Description

Technical Field

[0001] The present invention relates to the field of microwave amplifiers, and more specifically, to a microwave amplifier control method and system. Background Art

[0002] Microwave signal base stations are used to radiate and transmit microwave signals to the external environment. However, in the actual signal propagation process, there are objects such as buildings or vegetation in the external environment, which will block or attenuate the microwave signals. In order to ensure the normal radiation transmission of microwave signals, microwave amplifiers are usually set in microwave signal base stations to amplify the power of microwave signals. This can ensure that the microwave signals will not be unable to be transmitted to the corresponding receiving terminals due to intensity attenuation during the subsequent radiation transmission process. It can be seen that the existing microwave amplifiers only perform a uniform amplification processing on microwave signals. They cannot perform differentiated amplification processing on different types of microwave signals, and they cannot effectively and timely dissipate the heat generated by the microwave amplifiers during operation, thereby affecting the stability and reliability of the operation of the microwave amplifiers. Summary of the invention

[0003] In view of the defects in the prior art, the present invention provides a control method and system for a microwave amplifier, which instructs the microwave amplifier to identify and distinguish received microwave signals, thereby performing differentiated power amplification on uplink microwave signals and downlink microwave signals. Meanwhile, during the power amplification operation of the microwave amplifier, the working state of each level of the amplification circuit of the microwave amplifier is adjusted according to the noise component and power gain state of the output signal of each level of the amplification circuit of the microwave amplifier, and the heat dissipation intensity of the radiator can be controlled according to the real-time working temperature of the microwave amplifier, thereby restoring the working temperature of the microwave amplifier to a preset temperature state. In this way, differentiated amplification processing can be performed on different types of microwave signals, and the heat generated by the microwave amplifier during operation can be effectively and timely actively dissipated, thereby improving the stability and reliability of the operation of the microwave amplifier.

[0004] In order to achieve the above object, the present invention adopts the following technical solutions:

[0005] In a first aspect, the present invention provides a microwave amplifier control method, comprising the following steps:

[0006] S1: The microwave amplifier receives a microwave signal from a signal source and sends the microwave signal to a microwave amplification link for power amplification;

[0007] S2: During the process of power amplification, collect the output signals of each stage of the amplification circuit included in the microwave amplifier, perform noise reduction processing on each stage of the output signal, analyze each stage of the output signal, calculate the real-time power gain of each stage of the amplification circuit, and adjust the driving power supply level for each stage of the amplification circuit according to the real-time power gain of each stage of the amplification circuit;

[0008] S3: During the process of power amplification, collect the real-time operating temperatures of different regions of the microwave amplifier, and control the heat dissipation intensity of the radiator connected to the microwave amplifier according to the real-time operating temperatures of different regions until the real-time operating temperature of the microwave amplifier returns to the preset temperature;

[0009] S4: Feed back the microwave signal after power amplification to the signal source.

[0010] In a specific example, the step S1 includes:

[0011] S11: The microwave amplifier performs signal scanning and searching to receive microwave signals from the signal source;

[0012] S13: Identify the microwave base station address corresponding to the received microwave signal. If the microwave base station address exists in the preset microwave base station address whitelist, retain the microwave signal; otherwise, delete the microwave signal;

[0013] S15: Send the retained microwave signals into the microwave amplification link for power amplification.

[0014] In a specific example, the step S2 includes:

[0015] S21: During the process of power amplification, collect the output signals of each stage of the amplification circuit included in the microwave amplifier;

[0016] S23: Identify the noise components of each stage of the output signal to determine the signal-to-noise ratio of each stage of the output signal. Compare the signal-to-noise ratio of each stage of the output signal with the preset signal-to-noise ratio threshold. If the signal-to-noise ratio of a certain stage of the output signal is greater than or equal to the preset signal-to-noise ratio threshold, perform noise reduction processing on the corresponding stage of the output signal; otherwise, do not perform noise reduction processing on the output signal;

[0017] S25: Obtain the real-time power gain of the output signals measured by each stage of the amplification circuit for every two adjacent times, and calculate the difference between the real-time power gains measured for every two adjacent times. Among them,

[0018] if the difference is within the preset difference range, keep the driving power supply level applied to the corresponding stage of the amplification circuit unchanged; if the difference is not within the preset difference range, adjust the amplitude of the driving power supply level applied to the corresponding stage of the amplification circuit until the difference is within the preset difference range.

[0019] In a specific example, step S3 includes:

[0020] S31: During the process of power amplification, temperature sensors distributed in different regions of the microwave amplifier respectively collect the real-time operating temperatures of the corresponding regions;

[0021] S33: Determine whether the real-time operating temperature collected by each temperature sensor exceeds a preset temperature threshold; if the real-time operating temperature values collected by more than half of all the temperature sensors exceed the preset temperature threshold, the real-time operating temperature of the microwave amplifier is in a high state; if the real-time operating temperature values collected by less than half of all the temperature sensors exceed the preset temperature threshold, the real-time operating temperature of the microwave amplifier is in a low state;

[0022] S35: When the real-time operating temperature of the microwave amplifier is in a high state, the radiator connected to the microwave amplifier adjusts its heat dissipation intensity until the real-time operating temperature of the microwave amplifier returns to the preset temperature state; when the real-time operating temperature of the microwave amplifier is in a low state, the radiator connected to the microwave amplifier dissipates heat normally.

[0023] In a second aspect, the present invention provides a microwave amplifier control system, including: a microwave signal acquisition and amplification processing module, a microwave signal noise reduction and gain adjustment module, and a microwave amplifier heat dissipation adjustment module, wherein,

[0024] The microwave signal acquisition and amplification processing module is used to receive microwave signals from a signal source, send the microwave signals into a microwave amplification link for power amplification, and feedback the power-amplified microwave signals back to the signal source;

[0025] The microwave signal noise reduction and gain adjustment module is used to collect the output signals of each stage of the amplification circuit included in the microwave amplifier during the process of power amplification of the microwave signals, and perform noise reduction processing on each stage of the output signals; analyze the output signals, calculate the real-time power gain of each stage of the amplification circuit, and adjust the driving power supply level of each stage of the amplification circuit according to the real-time power gain of each stage of the amplification circuit;

[0026] The microwave amplifier heat dissipation adjustment module is used to collect the real-time operating temperatures of different regions of the microwave amplifier during the process of power amplification of the microwave signals, and control the heat dissipation intensity of the radiator connected to the microwave amplifier until the operating temperature of the microwave amplifier returns to the preset temperature state.

[0027] In a specific example, the microwave signal acquisition and processing module receives microwave signals from a signal source through signal scanning and searching, identifies the microwave base station address corresponding to the received microwave signals. If the microwave base station address exists in a preset microwave base station address whitelist, the microwave signals are retained; otherwise, the microwave signals are deleted.

[0028] Then, the retained microwave signals are sent into a microwave amplification link for power amplification, and the power-amplified microwave signals are fed back to the signal source.

[0029] In a specific example, the microwave signal noise reduction and gain adjustment module identifies the noise components of each stage of output signals, thereby determining the signal-to-noise ratio of each output signal, and compares the signal-to-noise ratio of each stage of output signals with a preset signal-to-noise ratio threshold. If the signal-to-noise ratio of the output signal is greater than or equal to the preset signal-to-noise ratio threshold, noise reduction processing is performed on the output signal of the corresponding stage; otherwise, no noise reduction processing is performed on the output signal.

[0030] The microwave signal noise reduction and gain adjustment module calculates the difference between two real-time power gains of the output signals measured twice adjacent to each stage of the amplification circuit. If the difference is within a preset difference range, the driving power supply level applied to the corresponding stage of the amplification circuit is kept unchanged; if the difference is not within the preset difference range, the driving power supply level applied to the corresponding stage of the amplification circuit is adjusted until the difference is within the preset difference range.

[0031] In a specific example, the microwave amplifier heat dissipation adjustment module is used to obtain the real-time operating temperatures of corresponding regions collected by a number of temperature sensors distributed in different regions of the microwave amplifier.

[0032] The microwave amplifier heat dissipation adjustment module is used to determine whether the real-time operating temperature collected by each temperature sensor exceeds a preset temperature threshold. If the real-time operating temperature values collected by more than half of all the temperature sensors exceed the preset temperature threshold, the real-time operating temperature of the microwave amplifier is in a high state; if the real-time operating temperature values collected by less than half of all the temperature sensors exceed the preset temperature threshold, the real-time operating temperature of the microwave amplifier is in a low state.

[0033] When the real-time operating temperature of the microwave amplifier is in a high state, the heat sink connected to the microwave amplifier adjusts its heat dissipation intensity until the real-time operating temperature of the microwave amplifier returns to the preset temperature state; when the real-time operating temperature of the microwave amplifier is in a low state, the heat sink connected to the microwave amplifier dissipates heat normally.

[0034] The beneficial effects of the present invention are as follows:

[0035] Compared with the prior art, the microwave amplifier control method and system identify and distinguish the received microwave signals by instructing the microwave amplifier, so as to perform differentiated power amplification for the uplink microwave signals and the downlink microwave signals. At the same time, during the process of the microwave amplifier performing power amplification operations, according to the noise components and power gain states of the output signals of each stage of the amplification circuit of the microwave amplifier, the working states of each stage of the amplification circuit of the microwave amplifier are adjusted, and the heat dissipation intensity of the radiator can also be controlled according to the real-time working temperature of the microwave amplifier, so that the working temperature of the microwave amplifier is restored to the preset temperature state. In this way, differentiated amplification processing can be performed for different types of microwave signals, and the heat generated by the microwave amplifier during operation can be effectively and actively dissipated in a timely manner, thereby improving the stability and reliability of the operation of the microwave amplifier.

Obviously, the drawings in the following description are only some embodiments of the present invention, and those of ordinary skill in the art can obtain other drawings based on these drawings without creative efforts.

[0038] Figure 2 Show a schematic diagram of a microwave amplifier control system according to an embodiment of the present invention. DETAILED DESCRIPTION OF THE EMBODIMENTS

[0039] To make the technical solutions and advantages of the present invention clearer, the embodiments of the present invention will be further described in detail below with reference to the drawings.

[0040] The first embodiment of the present invention provides a microwave amplifier control method, as Figure 1 shown, including the following steps:

[0041] S1: The microwave amplifier receives microwave signals from a signal source and sends the microwave signals into a microwave amplification link for power amplification. Among them, the signal source can be a base station antenna;

[0042] S2: During the process of power amplification, collect the output signals of each stage of the amplification circuit included in the microwave amplifier, perform noise reduction processing on the output signals of each stage of the amplification circuit, analyze the output signals of each stage of the amplification circuit, calculate the real-time power gain of each stage of the amplification circuit, and adjust the drive power supply level for each stage of the amplification circuit according to the real-time power gain of each stage of the amplification circuit;

[0043] S3: during the power amplification process, collecting the real-time operating temperatures of different regions of the microwave amplifier, and controlling the heat dissipation intensity of the heat sink connected to the microwave amplifier according to the real-time operating temperatures of the different regions, until the real-time operating temperature of the microwave amplifier returns to a preset temperature;

[0044] S4: Feeding back the microwave signal after power amplification to the signal source.

[0045] The microwave amplifier control method can adjust the working state of each level of the amplifying circuit of the microwave amplifier according to the noise component and power gain state of the output signal of each level of the amplifying circuit of the microwave amplifier during the power amplification operation of the microwave amplifier, and can also control the heat dissipation intensity of the radiator according to the real-time working temperature of the microwave amplifier, so that the working temperature of the microwave amplifier is restored to a preset temperature state, so that differentiated amplification processing can be performed for different types of microwave signals, and the heat generated by the microwave amplifier during the working process can be effectively and timely actively dissipated, thereby improving the stability and reliability of the operation of the microwave amplifier.

[0046] In a specific embodiment, the step S1 includes:

[0047] S11: the microwave amplifier performs signal scanning and searching to receive a microwave signal from a signal source;

[0048] S13: Identify the microwave base station address corresponding to the received microwave signal, and if the microwave base station address exists in a preset microwave base station address whitelist, retain the microwave signal; otherwise, delete the microwave signal;

[0049] S15: Send the retained microwave signal to a microwave amplification link for power amplification.

[0050] The received microwave signals are identified and differentiated by indicating the microwave amplifier, so as to perform differentiated power amplification for the uplink microwave signals and the downlink microwave signals;

[0051] The microwave amplifier is used to amplify the power of microwave signals from a signal source, thereby improving the transmission persistence of microwave signals and preventing significant attenuation of microwave signals during transmission. During operation, the microwave amplifier searches for microwave signals from the signal source in a signal scanning and searching manner. When the microwave amplifier searches for and receives a microwave signal from a certain signal source, the microwave amplifier can obtain the base station address of the corresponding signal source from the microwave signal. Then, the base station address is compared with a preset white list of base station addresses. Only the microwave signals from the signal sources corresponding to the preset white list of base station addresses can continue to be retained in the microwave amplifier; otherwise, the microwave signal is deleted. Among them, the preset white list of base station addresses can include the base station addresses corresponding to several authorized signal sources. Through the above signal scanning and searching method, a microwave amplifier can be simultaneously matched with multiple signal sources and perform corresponding microwave signal amplification processing. Such a one-to-many signal amplification method can improve the usage efficiency of the microwave amplifier, and through the above white list comparison method, the security of microwave signal amplification processing can be improved.

[0052] In a specific embodiment, step S2 includes:

[0053] S21: During the process of power amplification, collect the output signals of each stage of the amplification circuit included in the microwave amplifier;

[0054] S23: Identify the noise components of each stage of the output signal, thereby determining the signal-to-noise ratio of each stage of the output signal. Compare the signal-to-noise ratio of each stage of the output signal with a preset signal-to-noise ratio threshold. If the signal-to-noise ratio of the output signal of a certain stage is greater than or equal to the preset signal-to-noise ratio threshold, then perform noise reduction processing on the corresponding output signal of that stage; otherwise, do not perform noise reduction processing on the output signal.

[0055] S25: Obtain the real-time power gain of the output signals measured by each stage of the amplification circuit for every two adjacent times, and calculate the difference between the real-time power gains measured for every two adjacent times. Among them,

[0056] If the difference is within the preset difference range, then keep the driving power supply level applied to the corresponding stage of the amplification circuit unchanged; if the difference is not within the preset difference range, then adjust the amplitude of the driving power supply level applied to the corresponding stage of the amplification circuit until the difference is within the preset difference range.

[0057] Microwave signals inevitably have certain noise components. If these noise components and the useful signal components in the microwave signals are amplified by a microwave amplifier at the same time, the amplified noise components will seriously interfere with or cover the useful signals. By performing adaptive noise reduction processing on the output signals of each stage of the amplification circuit in the microwave amplifier, it is possible to avoid the noise components contained in the microwave signals being amplified during the amplification process of each stage of the amplification circuit, thereby affecting the effectiveness of the microwave signals. In addition, a microwave amplifier usually includes multiple stages of amplification circuits such as a first-stage amplification circuit, a second-stage amplification circuit, and a third-stage amplification circuit in sequence. Different stages of amplification circuits operate independently and amplify the input microwave signals. By analyzing the real-time power gain of the output signals corresponding to two adjacent times of each stage of the amplification circuit and determining the difference between the two real-time power gains, it is possible to effectively determine that the gain of each stage of the amplification circuit for the microwave signals remains stable and does not experience a large gain drift. When the difference is not within the preset difference range, the amplitude of the drive power supply level applied to the corresponding stage of the amplification circuit is adjusted. In this way, by changing the drive power supply voltage level, it is possible to ensure that each stage of the amplification circuit accurately performs power amplification on the microwave signals with a specific gain coefficient.

[0058] In a specific embodiment, step S3 includes:

[0059] S31: During the process of power amplification, temperature sensors distributed in different regions of the microwave amplifier respectively collect the real-time operating temperatures of the corresponding regions;

[0060] S33: Determine whether the real-time operating temperature collected by each temperature sensor exceeds a preset temperature threshold; if the real-time operating temperature values collected by more than half of all the temperature sensors exceed the preset temperature threshold, then the real-time operating temperature of the microwave amplifier is in a high state; if the real-time operating temperature values collected by less than half of all the temperature sensors exceed the preset temperature threshold, then the real-time operating temperature of the microwave amplifier is in a low state;

[0061] S35: When the real-time operating temperature of the microwave amplifier is in a high state, the radiator connected to the microwave amplifier adjusts its heat dissipation intensity until the real-time operating temperature of the microwave amplifier returns to the preset temperature state; when the real-time operating temperature of the microwave amplifier is in a low state, the radiator connected to the microwave amplifier dissipates heat normally.

[0062] In an example, the radiator is a semiconductor cooling radiator. In this case, the refrigeration intensity of the microwave amplifier is adjusted until the real-time operating temperature of the microwave amplifier is in the preset temperature state.

[0063] During the operation of a microwave amplifier, corresponding heat is generated. If the heat is not dissipated in time, it will seriously affect the normal operation of the microwave amplifier. By setting temperature sensors at different positions in the microwave amplifier, the operating temperature of the microwave amplifier can be determined in real time. Subsequently, based on the high and low distribution of the operating temperatures in different regions of the microwave amplifier, the cooling intensity of semiconductor cooling radiators such as semiconductor cooling sheets is indicated, so as to ensure that the operating heat of the microwave amplifier can be dissipated to the greatest extent, thereby improving the stability and reliability of the operation of the microwave amplifier.

[0064] The second embodiment of the present invention discloses a microwave amplifier control system, as Figure 2 shown, including a microwave signal acquisition and amplification processing module, a microwave signal noise reduction and gain adjustment module, and a microwave amplifier heat dissipation adjustment module. Among them,

[0065] The microwave signal acquisition and amplification processing module is used to receive microwave signals from a signal source, send the microwave signals into a microwave amplification link for power amplification, and feedback the power-amplified microwave signals back to the signal source;

[0066] The microwave signal noise reduction and gain adjustment module is used to collect the output signals of each stage of the amplification circuit included in the microwave amplifier during the power amplification process of the microwave signals, and perform noise reduction processing on each stage of the output signals; analyze the output signals, calculate the real-time power gain of each stage of the amplification circuit, and adjust the drive power supply level of each stage of the amplification circuit according to the real-time power gain of each stage of the amplification circuit;

[0067] The microwave amplifier heat dissipation adjustment module is used to collect the real-time operating temperatures of different regions of the microwave amplifier during the power amplification process of the microwave signals, and control the heat dissipation intensity of the radiator connected to the microwave amplifier until the operating temperature of the microwave amplifier returns to the preset temperature state.

[0068] In a specific embodiment, the microwave signal acquisition and processing module receives microwave signals from a signal source through a signal scanning and searching method, identifies the microwave base station address corresponding to the received microwave signals. If the microwave base station address exists in a preset microwave base station address whitelist, the microwave signals are retained; otherwise, the microwave signals are deleted;

[0069] Subsequently, the retained microwave signals are sent into a microwave amplification link for power amplification, and the power-amplified microwave signals are feedback back to the signal source.

[0070] In a specific embodiment, the microwave signal noise reduction and gain adjustment module identifies the noise components of the output signals at each stage, determines the signal-to-noise ratio of each output signal accordingly, and compares the signal-to-noise ratio of each stage output signal with a preset signal-to-noise ratio threshold; if the signal-to-noise ratio of the output signal is greater than or equal to the preset signal-to-noise ratio threshold, noise reduction processing is performed on the output signal of the corresponding stage; otherwise, no noise reduction processing is performed on the output signal.

[0071] The microwave signal noise reduction and gain adjustment module calculates the difference between the two measured real-time power gains of the output signals of the adjacent two measurements of each stage amplifier circuit; if the difference is within the preset difference range, the driving power supply level applied to the corresponding stage amplifier circuit is kept unchanged; if the difference is not within the preset difference range, the driving power supply level applied to the corresponding stage amplifier circuit is adjusted until the difference is within the preset difference range.

[0072] In a specific embodiment, the microwave amplifier heat dissipation adjustment module is used to obtain the real-time operating temperatures of the corresponding areas collected by a plurality of temperature sensors distributed in different areas of the microwave amplifier. For example, two temperature sensors are placed in each area.

[0073] The microwave amplifier heat dissipation adjustment module is used to determine whether the real-time operating temperature collected by each temperature sensor exceeds a preset temperature threshold; if the real-time operating temperature values collected by more than half of all the temperature sensors exceed the preset temperature threshold, the real-time operating temperature of the microwave amplifier is in a high state; if the real-time operating temperature values collected by less than half of all the temperature sensors exceed the preset temperature threshold, the real-time operating temperature of the microwave amplifier is in a low state.

[0074] When the real-time operating temperature of the microwave amplifier is in a high state, the heat sink connected to the microwave amplifier adjusts its heat dissipation intensity until the real-time operating temperature of the microwave amplifier returns to the preset temperature state; when the real-time operating temperature of the microwave amplifier is in a low state, the heat sink connected to the microwave amplifier dissipates heat normally.

[0075] It can be seen from the contents of the above embodiments that the microwave amplifier control method and system instruct the microwave amplifier to identify and distinguish the received microwave signals, thereby performing differentiated power amplification for the uplink microwave signals and the downlink microwave signals. Meanwhile, during the power amplification operation of the microwave amplifier, the working state of each level of the amplification circuit of the microwave amplifier is adjusted according to the noise component and power gain state of the output signal of each level of the amplification circuit of the microwave amplifier, and the heat dissipation intensity of the radiator can be controlled according to the real-time working temperature of the microwave amplifier, so that the working temperature of the microwave amplifier is restored to the preset temperature state. In this way, differentiated amplification processing can be performed for different types of microwave signals, and the heat generated by the microwave amplifier during operation can be effectively and timely actively dissipated, thereby improving the stability and reliability of the operation of the microwave amplifier.

[0076] Obviously, the above embodiments of the present invention are merely examples for clearly illustrating the present invention, and are not limitations on the implementation methods of the present invention. For ordinary technicians in the relevant field, other different forms of changes or modifications can be made based on the above description. It is impossible to list all the implementation methods here. All obvious changes or modifications derived from the technical solution of the present invention are still within the protection scope of the present invention.
