the present invention relates to the central control equipment of the central control equipment of the tap water supply system that a kind of central PLC controls
,be made up of industrial computer 1, configuration software 2, PLC 3, frequency converter 4, it is characterized in that the central control equipment of the central control equipment of the tap water supply system that described a kind of central PLC controls
'spLC is as central control equipment, and the information such as the instruction assigned according to industrial computer 1 and the site pressure that detects, calculates the rotary speed instruction of secondary pipe network water supply frequency converter 4, by the rotating speed of Analog control frequency converter to obtain the constant pressure of water supply network.
advantage of the present invention:
Expand water supply capacity, newly-increased water head site, carries out centralized control to water head site and cistern simultaneously.
embodiment explanation
fig. 1 is system composition schematic diagram:
1-industrial computer 2-configuration software 3-PLC 4-frequency converter.
tell about below in conjunction with Fig. 1the central control equipment of the tap water supply system that a kind of central PLC controls
principle of work:
The present invention relates to the central control equipment of the central control equipment of the tap water supply system that a kind of central PLC controls
,be made up of industrial computer 1, configuration software 2, PLC 3, frequency converter 4, it is characterized in that the central control equipment of the central control equipment of the tap water supply system that described a kind of central PLC controls
'spLC is as central control equipment, and the information such as the instruction assigned according to industrial computer 1 and the site pressure that detects, calculates the rotary speed instruction of secondary pipe network water supply frequency converter 4, by the rotating speed of Analog control frequency converter to obtain the constant pressure of water supply network.The existing Frequency Converter Control of water factory four 55KW water pumps, realize secondary booster to supply water, the constant pressure water supply method of four water pumps is dragged with a frequency converter, after hydraulic pressure is lower than setting lower limit a period of time, the water pump of current for frequency converter dragging is switched to power frequency power supply state, this water pump operates at full speed, and frequency converter is switched to next water pump, after hydraulic pressure is higher than capping certain hour, frequency converter is switched to from the water pump of current control the water pump that an other power frequency powers automatically, and original the be with water pump of frequency converter quits work.The water pump full-speed operation that all power frequencies are powered; PLC calculates the quantity of supply well according to cistern water level signal, and according to the length of each well-water supplies time, calculates which pump and preferentially start water supply; which pump is preferentially shut down, and is sent to each well frequency converter by communication mode.And obtain each well converter parameter, as parameters such as voltage, electric current, rotating speed, faults by communication mode.
