Specifically, calculate the motor transient state angle of flow when uniform rotation, according to the motor transient state angle of flow when uniform rotation and the characteristic curve of motor power signal, calculate the transient power that motor consumes when uniform rotation.
Step 202, even acceleration rotates setting motor, and the speed in even acceleration rotation process is less than resonance point, calculates the transient power that motor consumes when even acceleration rotates during the even acceleration of motor is climbed.
Specifically, calculate the motor transient state angle of flow when even acceleration rotates, according to motor at the even transient state angle of flow accelerated when rotating and the characteristic curve of motor power signal, calculate the transient power that motor consumes when even acceleration rotates.
Step 203, the transient power consumed when the transient power consumed when even acceleration rotates by motor and motor are in uniform rotation does difference operation, obtains transient state difference power.
Step 204, is integrated summation, obtains motor to medicated clothing work done transient state difference power.
Follow-up, according to size and the corresponding relation of clothes weight of merit, the clothes weight that motor is corresponding to medicated clothing work done can be found.
Above-described embodiment, calculate transient power and motor transient power of consumption when even acceleration rotates that motor consumes when uniform rotation respectively, the two does difference and obtains transient state difference power, motor is obtained to medicated clothing work done according to transient state difference power, thus eliminate the diversity of machine system to the impact produced of weighing, for example, it is possible to eliminate the weighting error that when cylinder rotates, inconsistent or cylinder damping frame the diversity etc. of bearing damp causes.
In order to reduce the impact of the aqueous weighing results of medicated clothing, before medicated clothing in washing machine is weighed by the present invention, medicated clothing can also be carried out processed, the principle schematic that processed and medicated clothing are weighed is shown in Figure 4, motor water desorption curve is shown in Figure 5, and processed specifically includes following steps:
Step 301, setting motor speed, to the first rotating speed A2, assesses the complete machine unbalanced state under the first rotating speed A2.
Step 302, if the complete machine unbalanced state under the first rotating speed A2 is less than the first preset value, setting motor speed is to the second rotating speed B2, and otherwise, keeping motor speed is the first rotating speed A2.So may insure that motor when the first rotating speed A2 climbs the second rotating speed B2, complete machine is in relative balance state.
Step 303, sets motor speed to the 3rd rotating speed C2, the complete machine unbalanced state under assessment the 3rd rotating speed C2.
Step 304, if the complete machine unbalanced state under the 3rd rotating speed C2 is less than the second preset value, setting motor speed is to the 4th rotating speed E2, and otherwise, keeping motor speed is the first rotating speed A2.So may insure that motor when the 3rd rotating speed C2 climbs the 4th rotating speed E2, complete machine is in relative balance state.
Step 305, weighs to medicated clothing between the 3rd rotating speed C2 and the 4th rotating speed E2.
Wherein, A2=C2 < E2 < B2, A2 represents the first rotating speed, and B2 represents the second rotating speed, and C2 represents the 3rd rotating speed, and E2 represents the 4th rotating speed.
