step S202: determining target equipment from the plurality of equipment under the condition that the local area network has the plurality of equipment, wherein the target equipment is selected from the plurality of equipment according to a preset rule;
it should be noted that the target device has the best overall performance among the plurality of devices, and the specific performance is represented by: the ability to process data, the ability to receive data, the ability to store data.
In an exemplary embodiment, the plurality of devices may be located in one home, i.e., the local area network may be a home network.
In an exemplary embodiment, determining the target device from the plurality of devices may be accomplished by:
step S11: instructing each of the plurality of devices to send corresponding first device information to the cloud server, wherein the first device information at least includes: the system comprises a processor model, a memory capacity, a Wireless Fidelity (WIFI) module model, a WIFI module signal strength, a WIFI module power and a system version;

It should be noted that before the step S22 is executed, the target election policy needs to be sent to the first device, and then the first device may determine the score of each of the multiple devices according to the first formula, and determine the device with the highest score as the target device.
In an exemplary embodiment, a device which is successfully connected with the cloud server first in the plurality of devices may be determined as a target device, and then the target device directly obtains weather data from the cloud server, and sends the obtained weather data to other devices in the group of devices.
In an exemplary embodiment, when the elected target device is suddenly powered off or disconnected from the network, a target device may be reselected from the group of devices according to the electing method.
In one illustrative example, the plurality of devices may be ordered, a priority of each device may be determined, a device with a high priority may be determined as a target device, and a device with a next priority among the plurality of devices may be determined as the target device in case of sudden power failure or network outage of the target device. It should be noted that the higher the overall performance of the device with the higher priority.
Step S204: sending a first data request to a cloud server through the target device, and acquiring target meteorological data sent by the cloud server in response to the first data request;
in an exemplary embodiment, before sending the first data request to the cloud server through the target device, the following steps are further performed:
step S31: instructing each device in the group of devices to send a corresponding second data request to the target device, wherein the second data request is used for indicating the type of weather data required by each device;
it should be noted that the types of meteorological data include, but are not limited to, weather forecast, life meteorological index, air quality index, and the like.
Step S32: instructing the target device to construct a target data table according to the second data request corresponding to each device in the group of devices, wherein the target data table has the type of meteorological data required by each device in the plurality of devices;
in one exemplary embodiment, the target data table may be: device a needs weather forecast, device B needs a life weather index, and device C needs an air quality index. The plurality of devices includes: device a, device B, device C.
In an exemplary embodiment, the sending, by the target device, the first data request to the cloud server may be further implemented by: sending a first data request to a cloud server through the target device, wherein the first data request is used for requesting the cloud server to acquire target meteorological data, and the target meteorological data comprises all types of meteorological data recorded in the target data table.
It will be appreciated that the services provided by different devices will be different and thus the types of weather data required will be different, for example, some devices will only require the most basic weather forecast, some devices will only require the life weather index, etc. And then each device in a set of devices can send the type of weather data required by the device to the target device, so that the target device can obtain the data of the corresponding type from the cloud server in a targeted manner and send the data to the corresponding device.
Step S206: transmitting, by the target device, the target weather data to each device in a group of devices, wherein the group of devices includes other devices in the plurality of devices other than the target device.
In an exemplary embodiment, the step S206 may be implemented as follows:
step S41: determining, from the target data table, a type of meteorological data required for each device in the set of devices;
step S42: transmitting, by the target device, weather data of the type required by each device of the set of devices in the target weather data to each device of the set of devices.
That is, after acquiring the target meteorological data, the target device sends the meteorological data of the type required by each device in a set of devices in the target meteorological data to each device in the set of devices according to the target data table. For example: the second request sent by the device A to the target device indicates that the device A needs weather forecast, and then the target device sends data corresponding to a weather forecast part in the target weather data to the device A after acquiring the target weather data.
It should be noted that each of the multiple devices may communicate with each other by using a fixed communication protocol, specifically, a MESH network may be established, and the MESH network protocol is used for communication, or bluetooth may be used for communication.
In an exemplary embodiment, the step S206 may be implemented as follows:
step S51: determining, by the target device, second device information for each device in the set of devices, wherein the second device information includes at least one of: a media intervention control layer address MAC using an identification of an application of the target meteorological data;
step S52: and instructing the target equipment to encrypt the target meteorological data according to the second equipment information of each equipment in the group of equipment and the secret key of the local area network, and compressing and sending the encrypted data to each equipment in the group of equipment.
That is, the target device may encrypt and compress data to be sent to each device in a group of devices, and may further ensure the security of the data and the transmission efficiency of the data.
Through the steps, under the condition that the local area network is provided with the multiple devices, one target device is selected from the multiple devices, the target device is used for acquiring the target meteorological data from the cloud server, and the target meteorological data are sent to the other devices in the multiple devices. Because a device in the local area network uniformly acquires meteorological data from the cloud server, the occupied extranet broadband is less, and the occupied resources of the cloud server are less, so that the problem that a plurality of devices in the local area network respectively acquire meteorological data from the cloud server to occupy more extranet bandwidth and the resources of the cloud server is solved.
