Specific embodiment
Below in conjunction with the accompanying drawing in the embodiment of the present invention, the technical scheme in the embodiment of the present invention is carried out clear, complete
Site preparation is described, it is clear that described embodiment is only a part of embodiment of the invention, rather than whole embodiments.It is based on
Embodiment in the present invention, it is every other that those of ordinary skill in the art are obtained under the premise of creative work is not made
Embodiment, belongs to the scope of protection of the invention.
Refer to Fig. 1~2, in the embodiment of the present invention, a kind of washing machine water amount control system, including console controller, from
Machine controller, main frame magnetic valve and slave magnetic valve, main frame magnetic valve are used to control washing machine to discharge water, and slave magnetic valve is used to control
Washing machine inflow processed, is preset by key-press module to console controller and from machine controller, and host sensor is measured currently
The corresponding magnitude of voltage of water level, then compare with setting value by sending into console controller after A/D modular converter analog-to-digital conversions, main frame control
Device processed passes through control main frame electromagnetism valve regulation washing machine liquid level；Console controller is set by communication interface to being transmitted from machine controller
Definite value, from machine controller by controlling slave electromagnetism valve regulating flow；After slave sensor collection washing machine inflow amount data, according to
It is secondary to be sent to console controller through A/D converter, from machine controller and communication interface.
The console controller knows liquid fluctuating situation in washing machine by host sensor, if liquid fluctuating is more than pre-
If value, then illustrate that washing machine internal amount of liquid is optimum state, between the clothing and clothing of washing machine internal, clothing and liquid it
Between friction level also be optimum state, now control main frame magnetic valve and slave magnetic valve are remained off；If liquid surface wave
It is dynamic to be less than preset value, then illustrate that washing machine internal amount of liquid is more, because more liquid, when washing machine works, its liquid level
Could held stationary, now control main frame magnetic valve open and externally discharge water, during discharging water, the host sensor moment detection ought
Preceding water level conditions, until setting value represents that liquid fluctuating, more than preset value, closes main frame magnetic valve；If host sensor cannot be examined
Liquid level is measured, represents that liquid is very little in now washing machine, now control slave magnetic valve to open, control washing machine inflow, water inlet
During, slave sensor calculates the flow of water inlet, while host sensor moment detection current level situation, until setting value
Represent that liquid fluctuating is more than preset value, close slave magnetic valve.
The A/D modular converters and A/D converter use chip IC L7135.The console controller and slave are controlled
Device uses single-chip microcomputer pic16f917.The communication interface uses RS485 communication interfaces.
Ultrasonic sensor is a kind of Miniature Sensor, although its small volume, is had with other larger sensors
Some functions, Color influences that are easy to install and not receiving testee, have many ad hoc functions, such as：Mended with temperature
Repay function, analog quantity or output switch parameter etc. may be selected；Its supply voltage is 10~30V, and measurement range is 30mm~300mm,

It is linear pattern and perpendicular type.Sensing bore is 18mm.
The condition that ultrasonic sensor has meets requirement of the level error no more than ± 0.3cm that design is wanted,
And solve and inconvenient problem is installed, so the design host sensor have selected high precision, small ultrasonic wave is passed
Sensor S18UUA.
The specific principle of ultrasonic sensor detection liquid level is as follows in the present invention：Worked ultrasonic sensor is needed
When, ultrasonic sensor constantly sends ultrasonic signal and receives the ultrasonic signal of return, and the return signal of reception passes through A/D
Modular converter feeds back to console controller, the time difference that console controller feeds back according to unlike signal, draws a width dynamic
Liquid level figure, in 5s, the mean range of this dynamic Liquid Surface figure and preset value are contrasted, so as to judge liquid fluctuating
Concrete condition.
Using 4 half double integration A/D converter ICL7135, it has high precision, the output of polarity automatic conversion, automatic school
0th, single power supply work, dynamic binary-coded decimal output.Because the quadratic integral time of double integrator method is long, so A/D is changed
Speed is slow, usually (3~10) it is secondary/s, additionally, being zero to the interference signal integration of mechanical periodicity, interference free performance also compares
Good, in the case of equal accuracy, ICL7135 prices are less than successive approximation type a/d converter, thus not high to rate request
Occasion, be more readily adapted to this kind of A/D converter.
