Detailed ways

In order to make the objectives, technical solutions and advantages of the present invention clearer, the technical solutions of the present invention will be described in detail below with reference to the accompanying drawings and embodiments.

An embodiment of the present application provides a device control method. When the device newly generates a state switching request according to network conditions, it determines whether to enter the safe mode according to whether it is currently in a network fluctuation state. In this solution, the device automatically switches between the working mode and the safe mode according to the network situation, which can improve the security and working efficiency of the device, and can also bring a better user experience.

Referring to FIG. 1, FIG. 1 is a schematic diagram of a system architecture in an embodiment of the present application. The terminal in FIG. 1, such as a mobile phone terminal, is used to control the device through the server, and the connection between the device and the server adopts a well-known connection technology, such as Wifi, Bluetooth, ZigBee, etc., and the terminal and the server need to communicate through the internet network connection.

Under the system architecture of FIG. 1 , the device control process is described in detail with reference to the accompanying drawings.

Referring to FIG. 2, FIG. 2 is a schematic flowchart of a device control process in an embodiment of the present application. The specific steps are:

Step 201, when a new state switching request is generated at time t according to network conditions, the device determines the total number of state switching requests generated within the time t-T.

Wherein, T is the first preset time, that is, the total number of state switching requests within T time before time t is determined.

The embodiments of the present application provide an implementation manner of triggering the generation of a state switching request in two cases:

The first case of generating a state switch request:

When receiving the control command sent by the server, the device uses the time information of receiving the control command to update the locally stored timestamp information; if it is the first time to receive the control command, the device stores the time information of receiving the control command as time stamp information;

The device determines whether the time distance corresponding to the locally stored timestamp information is greater than the current time by a first preset time threshold;

When the device determines that the time corresponding to the locally stored timestamp information is not greater than the first preset time threshold, and further determines that it is currently in the safe mode, a state switching request is generated; otherwise, no state switching request is generated.

When the device determines that the time corresponding to the locally stored timestamp information is greater than the first preset time threshold from the current time, it determines that it cannot connect to the network; and further determines that it is currently in the working mode, and generates a state switching request, the state switching request The content of the request is to switch from working mode to safe mode; otherwise, no state switching request is generated.

The second case of generating a state switch request:

The device periodically sends heartbeat data packets to the server; and receives the response information from the server;

If the second preset time expires after the heartbeat data packet is sent, the response information from the server has not been received, and the server is currently in working mode, a state switching request will be generated; if it is currently in safe mode, no state switching request will be generated. . The state switching request is to switch from the working mode to the safe mode.

If the response information from the server is received within the second preset time after the heartbeat data packet is sent, and the server is currently in the safe mode, a state switching request is generated; if it is currently in the working mode, no state switching request is generated.

When the present application is specifically implemented, these two situations of generating a state switching request will occur without affecting each other.

When the network changes from abnormal to normal, the content of the state switching request is to switch from the safe mode to the working mode;

When the network changes from normal to abnormal, the content of the state switching request is to switch from the working mode to the safe mode.

The specific content of the security mode in the embodiment of the present application may be configured according to the specific situation of the device, and may be set to turn off the device, enter a standby state, etc., but is not limited to the given example.

During specific implementation, a suggested security mode pre-configured by the system can also be given for the user to choose according to different security levels of the device, so as to simplify the operation and improve the usability.

For example, for high-security devices such as smart gas stoves, smart microwave ovens, and smart rice cookers, the default security mode is automatic shutdown. For general security-level devices such as smart air conditioners and smart TVs, the default security mode is automatically enter standby mode.

Step 202, if the device determines that the total number of state switching requests is not less than the preset request threshold, it determines whether it is currently in the safe mode, and if so, maintains the current safe mode; otherwise, switches to the safe mode; and ends the process.

If it is determined that the total number of state switching requests is not less than the preset request threshold, it is determined that the network is currently in a state of network fluctuation. In this state, the device needs to be placed in the safe mode. Therefore, when the device is currently in the safe mode, it is maintained in the safe mode. state, if currently in work mode, switch to safe mode.

Step 203 , if the device determines that the total number of state switching requests is less than the preset threshold, the device performs processing according to the content of the newly generated state switching requests at time t.

If it is determined that the total number of state switching requests is less than the preset threshold, the current network state is good, and the content of the state switching request is processed. Switch the safe mode to the working mode, then switch the device from the safe mode to the working mode.

After the device enters the security mode, when it needs to switch to the working mode, it can be switched directly, or the security authentication mode can be activated, and the user can authenticate, such as entering a password, fingerprint, etc., so as to ensure that the device will not be out of control when it cannot connect to the server. Or be maliciously controlled to enhance the security of the use of smart devices.

Combining with practical applications, the following three scenarios are given for different devices to realize device control, as follows:

The first scenario: when the user is away from home for a long time and the home is unattended.

In order to meet security requirements, the user keeps the network and the smart camera (the device in the embodiment of the present application) turned on before leaving the home, and monitors and displays the panoramic view of the home in real time.

And configure the safe mode as standby state, that is, low energy consumption mode, and shoot a panorama every half an hour and store it for users to view.

When the user leaves home, the user can pay attention to the situation displayed by the smart camera at home through the terminal.

The smart camera monitors the network situation. When it is determined that the current network is weak, it switches to the configured safe mode, enters the standby state, and takes a panorama image every half an hour and stores it.

When the monitoring current network environment returns to normal, the camera will be switched back to the normal working mode after user authentication, such as real-time monitoring, the user can see the panoramic view of the home through the control terminal.

Scenario 2: During the process of cooking with the smart gas stove, the user finds that two kinds of seasonings are missing at home, and temporarily goes out to buy.

In order not to interrupt the cooking, the user keeps the network and smart gas stove at home turned on before going out, and sets the safety mode to: automatically turn off the fire, that is, turn off the device.

When the user goes out, when the gas stove detects that the current environment is a weak network, the gas stove is switched to the safe mode, that is, the fire is automatically turned off.

When it is determined that the current network environment is back to normal, after the user authentication is successful, the gas stove is switched back to the normal working mode, and the cooking continues.

The third scenario: the user sets the safety mode of the smart air conditioner at home to: automatic shutdown.

The user turns on the smart air conditioner in the home through the mobile phone half an hour before going off work, but encounters an emergency when going off work, cannot go off work on time, and the off work time is unknown.

In order to avoid unnecessary waste, the user wants to turn off the smart air conditioner at home through the mobile phone, but the network at home is abnormal, and the mobile phone prompts that the device cannot be connected;

At this time, the air conditioner determines that the current environment is a weak network, and switches the air conditioner to the user-defined safety mode, that is, automatically shuts down;

When it is determined that the current network environment is back to normal, the air conditioner is switched back to the normal working mode after the user authentication is successful, and the user can continue to control the opening and closing of the air conditioner from the mobile phone as needed.

In the above three scenarios, when any of the following situations occurs, the current environment is determined to be a weak network environment:

The first case:

When receiving the control instruction sent by the server, if it is determined that the difference between the time corresponding to the locally stored time stamp information and the current time is greater than the first preset time threshold, it is determined that the current state is in a weak network environment.

Second case:

Periodically send heartbeat packets to the server; and receive response information from the server;

If after the heartbeat data packet is sent, the second preset time expires and no response information from the server is received, it is determined that it is currently in a weak network environment.
