The embodiment of the present application can be applied to the network structure diagram shown in FIG. 1a. In the prior art, the smart terminal and the Wi-Fi access point in the architecture need to establish a connection through the authentication connection process of the standard Wi-Fi protocol. After that, data can be transferred.

The authentication connection process of the smart terminal and the Wi-Fi access point through the standard Wi-Fi protocol is as shown in FIG. 1b, and the smart terminal broadcasts a probe request, which includes the data of the smart terminal itself, when the Wi-Fi access point receives After the probe request, the smart terminal is fed back a probe response.

Data interaction can be performed after the ingress establishes a connection.

It should be noted that the Wi-Fi access point may be a device supporting the IEEE 802.11 standard, such as a wireless router, a wireless repeater, a wireless network card, a mobile phone Wi-Fi, and other devices with a built-in Wi-Fi module.

As shown in FIG. 2, the embodiment of the present application provides an information transmission method, including the following steps:

201. The smart terminal establishes a connection with the Wi-Fi access point.

When the smart terminal establishes a connection with the Wi-Fi access point for the first time in the initial state, it first needs to wake up the smart terminal and the Wi-Fi access point, and then the smart terminal and the Wi-Fi access point pass the standard Wi-Fi. The authentication connection process of the protocol establishes a connection.

It should be noted that the main purpose of establishing a connection between the smart terminal and the Wi-Fi access point in the initial state is that the smart terminal completes device registration and service registration at the Wi-Fi access point end, so that the smart terminal and the Wi-Fi connection are connected. When the in-point is disconnected, the Wi-Fi access point can confirm the identity of the smart terminal according to the registration information of the smart terminal at the Wi-Fi access point.

It should be noted that the smart terminal completes device registration and service registration at the Wi-Fi access point end, that is, the smart terminal information and service information of the smart terminal need to be recorded on the Wi-Fi access point side, where the service information indicates the smart terminal. The type of information transmitted to the Wi-Fi access point.

For example, when User A newly installs a smoke alarm (smart terminal) with a built-in Wi-Fi module at home, User A first needs to establish a connection between the smoke alarm and the home router (Wi-Fi access point).

202. The smart terminal sends the first information to the Wi-Fi access point.

When the smart terminal establishes a connection with the Wi-Fi access point in the initial state, that is, when the smart terminal and the Wi-Fi access point establish a connection for the first time, the smart terminal sends the first information to the Wi-Fi access point. The first information includes the registration information for the smart terminal device registration and the public key of the smart terminal, wherein the registration information may include the form information of the smart terminal and the hardware address MAC of the smart terminal, where the smart terminal The public key is used to verify the identity and legality of the smart terminal by the subsequent Wi-Fi access point. The shape information of the smart terminal carries information such as the shape and size of the smart terminal.

203. The Wi-Fi access point records the first information.

After the first information is received by the Wi-Fi access point, the first information is recorded, and the device registration and service registration of the smart terminal at the Wi-Fi access point end is completed, so that the smart terminal and the Wi-Fi access point are succeeded. After disconnecting, the Wi-Fi access point verifies the identity and legality of the smart terminal based on the first information recorded.

204. The Wi-Fi access point sends an encryption key to the smart terminal.

The Wi-Fi access point can randomly generate an encryption key, and the Wi-Fi access point itself records the encryption key, and then sends the encryption key to the smart terminal. After receiving the encryption key, the smart terminal receives the encryption key. The encryption key will be recorded so that the status indication information can be encrypted later using the encryption key.

205. The smart terminal is disconnected from the Wi-Fi access point.

After the smart terminal and the Wi-Fi access point complete steps 202 to 204, and the smart terminal and the Wi-Fi access point have no information transmission, the smart terminal and the Wi-Fi access point are disconnected, and the smart terminal enters the sleep state. status.

It should be noted that the smart terminal and the Wi-Fi access point may automatically disconnect after the smart terminal and/or the Wi-Fi access point detects that the information transmission is completed, and may also disconnect using other methods, for example, by using the user. Manual disconnection, the specific way to disconnect is not limited here.

206. The smart terminal wakes up its own Wi-Fi module.

After the smart terminal disconnects from the Wi-Fi access point, when the smart terminal senses an event that needs to be reported within the detection range, and the Wi-Fi module is in a sleep state, the smart terminal wakes up itself to send information. The included Wi-Fi module.

For example, User A is not at home. At this time, the child in User A's home is playing with fire. At this time, the smoke generated by the combustion exceeds a certain concentration, triggering the smoke alarm installed in User A's home, and the smoke alarm will wake up. Its own Wi-Fi module.

207. The smart terminal encrypts the status indication information according to the encryption key.

When the smart terminal senses an event that needs to be reported in the detection range, the status indication information is encrypted by using the previously saved encryption key, and the encrypted status indication information is obtained, wherein the status indication information and the sensed need to be reported. The event corresponds.

The event to be reported is related to the type of the smart terminal. For example, if the smart terminal is a smoke alarm, when the smoke alarm detects that the smoke concentration in the detection range exceeds a preset value, the report event is triggered. At this time, the reported event is that the smoke concentration exceeds the preset value.

208. The smart terminal sends the second information to the Wi-Fi access point.
