Detailed Description
The invention is further described below with reference to examples. The following examples are presented only to aid in the understanding of the invention. It should be noted that it will be apparent to those skilled in the art that modifications can be made to the present invention without departing from the principles of the invention, and such modifications and adaptations are intended to be within the scope of the invention as defined in the following claims.
Example 1:
The invention provides a real-time monitoring system for flushing hydraulic foundation, which can record the whole echo data and perform power analysis so as to filter non-target reflection, and comprises the following steps: the system comprises an ultrasonic sensor, an acquisition instrument and a data processing system;
Wherein the ultrasonic sensor comprises an ultrasonic generating sensor and an ultrasonic receiving sensor; the acquisition instrument comprises an ultrasonic wave emission drive and an echo receiving instrument; the ultrasonic wave generating sensor is used for converting an electric signal generated by ultrasonic wave transmitting drive into ultrasonic vibration and transmitting the ultrasonic vibration to a specific direction, and the ultrasonic wave receiving sensor is used for generating an electric signal and transmitting the electric signal to the echo receiving instrument when receiving the echo; the data processing system is used for collecting, analyzing, storing and presenting echo data.
The ultrasonic wave generating and receiving sensor is commonly called a water depth transducer. The function one is to convert the electric signal wave into ultrasonic vibration and transmit the ultrasonic vibration in a specific direction (a certain transmitting angle exists), and the function two is to wait for the reflected wave, when the vibration wave (echo) with the same vibration frequency value as the frequency of the transducer arrives, the transducer resonates, and a larger current signal is generated and transmitted to the echo receiver. The application field of the water depth transducer is wide, such as radar, multi-beam and single-wave depth measuring instruments, various ultrasonic distance measuring instruments and the like.
The embodiment of the invention adopts a 300kHZ underwater acoustic transducer for development. The main design parameters are as follows:
center frequency: 300KHz + -5%;
Ranging range: 0.6 m-90 m;
Minimum impedance: 30 ohm + -20%;
capacitance: 7500 pF+ -20% @1kHz;
sensitivity: no-load drive voltage: 200Vpp, and the echo intensity is 10V when ranging is 0.7 m;
half power angle: @ -3dB:3.6 DEG + -10%, acute angle: 8.5 DEG + -10%.
In addition, according to the embodiment of the invention, the stm32F407 singlechip is used for ultrasonic driving and echo receiver development, so that the ultrasonic wave can be smoothly transplanted to a GD chip with the same model, and the working flow of the acquisition instrument is shown in figure 1.
Specifically, the hydraulic foundation flushing real-time monitoring system adopts an ultrasonic principle to detect the depth of the sea bottom, firstly, the system transmits a group of ultrasonic waves to the sea bottom, waits for the reflected wave of the sea bottom to reach the sensor surface, stops a timer after identifying the echo, and obtains the time t from the self-emission of the ultrasonic waves to the receiving of the echo. The product of the time t and the specific wave velocity of the ultrasonic wave in the region (wave velocity after comprehensive correction by water temperature, turbidity, salinity and the like) is the round trip distance of the sensor surface to the seabed, and the distance L from the sensor to the seabed is calculated. And (3) expanding the L value in a time domain to obtain the scouring or desilting value change of the seabed mud surface along with time. According to the size specification of the structure, 4, 6, 8 or 16 ultrasonic sensors are arranged along the external dimension to acquire the water depth data around the foundation, so that the flushing or the back silting of the foundation is described. The ultrasonic sensor (transducer) has a half power angle, the sensor is installed by depending on a foundation to be detected, the sensor is closer to the foundation, and the basic reflected wave is received back when the water depth is deeper. The reflected wave signals measured each time are stored in the industrial personal computer as original data, and depth data obtained after calculation are stored in the industrial personal computer and pushed to a remote server. The remote server presents the data of each monitoring site to the user in a visual manner.

And S5, the data processing system collects, analyzes, stores and presents the echo data.

S501, the data processing system receives echo data.
Specifically, the data of the acquisition instrument is output in a serial port 485 mode and is connected to the industrial personal computer, each sensor is a data sequence, and the serial number printed by the singlechip before the data starts is used as an identifier. After receiving the data, the data is stored into a database according to the identifier, and then an algorithm is introduced to analyze and process the echo signals.

And determining a reflection peak corresponding to bottom reflection according to the peak shape parameter k2, wherein for a mud surface in a discrete state, bottom emission is continuous, abrupt change is less, the reflection peak is reflected to a power peak and is a complete peak which is complete, steep in front and gentle in back, and reflection waves on a basic surface are generally emitted by irregular objects such as adsorbed oyster on the basic surface, and peak shapes are discontinuous and deformed.
Considering the characteristic of continuous monitoring, the change of the bottom surface is a tiny continuous change. When the system is installed, the program prints the tested echo pattern on a screen for adjusting the angle of the sensor, at the moment, the mud surface depth is manually judged, and the depth value is used as a known condition to be input into an algorithm. The depth value of each subsequent observation should be near the last observation.
When the three judging conditions are deviated, the data bar is marked with a label, and a warning is provided to remind people to judge.
S503, the data processing system stores the echo signals of each sensor in a database in a binary mode.
S504, receiving calculation result data pushed by the industrial personal computers and displaying the result data in form of tables and curves by the remote server.

Therefore, in the above graph, it can be determined that the depth of the bottom surface (without taking into account corrections of water temperature, turbidity, salinity, etc.) is 203×3.625= 735.875mm.
