In the specific embodiment of the invention, acceleration transducer is covered on the upper surface setting of compressor, parameter monitoring mould
Block 100 can obtain the acceleration and Oscillation Amplitude of compressor by acceleration transducer in real time.
Preferably, a sampling period can also be set, the sampling of driving acceleration transducer is primary in each sampling period, with
Calculation amount is reduced, is not described in detail herein.
Processing module 200 is for judging monitoring parameters whether in preset parameter range, if so, continue to monitor, if it is not,
Judge whether refrigerator breaks down according to the temperature of refrigerator.
In better embodiment of the present invention, multiple groups preset parameter range is configured according to the revolving speed of compressor, whenever compressor
When revolving speed changes, monitoring parameters are resurveyed.
In the process of running, revolving speed can be adjusted compressor according to the operating status of temperature, refrigerator in refrigerator；?
In the state of different temperature and difference, the running speed of compressor is different, correspondingly, corresponding to different revolving speeds, accordingly
Preset parameter range is set.Corresponding to the work at present revolving speed of compressor, if monitoring parameters are in preset parameter range, then it represents that
Refrigerator is in normal operating status, if needing to judge as the case may be the work of refrigerator not in preset parameter range
State.
Further, processing module 200 then judges to press for monitoring parameters not in preset parameter range according to monitoring parameters
Whether contracting machine resonates with other components in refrigerator except for the compressor, if so, adjusting pressure in preset parameter range
Contracting machine revolving speed, and resurvey monitoring parameters；If it is not, judging whether refrigerator breaks down according to the temperature of refrigerator.
It should be noted that preset parameter range is accordingly input in the control panel of refrigerator when refrigerator dispatches from the factory,
This corresponds in the preset parameter range that different compressor rotary speeds is set, and having preset the compressor will not be with its in refrigerator
He resonates at components, in this way, when monitoring parameters are in preset parameter range, without judging in compressor and refrigerator except pressure
Whether other components except contracting machine resonate.

Time judges that refrigerator breaks down if the state recurs the time greater than systemic presupposition time threshold.
The temperature of refrigerator may include temperature of refrigerating chamber, freezer temperature, and soft freezing chamber, may also include soft freezing chamber if it exists
Temperature, furthermore it is also possible to not do specifically repeat herein for environment temperature etc..
The preset temperature range is a temperature threshold range of the Current Temperatures corresponding to monitoring；Corresponding to refrigerator
Different operating statuses, different runing times, different external environments, the corresponding preset temperature range of Current Temperatures can be according to need
It specifically to adjust, in this example, which is one group of actual temp numerical value of corresponding a certain particular state.
In better embodiment of the present invention, if refrigerator Current Temperatures, which are not in preset temperature range, recurs the time
It is interrupted before being greater than systemic presupposition time threshold, then recurs the state is corresponding the time and be initialized as zero, with
Guarantee the accuracy of judgement.
Further, processing module 200 is also used to when the Current Temperatures for confirming refrigerator are not in preset temperature range
When Current Temperatures are lower than the minimum of preset temperature range, compressor rotary speed is reduced, Current Temperatures are higher than preset temperature range
Peak when, promoted compressor rotary speed；And when compressor rotary speed changes, resurveys monitoring parameters and judged.
Further, it when processing module 200 confirms that refrigerator breaks down, can also further give a warning, such as:
User is reminded by way of sound or icon flashing, certainly, if the refrigerator is intelligent refrigerator, can also directly pass through network mould
Block uploads fault message to part after sale, timely to be repaired.
In conclusion refrigerator of the invention, the control method and control system of the refrigerator, by pasting letter on the compressor
Number sensor, can resonate to avoid other of compressor and refrigerator components, and then reduce the operation noise of refrigerator, separately
Outside, it in conjunction with the signal transducer, can precisely monitor whether refrigerator breaks down, promote refrigerator overall performance.
