Description

Technical Field

[0001] This utility model relates to the field of communication technology, specifically to a monitoring and command system based on BeiDou and a self-organizing network. Background Technology

[0002] The BeiDou Navigation Satellite System (hereinafter referred to as the BeiDou system) is a satellite navigation system independently constructed and operated by China to meet the needs of national security and economic and social development. The BeiDou system consists of three parts: space segment, ground segment, and user segment. It can provide high-precision and high-reliability positioning, navigation, and timing services to various users around the world, 24 / 7, and has unique short message communication capabilities.

[0003] Ad-hoc / mesh network technology originated from military communication needs such as the ALOHA network in 1968 and has now expanded to the civilian sector. Its core characteristics include decentralization, self-organization, and multi-hop transmission, with nodes serving as both data terminals and routing relays.

[0004] With the emergence of various BeiDou terminals and self-organizing network terminals on the market, their basic usage involves each terminal performing its function independently. BeiDou terminals provide positioning and short message communication, while self-organizing network terminals provide self-organizing network communication. Currently, in environments without terrestrial networks, the supervision and command of dispersed team operations faces the following challenges:

[0005] Limited communication coverage: The lack of terrestrial network means that conventional communication facilities such as base stations and fiber optics cannot be relied upon. In some remote mountainous areas, oceans, deserts and other areas, ordinary communication methods are difficult to cover, which makes it impossible for team members to establish a stable connection with the monitoring and command center, and information transmission is hindered.

[0006] Unstable communication quality: Even with alternative methods such as satellite communication, signals are easily interfered with and attenuated under adverse weather conditions, leading to a decline in communication quality and problems such as signal interruption, data packet loss, and voice interruption, which affect the timely issuance of regulatory instructions and the accurate reporting of operational information.

[0007] High communication costs: Using non-terrestrial network communication methods such as satellite communication has high equipment procurement costs and relatively expensive communication fees, especially for team operation scenarios with long-term and large-volume data transmission, where communication costs can become a heavy burden.

[0008] Insufficient positioning accuracy: Without the assistance of a terrestrial network, the accuracy of some positioning methods may not meet the needs of supervision and command.

[0009] Real-time tracking lag: The lack of effective network support affects the real-time acquisition of team member location information. Traditional location information transmission relies on networks; without terrestrial networks, data transmission delays increase, preventing the monitoring and command center from promptly understanding the latest location and movement trajectory of personnel. In responding to emergencies or when rapid decision-making is required, information lag may cause delays. Utility Model Content

[0028] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to the embodiments and accompanying drawings. The illustrative embodiments and descriptions of this utility model are only used to explain this utility model and are not intended to limit this utility model.

[0029] like Figures 1-3 As shown, this embodiment 1 provides a monitoring and command system based on BeiDou and a self-organizing network, including a BeiDou self-organizing network monitoring and command terminal and multiple BeiDou self-organizing network terminals. The BeiDou self-organizing network monitoring and command terminal serves as the central node, and the BeiDou self-organizing network terminals serve as sub-nodes. The BeiDou self-organizing network terminals and the monitoring and command terminal communicate with each other through BeiDou or a self-organizing network.

[0030] This embodiment uses a star topology for its monitoring and command system based on BeiDou and a self-organizing network. The system mainly comprises multiple (up to 1000+) BeiDou self-organizing network terminals and one BeiDou self-organizing network monitoring and command terminal. After a sub-node successfully connects to the central node, the central node receives the location information reported by the sub-node and can monitor its dynamics. Simultaneously, it can issue command instructions to the sub-nodes, which maintain constant communication with the central node. Due to the limited range of the self-organizing network, when a sub-node exceeds the network range of the central node, it can contact the central node through the BeiDou module and report its real-time location and situation. The BeiDou self-organizing network monitoring and command terminal utilizes monitoring software for real-time monitoring. The software includes a map to easily display the locations of sub-nodes, as well as the monitoring terminal's own location. Clicking on a sub-node on the map allows users to view its details and send messages, achieving the monitoring and command function.

[0031] The BeiDou self-organizing network terminal includes a first BeiDou module, a first self-organizing network module, a first antenna module, and a first central processing unit (CPU).

The first BeiDou module supports high-precision positioning with an error of approximately 10cm. The first antenna module includes a BeiDou RD antenna, an RN antenna, and a self-organizing network antenna. The first self-organizing network module provides networking functionality. In this network, each BeiDou self-organizing network terminal can quickly and successfully network with the second self-organizing network module of the BeiDou self-organizing network monitoring and command terminal through the self-organizing network module, enabling communication after successful networking. The first CPU controls the coordinated operation of the various modules in the BeiDou self-organizing network terminal, controls the power-on and power-off of the first BeiDou module and the first self-organizing network module, controls user input and output, and controls button responses, etc.

[0032] The BeiDou self-organizing network terminal also includes a first power management module and a first storage module, which are respectively connected to a first central processing unit. The first power management module can realize functions such as voltage regulation, power distribution, charge and discharge management, overcharge and over-discharge protection, and battery capacity detection. The first storage module is used to store and manage the data of the BeiDou self-organizing network terminal.

[0033] The BeiDou self-organizing network terminal also includes a display module, a first alarm module, and a button module, all of which are connected to a first central processing unit. The display module can be a touchscreen, providing users with visual operation. The first alarm module is used to trigger alarms and issue alarm signals when the device's battery is low, when the first BeiDou module or the first self-organizing network module malfunctions, when the network fails, or when certain conditions set by the control center are exceeded. These alarm signals can be visual, auditory, or vibration-based prompts. The button module includes a power button, a network button, and a reporting button.

[0034] The BeiDou self-organizing network monitoring and command terminal includes a second BeiDou module, a second self-organizing network module, a second antenna module, and a second central processing unit (CPU). The second BeiDou module, the second self-organizing network module, and the second antenna module are all connected to the second CPU. The second self-organizing network module acts as the network's central node, providing networking functionality for other network sub-nodes to connect to. The BeiDou self-organizing network monitoring and command terminal is equipped with corresponding monitoring and command software to perform its monitoring and command functions. The second CPU is used to control the coordinated operation of the various modules in the BeiDou self-organizing network monitoring and command terminal, control the power-on and power-off of the second BeiDou module and the second self-organizing network module, control user input and output, and manage button responses, etc.

[0035] The second BeiDou module includes RDSS and RNSS, used to send positioning and short message information to BeiDou self-organizing network terminals. The second antenna module includes a BeiDou RD antenna, an RN antenna, and a self-organizing network antenna. RDSS is the short message module, and RNSS is the positioning module, used to send positioning and short message information to BeiDou self-organizing network terminals. The second BeiDou module supports high-precision positioning with an error of about 10cm.

[0036] The BeiDou self-organizing network monitoring and command terminal also includes a second power management module and a second storage module, both connected to a second central processing unit. The second power management module performs functions such as voltage regulation, power distribution, charge / discharge management, overcharge / overdischarge protection, and battery capacity detection. The second storage module stores and manages the data from the BeiDou self-organizing network monitoring and command terminal.

[0037] The BeiDou self-organizing network monitoring and command terminal also includes a display touch module, a second alarm module, and a control button module, all of which are connected to a second central processing unit.

The second alarm module triggers alarms and issues alarm signals when the device's battery is low, when the second BeiDou module or the second self-organizing network module malfunctions, when the network fails, or when a sub-node loses network access. These alarm signals can be visual, auditory, or vibration-based prompts. The control button module includes a power button, a network button, and a reporting button.

[0038] The BeiDou self-organizing network possesses autonomous networking capabilities, eliminating reliance on ground communication base stations and other infrastructure. Even in remote areas or extreme situations such as when communication base stations are damaged due to natural disasters, it can still guarantee communication between terminals and between terminals and the monitoring and command terminal, ensuring reliable information transmission. Furthermore, the self-organizing network communication signal has a certain degree of anti-interference capability, enabling stable operation in complex electromagnetic environments and ensuring smooth communication. The BeiDou self-organizing network monitoring and command terminal, as the central point, can centrally manage and monitor multiple distributed BeiDou self-organizing network terminals, acquiring real-time information such as the location and operational status of each terminal. This facilitates unified scheduling and decision-making, enabling efficient resource allocation and collaborative task execution. The BeiDou module itself possesses high-precision positioning capabilities. Each terminal obtains its accurate location through BeiDou positioning and transmits this location information to the monitoring and command terminal, providing precise location data support for monitoring and management. Combined with BeiDou navigation functionality, it provides navigation guidance for the BeiDou self-organizing network terminals. Simultaneously, the BeiDou self-organizing network monitoring and command terminal can also perform path planning and navigation-assisted decision-making based on the location information of each terminal.

[0039] This utility model provides a monitoring and command system based on BeiDou and an ad hoc network. It combines BeiDou positioning, BeiDou short message service, and ad hoc network communication. For short and medium distances, it uses ad hoc network communication, while for long distances, it uses BeiDou communication.
