Description

Technical Field

[0001] The present invention belongs to the technical field of household appliances, and more particularly, to a cloud platform authorization control method for intelligent devices. Background Art

[0002] Nowadays, more and more intelligent devices support network connection functions, and it is very convenient to remotely control or view the device status through a mobile terminal. Taking a washing and drying device as an example, when using a mobile terminal for remote control, since the user is not in front of the washing and drying device and cannot check the inside of the drum, there is a certain risk when directly remotely starting the program.

[0003] In the prior art, an Internet of Things washing machine can achieve remote control of the washing machine through sensing devices such as a computer and a smart terminal, and can also query the working status of the washing machine, and return relevant information of the washing machine through the control system. For some users without pets or children at home, the risk of remote startup is relatively small. However, for users with pets or children at home, there is a certain risk when remotely controlling the washing machine in an unauthorized state.

[0004] Therefore, a cloud platform authorization control method is provided. When authorizing through the cloud platform, control strategies can be formulated according to user models to meet the needs of different users and provide multiple control strategies. This allows users to safely and risk-free control devices using a mobile terminal. Summary of the Invention

[0005] The purpose of the present invention is to overcome the deficiencies of the prior art and provide a cloud platform authorization control method for intelligent devices, which can remotely control a washing machine while also being able to understand the running state of the washing machine in real time, thereby reducing the risk of remotely starting the program and improving the user experience.

[0006] To solve the above technical problems, the basic concept of the technical solution adopted by the present invention is:

[0007] A cloud platform authorization control method for intelligent devices includes: the cloud platform generates a user model according to user information and formulates different control strategies according to different user models;

[0008] When the cloud platform receives a control instruction, if it is a risk instruction, it issues the control instruction to the intelligent device according to the control strategy, and the intelligent device executes the control instruction;

[0009] If it is a safety instruction, it directly issues the control instruction to the intelligent device, and the intelligent device executes the control instruction.

[0010] Furthermore, the control strategy includes that the cloud platform determines whether to issue a control instruction to the intelligent device according to the drum door state of the intelligent device and / or the authorization state before executing the control instruction.

[0011] Furthermore, the cloud platform monitors the status of the intelligent device door in real time and records each time the door is opened and / or closed;

[0012] Before the smart device executes the risk instruction, it confirms the current door status. If there is no abnormality in the door status, the smart device executes the risk instruction.

[0013] Furthermore, a time period is set for the cloud platform to monitor the status of the barrel door. The time when the barrel door is closed is recorded as the start time of monitoring the barrel door status, and the time when the instruction is executed is recorded as the end time of monitoring the barrel door status. The cloud platform monitors the status of the barrel door within the set time period and records the information of each opening or closing of the barrel door.

[0014] Furthermore, during the time period of monitoring the status of the barrel door, if there is a record of the barrel door being opened and closed, the start time of monitoring the status of the barrel door is updated;

[0015] If there is only a record of the door being opened, the user will be prompted that the door is in an abnormal state.

[0016] Furthermore, before executing the risk instruction, it is determined whether the current door status is abnormal.

[0017] If it exists, the risk instruction will be refused to be executed or the risk instruction will be executed after the user confirms the current door status;

[0018] If it does not exist, the cloud platform sends a risk instruction to the smart device, and the smart device executes the risk instruction.

[0019] Furthermore, the smart device is connected to the cloud platform through communication, and the cloud platform authorization status is set in the display area of ​​the smart device;

[0020] Or the smart device enters the cloud platform authorization state when it is successfully connected to the cloud platform.

[0021] Further, when the smart device is powered on, the display area displays the current smart device authorization status;

[0022] If the smart device needs to release the cloud platform authorization status, the smart device display area will operate to release the authorization status;

[0023] The cloud platform authorization status is released, the cloud platform maintains a communication connection with the smart device, and the cloud platform detects the door status of the smart device.

[0024] Furthermore, when the smart device is in an unauthorized state, it will automatically shut down after being in standby mode for at least 2 minutes, and the door will be automatically unlocked.

[0025] Furthermore, when the smart device is in the cloud platform authorization state, the smart device can be remotely controlled without restrictions through the mobile terminal.

[0026] After adopting the above technical scheme, the present invention has the following beneficial effects compared with the prior art.

[0027] 1. Through the cloud platform authorization control method, different user models can be generated according to user information, and different control strategies can be formulated according to the user models, so as to ensure that the intelligent device conforms to the user's true intention when executing control instructions and reduce the execution of risk instructions.

[0028] 2. Different control strategies can be formulated for different user models to meet the personalized needs of users. For example, more strict control strategies can be set for families with children, while more flexible control strategies can be set for single users.

[0029] 3. The intelligent device and the cloud platform can achieve real-time monitoring and control to ensure that the device is in an authorized state, thereby improving the security and controllability of the device. Users can choose cloud platform authorization, long-term authorization status or single authorization status according to their own needs, which improves the operation convenience of users on the premise of meeting security requirements.

[0037] Embodiment 1

[0038] As Figure 1 shown, the cloud platform generates a user model based on user information and formulates different control strategies according to different user models;

[0039] When the cloud platform receives a control instruction, if it is a risk instruction, it issues the instruction to the intelligent device according to the control strategy, and the intelligent device executes the control instruction;

[0040] If it is a security instruction, it directly issues the instruction to the intelligent device, and the intelligent device executes the control instruction.

[0041] Formulating different control strategies according to the user model allows users to control intelligent devices according to their own needs and habits, providing a personalized experience. The cloud platform can identify risk instructions based on the user model and issue corresponding control strategies, effectively preventing unauthorized remote control instructions from posing security risks to intelligent devices and enhancing the security of the devices. Through two-way communication and authorization status, after the intelligent device is successfully connected to the cloud platform, the user's trust in the intelligent device can be increased, allowing the user to perform remote control with confidence, while improving the security of the device.

[0042] In this embodiment, taking a washing and drying device as an example, when the cloud platform receives a control instruction, if it is a risk instruction, it issues the instruction to the washing and drying device according to the control strategy, and the washing and drying device executes the control instruction;

[0043] If it is a security instruction, it directly issues the instruction to the washing and drying device, and the washing and drying device executes the control instruction.

[0044] The control strategy includes that the cloud platform determines whether to issue a control instruction based on the state of the drum door of the intelligent device and / or the authorization state before executing the control instruction.

[0045] The status of the cylinder door includes the cylinder door being open or closed. The abnormal status of the cylinder door includes the cylinder door being abnormally opened, the cylinder door not being closed, and when there is only an opening record of the cylinder door without a corresponding closing record, the user will also be prompted to confirm. It also includes that the cylinder door cannot be opened or closed due to other faults.

[0046] The current authorization status of the intelligent device includes the cloud platform authorization status, single - time authorization status, long - term authorization status, and un - authorized status.

[0047] The control strategy of this embodiment includes formulating different strategies according to the user model to meet the different needs of different users. The user model includes being set according to factors such as user age, family members, and whether there are pets; single young people are one category, couples or middle - aged couples are one category, families with three or four members or families with more than three members are one category, and further distinguish whether there are pets in each category of user model.

[0048] After the cloud platform receives a risk instruction, for the user model belonging to the single - young - people category, execute Strategy 1: The cloud platform does not monitor the status of the cylinder door of the intelligent device, sends an instruction to the intelligent device, and the intelligent device executes the control instruction.

[0049] For the category of couples or middle - aged couples with pets at home, execute Strategy 2: The cloud platform monitors the status of the cylinder door of the intelligent device in real - time, and sends the cylinder - door status information to remind the user every time the cylinder door is closed; when the cloud platform receives a control instruction and the user confirms the cylinder - door status, the cloud platform sends an instruction to the intelligent device, and the intelligent device executes the instruction.

[0050] The cloud platform monitors the status of the cylinder door of the device throughout the process. One way is that regardless of whether the intelligent device is in the on or off state, every time the cylinder door is closed, the cloud platform sends a message to remind the user, and after the cloud platform receives the instruction, it directly sends the instruction; another way is that the mobile - terminal device first displays all the closing records from the end of the last laundry to the present, and after the user confirms, the instruction is directly sent. If the user finds that the cylinder - door information is abnormal, such as there being an extra opening record in the middle, the user can choose to cancel the instruction sending.

[0051] For the category of couples or middle - aged couples without pets at home, execute Strategy 1.

[0052] Strategy 3: There are restrictions. According to the status of the cylinder door, strict restrictions are imposed to prohibit the sending of risky operation instructions. The cloud platform monitors the status of the cylinder door throughout the process. Regardless of whether the intelligent device is in the on or off state, every time the cylinder door is opened or closed, the cloud platform sends a message to remind the user. Judge whether there is an opening record of the cylinder door within a specified time period. If there is an opening record of the cylinder door, the instruction sending is prohibited; if there is no opening record of the cylinder door, the instruction is directly sent.

[0053] Set the time period for the intelligent device to monitor the status of the drum door. The time when the drum door is closed each time is recorded as the start time, and the end time for monitoring the status of the drum door is recorded as the time to execute the instruction. The cloud platform monitors the status of the drum door within the set time period.

[0054] For example, if the user places the clothes at 9:00 am and closes the drum door, then it is specified that the program start instruction is issued at 3:00 pm, and the opening and closing status of the drum door between 9:00 - 15:00 is monitored. If someone opens the drum door to put in clothes and closes it midway, the monitoring time is updated to the time of the most recent closing of the drum door until 15:00. If someone opens the drum door but forgets to close it midway, at 15:00, the user is reminded that the drum door information is abnormal and the instruction cannot be executed. After the user confirms, the user closes the drum door by himself and then confirms to execute the instruction. This strategy is applicable to families with three or four members or more than three members, and children between 1 and 10 years old.

[0055] The cloud platform monitors the status of the drum door of the intelligent device in real time and records the opening and / or closing information of the drum door each time;

[0056] Before the intelligent device executes the risk instruction, confirm the current status of the drum door. If the status of the drum door is normal, the intelligent device executes the risk instruction.

[0057] The cloud platform monitors whether there is abnormal information about the status of the drum door within the set time period;

[0058] If there is, the user needs to confirm the status of the drum door of the intelligent device before executing the instruction;

[0059] If not, the cloud platform sends an instruction to the intelligent device, and the intelligent device executes the instruction. This strategy is applicable to families with three or four members or more than three members, and there is a child under 1 year old at home.

[0060] Strategy 4: The status of the drum door is confirmed by the user and can be executed after confirmation. The cloud platform monitors the status of the drum door throughout the process and judges whether there is a record of the drum door being opened within the specified time period; if there is an opening record, the user is prompted and asked to confirm. After the user confirms, the instruction can be directly issued. Before the program runs through the entire process until the end of the program, the user can resend any instruction, such as restarting the program, etc., and the user does not need to confirm again.

[0061] For families with three or four members or more than three members, and children over 10 years old, the following strategy is implemented: The cloud platform monitors the status of the drum door of the intelligent device in real time and sends a reminder of the drum door status information to the user each time the drum door is closed;

[0062] The cloud platform receives the control instruction. After the user confirms the status of the drum door, the cloud platform sends the instruction to the intelligent device, and the intelligent device executes the instruction.

[0063] In particular, the start time of the time period set in strategy 3 can be set by the user himself or determined according to the state of the door. In order to avoid inconvenience in operation, multiple time periods can be pre-set in the smart device program library for users to choose; or the user clicks a specific button or key to confirm the start time each time the door is closed, and the time to execute the instruction can be fixed or advanced or extended by the user. This operation can be performed on the smart device or on the mobile terminal.

[0064] In the cloud platform authorization method of this embodiment, the smart device communicates with the cloud platform, and the cloud platform authorization status is set in the display area of ​​the smart device; or the smart device enters the cloud platform authorization status when the connection with the cloud platform is successful.

[0065] The display area operation of the smart device includes setting the cloud platform authorization method, which can also be set through the control area of ​​the smart device. The smart device includes a control area, and the control area is set with keys or buttons. Click or long press at least one key or button to enter the operation authorization interface; or, press or long press at least two keys at the same time to enter the operation authorization interface; after selecting the cloud platform authorization, the mobile terminal sends a control instruction, and the cloud platform determines whether it is a risk instruction. If it is a risk instruction, it sends the instruction to the smart device according to the control strategy corresponding to the user model, and the smart device executes the control instruction.

[0066] If the smart device does not receive the authorization instruction sent by the mobile terminal within the set time when it is in the operation authorization interface, the smart device will exit the operation authorization interface and the smart device will display that it is currently in an unauthorized state.

[0067] The device can provide additional security in the unauthorized state, which can prevent unauthorized access or operation. This helps protect the user's privacy and the security of the device. It provides options for long-term authorization status or one-time authorization status to help users flexibly control the connection and authorization status of the device according to actual needs. Users can choose the appropriate solution based on their usage habits and security needs.

[0068] Users can control the connection and authorization status of the device more freely, which improves their sense of control and satisfaction with the device. This helps improve user experience and ease of use.

[0069] In this embodiment, when the smart device is turned on, the display area displays the current authorization status of the smart device; if the smart device needs to release the cloud platform authorization status, the smart device display area operates to release the authorization status; after releasing the cloud platform authorization status, the cloud platform maintains a communication connection with the smart device, and the cloud platform detects the door status of the smart device.

[0070] Operations in the display area include pressing or long pressing at least one key or button to deauthorize, or selecting a specific program to deauthorize.

[0071] When the smart device is in the authorized state of the cloud platform, it can execute the power-on or power-off instruction at any time; when it is in the unauthorized state, the smart device will automatically shut down after standby for at least 2 minutes, and the cylinder door will be automatically unlocked at this time.

[0072] Users can easily understand the authorization status of the device to ensure that the connection and authorization status of the device meet the user's expectations. Through the operation of the buttons or display area of the smart device, the authorization status of the cloud platform can be lifted or cancelled. Users do not need additional devices or steps, which improves the convenience of operation. When the device is in the unauthorized state, shutting down after standby for at least 2 minutes can help save energy and reduce unnecessary power consumption. Automatically unlocking the cylinder door also helps to avoid incorrect operations or injuries to users. The device will automatically shut down and unlock when it is in the unauthorized state, which can prevent unauthorized operations and use and improve the security of the device.

[0073] When the smart device is in the authorized state of the cloud platform, the smart device can be remotely controlled without limitation through the mobile terminal.

[0074] After the cloud platform authorization setting is successful, the device can be remotely controlled without limitation. Users can control the smart device at any time and any place, which can be a mobile terminal. This means that users can remotely turn on or off the device, adjust the device settings, view the real-time status, etc., without being restricted by distance or environment. This unlimited remote control can provide a more convenient user experience. It is necessary to verify that the device can be remotely controlled without risk when it is in the authorized state.

[0075] If the smart device receives a risk instruction, when it is in the authorized state of the cloud platform, it obtains the control strategy according to the user model and judges whether to execute according to the control strategy.

[0076] If the cloud platform of the smart device is in the unauthorized state, the long-term authorization state or single authorization state can be set in the smart device operation. In some places or for some users, they may not need to use the cloud platform authorization for a period of time. To improve security, a long-term authorization or a single authorization control method is provided to meet the needs of different users and meet the growing needs of people for a better life.

[0077] When in the single authorization state, it will exit the single authorization state after executing this instruction;

[0078] When in the unauthorized state, the authorization setting function is started before refusing to execute the instruction; if the smart device does not receive the authorization instruction within the set time, it will refuse to execute the instruction and remain in the unauthorized state.

[0079] The cylinder door of the smart device is locked and remains in standby for at least 24 hours in the single authorization state.

[0080] In the single authorization state, the smart device receives the control command and determines whether it is a safety command or a risk command. If the risk command is issued remotely, the remote command is executed. If the remote control command is received in the long-term authorization or unauthorized state, it determines whether to execute it according to the long-term authorization state processing logic.

[0081] In the single authorization state, if the risk instruction is issued locally, it will be executed directly.

[0082] In the single authorization state, when the smart device receives a security command, it determines whether it is issued remotely. If it is issued remotely, it further determines whether it is an unlocking command. If the remote control command is an unlocking command, the command content is executed, but the door remains locked;

[0083] In the single authorization state, the smart device receives a security command. If it is a control command issued locally, if it is an unlocking command, it will execute the door unlocking command. If it is not an unlocking command, the door will remain locked and the command content will be executed.

[0084] For example, when the cloud sends a security command, such as a program pause command or a program end command, the smart device program is paused or ended, but the door remains locked.

[0085] The unlocking instruction includes unlocking the door after the program is paused, or unlocking the door after the program is finished.

[0086] In the single authorization state, the authorization state will be automatically released when the program ends after running the entire process.

[0087] When the smart device is turned on, it first checks the last authorization status. If the last authorization has not expired or has not been revoked, the command is executed. If the device is turned off after executing the control command, when the device restarts, the authorization needs to be verified again to ensure that the authorization verification is required every time the device restarts.

[0088] In the single authorization state, the smart device remains on standby for 24 hours, the door is locked, and when the door needs to be unlocked, an unlocking command can be issued locally. After the command is executed, the door is unlocked and the authorization state is automatically released. In the unauthorized state, the smart device will shut down after 2 minutes of standby, and the door will be unlocked.

[0089] In the long-term authorization state, it is necessary to first determine whether the instruction is a remote control instruction or a local control instruction. If the remote control instruction is a risk instruction, it is necessary to determine whether it is in the long-term authorization state. If so, execute the instruction; if not, further determine whether it is in the single authorization state. If so, execute the operation in the single authorization state; if not, refuse to execute the instruction.

[0090] In the long-term authorization state, if the remote control command is a safe command, the command will be executed.

[0091] In the long-term authorization state, if it is a local instruction, it is judged whether it is in the long-term authorization state. If so, the instruction is executed; if not, the operation under single authorization is executed.

[0092] The long-term authorization pre-mode is usually used in situations where the device needs to run for a long time or needs to be in a specific state all the time. Once the device enters the long-term authorization pre-mode, it will continuously execute specific functions or tasks for a period of time in the future without the user constantly authorizing or confirming.

[0093] The intelligent device includes a control area, and buttons or switches are set in the control area. Clicking or long-pressing at least one button or switch enters the single authorization state or the long-term authorization state;

[0094] Or, pressing or long-pressing at least two buttons simultaneously enters the single authorization state or the long-term authorization state.

[0095] If it is an unknown instruction or the device receives an instruction in the unauthorized state, both are refused to be executed. In the unauthorized state, it can be set to prompt the user whether authorization is required before executing the instruction;

[0096] In this embodiment, the security instructions include beeping, power on / off, unlocking instructions, and program jitter. Among them, the unlocking instruction can be program pause, program end, etc. When the user uses the intelligent device, the security instructions will not bring the possibility of risk to the user.

[0097] The risk instructions include program start, program continue to run, drying program, and washing program. The risk instructions are instructions that can affect the running state of the intelligent device, directly affect the state of the intelligent device, and there is a certain risk. Therefore, an authorization state needs to be set to ensure security.

[0098] The above are only the preferred embodiments of the present invention, and there is no any form of limitation to the present invention. Although the present invention has been disclosed above with the preferred embodiments, it is not used to limit the present invention. Any person skilled in the art can make some changes or modifications to the above-mentioned technical content to be equivalent changes within the scope of the technical solution of the present invention. The implementation schemes in the above embodiments can be further combined or replaced. However, as long as it does not deviate from the technical content of the present invention, any simple modification, equivalent change and modification made to the above embodiments according to the technical essence of the present invention still fall within the scope of the present invention.
