Detailed Description
In order to make the objects, technical solutions and advantages of the present invention more apparent, embodiments of the present invention will be described in detail with reference to the accompanying drawings.
the embodiment of the invention provides a network connection method of intelligent home equipment, which is used in an intelligent home gateway and is shown in figure 1, and the method comprises the following steps:
step 101: and detecting whether the configuration information of the intelligent home gateway changes.
In the embodiment of the present invention, the smart home device establishes a network connection with the smart home gateway through a network address allocated to the smart home gateway by the smart home gateway, that is, the smart home device establishes a network connection with the smart home gateway through a Dynamic Host Configuration Protocol (DHCP) service on the smart home gateway. For convenience of explanation, the function of the DHCP service will be briefly described: for the intelligent home gateway based on the DHCP service, when receiving a network connection request sent by the intelligent home equipment, the intelligent home gateway dynamically allocates a network address for the intelligent home equipment according to the configuration information of the intelligent home gateway so as to establish network connection with the intelligent home equipment. Therefore, the network address allocated by the intelligent home gateway to the intelligent home device is related to the configuration information of the intelligent home gateway. Therefore, in the embodiment of the present invention, in order to maintain the effective network connection between the smart home device and the smart home gateway, the smart home gateway needs to detect whether the configuration information of the smart home gateway changes, so as to take effective measures to avoid the network connection disconnection between the smart home device and the smart home gateway.
the configuration information of the smart home gateway includes, but is not limited to, a local area network address, such as an IP (Internet Protocol) address, a DNS (Domain Name System) server address of a local area network, a network address range of a DHCP service, and the like, and the network address range of the DHCP service is determined according to the local area network address of the smart home gateway. The network address allocated by the intelligent home gateway to the intelligent home device is a network address within a network address range of the DHCP service, and the network address allocated by the intelligent home gateway to the intelligent home device may be an IP (internet protocol) address or the like.
Specifically, the smart home gateway detects whether the configuration information of the smart home gateway changes, and can be implemented in the following two ways.
the first mode is as follows: and the intelligent home gateway detects whether the configuration information changes in real time. That is, a preset time duration is set in the smart home gateway, and the smart home gateway performs an operation of detecting whether the configuration information changes every time of the preset time duration.
it should be noted that, in order to enable the intelligent home gateway to detect that the configuration information of the intelligent home gateway changes in time when the configuration information of the intelligent home gateway changes, the preset time duration should not be too long, for example, the preset time duration may be 1s, 2s, or 5s, and the like.
The second mode is as follows: when the intelligent home gateway detects a modification instruction for the configuration information of the intelligent home gateway, whether the configuration information of the intelligent home gateway changes or not is judged.
in the second mode, the intelligent home gateway does not need to detect whether the configuration information of the intelligent home gateway changes in real time, but when a modification instruction for the configuration information of the intelligent home gateway is detected, whether the configuration information really changes is judged. That is, when a user modifies the configuration information of the intelligent home gateway through a computer or other terminal, the intelligent home gateway detects a modification instruction for the configuration information, and when the intelligent home gateway detects the modification instruction, whether the configuration information of the intelligent home gateway changes or not can be judged by running a specified script program. The appointed script program is used for judging whether the configuration information of the intelligent home gateway really changes. Whether the configuration information of the intelligent home gateway changes or not is detected through the second mode, and the efficiency of detecting whether the configuration information changes or not by the intelligent home gateway can be improved.
it should be noted that, in the embodiment of the present invention, the intelligent home gateway establishes network connection with the intelligent home device through a DHCP service. Therefore, when the smart home gateway detects that the configuration information of the smart home gateway changes, in order to ensure that the smart home device can reestablish the network connection with the smart home gateway, the smart home gateway further needs to detect whether the DHCP service is set to be disabled.
Specifically, when the intelligent home gateway detects that the DHCP service is set to be disabled, prompt information is generated, where the prompt information is used to prompt that after the DHCP service is set to be disabled, the at least one intelligent home device cannot establish a network connection with the intelligent home gateway. When receiving a disable setting cancel instruction according to the prompt message, canceling the disable setting for the DHCP service, and then performing the operation in step 102; when receiving the continue disable setting instruction, the prompt message is ignored, and the DHCP service is still set to disable.
in a possible implementation manner, when the smart home gateway generates the prompt message, the prompt message further includes two options of "cancel disable" and "continue disable", and when the smart home gateway detects a trigger operation for the "cancel disable" option according to the prompt message, that is, when a cancel disable setting instruction is received, the disable setting for the DHCP service is cancelled, and then the operation in step 102 is executed. When the intelligent home gateway detects the trigger operation aiming at the 'continue forbidding' option, the intelligent home gateway determines that a continue forbidding setting instruction is received, and ignores the prompt message to enable the DHCP service to be still set to be forbidden.
step 102: when detecting that the configuration information of the intelligent home gateway changes, sending a notification message to at least one piece of intelligent home equipment which is currently in network connection with the intelligent home gateway, wherein the notification message is used for notifying the at least one piece of intelligent home equipment of the change situation of the configuration information of the intelligent home gateway, so that the at least one piece of intelligent home equipment can reestablish network connection with the intelligent home gateway according to the changed configuration information.
When detecting that the configuration information of the smart home gateway changes, in order to enable the smart home device connected with the smart home gateway to know that the configuration information of the smart home gateway changes, the smart home gateway needs to send a notification message to the smart home device. That is, the smart home gateway sends a notification message to the at least one smart home device, and when the at least one smart home device receives the notification message, it is determined that the configuration information of the smart home gateway accessed by the at least one smart home device changes.
in the embodiment of the present invention, the smart home gateway may send the notification message to the at least one smart home device in a broadcast manner, may also send the notification message in a multicast manner, or may send the notification message in a unicast manner. When the intelligent home gateway sends the notification message in a broadcasting mode, the notification message also carries the network address range of the DHCP service of the intelligent home gateway, when the intelligent home device receives the notification message sent in the broadcasting mode, the network address of the intelligent home device is compared with the network address range of the DHCP service of the intelligent home gateway, when the network address of the intelligent home device is determined to be in the network address range of the DHCP service of the intelligent home gateway, the configuration information of the intelligent home gateway accessed by the intelligent home gateway is determined to be changed according to the received notification message, and otherwise, no processing is performed. When the intelligent home gateway sends the notification message in a multicast mode, the intelligent home gateway determines the network address allocated by the intelligent home gateway to the at least one intelligent home device in advance, and then sends the notification message to the at least one intelligent home device at the same time. When the intelligent home gateway sends the notification message in a unicast mode, after the network address allocated to the at least one intelligent home device by the intelligent home gateway is determined, the notification message is sent to one of the intelligent home devices in a unicast mode according to the network address of the at least one intelligent home device, and when the feedback message sent by the intelligent home device is received, the notification message is sent to the next intelligent home device until the notification message is sent to each intelligent home device in the at least one intelligent home device.
Optionally, the notification message may also carry configuration information of the changed intelligent home gateway, and when the intelligent home device receives the notification message, it is determined that the configuration information of the intelligent home gateway accessed by the intelligent home device changes according to the configuration information of the changed intelligent home gateway.
it should be noted that, when the smart home gateway sends the notification message in a multicast or unicast manner, the smart home gateway needs to determine the network address of the at least one smart home device first, and then sends the notification message to the at least one smart home device according to the network address of the at least one smart home device. However, the network address allocated by the smart home gateway to the at least one smart home device may already be stored in the smart home gateway, or the network address allocated by the smart home gateway to the at least one smart home device may not be stored in the smart home gateway. When the network address allocated by the smart home gateway to the at least one smart home device is stored in the smart home gateway, the smart home gateway may directly send the notification message to the at least one smart home device in a multicast or unicast manner according to the network address of the at least one smart home device. When the network address allocated by the intelligent home gateway for the at least one intelligent home device is not stored in the intelligent home gateway, the intelligent home gateway may obtain the network address of the at least one intelligent home device by sending a broadcast message. That is, the smart home gateway transmits a broadcast message for acquiring the network address of the at least one smart home device, and the broadcast message carries the network address range of the DHCP service of the smart home gateway, when the intelligent home equipment receives the broadcast message, judging whether the network address of the intelligent home equipment belongs to the network address in the network address range of the DHCP service of the intelligent home gateway or not, when the intelligent home equipment determines that the network address of the intelligent home equipment belongs to the network address in the network address range of the DHCP service of the intelligent home gateway, the intelligent home gateway sends network address reporting information to the intelligent home gateway, the network address reporting information carries the network address of the intelligent home device, and the network address reporting information is used for prompting the intelligent home gateway that the intelligent home device is one of the at least one intelligent home device. And when the intelligent home gateway receives the network address reporting information, determining the network address of the intelligent home equipment.
particularly, when the smart home gateway sends the notification message to the smart home device in a unicast manner, in order to ensure that the smart home device receives the notification message, the smart home gateway may further set a timing time after sending the notification message to the smart home device, and start timing. And when the timing time is up and the intelligent home gateway does not receive the feedback message sent by the intelligent home equipment, resending the notification message, recording the sending times, continuously executing the timing operation, and circularly executing the operation until the intelligent home gateway receives the feedback message sent by the intelligent home equipment or the sending times reaches the preset sending times. And when the sending times reach the preset sending times, if the intelligent home gateway still does not receive the feedback message, ignoring the intelligent home equipment.
The feedback message is used to indicate that the smart home gateway has received the notification message, and the preset sending times are preset sending times in the smart home gateway, where the preset sending times may be 3 times, 5 times, or 10 times, and the like. The timing time is set in the smart home gateway and can be 10s, 30s or 50s, and the like.
For example, the preset sending times is 3 times, the timing time is 10s, when the intelligent home gateway sends the notification message to the intelligent home device in a unicast mode, timing is started, when the timing time is up to 10s, the intelligent home gateway does not receive the feedback message, the notification message is sent to the intelligent home device again, and the operation is executed in a circulating mode until the sending times exceed 3 times or the intelligent home gateway receives the feedback message.
in the embodiment of the present invention, when the network address range of the DHCP service included in the configuration information of the smart home gateway changes, the network address range of the DHCP service after the change may intersect with the network address range of the DHCP service before the change, so that the network address of the smart home device may still be in the network address range of the DHCP service after the change, that is, the smart home device does not need to reestablish network connection with the smart home gateway. In the embodiment of the present invention, in order to avoid sending the notification message to the smart home devices that do not need to reestablish network connection, the smart home gateway may select, from the at least one smart home device, a smart home device whose network address does not belong to the network address range after the DHCP service is changed, and send the notification message to the selected smart home device. That is, after the smart home gateway determines the at least one smart home device, the network address allocated by the smart home gateway for the at least one smart home device is determined, and then the network address of the at least one smart home device is compared with the network address range after the DHCP service is changed, if the network address of the smart home device does not belong to the network address range after the DHCP service is changed, a notification message is sent to the smart home device, and accordingly, for the smart home devices whose network addresses are still within the network address range after the DHCP service is changed, the notification message does not need to be sent to the smart home devices.
step 103: when the at least one piece of intelligent home equipment receives the notification message, the configuration information of the intelligent home gateway is set to be changed configuration information, so that the changed configuration information becomes effective.
When the intelligent home gateway sends the notification message in a broadcast or multicast mode, after the intelligent home gateway sends the notification message, the at least one intelligent home device is defaulted to receive the notification message. When the intelligent home gateway sends the notification message to each intelligent home device in the at least one intelligent home device in a unicast mode, when the intelligent home device receives the notification message, the intelligent home device sends a feedback message to the intelligent home gateway. When the intelligent home gateway receives feedback messages sent by all the intelligent home devices in the at least one intelligent home device, it is determined that the at least one intelligent home device receives the notification message.
therefore, whether the notification message is sent in a broadcast manner or in a unicast manner, the smart home gateway may determine that the at least one smart home device receives the notification message. When the intelligent home gateway determines that the at least one intelligent home device receives the notification message, the configuration information of the intelligent home gateway is set to be changed configuration information so that the changed configuration information becomes effective, that is, when the intelligent home device establishes network connection with the intelligent home gateway again, the intelligent home gateway reallocates a network address for the intelligent home gateway according to the changed configuration information.
it should be noted that, in the embodiment of the present invention, when the smart home device receives the notification message, it is determined that the configuration information of the smart home gateway to which the smart home device is connected changes, and at this time, the smart home device may send a network connection request to the smart home gateway to reestablish a network connection with the smart home gateway. However, when the smart home gateway receives the network connection request, the process of sending the notification message to the at least one smart home device by the smart home gateway may not be completed. For example, when the smart home devices send the notification message in a broadcast or multicast manner, because distances between the smart home devices and the smart home gateway are different, when one of the smart home devices receives the notification message and sends a network connection request to the smart home gateway, there may be a case that the other smart home devices have not received the notification message; or, when the smart home gateway sends the notification message in a unicast manner, if the smart home device that has received the notification message first directly sends the network connection request to the smart home gateway, the smart home gateway may still execute an operation of sending the notification message to other smart home devices. That is, when the intelligent home gateway receives the network connection request, the intelligent home gateway does not set the configuration information of the intelligent home gateway to the changed configuration information, at this time, if the intelligent home gateway reestablishes the network connection with the intelligent home device, the network connection is still the network connection established according to the configuration information before the change, and when the changed configuration information becomes effective, the network connection is still invalid. In the embodiment of the present invention, the above-described situation can be avoided by the following two strategies.
In the first strategy, before the intelligent home gateway sends the notification message to the at least one intelligent home device, the DHCP service of the intelligent home gateway is closed, and after the intelligent home gateway sets the configuration information of the intelligent home gateway to the changed configuration information, the DHCP service of the intelligent home gateway is opened.
In the first strategy, before the configuration information of the smart home gateway is set as the changed configuration information, that is, before the changed configuration information becomes effective, the DHCP service of the smart home gateway is closed, and at this time, the smart home device cannot reestablish network connection with the smart home gateway. And when the changed configuration information takes effect, starting the DHCP service, and executing step 104 to ensure that the reestablishment of the network connection between the intelligent home equipment and the intelligent home gateway is executed after the changed configuration information takes effect.
and the second strategy is that after the intelligent home gateway sets the configuration information of the intelligent home gateway to the changed configuration information, a network connection reestablishment message is sent to the at least one intelligent home device, so that the at least one intelligent home device sends a network connection request to the intelligent home gateway to carry out network connection again.
in the second strategy, when the smart home device receives the notification message, the smart home device does not send the network connection request to the smart home gateway, but sends the network connection request to the smart home gateway when receiving the network connection reestablishment message sent by the smart home gateway. The network connection reestablishment message is sent to the smart home device after the smart home gateway determines that the at least one smart home device receives the notification message and sets the configuration information thereof to the changed configuration information. Therefore, through the second policy, it can also be ensured that the reestablishment of the network connection between the smart home device and the smart home gateway is performed after the changed configuration information becomes effective.
Step 104: and according to the changed configuration information, reestablishing network connection with the at least one intelligent household device.
In the embodiment of the present invention, when the at least one smart home device receives the notification message, it is determined that the configuration information of the smart home gateway accessed by the at least one smart home device changes, and in order to continue establishing network connection with the smart home gateway, the at least one smart home device needs to send a network connection request to the smart home gateway to obtain a network address allocated to the smart home gateway according to the changed configuration information, and reestablish network connection with the smart home gateway.
Specifically, for the two strategies in step 103, after the intelligent home gateway starts the DHCP service or after the intelligent home gateway sends a network connection reestablishment message, when a network connection request of the intelligent home device is received, the intelligent home gateway allocates a network address to the intelligent home device according to the changed configuration information, and after the intelligent home device receives the network address, the intelligent home device reestablishes the network connection with the intelligent home gateway according to the network address. Since the starting of the DHCP service or the sending of the network connection reestablishment message is performed after the changed configuration information becomes effective, the network address received by the smart home device is a network address allocated according to the changed configuration information, that is, an effective network address. After the changed configuration information takes effect, the intelligent home equipment can successfully establish network connection with the intelligent home gateway.
In the embodiment of the invention, when the change of the configuration information of the intelligent home gateway is detected, before the configuration information takes effect, the intelligent home gateway actively sends a notification message to at least one intelligent home device which is currently in network connection with the intelligent home gateway. Because the notification message is used for notifying the intelligent home devices of the change condition of the configuration information of the intelligent home gateway, when the at least one intelligent home device receives the notification message, the network connection with the intelligent home gateway can be reestablished according to the changed configuration information of the intelligent home gateway, and the network connection with the intelligent home gateway is established without manually starting the intelligent home device by a user, so that the network connection efficiency between the intelligent home devices and the intelligent home gateway is improved.
