All other embodiments, which can be made by one of ordinary skill in the art without undue burden from the present disclosure, are within the scope of the present application based on the embodiments herein.
In the following description, suffixes such as "module", "component", or "unit" for representing elements are used only for facilitating the description of the present application, and are not of specific significance per se. Thus, "module" and "component" may be used in combination.
In order to solve the problems mentioned in the background art, according to an aspect of the embodiments of the present application, an embodiment of a method for stopping operation of a target device is provided.
A method for stopping an operation of a target device in the embodiments of the present application may be performed by a target device, which may be a device having a memory, such as a refrigerator, an air conditioner, a washing machine, or the like.
The following will describe a method for stopping operation of a target device according to an embodiment of the present application in detail with reference to a specific embodiment, as shown in fig. 1, and the specific steps are as follows:
step 101: after the target device is powered on, the target timestamp is read from the memory of the target device, and the network connection state of the local clock in the target device is determined.
The target time stamp is the time stamp stored last time before the local clock is powered up.
In the embodiment of the application, the target device is provided with a local clock which runs all the time, the local clock can store a time stamp into a memory of the target device periodically before the target device is powered off, the target device reads the last stored target time stamp before the power off from the memory after the target device is powered on again, and then the network connection state of the local clock in the target device is determined. Wherein the network connection status includes a connected network and an unconnected network. Illustratively, the memory is a memory chip.
The local Clock in the present application is an RTC (Real Time Clock), and there are two implementations of the local Clock, namely hardware and software. The hardware RTC is an integrated hardware circuit with a clock chip, the software RTC is a code program of a clock timing function realized by using a chip timer and a software algorithm, and the local clock in the application is the software RTC.
Step 102: and determining the time stamp reference of the local clock according to the network connection state of the local clock and the target time stamp.
In the embodiment of the present application, if the local clock is connected to the network, the target clock updates the local clock according to the cloud timestamp, and then uses the cloud timestamp as a timestamp reference for running the local clock. If the local clock is not connected with the network, the target clock takes the acquired target time stamp as a time stamp reference of the running of the local clock.
Step 103: and according to the time stamp reference, under the condition that the local clock meets the preset storage condition, storing the current time stamp of the local clock into a memory once until the current time stamp exceeds the preset cut-off time stamp, and stopping running the target equipment.
In the embodiment of the application, the target device controls the target clock to start running from the time stamp reference, the target device stores the current time stamp of the local clock into the memory once every time the local clock meets the preset storage condition, and after the target device executes the storage process at least once, if the target device determines that the current time stamp is the same as the preset cut-off time stamp, the running time of the target device reaches the cut-off time, the running of the target device is stopped.
The target device is a rental device, and the rental device stops running when the current time stamp of the rental device is the same as the preset expiration time stamp.
In the method, the target device determines a time stamp reference of the local clock according to the network connection state of the local clock and the target time stamp, and controls the target clock to run from the time stamp reference. If the target device determines that the current time stamp is different from the preset cut-off time stamp, the current time stamp is stored in the memory, and if the target device is suddenly powered off at the moment, the stored current time stamp can be used as a target time stamp read after the next power-on; and if the target device determines that the current time stamp is the same as the preset cut-off time stamp, stopping running the target device.
When the target equipment is not connected with the network, the current time stamp can be determined through the target time stamp of the memory before power failure; when the target equipment is connected with the network, the current time stamp can be determined through the cloud time stamp, the target equipment in the method is not influenced by the network connection state, the current time stamp can be accurately determined, the situation that the target equipment cannot be accurately stopped to operate is avoided, and the benefits of renters are guaranteed.
As an alternative embodiment, determining the timestamp reference of the local clock from the networking conditions of the local clock and the target timestamp includes three cases:
case one: under the condition that the network connection state of the local clock is a connected network, acquiring a cloud timestamp from a cloud; under the condition that the cloud time stamp is different from the target time stamp, updating the local clock by taking the cloud time stamp as a reference; and taking the cloud time stamp as a time stamp reference of the local clock.
If the network connection state of the local clock is the connected network, the target device acquires a cloud time stamp from the cloud, and then judges whether the cloud time stamp is identical to the target time stamp. If the local clocks are different, the fact that the local clocks are not accurately operated is indicated, the target equipment updates the local clocks by taking the cloud time stamp as a reference, and the cloud time stamp is taken as a time stamp reference of the local clocks. In addition, the target device also stores the cloud timestamp to memory as the local clock has been updated.
And a second case: after the cloud time stamp is obtained from the cloud, taking the target time stamp as a time stamp reference of the local clock under the condition that the cloud time stamp is identical to the target time stamp.
And the target equipment judges whether the cloud time stamp is the same as the target time stamp, if so, the target time stamp is used as a time stamp reference of the local clock, and if the cloud time stamp is the same as the target time stamp, the local clock is accurately operated.
And a third case: when the network connection state of the local clock is unconnected, the target timestamp is used as a timestamp reference of the local clock.
And if the network connection state of the local clock is unconnected, taking the target timestamp as a timestamp reference of the local clock.
As an alternative embodiment, storing the current timestamp in the memory once in each case the local clock satisfies the preset storage condition includes two cases:
case one: acquiring the recording time length of a local clock, wherein the recording time length is the time length between the current time and the time when the current time stamp is stored in a memory; under the condition that the recording duration reaches a preset duration threshold value, acquiring a current time stamp of the local clock; the current timestamp is stored in memory.
The target device stores the current time stamp into the memory once every preset time length, and the specific process is as follows: the target equipment judges whether the recording time length reaches a preset time length threshold value or not from the moment when the current time stamp is stored in the memory last time to the moment when the current time stamp is stored in the memory as the recording time length, if not, the target equipment continues to judge, and if so, the current time stamp of the local clock is obtained and stored in the memory.
And a second case: after the local clock is updated by taking the cloud time stamp as a reference, storing the updated current time stamp into a memory.
If the target device determines that the cloud time stamp is different from the target time stamp, the local clock is updated by taking the cloud time stamp as a reference, and then the updated current time stamp is stored in the memory.
And after the local clock is updated by taking the cloud time stamp as a reference, re-determining the recording time according to the updated time stamp, so that the starting time of the recording time of the local clock is the same as the cloud time stamp stored in the memory.
In addition, if the local clock is updated by human or other devices, the updated current time stamp is also stored in the memory. The manual update time stamp is that a user manually corrects the local clock in a mode of key and display screen; updating the time stamp by the other device corrects the local clock of the target device by transmitting clock data by other neighboring devices.
As an alternative implementation manner, in the running process of the local clock, an automatic compensation mode is adopted to adjust the running error of the local clock so as to enable the recording time length of the local clock to be consistent with the actual time length.
In the embodiment of the application, in the running process of the local clock, the running error of the local clock can be adjusted in an automatic compensation mode, and the method comprises two modes, wherein the target device firstly determines the error time length of the local clock in the preset time length, and adds or subtracts the error time length on the basis of the preset time length when the recording time length of the local clock reaches the preset time length, so that the accurate time length is obtained, and the recording time length of the local clock is identical with the actual time length. In another mode, the target device avoids operation errors through an algorithm in the operation process, and the recording time length of the local clock is consistent with the actual time length when the recording time length of the local clock reaches the preset time length.
Illustratively, the preset time length is one hour, the error time length of the local clock is 10S more, and each time the local clock runs for one hour automatically, the displayed time stamp is subtracted by 10S by means of automatic compensation to obtain the current time stamp, and then the current time stamp is stored in the memory.
According to the method and the device, the error of the local clock is reduced in an automatic compensation mode, and the accuracy of the current time stamp of the local clock is improved.
As an optional implementation manner, the method and the device can be applied to leased air conditioner products, if the leased air conditioner is provided with NB-IOT communication modules, NB signals of some leased air conditioner installation positions are poor and unstable, the situation that the latest time cannot be synchronized exists, after a user places a lease air conditioner, the server can issue an expiration time for the lease air conditioner, the expiration time is stored in the air conditioner, whether the current time stamp exceeds the locking time is judged in real time, if yes, the lease is expired to lock the air conditioner, and the user can use the lease again. The method and the device can ensure the timed stop operation of the target equipment and avoid the loss of benefits of renters.
Optionally, the embodiment of the application further provides a process flow chart of a method for stopping operation of the target device, as shown in fig. 2, and the specific steps are as follows.
Step 1: the target device is powered up.
Step 2: the target time stamp is read from the memory chip.
Step 3: judging whether the target equipment is connected with a network, and if so, executing the step 4; if the network is not connected, executing the step 5;
step 4: judging whether the cloud time stamp is the same as the target time stamp, if so, executing the step 5; if not, executing the step 6;
step 5: the target timestamp is used as a timestamp reference of the local clock.
Step 6: and taking the cloud time stamp as a time stamp reference of the local clock.
Step 7: the local clock is run starting from the time stamp reference.
Step 8: if the recording time length of the local clock reaches the preset time length, determining the current time stamp of the local clock.
