Detailed Description
In order to make the objects, technical solutions and advantages of the present invention more apparent, the technical solutions of the present invention will be clearly and completely described below with reference to the specific embodiments of the present invention and the accompanying drawings. It is to be understood that the described embodiments are merely exemplary of the invention, and not restrictive of the full scope of the invention. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.
According to an embodiment of the present invention, a method for determining a power outage situation is provided, as shown in fig. 1, which is a schematic flow chart of an embodiment of the method of the present invention. The power outage situation determination method may include: step S110 to step S130.
At step S110, a current time is written into the set storage unit in a set period, and a time interval between the current time and a last time of last writing stored in the storage unit is obtained (for example, a time interval between clock times of two adjacent times of writing into the set storage unit is obtained). The storage unit may be a parallel storage unit such as a flash, which is to be determined whether a power-off condition exists.
Wherein, the time interval can be increased or decreased according to the requirement of a user.
For example: the user can select the time interval for detecting whether the refrigerator is powered off according to personal requirements, for example, the set interval can be 10 minutes, 20 minutes, 30 minutes, and so on. If the client sets the detection time to 20 minutes, the WiFi module writes the current time to the chip flash in a cycle of once every 20 minutes, and when the current time written twice is greater than 20 minutes, it can be inferred that the refrigerator is in the power-off state from the last time written to the latest time.
Therefore, the time interval is adjusted according to the user requirements, different reminding requirements of different users can be met, and flexibility and reliability can be guaranteed.
At step S120, it is determined whether the time interval is greater than a set time period.
At step S130, if the time interval is greater than the set time duration, it is determined that the powered device has a power failure condition within the time interval (e.g., it is determined whether the powered device to be determined has a power failure condition within the time interval). In a specific using process, if the time interval is less than or equal to the set duration, determining that the power-off condition of the electric equipment does not exist in the time interval, and continuously writing the current time into the set storage unit according to the set period.
For example: the method for judging the power failure of the refrigerator and reminding the user can be realized through software, and the hardware cost is not increased. The old device may also implement this functionality, such as through a software upgrade.
For example: under the condition that the hardware cost is not increased, the power-off reminding function of the refrigerator is realized by modifying the WiFi module program. If the current time can be written into the chip flash regularly, and when the written interval time is larger than a set value, the refrigerator can be judged to be powered off in the period.
For example: the WiFi module actively writes the current time into the flash after acquiring the current time, the WiFi module writes the current time into the flash again after the refrigerator normally operates for a period of time, the time written in the current time is compared with the time written in the last time, and when the time value between the two time intervals is larger than a set value, the refrigerator is judged to be powered off in the period.
Therefore, the current time is written into the storage unit, the time interval between the current time and the previous time is obtained, and the power failure of the electric equipment is determined under the condition that the time interval is longer than the set time length, so that the judgment on whether the electric equipment is powered off is convenient and reliable.
The execution subject for determining the power failure condition in the power failure condition determination method may include: the communication module of the electric equipment and/or the main control board of the electric equipment.
Specifically, if an execution main body of the power outage situation determination method may include a communication module of an electrical device, after determining the power outage situation through the communication module of the electrical device to obtain a determination result, directly prompting the determination result through the communication module of the electrical device when the determination result needs to be prompted.
For example: whether the refrigerator is powered off or not can be judged by utilizing the WiFi module of the refrigerator.
Specifically, if an execution main body of the power outage situation determination method may include a main control board of an electric device, after determining the power outage situation through the main control board of the electric device to obtain a determination result, the determination result is forwarded to any communication module through the main control board under the condition that the determination result needs to be reminded, and then the determination result is reminded through any communication module. The communication module may include a communication module of the electric device, or may include other communication modules besides the communication module of the electric device.
For example: the refrigerator power-off judging function is realized by a refrigerator main control board, the information is sent to the WiFi module after the call comes, and the WiFi module sends the information to the APP client and the cloud server to actively remind the user.
Therefore, the power-off condition of the electric equipment is determined through the multiple execution main bodies, so that the mode of determining the power-off condition of the electric equipment is more flexible and convenient.
In an alternative embodiment, the method may further include: and under the condition that the electric equipment is powered on, processing the determination result that the electric equipment has the power failure condition in the time interval.
With reference to the flowchart of fig. 2 showing an embodiment of processing the determination result of the power failure condition of the electric device in the time interval in the method of the present invention, a specific process of processing the determination result of the power failure condition of the electric device in the time interval is further described, which may include: step S210 and step S220.
Step S210, determining whether the powered device is powered back.
Step S220, if the power consumption equipment is powered on again, the power failure condition of the power consumption equipment in the time interval is reminded under the condition that a reminding function is started.
For example: after the refrigerator power-off information is detected, the WiFi module pushes the information to a mobile phone client of the user to remind the user.
For example: the power-off information can be actively pushed to the mobile refrigerator to remind the user.
Therefore, after the power failure condition of the electric equipment is determined, the power failure condition of the electric equipment in the corresponding time interval is reminded under the condition that the electric equipment is recovered to be powered on, a user can conveniently know the power failure condition, and the power failure condition is humanized.
Optionally, in step S220, the power failure condition of the electric device in the time interval is reminded, and at least one of the following power failure reminding processes may be included.
The first treatment process comprises the following steps: the process of reminding the power failure condition of the electric equipment may include: and initiating a first power-off reminding message of the power-off condition of the electric equipment in the time interval, and/or sending a second power-off reminding message of the power-off condition of the electric equipment in the time interval to a set client.
From this, through the long multiple mode of reminding of time to the outage, convenience of customers learns length of time of outage, and reminds the mode nimble and accurate.
And a second treatment process: and determining and reminding the occurrence time of the power failure condition of the electric equipment.
The following further describes, with reference to a flowchart of an embodiment of determining and reminding the occurrence time of the power failure condition of the electric device in the method of the present invention shown in fig. 3, a specific process of determining and reminding the occurrence time of the power failure condition of the electric device, which may include: step S310 and step S320.
And S310, determining the time period of the power failure condition of the electric equipment according to the time interval. For example: determining a time period during which the time interval is located.
For example: when the time value of the two time intervals is larger than the set value, the refrigerator is judged to be powered off in the period, and the power-off time of the refrigerator can be approximately calculated.
Step S320, initiating a first power-off time reminding message indicating that the power-off condition of the power-consuming device exists in the time period, and/or sending a second power-off time reminding message indicating that the power-off condition of the power-consuming device exists in the time period to the set client.
The client may be a client such as a mobile phone that establishes a binding relationship with the electric device in advance.
For example: if the refrigerator outage condition appears, treat that the refrigerator is gone up the electricity and resume the network after, the wiFi module gives cell-phone APP customer end with refrigerator outage information transmission, reminds the time quantum and the length of time of user's refrigerator outage, has solved the problem that the user is not aware of when the refrigerator outage condition appears.
Therefore, through various reminding modes of the power-off time period, a user can know the power-off time period conveniently, and the reminding mode is flexible and accurate.
In an alternative embodiment, the method may further include: and in the case that the electric equipment can comprise a refrigerator, judging and processing whether food stored in the refrigerator is deteriorated or not under the condition that the refrigerator is powered off within the time interval.
With reference to the flowchart of fig. 4 showing an embodiment of determining and processing whether food stored in the refrigerator will deteriorate when the refrigerator is powered off within the time interval, a specific process of determining and processing whether food stored in the refrigerator will deteriorate when the refrigerator is powered off within the time interval will be further described, which may include: step S410 and step S420.
Step S410, under the condition that the electric equipment can comprise a refrigerator, acquiring the types of food stored in the refrigerator and the quality guarantee period under the condition that the refrigerator is powered off.
Step S420, determining whether the power-off condition of the refrigerator in the time interval can cause the corresponding food to deteriorate or not according to the category and the quality guarantee duration, and sending a determination result that the power-off condition of the refrigerator in the time interval causes the corresponding food to deteriorate or not to deteriorate to a set client.
For example: can be when the outage propelling movement, intelligent refrigerator can provide the life wisdom and supply the user to judge whether food damages.
Therefore, whether food stored in the refrigerator is deteriorated or not is judged and processed under the condition that the refrigerator is powered off within the time interval, so that the food can be conveniently and correspondingly processed by a user, and the convenience and the humanization of the user are better.
In an alternative embodiment, the method may further include: and (3) performing clock synchronization on the current time of writing (namely, the current time of writing to the set storage unit).
The following further describes a specific process of performing clock synchronization on the current time of writing with reference to a flowchart of an embodiment of performing clock synchronization on the current time of writing in the method of the present invention shown in fig. 5, which may include: step S510 and step S520.
Step S510, obtaining the current network time before writing the current time into the set storage unit according to the set period.
Step S520, performing clock synchronization processing on the current time according to the current network time, so as to write the current time after the clock synchronization processing into the storage unit.
For example: can be networked through wireless communication module (not limit WiFi), can real-time synchronization network time, reliably judge outage duration, outage time, circular telegram time etc..
For example: after the WiFi module is powered on, the user binds the refrigerator equipment with the mobile phone client of the user, and the successful binding indicates that the WiFi module is connected to a network. The WiFi module synchronizes time with the server every time when connecting to the network, and after the time synchronization is completed, the WiFi module has a clock function.
Therefore, the clock synchronization is carried out on the current writing time, so that the accuracy of the writing time is improved, and the accuracy and the reliability of the determination of the power-off time interval are improved.
Through a large number of tests, the technical scheme of the embodiment is adopted, the current time is written regularly, and the refrigerator is judged to be powered off in the period when the written interval time is greater than a set value, so that the judgment on the power-off condition of the refrigerator is convenient and reliable.
According to the embodiment of the invention, a power failure situation determination device corresponding to the power failure situation determination method is also provided. Referring to fig. 6, a schematic diagram of an embodiment of the apparatus of the present invention is shown. The power outage situation determination apparatus may include: a processing unit 102 and a determination unit 104.
In an alternative example, the processing unit 102 may be configured to write the current time to the set storage unit in a set period, and obtain a time interval between the current time and a last time of the last write stored in the storage unit (e.g., obtain a time interval between clock times of two adjacent writes to the set storage unit). The storage unit may be a parallel storage unit such as a flash, which is to be determined whether a power-off condition exists. The specific functions and processes of the processing unit 102 are shown in step S110.
Wherein, the time interval can be increased or decreased according to the requirement of a user.
For example: the user can select the time interval for detecting whether the refrigerator is powered off according to personal requirements, for example, the set interval can be 10 minutes, 20 minutes, 30 minutes, and so on. If the client sets the detection time to 20 minutes, the WiFi module writes the current time to the chip flash in a cycle of once every 20 minutes, and when the current time written twice is greater than 20 minutes, it can be inferred that the refrigerator is in the power-off state from the last time written to the latest time.
Therefore, the time interval is adjusted according to the user requirements, different reminding requirements of different users can be met, and flexibility and reliability can be guaranteed.
In an alternative example, the determining unit 104 may be configured to determine whether the time interval is greater than a set time duration. The specific function and processing of the determination unit 104 are referred to in step S120.
In an optional example, the determining unit 104 may be further configured to determine that the powered device has a power failure condition in the time interval if the time interval is greater than the set time duration (for example, determine that the powered device, for which it is to be determined whether the power failure condition exists, has a power failure condition in the time interval). In a specific using process, if the time interval is less than or equal to the set duration, determining that the power-off condition of the electric equipment does not exist in the time interval, and continuously writing the current time into the set storage unit according to the set period. The specific function and processing of the determination unit 104 are also referred to in step S130.
For example: the method for judging the power failure of the refrigerator and reminding the user can be realized through software, and the hardware cost is not increased. The old device may also implement this functionality, such as through a software upgrade.
For example: under the condition that the hardware cost is not increased, the power-off reminding function of the refrigerator is realized by modifying the WiFi module program. If the current time can be written into the chip flash regularly, and when the written interval time is larger than a set value, the refrigerator can be judged to be powered off in the period.
For example: the WiFi module actively writes the current time into the flash after acquiring the current time, the WiFi module writes the current time into the flash again after the refrigerator normally operates for a period of time, the time written in the current time is compared with the time written in the last time, and when the time value between the two time intervals is larger than a set value, the refrigerator is judged to be powered off in the period.
Therefore, the current time is written into the storage unit, the time interval between the current time and the previous time is obtained, and the power failure of the electric equipment is determined under the condition that the time interval is longer than the set time length, so that the judgment on whether the electric equipment is powered off is convenient and reliable.
The execution subject for determining the power failure condition in the power failure condition determination device may include: the communication module of the electric equipment and/or the main control board of the electric equipment.
Specifically, if the execution main body of the power outage situation determination apparatus may include a communication module of the electrical device, after the power outage situation is determined by the communication module of the electrical device to obtain the determination result, the determination result is directly reminded by the communication module of the electrical device when the determination result needs to be reminded.
For example: whether the refrigerator is powered off or not can be judged by utilizing the WiFi module of the refrigerator.
Specifically, if the execution main body of the power outage situation determination apparatus may include a main control board of an electric device, after determining the power outage situation through the main control board of the electric device to obtain a determination result, the determination result is forwarded to any communication module through the main control board under the condition that the determination result needs to be reminded, and then the determination result is reminded through any communication module. The communication module may include a communication module of the electric device, or may include other communication modules besides the communication module of the electric device.
For example: the refrigerator power-off judging function is realized by a refrigerator main control board, the information is sent to the WiFi module after the call comes, and the WiFi module sends the information to the APP client and the cloud server to actively remind the user.
Therefore, the power-off condition of the electric equipment is determined through the multiple execution main bodies, so that the mode of determining the power-off condition of the electric equipment is more flexible and convenient.

Since the processes and functions implemented by the apparatus of this embodiment substantially correspond to the embodiments, principles and examples of the method shown in fig. 1 to 5, the description of this embodiment is not detailed, and reference may be made to the related descriptions in the foregoing embodiments, which are not repeated herein.
Through a large number of tests, the technical scheme provided by the invention has the advantages that the current time is written regularly, the refrigerator is judged to be powered off in the period when the written interval time is greater than a set value, the network time can be synchronized in real time, the power-off time, the power-on time and the like can be reliably judged, and the judgment accuracy is good and the reliability is high.
According to an embodiment of the present invention, there is also provided a refrigerator corresponding to the power outage situation determination apparatus. The refrigerator may include: the above-described power outage situation determination apparatus.
In an optional embodiment, in consideration of the fact that no software function for judging the power-off duration, the power-off time point and the power-on time point of the refrigerator is realized at present, the scheme of the invention provides a method for judging the power-off of the refrigerator and reminding a user, and the method can be realized through software without increasing hardware cost.
Optionally, the solution of the present invention may also implement that the old device also implements the function by software upgrade.
Optionally, in the scheme of the present invention, networking may also be performed through a wireless communication module (without limitation to WiFi), so that network time can be synchronized in real time, and power-off duration, power-off time, power-on time, and the like can be reliably determined.
Optionally, in the scheme of the invention, the power failure information can be actively pushed to the mobile refrigerator to remind the user.
Optionally, in the scheme of the invention, the intelligent refrigerator can provide life little knowledge for a user to judge whether food is damaged or not while power-off pushing is performed.
In an optional example, the scheme of the invention can realize the power-off reminding function of the refrigerator by modifying the WiFi module program under the condition of not increasing the hardware cost.
Optionally, in the scheme of the present invention, the current time may be periodically written into the chip flash, and when the written interval time is greater than a set value, it may be determined that the refrigerator is powered off during this period.
For example: the chip can comprise a flash of a WiFi module main control chip, does not need to be specific to the model, and is universal. Optionally, the place for storing the time may also be designed as a flash of the main control chip of the display panel of the refrigerator or a flash of the main control chip of the refrigerator.
Specifically, according to the scheme of the invention, whether the refrigerator is powered off or not can be judged by utilizing the WiFi module of the refrigerator, if the refrigerator is powered off, after the refrigerator is powered on and the network is recovered, the WiFi module transmits refrigerator power-off information to the mobile phone APP client, so that the time period and the time length of the refrigerator power-off of a user are reminded, and the problem that the user is not aware of the refrigerator power-off condition is solved.
In an alternative embodiment, reference may be made to the example shown in fig. 7 to illustrate a specific implementation process of the scheme of the present invention.
In an alternative specific example, referring to the example shown in fig. 7, a method for determining a power failure of a refrigerator and reminding a user according to an aspect of the present invention may include:
step 1, after the WiFi module is powered on, the user binds the refrigerator equipment with the mobile phone client of the user, and the successful binding indicates that the WiFi module is connected to a network. The WiFi module synchronizes time with the server every time when connecting to the network, and after the time synchronization is completed, the WiFi module has a clock function. The WiFi module actively writes the current time into the flash after acquiring the current time, the WiFi module writes the current time into the flash again after the refrigerator normally operates for a period of time, the time written in the current time is compared with the time written in the last time, when the time value between the two time intervals is larger than a set value, the power failure of the refrigerator in the period is judged, and the power failure time of the refrigerator can be roughly calculated.
For example: and calculating the accuracy of the power-off time, namely the interval between the current time of the current writing and the current time of the last writing. Examples are: the method comprises the steps that under the condition of normal work, a WiFi module writes current time into flash every 10 minutes, assuming that the writing time is 20 days at 12 months in 2018, 18:30 at 12 months in 2018, 18:40 at 20 days at 12 months in 2018, the writing time for the next time is 18:33 at 20 days at 12 months in 2018, the power failure is divided, the normal power supply time is 19:25 at 12 months in 2018, the normal power supply time is 19:25 at 20 days at 12 months in 2018, the power restoration time and the power failure time at 20 days at 12 months in 2018 are written immediately after the WiFi module is powered on, the time interval between the recording and the last recording is calculated to be equal to 55 minutes from 20 days at 12 months in 2018, 19:25 at 20 months in 2018, 18:30 at 20 days at 20 months in 2018, and the actual power failure time is. From the above example, we see that this calculated time has a 3 minute error. The time of the refrigerator power failure is calculated according to the method, a certain error exists, the error is less than or equal to the time interval of the recording time, and the dynamic adjustment can be carried out. The refrigerator is powered off for a short period of time, and the stored food is generally not affected, so that the error does not affect the implementation of the function.
And 2, after the refrigerator power-off information is detected, the WiFi module pushes the information to a mobile phone client of the user to remind the user.
When the function is closed by the user, the WiFi module does not perform regular time writing operation on the flash or push a judgment result to the user; when the user starts the function, WiFi can write the current time to the flash regularly, judge whether the refrigerator is in a power-off condition, and immediately push a related power-off message to the mobile phone client of the user after detecting that the power-off condition occurs.
For example: the time for writing flash before power failure is 18:30 in 12 months and 20 days in 2018, but the actual power failure time is 18:33 in 12 months and 20 days in 2018. The value used in the calculation is 2018, 12, 20, 18:30, so it is advanced.
Optionally, on the mobile phone client, when the user turns on the function, the user may select a time interval for detecting whether the refrigerator is powered off according to personal needs, for example, the set interval may be 10 minutes, 20 minutes, or 30 minutes.
For example: if the client sets the detection time to 20 minutes, the WiFi module writes the current time to the chip flash in a cycle of once every 20 minutes, and when the current time written twice is greater than 20 minutes, it can be inferred that the refrigerator is in the power-off state from the last time written to the latest time.
It should be noted that the time of the power-off action determined by the WiFi module is an approximate value, which is earlier than the actual occurrence value, but the number of minutes ahead of the time is less than the time interval set by the user for determining whether the refrigerator is powered off, and the power-off operation within the time of this error value does not damage the articles stored in the refrigerator; the WiFi module judges that the time for recovering the power-on of the refrigerator is accurate.
For example: since the wireless network module (WiFi module) synchronizes time to the server immediately after the power is restored, the time obtained is accurate.
For example: xiaoming suddenly receives the notice of the company, a week comes in business tomorrow, but just puts foods such as meat, yoghourt and the like bought in a supermarket tonight at night into a refrigerator. Since the small and clear living place is occasionally powered off irregularly, the user worrys that the food in the refrigerator is deteriorated due to the power-off condition during the business trip, the user can start the power-off reminding function of the refrigerator by using the mobile client, the time interval for detecting the power-off is set to be 20 minutes, the user knows that the food in the refrigerator is not deteriorated if the power-off of the refrigerator is within 20 minutes, and the user can go on business safely. When the user is on the difference, the user can eat the food of the refrigerator safely or discard the food by only checking whether the prompt message of the mobile phone client side has the 'refrigerator power-off' push message.
In an alternative specific example, the refrigerator power-off judgment function is realized by a refrigerator main control board, the information is sent to a WiFi module after a call is made, and the WiFi module sends the information to an APP client and a cloud server to actively remind a user.
