Description

Technical Field

[0001] The present invention relates to the field of ships, and in particular to an intelligent monitoring system for a ship engine room. Background Art

[0002] Ship intelligence has become an inevitable trend in the development of shipbuilding and shipping. With the development of shipping technology, the degree of ship informatization has gradually increased, and the requirements for ship system integration have become higher and higher. Based on the application experience of smart ships at home and abroad and the development direction of future ships, China Classification Society (CCS) formulated the "Smart Ship Specification" in 2015, and proposed that the smart ship integration platform should integrate the data of at least three systems: smart navigation, smart engine room, and smart energy efficiency management, to form a unified integrated platform for shipboard data and applications. The integrated platform can integrate the existing shipboard information management system and subsequent new systems to achieve comprehensive monitoring and intelligent management of ships, and realize data interaction with shore-based.

[0003] The various system data platforms of traditional ships have weak interactions with each other, resulting in relatively independent maintenance and management of existing big data integration platforms, with single functions and closed information. In addition, each system is designed independently, and the data modeling and transmission protocols are complex, making it difficult to integrate and interact.

[0004] Application number: 202110785415.4 A big data integration platform serving smart ships is proposed. The "integrated platform" is the basis, and the advanced information technology, real-time data transmission and aggregation, large computing capacity, remote control, sensors, etc. are used to realize the interactive connection between the engine room, the wheelhouse, and the shore base, and timely analyze and process the existing ship status, and the ship status can be sent to the shipping company in time. The technical staff of the shipping company will make reasonable suggestions to ensure that the losses and accidents are minimized, so as to better ensure the safety and efficiency of the ship during navigation.

[0005] However, the platform's information acquisition methods are not rich and detailed enough, and there is no relevant concept for data security. Summary of the invention

[0006] In order to achieve diversified engine room information acquisition and safe information transmission, the present invention proposes a ship engine room intelligent monitoring system, which includes: a data transceiver base station, a monitoring alarm node, an equipment data acquisition device, an environmental monitoring device, a control center, a data analysis center, and a relay station; the equipment data acquisition device is installed on the control cabinet or monitoring device of each equipment in the engine room, and it includes a pluggable interface for receiving data, and a data receiving module, a data processing module, and a data sending module are arranged in the shell of the equipment data acquisition device; the environmental monitoring device includes a monitoring camera, an infrared imager, and a smoke alarm; the equipment data acquisition device and the environmental monitoring device are both connected to the data transceiver base station arranged in the engine room through short-range wireless communication to achieve data intercommunication; the relay station is a space-based satellite or a shore-based relay station; the data analysis center is arranged in one of the control center, the space-based satellite, and the shore-based server; there are a number of monitoring alarm nodes, which are arranged on the inspection path of the ship, and the monitoring alarm node has a data transceiver module and an alarm module; the control center, the data transceiver base station, and the monitoring alarm node are in the same wireless local area network.

[0007] Preferably, each raw data collected by the equipment data acquisition device is first sent to the control center, which classifies and grades the raw data, and then sends the processed data to the relay station, which sends it to the data analysis center for comprehensive analysis, and then sends the analysis results to the control center via the relay station. The control center publishes the analysis results to the monitoring alarm node and the data transceiver base station, so that authorized personnel in the cabin, the control center, and the inspection office can quickly perceive whether the operation of each equipment in the cabin is normal or not.

[0008] Preferably, the data processing module of the equipment data acquisition device processes the received data including assigning numbers and encrypting the numbers, and the numbers facilitate the control center to distinguish the equipment from which the data comes, thereby facilitating the classification of the data.

[0009] Preferably, for the data acquisition device of each device, the encryption method of its data processing module is different, so different keys are required for decryption. These keys are sent together with the original data through the control center and relay station to the data analysis center for decryption and analysis.

[0010] Preferably, the monitoring alarm node is further provided with a sensing module, and the sensing module can realize NFC communication or Bluetooth communication with a mobile device, so as to facilitate the staff to quickly display the cabin data on the mobile device during inspection.

[0011] Preferably, the mobile device needs to be registered at the control center first and obtain the corresponding level of authority before it can obtain the cabin data information of the corresponding level and below during inspection.

[0012] Preferably, after receiving the data sent by the control center, the data analysis center analyzes whether the original data is within the normal threshold range in combination with the ship's AIS information and meteorological information, which is related to whether the monitoring alarm node issues an alarm.

[0013] Preferably, when the data analysis center analyzes that one or more parameters of the cabin are tending to be abnormal, it sends an early warning and suggestions to the control center, and the suggestions are based on the processing methods that match the dangerous situation and are stored in the data analysis center.

[0014] Preferably, after the information of the infrared imager and smoke alarm is transmitted to the control center, it is only represented by 0 or 1 to indicate normal or abnormal, and transmitted to the data analysis center, wherein the infrared imager is considered abnormal if it detects abnormally high or low temperature, and the smoke alarm is considered abnormal if it detects smoke.

[0015] In the present invention, equipment data acquisition devices are installed on each device in the engine room to collect the required operating data of each device, encrypt the collected data, and transmit the encrypted data to the local data transceiver base station through short-range wireless communication. The data transceiver base station then strengthens the signal and transmits it to the control center through the wireless local area network. The control center chooses to transmit the encrypted data to the data analysis center through a space-based or shore-based relay station. After decrypting the data, the data analysis center analyzes whether the operating data of each device in the engine room is within the normal threshold in combination with the ship's position, meteorological and other information, and encrypts the analysis results in the original encryption method and transmits them to the control center. The control center sends them to the monitoring alarm node for alarm or to the data transceiver base station for processing by nearby staff according to the corresponding situation. The system can be used by authorized staff to obtain cabin information at the control center, engine room, and inspection path, and real data will not be leaked during long-distance communication, thereby realizing diversified cabin information acquisition and secure information transmission.

[0019] like Figure 1 As shown, the ship engine room intelligent monitoring system of the present invention comprises: a data transceiver base station, a monitoring alarm node, an equipment data acquisition device, an environmental monitoring device, a control center, a data analysis center, and a relay station; the equipment data acquisition device is installed on the control cabinet or monitoring device of each equipment in the engine room, and it comprises a pluggable interface for receiving data, and a data receiving module, a data processing module, and a data sending module are arranged in the shell of the equipment data acquisition device; the environmental monitoring device comprises a monitoring camera, an infrared imager, and a smoke alarm, and the environmental monitoring device is used to prevent personnel from illegally entering the engine room and monitor the heat source condition of the engine room to warn of fire and leakage and other conditions; the equipment data acquisition device, The environmental monitoring devices all communicate with the data transceiver base station installed in the cabin through short-range wireless communication. The short-range wireless communication here can be WiFi, Bluetooth or other wireless communication methods; the relay station is a space-based satellite or a shore-based relay station. If the ship is sailing in the ocean, due to the curvature of the earth and the distance, a space-based satellite is selected as the relay station. If it is sailing in an inland river, it is better to choose a shore-based relay station; the data analysis center is set in the shore-based server; there are several monitoring and alarm nodes, which are set on the inspection path of the ship. The monitoring and alarm nodes have a data transceiver module and an alarm module; the control center, the data transceiver base station, and the monitoring and alarm nodes are in the same wireless local area network.

[0020] As a more specific implementation plan, the raw data collected by the equipment data acquisition device are first sent to the control center, which classifies and grades the raw data, and then sends the processed data to the relay station, which sends it to the data analysis center for comprehensive analysis, and then sends the analysis results to the control center via the relay station. The control center publishes the analysis results to the monitoring alarm node and the data transceiver base station, so that authorized personnel in the cabin, the control center, and the inspection office can quickly perceive whether the operation of each equipment in the cabin is normal or not.

[0021] As a more specific implementation scheme, the data processing module of the equipment data acquisition device processes the received data including assigning numbers and encrypting them. The numbers facilitate the control center to distinguish the equipment from which the data comes, thereby facilitating the classification of the data.

[0022] As a more specific implementation plan, for the data acquisition device of each device, the encryption method of its data processing module is different, so different keys are required for decryption. These keys and the original data are sent to the data analysis center through the control center and relay station in sequence for decryption and analysis, thereby enhancing the security of data transmission.

[0023] As a more specific implementation scheme, a sensing module is also provided in the monitoring alarm node, and the sensing module can realize NFC communication or Bluetooth communication with a mobile device, so that the cabin data can be quickly displayed on the mobile device when the staff conducts inspection.

[0024] As a more specific implementation scheme, the mobile device needs to first register at the control center and obtain the corresponding level of authority before it can obtain cabin data information of the corresponding level and below during inspection. For example, the cabin staff is set to level T2 and has access to information at levels T2 and below; the control center staff is set to level T1 and has access to information at levels T1 and below; the inspection personnel is set to level T3 and has access to information at levels T3 and below.

[0025] As a more specific implementation scheme, after receiving the data sent by the control center, the data analysis center analyzes whether the original data is within the normal threshold range in combination with the ship's AIS information and meteorological information, which is related to whether the monitoring alarm node issues an alarm.

[0026] As a more specific implementation plan, when the data analysis center analyzes that one or more parameters of the cabin are tending to be abnormal, it will issue warnings and suggestions to the control center. The suggestions are based on the processing methods that match the dangerous situation stored in the data analysis center, and the matching rules are based on similar parameters such as location, operating status, meteorological conditions, equipment model, etc.

[0027] As a more specific implementation scheme, after the information of the infrared imager and smoke alarm is transmitted to the control center, it is only represented by 0 or 1 to indicate normal or abnormal, and is transmitted to the data analysis center, where the infrared imager is considered abnormal if it detects abnormally high or low temperature, and the smoke alarm is considered abnormal if it detects smoke.

[0028] In the present invention, equipment data acquisition devices are installed on each device in the engine room to collect the required operating data of each device, encrypt the collected data, and transmit the encrypted data to the local data transceiver base station through short-range wireless communication. The data transceiver base station then strengthens the signal and transmits it to the control center through the wireless local area network. The control center chooses to transmit the encrypted data to the data analysis center through a space-based or shore-based relay station. After decrypting the data, the data analysis center analyzes whether the operating data of each device in the engine room is within the normal threshold in combination with the ship's position, meteorological and other information, and encrypts the analysis results in the original encryption method and transmits them to the control center. The control center sends them to the monitoring alarm node for alarm or to the data transceiver base station for processing by nearby staff according to the corresponding situation. The system can be used by authorized staff to obtain cabin information at the control center, engine room, and inspection path, and real data will not be leaked during long-distance communication, thereby realizing diversified cabin information acquisition and secure information transmission.
