[0054] Smart shipping is the forefront and trend of the current global shipping industry development. As a new shipping industry, smart shipping deeply integrates traditional shipping elements with modern information communication, artificial intelligence and other high-tech technologies. Smart shipping puts forward the most direct requirement for navigation security, namely the construction of a smart navigation support and security system.

[0055] In the process of building smart shipping, multiple base stations need to be set up so that ships can communicate within the communication coverage of the base stations. Therefore, it is necessary to determine the base station layout plan of the VHF data exchange system, wherein the base station layout plan includes the setting location information of multiple base stations.

[0056] In the related technology, the particle population is initialized by taking the elements of each row of the matrix as the coordinates of the base station to be solved in the target positioning space to obtain the original population; the reverse learning population is obtained based on the original population; the original population and the reverse learning population are respectively substituted into the fitness function to perform iterative calculation of the base station fitness, and the optimal positions of the individuals in the original population and the reverse learning population are obtained; and the determined optimal positions of the base stations are set as the base station layout plan of the very high frequency data exchange system.

[0057] However, there are some problems with the way of determining the base station layout plan. This method does not take into account the signal interference between base stations, resulting in poor communication performance of the very high frequency data exchange system, affecting the normal use of users.

[0058] In view of this, an embodiment of the present invention provides a method for determining a base station layout scheme for a very high frequency data exchange system, the method comprising: determining a communication uncovered blind area in the target area according to parameter information of a base station that has been constructed in the target area, the communication uncovered blind area being an area in the target area excluding the communication coverage range of the constructed base station; determining multiple base station construction sites in the target area, the base station construction sites being used to set up the base station, the electromagnetic environment noise of the base station construction sites being less than or equal to a first threshold, the electromagnetic radiation exposure value being less than or equal to a second threshold, and the altitude being greater than or equal to a third threshold; determining multiple alternative layout schemes based on the multiple base station construction sites, each alternative layout scheme comprising one or more base station construction sites, wherein, when a pre-constructed base station is set up, the communication coverage range of the pre-constructed base station of the one or more base station construction sites included in the base station layout scheme covers the communication uncovered blind area in the target area, and the antenna isolation between each pre-constructed base station in the base station layout scheme and any pre-constructed base station or the constructed base station is greater than a fourth threshold; determining the alternative layout scheme with the least number of base station construction sites among the multiple alternative layout schemes as the base station layout scheme for the very high frequency data exchange system.

The method can quickly and accurately determine the base station layout scheme of the very high frequency data exchange system, and avoid interference between base stations, thereby improving the communication performance of the very high frequency data exchange system, thereby improving the user experience.

[0060] In some embodiments, the base station layout scheme determination method of the VHF data exchange system provided in the embodiment of the present invention can be performed by a base station layout scheme determination system 100 of the VHF data exchange system (hereinafter referred to as the determination system 100). As an example, the determination system 100 can be any electronic device 200 with data processing capabilities, such as a general-purpose computer, a personal computer, a laptop computer, a switch or a tablet computer, etc. The specific implementation of the determination system 100 is not limited here.

[0061] Figure 1 The hardware structure diagram of the electronic device provided by the embodiment of the present invention is shown. The electronic device 200 includes a processor 210, a memory 220 and a communication interface 230.

[0062] The processor 210 may include one or more processing cores. The processor 210 uses various interfaces and lines to connect various parts in the electronic device 200, and executes various functions and processes data of the electronic device 200 by running or executing instructions, programs, code sets or instruction sets stored in the memory 220, and calling data stored in the memory 220. Optionally, the processor 210 can be implemented in at least one hardware form of a central processing unit (CPU), a graphics processing unit (GPU), a digital signal processing (DSP), a field-programmable gate array (FPGA), and a programmable logic array (PLA).

[0063] The memory 220 may include a random access memory (RAM) or a read-only memory (ROM). Optionally, the memory 220 includes a non-transitory computer-readable storage medium. The memory 220 may be used to store instructions, programs, codes, code sets, or instruction sets. The memory 220 may include a program storage area. The program storage area may store instructions for implementing an operating system, instructions for implementing at least one function (such as a blind spot determination function, solution determination, etc.), instructions for implementing the above-mentioned various method embodiments, etc.

Alternatively, at least two of the components can be set in the same device, that is, as different components in one device, similar to the deployment mode of devices or components in a distributed system.

[0066] It is to be understood that the structure illustrated in this embodiment does not constitute a specific limitation on the electronic device 200. In other embodiments of the present invention, the electronic device 200 may include more or fewer components than those illustrated, or combine certain components, or separate certain components, or arrange the components differently. The illustrated components may be implemented in hardware, software, or a combination of software and hardware.

[0067] The following describes a method for determining a base station layout scheme of a very high frequency data exchange system provided by an embodiment of the present invention in conjunction with the accompanying drawings.

[0068] Figure 2 The present invention provides a flowchart of a method for determining a base station layout scheme of a very high frequency data exchange system. Optionally, the method can be performed by a Figure 1 The method is executed by the electronic device 200 of the hardware structure shown, that is, by the determination system 100. The method may include the following steps:

[0069] S1. Determine a communication uncovered blind area in the target area according to parameter information of a base station that has been built in the target area. The communication uncovered blind area is an area in the target area excluding a communication coverage range of the base station that has been built.

[0070] Specifically, the parameter information includes multiple parameter values ​​for characterizing performance indicators and loss indicators of VHF communication stations. For example, the parameter information includes the transmission frequency of the constructed base station, the transmission power of the shore-based base station, the signaling antenna gain of the shore-based base station, the radio frequency feeder loss of the shore-based base station, etc.

[0071] In some embodiments, see Figure 3 , the above S1 specifically includes the following steps:

[0072] S11. Determine the communication coverage of the constructed base stations according to the parameter information of the constructed base stations in the target area.

[0073] For example, see Figure 4 , Figure 4A schematic diagram of a target area provided by an embodiment of the present invention includes an existing base station A and an existing base station B. The communication coverage range of the existing base station A is range a, and the communication coverage range of the existing base station B is range b.

[0074] In a possible implementation, the above S11 specifically includes the following steps:

[0075] The electric field strength value of the surrounding area of ​​each built base station is determined according to the parameter information of the built base stations in the target area. The area where the electric field strength value of each built base station is greater than or equal to the preset electric field strength value is determined as the communication coverage range of each built base station.

[0076] Specifically, the preset electric field strength value is determined based on the sensitivity corresponding to different channels of different services of the base station.

[0077] For example, see Table 1, which shows the sensitivities corresponding to different channels of different services of a base station.

[0078] Table 1

[0079]

[0080] Among them, AIS (Automatic Identification System) is the ship automatic identification system, ASM (Automated Manifest System) is the ship automatic management system, and VDES (VHF Data Exchange System) is the very high frequency data exchange system.

[0081] With reference to Table 1, when the service of the base station is AIS and the channels are AIS1 and AIS2, the preset electric field strength value is -107dBm.

[0082] Among them, the formula for determining the electric field strength value is:

[0083] E b =135.1+20lg f-ΔW+GLL h -L b .

[0084] Among them, E b is the electric field strength value, f is the transmission frequency, unit: MHz. ΔW is the difference between the base station transmission power and the standard 1kW. G is the base station transmitting antenna gain. L is the base station RF feeder loss, unit: dB. L h Insert loss for base station transmitter combiner. b is the transmission loss.

[0085] The formula for determining ΔW is:

[0086]

[0087] P t is the base station transmitter output power (unit: kW).

[0088] The formula for determining L is:

[0089] L = β × l.

[0090] β is the loss per unit length of the base station RF feeder line, and l is the unit length of the base station RF feeder line.

[0091] When the distance between the ship platform and the base station is d≤20km, the transmission loss L b The formula for determining is:

[0092] L b =69.55+26.16lg f-13.82*lg h b +[44.9-6.55lg h b ]*lg da(h m )

[0093] Where, f is the signal frequency, in MHz, and ranges from 150 to 1500 MHz. m h is the height of the ship platform antenna, in meters, with a value range of 1 to 10 meters. b The base station antenna altitude, in meters, ranges from 30 to 1000 meters.

[0094] α(h m ) is the correction factor for the antenna height at the receiving point, and the calculation formula is:

[0095] α(h m )=(1.1lg f-0.7)h m -(1.56lg f-0.8).

[0096] When the distance between the ship platform and the base station is 100km>d>20km, the transmission loss L b The formula for determining is:

[0097] L b =69.55+26.16lg f-13.82*lg h b +[44.9-6.55lg h b ]*(lg d) α -a(h m ).

[0098] α=1+(0.14+1.87·10 -4 f+1.07·10 -3 hb )×(lg d / 20) 0.8 .

[0099] It should be understood that the above determination methods of the electric field strength value and the transmission loss are merely exemplary, and the embodiments of the present invention do not impose any particular limitation on the determination methods of the electric field strength value and the transmission loss.

[0100] S12: Determine an area in the target area that does not include the communication coverage of the constructed base station as a communication uncovered blind area in the target area.

[0101] Exemplary, combined Figure 4 , see Figure 5 , the target area includes the constructed base station A and the constructed base station B. The communication coverage range of the constructed base station A is range a, and the communication coverage range of the constructed base station B is range b. The shaded area in the target area except range a and range b is the communication uncovered blind area in the target area.

[0117] For example, see Figure 7 , combined with the above example, Figure 7 The communication coverage of Point A, Point B and Point C when pre-built base stations are set for Point A, Point B and Point C. The communication coverage of Scheme 1 (Point A), Scheme 2 (Point B), Scheme 3 (Point C), Scheme 5 (Point A, Point C) and Scheme 6 (Point B, Point C) do not cover the communication coverage blind area, so Scheme 1 (Point A), Scheme 2 (Point B), Scheme 3 (Point C), Scheme 5 (Point A, Point C) and Scheme 6 (Point B, Point C) are deleted, and N alternative layout schemes are obtained, namely Scheme 4 (Point A, Point B) and Scheme 7 (Point A, Point B, Point C).

SL(θ) Rx It is the sidelobe level of the receiving antenna of any pre-built base station or built base station in the angular direction of the center line between the transmitting antenna of the pre-built base station and the receiving antenna of any pre-built base station or built base station, in dB.

[0135] S83. Determine multiple alternative layout schemes corresponding to the target base station construction site among the Z base station construction sites.

[0136] Among them, each of the multiple alternative layout schemes corresponding to the target base station construction site includes the target base station construction site, and when a pre-construction base station is set up, the communication coverage range of the pre-constructed base station covers the communication uncovered blind spot in the target area; and the antenna isolation between each pre-constructed base station in each alternative layout scheme and the pre-constructed base station corresponding to the base station construction site included in any alternative layout scheme is greater than a fourth threshold.

[0137] It should be understood that the target base station construction site is any one of the Z base station construction sites, that is, it is necessary to determine multiple alternative layout schemes corresponding to each of the Z base station construction sites.

[0138] Exemplarily, the target base station construction site is taken as point A for exemplary description below, and multiple alternative layout schemes corresponding to the base station construction site A are determined, wherein each of the multiple alternative layout schemes corresponding to point A includes point A, and when the communication coverage range of points A and C can completely cover the communication uncovered blind spots, and the antenna interference degree of the pre-built base station between any two points among points A, B and C is greater than the fourth threshold, the multiple alternative layout schemes corresponding to point A are determined to be AC ​​and ABC.

[0139] It should be understood that the method for determining the multiple alternative layout solutions corresponding to point B and point C is the same as that for point A, and will not be repeated here.

[0140] For ease of understanding, the following uses an example to illustrate the process of determining multiple alternative layout solutions corresponding to the target base station construction sites among the Z base station construction sites.

[0141] According to the communication uncovered blind area A, a base station construction point set P and a base station layout plan set C are established, wherein the base station construction point set P includes multiple base station construction points, and the base station layout plan set C is an empty set; when there are base station construction points that have not been considered in the candidate site set P, a base station construction point p is selected. i , determine the base station construction point p i Communication coverage i Remove the communication coverage area s in the communication coverage blind area A i The coverage area is obtained by calculating the communication coverage area A'. i If there is no overlap, the candidate site p i The blind area A cannot be covered, and the next base station construction point in the base station construction point set P is determined.

[0142] In the communication coverage blind area A is completely covered by the range s i In case of coverage, then p i In order to meet the required site selection plan, p i Included in the proposed site set Φ, that is:

[0143] C=C∪{p i};

[0144] If the communication does not cover the blind area A and the coverage range s i There is overlap, and A is not completely covered by s i Coverage, then remove p from the base station construction point set P i and all with p i The antenna interference degree of the pre-built base station between the base stations is greater than the fourth threshold of the base station construction point, that is,

[0145]

[0146] Among them, P' is if we consider the site p i When constructing a base station, a set of selected sites can also be considered. If the set P' is already an empty set, the returned alternatives are set to an empty set.

[0147] When the set P' is not an empty set, the communication uncovered blind area A' and the set P' are sent to the next level recursive algorithm. The returned site selection solution set C' is obtained from the next level recursive algorithm. The solution set C' means the solution that uses the sites in P' to cover the blind area A'. If the set C' is still an empty set, it means that there is no base station in P' that can cover all C' without causing interference. If the returned site selection solution set C' is not an empty set, the solution with the least number of sites will be selected from solution C' (there may be multiple solutions with the least number of sites), and the site p will be added to each solution. i , and stored in set C, that is:

[0148]

[0149] Here, ||·|| is the cardinality symbol of the set, i.e., the number of base stations included in the scheme.

[0150] If there is no base station construction point that has not been considered in the candidate site set P, then multiple candidate layout plans in the site selection plan set C are returned to obtain the target base station construction point p i Corresponding multiple alternative layout solutions.

[0151] S84. Determine the alternative layout scheme with the least number of base station construction sites among the multiple alternative layout schemes corresponding to each target base station construction site as the optimal alternative layout scheme corresponding to each target base station construction site, and obtain Z alternative layout schemes.

[0152] S4. Determine the alternative layout scheme with the least number of base station construction sites among the multiple alternative layout schemes as the base station layout scheme for the very high frequency data exchange system.

[0153] In some embodiments, the above S4 specifically includes the following steps: determining the number of base station construction sites of each of the Z alternative layout schemes, and determining the alternative layout scheme with the least number of base station construction sites as the base station layout scheme of the VHF data exchange system.

[0154] Exemplarily, in combination with the above examples, the number of base station construction sites of Scheme 4 is determined to be 2, and the number of base station construction sites of Scheme 7 is determined to be 3. Since Scheme 4 has the least base station construction sites, Scheme 4 is determined as the base station layout plan for the very high frequency data exchange system.

[0155] It can be seen from the above S1-S4 that the method provided by the embodiment of the present invention determines multiple alternative layout schemes based on multiple base station construction points, and then determines, based on multiple dimensional indicators, from multiple alternative layout schemes an alternative layout scheme that can completely cover communication uncovered blind areas, has no interference between base stations, and has the least base station construction points.
