Description

Technical Field

[0001] The utility model relates to the technical field of ocean engineering, and particularly relates to a monitoring data acquisition device for an underwater data cabin. Background Art

[0002] An underwater data cabin is a unit of a subsea data center, which includes power supply equipment, data center IT (Information Technology) equipment, and monitoring equipment. During the use of the underwater data cabin, it is necessary to collect the in-cabin monitoring data and troubleshoot possible in-cabin faults to ensure the safety of the underwater data cabin.

[0003] Currently, generally, the in-cabin monitoring data of the underwater data cabin is obtained and troubleshot by connecting to the formal power supply and network before launching. Or, if the underwater data cabin has been launched, it is necessary to salvage the underwater data cabin ashore, open the data cabin and enter the interior to obtain the in-cabin monitoring data for troubleshooting.

[0004] The problems with the above solutions are that if the power supply and network are not ready before launching, the in-cabin monitoring data cannot be obtained, or if the in-cabin monitoring data is obtained by salvaging the underwater data cabin ashore after launching, it will lead to low data acquisition efficiency and low fault troubleshooting efficiency, thus affecting the safety of the underwater data cabin. Summary of the Utility Model

[0005] Therefore, the technical problem to be solved by the utility model is to overcome the problems of low in-cabin monitoring data acquisition efficiency and low fault troubleshooting efficiency in the prior art, which in turn affect the safety of the underwater data cabin, and thus provide a monitoring data acquisition device for an underwater data cabin.

[0006] The utility model provides a monitoring data acquisition device for an underwater data cabin. The underwater data cabin includes a monitoring system for collecting the in-cabin monitoring data of the underwater data cabin. The device includes a watertight socket, a watertight connector, a first cable, a second cable, and a mobile monitoring terminal.

[0007] The watertight socket is arranged on the outer surface of the underwater data cabin, and the watertight socket and the monitoring system are connected by a first cable.

[0008] The watertight connector is inserted into the watertight socket, obtains the in-cabin monitoring data of the underwater data cabin collected by the monitoring system through the watertight socket and the first cable, and transmits it to the mobile monitoring terminal through the second cable.

[0009] After the watertight connector is inserted into the watertight socket, the present utility model obtains the in-cabin monitoring data of the underwater data cabin collected by the monitoring system through the first cable and transmits it to the mobile monitoring terminal through the second cable. Whether the underwater data cabin is launched or not, the in-cabin monitoring data can be directly obtained, realizing remote real-time monitoring of the underwater data cabin, avoiding the situation in the related art of salvaging the underwater data cabin ashore to obtain data for troubleshooting or waiting to access power and network to obtain data for troubleshooting, improving the efficiency of data acquisition, and thus improving the troubleshooting efficiency and ensuring the safety of the underwater data cabin.

[0010] In an optional implementation manner, the second cable includes a power line and a network line. The watertight connector is connected to a movable external test power supply and a mobile monitoring terminal through the second cable. The power line is used to transmit the power provided by the external test power supply, and the network line is used to transmit the network signal provided by the mobile monitoring terminal.

[0011] By adopting a movable external test power supply and a mobile monitoring terminal, the present utility model allows the acquisition of in-cabin monitoring data at different locations without the support of fixed infrastructure, enhancing the flexibility and portability of on-site operations. Moreover, the second cable connects the external test power supply and the mobile monitoring terminal, enabling the acquisition of external power and external network to support the acquisition of in-cabin monitoring data.

[0012] In an optional implementation manner, the watertight socket includes a power line interface and a network line interface. The power line interface transmits the power input by the watertight connector to the monitoring system through the first cable, and the network line interface transmits the network signal input by the watertight connector to the monitoring system through the first cable.

[0013] The present utility model processes power supply and network signals through independent interfaces, effectively avoiding mutual interference between signals, ensuring the stability of power and network signal transmission, and being able to provide external power and external network for the monitoring system of the underwater data cabin, guaranteeing the smooth acquisition of in-cabin monitoring data.

[0014] In an optional implementation manner, the device further includes a power supply module for powering the monitoring system;

[0015] The power supply module includes a UPS power supply and an external test power supply, and the UPS power supply and the external test power supply are interlocked with each other.

[0016] The present utility model powers the monitoring system through the UPS power supply and the external test power supply, avoiding the situation of being unable to supply power in case of a single power supply failure, which may lead to the inability to obtain in-cabin monitoring data, improving the stability of data acquisition. Moreover, the UPS power supply and the external test power supply are interlocked with each other, further improving the stability of data acquisition.

[0017] In an alternative embodiment, the monitoring system includes a test switch, a video monitoring switch, and an environmental monitoring switch. The test switch includes a first network interface, a second network interface, and a third network interface. The test switch is connected to a first cable through the first network interface;

[0019] In the present utility model, when there is power supply, the test switch is respectively connected to the video monitoring switch and the environmental monitoring switch through network interfaces, and the corresponding networks of the two switches are connected, so that it is not necessary to separately obtain the monitoring data of the two networks, improving the convenience and efficiency of data acquisition.

[0020] In an alternative embodiment, the mobile monitoring terminal is further configured to log in to the video monitoring network and the environmental monitoring network, and obtain the video monitoring data collected by the video monitoring switch and the environmental monitoring data collected by the environmental monitoring switch.

[0021] In the present utility model, the mobile monitoring terminal directly logs in to the video monitoring network and the environmental exchange network to obtain the in-cabin monitoring data, realizing remote monitoring of the underwater data cabin.

[0022] In an alternative embodiment, when the UPS power supply is powered on, the UPS power supply is used to supply power to the devices in the monitoring system except the test switch, and an external test power supply is used to supply power to the test switch.

[0023] In the present utility model, by using an external test power supply to supply power only to the test switch, the acquisition of in-cabin monitoring data is not affected whether the UPS power supply is powered or not.

[0024] In an alternative embodiment, when the UPS power supply is out of power, the external test power supply is used to supply power to the monitoring system.

[0025] In the present utility model, when the UPS power supply is out of power, an external test power supply is used to supply power to the entire monitoring system, avoiding the normal operation of the monitoring system being affected due to lack of power supply, and ensuring the normal operation of the underwater data cabin.

[0035] The following will clearly and completely describe the technical solutions of the present utility model with reference to the drawings. Obviously, the described embodiments are some, but not all, of the embodiments of the present utility model. All other embodiments obtained by those of ordinary skill in the art without creative efforts based on the embodiments of the present utility model belong to the protection scope of the present utility model.

[0036] In the description of the present utility model, it should be noted that the terms "first", "second", and "third" are only used for descriptive purposes and cannot be construed as indicating or implying relative importance.

[0037] Underwater data cabins are commonly used in fields such as marine scientific research, environmental monitoring, hydrological measurement, and IT computing power. They are an important part of the subsea data center. Collecting the in-cabin monitoring data of the underwater data cabin to detect possible in-cabin fault problems can ensure the safety of the underwater data cabin and thus guarantee the collection of underwater data by the underwater data cabin. In related technologies, the in-cabin monitoring data of the underwater data cabin is mainly obtained by connecting to the formal power supply and network before launching for troubleshooting. Or, after launching, the underwater data cabin is salvaged ashore, the data cabin is opened to enter the interior to obtain the in-cabin monitoring data for troubleshooting, which has problems of low data acquisition efficiency and low fault troubleshooting efficiency.

[0038] An embodiment of the present invention provides a monitoring data acquisition device for an underwater data cabin, as Figure 1 shown. The underwater data cabin 1 includes a monitoring system 2, and the monitoring system 2 is used to collect the in-cabin monitoring data of the underwater data cabin 1. The device includes a watertight socket 3, a watertight connector 4, a first cable 5, a second cable 6, and a mobile monitoring terminal 7;

[0039] The watertight socket 3 is arranged on the outer surface of the underwater data cabin 1, and the watertight socket 3 and the monitoring system 2 are connected by the first cable 5;

[0040] The watertight connector 4 is inserted into the watertight socket 3, obtains the in-cabin monitoring data of the underwater data cabin 1 collected by the monitoring system 2 through the watertight socket 3 and the first cable 5, and transmits it to the mobile monitoring terminal 7 through the second cable 6.

[0041] Specifically, when the underwater data cabin 1 has not been launched yet, the watertight connector 4 can be directly inserted into the watertight socket 3. After obtaining the in-cabin monitoring data, it is transmitted to the mobile monitoring terminal 7 through the second cable 6. Since the mobile monitoring terminal 7 can be moved, the distance between the mobile monitoring terminal 7 and the watertight connector 4 can be adjusted by moving the mobile monitoring terminal 7 to meet the requirements of stable data transmission, without setting the length of the second cable 6. When the underwater data cabin 1 has been launched, it is necessary for a person to dive underwater to insert the watertight connector 4 into the watertight socket 3. And the mobile monitoring terminal 7 is generally arranged on the operation and maintenance ship on the water surface. Therefore, it is necessary to ensure that the length of the second cable 6 meets the distance between the mobile monitoring terminal 7 and the underwater data cabin 1 to ensure stable transmission of the in-cabin monitoring data. Among them, the watertight socket 3 is a wet-pluggable socket, ensuring that when the underwater data cabin 1 is working underwater, water and other pollutants will not enter the interior of the socket, so as to realize reliable transmission of signals and electricity in the underwater environment. The watertight connector 4 also has the wet-pluggable function to ensure reliable data transmission by inserting into the watertight socket 3 underwater. The first cable 5 and the second cable 6 are waterproof cables to ensure reliable data transmission underwater. The mobile monitoring terminal 7 can be a computer, a mobile phone, etc. This is only an example and not limited thereto.

[0042] In one embodiment, as Figure 1 shown, the second cable 6 includes a power line and a network line. The watertight connector 4 is connected to the movable external test power supply 8 and the mobile monitoring terminal 7 through the second cable 6. The power line is used to transmit the power provided by the external test power supply 8, and the network line is used to transmit the network signal provided by the mobile monitoring terminal 7.

[0043] Specifically, the second cable 6 is used to provide an external power supply and an external network for the underwater data cabin 1, that is, the power provided by the external test power supply 8 and the network signal provided by the mobile monitoring terminal 7. The positions of the external test power supply 8 and the mobile monitoring terminal 7 are close to reduce the length of the second cable 6, thereby saving costs. Among them, the external test power supply 8 is 220V alternating current. Optionally, the position of the mobile monitoring terminal 7, the position of the external test power supply 8, the voltage, etc. can be adjusted according to actual needs, which is not limited thereto.

[0044] In one embodiment, the watertight socket 3 includes a power line interface and a network line interface. The power line interface transmits the power input by the watertight connector 4 to the monitoring system 2 through the first cable 5, and the network line interface transmits the network signal input by the watertight connector 4 to the monitoring system 2 through the first cable 5.

[0045] Specifically, the watertight socket 3 is provided with a 6-core interface, of which 2 cores are power line interfaces and 4 cores are 10M network line interfaces, which not only meet the transmission requirements of power and network signals, but also reduce the pin requirements. The watertight socket 3 and the watertight connector 4 realize the transmission of power and network signals between the first cable 5 and the second cable 6, so as to realize power supply and network supply for the monitoring system 2 in the underwater data cabin 1.

[0046] In one embodiment, the device further includes a power supply module 9 for supplying power to the monitoring system 2; the power supply module 9 includes a UPS power supply 10 and an external test power supply 8, and the UPS power supply 10 and the external test power supply 8 are interlocked with each other.

[0047] Specifically, the UPS power supply 10 (Uninterruptible Power Supply), that is, an uninterruptible power supply system. In the present invention, the UPS power supply 10 has no external power supply and uses an internal battery to supply 220V alternating current to the underwater data cabin 1, so as to provide a continuous and stable power supply for the underwater data cabin 1 and ensure the uninterrupted operation of the underwater data cabin 1. The external test power supply 8 in the power supply module 9 is the external test power supply 8 connected to the watertight connector 4 through the power line interface, and is obtained by connecting to the watertight connector 4 through the second cable 6 and transmitting the power after inserting into the watertight socket 3 and then transmitting the power through the first cable 5. The UPS power supply 10 and the external test power supply 8 are interlocked with each other, that is, when both power supplies are powered on, only one power supply supplies power to the monitoring system 2, and the other power supply is cut off by the internal control power supply.

[0048] In one embodiment, the monitoring system 2 includes a test switch 21, a video monitoring switch 22, and an environmental monitoring switch 23. The test switch 21 includes a first network interface, a second network interface, and a third network interface. The test switch 21 is connected to the first cable 5 through the first network interface. When there is power supply from the power supply module 9, the test switch 21 is used to access the video monitoring switch 22 through the second network interface and access the environmental monitoring switch 23 through the third network interface, so as to connect the video monitoring network of the video monitoring switch 22 and the environmental monitoring network of the environmental monitoring switch 23.

[0049] Specifically, Figure 2 is a schematic diagram of the monitoring system provided by the embodiment of the present invention. As Figure 2 shown, Lan1 represents the first network interface, Lan2 represents the second network interface, and Lan3 represents the third network interface. All three interfaces are RJ45 interfaces, set to a 10M network. Network communication can be achieved by using a 4-core network cable for connection. The test switch 21 is connected to the network cable in the first cable 5 through Lan1, connected to the video monitoring switch 22 through Lan2, and connected to the environmental monitoring switch 23 through Lan3. The video monitoring switch 22 is connected to the camera, providing power and network for the camera. The camera collects in-cabin video data and transmits it to the video monitoring network of the video monitoring switch 22. The environmental monitoring switch 23 is connected to multiple sensors, providing power and network for the multiple sensors. The multiple sensors collect data such as air pressure, temperature, humidity, water ingress situation, refrigerant temperature, and condensation pressure in the cabin and transmit it to the environmental monitoring network of the environmental monitoring switch 23. When there is power supply from the power supply module 9, that is, when any one of the UPS power supply 10 and the external test power supply 8 supplies power to the monitoring system 2, the test switch 21, the video monitoring switch 22, and the environmental monitoring switch 23 can be normally powered on and work. The test switch 21 is connected to the video monitoring switch 22 and the environmental monitoring switch 23 through the second network interface and the third network interface respectively, and can connect the completely isolated video monitoring network and environmental monitoring network, so that the information of the two networks can be directly obtained without obtaining them separately, thereby improving the efficiency of data acquisition. When the power supply module 9 no longer supplies power to the test switch 21, the test switch 21 restores the isolation state of the two networks.

[0050] In one embodiment, the mobile monitoring terminal 7 is further used to log in to the video monitoring network and the environmental monitoring network to obtain the video monitoring data collected by the video monitoring switch 22 and the environmental monitoring data collected by the environmental monitoring switch 23.

[0051] Specifically, since the mobile monitoring terminal 7 provides a network for the monitoring system 2, that is, a network link is established between the mobile monitoring terminal 7 and the test switch 21 in the monitoring system 2, and the test switch 21 is also connected to the video monitoring switch 22 and the environmental monitoring switch 23 and the networks corresponding to the two switches are connected, the mobile monitoring terminal 7 can directly log in to the video monitoring network and the environmental monitoring network to obtain data, and obtain video monitoring data and environmental monitoring data. Among them, the video monitoring data can be the monitoring video in the cabin, and the environmental monitoring data can be data such as the air pressure, temperature, humidity, water ingress situation, refrigerant temperature, and condensation pressure in the cabin. By obtaining the environmental monitoring data, it is possible to check for faults such as leakage, water ingress, and refrigerant leakage in the underwater data cabin 1, and by obtaining the video monitoring data, it is possible to check for faults such as physical damage to the equipment in the cabin, so as to ensure the safety of the underwater data cabin 1.

[0052] In one embodiment, as Figure 2 shown, when the UPS power supply 10 is powered on, the UPS power supply 10 is used to supply power to the devices in the monitoring system 2 except for the test switch 21, and the external test power supply 8 is used to supply power to the test switch 21.

[0053] Specifically, referring to Figure 2 shown, L (Live Wire) represents the live wire, and N (Neutral Wire) represents the neutral wire. K1 is the control relay of the external test power supply 8, and K2 is the control relay of the UPS power supply 10. The two control relays each have multiple contacts in Figure 2 . After the control relay K2① of the UPS power supply 10 is closed, the main contact (i.e., normally open contact) ② of K2 is closed to supply power to the monitoring system 2. At the same time, the auxiliary contact (i.e., normally closed contact) ③ of K2 is opened to cut off the power supply circuit of the control relay K1④ of the external test power supply 8, and the main contact (i.e., normally open contact) ④ of K1 will not be closed, ensuring that even if there is an external test power supply 8, the monitoring system 2 is still powered by the UPS power supply 10. The test switch 21 only serves to obtain the monitoring data in the cabin and does not participate in other operations of the underwater data cabin 1. The UPS power supply 10 is the main power supply of the underwater data cabin 1. Therefore, the test switch 21 only needs to be powered by the external test power supply 8, so that when the external test power supply 8 shuts off the power supply, the monitoring system 2 will not be short-term power supply interrupted due to power switching, and regardless of whether the UPS power supply 10 supplies power or not, it does not affect the process of obtaining the monitoring data in the cabin.

[0054] In one embodiment, as Figure 2 shown, when the UPS power supply 10 is out of power, the external test power supply 8 is used to supply power to the monitoring system 2.

[0055] Specifically, referring to Figure 2As shown, when the UPS power supply 10 runs out of power, the control relay K2 loses power, the main contact ② of K2 disconnects, and the power supply circuit from the UPS power supply 10 to the monitoring system 2 is cut off. At the same time, the auxiliary contact ③ of K2 closes, the control relay K1① of the external test power supply 8 gets powered on and operates to pull in, and the main contact K④ pulls in and closes to supply power to the monitoring system 2. Moreover, the main contact ② of the control relay K2 of the UPS power supply 10 is in the open state, and the external test power supply 8 and the UPS power supply 10 are completely isolated, ensuring that the two AC power supplies will not be connected in parallel and short-circuited.

[0056] In one embodiment, as shown in Figure 2 shown Figure 2 the power supply switching circuit of the test switch 21 shown in is designed with electrical isolation from the UPS power supply 10 and the external test power supply 8. When the external test power supply 8 is not powered, the interfaces of the power line and the network line of the first cable 5 connected to the monitoring system 2 are isolated. Even if the watertight socket 3 leaks and fails, it will not affect the normal operation of the monitoring system 2.

[0057] In one embodiment, the watertight socket 3 further includes a watertight plug and a watertight protective cover.

[0058] Specifically, the watertight plug is usually installed in the unused jacks of the watertight socket 3 to ensure the watertightness of the whole system. And even if the watertight performance fails and water enters, it can ensure that the power line interface and the network line interface are completely in a non-powered isolated state, and there will be no leakage corrosion and then water leakage endangering the underwater data cabin 1. The design of the watertight plug will ensure a perfect match with the socket jacks, for example, tightly combined through threads, buckles or other fixing methods. The watertight protective cover covers the entire watertight socket 3. The watertight protective cover needs to be opened before the watertight connector 4 is inserted into the watertight socket 3. The watertight protective cover provides a more comprehensive function of waterproof, dustproof and mechanical protection.

[0059] In one embodiment, as shown in Figure 1 shown, the first cable 5 and the second cable 6 are bundled cables containing power lines and network lines.

[0060] Specifically, since the second cable 6 connects the mobile monitoring terminal 7 and the external test power supply 8 to provide external network and external power for the underwater data cabin 1, the second cable 6 needs to contain both power lines and network lines at the same time. The second cable 6 transmits power and network signals to the first cable 5 through the watertight connector 4 and the watertight socket 3. Therefore, the first cable 5 also needs to contain both power lines and network lines at the same time. The first cable 5 and the second cable 6 adopt bundled cables, integrating the network lines and the power lines in one cable, improving the anti-interference ability and ensuring the network quality during the process of obtaining the in-cabin monitoring data.

[0061] After the water-tight connector of the present utility model is inserted into the water-tight socket, the in-cabin monitoring data of the underwater data cabin collected by the monitoring system is obtained through the first cable and transmitted to the mobile monitoring terminal through the second cable. Whether the underwater data cabin is launched or not, the in-cabin monitoring data can be directly obtained, realizing remote real-time monitoring of the underwater data cabin, avoiding the need to salvage the underwater data cabin ashore to obtain data for troubleshooting in the related art or waiting to access power and network to obtain data for troubleshooting, improving the efficiency of data acquisition, and thus improving the troubleshooting efficiency and ensuring the safety of the underwater data cabin.

[0062] Obviously, the above embodiments are merely examples given for clear illustration and not limitations on the implementation manners. For those of ordinary skill in the art, other different forms of changes or variations can be made based on the above description. It is not necessary and impossible to list all the implementation manners here. And the obvious changes or variations derived therefrom are still within the protection scope of the present utility model.
