Description

Technical Field

[0001] The present application relates to the technical field of data transmission, and in particular to a method, device and storage medium for image transmission and control based on dynamic EQ compensation and nuclear radiation resistance. Background Art

[0002] With the rapid development of information technology, video signal transmission plays a vital role in numerous fields, such as security surveillance, video conferencing, and distance education. Unshielded twisted pair (UTP), as a low-cost, easy-to-install, and easy-to-maintain transmission medium, is widely used in video signal transmission. However, in practical applications, UTP still faces some technical challenges in video signal transmission.

[0003] First of all, signal attenuation is a major problem faced when transmitting video signals over unshielded twisted pair cables. Due to the loss of the conductors and the medium itself, the video signal will gradually weaken during transmission. This attenuation will lead to a decline in signal quality, manifested as blurred images, loss of details, and in severe cases, it may even cause the signal to be unable to be correctly received and decoded. The degree of signal attenuation is affected by many factors, including transmission distance, signal frequency, and the quality of the cable itself. In order to address the problem of signal attenuation, the industry has developed some equalization compensation solutions. For example, the patent application with publication number CN103139526A and invention name "System and method for cable equalization" receives the video signal transmitted on the cable through an equalizer, provides compensation for the frequency attenuation that occurs during transmission on the cable, and outputs the compensated video signal. For example, the patent application with publication number CN101667412A and invention name "Signal compensation device, signal compensation method and multi-computer switching system" solves the problems of ghosting and overexcitation caused by distance in signal transmission by using a combination of a de-differentializing unit, a detection unit, a control unit, a filter and an equalizer in the signal compensation device, thereby achieving accurate compensation of the video signal and maintaining picture clarity.

[0004] It's important to note that nuclear radiation interference is also a significant factor affecting the quality of video signal transmission over unshielded twisted-pair cables. Common types of nuclear radiation include alpha, beta, gamma, neutrons, and X-rays. These radiations can couple onto unshielded twisted-pair cables, interfering with video signals and causing degradation, noise, distortion, and other issues. The intensity and type of nuclear radiation interference depend on environmental factors, making signal transmission quality uncertain and volatile. However, existing equalization and compensation solutions often fail to fully account for the impact of nuclear radiation interference and lack dynamic compensation mechanisms for this interference.

[0005] The existing equalization compensation scheme for unshielded twisted-pair video signal transmission lacks a dynamic compensation mechanism for nuclear radiation interference, and a corresponding technical solution is urgently needed. Summary of the Invention

[0010] According to another aspect of the embodiment of the present disclosure, there is also provided an image transmission and control device based on dynamic EQ compensation and nuclear radiation resistance, comprising: a processor; and a memory connected to the processor, for providing the processor with instructions for processing the following processing steps: collecting intensity values ​​of various types of nuclear radiation in the environment in which the unshielded twisted pair is located, and determining the first conductor loss coefficient and the first dielectric loss coefficient of the unshielded twisted pair based on the intensity values ​​of the various types of nuclear radiation; transmitting a target video signal to which a first test pulse signal is added through the unshielded twisted pair, and determining the second conductor loss coefficient and the second dielectric loss coefficient of the unshielded twisted pair according to the loss of the first test pulse signal in the target video signal after transmission. dielectric loss coefficient; fusing the first conductor loss coefficient with the second conductor loss coefficient to obtain a third conductor loss coefficient; fusing the first dielectric loss coefficient with the second dielectric loss coefficient to obtain a third dielectric loss coefficient; based on the signal frequency of the target video signal, the third conductor loss coefficient and the third dielectric loss coefficient, determining the cable attenuation coefficient of the unshielded twisted pair according to a preset composite attenuation model; and based on the cable attenuation coefficient, calculating the amplitude attenuation factor of the unshielded twisted pair according to a preset cable transmission function, and performing equalization compensation on the target video signal after transmission through the unshielded twisted pair based on the amplitude attenuation factor.

[0011] This application first collects the intensity values ​​of various types of nuclear radiation in the environment of an unshielded twisted pair cable and dynamically calculates the first conductor loss coefficient and first dielectric loss coefficient of the unshielded twisted pair cable based on the nuclear radiation intensity values. This is used to precisely quantify the impact of environmental nuclear radiation on the transmission performance of the unshielded twisted pair cable. Next, a target video signal with a first test pulse signal added is transmitted through the unshielded twisted pair cable. Based on the loss of the first test pulse signal in the transmitted target video signal, the second conductor loss coefficient and second dielectric loss coefficient of the unshielded twisted pair cable are determined to quantify the combined impact of signal frequency and all environmental factors on the transmission performance of the unshielded twisted pair cable. Secondly, the first loss coefficient (including the first conductor loss coefficient and the first dielectric loss coefficient), which precisely quantifies the impact of environmental nuclear radiation, is combined with the second loss coefficient (including the second conductor loss coefficient and the second dielectric loss coefficient), which comprehensively reflects the impact of environmental factors and signal frequency. This results in a composite loss coefficient (including the third conductor loss coefficient and the third dielectric loss coefficient) that can dynamically adapt to complex electromagnetic environments and is used for subsequent calculation of the cable attenuation coefficient. Secondly, based on the signal frequency of the target video signal, the third conductor loss coefficient, and the third dielectric loss coefficient, the cable attenuation coefficient of the unshielded twisted pair is calculated according to a preset composite attenuation model, which is used for subsequent calculation of the signal attenuation loss value. Finally, based on the cable attenuation coefficient, the amplitude attenuation factor of the unshielded twisted pair is calculated according to a preset cable transmission function. Based on this amplitude attenuation factor, the target video signal after transmission through the unshielded twisted pair is equalized and compensated to restore the original quality of the target video signal. This achieves the technical effects of dynamically adapting to complex nuclear radiation environments, dynamically and accurately compensating for signal attenuation, and significantly improving the quality and stability of unshielded twisted pair video signal transmission. This solves the technical problem that the existing equalization compensation scheme for unshielded twisted pair video signal transmission lacks a dynamic compensation mechanism for nuclear radiation interference.

[0022] In the above operating environment, according to the first aspect of this embodiment, a method for image transmission and control based on dynamic EQ compensation and nuclear radiation resistance is provided. Figure 2 A schematic diagram showing the process of the method is shown in FIG. Figure 2 As shown, the method includes: S202: collecting intensity values ​​of various types of nuclear radiation in an environment where the unshielded twisted pair is located, and determining a first conductor loss coefficient and a first dielectric loss coefficient of the unshielded twisted pair based on the intensity values ​​of the various types of nuclear radiation; S204: Transmitting the target video signal to which the first test pulse signal is added through the unshielded twisted pair cable, and determining a second conductor loss coefficient and a second dielectric loss coefficient of the unshielded twisted pair cable based on a loss condition of the first test pulse signal in the transmitted target video signal; S206: Merging the first conductor loss coefficient and the second conductor loss coefficient to obtain a third conductor loss coefficient; and merging the first dielectric loss coefficient and the second dielectric loss coefficient to obtain a third dielectric loss coefficient.

[0023] Specifically, nuclear radiation intensity sensors can be pre-placed around unshielded twisted-pair cables to ensure comprehensive coverage and accurate capture of all types of nuclear radiation affecting the cables. When video signals need to be transmitted via unshielded twisted-pair cables, sensors can be used to monitor the transmission environment in real time to obtain information on the intensity of various types of nuclear radiation present in the environment. Subsequently, based on this collected nuclear radiation intensity data, a series of calculations and analyses are performed to determine the conductor and dielectric loss characteristics of the unshielded twisted-pair cables under the influence of nuclear radiation. This yields a first conductor loss coefficient and a first dielectric loss coefficient that can precisely quantify the loss of the unshielded twisted-pair cables in a specific nuclear radiation environment, providing basic data for subsequent steps.

[0024] The first test pulse signal is then superimposed on the target video signal. After transmission through the unshielded twisted pair cable, the amplitude attenuation of each frequency component in the first test pulse signal is analyzed at the receiving end using a Fourier transform. By analyzing the amplitude attenuation of each frequency component, the second conductor loss coefficient and second dielectric loss coefficient of the unshielded twisted pair cable in actual transmission scenarios can be calculated. This quantifies the combined impact of signal frequency and all environmental factors on the transmission performance of the unshielded twisted pair cable, providing dynamic data support for cable performance evaluation.

[0025] Next, considering the frequency characteristics of the target video signal to be transmitted, combined with the loss coefficient obtained through fusion processing, the cable attenuation coefficient of the unshielded twisted pair is determined through a preset composite attenuation model to establish a direct connection between signal frequency and line loss, providing a key parameter for quantifying the attenuation degree of the video signal during transmission. The expression of the composite attenuation model is:

[0026] Where, is the cable attenuation coefficient of the unshielded twisted pair, k1 is the third conductor loss coefficient of the unshielded twisted pair, k2 is the third dielectric loss coefficient of the unshielded twisted pair, and f is the signal frequency of the target video signal to be transmitted.

[0027] Finally, based on the determined cable attenuation coefficient, the amplitude attenuation factor of the unshielded twisted pair cable is calculated using the existing cable transfer function. Subsequently, equalization compensation is performed on the target video signal after transmission over the unshielded twisted pair cable at the receiving end. This compensation mechanism eliminates signal attenuation during transmission, ensuring that the video signal is restored to near-original quality at the receiving end, achieving clear and stable video signal transmission. The cable transfer function is:

[0028] Where, Amplitude attenuation factor of unshielded twisted pair, is the cable attenuation coefficient of the unshielded twisted pair cable, and L is the length of the unshielded twisted pair cable.

[0029] As mentioned in the background, nuclear radiation interference is also a significant factor affecting the quality of video signal transmission over unshielded twisted-pair cables. Common types of nuclear radiation include alpha, beta, gamma, neutrons, and X-rays. These radiations can couple onto unshielded twisted-pair cables, interfering with video signals and causing degradation of signal quality, noise, distortion, and other issues. The intensity and type of nuclear radiation interference depend on environmental factors, making signal transmission quality uncertain and volatile. However, existing equalization and compensation schemes often fail to fully account for the impact of nuclear radiation interference and lack dynamic compensation mechanisms for this interference.

[0030] In light of this, this application first collects the intensity values ​​of various types of nuclear radiation in the environment of an unshielded twisted pair cable and dynamically calculates the first conductor loss coefficient and first dielectric loss coefficient of the unshielded twisted pair cable based on the nuclear radiation intensity values. This is used to precisely quantify the impact of environmental nuclear radiation on the transmission performance of the unshielded twisted pair cable. Next, a target video signal with a first test pulse signal added is transmitted through the unshielded twisted pair cable. Based on the loss of the first test pulse signal in the transmitted target video signal, the second conductor loss coefficient and second dielectric loss coefficient of the unshielded twisted pair cable are determined to quantify the combined impact of signal frequency and all environmental factors on the transmission performance of the unshielded twisted pair cable. Secondly, the first loss coefficient (including the first conductor loss coefficient and the first dielectric loss coefficient), which precisely quantifies the impact of environmental nuclear radiation, is combined with the second loss coefficient (including the second conductor loss coefficient and the second dielectric loss coefficient), which comprehensively reflects the influence of environmental factors and signal frequency. This results in a composite loss coefficient (including the third conductor loss coefficient and the third dielectric loss coefficient) that can dynamically adapt to complex electromagnetic environments and is used for subsequent calculation of the cable attenuation coefficient. Secondly, based on the signal frequency of the target video signal, the third conductor loss coefficient, and the third dielectric loss coefficient, the cable attenuation coefficient of the unshielded twisted pair is calculated according to a preset composite attenuation model, which is used for subsequent calculation of the signal attenuation loss value. Finally, based on the cable attenuation coefficient, the amplitude attenuation factor of the unshielded twisted pair is calculated according to a preset cable transmission function. Based on this amplitude attenuation factor, the target video signal after transmission through the unshielded twisted pair is equalized and compensated to restore the original quality of the target video signal. This achieves the technical effects of dynamically adapting to complex nuclear radiation environments, dynamically and accurately compensating for signal attenuation, and significantly improving the quality and stability of unshielded twisted pair video signal transmission. This solves the technical problem that the existing equalization compensation scheme for unshielded twisted pair video signal transmission lacks a dynamic compensation mechanism for nuclear radiation interference.

[0031] Optionally, the operation of determining the first conductor loss coefficient and the first dielectric loss coefficient of the unshielded twisted pair based on the intensity values ​​of various types of nuclear radiation includes: calculating the first conductor loss coefficient of the unshielded twisted pair based on the intensity values ​​of various types of nuclear radiation using a first formula; wherein the first formula is:

[0032] Among them, k 11 is the first conductor loss coefficient of the unshielded twisted pair; x0 is the initial conductor loss coefficient of the unshielded twisted pair in a non-nuclear radiation environment; I i is the intensity value of the i-th type of nuclear radiation; x i is a constant term of the intensity value of the i-th type of nuclear radiation, and the constant term is a preset value; n is the number of types of nuclear radiation in the environment where the unshielded twisted pair is located; Based on the intensity values ​​of various types of nuclear radiation, a first dielectric loss coefficient of the unshielded twisted pair is calculated using a second formula; wherein the second formula is:

[0033] Among them, k 21 is the first dielectric loss coefficient of the unshielded twisted pair; y0 is the initial dielectric loss coefficient of the unshielded twisted pair in a non-nuclear radiation environment; I i is the intensity value of the i-th type of nuclear radiation; y i is a constant term of the intensity value of the i-th type of nuclear radiation, and the constant term is a preset value; n is the number of types of nuclear radiation in the environment where the unshielded twisted pair is located.

[0034] Specifically, in practical applications, unshielded twisted-pair cables are often exposed to complex nuclear radiation environments. Considering the impact of these radiation sources can more accurately assess the transmission performance of unshielded twisted-pair cables in actual use. Therefore, after collecting the radiation intensity value, a preset mathematical model (including the first and second formulas described above) is used to convert the radiation intensity value into the conductor loss coefficient and dielectric loss coefficient of the unshielded twisted-pair cable. By incorporating the radiation intensity value and related constant terms, this preset mathematical model can more accurately calculate the first conductor loss coefficient and first dielectric loss coefficient of the unshielded twisted-pair cable in a specific nuclear radiation environment.

[0035] The first conductor loss factor k 11 It represents the conductor loss coefficient of unshielded twisted pair cables in a specific nuclear radiation environment. It is a comprehensive indicator that reflects the signal attenuation caused by various factors (including nuclear radiation) when transmitting signals in unshielded twisted pair cables. Therefore, in the first formula, the initial conductor loss coefficient x0 of unshielded twisted pair cables in a nuclear radiation-free environment is used as the reference value. This is the inherent conductor loss of unshielded twisted pair cables in an ideal environment without any nuclear radiation interference. In the first formula, the different effects of different types of nuclear radiation on unshielded twisted pair cables are also considered, and a specific constant term x is set for each type of nuclear radiation. i .

[0036] k 21 represents the dielectric loss coefficient of the unshielded twisted pair in a specific nuclear radiation environment. In the second formula, the initial dielectric loss coefficient y0 of the unshielded twisted pair in a non-nuclear radiation environment is used as the reference value. This reference value is the inherent dielectric loss of the unshielded twisted pair in an ideal environment without any nuclear radiation interference. In the second formula, the different effects of different types of nuclear radiation on the unshielded twisted pair are also considered, and a specific constant term y is set for each type of nuclear radiation. i .

[0037] Therefore, by introducing the nuclear radiation intensity value and related constant terms, the conductor loss and dielectric loss of unshielded twisted pair cables in a specific nuclear radiation environment can be calculated more accurately, which helps to formulate a more reasonable signal transmission compensation strategy and improve the reliability and stability of signal transmission.

[0038] Optionally, the constants in the first formula and the second formula are determined by the following steps: in a non-nuclear radiation test environment, transmitting a second test pulse signal of different frequencies through the unshielded twisted pair, and performing a loss analysis on the second test pulse signal after transmission, and determining the initial conductor loss coefficient and the initial dielectric loss coefficient of the unshielded twisted pair according to the results of the loss analysis; in a nuclear radiation test environment, transmitting a second test pulse signal of different frequencies through the unshielded twisted pair, and performing a loss analysis on the second test pulse signal after transmission, and determining multiple groups of loss coefficients of the unshielded twisted pair according to the results of the loss analysis; wherein each group of loss coefficients includes a test conductor loss coefficient and a test dielectric loss coefficient; collecting the test intensity values ​​of various types of nuclear radiation in the nuclear radiation test environment, setting the constants in the first formula and the second formula as unknown quantities, substituting the test intensity values ​​of various types of nuclear radiation, the multiple groups of loss coefficients, the initial conductor loss coefficient and the initial dielectric loss coefficient into the first formula and the second formula, and solving the constants in the first formula and the second formula.

[0039] Specifically, in a non-nuclear radiation test environment (e.g., in a shielded room), second test pulse signals (f1, f2, ..., fn) of different frequencies are transmitted through an unshielded twisted pair cable. The ends of the unshielded twisted pair cable (length L) are connected to Port 1 and Port 2 of a vector network analyzer (VNA). The vector network analyzer sends a frequency sweep signal (e.g., 1 MHz step) and records the frequency at each frequency point f i Insertion loss S 21 (f i ). Then, calculate each frequency point f by the following formula i Cable attenuation coefficient of unshielded twisted pair cable :

[0040] Next, each frequency point f i Cable attenuation coefficient of unshielded twisted pair cable Substituting the composite attenuation model, we obtain the overdetermined equations:

[0041] The above overdetermined equations are solved using the least squares method to ultimately obtain k1 and k2 under a non-nuclear radiation test environment. Thus, k1 under a non-nuclear radiation test environment is determined as the initial conductor loss coefficient x0 of the unshielded twisted pair cable, and k2 under a non-nuclear radiation test environment is determined as the initial dielectric loss coefficient y0 of the unshielded twisted pair cable.

[0042] Through the above steps, the initial conductor loss coefficient x0 and the initial dielectric loss coefficient y0 of the unshielded twisted pair cable in a non-nuclear radiation environment can be accurately measured.

[0043] Next, multiple types of nuclear radiation sources were introduced into the shielded room, and then the intensity value of each type of nuclear radiation source was accurately measured using a spectrum analyzer and an electromagnetic field probe. (Unit: dBμV / m) and record its frequency band characteristics. Then, send a second test pulse signal with multiple frequency groups (covering the target frequency band, such as 1MHz-150MHz), with each frequency group corresponding to a test point. For example, send pulse signals with frequencies of 10MHz, 50MHz, and 100MHz, and repeat the test three times at each frequency point to reduce random errors. Use a vector network analyzer (VNA) to measure the insertion loss (S 21 parameters), and each frequency point f i Cable attenuation coefficient of unshielded twisted pair cable After that, each frequency point f i Cable attenuation coefficient of unshielded twisted pair cable Substituting the composite attenuation model into the corresponding set of equations, we solved them using the least squares method to obtain k1 and k2 under the nuclear radiation test environment. Repeating the above method for multiple rounds of experiments yielded k1 and k2 under multiple sets of nuclear radiation test environments.

[0044] Assume that the constants in the first formula are unknown quantities, and take k1 in the nuclear radiation test environment as the first conductor loss coefficient k of the unshielded twisted pair cable. 11 , the initial conductor loss coefficient x0 and k1 under multiple groups of nuclear radiation test environments obtained above are respectively substituted into the first formula to obtain the corresponding overdetermined equations and solve them to obtain the specific values ​​of the constants in the first formula.

[0045] Similarly, set the constants in the second formula as unknown quantities, and treat k2 in the nuclear radiation test environment as the first dielectric loss coefficient k of the unshielded twisted pair cable. 21 , the initial dielectric loss coefficient y0 and k2 under multiple groups of nuclear radiation test environments obtained above are respectively substituted into the first formula to obtain the corresponding overdetermined equations and solve them to obtain the specific values ​​of the constants in the second formula.

[0046] In this way, the constants in the first and second formulas can be accurately determined.
