Description

Technical Field

[0001] This invention relates to the field of data transmission and protection technology, and more specifically, to a data transmission and protection method and system for wireless sensors. Background Technology

[0002] With the deepening integration of technology and sports, the demand for wireless sensor technology in youth sports training scenarios is becoming increasingly prominent. The training system relies on a series of smart hardware devices such as chip basketballs, Q1 wristbands, smart backboards, and chip jump ropes to build a digital training scenario covering the entire process before, during, and after class.

[0003] The distribution of sensor nodes changes dynamically with the training venue (such as different training areas in a basketball court) and the movement of trainees. The transmission environment is affected by factors such as the density of people and signal interference from equipment (such as the superposition of signals generated by multiple sensors working simultaneously), making it more complex than traditional fixed scenarios. This places higher demands on the real-time performance, accuracy, and stability of wireless sensor data transmission. In complex dynamic environments, the impact of sensor parameters and location on transmission performance is often overlooked, and the collaborative transmission capability between sensors is not effectively analyzed, resulting in poor collaborative transmission stability and frequent problems such as data loss and delay, which seriously affect the reliability of data transmission. Therefore, a data transmission and protection method and system for wireless sensors is proposed. Summary of the Invention

[0004] The purpose of this invention is to provide a method and system for data transmission and protection of wireless sensors, so as to solve the problems mentioned in the background art.

[0005] To address the aforementioned technical problems, one objective of this invention is to provide a data transmission and protection method for wireless sensors, comprising the following steps: S1. Obtain the data transmission record of the wireless sensor, and at the same time obtain the parameter specifications and location data of the wireless sensor; S2. Combine parameter specifications with location data to analyze the mutual transmission performance of wireless sensors, and filter wireless sensors for collaborative transmission based on mutual transmission performance to establish a collaborative list of wireless sensors. S3. Obtain the remaining transmission status of the wireless sensors, and prioritize the wireless sensors in the collaboration list based on the remaining transmission status and location data. S4. Set a protection transmission threshold. Enable collaborative transmission for the wireless transmitter by setting the protection transmission threshold and the remaining transmission status. Allocate collaborative transmission data to the wireless sensor based on the data transmission record and the collaborative list. S5. The transmitted data is temporarily stored in the wireless sensor, and the transmitted data is verified by the data receiver. Based on the verification result, the data is deleted from the wireless sensor data.

[0006] As a further improvement to this technical solution, step S1 establishes a data storage module at the data receiving end, and then uses the data storage module to save the data transmission records of the wireless sensor, while simultaneously acquiring the parameter specifications and location data of the wireless sensor at the data receiving end.

[0007] As a further improvement to this technical solution, step S2 is as follows: S2.1. For the transmission between wireless sensors, analyze the mutual transmission performance based on parameter data and location data to obtain the mutual transmission performance between wireless sensors. S2.2 Simulate collaborative transmission between wireless sensors based on their mutual transmission performance, obtain the simulated transmission results between wireless sensors, and filter out wireless sensors with unstable collaborative transmission based on the simulated transmission results, retaining only the wireless sensors with stable collaborative transmission. S2.3. Create a collaboration list for each wireless sensor and add the wireless sensors retained in S2.2 to the collaboration list.

[0008] As a further improvement to this technical solution, S3 monitors the real-time transmission status of the wireless sensor through the data receiving end, extracts the comprehensive transmission status according to the parameter specifications, and extracts the remaining transmission status by combining the comprehensive transmission status with the real-time transmission status, thereby obtaining the remaining transmission status of the wireless sensor during the transmission process.

[0009] As a further improvement to this technical solution, step S3 is as follows: S3.1. Take the wireless sensor in the collaboration list as the central wireless sensor, and analyze the distance values ​​between the wireless sensors in the collaboration list and the central sensor to obtain the distance values ​​corresponding to the wireless sensors in the collaboration list. S3.2. Combine the remaining transmission status of the wireless sensor with the distance value to perform priority value analysis, obtain the priority value corresponding to the wireless sensor, and sort the wireless sensor in the collaboration list according to the priority value.

[0010] As a further improvement to this technical solution, step S4 is as follows: S4.1 Set a protection transmission threshold based on the overall transmission status and data transmission records; S4.2. Combine the remaining transmission status of the wireless sensor with the protection transmission threshold for collaborative transmission analysis. If the remaining transmission status meets the protection transmission threshold requirements, then collaborative transmission is enabled for the wireless sensor. Otherwise, if the remaining transmission status does not meet the protection transmission threshold requirements, then monitoring continues. S4.3 For wireless sensors that have enabled cooperative transmission, perform cooperative transmission data analysis based on the real-time transmission status and data transmission records to obtain the cooperative transmission data that the wireless sensor needs to send. S4.4. Combine the collaborative transmission data with the remaining transmission status of the wireless sensors in the collaborative list to allocate the collaborative transmission data, and determine the collaborative transmission data that the wireless sensors in the collaborative list need to receive.

[0011] As a further improvement to this technical solution, when S4.4 performs cooperative data transmission allocation, the transmission state occupied will not cause the remaining transmission state to fall below the protection transmission threshold. Meanwhile, the wireless sensors that need to transmit data collaboratively send a portion of the data to be transmitted as collaborative transmission data to the wireless sensors in the collaborative list, and then the wireless sensors in the collaborative list send it to the data receiving end.

[0012] As a further improvement to this technical solution, when the S5 data terminal performs verification, it copies and sends the received data to the wireless sensor at the data source, and then compares the data. If the data matches, the data is deleted in the wireless sensor; otherwise, if the data does not match, the wireless sensor resends the data until the data matches. After receiving collaborative transmission data, the wireless sensors in the collaboration list do not save it, but send it directly to the data receiving end.

[0013] The second objective of this invention is to provide a data transmission and protection system for wireless sensors, including any one of the above-described data transmission and protection methods for wireless sensors, comprising a collaborative screening unit, a data allocation unit, and a data verification unit. The collaborative screening unit is used to acquire the data transmission records of the wireless sensors, and at the same time acquire the parameter specifications and location data of the wireless sensors. It combines the parameter specifications with the location data to analyze the mutual transmission performance of the wireless sensors, and performs collaborative transmission screening of the wireless sensors based on the mutual transmission performance to establish a collaborative list of wireless sensors. The data allocation unit is used to obtain the remaining transmission status of the wireless sensor, prioritize the wireless sensors in the collaboration list according to the remaining transmission status and location data, set a protection transmission threshold, enable collaborative transmission of the wireless transmitter through the protection transmission threshold and the remaining transmission status, and allocate collaborative transmission data to the wireless sensor according to the data transmission record and the collaboration list. The data verification unit is used to temporarily store the transmitted data in the wireless sensor, and to verify the transmitted data through the data receiving end. Based on the verification result, the data is deleted from the wireless sensor data.

[0014] Compared with the prior art, the beneficial effects of the present invention are as follows: 1. A method and system for data transmission and protection of wireless sensors, which acquires sensor parameter specifications and location data, analyzes mutual transmission performance, and establishes a collaborative list of stable and cooperative sensors to ensure the basic stability of collaborative transmission from the source. Simulating the transmission process and screening out unstable sensors according to strict standards further ensures the reliability of collaborative transmission. At the same time, the two-way verification mechanism at the data receiving end can detect and correct transmission errors in a timely manner, ensuring the accuracy of data transmission.

[0015] 2. A data transmission and protection method and system for wireless sensors, which prioritizes the sensors in the cooperative list based on the remaining transmission status and distance, can select more suitable partners during cooperative transmission to avoid resource waste, and ensures that the remaining transmission status of each sensor is not lower than the protection threshold during data allocation, which can prevent individual sensor overload, balance the load, and improve the overall transmission efficiency. In addition, the cooperative sensors forward the received data directly without saving it, reducing storage resource occupation and data retention delay, and further improving efficiency.

[0016] 3. A data transmission and protection method and system for wireless sensors, which monitors the sensor transmission status in real time, dynamically adjusts the order of the collaboration list, enables the system to adapt to changes in sensor status, maintains efficient collaboration, protects the setting of transmission thresholds, and combines the sensor's comprehensive transmission status and historical records to ensure that the sensor can still operate stably after collaborative transmission is enabled, avoids failures or performance degradation caused by collaborative transmission, and ensures the safe and stable operation of the system. At the same time, the mechanism of temporarily saving data and deleting it after verification ensures data traceability, releases storage space, and enhances the adaptability of system resource management.

Detailed Implementation

[0018] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0019] like Figure 1 - Figure 4 As shown, one of the objectives of this invention is to provide a data transmission and protection method for wireless sensors, comprising the following steps: S1. Obtain the data transmission record of the wireless sensor, and at the same time obtain the parameter specifications and location data of the wireless sensor; This provides foundational data support for subsequent analysis and processing, including three key types of information: historical transmission records of the wireless sensor, the device's own parameter specifications (such as transmission power, bandwidth, etc.), and the sensor's physical location data.

[0020] S1 establishes a data storage module at the data receiving end, and then uses the data storage module to save the data transmission records of the wireless sensor. At the same time, the parameter specifications and location data of the wireless sensor are acquired at the data receiving end.

[0021] First, a dedicated data storage module is built at the data receiving end. This module has the functions of data classification and storage, access control, and long-term storage, providing basic support for subsequent data management and retrieval. Then, through the communication connection established between the data receiving end and the wireless sensor, the data transmission records generated by the sensor in real time (including transmission time, data volume, transmission status, etc.) are continuously sent to the data storage module. The module organizes and saves them according to preset formats and rules. After that, the data receiving end sends parameter acquisition requests to each wireless sensor. After the sensor responds to the request, it transmits its own parameter specification information (such as transmission power, communication frequency band, data transmission rate limit, energy consumption standard, etc.) to the receiving end. The receiving end organizes this information and stores it in the data storage module. The data receiver obtains the real-time location data of each wireless sensor through interaction with the sensor. After verifying and standardizing the location data, the receiver associates it with the corresponding sensor identifier and stores it together in the data storage module.

[0022] S2. Combine parameter specifications with location data to analyze the mutual transmission performance of wireless sensors, and filter wireless sensors for collaborative transmission based on mutual transmission performance to establish a collaborative list of wireless sensors. Devices with stable collaborative transmission capabilities are selected from numerous sensors to build a collaborative list, laying the foundation for efficient collaboration in the future. The steps for S2 are as follows: S2.1. For the transmission between wireless sensors, analyze the mutual transmission performance based on parameter data and location data to obtain the mutual transmission performance between wireless sensors. Based on the parameter and location data of the sensors, the transmission performance between any two sensors is analyzed. The signal attenuation is evaluated by combining the relationship between transmission power and distance. The transmission stability is judged based on the anti-interference capability and the surrounding environment. These factors are combined to determine the mutual transmission performance between the sensors. S2.2 Simulate collaborative transmission between wireless sensors based on their mutual transmission performance, obtain the simulated transmission results between wireless sensors, and filter out wireless sensors with unstable collaborative transmission based on the simulated transmission results, retaining only the wireless sensors with stable collaborative transmission. For each pair of sensors with transmission capabilities, a collaborative transmission process is simulated. In a simulated environment, the data transmission situation under actual working conditions is simulated, and key indicators such as transmission delay, data loss rate, and signal fluctuation amplitude are recorded to form simulated transmission results. At the same time, collaborative transmission stability evaluation criteria (such as upper limit of data loss rate, allowable range of signal fluctuation, etc.) are set, and the simulated transmission results are compared with the criteria.

[0023] For sensors that do not meet the stability requirements, they are excluded from the list of potential collaborating partners, and only sensors with stable transmission are retained, as shown in the following formula: ; Among them, S stad For the cooperative transmission stability score, L is the data loss rate during the simulated transmission process, V is the fluctuation coefficient of the transmitted signal strength, D is the average transmission delay, and α, β, and γ are weighting coefficients. S2.3. Create a collaboration list for each wireless sensor and add the wireless sensors retained in S2.2 to the collaboration list.

[0024] S3. Obtain the remaining transmission status of the wireless sensors, and prioritize the wireless sensors in the collaboration list based on the remaining transmission status and location data. The order of the collaboration list is dynamically adjusted based on real-time status to ensure that the best partner can be selected first when collaboration is needed. S3 monitors the real-time transmission status of the wireless sensor through the data receiver, extracts the comprehensive transmission status according to the parameter specifications, and extracts the remaining transmission status by combining the comprehensive transmission status with the real-time transmission status, thereby obtaining the remaining transmission status of the wireless sensor during the transmission process.

[0025] The data receiving end continuously monitors the current transmission status of the wireless sensor through a real-time communication link established with the wireless sensor, including dynamic changes in real-time data transmission rate, current channel occupancy, instantaneous signal strength, and current energy consumption level. This real-time data is recorded in the data storage module in real time. Then, based on the parameter specifications of the wireless sensor and its historical transmission performance, a comprehensive status index reflecting the long-term transmission capability of the sensor is extracted, such as average transmission efficiency, long-term stability coefficient, and historical maximum load capacity, forming a comprehensive transmission status profile. Then, the overall transmission status is correlated with the real-time transmission status. By comprehensively evaluating the matching degree between the sensor's current load and its inherent capabilities, the remaining transmission workload, remaining transmission time, and remaining channel resources of the sensor in the current state are calculated. The remaining transmission status of the wireless sensor is determined by combining these indicators, as shown in the following formula: ; Among them, R i C represents the remaining transmission capacity of the i-th wireless sensor. i U represents the maximum transmission capacity of the i-th wireless sensor. i Let be the current transmission load rate of the i-th wireless sensor; ; Among them, T rem，i E represents the remaining transmission battery life of the i-th wireless sensor. rem，i Let P be the remaining battery power of the i-th wireless sensor. cur，i The current transmission power of the i-th wireless sensor; ; Among them, S rem，i For the overall remaining transmission state score of the i-th wireless sensor, T std，i Let w1 be the standard battery life of the i-th wireless sensor, and w2 be weighting coefficients.

[0026] The steps for S3 are as follows: S3.1. Take the wireless sensor in the collaboration list as the central wireless sensor, and analyze the distance values ​​between the wireless sensors in the collaboration list and the central sensor to obtain the distance values ​​corresponding to the wireless sensors in the collaboration list. Identify the central wireless sensor for each collaboration list and use it as the reference point for distance calculation. Define all wireless sensors included in the current collaboration list as the scope for distance analysis and sorting. Then, based on the location data of the central sensor and each sensor in the collaboration list, calculate the straight-line distance between each sensor and the central sensor. Associate the calculated distance values ​​with the corresponding sensor identifiers to form a distance information table for later use. The formula is as follows: ; Among them, F d，j D represents the distance fit coefficient of sensor j in the collaborative list. ij Let D0 be the distance between the center sensor i and sensor j, D0 be the distance attenuation reference value (a constant set according to the sensor transmission performance), and e be the natural constant. S3.2. Combine the remaining transmission status of the wireless sensors with the distance values ​​to perform priority value analysis, obtain the priority values ​​corresponding to the wireless sensors, and sort the wireless sensors in the collaboration list according to the priority values. The steps are as follows: Combining the remaining transmission status of each cooperative sensor with its distance from the central sensor, and using predefined evaluation logic (e.g., higher priority value for better remaining transmission status and closer distance), a priority value is calculated for each cooperative sensor. Then, the wireless sensors in the cooperative list are rearranged according to their priority values ​​from highest to lowest, forming an ordered cooperative list. This allows for the priority selection of more suitable sensors during subsequent cooperative transmissions. The formula is as follows: ; Among them, P j S represents the priority value of sensor j in the collaborative list, a is a weighting coefficient used to adjust the importance ratio of remaining transmission status and distance. rem，j Score the remaining transmission state of sensor j.

[0027] S4. Set a protection transmission threshold. Enable collaborative transmission for the wireless transmitter by setting the protection transmission threshold and the remaining transmission status. Allocate collaborative transmission data to the wireless sensor based on the data transmission record and the collaborative list. While ensuring transmission security, initiate collaborative transmission and allocate data reasonably to avoid overloading individual sensors; The steps for S4 are as follows: S4.1 Set a protection transmission threshold based on the overall transmission status and data transmission records; Based on the overall sensor performance reflected by the comprehensive transmission status and problems occurring in the data transmission records (such as transmission failures due to overload, interruptions due to low battery, etc.), a protective transmission threshold is set. This threshold must ensure that the sensor can maintain basic operation after cooperative transmission is enabled, avoiding malfunctions or significant performance degradation due to cooperative transmission. The formula is as follows: ; Among them, T pt To protect the transmission threshold, S ct R is used to score the overall transmission status of the sensor. min'b' represents the lowest stable state value of the sensor in the historical transmission records, and 'b' is the weighting coefficient, reflecting the importance ratio between the overall transmission state and the historical lowest state.

[0028] S4.2. Combine the remaining transmission status of the wireless sensor with the protection transmission threshold for collaborative transmission analysis. If the remaining transmission status meets the protection transmission threshold requirements (indicating that the sensor has the conditions to participate in collaborative transmission), then collaborative transmission is enabled for the wireless sensor. Otherwise, if the remaining transmission status does not meet the protection transmission threshold requirements, then monitoring continues. S4.3 For wireless sensors that have enabled cooperative transmission, perform cooperative transmission data analysis based on the real-time transmission status and data transmission records to obtain the cooperative transmission data that the wireless sensor needs to send. For sensors that have enabled collaborative transmission, the total amount of data that needs to be transmitted through collaborative transmission is determined by analyzing their current real-time transmission status and historical data transmission records, thus clarifying the task scale of collaborative transmission. The formula is as follows: ; Among them, D xt For the amount of data that needs to be transferred collaboratively, D total S represents the total amount of data that the sensor currently needs to transmit. ss For the sensor's current real-time transmission capability, S ed This refers to the sensor's rated transmission capacity. S4.4. Combine the collaborative transmission data with the remaining transmission status of the wireless sensors in the collaborative list to allocate the collaborative transmission data, and determine the collaborative transmission data that the wireless sensors in the collaborative list need to receive.

[0029] Based on the remaining transmission status of each sensor in the collaborative list, the total amount of data to be collaboratively transmitted is allocated to the sensors in the list. During the allocation process, it must be ensured that after each sensor receives data, its remaining transmission status is still not lower than the protection transmission threshold. Finally, the specific amount of data that each collaborative sensor needs to receive is determined.

[0030] S4.4 When allocating data for coordinated transmission, the transmission state occupied will not cause the remaining transmission state to fall below the protection transmission threshold. Meanwhile, the wireless sensors that need to transmit data collaboratively send a portion of the data to be transmitted as collaborative transmission data to the wireless sensors in the collaborative list, and then the wireless sensors in the collaborative list send it to the data receiving end.

[0031] S5. The transmitted data is temporarily stored in the wireless sensor, and the transmitted data is verified by the data receiver. Based on the verification result, the data is deleted from the wireless sensor data.

[0032] To ensure the accuracy of data transmission and free up sensor storage space, thus avoiding resource waste, a traffic splitting and bidirectional verification mode is adopted to balance transmission efficiency and data accuracy. When the S5 data terminal performs verification, it copies the received data to the wireless sensor at the data source (creating a data copy and sending it back to the wireless sensor at the data source), and then compares the data (the comparison includes the integrity, accuracy, and consistency of key information to determine whether errors or loss occurred during the transmission of the data). If the data matches, the data is deleted in the wireless sensor; otherwise, if the data does not match, the wireless sensor retransmits the data until the data matches. After receiving collaborative transmission data, the wireless sensors in the collaborative list do not save it, but send it directly to the data receiver to reduce the occupation of storage resources and avoid transmission delays caused by data retention.

[0033] The second objective of this invention is to provide a data transmission and protection system for wireless sensors, including any one of the above-mentioned data transmission and protection methods for wireless sensors, comprising a collaborative screening unit, a data allocation unit, and a data verification unit. The collaborative screening unit is used to acquire the data transmission records of wireless sensors, as well as the parameter specifications and location data of the wireless sensors. It combines the parameter specifications with the location data to analyze the mutual transmission performance of the wireless sensors, and screens the wireless sensors for collaborative transmission based on the mutual transmission performance, thus establishing a collaborative list of wireless sensors. The data allocation unit is used to obtain the remaining transmission status of the wireless sensors, prioritize the wireless sensors in the collaboration list based on the remaining transmission status and location data, set a protection transmission threshold, enable collaborative transmission of the wireless transmitter through the protection transmission threshold and the remaining transmission status, and allocate collaborative transmission data to the wireless sensors based on the data transmission records and the collaboration list. The data verification unit is used to temporarily store the transmitted data in the wireless sensor and verify the transmitted data through the data receiving end. Based on the verification result, the data is deleted from the wireless sensor data.
