[0022] In this embodiment, obtaining the temperature compensation value according to the temperature difference information through the following formula includes: COE = C * T3; where COE is the temperature compensation value, C is the temperature coefficient, and T3 is the temperature difference information.

[0023] In this embodiment, the temperature coefficient (C) is a key parameter affecting the signal source compensation process, which represents the influence degree of temperature on the signal source performance. This coefficient is usually stored in a configuration file, which is measured through experiments in a temperature chamber environment. The specific method for obtaining the temperature coefficient is as follows: 1. The power at a test temperature of 0°C is Power1, and the power at a test temperature of 50°C is Power2.

[0024] In this embodiment, obtaining the compensation amount information according to the temperature compensation value includes: Obtaining the frequency offset; Obtaining the power offset; Obtaining the compensation amount information according to the frequency offset and the power offset.

[0030] In this embodiment, the signal source can be any type of signal generator, and the operating frequency band can cover the actual requirements of the communication system.

[0031] In this embodiment, by finely adjusting the voltage or current, a power supply adjustment module is adopted to ensure that the system can adapt to different load conditions and environmental changes, and achieve efficient and stable power output by precisely controlling the power output by adjusting the voltage or current.

[0032] In this embodiment, the temperature sensor can accurately measure the ambient temperature and transmit the real-time data to the data processing unit.

[0033] In this embodiment, the temperature compensation algorithm is responsible for calculating the compensation value according to the real-time temperature data and generating a control signal. The specific steps are as follows: 1. Real-time temperature data acquisition and processing: The data processing unit first needs to receive the real-time temperature data from the temperature sensor. These data can be from a variety of sensors, such as thermocouples, RTDs (resistance temperature detectors), etc., to ensure that the system can monitor the temperature change in real time. The data processing unit will filter and preprocess these data to remove noise and unstable factors to ensure the accuracy and reliability of the temperature information.

[0034] 2. Embedding of Temperature Compensation Algorithm: The temperature compensation algorithm is one of the core functions of the data processing unit. It establishes the relationship between temperature changes and the performance deviation of the system through a mathematical model. When the temperature changes, the performance of the system (such as signal accuracy, device response, etc.) may be affected. The compensation algorithm will calculate the compensation value suitable for the current temperature in real time. For example, the output of some sensors may drift with temperature changes. The temperature compensation algorithm will adjust the compensation value according to the relationship between temperature and sensor output to ensure the accuracy and stability of the measurement results.

[0035] 3. Dynamic Regulation and Real - time Feedback: Based on real - time temperature data and compensation calculation results, the data processing unit will continuously adjust the compensation value to ensure that the system performance is in an optimal state. For example, an increase in temperature may cause a change in the response speed of the device. The data processing unit will immediately update the control signal so that the device can still operate efficiently under the new temperature conditions. In addition, the data processing unit will also transmit real - time feedback information to the control system for further optimizing other related operations, such as power regulation, speed control, etc.

[0036] 4. Generation of Control Signals: The data processing unit not only needs to calculate the compensation value but also generate control signals based on these calculation results. These signals may be used to adjust different parts of the system, such as adjusting current, voltage, frequency, or other physical parameters. The control signals need to be output accurately to ensure they match the compensation results, thus avoiding system errors caused by temperature fluctuations. The data processing unit usually combines a feedback mechanism to ensure the accuracy and real - time nature of the control signals.

[0037] 5. Data Storage and Logging: To analyze and optimize the long - term performance of the system, the data processing unit usually also records historical information of temperature data, compensation values, and control signals. These data can be used for subsequent fault troubleshooting, performance evaluation, and algorithm optimization, and can also be used by other modules for data analysis, trend prediction, or alarm processing.

[0038] 6. Fault Detection and Exception Handling: The data processing unit also has certain capabilities for fault detection and exception handling. If the temperature sensor fails or there is a deviation in the compensation algorithm calculation, the data processing unit will automatically detect and take appropriate measures, such as switching to a backup sensor, resetting the compensation value, or sending an alarm signal, to ensure the normal operation of the system is not affected.

[0039] 7. Collaboration with Other Modules: The data processing unit not only operates independently but also needs to collaborate with other modules, such as the control unit, display module, and communication module, etc. It will interact with the control unit according to the compensation calculation results, transmit the compensation signal to the actuator, and adjust the actual operation output.

[0040] In this embodiment, the multi-thread control unit is responsible for parallel processing and scheduling of the compensation tasks for each signal source to ensure the efficient operation of the system. The specific control method is as follows: 1. Task Allocation and Scheduling: The multi-thread control unit is responsible for allocating different signal source compensation tasks to multiple processing threads. It ensures that each task is correctly assigned to the most suitable processing unit and performs dynamic scheduling based on the task's priority, dependencies, and resource availability. This can maximize the utilization efficiency of system resources, avoid resource conflicts, and ensure that each task can be completed within the scheduled time.

[0041] 2. Parallel Processing and Load Balancing: Through multi-thread parallel processing, the control unit can execute multiple tasks simultaneously, significantly improving the system's processing speed. For example, during the compensation process of signal sources, the compensation tasks of multiple signal sources can run simultaneously in multiple threads without waiting for the previous task to complete. The control unit also monitors the load conditions of each thread and achieves load balancing by dynamically adjusting the task allocation to prevent a certain thread from being overloaded, resulting in delays or low efficiency.

[0042] 3. Resource Management and Optimization: To ensure the efficient operation of the system, the multi-thread control unit needs to effectively manage the allocation of processor, memory, and other hardware resources. It dynamically adjusts the resource allocation strategy through resource monitoring algorithms to avoid excessive resource competition or idle waste. The control unit can preferentially allocate key resources according to the requirements of different signal source compensation tasks to ensure the stable operation of the system under high load.

[0043] 4. Task Synchronization and Communication: In a multi-thread environment, different threads may need to share data or results. At this time, the multi-thread control unit manages task synchronization and communication to ensure data consistency and avoid problems such as race conditions and deadlocks. For example, some tasks may depend on the results completed by other threads, and the control unit will coordinate the execution order of these threads to ensure the smooth completion of tasks.

[0044] 5. Fault Handling and Fault Tolerance: When processing parallel tasks, the multi-thread control unit also needs to have a certain degree of fault tolerance. If a certain thread fails or has an exception, the control unit can detect it in time and take corresponding measures, such as rescheduling tasks or restarting the thread, to ensure the robustness and stability of the system.

[0045] 6. Dynamic Adjustment and Adaptive Ability: According to the current load condition of the system or changes in the external environment, the multi-thread control unit can dynamically adjust the task scheduling strategy and the working mode of the threads. For example, when the system load is low, the control unit may choose to reduce the number of threads to save resources; while when the load is high, it will increase the number of threads to ensure that tasks are completed on time.

[0046] By adopting multi-thread technology and advanced temperature compensation algorithms, this application proposes an innovative signal source compensation device and method, which solves the problems of low accuracy and response delay existing in traditional compensation methods. While improving the stability of the signal source, this technology also greatly enhances the reliability of the communication system. It is applicable to various communication devices with high requirements for power accuracy and has broad application prospects.

[0047] This application also provides a device for compensating a signal source using multi-threads.

Among them, The temperature data acquisition module is used to respectively acquire the temperature data of the environments where different signal sources are located through a multi-thread mechanism, and the temperature data is acquired through temperature sensors.

Among them, one compensation amount information corresponds to the temperature data of the environment where a signal source is located. The compensation instruction generation module is used to respectively generate corresponding compensation instructions for each compensation amount information according to the compensation amount information. The adjustment module is used to adjust the power output of the corresponding signal source according to the generated compensation instructions.
