The Qiantang river is located in Hangzhou city of Zhejiang province, is horn-shaped, is in the east sea when entering the sea, and is a Qiantang tide when entering the sea, and the tide water is easy to enter and is difficult to exit, so that people are famous all the year round and have a great deal of tourists to watch the special scenery. However, the speed of tidal water is extremely fast, the tidal water is just a white line before arrival, the time for people to respond is hardly given, surge tidal water is flung, when a large amount of tidal water enters from the mouth of a river in Qiantang, the river surface is rapidly reduced, so that the tidal water does not arrive at a uniform rise, and only the back waves push the front waves to be overlapped layer by layer, and the peak of the tide is up to 3-5 m.

Fifteen eighty months of the lunar calendar every year, the Qiantang river has the largest tidal bore, local people have customs for watching autumn tides from Han dynasty, a plurality of fixed tide watching points are arranged on two banks of the Qiantang river, so that people can conveniently watch spectacular tidal waters, but the scenes are too spectacular when the tidal waters come, the tidal waters are gradually clear from far to near, a tide watching person is easy to be addicted in watching the tidal waters and forgets to withdraw from the tide watching points in time, and the tide watching person is involved in the river waters every year. The warning equipment for the tide observation becomes an indispensable tide observation hard facility.

The existing tide rising warning devices which are not rarely applied to marine fishermen have weak warning effect and high manufacturing cost, do not form step strength on warning signals according to the distance, do not strengthen the signals of tide approaching, easily cause the signal receivers to psychologically form weakening of the signals after a long time, and easily cause personal safety accidents.
