Detailed Description
The present invention will be described in detail below with reference to specific embodiments shown in the drawings. These embodiments are not intended to limit the present invention, and structural, methodological, or functional changes made by those skilled in the art according to these embodiments are included in the scope of the present invention.
The power supply of the refrigerator refers to supplying power to each module of the refrigerator, such as supplying power to a refrigeration module of the refrigerator or supplying power to a control panel of the refrigerator. The power supply abnormality of the refrigerator includes external power failure (e.g., power grid failure, trip or plug loose, etc.) and internal fault (e.g., fault such as short circuit).
As shown in fig. 1, the present invention provides a refrigerator power supply detection method, including:
step S01: and detecting the voltages of the high-voltage input end and the low-voltage output end of the power supply conversion module of the refrigerator.
The general refrigerator is provided with a power conversion module, the input end of the power conversion module is a commercial power input end, namely a high-voltage input end (generally about 220V), the output end is a low voltage (generally about 5V), and the power conversion module converts the input high voltage into the low voltage so as to supply power for other modules of the refrigerator.
Step S02: and if the voltage of the high-voltage input end is detected to be abnormal, or the voltage of the high-voltage input end is normal and the voltage of the low-voltage output end is abnormal, sending refrigerator power supply abnormal information to the terminal.
When the voltage of the high-voltage input end is abnormal, or the voltage of the high-voltage input end is normal and the voltage of the low-voltage output end is abnormal, the refrigerator is considered to be abnormally powered, and refrigerator power supply abnormal information is sent to a terminal (such as a mobile phone of a user). It should be noted that the terminal is a pre-bound terminal such as a mobile phone and a computer.
Specifically, if the voltage abnormality of the high-voltage input end is detected, the refrigerator external power-off reminding is sent to the terminal. And if the voltage of the high-voltage input end is normal and the voltage of the low-voltage output end is abnormal, sending a refrigerator internal fault prompt, an after-sale warranty suggestion and the like to the terminal. The invention divides the power failure condition of the refrigerator into external power failure and internal fault, and respectively sends corresponding alarm information to the user aiming at the two conditions, thereby helping the user to know the fault reason of the refrigerator more clearly and finding a solution faster. In addition, after the internal fault of the refrigerator is judged, the abnormity (internal fault) can be reported to an after-sales cloud platform of the refrigerator, so that an after-sales service department of the refrigerator can conveniently perform active after-sales service according to the abnormity.
It should be noted that the normal voltage at the high voltage input end means: the voltage V on the power supply inlet line of the refrigerator is within the interval of 0.9Ve-1.1Ve, wherein Ve is the voltage Ve of the line corresponding to the mains supply, and in China, the voltage Ve of the mains supply is 220V. The voltage abnormality of the high-voltage input end means that the voltage of the high-voltage input end is not in the interval of 0.9Ve-1.1Ve, and the voltage abnormality of most high-voltage input ends means that the voltage of the high-voltage input end is zero. Preferably, the voltage abnormality at the high-voltage input end of the present invention refers to a situation where the voltage at the high-voltage input end is zero due to a power failure or a trip of a power grid or a loose plug of a refrigerator. The voltage abnormality of the low-voltage output end means that the voltage of the low-voltage output end exceeds the range of the normal output voltage, and the condition is generally caused by internal fault short circuit. The normal output voltage of the low-voltage output end can be in the range of [4.5V-5.5V ].
In a preferred embodiment, when the voltage of the high-voltage input end is detected to be abnormal, or the voltage of the high-voltage input end is normal and the voltage of the low-voltage output end is abnormal, the temperature of each chamber of the refrigerator is periodically collected and sent to a terminal. By regularly pushing the temperature of each compartment of the refrigerator to a user, the user can clearly know the temperature condition in the refrigerator after power supply is abnormal, so that the user can take measures to respond. It should be noted that, when it is determined that the refrigerator is powered abnormally all the time, it is preferable to delay the time (for example, half an hour) to collect the temperature of the refrigerator compartment, because in this time, even if the refrigerator is not used for cooling, the influence on the food in the refrigerator is not great. In addition, to improve the accuracy of temperature detection, the temperature may be collected over a period of time (e.g., 1 minute) and then averaged.
The refrigerator power supply detection method judges the power supply condition of the refrigerator by detecting the voltage of the input end and the output end of the refrigerator power supply conversion module, and actively sends power supply abnormal information to a user when the power supply is abnormal, so that the user can conveniently and timely perform troubleshooting or make countermeasures.
In a specific embodiment, when the voltage at the input end of the refrigerator power conversion module is detected to be zero (or almost zero), it can be determined that the refrigerator is powered off externally, and the reason for the external power off may be that a power grid is powered off, a trip occurs, or a plug of the refrigerator is loose, and an external power off reminder is sent to a user at this time. When the voltage of the input end of the refrigerator power supply conversion module is detected to be normal, but the voltage of the low-voltage output end is abnormal, the internal fault of the refrigerator can be judged, the fault can be caused by the fact that an internal circuit is short-circuited, professional staff are required to carry out maintenance under the condition, and therefore a refrigerator internal fault prompt, an after-sale warranty suggestion and the like need to be sent to a user. In addition, after the internal fault of the refrigerator is judged, the abnormity (internal fault) can be reported to an after-sales cloud platform of the refrigerator, so that an after-sales service department of the refrigerator can conveniently perform active after-sales service according to the abnormity.
As shown in fig. 2, the present invention further provides a refrigerator power supply detection apparatus, which includes a high voltage detection module for detecting an external input voltage of a refrigerator (an input end voltage of a power conversion module of the refrigerator), a low voltage detection module for detecting an output end voltage of the power conversion module of the refrigerator, a communication module for communicating with a terminal, and a control module, wherein the control module is respectively connected to the three modules, and the control module is configured to determine whether the refrigerator is in power supply abnormality, and control the communication module to send refrigerator power supply abnormality information to the terminal when determining that the refrigerator is in power supply abnormality.
In a preferred embodiment, the control module is further configured to control the communication module to send a refrigerator external power-off prompt to the terminal when the voltage at the high-voltage input terminal is detected to be abnormal; the control module is also used for controlling the communication module to send refrigerator internal fault reminding and after-sale warranty suggestions and the like to the terminal when the voltage of the high-voltage input end is detected to be normal and the voltage of the low-voltage output end is detected to be abnormal. In addition, after the control module judges that the refrigerator has an internal fault, the control module can also control the communication module to report the abnormal (internal fault) to the after-sales cloud platform of the refrigerator, so that an after-sales service department of the refrigerator can conveniently perform active after-sales service according to the abnormal.
It should be noted that the device further includes a power supply module for supplying voltage to the modules, the power supply module is connected with other modules of the device one by one, and the power supply module may be a replaceable battery or the like. In a preferred embodiment, the power supply module is connected to a low-voltage output terminal of a power conversion module of the refrigerator, and the low-voltage output terminal is used for supplying power to each module of the device. Preferably, the power supply module comprises a charging and power storage circuit, when the refrigerator is normally powered, the low-voltage output end of the power supply conversion module of the refrigerator charges the charging and power storage circuit, and when the refrigerator is abnormally powered, the charging and power storage circuit supplies power to other modules of the device. Thus, the device of the present invention can continue to operate even if the refrigerator is powered off. Meanwhile, the battery does not need to be replaced regularly, so that the convenience is improved and the cost is saved.
In addition, in order to prevent the power supply module of the device from supplying power to the refrigerator reversely when the power supply of the refrigerator is abnormal, a mos tube or a relay is arranged between the power supply module and the low-voltage output end of the power supply conversion module of the refrigerator and used for ensuring unidirectional power supply of the low-voltage output end and the power supply module.
In a preferred embodiment, the device further comprises a temperature acquisition module, wherein the temperature acquisition module is connected with the control module and the power supply module and is used for acquiring the temperature of each compartment of the refrigerator. The temperature acquisition module comprises temperature sensors arranged in each compartment of the refrigerator. The control module controls the temperature acquisition module to periodically acquire the temperature of each chamber of the refrigerator when the power supply of the refrigerator is abnormal.
In another preferred embodiment, the control module is further provided with a timer, and the timer can be used for calculating the accumulated power-off time of the refrigerator and controlling the sampling time of the temperature collection module and the like.
In another preferred embodiment, the communication module is further configured to periodically push information such as accumulated time of power failure of the refrigerator and temperatures of compartments of the refrigerator to a user when power supply of the refrigerator is abnormal.
