[0024] The present invention will be further explained and described below with reference to the accompanying drawings and specific embodiments.

[0025] ADCP stands for Acoustic Doppler Current Profiler.

[0026] Reference Figure 1 and Figure 2 This application provides an ADCP automatic current measurement device based on a cableway, including a lead weight F, a cableway system, and a communication architecture (not shown).

[0027] Reference Figure 1In this embodiment, the lead fish F is equipped with an ADCP, which includes a signal transceiver module, a processing module, and a communication module. The processing module connects the signal transceiver module and the communication module, and is used to process the signals received by the signal transceiver module to obtain measurement results. It should be noted that the processing module's processing of the signals received by the signal transceiver module is based on existing data processing technology. Using existing processing methods, measurement results including top, solid, bottom, left, and right bank flow rates, straight-line distances, water depths, and total areas can be obtained. This embodiment does not improve the processing method.

[0028] Reference Figure 1 and Figure 2 In this embodiment of the application, the signal transceiver module includes an FPGA module and a transducer module, and the transducer module is connected to the FPGA module and the DSP module; the transducer module includes a transducer (transceiver combined transducer), an adapter board, a transmitting circuit board and a receiving circuit board, the adapter board is connected to the transducer, the adapter board and the transmitting circuit board, the transmitting circuit board is connected to the FPGA module and the receiving circuit board is connected to the DSP module.

[0029] Optionally, the ADCP can be arranged in the form of various circuit boards, and may also include a power board and a digital circuit board. The power board is used to supply 10-36V power to other circuit boards. The FPGA module and DSP module are set on the digital circuit board. The FPGA control module is used for transmitting signals, receiving signals, signal gain compensation and sensor data acquisition. The transducer realizes the conversion of electrical energy into acoustic energy. The adapter board is used to transfer the transmitted signal and the received signal.

[0030] Optionally, the processing module includes a DSP module, including but not limited to TMS320C6713BPYP200 and HESG324442R112 / F; the communication module includes a RS232 chip and a RS485 chip, with RS232 and RS485 communication modes. Other embodiments may include either a RS232 chip or a RS485 chip, without specific limitation; the FPGA module includes but is not limited to Xilinx series or Intel series.

[0031] Reference Figure 1 In this embodiment of the application, the cableway system includes a cableway control module L, a cableway module, and a motion module; the motion module connects the cableway module, the lead weight, and the cableway control module, and the cableway control module is used to control the motion module and communicate with the communication module to receive measurement results.

[0032] Reference Figure 1Optionally, the cableway control module is a terminal with a display screen (e.g., a PC controller) that can receive and directly display measurement results, allowing relevant personnel to directly and promptly understand the measurement results. Through the ADCP processing module and communication module, the function of real-time flow calculation is realized. It does not require parsing and post-processing through host computer software. The calculation results can be displayed on the terminal of the cableway control module online and can be transmitted to the hydrological bureau system in real time through the communication module and communication architecture.

[0033] Reference Figure 1 In this embodiment of the application, the cableway module includes a support 1 and a cableway 2. The support 1 is divided into two parts located on both banks of the river, and the cableway 2 is installed on the support 1.

[0034] Reference Figure 1 In this embodiment, the motion module includes a gondola 3 (with a built-in motor) and a circulation cable 4. The gondola 3 is slidably mounted on the cableway 2 and is equipped with pulleys. The circulation cable 4 is connected to the pulleys. The cableway control module is used to control the gondola 3 to move horizontally in the X direction and to control the pulleys to make the circulation cable 4 move vertically in the Y direction. This ensures that the ADCP remains fixed at the water depth, with an upward and downward fluctuation error of less than ±2cm. This allows for adjustment of the horizontal position and depth, enabling the ADCP to be measured at different horizontal positions and depths, satisfying both the requirements of vertical measurement and the requirements of navigation measurement.

[0035] In this embodiment, the communication architecture includes a server (e.g., a Modbus server), a switch, and a wireless bridge. The server connects to the communication module (e.g., via RS485) and communicates with the switch. Measurement results are transmitted in a transparent transmission mode. For example, measurement results are uploaded in data packets based on Modbus. The maximum Modbus RTU frame is 256 bytes, which may include: 2 bytes of fixed information + register data (up to 252 bytes) + 2 bytes of checksum. The fixed information includes the ADCP device number (child node address, 1 byte) + function code (1 byte). The register data includes ADCP device information, measurement time, configuration parameters, and measurement results. Specifically, the server connects to the wireless bridge via a network cable, and the wireless bridge connects to the switch via a network cable, thus enabling communication between the server and the switch. Finally, the switch connects to the cableway control module via a network cable, ultimately enabling communication between the processing module and the cableway control module, allowing the measurement results from the processing module to be transmitted to the cableway control module. It should be noted that the measurement results can be transmitted to the hydrological bureau system via the server or the cableway control module.

[0036] Optionally, during the actual measurement, relevant personnel can input the corresponding parameters, such as the distance between the left and right banks, depth, and number of repeated measurements, into the interface of the cableway control module. Then, the cableway control module automatically controls the cableway module and motion module to perform automatic measurements based on the input parameters, so that the ADCP calculates and outputs the measurement results in real time. The cableway control module can output corresponding reports based on the received measurement results.

[0037] The ADCP automatic flow measurement device based on the cableway, as described in this application embodiment, allows the cableway control module to automatically control the cableway module and motion module after parameter configuration. This eliminates the need for manual operation of the cableway and motion modules and enables automatic issuance of measurement commands for fully automated measurement. These commands are also transmitted via a communication architecture. Furthermore, the ADCP measurement range covers the entire cross-section, allowing for precise control of the distance between the left and right banks from shallow to deep water. The ADCP features real-time flow calculation and supports the export of customized measurement results, covering specified elements and indicators. Additionally, the Modbus transparently transmits measurement results, allowing switching between the communication modes of the ADCP and Modbus server when executing corresponding modes, such as automatic control or transmission. Measurement results do not require parsing and post-processing by host computer software; they are calculated online, displayed on the cableway control module, and transmitted to the hydrological bureau system in real time.

[0038] The above is a detailed description of the preferred embodiments of the present utility model. However, the present utility model is not limited to the embodiments. Those skilled in the art can make various equivalent modifications or substitutions without departing from the spirit of the present utility model. All such equivalent modifications or substitutions are included within the scope defined by the claims of this application.
