Below in conjunction with specific embodiment concrete realization of the present invention is described in detail:
Embodiment one:
Fig. 1 shows the realization flow of preventing drowned alarm method that first embodiment of the invention provides, and details are as follows:
In step S101, obtain swimmer's breathing temperature and/or ambient temperature.
In embodiments of the present invention; Gather swimmer's breathing temperature through breathing temperature sensor; And/or this swimmer's ambient temperature of ambient temperature sensor acquisition, and export and should breathe temperature value and/or ambient temperature value, in the practical implementation process; This collection swimmer breathes aligning swimmer's the nose areas of the sensor of temperature, and the sensor of this collection swimmer ambient temperature is installed in position, the swimmer crown.
In step S102; Obtain swimmer's respiratory cycle according to this swimmer's breathing temperature; When the respiratory cycle of confirming this swimmer greater than the preset period duration; And/or confirm that this ambient temperature is the duration of first preset temperature when surpassing preset water temperature duration, generates alarm control signal.
Wherein, obtaining the step of swimmer's respiratory cycle according to this swimmer's breathing temperature is specially:
Obtain this swimmer once exhale with breathing process in maximum temperature value and minimum temperature value;
Obtain the time corresponding point of this maximum temperature value and minimum temperature value, the respiratory cycle of obtaining the swimmer according to this time point.
Wherein, This maximum temperature value and minimum temperature value are meant the crest value and the trough value of the breathing temperature the when swimmer swims; Can obtain the swimmer according to this crest value and trough value time corresponding point and accomplish and once exhale and the air-breathing needed time, also i.e. respiratory cycle of this swimmer.In embodiments of the present invention, can repeatedly obtain swimmer's respiratory cycle, carry out the average respiratory cycle that statistical average obtains the swimmer then.
If this respiratory cycle greater than the preset period duration, then generates alarm control signal, otherwise, the respiratory cycle of obtaining the swimmer again.In addition, this preset period duration is meant gathers the normal cycle of respiration of swimmer before swimming in advance, also is that the swimmer accomplishes once expiration and air-breathing needed time before swimming.
In embodiments of the present invention, when this ambient temperature is the duration of first preset temperature when surpassing preset water temperature duration, also can generate alarm control signal, the following embodiment of detailed process two is said.
In step S103, according to the drowned alerting signal of this alarm control signal output.
In the practical implementation process; Specifically can be according to the drowned alerting signal of this alarm control signal output for exporting this alarm control signal to motor earlier; Open by Electric Machine Control buoy case chamber door again, also can serve as reasons have signal processing function the buoy case according to this alarm control signal, open chamber door automatically; Thereby the buoy in the buoy case emerges under the buoyancy of water effect, makes buoy on the water surface, export drowned alerting signal.
Wherein, in the buoy audible-visual annunciator can be set, buoy can be through luminous, the warning of sounding, and the form that perhaps combines with sound through light is reported to the police, and drowned situation occurs to remind the ground monitoring personnel.
In embodiments of the present invention, through gathering swimmer's breathing temperature and ambient temperature, and this temperature is analyzed; Thereby judge whether this swimmer is drowned; Use dual drowned identification and remedied the false alarm of existing drowned alarm method existence and failed to report alert defective, and when drowned, can on the water surface, produce the drowned alerting signal of forms such as luminous or sound; Solve warning message and be difficult under water transfer to the difficult problem on the water surface, thereby improved the reliability of drowned alarm.
