Detailed Description
In order to make the objects, technical solutions and advantages of the embodiments of the present invention clearer and more complete, the technical solutions in the embodiments of the present invention will be described below with reference to the drawings in the embodiments of the present invention, and it is obvious that the described embodiments are some, but not all, embodiments of the present invention, and based on the embodiments of the present invention, all other embodiments obtained by a person of ordinary skill in the art without creative efforts belong to the scope of the present invention.
As shown in fig. 1, an embodiment of the present invention provides a refrigerator power-off feedback method, which may include the steps of:
step 101: determining a first time at which a status signal was last received, wherein the status signal is periodically transmitted by the target refrigerator;
step 102: determining a second time, wherein the second time is the current time of the system;
step 103: judging whether the time interval between the first time and the second time is greater than a preset time threshold value or not;
step 104: and if the time interval is greater than the time threshold, sending power-off feedback information to the user terminal so that the user can determine the power supply state of the target refrigerator according to the power-off feedback information.
The refrigerator power-off feedback method provided by the embodiment of the invention comprises the steps of firstly determining the first time of receiving a state signal periodically sent by a target refrigerator at the last time, then determining the current time of the system as the second time, judging whether the time interval between the first time and the second time is greater than a preset time threshold value, and if the time interval between the first time and the second time is greater than the time threshold value, sending power-off feedback information to a user terminal so that a user can determine the power supply state of the target refrigerator according to the power-off feedback information. Therefore, the state signal cannot be continuously and periodically sent after the refrigerator is powered off, and as the power-off time of the refrigerator continues, the time interval between the first time and the second time is finally larger than the preset time threshold, and then power-off feedback information is sent to the user terminal, so that the user can be informed that the refrigerator is powered off within a short time after the refrigerator is powered off, the user can timely adopt corresponding measures, and the use experience of the user on the refrigerator can be improved.
In the embodiment of the invention, under the condition that the refrigerator is normally electrified and networked, the refrigerator uploads the state signals of the refrigerator according to a certain frequency through a network, wherein the state signals can comprise current data of the refrigerator, the temperature of a refrigerating chamber and other operation data, the time for receiving the state signals is determined while the state signals periodically sent by the refrigerator are received, and the time for receiving the state signals last time is determined as the first time, so that the effect of real-time monitoring is achieved, and the timeliness of the refrigerator power-off feedback method is further ensured.
In the embodiment of the invention, after the first time is determined, the current time of the system is determined to be the second time, and the current time of the system is determined to be the network time, so that the accuracy of the time is ensured, and the accuracy of the refrigerator power-off feedback method is further ensured.
In the embodiment of the invention, after the second time is determined, the time interval between the first time and the current time of the system is calculated, and the feedback of the power failure of the refrigerator is realized by judging the time interval and the preset time threshold. When the refrigerator is normally powered on and networked, the state signal periodically sent by the refrigerator is continuously received and the time is recorded, and the time interval between the calculated time for receiving the state signal and the current time of the system is smaller than a preset time threshold value. When the refrigerator is powered off, the state signal from the refrigerator cannot be received, so that the time interval between the last time the refrigerator receives the state signal before the power off and the current time of the system can only be calculated, at the moment, the last time the refrigerator receives the state signal is the last time the refrigerator sends the state signal before the power off, the current time of the system is synchronous with the network time, the time interval can be increased accordingly, when the time interval is larger than a preset time threshold, the refrigerator power off feedback device sends power off feedback information to a user terminal, the user can timely receive the feedback information of the power off sent by the refrigerator after the power off, corresponding measures can be timely taken, and the use experience of the user on the refrigerator is improved.
Alternatively, on the basis of the refrigerator power-off feedback method shown in fig. 1, after the power-off feedback information is sent to the user terminal, step 104 may determine whether the refrigerator is powered on again according to whether the status signal from the refrigerator is received again.
If the state signal from the refrigerator is received again, the power-on feedback information is sent to the user terminal, so that the user can determine that the refrigerator is powered up again according to the power-on feedback information received by the user terminal, the user can deduce the power failure duration according to the power-on feedback information and the power failure feedback information, the user can conveniently process articles in the refrigerator correspondingly, and the use experience of the user on the refrigerator is further improved.
Optionally, on the basis of the refrigerator power failure feedback method shown in fig. 1, step 103 sends a power failure time threshold to the user terminal after determining whether the time interval between the first time and the second time is greater than a preset time threshold, so that the user can infer the time when the refrigerator is powered off according to the power failure time threshold and the time when the user terminal receives the power failure feedback information on the premise of eliminating the power failure of the target refrigerator, where the actual power failure time is approximately a time point one time threshold before the power failure feedback information is received. The specific mode is as follows:
after the time interval between the first time and the second time is judged to be larger than the preset time threshold, the refrigerator can be determined to be powered off or disconnected, and the preset time threshold is sent to the user terminal, so that the user terminal can determine the time point of the time threshold before the power-off feedback information is received when the power-off feedback information is received according to the time and the time threshold of the power-off feedback information received by the user terminal on the premise of eliminating the power-off failure of the target refrigerator.
Optionally, on the basis of the refrigerator power failure feedback method shown in fig. 1, step 103 sends the first time and the second time to the user terminal after determining whether the time interval between the first time and the second time is greater than a preset time threshold, so that the user can determine that the refrigerator is powered off between the first time and the second time on the premise of eliminating the power failure of the target refrigerator. The specific mode is as follows:
after the time interval between the first time and the second time is judged to be larger than the preset time threshold, the refrigerator can be determined to be powered off or disconnected, and the first time and the second time are sent to the user terminal, so that the user can determine that the refrigerator is powered off after the first time and before the second time on the premise of eliminating the power failure of the target refrigerator.
Optionally, in the refrigerator power failure feedback method shown in fig. 1, in step 104, after the power failure feedback information is sent to the user terminal, the power failure feedback information is sent to the message center, so that the message center forwards the power failure feedback information to the user terminal, and the message center further processes the power failure feedback information in an information manner convenient for the user to intuitively understand.

Because the information interaction, execution process, and other contents between the units in the device are based on the same concept as the method embodiment of the present invention, specific contents may refer to the description in the method embodiment of the present invention, and are not described herein again.
As shown in fig. 5, an embodiment of the present invention provides a refrigerator power-off feedback system, including: a refrigerator 501, a refrigerator power-off feedback device 502 provided by any one of the above embodiments, and a user terminal 503;
the refrigerator 501 is used for periodically sending a state signal to a refrigerator power-off feedback device under the condition that power-off does not occur;
and the user terminal 503 is configured to receive the power failure feedback information from the refrigerator power failure feedback device and display the power failure feedback information to a user.
The refrigerator power-off feedback system comprises a refrigerator, a user terminal and a refrigerator power-off feedback device, wherein the refrigerator uploads a state signal of the refrigerator to the refrigerator power-off feedback device according to a certain frequency in a normal power-on networking state, the refrigerator power-off feedback device continuously receives the state signal from the refrigerator, determines the current time and the current time of the system at the same time, determines whether the refrigerator is powered off or disconnected by judging whether the current time and the current time of the system are greater than a preset time threshold value or not, and sends power-off feedback information to the user terminal. Therefore, the process of determining that the refrigerator is powered off is automatically completed by each module included in the refrigerator power-off feedback system, and a user does not need to participate in the refrigerator power-off feedback process, so that the use experience of the user on the refrigerator power-off feedback system can be improved.
The refrigerator power failure feedback method provided by the embodiment of the present invention is further described in detail below with reference to the refrigerator power failure feedback system shown in fig. 5, and as shown in fig. 6, the method may include the following steps:
step 601: the refrigerator power-off feedback device determines the time when the state signal from the refrigerator is received.
In the embodiment of the invention, the refrigerator power-off feedback system comprises a refrigerator, and under the condition of normal power-on networking, the refrigerator uploads a self state signal to the power-off feedback device according to a certain frequency, and the refrigerator power-off feedback device records the time when receiving the state signal from the refrigerator. When the refrigerator is powered off, the refrigerator cannot continuously send the state signal to the refrigerator power-off feedback device, and the time is the time when the refrigerator power-off feedback device receives the state signal last time before the power is turned off.
For example, in case of normal power-on, the refrigerator uploads its own operation data to the power-off feedback device at a frequency of 1s, and the refrigerator power-off feedback device records the time T while receiving a status signal from the refrigerator1. When the refrigerator is powered off, the refrigerator cannot continuously send operation data, T1The time when the refrigerator power-off feedback device receives the state signal last time before the power-off.
Step 602: the refrigerator power-off feedback device determines the current time of the system.
In the embodiment of the invention, the current time of the system is the network time.
For example, the refrigerator power-off feedback device records the current system time T once every 1s2。
Step 603: the refrigerator power-off feedback device judges whether the time interval between the time of receiving the state signal and the system time is greater than a preset time threshold, if so, the standard 604 is executed, otherwise, the step 601 is executed.
In the embodiment of the invention, after the refrigerator power-off feedback device determines the time of the received state signal and the system time, whether the time interval between the time of the received state signal and the system time is greater than a preset time threshold value or not is compared, if so, the subsequent steps can be participated, otherwise, the time of receiving the state signal from the refrigerator is continuously determined.
For example, the refrigerator power-off feedback device determines the time T for receiving the status signal every 1 minute by setting a calculation formula1And the current time T of the system2Comparing to obtain T1And T2The difference value is a time interval delta T, and then the time interval delta T is compared with a preset time threshold delta T to judge whether the delta T is larger than the delta T. If so, the subsequent steps can be participated, otherwise, the determination of the time T for receiving the status signal is continued1。
Step 604: the refrigerator power-off feedback device sends power-off feedback information to the user terminal.
In the embodiment of the invention, after the refrigerator power-off feedback device judges whether the time interval between the time of receiving the state signal and the system time is greater than the preset time threshold, if the time interval is greater than the time threshold, the user terminal receives the power-off feedback information sent by the refrigerator power-off feedback device.
Specifically, after the refrigerator power-off feedback device judges whether the time interval between the time of receiving the state signal and the system time is greater than a preset time threshold, the user terminal receives the power-off time threshold or the time of receiving the state signal for the last time and the system time, and then can determine the power-off time of the refrigerator according to the time on the premise of eliminating the power-off fault of the target refrigerator.
Specifically, after the user terminal receives the power failure feedback information sent by the refrigerator power failure feedback device, if the refrigerator sends a status signal to the refrigerator power failure feedback device again, it is determined that the refrigerator is powered on again, and the user terminal receives the feedback information for powering on again.
For example, the time T of the received status signal is determined for every minute1And system time T2Whether the time interval delta T between the two is larger than a preset time threshold delta T or not, and if the refrigerator is normally electrified and networked, the delta T is smaller than the delta T, the refrigerator power-off feedback device continues to monitor the refrigerator and receives a state signal from the refrigerator; and when the delta T is larger than the delta T, determining that the refrigerator is powered off or disconnected, and sending power-off feedback information to the user terminal, wherein the power-off feedback information reminds the user in a short message mode, an application program mode or a WeChat small program mode and the like. Meanwhile, when the delta T is judged to be larger than the delta T, the user terminal can also receive the delta T or T1And T2If the time threshold is 5 minutes, on the premise of eliminating the occurrence of the grid disconnection fault of the target refrigerator, the refrigerator power failure is inferred to occur 5 minutes before the power failure feedback information is received, or the refrigerator power failure occurs T1And T2Between time periods. After the power-off feedback information is sent to the user terminal, if the refrigerator sends the running data to the refrigerator power-off device again, the user terminal receives the feedback information of power-on recovery and determines the time of power-on recovery.

4. In the embodiment of the invention, after the second time is determined, the time interval between the first time and the current time of the system is calculated, and the feedback of the power failure of the refrigerator is realized by judging the time interval and the preset time threshold. When the refrigerator is powered off, the refrigerator power-off feedback device cannot receive the state signal from the refrigerator, so that the time interval between the latest time when the refrigerator receives the state signal before the power-off and the current time of the system can only be calculated, and when the time interval is greater than a preset time threshold, the refrigerator power-off feedback device sends power-off feedback information to the user terminal, so that the user can timely receive the feedback information sent by the refrigerator after the power-off, timely make corresponding measures, and improve the use experience of the user on the refrigerator.
5. In the embodiment of the invention, the refrigerator power-off feedback device can further send the time threshold, the first time and the second time and the incoming call feedback information to the user terminal, and on the premise of eliminating the network-off fault of the target refrigerator, the user can further deduce the power-off time and determine the incoming call time, so that the use experience of the user can be further improved.
