Summary of the invention
The purpose of the present invention is to provide the bearing calibrations that a kind of washing machine loads fuzzy weighing, solve existing washing machine
Because of the problem of water level inaccuracy caused by engine conveyer belt aging.
In order to solve the above technical problems, the present invention is achieved by the following technical solutions:
The present invention is a kind of bearing calibration of the fuzzy weighing of washing machine load, comprising the following steps:
Step 1, measurement washing machine load acquisition value are i, and store；
Step 2 compares the size for loading acquisition value i and default unloaded preset value A, when load acquisition value i is pre- greater than unloaded
If when value A, carrying out step 3, otherwise, step 4 is carried out；
Step 3 calls coefficient N according to load acquisition value i, calculates the gear D of water, gear D includes 1,2,3 ..., 8 grades
Water level, C=(A-i) mod N, when C is 0, gear D takes 4 grades of water levels；When C is 1, gear D takes 5 grades of water levels；When C is 2,
Gear D takes 6 grades of water levels；When C is 3, gear D takes 7 grades of water levels；When C is 4, gear D takes 8 grades of water levels；
Step 4 calls coefficient N according to load acquisition value i, calculates the gear D of water, gear D includes 1,2,3 ..., 8 grades
Water level, C=(i-A) mod N, when C is 0, gear D takes 4 grades of water levels；When C is more than or equal to 1, gear D takes 3 grades of water levels.
Preferably, the zero load preset value A and load acquisition value i is to the umber of pulse of motor-induced electromotive force
Number statistical value.
Preferably, the coefficient N in the step 3 and step 4 is measurement coefficient, and the coefficient N is conveyer belt in 5-10
In the case where the degree of wear, the median of the pulse number of motor-induced electromotive force.
The invention has the following advantages:
The present invention carries out ambiguity correction to washing machine loading condition by the induced electromotive force pulse number of detection motor, leads to
Default measurement parameter control water level of washing machine is crossed, effectively prevent washing machine because water level is not caused by the aging of engine conveyer belt
Accurate problem.
Certainly, it implements any of the products of the present invention and does not necessarily require achieving all the advantages described above at the same time.
