In this embodiment, a method for detecting signal quality of the first node is provided, where the method is applied to the first node in a mesh network, and the mesh network further includes: fig. 2 is a flowchart of a method for detecting signal quality according to an embodiment of the present invention, and as shown in fig. 2, the flowchart includes the following steps:
step S202, the first node sends a node discovery message to a destination address, where the destination address is a multicast address of a preset multicast group, and the preset multicast group includes: a plurality of second nodes;
step S204, the first node receives a node response message from the destination address;
in step S206, the first node determines the signal quality of the mesh network based on the node response message.
Through the steps, a mode that a first node in a mesh network sends a node discovery message to a destination address, the destination address is a multicast address of a preset multicast group, and the preset multicast group comprises a plurality of second nodes can be adopted, the first node receives a node response message from the destination address and determines the signal quality of the mesh network based on the node response message, and the purpose of detecting the signal quality of the node in the mesh network by using the node discovery message sent to the multicast address and the node response message received by the first node is achieved, so that the technical effects of reducing the operation complexity of a signal quality detection process and improving the detection efficiency are achieved, and the technical problems that the signal quality detection mode of the node in the mesh network provided in the related technology is complex in operation and long in time consumption are solved.
Optionally, the first node is a first smart device, the plurality of second nodes are a plurality of second smart devices, the first smart device is configured with a home gateway module, the home gateway module is configured to connect the plurality of second smart devices to a wide area network, the first smart device and the plurality of second smart devices are configured to provide different types of initial services, and the initial services are independent of network connection services. In an optional embodiment, the first smart device and the second smart device are both smart home devices (e.g., smart air conditioners, smart sockets, and smart lamps). Through gateway generalization processing, can be with the module embedding that possesses the gateway function to any intelligent device that can supply power often to make these intelligent device newly-increased gateway function on original function's basis. For example: the initial service that intelligent air conditioner provided is for refrigerating or heating the service, through with the embedding of home gateway module to intelligent air conditioner in, this intelligent air conditioner will be on the basis of original function newly-increased gateway function. For another example: the initial service that intelligent lamps and lanterns provided is lighting service, through with the embedding of home gateway module to intelligent lamps and lanterns, this intelligent lamps and lanterns will be on the basis of original function newly-increased gateway function. Therefore, the detection mode of the signal quality is suitable for intelligent equipment subjected to gateway generalization processing.
The home gateway module can be inserted into the intelligent equipment through the peripheral interface of the intelligent equipment, and can be embedded into the intelligent equipment in advance in the production process of the intelligent equipment.
Optionally, in step S206, the first node determining the signal quality based on the node response message may include performing the steps of:
in step S2061, the first node determines the signal quality of the mesh network based on the number of the node response messages and sends out indication information, wherein the indication information is used for indicating the signal quality.
When the device Node is deployed in the mesh network, if the signal quality of the first Node in the mesh network is expected to be intuitively known, the first Node can be controlled to periodically or regularly trigger and send a Node Discovery (Node Discovery) message to a multicast address (for example: 0xCCC) of a preset multicast group. Then, the first Node receives Node Response messages returned by the second nodes from the multicast address. Therefore, the first node can determine the detection result based on the number of the node response messages and further send out the indication information. The indication information is used to indicate signal quality. If the larger the number of received node response messages, it indicates that the more second nodes are deployed around the first node, the better the signal quality. After the first node obtains the detection result, the first node may prompt the user of the signal quality of the node in the mesh network through a light emitting device or a speaker configured on the first node.
It should be noted that the multicast address of the preset multicast group may be dynamically allocated. The other nodes except the first node in the mesh network can dynamically join or leave the preset multicast group.
Optionally, in step S2061, the sending, by the first node, the indication information based on the number of the node response messages may include performing the following steps:
step S20611, the first node determines the flicker frequency of the indicator light on the first node based on the number of the node response messages;
in step S20612, the first node controls the indicator light to send out the indication information according to the flashing frequency.
Taking the example of a light emitting device (e.g., an indicator light) on a first node (e.g., a smart ceiling light), the first node may determine a frequency of flashing of the indicator light on the first node based on the number of node response messages. That is, if the first node receives a larger number of node response messages, the frequency of blinking of the indicator light on the first node is higher. Conversely, if the number of node response messages received by the first node is lower, the frequency of flashing of the indicator light on the first node is lower. Therefore, the user can know the signal quality of the nodes in the mesh network according to the flashing speed of the indicator lamp.
Optionally, in step S2061, the sending, by the first node, the indication information based on the number of the node response messages may include performing the following steps:
step S20613, the first node determines the color variation amplitude of the indicator light on the first node based on the number of the node response messages;
in step S20614, the first node controls the indicator light to send out the indication information according to the color variation amplitude.
Still taking the example of a light emitting device (e.g., an indicator light) on a first node (e.g., a smart ceiling light), the first node may determine the magnitude of the color change of the indicator light on the first node based on the number of node response messages. That is, the color change of the indicator light is divided into a plurality of levels. For example: the color change of the indicator light is divided into five levels from low to high, namely deep red, dark red, yellow, blue and green, which respectively indicate that the signal quality of the nodes in the mesh network is extremely poor, general, high and very good. The greater the number of node response messages received by the first node, the more highly graded the magnitude of the color change of the indicator light on the first node (e.g., from yellow to green). Conversely, if the first node receives a smaller number of node response messages, the magnitude of the color change of the indicator light on the first node is more toward a lower level (e.g., from yellow to deep red). Therefore, the user can know the signal quality of the nodes in the mesh network according to the color change amplitude of the indicator lamp.
Furthermore, in an alternative embodiment, taking the speaker (e.g., speaker) of the first node (e.g., smart speaker) as an example, the first node may determine the playing content of the speaker of the first node based on the number of node response messages. For example: during the music playing process of the smart sound box, if the number of the node response messages can be determined, a voice prompt can be inserted. For example: the signal quality of the intelligent sound box in the mesh network is good. Therefore, the user can know the signal quality of the nodes in the mesh network according to the voice prompt content.
In an alternative embodiment, taking the speaker (e.g., electronic alarm clock horn) and the display device (e.g., electronic alarm clock display screen) on the first node (e.g., intelligent electronic alarm clock) as an example, the first node may determine the display content of the network signal identifier of the electronic alarm clock display screen and the playing content of the electronic alarm clock horn based on the number of the node response messages. For example: in the fixed-point time reporting process of the intelligent electronic alarm clock, if the number of the node response messages can be determined, a voice prompt can be inserted. For example: the intelligent electronic alarm clock has good signal quality in the mesh network. Meanwhile, the display content of the network signal identifier of the electronic alarm clock display screen can be determined. For example: and adopting a signal lattice number representation mode similar to that of the mobile terminal, if the number of the node response messages received by the intelligent electronic alarm clock is more, the number of the signal lattices identified by the network signals is more. On the contrary, if the number of the node response messages received by the intelligent electronic alarm clock is smaller, the number of the signal grids identified by the network signals is smaller. Therefore, the user can know the signal quality of the nodes in the mesh network according to the voice prompt content.
Through the above description of the embodiments, those skilled in the art can clearly understand that the method according to the above embodiments can be implemented by software plus a necessary general hardware platform, and certainly can also be implemented by hardware, but the former is a better implementation mode in many cases. Based on such understanding, the technical solutions of the present invention may be embodied in the form of a software product, which is stored in a storage medium (e.g., ROM/RAM, magnetic disk, optical disk) and includes instructions for enabling a terminal device (e.g., a mobile phone, a computer, a server, or a network device) to execute the method according to the embodiments of the present invention.
