Description
Technical field
The utility model belongs to technical field of automation, specifically is a kind of tidal bore velocity of propagation measurement mechanism based on step saltus step identification.
Background technology
In river tidal bore monitoring and forecasting and warning technology, whether needs contact tidewater according to checkout equipment, are divided into contact and detect and non-contact detection.Detect for contact, on the one hand because marine corrosion can cause the equipment loss, on the other hand, for the big tidal bore rivers as the Qiantang River, the impulsive force of its morning and evening tides makes very high for the installation requirement of equipment.So generally adopt non-contact detection at present, the existence limitation separately but prior art all remains unchanged on using.For example, for the river tidal surge detection method based on audio frequency characteristics identification, under the less situation of tidewater, audio frequency characteristics is obvious inadequately, can't reach the purpose of identification tidal bore.Then be unwell to night or river surface has situations such as mist based on the river tidal surge detection method of video identification.So river tidal surge detection method adaptability maximum based on flow velocity, but, since flow velocity and the whole flow velocity inconsistent (even just the opposite) of part during the tidal bore process, so detected flow velocity can not represent actual tidal bore velocity of propagation, the information that can't furnish a forecast and need.
Summary of the invention
The purpose of this utility model is in order to overcome the weak point of prior art, a kind of tidal bore velocity of propagation measurement mechanism based on step saltus step identification to be provided.
Technical solutions of the utility model are as follows:
A kind of tidal bore velocity of propagation measurement mechanism based on step saltus step identification is made up of the first radar wave current meter, the second radar wave current meter, first microprocessor, a GPRS module, second microprocessor, the 2nd GPRS module and server.
It is the two places of L with bank and distance that the first radar wave current meter and the second radar wave current meter are installed on the river course successively along the tidal bore working direction; The first radar wave current meter is connected with first microprocessor by serial ports, first microprocessor is connected with second microprocessor by a GPRS module, the second radar wave current meter is connected with second microprocessor by serial ports, and second microprocessor is connected with server by the 2nd GPRS module.
The beneficial effects of the utility model: adopt the radar wave current meter to carry out fluid-velocity survey, be not subjected to the influence of factors such as light, weather, can realize round-the-clock tidal bore measurement.Simultaneously, solved the problem that flow velocity that the radar wave current meter records can't replace the tidal bore velocity of propagation, the necessary information that realizes the tidal bore forecast is provided.
Description of drawings
Fig. 1 is structure drawing of device of the present utility model;
Flow speed data step saltus step figure when Fig. 2 arrives for tidal bore.
Embodiment
The utility model is described in further detail below in conjunction with accompanying drawing.
As shown in Figure 1, a kind of tidal bore velocity of propagation measurement mechanism based on step saltus step identification of the utility model is made up of the first radar wave current meter 1, the second radar wave current meter 2, first microprocessor 3, a GPRS module 4, second microprocessor 5, the 2nd GPRS module 6 and server 7.
It is the two places of L with bank and distance that the first radar wave current meter 1 and the second radar wave current meter 2 are installed on the river course successively along the tidal bore working direction.The first radar wave current meter 1 is connected with first microprocessor 3 by serial ports, first microprocessor 3 is connected with second microprocessor 5 by a GPRS module 4, the second radar wave current meter 2 is connected with second microprocessor 5 by serial ports, and second microprocessor 5 is connected with server 7 by the 2nd GPRS module 6.
Two radar wave current meters are gathered local flow speed data respectively, because flow speed data was the step saltus step when tidal bore arrived, as shown in Figure 2, first microprocessor 3 can be identified by the step saltus step of data that the first radar wave current meter 1 is gathered and obtain tidal bore and arrive the 1 on-site time of the first radar wave current meter
, second microprocessor 5 can be identified by the step saltus step of data that the second radar wave current meter 2 is gathered and obtain tidal bore and arrive the 2 on-site times of the second radar wave current meter
First microprocessor 3 passes through a GPRS module 4 with time data
Send second microprocessor 5 to.Second microprocessor 5 passes through time data
, time data
And two distance between the radar wave current meter
, calculate the tidal bore velocity of propagation
, and pass through the 2nd GPRS module 6 with the tidal bore velocity of propagation
And time data
Send the server 7 of far-end to, the time that arrives other place, river course for the forecast tidal bore submits necessary information.
More than by with reference in the accompanying drawings the expression exemplary embodiment the utility model has been done special displaying and explanation, to one skilled in the art, should be understood that, not deviating from various modifications and the change of making under thought of the present utility model and the scope in the form and details, all will be the infringement to the utility model patent.So real thought and scope that the utility model will be protected are limited by appending claims.
