Description
Technical field
The utility model relates to a kind of water pump controller.
Background technique
Along with making rapid progress of science and technology, the fast development of sensor industry, adds pressure transducer in water pump controller, rakes in market accreditation with the advantage of its uniqueness.But there is a variety of Water pump pressure controller on the market now, but all also have deficiency from function and reliability.Pump working state can not be shown in real time, and Stress control inaccuracy.
Summary of the invention
The utility model object is to provide a kind of control accurately, in real time to show pump working state, the water pump controller of automatically controlled water pump start and stop for the defect of prior art.
The utility model for achieving the above object, adopts following technological scheme:
A kind of water pump controller, is characterized in that: it comprises pressure detection circuit, input device, single-chip microcomputer, relay and display device;
Described pressure checking device for detecting the pressure in water pump pipeline, and sends the pressure signal detected to single-chip microcomputer;
The force value that described single-chip microcomputer is used for pressure signal and the setting transmitted by pressure checking device compares, and exports control signal control relay break-make, and pressure signal, setup pressure value and relay status is exported to display device display;
Described input device is used for the force value to single-chip microcomputer input setting;
The control signal break-make that described relay exports according to single-chip microcomputer, controls the start and stop of water pump;
Described display device is for showing pressure signal, setup pressure value and relay status.
It is further characterized in that: described pressure checking device comprises pressure transducer, amplification circuit and analog-to-digital conversion module; The pressure signal that detects after amplification circuit amplifies, then is converted to digital signal through analog-to-digital conversion module and is sent to described single-chip microcomputer by described pressure transducer.
Preferred: described pressure transducer is ceramic pressure sensor.

Accompanying drawing explanation
Fig. 1 is the utility model structural representation.
Embodiment
A water pump controller as shown in Figure 1, comprises pressure detection circuit, input device, single-chip microcomputer, relay and display device.
Described pressure checking device for detecting the pressure in water pump pipeline, and sends the pressure signal detected to single-chip microcomputer; Described pressure checking device comprises ceramic pressure sensor, amplification circuit and analog-to-digital conversion module; The pressure signal that detects after amplification circuit amplifies, then is converted to digital signal through analog-to-digital conversion module and is sent to described single-chip microcomputer by described pressure transducer.
Described single-chip microcomputer is STM8S003F3P6 single-chip microcomputer, force value for the pressure signal that transmitted by pressure checking device and setting compares, export control signal control relay break-make, and pressure signal, setup pressure value and relay status are exported to display device display.
Described input device is+,-two buttons, for the force value to single-chip microcomputer input setting.
The control signal break-make that described relay exports according to single-chip microcomputer, controls the start and stop of water pump.
Described display device is digital display tube, for showing pressure signal, setup pressure value and relay status.
Specific works state of the present utility model:
1, after controller powers on, digital display tube is lighted, and indicates for system power state.If hydraulic pressure was in low pressure or pressure-less state in 5 seconds in pipeline, automatic evaluation is then exsiccosis by controller, now water pump stall (relay disconnection).
2, when controller is started working, digital display tube shows---, enter running state after 2 seconds, digital display tube display real-time pressure, unit is bar, 2 Digital sum display tube displays, such as 1.0bar, is arranged when can carry out water pump start and stop pressure when running state.Press input key, enter the adjustment of the hydraulic pressure upper limit after digital display tube display H and arrange, pass through+,-button carries out pressure setting.
3, after ceramic pressure sensor detects pressure, single-chip microcomputer judges, when pipeline is not in exsiccosis but when hydraulic pressure, open relay lower than setting value, connects water pump operation work.After single-chip microcomputer confirms water pressure condition, if current water pipe is in exsiccosis, block system relay, protection water pump, shows hydraulic pressure number simultaneously.
