Description

Technical Field

[0001] The utility model belongs to the field of ship control. Specifically, the utility model relates to a marine monitoring and alarm system and a ship. Background Art

[0002] In the prior art, the whole-ship monitoring and alarm system is imperfect. In the cabins of a ship, various sensors and other devices are often set to collect the parameters of the corresponding equipment in the cabin in real time. For example, in the battery compartment, a BMS (battery management system) and a temperature sensor need to be set to collect the state parameters of the battery in real time, etc.

[0003] However, the existing whole-ship monitoring and alarm system often only monitors the parameters of a single cabin. For example, the comparative document (CN118423176A) discloses a ship diesel engine state monitoring and diagnosis system, which relates to the field of diesel engine state monitoring, including a data monitoring module, a preliminary diagnosis module, a gas analysis module, a working state monitoring module, a preliminary analysis and evaluation module, and a comprehensive analysis and evaluation module. The target ship diesel engine is monitored by multiple types of monitoring devices. This kind of parameter monitoring of the equipment in a single cabin can only understand the state of a single cabin, which is not conducive to the unified management and control of the whole ship and cannot meet the needs of the whole-ship monitoring. At the same time, the existing whole-ship monitoring and alarm system has a low safety level. When some components fail, the whole system will be paralyzed, resulting in the failure of monitoring, the inability to detect abnormalities in time, and thus bringing potential safety hazards.

[0017] Next, with reference to the drawings, through the description of the embodiments, the specific embodiments of the present utility model will be further described in detail. The purpose is to help those skilled in the art have a more complete, accurate, and in-depth understanding of the inventive concept and technical solution of the present utility model and to facilitate its implementation. It should be noted that the terms "first", "second", etc. used in this application are only for conveniently describing the technical solution to distinguish different components, and do not limit this application. To make the technical solution of the present utility model clearer, the present utility model is explained and illustrated through the following embodiments.

[0018] A marine monitoring and alarm system, as Figure 1 shown, the system includes a workstation (OS) unit, a data processing unit, a network bus unit, a sub-control unit, and an alarm device. Among them, the workstation unit is respectively connected to the data processing unit and the alarm device, and is used to monitor the parameters of the ship compartment and control the alarm device to give an alarm when abnormal parameters are found; the data processing unit is connected to the network bus unit, and is used to issue control instructions for data acquisition according to the monitoring needs of the workstation unit and send the acquired and processed data to the workstation unit after obtaining and processing the acquired data; the network bus is connected to the sub-control unit, and is used to realize data communication between the data processing unit and the sub-control unit; the sub-control units are respectively arranged in different ship compartments and are used to collect the parameters of different ship compartments according to the control instructions of the data processing unit. In this embodiment, the sub-control unit can select an SCU (system control unit), and the SCU is a commonly used existing technology for those skilled in the art. Specifically in implementation, the sub-control unit can flexibly select other controllers according to the actual situation.

[0019] In this embodiment, the ship's compartments include a battery compartment, an engine room, a cargo hold, a cockpit, a living quarters, etc. In the prior art, various sensors and other devices are often installed in these compartments to collect the parameters of the corresponding equipment in the compartments in real time. For example, the battery compartment needs to be equipped with a BMS (Battery Management System) and temperature sensors to collect the state parameters of the battery in real time. For the parameters of each compartment, this embodiment realizes the collection of the parameters of multiple compartments and uniformly integrates them in the workstation unit for unified monitoring, so as to facilitate the operator to understand the ship's state in real time and ensure the normal operation of the ship.

[0020] Specifically, the workstation unit of this embodiment includes a first workstation and a second workstation. Data is interconnected and they work synchronously between the second workstation and the first workstation. The second workstation is used to implement hot backup for the first workstation. The two workstations monitor each other. When one workstation fails, the other workstation can still work independently without being disturbed, thus ensuring the normal operation of the monitoring and alarm system of this application. In addition, both the first and second workstations include an industrial control computer and external devices. The external devices are connected to the industrial control computer and are used to implement human-computer interaction operations. The external devices that can be used in this embodiment include a display screen, a printer, a mouse, a keyboard, etc. Among them, the operator can set and query the parameters of the ship's compartments to be monitored through the mouse and keyboard, display the monitoring interface of the ship's compartments parameters through the display screen, and output the required ship's compartments monitoring parameters through the printer. The industrial control computer is respectively connected to the data processing unit and the alarm device. In this embodiment, when the industrial control computer monitors that a certain parameter exceeds its preset threshold, it can send an abnormal alarm signal to the alarm device, and then the alarm device reminds the operator through an audible and visual alarm device (such as a signal lamp, a buzzer, a voice broadcast device, etc.).

[0021] The data processing unit of this embodiment includes a first switch, a first controller, and a second switch. The first switch is connected between the workstation unit and the first controller and is used to realize data communication between the workstation unit and the first controller. For example, when the workstation unit sets the ship parameters to be monitored, the instructions issued by it can be sent to the first controller through the first switch. The second switch is respectively connected to the network bus unit, the workstation unit, and the first controller and is used to realize data communication between the network bus unit and the first controller or the workstation unit. The first controller is used to acquire and process data and output control instructions according to the commands of the workstation unit. Among them, due to the complex and diverse parameters of the ship cabin, there are some parameter data with simple forms that can be directly recognized by the industrial control computer. At this time, this type of data does not need to be processed by the first controller and can be directly sent to the industrial control computer through the second switch. Further, the data processing unit further includes a second controller. The second controller is respectively connected to the first switch, the second switch, and the first controller and is used to synchronously perform control and data processing with the first controller when the first controller is normal, monitor each other. At the same time, when the first controller fails, it replaces the first controller to ensure the normal operation of the system of this application.

[0022] In this embodiment, either the first controller or the second controller can adopt a programmable logic controller (PLC). The PLC can issue control instructions in real time to collect data from sensors and other devices, and at the same time support the processing of the collected data. Its powerful data processing ability is crucial for the entire monitoring and control process of this application.

[0023] In this embodiment, the data processing unit further includes a communication protocol expansion port, which supports data communication of protocols such as TCP / UDP. The port is respectively connected to the first switch and the second switch and is used to realize the communication between the data processing unit and third-party devices. On the one hand, it can support third-party devices such as smartphones to join the monitoring of ship parameters. On the other hand, it can form the monitoring of the parameters of other third-party devices, ensuring the high scalability of this application.

[0024] To form redundant backup of data to ensure the reliable security of data, the network bus unit set in this embodiment includes a first network bus and a second network bus. Either the first network bus or the second network bus is connected between the data processing unit and the sub-control unit. The design of the dual bus is used for redundant backup of the bus data. The design of the dual bus can make the data on the bus monitor and compare with each other, thereby ensuring the integrity and reliability of the data, and further improving the monitoring accuracy of the system of this application.

[0025] Each sub-control unit in this embodiment includes a digital I / O module, an analog I / O module, an RS485 communication interface module, an RS232 communication interface module, and a CAN communication module. The digital I / O module, the analog I / O module, the RS485 communication interface module, the RS232 communication interface module, and the CAN communication module are respectively connected to the network bus unit. The parameter types in different ship cabins are different, and the required data transmission speeds, communication methods, etc. are also different. Therefore, different signal input / output interfaces or communication interfaces are needed for parameter acquisition. Each module of the sub-control unit in this embodiment can be called according to different usage scenarios to collect the parameters of the ship cabin, which is sufficient to meet the requirements of various parameter transmissions and acquisitions, so that more ship parameter data can be monitored in this application.

[0026] Meanwhile, this application also proposes a ship, which includes the above-mentioned marine monitoring and alarm system.

Obviously, the specific implementation of the present invention is not limited by the above methods. As long as various non-substantive improvements are made by adopting the method concept and technical solution of the present invention; or without improvement, the above concept and technical solution of the present invention are directly applied to other occasions, they are all within the protection scope of the present invention.
