[0002] Radio frequencies are a scarce national strategic resource, and the state implements unified planning for their use. Currently, the nationally assigned radio frequencies for railway use are the 400MHz, 450MHz, 800MHz, and 900MHz bands. Following the latest requirements issued by the Ministry of Industry and Information Technology, adjustments to the planning of railway radio resources in these frequency bands have officially begun.

[0030] Example 1

[0031] Figure 1a This is a schematic diagram of the architecture of a frequency planning system provided by the first embodiment of the present invention. Figure 1a As shown, the frequency planning system at least includes a line layer management module 101, an information display module 102, a line / site selection module 103, a communication frequency allocation module 104, an interference analysis module 105 and a frequency expansion module 106.

[0032] The route layer management module 101 supports editing the route class of train routes, the route organization to which the train routes belong, the longitude and latitude information of stations along the train routes, and route information. Route classes can include inter-bureau trunk lines, intra-bureau trunk lines, branch lines, and local railways. Furthermore, the route layer management module 101 supports user-defined route filtering conditions and visualizes the filtered train routes in the information display module. Optionally, route filtering conditions include route organization and route class.

[0033] The information display module 102 can visualize the train line, and display the communication frequency allocation information of the train line and the signal coverage range of the stations in the train line on the line visualization page, that is, the line length of the train line, the line grade and the uplink and downlink communication frequencies allocated to the stations, as well as the stations with communication interference in the train line and the type of interference.

[0034] The line / station selection module 103 can select a train line to which communication frequencies need to be allocated, and select a station to which communication frequencies need to be expanded.

[0035] The communication frequency allocation module 104 can allocate communication frequencies for the train running line selected in the line / station selection module 103 ; the frequency expansion module 106 can expand the communication frequencies for the stations selected in the line / station selection module 103 .

[0036] The interference analysis module 105 can perform communication interference verification on the train operation lines after the communication frequencies are allocated and the stations after the communication frequencies are expanded.

[0037] Figure 1b A flowchart of a method for visually configuring train line communication frequencies is provided for the first embodiment of the present invention. This embodiment is applicable to the case of deploying communication frequencies at stations on a train's operating line and can be applied to a frequency planning system. The method can be executed by a visual configuration device for train line communication frequencies. The visual configuration device for train line communication frequencies can be implemented in the form of hardware and / or software and can be configured in various general-purpose computing devices. Figure 1b As shown, the method includes:

[0038] S110 : In response to a line selection instruction, determine a target line to which no communication frequency is allocated on a visual line interface of existing lines.

[0039] Among them, the visual line interface can be used to display the line information of existing lines and the configuration information of the communication frequency of existing lines, such as the line length of the train running line, the line grade, the uplink and downlink communication frequencies (communication frequency pairs) allocated to the stations, and the stations with communication interference in the train running line and their interference types.

[0040] In an embodiment of the present invention, in the visualization page displayed by the information display module 102, the user can issue a line selection instruction through the line / site selection module 103. The information display module 102 responds to the line selection instruction and determines a target line with no assigned communication frequency from the existing lines displayed in the visualization page.

[0041] S120. Based on the candidate allocation frequency groups and according to the positional relationship of the sites in the target line, allocate communication frequency pairs to the sites in the target line, and generate at least two frequency allocation strategies for the target line.

[0042] Among them, the candidate allocation frequency group can be a combination of communication frequencies used in the digital wireless dispatching communication system for trains. It should be noted that the candidate allocation frequency group is a frequency pair within the 400MHz frequency band used in the digital wireless dispatching communication system for trains. Optionally, the 400MHz frequency band can be divided into one frequency point every 12.5kHz, and the frequency points are numbered with the frequency point with a center frequency of 403.0000MHz as frequency point number 1, and the center frequencies of other frequency points are f=403.0000MHz+(n-1)*0.0125MHz. The minimum frequency point in the 400MHz frequency band allocated by the Ministry of Industry and Information Technology is 403.4875MHz, and the maximum frequency point is 423.4125MHz. The corresponding parameter n has a value range of: n=40~1634. It should be noted that the train digital wireless dispatching communication system can choose to use 6 groups of frequencies (each group of frequencies contains 3 pairs of duplex frequencies, each pair of duplex frequencies contains 2 frequency points, which can also be recorded as 1 frequency pair). For example, the candidate allocation frequency groups can be shown in Table 1.

[0043] Table 1

[0044]

[0045] S130. Based on the communication interference verification rules, perform interference verification on the target frequency allocation strategy, determine the target site with communication interference, and highlight the target site of the target line in the visual line interface; and simultaneously perform interference elimination processing on the target site.

[0046] The target frequency allocation strategy may be a frequency allocation strategy ultimately applied to the target line. The communication interference verification rules may include co-channel interference verification rules and third-order intermodulation interference verification rules.

[0047] In an optional implementation of an embodiment of the present invention, based on the communication interference verification rules, the target frequency allocation strategy is interference verified to determine the target site where communication interference exists, including: according to the communication interference verification rules, traversing the sites of the target line to which the target frequency allocation strategy is applied, determining whether there is a target site that has communication interference with the site of the existing line, and determining the corresponding communication interference type of the target site.

[0048] In an embodiment of the present invention, the interference analysis module can be used to perform communication interference analysis on the target line to which the communication frequency has been allocated and the site after expansion, determine the site with interference, and highlight the site with interference in the information display module, while also indicating the type of interference. Optionally, the display method for highlighting the site with interference in the information display module can be adaptively set according to those skilled in the art. It should be noted that the interference elimination process can be to adjust the signal coverage range of the site with communication interference until the communication interference disappears.

[0049] Optionally, the co-frequency interference verification rule can be to traverse each station in the target line based on the station longitude and latitude information, and determine whether the station in the target line has co-frequency interference with other stations in the allocated line within the preset signal range based on the station distance between the other stations in the allocated line within the preset signal range and the station signal coverage radius. For example, it can be determined whether the station distance between the station in the target line and other stations in the allocated line within the preset signal range is greater than a preset multiple of the signal range of the station with the larger signal range of the two. If so, there is no co-frequency interference between the two. Otherwise, it is further determined whether the communication frequencies allocated to the two are the same. If they are the same, it is determined that there is co-frequency interference between the two. It should be noted that the allocated line may refer to a train running line that has been allocated a communication frequency. Optionally, the preset signal range and the preset multiple can be adaptively set according to those skilled in the art.

[0050] Optionally, the third-order intermodulation interference verification rule can be whether the station in the target line has an intersection with the signal coverage range of stations in two or more allocated lines at the same time, and the signal coverage range of the station in the allocated line also has an intersection, then an intermodulation frequency point will appear in the signal coverage range of the station in the allocated line. If the communication frequency allocated to the station in the target line is an intermodulation frequency point, it is determined that the station in the target line has third-order intermodulation interference. For example, the schematic diagram of third-order intermodulation interference can be as follows Figure 1c As shown in the figure, if the communication frequencies assigned to stations A and B in the allocated line (existing line) are f1 and f2, and if the communication frequency assigned to station C in the target line (the applied line, i.e. the line to be allocated) is 2f1-f2 or 2f2-f1, then in the following example: Figure 1c Third-order intermodulation interference will exist in the interference area shown.

[0051] The technical solution of the embodiment of the present invention adopts a communication frequency that complies with the use standard of the train digital wireless dispatching communication system, visually configures the communication frequency of the train running line through a visual configuration method, verifies the interference of the frequency allocation strategy of the train running line in real time, and displays the stations with communication interference, thereby improving the efficiency of configuring the communication frequency of the train digital wireless dispatching communication system and improving the maintenance and management efficiency of the train digital wireless dispatching communication system to adapt to the updated specification requirements of the 400MHz frequency band in the railway system.

[0052] Example 2

[0053] Figure 2 This is a flowchart of a method for visually configuring train line communication frequencies provided in the second embodiment of the present invention. This embodiment further refines the above embodiment and provides specific steps for allocating communication frequency pairs to stations in the target line based on candidate allocation frequency groups and according to the positional relationship of stations in the target line, thereby generating at least two frequency allocation strategies for the target line. It should be noted that, for the parts not described in detail in the embodiments of the present invention, reference can be made to the relevant descriptions of other embodiments, which will not be repeated here. Figure 2 As shown, the method includes:

[0054] S210 : In response to a line selection instruction, determine a target line to which no communication frequency is allocated in a visual line interface of existing lines.

[0055] S220 . For the first two stations on the target route, select the first two communication frequency pairs from the candidate allocation frequency groups in order as the communication frequency pairs allocated to the first two stations on the target route.

[0056] S230. For the remaining sites in the target line except the first two sites, if the site to be allocated and the target allocated site meet the same frequency spacing rule, determine the communication frequency to be allocated of the site to be allocated, which is in the first allocation range of the candidate allocation frequency group; wherein, there is one allocated site between the target allocated site and the site to be allocated.

[0057] S240. If the site to be allocated and the target allocated site do not meet the co-frequency spacing rule, determine the communication frequency to be allocated of the site to be allocated, which is within the second allocation range of the candidate allocation frequency group; wherein the co-frequency spacing rule means that the site distance between the site to be allocated and the target allocated site is greater than or equal to a preset multiple of the signal coverage radius of the largest site among the two sites.

[0058] S250: Generate at least two frequency allocation strategies for the target route based on the communication frequency pairs allocated to the first two stations on the target route and the first allocation range or the second allocation range corresponding to the station to be allocated.

[0059] S260: Based on the communication interference verification rule, perform interference verification on the target frequency allocation strategy, determine the target site with communication interference, and highlight the target site of the target line in the visual line interface.

[0060] Among them, the first allocation range may include all communication frequency pairs in the candidate allocation frequency group except the communication frequency pairs of the allocated sites between the target allocated sites and the sites to be allocated; the second allocation range may include all communication frequency pairs in the candidate allocation frequency group except the communication frequency pairs of the target allocated sites and the communication frequency pairs of the allocated sites between the target allocated sites and the sites to be allocated.

[0061] In an embodiment of the present invention, when allocating communication frequency pairs (uplink communication frequency and downlink communication frequency) to sites in a target line, communication frequency pairs can be allocated to the first two sites in sequence according to the site order of the target line. Starting from the nth site (n≥3), the site distance between the two sites needs to be calculated with the n-2th site, and the available frequency pairs of the nth site are determined based on the site distance (if the interval distance does not meet the same frequency interval rule, the range of the available frequency pairs of the nth site is the first allocation range; if the interval distance meets the same frequency interval rule, the range of the available frequency pairs of the nth site is the second allocation range), until all sites in the target line are allocated, and at least two frequency allocation strategies for the target line are obtained. It should be noted that in an embodiment of the present invention, when allocating communication frequency pairs to sites in a target line, if there is no hub site in the target line, the communication frequency pairs allocated to the sites in the target line belong to one frequency group, that is, in the at least two frequency allocation strategies of the target line, the communication frequency pairs in each frequency allocation strategy belong to the same frequency group. Optionally, the hub site may refer to a preset number of common sites on the train lines, and the preset number may be adaptively set according to those skilled in the art.

[0062] Optionally, after generating at least two frequency allocation strategies for the target line, it also includes: traversing at least two frequency allocation strategies according to the allocation strategy screening rules, and screening out frequency allocation strategies that meet the allocation strategy screening rules; wherein the allocation strategy screening rules include specifying the communication frequency pairs of the sites in the target line; and specifying the communication frequency pairs allocated to the sites in the target line, and the frequency groups to which they belong in the candidate allocation frequency groups.

[0063] Specifically, the user can set allocation strategy screening rules in the communication frequency allocation module to screen at least two frequency allocation strategies generated for the target line. For example, the user can specify the communication frequency pair allocated to the site in the target line, and the frequency group to which it belongs in the candidate allocation frequency group (see Table 1); if the frequency group specified by the user is "1F", then in the filtered allocation plan, the frequency numbers allocated to the sites in the target line can only include "1F1", "1F2", and "1F3"; if the frequency group specified by the user is "2F", then in the filtered allocation plan, the frequency numbers allocated to the sites in the target line can only include "2F1", "2F2", and "2F3". Secondly, the user can also specify the communication frequency pairs allocated to the sites in the target line. For example, the user can specify that the frequency number of a certain site in the target line must be "1F1", then in the filtered frequency allocation strategy, the communication frequency pair number allocated to the site can only be "1F1".

[0064] Optionally, in an embodiment of the present invention, if the user specifies the frequency group to which the communication frequency assigned to the site in the target line belongs in the candidate allocation frequency group, in order to avoid co-frequency interference in the same frequency group, a frequency allocation strategy in which the communication frequencies assigned to two adjacent sites are at least two frequency points apart is preferentially selected.

[0065] Optionally, in an embodiment of the present invention, in the visualization page displayed by the information display module, the user can issue a site selection instruction through the line / site selection module, and the information display module determines the target expansion site (such as a busy hub site) with frequency expansion needs in the visualization page in response to the site selection instruction; the frequency expansion module can expand the communication frequency of the target expansion site. Specifically, the frequency expansion module can select the expanded communication frequency of the target expansion site from the candidate expansion frequency group while avoiding the principle of intra-group intermodulation. It should be noted that the candidate expansion frequency group and the candidate allocation frequency group can form a complete 400MHz frequency band applied to the train digital wireless dispatching communication system, and there is no intersection between the candidate expansion frequency group and the candidate allocation frequency group.

[0066] The technical solution of the embodiment of the present invention determines the first allocation range or the second allocation range of the communication frequency of the site to be allocated based on the site distance between the site to be allocated and the target allocated site, as well as the signal coverage radius of the site, thereby ensuring that there is no communication interference between the site to be allocated and the allocated site in the target line, and improving the accuracy of communication frequency configuration for the target line.
