Detailed Description

The present invention will be described in further detail with reference to the accompanying drawings and examples. It is to be understood that the specific embodiments described herein are merely illustrative of the invention and are not limiting of the invention. It should be further noted that, for the convenience of description, only some of the structures related to the present invention are shown in the drawings, not all of the structures.

Before discussing exemplary embodiments in more detail, it should be noted that some exemplary embodiments are described as processes or methods depicted as flowcharts. Although a flowchart may describe the steps as a sequential process, many of the steps can be performed in parallel, concurrently or simultaneously. In addition, the order of the steps may be rearranged. The process may be terminated when its operations are completed, but may have additional steps not included in the figure. The processes may correspond to methods, functions, procedures, subroutines, and the like.

Furthermore, the terms "first," "second," and the like may be used herein to describe various orientations, actions, steps, elements, or the like, but the orientations, actions, steps, or elements are not limited by these terms. These terms are only used to distinguish one direction, action, step or element from another direction, action, step or element. For example, a first speed difference may be referred to as a second speed difference, and similarly, a second speed difference may be referred to as a first speed difference, without departing from the scope of the present application. The first speed difference and the second speed difference are both speed differences, but they are not the same speed difference. The terms "first", "second", etc. are not to be construed as indicating or implying a relative importance or implicitly indicating the number of technical features indicated. Thus, a feature defined as "first" or "second" may explicitly or implicitly include one or more of that feature. In the description of the present invention, "a plurality" means at least two, e.g., two, three, etc., unless specifically limited otherwise.

Fig. 1 is a system schematic diagram of an intelligent home control system according to an embodiment of the present invention, which is applicable to a situation of interaction between intelligent home devices. Referring to fig. 1, the smart home control system according to the embodiment of the present invention specifically includes: the system comprises a user terminal, a main control device and a plurality of household electrical appliances; the user terminal is connected with the main control equipment in an internet communication mode; the master control equipment is connected with each household appliance through a Bluetooth communication mode; the household appliances are connected point to point in a Bluetooth communication mode to form a Bluetooth home network.

Specifically, the intelligent home control system of the embodiment includes an external network and an internal network, wherein for the external network, since the distance limit is provided for bluetooth transmission, the external network initiates a command request to the master control device in an internet transmission mode; for the internal network, the internal network is composed of a main control device and a plurality of household appliances through a Bluetooth transceiver. As shown in fig. 2, all devices in the smart home together form a bluetooth home network, and similar to the P2P network, in the P2P bluetooth home network, there is no strict distinction between a client and a server, and each node functions as a client and a server. The nodes are equal, and any node can inform each node in the network of a message as long as the connection is made through Bluetooth.

The method includes the steps that data transmission is carried out between the main control device and each household appliance in a transmission mode similar to a P2P network, specifically, the user terminal sends a command request to the main control device, after the main control device receives the command request, the main control device forwards the corresponding command request to the corresponding household appliance in a Bluetooth broadcasting mode, and the household appliance receiving the command request executes the corresponding command. Furthermore, the household appliance executing the corresponding instruction feeds back a corresponding execution result to the main control device in a Bluetooth communication mode, and the main control device feeds back the corresponding execution result to the user terminal in an internet communication mode.

As an optional embodiment, before the master control device and each home appliance communicate, the identities of the master control device and each home appliance are mutually confirmed through bluetooth close contact. Specifically, before starting working, the identity between the equipment and the equipment needs to be confirmed through Bluetooth joint seal so as to facilitate normal transmission of subsequent data, and the equipment sends the identity data in a Bluetooth broadcast mode and receives the identity data of other equipment through Bluetooth so as to ensure that no external equipment illegally acquires the data.

As an optional embodiment, data interaction is performed between the home appliances in a bluetooth broadcast manner. Specifically, as shown in fig. 3, when operating, devices in the bluetooth network need to upload and download data, each device sends data in a bluetooth broadcast manner and then receives data in a broadcast manner, and finally each device receives a complete piece of data. Through the mode of bluetooth broadcast, also can carry out the transmission of data when the network condition is not good.

As an optional embodiment, each household appliance performs point-to-point connection through a bluetooth communication mode to form a plurality of bluetooth home networks. Specifically, as shown in fig. 4, a user sends a request to a bluetooth broadcasting device in a home through a mobile phone and the internet, because of the distance limitation of bluetooth transmission, multiple p2p network areas may need to be formed, different parts of data are sent to all devices through bluetooth broadcasting, data transmission is performed between the devices, the fault tolerance rate is high, and the transmission rate is high.

According to the technical scheme of the embodiment of the invention, the Bluetooth home network is formed by Bluetooth point-to-point connection, so that the dependence of the network when the network fails is reduced, and the intelligent home can still work normally under the condition that the home network condition is poor or the network is disconnected. Meanwhile, the Bluetooth is used for communication, the cost is lower, the power consumption is lower, the P2P is applied to the Bluetooth, the data receiving and sending efficiency is improved through decentralization, and the fault tolerance is higher.

It is to be noted that the foregoing is only illustrative of the preferred embodiments of the present invention and the technical principles employed. It will be understood by those skilled in the art that the present invention is not limited to the particular embodiments described herein, but is capable of various obvious changes, rearrangements and substitutions as will now become apparent to those skilled in the art without departing from the scope of the invention. Therefore, although the present invention has been described in greater detail by the above embodiments, the present invention is not limited to the above embodiments, and may include other equivalent embodiments without departing from the spirit of the present invention, and the scope of the present invention is determined by the scope of the appended claims.
