Abstract

The present application relates to a Beidou-based ship timed sleep and wake-up method, system and device, which uses a watchdog timer to gently wake up the Beidou communication module in the ship's sleep state, periodically check whether the remote control end sends a command signal, and choose to continue to sleep or fully wake up the ship to perform tasks according to demand. This mechanism solves the problem of low energy utilization efficiency in normal operation of ships, allowing the ship to maintain a low power consumption state in the non-mission stage, significantly reducing energy consumption. In addition, a hierarchical strategy of light wake-up and full wake-up is adopted. When the Beidou communication module is lightly awakened, only the command signal is queried to avoid the waste of resources caused by directly waking up the entire ship system. This method optimizes the efficiency of energy allocation, extends the endurance of ships in long-term deployment, and at the same time improves the level of intelligent management of the system to ensure that the ship responds quickly to tasks when needed.

Description

Technical Field

[0001] The present application relates to the field of ship automatic control technology, and in particular to a Beidou-based ship timed sleep and wake-up method, system and device. Background Art

[0002] In areas where natural disasters such as floods and tsunamis occur frequently, ships serve as important tools for emergency monitoring and rescue and undertake critical tasks.

[0003] Normally, these ships are deployed in the target waters for a long time, and carry out real-time monitoring through a variety of sensor equipment. At the same time, when a disaster occurs, these ships also need to quickly switch to emergency rescue mode and participate in on-site rescue work.

[0004] If the ship maintains an all-weather operation status, this normal operation mode will have significant energy consumption problems, especially when no disaster occurs or monitoring is required, the ship's power system, navigation system and monitoring equipment are always in a high-power working state, resulting in low energy efficiency. For ships deployed for a long time, high energy consumption not only increases operating costs, but also puts higher requirements on the ship's continuous working ability. Once the energy reserve is insufficient, it will directly affect the effectiveness of monitoring and rescue work.

[0005] If the ship is only set to wake up at a specific time and stay in hibernation for the rest of the time, this fixed timed wake-up method can reduce energy consumption, but there is a problem of untimely response. Especially in the case of sudden disasters or emergency rescue needs, the ship cannot receive external instructions in time when it is not in the awakened state, which may lead to delayed response at critical moments and miss the best rescue opportunity. At the same time, the fixed wake-up cycle may not match the actual mission requirements, which may easily lead to the omission of important monitoring data or the delay of rescue work, and cannot meet the high requirements for real-time and flexibility in complex environments. Although this mode reduces energy consumption, it sacrifices the mission response speed, which has an adverse impact on the effectiveness of the mission and the overall operating efficiency of the ship.

[0006] That is, the current ship operation mode has the following technical problems: it is impossible to reduce energy consumption while ensuring the timeliness of mission response. Summary of the invention

[0045] In order to make the purpose, technical solution and advantages of the present application more clearly understood, the present application is further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present application and are not used to limit the present application.

[0046] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as those commonly understood by those skilled in the art to which this application belongs. The terms used in the specification of this application are only for the purpose of describing specific embodiments and are not intended to limit this application.

[0047] It should be noted that the reference to "embodiment" in this document means that the specific features, structures or characteristics described in conjunction with the embodiment may be included in at least one embodiment of the present invention. The presentation of the phrase at various locations in the specification does not necessarily refer to the same embodiment, nor is it an independent or alternative embodiment that is mutually exclusive with other embodiments.

[0048] The following will describe the implementation of the present invention in detail with reference to the accompanying drawings in the embodiment diagram of the present invention.

[0049] In one embodiment, Figure 1 As shown, the embodiment of the present application provides a Beidou-based ship scheduled sleep and wake-up method, including the following processing steps S12-16:

[0050] S12, after the watchdog timer times out, gently wake up the Beidou communication module; during the watchdog timer timing, the ship is in a dormant state.

[0051] It can be understood that the timed wake-up function of the ship is realized through the watchdog timer. During the timing cycle, the ship is in a low-power sleep state. When the watchdog timer ends (times out), the Beidou communication module is gently awakened. Light wake-up means that only the Beidou communication module is awakened, while other systems of the ship remain in sleep state to minimize energy consumption.

[0052] Specifically, in this ship system, the watchdog timer is designed as a key module for timed wake-up. The watchdog timer can be integrated in the ship's main control chip or as an independent low-power hardware module. It can be timed by a low-frequency clock source (such as an internal oscillator or an external crystal oscillator) to ensure that it can still maintain low-energy operation in sleep state.

[0053] Initialization settings: When the system is powered on, the watchdog timer is initialized and configured, including setting the timing period (for example, 25 minutes) and defining the processing behavior after the timeout trigger (gently waking up the Beidou communication module). The timing period can be flexibly adjusted through software to meet the needs of different mission scenarios. Timing process: When the system enters the dormant state, the watchdog timer runs independently and is not affected by other modules; during the timing period, it continues to record time, and other modules (such as the Beidou communication module and the power system) are in low power mode, completely stop working or run in standby mode.

[0054] Timeout trigger: Once the watchdog timer's timing cycle ends (i.e. a timeout event occurs), it will generate an interrupt signal or trigger signal to notify the main control unit to wake up the Beidou communication module. The wake-up signal directly acts on the Beidou communication module through the hardware circuit, causing it to switch to the working mode and start the query of the task signal. Reset and loop operation: If the queried task signal is empty, the watchdog timer will be reset and the next round of timing cycle will be restarted. This loop operation mechanism ensures that the system can enter the light wake-up state regularly, balancing the timeliness of task response and the minimum energy consumption.

[0055] S14, query whether the remote control terminal has sent a command signal; the task command is a monitoring task signal or an emergency rescue signal.

[0056] It can be understood that after the Beidou communication module is gently awakened, it connects to the remote control terminal through the communication channel to query whether there are any mission instructions. Mission instructions mainly include two categories: monitoring mission signals and emergency rescue signals. The former is used for environmental parameter monitoring, and the latter is used for disaster emergency response.

[0057] Specifically, after the Beidou communication module is gently awakened, it will start its built-in communication program and enter the command query mode. Module initialization: In the initial stage of gentle awakening, the Beidou communication module first completes the hardware initialization, including activating its communication chip, configuring the working frequency band and protocol stack, and turning on the core functions in a low-power state. This step ensures that the Beidou communication module can run basic communication tasks while saving energy as much as possible. Establish a short-term data link: Through the communication channel of the Beidou satellite navigation system, the Beidou communication module establishes a short-term data link with the remote control terminal. The link adopts a low-latency, high-stability transmission protocol (such as the Beidou RDSS communication protocol) to support reliable data exchange in a short period of time; the link establishment process includes steps such as channel search, synchronization calibration and authentication handshake.

[0058] Sending query request: After the data link is established, the Beidou communication module will automatically send a standardized query command request packet to the remote control end. The request packet carries the ship's identification information (such as equipment number or task identification) to ensure that the remote control end can identify and process the ship's mission requirements. Receiving command signal: After sending the query request, the Beidou communication module enters the passive monitoring state and obtains the latest task command of the remote control end by decoding the received return signal; the command signal can be encrypted (such as symmetric key or public key encryption mechanism) to ensure data security. The Beidou communication module uses the built-in decoding algorithm to decrypt the data and perform integrity check on the command content. Short-term link disconnection: After completing the reception and processing of the command signal, in order to save energy consumption, the module immediately disconnects the short-term data link with the remote control end and caches the command to the internal memory for use by the subsequent task execution module.

[0059] Through this series of operations, the Beidou communication module can quickly and accurately obtain task instructions from the remote control end in a light wake-up state while minimizing energy consumption.

[0060] S16, if the command signal is not found, reset the watchdog timer and keep in sleep mode; if the command signal is found, wake up the ship completely and execute the command.

[0061] It can be understood that the subsequent status of the ship is determined according to the query result. If no task instruction is found, the Beidou module turns off the communication function and returns to the sleep state, and resets the watchdog timer and restarts the timing. The entire ship system maintains a low power consumption state and waits for the next light wake-up cycle.

[0062] If the mission instruction is queried, the subsystems of the ship will be fully awakened, and specific monitoring or rescue tasks will be performed. Specifically, after receiving the mission instruction signal, the control unit will identify the mission type (monitoring or rescue) through system logic analysis, and issue a full awakening instruction to activate the subsystems of the ship to get out of the dormant state. First, wake up the power system of the ship, start the motor or propulsion device, and provide the ship with movement capabilities. In the monitoring mission, the power system operates in low-power mode to ensure that the ship moves stably to the monitoring area. In the rescue mission, the power system enters high-power mode to ensure a quick response to the designated rescue location. At the same time, the navigation system is started synchronously, the positioning module (Beidou) and the heading control module are turned on, and the path and position information are calculated in real time to ensure that the ship reaches the target area accurately.

[0063] Depending on the type of mission, the control unit will further activate related functional modules. In monitoring missions, the sensor module is activated to collect environmental parameters, such as collecting data based on marine environmental indicators, meteorological indicators and other comprehensive indicators, and transmitting the data to the remote control end in real time. In rescue missions, the control unit can activate equipment such as robotic arms, signal lights or sound and light alarms to assist in completing rescue goals, or assist in rescue by throwing lifebuoys, etc., and the crew on the ship can also operate and assist manually.

[0064] In addition, in the previous light wake-up phase, the Beidou communication module operates in low-power mode. In the full wake-up phase, the Beidou communication module needs to switch to a fully activated state, so as to have higher data transmission capabilities to support complex communication needs such as task progress feedback and dynamic command reception. Through this step-by-step, on-demand wake-up method, the system can maximize energy efficiency while meeting task execution requirements.

[0065] In the above-mentioned Beidou-based ship timed sleep and wake-up method, the Beidou communication module is lightly awakened by using the watchdog timer in the ship's sleep state, and the remote control end is periodically checked to see whether it sends a command signal, and the ship is selected to continue to sleep or fully wake up according to demand to perform tasks. Through the mechanism of timed sleep and wake-up, the problem of low energy utilization efficiency of ships in normal operation is solved, so that the ship can be in a low power consumption state in the non-task stage, significantly reducing unnecessary energy consumption. Furthermore, a hierarchical wake-up strategy of light wake-up and full wake-up is adopted. When the watchdog timer periodically lightly wakes up the Beidou communication module, only the command signal is queried, avoiding the additional resource waste that may be caused by directly waking up the entire ship system. This strategy not only optimizes the allocation efficiency of ship energy, greatly extends the ship's endurance in long-term deployment, but also improves the system's intelligent management level, ensuring that tasks can be responded to quickly when needed.

[0066] In one embodiment, in the Beidou-based ship timing sleep and wake-up method, if a monitoring task signal is queried in step S14, the ship is fully awakened and the instruction is executed in step S16, specifically:

[0067] Analyze the monitoring mission signal; the monitoring mission signal includes the monitoring area and monitoring indicators; navigate to the monitoring area, collect data according to the monitoring indicators, and send it to the remote control end through the Beidou communication module.

[0068] It can be understood that the control unit parses the monitoring task signal and extracts the monitoring area and monitoring indicators.

[0069] The monitoring area is used to identify the target location that the ship needs to reach. This target location can be the ship's permanent dormant site, that is, a fixed monitoring point where the ship usually moors and hibernates, so that environmental monitoring can be carried out directly without the need for long-distance sailing. In addition, the target location can also be a specific monitoring point located in other areas. The ship needs to sail to this area according to the mission instructions to carry out the monitoring mission. The ship can accurately reach the monitoring area through the linkage of the navigation and power systems to ensure the smooth execution of the monitoring mission.

[0070] Monitoring indicators are used to indicate the type of data that needs to be collected. Specifically, monitoring indicators may include marine environmental indicators, meteorological indicators and other comprehensive indicators; marine environmental indicators may include sea level height (key indicators for tsunamis and high tides), wave height and frequency (storm surge related indicators), sea water temperature (warning of possible tsunamis or marine meteorological changes), sea water salinity (analysis of tidal dynamics or abnormal ocean currents) and underwater pressure (facilitating the rapid detection of potential tsunami signals); meteorological indicators may include wind speed and direction (used to determine whether there are strong winds or typhoons), air pressure (abnormal air pressure is usually a precursor to the formation of typhoons or storms), air temperature and humidity (determining weather conditions) and precipitation (used to warn of possible flooding or flood risks); comprehensive indicators may include ocean current speed and direction (used to predict abnormal tidal currents and disastrous marine activities), seismic wave signals (to detect earthquakes that may trigger tsunamis), visibility (reference value for navigation and rescue missions) and wave period (used to assess the stability of waves and whether there are destructive fluctuations).

[0071] Specifically, during the execution of the monitoring task, the ship starts the corresponding sensor module to collect data according to the monitoring indicators. For the above-mentioned marine environmental indicators, the sea level gauge, wave sensor, underwater pressure sensor, and seawater temperature and salinity sensor can be activated to obtain relevant data in real time. For meteorological indicators, the wind speed and direction sensor, air pressure sensor, temperature and humidity sensor and precipitation monitoring module can be started to complete the meteorological data collection. Regarding the monitoring of comprehensive indicators, multi-functional sensors can be used to collect data such as ocean current speed and direction, seismic wave signals, visibility, and wave period. All collected data is sent to the remote control end in real time through the Beidou communication module. The communication module transmits in high-speed mode to ensure data integrity and real-time performance, and supports the remote control end to send dynamic instructions to optimize the monitoring task process or adjust the collection strategy.

[0072] The above-mentioned Beidou-based ship timed sleep and wake-up method realizes the analysis and response of monitoring task signals. The ship can automatically navigate to the designated monitoring area and accurately collect marine environment, meteorological and comprehensive indicator data according to preset monitoring indicators, and transmit them to the remote control end in real time through the Beidou communication module, ensuring the comprehensiveness, real-time and accuracy of the monitoring data. At the same time, it supports dynamic adjustment of tasks, improves the ship's autonomous monitoring capabilities and flexibility in dealing with complex environments.

[0073] In one embodiment, in the Beidou-based ship timing sleep and wake-up method, if an emergency rescue signal is queried in step S14, the ship is fully awakened and the instruction is executed in step S16, specifically:

[0074] Parse emergency rescue signals; emergency rescue signals contain distress locations and safe locations.

[0075] It can be understood that the control unit first analyzes the emergency rescue signal content and extracts the distress location and safe location information. The distress location is used to guide the ship to the area where the rescued person is located, and the safe location is the safe berthing point to be reached after the rescue is completed.

[0076] According to the current position of the ship and the distress location, the optimal route is calculated and the ship sails along the optimal route.

[0077] It can be understood that during the emergency rescue process, the system first determines the current geographic location and distress location of the ship by receiving and parsing the emergency rescue signal. After parsing the signal, the system extracts the coordinate information of the current location of the ship and compares it with the coordinates of the distress location. Through this comparison, the system can clearly understand the distance and azimuth relationship between the two. Next, the system uses the navigation module and the Beidou positioning module to calculate the optimal route. The navigation module generates an optimal route based on multiple factors such as the sea conditions, channel information, weather conditions, etc. between the current ship position and the distress location, combined with the principles of the shortest voyage and the safest channel. In addition, the Beidou positioning module provides real-time positioning information to ensure that the ship can accurately track the route and make necessary adjustments.

[0078] After calculating the optimal route, the system can instruct the ship to follow this path. The navigation module continuously updates the ship's position and adjusts the route based on real-time data to respond to possible emergencies, such as climate change or waterway obstacles, to ensure that the ship can safely reach the target area by the fastest route. The combination of emergency signal analysis, real-time positioning and intelligent route calculation greatly improves rescue efficiency and ensures that the ship can reach the distress area in a timely and safe manner for rescue.

[0079] When the distance between the ship and the distress location reaches the preset proximity threshold, it switches to precise navigation mode to confirm the specific location of the person to be rescued; the precise navigation mode uses cameras, infrared sensors or radars to assist in the search.

[0080] It is understood that when the distance between the ship and the distress location approaches the preset threshold, the system will automatically switch to the precise navigation mode. This process is done by monitoring the distance between the ship and the distress location in real time and comparing it with the set proximity threshold. Once the ship approaches this distance, the system will activate the precise navigation mode, which no longer relies solely on the traditional navigation path, but uses more accurate means to confirm the specific location of the person to be rescued.

[0081] Precision navigation mode relies on the coordinated work of multiple auxiliary devices. Infrared sensors can detect temperature differences and help identify rescued personnel, which can clearly identify the target location even in bad weather or night conditions. Radar systems can further enhance search capabilities, especially in low visibility conditions, by transmitting and receiving electromagnetic waves to determine the location and movement of objects.

[0082] At the same time, if there are staff on board, they can manually confirm the specific location of the person to be rescued through the images transmitted by the real-time monitoring camera or the data fed back by the sensor. This confirmation process can improve the accuracy of the search and avoid errors. In addition, during the search process, the staff can also prepare rescue equipment such as lifeboats, ropes or first aid kits according to the actual situation to ensure that once the person to be rescued is located, the rescue operation can be quickly launched.

[0083] This precise navigation mode combines a variety of advanced sensing technologies and human assistance, allowing the ship to locate the rescued more efficiently and accurately when approaching the distress location, ensuring that the rescue process is swift and accurate.

[0084] After the rescue is completed, sail to a safe location.

[0085] After the rescue is completed, the control unit re-plans the route according to the safe location information in the emergency rescue signal, and the navigation system and power system work together to guide the ship to a safe location. During this process, the Beidou communication module maintains two-way communication with the remote control terminal throughout the process, reporting the rescue progress in real time and receiving dynamic instructions. The staff cooperates with the system operation according to the mission requirements to ensure that the ship arrives safely at a safe location and completes the entire rescue mission.

[0086] The above Beidou-based ship timed sleep and wake-up method realizes efficient response and precise positioning of ships in emergency rescue scenarios through the organic combination of emergency signal analysis, real-time positioning, intelligent route calculation and precise navigation mode. It uses a variety of sensing technologies to work together, not only to quickly plan the optimal route and improve rescue efficiency, but also to switch to precise navigation mode when approaching the target to ensure that the specific location of the rescued person is accurately confirmed. In addition, through the linkage operation of the system and manual operation, the flexibility and safety of the rescue are further improved. After the rescue is completed, it can also quickly and safely sail to the predetermined safe position, significantly enhancing the ship's autonomous rescue capabilities and task completion efficiency in emergency situations.

[0087] In one embodiment, the above-mentioned Beidou-based ship timed sleep and wake-up method also includes: when the night trigger time arrives, the ship is automatically and completely awakened, the watchdog timer is suspended, and the night task is executed; the night task can be pre-set; after the night task is completed, the watchdog timer is resumed.

[0088] It can be understood that under normal circumstances, the ship enters sleep mode, and the sleep and wake-up operations are managed by the watchdog timer to save energy. In sleep mode, other systems of the ship are in a low power consumption state to reduce unnecessary energy consumption.

[0089] To perform nighttime missions, the ship's control system will automatically wake up the ship according to a pre-set nighttime trigger time. This time can be set based on the time zone of the ship's location or the time provided by the BeiDou satellite system. Once the pre-set trigger time is reached, the ship will fully wake up and suspend the watchdog timer. This operation ensures that the ship can complete its scheduled mission without being restricted by sleep mode.

[0090] In particular, since the crew is resting or tired at night, it is difficult to detect possible dangers or weather changes around the sea area in time, so ships need to perform environmental monitoring tasks autonomously during this period. Real-time perception and recording of sea conditions through intelligent systems can make up for the shortcomings of manual monitoring and ensure timely acquisition of key environmental information in the absence of human supervision or slow response, thereby preventing potential risks.

[0091] Night missions can include operations such as environmental monitoring. For example, ships can conduct real-time monitoring based on marine environmental indicators, meteorological indicators and other comprehensive indicators, or they can only monitor surrounding meteorological conditions, such as wind speed, wind direction, wave height, temperature, etc. Through sensors and Beidou satellite communication systems, ships upload the collected data to the onshore control system to ensure timely access to environmental information. This approach can greatly improve safety and decision support at night.

[0092] In addition to environmental monitoring, ships can also set other nighttime tasks. For example, ships can perform health checks on the hull, such as detecting whether the ship has faults or abnormal vibrations, automatically detect and record battery status, perform self-checks on the communication system, or send data updates to the shore system. Navigation checks in low-power mode can also be performed at night to ensure the accuracy of the ship's position and heading information, or automatic cleaning tasks can be performed to ensure the normal operation of ship equipment.

[0093] After completing these tasks, the ship will resume the watchdog timer and re-enter the sleep state after the task is completed (it can also be preset to re-enter the sleep state at a specific time), continuing to save energy and maintain stable operation of the system. In this way, the ship can perform important monitoring and maintenance at night, ensuring safe and efficient navigation, while avoiding fatigue of the staff.

[0094] In one embodiment, the above-mentioned Beidou-based ship timed sleep and wake-up method, when the ship is in sleep state, also performs lightweight monitoring to obtain lightweight monitoring data; when the lightweight monitoring data exceeds the set threshold, the ship is automatically fully awakened, the watchdog timer is suspended, and emergency tasks are performed; emergency tasks include sending risk perception signals to the remote control end, and continuously collecting environmental data and sending it to the remote control end.

[0095] It can be understood that the Beidou-based ship timed sleep and wake-up method further optimizes the functions in the sleep state. After the ship enters the sleep mode, it is not necessary to completely shut down all functions, but to keep the operation of the lightweight monitoring module. The lightweight monitoring module usually includes sensors or devices with low power consumption, which are used to continuously monitor key indicators of the ship and the surrounding environment, such as water temperature, water flow rate, wave height, wind speed, wind direction and other environmental data, or the key parameters of the ship itself, such as tilt angle, battery power and vibration conditions.

[0096] When the lightweight monitoring module detects that the monitoring data exceeds the set threshold (such as a sudden increase in wind speed, abnormal changes in water flow, or the hull tilt angle exceeds the normal range), the system will determine that there is a potential risk in the current situation. At this time, the ship will automatically wake up completely, suspend the operation of the watchdog timer through the control system, and enter the emergency state to quickly respond to the risk.

[0097] The specific implementation of emergency tasks includes:

[0098] 1. Send risk perception signals: The Beidou communication module of the ship will immediately send risk perception signals to the remote control end through the Beidou satellite system. The content includes the currently monitored over-limit data and its specific time, so that the remote control end can receive timely alarms.

[0099] 2. Continuous collection and transmission of environmental data: In the awake state, the ship will activate more accurate environmental sensors and equipment to collect detailed environmental data (such as accurate wind speed, wave height, current changes) and hull status data (such as vibration frequency, battery status) in real time. The collected data will be continuously transmitted to the remote control terminal through the Beidou communication module to support the decision-making of the shore team.

[0100] 3. Perform other emergency operations: Depending on the specific configuration of the ship, emergency tasks may also include activating sound and light alarm equipment, adjusting the ship's attitude to reduce risks (such as changing the anchor position or stabilization system parameters), or providing necessary auxiliary information to the crew.

[0101] After the emergency mission is completed, the ship will determine whether it can return to normal sleep mode based on the feedback from the remote control terminal or the mission preset. If the risk is eliminated and no further operation is required, the ship will restart the watchdog timer and enter the next round of sleep management process.

[0102] In the above-mentioned Beidou-based ship timed sleep and wake-up method, the ship still has a certain risk perception and emergency response capability in the sleep state, which greatly improves the safety and intelligence level of the ship, especially in unmanned operation or extreme environments. It can effectively ensure the stable operation of the system.

[0103] In one embodiment, in the above-mentioned Beidou-based ship timed sleep and wake-up method, the timeout period of the watchdog timer is set to any value within 20 to 30 minutes.

[0104] In one embodiment, in the above Beidou-based ship timed sleep and wake-up method, during an emergency rescue process, the preset proximity threshold is set to any value within a range of 50 meters to 200 meters.

[0105] It should be understood that although Figure 1 The steps in the flowchart are shown in sequence as indicated by the arrows, but these steps are not necessarily executed in the order indicated by the arrows. Unless otherwise specified in this document, there is no strict order restriction for the execution of these steps, and these steps can be executed in other orders. Moreover, Figure 1 At least part of the steps may include multiple sub-steps or multiple stages. These sub-steps or stages are not necessarily executed at the same time, but can be executed at different times. The execution order of these sub-steps or stages is not necessarily sequential, but can be executed in turn or alternately with other steps or at least part of the sub-steps or stages of other steps.

[0106] In one embodiment, a Beidou-based ship timing sleep and wake-up system is provided, comprising: a control module, used to gently wake up the Beidou communication module after the watchdog timer times out; during the timing of the watchdog timer, the ship is in a sleep state;

[0107] Beidou communication module, used to query whether the remote control terminal has sent a command signal; the task command is a monitoring task signal or an emergency rescue signal;

[0108] The control module is also used to reset the watchdog timer and maintain a dormant state if no command signal is found;

[0109] The monitoring task module is used to fully wake up the ship and execute the command if the monitoring task signal is queried;

[0110] The emergency rescue module is used to fully wake up the ship and execute instructions if an emergency rescue signal is queried.

[0111] The above-mentioned Beidou-based ship timed sleep and wake-up system uses the watchdog timer to lightly wake up the Beidou communication module when the ship is in sleep mode, periodically checks whether the remote control terminal sends a command signal, and chooses to continue to sleep or fully wake up the ship to perform tasks according to needs. Through the mechanism of timed sleep and wake-up, the problem of low energy utilization efficiency of ships in normal operation is solved, so that the ship can be in a low power consumption state in the non-task stage, significantly reducing unnecessary energy consumption. Furthermore, a hierarchical wake-up strategy of light wake-up and full wake-up is adopted. When the watchdog timer periodically lightly wakes up the Beidou communication module, only the command signal is queried, avoiding the additional resource waste that may be caused by directly waking up the entire ship system. This strategy not only optimizes the allocation efficiency of ship energy, greatly extends the endurance of ships in long-term deployment, but also improves the intelligent management level of the system, ensuring that tasks can be responded to quickly when needed.

[0112] In one embodiment, the Beidou-based ship timing sleep and wake-up system further includes:

[0113] Lightweight monitoring module, used for lightweight monitoring when the ship is in dormant state, and obtaining lightweight monitoring data;

[0114] Lightweight wake-up module, used to automatically and fully wake up the ship when the lightweight monitoring data exceeds the set threshold;

[0115] The control module is also used to suspend the work of the watchdog timer;

[0116] The emergency module is used to perform emergency tasks; emergency tasks include sending risk perception signals to the remote control terminal and continuously collecting environmental data and sending it to the remote control terminal.

[0117] For the specific definition of the Beidou-based ship timed sleep and wake-up system, please refer to the definition of the Beidou-based ship timed sleep and wake-up method above, which will not be repeated here. Each module in the above-mentioned Beidou-based ship timed sleep and wake-up system can be implemented in whole or in part by software, hardware and a combination thereof. The above-mentioned modules can be embedded in or independent of the processor in the computer device in the form of hardware, or can be stored in the memory of the computer device in the form of software, so that the processor can call and execute the operations corresponding to the above modules.

[0118] In one embodiment, a computer device is provided, including a memory and a processor, wherein the memory stores a computer program, and when the processor executes the computer program, the following steps are implemented:

[0119] After the watchdog timer times out, the Beidou communication module is gently awakened; during the watchdog timer timing, the ship is in a dormant state;

[0120] Check whether the remote control terminal has sent a command signal; the task command is a monitoring task signal or an emergency rescue signal;

[0121] If no command signal is found, the watchdog timer is reset and the system remains in sleep mode; if a command signal is found, the system fully wakes up the ship and executes the command.

[0122] It can be understood that in addition to the memory and processor involved above, the above-mentioned computer device also includes other software and hardware components not listed in this specification. The specific components can be determined according to the model of the specific computer device in different application scenarios, and this specification will not list them one by one in detail.

[0123] In one embodiment, when the processor executes the computer program, it can also implement the steps or sub-steps added in each embodiment of the above-mentioned Beidou-based ship timed sleep and wake-up method.
