Abstract
Description
Technical Field
[0001] This invention belongs to the field of space optical communication technology, specifically relating to a centralized link scheduling method for a local wireless laser integrated terminal of a space on-orbit service platform. Background Technology
[0002] With the rapid development of space communication technology and large-scale on-orbit structures (such as space stations, deployable antenna arrays, and on-orbit service platforms), the demand for high-bandwidth, low-latency, and highly secure local communication networks is becoming increasingly urgent. Laser communication, with its advantages of high bandwidth, low power consumption, strong resistance to electromagnetic interference, and good confidentiality, has become an ideal choice for building high-speed space information networks. At the same time, the maturity of integrated laser communication, energy transmission, and ranging technologies has enabled single laser terminals to possess multi-functional integration capabilities, further enhancing the overall system efficiency.
[0003] Large-scale space structures typically deploy a large number of mobile, reconfigurable integrated terminal nodes. These nodes may change location due to mission adjustments, equipment replacements, or structural deployments, and their number may also dynamically increase or decrease. Laser communication is characterized by strong directionality, narrow beamwidth, and extremely high alignment accuracy requirements, which makes the establishment and maintenance of links between nodes, as well as rapid autonomous reconfiguration after link loss, key challenges in networking technology.
[0004] Currently, most common space laser networking solutions rely on radio frequency (RF) relays or hybrid optoelectronic links, with network coordination handled by a central control node. While these methods achieve network management to some extent, they introduce RF signals, leading to electromagnetic compatibility issues, susceptibility to interference, and the risk of information leakage, making them unsuitable for the pure optical communication requirements of high-security scenarios. While using laser links exclusively for networking can avoid RF interference and improve security, the lack of traditional RF or wired signaling channels during initial node installation or link interruptions makes it difficult for nodes to re-establish connections and coordination, resulting in network initialization failures or paralysis. Furthermore, the system's self-organization and self-healing capabilities are insufficient.
[0005] Therefore, there is an urgent need to research a centralized scheduling method that enables autonomous node discovery, rapid network formation, and intelligent reconfiguration under pure laser link conditions. This method needs to solve the "blind search" problem of laser networks in dynamic environments without relying on external radio frequency or wired control channels, and achieve autonomous coordination and stable maintenance of the network topology, thereby significantly improving the reliability, security, and mission adaptability of large-scale space communication networks. Summary of the Invention
[0006] To address the aforementioned technical problems, this invention provides a centralized link scheduling method for a local wireless laser integrated terminal in a space on-orbit service platform. By introducing a link scheduling unit for the wireless laser integrated terminal and designing wireless laser link scheduling logic for both the wireless laser integrated terminal link scheduling unit and the wireless laser integrated terminal unit, autonomous link establishment and dynamic topology maintenance are achieved. This enables stable networking and robust reconfiguration of large-scale space-based local area networks without relying on radio frequency relays, thereby improving the system's security and reliability.
[0007] To achieve the above objectives, the present invention adopts the following technical solution:
[0008] A centralized link scheduling method for a local wireless laser integrated terminal of a space on-orbit service platform includes:
[0009] Under the control of the wireless laser link scheduling logic unit, the wireless laser integrated terminal link scheduling unit emits a detection laser through its first single-pendulum mirror integrated laser terminal, and uses its omnidirectional reflector array to return the incident laser from the wireless laser integrated terminal unit along the original path. It discovers and records the location and identification information of at least one of the wireless laser integrated terminal units through spatial scanning.
[0010] Based on the discovered and recorded information and the preset networking strategy, the wireless laser integrated terminal link scheduling unit generates and sends a link establishment scheduling instruction to the corresponding wireless laser integrated terminal unit.
[0011] Under the control of the wireless laser link scheduling logic unit, the wireless laser integrated terminal unit actively searches for and locks onto the direction of the wireless laser integrated terminal link scheduling unit. After receiving the scheduling instruction, it adjusts its own beam direction to establish a laser communication link with the target node and returns confirmation information.
[0012] Furthermore, the wireless laser integrated terminal unit consists of at least one second single-pendulum mirror wireless laser integrated terminal; when the wireless laser integrated terminal unit includes multiple second single-pendulum mirror wireless laser integrated terminals, each second single-pendulum mirror wireless laser integrated terminal is locally networked through a wired local area network, enabling the wireless laser integrated terminal unit to have one-to-many communication capability; each wireless laser integrated terminal unit has at least one wireless laser integrated terminal link scheduling unit within its field of view.
[0013] Furthermore, the wireless laser integrated terminal link scheduling unit includes an omnidirectional reflector array, a first single-pendulum integrated laser terminal, and a connector; the omnidirectional reflector array and the connector are connected by bolts, and the first single-pendulum integrated laser terminal and the connector are connected by bolts; the laser emission directions of the omnidirectional reflector array and the first single-pendulum integrated laser terminal do not interfere with each other.
[0014] Furthermore, the wireless laser link scheduling logic unit includes a scheduling-side logic flow running on the wireless laser integrated terminal link scheduling unit, and a terminal-side logic flow running on the wireless laser integrated terminal unit; wherein,
[0015] The scheduling side logic flow includes a wireless laser integrated terminal unit traversal process and an instruction issuance process. The wireless laser integrated terminal unit traversal process is used to find wireless laser integrated terminal units waiting to form a network and obtain their installation location information. The instruction issuance process is used to issue a link establishment scheduling instruction to the wireless laser integrated terminal unit.
[0016] The terminal-side logic flow includes a scheduling unit search flow and an instruction response flow. The scheduling unit search flow is used to enable the wireless laser integrated terminal unit to initially align with the wireless laser integrated terminal link scheduling unit. The instruction response flow is used to enable the wireless laser integrated terminal unit to respond to and execute the received link establishment scheduling instruction.
[0017] Furthermore, the traversal process of the wireless laser integrated terminal unit specifically includes:
[0018] The wireless laser integrated terminal link scheduling unit reads the preset scanning path and controls its first single-pendulum mirror integrated laser terminal to scan along the scanning path.
[0019] When a transmission signal is received from any wireless laser integrated terminal unit at the scanning point, align with the signal and record the location information of the wireless laser integrated terminal unit at this location to establish a list of wireless laser integrated terminal units to be networked.
[0020] Repeat the above steps until all preset scan path points have been traversed.
[0021] Furthermore, the instruction issuance process specifically includes:
[0022] The wireless laser integrated terminal link scheduling unit sends a link establishment scheduling instruction containing node identifier, link establishment parameters and target attitude angle to each wireless laser integrated terminal unit according to the list of wireless laser integrated terminal units to be networked.
[0023] If no confirmation signal is received from the wireless laser integrated terminal unit within the specified time, an attempt is made to resend the link establishment scheduling command. If multiple attempts fail, the corresponding wireless laser integrated terminal unit is marked as abnormal and removed from the link.
[0024] Furthermore, the scheduling unit search process specifically includes:
[0025] When the wireless laser integrated terminal unit is initially powered on or experiences a long-term disconnection that cannot be recovered, it periodically swings its second single-pendulum mirror-type wireless laser integrated terminal to achieve beam coverage within the field of view and search for the reflected signal of the wireless laser integrated terminal link scheduling unit.
[0026] Based on the detected reflected signal, the direction of the wireless laser integrated terminal link scheduling unit is locked, and the system waits for the link establishment scheduling command to be issued.
[0027] Furthermore, the instruction response process specifically includes:
[0028] When the wireless laser integrated terminal unit successfully receives the scheduling instruction signal from the wireless laser integrated terminal link scheduling unit, it immediately sends a response frame to confirm receipt.
[0029] Perform beam alignment and laser link establishment operations according to the scheduling instructions;
[0030] If a laser communication link cannot be successfully established with the target node, the scheduling unit search process is restarted.
[0031] In a second aspect, the present invention provides an electronic device, comprising: one or more processors; and a memory for storing one or more programs; wherein, when the one or more programs are executed by the one or more processors, the one or more processors implement the aforementioned link-centralized scheduling method for a local wireless laser integrated terminal of a space on-orbit service platform.
[0032] Thirdly, the present invention provides a computer-readable storage medium having executable instructions stored thereon, which, when executed by a processor, enable the processor to implement the aforementioned centralized link scheduling method for a local wireless laser integrated terminal of a space on-orbit service platform.
[0033] The beneficial effects of this invention are as follows:
[0034] Achieving all-optical autonomous networking with high security: It abandons traditional radio frequency relays or hybrid links, relying entirely on laser links to complete signaling interaction and data transmission, fundamentally eliminating the risks of radio frequency leakage and electromagnetic interference, significantly improving the confidentiality and anti-interference capabilities of communication, and is suitable for space mission environments with high security requirements.
[0035] It possesses intelligent scheduling and rapid reconfiguration capabilities: By introducing a dedicated link scheduling unit and its corresponding scheduling process, it achieves automatic discovery, centralized coordination, and command issuance of network nodes. The system can autonomously and rapidly complete network topology reconfiguration and link recovery when node locations change dynamically or link interruptions occur, greatly enhancing the network's self-organization and robustness.
[0036] Simplified node alignment and initial link establishment process: The scheduling unit adopts an omnidirectional reflector array design, which can return the probe laser along the original path, providing a clear optical beacon for the terminal to be networked, simplifying the initial search and alignment process, reducing the dependence on the initial attitude and absolute positioning accuracy of the terminal, and improving the success rate and efficiency of network establishment.
[0037] The system boasts a simple structure and enhanced reliability: the core scheduling unit is compact, integrating the reflective beacon and communication terminal into a single unit.

[0049] The present invention will be further described below with reference to the accompanying drawings and embodiments.
[0050] This invention provides a centralized link scheduling method for a local wireless laser integrated terminal of a space on-orbit service platform. Throughout the entire process of node discovery, link establishment, command interaction, and link recovery, information exchange and control are achieved solely through the laser link, without relying on any radio frequency communication, external positioning information, or manual pre-calibration methods. This constructs a fully laser-based local communication network scheduling method suitable for space on-orbit service platforms, significantly improving system security, anti-interference capabilities, and on-orbit deployment flexibility. This method addresses the problems of existing space communication networks, which typically rely on radio frequency broadcasting, wired control buses, or hybrid communication methods for initial link establishment and scheduling control during node discovery, network control, and link reconfiguration. These methods suffer from high radio frequency interference risks, high system complexity, and limited security.
[0051] like Figure 1As shown, the centralized link scheduling method for a local wireless laser integrated terminal in a space on-orbit service platform relies on at least one wireless laser integrated terminal link scheduling unit 1, several wireless laser integrated terminal units 2, and a wireless laser link scheduling logic unit 3. The wireless laser integrated terminal link scheduling unit 1 and the wireless laser integrated terminal units 2 respectively run the scheduling logic in the wireless laser link scheduling logic unit 3. The wireless laser integrated terminal link scheduling unit 1 is fixedly installed on the substrate of a large space structure, serving as a centralized scheduling node in the local laser communication network. It is responsible for uniformly maintaining the spatial location information, link status, and topology relationships of each wireless laser integrated terminal unit 2 within the network, and for centrally coordinating and controlling the link establishment order, communication resource allocation, and link reconstruction process. Each wireless laser integrated terminal unit 2 only executes the corresponding alignment and link establishment operations according to the scheduling instructions issued by the wireless laser integrated terminal link scheduling unit 1, without participating in global topology decisions. This avoids link contention, scheduling conflicts, and topology instability problems that may occur in distributed autonomous networks, reduces the control complexity on the terminal side, and improves the overall system controllability and reliability. The wireless laser integrated terminal units 2 can be installed manually or automatically at different locations on the large space structure. The wireless laser link scheduling logic unit 3 can be physically integrated into the two units mentioned above, or it can exist and operate as an independent control module. Its essence is a hardware and software entity that runs centralized scheduling algorithms and processes, used for link establishment, topology coordination, and link loss recovery.
[0052] Preferably, such as Figure 2As shown, the wireless laser integrated terminal link scheduling unit 1 includes an omnidirectional reflector array 101, a first single-pendulum mirror-type integrated laser terminal 102, and a connector 103. The omnidirectional reflector array 101 is used to return the incident light along its original path, so that the wireless laser integrated terminal unit 2 can achieve initial optical axis alignment. By setting the omnidirectional reflector array 101 on the wireless laser integrated terminal link scheduling unit 1, the wireless laser integrated terminal unit 2 can still acquire the laser signal reflected back by the omnidirectional reflector array 101 by scanning even when no communication link has been established and the precise attitude and position of the scheduling unit are unknown, thereby achieving passive capture and initial alignment of the direction of the wireless laser integrated terminal link scheduling unit 1. This method does not require additional active beacon light sources on the scheduling unit side, nor does it rely on the prior attitude information of the terminal unit or an external positioning system, and can achieve automatic link establishment in any state after the terminal unit is initially powered on, reinstalled, or after a link loss. Compared to node discovery methods using active optical beacons or radio frequency broadcasts, the passive reflection mechanism implemented by the omnidirectional mirror array 101 in this invention has the advantages of simple structure, low energy consumption, and high reliability. It is especially suitable for application scenarios in space on-orbit service platforms where there are many nodes, their deployment locations are dispersed, and maintenance conditions are limited. The first single-pendulum mirror integrated laser terminal 102 is used to perform laser scanning, link establishment, and command issuance. The connector 103 is used to mechanically fix the omnidirectional mirror array 101 and the first single-pendulum mirror integrated laser terminal 102. The laser emission directions of the omnidirectional mirror array 101 and the first single-pendulum mirror integrated laser terminal 102 are independent of each other and do not interfere with each other.
[0053] Preferably, such as Figure 3 As shown, the wireless laser integrated terminal unit 2 consists of at least one second single-pendulum mirror-type integrated laser terminal 201, used to establish a laser communication link with the wireless laser integrated terminal link scheduling unit 1 or the wireless laser integrated terminal unit 2. When it contains multiple terminals, the terminals can achieve local networking through a wired local area network, enabling the unit to have one-to-many communication capability. The second single-pendulum mirror-type integrated laser terminal 201 drives the reflector through an actuator to achieve rapid scanning of the beam angle, in order to search for the reflected signal returned by the wireless laser integrated terminal link scheduling unit 1 or the emission signal of other target wireless laser integrated terminal units 2 to achieve beam alignment.
[0054] The scheduling process executed by the wireless laser link scheduling logic unit 3 mainly includes the process running on the side of the wireless laser integrated terminal link scheduling unit 1 and the process running on the side of the wireless laser integrated terminal unit 2, which together realize the two major functions of initial link establishment and link failure recovery, as follows:
[0055] Firstly, the process on the scheduling unit side:
[0056] (1) Wireless laser integrated terminal unit traversal process, used to discover the wireless laser integrated terminal unit 2 to be networked; such as Figure 4 As shown, after the wireless laser integrated terminal link scheduling unit 1 is started, it reads the preset spatial scanning path and controls the first single-pendulum mirror integrated laser terminal 102 to scan along the path points. The spatial scanning path can be pre-planned according to the geometric shape of the large spatial structure and the possible installation area of the wireless laser integrated terminal unit 2. Preferably, it is a partitioned scanning path, a spiral scanning path, or a multi-level resolution scanning path covering the target spatial area. The wireless laser integrated terminal link scheduling unit 1 can mark the discovered wireless laser integrated terminal units 2 according to the scanning results and confirm the consistency of repeatedly captured reflected signals to improve the reliability of node discovery and avoid misidentification. Through the above-mentioned traversal scanning strategy, it is possible to achieve comprehensive and stable discovery and positioning of the wireless laser integrated terminal units 2 to be networked while ensuring scanning efficiency. If a laser signal emitted by the wireless laser integrated terminal unit 2 is received at a certain point, the position of the wireless laser integrated terminal unit 2 at that point is aligned with the signal and recorded, and a list of wireless laser integrated terminal units to be networked is established. This process is repeated until all path points have been traversed. This process can realize automatic traversal and positioning of all nodes to be accessed, providing basic information for subsequent scheduling.
[0057] (2) Instruction issuance process; such as Figure 5 As shown, the instruction issuance process runs on the wireless laser integrated terminal link scheduling unit 1 and is initiated after completing the traversal process from the optical transceiver. The wireless laser integrated terminal link scheduling unit 1 issues networking instructions to each wireless laser integrated terminal unit 2 according to the list of wireless laser integrated terminal units to be networked. This instruction includes information such as node identifier, link establishment parameters, and target attitude angle. Upon receiving the networking instruction, the wireless laser integrated terminal unit 2 first responds to the instruction, and then adjusts the attitude of its second single-pendulum mirror integrated laser terminal 201 according to the instruction content to achieve rapid alignment with the target wireless laser integrated terminal unit 2. If no confirmation signal is received from the wireless laser integrated terminal unit 2 within a specified time, the wireless laser integrated terminal link scheduling unit 1 will attempt to reissue the process. If multiple attempts fail, the wireless laser integrated terminal unit 2 is marked as abnormal and removed from the link. The wireless laser integrated terminal link scheduling unit 1 continuously repeats this process until all links are successfully established. This process is a centralized coordination link for the entire system, ensuring the reasonable allocation of networking order, link numbering, and communication resources among the nodes.
[0058] Secondly, the terminal unit side process (triggered and controlled by wireless laser link scheduling logic unit 3):
[0059] (1) The scheduling unit search process, such as Figure 6 As shown, the scheduling unit search process runs inside the wireless laser integrated terminal unit 2 and is automatically initiated. When the wireless laser integrated terminal unit 2 is initially powered on or after a long period of disconnection that cannot be recovered, it periodically swings the second single-pendulum mirror integrated laser terminal 201 to achieve beam coverage within the field of view, thereby searching for the reflection signal of the omnidirectional reflector array 101 of the wireless laser integrated terminal link scheduling unit 1, and locks the direction of the scheduling unit based on the signal, waiting for the link establishment command to be issued.
[0060] (2) Command response process, such as Figure 7 As shown, the instruction response process operates within the wireless laser integrated terminal unit 2. When the wireless laser integrated terminal unit 2 successfully receives the scheduling instruction signal from the wireless laser integrated terminal link scheduling unit 1, it immediately sends a response frame to confirm receipt of the instruction. Based on the instruction, it adjusts the beam direction of the second monopole mirror integrated laser terminal 201, performs alignment and laser link establishment operations, and attempts to establish a laser communication link. If a laser link cannot be established with the target unit, the scheduling unit's search process is restarted to wait for subsequent link establishment instructions.
[0061] Through the coordinated operation of the above four processes, this invention can achieve automatic node discovery, centralized command scheduling, and stable communication link establishment under pure laser link conditions, thereby supporting the efficient networking and dynamic maintenance of large-scale space laser communication networks.

[0063] Thirdly, the present invention provides a computer-readable storage medium having executable instructions stored thereon, which, when executed by a processor, enable the processor to implement the aforementioned centralized link scheduling method for a local wireless laser integrated terminal of a space on-orbit service platform.
