Description
Technical field
The utility model relates to supply equipment technical field, is specifically related to a kind of constant-pressure variable supply equipment with remote monitoring function.
Background technology
In the production, living water use process of all kinds of building daily life water, all kinds of industrial and mining enterprises, when often occurring that water supply volume increases, the phenomenon that hydraulic pressure reduces, although the supply equipment kind used in existing regional water supply is also a lot, but the hydraulic pressure of existing supply equipment is negative correlation with the quantity of use water, when using water number amount various flow large, hydraulic pressure can diminish accordingly., when, just often there is the phenomenon that high-rise buildings hydraulic pressure is very low in the community user that such as floor is higher the water use peak time period in the evening at noon, time serious, the very little impact of water yield uses water normally, and few once water supply volume, then hydraulic pressure can increase suddenly, causes pipe network to damage sometimes.
Utility model content
The technical problems to be solved in the utility model: supply water even if existing part supply equipment cannot realize constant-pressure variable or achieve constant-pressure variable water supply but device structure complexity, pressure of supply water is still stable not;
Most supply equipment all needs field control, cannot realize remote monitoring.
In order to solve above technical problem, the technical solution of the utility model is as follows: the constant-pressure variable supply equipment with remote monitoring function, it is characterized in that, comprise n water pump, a n frequency converter, the first pressure sensor, pressure compensation tank, the second pressure sensor, controller, the first wireless communication module, the second wireless communication module, remote controller, touch-screen;
The water inlet of n water pump connects the inlet channel of supply equipment, and the delivery port of n water pump connects the outlet conduit of supply equipment;
The outlet conduit of supply equipment is provided with the first pressure sensor, pressure compensation tank, the second pressure sensor, pressure compensation tank is between the first pressure sensor and the second pressure sensor;
First pressure sensor, the signal output part of the second pressure sensor are connected with the I/O port of controller;
The I/O port of controller is connected with the Stress control end of pressure compensation tank;
Controller passes through the rotating speed of i-th Frequency Converter Control, i-th water pump, 1≤i≤n;
Controller is electrically connected with the first wireless communication module, and remote controller is electrically connected with the second wireless communication module, and controller is communicated with remote controller by the first wireless communication module, the second wireless communication module;
Touch-screen is electrically connected with remote controller.
The technical scheme be more preferably, described controller adopts S7-200PLC to realize.
The technical scheme be more preferably, described water delivery side of pump is provided with flow transmitter, and the signal of flow transmitter collection is input to controller.
Compared with prior art, the beneficial effects of the utility model: the constant-pressure variable supply equipment with remote monitoring function of the present utility model can adjust the water yield automatically according to the demand size of water supply volume, assure feed water constant pressure simultaneously, and structure is simple, pressure of supply water is stablized, and intelligence degree is high; Each Frequency Converter Control water pump, instead of the Push And Release of simple control water pump, so water yield is accurate; Outlet conduit be provided with two pressure sensors and can be easy to judge whether pressure compensation tank normally works by the difference of two pressure sensors.Achieve the monitoring of far-end simultaneously, can be easy to see on-the-spot data cases by the touch-screen of far-end.
Accompanying drawing explanation
Fig. 1 is the utility model principle schematic;
Detailed description of the invention
Below in conjunction with accompanying drawing, the utility model is described in further detail.
There is the constant-pressure variable supply equipment of remote monitoring function, comprise 3 water pumps, 3 frequency converters, the first pressure sensor, pressure compensation tank, the second pressure sensor, controller, the first wireless communication module, the second wireless communication module, remote controller, touch-screens; The water inlet of 3 water pumps connects the inlet channel of supply equipment, and the delivery port of 3 water pumps connects the outlet conduit of supply equipment; The outlet conduit of supply equipment is provided with the first pressure sensor, pressure compensation tank, the second pressure sensor, pressure compensation tank is between the first pressure sensor and the second pressure sensor; First pressure sensor, the signal output part of the second pressure sensor are connected with the I/O port of controller; The I/O port of controller is connected with the Stress control end of pressure compensation tank; Controller passes through the rotating speed of i-th Frequency Converter Control, i-th water pump, 1≤i≤3; Controller is electrically connected with the first wireless communication module, and remote controller is electrically connected with the second wireless communication module, and controller is communicated with remote controller by the first wireless communication module, the second wireless communication module; Touch-screen is electrically connected with remote controller.
Wherein, controller adopts S7-200PLC to realize, and remote controller adopts MSP430 single-chip microcomputer; Water delivery side of pump is provided with flow transmitter, and the signal of flow transmitter collection is input to controller.
Utility model works principle: know current normal discharge pressure according to the first pressure sensor, again according to target discharge pressure, thus obtain the pressure size of pressure compensation tank needs compensation, controller controlled pressure compensating tank carries out pressure compensation, the second pressure sensor can real-time judge pressure compensation tank compensate pressure whether correct; Controller, by each water pump of each Frequency Converter Control, really achieves the control of accurate water yield, instead of traditional controller just controls the Push And Release of water pump.
The data of spot sensor collection are transferred to remote controller by wireless module, are shown by touch-screen, can readily appreciate that on-the-spot situation, also can by the control data at touch-screen change scene.
