Description

Technical Field

[0001] The present invention relates to the technical field of communication management, and in particular to a device management method and system for terminal ad-hoc networks. Background Art

[0002] Tunnels are usually enclosed and narrow structures, and the natural environment has a great impact on the propagation of wireless signals. Their unique geographical features and materials lead to signal attenuation and multipath effects, restricting the signal coverage, communication quality, and stability of traditional communication technologies in tunnels.

[0003] In the prior art, this problem is usually solved by laying dedicated communication lines or relay devices, but these methods are costly and complex to maintain. On the one hand, fixed relay devices are usually used in the prior art for static configuration, lacking intelligent correlation analysis. This method cannot adapt to the rapidly changing tunnel environment, easily causing non-automated optimization of data transmission paths, increasing latency and error rates. On the other hand, fixed broadcast parameters are usually used in the prior art and cannot be dynamically adjusted according to changes in network status. This may lead to low data transmission efficiency and even data loss in complex environments. Therefore, at the present stage, an efficient and intelligent communication management technical solution is needed to solve the above problems. Summary of the Invention

[0004] The purpose of the present invention is to provide a device management method and system for terminal ad-hoc networks to solve the problems raised in the above background art.

[0005] To solve the above technical problems, the present invention provides a device management method for terminal ad-hoc networks, including:

[0006] S100. Collect historical logs and parameter information of all mobile terminals.

[0007] S200. Define transmission objects and proxy objects according to the parameter information and associate them, and calculate the first coefficient of the associated objects.

[0009] S400. Update the objects and set broadcast parameters, calculate the third coefficient of the proxy objects to achieve packet relaying, and record data upload information into the historical logs.

[0010] In S100, the mobile terminal refers to an electronic device with wireless communication functions. The historical logs include transmission records of all data packets, and each transmission record includes the transmission path and the correct rate.

[0011] The transmission path refers to the transmission channel constructed between the mobile terminal and the data center. The transmission path is composed of several connected nodes, and the nodes are mobile terminals or data centers.

[0012] The data center deployment methods are any one or a combination of multiple methods among local data centers, cloud data centers, and edge data centers.

[0013] The correct rate refers to the ratio of the amount of valid data successfully transmitted between two adjacent nodes in the transmission path to the total amount of transmitted data during data transmission.

[0014] The parameter information includes signal strength, identifier, location, and broadcast information. The signal strength refers to the strength of the electrical signal between the mobile terminal and the data center. The identifier is used to distinguish different mobile terminals, and the location refers to the location of the mobile terminal.

[0015] The broadcast information includes a performance table and broadcast parameters. The performance table includes the adjustable broadcast frequency and broadcast duration of the mobile terminal. The broadcast parameters refer to the currently set broadcast frequency and broadcast duration of the mobile terminal. The mobile terminal regularly turns on the Bluetooth function to broadcast its parameter information according to the broadcast frequency and automatically turns off the Bluetooth function after the on duration reaches the broadcast duration, and repeats this process.

[0016] S200 includes:

[0017] S201. Set the signal strength threshold Q, regard the mobile terminals with signal strength less than Q as transmission objects, and other mobile terminals as proxy objects. Each transmission object is associated pairwise with other proxy objects in turn. Ensure that each pair of associated objects contains only one transmission object and one proxy object.

[0018] S202. Obtain the identifier BSF of the transmission object and the identifier BSF of the proxy object under the associated object DX c and analyze the transmission paths of each transmission record in the historical log, filter out the transmission paths that simultaneously contain adjacent BSF d and BSF c and whose transmission direction is from BSF d to BSF c to BSF d and mark them.

[0019] S203. Count the number w of all marked transmission paths, analyze the correct rate from BSF c to BSF d in each marked transmission path and the correct rate from BSF d to the next node Obtain the latest parameter information of the transmission object and the proxy object under the associated object DX, and substitute it into the formula to calculate the first coefficient FXS of the associated object DX DX :

[0020]

[0021] Where α and β are constants greater than 1, Q d and Q c are the signal strengths of the proxy object and the transmission object respectively, (x1, y1) and (x2, y2) are the positions of the proxy object and the transmission object respectively, and the first coefficient of each pair of associated objects is calculated respectively.

[0022] When the signal strength of the proxy object is greater than that of the transmission object, the correct rate in the data transmission process is higher, and the shorter the distance between the two, the greater the first coefficient.

[0023] S300 includes:

[0024] S301. Set a coefficient threshold C, and cancel the association relationship between the proxy object and the transmission object of the associated object whose first coefficient is less than C. Establish a relationship set for each proxy object, and put the identifiers of the transmission objects having an association relationship with the proxy object into the corresponding relationship set.

[0025] S302. Count the number S of all transmission objects in the DL relationship set of the proxy object, analyze the first coefficient between the proxy object DL and each transmission object, and sum these first coefficients to obtain Obtain different broadcast frequencies and broadcast durations in the performance table of the proxy object DL, and generate N broadcast environments according to different combinations of values.

[0026] Each broadcast environment represents a broadcast frequency and a broadcast duration with definite values. Among different broadcast environments, one of the parameters may be the same, but the situation where both parameters are the same will not occur. Each broadcast environment is the broadcast frequency and broadcast duration that can be set by the mobile terminal.

[0027] S303. Set a sampling duration H, obtain the latest broadcast parameters of the proxy object DL corresponding to each transmission object, and analyze the sum of the overlapping durations of the broadcast duration between the proxy object DL running in the i-th broadcast environment and the k-th transmission object within the sampling duration H Substitute into the formula to calculate the second coefficient of the proxy object DL in the i-th broadcast environment

[0028]

[0029] In the formula, FXS k is the first coefficient between the proxy object DL and the k-th transmission object.

[0030] S304. Calculate the second coefficient of the proxy object DL in each broadcast environment respectively, and select the broadcast environment with the highest second coefficient as the broadcast parameter of the proxy object DL. By analogy, set the broadcast parameters for each proxy object.

[0031] S400 includes:

[0032] S401. Each transmission object regularly turns on the Bluetooth function and broadcasts its own parameter information according to the original broadcast parameter, and each proxy object regularly turns on the Bluetooth function and broadcasts its own parameter information according to the set broadcast parameter. Update the transmission object and the proxy object in real time according to the change of the signal strength of the mobile terminal, and set the broadcast parameter.

[0033] The mobile terminal regularly broadcasts its own broadcast parameter according to the broadcast frequency to determine whether it is a transmission object or a proxy object. The broadcast parameter of the transmission object does not need to be changed, while the broadcast parameter of the proxy object changes.

[0034] S402. When a proxy object needs to upload a data packet to the data center, it directly uploads it through its own network communication module. When a transmission object needs to upload a data packet to the data center, calculate the waiting duration required between the current time and the start time of the overlapping broadcast duration of each corresponding proxy object according to the broadcast parameter.

[0035] In a closed long-distance tunnel environment, the terminal device with BLE Mesh communication ability realizes self-organizing network connection through the built-in BLEMesh module. In the node discovery stage, the device regularly broadcasts its own information and listens to other devices. In the network formation stage, it automatically joins the BLE Mesh network according to the received broadcast information to form a multi-hop mesh network. The transmission path and direction are adjusted in real time through a distributed algorithm to ensure the stability of the link. Finally, the data is transmitted through the BLE Mesh network, and each device is both a data sender and a relay node, thus improving the reliability of communication.

[0036] S403. Divide the first coefficient of each proxy object by the waiting duration to obtain the third coefficient, and mark the proxy object with the highest third coefficient. During the overlapping broadcast duration, the transmission object sends the data packet to the marked proxy object, and the marked proxy object forwards it to the data center. Record the transmission path and the correct rate during the data upload process, generate a transmission record and store it in the historical log.

The correct rate refers to the ratio of the amount of valid data successfully transmitted between two adjacent nodes in the transmission path to the total amount of transmitted data during data transmission.

[0041] The device parameter acquisition unit is used to collect the signal strength, identifier, location, and broadcast information of the mobile terminal. The signal strength refers to the strength of the electrical signal between the mobile terminal and the data center. The identifier is used to distinguish different mobile terminals. The location refers to the location of the mobile terminal. The broadcast information includes a performance table and broadcast parameters. The performance table includes the adjustable broadcast frequency and broadcast duration of the mobile terminal. The broadcast parameters refer to the currently set broadcast frequency and broadcast duration of the mobile terminal.

[0043] The device analysis unit is used to set the transmission objects and proxy objects. Set a signal strength threshold Q, and use the mobile terminals with signal strength less than Q as transmission objects, and other mobile terminals as proxy objects.

[0044] The association definition unit is used to associate the objects and calculate the first coefficient.

[0045] First, each transmission object is successively associated with other proxy objects pairwise to obtain the identifier BSF of the transmission object under the associated object DX c and the proxy object identifier BSF d , analyze the transmission path of each transmission record in the historical log, and filter out the transmission paths that simultaneously contain adjacent BSF c and BSF d and the transmission direction is from BSF c to BSF d and mark them.

[0046] Secondly, count the number w of all marked transmission paths, and analyze the BSF in each marked transmission path c to BSF d correct rate and the correct rate of BSF d to the next node Obtain the latest parameter information of the transmission object and the proxy object under the associated object DX.

[0053] Finally, obtain different broadcast frequencies and broadcast durations in the performance table of the proxy object DL, and generate N kinds of broadcast environments according to different combinations of values.

And so on, set the broadcast parameters for each proxy object.

[0058] The intelligent transmission module is used to update the transmission object and the proxy object, and set the broadcast parameters.

[0059] When the transmission object needs to upload data packets to the data center, calculate the waiting duration required between the current time and the start time of the overlapping broadcast duration for each corresponding proxy object according to the broadcast parameters. Divide the first coefficient of each proxy object by the waiting duration to obtain the third coefficient, and mark the proxy object with the highest third coefficient.
