Detailed Description
The following description of the embodiments of the present application will be made clearly and completely with reference to the accompanying drawings, in which it is apparent that the embodiments described are only some embodiments of the present application, but not all embodiments. All other embodiments, which can be made by those skilled in the art based on the embodiments of the application without making any inventive effort, are intended to be within the scope of the application.
With the continuous development of the internet of things technology and communication technology, besides smart phones, tablet computers and other devices, more electronic devices have the capability of accessing to a network. For example, smart meters, door sensors, body sensors, door and window sensors, temperature and humidity sensors, water logging sensors, natural gas alarms, smoke alarms, wall switches, wall sockets, smart sockets, wireless switches, wireless wall mount switches, curtain motors, multifunctional gateways, air conditioning partners, projectors, projection screens, smart curtain motors, smart speakers, cameras, and other electronic devices.
The electronic device can be accessed into the network through the wireless access device in the process of accessing the network. Specifically, the electronic device may send an access request to the wireless device after scanning within 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, the electronic equipment can perform data interaction with the router, and then access to the network through the router. The electronic device can acquire the access password by triggering the user to input through the input interface, and can also directly read the access password input by the locally stored user history.
The inventors have found in research that the access codes stored in the wireless access devices are sometimes changed. After the access password configured in the wireless access device is changed, other electronic devices must also use the changed access password to perform authentication to establish communication connection with the wireless access device. The modification operation of the access password used by other electronic devices must be performed manually by a user, which causes great inconvenience to the user. In addition, when there are too many devices that need to perform access password update, more inconvenience is brought to the user.
Accordingly, the inventors have proposed a data updating method, apparatus, and electronic device in the present application that can improve the above-described problems. 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, so that the user is not required to manually re-enter the updated password, and the user experience is improved.
An environment in which embodiments of the present application may operate is described below.
As shown in fig. 1, in the operating environment shown in fig. 1, the wireless access device 99 may transmit a broadcast signal based on the second communication manner. Wherein the dashed line characterizes the coverage of its broadcast signal. And an electronic device in the coverage area of its broadcast signal may receive the data packet carried by the broadcast signal. For example, electronic device 98 and electronic device 97 in the figures. 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 identity of the electronic device to the broadcast signal, thereby implementing broadcasting the directed data packet. For a directional data packet, only the electronic device corresponding to the directional data packet can be actually acquired, and for the electronic device not corresponding to the directional data packet, the electronic device corresponding to the directional data packet is discarded even after receiving the data packet. It can be understood that the electronic device represented by the identifier of the electronic device carried in the directional data packet is the electronic device corresponding to the directional data 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 by an embodiment of the present application is applied to an electronic device, and the method includes:
step S110: and acquiring a directional data packet broadcast based on the 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 a target receiving device of the directional data packet.
It should be noted that, both the electronic device and the wireless access device may support multiple communication modes. For example, both the first communication mode and the second communication mode may be supported. In the embodiment of the application, the second communication mode is a communication mode adopted by the wireless access device for realizing wireless access of the electronic device. Wherein, the wireless access of the electronic device refers to the electronic device accessing the public network resource through the wireless access device. 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 a WiFi-based communication mode. After the wireless access device acquires the updated access code, in order to facilitate the electronic device to acquire the updated access code, the wireless access device will be based on the directional data packet broadcasted by the first wireless communication mode.
It can be appreciated that the directional data packet broadcast by the wireless access device can be obtained if the electronic device is within the coverage area of the wireless access device based on the broadcast signal of the second wireless communication mode. In the actual operation process of the electronic device, in order to achieve the effect of saving electric quantity, the electronic device does not start the first wireless communication module based on the communication of the first wireless communication mode in real time.
Then, as one way, the electronic device may trigger the first wireless communication module to be started when detecting the specified scene, so that the electronic device receives, through the first wireless communication module, the data packet sent based on the first wireless communication way.
In the embodiment of the application, the electronic device can detect whether the electronic device is in the specified scene or not in a plurality of ways.
Wherein, as one way, when detecting that the communication connection between the wireless access device and the access password based on the local storage is failed to be established based on the second communication way, the method is judged to be in the appointed scene.
It will be appreciated that if the electronic device has established a communication connection with the wireless access device, during which process the communication connection that has been established between the electronic device and the wireless access device will be broken if the access password corresponding to the wireless access device is updated. For the electronic device, after the first wireless module is started, the connection is automatically performed for the wireless access device which is successfully connected in history. In this case, the electronic device is always in a failed state in the process of establishing a communication connection with the wireless access device based on the locally stored access password and the second communication mode, because the access password corresponding to the wireless access device has been updated. In order to facilitate the electronic device to quickly and automatically acquire the updated access password after the access password of the wireless access device is updated, the electronic device may trigger to start the first wireless communication module when the communication connection between the access password based on the local storage and the wireless access device based on the second communication mode fails, so as to receive the directional data packet broadcast by the wireless access device based on the first wireless communication mode.
Further alternatively, when the electronic device detects that the wireless access device is within a specified location range, it is determined 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 through configuring the positioning module. For example, optionally, when the positioning module is a GPS module, the electronic device may acquire the longitude and latitude as the location information through the GPS module. Correspondingly, the electronic equipment can also store the position information of the wireless access equipment. Alternatively, the electronic device may acquire current location information of itself as location information of the wireless access device that has been connected at present after establishing communication connection with the wireless access device. In this case, the electronic device may periodically acquire the current location information of the electronic device, and then compare the current location information with the location information of the locally stored wireless access device that is historically connected, and if the electronic device detects that the electronic device is within the specified location range of a certain wireless access device, it determines that connection may be established with the wireless access device, so that the first wireless communication module may be started in advance, so that an updated access password may be timely acquired.
It should be noted that, in general, the location information obtained through the GPS module is the longitude and latitude of a point, and when the location information is configured for the wireless access device, the longitude and latitude obtained through 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, the specified radius range with the longitude and latitude as the center point acquired by the GPS module may be configured as the position 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 electronic device is in the specified scene, the electronic device may trigger to close the first wireless communication module after detecting that the electronic device is not in the specified scene, so as to save electric quantity. For example, the electronic device may start the first wireless communication module to facilitate receiving the directional data packet broadcast by the wireless access device, and further update the access password, so when the electronic device detects that the electronic device successfully establishes a communication connection with the wireless access device after starting the first wireless communication module based on detecting that the electronic device is in the specified scene, the electronic device may close the first wireless communication module.
As one way, a configuration file may be established in the electronic device for storing the start-up cause of the first wireless communication module. It will be appreciated that the first wireless communication module in the electronic device may be automatically activated upon activation of the electronic device, may be activated in response to a user operation, or may be activated upon detection of some other event. The electronic device may suggest a variable parameter in the configuration file to identify the start-up cause of the first wireless communication module. For example, if the variable value is 1, the first wireless communication module is characterized as being activated with the electronic device. If the variable value is 2, the first wireless communication module is characterized as being manually activated by the user. If the variable value is 3, then the first wireless communication module is characterized as being activated in response to a particular event and needs to be turned off after the event has ended. In this case, the electronic device may query the variable value in the local configuration file after the access password acquired based on the first wireless communication manner is successfully connected to the wireless access device in the second communication manner, and if the variable value is 3, may close the first wireless communication module.
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 may not only increase the identifier of the electronic device that is broadcast in the direction, but also increase the updated access password.
Taking bluetooth ble mode as an example, the wireless access device may broadcast data packets based on the ble mode.
In the format of the data packet shown in the table, a Length field is used for representing the Length of the data packet, a field with the name of Type represents the connection Type of the current data packet, a field with the name of MFG ID represents the ID of the manufacturer of the Bluetooth module for transmitting the data packet, a field with the name of iBeacon represents the current data packet generated based on the iBeacon mode, a field with the name of MD5 represents the device identifier encrypted based on the MD5 mode and carried by the data packet, and field names Major, minor and Ref are all used for carrying characteristic values so as to distinguish different data packets transmitted by the same device. It can be seen that the identification of the electronic device and the updated access password can be added at the field of 16Byte length 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 data actually carried.
In this way, the step of obtaining the updated access code from the directional packet comprises: and reading the updated access password from a specified field in the received directional data packet.
Alternatively, the wireless access device encrypts the broadcasted access code using a public account, and in this way, the electronic device may decrypt the encrypted data obtained from the directional data packet based on the configured private key, to obtain an updated access code, where the encrypted data is obtained by encrypting the encrypted data based on the 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 performing access verification in the process that the electronic equipment establishes communication with the wireless access equipment based on a second communication mode.
It will be appreciated that the access code stored locally by the electronic device is used for access verification during communication with the wireless access device based on the second communication means before the electronic device performs the replacing step, and the updated access code is used for access verification during communication with the wireless access device based on the second communication means after the electronic device performs the replacing action until the next replacing step.
According to the data updating method provided by the application, under the condition that the electronic equipment is generally in wireless access with the wireless access equipment based on the second wireless communication mode, the access password after updating can be obtained from the directional data packet by obtaining the directional data packet which is broadcast based on the first wireless communication mode and carries the identification of the electronic equipment, and then the access password stored locally is replaced by the access password after updating. 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, so that the user is not required to manually re-enter the updated password, and the user experience is improved.
Referring to fig. 3, a data updating method provided by an embodiment of the present application is applied to an electronic device, and the method includes:
step S210: and acquiring a directional data packet broadcast based on a first wireless communication mode, wherein the directional data packet carries the identification 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 performing access verification in the process that the electronic equipment establishes communication with the wireless access equipment based on a second communication mode.
Step S240: and returning a message of successful update to the wireless access equipment based on the first wireless communication mode, wherein the message of successful update is used for notifying the wireless access equipment to stop broadcasting the directional data packet.
It can be appreciated that, in the process of broadcasting the directional data packet, the wireless access device will broadcast the directional data packet for all the successfully connected electronic devices. When a certain electronic device completes updating the access password, the electronic device can feed back 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 broadcast by the wireless access device through the first wireless communication manner may be limited, which may cause the electronic device to not receive the signal. For example, in a household, the electronic device may include a television, an air conditioner, a water heater, a refrigerator, and the like. The television is arranged in a living room, the air conditioner is arranged in a bedroom, the water heater is arranged in a kitchen, the refrigerator is possibly arranged in the kitchen, and the wireless access equipment is possibly arranged in the living room, so that only the television can receive the broadcast signals. For example, if the first communication mode is bluetooth ble mode and the second communication mode is WiFi communication mode. In this case, because the transmitting power of the bluetooth ble communication mode is low and the penetrability is poor, the directional data packet sent by the wireless access device through the bluetooth ble communication mode may only be transmitted in the living room range, 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 the electronic devices distributed in different positions can acquire the updated access password as soon as possible, as a way, the electronic device receiving the updated access password can serve as an intermediary device, and starts to send the broadcast data packet based on the first wireless communication way. Alternatively, the electronic device may perform device scanning through the first wireless communication manner, and then perform transmission of the directional data packet based on the other scanned electronic device.
For example, as shown in fig. 4, a wireless access device 99, 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 will be appreciated that the electronic device 97 is within the wireless signal coverage of the wireless access device 99 based on the first communication mode (the range shown by the larger dashed line in the figure), while the electronic device 96 is not within the wireless signal coverage of the wireless access device 99 based on the first communication mode. However, the electronic apparatus 97 and the electronic apparatus 96 are both within the range of the wireless signal transmitted by the wireless access apparatus 99 based on the second communication method (the range shown by the 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 cannot receive the directional data packet, which causes the electronic device 96 to not receive the updated access code. In this scenario, after replacing the locally stored access password with the updated access password, the electronic device 97 may search whether other electronic devices needing to access the network through the wireless access device 99 exist nearby instead of immediately closing the first wireless communication module, and further search the electronic device 96, and then the electronic device 97 may continue to send the 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 an electronic device directly receiving the broadcast of 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 typical user's smart phone or tablet may be used as the electronic device with administrative rights. An electronic device with administrative rights may view an electronic device that has successfully established a communication connection with a wireless access device.
For example, as shown in fig. 5, the electronic device having the management authority may display the device management interface shown in fig. 5, and the name of the electronic device that has been successfully connected in history and the current corresponding connection relationship may be displayed in the device management interface. For example, an object-tv set therein has successfully established a connection with a wireless access device, then it is in an on-line state, while a main-air conditioner therein has not successfully established a connection with a wireless access device, then it is in an off-line state. In this way, the user can hold the electronic device with the management authority close to the electronic device in the offline state (possibly the device not in the coverage area of the broadcast signal sent by the wireless access device based on the first wireless communication mode), so that the electronic device in the offline state can also timely acquire the updated access password, and the user does not need to manually configure the electronic device not in the coverage area of the broadcast signal 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 provided by the application, under the condition that the electronic equipment is generally in wireless access with the wireless access equipment based on the second wireless communication mode, the access password after updating can be obtained from the directional data packet by obtaining the directional data packet which is broadcast based on the first wireless communication mode and carries the identification of the electronic equipment, and then the access password stored locally is replaced by the access password after updating. 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, so that the user is not required to manually re-enter the updated password, and the user experience is improved. And after the access password is updated, a feedback message is sent to the wireless access device, so that the wireless access device stops broadcasting the directional data packet corresponding to the current electronic device in time.
Referring to fig. 6, an embodiment of the present application provides a data updating method, which is applied to a third party client in the electronic device, and includes:
step S310: and acquiring a directional data packet broadcast based on a first wireless communication mode, wherein the directional data packet carries the identification 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 into a designated area, wherein the designated area is different from a storage area in which the access password is stored 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.
In one embodiment, the wireless access code in the electronic device is stored in a system file. For example, if the electronic device is an electronic device based on an android operating system, the access password may be stored in data\risc\wifi\wpa_supplicant. 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 without obtaining the system authority, for example, root authority.
In this way, the third party client may first store the acquired updated access password in a storage area where it has operating rights.
Step S340: when the target system application in the electronic equipment is detected to display 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 the electronic equipment is automatically controlled to establish communication connection with the wireless access equipment in a second communication mode based on the updated access password.
As a way, after the target system application may broadcast a system message, for example, when an access password input interface is displayed, for example, system message broadcast may be performed based on content provider, and after the foregoing third party client receives the system message, the foregoing third party client may return the stored updated access password in the designated area to the target system application in a manner of communicating through a process, so that the target system application fills the updated access password into 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 the update button is detected to be touched, the target system application may start broadcasting the aforementioned system message.
According to the data updating method provided by the application, under the condition that the electronic equipment is generally in wireless access with the wireless access equipment based on the second wireless communication mode, a directional data packet which is broadcast based on the first wireless communication mode and carries the identification of the electronic equipment can be acquired through a third party client in the electronic equipment, and then an updated access password is acquired 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, and further, the user is not required to manually re-enter the updated password, and the user experience is improved.
Referring to fig. 8, a data updating method provided by an embodiment of the present application is applied to a wireless access device, and the method includes:
step S410: the wireless access device acquires an updated access password, and the updated access password is used for performing access verification in the process that the electronic device establishes communication with the wireless access device based on a second communication mode.
Step S420: based on a first wireless communication mode, broadcasting a directional data packet, wherein the directional data packet carries an identifier of a corresponding electronic device and the updated access password, and the identifier is used for the electronic device to receive the directional data packet and acquire the updated access password from the directional data packet.
As one way, the wireless access device encrypts the updated access password based on a public key obtained in advance from the electronic device, to obtain encrypted data; generating a directional data packet carrying the encrypted data and the identification of the electronic equipment; broadcasting the directional data packet.
It should be noted that, after the electronic device may establish a communication connection with the wireless access device, a Client running on the electronic device, for example, the aforementioned third party Client, may establish a protocol connection with a Server running on the wireless access device based on a Client/Server mechanism, and then send the generated public key to the wireless access device.
As one mode, the wireless access device acquires a target electronic device, wherein the target electronic device is an electronic device which is successfully connected with the wireless access device based on the second wireless communication mode;
and broadcasting the directional data packets corresponding to the target electronic devices respectively based on a first wireless communication mode.
It should be noted that, as a broadcasting method, the wireless access device may broadcast the directional data packets corresponding to different electronic devices in a time division manner. For example, the electronic devices that need to broadcast the directional packet are electronic device a, electronic device B, and electronic device C, respectively. The wireless access device may divide the time into three sequential time slices during a transmission period, broadcast the directional data packet corresponding to the electronic device a during the first time slice, broadcast the directional data packet corresponding to the electronic device B during the second time slice, and broadcast the directional data packet corresponding to the electronic device C during the third time slice. Further, if the electronic device has fed back that the access password has been updated, the electronic device may correspondingly update the time slices in a sending period, so that the number of updated time slices is the same as the number of electronic devices to be subjected to the directional data packet broadcast. For example, if the wireless access device has received the information that the wireless access password fed back by the electronic device B is updated successfully, the wireless access device may remove the time slice originally allocated to the electronic device B, and further allocate a transmission period to two time slices, so as to respectively transmit the directional data packets corresponding to the electronic device a and the electronic device C.
In addition, when the wireless access device broadcasts the directional data packet based on the first wireless communication mode, the electronic device which is often connected can be selectively used as an object for broadcasting the directional data packet. For example, an electronic device having a connection record every day of the history for a week may be the subject of a broadcast targeting packet.
