Abstract
The invention relates to a central control device of a water well PLC controlled taper water supply system. The central control device consists of an industrial personal computer 1, configuration software 2, a central PLC 3, a water well PLC 4 and a frequency converter 5. The central control device has the advantages of achieving PLC centralized control respectively conducted on a water source and an impounding reservoir respectively.
Description
technical field
The present invention relates to the central control equipment of the tap water supply system that a kind of well 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 reservoir 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 well PLC to control, is intended to carry out PLC centralized Control respectively to water head site and reservoir.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 tap water supply system that a kind of well PLC controls
,be made up of Industrial Personal Computer (IPC) 1, configuration software 2, central PLC 3, well PLC 4, frequency converter 5, it is characterized in that the central control equipment of the tap water supply system that described a kind of well PLC controls
'scentral authorities' PLC 3 and well PLC 4 are as central control equipment, the information such as the instruction assigned according to Industrial Personal Computer (IPC) 1 and the site pressure that detects, calculate the rotary speed instruction of secondary pipe network water supply frequency converter 5, by the rotating speed of Analog control frequency converter to obtain the constant pressure of water supply network.
advantage of the present invention:
Achieve and respectively PLC centralized Control is carried out to water head site and reservoir.
detailed description of the invention explanation
fig. 1 is system composition schematic diagram:
1-Industrial Personal Computer (IPC) 2-configuration software 3-central authorities PLC 4-well PLC 5-frequency converter.
tell about below in conjunction with Fig. 1the central control equipment of the tap water supply system that a kind of well PLC controls
operating principle:
The present invention relates to the central control equipment of the central control equipment of the tap water supply system that a kind of well PLC controls
,be made up of Industrial Personal Computer (IPC) 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 well PLC controls
'spLC is as central control equipment, and the information such as the instruction assigned according to Industrial Personal Computer (IPC) 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 water pumps, realize secondary booster and supply water.The constant pressure water supply 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 to power OFF state, this water pump works 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.All power frequencies water pump of powering is power supply at full speed, and frequency converter drags the rotary speed instruction that a water pump exports according to PLC and realizes constant pressure supplying water.PLC calculates the quantity of water supply well according to reservoir water level signal; and according to the length of each well-water supplies time; calculate which pump and preferentially start water supply; which pump is preferentially shut down; each well PLC substation is sent to by communication mode; and by communication mode obtain each well PLC transmit return parameter, as parameters such as voltage, electric current, rotating speed, faults.
