Abstract
The invention discloses the compensation method of a kind of toilet stepping motor step pitch, washing time according to presetting carries out interval compensates, namely to frequency setting predetermined interval number of times that step pitch compensates, is extended in the useful life of motor: the number of times in motor useful life itself is multiplied by default washing time interval.Avoiding motor carrying out occurring stuck state and producing a large amount of heat when step pitch compensates, avoiding burning out motor, extend motor useful life.
Description
Technical field
The invention belongs to electronic technology field, particularly a kind of toilet stepping motor step pitch compensation method.
Background technology
Current bathroom market, full-automatic flushing, oven dry hip toilet are just more and more used more widely, user is sitting on toilet not only easy, comfortable, can also enjoy comprehensive put in place flush the toilet, wash hip, dry hip services, but the extension and contraction control of washing the cleaning machine that hip use in prior art is by step motor control.But due to stepping motor teeth groove situation, core material, the factor of boundary condition, add the fixing of stepping motor bearing internal hardware structure, certain friction can be there is in installation, what pulse signal can be caused to control departs from expection, cause the trickle gap of motor step distance thus, and after the trickle gap of motor step distance runs up to certain amount, motor can be made to control inaccuracy to cleaning machine telescopic location, cleaning machine is made to produce very large skew, the abnormal ejection of water, so can not accurately be with by consumer positioning anus one, causing can not thorough wash clean, cause awkward and inconvenient greatly.Therefore need to compensate the step pitch of stepping motor, to calibrate the control of motor to cleaning machine.
The step pitch that motor with friction mechanism can realize motor compensates, the friction mechanism of motor has its fixing useful life, step pitch compensates often carries out once, namely realize motor torque by friction mechanism to export once, namely prior art is the mode that an employing samsara compensates once to the compensation of stepping motor step pitch, namely to motor each time moment export the trickle step pitch produced and compensate, because friction mechanism produces the mechanism to electric motor protecting, predict in advance often in useful life of friction mechanism, or 1,000 times, 2000 times, if and often use the compensation way once namely compensated once that motor can be made to produce a large amount of heat, grievous injury motor, motor is caused to be scrapped in advance, decrease motor access times.
Summary of the invention
In order to overcome the defect that above-mentioned prior art exists, the invention provides the compensation method of a kind of toilet stepping motor step pitch, extending motor useful life.
To achieve these goals, technical scheme of the present invention is as follows:
The compensation method of a kind of toilet stepping motor step pitch, comprises the steps:
After a, user seat, stepping motor is in readiness, and delay N performs flush command after second, and N is natural number;
After b, execution flush command, flushing total degree is judged, rinse total degree and be less than preset times M, then motor is return step number and is equaled current flushing total degree, rinse total degree be more than or equal to preset times M, then motor return step number equal current flushing total degree add step pitch compensate step number;
After c, motor step distance is compensated, flushing total degree is reset and then performs the self-cleaning order of shower nozzle;
After d, the self-cleaning order of execution shower nozzle, perform shower nozzle and return order.
As preferably, N of the present invention is 2 ~ 4.
As preferably, preset times M of the present invention is 1 ~ 200 time.
The invention has the beneficial effects as follows, to frequency setting predetermined interval number of times that step pitch compensates, avoiding motor carrying out occurring stuck state and producing a large amount of heat when step pitch compensates, avoiding burning out motor, extend motor useful life.
Accompanying drawing explanation
Fig. 1 is schematic flow sheet of the present invention.
Embodiment
In order to make creation characteristic of the present invention, technological means and reach object be easy to understand understand, set forth the present invention further below in conjunction with specific embodiment.
Referring to Fig. 1, the compensation method of a kind of toilet stepping motor step pitch, time of delay in step S22 is 3 seconds, in step S24, preset times is 100, first, and motor normal power-up, after seat until user, stepping motor is in readiness S21, judge last washing time apart from whether be greater than present interval time or etc. delay 3 seconds S22, perform flush command S23.Often perform once flushing order, then carry out the stored count of once flushing number of times.Add up current flushing total degree after this time rinsing and whether be less than preset times 100 S24, if be less than, then make motor return step number for current added up flushing total degree S25; If be not less than, then made motor return step number and equal current added up flushing total degree and add step pitch offset value S26.Motor step
After being compensated, rinsing total degree and reset S28.Perform shower nozzle self-cleaning order S29 again, return shower nozzle S30 after self-cleaning, motor step terminates apart from compensation work.
More than show and describe general principle of the present invention, principal character and advantage of the present invention.The technical staff of the industry should understand; the present invention is not restricted to the described embodiments; what describe in above-described embodiment and specification just illustrates principle of the present invention; the present invention also has various changes and modifications without departing from the spirit and scope of the present invention, and these changes and improvements all fall in the claimed scope of the invention.Application claims protection range is defined by appending claims and equivalent thereof.
Claims (3)
1. a toilet stepping motor step pitch compensation method, is characterized in that, comprise the steps:
After a, user seat, stepping motor is in readiness, and delay N performs flush command after second, and N is natural number;
After b, execution flush command, flushing total degree is judged, rinse total degree and be less than preset times M, then motor is return step number and is equaled current flushing total degree, rinse total degree be more than or equal to preset times M, then motor return step number equal current flushing total degree add step pitch compensate step number;
After c, motor step distance is compensated, flushing total degree is reset and then performs the self-cleaning order of shower nozzle;
After d, the self-cleaning order of execution shower nozzle, perform shower nozzle and return order.
2. according to the method described in claim 1, it is characterized in that, described N is 2 ~ 4.
