Detailed Description
The technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the drawings in the embodiments of the present application, and it is obvious that the described embodiments are only a part of the embodiments of the present application, and not all of the embodiments. 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 application.
With the continuous development of the internet of things technology and the communication technology, besides the smart phone, the tablet computer and other devices, more electronic devices have the capability of accessing the network. For example, electronic devices such as smart meters, door sensors, body sensors, door and window sensors, temperature and humidity sensors, water sensors, natural gas alarms, smoke alarms, wall switches, wall sockets, smart sockets, wireless switches, wireless wall switches, curtain motors, multifunctional gateways, air conditioner partners, projectors, projection screens, smart curtain motors, smart speakers, cameras, and the like.
The electronic device can be accessed to the network through the wireless access device in the process of accessing to the network. Specifically, the electronic device may send an access request to the wireless access device after scanning to be within a signal coverage of the wireless access device, and then enter an authentication phase. In the authentication stage, the electronic equipment sends the acquired access password to the wireless access equipment for verification, and after the verification is passed, data interaction with the router can be carried out, so that the electronic equipment is accessed into the network through the router. The electronic equipment can trigger the user to input the access password through the input interface, and can also directly read the access password which is input by the user history and stored locally.
The inventor finds in research that the access password stored in the wireless access device is changed sometimes. After the access password configured in the wireless access device is changed, the other electronic devices must also use the changed access password for authentication to establish a communication connection with the wireless access device. The modification operation of the access password used by other electronic devices usually must be completed by manual operation of the user, which causes great inconvenience to the user. In addition, when the number of devices requiring access password updating is too large, more inconvenience is brought to the user.
Therefore, the inventor proposes a data updating method, a device and an electronic device in the application, which can improve the above problems. Therefore, after the access password in the wireless access equipment is updated, the electronic equipment can acquire the updated access password through the broadcast data packet sent by other communication modes, and further the user does not need to manually enter the updated password again, and the user experience is improved.
An operating environment for the embodiments of the present application will be described.
As shown in fig. 1, in the operating environment shown in fig. 1, wireless access device 99 may transmit a broadcast signal based on the second communication mode. The dashed line represents the coverage of its broadcast signal. While an electronic device within the coverage area of its broadcast signal may receive the data packets carried by the broadcast signal. Such as electronic device 98 and electronic device 97 in the figure. In order to facilitate that only the designated electronic device can receive the broadcasted data packet, the wireless access device 99 may add an identifier for identifying the electronic device to the broadcast signal, thereby implementing broadcasting of the directional data packet. For a directional packet, only the electronic device corresponding to the directional packet can actually acquire the directional packet, while for an electronic device not corresponding to the directional packet, the electronic device discards the directional packet even after receiving the directional packet. It will be appreciated that the electronic device identified by the identification of the electronic device carried in the orientation packet is the electronic device corresponding to the orientation packet.
Embodiments of the present application will be described in detail below with reference to the accompanying drawings.
Referring to fig. 2, a data updating method provided in the embodiment of the present application is applied to an electronic device, and the method includes:
step S110: and acquiring a directional data packet broadcasted based on a first wireless communication mode, wherein the directional data packet carries an identifier of the electronic equipment, and the identifier is used for the electronic equipment to identify target receiving equipment of the directional data packet.
It should be noted that both the electronic device and the wireless access device can support multiple communication modes. For example, both the first communication method and the second communication method may be supported. In this embodiment of the present application, the second communication mode is a communication mode adopted by the wireless access device to implement wireless access to the electronic device. The wireless access of the electronic equipment refers to that the electronic equipment accesses public network resources through the wireless access equipment. As one mode, the first communication mode may be an infrared communication mode, a bluetooth communication mode, or a ZigBee communication mode, and the second communication mode may be based on WiFi communication. After the wireless access device acquires the updated access password, the directional data packet broadcasted based on the first wireless communication mode is used for the electronic device to acquire the updated access password.
It can be understood that, if the electronic device is in the coverage area of the broadcast signal of the wireless access device based on the second wireless communication mode, the directional data packet broadcast by the wireless access device can be acquired. In the actual operation process of the electronic device, in order to achieve the effect of saving the electric quantity, the electronic device does not start the first wireless communication module based on the first wireless communication mode communication in real time.
As a way, the electronic device may trigger to start the first wireless communication module when detecting that the electronic device is in the designated scene, so that the electronic device receives the data packet transmitted based on the first wireless communication mode through the first wireless communication module.
In the embodiment of the present application, the electronic device may detect whether the electronic device is in the aforementioned specific scenario in various ways.
And as a mode, when a failure of establishing communication connection with the wireless access equipment based on a second communication mode based on a locally stored access password is detected, judging that the wireless access equipment is in the specified scene.
It can be understood that, if the electronic device has already established a communication connection with the wireless access device, in such a process, if the access password corresponding to the wireless access device is updated, the already established communication connection between the electronic device and the wireless access device is broken. For the electronic device, after the first wireless module is started, the wireless access device which has been successfully connected in history is automatically connected. In this case, since the access password corresponding to the wireless access device is updated, the electronic device may be in a failure state during the process of establishing a communication connection with the wireless access device based on the second communication method based on the locally stored access password. In order to facilitate that the electronic device can quickly and automatically acquire the updated access password after the access password of the wireless access device is updated, the electronic device can trigger to open the first wireless communication module when the communication connection between the electronic device and the wireless access device based on the second communication mode fails to be established based on the locally stored access password, so that the directional data packet broadcasted by the wireless access device based on the first wireless communication mode can be received.
In addition, as another mode, when the electronic device detects that the wireless access device is within a specified location range, it determines that the wireless access device is in the specified scene.
It can be understood that the electronic device can acquire the position information of the electronic device in real time by configuring the positioning module. For example, optionally, when the positioning module is a GPS module, the electronic device may acquire longitude and latitude as the position information through the GPS module. Correspondingly, the electronic device can also store the position information of the wireless access device. Optionally, after establishing a communication connection with the wireless access device, the electronic device may acquire current location information of itself as location information of the currently connected wireless access device. In this case, the electronic device may periodically obtain current location information of the electronic device, compare the current location information with locally stored location information of the wireless access device that is historically connected to the electronic device, and if the electronic device detects that the electronic device is located within a specified location range of a certain wireless access device, it is determined that a connection may be established with the wireless access device, and then the first wireless communication module may be started in advance, so that an updated access password may be obtained in time.
It should be noted that, usually, the location information acquired by the GPS module is longitude and latitude of a point, and when the location information is configured for the wireless access device, the longitude and latitude acquired by the electronic device may be directly configured as the location information of the wireless access device to which the electronic device is currently connected. Furthermore, a specified radius range with the longitude and latitude acquired by the GPS module as a center point may be configured as the location information of the wireless access device.
It should be noted that, if the first wireless communication module of the electronic device is triggered to be started because the electronic device detects that the first wireless communication module is in the designated scene, the first wireless communication module may also be triggered to be turned off after the electronic device detects that the first wireless communication module is not in the designated scene, so as to save power. For example, the purpose of the electronic device starting the first wireless communication module is to facilitate receiving a directional data packet broadcast by the wireless access device and further updating the access password, and then when the electronic device detects that the first wireless communication module is started based on the detection of being in the designated scene, the electronic device and the wireless access device successfully establish a communication connection, and then the first wireless communication module may be closed.
As one way, a configuration file may be established in the electronic device for storing the activation origin of the first wireless communication module. It is understood that the first wireless communication module in the electronic device may be automatically activated after the electronic device is activated, may be activated in response to a user operation, or may be activated after some other event is detected. The electronic device may suggest a variable parameter in the configuration file to identify the cause of activation of the first wireless communication module. For example, if the variable value is 1, the first wireless communication module is characterized as being started with the electronic device. If the variable value is 2, the first wireless communication module is characterized to be started for manual operation of a user. If the variable value is 3, the first wireless communication module is characterized to be started in response to a specific event and needs to be shut down after the event is ended. In this case, after the access password acquired based on the first wireless communication mode successfully establishes a communication connection with the wireless access device in the second communication mode, the electronic device may query the variable value in the local foregoing configuration file, and if the variable value is 3, the first wireless communication module may be turned off.
Step S120: and acquiring the updated access password from the directional data packet.
It should be noted that, in the process of generating the directional data packet, the wireless access device not only increases the identifier of the electronic device of the directional broadcast, but also increases the updated access password.
Taking bluetooth ble mode as an example, the wireless access device may broadcast the data packet based on the ble mode.
In the format of the data packet shown in the above table, a field with a name of Length is used for representing the Length of the data packet, a field with a name of Type represents the connection Type of the current data packet, a field with a name of MFG ID represents the ID of the manufacturer of the bluetooth module sending the data packet, a field with a name of iBeacon represents that the current data packet is generated based on the iBeacon mode, a field with a name of MD5 represents the device identifier carried by the data packet and encrypted based on the MD5 mode, and the field names Major, Minor and Ref are all used for carrying feature values to distinguish different data packets sent by the same device. It can be seen that the identification of the electronic device and the updated access password can be added at a 16Byte length field in the data packet shown in the above table. It should be noted that the packet format and the name of each field shown in the above table are only exemplary, and the packet format and the field name of the broadcast data transmitted by the wireless control device may also be changed according to the actually carried data.
Then in this manner, the step of obtaining the updated access password from the targeted data packet comprises: and reading the updated access password from the specified field in the received directional data packet.
Alternatively, the wireless access device encrypts the broadcasted access password by using a public key, and in this way, the electronic device may decrypt, based on a configured private key, encrypted data obtained from the directional data packet to obtain an updated access password, where the encrypted data is obtained by encrypting based on a public key corresponding to the private key.
Step S130: and replacing the locally stored access password with the updated access password, wherein the updated access password is used for access verification in the process that the electronic equipment establishes communication with the wireless access equipment based on the second communication mode.
It is to be understood that, before the replacing step is performed, the access password stored locally by the electronic device is used for access authentication during the process of establishing communication with the wireless access device based on the second communication mode before the electronic device performs the replacing action, and the updated access password is used for access authentication during the process of establishing communication with the wireless access device based on the second communication mode until the next replacing action is performed by the electronic device.
According to the data updating method, under the condition that the electronic equipment generally completes wireless access with the wireless access equipment based on the second wireless communication mode, the updated access password is obtained from the directional data packet which is broadcasted based on the first wireless communication mode and carries the identification of the electronic equipment, and then the locally stored access password is replaced by the updated access password. Therefore, after the access password in the wireless access equipment is updated, the electronic equipment can acquire the updated access password through the broadcast data packet sent by other communication modes, and further the user does not need to manually enter the updated password again, and the user experience is improved.
Referring to fig. 3, a data updating method provided in the embodiment of the present application is applied to an electronic device, and the method includes:
step S210: and acquiring a directional data packet broadcasted based on a first wireless communication mode, wherein the directional data packet carries the identifier of the electronic equipment.
Step S220: and acquiring the updated access password from the directional data packet.
Step S230: and replacing the locally stored access password with the updated access password, wherein the updated access password is used for access verification in the process that the electronic equipment establishes communication with the wireless access equipment based on the second communication mode.
Step S240: and returning a successful updating message to the wireless access equipment based on the first wireless communication mode, wherein the successful updating message is used for informing the wireless access equipment to stop broadcasting the directional data packet.
It can be understood that, during the broadcasting of the directional data packet, the wireless access device broadcasts the directional data packet for each of the electronic devices that have been successfully connected. Then, after completing the updating of the access password, a certain electronic device may perform feedback to the wireless access device, so that the wireless access device stops broadcasting the directional data packet of the wireless access device.
It should be noted that various electronic devices may be distributed in different areas, and the range of the signal broadcasted by the wireless access device through the first wireless communication mode may be relatively limited, which may cause the electronic device to be unable to receive the signal all the time. For example, in a home, the electronic devices may include a television, an air conditioner, a water heater, a refrigerator, and the like. In which the tv is located in the living room, the air conditioner is located in the bedroom, the water heater is located in the kitchen, the refrigerator may also be located in the kitchen, and the wireless access device may be located in the living room, which may result in only the tv receiving the broadcast signal. For example, if the first communication method is a bluetooth ble method, the second communication method is a WiFi communication method. In this case, because the transmission power of the bluetooth ble communication mode is low and the penetrability is not good, the directional data packet sent by the wireless access device through the bluetooth ble communication mode may only be transmitted within the range of the living room, and although the electronic device outside the living room may still receive the WiFi signal sent by the wireless access device, the WiFi connection still cannot be completed because of the updated access password that cannot be obtained.
In order to facilitate that electronic devices distributed at different locations can acquire the updated access password as soon as possible, as one mode, the electronic device receiving the updated access password can serve as an intermediary device to start sending broadcast data packets based on the first wireless communication mode. Optionally, the electronic device may perform device scanning in the first wireless communication mode, and then perform directional packet transmission based on the scanned other electronic devices.
For example, as shown in fig. 4, a wireless access device 99 and an electronic device 97 and an electronic device 96 are included, where the electronic device 97 may be a smart phone, and the electronic device 96 may be a television. It is understood that the electronic device 97 is within the wireless signal coverage range of the wireless access device 99 based on the first communication mode (the range indicated by the large-range dashed line in the figure), and the electronic device 96 is not within the wireless signal coverage range of the wireless access device 99 based on the first communication mode. However, both the electronic device 97 and the electronic device 96 are within a range of a wireless signal transmitted by the wireless access device 99 based on the second communication method (a range indicated by a solid line in the figure). In this case, even if the wireless access device 99 broadcasts the directional data packet corresponding to the electronic device 96, the electronic device 96 still cannot receive the directional data packet, and the electronic device 96 cannot receive the updated access password. In this scenario, after the locally stored access password is replaced with the updated access password, as a manner, the electronic device 97 may not immediately close the first wireless communication module, but search whether there is another electronic device nearby that needs to access the network through the wireless access device 99, and then may search the electronic device 96, and then the electronic device 97 may continue to send a directional data packet corresponding to the electronic device 96 through the first wireless communication module, so that the electronic device 96 may also acquire the updated access password in time.
Optionally, for the electronic device that directly receives the broadcast from the wireless access device, the electronic device with the management authority may continue to broadcast the directional data packet to other electronic devices. For example, a smartphone or tablet of a typical user may be the electronic device with administrative privileges. The electronic device with administrative privileges may view the electronic device that has successfully established a communication connection with the wireless access device.
For example, as shown in fig. 5, the electronic device with management authority may display a device management interface shown in fig. 5, and the name of the electronic device that has been successfully connected in the history and the currently corresponding connection relationship may be displayed in the device management interface. For example, if the object-tv set has successfully established a connection with the wireless access device, it is in an on-line state, and if the master-bedroom air conditioner has not successfully established a connection with the wireless access device, it is in an off-line state. Based on the mode, the user can hold the electronic device with the management authority close to the electronic device in the offline state (possibly, the electronic device is not in the broadcast signal coverage range sent by the wireless access device based on the first wireless communication mode), so that the electronic device in the offline state can also acquire the updated access password in time, and the user does not need to manually configure the electronic device which is not in the broadcast signal coverage range sent by the wireless access device based on the first wireless communication mode to acquire the updated access password.
According to the data updating method, under the condition that the electronic equipment generally completes wireless access with the wireless access equipment based on the second wireless communication mode, the updated access password is obtained from the directional data packet which is broadcasted based on the first wireless communication mode and carries the identification of the electronic equipment, and then the locally stored access password is replaced by the updated access password. Therefore, after the access password in the wireless access equipment is updated, the electronic equipment can acquire the updated access password through the broadcast data packet sent by other communication modes, and further the user does not need to manually enter the updated password again, and the user experience is improved. And after the access password is updated, sending feedback information to the wireless access equipment so that the wireless access equipment can stop broadcasting the directional data packet corresponding to the current electronic equipment in time.
Referring to fig. 6, a data updating method provided in an embodiment of the present application is applied to a third-party client in an electronic device, and the method includes:
step S310: and acquiring a directional data packet broadcasted based on a first wireless communication mode, wherein the directional data packet carries the identifier of the electronic equipment.
Step S320: and acquiring the updated access password from the directional data packet.
Step S330: and storing the updated access password in a specified area, wherein the specified area is different from a storage area for storing the access password by a target system application, and the target system application is a program for managing the electronic equipment to communicate based on the second communication mode.
It should be noted that, in one mode, the wireless access password in the electronic device is stored in a system file. For example, if the electronic device is an android operating system-based electronic device, the access password may be stored in data \ misc \ wifi \ wpa _ supplicant. However, if the method provided in this embodiment is executed by the third-party client, the third-party client cannot operate the file storing the access password when the third-party client does not acquire the system permission, for example, the root permission. In this manner, the third party client may first store the acquired updated access password in its storage area with operating rights.
Step S340: when it is detected that the target system application in the electronic equipment displays an access password input interface, the updated access password stored in the designated area is transmitted to the target system application, so that the target system application fills the updated access password into the access password input interface to replace the locally stored access password, and automatically controls the electronic equipment to establish communication connection with the wireless access equipment through a second communication mode based on the updated access password.
As a manner, the target system application may broadcast the system message after starting, for example, when displaying the access password input interface, for example, the system message broadcast may be performed based on the content provider, and then after receiving the system message, the third party client may return the stored updated access password in the designated area to the target system application in a process communication manner, so that the target system application fills the updated access password in the access password input interface to replace the locally stored access password.
Optionally, as shown in fig. 7, an automatic update button is configured on the key input interface of the target system application, and when it is detected that the update button is touched, the target system application may start broadcasting the foregoing system message.
According to the data updating method, under the condition that the electronic equipment generally completes wireless access with the wireless access equipment based on the second wireless communication mode, the directional data packet which is broadcasted based on the first wireless communication mode and carries the identifier of the electronic equipment can be obtained through the third-party client side in the electronic equipment, and then the updated access password is obtained from the directional data packet. And under the condition that the third-party client does not have the authority of editing the system file, the updated access password stored in the designated area can be transmitted to the target system application in a process communication mode, so that the target system application fills the updated access password into the access password input interface to replace the locally stored access password, and automatically controls the electronic equipment to establish communication connection with the wireless access equipment in a second communication mode based on the updated access password, so that the user does not need to manually enter the updated password again, and the user experience is improved.
Referring to fig. 8, a data updating method provided in an embodiment of the present application is applied to a wireless access device, and the method includes:
step S410: and the wireless access equipment acquires an updated access password, and the updated access password is used for access verification in the process of establishing communication between the electronic equipment and the wireless access equipment based on a second communication mode.
Step S420: broadcasting a directional data packet based on a first wireless communication mode, wherein the directional data packet carries an identifier of corresponding electronic equipment and the updated access password, and the identifier is used for the electronic equipment to receive the directional data packet and obtain the updated access password from the directional data packet.
As a mode, the wireless access device encrypts the updated access password based on a public key acquired from the electronic device in advance to obtain encrypted data; generating a directional data packet carrying the encrypted data and the identifier of the electronic equipment; broadcasting the directional data packet.
It should be noted that, after establishing a communication connection with the wireless access device, the electronic device may establish a protocol connection with a Server running in the wireless access device, for example, the third party Client, based on a Client/Server mechanism, and then send the generated public key to the wireless access device.
