Description
Technical field
The utility model relates to a kind of maritime search and rescue system, relates in particular to a kind of automatic dispensing device of search and rescue signal.
Background technology
When at sea taking place to fall into water accident, can search the wounded and missing crew in the shortest time is to reduce causality loss, saves the inevitable requirement of persons falling in water.Therefore, require personnel, promptly need to start fast search and rescue system, send distress signal in case fall into water.The automatic transmission of search and rescue signal becomes the first step that success is rescued.For the ease of rescue, search and rescue signal also must comprise drowning exact position.
Existing search and rescue signal dispensing device is the existence deficiency aspect automatic unlatching and the accurate position of falling into water of transmission.
Summary of the invention
Exist the search and rescue signal dispensing device to open automatically with the aspect of accurately determining to fall into water, position at prior art and have deficiency, the utility model provides a kind of fast automatic unlatching, can send the automatic dispensing device of the search and rescue signal of accurate positional information.
For achieving the above object, the utility model adopts following technical scheme:
The automatic dispensing device of search and rescue signal comprises successively emergency location information coding unit that the power supply, water-sensitive switch, emergency location information acquiring unit, the positional information of will crying for help that connect encode, the positional information transmitter unit that the positional information after will encoding is launched and the clock module that is used to be provided with the positional information emission duration.In case fall into water, the water-sensitive switch is opened rapidly, start the automatic dispensing device of search and rescue signal.The emergency location information acquiring unit is obtained and is got the emergency positional information and be transferred to emergency location information coding unit, encoded after, the positional information after the positional information transmitter unit will be encoded by default transmission frequency sends.
As preferably, be connected with integrated low-noise amplifier between described emergency location information acquiring unit and the emergency location information coding unit.Main effect is the location information signal that the emergency location information acquiring unit is obtained is eliminated noise and to amplify.
As preferably, described emergency location information acquiring unit is the gps signal receiving system.Can accurately obtain the emergency positional information.The emergency positional information comprises information such as the vessel number, title of longitude, latitude, the emergency of the position of crying for help.
As preferably, described positional information transmitter unit is a radiofrequency launcher.The radiofrequency launcher modulation is convenient, radiance is good and efficient is high.
As preferably, described power supply is the lithium battery of sustainable power supply.Lithium battery is in light weight, electric weight is sufficient.Also can be standby one in case the electric weight deficiency.
The automatic dispensing device of search and rescue signal of the present utility model can start automatically fast, sends accurate positional information, the efficient height, and validity is strong.
Description of drawings
Fig. 1 is the structural representation of embodiment.
Embodiment
Below in conjunction with Fig. 1 and embodiment the utility model is described further.
The automatic dispensing device of search and rescue signal as shown in Figure 1, comprises the power supply 1, water-sensitive switch 2, emergency location information acquiring unit 3, emergency location information coding unit 4, positional information transmitter unit 5 radiofrequency launchers and the clock module 6 that connect successively.Power supply 1 is the lithium battery of 3v, and emergency location information acquiring unit 3 is the gps signal receiving system, and positional information transmitter unit 5 is a radiofrequency launcher.
The automatic dispensing device of search and rescue signal is arranged on the life jacket, and usual water-sensitive switch 2 disconnects, and the automatic dispensing device of search and rescue signal is in not starting state.In case the accident of falling into water takes place, water inlet in the water-sensitive switch 2, conducting, start the automatic dispensing device of search and rescue signal fast, the gps signal receiving system begins once to obtain drowning positional information by predetermined per half a minute of frequency, and the drowning positional information that will obtain is sent to emergency location information coding unit 4, use the methods for forward error correction coding of high-gain to encode, positional information behind the coding is sent to radiofrequency launcher, and radiofrequency launcher was once outwards launched the emergency positional information in per 30 seconds according to predetermined frequency.
Being preferred embodiment of the present utility model only in sum, is not to be used for limiting practical range of the present utility model, and all equivalences of doing according to the content of the application's claim change and modify, and all should be technology category of the present utility model.
