Description

TECHNICAL FIELD

[0001] The application relates to the technical field of hydrological monitoring, and in particular to an ADCP cableway system capable of being remotely controlled at multiple ends. BACKGROUND

[0002] ADCP (acoustic Doppler current profiler) is a main device currently applied to river flow velocity and flow measurement. Due to the influence of the "residual vibration effect", the ADCP can form a blind area (cannot provide effective measurement data) near the transducer, which affects the ADCP measurement work. When the ADCP measures a river channel, the water flow near the river bank is relatively slow, and the water depth is relatively shallow, so the overall river hydrological condition is not very important, therefore, the ADCP measurement state is adjusted to focus on measuring the hydrological information of the central water area.

The method comprises the following steps: obtaining cross-section average flow velocity and H-ADCP index flow velocity data samples through a flow velocity ratio measurement device and an H-ADCP online monitor, judging the water level fluctuation characteristics of the flow measurement cross-section according to historical water level monitoring data of the river cross-section, constructing a self-correction model according to the river cross-section with large water level fluctuation amplitude, dividing the monitoring cross-section with small water level fluctuation into a high flow velocity sample set and a low flow velocity sample set, and constructing corresponding self-correction models according to the high flow velocity sample set and the low flow velocity sample set, and performing precision evaluation and testing on the self-correction models. The application improves the accuracy of the measured values of the H-ADCP by performing self-correction calculation on the measured data and the historical data.

[0004] Chinese patent application publication No. CN214793956U discloses an ADCP launching device, and the application relates to the field of hydrological monitoring, and specifically relates to an ADCP launching device. The ADCP launching device comprises an ADCP device and a main support. The support comprises a rotary column and a cross rod connected to the top end of the rotary column. A second fixed pulley is arranged at the connecting angle between the rotary column and the cross rod. A fixing plate is arranged on the column. A first take-up reel is arranged on the rotary column. A first fixed pulley is arranged at the overhead end of the cross rod. A take-up and release rope is arranged on the first take-up reel.

The other end of the traction rope is connected to a river bank guide rope through a buckle clamp. The ADCP launching device is simple and convenient to use, and has low requirements on personnel operation.

[0005] However, the above method has the following problems: the effective test range of the device is not considered, the collected data is not pre-screened, and the ADCP device cannot be adjusted in time according to the hydrological changes. SUMMARY

[0006] Therefore, the application provides a multi-terminal remote control ADCP cableway system to overcome the problems in the prior art that the effective test range of the device is not considered, the collected data is not pre-screened, and the ADCP device cannot be adjusted in time according to the hydrological changes.

[0007] To achieve the above-mentioned purpose, the application provides a multi-terminal remote control ADCP cableway system, comprising:

[0008] a cableway traveler for moving the ADCP detector on a detection section and capable of adjusting the height of the ADCP detector;

[0009] the ADCP detector connected with the cableway traveler for detecting the flow parameters;

[0010] a controller connected with the cableway traveler and the ADCP detector respectively for acquiring the flow parameters and analyzing and judging the running state of the ADCP detector according to the flow parameters, and driving the cableway traveler to move the position of the ADCP detector according to the analysis result;

[0011] wherein the detection section is the cross section of the flow for parameter test, and the flow parameters include height value, water level value, flow speed value and width value.

[0012] Further, the ADCP detector comprises:

[0013] a height unit connected with the controller for measuring the height of the ADCP detector from the water surface and the depth of the flow;

[0014] a speed measuring unit connected with the cableway traveler and the controller respectively for measuring the flow speed of the flow;

[0015] a distance measuring unit connected with the cableway traveler and the controller respectively for measuring the width of the flow;

[0016] an alarm unit connected with the controller for issuing sound and light alarm.

[0017] Further, the controller acquires the height value measured by the height unit and compares the height value with a preset height value;

[0018] if the height value is less than the preset height value, the controller drives the cableway traveler to lift the ADCP detector to the preset height value.

[0019] wherein the height value is the height of the ADCP detector from the water surface; and the height preset value is negatively correlated with the frequency of the acoustic wave of the ADCP detector.

[0020] Further, the controller obtains a flow rate value measured by the flow rate measuring unit and compares the flow rate value with a flow rate set value;

[0021] If the flow rate value is less than the flow rate set value, the controller determines that the measurement point is located in the edge water area.

[0022] If the flow rate value is not less than the flow rate set value, the controller determines that the measurement point is located in the center water area.

[0023] wherein the flow rate value is the flow rate of the water flow; and the flow rate set value is positively correlated with the average value of the past flow rate.

[0024] Further, the controller obtains a water level value of the center water area measured by the height measuring unit and compares the water level value with a first water level preset value and a second water level preset value;

[0025] If the water level value is less than the first water level preset value, the controller determines that the water flow of the measurement point is reduced, and the alarm unit issues an audible and light alarm.

[0026] If the water level value is not less than the first water level preset value and less than the second water level preset value, the controller determines that the water flow of the measurement point is normal.

[0027] If the water level value is not less than the second water level preset value, the controller determines that the water flow of the measurement point is increased, and the alarm unit issues an audible and light alarm.

[0028] wherein the water level value is the depth of the water flow; and the first water level preset value and the second water level preset value are positively correlated with the average value of the past water level.

[0029] Further, in the state that the controller determines that the water flow of the measurement point is increased, the distance measuring unit measures a width value of the water flow, the controller obtains the width value and compares the width value with a width preset value;

[0030] If the width value is less than the width preset value, the controller determines that the width of the water flow is normal.

[0031] If the width value is not less than the width preset value, the controller determines that the width of the water flow is too wide, and the alarm unit issues an audible and light alarm.

[0032] wherein the width preset value is positively correlated with the average value of the past width.

[0033] Further, when the controller determines that the measuring point is located in the edge water area state, the cableway traveler drives the ADCP detector at a normal speed.

[0034] Further, when the controller determines that the measuring point is located in the center water area state, the cableway traveler drives the ADCP detector at a working speed.

[0035] Wherein, the working speed is less than the normal speed.

[0036] Further, when the height unit detects that the height value is in a periodic change state, the controller draws a curve diagram of the measured height value, and calculates an amplitude of the height value according to the curve diagram and compares the amplitude with an amplitude preset value.

[0037] If the amplitude is less than the amplitude preset value, the controller determines that the ADCP detector moves stably.

[0038] If the amplitude is not less than the amplitude preset value, the controller determines that the ADCP detector moves unstably, and the cableway traveler reduces the moving speed of the ADCP detector.

[0039] Wherein, the amplitude preset value is positively correlated with the cableway length.

[0040] Further, when the controller determines that the ADCP detector moves stably, the controller calculates a mean value of the height value according to the curve diagram.

[0041] Compared with the prior art, the system of the present application effectively obtains the hydrological parameters of the water flow by setting the above-mentioned devices, thereby guiding the adjustment of the detection position and the operation state of the ADCP detector, improving the working efficiency of the ADCP detector, and effectively improving the stability and practicability of the ADCP detector.

[0042] Further, by obtaining the height of the ADCP detector from the water surface, the working position of the ADCP detector is effectively obtained, and the blind area of the ADCP detector is avoided according to the height of the ADCP detector from the water surface, thereby further improving the stability and practicability of the ADCP detector.

[0043] Further, by using the hydrological parameters obtained by the ADCP detector, the various hydrological parameters of the water flow are effectively monitored, and the effective data is filtered and screened, thereby improving the detection accuracy and further improving the stability and practicability of the ADCP detector.

[0044] Further, the working state of the ADCP detector can be obtained more accurately by using the curve and data combination analysis, the hydrological data detection accuracy is effectively improved, and the stability and practicality of the ADCP detector are further improved.

[0064] Specifically, the system of the present application utilizes the above-mentioned device setting mode, effectively obtains the hydrological parameters of the flow, thereby guiding the adjustment of the detection position and the running state of the ADCP detector, improves the working efficiency of the ADCP detector, and effectively improves the stability and practicality of the ADCP detector.

[0065] Specifically, the controller acquires the height value measured by the height unit and compares the height value with a height preset value;

[0066] If the height value is less than the height preset value, the controller drives the cable traveler to lift the ADCP detector to the height preset value;

[0067] Referring to Figure 3 Fig. 1 shows a structure diagram of the ADCP detector height adjustment according to an embodiment of the present application, wherein the cable traveler 1 comprises a cable 11 and a lifter 12, and the cable 11 is arranged above the river channel; the lifter 12 is connected with the cable 11.

[0070] Wherein, the height value is the height of the ADCP detector from the water surface; and the height preset value is negatively correlated with the acoustic frequency of the ADCP detector.

[0071] In one embodiment, when the acoustic frequency of the ADCP detector is 1000 Hz, the height preset value is 2 meters;

[0072] When the acoustic frequency of the ADCP detector is 2000 Hz, the height preset value is 1.5 meters;

[0073] When the acoustic frequency of the ADCP detector is 3000 Hz, the height preset value is 1 meter.

[0074] Specifically, by acquiring the height of the ADCP detector from the water surface, the working position of the ADCP detector is effectively acquired, and the blind area of the ADCP detector detection is avoided according to the height of the ADCP detector from the water surface, thereby further improving the stability and practicability of the ADCP detector.

[0075] Specifically, the controller acquires the flow rate value measured by the velocity measurement unit and compares the flow rate value with a flow rate set value;

[0076] If the flow rate value is less than the flow rate set value, the controller determines that the measurement point is located in the edge water area;

[0077] If the flow rate value is not less than the flow rate setting value, the controller determines that the measurement point is located in the central water area;

[0078] Embodiment 2: Please continue to refer to Figure 3 As shown in the figure, on the basis of embodiment 1, the difference between this embodiment and embodiment 1 is that the flow rate setting value is 2 meters per second, the controller acquires the flow rate value measured by the flow rate measuring unit, and if the flow rate value is 1 meter per second, which is less than the flow rate setting value of 2 meters per second, the controller determines that the measurement point is located in the edge water area.

[0079] If the flow rate value is 2.5 meters per second, which is greater than the flow rate setting value of 2 meters per second, the controller determines that the measurement point is located in the central water area.

[0080] The flow rate value is the flow rate of the water flow; the flow rate setting value is positively correlated with the average value of the past flow rate.

[0081] In one embodiment, when the average value of the past flow rate is 1 meter per second, the flow rate setting value is 1.5 meters per second;

[0082] When the average value of the past flow rate is 2 meters per second, the flow rate setting value is 2.5 meters per second;

[0084] Specifically, the controller acquires the water level value of the central water area measured by the height unit and compares the water level value with the first water level preset value and the second water level preset value;

[0085] If the water level value is less than the first water level preset value, the controller determines that the water flow of the measurement point is reduced, and the alarm unit issues an audible and visual alarm;

[0086] If the water level value is not less than the first water level preset value and less than the second water level preset value, the controller determines that the water flow of the measurement point is normal;

[0087] If the water level value is not less than the second water level preset value, the controller determines that the water flow of the measurement point is increased, and the alarm unit issues an audible and visual alarm;

[0088] Embodiment 3, on the basis of embodiment 2, the difference between this embodiment and embodiment 2 is that the first water level preset value is 10 meters, the second water level preset value is 20 meters, the controller acquires the water level value of the central water area measured by the height unit, and if the water level value is 8 meters, which is less than the first water level preset value of 10 meters, the controller determines that the water flow of the measurement point is reduced, and the alarm unit issues an audible and visual alarm;

[0089] If the water level value is 15 meters, which is greater than the first water level preset value of 10 meters and less than the second water level preset value of 20 meters, the controller determines that the water flow of the measurement point is normal;

[0090] If the water level value is 22 meters greater than the second water level preset value 20 meters, the controller determines that the water flow at the measurement point is increased, and the alarm unit issues an audible and visual alarm.

[0091] The water level value is the water depth; the first water level preset value and the second water level preset value are positively correlated with the past water level average value.

[0092] In one embodiment, when the past water level average value is 10 meters, the first water level preset value is 5 meters, and the second water level preset value is 15 meters.

[0093] When the past water level average value is 15 meters, the first water level preset value is 10 meters, and the second water level preset value is 20 meters.

[0094] When the past water level average value is 20 meters, the first water level preset value is 15 meters, and the second water level preset value is 25 meters.

[0095] Specifically, in the state where the controller determines that the water flow at the measurement point is increased, the ranging unit measures the width value of the water flow, the controller acquires the width value and compares the width value with a width preset value;

[0096] If the width value is less than the width preset value, the controller determines that the water flow width is normal.

[0097] If the width value is not less than the width preset value, the controller determines that the water flow width is too wide, and the alarm unit issues an audible and visual alarm.

[0098] In embodiment 4, based on embodiment 3, the difference between the two is that the width preset value is 50 meters, and in the state where the controller determines that the water flow at the measurement point is increased, the ranging unit measures the width value of the water flow, the controller acquires the width value, and if the width value is 24 meters less than the width preset value 50 meters, the controller determines that the water flow width is normal.

[0099] If the width value is 60 meters greater than the width preset value 50 meters, the controller determines that the water flow width is too wide, and the alarm unit issues an audible and visual alarm.

[0100] The width preset value is positively correlated with the past width average value.

[0101] In one embodiment, when the past width average value is 5 meters, the width preset value is 10 meters.

[0102] When the past width average value is 10 meters, the width preset value is 15 meters.

[0103] When the past width average value is 15 meters, the width preset value is 20 meters.

[0104] Specifically, the hydrological parameters obtained by the ADCP detector can effectively monitor various hydrological parameters of the water flow, filter and screen effective data, improve the detection accuracy, and further improve the stability and practicability of the ADCP detector.

[0105] Specifically, when the controller determines that the measurement point is located in the edge water area state, the cable traveler drives the ADCP detector at a general speed.

[0106] Specifically, when the controller determines that the measurement point is located in the center water area state, the cable traveler drives the ADCP detector at a working speed.

[0107] The working speed is less than the general speed.

[0108] In the embodiment 4, the difference between the peak value A and the trough value B is 1 meter, the amplitude is 1 meter greater than the amplitude preset value, the controller judges that the ADCP detector is unstable, and the cable traveler reduces the moving speed of the ADCP detector to 0.05 meters per second.

[0109] Please refer to Figure 4 As shown in the curve diagram of the height value of the embodiment of the application, when the height unit detects that the height value is in a periodic change state, the measured height value is plotted into a curve diagram, the controller calculates the amplitude of the height value according to the curve diagram and compares the amplitude with an amplitude preset value.

[0110] If the amplitude is less than the amplitude preset value, the controller judges that the ADCP detector is stable.

[0111] If the amplitude is not less than the amplitude preset value, the controller judges that the ADCP detector is unstable, and the cable traveler reduces the moving speed of the ADCP detector.

[0112] Embodiment 5: Please continue to refer to Figure 4 As shown in the curve diagram of the height value of the embodiment of the application, when the height unit detects that the height value is in a periodic change state, the measured height value is plotted into a curve diagram, the controller calculates the amplitude of the height value according to the curve diagram and compares the amplitude with an amplitude preset value.

[0113] In the embodiment 4, the difference between the peak value A and the trough value B is 1 meter, the amplitude is 1 meter greater than the amplitude preset value, the controller judges that the ADCP detector is unstable, and the cable traveler reduces the moving speed of the ADCP detector to 0.05 meters per second.

[0114] If the difference between the peak value A and the trough value B is 1 meter, the amplitude is 1 meter greater than the amplitude preset value, the controller judges that the ADCP detector is unstable, and the cable traveler reduces the moving speed of the ADCP detector to 0.05 meters per second.​

[0115] The amplitude preset value is positively correlated with the cable length.

[0116] In one embodiment, when the cable length is 10 meters, the amplitude preset value is 0.5 meters;

[0117] When the cable length is 20 meters, the amplitude preset value is 0.8 meters;

[0118] When the cable length is 30 meters, the amplitude preset value is 1 meter.

[0119] Specifically, when the controller determines that the ADCP detector is in a stable state, the controller calculates the mean value as the height value according to the curve graph.

[0120] Embodiment 6: Based on embodiment 5, the difference between the two is that, when the controller determines that the ADCP detector is in a stable state, the peak value A is 0.1 meters, the trough value B is 0.1 meters, and the mean value is (0.1+0.1) / 2=0.1 meters. At this time, the height value is 0.1 meters.

[0121] Specifically, the combination of the curve graph and the data analysis method can more accurately obtain the working state of the ADCP detector, effectively improve the accuracy of hydrological data detection, and further improve the stability and practicality of the ADCP detector.
