One embodiment of the invention discloses a kind of detection method of refrigerator, and as shown in Figure 1, the method can comprise the following steps:
Step 101: obtain the refrigerator state parameter being arranged on each sensor on the diverse location of refrigerator and gathering;

Step 102: utilize fuzzy control PID algorithm to process refrigerator state parameter, obtain result parameter;
Wherein, by fuzzy control PID algorithm, each refrigerator state parameter that each sensor gathers is processed, result parameter can be determined; Utilizing result parameter to judge, refrigerator is current whether there is incipient fault.
Such as, the discharge parameter gathered by the water flow sensing unit of fuzzy control PID algorithm to the condensation-water drain place being arranged on refrigerator is processed, and can determine the result parameter corresponding with discharge parameter;
The rotary speed parameter gathered by the speed probe of fuzzy control P IND algorithm to the compressor place being arranged on refrigerator is processed, and can determine the result parameter corresponding with rotary speed parameter.
Step 103: determine whether each sensor gathering refrigerator state parameter exists incipient fault in the position of refrigerator according to result parameter;
Wherein, result parameter obtains by processing refrigerator state parameter, and each refrigerator state parameter all gathered by corresponding sensor, and sensor setting is on a certain position of refrigerator, that is, can judge whether respective sensor exists incipient fault in refrigerator present position according to result parameter;
Such as, according to determining that to the result parameter after discharge parameter processes the water flow sensing unit gathering discharge parameter is in the position of refrigerator, namely whether condensation-water drain place exists incipient fault.
Can determine that the speed probe gathering rotary speed parameter is in the position of refrigerator according to the result parameter after processing rotary speed parameter, namely whether compressor exists incipient fault.
Concrete, in the present invention, determine whether the sensor gathering refrigerator state parameter exists incipient fault in the position of refrigerator, specifically can comprise according to result parameter:
Judge result parameter whether within the scope of the fault parameter of pre-stored;
Wherein, the fault parameter scope of all corresponding pre-stored of each sensor, by judging the fault parameter scope of the pre-stored of result parameter whether corresponding to respective sensor of the refrigerator state parameter that each sensor gathers, can determine whether the sensor corresponding to result parameter exists incipient fault in the position at refrigerator place.

It should be noted that, the fuzzy value domain of the fuzzy value domain of scale parameter, the fuzzy value domain of integral parameter and differential parameter is all determined according to lot of experimental data and experience, does not have the restriction of concrete numerical value in the present invention.
As a kind of way of realization of corresponding relation, the fuzzy control table corresponding to each sensor can be previously stored with in database, in each fuzzy control table, set up the domain corresponding relation of the domain of fuzzy value of each element and the scale parameter having the fuzzy subset of each element of the fuzzy subset of the domain of deviate and the domain of rate of change, the domain of the fuzzy value of integral parameter and the fuzzy value of differential parameter; Concrete, suppose in a certain fuzzy control table, walk crosswise mark successively and have each element of the fuzzy subset of the domain of deviate, perpendicular row marks each element of the fuzzy subset of the domain of the rate of changing successively, so, at the fuzzy value walking crosswise the corresponding fuzzy value of a scale parameter, the fuzzy value of integral parameter and differential parameter equal to each crosspoint of perpendicular row.
Suppose, determine that the deviate V1 of rotating speed is " just little " in the position of V={PB1, PM1, PS1, ZO1, NS1, NM1, NB1}, determine that the rate of change dV1/dt of rotating speed is " zero " in the position of dV/dt={PB2, PM2, PS2, ZO2, NS2, NM2, NB2}; So, the scale parameter K corresponding with " zero " of " just little " of deviate V1 and the rate of change dV1/dt of rotating speed is searched in a database
