Technical Field

Background

When the existing marine life-saving equipment falls into water, the life-saving equipment is triggered to alarm and position generally based on the water-touching electrode switch, however, the existing water-touching electrode switch does not distinguish between sea water and fresh water, that is, does not distinguish between mediums contacted by the water-touching electrode switch, so that the existing equipment is easy to trigger by mistake due to the influence of weather environments such as rain, fog, dew and the like. In addition, in the existing mode, when the marine life-saving equipment is in alarm positioning based on the triggering of the water-triggering electrode switch, the possibility that the water-triggering electrode switch is in mistaken contact with the sea water due to wave splash or other objective reasons exists, and the problem of mistaken triggering of the marine life-saving equipment is further caused. In addition, when the pressure sensor is used for triggering the marine life-saving equipment to work, the pressure switch is easy to trigger by mistake or not due to lower sensitivity and poor reliability when the conventional life-saving equipment is triggered to work only by the passive pressure switch. The existing active pressure sensor has high precision, but needs to continuously supply power to the pressure sensor and the CPU to perform 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 offshore lifesaving equipment and an implementation method thereof.

With the development of fishery, maritime transportation industry and maritime transportation industry, maritime operators are increased year by year, and when the maritime operators work based on maritime operation ships and the like or perform other maritime transportation works, the maritime operators are often affected by marine climate and the like, so that the maritime operation ships, maritime transportation equipment and the like have the accidents of reef contact, collision, sinking and the like, and the maritime life-saving equipment is an important safety protection equipment for the maritime operators.

At present, the life-saving equipment adopted for people falling into water mainly comprises life jackets, life rings, life ropes, inflatable rubber rafts, life stretchers and the like. However, after the conventional life-saving equipment falls into water, due to the lack of a positioning and position reporting device, the rescue aircraft or ship is difficult to find the position of people in danger, and the 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. The marine life-saving equipment with the positioning device generally triggers the life-saving equipment to alarm and position by touching the water switch or triggers the life-saving equipment to alarm and position by touching the pressure switch after the personnel falls into water. However, when the lifesaving equipment is triggered to alarm and position only based on the water-contact electrode switch, the current water-contact electrode switch does not distinguish the contacted medium, so that the current lifesaving equipment triggered based on the water-contact electrode switch often causes false triggering of the equipment due to the influence of weather environments such as rain, fog, dew and the like, and the reliability is poor. The pressure switch comprises a passive pressure switch and an active pressure switch, wherein the existing passive pressure switch has the problems of large volume, low sensitivity, poor reliability and the like, and the conduction threshold is a range interval, cannot be accurate to a fixed value, and is easy to cause false triggering or non-triggering of the pressure switch. The active pressure sensor has high precision, but the pressure sensor and the CPU are required to be continuously powered, so that pressure detection and threshold judgment are carried out, and the standby power consumption of the marine life-saving equipment is increased.

In order to solve the technical problems, the embodiment of the specification provides an offshore rescue device and an implementation method thereof, and the location of the offshore rescue device is determined through a location module in the offshore rescue device, so that the problem that the conventional rescue device cannot acquire the location information of people falling into water, and rescue of the people falling into water is difficult is solved. The adoption has the touch water electrode switch that a plurality of electrode electric conductance detected, only the mode that just confirms the trigger when continuously touching the sea water has solved current touch water electrode switch and has not distinguished the medium that it contacted, often can lead to equipment misinformation because of the influence of weather environment such as rain fog, dew. The problem that the current on threshold value is a range interval based on the passive pressure switch or the active pressure switch and cannot be accurate to a fixed value is solved by determining whether to trigger based on the contraction amount by the passive pressure sensor, and the problem that the active pressure switch needs to be powered continuously is solved. Meanwhile, based on the linkage mode of the water-touching electrode switch and the passive pressure switch, the problem of lower triggering reliability when the water-touching electrode switch is triggered only or only, and the false alarm rate of the marine life-saving equipment is reduced.

In order to make the technical solutions in the present specification better understood by those skilled in the art, 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 some embodiments of the present specification, not all embodiments. All other embodiments, which can be made by one of ordinary skill in the art based on the embodiments herein without making any inventive effort, shall fall within the scope of the present disclosure.

As shown in fig. 1, the embodiment of the present specification provides a schematic structural view of an offshore rescue apparatus. As can be seen from fig. 1, the 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 equipment also comprises a power supply module which wakes up the control processing module and provides electric energy for the positioning module and the communication module, a water-touching electrode switch and a passive pressure switch which are triggered in a linkage way to control the power supply module to be started, and the water-touching electrode switch and the passive pressure switch which are triggered in a linkage way are used for waking up the control processing module to perform positioning alarm based on the linkage way, and the water-touching electrode switch with a plurality of electrode conductivity detection and the passive pressure switch are combined in a linkage way, so that the water-touching alarm can be triggered automatically only under the condition of meeting certain conductivity value and pressure simultaneously. The problem of high power consumption caused when the marine life-saving equipment is in a working state at any time is avoided, and meanwhile, the problem of unreliability caused by triggering of a single sensor is avoided through linkage triggering of the water-touching electrode switch and the passive pressure switch.

The passive pressure switch is composed of an isolation diaphragm and a pre-tightening elastic element. The water-contact 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 offshore lifesaving equipment at equal intervals and are covered and protected through nonmetal. For example: taking the example that the water-contact electrode switch is applied to the life-saving equipment on the sea, under a certain application scene of the specification, the water-contact electrode switch comprises four detection electrodes of the seawater erosion resistant gold-plating 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 offshore lifesaving equipment, the periphery 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 changed from double-electrode detection to multi-electrode detection, and the problem that the water-contact electrode switch is easily triggered by mistakes caused by objective factors such as splashing seawater is solved. In addition, it should be noted with reference to fig. 1 that the control processing module in the offshore lifesaving device can be used for device control and data communication, so as to realize functions of initializing, parameter setting, positioning and communication data processing, information interaction, flashing of the strobe module, photographing of the camera and the like of the positioning module, the communication module and the like.

The existing water-contact electrode switch does not distinguish the contacted medium, so that the problem that the water-contact electrode switch is triggered by mistake in rainy and foggy weather is easily caused, and the problem that the water-contact electrode switch is unreliable is further caused. To solve this problem, in one or more embodiments of the present disclosure, a water-contacting electrode switch is used to obtain a conductivity value of a current medium, and obtain a mutual distance between electrodes and a cross-sectional area of each electrode in the water-contacting electrode switch, and then determine the current conductivity value between each electrode of the water-contacting electrode switch according to the conductivity value of the current medium obtained by the water-contacting electrode switch, the mutual distance between each electrode and the cross-sectional area of the electrode. And if the current conductivity value of each electrode is determined to be greater than the preset conductivity value threshold value, triggering the water-contact electrode switch, so that the water-contact electrode switch is closed. When the marine life-saving equipment is used, the problem that the conductivity value of the water-contacting electrode switch in the marine life-saving equipment is greatly different between the seawater and the fresh water is considered, so that the water-contacting electrode switch can obtain the current conductivity value between the electrodes based on the combination of the current conductivity value of the medium, the mutual distance between the electrodes in the water-contacting electrode switch and the sectional area of each electrode, and further judge whether the water-contacting electrode is triggered or not, and the false triggering problem 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 pre-tensioned elastic element. After the offshore lifesaving device falls into water, water pressure is transmitted to the pre-tightening elastic element through the isolating diaphragm in the passive pressure switch, and when the water pressure exceeds a preset conduction pressure threshold value, the switch is triggered. 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 in the process. If the shrinkage of the pre-tightening elastic element is determined to be larger than the preset shrinkage threshold value, and the elastic coefficient of the pre-tightening elastic element is determined to be smaller than the preset elastic coefficient threshold value, determining that the current water pressure of the passive pressure switch is larger than the preset conducting pressure threshold value, and triggering the closing of the passive pressure switch.

Further, in one or more embodiments of the present disclosure, as shown in fig. 1, the communication module includes: the wireless communication module, the Beidou RD communication module, the wireless communication module antenna and the Beidou positioning communication antenna; the positioning module comprises: beidou RN positioning module. The wireless communication module is electrically connected with the control processing module and is 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 positioning information of the marine life-saving equipment and image information acquired by the acquisition equipment to the remote rescue terminal equipment through the short-distance communication. The Beidou positioning communication antenna is used for receiving Beidou satellite signals in the Beidou RD communication module and a preset Beidou communication system, for example: for receiving the Beidou satellite positioning signals, receiving the Beidou satellite outbound signals and transmitting the Beidou satellite inbound signals, the Beidou positioning communication antenna is a three-in-one multi-frequency combined antenna.

The Beidou RD communication module is electrically connected with the control processing module and used for communicating with a preset Beidou communication system through a Beidou positioning communication antenna after the control processing module wakes up, and acquiring positioning information of the marine life-saving equipment according to double-star active positioning. This big dipper RD communication module communicates concrete process through big dipper location communication antenna and default big dipper communication system: 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 out the signals through a Beidou positioning communication antenna; and the system is used for amplifying, down-converting, pseudo code capturing, tracking, despreading, carrier recovery, demodulation and decoding of the Beidou satellite outbound signals received by the Beidou positioning communication antenna to obtain information of the outbound signals. And the Beidou RN positioning module is connected with the Beidou positioning communication antenna and is 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 successfully started, and obtaining positioning information of the marine life-saving equipment after amplifying, down-converting, capturing, tracking, despreading, decoding and positioning resolving the satellite signals.

Further, in one or more embodiments of the present description, as shown in fig. 1, the marine life-saving apparatus 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. The infrared camera is used for acquiring image information according to an acquisition instruction of the control processing module, facial features of people falling into water and surrounding environments of the people falling into water can be shot at fixed time through preset frequency, and then the image information is sent to the remote rescue terminal equipment through the wireless communication module in the marine rescue equipment or sent to the emergency rescue management center through the RD communication module, so that the remote rescue terminal equipment or the emergency rescue management center can acquire vital sign judgment and surrounding environments of the people falling into water, and accordingly a proper rescue mode can be conveniently analyzed to timely rescue the people falling into water. The stroboscopic module adopts a special driving chip for LEDs, is matched with low-power high-brightness LED lamp beads, and is used for alarming and flashing according to an alarming instruction of the control processing module. After the strobe module triggers the offshore lifesaving equipment to run, under the control of the control processing module, the illumination intensity of the environment where the current person falls into water is detected through a photosensitive sensor built in the strobe module, if the current illumination intensity is smaller than a preset illumination intensity threshold value, the strobe module is started, that is to say, the strobe module is started only when the illumination intensity is smaller than the preset threshold value, and performs flashing alarm display according to the set frequency, and the rest time period is closed. The following description is needed: the resistance of the photosensitive sensor is inversely related to the illumination intensity, and the weaker the illumination intensity is, the larger the resistance is. When the light sensor is manually or automatically in a water falling positioning alarm working state, the light sensor detects the external illumination intensity and displays different resistance values according to different illumination intensities, and when the resistance value of the light sensor is larger than a set threshold value, the light intensity is smaller than the set illumination threshold value, and the strobe module is started at the moment. By means of the flicker alarm mode after the illumination intensity threshold value is judged, the effect that the positions of people falling into water are rapidly determined by surrounding rescue ships under the condition of low illumination is achieved. Meanwhile, the strobe module determines the accumulated working time according to the flicker starting time and the current time, and if the accumulated working time is determined to be larger than the preset time threshold, the flicker frequency of the strobe module is reduced in order to save the electric quantity of the offshore lifesaving equipment. For example: when the preset time period is 8 hours, if the accumulated working time is determined to reach 8 hours based on the starting time and the current time of the flicker, the flicker frequency of the strobe module can be reduced from 1 second/time to 5 seconds/time in order to save the electric quantity of the terminal. The stroboscopic module in the embodiment of the specification 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 illumination intensity and reducing flicker frequency based on accumulated working time.

As shown in fig. 2, the embodiment of the present specification provides a method for implementing an offshore lifesaving device, the method including the following steps;

s201: the water-contacting electrode switch obtains the current conductivity value between the electrodes so that the water-contacting electrode switch determines whether to trigger closing or not based on the current conductivity value.

Firstly, in order to avoid the false triggering problem caused by the fact that the water-touching electrode switch is in short time contact with sea water, for example, the false triggering of the water-touching electrode switch caused by splash during offshore operation is avoided. In the embodiment of the specification, the current conductivity value among the electrodes is obtained by the water-contact electrode switch, so that the triggering of the water-contact electrode switch is determined after the current conductivity value among the electrodes is judged in a combined mode, the condition that the offshore lifesaving equipment can give an alarm only when the offshore lifesaving equipment continuously contacts seawater is ensured, and the reliability of the water-contact electrode switch is improved.

Further, the current-contact water electrode switch cannot distinguish the media, and is easily affected by rain weather in some cases, so that the false alarm rate is high. In one or more embodiments of the present disclosure, the current conductance value between the electrodes is obtained by the water-contacting electrode switch, so that the water-contacting electrode switch determines whether to trigger closing based on the current conductance value, specifically including the following procedures:

Firstly, since the conductivity value C of seawater is between 5 and 50ms/cm, and the conductivity value c=0.05 to 1ms/cm of fresh water is significantly different, the conductivity values of seawater and fresh water also have a great difference value. In the embodiment of the present disclosure, the water-contact electrode switch firstly obtains the conductivity value C of the current medium, and obtains the mutual distance L between the electrodes and the sectional area S of each electrode in the water-contact electrode switch. And then the water-contact electrode switch determines the current conductivity value G of the water-contact electrode switch according to the conductivity value C of the current medium, the mutual distance L between the electrodes and the sectional area S of the electrodes. That is to say according to the formulaA current conductance value of the water-contacting switch is determined. For example: the conductivity value C of the fresh water is between 5 and 50ms/cm, and the conductivity value C of the fresh water is between 0.05 and 1ms/cmThe mutual distance L=2 cm between the electrodes, and the sectional area A=0.1 cm2 is exemplified, then the medium is seawater, and the conductivity value is +.> I.e. the resistance is r=1/g=400 Ω -4 kΩ. If the medium is fresh water, the electric conductivity is +.>I.e. the resistance value is r=1/g=20kΩ -400 kΩ. According to the above process, if the current conductivity value is determined to be greater than the preset conductivity value threshold, the water-contact electrode switch is triggered, so that the water-contact electrode switch is closed.

Specifically, in one or more embodiments of the present disclosure, if it is determined that the current conductivity value is greater than the preset conductivity value threshold, the water-contacting electrode switch is triggered to be closed, which specifically includes the following procedures: and the water-touching electrode switch is triggered if the current conductivity value between the electrodes is determined to be larger than the preset conductivity threshold value. The current conductivity value between the electrodes is triggered to give an alarm, so that the marine life-saving equipment can be triggered only when the marine life-saving equipment is continuously contacted with seawater, and the triggered reliability of the water-contact electrode switch is improved. In addition, the setting of the conductivity threshold is related to the medium where the marine life saving equipment is located, and the conductivity threshold of the water-contacting electrode switch can be set to be 0.1ms when the conductivity value is more than 0.1ms, namely the resistance value is less than 10kΩ because the seawater conductivity value is between 0.25 ms and 2.5ms and the fresh water conductivity value is between 0.0025 ms and 0.05 ms. Because the conductivity value of the seawater is far greater than the set threshold value of 0.1ms, and the conductivity value of the fresh water is far less than the set threshold value of 0.1ms, the problem that the underwater marine life-saving equipment is triggered in rainy and foggy days can be avoided.

S202: the passive pressure switch obtains the shrinkage of the pre-tightening elastic element to determine whether to trigger the closing of the passive pressure switch based on the shrinkage of the pre-tightening elastic element.

The passive pressure switch mainly comprises an isolation diaphragm and a pre-tightening elastic element. After the offshore rescue equipment falls into water, water pressure is transmitted to the pre-tightening elastic element through the isolating 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 contraction amount 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 contraction amount.

Further, to ensure that the passive pressure switch is able to trigger closing after the pre-tensioned elastic element reaches a certain amount of contraction, in one or more embodiments of the present disclosure, the passive pressure switch obtains the amount of contraction of the pre-tensioned elastic element to determine whether to trigger closing of the passive pressure switch before the amount of contraction of the pre-tensioned elastic element is determined, the method further comprises the steps of:

firstly, the passive pressure switch needs to acquire a preset alarm depth D, the density ρ of a medium in which the passive pressure switch is currently located and the surface area S of an isolation diaphragm in the passive pressure switch, so that a preset conducting pressure threshold 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/cm 3, the gravity coefficient g=9.8N/kg, and the alarm depth D=20cm, when the water depth D=20cm, the water pressure born by the isolation diaphragm is the preset conducting pressure threshold value, and the following calculation formula of the preset conducting pressure threshold value is shown:

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

From the above, after the marine life-saving equipment falls into water, the water pressure is transmitted to the pre-tightening elastic element through the isolating diaphragm in the passive pressure switch, the elastic force f2=kxΔx, k of the pre-tightening elastic element is the elastic coefficient, Δx is the shrinkage of the pre-tightening elastic element, so that the passive pressure switch can trigger under the corresponding depth and water pressure, and the passive pressure switch is passiveThe pressure switch needs to acquire a first relative distance between the metal disc and the electrode in the pre-tightening elastic element under the non-pressure condition, and simulate and acquire a second relative distance between the metal disc and the electrode under the preset conducting pressure threshold value. And obtaining a shrinkage threshold of the pre-tightening elastic element under a preset conducting pressure threshold according to the first relative distance and the second relative distance. And then the passive pressure switch determines the elastic coefficient threshold value of the pre-tightening elastic element in the passive pressure switch according to the contraction 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. The above examples are given: when the relative distance d=0.1 cm between the metal disc and the electrode is set, and when the shrinkage threshold DeltaX=0.1 cm of the pre-tightening elastic element, the elastic force F2 of the pre-tightening elastic element is smaller than the pressure F1 of the isolation diaphragm, and the pressure switch can be triggered when the water depth is 20 cm. The coefficient of elasticity can be calculated I.e. the modulus of elasticity threshold is 196N/m.

Specifically, in one or more embodiments of the present disclosure, the passive pressure switch obtains a contraction amount of the pre-tightening elastic element to determine whether to trigger closing of the passive pressure switch based on the contraction amount of the pre-tightening elastic element, including specifically the following procedures:

first, the passive pressure switch acquires the contraction amount of the pre-tightening elastic element and the elastic coefficient of the pre-tightening elastic element. If it is determined that the contraction amount of the current pre-tightening elastic element is larger than the preset contraction amount threshold value and the elastic coefficient of the pre-tightening elastic element is smaller than the preset elastic coefficient threshold value, it is determined that the current water pressure of the passive pressure switch is larger than the preset conduction pressure threshold value, and the passive pressure switch can be triggered at the moment, so that the passive pressure switch is closed.

S203: and if the water touch 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 for all the modules in the marine life-saving equipment.

Based on the step S201 and the step S202, if both the water-contact electrode switch and the passive pressure switch are triggered, so that both the water-contact electrode switch and the passive pressure switch are in a closed state, the power module of the offshore rescue equipment is turned on, so that the power module wakes up the control processing module and supplies power to each module in the offshore rescue equipment, and the offshore rescue equipment is in a working state. In the embodiment of the specification, after the offshore lifesaving equipment falls into water, a water touch switch and a passive pressure switch adopting multi-electrode conductivity detection are automatically triggered. Through the mode of linkage triggering for marine life-saving equipment only satisfies under the condition of certain conductivity value and pressure simultaneously, touch water switch and passive pressure switch and trigger simultaneously, power module gives big dipper RN positioning module, big dipper RD communication module, wireless communication module, control and processing module, stroboscopic module, the power supply loop of CMOS infrared camera just can be opened, and marine life-saving equipment just can begin to trigger automatically and fall into water the warning, has solved current touch water electrode switch and has easily received the shortcoming that weather environment influences such as rain fog, dew, wave splash lead to the false triggering, and current pressure switch sensitivity is low, the reliability is poor, the shortcoming of easy false triggering or not triggering. In addition, it should be noted that the offshore rescue equipment in the embodiment of the specification can be manually started, the power module skips the threshold detection of the water touch switch and the passive pressure switch, and is forced to power up each module to enter a manual triggering water falling alarm working state. The device can be turned off manually, so that the alarm is forcibly released and the device is turned off, and the adaptability of the marine life-saving device is improved.

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

After supplying power 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 water corresponding to the marine life-saving equipment. And controlling the infrared camera to acquire image information so as to analyze the sign information and the surrounding environment information of the person falling into water based on the image information, thereby determining a corresponding rescue scheme according to the sign information and the surrounding environment information. Meanwhile, in order to facilitate surrounding ships or other rescue equipment to lock water falling personnel corresponding to the marine rescue equipment under the condition of low illumination, the strobe module adopts an LED special driving chip and is matched with a low-power high-brightness LED lamp bead to carry out alarm flickering according to an alarm instruction of the control processing module. And in combination with the description of the strobe module in the above-mentioned marine life-saving equipment, the strobe module in the embodiment of the present disclosure can greatly reduce the average working power consumption of the marine life-saving equipment and extend the endurance time of the marine life-saving equipment by combining two methods of controlling strobe opening based on illumination intensity and reducing flicker frequency based on accumulated working time.

Specifically, in one or more embodiments of the present disclosure, the control processing module obtains positioning information of the offshore rescue device based on a beidou RD communication module or a beidou RN positioning module in the offshore rescue device, and specifically includes the following procedures:

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, and whether the Beidou RN positioning module is started successfully is determined. If the Beidou RN positioning module is determined to be successfully started, 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, so that positioning information of the marine life-saving equipment is obtained according to positioning calculation of the Beidou RN positioning module on the satellite signals. If the positioning information is unsuccessful, in order to avoid the problem that rescue time caused by the RN positioning starting time process is prolonged, rescue time of people falling into water is saved, and the control processing module acquires positioning information of a preset Beidou communication system transmitted by a Beidou positioning communication antenna connected with the Beidou RD communication module according to the Beidou RD communication module. After the Beidou RD communication module sends active positioning to the Beidou communication system through the Beidou positioning communication antenna, a 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 the Beidou RD communication module through the Beidou satellite, so that the position of the marine life-saving equipment is rapidly obtained. In the process, the first capturing time of the RD communication module is calculated, the time delay of sending positioning request information to the ground central station, the time length of solving the position information by the ground central station and the time delay of sending the position information to the RD communication module by the ground central station are calculated, the whole RD active positioning time is not more than 3S, compared with the RN cold start first positioning time of 40-60S, the cold start positioning time is effectively reduced, the real-time performance of the whole system is improved, and therefore the timeliness of acquiring the position of the marine life saving equipment is effectively improved in a combined mode through two positioning modes, and the life saving rate of people falling into water is further improved.

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

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 specification sends the positioning information and the image information to the corresponding remote equipment based on the communication module so as to help the person falling into water using the marine life-saving equipment.

Further, in one or more embodiments of the present disclosure, in extreme weather, the person falling into water using the marine life saving device may cause the lifting of the rescue risk to cause that the ship with the remote rescue terminal equipment partially installed cannot rescue the person falling into water, so that effective rescue for the person falling into water is achieved on the premise of ensuring the safety of the ship. In the embodiment of the specification, the offshore lifesaving device firstly acquires the image information acquired by the acquisition device, and inputs the image information into the deep learning network model, so that the risk type contained in the image information is identified based on the deep learning network model, and then a plurality of risk influence factors corresponding to the risk type in the image information are acquired according to a preset risk condition table, so that the risk grade corresponding to the risk type is predicted based on the plurality of risk influence factors. After the risk level corresponding to the image information is obtained, the offshore rescue 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 obtained by the offshore rescue equipment in the process are sent to a ship with the remote rescue terminal equipment in the effective coverage area through the built-in wireless communication module. The ship with the remote rescue terminal equipment installed in the effective coverage area is conveniently subjected to rescue, and whether rescue is carried out or not is determined according to the risk level corresponding to the image information. If it is determined that rescue can be performed, the remote rescue terminal equipment transmits rescue confirmation information to the marine rescue equipment, and the ship provided with the remote rescue terminal equipment performs rescue. If rescue is not possible, the remote rescue terminal equipment sends feedback information of the rescue failure to the marine rescue equipment.

It should be noted that, in the embodiment of the present disclosure, in order to increase the image features of the image information acquired by the offshore rescue device, so as to improve the accuracy of model identification image, before inputting the image information into the deep learning network, the method further includes the following steps: firstly, dividing an initial image acquired by an acquisition device into a plurality of subareas according to a preset dividing area, so as to obtain the plurality of subareas of the initial image. In order to facilitate highlighting special information contained in an image and avoid the problem that detail influence factors cannot be determined due to the fact that seawater and sky colors are too close, after a plurality of subareas of an initial image are acquired, binarization processing is carried out on the subareas according to a preset binarization threshold value, so that a binarization image of the initial image is obtained. And then, in order to remove noise data in the image, each image pixel point in the binarized image of the initial image is subjected to weighting processing through a preset filter check, so that noise filtering of the binarized image of the initial image is realized, and a processed image is obtained. The method is convenient for the offshore lifesaving equipment to input and transmit the processed image to a preset deep learning network model for recognition, and the risk types contained in the image information are output, so that a plurality of risk influence factors corresponding to the risk types are obtained according to a preset risk condition table.

Further, in the embodiment of the present disclosure, predicting, based on the multiple risk impact factors, a risk level corresponding to a current risk type includes the following steps: and inputting the multiple 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 embodiment of the present disclosure, in order to improve the reliability and accuracy of the prediction of the vector machine model, each parameter in the improved algorithm corresponding to the vector machine model is first obtained, and each parameter is initialized. It should also be noted that the parameters in the improved algorithm include: forward population size of forward search particles, maximum number of iterations, inertial weights, etc. And initializing a forward population formed by the forward search particles according to a preset reverse learning mechanism to obtain the coordinate positions of the reverse search particles in the 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, in the embodiment of the present disclosure, a preset fitness function is obtained, so that 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 will be appreciated that the smaller the fitness value, the better the outcome of the prediction. And randomly generating a random number in a preset range, determining the coordinate position of the search particle in the current search population based on the value of the random number, and obtaining the position information corresponding to the search particle with the minimum fitness value through iterative calculation, so as to determine the optimal parameter of the preset least square support vector machine model meeting the requirements based on the position information. And then the vector machine model is adjusted and improved according to the optimal model parameters, and an optimized vector machine model is obtained, so that the prediction accuracy of the risk level of the risk type is improved.

From the above, it can be understood that if the current risk level is greater than the risk that the ship with the remote rescue terminal device can bear, the ship with the remote rescue terminal device cannot rescue the person falling into water. Therefore, in one or more embodiments of the present disclosure, the determination of whether to rescue is performed according to the risk level corresponding to the image information of the ship in which the remote rescue terminal device is installed in the effective coverage area specifically includes the following steps.

Basic information of each ship equipped with the remote rescue terminal equipment is first acquired. Wherein, it should be noted that the basic information includes: the type of the ship, the total carrying capacity, the number of crew members, the number and the type of rescue equipment. And comparing basic information of each ship provided with the remote rescue terminal equipment so as to sort rescue capabilities of each ship. For example: based on the type of the ship 1 mounted with the remote rescue terminal equipment and the ship 2 mounted with the remote rescue terminal equipment, if it is determined that the ship 1 mounted with the remote rescue terminal equipment is a fishing boat and the ship 2 mounted with the remote rescue terminal equipment is a professional rescue ship, the rescue capacity of the ship 2 mounted with the remote rescue terminal equipment is greater than that of the ship 1 mounted with the remote rescue terminal equipment. After sorting based on the rescue capabilities of the individual vessels, a sequence of vessels is obtained to filter vessels of low rescue capabilities in the sequence of vessels based on historical experience, obtaining a sequence of remaining vessels. And calling historical rescue information of each ship in the residual ship sequence, determining the maximum risk level corresponding to each ship in the residual ship sequence according to the historical rescue information, and if the maximum risk level is greater than the risk level of the image information obtained by the analysis, determining that the ship in the residual ship sequence can rescue people falling into water. In order to reduce the rescue time, the distance between the ship in the residual ship sequence and the marine life-saving equipment can be acquired, so that the ship with the remote rescue terminal equipment, which can be used for rescue, is screened and determined from the residual ship sequence based on the preset distance threshold value of the marine life-saving equipment.

Further, if it is determined that the ship provided with the remote rescue terminal equipment cannot rescue according to the risk level, the remote rescue terminal equipment sends feedback information of the incapacity of rescue to the marine rescue equipment. At this time, if the marine life-saving equipment continuously receives no rescue confirmation information returned from the remote rescue terminal equipment within a preset time interval, it indicates that the ship around which the remote rescue terminal equipment is installed cannot rescue, or that the ship on which the remote rescue terminal equipment is installed does not exist, so that rescue cannot be performed. At this time, in the embodiment of the present disclosure, in order to achieve timely rescue for the person falling into water with the offshore rescue device, the offshore rescue device 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 of the auxiliary emergency rescue management center determine equipment such as professional rescue ships, helicopters, unmanned aerial vehicles and the like which can rescue the personnel falling into water, so that timely rescue of the personnel falling into water is realized.

To achieve an overall description of the operation of an offshore rescue device, as shown in fig. 3, one or more embodiments of the present specification provide a schematic workflow diagram of an offshore rescue device triggering an alarm.

As can be seen from fig. 3, the offshore lifesaving device has two triggering modes, i.e. manual triggering and automatic triggering, and if the manual triggering is performed, the power module is started to supply power to each module in the device after the manual triggering, so that the offshore lifesaving device enters a water falling alarm working state. If the automatic triggering mode is adopted, whether the pressure value received by the passive pressure switch exceeds a threshold value or not needs to be judged, and whether the conductivity value detected by the water triggering electrode switch exceeds the threshold value or not is judged. 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 water-touching electrode switch also exceeds a threshold value. After the two switches are simultaneously conducted, the power supply module can be started to supply power to each module of the equipment, so that the offshore lifesaving equipment enters a water falling alarm working state. Based on the mode, linkage triggering of the passive pressure switch and the water-triggering electrode switch is realized, and compared with a triggering mode based on a single sensor, the mode improves the triggering reliability and reduces the false triggering probability of equipment. After the marine life-saving equipment enters a water falling alarm working state, positioning and image acquisition are started, and positioning information and image information are reported at fixed time. If the drivable rescue equipment provided with the remote rescue terminal equipment corresponding to the marine rescue equipment is located in the rescue range and the drivable rescue equipment provided with the remote rescue terminal equipment has rescue capability, the marine rescue equipment transmits positioning information and image information to the remote rescue terminal equipment through the wireless communication module. If the remote rescue terminal equipment corresponding to the marine rescue equipment is not located in the rescue range or the remote rescue terminal equipment does not have rescue capability, the marine rescue equipment transmits positioning information and image information to the emergency rescue management center through the Beidou RD communication module. The rescue target with the rescue capability can organize rescue work in time by transmitting the rescue target to corresponding remote rescue terminal equipment or an emergency rescue management center in various communication transmission modes, so that the rescue rate of people falling into water is improved.
