Detailed Description
In order to make the aforementioned objects, features and advantages of the present invention comprehensible, embodiments accompanied with figures are described in detail below.
Due to the particularity of the search and rescue work at sea, many difficult problems always bother the development and the improvement of the success of the search and rescue work, and the specific conditions are as follows: (1) the man falling into the water is difficult to position: at sea, after people fall into water, because the search and rescue center does not carry modern positioning equipment with the people, the search and rescue center is difficult to accurately position and track the people falling into water, and particularly, the specific position of the people falling into water can hardly be mastered at night or in severe weather such as heavy storms, heavy fog and the like, so that search and rescue decision and action development are seriously influenced.
(2) The man falling into the water is difficult to search: targets of people falling into the water are small in the sea and are difficult to find in the usual stormy weather on the sea; meanwhile, under the influence of wind, waves, current and tides, the position of people falling into water can change at any time, so that it is difficult for ships and airplanes to search people falling into water like a sea fishing needle, and people falling into water are difficult to search quickly in time.
(3) The search and rescue efficiency of the personnel falling into water is low: according to the statistics of the international maritime organization, most people falling into water at sea are frozen or thirsty, but not drowned. When the water temperature is 0 ℃, the survival time of people falling into water is about 15 minutes; 10 ℃ for about 3 hours and 20 ℃ for about 40 hours, so that the device is very important for people falling into water to accurately position and quickly, effectively and accurately deploy rescue actions. However, at present, people falling into water are difficult to locate and search, and cannot rapidly rescue the water to lose life, so that the rescue probability of people falling into water is quite small, and the rescue success rate is continuously low. In addition, even after the person falling into the water dies, the body of the victim cannot be searched, and the victim cannot be pacified.
(4) The cost of personnel falling into water for search and rescue is large: because the target of the person falling into the water is small, the position changes rapidly, the person falling into the water needs to organize a large number of ships and airplanes to implement three-dimensional searching usually, and due to the influence of adverse factors such as severe weather, searching and rescuing actions mostly last for multiple days, and the cost for direct searching and rescuing is very high.
In recent years, the Beidou satellite positioning system in China is continuously mature and is developed into one of four global satellite positioning systems. The prior open Beidou system has an uplink low frequency of 1610-1626.5MHz and a downlink high frequency of 2483.5-2500 MHz. Compared with the current GPS system which occupies the dominant market position, the Beidou system has unique advantages. The GPS system has the dual functions of positioning and communication, does not need the support of other communication systems, and can only position.
The unique bidirectional communication function and the accurate positioning system of the Beidou satellite lay a solid foundation for emergency search and rescue in China. It has the characteristics of small quantity of satellites, small investment, simple user equipment, low price, low operation communication cost and the like. Big dipper satellite navigation has powerful function in the aspect of communication location, mainly includes: the Beidou satellite navigation system has the functions of positioning and communication at the same time, and does not need the support of other communication systems; the Beidou satellite navigation system covers China and surrounding countries and regions, is served for 24 hours all weather, has no communication blind area and basically has no time delay; the Beidou satellite navigation system is particularly suitable for large-scale monitoring and management of group users and data transmission application of data acquisition users in unsupported areas; the unique central node type positioning processing and command type user machine design of the Beidou satellite navigation system can simultaneously meet the requirement of bidirectional positioning.
To this end, referring to fig. 1 to 5, an embodiment of the present invention provides a lifesaving apparatus 10 including: a housing, the housing being cuboid; the number of the self-locking switches 30 is at least two, the self-locking switches 30 are arranged on the outer surface of the shell, and the shell is connected with the self-locking switches 30 in a sealing mode; the Beidou communication terminal 20 is arranged in the shell and located at the foremost end of the shell, and when the user uses the lifesaving equipment and holds the lifesaving equipment, the foremost end faces the Beidou satellite and is used for communicating with the Beidou satellite (not shown) and sending position information to the outside.
The shape of the housing of the life saving equipment 10 is not limited, and may be a square shape, a cylindrical shape, or the like in other embodiments.
In this embodiment, the self-locking switch 30 controls the on/off of the Beidou communication terminal 20; the self-locking switch 30 is a common button switch; the self-locking switch 30 is turned on and held from being pressed to being sprung for the first time, and the self-locking switch 30 is turned off from being pressed and bouncing again for the second time.
In this embodiment, self-locking switch 30 has a plurality ofly, and self-locking switch 30 controls opening of big dipper communication terminal 20 through following mode, and in this embodiment, self-locking switch 30 is the column: all the self-locking switches 30 are pressed down and bounced according to a set sequence and then send out starting signals, wherein each self-locking switch is pressed down at intervals for a set time and then bounced; the Beidou communication terminal receives the opening signal and then communicates with the Beidou satellite, and the Beidou communication terminal 20 is in an opening state; for example, the set time is 50s to 60s, including 50s and 60 s; otherwise, the beidou communication terminal 20 is in the off state.
Even if the deepwater operator accidentally touches the self-locking switch 30, the self-locking switch 30 is pressed down and bounced for a short time, and the self-locking switch 30 is not pressed down and bounced according to the set sequence, and the interval time between the pressing down and the bounced of the self-locking switch 30 is short; therefore, the Beidou communication terminal 20 cannot be in an open state due to misoperation of deepwater operators, and the safety and reliability of the lifesaving equipment are improved. Wherein, the deepwater operator can be a diver or a seabed salvage person or other persons working underwater.
Thus, when the deepwater operator is in danger, a certain time is needed for the deepwater operator to swim from underwater to water, when the deepwater operator is underwater, the self-locking switch 30 is pressed for the first time and is kept in a pressed state, at the moment, the Beidou communication terminal 20 does not work, in the embodiment, the self-locking switch is provided with the first contact 31, the Printed Circuit Board (PCB) 70 built in the lifesaving equipment is provided with the second contact 71, when the self-locking switch is pressed, the first contact 31 is in contact with the second contact 71, and the lifesaving equipment cannot work when the first contact 31 is set to be in contact with the second contact 71 through the arrangement of the PCB 70.
When the deepwater operator swims from the water to the water, the self-locking switch 30 can be automatically bounced under the action of atmospheric pressure difference at the moment when the deepwater operator goes out of the water (about 55s is needed in the process), and a spring (not shown) is arranged between the self-locking switch and the shell, so that the self-locking switch 30 is bounced according to a set sequence, the elastic coefficient of the spring needs to be set correspondingly; thus, under the action of the pressure difference, the self-locking switch 30 is bounced according to the set sequence because the elastic coefficients of the springs are different and the elastic force applied by the springs to the self-locking switch 30 is also different; when the self-locking switch is bounced, the first contact 31 is separated from the second contact 71, the PCB 70 is arranged, the self-locking switch sends an opening signal when the first contact 31 is separated from the second contact 71, the Beidou communication terminal 20 receives the opening signal to start communication, and the lifesaving equipment is in a working state.
Therefore, when the deepwater workers come out of the water, the self-locking switches 30 are pressed down and then bounced according to the set sequence, each self-locking switch 30 is pressed down and then bounced after the set time interval, the Beidou communication terminal 20 is in the open state, the Beidou communication terminal 20 starts to work, position information and a distress signal are continuously sent out, the rescue center receives the distress signal sent by the lifesaving equipment worn by the deepwater workers, the position of the deepwater workers is judged, and rescue work is carried out.
In addition, because the deepwater worker can wear gloves, the self-locking switch 30 is inconvenient to operate, and the self-locking switch 30 of the embodiment can be automatically opened by using pressure difference, so that great convenience is brought to the deepwater worker to use the lifesaving equipment.
In this embodiment, the housing has a first outer surface 11 for facing the beidou satellite, and a window 60 is provided on the first outer surface 11; the deepwater operator can also check the running state of the lifesaving equipment and the position information of the deepwater operator through the window 60. By adopting the lifesaving equipment of the embodiment, the Beidou communication terminal is not in the open state due to misoperation of deepwater operators, and the safety and reliability of the lifesaving equipment are improved.
The Beidou communication terminal 20 in the embodiment can provide information such as position, short message communication, time and the like by applying a Beidou satellite navigation system in China, and can realize positioning, navigation, monitoring and scientific management of various carriers of the Beidou communication terminal; the lifesaving equipment can enable the deepwater operators to carry out short message communication with the search and rescue center and report the positioning information, thereby providing quick and accurate information support for rescuing the deepwater operators in danger; is a revolutionary innovative measure for the existing search and rescue mode, and can comprehensively solve the problem of long-term trouble search and rescue work on sea (water) such as difficult positioning, difficult search, low search and rescue efficiency and the like of deepwater operators in danger. In the search and rescue operation, the search and rescue center only needs to organize a ship or an airplane to perform linear search and rescue on deep-water operators according to the positions of the deep-water operators in danger and the distribution condition of peripheral search and rescue forces, so that the original net-pulling type search and rescue mode of ship-sea search and rescue tactics is changed, unnecessary search and rescue force organization and search and rescue resource participation are reduced, and the direct cost of search and rescue is greatly saved.
It should be noted that the set time in this embodiment is not limited, and corresponding time, for example, 70s, 75s, etc., may be set according to actual needs; the time can be 20s, 30s, 35s and the like, and corresponding setting can be made according to actual needs.
In the embodiment, at least two self-locking switches 30 are arranged, and the opening mode of the self-locking switches 30 is specifically set, so as to prevent the deepwater operator from accidentally touching the self-locking switches, for example, on the land, the self-locking switches are inadvertently touched, which causes unnecessary troubles; in order to further prevent the deepwater operator from touching the self-locking switch 30 carelessly, and thus the beidou communication terminal 20 should not be turned on, the following steps can be set: at least one self-locking switch in the plurality of self-locking switches and the rest self-locking switches are not on the same surface of the shell. In this embodiment, at least one of the plurality of self-locking switches is located on the first outer surface 11 of the housing, and the remaining self-locking switches are located on an outer surface of the housing other than the first outer surface 11.
Referring to fig. 1 and 2, in the present embodiment, there are 5 self-locking switches, four of which are on the first outer surface 11 of the housing; the other self-locking switch 40 is on the housing except the first outer surface 11, and the self-locking switch 40 on the outer surface is a power switch, and the outer surface is perpendicular to the first outer surface 11. After the self-locking switch 40 is activated as a power switch, the battery 51 in the battery compartment 50 supplies power to the life saving equipment (refer to fig. 6). Because all the self-locking switches are not arranged on the same outer surface of the shell, deep water operators can touch the self-locking switches on the same outer surface at the same time, but the probability of touching the self-locking switches on all the outer surfaces at the same time is greatly reduced, and the safety and the reliability of the lifesaving equipment are further improved.
The self-locking switch is started in the set sequence as follows: the sequence of the sequential opening from the first self-locking switch to the last self-locking switch; or, the sequence of opening is disordered from the first self-locking switch to the last self-locking switch. In the embodiment, four self-locking switches on the same outer surface of the shell are annularly arranged; the self-locking switches 40 (i.e., power switches) located on the other outer surfaces of the housing are first pressed and then sprung, and the remaining four self-locking switches are pressed and then sprung in a set sequence.
In this embodiment, the four self-locking switches on the first outer surface 11 of the housing include a first self-locking switch 30a, a second self-locking switch 30b, a third self-locking switch 30c and a fourth self-locking switch 30d, which are sequentially arranged;
the four self-locking switches are pressed down and then bounced up according to the following sequence:
a first self-locking switch 30a, a second self-locking switch 30b, a third self-locking switch 30c and a fourth self-locking switch 30d (which are sequentially turned on); or, the first self-locking switch 30a, the third self-locking switch 30c, the second self-locking switch 30b and the fourth self-locking switch 30d are switched on in disorder; or, the first self-locking switch 30a, the fourth self-locking switch 30d, the second self-locking switch 30b, and the third self-locking switch 30c are switched on in disorder; or, the first self-locking switch 30a, the second self-locking switch 30b, the fourth self-locking switch 30d, and the third self-locking switch 30c are switched on in disorder; alternatively, the first self-locking switch 30a, the fourth self-locking switch 30d, the third self-locking switch 30c, and the second self-locking switch 30b are turned on in disorder.
It should be noted that, the turn-on sequence of the self-locking switch in this embodiment is not limited, and other setting sequences may also be used, which are not described in detail in this embodiment; and the number of the self-locking switches is not limited.
In addition, when deepwater operators wear the lifesaving equipment provided by the embodiment of the invention, the deepwater operators can directly send distress signals to a search and rescue center by operating the self-locking switch 30 when the deepwater operators are on water, and the lifesaving equipment is not only limited to be used in underwater operation; when the self-locking switch 30 is operated on water, the self-locking switch 30 is turned on in the same manner as the self-locking switch described in the above embodiment.
In this embodiment, the lifesaving device is used in the rescue at sea, and therefore, the sealing and the waterproof performance of the lifesaving device need to be considered.
