Description

TECHNICAL FIELD

[0001] The application belongs to the field of satellite communication, and particularly relates to a dynamic network based on Beidou short message communication and a networking method. BACKGROUND

[0002] The most common and most widely used networking is the Internet, which completely relies on a large number of computer terminals and Internet base stations, has poor confidentiality, and especially cannot provide network signals for broad sea areas, and cannot meet the use requirements.

[0003] The Beidou satellite navigation system is a satellite navigation system independently constructed and operated by China, which can provide users with positioning, speed measurement, time service, short message communication and other services. The short message communication function is a wireless communication function realized by relying on the Beidou space segment satellite, the Beidou ground segment master control station and the Beidou user segment communication terminal.

[0004] Networking refers to arranging multiple network nodes to form a specific relationship network, so as to facilitate the completion of a certain work. Dynamic networking refers to the real-time change of network nodes, and the dynamic adjustment of nodes according to different use requirements. The implementation of this technology involves the field of Beidou short message communication, and needs to comprehensively use Beidou communication technology, information processing technology and networking communication technology.

[0005] At present, networking using Beidou communication has been widely used, but most of them only use the function of Beidou command (command means broadcasting command information to subordinate users, and collection means simultaneously receiving information of subordinate Beidou users), adopt the fixed (non-dynamic) networking form of Beidou command machine + Beidou ordinary subordinate user machine, and only allow a specific Beidou command machine to command and operate the Beidou subordinate user machine. The information between subordinate user machines cannot be shared, and the subordinate user machines can only report information to the command machine through point-to-point communication mode. Once a Beidou communication terminal becomes a command machine, the network structure is fixed and cannot be flexibly networked. This communication mode has the following defects: packet loss and inconsistent receiving beams lead to communication failure; cannot meet the requirements of multi-user cross-command, subordinate information sharing, flexible dynamic networking, reliable transmission of Beidou information, and has poor reliability; cannot provide all-weather, all-day and all-terrain services. SUMMARY

[0006] The present application aims at overcoming the deficiencies in the prior art, and is based on the Beidou communication terminal with the commander attribute, and constructs the Beidou data communication network system in the form of the command relationship of the subordinate relationship based on the Beidou short message communication principle. Each Beidou communication terminal is a node of the network, and each node can complete the seamless switching between the commander and the ordinary subordinate user in real time, that is, each Beidou communication terminal is used as the commander and the subordinate user of other Beidou communication terminals. When one terminal sends the Beidou short message, other terminals belonging to the subordinate users in the network can receive the short message, and the network can be dynamically formed according to the needs.

[0007] To achieve the above-mentioned application purposes, in the first aspect, the present application provides a dynamic network based on the Beidou short message communication, which comprises a plurality of network nodes with the number being dynamically adjustable. Each network node comprises a Beidou communication terminal, and each Beidou communication terminal is installed with a command card. Each network node is adapted for bidirectional communication.

[0008] Further, each network node is configured to be adapted for real-time seamless switching between the commander and the subordinate machine.

[0009] Further, any part of the network node is adapted to form a task subnetwork.

[0010] Further, only one fixed network node in the task subnetwork is configured as the commander, and other network nodes are configured as the subordinate machine.

[0011] Further, the commander is installed with a visual software module for network configuration information, which is adapted to edit the network application information and send the network application information in the form of the short message. The network application information comprises the command card ID number of the Beidou communication terminal of at least one network node which needs to join the task subnetwork. The subordinate machine is adapted to identify whether the command card ID number of itself is contained in the network application information. If yes, the subordinate machine feeds back the confirmation information to the commander. After receiving the confirmation information, the commander adds the network node where the subordinate machine is located to the task subnetwork.

[0012] Further, the commander is adapted to monitor any member in the task subnetwork in real time.

[0013] Further, the real-time monitoring comprises the requirement of sharing the position and reporting the state.

[0014] In the second aspect, the present application provides a dynamic network forming method based on the Beidou short message communication, which comprises a plurality of Beidou communication terminals installed with the command card as different network nodes, and makes each network node perform bidirectional communication.

[0015] Further, any part of the network nodes constitutes a task sub-network; only one fixed network node in the task sub-network is configured as a commander, and other network nodes are configured as subordinate machines.

[0016] Further, the network forming process of the task sub-network is that the commander sends network forming application information to each subordinate machine in the form of a short message, the subordinate machine identifies whether the network forming application information contains its own commander card ID number, if yes, it feeds back confirmation information to the commander, and the commander adds the network node where the subordinate machine is located to the task sub-network after receiving the confirmation information.

[0017] Compared with the prior art, the application has the following beneficial effects:

[0018] 1. Based on the Beidou short message communication principle, the Beidou data communication network system is constructed by taking the commander relationship of mutual subordinate relationship, each Beidou communication terminal is a node of the network, and each node can complete seamless switching between the commander and the ordinary subordinate user machine in real time, that is, each Beidou communication terminal is not only a commander, but also a subordinate user of other Beidou communication terminals, when one terminal sends a Beidou short message, other terminals belonging to the subordinate users of the terminal can receive the short message, and the network can be dynamically formed according to the needs.

[0019] 2. The dynamic network formed by using the Beidou short message communication has the characteristics of all-weather, all-day, and all-terrain service, and the communication reliability is greatly improved through the information sending in the form of Beidou broadcast, and the success rate reaches 99%, and the encrypted data transmission can be provided for specific users, so that the privacy of the dynamic network is greatly ensured.

[0020] 3. The user can select part of the nodes in the Beidou data communication network to form a specific local network relationship, and the information sharing, command monitoring, position reporting and other operations are implemented for the network members, so that the dynamic network function among different users in the Beidou data communication network can be realized, and the needs of strong mobility, cross-command, flexible network relationship and the like of the cluster operation are met. BRIEF DESCRIPTION OF DRAWINGS

[0022] Figure 2 It is a network forming flowchart of the task sub-network in one embodiment of the dynamic network / network forming method of the application. DETAILED DESCRIPTION

[0023] The technical solutions of the application will be further described in combination with the drawings and specific embodiments.

[0024] To meet the needs of cluster job maneuverability, cross-command, networking relationship flexibility, users can select some nodes from the Beidou data communication network to form a specific local networking relationship. For members in the network, information sharing, command and monitoring, position reporting and other operations are implemented, so as to realize the function of dynamic networking between different users in the Beidou data communication network. Beidou short message communication relies on Beidou communication terminal with command machine attribute, and based on the principle of Beidou short message communication, Beidou short message receiving and processing, broadcast sending processing can be completed. Beidou short message communication adopts broadcast sending mode, and Beidou communication information is sent in full beam to ensure that target users can still stably receive Beidou communication information in weak signal areas, and the reliability is good.

[0025] Dynamic networking is to build a Beidou data communication network system by adopting mutual subordinate command relationship. Each Beidou communication terminal is a node of the network, and each node can realize seamless switching between command machine and ordinary subordinate user machine in real time. According to the use demand, some nodes in the Beidou data communication network can be arranged to build a specific networking relationship, so as to realize the function of dynamic networking. The Beidou communication terminal can realize real-time identity switching of command user or ordinary subordinate user. The identity switching means that the Beidou communication terminal can identify the Beidou command card as a Beidou command type communication terminal, or identify the Beidou ordinary card as a Beidou ordinary type communication terminal. The reliable Beidou short message communication means that the Beidou communication information is sent in full beam in broadcast form to ensure that the target user can effectively receive the communication information. The broadcast form means that the Beidou short message communication is sent from all Beidou communication channels, and the full beam means all Beidou communication channels. The dynamic networking can arrange some nodes in the Beidou data communication network to build a specific networking relationship according to the use demand, so as to realize flexible networking.

[0026] As shown in Figure 1 The Beidou communication data network is composed of three Beidou communication terminals, each of which is a node in the network, each node is equipped with a Beidou command chip to become a Beidou command machine, and each node is also a subordinate user of the remaining nodes.

[0027] When the first node sends Beidou communication information in the form of Beidou broadcast, the second node and the third node are subordinate users of the first node, so the second node and the third node can receive the Beidou communication information sent by the first node. Similarly, when the second node or the third node sends Beidou communication information in the same way, the remaining two nodes can also receive the corresponding Beidou communication information because they are subordinate users. In this way, a minimized Beidou communication data network is established through the transmission of Beidou communication data.

[0028] The above reasoning can be extended to design, that is, assuming that the number of Beidou communication terminals increases to hundreds or even more, a larger Beidou data communication network can be established. Each Beidou communication terminal in the Beidou data network serves as a node. Users can configure some nodes in the Beidou data communication network to form specific task groups according to different usage scenarios and needs, and use the ID number of the Beidou chip as the access password for the specific group. In this way, the function of dynamic networking can be realized in the Beidou data communication network.

[0029] Take the position reporting system as an example, Figure 1 As shown in the figure, the position reporting system is composed of three Beidou communication terminals, each of which is both the command terminal of the remaining two Beidou communication terminals and the subordinate user terminal of the remaining Beidou communication terminals. In this way, the three Beidou communication terminals form a small Beidou communication data network for position reporting. The usage flow chart is shown in the figure. Figure 2 After the equipment is powered on, first determine the command terminal, then configure the Beidou communication terminal that needs to be networked or the carrier carrying the Beidou communication terminal through the command terminal control software, use the Beidou ID of each Beidou communication terminal as the entry identity password and edit it into the network management information, and then the command terminal uses the Beidou short message to apply for grouping to the corresponding Beidou user who needs to join the grouping. After the device requested to join the network receives the grouping request from the command terminal, it compares whether the grouping request information contains the device ID, and feeds back the correct grouping request confirmation information (including the local ID information, confirmation of joining the grouping response information, etc.) to the command terminal. After the command terminal receives the confirmation information, the entire grouping process is completed. After the grouping is completed, the members in the group can be managed, including requirements for sharing location, reporting status, etc., so that dynamic networking operations can be effectively completed according to usage needs.

[0030] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention and not to limit it. Although the present invention has been described in detail with reference to the above embodiments, ordinary technicians in the field should understand that the specific implementation methods of the present invention can still be modified or replaced by equivalents. Any modification or equivalent replacement that does not depart from the spirit and scope of the present invention should be covered by the scope of protection of the claims of the present invention.
