As shown in fig. 1, fig. 2 and fig. 3, the utility model provides a flow velocity and flow rate monitoring system, including: a front-end measuring device 1, a communication device 2 and a background processing device 3; the front-end measuring device 1 is electrically connected with the communication device 2, and the communication device 2 is electrically connected with the background processing device 3; the front-end measuring device 1 is installed in a channel needing to monitor flow rate and flow rate, so that the flow rate and flow rate in a preset channel can be monitored in real time, the communication device 2 is used for collecting flow rate and flow rate data in the front-end measuring device 1 and then sending the flow rate and flow rate data to the background processing device 3, the background processing device 3 can display the flow rate and flow rate data and store the flow rate and flow rate data, and therefore a user can inquire the corresponding flow rate and flow rate data in real time through a mobile phone end or a computer end.
Further, the front-end monitoring device comprises a fixed platform 4 and an ultrasonic flowmeter for monitoring flow rate and flow rate in real time; the method comprises the following steps that a fixed platform 4 is installed in a preset channel, a case is arranged on the fixed platform 4, and then an ultrasonic flowmeter is installed in the case, so that the ultrasonic flowmeter can conduct fixed-point vertical flow velocity layered measurement; in addition, the installation of the ultrasonic flowmeter can be adaptively adjusted according to the environment, namely, the adaptive adjustment can be carried out according to factors such as the change of the terrain of a channel, the height of the water level of the channel, the difference of the climate around the channel and the like, so that the ultrasonic flowmeter is ensured to be positioned at the optimal measurement position, and the measurement quality is ensured.
Further, the ultrasonic flow meter comprises a device body and at least one transducer; the transducer is connected with the device body; a data processing module is arranged in the device body; the transducer is electrically connected with the data processing module; the data processing module is electrically connected with the communication device 2.
Specifically, the ultrasonic flowmeter in the present application uses a doppler ultrasonic flowmeter, and measures the doppler shift of a moving particle scattered sound wave in a fluid to obtain the velocity of the fluid, and combines a built-in pressure type water level gauge to measure the flow rate of the liquid by a velocity area method.
Wherein, be provided with four transducers in this application, every transducer is both transmitter and 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 4 (such as a river bottom or the fixed platform 4) 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 4 modes of fixed platform to install 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.
When the flow is calculated, the cross-section flow is calculated according to the flow velocity, the water level and the cross-sectional area data of the channel water area which are 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.

And if the acquisition board card fails to upload the data, the primary data transmission module is automatically reconnected. And if the response frame sent by the data transmission module contains the acquisition board card parameter uploading request, the acquisition board card responds and uploads the acquisition board card system parameter content. When the network is disconnected, the self-storage can store the record, and the record is uploaded again when the network is recovered; then, the data transmission module transmits the flow speed and flow data to the background processing device 3.
Further, the background processing device 3 may be a calculable device, which includes a data receiving module, a data displaying module and a data storing module; the data display module and the data storage module are both electrically connected with the data receiving module; the data receiving module is electrically connected with the communication device 2.
