Description

Offshore lifesaving equipment and method

Technical Field

Background

The existing offshore lifesaving equipment triggers the lifesaving equipment to alarm and position on the basis of a water contact electrode switch after falling into water, but the existing water contact electrode switch does not distinguish seawater from fresh water, namely does not distinguish media contacted by the water contact electrode switch, so that the existing equipment is easily mistakenly triggered due to the influence of weather environments such as rain, fog, dew and the like. In addition, in the existing mode, only the trigger of the water-touching electrode switch is used, so that when the marine life-saving equipment is used for alarming and positioning, the possibility that the water-touching electrode switch is mistakenly contacted with the seawater due to sea wave splashing or other objective reasons exists, and the problem of mistaken trigger of the marine life-saving equipment is caused. In addition, when the marine life-saving equipment is triggered to work based on the pressure sensor, the conventional life-saving equipment triggered only based on the passive pressure switch is easy to trigger the pressure switch mistakenly or not due to low sensitivity and poor reliability. The existing active pressure sensor has high precision, but the pressure sensor and a CPU (central processing unit) need to be continuously supplied with power for pressure detection and threshold judgment, so that the standby power consumption of the marine life-saving equipment is increased.

Detailed Description

The embodiment of the specification provides a marine life-saving device and an implementation method thereof.

With the development of fishery, marine transportation industry and marine transportation industry, marine operators are increasing year by year, and marine operators are often influenced by marine climate and the like when working on the basis of marine operation ships and the like or performing other marine transportation work, so that accidents such as reef touch, collision, sinking and the like occur on the marine operation ships, the marine transportation equipment and the like, and therefore, the marine life-saving equipment is important safety protection equipment for the marine operators.

At present, lifesaving equipment adopted by people falling into water mainly comprises a life jacket, a life ring, a life rope, an inflatable rubber raft, a lifesaving stretcher and the like. However, after the conventional lifesaving equipment falls into water, due to the lack of a positioning and position reporting device, the rescue plane or ship is difficult to find the position of the person in danger, and a gold rescue period of 72 hours is often missed, so that the search and rescue efficiency and the search and rescue success rate are very low. Generally, after people fall into water, the maritime life-saving equipment with the positioning device triggers the life-saving equipment to alarm and position by the water-touching electrode switch or triggers the life-saving equipment to alarm and position by the pressure switch. However, when the lifesaving equipment is triggered to alarm and position only based on the water-contacting electrode switch, because the existing water-contacting electrode switch does not distinguish the medium contacted with the water-contacting electrode switch, the existing lifesaving equipment triggered based on the water-contacting electrode switch is often mistakenly triggered due to the influence of weather environments such as rain, fog and dew, and therefore, the reliability is poor. The pressure switch comprises a passive pressure switch and an active pressure switch, wherein the conventional passive pressure switch has the problems of large volume, low sensitivity, poor reliability and the like, and the conduction threshold value is within a range interval and cannot be accurate to a fixed value, so that the pressure switch is easily triggered by mistake or is not triggered. The active pressure sensor has high precision, but needs to continuously supply power to the pressure sensor and the CPU for pressure detection and threshold judgment, so that the standby power consumption of the marine life-saving equipment is increased.

In order to solve the technical problems, embodiments of the present specification provide a marine life saving device and an implementation method thereof, which implement determination of a position of the marine life saving device through a positioning module in the marine life saving device, thereby alleviating a problem that conventional life saving devices cannot acquire position information of a person falling into water, which causes difficulty in rescuing the person falling into water. The water-contact electrode switch with the electrode conductance detection function is adopted, and the triggering mode is determined only when the water-contact electrode switch is continuously contacted with seawater, so that the problem that equipment is misinformed due to the influence of weather environments such as rain, fog and dew because the traditional water-contact electrode switch does not distinguish the contacted medium is solved. Whether the passive pressure sensor is triggered or not is determined on the basis of the shrinkage, so that the problems that the conduction threshold value is within a range interval and cannot be accurate to a fixed value when the passive pressure sensor or the active pressure switch is used and the active pressure switch needs to face continuous power supply are solved. Meanwhile, the problem of low triggering reliability when the trigger is only based on the pressure switch or only based on the water-touching electrode switch is solved based on the linkage mode of the water-touching electrode switch and the passive pressure switch, and the false alarm rate of the marine life-saving equipment is reduced.

In order to make those skilled in the art better understand the technical solutions in the present specification, the technical solutions in the embodiments of the present specification will be clearly and completely described below with reference to the drawings in the embodiments of the present specification, and it is obvious that the described embodiments are only a part of the embodiments of the present specification, and not all of the embodiments. All other embodiments obtained by a person of ordinary skill in the art based on the embodiments of the present specification without any creative effort shall fall within the protection scope of the present specification.

As shown in FIG. 1, the embodiment of the specification provides a structural schematic diagram of a marine life-saving device. As shown in fig. 1, the marine life-saving device comprises a control processing module, a positioning module for providing positioning information for the control processing module, and a communication module for transmitting the positioning information to a remote rescue terminal device and receiving information related to the remote rescue terminal device. The device also comprises a power supply module for awakening the control processing module and providing electric energy for the positioning module and the communication module, a water-touching electrode switch and a passive pressure switch which are used for controlling the power supply module to be started through linkage triggering, the control processing module is awakened to carry out positioning alarm based on a linkage triggering mode, and the water falling alarm can be automatically triggered only under the condition that certain conductance value and pressure are simultaneously met by adopting a mode of linkage combination of the water-touching electrode switch with a plurality of electrode conductance detections and the passive pressure switch. The problem of high power consumption caused by the fact that the marine life-saving equipment is in a working state all the time is avoided, and meanwhile, the problem of unreliability caused by triggering of a single sensor is avoided through linkage triggering of the water trigger electrode switch and the passive pressure switch.

The passive pressure switch is composed of an isolation diaphragm and a pre-tightening elastic element. The touch electrode switch is composed of a preset number of electrodes and a conductance detection passive circuit, wherein the preset number of electrodes are arranged at the bottom of the marine life-saving equipment at equal intervals and are covered and protected through nonmetal. For example: taking the application of the touch electrode switch to the marine life-saving equipment as an example, in a certain application scenario of the present specification, the touch electrode switch totally comprises four detection electrodes made of seawater erosion resistant gold-plated materials, which are respectively: the electrode A, the electrode B, the electrode C and the electrode D are uniformly distributed at the bottom of the marine life-saving equipment, the periphery of the marine life-saving equipment is covered with nonmetal protection, and the distance between the 4 electrodes is 2cm. Based on the setting mode, the traditional water contact electrode switch is upgraded from double-electrode detection into multi-electrode detection, and the problem that the water contact electrode switch is easily mistakenly triggered due to objective factors such as splashing seawater and the like is solved. In addition, it should be further described with reference to fig. 1 that the control processing module in the marine life-saving equipment can be used for equipment control and data communication, and realizes initialization, parameter setting, positioning and communication data processing, information interaction, flashing of a stroboscopic module, camera shooting and other functions of a positioning module, a communication module and the like.

The existing water contact electrode switch does not distinguish a medium contacted with the water contact electrode switch, so that the problem that the water contact electrode switch is mistakenly triggered in rainy and foggy weather is easily caused, and the problem that the water contact electrode switch is unreliable is further caused. In order to solve the problem, in one or more embodiments of the present specification, the water contact electrode switch is configured to obtain a conductivity value of a current located medium, obtain a mutual distance between electrodes in the water contact electrode switch and a cross-sectional area of each electrode, and then determine a current conductivity value between each electrode of the water contact electrode switch according to the conductivity value of the current located medium obtained by the water contact electrode switch, the mutual distance between each electrode and the cross-sectional area of each electrode. And if the current conductivity value of each electrode is larger than the preset conductivity value threshold value, triggering the touch electrode switch to close the touch electrode switch. When the marine life-saving equipment is used, the problem that the conductance values of the water-contacting electrode switch in the marine life-saving equipment under seawater and fresh water are greatly different is considered, so that the water-contacting electrode switch can obtain the current conductance values of all electrodes based on the current conductivity value of a medium in combination with the mutual distance between all electrodes in the water-contacting electrode switch and the sectional areas of all electrodes, and further, whether the water-contacting electrode is triggered or not is judged, and the problem of false triggering caused by weather is effectively avoided.

Further, in one or more embodiments of the present disclosure, the passive pressure switch consists essentially of an isolation diaphragm and a preloaded elastic element. After the marine life-saving equipment falls into water, water pressure is transmitted to the pre-tightening elastic element through the isolation diaphragm in the passive pressure switch, and when the water pressure exceeds a preset conduction pressure threshold value, the switch is triggered. In the process, the passive pressure switch is used for acquiring the shrinkage of the pre-tightening elastic element and the elastic coefficient of the pre-tightening elastic element. And if the contraction quantity of the pre-tightening elastic element is determined to be larger than a preset contraction quantity threshold value and the elastic coefficient of the pre-tightening elastic element is smaller than a preset elastic coefficient threshold value, determining that the current water pressure of the passive pressure switch is larger than a preset conduction pressure threshold value, and triggering the passive pressure switch to be closed.

Further, in one or more embodiments of the present description, as shown in fig. 1, the communication module includes: the Beidou navigation system comprises a wireless communication module, a Beidou RD communication module, a wireless communication module antenna and a Beidou positioning communication antenna; the positioning module includes: big dipper RN orientation module. The wireless communication module is electrically connected with the control processing module and used for establishing short-distance communication between the marine life-saving equipment and the remote rescue terminal equipment, so that the wireless communication module antenna in the marine life-saving equipment can transmit the positioning information of the marine life-saving equipment and the image information acquired by the acquisition equipment to the remote rescue terminal equipment through the short-distance communication. Big dipper location communication antenna for big dipper RD communication module's signalling and predetermine big dipper communication system in the receipt of big dipper satellite signal, for example: to the receipt of big dipper satellite positioning signal, the receipt of big dipper satellite signal of out and the transmission of big dipper satellite signal of inbound, what need explain in addition that this big dipper positioning communication antenna is trinity multifrequency combination antenna.

Big dipper RD communication module and control processing module electric connection for control processing module awakens up the back and communicates through big dipper location communication antenna and default big dipper communication system, and acquires marine life-saving equipment's locating information according to two star active positioning. This big dipper RD communication module communicates through big dipper location communication antenna and predetermines big dipper communication system and specifically the process does: the Beidou RD communication module is used for completing format formation, information coding spread spectrum, up-conversion and power amplification of the Beidou satellite inbound signals and finally sending the signals through a Beidou positioning communication antenna; meanwhile, the method is used for amplifying, down-converting, pseudo code capturing, tracking, de-spreading, carrier wave recovering, demodulating and decoding the Beidou satellite outbound signals received by the Beidou positioning communication antenna to obtain the outbound signal information. And the Beidou RN positioning module is connected with the Beidou positioning communication antenna and used for receiving satellite signals in a preset Beidou communication system based on the Beidou positioning communication antenna after the Beidou RN positioning module is started successfully, and acquiring positioning information of the marine life-saving equipment after the satellite signals are amplified, down-converted, captured, tracked, de-spread, decoded and positioned and resolved.

Further, in one or more embodiments of the present specification, as shown in fig. 1, the marine life saving equipment further includes: the infrared camera is electrically connected with the control processing module, and the stroboscopic module is electrically connected with the control processing module. Wherein infrared camera is used for according to control processing module's collection instruction gathers image information, can be through the frequency through presetting, regularly shoot the face characteristic of the personnel of falling into water and the peripheral environment of the personnel of falling into water, then send for remote rescue terminal equipment through the wireless communication module among the marine life-saving equipment, perhaps send for emergency rescue management center through RD communication module, make remote rescue terminal equipment or emergency rescue management center can obtain the vital sign judgement and the peripheral environment of the personnel of falling into water, thereby be convenient for analyze out suitable rescue mode and in time salvage the personnel of falling into water. And the stroboscopic module adopts a special LED driving chip and is matched with the low-power high-brightness LED lamp bead to alarm and flash according to the alarm instruction of the control processing module. After the stroboscopic module is triggered to operate by the marine life-saving equipment, under the control of the control processing module, the illumination intensity of the environment where the current person falling into the water is located is detected through the built-in photosensitive sensor of the stroboscopic module, if the current illumination intensity is smaller than a preset illumination intensity threshold value, the stroboscopic module is started, namely the stroboscopic module is started only when the illumination intensity is smaller than the set threshold value, the stroboscopic module is subjected to flashing alarm display according to the set frequency, and the rest time periods are closed. Among them, it should be noted that: the resistance value of the photosensitive sensor is in inverse proportion to the illumination intensity, and the weaker the illumination intensity is, the larger the resistance value is. When the water falling positioning alarm working state is manually or automatically entered, the photosensitive sensor detects the external illumination intensity and shows different resistance values according to different illumination intensities, when the resistance value of the photosensitive sensor is larger than a set threshold value, the illumination intensity is smaller than the set illumination threshold value, and the stroboscopic module is started. By means of the mode of flashing and alarming after the illumination intensity threshold value is judged, the effect that the position of people falling into water can be quickly determined by a peripheral rescue ship under the condition of low illumination is achieved. Meanwhile, the stroboscopic module determines the accumulated working time according to the flashing starting time and the current time, and if the accumulated working time is determined to be larger than a preset time threshold, the flashing frequency of the stroboscopic module is reduced in order to save the electric quantity of the marine life-saving equipment. For example: when the preset time period is 8 hours, if the accumulated working time reaches 8 hours according to the flashing start time and the current time, in order to save the electric quantity of the terminal, the flashing frequency of the stroboscopic module can be reduced from 1 second/time to 5 seconds/time. The stroboscopic module in the embodiment of the description can greatly reduce the average working power consumption of the marine life-saving equipment and prolong the endurance time of the marine life-saving equipment by combining two methods of controlling stroboscopic opening based on the illumination intensity and reducing the flashing frequency based on the accumulated working time.

As shown in fig. 2, the present specification provides a method for implementing a life saving device on sea, including the following steps;

s201: the touch electrode switch obtains the current conductance value between each electrode, so that the touch electrode switch determines whether to trigger the switch-on or not based on the current conductance value.

Firstly, the problem of false triggering caused by transient seawater contact of the water-touching electrode switch, such as false triggering of the water-touching electrode switch caused by splashed water during offshore operation, is avoided. In the embodiment of the specification, the current conductivity values among the electrodes are obtained by the touch electrode switch, so that the touch electrode switch is determined to be triggered after the current conductivity values among the electrodes are jointly judged, the marine life-saving equipment is guaranteed to give an alarm only when the marine life-saving equipment is continuously contacted with seawater, and the reliability of the touch electrode switch is improved.

Further, the current touch electrode switch cannot distinguish the medium, and is easily affected by rainwater weather under certain conditions, so that the false alarm rate is high. In one or more embodiments of the present specification, the step of acquiring a current conductance value between the electrodes by the touch electrode switch, so that the touch electrode switch determines whether to trigger the closing based on the current conductance value specifically includes the following steps:

firstly, the conductivity value C of the seawater is 5-50 ms/cmMeanwhile, the conductivity value C = 0.05-1 ms/cm of the fresh water, and the conductivity values are obviously different, so that the conductivity values of the seawater and the fresh water also have huge difference values. In the embodiment of the description, the touch electrode switch firstly obtains the conductivity value C of the medium at present, and obtains the mutual distance L between each electrode and the sectional area S of each electrode in the touch electrode switch. And then determining the current conductivity value G of the touch electrode switch according to the conductivity value C of the medium at present, the mutual distance L between the electrodes and the sectional area S of the electrodes. That is to say according to the formula

The current conductance value of the trigger electrode switch is determined. For example: taking the conductivity value C of the seawater between 5 and 50ms/cm, the conductivity value C =0.05 to 1ms/cm of the fresh water, the mutual distance L =2cm between the electrodes and the sectional area A =0.1cm2 of the electrodes as examples, the conductivity value ^ is the sea water if the medium is the sea water>

I.e. a resistance of R =1/G =400 Ω -4 k Ω. If the medium is fresh water, the conductance value is greater or less>

I.e. resistance values of R =1/G =20k Ω -400 k Ω. According to the process, if the current conductance value of the touch electrode switch is determined to be larger than the preset conductance value threshold value, the touch electrode switch is triggered, so that the touch electrode switch is closed.

Specifically, in one or more embodiments of the present disclosure, if it is determined that the current conductance value is greater than the preset conductance value threshold, the triggering of the trigger electrode switch is triggered, which specifically includes the following steps: and acquiring current conductance values among the electrodes one by the touch electrode switch based on the steps, and if the current conductance values among the electrodes are determined to be larger than a preset conductance threshold value, indicating that the touch electrode switch is triggered. The current conductance values between the electrodes are all triggered to give an alarm, so that the marine life-saving equipment can be triggered only when being in continuous contact with seawater, and the reliability of triggering the water-contact electrode switch is improved. In addition, the setting of the conductivity threshold value is related to the medium where the marine life-saving equipment is located, the conductivity threshold value of the water electrode switch can be set to be 0.1ms as the conductivity value of the seawater is 0.25-2.5 ms and the conductivity value of the fresh water is 0.0025-0.05 ms, and the water electrode switch is triggered when the conductivity value is more than 0.1ms, namely the resistance value is less than 10k omega. As the conductance value of the seawater is far larger than the set threshold value of 0.1ms, and the conductance value of the fresh water is far smaller than the set threshold value of 0.1ms, the problem that the offshore life-saving equipment is triggered in rainy and foggy weather can be avoided.

S202: the passive pressure switch acquires the contraction amount of the pre-tightening elastic element to determine whether to trigger the closing of the passive pressure switch or not based on the contraction amount of the pre-tightening elastic element.

The passive pressure switch mainly comprises an isolation diaphragm and a pre-tightening elastic element. After the marine life-saving equipment falls into water, water pressure is transmitted to the pre-tightening elastic element through the isolation diaphragm in the passive pressure switch, and the switch is triggered after the water pressure exceeds a preset conduction pressure threshold value. In the embodiment of the specification, the passive pressure switch firstly acquires the shrinkage of the pre-tightening elastic element in the process, so that whether the current water pressure can trigger the closing of the passive pressure switch or not is conveniently determined according to the shrinkage.

Further, in order to ensure that the passive pressure switch can trigger the closing after the pre-tensioned elastic element reaches a certain amount of contraction, in one or more embodiments of the present specification, the passive pressure switch acquires the amount of contraction of the pre-tensioned elastic element to determine whether to trigger the closing of the passive pressure switch based on the amount of contraction of the pre-tensioned elastic element, the method further comprises the steps of:

firstly, the passive pressure switch needs to obtain a preset alarm depth D, the density rho of a medium where the passive pressure switch is located and the surface area S of an isolation diaphragm in the passive pressure switch, so that a preset conduction pressure threshold value F of the passive pressure switch is determined according to the preset alarm depth, the density and the surface area. For example: setting the surface area of the isolation diaphragm to be S =1cm2, the density of the seawater medium to be ρ =1g/cm3, the gravity coefficient g =9.8N/kg, and the alarm depth D =20cm, wherein when the water depth D =20cm, the water pressure borne by the isolation diaphragm is the preset conduction pressure threshold, and the following formula is a calculation formula of the preset conduction pressure threshold:

F1＝ρDSg＝1g/cm3×20cm×1cm2×9.8N/kg＝0.196N。

according to the above, after the marine life-saving equipment falls into water, water pressure is transmitted to the pre-tightening elastic element through the isolation diaphragm in the passive pressure switch, the elasticity F2= kxDeltaX of the pre-tightening elastic element, k is an elastic coefficient, and DeltaX is a contraction quantity of the pre-tightening elastic element. And acquiring a shrinkage threshold of the pre-tightening elastic element under the preset conduction pressure threshold according to the first relative distance and the second relative distance. And then the passive pressure switch determines an elastic coefficient threshold value of the pre-tightening elastic element in the passive pressure switch according to the shrinkage threshold value and the relation between the elastic force of the pre-tightening elastic element and the pressure of the isolation diaphragm, so as to set the pre-tightening elastic element in the passive pressure switch based on the elastic coefficient threshold value. Following the above example: and setting the relative distance d =0.1cm between the metal wafer and the electrode, and when the shrinkage threshold value delta X =0.1cm of the pre-tightening elastic element, the elastic force F2 of the pre-tightening elastic element is less than the pressure F1 of the isolation diaphragm, so that the pressure switch can be triggered when the water depth is 20 cm. The elastic coefficient can be calculated

I.e. the elastic modulus threshold is 196N/m.

Specifically, in one or more embodiments of the present description, the passive pressure switch acquires the shrinkage of the pre-tensioned elastic element to determine whether to trigger the closing of the passive pressure switch based on the shrinkage of the pre-tensioned elastic element, and specifically includes the following processes:

firstly, the passive pressure switch acquires the shrinkage of the pre-tightening elastic element and the elastic coefficient of the pre-tightening elastic element. If the fact that the shrinkage of the current pre-tightening elastic element is larger than the preset shrinkage threshold value and the elasticity coefficient of the pre-tightening elastic element is smaller than the preset elasticity coefficient threshold value is determined, the fact that the current water pressure of the passive pressure switch is larger than the preset conducting pressure threshold value is determined, at the moment, the passive pressure switch can be triggered, and the passive pressure switch is enabled to be closed.

S203: and if the water trigger electrode switch and the passive pressure switch are triggered to be closed, the power module of the marine life-saving equipment is started to wake up and start the control processing module and supply power to each module in the marine life-saving equipment.

Based on the above step S201 and the above step S202, if both the water trigger electrode switch and the passive pressure switch are triggered, so that both the water trigger electrode switch and the passive pressure switch are in a closed state, the power module of the marine life-saving device is turned on, so that the control processing module is awakened by the power module and power is supplied to each module in the marine life-saving device, so that the marine life-saving device is in a working state. In the embodiment of the specification, after the marine life-saving equipment falls into water, the water touching electrode switch and the passive pressure switch adopting multi-electrode conductance detection are automatically triggered. Through the mode that the linkage triggers for marine life-saving equipment only satisfies under certain conductance value and the condition of pressure simultaneously, touch water electrode switch and passive pressure switch and trigger simultaneously, power module gives big dipper RN orientation module, big dipper RD communication module, wireless communication module, control and processing module, the stroboscopic module, the power supply circuit of CMOS infrared camera just can open, and marine life-saving equipment just can begin the automatic triggering warning that falls into water, the shortcoming of the false triggering that current touch water electrode switch easily receives weather environment influences such as rain fog, dew, wave splatter and lead to has been solved, and current pressure switch sensitivity is low, the reliability is poor, the easy shortcoming of false triggering or not triggering. In addition, it should be noted that the marine life-saving equipment in the embodiments of the present specification may also be manually turned on, and the power module skips threshold detection of the water contact electrode switch and the passive pressure switch, forcibly powers on each module, and enters a working state of manually triggering an alarm when falling into water. And the device can be shut down manually, so that the device can be forcibly relieved from alarming and shut down, and the adaptability of the marine life-saving device is improved.

S204: the control processing module acquires the positioning information of the marine life-saving equipment based on a Beidou RD communication module or a Beidou RN positioning module in the marine life-saving equipment, controls a preset infrared camera to collect image information and controls a preset stroboscopic module to flicker.

After the power is supplied to each module in the marine life-saving equipment based on the process, the control processing module acquires the positioning information of the marine life-saving equipment according to the Beidou RD communication module or the Beidou RN positioning module in the marine life-saving equipment so as to quickly lock the position of the person falling into the water corresponding to the marine life-saving equipment. And the infrared camera is controlled to collect image information, so that the physical sign information and the surrounding environment information of the person falling into the water can be analyzed based on the image information subsequently, and a corresponding rescue scheme can be determined according to the physical sign information and the surrounding environment information. Meanwhile, in order to conveniently lock the personnel falling into the water corresponding to the marine life-saving equipment under the condition of low illumination for the surrounding ships or other rescue equipment, the stroboscopic module adopts a special LED driving chip and is matched with a low-power high-brightness LED lamp bead for alarming and flashing according to the alarming instruction of the control processing module. In addition, by combining the description of the stroboscopic module in the marine life-saving equipment, the stroboscopic module in the embodiment of the description can greatly reduce the average working power consumption of the marine life-saving equipment and prolong the endurance time of the marine life-saving equipment by combining two methods of controlling stroboscopic starting based on the illumination intensity and reducing the flashing frequency based on the accumulated working time.

Specifically, in one or more embodiments of the present specification, the control processing module obtains the positioning information of the marine life-saving device based on a beidou RD communication module or a beidou RN positioning module in the marine life-saving device, and specifically includes the following processes:

firstly, the control processing module acquires a corresponding instruction output by the Beidou RN positioning module, so that the corresponding instruction is analyzed according to a preset transmission protocol to determine whether the Beidou RN positioning module is successfully started. If the Beidou RN positioning module is determined to be started successfully, the Beidou RN positioning module acquires satellite signals in a preset Beidou communication system received by a Beidou positioning communication antenna connected with the Beidou RN positioning module, and accordingly positioning information of the marine life-saving equipment is obtained by resolving positioning of the Beidou RN positioning module on the satellite signals. If unsuccessful, then in order to avoid the problem that the rescue time that RN location start time process caused is lengthened, practice thrift the rescue time of the personnel of falling into water, control processing module just according to big dipper RD communication module, acquires the positioning information of predetermineeing big dipper communication system transmission that the big dipper location communication antenna that is connected with big dipper RD communication module received. After the Beidou RD communication module sends active positioning to the Beidou communication system through the Beidou positioning communication antenna, the ground central station in the Beidou communication system calculates the position of the marine life-saving equipment according to the positioning request of the Beidou RD communication module forwarded by the Beidou satellite and the elevation data of the ground. And then the position is sent to a Beidou RD communication module through a Beidou satellite, so that the position of the marine life-saving equipment is quickly obtained. In the process, the initial catching time of the RD communication module is calculated, the time delay of sending the positioning request information to the ground central station is delayed, the time length of calculating the position information by the ground central station is long, the time delay of sending the position information to the RD communication module by the ground central station is not more than 3S, the whole RD active positioning time is not more than 3S, compared with the RN cold start initial positioning time of 40-60S, the cold start positioning time is effectively reduced, the real-time performance of the whole system is improved, therefore, the timeliness of obtaining the position of the marine life-saving equipment is effectively improved through the combination of two positioning modes, and the life-saving rate of people falling into water is increased.

S205: the control processing module sends the positioning information and the image information to corresponding remote rescue terminal equipment or an emergency rescue management center based on a communication module so as to realize rescue of people falling into water corresponding to the marine life-saving equipment.

After the position of the marine life-saving equipment and the image information acquired by the infrared camera are obtained in the above manner, the control module in the embodiment of the description sends the positioning information and the image information to the corresponding remote equipment based on the communication module, so that people falling into water using the marine life-saving equipment can be rescued.

Further, in one or more embodiments of the present specification, in extreme weather, a person falling into the water using the marine life-saving device may cause a rescue risk to rise, so that a ship partially installed with a remote rescue terminal device cannot rescue the person falling into the water, and therefore, in order to achieve effective rescue for the person falling into the water on the premise of ensuring the safety of the ship. In the embodiment of the specification, the marine life-saving equipment firstly acquires image information acquired by acquisition equipment, inputs the image information into a deep learning network model, identifies risk types contained in the image information based on the deep learning network model, and then acquires a plurality of risk influence factors corresponding to the risk types in the image information according to a preset risk condition table, so as to predict risk levels corresponding to the risk types based on the risk influence factors. After the risk level corresponding to the image information is obtained, the marine life-saving equipment determines the effective coverage area of the wireless communication module, so that the positioning information, the image information and the risk level corresponding to the image information, which are obtained by the marine life-saving equipment in the process, are sent to the ship with the remote rescue terminal equipment in the effective coverage area through the built-in wireless communication module. And determining whether to rescue the ship provided with the remote rescue terminal equipment in the effective coverage range according to the risk level corresponding to the image information. And if the remote rescue terminal device is determined to be capable of rescuing, the remote rescue terminal device sends rescue confirmation information to the marine life-saving device, and meanwhile, the ship provided with the remote rescue terminal device carries out rescue. And if the rescue cannot be carried out, the remote rescue terminal equipment sends feedback information of incapability of rescue to the marine life-saving equipment.

In order to increase image features of image information acquired by marine life-saving equipment and improve accuracy of model recognition images, the method further includes the following steps before inputting the image information into the deep learning network: firstly, dividing an initial image acquired by an acquisition device into a plurality of sub-regions according to a preset segmentation area, thereby obtaining the plurality of sub-regions of the initial image. In order to highlight special information contained in the image and avoid the problem that detail influence factors cannot be determined due to the fact that the colors of the sea and the sky are too close to each other, after the multiple sub-regions of the initial image are obtained, binarization processing is carried out on the sub-regions according to a preset binarization threshold value, and therefore the binarization image of the initial image is obtained. Then, in order to remove noise data in the image, weighting processing is carried out on each image pixel point in the binary image of the initial image through preset filtering cores, so that noise filtering of the binary image of the initial image is realized, and a processed image is obtained. The image processing method is convenient for marine life-saving equipment to input and transmit the processed image to a preset deep learning network model for identification, and the risk types contained in the image information are output, so that a plurality of risk influence factors corresponding to each risk type are obtained according to a preset risk condition table.

Further, in the embodiment of the present specification, predicting the risk level corresponding to the current risk type based on the multiple risk influencing factors specifically includes the following steps: and inputting the plurality of risk factors into a preset vector machine model so as to obtain the risk level of the current risk type predicted by the vector machine model. In the embodiments of the present disclosure, in order to improve the reliability and accuracy of prediction of a vector machine model, first, each parameter in an improved algorithm corresponding to the vector machine model is obtained, and each parameter is initialized. It should also be noted that the parameters in the improved algorithm include: forward population size, maximum iteration times, inertia weight and the like of the particles are searched forward. Then, initializing a forward population formed by the forward search particles according to a preset reverse learning mechanism to obtain the coordinate position of each reverse search particle in a reverse population corresponding to the forward population. After the coordinate positions of the reverse search particles are obtained, in order to obtain the optimal search particles, the embodiment of the present specification obtains a preset fitness function, so that the fitness values of the search particles in the forward population and the reverse population are calculated according to the preset fitness function, and the search particle with the smallest fitness value is determined as the optimal search particle of the initial search population. It is understood that a smaller fitness value indicates a better predicted result. And then randomly generating a random number within a preset range to determine the coordinate position of the search particle in the current search population based on the value of the random number, obtaining the position information corresponding to the search particle with the minimum fitness value through iterative computation, and determining the optimal parameter of a preset least square support vector machine model which meets the requirement based on the position information. And adjusting and improving the vector machine model according to the optimal model parameters to obtain the optimized vector machine model, so that the prediction accuracy of the risk grade of the risk type is improved.

Therefore, the current risk level is determined by the marine life-saving equipment according to the acquired image information, and it can be understood that if the current risk level is greater than the risk which can be borne by the ship provided with the remote rescue terminal equipment, the ship provided with the remote rescue terminal equipment cannot rescue people falling into the water. Therefore, in one or more embodiments of the present specification, the determining, by the ship with the remote rescue terminal device installed in the effective coverage area, whether to rescue according to the risk level corresponding to the image information specifically includes the following steps.

First, basic information of each ship installed with a remote rescue terminal device is acquired. It should be noted that the basic information includes: the type of the vessel, the total payload, the number of crew, the number and type of rescue equipment. And comparing the basic information of each ship provided with the remote rescue terminal equipment to sequence the rescue capacity of each ship. For example: based on the types of the ship 1 on which the remote rescue terminal device is installed and the ship 2 on which the remote rescue terminal device is installed, if it is determined that the ship 1 on which the remote rescue terminal device is installed is a fishing ship and the ship 2 on which the remote rescue terminal device is installed is a professional rescue ship, the rescue capacity of the ship 2 on which the remote rescue terminal device is installed is greater than that of the ship 1 on which the remote rescue terminal device is installed. After sorting based on the rescue ability of each ship, obtaining a ship sequence to filter ships with low rescue ability in the ship sequence based on historical experience, and obtaining a residual ship sequence. Calling historical rescue information of each ship in the remaining ship sequence, determining the maximum risk level corresponding to each ship in the remaining ship sequence according to the historical rescue information, and if the maximum risk level is larger than the risk level of the image information obtained through analysis, determining that the ship in the remaining ship sequence can rescue people falling into the water. In order to reduce the rescue time, the distance between the ship in the remaining ship sequence and the marine life-saving equipment can be acquired, so that the ship which can be rescued and is provided with the remote rescue terminal equipment is screened and determined in the remaining ship sequence based on the preset distance threshold value of the marine life-saving equipment.

Further, if the ship provided with the remote rescue terminal device cannot carry out rescue according to the risk level, the remote rescue terminal device sends feedback information of incapability of rescue to the marine life-saving equipment. At the moment, if the marine life-saving equipment cannot continuously receive rescue confirmation information returned by the remote rescue terminal equipment within a preset time interval, it indicates that ships with the remote rescue terminal equipment arranged around cannot rescue or ships with the remote rescue terminal equipment cannot rescue. At this time, in the embodiment of the present specification, in order to implement timely rescue for people falling into water with the marine life saving equipment, the marine life saving equipment sends the positioning information, the image information, and the risk level corresponding to the image information to the emergency rescue management center through RD communication. The rescue personnel who assists the emergency rescue management center determine professional rescue ships, helicopters, unmanned aerial vehicles and other equipment that can rescue the personnel falling into water, and the realization is to the timely rescue of the personnel falling into water.

In order to realize the overall description of the operation of the marine life-saving equipment, as shown in fig. 3, the present specification provides a workflow diagram of the triggering alarm of the marine life-saving equipment in one or more embodiments.

As can be seen from fig. 3, the marine life-saving equipment has two triggering modes of manual triggering and automatic triggering, and if the triggering mode is manual triggering, the power module is started to supply power to each module in the device after the manual triggering, so that the marine life-saving equipment enters a water falling alarm working state. If the passive pressure switch is in an automatic triggering mode, whether the pressure value of the passive pressure switch exceeds a threshold value or not needs to be judged, and whether the conductance value of the trigger electrode switch exceeds the threshold value or not needs to be detected. The switch will trigger conduction only if the pressure value of the passive pressure switch exceeds a threshold value and the conductance value detected by the trigger electrode switch also exceeds the threshold value. After the two switches are simultaneously switched on, the power supply module is started to supply power to each module of the equipment, so that the marine life-saving equipment enters a water falling alarm working state. The linkage trigger of the passive pressure switch and the water contact electrode switch is realized based on the mode, and compared with a trigger mode based on a single sensor, the mode improves the trigger reliability and reduces the probability of false trigger of equipment. After the marine life-saving equipment enters the drowning alarm working state, positioning and image acquisition are started, and positioning information and image information are reported at regular time. If the travelable rescue device provided with the remote rescue terminal device corresponding to the marine life-saving device is located in the rescue range and the travelable rescue device provided with the remote rescue terminal device has rescue capability, the marine life-saving device transmits the positioning information and the image information to the remote rescue terminal device through the wireless communication module. If the remote rescue terminal equipment corresponding to the marine life-saving equipment is not located in the rescue range or the remote rescue terminal equipment does not have rescue capacity, the marine life-saving equipment transmits the positioning information and the image information to the emergency rescue management center through the Beidou RD communication module. The rescue object with the rescue capacity can timely organize rescue work by transmitting the rescue object to the corresponding remote rescue terminal equipment or the emergency rescue management center through multiple communication transmission modes, and the rescue rate of people falling into water is improved.
