[0095] In this embodiment, the signal source can be any type of signal generator, and the working frequency band can cover the actual needs of the communication system.

[0096] In this embodiment, by fine adjustment of voltage or current, it ensures that the system can adapt to different load conditions and environmental changes, and realizes efficient and stable power output. The power supply adjustment module is used to realize accurate control of power output by adjusting voltage or current.

[0097] In this embodiment, the temperature sensor can accurately measure the environmental temperature and transmit real-time data to the data processing unit.

[0098] In this embodiment, the temperature compensation algorithm is responsible for calculating the compensation value according to the real-time temperature data and generating the control signal, and the specific steps are as follows:

[0099] 1. Real-time temperature data acquisition and processing: The data processing unit first needs to receive real-time temperature data from the temperature sensor. These data can come from various sensors such as thermocouples, RTD (Resistance Temperature Detector), etc., to ensure that the system can monitor temperature changes in real time. The data processing unit will filter and preprocess these data to remove noise and unstable factors, ensuring the accuracy and reliability of temperature information.

[0100] 2. Temperature compensation algorithm embedding: The temperature compensation algorithm is one of the core functions of the data processing unit. It establishes a mathematical model between temperature changes and performance deviations of the system. When the temperature changes, the performance of the system (such as the accuracy of the signal, the response of the device, etc.) may be affected. The compensation algorithm will calculate the compensation value that adapts to the current temperature in real time. For example, the output of some sensors may drift with temperature changes, and 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.

[0101] 3. Dynamic Adjustment and Real-Time Feedback: Based on real-time temperature data and compensation calculation results, the data processing unit continuously adjusts the compensation value to ensure the system's performance is at its best. For example, if the temperature rises, it may cause the device's response speed to change. The data processing unit will update the control signal in real time, so that the device can still operate efficiently under new temperature conditions. In addition, the data processing unit also transmits real-time feedback information to the control system for further optimization of other related operations, such as power adjustment, speed control, etc.

[0102] 4. Generation of Control Signals: The data processing unit not only calculates compensation values, but also generates 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. Control signals need to be accurately output to ensure that they match the compensation results, thereby avoiding system errors caused by temperature fluctuations. The data processing unit usually combines feedback mechanisms to ensure the accuracy and real-time nature of the control signals.

[0103] 5. Data Storage and Logging: In order to analyze and optimize the long-term performance of the system, the data processing unit usually records historical information of temperature data, compensation values and control signals. These data can be used for subsequent troubleshooting, performance evaluation and algorithm optimization, and can also be used by other modules for data analysis, trend prediction or alarm processing.

[0104] 6. Fault Detection and Exception Handling: The data processing unit also has certain fault detection and exception handling capabilities. If the temperature sensor fails or the compensation algorithm calculation deviates, 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.

[0105] 7. Collaboration with Other Modules: The data processing unit not only operates independently, but also needs to cooperate with other modules, such as the control unit, display module and communication module. It will interact with the control unit based on compensation calculation results and deliver compensation signals to actuators to adjust actual operation output.

[0106] In this embodiment, the multi-threaded control unit is responsible for parallel processing and scheduling of compensation tasks for each signal source, ensuring efficient operation of the system. The specific control method is as follows:

[0107] 1. Task Allocation and Scheduling: The multi-threaded 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 dynamically scheduled based on task priority, dependency and resource availability. This maximizes the utilization efficiency of system resources, avoids resource conflicts and ensures that each task can be completed within the scheduled time.

[0108] 2. Parallel processing and load balancing: Through multi-thread parallel processing, the control unit can execute multiple tasks simultaneously, significantly improving the processing speed of the system. For example, during the compensation process of signal sources, the compensation tasks of multiple signal sources can be run simultaneously in multiple threads without waiting for the previous task to complete. The control unit also monitors the load of each thread and balances the load by dynamically adjusting the allocation of tasks to prevent overloading of a thread, causing delays or low efficiency.

[0109] 3. Resource management and optimization: In order to ensure 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 allocation strategy of resources through resource monitoring algorithms to avoid excessive competition or waste of resources. The control unit can allocate critical resources based on the needs of different signal source compensation tasks to ensure smooth operation of the system under high load.

[0110] 4. Task synchronization and communication: In a multi-threaded environment, different threads may need to share data or results, and the multi-thread control unit manages task synchronization and communication to ensure data consistency and avoid race conditions and deadlocks. For example, some tasks may depend on the results of other threads, and the control unit coordinates the execution order of these threads to ensure the smooth completion of tasks.

[0111] 5. Fault handling and fault tolerance: The multi-thread control unit also needs to have certain fault tolerance when processing parallel tasks. If a thread fails or encounters an exception, the control unit can detect it in time and take appropriate measures such as rescheduling tasks or restarting the thread to ensure the robustness and stability of the system.

[0112] 6. Dynamic adjustment and adaptive ability: According to the current load 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 thread. For example, when the system load is low, the control unit may choose to reduce the number of threads to save resources; when the load is high, it will increase the number of threads to ensure that tasks are completed on time.

[0113] This application uses multi-thread technology and advanced temperature compensation algorithms to propose an innovative signal source compensation device and method, solving the problems of low precision and response delay in traditional compensation methods. This technology not only improves the stability of the signal source, but also greatly improves the reliability of the communication system, and is suitable for various communication equipment with high power accuracy requirements, with wide application prospects.

[0114] The application further provides a device for compensating signal sources by using multi-thread, which comprises a temperature data acquisition module, a compensation quantity information acquisition module, an adjustment module and a compensation instruction generation module.

[0115] The temperature data acquisition module is used for acquiring temperature data of environments where different signal sources are located respectively by using a multi-thread mechanism, and the temperature data is acquired by using a temperature sensor.

[0116] The compensation quantity information acquisition module is used for calculating compensation quantity information corresponding to each temperature data respectively by using a temperature compensation algorithm, wherein one compensation quantity information corresponds to temperature data of an environment where one signal source is located.

[0117] The compensation instruction generation module is used for generating corresponding compensation instructions for each compensation quantity information respectively according to the compensation quantity information.
