[0020] Figure 1This is a diagram of the transmission equipment architecture according to an embodiment of the utility model. Figure 2 Schematic diagram of a control box according to an embodiment of the utility model.

[0021] like Figure 1 As shown, the transmission device includes a fluid measurement module 11, a control module 12, a connection module 13 coupled between the fluid measurement module 11 and the control module 12, and a power supply module 14 for supplying power.

[0022] Specifically, the fluid measurement module 11 is fixed on a base fixing plate (not shown). When the fluid measurement module 11 is arranged at the bottom of the fluid (for example, the bottom of a river), the base fixing plate enables the detection surface of the fluid measurement module 11 to be in the fluid to measure the fluid.

[0023] The control module 12 and the fluid measurement module 11 are connected in communication through the connection module 13. The control module 12 periodically reads the measurement data of the fluid measurement module 13 at a first time interval, and periodically sends the fluid analysis results generated based on the measurement data to the preset device at a second time interval. The connection module 13 is coupled between the fluid measurement module 11 and the control module 12 to provide a communication channel between the measurement module 11 and the control module 12. It can be understood that the communication channel provided by the connection module 13 can be a wireless channel or a wired channel. Considering the measurement environment of the fluid, when the communication channel is a wired channel, the connection module 13 may include a cable portion 131 and a plurality of load-bearing blocks 132, wherein the plurality of load-bearing blocks 132 are distributed on the cable portion 131 to fix the cable portion 131 so that the cable portion 131 will not be damaged or disconnected from the measurement module 11 or the control module 12 due to the flow of fluid.

[0024] In one embodiment, the cable part 131 includes a cable and a soft rope, wherein the cable is used for data transmission and / or power supply, and the soft rope is intertwined with the cable to reduce the tension on the cable, thereby improving the reliability of the cable part. The load-bearing block 132 can be a cube formed by concrete pouring or metal or other dense materials. In actual application, the number of load-bearing blocks 132 can be appropriately increased according to the width of the river channel to ensure that they are tied to the soft rope, fixed in sections, and the cable is sunk to the bottom of the water. The size of the load-bearing block 132 can be 30 cm long, 20 cm wide, and 10 cm high. The number of load-bearing blocks 132 can be appropriately increased according to the width of the river channel to ensure that they are tied to the soft rope to sink the cable laid in the water body to the bottom of the water.

[0025] In one embodiment, the fluid measurement module 11 includes a Doppler velocity and direction profiler, such as the Nortek Signature series. When measuring, a fixed-point mode is used, and the detection surface (i.e., the probe) faces upward. When applied in a river channel, it is often necessary to fix the fluid measurement module 11 to the riverbed. Since there is often silt on the riverbed, in order to prevent the fluid measurement module 11 from sinking into the silt and causing the detection surface to be covered with silt, a base fixing plate can be used to fix and support the fluid measurement module 11. The base fixing plate can be made of stainless steel, for example, it can be made into a hollow stainless steel vertical body with a height of 20-30 cm. At the top of the vertical body, a fixing member (e.g., bolts, fixing holes, buckles, etc.) is provided to achieve a fixed connection with the fluid measurement module 11.

[0026] The control box includes a box-shaped housing 15 for accommodating the control module 12 and the power module 14 so as to reduce the impact of the external environment on the above two modules.

[0027] like Figure 2 As shown, the power module 14 includes a photovoltaic component 141 and a battery 142, wherein the photovoltaic component includes a photovoltaic panel 1411 and a converter 1412, wherein the photovoltaic panel 1411 is arranged on the box-shaped housing 15 to obtain solar energy; the converter 1412 is coupled between the photovoltaic panel and the battery 142 to convert the obtained solar energy into electrical energy and provide the electrical energy to the battery 142. The control module 12 includes a workstation 121 and a routing device 122, wherein the routing device 122 is a wireless routing device configured to transmit fluid analysis results wirelessly, for example, the monitoring information can be sent to the user by email at regular intervals. The workstation 121 is powered by the battery 142, and the data transmission interface of the workstation 121 is connected to the cable, and the data collection process is controlled by the built-in fixed-point data collection software.

[0028] Although Figure 2 The connection relationship between the modules is not shown, but those skilled in the art will appreciate that the connection mode and placement of the modules can be adjusted according to the requirements of the application scenario. For example, the converter 1412 can also be arranged outside the box-shaped housing 15.

[0029] In one embodiment, the workstation 121 is provided with an automatic flow data processing and transmission application program, which can read the collected fixed-point data at regular intervals, obtain the data collection time, water pressure value and stratified flow velocity and direction data, and determine the vertical average flow velocity and direction through an algorithm, and then determine the cross-sectional flow through the relationship between the calibrated vertical average flow velocity, water level and cross-sectional flow, and regularly send the processed fluid analysis results to the user. It can be understood that the fluid analysis results here can not only be the results generated based on the above data, but also include at least one of the above data. When the application starts to execute data collection, it will start the water level and flow data automatic processing and transmission program, and periodically read the data at a first time interval, for example, "statistics every 5 minutes", display the processing results on the user interface, and save them.

[0030] In order to calculate the cross-sectional flow more accurately, the fluid can be measured multiple times to obtain the cross-sectional flow. The relationship between the vertical average flow velocity and the cross-sectional flow is obtained by calibrating with the vertical average flow velocity measured by the bottom-mounted water level and flow data online transmission system, and the relevant parameters are written in the application. Then, the monitoring results can be sent to the designated users by pressing "Statistics every 5 minutes" and "Flow statistics every 4 hours" (i.e., the second time interval) in turn.

[0031] Figure 3 It is a schematic diagram of the connection between a workstation and a user according to an embodiment of the utility model.

[0032] The user interface of the workstation 121 is used to provide an input and output interface to the user. Figure 3 As shown, the user interface includes a component control area (left side) and a work information display area, wherein the operator can select a specific control in the control area to enable the workstation 121 to perform a corresponding function. For example, after clicking the control "Open", the specified file can be opened; clicking the control "Statistics every 5 minutes" or "Traffic statistics every 4 hours" can trigger the corresponding function. Custom controls provide users with flexible configuration conditions.

[0033] When the user observes various parameters or reminder information on the user interface, the user interface can be used to control the data collection or calculation process.

[0034] The workstation 121 is connected to the remote computer 20 through the routing device 122, so that the analysis results, operating status and other parameters can be periodically sent to the remote computer 20. Similarly, the remote computer 20 can also feedback relevant requirements to the workstation 121, so that the workstation 121 adjusts the subsequent operation of the fluid measurement module 11 according to the requirements.

[0035] The bottom-mounted water level and flow data online transmission system provided by the utility model has a simple system composition, low cost, and is easy to promote. It is generally applicable to the online monitoring of water level and flow of river sections, and can automatically process and transmit self-edited water level and flow data.

[0036] The description of the above embodiments is to facilitate the understanding and use of the present invention by those skilled in the art. It is obvious that those familiar with the art can easily make various modifications to these embodiments and apply the general principles described herein to other embodiments without creative work. Therefore, the present invention is not limited to the above embodiments, and improvements and modifications made by those skilled in the art based on the disclosure of the present invention without departing from the scope of the present invention should be within the scope of protection of the present invention.
