Description

Technical Field

[0001] The invention relates to the field of amplifiers, and in particular to a heat dissipation control method and a control system for a microwave power amplifier. Background Art

[0002] In modern wireless communication systems, microwave power amplifiers are key components, and their performance is directly related to the coverage, signal quality, and system stability of the communication system. With the rapid development of communication technology, the operating frequency and output power of microwave power amplifiers are constantly increasing, which leads to a sharp increase in the heat generated during operation. Excessive temperature will not only reduce the efficiency of the power amplifier and shorten its service life, but may also cause signal distortion and affect communication quality. Therefore, effectively controlling the heat dissipation of microwave power amplifiers has become an important issue in improving the performance and reliability of communication systems.

[0003] Traditional microwave power amplifier heat dissipation control methods mainly rely on the combination of passive heat dissipation (such as heat sinks, fans, etc.) and active heat dissipation (such as liquid cooling systems) technologies, but these methods often lack intelligence and adaptability, and it is difficult to dynamically adjust the heat dissipation strategy according to the actual working state of the power amplifier. Especially in complex and changeable communication environments, the load, operating frequency and output power of microwave power amplifiers will change frequently, and fixed heat dissipation strategies often cannot meet actual needs, resulting in poor heat dissipation effects or energy waste.

[0004] In addition, traditional heat dissipation control methods usually ignore the intrinsic relationship between microwave power amplifier performance loss and heat dissipation effect, and do not fully utilize the performance parameters of the power amplifier (such as transmission power, power consumption, temperature, etc.) to optimize the heat dissipation strategy. This not only limits the accuracy and efficiency of heat dissipation control, but may also cause the power amplifier to be in a non-optimal working state for a long time, affecting its long-term stability and reliability. Summary of the invention

[0005] The purpose of the present invention is to overcome the deficiencies of the prior art and provide a method for controlling heat dissipation of a microwave power amplifier, comprising the following steps: Step 1: The terminal test server generates a test control container and connects it to the test module.

The calibration module compensates the heat dissipation module according to the relationship between the initial heat dissipation power and the heat dissipation performance of the heat dissipation module, obtains the relationship between the heat dissipation power and the heat dissipation performance after compensation, and then proceeds to step 5; Step 5: According to the heat dissipation performance corresponding to the transmission power, the compensated heat dissipation power of the heat dissipation performance corresponding to the transmission power is matched in the relationship between the compensated heat dissipation power and the heat dissipation performance, and the compensated heat dissipation power of the heat dissipation performance corresponding to the transmission power and the corresponding transmission power constitute a power amplifier heat dissipation strategy; Step six, dissipate heat for the power amplifier according to the power amplifier heat dissipation strategy, and complete heat dissipation control of the power amplifier.

[0022] The test module tests the heat dissipation module of the microwave power amplifier to obtain the performance attenuation of the heat dissipation module, including: According to the set heat dissipation performance parameters, the heat dissipation performance corresponding to the heat dissipation power is obtained. According to the relationship between the standard heat dissipation power and the corresponding heat dissipation performance, the heat dissipation power difference under the same heat dissipation performance is obtained, and the performance attenuation of the heat dissipation module is obtained.

[0023] The method of obtaining the performance loss of the microwave power amplifier according to the relationship between the initial power consumption and the transmission power of the microwave power amplifier includes: The performance loss of the microwave power amplifier is obtained according to the difference between the power consumption of the microwave power amplifier and the initial power consumption of the microwave power amplifier and the ratio of the power consumption of the microwave power amplifier to the initial power consumption of the microwave power amplifier under the same transmission power.

[0024] The method of obtaining a temperature difference according to the relationship between the transmission power and the temperature of the microwave power amplifier and the relationship between the standard transmission power and the temperature of the microwave power amplifier, and obtaining the corrected heat dissipation power according to the temperature difference, comprises: The relationship between the standard transmission power and the temperature of the microwave power amplifier is the relationship between different transmission powers and the corresponding temperature of the microwave power amplifier when the performance of the microwave power amplifier is not lost; Under the same transmission power, the temperature difference of the microwave power amplifier in the relationship between the microwave power amplifier temperature and the standard transmission power and the microwave power amplifier temperature is obtained, and the corrected heat dissipation power is obtained according to the temperature difference of the microwave power amplifier and the heat dissipation performance of the heat dissipation module.

[0027] like Figure 2 As shown, a microwave power amplifier heat dissipation control system, applying the microwave power amplifier heat dissipation control method, includes a terminal test server, a data processing module, a communication module, a test module, a data acquisition module, an alarm module and a display module; The communication module, test module, data acquisition module, alarm module and display module are respectively connected to the data processing module; the terminal test server is communicatively connected to the communication module.

[0028] like Figure 3 As shown, the data acquisition module includes a power consumption data acquisition module and a temperature data acquisition module; the power consumption data acquisition module and the temperature data acquisition module are respectively connected to the data processing module.

[0029] Specifically, the microwave power amplifier heat dissipation control method of the present invention comprises the following steps: Step 1: The terminal test server generates a test control container and connects it to the test module. The test module first conducts a comprehensive test on the microwave power amplifier. By collecting power consumption data and temperature data at different transmission powers, it establishes a curve between the transmission power and power consumption of the microwave power amplifier and a curve between the transmission power and the temperature of the microwave power amplifier. This step is the basis for subsequent analysis and ensures the accuracy and reliability of the data. At the same time, the test module also conducts a preliminary test on the heat dissipation module of the microwave power amplifier to evaluate its heat dissipation performance in preparation for subsequent performance attenuation measurement and compensation.

[0030] Step 2: Calculate the performance loss of the microwave power amplifier based on the relationship between the initial power consumption and the transmission power of the microwave power amplifier obtained in step 1. The specific method is to calculate the difference between the current power consumption of the microwave power amplifier and the initial power consumption (i.e., the power consumption when the performance is not lost) for each transmission power point, and compare it with the initial power consumption to obtain the performance loss percentage. If the performance loss is greater than the set performance loss threshold (such as 5%), an alarm message is issued to prompt the user to perform maintenance or replacement; otherwise, proceed to step 3.

[0031] Step 3: Analyze the relationship between the transmission power and the temperature of the microwave power amplifier, and compare it with the relationship between the standard transmission power and the temperature of the microwave power amplifier (i.e., the relationship when the performance is not lost), and obtain the temperature difference of the microwave power amplifier at different transmission powers. According to these temperature differences and the heat dissipation performance of the heat dissipation module (including the fan speed if it is fan cooling, the coolant flow rate if it is liquid cooling, etc.), calculate the corrected heat dissipation power, that is, the heat dissipation power required to compensate for the performance loss. Then, add the corrected heat dissipation power to the standard heat dissipation power corresponding to the transmission power to obtain the corrected heat dissipation power corresponding to the transmission power, and evaluate the heat dissipation performance of the microwave power amplifier at different transmission powers based on this, and proceed to step 5.

[0032] Step 4: The test module further conducts detailed tests on the heat dissipation module of the microwave power amplifier, and calculates the performance attenuation of the heat dissipation module by comparing the heat dissipation performance under the standard heat dissipation power and the current heat dissipation power. This data reflects the degree of decline in the heat dissipation capacity of the heat dissipation module due to factors such as aging and wear. Subsequently, the performance attenuation is sent to the calibration module. The calibration module compensates the heat dissipation module according to the relationship between the initial heat dissipation power and the heat dissipation performance of the heat dissipation module, that is, adjusts the corresponding relationship between the heat dissipation power and the heat dissipation performance to offset the impact of performance attenuation, and obtains the relationship between the heat dissipation power and the heat dissipation performance after compensation, and then proceeds to step five.

[0033] Step 5: Based on the results of step 3 and step 4, for each transmit power point, the corresponding compensated heat dissipation power is matched in the relationship between the compensated heat dissipation power and the heat dissipation performance according to the heat dissipation performance of the microwave power amplifier (considering the heat dissipation requirements after performance loss). In this way, the compensated heat dissipation power corresponding to the heat dissipation performance of different transmit powers is obtained, which together with the corresponding transmit power constitutes the power amplifier heat dissipation strategy. This strategy ensures that the microwave power amplifier can obtain just the right heat dissipation support under different working conditions.

[0034] Step 6: Finally, according to the power amplifier heat dissipation strategy, the control system adjusts the working state of the heat dissipation module (such as fan speed, coolant flow, etc.) in real time to accurately dissipate heat for the power amplifier. At the same time, the system can continuously monitor the working state and heat dissipation effect of the microwave power amplifier, and automatically adjust the heat dissipation strategy when necessary to achieve closed-loop control and ensure the effectiveness and stability of heat dissipation control.

[0035] The specific implementation method of the test module for testing the microwave power amplifier is as follows: The test module collects the power consumption and temperature data of the microwave power amplifier at different transmission powers through the data acquisition module (including the power consumption data acquisition module and the temperature data acquisition module). The power consumption data acquisition module uses a high-precision power meter to measure the input power and output power of the power amplifier and calculates the power consumption; the temperature data acquisition module directly measures the operating temperature of the power amplifier through a temperature sensor.

[0036] The specific implementation method of the test module for testing the heat dissipation module of the microwave power amplifier is as follows: The performance attenuation test of the heat dissipation module is mainly based on the change of heat dissipation efficiency. During the test, a series of standard heat dissipation power values ​​are first set, and the microwave power amplifier temperature that the heat dissipation module can maintain under these powers is measured. Then, the heat dissipation performance is compared with that during actual operation, and the performance attenuation of the heat dissipation module is obtained by calculating the difference in the required heat dissipation power under the same heat dissipation effect.

[0037] The specific implementation method of obtaining the performance loss of the microwave power amplifier according to the relationship between the initial power consumption and the transmission power of the microwave power amplifier is: The performance loss is calculated using the relative value comparison method. For each transmit power point, the difference between the current power consumption and the initial power consumption (usually measured when the power amplifier leaves the factory or when the performance is optimal) is calculated, and the difference is divided by the initial power consumption to obtain the performance loss percentage. This method can intuitively reflect the degree of degradation of the power amplifier performance over time.

[0038] The specific implementation method of correcting the heat dissipation power according to the temperature difference is as follows: The relationship between the standard transmission power and the temperature of the microwave power amplifier is determined by experiments or data provided by the manufacturer, and represents the operating temperature characteristics of the power amplifier under ideal conditions. In practical applications, the temperature difference is obtained by comparing the current operating temperature with the standard temperature. Then, based on the heat dissipation performance of the heat dissipation module, the additional heat dissipation power required to eliminate this temperature difference is calculated, that is, the corrected heat dissipation power.

[0039] The specific implementation method of the calibration module compensating the heat dissipation module is as follows: The calibration module corrects the original relationship between heat dissipation power and heat dissipation performance according to the performance attenuation of the heat dissipation module. Specifically, based on the original relationship curve, the heat dissipation power value is adjusted upward according to the proportion of performance attenuation to ensure that the heat dissipation module can provide sufficient heat dissipation capacity under the same heat dissipation performance requirements.

[0040] The microwave power amplifier heat dissipation control system of the present invention comprises a terminal test server, a data processing module, a communication module, a test module, a data acquisition module (including a power consumption data acquisition module and a temperature data acquisition module), an alarm module and a display module. Among them, the communication module is responsible for data transmission between the terminal test server and the local system; the test module is responsible for executing specific test tasks; the data acquisition module is responsible for collecting the working parameters of the microwave power amplifier and the heat dissipation module; the data processing module is responsible for data processing, analysis and strategy generation; the alarm module issues an alarm when an abnormal situation is detected; and the display module is used to display the test results and heat dissipation strategy. Example

[0041] The microwave power amplifier used in a communication base station requires heat dissipation control to ensure its stable operation under different transmission powers.

[0042] Specific steps: Step 1: The terminal test server generates a test control container and connects it to the test module in the base station. The test module conducts a comprehensive test on the microwave power amplifier through the data acquisition module (including the power consumption data acquisition module and the temperature data acquisition module). The power consumption data acquisition module uses a high-precision power meter to measure the input power and output power of the power amplifier at multiple transmission power points (such as 10W, 20W, 30W, etc.) and calculates the corresponding power consumption. The temperature data acquisition module measures the operating temperature at these transmission powers through the temperature sensor installed on the power amplifier.

[0043] Based on these data, the relationship curves between the transmission power and power consumption and the relationship curves between the transmission power and temperature of the microwave power amplifier were established.

[0044] At the same time, a preliminary test was conducted on the heat dissipation module (assuming fan cooling), and the heat dissipation effect at different fan speeds was recorded.

[0045] Step 2: The data processing module calculates the performance loss percentage at each transmit power point based on the power consumption data obtained in step 1. For example, at 20W transmit power, the current power consumption is 3% higher than the initial power consumption, which is lower than the set performance loss threshold of 5%, so no alarm information is issued.

[0046] Step 3: The relationship between transmission power and temperature was analyzed and compared with the standard relationship. It was found that at 30W transmission power, the actual operating temperature of the microwave power amplifier was 5°C higher than the standard temperature. Based on the heat dissipation performance of the fan heat dissipation module (the relationship between fan speed and heat dissipation effect), the additional heat dissipation power required to compensate for the 5°C temperature difference was calculated, that is, the corrected heat dissipation power. The corrected heat dissipation power was added to the standard heat dissipation power at 30W transmission power to obtain the corrected heat dissipation power.

[0047] Step 4: The test module conducted a detailed test on the fan cooling module and found that due to the aging of the fan, its cooling efficiency decreased by 10%. Based on this performance attenuation, the calibration module corrected the original relationship between cooling power and cooling performance, and increased the cooling power value required for the same cooling effect.

[0048] Step 5: For each transmission power point, according to the heat dissipation performance of the microwave power amplifier (considering the performance loss and the requirements after the heat dissipation module is attenuated), the corresponding compensated heat dissipation power is matched in the relationship between the compensated heat dissipation power and the heat dissipation performance. This constitutes the heat dissipation strategy of the power amplifier. For example, at a transmission power of 30W, the fan needs to work at a specific speed to ensure the heat dissipation effect.

[0049] Step 6: The control system adjusts the fan speed in real time according to the heat dissipation strategy to accurately dissipate heat for the microwave power amplifier. The system continuously monitors the working status and heat dissipation effect of the power amplifier, and automatically adjusts the fan speed when necessary to ensure the effectiveness and stability of heat dissipation control.
