[0022] Figure 1is a flowchart of an emergency communication processing method provided by an embodiment of the present application, which is an example and is not limited to the present application. The method can be applied to an emergency communication system, which includes an emergency load device, a plurality of transceiving antennas, a routing management device, a plurality of power supply devices, and a power supply management device. The routing management device is connected to the emergency load device and the plurality of transceiving antennas, and the power supply management device is connected to the plurality of power supply devices, as shown in Figure 1 The method includes the following steps. S101. The routing management device determines a target transmission network of the emergency load device from the networks provided by the plurality of transceiving antennas, and controls the emergency load device to perform data transmission by using the transceiving antenna corresponding to the target transmission network.

[0023] In the embodiment, the emergency communication system can include a plurality of transceiving antennas, and each transceiving antenna can be used to provide a different network. The type of a specific transceiving antenna can be configured according to actual network requirements.

[0024] The target transmission network can be considered as a network to be used by the emergency load device for subsequent data transmission. For example, the target transmission network can be one of the networks provided by the plurality of transceiving antennas.

[0025] In specific applications, unlike the single link backup or manual switching mode used in traditional emergency communication systems, the switching delay is high (usually > 30s), and the bandwidth adaptability is poor. In the embodiment, a double-link adaptive automatic switching logic is designed. The routing management device determines the target transmission network of the emergency load device according to the networks provided by the plurality of transceiving antennas, which can realize second-level perception and switching between different networks. In the embodiment, the specific way of determining the target transmission network is not limited. For example, one of the networks provided by the plurality of transceiving antennas can be randomly selected as the target transmission network of the emergency load device. The target transmission network of the emergency load device can also be determined according to the actual situation of the networks provided by the plurality of transceiving antennas. The target transmission network can also be determined according to the manual intervention of a user, and the like. The embodiment is not limited in this regard.

[0026] As a feasible implementation, the routing management device determines the target transmission network of the emergency load device from the networks provided by the plurality of transceiving antennas, which includes the following steps. The routing management device determines the transmission network corresponding to the network control operation in response to the network control operation of the user. The routing management device determines the target transmission network of the emergency load device from the networks provided by the plurality of transceiving antennas according to the operation type of the network control operation and the transmission network corresponding to the network control operation.

[0027] In a specific application, the emergency communication system can have a manual control switching function, for example, a user can actively select a target transmission network of the emergency load device by performing a network control operation, and the type of the network control operation is not limited, for example, the network control operation can be used to disable or start a network, and accordingly, in the process of determining the target transmission network, the routing management device can first determine the transmission network corresponding to the network control operation; and then determine the target transmission network of the emergency load device from the networks provided by the plurality of transceiving antennas according to the operation type of the network control operation and the transmission network corresponding to the network control operation. For example, when the networks provided by the plurality of transceiving antennas include networks A and B, and the user clicks to disable the network A, then in the case of only one link being turned on, the network B can be determined as the target transmission network of the emergency load device, that is, the network B is the main link by default, and the network A is the backup link, at this time, the backup link does not work. Alternatively, when the networks provided by the plurality of transceiving antennas include networks A and B, and the user clicks to start the network A, then in the case of only one link being turned on, the network A can be determined as the target transmission network of the emergency load device, that is, the network A is the main link by default, and the network B is the backup link, at this time, the backup link does not work.

[0028] In some embodiments, only one link of the main link and the backup link can be used, if the main link is online, that is, the main link has data transmission, the main link can be determined as the target transmission network of the emergency load device, and if the main link has no data transmission, the main link can be offline, at this time, the backup link can be switched to, and similarly, only after the backup link is offline, the main link can be switched to.

[0029] As a feasible implementation manner, the plurality of transceiving antennas at least include a satellite antenna and a base station antenna, the satellite antenna is used to provide a satellite network, and the base station antenna is used to provide a mobile network. The routing management device determines the target transmission network of the emergency load device from the networks provided by the plurality of transceiving antennas, including: the routing management device acquires a first network delay of the satellite network and a second network delay of the mobile network; and the routing management device selects the target transmission network of the emergency load device from the satellite network and the mobile network according to the first network delay and the second network delay.

[0030] The first network delay can be used to represent the time delay accumulated in the process of routing forwarding, physical medium propagation and device processing of the satellite network, and the second network delay can be used to represent the time delay accumulated in the process of routing forwarding, physical medium propagation and device processing of the mobile network.

[0031] In a specific application, the management device can obtain the first network delay of the satellite network and the second network delay of the mobile network through ping packet detection, and then select the target transmission network of the emergency load device from the satellite network and the mobile network according to the specific size of the first network delay and the second network delay. For example, the management device can compare the first network delay and the second network delay to obtain a comparison result. If the comparison result indicates that the first network delay is greater than the second network delay, the mobile network can be selected as the target transmission network of the emergency load device. If the comparison result indicates that the first network delay is less than the second network delay, the satellite network can be selected as the target transmission network of the emergency load device. If the comparison result indicates that the first network delay is equal to the second network delay, the satellite network or the mobile network can be selected as the target transmission network of the emergency load device. On this basis, by automatically selecting the optimal transmission network according to the network delay, the stable operation of the emergency load device in various complex environments can be ensured, and the reliability and adaptability of the emergency communication system are improved.

[0032] Figure 2 is a flowchart of determining a target transmission network provided by an embodiment of the present application. As shown in Figure 2 The management device has a dual-link adaptive switching function, that is, the dual-link backup function can be enabled to make the device have a dual-link switching function. The device mainly judges the network delay by ping packet detection. In this embodiment, the network delay of the satellite network and the 4G / 5G network can be detected by ping packet. At this time, the delay time of the satellite network is greater than 500 ms, and the delay time of the 4G / 5G network is less than 50 ms. Therefore, the 4G / 5G network with a switching delay of less than 50 ms can be preferred, that is, the 4G / 5G network is determined as the target transmission network of the emergency load device, and the internet network is connected to a certain terminal device. If the network time of the 4G / 5G network is greater than 500 ms in the subsequent detection, the satellite network can be switched to instantaneously.

[0033] S102, dynamically determining the target power supply strategy of the emergency load device by the power supply management device according to the current system information of the emergency communication system.

[0034] The current system information can be used to represent the current running state of the emergency communication system. For example, the current system information can include system running data of the emergency communication system at the current time, or system running data of the emergency communication system at multiple sampling periods. The system running data can include relevant running data of each device in the emergency communication system.

[0035] Specifically, the power supply management device can dynamically determine the target power supply strategy of the emergency load device according to the current system information of the emergency communication system. For example, the power supply management device can obtain the current system information of the emergency communication system according to a preset update period, so as to dynamically determine the target power supply strategy of the emergency load device according to the preset update period. The preset update period can be configured according to actual needs.

[0036] Further, the embodiment does not limit the specific means for determining the target power supply strategy. For example, the target power supply strategy of the emergency load device can be directly obtained by inputting the current system information into the power supply model according to the power supply model, or the target power supply strategy of the emergency load device can be determined by a series of calculations on the current system information, and the like. The embodiment does not further expand, as long as the target power supply strategy can be obtained.

[0037] S103, controlling the target power supply device to supply power to the emergency load device based on the target power supply strategy through the power supply management device.

[0038] The target power supply device is determined based on the target power supply strategy. For example, the target power supply strategy can include the type of the target power supply device to be adopted, the load power value specifically borne by the target power supply device, and the priority information between multiple target power supply devices, and the like.

[0039] The emergency communication processing method provided by the embodiment can improve the current power supply efficiency according to the field situation, effectively solve the problem of energy waste, and better adapt to the actual needs of emergency management.

[0040] Figure 3 is a flowchart of an emergency communication processing method provided by another embodiment of the application. In the embodiment, the current system information includes multiple system running data of the emergency communication system collected at a set interval within a preset time length. Each system running data includes at least current load power consumption data of the emergency load device, current business scenario data of multiple transceiving antennas, and current environment data of the emergency communication system. The target power supply strategy of the emergency load device is dynamically determined by the power supply management device according to the current system information of the emergency communication system, which is further optimized as follows: the power supply management device processes the multiple system running data to obtain processed running data; and the power supply management device dynamically generates the target power supply strategy of the emergency load device according to the processed running data and the current energy state of the multiple power supply devices. Figure 3 As shown in the figure, the method includes: S201, determining, by the routing management device, a target transmission network of the emergency load device from a plurality of networks provided by a plurality of transceiving antennas, and controlling the emergency load device to perform data transmission by using a transceiving antenna corresponding to the target transmission network.

[0041] S202, performing mean value processing on the plurality of system running data by the power supply management device to obtain processed running data.

[0042] S203, dynamically generating, by the power supply management device, a target power supply strategy of the emergency load device according to the processed running data and current energy states of the plurality of power supply devices.

[0043] In the embodiment, the current system information can include a plurality of system running data of the emergency communication system collected at a set interval within a preset time length, such as the latest system running data collected at an interval of 10s within one minute, wherein each system running data at least includes current load power consumption data of the emergency load device, current business scenario data of the plurality of transceiving antennas, and current environment data of the emergency communication system.

[0044] Table 1 System running data

[0045] The above table 1 is a system running data provided by the embodiment, which specifically includes load power consumption data, business scenario data, and environment and time data, wherein the load power consumption data can include real-time current, voltage, instantaneous power consumption, and cumulative energy consumption of the alarm camera, 4G skin base station, switch, VOIP phone, satellite antenna, and hard disk video recorder respectively, which can be detected by the intelligent power meter module in the integrated control box and the power consumption monitoring interface provided by the device; the business scenario data can be obtained by the 4G convergence router, the skin base station background, the monitoring platform, and the AI recognition module, and the specific content can include 4G concurrent user number, satellite link bandwidth occupancy rate, video backhaul resolution, voice call duration, and AI recognition trigger number; and the environment and time data can specifically include real-time time, date type, environment light intensity, weather type, temperature, etc.

[0046] In specific application, the power supply management device can directly dynamically generate the target power supply strategy of the emergency load device based on the processed running data and the current energy states of the plurality of power supply devices, or can further process the processed running data and the current energy states of the plurality of power supply devices, and then dynamically generate the target power supply strategy of the emergency load device according to the processing result.

[0047] As a feasible implementation, the power supply management device dynamically generates a target power supply strategy for the emergency load device according to the processed operation data and the current energy state of the plurality of power supply devices, including: The power supply management device performs feature extraction processing on the processed operation data to generate a target feature vector of the emergency communication system; The power supply management device inputs the target feature vector into a load prediction model trained in advance to obtain a target load parameter of the emergency load device after a future set time length, wherein the load prediction model is obtained by training a basic neural network based on training operation data, and the training operation data at least includes training load power consumption data of the emergency load device, training business scenario data of the plurality of transceiving antennas, and training environment data of the emergency communication system. The power supply management device dynamically generates a target power supply strategy for the emergency load device according to the target load parameter and the current energy state of the plurality of power supply devices.

[0048] The training operation data can be a pre-collected training set, which is used to train the basic neural network to obtain the load prediction model, so that the trained load prediction model can be deployed to the power supply management device of the emergency communication system to realize a closed loop of real-time prediction-dynamic decision-power supply adjustment, with a response time of less than 1 second, which meets the real-time demand of the emergency scene.

[0049] For example, the power supply management device can collect the latest system operation data every 10 seconds within 1 minute, including current load power consumption data, current business scenario data, and current environment data, and then perform mean value processing on the plurality of system operation data to obtain processed operation data. The processed operation data is subjected to feature extraction processing to obtain an 8-dimensional target feature vector. On this basis, a curve graph is formed by capturing the system operation rule through short-term quantitative data, which provides multi-dimensional input for the load prediction model and data support for subsequent dynamic power supply decision. Then, the generated 8-dimensional target feature vector can be input into the load prediction model trained in advance, so as to generate a future 15-minute load prediction curve (i.e., a target load parameter) every 1 minute, and mark a high confidence interval (error 5%). The future 15-minute load prediction curve is considered as a predicted load demand, such as daily stable load demand state, sudden communication load demand state, and extreme disaster load demand state within the next 15 minutes.

[0050] Finally, based on the predicted load demand and the current energy state of each power supply link (such as whether the mains power is available, the real-time power generation of photovoltaic, the remaining power of lithium battery, and whether the generator is started), the optimal target power supply strategy is selected from the pre-stored power supply strategies through a priority scheduling algorithm.

[0051] (1) For scenario 1: daily stable load (e.g. night surveillance camera power consumption 90W), current energy status includes mains available, photovoltaic stopped generating (night), lithium battery remaining capacity 80%, the generated target power supply strategy can include preferentially allocating mains power supply (low cost, no energy consumption), lithium battery standby; if the mains is temporarily interrupted (e.g. power grid fluctuation), switch to lithium battery power supply within 0.5 seconds (no instantaneous interruption), while monitoring the lithium battery capacity (trigger generator start warning when below 20%).

[0052] (2) For scenario 2: burst communication load (e.g. predicted load increases from 100W to 180W for 30 minutes), current energy status includes mains available, photovoltaic power generation 120W (daytime sunny), lithium battery remaining capacity 60%, the generated target power supply strategy can be to use mains + photovoltaic cooperative power supply, specifically including mains bearing 100W basic load, photovoltaic bearing 80W burst increment, avoiding lithium battery consumption; if the photovoltaic power generation fluctuates (e.g. cloud cover decreases to 60W), automatically call lithium battery to supplement 20W, to ensure that the total power supply meets the demand of 180W.

[0053] (3) For scenario 3: extreme disaster load (e.g. mains interruption, heavy rain, predicted load 150W for 12 hours), current energy status includes mains interruption, photovoltaic power generation <30W (heavy rain), lithium battery remaining capacity 90%, generator started, the generated target power supply strategy can be to use lithium battery + generator cooperative power supply, specifically including preferentially using lithium battery power supply for the first 6 hours to reduce generator noise and oil consumption, when the lithium battery capacity drops to 30%, automatically start the generator (seamless switching, no instantaneous interruption), the generator bears 120W load, the lithium battery supplements 30W, to ensure 12 hours of continuous power supply; at the same time, it can continue to predict the future 6 hours of weather through AI, if it is predicted to be sunny, it can adjust to photovoltaic + lithium battery power supply strategy in advance, and the generator is turned off.

[0054] In some embodiments, the update period of the pre-stored power supply strategy can be 30 days.

[0055] S204, through the power supply management device, control the target power supply device in the plurality of power supply devices to supply power to the emergency load device based on the target power supply strategy.

[0056] The emergency communication processing method provided by the embodiment breaks through the traditional power supply mode of simple addition of photovoltaic and lithium batteries, provides multi-source access of commercial power, photovoltaic, lithium battery and generator, predicts load demand (such as stable power consumption of night vigilance camera and sudden increase of communication business power consumption) through an AI algorithm, can realize dynamic allocation of power supply link, converts experience-driven power supply allocation into data-driven accurate decision, thereby avoiding system downtime caused by insufficient power supply and reducing energy waste (such as idling of generator and excessive consumption of lithium battery) in an emergency scene, and providing core technical support for 7x24-hour stable operation of an emergency communication system.

[0057] The emergency communication processing method corresponding to the above embodiment, Figure 4 is a structural block diagram of an emergency communication system provided by an embodiment of the present application.

[0063] Figure 5 is a structural block diagram of another emergency communication system provided by an embodiment of the present application, referring to Figure 5 The emergency communication system includes transceiving antennas, a monitoring video, an integrated control box, a plurality of power supply devices, a voice device, and a lightning protection system (not shown in the figure), wherein the transceiving antennas can be composed of a 0.6-meter satellite communication antenna, a base station barrel antenna, a base station GPS antenna, a 4G antenna, etc.; the monitoring video can be a warning camera; the integrated control box can include a TP-LINK industrial switch, a 4G convergence router (i.e., a routing management device), a skin base station (i.e., a main base station), a hard disk video recorder, a codec, a switching power supply (i.e., a power supply management device), a power supply control switch, a DC12V to DC24V, a DC12V to DC12V, a DC5V to DC5V 3-group voltage stabilizing power supply module, etc.; the plurality of power supply devices can include an external photovoltaic panel, a mains electricity, a generator, and a lithium battery; the voice device can be an external VOIP telephone; and the lightning protection system includes a lightning rod and a grounding needle.

[0064] In a specific application, the satellite communication antenna can provide a sub-Asia 6D high-throughput satellite network, and the 4G antenna can provide a 4G network signal. The satellite network and the 4G network pass through a 4G convergence router, and the 4G convergence router automatically selects an online network service (such as selecting a 4G network signal), so that the 4G network signal can be used to provide network services for the warning camera, the skin base station, and the codec, voice service, and meteorological monitoring service. At the same time, the 4G network signal can be used to return the video of the warning camera to the monitoring platform to realize real-time monitoring of the system. If the 4G network signal is interrupted, the convergence router can select to switch to the satellite network, and use the satellite network to provide network services for the warning camera, the skin base station, and the encoder. Among them, the satellite link supports a sub-Asia 6D high-throughput satellite, and the uplink / downlink bandwidth is ≥5 Mbps / 10 Mbps, which meets the demand of high-definition video return and voice communication; the automatic switching time of the main and standby links (4G network and satellite network) is ≤5 s, which can ensure uninterrupted communication.

[0065] In addition, the emergency communication system can automatically network when powered on, and can be powered by four modes of city power, photovoltaic, lithium battery and generator. Among them, the combination of photovoltaic and lithium battery realizes the "city power supplement + emergency energy storage" double mode, the lithium battery endurance is ≥12 hours, and after connecting the generator, it can provide power for 24 hours without interruption. Three groups of voltage stabilizing power modules (DC12V to DC24V / 12V / 5V) can adapt to the power supply needs of different equipment, and the power supply switching has no instantaneous interruption. For example, the emergency communication system can preferentially use 4G traffic and city power on a daily basis, and low-power equipment (such as a switch with a power consumption of only 1.63W) to reduce operating costs; solar panels supplement lithium batteries to reduce dependence on city power and are suitable for long-term deployment in remote areas.

[0066] For example, in a specific embodiment, after an earthquake or flood causes a "three-break" situation, the local village can quickly restore communication through the emergency communication system of the embodiment, such as the system can automatically switch to solar power and simultaneously start the 4G / satellite dual-link intelligent switching function, select the best communication link according to the on-site network signal condition, and realize real-time video call and data transmission with the command center; during the continuous rescue process, the power supply module can work cooperatively through the photovoltaic panel and the lithium battery to ensure the stable operation of the system for more than 12 hours.

[0067] The emergency communication system also supports remote monitoring of all equipment modules (such as power, signal, fault state), and the background can issue control instructions in real time, such as the emergency load equipment has a remote switch restart function, and the emergency communication system can realize remote control of the emergency load equipment; the skin base station supports 32 concurrent users and 96 connected users, and the VOIP phone supports white list / black list management, which is suitable for grassroots emergency command scenarios and realizes intelligent management of the system.

[0068] In some embodiments, in order to meet the rapid deployment requirements in the "circuit breaking" scenario, the emergency communication system of the present embodiment also innovatively adopts a modular design, which is specifically designed as follows: 1. The pole height is <3m, the ground cage is buried to a depth of 70cm, and the installation occupies an area of only 80cmx80cmx80cm, which is 98% smaller than the traditional emergency communication vehicle (occupies an area of >5m2), and a team of 2 people can complete the assembly within 30 minutes; 2. The control box integrates heat dissipation, insect prevention, and rain prevention design, the satellite communication antenna cable adopts a bent pipe waterproof structure, and the overall protection reaches the IP65 standard, which can stably operate in an environment of 20℃-60℃, solving the problem of equipment damage in harsh environments in remote areas; 3. The wind resistance reaches level 10, which is verified by wind tunnel test (simulated wind speed 25m / s for 6 hours, no structural damage to the equipment), which is better than similar products in the industry (generally 8-9 wind resistance).

[0069] In summary, the emergency communication system provided in the present embodiment combines satellite communication technology, wind-solar complementary technology, video monitoring technology, and AI intelligent identification technology, mainly solves the environmental monitoring in areas without signal and the communication and emergency management needs of grassroots emergency units in the "three breaks" (power failure, network failure, circuit breaking) situation in response to sudden disaster events, and can provide video pictures, WiFi services and 4G services in emergency communication to ensure uninterrupted communication in disaster areas, such as grassroots emergency personnel can not be interrupted through mobile phone access to satellite network, timely and quickly report the on-site situation, and realize uninterrupted command and management. At the same time, the base station realizes the self-recognition function of key area defense and personnel movement, and its main functions include the following: Firstly, the emergency communication system provided in the present embodiment adopts 4G / satellite dual-link intelligent switching technology (switching time ≤10s), both the main and standby links support uplink ≥5Mbps and downlink ≥10Mbps bandwidth, and the satellite link is based on Asia Pacific 6D high-throughput satellite, which can still ensure smooth communication even in extreme weather such as heavy rain, solving the problem of communication failure after the interruption of the single network in the existing system, and enhancing the communication continuity and stability.

[0070] Secondly, the emergency communication system provided in the present embodiment adds a photovoltaic panel (180W, efficiency ≥20%), which supplements the lithium battery (150AH, endurance ≥12 hours), and combines the multi-mode redundant switching of city power / lithium battery / generator (instantaneous switching without power failure), to realize 7x24 hours continuous power supply. At the same time, the design of low-power components (total power consumption ≤150W) further reduces energy consumption, solves the problem of insufficient endurance of the existing system in the "power failure" scenario, and optimizes the power supply reliability and endurance of the system.

[0071] Again, the modular design of the emergency communication system provided by the embodiment can support rapid assembly (≤30 min) on site, the construction occupies an area of only 80 cm x 80 cm, and is suitable for the rapid deployment requirements of the grassroots emergency units in the "circuit breaking" scene, the equipment operating temperature covers -20°C~60°C, the protection level is IP65, and the equipment can stably operate in complex environments such as remote areas and disaster sites, so the site selection is free and is not limited by infrastructure, and the deployment efficiency and adaptability are further improved.

[0072] Then, the black light warning camera (0.001 Lux minimum illumination, supporting night vision / mist penetration) in the emergency communication system provided by the embodiment can intelligently identify personnel movement and the like, automatically capture and transmit real-time images to the monitoring platform, and realize all-weather situation monitoring; remote monitoring of all equipment (switch restart, parameter configuration) and 24-hour background fault handling solve the problems of "monitoring blind area" in the existing system in the signal-free area and the lack of remote management, and strengthen the monitoring and management capabilities of the system. For example, by comprehensively using posture sensing, infrared intrusion, visible light image sensing, and other composite sensing and artificial intelligence technologies, vehicles, personnel, animals, and the like can be accurately identified, and by using NB-IoT, 4G, and satellite base stations, on-site data can be returned, and warning information can be automatically reported. At the same time, for special areas, the surrounding area can automatically capture and report warning information, and the information can be automatically pushed to the management platform or the mobile terminal, solving the problem of manned and real-time viewing, realizing the effect of no power supply, long-term power supply, and no manual attendance, and providing reliable protection for environmental protection and safety in special areas.

[0073] Finally, the emergency communication system provided by the embodiment strictly follows the standards of the communication guarantee specification, and ensures the legality and reliability in the emergency scene. At the same time, by integrating a lightning protection system (lightning rod, grounding pin, grounding resistance ≤4Ω), a 10-level wind resistance design (a vertical rod structure can resist 10-level wind), and a theft prevention mechanism (monitoring warning + reinforced installation), the problem that the existing system is easily damaged by nature or man in outdoor harsh environments is solved.

[0074] Therefore, the application field of the emergency communication system provided by the embodiment is wide, and the emergency communication system can be applied to natural disaster emergency communication, such as in the "three breaks" scene of earthquake, flood, and typhoon, to provide 4G / WiFi coverage, VOIP voice communication, and video return for rescue teams, and support remote command of superior units.

[0075] The emergency communication system can also be applied to daily monitoring and communication in remote areas, such as signal-free areas in mountainous areas, pastoral areas, and forests, and can realize forest and grass fire prevention and wild animal monitoring through the warning camera, and provide basic communication services for local residents through the 4G skin base station.

[0076] The emergency communication system can also be applied to temporary guarantee in special scenarios, such as providing an emergency communication backup for large-scale activities (such as outdoor events, temple fairs), and providing regional communication guarantee for sudden public events (such as epidemic control).

[0077] The emergency communication system can also be used for industry special monitoring, including reservoir and river water level monitoring and remote early warning in the water conservancy field; in the meteorological field, it can realize real-time data return of temperature, humidity, wind power and the like in remote areas in combination with meteorological sensors; and in the transportation field, it can provide road condition monitoring and emergency communication for mountainous roads and railways.
