Description

Technical Field

[0001] This invention relates to the field of terminal operations, specifically to a data association analysis system and method for operational tasks of rugged mobile terminals. Background Technology

[0002] Rugged mobile devices are mobile devices developed for harsh working environments, including rugged phones, rugged tablets, and rugged laptops. They are dustproof, waterproof, and shockproof, enabling stable operation and communication in harsh areas such as rainforests, deserts, and plateaus. Due to the special working environment of rugged devices, communication processes face challenges such as limited spectrum bandwidth resources, high channel interference, and limited transmission time windows, making wireless signal transmission prone to interruptions.

[0003] In environments lacking sufficient infrastructure, ruggedized equipment relies on mobile signal transmitters for communication. However, as communication distance increases, the communication quality between some devices deteriorates rapidly, leading to communication problems such as phase imbalance, phase noise, and quantization interference. Especially in confined operating environments far from transmitter clusters, poor channel conditions result in a large amount of wireless signals and interference signals superimposed, compromising data transmission integrity and causing high latency and low transmission efficiency.

[0004] Furthermore, due to distance limitations, devices need to use relay systems for indirect communication. However, relay devices have low power efficiency, poor signal directivity, high error rate, and limited transmission sequence length, which reduces the throughput of the distributed network and affects the communication efficiency between rugged mobile terminals. Summary of the Invention

[0005] The purpose of this invention is to provide a system and method for analyzing task data in rugged mobile terminals, in order to solve the problems mentioned in the background art.

[0006] To solve the above-mentioned technical problems, the present invention provides the following technical solution: a task data association analysis system for rugged mobile terminals, comprising: a network construction module, a group communication module, a node collaboration module, an information sharing module, and a beam concentrating module; The network construction module is used to form a random multiple access network consisting of a transmitter, a receiver, and a relay. It simulates the user location distribution based on the communication density within each grid, groups users based on the maximum latency of the terminals, performs weighted clustering of different groups based on information age, and uses a cluster maximization algorithm to connect the nearest neighbor nodes of each terminal node to obtain communication groups. The group communication module is used to calculate the throughput of different groups based on information age and data packet reception rate, adjust the transmitter power and group resource block allocation to meet the throughput requirements, and the network enters a special communication state when the requirements cannot be met. The node collaboration module is used to control each group node to broadcast shared information and establish node links under special communication conditions. Among the successfully established node links, nodes with stable channels are selected as collaboration nodes. The transmitter transmission information is RS encoded, and the RS code check bit is broadcast as collaboration information within the group network. Nodes that fail to establish links will concatenate the received RS code check bit with packet loss information to obtain RS codewords, which are then sent to the collaboration nodes. The collaboration nodes recover the RS codewords and restore the original signal. The information sharing module is used to establish a resource block allocation matrix according to the throughput requirements of the nodes, allocate frequency resources to the cooperating nodes, enable isolated nodes to share information with the frequency bands of cooperating nodes, and the transmitter calculates the pilot matrix under equal power constraints with the goal of minimizing the sum of mean square errors, allocates time and frequency bands, and completes information transmission.

The device clustering unit is used to construct a wireless channel model between user terminals and relays. It performs clustering according to the maximum latency, grouping device terminals into communication clusters. Terminals in each cluster have consistent information age characteristics. Within a cluster, all nearest neighbor nodes that meet the exclusivity rate limit are accessed. The exclusivity rate is the probability that a node is allowed to exclusively access resources in a frequency band. The resulting set of nodes is used as a communication group.

[0008] Furthermore, the group communication module includes: a timed transmission unit and a dynamic access unit; The timing transmission unit is used to set a transmission time window according to the power-law distribution of the maximum delay, timestamp each data packet, discard data packets that are not received before the end of the time window, and calculate the ratio of the number of successfully received data packets to the total number of data packets within the transmission time window to obtain the data packet reception rate. The dynamic access unit is used to calculate the traffic throughput of each group. When a new device joins the communication, it adjusts the access probability of the new device in each group through the contention window protocol and the dynamic access protocol, updates the transmission time window and the scale of access users, and enters a special communication state when the communication network power or frequency band reaches the upper limit.

[0009] Furthermore, the node collaboration module includes: an information broadcasting unit, an encoding verification unit, and an information decoding unit; The information broadcasting unit is used to control the nodes to send node status information in fixed broadcast time slots or broadcast frequency bands.
