The structure that more than is the utility model sea level fluctuations real-time detection apparatus is formed, and explanation detects the principle and the flow process of sea level fluctuations based on the sea level fluctuations real-time detection apparatus of the utility model below.

Please combine with reference to figure 2 and Fig. 3, wherein Fig. 2 is that the utility model sea level fluctuations real-time detection apparatus detects the principle process synoptic diagram, and is as shown in the figure, and the flow process that the sea level fluctuations real-time detection apparatus through the utility model detects sea level fluctuations comprises the steps:

Step 1 at first, is provided with above-mentioned the utility model sea level fluctuations real-time detection apparatus on preparation of construction 10, the composition of pick-up unit is provided with according to the described structure of the foregoing description fully, and notes following data: the height h1 of crawler belt 101; The vertical range h2 of distance detector 2 and preparation of construction parts 102; The vertical range h3 of pressure detector 3 and preparation of construction parts 102; The spacing h4 of crawler belt 101 and preparation of construction parts 102.Wherein, if distance detector 2 employings is ultrasonic sensor, the vertical range that then should guarantee pressure detector 3 and ultrasonic sensor is more than or equal to ultrasonic sensor blind area scope maximal value.In the present embodiment, distance detector 2 is a ultrasonic sensor, and pressure detector 3 is a pressure transducer, and ultrasonic sensor is positioned at the pressure transducer top, and the vertical range of the two is more than or equal to 400mm.

Step 2; Carry out data acquisition through 4 pairs of pressure detectors of data acquisition system (DAS) 3; Judge whether seawater does not have excess pressure detecting device 3; If pressure detector 3 does not have measurement data or measurement data very little (equaling pressure detector 3 normality initial values), explain that then seawater does not have excess pressure detecting device 3, pressure detector 3 is not produced pressure action; If pressure detector 3 has measurement data (greater than pressure detector 3 normality initial values); Explain that then seawater has not had excess pressure detecting device 3; This moment, the measurement data with pressure detector 3 was as the criterion, with the measurement data acquisition arrangement of pressure detector 3, through data processing; Obtain the vertical range h31 of the real-time pressure detector 3 and the water surface; Described data processing calculates according to the relation of liquid pressure principle, the degree of depth and pressure pressure promptly to draw the distance that the water surface does not have excess pressure detecting device 3 that the operation of this data processing is accomplished by data acquisition system (DAS) 4.

Step 3 when pressure detector 3 does not have measurement data or measurement data very little, judges that seawater does not have excess pressure detecting device 3 by above-mentioned; Carry out data acquisition by data acquisition system (DAS) 4 detecting device 2 of adjusting the distance this moment; That is to say that measured by distance detector 2 this moment, is as the criterion with its measurement data; Measure the vertical range h21 of the real-time distance detector 2 and the water surface through distance detector 2; Gather and arrangement by data acquisition system (DAS) 4, because distance detector 2 measured numerical value directly are length, so it need not to pass through data processing operation again.

Step 4, data acquisition system (DAS) 4 is collected the measurement data of above-mentioned distance detector 2 and pressure detector 3 and arrangement, carries out the step that sea level fluctuations calculates.As shown in Figure 3, establishing sea level fluctuations is H, just the distance on seawater plan range ground.When the water surface does not have excess pressure detecting device 3, be as the criterion with the measured value of pressure detector 3 and calculate sea level fluctuations H, for:

H＝h1+h4-h3+h31

When the water surface does not have excess pressure detecting device 3, be as the criterion with the measured value of distance detector 2 and calculate sea level fluctuations H, for:

H＝h1+h4-h2-h21

Thereby draw desired measurement result, realize the real-time measurement of sea level fluctuations.Simultaneously; Owing to used intelligentized distance detector 2 and pressure detector 3, replaced the traditional contact type measurement mark post and the estimation metering system of throw-in type sensor, so; When preparation of construction 10 moves in seawater; Still can record measurement data, and calculate sea level fluctuations, realize the measurement of dynamic sea level fluctuations in real time according to above-mentioned principle.

Certainly; When distance detector 2 and pressure detector 3 are selected for use to ultrasonic sensor and pressure transducer; The signal that data acquisition system (DAS) 4 is collected in above-mentioned steps two and step 3 receives the influence of seawater fluctuation and extraneous other factors; So data acquisition system (DAS) 4 need be carried out conventional Filtering Processing to the measuring-signal that collects in step 2 and step 3, for example can adopt the filtering method of repeatedly totally averaging, and measuring-signal is tended to be steady; Acquired signal is carried out Filtering Processing for relatively more conventional technology, so no longer specify.

In addition; If pressure detector 3 adopts pressure sensors; Then before step 2 working pressure sensor measurement seawater pressure; Need carry out the operation steps that initial position message is demarcated to pressure transducer, translational speed and other related datas that can influence the pressure transducer measurement result of the density of sea water of concrete work place, fluctuation wind-force, preparation of construction is initialised in pressure transducer and the data acquisition system (DAS) 4, measure numerical value accurately so that can corresponding concrete working environment record.Initial position message demarcation about pressure transducer can be adopted conventional method, repeats no more at this.

The above is merely the schematic embodiment of the utility model, is not in order to limit the scope of the utility model.Any those skilled in the art, equivalent variations and the modification under the prerequisite of design that does not break away from the utility model and principle, made all should belong to the scope that the utility model is protected.
