Detailed Description
The invention is further illustrated by the following examples in connection with the accompanying drawings.
As shown in fig. 1, the present invention provides a flow velocity and flow rate monitoring method, which comprises the following steps:
and step 300, sending the flow speed and flow data to a background server for query.
Particularly, the hydrological information in a preset channel can be monitored in real time, calculated and processed, and then hydrological data are obtained; then, processing and analyzing the hydrological data to obtain corresponding flow velocity and flow data, and storing the flow velocity and flow data; meanwhile, the flow speed and flow data are uploaded to a cloud end for a user to inquire; therefore, the flow velocity and the flow rate in each channel can be inquired in real time by the staff on the ship, so that the staff on the ship can take corresponding measures in advance according to the water regime change, and the navigation safety of the ship is ensured; and the purpose of remote real-time monitoring is realized by a simple and economic monitoring and metering means, so that good social benefit and economic benefit are realized.
Further, as shown in fig. 2, the monitoring hydrographic information in a predetermined channel, and performing calculation processing on the hydrographic information to obtain corresponding hydrographic data includes:
102, receiving reflected sound waves correspondingly reflected by the particles;
103, obtaining acoustic Doppler frequency shift data corresponding to the particles according to the sound waves and the reflected sound waves;
and step 104, calculating to obtain the flow velocity corresponding to the channel water area according to the acoustic Doppler frequency shift data.
Specifically, the hydrological data includes water level, water temperature, flow rate and flow rate; the monitoring module in this application can adopt doppler ultrasonic flowmeter, through the doppler shift who surveys the motion particle scattering sound wave in the fluid, can obtain the velocity of fluid, combines built-in pressure type water level gauge, utilizes the velocity area method, can measure the flow of liquid.
Wherein, this application is provided with four transducers, and every transducer is both the transmitter and the receiver, and the sound wave of certain fixed frequency is launched to the transducer, then receives the sound wave that is reflected back by the particulate matter in the water. Assuming that the moving speed of the particles is the same as the water body flow velocity, when the moving direction of the particles faces the transducer, the echo frequency received by the transducer is higher than the transmitting frequency; when the particles are moving away from the transducer, the transducer receives a lower echo frequency than the transmit frequency. This change in frequency caused by the movement of the particles is known as acoustic doppler shift.
The formula is shown as follows, Fd is 2F (V/C)
Where Fd is the acoustic Doppler shift; f is the frequency of the transmitted wave; v is the moving speed of the particles along the direction of the sound beam and is the corresponding flow velocity of the channel water area; c is the propagation velocity of the sound wave in water.
In the prior art, the installation methods of the doppler ultrasonic flowmeter are divided into two types, one is to install the doppler ultrasonic flowmeter on a fixed platform (such as a river bottom or a fixed platform) to perform layered measurement of the flow velocity of a fixed point vertical line, and the other is to install the doppler ultrasonic flowmeter on a mobile platform (such as an investigation ship) to perform measurement of a navigation flow velocity profile. Adopt fixed platform mode installation in this application, the sound wave discovery of this application does not have the contained angle with the particulate matter promptly, and the moving speed of particulate matter along the acoustic beam direction is the velocity of flow promptly.
The energy converter of the Doppler ultrasonic flowmeter is arranged at the downstream of a straight section of a channel or a pipeline with a fixed section, the length of the straight section is preferably 15-20 times of the hydraulic radius (the longer the straight section is, the higher the measurement precision is), and no flow-through barriers (such as a water gate, a weir and the like) are required in the distance range, so that the uniform and stable flow state of water flow at the front end of the energy converter probe is ensured; wherein, when the Doppler ultrasonic flowmeter is installed, the transducer is required to be installed at the bottom of a channel or a pipeline. To the application occasion that has the siltation can be with equipment support lift, reserve partly siltation height, prevent that equipment siltation from leading to the measurement deviation.
When the cross-section flow velocity of a river is monitored in real time, hydrological information such as water temperature and water level needs to be collected at the same time. And has certain requirements on water quality and flow measurement cross section.
Such as: when the floating objects in the water are too much and the Doppler ultrasonic flowmeter is used, weeds or plastic bags and the like can cover the transducer to cause the transducer to fail, and the covering objects on the transducer need to be removed in time when the instrument works abnormally. When the conditions are allowed, a trash rack can be arranged at the upstream, but the distance between the trash rack and an instrument is not less than 5 times of the hydraulic radius, so that the situation that aquatic plants and the like accumulate in front of the trash rack to cause unstable flow state is avoided, and impurities in front of the trash rack need to be removed regularly.
When the water quality reaches the second-level drinking water, a place with bubbles (such as a drop or a place with a certain distance downstream of a gate) is selected for measurement. When the flow state instability at the bubble position does not accord with the flow measuring flow state requirement and the effective auxiliary steady flow measure (such as arranging a rectifier grid or a steady flow cover plate) can not be adopted, only the flow state steady section can be selected for measurement, and the following special measures are adopted:
(1) the upstream of the flow measuring section is required to be provided with a straight section with the width being 10 times of that of the channel, the downstream is provided with a straight section with the width being 5 times of that of the channel, and the shape of the section is regular and stable so as to ensure that the flow state of water flow at the installation position is uniform and stable.
(2) If the flow state of the installation position is poor or the straight section is short, one method is to arrange a flow straightener or a flow stabilizing cover plate at the upstream to stabilize the flow state, at the moment, attention should be paid to blocking the flow straightener to play an opposite role when the weeds in the water are excessive, and the solution is to timely remove the weeds when the weeds block the flow straightener or add a trash rack at the upstream.
In the process of testing the flow of the cross section, the area actually tested is a middle layer area of the cross section, and the area is called as an actual testing area; the doppler ultrasonic flow meters in the four edge regions of the upper and bottom layers of the left and right shores and the measured cross section cannot provide test data or effective test data, collectively referred to as non-measured regions.
Further, after the calculating the flow velocity corresponding to the channel water area according to the acoustic doppler shift data, the method further includes:
and 105, calculating to obtain the flow corresponding to the channel water area according to the flow velocity, the water level and the sectional area data of the channel water area.
Specifically, when calculating the flow rate, it is necessary to calculate the cross-sectional flow rate from the flow rate, the water level, and the cross-sectional area data of the channel water area collected in real time. When calculating the flow, corresponding data needs to be input according to a channel of a corresponding type, such as:
square pipeline: channel side length needs to be input.
Rectangular pipeline: the width and height of the channel needs to be input.
Trapezoidal pipeline: the length of the upper bottom edge, the length of the lower bottom edge and the height of the trapezoidal channel are required to be input.
Circular pipeline: the input diameter is required.
An elliptical pipeline: a long radius and a short radius need to be input.
River course: the total width of the river channel, the bottom width of the river channel, the center height of the river channel and the number of sensors need to be input. Therefore, according to the flow velocity obtained by the calculation, and the water level and the sectional area data of the channel water area, the flow corresponding to the channel water area can be obtained.
Further, the analyzing the hydrologic data to obtain and store corresponding flow velocity and flow data includes:
analyzing the hydrological data to obtain corresponding flow velocity and flow data and storing the flow velocity and flow data;
and displaying the flow speed and flow data.
Specifically, hydrologic data are acquired through a telemetering terminal, then the hydrologic data are analyzed and processed to obtain corresponding flow rate and flow data, and then the flow rate and flow data are sent to a background server to be stored.
Further, the sending the flow rate and flow data to a background server for querying includes:
sending the flow speed and flow data to a background server;
and the background server stores the flow speed and flow data for inquiry.
Specifically, the flow rate and flow data are sent to a background server, then the background server receives the flow rate and flow data, processes the flow rate and flow data into display data, and finally displays the display data in the background server for a client to inquire; the user can browse the data information of each site through a WEB or mobile browser.
The hydrological information in a preset channel can be monitored in real time, and is calculated and processed to obtain hydrological data; then, processing and analyzing the hydrological data to obtain corresponding flow velocity and flow data, and storing the flow velocity and flow data; meanwhile, the flow speed and flow data are uploaded to a cloud end for a user to inquire; therefore, the flow velocity and the flow rate in each channel can be inquired in real time by the staff on the ship, so that the staff on the ship can take corresponding measures in advance according to the water regime change, and the navigation safety of the ship is ensured; and the purpose of remote real-time monitoring is realized by a simple and economic monitoring and metering means, so that good social benefit and economic benefit are realized.
