The first device and the second device described in this specification have conventional structures and functions (such as product housing, power interface, basic home appliance function, etc.) of the electric products currently on the market, and this specification is not particularly described.
In the prior art, data generated by a main device and a sub device are mutually independent when the cloud is reported, and have no relevance, the used data model is shown in fig. 1, the sub device is directly connected with a data channel of a cloud server by means of the main device for transmission and reporting, when the cloud server analyzes and computes sub device data, and when the data meets specific conditions, a control flow is triggered, a gateway device (main device) is controlled to execute processing through a issuing instruction, and when the equipment which is related to the analyzed data and needs to execute the data is computed, a certain computing resource and time are required to be consumed, so that the main device can be found.

As shown in fig. 2, fig. 2 is a flowchart of a data transmission method according to at least one embodiment of the present disclosure, where the method is applied to a first device in a data transmission system, the system includes the first device, at least one second device, and a cloud server, the first device has a Wi-Fi module and a bluetooth module, and the second device includes the bluetooth module, and includes the following steps:
in step 102, after the first device obtains bluetooth data sent by the second device through bluetooth broadcast, a first data packet with a preset data format is generated, where the preset data format includes a first data format describing attribute data of the first device and a second data format describing extended attribute data, and the extended attribute data includes the bluetooth data.
In step 104, the first data packet is transmitted to a cloud server through Wi-Fi communication, so that the cloud server issues a control instruction by analyzing the first data packet.
After any second device generates data to be uploaded to the cloud server, the second device does not have Wi-Fi communication capability required by the cloud server, so that the second device transmits the data to the first device with Wi-Fi communication capability through the Bluetooth module of the second device, for example, a connection-free Bluetooth broadcasting mode is used.
The first device receives Bluetooth data sent by the second device through the Bluetooth module, takes the received Bluetooth data as extended attribute data of a second data format, and reports the extended attribute data and self attribute data generated by the first device to the cloud through the first data packet.
The preset data format includes a first data format describing attribute data of the preset data format and a second data format describing extended attribute data, and the embodiment is not limited to a specific format of the preset data format.
In one embodiment, the first data format is a Wi-Fi data format, and the generating the first data packet with the preset data format includes: and converting the Bluetooth data from a Bluetooth data format into the second data format, and adding the Bluetooth data into a Wi-Fi data format containing the attribute data of the first equipment to obtain a first data packet with a preset data format.
In this embodiment, extended attribute data is added on the basis of the original data model of the data packet in the Wi-Fi data format, as shown in fig. 3, in the data model in the preset data format designed in this scheme, in addition to the original attribute (own) including the attribute data of the first device, the newly added attribute (extension) is used as extended attribute data, and when the bluetooth data is converted into the second data format, method information in the bluetooth data of the second device is deleted, and attribute information is added to the attribute (extension).
After receiving the Bluetooth data in the Bluetooth data format, the first device analyzes and converts the Bluetooth data into a second data format describing the extended attribute data, and adds the second data format to the Wi-Fi data format containing the attribute data of the device, so that the Bluetooth data is uploaded to the cloud server as the extended attribute data, and the relevance between the Bluetooth data and the first device is increased.
The self attribute data in the preset data format comprises state parameters generated by the first equipment; the extended attribute data in the preset data format comprises at least one of the following: the device identification of the second device, the product type of the second device, the device model of the second device, the sensor attribute name of the second device, the sensor attribute type of the second device, the sensor attribute value of the second device.
For example, in the attribute (extension), the equipment category, the equipment identifier, the equipment unique code (which may be the MAC address of the bluetooth module of the equipment), the equipment sensor attribute name, the equipment attribute type, the equipment sensor attribute value and the timestamp are all information carried in the bluetooth data sent by the second equipment. For example, when the second device is a kitchen scale, after the kitchen scale is weighed, the generated bluetooth data content is 200g of tomato weight, wherein the attribute name of the device sensor is tomato, the attribute type of the device sensor is weight, and the attribute value of the device sensor is 200g. And after the first equipment steaming and baking box receives the Bluetooth data, the weighing data are written into an expansion attribute field of the data packet, and the cloud end is uploaded through the Wi-Fi module.
The data packet with the preset data format, which is designed by the scheme, can realize that the data of the cloud end reported by the second device belongs to the first device and is the expansion attribute data of the first device, when the first device uploads the Bluetooth data of the second device, the first device does not adopt a data transparent transmission mode to upload the data of the second device, but takes the data of the second device as a part of the data of the first device and is used as the data indirectly obtained by the first device, so that when the cloud end server receives the uploaded expansion first data packet, the cloud end server can analyze based on the expansion attribute data of the first data packet, when determining that the Bluetooth data triggers the control flow to be consumed by a device of a certain device type, the first device associated with the first data packet is not required to be searched in a large range, but is directly locked when the first device is of the device type, and a corresponding control instruction is issued to the first device.
In an exemplary home environment, the temperature sensor (second device) sends the detected temperature data in a bluetooth broadcast manner, after the air conditioner (first device) configured with the Wi-Fi module receives the temperature data, the temperature data is converted into extended attribute data in the first data packet and uploaded to the cloud, after the cloud analyzes the extended attribute data of the first data packet, the cloud triggers a control flow of the air conditioner type device, the cloud does not need to search and match all the air conditioner type devices, and directly sends a control instruction to the air conditioner associated with the first data packet, for example, the air conditioner refrigerating temperature is adjusted to 26 degrees.
The control instruction comprises control operation information of the first device and information in Bluetooth data, and the first device consumes the Bluetooth data by executing the control instruction.
Since one bluetooth device receives bluetooth broadcast data of other devices within the broadcast range when receiving the broadcast of another bluetooth device, the first device receives the influence of other unplanned devices when subscribing to receive the bluetooth broadcast of the second device.
In some embodiments, after the acquiring bluetooth data sent by the second device via bluetooth broadcast, the method further comprises:
checking whether the product type of the second device in the Bluetooth data is in a first white list or not, wherein the first white list is used for recording the product type supporting interconnection with the first device;
and discarding the Bluetooth data if the Bluetooth data is not in the first white list.
In this embodiment, the bluetooth data includes a product type of the second device, the first device further has a device verification function, and before a first data packet with a preset data format is generated, the bluetooth data is verified, so as to filter out an influence of an unscheduled product type device on data transmission, avoid an unrelated device from broadcasting data to block the data transmission and interfere with data processing of a cloud, and ensure efficiency of data processing. The first whitelist may be a list formulated by a device manufacturer, and the product types in the first whitelist may be types of devices communicating based on the same data transfer protocol.
For example, a first device of a category may receive a broadcast from a bluetooth device of another category, which is discarded by the first device because the product type of the other category is not in the first whitelist of the first device.
In some embodiments, after said checking whether the product type of the second device in the bluetooth data is in the first whitelist, the method further comprises:
if the device identifier is in the first white list, checking whether the device identifier of the second device is in a second white list of the first device, wherein the second white list is used for recording the device identifier which is interconnected with the first device;
discarding the Bluetooth data if the Bluetooth data is not in the second white list;
and if the first data packet is in the second white list, generating the first data packet with the preset data format.
In this embodiment, the bluetooth data further includes a device identifier of the second device, and the first device may further verify the bluetooth data, so that a user may manage the device for data transmission through the second whitelist. The user may manage the second whitelist of the first device, e.g., delete, add device identification, through an application associated with the first device. For example, a device in a home environment may receive a broadcast from a neighboring peer device, or a device in one room may be interfered by a broadcast from a peer device in another room, and the user may manually manage the second whitelist in the application of the user terminal, and remove unwanted devices. The device identifier may be a device model number, a device unique code, a device identification code, or the like.
When the product type of the second device is in the first white list and the device identification is in the second white list, the first device generates a first data packet in the preset data format.
In some embodiments, the generating the first data packet in the preset data format includes:
judging the broadcasting type of the Bluetooth data according to the identification of the Bluetooth data, and generating a first data packet with a preset data format in response to determining that the broadcasting type of the Bluetooth data is state type broadcasting.
When the second device transmits bluetooth data in a bluetooth broadcast manner, broadcast types of bluetooth data are generally classified into two types: one is request-like broadcasting, which will always be broadcast if no response is requested, such as: requesting Wi-Fi networking broadcasting, broadcasting once every 5S, and broadcasting all the time if networking is unsuccessful; one is a status-like broadcast, which is transmitted once at intervals, repeatedly transmitted a plurality of times, such as: the reminder broadcast is sent every 1S for 3 times continuously. The state type broadcast carries state information of the second device, so that the state information needs to be uploaded to the cloud as a record, and the request type broadcast generally does not need to be uploaded to the cloud, so that the first device can process Bluetooth data differently according to different broadcasting types of the Bluetooth data, and processing efficiency is improved.
For example, when the second device broadcasts bluetooth data, the broadcast format of the attribute part of the data packet is shown in fig. 4, the broadcast type is identified as 0 time representing state type broadcast, the broadcast type is identified as 1 time representing request type broadcast, and when it is determined that the broadcast type of the bluetooth data is state type broadcast, the first device generates a first data packet with a preset data format to mount the bluetooth data to the extended attribute data of its own data packet.
In addition, after the bluetooth data is received, whether the device identifier of the second device in the bluetooth data is in the first white list can be checked first, whether the device identifier of the second device is in the second white list of the first device is checked, then the broadcast type of the bluetooth data is judged, in order to avoid repeated broadcast reception, the bluetooth data can be thrown out if the checksum in the bluetooth data is consistent with the checksum of the last received bluetooth data, otherwise, the first data packet with the preset data format is received and generated. The checksum is calculated according to information except the time stamp in the Bluetooth data, and the checksum of the repeatedly transmitted Bluetooth data is the same.
In some embodiments, the method further comprises:
and transmitting request response information through Bluetooth in response to determining that the broadcasting type of the Bluetooth data is request type broadcasting.
For request broadcasting, the cloud end is not required to be uploaded for processing, processing load of the cloud end is reduced, and when the request broadcasting meets verification conditions of the first white list and the second white list, request response information is fed back through Bluetooth, for example, when the second equipment requests Wi-Fi networking broadcasting is received, networking allowing information is fed back, the second equipment is prevented from being in a broadcasting state all the time, and the first equipment is occupied for subscribing and receiving data channels of Bluetooth broadcasting of other second equipment.
