Description
Technical field
The present invention relates to rescue at sea field, more particularly to a kind of seashore outdoor bathing place ebb warning system.
Background technology
With the progress and growth in the living standard of material life, people generally select Scene Tourist and put in festivals or holidays
Loose body and mind, and personal safety is the problem that visitor most pays close attention in Scene Tourist, particularly with the visitor for going to coastal city to spend a holiday,
When seashore outdoor bathing place surfing is swum, most worrying because seawater ebb oneself will be involved in the sea, annual summer leads because of ebb
The event for causing visitor dead is appeared in the newspapers end repeatly, and so, visitor does not enjoy the enjoyment of tourism belt not only, to bear to travel on the contrary
The pain of injury that accident is brought, is all heavy strike to visitor and local tour administrative department.
Visitor's death this problem is brought in order to solve ebb, carrying the spend a holiday seashore outdoor bathing place of visitor of beach would generally arrange
Special experienced local employee carries out Real Time Observation to sea, and the ebb feelings that rise of seawater are judged by the experience of oneself
Condition, or buoy is set across the sea, personnel's Real Time Observation buoy position is arranged to judge the ebb situation that rises of seawater, these sides
Method can play the effect of ebb alarm to a certain extent, but often precision not enough, reflects more sluggish.Meanwhile, existing skill
Lack the testing mechanism to marine visitor in art, it is difficult to for the rescue of local tour administrative department provides strong data branch
Support.
Accordingly, it would be desirable to a kind of new seashore outdoor bathing place ebb warning system, can abandon existing by artificial experience or letter

Specific embodiment
The embodiment to seashore outdoor bathing place of the invention ebb warning system is described in detail below with reference to accompanying drawings.
Ebb is commonly referred to as the decline process from climax to sea in this period of low tide, is also called ebb tide.Ebb
It is to be caused by the gravitation between the moon and ground.When the moon and the nearest marine site of the earth be at the incoming tide, the earth back side
Marine site is ebb, and by taking bay as an example, during ebb, seawater flows to off-lying sea from bay, causes water level reduction, flood tide phase in bay
Between, seawater is flowed in bay from off-lying sea, causes water level in bay to raise.The earth circles for every 24 hours certainly, so seawater is daily
With regard to fluctuation twice, and the sun is only equivalent to the 5/11 of the moon to the influence power of tide.
For the visitor that outdoor bathing place by the sea is played, due to the limited time played on local seashore, even if seawater is moved back
The time of tidal bulge tide is relatively fixed, and also tends to be understood in time, and simply pays close attention to surfing swimming in itself, but, if
Still played in the sea when on the ebb, due to the huge thrust that seawater brings at ebb tide, can will have little time disembarkation easily
Visitor is involved in deep-sea, causes visitor to be drowned.Even if understanding the approximate time of local seawater ebb flood tide, but because seawater is moved back
Every day time of tidal bulge tide, all in fine setting, if careless, still suffers from being involved in possibility in the sea.
Ebb warning means of the prior art rely on artificial experience or light instrument mostly, and accuracy of detection is not high, and do not have
There is the identification technology of sea visitor's quantity, it is impossible to make and accurately, targetedly alarm tactful.
Ebb warning system in seashore outdoor bathing place of the invention, can exactly judge to work as by high-precision electron detection device
