Line is able to detect that corresponding color value when the light is irradiated to color identification module 12, certain color detected
The actual color value that value can be sent out with light emitting module 11, certainly since the consistency of device has differences, what this was detected
Color value can also be the color value with certain deviation.
With reference to shown in Fig. 2, the embodiment of the present invention provides a kind of anti-clothes washing control method that fades, and is applied to above-mentioned
Washing machine specifically comprises the following steps：
101, prevent fading clothes washing control device to light emitting module input test drive signal, and adjusted in predetermined interval
The duty ratio of PWM in whole Test driver signal, Test driver signal is for driving light emitting module to shine.
It is exemplary, the duty ratio of PWM can be adjusted from 10% to 99% according to fixed step size, can make to shine in this way
The light intensity that module is sent out gradually enhances.
102, the anti-clothes washing control device that fades obtains at least one test color value of color identification module acquisition,
The duty ratio of middle test color value and PWM correspond.
Wherein, before washing machine opens washing procedure, the also non-water filling of washing machine, then the collected face of color identification module
Color value collected color value when shining directly into color identification module for the light that light emitting module is sent out.The wherein color value
Can be the sum of rgb value SUM.
103, the anti-clothes washing control device that fades is determined for compliance with the mesh of predetermined condition at least one test color value
Color value is marked, and calibration drive signal is generated according to the corresponding PWM duty cycle of target color values.
Wherein, which can be one all tested in color value with standard color value deviation ratio minimum,
The color value deviation of the color value that color identification module measures and the light that light emitting module is sent out can be made minimum in this way.Such as
The target color values are denoted as the sum of rgb value SUMst.Standard color value can be one group of numerical value of prior acquisition, wherein can incite somebody to action
Each standard color value and the duty ratio of PWM are established mapping relations and are stored in a mapping table, when device collects at least one
After a test color value, is tabled look-up according to the duty ratio of the corresponding PWM of test color value and obtain the corresponding standard face of test color value
Color value；Then true with the test color value of the deviation ratio minimum of corresponding standard color value by least one test color value
It is set to target color values.Deviation ratio wherein above-mentioned is (| test color value-standard color value |)/standard color value.
104, prevent fading clothes washing control device to light emitting module input calibration drive signal, to drive light emitting module to send out
Light, and control washing machine and open dynamic washing procedure.
105, the anti-clothes washing control device that fades obtains the detection color of color identification module acquisition in washing process
Value, when the difference for detecting color value and target color values is less than or equal to predetermined color threshold value, control washing machine, which continues to execute, to be washed
Wash program.
Wherein, after washing machine opens washing procedure, washing machine water filling, then the collected color value of color identification module
The light sent out for light emitting module is through collected color value when being irradiated to color identification module after slurry.In the mistake
The sum of collected color value rgb value is denoted as SUMte in journey, then the bigger expression clothes of SUMst-SUMte fades more serious.Work as inspection
It measures
When SUMst-SUMte≤color threshold R, R indicates the Cheng Du that tolerance clothes has faded, and can continue to wash, no
Then follow the steps 106.
106, when the difference for detecting color value and target color values is more than predetermined color threshold value, anti-clothes washing control of fading
Device control washing machine processed starts care program, new execution washing procedure of laying equal stress on of intaking after washing machine drainage.
In the above scheme, before washing machine executes washing procedure, the anti-clothes washing control device that fades is to luminous mould
Block input test drive signal, and in predetermined interval adjust Test driver signal in PWM duty ratio, then obtain color know
The duty ratio one-to-one correspondence test color value with PWM of other module acquisition；And it is determined for compliance at least one test color value
The target color values of predetermined condition, and calibration drive signal is generated according to the corresponding PWM duty cycle of target color values；It realizes pair
Then the correction of light emitting module and the consistency of color identification module drives light emitting module to shine by calibrating drive signal, and
The detection color value that the acquisition of color identification module is obtained after control washing machine is opened and moves washing procedure, when detection color value and mesh
Mark color value difference be less than or equal to predetermined color threshold value when, control washing machine continue to execute washing procedure, the process reduce or
The influence that light emitting module identifies color with the consistency of color identification module accuracy is avoided, washing machine is improved and prevents fading
The accuracy of clothes washing control.
In addition, further including before step 101 to reduce the program before washing procedure is opened：
S1, the anti-clothes washing control device that fades input predetermined drive signal to drive light emitting module to send out to light emitting module
Light, predetermined drive signal include the PWM of predetermined duty ratio.
The illustrative predetermined drive signal can be factory default or being stored after last time washing according to mesh
Mark the calibration drive signal that the corresponding PWM duty cycle of color value generates.
S2, the anti-clothes washing control device that fades obtain the predetermined color value of color identification module acquisition, work as predetermined color
When value meets predetermined condition, control washing machine, which is opened, moves washing procedure.Otherwise, step 101 is executed.
If drive signal predetermined in this way meets above-mentioned predetermined condition, illustrate that the predetermined drive signal can make color
The color value deviation for the light that the color value and light emitting module that identification module measures are sent out is smaller, meets the requirement of detection, will not
The accuracy of the anti-clothes washing control of fading of washing machine is influenced, therefore controls washing machine and directly opens washing procedure, so as to
Save processes of the above-mentioned steps 101-104 to light emitting module and the correction of the consistency of color identification module.
