Abstract
A fuzzy control method for washing machine features that the memory and learning function and power loss memory function are set up. A detector measures the physical parameters of motor for empty cylinder and judges if the physical parameters are up to standard. If their differences is out of the allowable value, this learning is failed and next learning begins. If this learning is a success, the correspondent data is used as control value according to the fuzzy control rule. Said power loss memory function is that it can record the work state on lossing power and then restore to work in the recorded state when the power is restored.
Description
The present invention relates to the control method of Fuzzy Control of Washing Machines method and power-failure memory.
The fuzzy control washing machine of Tui Chuing is various in style in the market, but because the fuzzy control device and the method that are adopted do not possess self-adjustment capability, exists following deficiency:
1. in process of production, because human errors such as the discreteness of mechanical parts such as motor, belt, belt pulley, wash bucket and installation, cause the fuzzy judgement value of washing machine and actual needs to have big gap, thereby judge that effect can't guarantee that designing requirement and uniformity are poor.Mechanical system is debugged in general employing repeatedly as remedial measure, the control effect is reached within the error range of permission, this means of remedying are loaded down with trivial details processes, it will seriously reduce labor productivity, increase production cost, washing machine is through after a while use on the other hand, and the state of mechanical system will change again, and this variation makes the washing machine fuzzy control judge deleterious.
Another critical defect that exists in the existing washing machine fuzzy control technology is exactly not possess power down protection; be that washing machine is in washing process; if have a power failure; duty then of living in will be lost; both made incoming call again; washing machine can not start work automatically, promptly can not continue to finish remaining program, and this defective is brought very big inconvenience to the user.
Purpose of the present invention is provided with the mnemonic learning function exactly in the washing machine Fuzzy control system, measure the damping original state of washing machine transmission system formation and select suitable washing procedure and parameter by testing circuit, guarantee the accuracy of necessary control amount in the washing machine fuzzy control with this.
A further object of the present invention is provided with the power-failure memory function exactly and guarantees the front and back that have a power failure with this, and the laundry function postpones and finishes its various washing procedures.
Control method of the present invention:
A. utilize testing circuit to measure the electricity physical quantity of motor under the empty tubbiness attitude;
B. judge that institute's physical quantity of surveying is whether in acceptability limit and make following selection: if one is overproof, then learn to fail, restart; If its two learning success is then determined the value of corresponding data as controlled quentity controlled variable by the fuzzy control rule between controlled quentity controlled variable of having set up and the above-mentioned physical quantity.
Above-mentioned controlling party ratio juris is to utilize testing circuit to measure the damping original state of washing machine transmission system or chain formation, select suitable fuzzy control critical parameter as benchmark in view of the above, the influence that the variation of state produces measurement in the discreteness of correction mechanical system and the use, thus the accuracy that guarantees the washing machine fuzzy control is also remembered.
Power-failure memory control method of the present invention is the monitoring power supply, generally monitors supply voltage and gets final product, and when power-down conditions takes place work at present state and data instant is kept in the memory.
The power-failure memory function is set has realized that effectively if having a power failure, controller will be preserved the washing machine current working state automatically, can continue to finish remaining program behind the incoming call in the washing course of work.
Fig. 1 is a learning functionality logic schematic diagram of the present invention;
Fig. 2 is cloth amount membership function figure;
Fig. 3 is learning process figure of the present invention;
Fig. 4 is the power-failure memory logic chart.
The invention will be described in further detail below in conjunction with accompanying drawing.
Embodiment
Select built-in E for use
2Little process chip of PROM (being called for short MCU), this is the hardware condition that learning and memory function and power-failure memory function are set, and adopts the built-in E of MCU
2PROM realizes Fuzzy Control of Washing Machines as mnemon.
The basis that the washing machine water level is judged is the accurate detection to the cloth amount, and the cloth amount detects by motor inverse electromotive force number of pulses---umber of pulse realizes.
A large amount of test datas show, under certain line voltage, washing machine is in different original states, when promptly empty bucket is anhydrous, umber of pulse shows as different non-linear relations with the relation of washing cloth amount, and the identical in other words pairing umber of pulse of cloth amount is along with the variation of the original state of washing machine changes.There is E in the relation of cloth amount and umber of pulse under the different original states with the form of form
2Among the PROM,, select corresponding data sets, and deposit separately by measuring the original state (being the learning process of washing machine) of washing machine, with this as the standard of washing machine fuzzy controller, referring to Fig. 1 to the obfuscation of cloth amount.
Fig. 2 provides the mnemonic learning flow chart of washing machine, it comprises mnemonic learning first in the production process and the mnemonic learning in user's use, an additional step as the mnemonic learning function, be provided with study Failure Alarm program, when learning umber of pulse (original state) when exceeding scope of design, produce buzzing warning reminding reviewer or user, this whole machine installation is defective or need repairing, and failure cause generally is that mechanical damping system is too big or too little.
Power-failure memory is to utilize E
2The duty of PROM memory washing machine realizes that the variation for fear of power down front and back work state of washing machine guarantees that simultaneously mnemon has sufficiently long service time, and the concrete technology contents of power-failure memory is the monitoring supply voltage; When power down takes place, work at present state and data instant are saved in E
2Among the PROM, control flow can be referring to Fig. 4.The content of power-failure memory mainly comprises the duty sign, program process time quantum, video data unit, key-press status sign, test sign etc.
Claims (3)
1. fuzzy control method for washer, it comprises following process:
A. utilize testing circuit to measure the electricity physical quantity of motor under the empty tubbiness attitude;
B. judge that above-mentioned physical quantity is whether in acceptability limit and make following selection: if one is overproof, then study failure restarts; If its two learning success is then determined the value of corresponding data as control by the fuzzy control rule between controlled quentity controlled variable of having set up and the above-mentioned physics.
2. control method for washing machine according to claim 1, cloth consumption testing circuit are measured motor inverse electromotive force number of pulses under the empty tubbiness attitude, and by the cloth amount of having set up---pulse data membership function table is determined the value of corresponding data as controlled quentity controlled variable.
3. fuzzy control method for washer, it comprises following process: the monitoring power supply is kept at work at present state and data instant in the storage when power-down conditions takes place.
