Description

Technical Field

[0001] The present invention relates to the technical field of pleasure boats, in particular to a pleasure boat system. Background Art

[0002] With the booming tourism industry, cruise ship sightseeing has become an important way for many scenic spots to attract tourists. In particular, night cruise ships, with their unique charm, bring tourists a brand new sightseeing experience. However, the traditional cruise ship system faces many challenges in actual operation.

[0003] First, noise pollution has always been a major problem for night cruise operations. Traditional cruise ships often play music or commentary directly on board, which inevitably affects the quality of life of surrounding residents. Some scenic spots have tried to alleviate this problem by reducing the volume, but this has led to a decline in the tourist experience.

[0004] Secondly, the accuracy and synchronization of content playback is also a major challenge faced by existing technologies. Many cruise ship systems use preset time points to trigger content playback, but due to factors such as water flow and wind direction, the actual position of the cruise ship is often inconsistent with expectations, resulting in content playback not matching the actual attractions. Some systems try to solve this problem through manual operation, but this method not only increases labor costs, but is also prone to human errors.

[0005] In addition, the existing cruise systems generally lack flexibility and adaptability. Most systems can only provide a single sightseeing mode, and it is difficult to adjust the content and experience according to different time periods, weather conditions or special festivals. This fixed mode of operation is difficult to meet the growing personalized and diverse needs of tourists.

[0006] In terms of safety management, existing technologies also have obvious deficiencies. Most cruise ship systems rely only on manual observation and simple mechanical monitoring, lacking real-time and comprehensive safety monitoring methods. This not only increases safety risks, but also limits the scale and scope of night cruise operations.

[0007] Finally, the user interface of existing cruise systems is usually relatively simple and complicated to operate, which is not conducive to efficient operation and management by staff. This not only affects operational efficiency, but may also indirectly affect the quality of experience for tourists.

[0008] In view of the above problems, there is an urgent need for an innovative cruise system that can comprehensively address multiple challenges such as noise pollution, accurate content playback, flexible operation, safety management, and ease of use. Summary of the invention

[0108] Please refer to the attached Figure 1-9The present invention relates to a cruise system, and in particular to a comprehensive sound, light and electricity system for night cruise activities. The system innovatively solves a series of problems in night water tours, such as noise pollution, content synchronization, precise positioning, and diversified scene adaptation, through advanced technical means, and significantly improves the tourist experience and operational efficiency.

[0109] like Figure 1 As shown, the cruise ship system of the present invention comprises a control center module 1, a cruise ship module 2, a positioning module 3, an audio synchronization module 4 and a trigger control module 5. These modules work together to realize an efficient and intelligent cruise ship control system.

[0110] The control center module 1 is the core of the entire system, responsible for real-time monitoring of the cruise ship's location and equipment operating status, and remote management of cruise ship equipment and content playback. Preferably, the control center module 1 adopts a distributed architecture, including a main control server 11 and multiple backup servers 12 to ensure high availability of the system. The main control server 11 and the backup servers 12 are interconnected through a high-speed optical fiber network, and real-time data synchronization technology is used, so that when the main control server 11 fails, it can be seamlessly switched to the backup server 12 to ensure continuous operation of the system.

[0111] The cruise module 2 is connected to the control center module 1 via a wireless network, and is mainly used to receive control instructions and multimedia content, and perform corresponding operations and playback. In one embodiment of the present invention, the cruise module 2 includes a shipboard control unit 21 and a multimedia playback unit 22. The shipboard control unit 21 adopts an embedded system design, which has the characteristics of low power consumption and high reliability. The multimedia playback unit 22 supports audio and video files in multiple formats, such as MP3, WAV, MP4, AVI, etc., and has hardware decoding capabilities, which can smoothly play high-definition video content.

[0112] The positioning module 3 is electrically connected to the cruise ship module 2, and is used to collect the real-time location information of the cruise ship and send it to the cruise ship module 2. The present invention adopts the GPS and Beidou dual-system positioning technology, which significantly improves the positioning accuracy. Specifically, the positioning module 3 includes a GPS positioning unit 31 and a Beidou positioning unit 32. The GPS positioning unit 31 adopts multi-band receiving technology, which can simultaneously receive L1, L2 and L5 signals, thereby improving the positioning accuracy and anti-interference capability. The Beidou positioning unit 32 supports the reception of Beidou-2 and Beidou-3 satellite signals, further enhancing the reliability of the positioning system.

[0113] In order to fuse the positioning data of GPS and Beidou, the positioning module 3 of the present invention further includes a fusion processing unit 33. The fusion processing unit 33 uses a Kalman filter algorithm to fuse the positioning data of GPS and Beidou. The specific implementation of the Kalman filter algorithm is as follows:

[0114] Let the state vector be: X k =[x k ,y k ,v x,k ,v y,k ] T ,

[0115] where x k and k They represent the longitude and latitude at time k, respectively, and v x,k and v y,k They represent the speed in the longitude and latitude directions at time k respectively.

[0116] The state transfer equation is:

[0117] X k =FX k-1 +w k ,

[0118] Where F is the state transfer matrix:

[0119]

[0120] Δt is the sampling time interval, usually set to 1 second. k is process noise, which is assumed to obey a Gaussian distribution with a mean of 0 and a covariance matrix of Q.

[0121] The observation equation is:

[0122] Z k =HX k +v k ,

[0123] Among them, H is the observation matrix:

[0124]

[0125] v k For the observation noise, it is assumed to obey a Gaussian distribution with a mean of 0 and a covariance matrix of R.

[0126] The prediction steps of Kalman filter are:

[0127] X k|k-1 =FX k-1|k-1 ,

[0128] P k|k-1 =FP k-1|k-1 F T +Q,

[0129] The update steps are:

[0130] K k =P k|k-1 H T(HP k|k-1 H T +R) -1 ,

[0131] X k|k =X k|k-1 +K k (Z k -HX k|k-1 ),

[0132] P k|k =(IK k H)P k|k-1 ,

[0133] Among them, K k is the Kalman gain, P k |k is the state estimation error covariance matrix.

[0134] Through the above algorithm, the fusion processing unit 33 can effectively combine the positioning data of GPS and Beidou to provide more accurate location information. In practical applications, the positioning accuracy of the present invention can reach 0.5 meters, which is crucial for accurately triggering the content playback of the performance point.

[0135] The audio synchronization module 4 is electrically connected to the cruise ship module 2, and is used to receive the audio signal of the shore sound source and synchronously transmit it to the speaker on the cruise ship. In one embodiment of the present invention, the audio synchronization module 4 includes an audio collection unit 41, an audio processing unit 42, a wireless transmission unit 43 and an audio playback unit 44.

[0136] The audio acquisition unit 41 uses a high-sensitivity microphone array to effectively capture the environmental sound of the shore. The audio processing unit 42 uses digital signal processing (DSP) technology to perform noise reduction and gain processing on the collected audio signal. Specifically, the audio processing unit 42 uses an adaptive filtering algorithm to eliminate background noise and applies dynamic range compression technology to balance the volume.

[0137] The wireless transmission unit 43 adopts low-latency wireless audio transmission technology, such as aptX Low Latency codec technology, which can control the audio transmission delay within 40 milliseconds. The audio playback unit 44 adopts a high-fidelity speaker system to ensure the restoration of real environmental sound.

[0138] In order to ensure accurate synchronization between shore sound source collection and cruise ship playback, the audio synchronization module 4 of the present invention further includes a time synchronization unit 45. The time synchronization unit 45 uses the Network Time Protocol (NTP) for clock synchronization and uses timestamp technology to mark audio data packets. In this way, the system can control the time delay between shore sound source collection and cruise ship playback to within 50 milliseconds, which is almost imperceptible to the human ear.

[0139] The trigger control module 5 is electrically connected to the cruise ship module 2 and the positioning module 3, and is used to trigger the corresponding multimedia content playback according to the real-time location information of the cruise ship. In one embodiment of the present invention, the trigger control module 5 includes a region judgment unit 51, a content selection unit 52 and a playback control unit 53.

[0140] The area determination unit 51 determines whether to trigger content playback by comparing the real-time location information of the cruise ship with the preset geographical range of the performance point. The preset geographical range of the performance point is usually defined as a polygonal area, represented by a point array. The area determination unit 51 uses the ray method to determine whether a point is within the polygon. The specific algorithm is as follows:

[0141] Suppose the point to be judged is P(x,y), and the polygon vertex array is [(x1,y1),(x2,y2),...,(x n ,y n )].

[0142] 1. Initialize the number of intersection points count = 0,

[0143] 2. For each edge of the polygon (x i ,y i ) to (x i +1,y i+1 ),

[0144] a. If y is in y i and i+1 Between (including endpoints):

[0145] Calculate the x coordinate of the intersection point: x i ntersect=x i +(yy i )*(x i+1 -x i ) / (y i+1 -yi), if x intersect >x, then count increases by 1,

[0146] 3. If count is an odd number, the point is inside the polygon; otherwise, it is outside the polygon.

[0147] Through this algorithm, the area determination unit 51 can accurately determine whether the cruise ship has entered the preset performance point range.

[0148] The content selection unit 52 selects corresponding content from the pre-stored multimedia content library according to the trigger signal. The present invention adopts a hierarchical storage structure to organize multimedia content. Different operation modes (such as daytime mode, night mode, holiday mode, etc.) correspond to different content levels. This design can quickly locate and switch content suitable for the current scene.

[0149] The playback control unit 53 is responsible for controlling the multimedia devices on the cruise ship to play the selected content. In order to achieve smooth content transition, the playback control unit 53 adopts cross-fade technology. Specifically, when the cruise ship leaves the current performance point, the system will gradually reduce the volume of the current content to 0 within 3 to 5 seconds, and at the same time gradually increase the background music volume of the next performance point from 0 to a preset level within the same time. This smooth transition can effectively avoid abrupt sound switching and enhance the auditory experience of tourists.

[0150] Through the collaborative work of the above modules, the cruise system of the present invention can achieve accurate location perception, smooth content triggering and playback, and highly synchronized audio experience. This innovative technical solution not only significantly improves the immersion and interactivity of nighttime water tours, but also effectively solves the problem of noise pollution, providing tourists with a unique and unforgettable tour experience.

[0151] The trigger control module 5 of the present invention is a key component for achieving accurate content playback. Figure 2 As shown, the trigger control module 5 includes an area determination unit 51, a content selection unit 52 and a play control unit 53. These three units work together to ensure that the cruise ship plays appropriate content at the correct location, thereby providing tourists with a coherent and rich experience.

[0152] The main function of the area judgment unit 51 is to receive the real-time location information sent by the positioning module 3 and compare it with the preset geographical range of the performance point. In a preferred embodiment of the present invention, the preset geographical range of the performance point is defined as a polygonal area surrounded by a series of geographical coordinate points. In order to improve the judgment efficiency, the present invention adopts an improved ray method algorithm. The algorithm not only considers whether the point is within the polygon, but also introduces the concept of a buffer zone, so that the system can predict in advance that the cruise ship is about to enter the performance point range. Specifically, the algorithm expands 5-10 meters (the specific value can be dynamically adjusted according to the speed of the cruise ship) on the basis of the original polygon to form a buffer zone. When the cruise ship enters the buffer zone, the system starts to prepare related content, thereby achieving smoother content switching.

[0153] After receiving the trigger signal from the area judgment unit 51, the content selection unit 52 selects the content corresponding to the current performance point from the pre-stored multimedia content library. The system of the present invention adopts an intelligent content management strategy, which not only considers the location information, but also combines multi-dimensional factors such as time, weather, and tourist type. For example, on a clear summer evening, the system may choose more cheerful and lively background music; while on rainy days, it may choose more soothing and poetic music content. This intelligent content selection greatly enhances the personalization and adaptability of the tour experience.

[0154] The playback control unit 53 is responsible for controlling the multimedia devices on the cruise ship to play the selected content. In order to achieve a more natural and smooth content transition, the system of the present invention introduces a dynamic volume adjustment technology. Specifically, when the cruise ship enters a new performance point range, the system will gradually reduce the volume of the current content within 3 to 5 seconds, and gradually increase the volume of the new content. This transition time is the optimal value obtained through a large number of experiments, which can ensure the smoothness of content switching and will not cause content confusion due to excessive overlap time.

[0155] In addition, the playback control unit 53 also has real-time audio processing capabilities. In one embodiment of the present invention, the unit uses adaptive equalization technology to automatically adjust the frequency response of the audio according to the ambient noise level, ensuring that visitors can have a clear and comfortable listening experience in different environments. For example, when it is detected that the ambient noise is high, the system will appropriately increase the gain of the mid-frequency band (500Hz-2kHz) to improve voice clarity.

[0156] The system of the present invention further comprises a mode switching module 6, which is electrically connected to the control center module 1 and the cruise ship module 2. The introduction of the mode switching module 6 greatly improves the flexibility and adaptability of the system. Figure 3 As shown, the mode switching module 6 includes a mode receiving unit 61 and a mode executing unit 62 .

[0157] The mode receiving unit 61 is responsible for receiving mode switching instructions from the control center module 1. These instructions can be issued manually or automatically generated by the system according to preset rules. In a preferred embodiment of the present invention, the system supports multiple operating modes, including but not limited to day mode, night mode, holiday mode, essence mode and activity mode. Each mode corresponds to different content playback strategies and trigger logic.

[0158] For example, in daytime mode, the system may play more introductions to scenic spots and historical and cultural content; while in night mode, it may focus on music and light shows. Holiday mode may add some greetings and special effects to suit the occasion; essence mode may select the most popular performance spots for key displays, which is suitable for tourists with limited time. Event mode is reserved for special events (such as New Year's Day countdown, Chinese Valentine's Day, etc.), and the content and effects can be flexibly adjusted to match the theme of the event.

[0159] The mode execution unit 62 is responsible for adjusting various parameters and operation logic of the system according to the received mode switching instruction. This includes but is not limited to updating the judgment logic of the trigger control module 5, switching the content library of the content selection unit 52, adjusting the volume curve of the playback control unit 53, etc. The mode switching process is smooth and usually completed within 30 seconds to ensure that tourists will not feel a significant gap.

[0160] In order to further improve the intelligence and autonomy of the system, the mode switching module 6 of the present invention also includes a time sensing unit 63 and a mode automatic switching unit 64. The time sensing unit 63 obtains accurate time information in real time by synchronizing with the network time server. The mode automatic switching unit 64 automatically determines the current operating mode to be switched based on the time information and the preset rules.

[0161] For example, the system can be set to automatically switch from day mode to night mode at 18:00 every day, and switch to highlight mode at 21:00 (taking into account that some tourists may want to experience major attractions in a shorter period of time). During holidays, the system will automatically switch to holiday mode. This automatic switching mechanism greatly reduces the need for manual intervention and improves the efficiency and stability of system operation.

[0162] The system of the present invention further comprises a network management module 7, which is electrically connected to the control center module 1 and the cruise ship module 2. The network management module 7 plays a key role in ensuring the stable operation of the system. Figure 4 As shown, the network management module 7 includes a network monitoring unit 71 , a channel switching unit 72 and a data synchronization unit 73 .

[0163] The network monitoring unit 71 is responsible for real-time monitoring of the network connection status between the cruise ship and the control center. It evaluates the network quality by regularly sending heartbeat packets and detecting the response time. In a preferred embodiment of the present invention, the system sets multiple network quality thresholds. For example, when the packet loss rate exceeds 5% or the average response time exceeds 200ms, the system will issue a warning; when the packet loss rate exceeds 10% or the average response time exceeds 500ms, the system will trigger the channel switching mechanism.

[0164] The channel switching unit 72 will automatically switch to the backup communication channel when it detects that the network connection is interrupted or the quality is seriously degraded. The system of the present invention adopts multiple backup strategies, including 4G / 5G cellular networks, dedicated microwave links, and satellite communications. These channels are prioritized according to reliability and cost, and the system automatically selects the best available channel at the moment. For example, under normal circumstances, the system gives priority to the 5G network; when the 5G signal is poor, it will switch to the 4G network; if the cellular network is completely unavailable, satellite communication will be enabled as a last resort.

[0165] The data synchronization unit 73 is responsible for automatically re-establishing the connection and synchronizing the data after the network is restored. This process includes but is not limited to synchronizing the location history, playback records, system logs, etc. of the cruise ship. In order to improve the synchronization efficiency, the present invention adopts an incremental synchronization strategy, which only transmits the new data generated during the network interruption, thereby greatly reducing the data transmission volume and synchronization time.

[0166] It is worth mentioning that the network management module 7 of the present invention adopts advanced dual-band communication technology and supports both 4G and 5G networks. This not only improves the reliability of communication, but also reserves space for future technology upgrades. The system can dynamically switch between 4G and 5G according to network quality and data requirements, which not only ensures communication quality but also optimizes energy consumption.

[0167] Through the above detailed description, it can be seen that the cruise system of the present invention adopts innovative technical solutions in content triggering, mode switching and network management. These innovations not only improve the intelligence and reliability of the system, but also greatly enhance the experience quality of cruise tourism, providing tourists with a richer, smoother and more personalized sightseeing experience.

[0168] The system of the present invention further comprises a content management module 8, which is electrically connected to the control center module 1. The content management module 8 plays a core role in the entire cruise system, and is responsible for managing and optimizing the multimedia content library in the system. Figure 5 As shown, the content management module 8 includes a content storage unit 81 , a content update unit 82 and a content scheduling unit 83 .

[0169] The content storage unit 81 adopts a distributed storage architecture to store multimedia content in multiple servers. This architecture not only improves the security of data, but also significantly improves the speed of content access. In a preferred embodiment of the present invention, the content is classified and marked according to multiple dimensions such as type, theme, season, etc. For example, a video introducing historical buildings may be marked as historical culture, architecture, daytime mode, etc. This multi-dimensional marking system makes subsequent content retrieval and scheduling more efficient and accurate.

[0170] The content update unit 82 supports remote updating and pushing of new multimedia content. This process is incremental, and only newly added or modified content is transmitted, thereby greatly reducing the amount of data transmission. Preferably, the content update process uses an intelligent scheduling algorithm, and will select a period of time with low network load (such as early morning) for large-scale updates to avoid affecting daily operations. In addition, the content update unit 82 also has a version control function, allowing the system to quickly roll back to a previous stable version when a problem occurs.

[0171] The content scheduling unit 83 is responsible for dynamically adjusting the content playback order and combination according to different operation modes. This unit uses a machine learning algorithm to automatically optimize the content combination based on historical playback data, tourist feedback, time and season, etc. For example, the system may find that playing light folk background music in the summer evening can get better tourist feedback, so it will increase the playback ratio of such music in the corresponding period.

[0172] It is worth mentioning that the content management module 8 of the present invention also includes a content encryption unit 84. Considering that some multimedia content may involve copyright or sensitive information, the content encryption unit 84 uses the Advanced Encryption Standard (AES) algorithm to encrypt sensitive content. The encryption key is distributed to authorized cruise ship devices through a secure channel to ensure that only legitimate devices can decrypt and play these contents. This not only protects the rights and interests of content creators, but also prevents unauthorized access and use.

[0173] The system of the present invention further comprises a safety monitoring module 9, which is electrically connected to the control center module 1 and the cruise ship module 2. The safety monitoring module 9 plays a vital role in ensuring the safety of the cruise ship operation. Figure 6 As shown, the safety monitoring module 9 includes a parameter monitoring unit 91 , an abnormal alarm unit 92 and an emergency processing unit 93 .

[0174] The parameter monitoring unit 91 is responsible for real-time monitoring of various operating parameters of the cruise ship, including but not limited to speed, direction, tilt angle, battery power, etc. These parameters are collected by various sensors on the ship and transmitted to the parameter monitoring unit 91 at a high frequency (usually 10 times per second). In a preferred embodiment of the present invention, the parameter monitoring unit 91 uses data fusion technology to integrate data from multiple sensors to improve the accuracy and reliability of monitoring.

[0175] The abnormal alarm unit 92 is responsible for automatically sending an alarm signal to the control center when an abnormal parameter is detected. The system of the present invention sets a multi-level alarm threshold. For example, when the speed of the cruise ship exceeds 8 knots (about 14.8 kilometers per hour), the system will issue a yellow alarm; when the speed exceeds 10 knots (about 18.5 kilometers per hour), the system will issue a red alarm. Similarly, for the tilt angle, a yellow alarm is issued when it is above 5 degrees, and a red alarm is issued when it is above 10 degrees. These thresholds are based on a large amount of historical data and safety analysis, and can be dynamically adjusted according to actual operating conditions.

[0176] The emergency processing unit 93 is responsible for triggering the emergency system on the cruise ship in an emergency. This includes but is not limited to starting emergency lighting, releasing life-saving equipment, sending distress signals, etc. Preferably, the emergency processing unit 93 also has a remote control function, allowing the control center to take over part or all of the control of the cruise ship when necessary. For example, when it is detected that the cruise ship may collide with an obstacle, the control center can remotely adjust the course and speed of the cruise ship to avoid accidents.

[0177] It is particularly worth mentioning that the safety monitoring module 9 of the present invention adopts an advanced artificial intelligence algorithm that can predict potential safety risks. The algorithm is based on a deep learning model and predicts potential safety hazards that may occur in the short term (usually 5 to 10 minutes) in the future by analyzing historical operating data, current parameters and environmental factors (such as weather conditions, water flow conditions, etc.). For example, the system may predict that based on the current speed and direction, the cruise ship may enter an area with turbulent water in 10 minutes. In this case, the system will issue an early warning and recommend adjusting the route or reducing the speed. This forward-looking safety management greatly improves the safety of cruise ship operations.

[0178] Finally, the system of the present invention further comprises a user interaction module 10, which is electrically connected to the cruise ship module 2. The user interaction module 10 provides an intuitive and efficient system control interface for the cruise ship operator. Figure 7 As shown, the user interaction module 10 includes a display unit 101 , an input unit 102 and an adaptation unit 103 .

[0179] The display unit 101 is responsible for providing a graphical operation interface, and displays the position of the cruise ship, the content playback status and the system operation parameters in real time. In a preferred embodiment of the present invention, the display unit 101 adopts a customizable dashboard design. The operator can customize the interface layout and display content according to personal preferences and work requirements. For example, some operators may pay more attention to safety parameters, and they can put information such as speed, direction, and tilt angle in a prominent position on the display interface; while other operators may pay more attention to content playback, and they can put the currently playing content information and the preview of the next trigger point in the main position.

[0180] The input unit 102 is responsible for receiving the operator's manual control instructions and passing them to the corresponding functional modules. The system of the present invention supports multiple input methods, including touch screen operation, physical buttons, voice commands, etc. In particular, the system also supports gesture control, and the operator can complete common operations such as adjusting the volume and switching content through simple gestures. This diverse input method greatly improves the operational flexibility and efficiency of the system.

[0181] The introduction of the adaptation unit 103 enables the user interaction module 10 to support access from a variety of mobile devices, including smartphones, tablet computers, and laptops. The adaptation unit 103 uses responsive design technology to automatically adjust the interface layout according to the screen size and resolution of different devices. Furthermore, the adaptation unit 103 will dynamically adjust the data refresh frequency and the complexity of the displayed content according to the processing power of the device to ensure a smooth operating experience on various devices.

[0182] It is worth noting that the user interaction module 10 also integrates an intelligent recommendation function. Based on the machine learning algorithm, the system can analyze the operator's usage habits and current situation, and actively recommend the most likely operation options. For example, when the cruise ship approaches a new performance point, the system will automatically put the relevant content control options on the top, which is convenient for the operator to adjust quickly. This intelligent interface not only improves the operating efficiency, but also reduces the possibility of operating errors.

[0183] Through the above detailed description, it can be seen that the cruise system of the present invention adopts innovative technical solutions in content management, security monitoring and user interaction. These innovations not only improve the intelligence, safety and ease of use of the system, but also provide a comprehensive intelligent solution for the cruise tourism industry. The system of the present invention provides tourists with a safer, richer and more personalized sightseeing experience by integrating advanced technologies such as artificial intelligence, big data analysis, responsive design, etc., and also provides cruise operators with more efficient and reliable management tools. This all-round innovation is expected to promote the entire cruise tourism industry to develop in a more intelligent and humanized direction.

[0184] It should be noted that the above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc. made within the principles of the present invention should be included in the protection scope of the present invention.
