Detailed Description
In order to make the objects, technical solutions and advantages of the present invention more clearly apparent, the technical solutions of the present invention are described in detail below with reference to the accompanying drawings and examples.
The embodiment of the application provides a device control method, and when a new state switching request is generated by a device according to a network condition, whether the device enters a safety mode is determined according to whether the device is in a network fluctuation state currently. According to the scheme, the equipment automatically switches between the working mode and the safety mode according to the network condition, so that the safety and the working efficiency of the equipment can be improved, and better user experience can be brought.
Referring to fig. 1, fig. 1 is a schematic diagram of a system architecture in an embodiment of the present application. In fig. 1, a terminal, such as a mobile phone terminal, is used to control a device through a server, and the device is connected to the server by using a known connection technology, such as Wifi, bluetooth, ZigBee, and the like, and the terminal and the server need to be connected to communicate through an internet network.
Under the system architecture of fig. 1, the device control process is explained in detail with reference to the accompanying drawings.
Referring to fig. 2, fig. 2 is a schematic flow chart of a device control process in the embodiment of the present application. The method comprises the following specific steps:
in step 201, when a new state switching request is generated according to the network condition at time T, the device determines the total number of the state switching requests generated within the time T-T.
Wherein T is a first preset time, i.e. the total number of state switching requests in the time T before the time T is determined.
The embodiment of the application provides two implementation modes for triggering and generating the state switching request under two conditions:
the first case of generating a state switching request:
when receiving a control instruction sent by a server, the equipment updates locally stored timestamp information by using the time information of the received control instruction; if the control instruction is received for the first time, storing the time information of receiving the control instruction as time stamp information;
the equipment determines whether the time corresponding to the locally stored timestamp information and the current time are greater than a first preset time threshold value or not;
when the equipment determines that the time corresponding to the locally stored timestamp information is not larger than a first preset time threshold from the current time, the equipment further determines that the equipment is in a safety mode at present, and generates a strip-state switching request; otherwise, no state switch request is generated.
The equipment determines that the equipment cannot be connected with the network when the time corresponding to the locally stored timestamp information is larger than a first preset time threshold from the current time; when the current working mode is further determined, generating a bar-shaped state switching request, wherein the content requested by the state switching request is switched from the working mode to the safety mode; otherwise, no state switch request is generated.
Second case of generating a state switching request:
the equipment periodically sends heartbeat data packets to the server; receiving response information of the server;
if the second preset time is up after the heartbeat data packet is sent, the response information of the server is not received and the server is currently in the working mode, generating a bar state switching request; and if the current mode is in the safe mode, not generating the state switching request. The state switching request is switched from the working mode to the safety mode.
If the response information of the server is received within a second preset time after the heartbeat data packet is sent and the server is currently in a safe mode, generating a bar state switching request; and if the current working mode is, not generating the state switching request.
In the specific implementation of the present application, the two situations of generating the state switching request occur without mutual influence.
When the network changes from abnormal to normal, the content of the state switching request is switched from a safe mode to a working mode;
when the network changes from normal to abnormal, the content of the state switching request is switched from the working mode to the safety 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, and the like, but is not limited to the examples given.
During specific implementation, a suggested safety mode pre-configured by the system can be provided according to different safety levels of the equipment for a user to select; to simplify the operation and improve the usability.
For example, for high-safety-level equipment such as an intelligent gas stove, an intelligent microwave oven, an intelligent electric cooker and the like, the preset safety mode is automatic shutdown, and for general safety-level equipment such as an intelligent air conditioner, an intelligent television and the like, the preset safety mode is automatic standby entering.
Step 202, if the device determines that the total number of the state switching requests is not less than a preset request threshold, determining whether the device is currently in a safe mode, and if so, maintaining the current safe mode; otherwise, switching to a safety mode; the flow is ended.
If the total number of the state switching requests is not smaller than the preset request threshold value, the current state is determined to be in a network fluctuation state, and in the state, the equipment needs to be in a safe mode.
In step 203, if the device determines that the total number of the state switching requests is smaller than the preset threshold, the device processes the content of the state switching request newly generated at the time t.
If the total number of the state switching requests is smaller than a preset threshold value, the current network state is good, the processing is carried out according to the content of the state switching requests, and if the request is that the working mode is switched to the safety mode, the equipment is switched from the working mode to the safety mode; and if the switching from the safety mode to the working mode is requested, switching the equipment from the safety mode to the working mode.
After the equipment enters the safety mode, when the equipment needs to be switched to the working mode, the equipment can be directly switched, the safety authentication mode can also be started, and a user performs authentication, such as password input, fingerprint input and the like, so that the equipment cannot be out of control or maliciously controlled when the equipment cannot be connected to a server, and the use safety of the intelligent equipment is enhanced.
In the following three scenarios, the situation that different devices implement device control is given in combination with practical applications, which is specifically as follows:
the first scenario is: the user leaves home for a long time, and under the condition that no one is on duty at home.
In order to meet the security protection requirement, a network and an intelligent camera (equipment in the embodiment of the application) in a home are kept in an open state before a user leaves the home, and a panoramic view in the home is monitored and displayed in real time.
And configuring a safety mode as a standby state, namely a low-energy consumption mode, and shooting a panoramic picture every half hour and storing the panoramic picture for the user to view.
After the user leaves home, the user can pay attention to the situation displayed by the intelligent camera at home through the terminal.
And monitoring the network condition by the intelligent camera, switching to a configured safety mode when the current network is determined to be a weak network, entering a standby state, shooting a panoramic picture every half hour, and storing.
When the current network environment is monitored to be recovered to be normal, the camera is switched to a normal working mode after user authentication is carried out, real-time monitoring is carried out, and a user can see a panoramic view in a home through the control terminal.
The second scenario is: when a user cooks rice by using the intelligent gas stove, the user finds that two seasonings are lacking in the family and temporarily goes out for purchase.
In order to not interrupt cooking, a user keeps the network and the intelligent gas stove in the home in an open state before going out, and sets a safety mode as follows: and automatically shutting off the fire, namely shutting down the equipment.
When the user goes out and the current environment of the gas stove is monitored to be a weak network, the gas stove is switched to a safe mode, namely, the fire is automatically turned off.
And when the current network environment is judged to be recovered to be normal, switching the gas stove back to the normal working mode after the user authentication is successful, and continuing to fire and cook.
The third scenario is: the user sets the safety mode of the intelligent air conditioner at home to be as follows: and automatically closing.
The user starts the intelligent air conditioner at home in advance through the mobile phone half an hour before work, but the intelligent air conditioner cannot be turned off on time when the user encounters an emergency during work, and the work turning time is unknown.
In order to avoid unnecessary waste, a user wants to turn off an intelligent air conditioner at home through a mobile phone, but if a network at home is abnormal, a mobile phone end prompts that equipment cannot be connected;
at the moment, the air conditioner judges that the current environment is a weak network, and switches the air conditioner to a safety mode defined by a user, namely, the air conditioner is automatically closed;
and when the current network environment is judged to be recovered to be 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 end as required.
In the three scenarios, when any one of the following occurs, it is determined that the current environment is a weak network environment:
in the first case:
when a control instruction sent by a server is received, if the difference value between the time corresponding to the locally stored timestamp information and the current time is larger than a first preset time threshold value, the weak network environment is determined to be in the current state.
In the second case:
