[ detailed description ] embodiments

In order to make the objects, technical solutions and advantageous effects of the present invention more clearly apparent, the present invention is further described in detail below with reference to the accompanying drawings and the detailed description. It should be understood that the detailed description and specific examples, while indicating the preferred embodiment of the invention, are intended for purposes of illustration only and are not intended to limit the scope of the invention.

It is also to be understood that the terminology used in the description of the invention herein is for the purpose of describing particular embodiments only and is not intended to be limiting of the invention. As used in the specification of the present invention and the appended claims, the singular forms "a," "an," and "the" are intended to include the plural forms as well, unless the context clearly indicates otherwise.

It should be further understood that the term "and/or" as used in this specification and the appended claims refers to and includes any and all possible combinations of one or more of the associated listed items.

In an embodiment of the present invention, a first aspect provides a bluetooth matrix networking method, which is used for establishing networking connections between a plurality of gateway devices and a plurality of bluetooth devices, constructing a matrix-collaborative-application-oriented wireless bluetooth star network, and providing free connections between a plurality of devices with bluetooth functions. The device comprises but is not limited to an intelligent household appliance, an intelligent audio and video device, a computer and other Internet of things devices with Bluetooth adapters. It should be noted that each bluetooth device and gateway device has its own unique MAC address for identification.

As shown in fig. 1, the bluetooth matrix networking method includes the following steps S101 to S103.

And S101, the equipment realizes the sensing function by scanning the broadcast packet of the node or the gateway and collects the state data information of the node.

Step S102, registering table rules, if the gateway device senses the broadcast data of the node device and obtains the MAC address of the node, matching locally at the gateway, if the gateway device registers, judging whether the relevant service needs parameter configuration, reading node data, upgrading the node and the like, otherwise, packaging and packaging according to the protocol and sending the service to a PC upper computer for coordination processing

Step S103, acquiring the mutual receiving signal strength information between any two Bluetooth devices, and calculating the distance between the two Bluetooth devices according to the signal strength.

In this step, each bluetooth device and gateway apparatus in the bluetooth matrix can sense the surrounding bluetooth devices, and automatically identify the state information of the relevant devices in the matrix, including Signal value (Received Signal Strength Indicator, RSSI), which is an indication of the Received Signal Strength, and is implemented after the back channel baseband receiving filter. The distance between the two bluetooth devices can then be calculated from the signal values. Further, Kalman filtering processing is firstly carried out on the received Bluetooth signals to obtain stable signal values.

Specifically, the calculation formula is as follows: d is 10 [ | RSSI | -a/(10 × n) ], where d is the calculated distance, RSSI is the received signal strength (usually a negative value, thus taking the absolute value), a is the signal strength when two bluetooth devices are 1 meter apart, and n is the environmental attenuation factor; the specific values of A and n are slightly different according to different equipment and terrains, and can be obtained through testing. Therefore, the distances between a plurality of bluetooth devices (including all gateway devices) are calculated, and a network connected with each other as nodes is obtained.

And step S104, planning a shortest path line capable of connecting all the Bluetooth devices according to the distance between every two Bluetooth devices.

In the step, a shortest path line connected with the Bluetooth equipment ad hoc network is planned according to the minimum distance between the Bluetooth equipment, the distance value is used as weight, nodes in the matrix network are combined into a directed graph, a Dijkstra algorithm is mainly adopted, a label method is adopted, and the directed graph has two labels, namely a T label and a P label. The T label is called a tentative label (tentative label), the P label is a permanent label (permanent label), and a P label is given to the node vi to indicate the length of the shortest path from the starting point vs to the node vi; giving node vi a T label indicating the upper bound of the estimated shortest path length from start vs to vi; in each step of the algorithm, the T label of a certain point is changed into a P label, and when the P label is obtained at the end point vt, the calculation is finished.

The algorithm step, marking vs with P, P (vs) 0, marking the rest nodes with T, T (vi) + ∞

If vi is the node which just obtains the P label, considering all nodes vj which can be reached by vi, and vj is the T label, modifying T (vj): t (vj) min [ T (vj), P (vi) + Lij ]

And comparing all nodes with T labels, wherein the minimum node is changed into a P label: p (vk) ═ min [ t (vi) ], step 2 is shown in fig. 8.

Using C language to realize algorithm, using an array dist for storing the current distance of each vertex, once the shortest path from the source point v to the vertex k is obtained, the disk [ k ] is the length of the shortest path from the source point to the vertex k. The vertex preceding j in the shortest path from the source point to vertex j is stored using the array pre, pre [ j ]. We can easily find the paths from the source point v to other vertices from the pre array.

The code is as follows:

and step S105, performing ad hoc network connection on all the Bluetooth devices according to the shortest path line through a plurality of gateway devices.

Specifically, the gateway device is used for sequentially connecting the node devices to be connected by calculating an optimal path according to the node information in the registry, each gateway node can be simultaneously connected with 8 nodes at most, the devices which are not connected need to be queued in a waiting queue, and the gateway devices take out the node information to be connected from the head to the head of the waiting queue after a channel is idle to initiate connection.

As shown in fig. 2, the network aware implementation steps:

and S101, the gateway equipment scans the broadcast packet of the equipment in the matrix, and defines the Bluetooth broadcast packet formats of the equipment node and the gateway in order to filter other Bluetooth equipment.

Broadcast format rules:

bluetooth low energy devices discover other devices through a broadcast channel, one device broadcasts and the other device scans.

As shown in fig. 9, the bluetooth broadcast packet is constructed as follows:

effective data part containing several broadcasting data units called AD Structure

Composition of AD Structure:

length indicating the Length of this AD Structure (excluding Length itself 1)

Type AD Type, mark what the piece of broadcast data represents, such as device name, uuid, etc.

Data AD data

Invalid data part, the length of the broadcast packet must be 31 bytes, if the valid data part is less than 31, the rest is complemented with 0, and the data of the part is invalid.

In order to realize the perception function of the Bluetooth matrix, a broadcast data format needs to be customized, and the system adds information such as node MAC, state and the like in a factory-defined field of a broadcast packet so as to facilitate a gateway to realize node matching and filtering, perceive the members of the matrix nodes and perform related service processing.

The used ID field is a Bluetooth name field (0x09), and a manufacturer information field (0xFF) realizes custom data

Different nodes and different divisions are provided for the MAC of the gateway equipment, and after the gateway equipment senses the broadcast information of the nodes or adjacent gateways in the matrix, the gateway equipment can distinguish different nodes and gateway types according to the MAC and execute related service processing.

And step S102, the acquired RSSI is taken as a weight and is attached to the node equipment list information.

And S103, the gateway equipment compares the acquired node MAC with the local MAC, if the local MAC is registered, the related service function is executed, otherwise, the MAC and RSSI are packaged and forwarded to a PC (personal computer) end for processing, the PC end counts the registry information of all the gateway equipment, and the PC end judges whether other equipment is registered or not.

And step S104, the PC terminal compares the received information in the total registry, if the received information is registered, the RSSI is compared, if the RSSI is lower, the original registration information is deleted, and the original registration information is synchronously sent to the corresponding gateway for updating the registry.

The system also supports the issue of a configuration table including information of all Bluetooth devices in the block to each gateway device, thereby completing the ad hoc network. Specifically, the configuration table of each gateway device can be configured by a user or automatically searched and identified by the gateway center according to the relevant algorithm and registered in the configuration table.

In summary, the bluetooth matrix networking method provided by the present invention plans the shortest path line for the bluetooth device ad hoc network connection according to the minimum distance between the bluetooth devices, and then performs the bluetooth device ad hoc network connection according to the shortest path line, thereby reducing the occupation of the connection channel, ensuring the stability of the bluetooth device control, and avoiding the problem of generating regional disconnection; meanwhile, networking is easy and convenient to operate, and flexibility, stability and durability of networking are improved.

As shown in fig. 3, the bluetooth matrix networking connection implementation step:

step S101, connecting node rule

(1) Unified bluetooth service and UUID

Bluetooth services, which include services, features, and attributes, are required in bluetooth devices. The service and the characteristics have a unique corresponding UUID, and each characteristic has attributes of read, write, notification and the like. A service may contain several properties (characteristics), each of which in turn contains several attributes (attributes) in which the data is stored. A service is established in the software for data transmission, which service contains three properties for transmitting status data packets, command data packets, message data packets, respectively. The three characteristics can be regarded as three different data channels, and different types of data packets are transmitted by channels, so that the data processing flow is simplified. The nodes and gateway data in the matrix network use unified user-defined service UUIDs for receiving and transmitting, and data interaction of the whole network is realized.

(2) Each Bluetooth device in the matrix has a unique MAC address, when a certain Bluetooth device has data to be sent, whether a data self-defined flag bit is located in a broadcast packet or not is determined, the gateway center scans surrounding broadcast packets in sequence and only processes the data flag bit in the broadcast packet of the bound MAC address, if the data flag bit is located, it is indicated that the slave Bluetooth product has data to be reported, at the moment, the gateway center can initiate connection through the MAC address of the node, and the data of the device is read after the connection. If the gateway center needs to actively connect with the designated slave node for control or configuration, the gateway center can initiate connection through the MAC address of the node and perform configuration and the like.

And step S102, the gateway receives the control instruction service output to the node equipment by the PC end, and actively connects the node equipment when the node needs to be operated.

And step S103, reading data reported by the Bluetooth equipment.

The gateway device needs to actively connect with a designated slave node for control or configuration, and may initiate connection through the MAC address of the node for configuration, and the like. Therefore, the communication method has the following advantages: the slave nodes are not limited by time slices and are more free; when the slave node and the central node are frequently handed over each other, theoretically, the length and time of data transmission are not required; the network stability is high, the requirement on the consistency of the crystal oscillators of all nodes in a time slice mode is high, and the communication of all nodes cannot be influenced by the tiny deviation of the crystal oscillators in an active monitoring polling mode; compared with a passive time slice mode, the program structure is simpler and clearer and is easy to understand.

In other embodiments, the gateway apparatus may be added to all bluetooth devices to calculate the shortest path line, and in this case, each gateway apparatus corresponds to a preset number of bluetooth devices closest to the gateway apparatus, where each bluetooth device is paired with only one gateway apparatus. Certainly, the method can also be based on an intelligent scheduling strategy algorithm, the Bluetooth devices in the matrix are efficiently matched and parameter configuration or upgrading is carried out, and data acquisition, data transmission and network data collection of the nodes are realized based on the intelligent master-slave nodes and the network collector of the Bluetooth communication, so that the wireless Bluetooth star network facing the matrix cooperative application is constructed.

The invention provides a Bluetooth matrix networking system, which is used for constructing a wireless Bluetooth star network facing to matrix cooperative application for a plurality of Bluetooth devices and providing free connection among a plurality of devices with Bluetooth functions, wherein the modules mainly covered by the system are a PC upper computer, a cloud server and a mobile APP.

After receiving the information from the serial port, the PC upper computer end processes the information by packaging (including the information unique number, the identification code of the sender equipment and the identification code of the receiver equipment) and then sends the information to other Bluetooth ad hoc network devices in the communication range of the PC upper computer end.

(3) After receiving the information after the packet processing, the Bluetooth matrix gateway device extracts the identification code in the data packet, and if the identification code of the receiver is the same as the identification code of the equipment connected with the Bluetooth ad hoc network device through the serial port, the Bluetooth matrix gateway device passes through and executes the related service function

(4) The gateway device transmits the data packet to the node device through the Bluetooth connection. If the identification codes are different, the node equipment does not process the data, and if the identification codes are different, the relevant data is processed.
