Description

Technical Field

[0001] This application relates to the field of electrical equipment, and more specifically, to a cable heating monitoring system and a cable heating monitoring method. Background Technology

[0002] Ship fires, due to their unique environment (limited space, concentrated combustibles, and location at sea) and inherent characteristics (difficult evacuation, deadly smoke, and limited rescue), are extremely prone to getting out of control once they occur, causing catastrophic consequences far exceeding those of land fires.

[0003] Current ship fire monitoring solutions can only issue alarms after a fire has occurred. However, ship fires spread rapidly and are difficult to escape and rescue.

[0017] According to one aspect of the embodiments of this application, a computer-readable medium is provided having a computer program stored thereon, which, when executed by a processor, implements the method described in the above embodiments.

[0019] In some embodiments of this application, a cable heating monitoring system is provided, comprising multiple temperature detection probes, a main control box communicating with each temperature detection probe, and a power distribution system communicating with the main control box.

[0028] In this application embodiment, the terms "module" or "unit" refer to a computer program or part of a computer program that has a predetermined function and works with other related parts to achieve a predetermined goal, and can be implemented wholly or partially using software, hardware (such as processing circuitry or memory), or a combination thereof.

That is, these functional entities can be implemented in software, in one or more hardware modules or integrated circuits, or in different network and / or processor devices and / or microcontroller devices.

[0030] The flowcharts shown in the accompanying drawings are merely illustrative and do not necessarily include all content and operations / steps, nor do they necessarily have to be performed in the described order. For example, some operations / steps can be broken down, while others can be combined or partially combined; therefore, the actual execution order may change depending on the specific circumstances.

[0031] Ship cables can age due to high temperatures and be corroded by salt, leading to a decline in cable performance, which may cause overheating and fire.

[0032] Given that fires caused by cable overheating during ship navigation can pose a significant danger to the vessel, it is necessary to monitor cable overheating to prevent such incidents from occurring in the first place.

[0033] According to one aspect of this application, a cable heating monitoring system is first provided. The cable heating monitoring system provided by this application can be used in any location requiring monitoring of cable heating, such as ships. It can be applied to cargo ships, passenger ships, and other types of vessels. The cable heating monitoring system provided by this application can be installed on ships.

[0034] On ships, cables can be used to power various electrical equipment such as water pumps, refrigerated containers, power plants, substations, and motors.

[0035] The cable heating monitoring system includes multiple temperature detection probes, which are deployed at the junctions of different cables.

[0036] A cable junction is an area in which multiple cables intersect, merge, or are laid in parallel in physical space.

[0037] Temperature detection probes can be installed at some or all of the cable junctions on the ship. Each temperature detection probe can be used to detect the temperature at the cable junction where it is installed.

[0038] Several temperature detection probes can be installed at each cable junction, and these probes are used to detect the temperature at the same cable junction.

[0039] Because cable heating has a wide heating range, installing temperature detection probes at cable junctions can ensure comprehensive monitoring of cable heating and reduce the number of probes required, thus saving costs.

[0040] The temperature detection probe can be a resistance temperature sensor probe based on a resistance temperature detector (RTD). The RTD can be a PT100, a temperature sensor based on platinum (Pt) material whose resistance is linearly related to temperature. Using an RTD-based temperature sensor probe to monitor cable heating is cost-effective, economical, and practical. The temperature detection probe can also have wireless transmission capabilities, allowing it to transmit the detected temperature information wirelessly. Wireless transmission offers better adaptability, is not limited by geographical environment, and is suitable for information transmission in complex environments such as ships, reducing space occupation and cabling costs. The wireless transmission function of the temperature detection probe can be achieved via Bluetooth or WiFi.

[0041] Of course, a distributed fiber optic temperature sensing system (DTS) or a thermal imager can be used to replace the temperature detection probe for temperature detection. Alternatively, the temperature detection probe can be combined with a distributed fiber optic temperature sensing system or a thermal imager for temperature detection.

[0042] The cable heating monitoring system also includes a main control box, which is connected to each temperature detection probe. The main control box stores the first correspondence between the identification information of the temperature detection probe and the cable intersection location, the second correspondence between the cable intersection location and the cable information, and the third correspondence between the cable information and the equipment information.

[0043] A cable junction can correspond to the identification information of one or more temperature detection probes; a cable junction can correspond to one or more cable information; a cable information can correspond to one or more device information.

[0044] Specifically, the first correspondence can be manually configured to the main control box, while the second and third correspondences can be automatically read by the main control box.

[0045] Figure 1 This is an application flowchart of a cable heating monitoring system according to an embodiment of this application. Please refer to [link / reference]. Figure 1 As shown, cable junction points need to be manually selected, and PT1000 probes need to be placed at the selected junction points. The cable junction points can be some or all of the cable junction points on the ship selected according to the cable register. The cable register records all the cable junction points on the ship and the correspondence between these cable junction points and cable information. After the PT1000 probes are placed, a corresponding address code can be set for the cable junction point as the cable junction location, and the first correspondence between the identification information of the temperature detection probe (PT1000 probe) and the cable junction location (the location of the cable junction point) is configured in the main control box of the cable heating monitoring system.

[0046] Please continue reading Figure 1 It can also generate cable registers that include all cable nodes (cable junctions) on the ship. For example, cable registers can be obtained by analyzing the ship's electrical design drawings.

[0047] Then, the cable registers can be grouped according to the cable junction points (i.e., the locations of temperature detection probes) involved in the first correspondence. Based on the correspondence between the cable junction points and cable information involved in each group and the address codes corresponding to the cable junction points, a second correspondence between the cable junction locations and cable information can be established to facilitate querying.

[0048] In this way, the main control box can obtain and store the first and second correspondences.

[0049] Similarly, the main control box can also obtain and store the third correspondence between cable information and equipment information from the ship's electrical design drawings or design documents.

[0050] A wireless network can also be deployed on the ship, enabling the main control box to communicate wirelessly with the temperature probes. Wireless network equipment (such as routers) can be deployed in densely populated areas of the probes, for example, at the geometric center of all temperature probes, to ensure a stable signal connection between the probes and the wireless network equipment. The temperature probes can then transmit temperature information in real time via the wireless network.

[0051] The main control box is used to receive temperature information reported by each temperature detection probe, and when it is determined that there is an anomaly in the temperature information reported by the target temperature detection probe based on the temperature information reported by each temperature detection probe, it determines the equipment information of the power equipment associated with the cable detected by the target temperature detection probe according to the first correspondence, the second correspondence, and the third correspondence.

[0052] The messages reported by each temperature detection probe can include temperature information and the identification information of the temperature detection probe. The main control box can first query the first correspondence based on the identification information of the temperature detection probe with abnormal temperature information to obtain the cable junction location; then, it can query the second correspondence between the cable junction location and the cable information to obtain the corresponding cable information; finally, it can obtain the corresponding equipment information based on the third correspondence between the cable information and the equipment information.

[0053] A corresponding temperature threshold can be set for each probe. The temperature thresholds for different probes can be the same or different. When the temperature information reported by the target temperature detection probe reaches the temperature threshold corresponding to that probe, it can be determined that the temperature information reported by the target temperature detection probe is abnormal.

[0054] To prevent abnormal temperature information detection due to temperature probe malfunction, as mentioned above, multiple temperature probes can be deployed at each cable junction. Therefore, when it is determined that the temperature information reported by the target temperature probe is abnormal based on the temperature information reported by each temperature probe, it can be determined whether the difference between the temperature information reported by other target temperature probes deployed at the same cable junction as the target temperature probe and the temperature information reported by the target temperature probe is less than a predetermined temperature difference threshold. If so, the equipment information of the power equipment associated with the cable detected by the target temperature probe can be determined according to the first correspondence, the second correspondence, and the third correspondence.

[0055] The advantage of doing this is that the temperature information reported by the target temperature detection probe can be verified by other temperature detection probes, ensuring the accuracy of the monitored temperature information.

[0056] The cable heating monitoring system may also include a power distribution system, which is connected to the main control box. The power distribution system is used to control the power supply to various electrical devices. The main control box can also send the device information of the electrical equipment associated with the cable detected by the target temperature detection probe to the power distribution system. The power distribution system is also used to obtain the device information of the electrical equipment associated with the cable detected by the target temperature detection probe from the main control box, perform current verification on the corresponding electrical equipment based on the device information, and perform a disconnection operation on the electrical equipment whose current verification result shows abnormal current fluctuation.

[0057] The power distribution system has the ability to disconnect and activate equipment.

[0058] Considering that cable heating is mostly caused by power cables of high-power equipment, the power distribution system can sort the information of each equipment and the corresponding power equipment in descending order of power to ensure that the power equipment most likely to cause cable heating is checked first, which improves the efficiency of identifying power equipment with abnormal current fluctuations to a certain extent.

[0059] The power distribution system can be further used to: determine the equipment type of power equipment whose current verification result is abnormal; if the equipment type is the target equipment type, then activate the backup equipment corresponding to the power equipment whose current verification result is abnormal, and perform a disconnection operation on the power equipment whose current verification result is abnormal.

[0060] If the equipment type of the power equipment with abnormal current fluctuations as determined by the current verification result is not the target equipment type, then the power equipment with abnormal current fluctuations as determined by the current verification result can be directly disconnected.

[0061] Equipment types can be categorized into critical equipment and non-critical equipment, with the target equipment type being critical equipment. Critical equipment generally has corresponding backup equipment. In this embodiment, by first activating the corresponding backup equipment for the power equipment experiencing abnormal current fluctuations, and then disconnecting the power equipment experiencing abnormal current fluctuations, it can be ensured that disconnecting the power equipment experiencing abnormal current fluctuations will not affect the safe navigation of the ship.

[0062] Important equipment could be servo motors, propulsion system oil pumps, etc.; non-critical equipment could be electric stoves, fans, air conditioners, induction cookers, lights, refrigerators, etc.

[0063] In one embodiment of this application, the power distribution system can be further configured to: determine whether a power device with an abnormal current fluctuation as the current verification result is a device that can be disconnected; if a power device with an abnormal current fluctuation as the current verification result is a device that can be disconnected, then perform a disconnection operation on the power device with the abnormal current fluctuation as the current verification result.

[0064] All electrical equipment can be divided into equipment that can be disconnected and equipment that cannot be disconnected. For example, equipment that would affect navigation safety by disconnecting can be defined as equipment that cannot be disconnected. If the current verification result shows that the electrical equipment with abnormal current fluctuations is equipment that cannot be disconnected, then disconnection operations can be avoided to ensure the navigation safety of the ship.

[0065] In one embodiment of this application, the power distribution system is further configured to: control power equipment whose current verification result indicates abnormal current fluctuation to issue an alarm message.

[0066] Each piece of electrical equipment can be equipped with a corresponding buzzer or light. An alarm message can be issued by controlling the buzzer on the electrical equipment with abnormal current fluctuations to emit sound or the light to flash.

[0067] Please continue reading Figure 1 As shown, the power management system (PMS) of the power distribution system performs current verification based on fault point data (equipment information of electrical equipment associated with cables that have been detected to have abnormal temperatures). For electrical equipment with abnormal current fluctuations, an alarm will be issued accordingly. Among the electrical equipment with abnormal current fluctuations, for non-critical equipment, an emergency disconnection operation can be performed directly. For critical equipment, the corresponding backup equipment can be started first, and then the switchover can be performed to avoid affecting the navigation safety of the ship.

[0068] In one embodiment of this application, the cable heating monitoring system is located on the ship, and the power distribution system is further used to: obtain the current navigation status of the ship; determine whether the power equipment with abnormal current fluctuations in the current verification result is an allowable disconnection device in the current navigation status; if the power equipment with abnormal current fluctuations in the current verification result is an allowable disconnection device in the current navigation status, then perform a disconnection operation on the power equipment with abnormal current fluctuations in the current verification result; if the power equipment with abnormal current fluctuations in the current verification result is not an allowable disconnection device in the current navigation status, then do not perform a disconnection operation on the power equipment with abnormal current fluctuations in the current verification result.

[0069] A ship's navigation status can be, for example, slow sailing, anchored, high-speed sailing, or steady sailing. A pre-defined mapping table can be used to store the correspondence between each navigation status and the permissible disconnection devices for that status. The permissible disconnection devices for each navigation status are those whose disconnection will not affect the continuation of the corresponding navigation status. The permissible disconnection devices for the current navigation status can be obtained by querying this mapping table. Furthermore, electrical equipment with abnormal current fluctuations as determined by current verification can be compared with the permissible disconnection devices for the current navigation status to determine whether it is indeed a permissible disconnection device for that status.

[0070] In this embodiment of the application, since whether power equipment with abnormal current fluctuations as the current verification result is allowed to be disconnected is determined based on the current navigation status of the ship, it can be guaranteed that the execution of disconnection of power equipment will not affect the current navigation status of the ship.

[0071] In one embodiment of this application, the cable heating monitoring system further includes: a monitoring alarm system, which is connected to the main control box, for obtaining target identification information of the target temperature detection probe or the target cable intersection location corresponding to the target identification information of the target temperature detection probe from the main control box, and displaying prompt information at the corresponding position in the simulation diagram display interface according to the target identification information or the target cable intersection location.

[0072] The main control box can send information about abnormal temperature detection probes (such as the identification information of the temperature detection probes or the corresponding cable junction locations) to the monitoring and alarm system. The monitoring and alarm system has a display screen that can show a simulation diagram.

[0073] A mimic diagram (or mimic panel) is a graphical interface or physical panel used to visualize the operational status of industrial process systems (such as production processes, energy systems, and pipeline networks). It uses graphic symbols, colors, and dynamic indicators (such as lights and animations) to intuitively simulate the physical layout, equipment status, and technological processes of actual industrial systems, helping operators quickly understand system operation and perform monitoring and control.

[0074] The simulation display interface can simulate and display various power equipment and related cables, as well as temperature detection probes. Prompt information can be displayed at the target identification information or at the cable junction corresponding to the target cable junction or on the temperature detection probe.

[0075] Specifically, the prompts displayed at corresponding locations on the simulation diagram interface can be flashing elements; the monitoring and alarm system can also issue audible and visual alarms based on received target identification information or the location of target cable intersections. These prompts and alarms can help relevant personnel intuitively and efficiently grasp the location of cables experiencing abnormal temperatures, thereby enabling timely measures to prevent fires.

[0076] Please continue reading Figure 1 As shown, the main control box can send target identification information or target cable intersection location to the monitoring and alarm system. The monitoring and alarm system can generate a MIMIC diagram based on the received information and issue an alarm for abnormal temperature.

[0077] Figure 2 A flowchart of a cable heating monitoring method according to an embodiment of this application is shown. Please refer to... Figure 2 As shown, this method can be executed by the main control box of a cable heating monitoring system, which includes multiple temperature detection probes, a main control box, and a power distribution system. The method may include the following steps:

[0078] In step 210, temperature information reported by multiple temperature detection probes is acquired, with each temperature detection probe used to collect temperature information at a cable intersection location.

[0079] Temperature information at the respective cable junctions can be collected and reported using multiple temperature detection probes.

[0080] In step 220, if it is determined that the temperature information reported by the target temperature detection probe is abnormal based on the temperature information reported by each temperature detection probe, then the equipment information of the power equipment associated with the cable detected by the target temperature detection probe is determined according to the first correspondence, the second correspondence, and the third correspondence. The first correspondence is the correspondence between the probe's identification information and the cable intersection position; the second correspondence is the correspondence between the cable intersection position and the cable information; and the third correspondence is the correspondence between the cable information and the equipment information.

[0081] Based on the first, second, and third correspondences, it is possible to identify which electrical devices might be causing abnormal temperature readings from the target temperature detection probe, and obtain the device information for these devices. Device information may include the device's name or identifier; cable information may include the cable's name or identifier, and may further include the cable's model, material, dimensions, and other information.

[0082] In step 230, the equipment information of the power equipment associated with the cable detected by the target temperature detection probe is sent to the power distribution system so that the power distribution system can perform current verification on the corresponding power equipment based on the equipment information and perform a disconnection operation on the power equipment whose current verification result is abnormal current fluctuation.

[0083] The power distribution system can determine whether the current fluctuations of the power equipment are abnormal by performing current verification on the power equipment.

[0084] In one embodiment of this application, the device information of the power equipment associated with the cable detected by the target temperature detection probe is sent to the power distribution system, so that the power distribution system can perform current verification on the corresponding power equipment according to the device information, and perform a disconnection operation on the power equipment whose current verification result is abnormal current fluctuation. This includes: sending the device information of the power equipment associated with the cable detected by the target temperature detection probe to the power distribution system, so that the power distribution system can perform current verification on the corresponding power equipment according to the device information, and when a power equipment whose current verification result is abnormal current fluctuation is determined, the backup equipment corresponding to the power equipment whose current verification result is abnormal current fluctuation is activated according to the device type of the power equipment whose current verification result is abnormal current fluctuation as the target device type, and the power equipment whose current verification result is abnormal current fluctuation is disconnected.

[0085] In this application embodiment, if a power device with abnormal current fluctuation is found in the current verification result, and its device type is the target device type, the corresponding backup device needs to be activated first, and then the power device with abnormal current fluctuation is shut down urgently.

[0086] In one embodiment of this application, the device information of the power equipment associated with the cable detected by the target temperature detection probe is sent to the power distribution system, so that the power distribution system can perform current verification on the corresponding power equipment according to the device information, and perform a disconnection operation on the power equipment whose current verification result is abnormal. This includes: sending the device information of the power equipment associated with the cable detected by the target temperature detection probe to the power distribution system, so that the power distribution system can perform current verification on the corresponding power equipment according to the device information, and when it is determined that the power equipment whose current verification result is abnormal is a device that can be disconnected, performing a disconnection operation on the power equipment whose current verification result is abnormal.

[0087] In this embodiment of the application, the equipment can only be disconnected when there is an abnormal current fluctuation, thus ensuring the normal operation of the ship.

[0088] In one embodiment of this application, the device information of the power equipment associated with the cable detected by the target temperature detection probe is sent to the power distribution system, so that the power distribution system can perform current verification on the corresponding power equipment according to the device information, and perform a disconnection operation on the power equipment whose current verification result is abnormal current fluctuation, including: sending the device information of the power equipment associated with the cable detected by the target temperature detection probe to the power distribution system, so that the power distribution system can perform current verification on the corresponding power equipment according to the device information, perform a disconnection operation on the power equipment whose current verification result is abnormal current fluctuation, and control the power equipment whose current verification result is abnormal current fluctuation to issue an alarm message.
