Description

Technical Field

[0001] This invention relates to the field of emergency communication technology, specifically to a self-organizing network and resilience system for emergency communication in chemical enterprises. Background Technology

[0002] Emergency communication technology is a core support for accident handling and emergency drills in chemical enterprises, directly affecting the efficiency and safety of rescue operations. Chemical production processes involve large quantities of flammable, explosive, toxic, and hazardous chemicals. After an accident, the on-site environment quickly becomes extremely complex—strong electromagnetic interference from explosions, disruption of fixed communication lines due to building collapses, and signal transmission obstruction by toxic fumes can all have a devastating impact on communication networks, necessitating highly adaptable emergency communication solutions.

[0003] In emergency response scenarios, the drawbacks of traditional communication networks are particularly prominent: on the one hand, their reliance on fixed base stations makes them extremely vulnerable to paralysis under disaster impacts. Once the infrastructure is damaged, the real-time dispatch link between the command center and the rescue site and key positions will be interrupted, severely restricting rescue efficiency; on the other hand, conventional communication equipment lacks special design for chemical environments, has weak anti-interference capabilities, and factors such as high-concentration chemical media and strong electromagnetic radiation can cause a sharp decline in signal quality, resulting in problems such as transmission delays, interruptions, or high bit error rates, which cannot meet the needs of high-definition video and large data transmission in emergency situations.

[0004] To optimize the security of emergency communication self-organizing networks, Chinese patent CN118338291B discloses a method for identity authentication and secure data transmission in an emergency communication wireless mesh self-organizing network. This method simplifies the identity authentication process by sharing a trusted public key and using digital signature technology, and ensures the security of node private keys through a random challenge response mechanism, providing security support for data transmission in the self-organizing network. However, this technical solution only focuses on identity authentication and private key protection, without designing anti-interference characteristics for the strong interference environment at chemical enterprise accident sites, nor considering the high bandwidth transmission capabilities required for emergency communication. It cannot adapt to practical needs such as high-definition video backhaul and multi-node concurrent communication. At the same time, it does not involve the deployment design of mobile communication nodes, making it difficult to address the need to fill communication blind spots at accident sites, and it does not set up a satellite communication backup link. When the ground self-organizing network encounters a large-scale failure, communication continuity cannot be guaranteed, and it still cannot solve the problem of communication resilience in emergency scenarios in chemical enterprises. Summary of the Invention

[0005] To address the problems in existing technologies, such as the vulnerability of fixed base station communication to damage during chemical accidents leading to communication paralysis, and the poor signal quality and high bit error rate of conventional equipment due to the complex environment of chemical sites, this invention provides a self-organizing network and resilience system for emergency communication in chemical enterprises.

[0006] To achieve the above objectives, the technical solution of the present invention is as follows:

[0007] A self-organizing network and resilience system for emergency communication in chemical enterprises includes a self-organizing network infrastructure, a routing optimization module, and a satellite communication backup link system.

[0008] The self-organizing network infrastructure includes multiple networking nodes based on wireless self-organizing network technology. The networking nodes include Mesh routers and emergency communication vehicles. The Mesh routers are set up in key areas of chemical industrial parks or enterprises, and build multi-hop wireless networks through wireless links to monitor signal strength, interference source distribution, and node connection status in real time and feed them back to the network management module. The emergency communication vehicle, as a mobile node, can move to the disaster area as needed to access the network, enhancing local communication coverage and signal strength.

[0009] The routing optimization module incorporates a network topology construction algorithm and a routing optimization strategy. The network topology construction algorithm plans the optimal initial network topology structure based on the topography, building layout, and distribution of potential risk points in the chemical industrial park during the network initialization phase. The routing optimization strategy searches for available nodes and links based on a dynamic routing protocol when node failures, signal interruptions, or strong interference occur, recalculates the optimal communication path, and bypasses faulty nodes to achieve data transmission.

[0010] The satellite communication backup link system includes satellite terminal equipment and supporting communication software. The satellite communication backup link system is normally in hot standby mode and continuously monitors the operation of the ground network. When a large-scale failure of the ground ad hoc network fails and cannot meet the emergency communication needs, it quickly switches to the satellite communication backup link system. The command center's instructions are directly transmitted to the rescue site in remote or severely affected areas through the satellite terminal equipment, while key information from the site is transmitted back to the command center.

[0011] Furthermore, the key areas within the chemical industrial park or enterprise include production workshops, tank areas, warehouses, and office buildings.

[0012] Furthermore, the Mesh router includes a radio frequency module, an internal storage module, and a multi-hop transmission protocol; the radio frequency module has wide bandwidth, high gain, and strong anti-interference capabilities; the internal storage module pre-stores an interference source feature library based on chemical engineering expertise to assist in quickly identifying and responding to interference situations; the multi-hop transmission protocol complies with industry security standards.

[0013] Furthermore, the emergency communication vehicle includes high-performance communication equipment and a vehicle-mounted intelligent power management system; the high-performance communication equipment includes a high-power radio, vehicle-mounted satellite communication equipment, and a multi-band antenna; the vehicle-mounted intelligent power management system can automatically allocate power according to the vehicle's operating status and the power consumption requirements of the high-performance communication equipment.

[0014] Furthermore, the switching threshold parameters of the satellite communication backup link system are dynamically set according to the scale of the chemical enterprise, the risk level, and the reliability of the ground network. The satellite terminal equipment has automatic satellite search and signal strength adaptive adjustment functions, and the communication software supports multi-protocol conversion, realizing seamless connection between satellite communication and ground network communication.

[0015] Compared with the prior art, the beneficial effects of the present invention are as follows:

[0016] This invention discloses a self-organizing and resilient emergency communication network system for chemical enterprises. Through the collaborative design of a self-organizing network infrastructure, a routing optimization module, and a satellite communication backup link system, it deploys wide-bandwidth, high-gain, and highly interference-resistant Mesh routers in key areas such as production workshops and tank areas within chemical industrial parks. Combined with mobile emergency communication vehicles capable of filling gaps, it constructs a multi-hop wireless network. This system utilizes network topology construction algorithms to plan the optimal initial network structure and employs routing optimization strategies to quickly reconstruct communication paths in the event of node failures or strong interference, ensuring continuous data transmission. Simultaneously, a hot-standby satellite communication backup link serves as a safety net, with switching thresholds dynamically set according to the actual situation of the chemical enterprise. Seamless integration with terrestrial networks is achieved through automatic satellite search and multi-protocol conversion. This effectively solves the problems of traditional communication networks relying on fixed base stations, which are prone to failure and have weak anti-interference capabilities. It meets the core requirements of chemical enterprises for highly reliable, resilient, and wide-coverage communication in accident handling and emergency drills, ensuring real-time and uninterrupted transmission of instructions and information feedback between the command center and the rescue site. This provides crucial support for efficient rescue operations and minimizes casualties and property losses caused by accidents. Detailed Implementation

[0017] To make the objectives, technical solutions, and advantages of this invention clearer, the invention is further described in detail below through specific embodiments. It should be understood that the specific embodiments described herein are merely illustrative and not intended to limit the invention.

[0018] A self-organizing network and resilience system for emergency communication in chemical enterprises includes a self-organizing network infrastructure, a routing optimization module, and a satellite communication backup link system.

[0019] The self-organizing network infrastructure comprises multiple network nodes based on wireless self-organizing network technology. These nodes include Mesh routers and emergency communication vehicles. The Mesh routers are deployed in key areas within chemical industrial parks or enterprises, constructing multi-hop wireless networks via wireless links. Each Mesh router possesses the ability to intelligently sense changes in the surrounding environment, monitoring signal strength, interference source distribution, and node connection status in real time and feeding this information back to the network management module. The emergency communication vehicle, as a mobile node, can be moved to disaster-stricken areas as needed to access the network, enhancing local communication coverage and signal strength. It is particularly suitable for filling communication gaps in severely affected areas where fixed nodes are damaged.

[0020] The routing optimization module incorporates a network topology construction algorithm and a routing optimization strategy. The network topology construction algorithm plans the optimal initial network topology based on the topography, building layout, and distribution of potential risk points in the chemical industrial park during the network initialization phase. The routing optimization strategy searches for available nodes and links based on a dynamic routing protocol when node failures, signal interruptions, or strong interference occur. It then recalculates the optimal communication path, bypasses faulty nodes to achieve data transmission, realizes network self-healing, and ensures uninterrupted communication. For example, if a Mesh router near a production workshop is damaged by an explosion, its surrounding nodes will sense the change in a very short time and select other stable nodes to relay data, allowing the command center to maintain contact with rescue personnel in the area.

[0021] The satellite communication backup link system includes satellite terminal equipment and supporting communication software. The satellite communication backup link system is normally in hot standby mode, continuously monitoring the operation of the ground network. When a large-scale failure of the ground ad hoc network fails and cannot meet emergency communication needs, it quickly switches to the satellite communication backup link system. The satellite terminal equipment transmits the command center's instructions directly to the rescue site in remote or severely affected areas, while simultaneously transmitting key information from the site back to the command center. This ensures unimpeded emergency command and dispatch instructions in extreme situations, buying valuable time for rescue operations.

[0022] In one embodiment of the present invention, the key areas within the chemical industrial park or enterprise include production workshops, tank areas, warehouses, and office buildings.

[0023] In one embodiment of the present invention, the Mesh router includes a radio frequency module, an internal storage module, and a multi-hop transmission protocol; the radio frequency module has wide bandwidth, high gain, and strong anti-interference capability; the internal storage module pre-stores an interference source feature library based on chemical engineering expertise to assist in quickly identifying and responding to interference situations; the multi-hop transmission protocol complies with industry security standards.

[0024] In one embodiment of the present invention, the emergency communication vehicle includes high-performance communication equipment and a vehicle-mounted intelligent power management system; the high-performance communication equipment includes a high-power radio, vehicle-mounted satellite communication equipment, and a multi-band antenna; the vehicle-mounted intelligent power management system can automatically allocate power according to the vehicle's operating status and the power consumption requirements of the high-performance communication equipment.

[0025] In one embodiment of the present invention, the switching threshold parameter of the satellite communication backup link system is dynamically set according to the scale of the chemical enterprise, the risk level, and the reliability of the ground network. The satellite terminal equipment has automatic satellite search and signal strength adaptive adjustment functions, and the communication software supports multi-protocol conversion, so as to achieve seamless connection between satellite communication and ground network communication.

[0026] The following are specific embodiments of the present invention, which describe in detail each step from the system deployment stage, emergency drills and practical applications, system maintenance and upgrades, to ensure the efficient operation of the entire system.

[0027] 1. System Deployment Phase:

[0028] First, a comprehensive survey of the chemical enterprise or industrial park is conducted. Based on the production process layout, hazardous area delineation, and distribution of densely populated areas, a detailed deployment plan for Mesh routers is developed. In high-risk areas such as storage tank areas and around large reactors, routers are densely deployed to ensure comprehensive signal coverage. In critical command areas such as office buildings and control rooms, routers are ensured to have high bandwidth and low latency to meet the demands of large-scale data transmission. During installation, routers are protected according to the environmental characteristics of different areas; for example, corrosion-resistant shells are used in areas susceptible to chemical corrosion, and shielding covers are provided in areas with strong electromagnetic interference. Once the emergency communication vehicle is fully equipped, it is parked in a designated standby area, and regular equipment maintenance and drills are conducted to ensure the vehicle is ready for immediate use. Satellite communication terminal equipment is installed in the command center and on some key rescue vehicles. Interconnection and debugging with the ground network are completed, and satellite communication switching threshold parameters are set to ensure the reliability of backup links.

[0029] 2. Emergency Drills and Practical Application:

[0030] During emergency drills, the system is activated, and the mesh routers automatically form an initial network topology. The drill command center issues various commands through the system, verifies communication effectiveness, and collects network performance data, such as transmission latency and packet loss rate, to optimize network configuration based on feedback. In the event of an actual incident, the system responds immediately. Terminals carried by on-site rescue personnel quickly connect to the nearest mesh router, transmitting real-time information such as accident scene footage, casualties, and rescue material needs back to the command center. The command center issues precise dispatch instructions based on this information. If a network node fails, the system automatically optimizes the routing to ensure communication continuity. If a large-scale ground network outage is detected, satellite communication is promptly switched to ensure uninterrupted transmission of critical commands and information collection.

[0031] 3. System maintenance and upgrades:

[0032] Regularly inspect equipment such as Mesh routers, emergency communication vehicles, and satellite communication terminals, checking hardware status and software versions, promptly replacing aging components and updating software patches to ensure stable equipment performance. Based on adjustments to production processes in chemical enterprises and expansion of industrial parks, reassess communication needs, adjust network topology and optimize routing algorithms as needed to improve system adaptability and reliability, and continuously ensure the efficient operation of the emergency communication network.

[0033] This invention discloses a self-organizing and resilient emergency communication network system for chemical enterprises. Through the collaborative design of a self-organizing network infrastructure, a routing optimization module, and a satellite communication backup link system, it deploys wide-bandwidth, high-gain, and highly interference-resistant Mesh routers in key areas such as production workshops and tank areas within chemical industrial parks. Combined with mobile emergency communication vehicles capable of filling gaps, it constructs a multi-hop wireless network. This system utilizes network topology construction algorithms to plan the optimal initial network structure and employs routing optimization strategies to quickly reconstruct communication paths in the event of node failures or strong interference, ensuring continuous data transmission. Simultaneously, a hot-standby satellite communication backup link serves as a safety net, with switching thresholds dynamically set according to the actual situation of the chemical enterprise. Seamless integration with terrestrial networks is achieved through automatic satellite search and multi-protocol conversion. This effectively solves the problems of traditional communication networks relying on fixed base stations, which are prone to failure and have weak anti-interference capabilities. It meets the core requirements of chemical enterprises for highly reliable, resilient, and wide-coverage communication in accident handling and emergency drills, ensuring real-time and uninterrupted transmission of instructions and information feedback between the command center and the rescue site. This provides crucial support for efficient rescue operations and minimizes casualties and property losses caused by accidents.
