Description

Technical Field

[0001] The present invention relates to the technical field of deep-sea manned submersible application, and in particular to an automatic detection networking system for underwater operation status of a manned submersible. Background Art

[0002] The deep sea is rich in resources, and the development and use of deep-sea manned submersibles is a marine project of great strategic significance. Manned submersibles are equipped with electronic devices, mechanical equipment, operating tools and other equipment. Under the operation of professionals, they reach the deep sea and the seabed to carry out scientific investigations, resource exploration, environmental investigations, search and rescue of wrecked ships and salvage of objects that have fallen into the sea. This is the development trend of the application of manned submersible technology. Deep-sea manned submersibles have to withstand huge water pressure, fight against dangerous unknown ocean currents, adapt to harsh working environments such as no natural light, and directly face various high risks.

[0003] Conventional radio waves cannot be transmitted in deep sea areas, and existing technologies are unable to establish reliable, real-time communication links with large data volumes.

[0004] In the existing technology, the detection of the working status of each manned submersible belongs to different systems, and the status information of a single or even multiple manned submersibles in underwater operation has not been organically integrated into a unified and comprehensive information system publishing platform.

[0005] Manned submersibles have a complex technical structure and can be equipped with different functional equipment to perform corresponding diving tasks according to different tasks. Existing technology can only rely on manpower to check each device one by one and comprehensively detect the instruments, equipment and crew carried by manned submersibles. Not only does it consume a lot of energy and time, especially when manned submersibles are operating in deep sea areas, because the team members on the mother ship cannot immediately obtain the comprehensive status information of the submersible's underwater operations, it is difficult to timely discover changes in the working conditions of various systems, conduct risk analysis, and propose emergency measures.

[0006] Under the existing technical conditions, command personnel and operation and maintenance personnel are all dispersed and assigned to the surface mother ships of each submersible to stand by, and far away from the manned submersibles in deep diving. Due to the limitations of communication conditions, it is impossible to monitor and obtain the real-time status of the manned submersibles and crew in deep diving, and provide more useful suggestions.

[0007] The current situation is that when a single manned submersible is diving deep or multiple manned submersibles are diving deep in different sea areas, the comprehensive real-time monitoring of the status of equipment and personnel cannot be implemented under the existing technical conditions, and the technicians of each component system of the submersible cannot obtain real-time working condition information in time. Limited by the existing technical conditions, the deep diving stage, which is the most valuable and risky in the manned submersible diving mission, cannot carry out efficient team collaboration because a full-range real-time communication system has not yet been established. To ensure the normalization of deep diving and safe operation of manned submersibles, it should be based on a comprehensive and real-time grasp of the status of manned submersibles and crew during deep diving and maintaining close communication. Summary of the invention

[0008] In view of the shortcomings in the above-mentioned existing production technology, the applicant provides an automatic detection networking system for the underwater operating status of a manned submersible, which can conveniently and automatically detect, collect, process and transmit the operating information of multiple manned submersibles, and realize data fusion and information sharing.

[0009] The technical solution adopted by the present invention is as follows:

[0010] The invention discloses an automatic detection networking system for underwater operation status of a manned submersible, which establishes a real-time status detection system covering the entire underwater operation mission profile of the manned submersible. Based on computer network communication technology, the network terminals of multiple manned submersible instruments, equipment and personnel in underwater operation are combined into a systematic communication network. Personnel in various positions use the network terminals in their hands to understand and obtain the real-time status of the manned submersibles and their occupants in the corresponding deep dive, and strengthen the prediction and disposal of safety risks. The overall technical framework is: a short-range communication network based on the manned submersible is established under the surface of the water, and a long-range communication network based on the mother ship is established on the surface of the water, and an underwater data communication link is established between the manned submersible and the mother ship to form a complete communication network. Personnel in various positions of each manned submersible in underwater operation access the network with a network terminal and use Ethernet technology to form a network. Redundant interfaces are reserved for the short-range communication network and the long-range communication network, which can be used as a backup and for network expansion.

[0011] Its further technical solution is:

[0012] The short-range communication network is composed of a network switch, a manned submersible computer, and multiple working condition detection units. The manned submersible computer is interconnected with the network switch. The control panel and operating handle of the manned submersible are directly connected as peripheral devices of the manned submersible computer. They are connected to the underwater data communication link through an acoustic transceiver to upload and download information. The long-range communication network is a communication network established on the water surface through Ethernet technology, including a mother ship network server, a mother ship fixed computer, a mother ship mobile terminal, a space-based communication satellite, a shore-based command center, and a shore-based mobile terminal. The mother ship mobile terminal is a tablet computer or smart phone that accesses the manned submersible underwater operation global communication network through the wireless communication local area network established on the mother ship. The shore-based mobile terminal and the remote fixed terminal access the fixed terminal, tablet computer, and smart phone of the manned submersible underwater operation global communication network through space-based communication satellites.

[0013] The acoustic transceiver uses two channels: underwater acoustic transmission and underwater acoustic reception. The underwater acoustic transmission channel is the channel for manned submersibles to upload information. When uploading information, the electrical signal of the network switch is transmitted to the acoustic transducer of the manned submersible, converted into an acoustic signal and then transmitted in a direction; the underwater acoustic reception channel is the channel for manned submersibles to download information from the Internet. When downloading information, the received acoustic signal is converted into a weak electrical signal through the transducer, and then transmitted to the network switch after noise reduction and gain amplification.

[0014] Network switches transmit information in the form of electrical signals over the manned submersible's short-range network.

[0015] The manned submersible computer is the intelligent unit of the manned submersible short-range network. It stores the operating data, work logs and troubleshooting of the manned submersible and its crew. It operates all information related to the submersible's deep diving operations, and is equipped with manned submersible control software, information processing software, and network communication management and control software. The information processing software processes the operating information detected by each operating condition detection unit and generates charts and reports. It is equipped with a display terminal to display the operating information that needs to be displayed for the manned submersible and its onboard instruments and equipment. It supports multi-tasking operations and uses split-screen or single-screen highlighting to display the equipment operating conditions of each system when the manned submersible is operating underwater.

[0016] The operating condition detection unit is a system setting for manned submersibles during underwater operations, including operating condition detection modules, sensors, actuators, monitoring equipment, and unit network interfaces. The number of each operating condition detection unit is determined by the technical composition of the manned submersible, the content of the deep diving mission, and the characteristics of the onboard instruments and equipment.

[0017] The working condition detection module is classified and designed to detect observation data, communication data and detection data; the capacity of various interfaces adopts redundant design and meets the needs of expanding the detection and monitoring objects; the working condition detection module adopts universal, serialized and combined design to make universal parts or standard parts, which facilitates each manned submersible to perform tasks of different nature, maintenance and expanded detection needs.

[0018] The mother ship network server is the intelligent unit for the entire manned submersible diving operation. It stores the operating condition data of each system of the manned submersible in a classified manner, transmits information with the manned submersible through the network, and transmits information with each network access terminal, including operating information and data related to the underwater operation of the submersible. It is equipped with the manned submersible underwater operation operation and management software, information collection and processing software, and network communication control software. Among them, the information collection and processing software is dedicated to the storage and processing of various working condition information, and generates charts and reports; it is connected to the display screen of the mother ship command cabin to display the information that each system needs to display when the manned submersible is operating underwater, supports multi-task operation, and uses split-screen or single-screen highlighting to display the equipment working conditions of each system when the manned submersible is operating underwater;

[0019] The network terminals are mobile terminals and fixed computers used by command personnel, operation and maintenance personnel and technical team support personnel on the mother ship, including networked mobile devices accessed through space-based communication satellites and fixed computers used by remote technical experts, visitors and other personnel at the shore-based command center; among them, the shore-based command center has the function of realizing data fusion and information sharing of multiple manned submersibles. Personnel on the manned submersible remote communication network access the corresponding mother ship network server through the network terminals they hold according to the different allocated permissions during the diving operation of the corresponding submersible, obtain real-time operating information of the corresponding manned submersible diving operation, and conduct online communication and interaction.

[0020] It also includes an escort submersible signal relay station, which is a sound wave signal enhancement and transmitting device. Through the underwater signal relay station, the received sound wave signal is amplified and enhanced and then transmitted in a direction. It can refract the propagation direction of the sound wave signal, bypass obstacles that block the transmission of sound waves, and support the transmission of sound wave signals with large data flow.

[0021] The method of establishing the underwater data communication link between the manned submersible and the mother ship is determined by the environmental conditions when the manned submersible arrives at the sea area. If a small-depth diving mission is performed and there is no obstruction between the mother ship and the manned submersible in a straight-line distance, the electronic pod configured on the mother ship can directly establish a data communication link with the signal transceiver of the manned submersible. If a deep-depth diving mission is performed, it is necessary to deploy an escort submersible equipped with an underwater signal relay station to establish a data communication link; if there is an obstruction between the mother ship and the manned submersible in a straight-line distance, two or more escort submersibles equipped with underwater signal relay stations can be deployed to amplify and forward the hydroacoustic signal; the mother ship, escort submersible and manned submersible carry out mobile joint operations to ensure that the established underwater data communication link transmits data stably and smoothly, and realizes comprehensive, systematic and automatic real-time detection of the working dynamics of the manned submersible.

[0022] The beneficial effects of the present invention are as follows:

[0023] The present invention has a compact and reasonable structure and is easy to operate. It effectively solves the problem of real-time detection of the working conditions of each component system when a manned submersible performs a diving mission, establishes a real-time status detection system covering the entire underwater operation mission profile of the manned submersible, and solves the problem of interconnection and intercommunication between personnel and equipment when a manned submersible performs a deep diving mission.

[0024] The method for establishing an underwater data communication link between a manned submersible and a mother ship in the present invention solves the problem of long-distance communication in deep-sea areas, and also solves the problem of communication under obstructions and obstacles in underwater communication. It realizes the establishment of communication links in complex deep-sea areas, and the global networking of the surface and underwater when a manned submersible is operating underwater.

[0025] In the present invention, the full-area two-way communication network of manned submersibles realizes information sharing and data fusion of multiple manned submersibles, so that when the manned submersibles are operating underwater, personnel in various positions can share various working data of the manned submersibles in real time without being restricted by geographical conditions, which greatly improves the team's command ability, mission support ability and emergency rescue ability.

[0026] In the present invention, the personnel in each post who are online can always pay attention to the working status of each component system and, when necessary, conduct technical exchanges with the submersible operator who performs the diving mission, thereby avoiding further deterioration of abnormal phenomena.

[0027] In the present invention, the automatic acquisition, automatic processing and automatic distribution of the working condition information of each component system of the manned submersible underwater operation are realized, and there is no need for manual transcription and transmission of information, which greatly simplifies the work process of personnel in various positions and reduces the work intensity; it completely eliminates the phenomenon of miscopying and mistransmission of information, and avoids the occurrence of man-made accidents to a limited extent.

[0028] In the present invention, the detected working condition information is fed back to the control system in a timely manner, and cooperates with the control system to maintain the best working state. When uncontrollable abnormal phenomena occur, the alarm is promptly issued and the emergency plan is activated to avoid the occurrence of safety accidents caused by further deterioration of the situation.

[0029] In the present invention, the status information and related sea area information of multiple manned submersibles during underwater operations accumulated in the shore-based command center over the years can be gradually formed into a manned submersible operation data information database covering the global waters after classification and analysis, so as to further improve the safety of subsequent submersible operations and enhance the ability of risk prediction and emergency response.

[0035] The specific implementation of the present invention will be described below in conjunction with the accompanying drawings.

[0036] like Figure 1-Figure 5 As shown, the automatic detection networking system for the underwater operation status of a manned submersible of the present embodiment establishes a real-time status detection system covering the entire underwater operation mission profile of a manned submersible. Based on computer network communication technology, the network terminals of multiple manned submersible instruments, equipment, and personnel in underwater operation are combined into a systematic communication network. Personnel in various positions use the network terminals in their hands to understand and obtain the real-time status of the manned submersible and its occupants in the corresponding deep dive, and strengthen the prediction and disposal of safety risks. The overall technical framework is: a short-range communication network based on the manned submersible is established under the water surface, and a long-range communication network based on the mother ship is established on the surface of the water. An underwater data communication link is established between the manned submersible and the mother ship to form a complete communication network. Personnel in various positions of each manned submersible operating underwater access the network with a network terminal and use Ethernet technology to form a network. Redundant interfaces are reserved for the short-range communication network and the long-range communication network, which can be used as a backup and for network expansion.

[0037] The short-range communication network is composed of a network switch, a manned submersible computer, and multiple working condition detection units. The manned submersible computer is interconnected with the network switch. The control panel and operating handle of the manned submersible are directly connected as peripheral devices of the manned submersible computer. They are connected to the underwater data communication link through an acoustic transceiver to upload and download information. The long-range communication network is a communication network established on the water surface through Ethernet technology, including a mother ship network server, a mother ship fixed computer, a mother ship mobile terminal, a space-based communication satellite, a shore-based command center, and a shore-based mobile terminal. The mother ship mobile terminal is a tablet computer or smart phone that accesses the manned submersible underwater operation global communication network through the wireless communication local area network established on the mother ship. The shore-based mobile terminal and the remote fixed terminal access the fixed terminal, tablet computer, and smart phone of the manned submersible underwater operation global communication network through space-based communication satellites.

[0038] The acoustic transceiver uses two channels: underwater acoustic transmission and underwater acoustic reception. The underwater acoustic transmission channel is the channel for manned submersibles to upload information. When uploading information, the electrical signal of the network switch is transmitted to the acoustic transducer of the manned submersible, converted into an acoustic signal and then transmitted in a direction; the underwater acoustic reception channel is the channel for manned submersibles to download information from the Internet. When downloading information, the received acoustic signal is converted into a weak electrical signal through the transducer, and then transmitted to the network switch after noise reduction and gain amplification.

[0039] Network switches transmit information in the form of electrical signals over the manned submersible's short-range network.

[0040] The manned submersible computer is the intelligent unit of the manned submersible short-range network. It stores the operating data, work logs and troubleshooting of the manned submersible and its crew. It operates all information related to the submersible's deep diving operations, and is equipped with manned submersible control software, information processing software, and network communication management and control software. The information processing software processes the operating information detected by each operating condition detection unit and generates charts and reports. It is equipped with a display terminal to display the operating information that needs to be displayed for the manned submersible and its onboard instruments and equipment. It supports multi-tasking operations and uses split-screen or single-screen highlighting to display the equipment operating conditions of each system when the manned submersible is operating underwater.

[0041] The operating condition detection unit is a system setting for manned submersibles during underwater operations, including operating condition detection modules, sensors, actuators, monitoring equipment, and unit network interfaces. The number of each operating condition detection unit is determined by the technical composition of the manned submersible, the content of the deep diving mission, and the characteristics of the onboard instruments and equipment.

[0042] The working condition detection module is classified and designed to detect observation data, communication data and detection data; the capacity of various interfaces adopts redundant design and meets the needs of expanding the detection and monitoring objects; the working condition detection module adopts universal, serialized and combined design to make universal parts or standard parts, which facilitates each manned submersible to perform tasks of different nature, maintenance and expanded detection needs.

[0043] The mother ship network server is the intelligent unit for the entire manned submersible diving operation. It stores the operating condition data of each system of the manned submersible in a classified manner, transmits information with the manned submersible through the network, and transmits information with each network access terminal, including operating information and data related to the underwater operation of the submersible. It is equipped with the manned submersible underwater operation operation and management software, information collection and processing software, and network communication control software. Among them, the information collection and processing software is dedicated to the storage and processing of various working condition information, and generates charts and reports; it is connected to the display screen of the mother ship command cabin to display the information that each system needs to display when the manned submersible is operating underwater, supports multi-task operation, and uses split-screen or single-screen highlighting to display the equipment working conditions of each system when the manned submersible is operating underwater;

[0044] The network terminals are mobile terminals and fixed computers used by command personnel, operation and maintenance personnel and technical team support personnel on the mother ship, including networked mobile devices accessed through space-based communication satellites and fixed computers used by remote technical experts, visitors and other personnel at the shore-based command center; among them, the shore-based command center has the function of realizing data fusion and information sharing of multiple manned submersibles. Personnel on the manned submersible remote communication network access the corresponding mother ship network server through the network terminals they hold according to the different allocated permissions during the diving operation of the corresponding submersible, obtain real-time operating information of the corresponding manned submersible diving operation, and conduct online communication and interaction.

[0045] The remote communication network uses the mother ship as a platform and Ethernet technology to build a communication network, which is mainly composed of the mother ship network server and various network terminals. The terminals that access the network through space-based communication satellites are not restricted by the location of the terminals.

[0046] It also includes an escort submersible signal relay station, which is a sound wave signal enhancement and transmitting device. Through the underwater signal relay station, the received sound wave signal is amplified and enhanced and then transmitted in a direction. It can refract the propagation direction of the sound wave signal, bypass obstacles that block the transmission of sound waves, and support the transmission of sound wave signals with large data flow.

[0047] The method of establishing the underwater data communication link between the manned submersible and the mother ship is determined by the environmental conditions when the manned submersible arrives at the sea area. If a small-depth diving mission is performed and there is no obstruction between the mother ship and the manned submersible in a straight-line distance, the electronic pod configured on the mother ship can directly establish a data communication link with the signal transceiver of the manned submersible. If a deep-depth diving mission is performed, it is necessary to deploy an escort submersible equipped with an underwater signal relay station to establish a data communication link; if there is an obstruction between the mother ship and the manned submersible in a straight-line distance, two or more escort submersibles equipped with underwater signal relay stations can be deployed to amplify and forward the hydroacoustic signal; the mother ship, escort submersible and manned submersible carry out mobile joint operations to ensure that the established underwater data communication link transmits data stably and smoothly, and realizes comprehensive, systematic and automatic real-time detection of the working dynamics of the manned submersible.

[0048] The overall technical framework of the present invention is as follows Figure 1 The specific structure includes: a mother ship, a communication satellite, a shore-based mobile terminal and a shore-based command center on the surface; an electronic pod on the mother ship, an escort submersible and a manned submersible under the surface. The electronic pod is deployed by the mother ship, and the deployment depth can be adjusted.

[0049] The underwater data communication link established between the manned submersible and the mother ship is dedicated to the interconnection between the manned submersible short-range communication network and the manned submersible long-range communication network. It includes the electronic pod configured on the mother ship, the underwater signal relay station carried by the escort submersible, and the signal transceiver of the manned submersible.

[0050] The mother ship electronic pod is a hydroacoustic signal transceiver that is laid below the water surface by the mother ship through cables. The electrical signal and the acoustic signal are converted to each other through the transducer. When receiving information uploaded by the manned submersible, the acoustic signal is converted into an electrical signal; when sending information to the manned submersible, the electrical signal is converted into an acoustic signal and the electronic pod is launched.

[0051] The present invention provides a global communication network for underwater operations of manned submersibles, which can support information access and sharing of multiple manned submersibles. In this embodiment, only three manned submersibles are used for illustration. The network composition is as follows: Figure 2 As shown, it includes a manned submersible long-range communication network on the water surface, an underwater data communication link under the water surface, and a manned submersible short-range communication network.

[0052] like Figure 2As shown in the figure, the remote communication network of manned submersibles is a communication network established on the water surface through Ethernet technology, including mother ship network servers, mother ship stationary computers, mother ship mobile terminals, space-based communication satellites, shore-based command centers, and shore-based mobile terminals. The mother ship mobile terminals are tablet computers, smart phones, etc. that access the manned submersible underwater operation global communication network through the wireless communication local area network (WIFI) established on the mother ship. The shore-based mobile terminals and remote stationary terminals access the fixed terminals, tablet computers, smart phones, etc. of the manned submersible underwater operation global communication network through space-based communication satellites.

[0053] like Figure 2 As shown in the figure, the manned submersible short-range communication network is a communication network formed inside the manned submersible through Ethernet technology, including a network switch, a manned submersible computer, an in-cabin working condition detection unit, an out-cabin working condition detection unit, and a standby working condition detection unit. The wired Ethernet technology is used to form an interconnected and interoperable communication network. The manned submersible computer is a modified industrial control computer. The control panel and operating handle of the manned submersible are directly connected to the manned submersible computer as external devices of the manned submersible computer.

[0054] like Figure 1 and Figure 2 As shown, the underwater data communication link includes an electronic pod deployed in the water by a mother ship through cables, an escort submersible equipped with a signal relay station, and an acoustic transceiver integrated on the manned submersible. The electronic pod is connected to the mother ship network server through optical cables and electrical cables. The underwater data communication link adopts underwater acoustic wave communication technology. When the manned submersible communicates with the mother ship in a two-way manner, the hydroacoustic signal is relayed by the escort submersible. It not only solves the problem that wired Ethernet technology limits the mobility of deep-diving manned submersibles, but also overcomes the difficulties of too short underwater acoustic wave communication distance and limited transmission data volume. As an underwater acoustic signal relay station, the escort submersible doubles the underwater acoustic wave communication distance and data volume, and can also adjust the transmission direction of the hydroacoustic signal, such as bypassing possible obstacles such as icebergs to transmit information.

[0055] like Figure 1As shown in the figure, in actual application, the establishment of underwater data communication link should be determined according to the communication conditions of the manned submersible arrival area, the diving depth, the deep-sea environment, and whether there are obstacles between the mother ship and the manned submersible in a straight line. If the communication conditions in the arrival area are good, the diving depth is not large, the deep-sea environment is good, and there are no obstacles between the mother ship and the manned submersible to block the transmission of hydroacoustic signals, there is no need to deploy an escort submersible for hydroacoustic signal relay. The electronic pod directly establishes communication with the manned submersible to build an underwater data communication link; if the communication conditions in the deep diving area are not good, the diving depth is large, the deep-sea environment is harsh, and there are obstacles between the mother ship and the manned submersible to block the transmission of hydroacoustic signals, it is necessary to deploy an escort submersible for hydroacoustic signal relay and build an underwater data communication link. If one escort submersible equipped with a signal relay station is not enough to ensure stable and smooth communication of the underwater data communication link, two or more escort submersibles need to be deployed for hydroacoustic signal relay. Mobile joint operations between the mother ship, escort submersible and manned submersible can ensure that the established underwater data communication link can transmit data stably and smoothly, and realize comprehensive, systematic and automatic real-time detection of the working dynamics of the manned submersible.

[0056] like Figure 1 , Figure 2 As shown in the figure, the underwater data communication link connects the manned submersible remote communication network on the surface with the manned submersible short-range communication network underwater, and builds a manned submersible underwater operation global communication network. Using this network, manned submersibles performing deep diving missions can upload real-time working conditions to the mother ship network server, which is then distributed in real time to various terminals on the manned submersible remote communication network. Command personnel, operation and maintenance personnel, and technical team support personnel on the mother ship use mobile terminals and fixed computers, including remote technical experts and visitors at the shore-based command center accessed through space-based communication satellites. They use their own Internet terminals to access the network, timely understand and grasp the real-time working conditions of manned submersibles, and solve the problem of real-time sharing of manned submersible and personnel working conditions information during deep diving; the mother ship mobile terminals and various terminals accessing the network through space-based satellites are completely free from location and geographical restrictions, and can support the establishment of a cross-regional manned submersible technical support team, which greatly improves the team's command ability, mission support ability, and emergency rescue ability. When each manned submersible is operating underwater, the professionals of each component system closely monitor the changes in the operating conditions of the equipment / devices under their charge through their respective network terminals. When necessary, they conduct technical exchanges with the submersible operators performing the diving mission, thus avoiding further deterioration of abnormal phenomena.

[0057] like Figure 1 , Figure 2 and Figure 3As shown, the mother ship's electronic pod includes cables, optical cables and cable interfaces, acoustic transducers, acoustic transmitters, acoustic receivers and acoustic transceiver terminals. One end of the cable is fixed to the mother ship, and the other end is fixed to the electronic pod. The cable uses a twisted cable as a load-bearing component, and twists the optical cable, electrical cable, shielding film, etc. in the core of the cable. One end of the optical cable and electrical cable is connected to the electronic circuit and network circuit of the mother ship's electronic pod, and the other end is connected to the mother ship's network server. In order to maintain a better communication effect, the acoustic transceiver terminal of the mother ship's electronic pod has a tracking function, which always points to the signal relay station of the escort submersible. When sending information to a manned submersible in deep water, the information transmitted to the mother ship's electronic pod through an optical cable or an electric cable is converted into an acoustic signal by an acoustic transducer, and the acoustic transmitter is connected to the acoustic signal transceiver terminal to send the information to the signal relay station of the escorting submersible; when a manned submersible in deep water uploads information to the mother ship's network server, the acoustic transceiver terminal of the mother ship's electronic pod receives the acoustic signal transmitted through the signal relay station of the escorting submersible, and is connected to the acoustic receiver of the mother ship's electronic pod to receive the information, and is converted into an electrical signal by the acoustic transducer of the mother ship's electronic pod, and uploaded to the mother ship's network server through an optical cable or an electric cable.

[0058] like Figure 1 , Figure 2 , Figure 4 As shown, the signal relay station of the escort submersible includes two groups of signal transmission channels composed of acoustic receivers, acoustic amplifiers, and acoustic transmitters, and two acoustic transceiver terminals. In order to maintain a good communication effect, the two acoustic transceiver terminals have a tracking function: one acoustic transceiver terminal always points to the mother ship electronic pod deployed by the mother ship, and the other acoustic transceiver terminal always points to the manned submersible in deep diving. When sending information to a manned submersible in deep water, the acoustic signal transceiver terminal on the escort submersible pointing to the mother ship's electronic pod receives the acoustic signal transmitted from the mother ship's electronic pod and connects to the acoustic receiver (1) of the escort submersible signal relay station. The acoustic signal amplifier of the escort submersible signal relay station amplifies the acoustic signal and then connects to the acoustic signal transceiver terminal pointing to the manned submersible through the acoustic transmitter (1) of the escort submersible signal relay station to send the information to the manned submersible in deep water. When the manned submersible in deep water uploads information to the mother ship's network server, the acoustic signal transceiver terminal pointing to the manned submersible receives the acoustic signal transmitted from the manned submersible and connects to the acoustic receiver (2) of the escort submersible signal relay station. The acoustic signal amplifier of the escort submersible signal relay station amplifies the acoustic signal and then connects to the acoustic signal transceiver terminal pointing to the mother ship's electronic pod through the acoustic transmitter (2) of the escort submersible signal relay station to send the information to the mother ship's electronic pod.

[0059] like Figure 1 , Figure 2 , Figure 5As shown, the manned submersible acoustic wave transceiver includes an acoustic wave transmitter, an acoustic wave receiver, an acoustic wave transducer, and an acoustic wave transceiver terminal pointing to the escort submersible signal relay station. In order to maintain a good communication effect, the acoustic wave transceiver terminal of the manned submersible has a tracking function and always points to the escort submersible. When the manned submersible in deep diving downloads information, the acoustic wave transceiver terminal pointing to the escort submersible signal relay station receives the acoustic wave signal transmitted from the escort submersible signal relay station and connects to the acoustic wave receiver. The acoustic wave transducer of the manned submersible acoustic wave transceiver converts the acoustic wave signal into an electrical signal, and transmits the information to the manned submersible computer via the network switch of the manned submersible short-range communication network; when the manned submersible in deep diving uploads information, the manned submersible computer sends the information to the manned submersible acoustic wave transceiver via the network switch, and the acoustic wave transducer converts the electrical signal into an acoustic wave signal. The acoustic wave transmitter connects to the signal transceiver terminal pointing to the escort submersible and sends the information to the escort submersible signal relay station.

[0060] like Figure 2 As shown, the manned submersible working condition detection unit is for the configuration of the component systems of the manned submersible during underwater operations. This embodiment only sets the basic configuration, and the actual situation is much more complicated than this implementation. It includes an in-cabin working condition detection unit, an out-cabin working condition detection unit and a standby working condition detection unit. Among them, the in-cabin working condition detection unit and the out-cabin working condition detection unit are two basic working condition detection units, and do not include specific instruments / equipment configured to perform diving missions. The working condition detection of instruments, equipment, energy reserves, life support, crew health status, etc. in the manned cabin of the manned submersible is merged into the in-cabin working condition detection unit in this embodiment; the working condition detection of the working status of the power unit, navigation attitude control device, optical instruments and equipment carried, electronic and mechanical devices, working tools and communication positioning equipment outside the manned cabin of the manned submersible is merged into the out-cabin working condition detection unit. With the development trend of manned submersibles performing deep-sea diving missions on a regular basis and the diversity of deep-sea diving missions, in actual application, a backup operating condition detection unit can be added on the basis of the examples of the present invention to improve the flexibility of the functional configuration of the manned submersible.

[0061] like Figure 2 As shown in the figure, the working condition detection unit of the manned submersible includes working condition detection module, sensor, actuator, monitoring equipment, and unit network connection interface. The capacity of each interface adopts redundant design, and reserved channels are expanded for the detection and monitoring objects. The working condition detection module adopts universal, serialized, and combined design, and is made into universal parts or standard parts, which provides convenience for optional configuration when the manned submersible performs different types and different natures of tasks, and can also reduce the workload of maintenance. The working condition detection module is classified and designed to detect observation data, communication data, and detection data, etc.

[0062] like Figure 2As shown in the figure, the computer of the manned submersible is an industrial control computer. The control panel and operating handle of the manned submersible are directly connected to the computer of the manned submersible as external devices of the computer of the manned submersible. It is interconnected and interoperable with the working condition detection unit of the manned submersible through a network switch to maintain real-time two-way communication, forming a short-range communication network of the manned submersible. It is interconnected and interoperable with the mother ship network server through an underwater data communication link to access the manned submersible remote communication network. The manned submersible computer is equipped with a multi-function display terminal, which uses split-screen / single-screen / picture-in-picture display and other methods to display the working condition information of the manned submersible and its instruments and equipment, etc., and supports multi-task operation.

[0063] The manned submersible computer is an intelligent unit of the manned submersible short-range communication network. Its main functions include recording the working condition information of the manned submersible, controlling the component systems of the manned submersible and automatically detecting the working condition information of the manned submersible, automatically processing information and generating charts and reports, keeping in touch with the mother ship network server throughout the process and uploading the working condition data of the manned submersible. The working condition information of the manned submersible is recorded according to the voyage of the deep diving mission, and the working condition data is obtained and recorded by scanning each working condition detection unit in sequence. Since the manned submersible completes a cycle of scanning in a very short time, the working condition information obtained is the real-time status of the manned submersible; the manned submersible computer compares the received information with the set requirements, analyzes it through calculation, historical data retrieval, comparison, etc., and analyzes and processes the information by making charts. After obtaining the processing results, together with the original data, it is encrypted and compressed into a data packet and uploaded to the mother ship network server for backup.

[0064] like Figure 2 As shown in the figure, the mother ship network server is the intelligent unit for the entire manned submersible underwater operation. Its function is to back up the working condition information of the manned submersible in the deep diving mission, and to control the whole area and record the information transmitted during the underwater operation of the manned submersible. The mother ship network server backs up and records information according to the work log of the manned submersible, and automatically generates periodic reports in the form of graphs and tables. The display screen in the command cabin of the mother ship is connected to the display screen of the mother ship, and the working condition information of each component system during the underwater operation of the manned submersible is displayed in a split screen / single screen / picture-in-picture display mode, and supports multi-task operation.

[0065] like Figure 2 As shown, the full-area communication network for manned submersible underwater operations adopts real-name management, and grants different levels of information access permissions to manned submersible crew members, commanders, operation and maintenance support personnel, technical experts from the shore-based command center, visitors, etc.

[0066] like Figure 2As shown in the figure, when the global communication network for underwater operations of manned submersibles responds to abnormal warnings, the computer of the manned submersibles will first issue an early warning when it detects an abnormality in a certain working condition detection unit. The working condition information and analysis results are uploaded to the mother ship network server. The mother ship network server immediately responds to the early warning, starts the abnormal phenomenon processing event program, and summons professional technicians on the manned submersible remote communication network to pay attention to the abnormal situation according to the location of the abnormality, and provide professional and scientific decisions. While responding to the early warning, the mother ship network server records all information transmitted on the global communication network for underwater operations of manned submersibles.

[0067] The global communication network for underwater operations of manned submersibles summarizes data according to the stage of the mission performed. Records of abnormal situations should include the location and time of the abnormality, the disposal methods of professional technicians, etc., which serve as archival data for the entire life cycle of the manned submersible.

[0068] In this implementation, the working condition information of each component system of multiple manned submersibles in the global communication network for underwater operations of manned submersibles fully utilizes the high-speed operation characteristics of computers, and the acquisition, processing, and distribution of the working conditions of manned submersibles are automatically completed within milliseconds, avoiding manual transcription and transmission of information, and eliminating the phenomenon of miscopying and mistransmission of information. It has innovated the working methods of personnel in various positions, focused on the work priorities of professional and technical personnel, and is conducive to strengthening the team of operation and maintenance personnel, and stimulated the spirit of teamwork.

[0069] The above description is an explanation of the present invention, not a limitation of the present invention. The scope of the present invention is defined in the claims. Any form of modification may be made within the scope of protection of the present invention.
