[0048] The embodiments of the present invention provide a system and method for safely rescuing ship personnel, which are used to solve the technical problems that video surveillance methods have blind spots and lags, and cannot timely track and locate ship personnel in danger of falling into the water, which easily leads to missing the best rescue opportunity.

[0049] In order to make the purpose, features and advantages of the present invention more obvious and easy to understand, the technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. Obviously, the embodiments described below are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0050] See also Figure 1 , Figure 1 A structural block diagram of a safety rescue system for ship personnel provided by an embodiment of the present invention.

[0051] The present invention provides a safety rescue system for ship personnel, comprising a positioning module, a control module, a rescue dispatching module and a plurality of personnel equipment connected in communication;

[0052] The positioning module 101 is used to respond to the positioning signal sent by any personnel equipment, locate the equipment position of the personnel equipment and upload it to the control module and the rescue dispatch module respectively;

[0053] The control module 102 is used to determine whether the ship personnel are in a state of need for rescue according to the equipment position and the lowest ship side position; if so, send a first rescue instruction to the rescue dispatch module;

[0054] The rescue dispatching module 103 is used to dispatch rescue equipment from the ship and move it to the equipment location to perform rescue actions when receiving the first rescue instruction and the equipment location.

[0055] In an embodiment of the present invention, a ship personnel rescue system includes a positioning module, a control module, a rescue dispatching module and a plurality of personnel equipment that are communicatively connected. The personnel equipment is worn on each ship personnel, and the positioning module, the control module and the rescue dispatching module can be respectively located at different positions of the ship, and each module and the equipment are communicatively connected through a data transmission module and a communication module to realize communication and data transmission between equipment and modules, and between modules, including but not limited to wireless communication and wired communication.

[0056] Since the personnel equipment is set on the ship personnel, when the ship personnel fall into the water accidentally, the equipment position of the personnel equipment at this time exceeds the trigger range boundary of the ship, and the positioning signal is sent to the positioning module at a certain frequency. When the positioning module receives the positioning signal sent by any personnel equipment, it can be positioned according to the time difference of arrival (TDOA) of the positioning signal to each base station in the positioning module, so as to determine the sending position of the positioning signal, that is, the equipment position of the personnel equipment, and upload it to the control module and the rescue scheduling module to provide the location data basis for subsequent rescue demand judgment and rescue implementation. After receiving the equipment position, the control module determines whether the ship personnel is in a rescue demand state according to the three-dimensional distance between the equipment position and the lowest ship side position of the ship. If so, the first rescue instruction is sent to the rescue scheduling module to trigger the rescue scheduling module to schedule the rescue equipment and execute the rescue action. If it is not in a rescue demand state, it means that the ship personnel may not be passively away from the ship at this time. At this time, it can be further determined whether the ship personnel is hanging on the ship side or whether it is a false alarm. When the control module determines that the ship's personnel are in a state of needing rescue, the rescue dispatch module can simultaneously receive the first rescue instruction and the equipment position, and determine that the ship's personnel need to be quickly rescued. It can select the currently dispatchable rescue equipment from the ship, send the equipment position and the rescue plan corresponding to the first rescue instruction to the rescue equipment, move the rescue equipment to the equipment position, and execute the rescue action through the rescue equipment to rescue the ship's personnel.

[0057] It should be noted that the rescue demand state refers to the state where the ship personnel accidentally fall into the water or passively move away from the ship. The personnel equipment is a waterproof terminal device that the ship personnel can carry with them. Its types may include but are not limited to positioning watches, positioning mobile phones, positioning bracelets, positioning accessories or other types of small devices. The positioning signal can be an ultra-wideband (UWB) signal. Ultra-wideband (UWB) technology is a wireless carrier communication technology that does not use a sinusoidal carrier, but uses nanosecond non-sinusoidal narrow pulses to transmit data, so it occupies a wide spectrum range. UWB technology has the advantages of low system complexity, low power spectrum density of transmitted signals, insensitivity to channel fading, low interception capability, and high positioning accuracy. The positioning accuracy within 100 meters is at the centimeter level, and the distance from the position of each deck to the base station is fixed. When the personnel equipment exceeds the trigger range boundary defined by the ship's side, the positioning signal can be sent at a certain frequency. When a crew member falls into the water, the entire system can identify and determine within 2-3 seconds, and issue an alarm or rescue command. Due to the high frequency of UWB signals and the speed of light propagation, the error is only a few centimeters within a distance of 100 meters.

[0058] Optionally, a positioning tag is provided in the personnel equipment and a trigger range boundary is provided on the vessel;

[0059] The personnel equipment is used to send a positioning signal to the positioning module 101 at a preset frequency when it is determined that the positioning tag exceeds the trigger range boundary.

[0060] In this embodiment, a positioning tag is provided in the personnel equipment, and a trigger range boundary is provided on the ship. The trigger range boundary can be set along the side of the ship. For ships with different ranges on each floor, the trigger range boundary can be set along different sides of the ship on each deck. Specifically, the boundary can be set by a photoelectric sensor or an infrared sensor.

[0061] When the positioning tag is not within the trigger range boundary, it indicates that there is a risk of ship personnel falling off or hanging on the side of the ship. At this time, a positioning signal can be sent to the positioning module at a preset frequency to trigger the start of the rescue system.

[0062] Among them, in order to avoid false alarms, the positioning tag can be added with the judgment condition that it is not within the trigger range boundary for a certain period of time, which can be 2-4 seconds, to avoid untimely rescue.

[0063] Furthermore, the personnel device is also provided with a help button, and the personnel device is also used for:

[0064] Receive and broadcast rescue progress information;

[0065] When the SOS button is triggered, a positioning signal is sent to the positioning module 101 at a preset frequency, and real-time communication is performed with the control module 102 .

[0066] In this embodiment, in order to improve the safety of ship personnel in the ship, the personnel equipment can also be provided with a distress button. When a person accidentally falls into the water, he can press the emergency distress button to send a distress wireless signal to the base station. When the distress button is triggered, it can also send a positioning signal to the positioning module at a preset frequency, and communicate with the control module in real time to trigger the start of the rescue system. At the same time, through real-time communication, the ship personnel can make an emergency call with the ship's duty personnel to keep in touch.

[0067] At the same time, the personnel equipment can also receive and broadcast the rescue progress information from the rescue system, so that the drowned personnel can understand the rescue situation in time, relieve tension and psychological pressure, and enhance confidence. The rescue progress information may include but is not limited to the control module successfully receiving the drowning alarm, sending an alarm to the captain, starting the flight base station, starting the rescue dispatch module, successfully locating the drowned personnel, etc. The broadcasting method can be sound signal broadcast or video broadcast.

[0068] Optionally, the positioning module 101 includes a data center, a plurality of fixed base stations and at least one flying base station, wherein the fixed base stations are arranged at different positions on the ship; the data center is specifically used for:

[0069] Respond to the positioning signal sent by any personnel equipment and detect the arrival time of the positioning signal received by each fixed base station and flying base station;

[0070] Construct multiple sets of hyperbolas based on the arrival time combined with the sending rate of the positioning signal;

[0071] The intersection points of each set of hyperbolas are determined as the equipment positions of the personnel and equipment.

[0072] See also Figure 2 , Figure 2 A comparative schematic diagram of device location positioning in an embodiment of the present invention is shown.

[0073] In this embodiment, in order to facilitate the processing of the overall signal of the ship 11, the data center can be set in the cab of the ship 11, and the fixed base station 12 can be respectively set on the ship's side on both sides of the ship 11. Specifically, three or more fixed base stations 12 can be set on both sides of the ship's side, which are set at the bow, the middle of the ship and the stern. After the personnel of the ship 11 accidentally fall into the water, if there are large winds and waves on the sea surface, the personnel of the ship 11 will rise and fall with the waves. When the personnel of the ship 11 are at the bottom of the waves, the towering waves around will affect the wireless signals of the positioning watch (i.e., the mobile device) and the fixed base station 12 on the ship, causing the signal to be discontinuous, thereby affecting the positioning. In order to reduce the impact of waves on positioning and improve the positioning accuracy of the personnel of the ship 11, the flying base station 13 can be set on the drone or rescue equipment, and the positioning signals received by the flying base station 13 and the fixed base station 12 can be combined to locate the position of the equipment, thereby reducing the impact of waves on positioning and avoiding delays in rescue trials due to positioning accuracy issues.

[0074] For example, if the rescue equipment uses a rescue drone, the rescue drone will fly to the corresponding airspace and serve as a flying base station, greatly reducing the impact of waves on positioning communications. The flying base station can combine the positioning signals received by the fixed base station to more accurately locate the equipment in three dimensions. If the rescue equipment uses an unmanned rescue boat, the flying base station is closer to the personnel and equipment, and can provide more accurate positioning data for the equipment.

[0075] In this embodiment, if the positioning center detects that the fixed base station and the flying base station receive the positioning signal, it can further obtain the arrival time of the positioning signal received by each fixed base station and the flying base station, and calculate the distance difference of each base station at the current moment according to each arrival time combined with the transmission rate of the positioning signal. After the distance difference is calculated, a hyperbola is drawn, and the intersection position of each group of hyperbolas is used as the equipment position of the personnel equipment.

[0076] For example, when the ship personnel exceed the trigger range boundary of a certain side of the ship, the data center measures that the four base stations receive the positioning signals sent by the personnel equipment at t1, t2, t3, and t4, respectively. The distances from the personnel equipment to the four base stations are r1, r2, r3, and r4, respectively. The measured distance differences of the personnel equipment relative to the four base stations are d1, d2, d3, and d4, respectively. d1=r1-r2=(t1-t2)*C, d2=r2-r3=(t2-t3)*C, d3=r3-r4=(t3-t4)*C, d4=r14-r1=(t4-t1)*C, where C is the speed of light. After obtaining the values ​​of d1, d2, d3, and d4 from the distance difference between the personnel equipment and each base station, a hyperbola plot is performed. The intersection of the four hyperbolas obtained above is the equipment location of the personnel equipment. And based on the four base stations, the positioning watch can be positioned in three dimensions to further improve the positioning accuracy. The positioning range of the base station is from the ship's side to the water surface within 500 meters from the base station, and the base station signal transmission distance is 10Km.

[0077] Since there will be time delay when UWB technology is used for positioning, especially when the ship is sailing at high speed or the water flow is fast, the position drift caused by the time delay of the person who falls into the water will be more obvious, increasing the error between the calculated position and the actual position. To this end, the positioning module in the embodiment of the present invention can perform trajectory analysis on the time-sharing measured position information based on the original positioning, and analyze factors such as ship speed, direction, water flow speed and direction, wave size, and wind direction, so as to calculate the direction of the position drift and obtain more accurate position information. Furthermore, the positioning module 101 is also used to:

[0078] When the rescue equipment is moved, obtain the current speed of the ship and the speed of the water flow;

[0079] The device position is updated according to the current ship speed and water flow speed and sent to the rescue equipment.

[0080] In this embodiment, when the rescue equipment is moved by the rescue dispatch module, the calculation of the distance equipment position has consumed a certain time t. In order to further correct the equipment position A1 (x1, y1), the current speed of the ship and the water flow speed can be obtained at this time. The equipment position is updated according to the current speed and water flow speed to obtain the latest equipment position and send it to the rescue equipment to avoid the loss of the equipment position of the ship personnel due to the influence of water flow and speed.

[0081] See also Figure 3 , Figure 3 A schematic diagram of device location update in an embodiment of the present invention is shown.

[0082] In this embodiment, the time taken for the positioning module to receive the positioning signal for the first time and calculate the device position is t seconds, and the device position is At this time, the current speed detected by the sensor on board the ship is , the water flow velocity is , then for the ship, the position of the ship personnel who fell into the water has drifted to ,at this time and The distance is At the same time, the person who fell into the water drifted along the water flow to , and The distance is At this point, the updated device coordinates for:

[0083]

[0084] In another example of the present invention, the travel path of the rescue equipment can be corrected in real time by using a path planning algorithm to correct and update the equipment position in real time, so as to improve the travel efficiency of the rescue equipment.

[0085] Optionally, the control module 102 is specifically configured to:

[0086] Calculate the hanging distance between the equipment location and the lowest side position of the ship;

[0087] If the suspension distance exceeds the distance threshold, it is determined that the ship personnel are in a state of need for rescue, and a first rescue instruction is issued to the rescue dispatch module and the flight base station to move the flight base station to the airspace where the equipment is located;

[0088] If the hanging distance does not exceed the distance threshold and the equipment position remains unchanged within the preset time period, it is determined that the ship personnel are not in a state of need for rescue and an early warning signal is output.

[0089] In an embodiment of the present invention, after receiving the device position, the control module can calculate the horizontal hanging distance between the device position and the lowest side position of the ship in order to determine the state of the ship personnel. If the hanging distance exceeds the distance threshold, it indicates that the ship personnel are passively moving away from the ship and are in danger of falling into the water. It is determined that the ship personnel are in a state of need for rescue, and the first rescue instruction is sent to the rescue scheduling module to perform the next rescue action. If the hanging distance does not exceed the distance threshold and the device position remains unchanged within a preset time period, it indicates that the ship personnel may be accidentally hanging outside the side of the ship but have not fallen into the water. At this time, it is determined that the ship personnel are not in a state of need for rescue, and an early warning signal is output to the ship's main control end for further rescue actions to prevent the ship personnel from falling.

[0090] At the same time, the first rescue command can be sent to the flying base station at the same time. The flying base station can be set up on the rescue equipment or another drone, and move to the airspace where the equipment is located through the flying base station, providing a data basis for subsequent updates and corrections of the equipment location.

[0091] The hanging distance may be set to 2 meters, and the preset time period may be set to 10 seconds to 30 seconds. The embodiment of the present invention does not limit these specific values.

[0092] In addition, the positioning accuracy of UWB within 100 meters is at the centimeter level, and the distance from the position of each deck to the base station is fixed. When the positioning watch tag is exposed to the base station signal, it can automatically track the position. When the watch is located within the range of the lowest deck, the alarm will not be triggered.

[0093] In a specific implementation, the control module may include a control circuit, a data processing module, and a control platform, which receives and processes the data information sent by the positioning module, and sends the information or instructions to the captain's ship control terminal or rescue dispatch module through the data transmission module.

[0094] Furthermore, the rescue system also includes a ship master control terminal;

[0095] The ship's master control terminal is in communication with the control module 102 and is used to call the nearest rescue equipment when receiving the warning signal to check the actual status of the ship's personnel.

[0096] In this embodiment, after the control module outputs the warning signal, a further call is made through the ship's master control terminal in the control cabin to call another rescue device that is closest to the device, so as to timely check the actual status of the ship personnel who triggered the warning signal. If the ship personnel is hanging outside the ship's side, further rescue can be carried out by the rescue personnel of the rescue equipment, effectively preventing the ship personnel from falling into the water.

[0097] Among them, the rescue equipment is at least one personnel equipment. When selecting rescue equipment for calling, at least one personnel equipment with the identity of a rescuer can be preferentially selected for calling. When there is no personnel equipment with the identity of a rescuer in a certain area where the equipment is located, in order to improve the subsequent rescue success rate and rescue efficiency, at least one personnel equipment with the identity of a non-rescuer can be selected as the rescue equipment for calling. For example, according to the basic information of the personnel, the personnel equipment corresponding to the age of 20-30 years old, with certain swimming experience and a physical fitness score greater than a certain threshold is selected.

[0098] Furthermore, the personnel equipment is provided with basic information of the personnel, and the control module 102 is also used for:

[0099] Determine the risk level of ship personnel according to their basic information;

[0100] When there are multiple ship crews in a state of requiring rescue, a second rescue instruction is generated according to each risk level and each equipment location and sent to the rescue dispatch module 103 .

[0101] In this embodiment, the personnel equipment can be distributed when the ship personnel board the ship. After the personnel equipment is authorized by the ship personnel, the basic information of the personnel corresponding to the personnel is obtained from the ship's database. According to the basic information of the personnel, such as age, pregnancy, physical fitness score, gender, whether they can swim, etc., the risk level of the ship personnel is comprehensively determined. For example, if the age is in the prime stage (20-40 years old), the corresponding weight is determined to be low. If it is less than 20 years old or more than 40 years old, the corresponding weight is increased in descending or increasing order according to age; the higher the physical fitness score, the lower the weight, and the lower the score, the higher the weight; if you can swim, the weight is 0, if you can't swim, the weight is 1, if you are male, the weight is 0, and if you are female, the weight is 1, and so on. The risk score is calculated by combining all the basic information of the personnel and the multiplication of the weights. The higher the risk score, the higher the risk level.

[0102] When there are multiple ship personnel in a state of need for rescue, they are sorted from high to low according to the risk level and the equipment location, and sorted from near to far according to the equipment location, and multiplied by the corresponding weights to calculate the final rescue level. A second rescue instruction is generated according to the rescue level and sent to the rescue scheduling module. Among them, the weight corresponding to the risk level can be higher than the weight corresponding to the equipment location, for example, it can be set to 0.6 and 0.4, and the embodiment of the present invention does not limit the specific weight.

[0103] The rescue dispatching module responds to the second rescue instruction and dispatches rescue equipment to rescue the crew members on each ship in turn according to the rescue level. For example, for the crew members on the ship with the highest rescue level, a faster drone can be dispatched for rescue, and for the crew members on the ship with the lowest rescue level, an unmanned boat can be dispatched for rescue when the drone is dispatched.

[0104] The basic information may include but is not limited to name, gender, age, identity, occupation, whether pregnant, chronic diseases, whether they can swim, physical fitness score, etc. When multiple people fall into the water, the control module will analyze the basic information of the people who fall into the water and set people who cannot swim, have chronic diseases, are pregnant, the elderly, and children as high-risk people. During rescue, under similar rescue conditions, high-risk people can be rescued first.

[0105] Optionally, the rescue equipment is provided with an infrared imaging component, an automatic delivery component and an automatic recovery component; the rescue equipment includes a drone and an unmanned boat;

[0106] An infrared imaging component, used to obtain real-time images through infrared radiation when the light intensity of the external environment is less than a preset light threshold;

[0107] An automatic delivery component is used to deliver the life-support components on the rescue equipment when the rescue equipment moves to the equipment location for use by the ship's personnel;

[0108] Automatic recovery kit, used to recover and secure life support kit when rescue equipment is moved to the ship.

[0109] In this embodiment, the rescue equipment may be provided with an infrared imaging component, an automatic delivery component, and an automatic recovery component. When the rescue equipment is moved, if the light intensity of the current external environment is less than the preset light threshold, the infrared imaging component may be used to obtain real-time images by infrared radiation to improve the convenience of the rescue equipment at night. When the rescue equipment moves to the equipment location, the specific location of the person who falls into the water may be observed by the infrared imaging component on the rescue equipment, and the life-support component may be delivered to the specific location of the person who falls into the water by the automatic delivery component for use by the ship's personnel who fall into the water. When the rescue equipment returns to the ship and stops at the corresponding position, the life-support component is recovered and fixed by the automatic recovery component. Alternatively, the life-support component may be recovered manually.

[0110] Among them, the life-support component can be oxygen masks, ropes, life jackets, life buoys and other equipment.

[0111] In the specific implementation, drones and unmanned boats are equipped with video transmission and voice communication devices, which can search, observe and contact people who fall into the water. Drones and unmanned boats are equipped with infrared imaging devices, which are convenient for searching people who fall into the water at night or in bad weather.

[0112] In addition, when the rescue equipment moves in the area where the equipment is located, it can hover at the equipment location where the person who fell into the water is located. It can carry a flying base station to send positioning information. The rescue equipment can also activate sound and light alarms to indicate the patient's location, greatly improving the rescue success rate at night or in weather conditions with poor visibility. At the same time, when the rescue situation is more complicated and human rescue is required, the drones and unmanned boats in the rescue equipment can assist rescuers in quickly locating and carrying out rescue. At the same time, the rescue equipment can also provide power to help the person who fell into the water move to the hull.

[0114] In an embodiment of the present invention, when a person or equipment exceeds the boundary of the trigger range, the positioning module is used to generate the equipment position and send it to the control module. The control module determines whether a person has fallen into the water (i.e., a rescue requirement state) according to the equipment position. If so, a rescue instruction and positioning information are sent to the rescue dispatch module, and the flight base station is started at the same time to move the flight base station to the airspace where the equipment is located, and provide data for subsequent updates and corrections to the equipment position; at the same time, the rescue module dispatches the rescue equipment, and the drone or unmanned boat moves to the equipment position to perform the rescue action; if it is determined that no person has fallen into the water, an early warning signal can be sent to the ship's main control terminal to inform the captain to perform further rescue.

[0115] In an embodiment of the present invention, a safety rescue system for ship personnel is provided, including a positioning module, a control module, a rescue dispatching module and a plurality of personnel equipment connected in communication; the positioning module is used to respond to the positioning signal sent by any personnel equipment, locate the equipment position of the personnel equipment and upload it to the control module and the rescue dispatching module respectively; the control module is used to judge whether the ship personnel are in a state of rescue demand according to the comparison result of the equipment position and the lowest ship side position; if so, the first rescue instruction is sent to the rescue dispatching module; the rescue dispatching module is used to dispatch the rescue equipment from the ship and move to the equipment position to perform the rescue action when the first rescue instruction and the equipment position are received. Therefore, through the communication between the modules, when the ship personnel need rescue, they can quickly locate and quickly dispatch the rescue equipment to perform the rescue action, so as to timely track and locate the ship personnel who are in danger of falling into the water, effectively avoid the best rescue time, and improve the rescue efficiency of the ship personnel.

[0117] An embodiment of the present invention provides a method for safely rescuing ship personnel, which is applied to a ship personnel rescue system in any embodiment of the present invention, and the method includes:

[0118] Step 501, when a positioning signal sent by any personnel device is received, the device position of the personnel device is located;

[0119] Step 502, judging whether the personnel of the ship to which the personnel equipment belongs are in a state of requiring rescue according to the equipment position and the lowest ship side position;

[0120] Step 503, if yes, send a first rescue instruction to dispatch rescue equipment from the ship and move it to the equipment location to perform rescue actions;

[0121] Step 504: If not, output a warning signal.

[0122] In an embodiment of the present invention, when the positioning module in the ship personnel rescue system receives a positioning signal sent by any personnel equipment, the TDOA and UWB technologies can be used to locate the equipment position of the personnel equipment according to the positioning signal, and further sent to the control module. The control module calculates the horizontal hanging distance between the equipment position and the lowest ship side position, and determines whether the ship personnel to which the personnel equipment belongs is passively moving away from the ship according to the hanging distance. If so, it is determined that the ship personnel to which the personnel equipment belongs is in a state of rescue demand. At this time, a rescue instruction can be sent to send a first rescue instruction to the rescue dispatching module to dispatch the rescue equipment from the ship and move it to the equipment position to perform the rescue action. Otherwise, it indicates that the ship personnel may be hanging outside the ship side. At this time, an early warning signal is output to the ship's main control terminal, so that the captain or other rescue personnel can call the rescue equipment near the equipment position for further rescue.

[0123] In addition, if there are multiple crew members on board who need rescue at the same time, the rescue equipment can be driven to perform rescue operations in sequence based on the risk level determined by the basic information of the crew members and the location of the equipment.

[0124] In the embodiment of the present invention, when a positioning signal sent by any personnel equipment is received, the equipment position of the personnel equipment is located; according to the equipment position and the lowest ship side position, it is determined whether the personnel of the ship to which the personnel equipment belongs are in a state of rescue demand; if so, a first rescue instruction is sent to dispatch the rescue equipment from the ship and move it to the equipment position to perform the rescue action; if not, an early warning signal is output. In this way, the personnel of the ship who are in danger of falling into the water can be tracked and located in time, effectively avoiding the best rescue time and improving the rescue efficiency of the personnel of the ship.
