Description
Technical field
The present invention relates to a kind of warning device, particularly relate to a kind of private pool alarm.
Background technology
Along with the raising of people's living standard, many families begin to have private swimming pool.Yet private swimming pool many times and unlike the lido is having the special messenger to keep an eye on, if the pet of children or family is fallen into accidentally in the swimming pool and does not in time find or rescue, drowned dead accident will take place, therefore, private swimming pool normally use and monitoring becomes a very important safety problem.Some developed countries all put into effect corresponding legal requiremnt swimming pool configuration safety equipment, in case have the people particularly children fall into swimming pool accidentally and just can report to the police at once, greatly reduce the incidence that the mishap of drowned death takes place because fall into water accidentally.
The basic demand of existing swimming pool alarm is: the people that can detect constant weight under usual conditions fall into water (normally more than or equal to 6 kilograms human body weight), then alarm can send the alarm song of 100-115DB, thereby reminds people is made the lifesaving action of timely necessity, can save drowning people's life to greatest extent.
The principle of work of present existing pool alarm all is that the air pressure that the sound that produces in the wave that produces according to pool water surface or the water or wave produce judges whether the man overboard and sends chimes of doom basically.But, also there are other factors can produce wave, sound and air pressure in the swimming pool even sometimes the no one falls into, can produce certain wave and sound when in water, working such as the swimming pool cleaning machine, wind also can make the water surface produce wave, also have other objects to fall in the water and also can produce sound and wave such as stone, branch etc.,, particularly brought inconvenience during in night's rest as the user for the user as long as thereby alarm detects wave and sound and will sound the alarm and produce many wrong reports under these situations.
In addition, existing various pool alarm, great majority only adopt a kind of sensor to come the ANOMALOUS VARIATIONS situation of the sensing water surface, the alarm of this employing single-sensor can only detect ripples size, variation in water pressure or sound, can't distinguish with regard to human body and such live body and the non-living bodies such as stone, trees and swimming pool cleaning machine of animal, when falling into swimming pool such as trees, detected ripples signal may or coincide with the signal similar of human body entry, and alarm will produce wrong judgement and send chimes of doom this moment.
Therefore, in order to reduce wrong report, improve the accuracy of reporting to the police, many pool alarms have adopted the mode of two kinds of different sensor combinations, disclose a pool alarm that adopts two sensors as the patent No. for the GB2376553B BrP, a sensor is used for analyzing water surface wave to be changed, another sensor is used for analyzing the air pressure variations that wave produces, by two sensors analyze jointly ripples by wind-induced still be to fall into water by the people to cause, whether decision reports to the police then.Though this patent can make that the detection of signal is more accurate, still the drowning action of interference that can't well non-living bodies such as high wind, swimming pool cleaning machine be produced and human body, animal makes a distinction, and still various wrong reports in various degree can take place often.
