The application of water pump is more and more extensive, and the effect of water pump controller is more and more obvious, requires also more and more higher.
Traditional water pump controller mainly is divided into two kinds of float-ball type and mechanical types, float-ball type is that water level float is placed within the floating ball tank, settles respectively several ball floats contact of different heights, when water level arrives the ball float position of diverse location, triggering and conducting reaches the purpose of control water level with this.Its shortcoming is that inconvenience is installed, and control accuracy is not high, and produces easily misoperation, damages water pump.
The characteristics of mechanical type water level control: mechanical type is that the deformation by elastic element comes picked up signal, and the conducting contact reaches the purpose of control.Its shortcoming is that set point is fixed, and control accuracy is not high, and the life-span is low, uses for a long time unstable error large.
Simultaneously traditional water pump controller automatic control effect is bad, does not have intelligent control function, can't see in real time pressure condition, can't accomplish excessive low water level protection.
Summary of the invention
The purpose of this utility model is to solve above-mentioned realistic problem; aim to provide a kind of automatic controller for water pump of on-mechanical formula intelligence; integrated number shows that in real time pressure, control point regulates controlled, excessive low water level protection, delay voltage, and precision is high simultaneously, the life-span is long, shock resistance is better
For achieving the above object, the technological scheme taked of the utility model is:
A kind of automatic controller for water pump, comprise pressure transducer, control circuit, the signal output part of described pressure transducer is connected with the pressure signal input end of control circuit, described control circuit comprises for the control signal output terminal to controlled water pump output start stop signal, pressure signal and pre-set threshold value that described control circuit is relatively inputted by pressure transducer, when meeting when pre-conditioned, by control signal output terminal output start stop signal.
Described control circuit comprises amplification circuit, single-chip microcomputer, described pressure signal input end is the input end of described amplification circuit, described amplification circuit output end connects DI Digital Interface of processor of described single-chip microcomputer by A/D convertor circuit, another DI Digital Interface of the processor that described control signal output terminal is described single-chip microcomputer, this interface connects the relay that is used for controlling controlled pump power break-make.
As improvement, for the ease of man-machine interaction, described control circuit also comprises a digital pipe display circuit, the processor of the described single-chip microcomputer of input termination of described digital pipe display circuit, output termination nixie tube.Described single-chip microcomputer is exported instant force value by digital pipe display circuit to nixie tube after receiving the pressure signal of pressure transducer.Current pressure can be shown intuitively by this number display circuit, the pressure of operating point can be set by nixie tube again simultaneously.
As again step improvement, in order to realize artificial setting and the modification to pre-set threshold value, described controller also includes button, and described button links a DI Digital Interface of single-chip microcomputer, comes the digital signal threshold values of processing single chip inside by the flat signal of height that obtains.Described single-chip microcomputer response key operation, and to nixie tube output key operation indicating and/or key operation result.
The utility model utilizes the pressure transducer sense cell along with the change of hydraulic pressure diminishes greatly, and the analogue signal of output is linear output, enters single-chip microcomputer through amplification and AD conversion.Because the simulation model is converted to digital signal, because can realize high-resolution shows, highi degree of accuracy control, the pressure of mensuration in advance numeral are set, and in real time control reaches Microsecond grade, machinery-free contact and friction, reach unlimited working life, in real time control response is fast, comes the break-make of control relay with control circuit, output power is large, directly controls the stop and start of water pump.Controller directly by showing the current pressure value, can directly be adjusted upper and lower by button force value is set.
