Description

Technical Field

[0001] The present invention relates to the field of transmission technology, and in particular to a satellite baseband technology fusion networking system and a roaming switching method. Background Art

[0002] The existing satellite communication system is a system where multiple satellite beams use independent networks. Each satellite beam uses a network. The networks used by different satellite beams are independent of each other, and the network used by each satellite beam must use the corresponding Internet interaction address (IP address). If the Internet interaction address of the network used by a satellite beam changes, the network will be unusable.

[0003] At the same time, different satellites have different beam coverage areas. The communication of a satellite can only be used by long-distance transportation tools such as ships within its coverage area. If a transportation tool moves from the coverage area of ​​one satellite beam to the coverage area of ​​another satellite beam, satellite beam switching is required.

[0004] However, the process of satellite beam switching is a process of manually adjusting the angle or position of the satellite antenna, coupled with the modification of the Internet interaction address, which makes the operation process too cumbersome, thereby reducing navigation efficiency. Summary of the invention

[0005] The technical problem to be solved by the present invention is how to realize the automation of satellite beam switching and normal network access during long-distance transportation of transportation vehicles to improve shipping efficiency. In order to overcome the defects of the above-mentioned prior art, the present invention provides a fusion networking system of satellite baseband technology and a roaming switching method, including a fusion networking system of satellite baseband technology and a fusion networking roaming switching method of satellite baseband technology.

[0006] The present invention provides a satellite baseband technology integrated networking system, the system includes a positioning module, and further includes:

[0007] A modem module is configured to receive the position information obtained by the positioning module and issue an adjustment instruction when the transportation vehicle moves from the coverage area of ​​one satellite beam to the coverage area of ​​another satellite beam;

[0008] A control module, configured to adjust the position and / or angle of the satellite antenna according to the content of the adjustment instruction so that the satellite antenna locks the target satellite;

[0009] The network control module is configured to perform a next hop from the internet interaction address of the current communication network of the transportation means to the network of the other satellite beam according to the routing information protocol after receiving the adjustment instruction, and to send network access information after successful network access, and send network failure information when network access is not successful;

[0010] in,

[0011] The modulation and demodulation module is electrically connected to the positioning module and the control module respectively, and the network control module is electrically connected to the modulation and demodulation module.

[0012] The satellite baseband technology fusion networking system disclosed in the present invention, on the basis of the original positioning module, by setting a modulation and demodulation module and a control module, can use the modulation and demodulation module to receive the position information obtained by the positioning module, and issue an adjustment instruction when beam switching is required, and then use the control module to adjust the position and / or angle of the satellite antenna according to the content of the adjustment instruction so that the satellite antenna locks the target satellite, thereby overcoming the technical defect of the prior art that the angle or position of the satellite antenna needs to be manually adjusted. At the same time, by further setting a network control module to perform the next jump of the Internet interaction address of the current communication network of the transportation tool to the network of the target satellite beam according to the routing information protocol after receiving the adjustment instruction, the technical defect of frequently replacing the Internet interaction address is overcome. Therefore, in comparison, the system of the present invention can greatly improve the navigation efficiency, can be applied to the transportation of fishing boats and cruise ships, meet the most complex mobile application requirements, and provide a reliable broadband access platform for crew members and passengers around the world.

[0013] In a possible implementation manner, the modulation and demodulation module is configured to issue the adjustment instruction according to the following steps:

[0014] A1: receiving the current position information of the transport tool obtained by the positioning module to determine the current position of the transport tool;

[0015] A2: judging whether the transportation means satisfies the condition of traveling from the coverage area of ​​one satellite beam to the coverage area of ​​another satellite beam based on the comparison result of the stored beam description information of the satellite beams involved in the transportation route and the current position of the transportation means;

[0016] If yes, proceed to the next step;

[0017] If not, then go back to step A1;

[0018] A3: Determine how many satellite beams cover the coverage area of ​​another satellite beam reached by the transportation vehicle;

[0019] If the area is covered by only one satellite beam, the satellite beam is used as the target satellite beam and the adjustment instruction to switch to the satellite beam is issued, and then the step A1 is executed again;

[0020] If the area is covered by more than one satellite beam, the satellite beam with the highest priority is used as the target satellite beam according to the stored beam priority order, and then the next step is executed;

[0021] A4: issuing the adjustment instruction to switch to the target satellite beam;

[0022] A5: Determine whether the network control module sends out the information of not accessing the network. If so, select the next satellite beam as the target satellite beam according to the stored beam priority order, and then return to execute the step A4;

[0023] If not, then go back to step A1;

[0024] This solution can ensure the orderly and efficient switching of satellite antennas on transportation vehicles according to the distribution of satellite beam coverage areas, thereby ensuring orderly access to the network.

[0025] In one possible implementation, the beam description information includes satellite longitude, satellite downlink frequency, satellite symbol rate, satellite receive polarization, satellite transmit polarization, satellite receive local oscillator, satellite transmit local oscillator and satellite beam map; thereby ensuring accurate acquisition of geometric information of the satellite beam coverage area, which is beneficial for confirming whether the transportation vehicle needs to switch satellite beams for communication.

[0026] In a possible implementation manner, in step A2, the condition for moving from the coverage area of ​​one satellite beam to the coverage area of ​​another satellite beam is:

[0027] The current position of the vehicle is within the coverage area of ​​another satellite beam.

[0028] In a possible implementation, the adjustment instruction includes beam description information of the target satellite beam; this helps the control module to accurately calculate the adjustment position and angle of the satellite antenna, thereby ensuring that the satellite antenna locks onto the satellite.

[0029] In a possible implementation, the control module includes:

[0030] a calculation unit, configured to calculate the position and / or angle of the satellite antenna according to the beam description information of the target satellite beam, and form a driving instruction;

[0031] An actuator, which adjusts the position and / or angle of the satellite antenna according to the driving instruction to lock the target satellite;

[0032] in,

[0033] The computing unit is electrically connected to the modulation and demodulation module, and the execution element is electrically connected to the computing unit.

[0034] In a possible implementation, the network control module includes outbound routers, inbound routers and hubs, and a network controller, the number of which is the same as the number of satellite beams involved along the transportation route;

[0035] The network controller is electrically connected to the modulation and demodulation module, and the outbound router, the inbound router and the hub are all electrically connected to the network controller;

[0036] Each satellite beam involved in the transportation route corresponds to one outbound router, one inbound router and one hub, the outbound router is communicatively connected to the uplink of the corresponding satellite beam, and the inbound router is communicatively connected to the downlink of the corresponding satellite beam;

[0037] The hub is used to perform data broadcasting in the intranet of the transportation vehicle; the network controller is used to call the outbound router, inbound router and hub corresponding to the target satellite beam according to the adjustment instruction, and send network access information after successful network access, and send network failure information when network access is not successful;

[0038] This solution ensures the normal satellite communication link by setting up a network controller in the main network, and the network controller is connected to an outbound router and an inbound router, and broadcasting data is executed through a hub.

[0039] In a possible implementation manner, the network controller is configured to operate as follows:

[0040] When the current position of the transportation tool is covered by only one satellite beam, the outbound router corresponding to the satellite beam is called to perform the next hop of the Internet interaction address of the current communication network of the transportation tool to the network of this satellite beam, and the inbound router and hub corresponding to this satellite beam are called to run, and network access information is issued after successful network access;

[0041] When the current position of the transport tool is covered by multiple satellite beams, the outbound router corresponding to the satellite beam corresponding to the adjustment instruction is called to perform the next hop of the Internet interaction address of the current communication network of the transport tool to the network of this satellite beam, and the inbound router and hub corresponding to this satellite beam are called to run, and then it is determined whether the network is successfully accessed. If so, network access information is sent to the modem module; if not, network non-access information is sent to the modem module;

[0042] This solution adjusts the network access strategy according to different beam coverage conditions, ensuring that the transportation vehicle can access the network normally after switching the satellite beam.

[0043] Another technical solution of the present invention is to provide a roaming switching method for a fusion network of satellite baseband technology, the method comprising the following steps:

[0044] S1: a network control module is set in the general network for performing a next hop from the internet interaction address of the current communication network of the transportation means to the network of the target satellite beam according to the routing information protocol;

[0045] S2: storing beam description information and beam priority order of satellite beams involved in the transportation in the modem module;

[0046] S3: Based on the beam description information and the beam priority order, the modem module receives the location information obtained by the positioning module, and issues an adjustment instruction when the transportation vehicle moves from the coverage area of ​​one satellite beam to the coverage area of ​​another satellite beam;

[0047] S4: adjusting the position and / or angle of the satellite antenna according to the content of the adjustment instruction by the control module so that the satellite antenna locks the target satellite;

[0048] S5: The network control module performs the next hop of the Internet interaction address of the current communication network of the transportation tool to the network of the target satellite beam according to the routing information protocol, and sends network access information after successful network access, and sends network non-access information when network access is not successful.

[0049] The method disclosed in the present invention sets a network control module by executing step S1, stores beam description information and beam priority order by executing step S2, then uses a modulation and demodulation module to receive the position information obtained by the positioning module, and issues an adjustment instruction when beam switching is required, and then uses a control module to adjust the position and / or angle of the satellite antenna according to the content of the adjustment instruction so that the satellite antenna locks the target satellite, thereby overcoming the technical defect of manually adjusting the angle or position of the satellite antenna in the prior art. At the same time, by setting the network control module to perform the next hop of the Internet interaction address of the current communication network of the transportation tool to the network of the target satellite beam according to the routing information protocol after receiving the adjustment instruction, the technical defect of frequently replacing the Internet interaction address is overcome, and the transportation efficiency is improved.

[0050] In a possible implementation, step S1 includes the following steps:

[0051] S11: a network controller having a number of pins matching the number of satellite beams involved in the transportation is set in the general network, and one satellite beam corresponds to one outbound router, one inbound router and one hub;

[0052] S12: establishing electrical connections between the network controller and the modem module, the outbound router, the inbound router, and the hub;

[0053] S13: respectively enabling each of the outbound routers to communicate and connect to the uplink of the corresponding satellite beam, and each of the inbound routers to communicate and connect to the downlink of the corresponding satellite beam;

[0054] S14: respectively configure the uplink frequency, downlink frequency, outgoing symbol rate, modulation mode, error correction mode, demodulation threshold, and routing information of the corresponding satellite beam in each of the hubs, thereby completing the setting of the network control module.

[0055] This solution ensures the normal operation of the hub and the orderly operation of the communication link by connecting to the network and storing satellite data such as uplink frequency and downlink frequency. BRIEF DESCRIPTION OF THE DRAWINGS
