Description

Technical Field

[0001] The present invention belongs to the technical field of leaky coaxial cable design, and in particular relates to a segmented slot design method, system and storage medium for a leaky coaxial cable. Background Art

[0002] Leaky coaxial cables typically exhibit uniform transmission attenuation and coupling loss performance along their length. Their system loss exhibits a linear trend over long lengths, with the attenuation decreasing as the slope is proportional to the cable's system loss. This means that the reception level at the headend of the leaky coaxial cable is significantly better than at the end. However, in actual use, the signal level at the terminal device must meet a certain threshold to meet the communication link transmission requirements. In this case, a biased signal level at the headend of the leaky coaxial cable indicates that the cable itself attenuates excessive energy at the headend, significantly limiting its maximum usable length. The outer conductor of a leaky coaxial cable is a thin copper sheet with a continuously slotted structure. The slot pattern determines the cable's electromagnetic radiation capability. Currently used leaky coaxial cables feature a consistent outer conductor slot pattern along their length, resulting in consistent radiation capability and coupling loss values. Transmission attenuation is also consistent across the cable. The system loss curve for a leaky coaxial cable is a decreasing line with length, and the reception level at the terminal signal receiving device corresponds to the system loss value. However, for terminal devices, the receiving level only needs to meet the signal sensitivity required for communication. Excessively strong signal levels indicate that the leaky coaxial cable is radiating excessive electromagnetic energy. By suppressing radiation at the beginning of the leaky coaxial cable and enhancing it at the end, the overall system loss of the leaky coaxial cable can be improved. Alternatively, by increasing the length of the leaky coaxial cable, the coverage distance of base station equipment can be increased, thereby reducing project costs. Currently available low-loss leaky coaxial cable products reduce signal radiation at the beginning of the leaky coaxial cable by designing three to four different slot structures within the leaky coaxial cable, thereby improving overall system loss. However, due to product design and production difficulties, these leaky coaxial cables have only a few slot types at the beginning to suppress radiation. An ideal system loss curve should be a horizontal line with equal values at the beginning and end. This means that the beginning of the leaky coaxial cable is minimized, so that the beginning of the system loss curve is not significantly stronger than the end, while the end of the leaky coaxial cable radiates a stronger signal, so that the end of the system loss curve is not significantly weaker than the beginning. Current low-loss leaky coaxial cables generally add one or two slot structures at the headend to suppress the cable's radiation in sections, and one or two slot structures at the end to increase radiation, thereby optimizing the overall system loss of the leaky coaxial cable. This design, which includes three or four segments, still shows a significant difference in system loss between the headend and the end, typically around 10dB. Increasing the number of segments significantly increases the design and production complexity. Leaky coaxial cables designed for uniform system loss have different requirements for different lengths. Consequently, the slot configurations and segment combinations for different lengths of leaky coaxial cables are completely different.If the above method is adopted, a few types of slots are used to achieve the preferred optimization level. If the smoothness is to be achieved completely, the slot shapes will vary greatly. Summary of the Invention

[0035] Example 1 Additional aspects and advantages of embodiments of the present invention will be given in part in the following description and will become apparent from the following description or learned through practice of embodiments of the present invention. Figures 1-6 The embodiment of the present invention provides a segmented slot design method for a leaky coaxial cable, comprising: S1: Constructing a performance fitting formula for a leaky coaxial cable based on segmented slot state parameters, wherein the segmented slot state parameters include slot length Y, slot width W, and slot inclination angle α.

[0036] S2: Calculate the coupling loss of each slot segment structure on the leaky coaxial cable based on the performance fitting formula and the system loss threshold.

[0037] S3: Calculate the corresponding segmented slot state parameters and transmission attenuation according to the coupling loss of each segmented slot structure.

[0038] S4: Calculating expected size parameters of the leaky coaxial cable according to the segmented slot state parameters and transmission attenuation of each slot segment structure.

[0039] Leaky coaxial cables typically exhibit uniform transmission attenuation and coupling loss performance along their length. Their system loss can be represented by a system loss curve, which is a straight line with a decreasing slope relative to length. Ideally, the system loss curve should be a horizontal line with similar values at the beginning and end. This means that the beginning of the leaky coaxial cable minimizes radiation, making the beginning of the system loss curve not significantly stronger than the end, while the end of the leaky coaxial cable radiates a strong signal, making the end of the system loss curve not significantly weaker than the beginning. In reality, however, the system loss curve tends to be linear over length, with a decreasing slope relative to attenuation. This means that the wireless terminal receives significantly better power at the beginning of the leaky coaxial cable than at the end. In this case, the biased level at the beginning of the leaky coaxial cable indicates that the cable itself attenuates excessive energy at the beginning, significantly limiting the maximum usable length of the leaky coaxial cable. This paper proposes a step-by-step segmented slot design method. By creating a performance-fitting formula for leaky coaxial cable slot structures, the coupling loss and transmission attenuation of a series of segmented slots are calculated. This method then reversely derives the state parameters of a series of segmented slots of varying sizes, ultimately calculating the desired dimensional parameters for the leaky coaxial cable. By limiting the maximum and minimum system loss values to a desired threshold range, this design method achieves a uniform system loss curve for the novel leaky coaxial cable, ultimately achieving optimal system loss.

[0040] Specifically, step S1 constructs a performance fitting formula for the leaky coaxial cable according to the segmented slot state parameters, including: S11: Construct the radiation attenuation of the leaky coaxial cable based on the state parameters of the segmented slot: (1) S12: Construct the transmission attenuation and coupling loss of the leaky coaxial cable based on the radiation attenuation, where: The coupling loss is expressed as: (2)

[0041] The transmission attenuation is expressed as: (3) in, A composite function representing the state parameters of the segmented slot, A and B are fixed coefficients, and their specific values must be determined by the attenuation of at least two leaky coaxial cables with different coupling losses. and coupling loss The A and B values determined by the attenuation and coupling loss at different frequencies have certain deviations, so the average value can be used for processing. The transmission attenuation of the unslotted leaky coaxial cable is is the transmission attenuation of slotted leaky coaxial cable, is the radiation attenuation of the leaky coaxial cable, is the state parameter of the segmented slot, λ is the electromagnetic wavelength, r is the distance from the receiving antenna to the front of the leaky coaxial cable, is the coupling loss of the leaky coaxial cable.

[0042] In a specific embodiment of the present invention, a leaky coaxial cable is composed of an inner conductor, an insulation layer, a slotted outer conductor, and a jacket layer. The outer conductor radiates electromagnetic signals toward the exterior of the leaky coaxial cable through the slotted structure. Therefore, the structural characteristics of the leaky coaxial cable and the shape parameters of the slots determine the transmission attenuation and the intensity of the electromagnetic signals radiated outward from the leaky coaxial cable. The coupling loss lc at a distance of 2 meters from the front of the leaky coaxial cable is typically used to measure the intensity of electromagnetic signals radiated outward from the leaky coaxial cable, while the system loss L is used to measure the radiation intensity at various locations along the length of the entire leaky coaxial cable. The formula for the coupling loss lc can be expressed as: (4) Where A is a fixed coefficient, λ is the electromagnetic wavelength, and r is the distance from the receiving antenna to the front of the leaky coaxial cable. The coupling loss value at 2 meters is generally taken as the standard, that is, r = 2 meters. is the radiation attenuation of leaky coaxial cable.

[0043] Assume that the attenuation of the leaky coaxial cable corresponding to the unslotted outer conductor is , dB / 100m, the attenuation of slotted leaky coaxial cable is , dB / 100m, then . Traditional leaky coaxial cables are mainly designed with the same type of slots, such as Figure 4 As shown in Figure 1, even with segmented coupled low-loss leaky coaxial cable, there is still a large difference between the system loss curve at the beginning and end, generally around 10dB. The segmented slot state parameters include slot length Y, slot width W and slot tilt angle. ,but It can be expressed as slot length Y, slot width W and slot inclination angle In order to simplify the calculation, we can adjust only one of the three parameters, and keep the other two parameters unchanged. At this time, the radiation attenuation of the leaky coaxial cable is Expressed as: (5) in, Segmented slot state parameters, including slot length Y, slot width W and slot inclination angle .

[0044] The above formulas can be used to approximate the transmission attenuation of leaky coaxial cables as shown in formulas (2) and (3): And the calculation formula of coupling loss lc.

[0045] For example, assuming the slot width W and slot inclination angle The radiation attenuation of the leaky coaxial cable is Expressed as: .

[0046] For another example, assuming the slot length Y and slot inclination angle The radiation attenuation of the leaky coaxial cable is Expressed as: .

[0047] For another example, assuming that the slot length Y and slot width W remain unchanged, only the slot inclination angle is adjusted. , at this time the radiation attenuation of the leaky coaxial cable Expressed as: .

[0048] Specifically, step S2 calculates the coupling loss of each slot segment structure on the leaky coaxial cable according to the performance fitting formula and the system loss threshold, including: Assume that the head-end system loss of each slot segment structure is L (n-1)n , the terminal system loss is L n , the coupling loss is l cn , the system loss threshold is (X,X+C), by calculating the head-end system loss L of each slot segment structure (n-1)n , terminal system loss L n and coupling loss l cn , so that it satisfies L (n-1)n =X,L n = X+C, where The coupling loss of each slot segment structure is: l cn =X-(n-1)×C(6) Where n is the current sequence number of the leaky coaxial cable slot, C is a constant, X is the minimum system loss, and X+C is the maximum system loss.

[0049] In a specific embodiment of the present invention, according to relevant standards for leaky coaxial cable products, the system loss of the leaky coaxial cable at a certain frequency point does not exceed a preset threshold value. The system loss of the leaky coaxial cable at a certain frequency point is equal to the sum of the attenuation value of a length of the leaky coaxial cable and the coupling loss value at the frequency point. Assuming that the preset threshold value of the system loss at the frequency point is (X, X+C), the coupling loss of each slot segment structure on the leaky coaxial cable is l cn , the head-end system loss of each slot segment structure is L (n-1)n , the corresponding terminal system loss is L n , then the system loss L at the starting end of the leaky coaxial cable at 0 meters 01 is X (optimal value). Since the attenuation value at the first end is 0, the coupling loss here is l c1 =X, after passing through a section of leaky coaxial cable with an attenuation of C, the end system loss is L1=X+C. In order to keep the head end system loss of the second section of leaky coaxial cable at X, it is necessary to connect a section with a coupling loss of l c2 =XC slot structure, so that the system loss at the beginning of the next slot becomes L 12 = L1+(l c2 - l c1 ) = X, L2 = L 12 +C=X+C, so that the system loss of each point of the leaky coaxial cable from the first slot to the second slot remains between the value X and (X+C), and so on. The coupling loss of the leaky coaxial cable in each slot is l c Need to meet l cn =X-(n-1)×C, n is the current sequence number of the leaky coaxial cable slot n=1, 2, 3, 4..., such as Figure 5 and Figure 6 As shown, by limiting the maximum and minimum values of the system loss of the leaky coaxial cable to a smaller expected value, the system loss curve tends to a uniform and horizontal state, thereby ensuring that the system loss of the leaky coaxial cable reaches a better state.

[0050] Specifically, step S3 calculates the corresponding segmented slot state parameters and transmission attenuation according to the coupling loss of each slot segment structure, and determines the coupling loss of each leaky coaxial cable segment. Then, the state parameters of each slot segment structure are calculated according to formula (2), and the transmission attenuation a of each slot segment is calculated according to formula (3). n (Unit: dB / hundred meters).

[0051] For example, assuming the slot width W and slot inclination angle The slot length Y is adjusted, and the slot length Y can be calculated according to formula (2). Then, according to formula (3): Calculate the transmission attenuation of this slot section.

[0052] Specifically, step S4 calculates the expected size parameters of the leaky coaxial cable according to the segmented slot state parameters and transmission attenuation of each segmented slot structure, including: S41: Calculate the maximum total length of the leaky coaxial cable based on the segmented slot state parameters and transmission attenuation of each slot segment structure. The calculation formula is: (7) Where M is the maximum total length of the leaky coaxial cable that meets the expectation, is the state parameter of the nth segment slot, is the transmission attenuation of the nth slot segment structure, and C is a constant.

[0053] S42: Cutting an appropriate number of segments n according to actual needs to obtain desired size parameters of the leaky coaxial cable.

[0054] In a specific embodiment of the present invention, based on the segmented slot state parameters and transmission attenuation of each slot segment structure, the maximum total length of the leaky coaxial cable is calculated according to formula (7). Based on the actual required length, an appropriate number of segments, n, is selected. These n-segment slot structures are then input into the outer conductor slot processing equipment to sequentially form the combined slots. Intelligent laser cutting equipment can freely set different slot states for batch production, with up to hundreds of segmented types. Using intelligent laser cutting solutions instead of traditional punching methods enables continuous production of the slot structures designed in the present invention, ensuring that the maximum and minimum differences in the leaky coaxial cable system loss are within the expected requirements, thereby making the overall system loss curve tend to be uniform.

[0058] The expected size parameter calculation module 04 is used to calculate the expected size parameters of the leaky coaxial cable according to the segmented slot state parameters and transmission attenuation of each segmented slot structure.

[0059] This invention proposes a step-by-step segmented slot design system. First, the performance fitting formula for the leaky coaxial cable slot structure is created using the performance fitting formula creation module 01. The coupling loss calculation module 02 calculates the coupling loss of a series of segmented slots. The transmission attenuation calculation module 03 reversely derives the state parameters and transmission attenuation of a series of segmented slots of different sizes. Finally, the expected size parameter calculation module 04 calculates the expected size parameters of the leaky coaxial cable. By limiting the maximum and minimum system loss values within a desired threshold range, this design system achieves a uniform system loss curve for the novel leaky coaxial cable, thereby achieving optimal system loss.

[0063] In a specific embodiment of the present invention, the radiation attenuation of the leaky coaxial cable is first constructed by the radiation attenuation creation module 011. The transmission attenuation creation module 012 and the coupling loss creation module 013 then create the transmission attenuation and coupling loss of the leaky coaxial cable, respectively. By creating the transmission attenuation and coupling loss of the segmented slot, the state parameters of the segmented slot can be subsequently derived, making the system loss curve of the new leaky coaxial cable tend to be uniform.

Based on the actual required length, the segmentation module 042 selects an appropriate number of segments, n.
