[0039] The present invention will be further described in detail below in conjunction with the accompanying drawings and embodiments. It is to be understood that the specific embodiments described herein are only used to explain the present invention, rather than to limit the present invention. It should also be noted that, for ease of description, only parts related to the present invention, rather than all structures, are shown in the accompanying drawings.

[0040] The embodiment of the present invention provides a dynamic water level control device, which can be used to control the water level of a well in a foundation pit, thereby achieving foundation pit dewatering. Figure 1 A schematic diagram of the structure of a water level dynamic control device provided by an embodiment of the present invention, Figure 2A schematic diagram of the installation of a water level dynamic control device provided by an embodiment of the present invention is shown in FIG. Figure 1 and Figure 2 As shown, the water level dynamic control device includes a water level monitoring module 110 , a water level control device 120 and a control module 130 .

[0041] The water level control device 120 is arranged in the water well, the output end of the water level monitoring module 110 is connected to the first input end of the control module 130, the output end of the water level control device 120 is connected to the second input end of the control module 130, and the output end of the control module 130 is connected to the input end of the water level control device 120.

[0042] The water level monitoring module 110 is used to detect the real-time water level in the water well and send the real-time water level of the water well to the control module 130; the control module 130 is used to determine the water level change rate according to the real-time water level of the water well, and control the power frequency of the water level control device 120 according to the real-time water level of the water well and the water level change rate; the water level control device 120 is used to feed back the current power frequency to the control module and control the water level in the water well with the current power frequency.

[0043] Among them, foundation pit dewatering refers to the dewatering work done when the groundwater level is higher than the excavation ground during the excavation of the foundation pit, and the groundwater will continue to seep into the pit to ensure that the foundation pit can be constructed under dry conditions, to prevent slope instability, foundation sand flow, pit bottom uplift, pit bottom pipe burst and foundation bearing capacity reduction. For example, the foundation pit dewatering can usually be carried out by open ditch plus water collection well dewatering, light well point dewatering, jet well point dewatering, electro-osmosis well point dewatering, deep well well point dewatering and other methods. Figure 2 The water well in the embodiment of the present invention may be a pressure water level dewatering well located in a foundation pit, and the embodiment of the present invention is not limited to this.

[0044] Specifically, refer to Figure 2 The water level monitoring module 110 can be an immersion type water level monitoring device. The water level monitoring module 110 is placed in a water well and contacts the water surface in the water well to detect the real-time water level in the water well. In addition, the water level monitoring module 110 can also be a non-contact type water level monitoring device. The water level monitoring module 110 is not placed in the water well, but can also detect the real-time water level in the water well. The water level monitoring module 110 can be a water level sensor, so as to detect the real-time water level in the water well. The water level control device 120 is set at an appropriate height below the water surface in the water well, and can control the water level in the water well by extracting water from the water well. In addition, the water level control device 120 has different pumping speeds under different power supply frequencies. Therefore, by controlling the power supply frequency of the water level control device 120, the pumping rate of the water level control device 120 can be controlled.

[0045] In the specific water level control process, the control module 130 determines the water level change rate according to the real-time water level of the water well, and controls the power frequency of the water level control device 120 according to the real-time water level of the water well and the water level change rate, which is equivalent to the control module 130 controlling the pumping rate of the water level control device 120 according to the real-time water level of the water well and the water level change rate. It should be noted that the process in which the control module 130 controls the power frequency of the water level control device 120 according to the real-time water level of the water well and the water level change rate can control the power frequency of the water level control device 120 only according to the real-time water level of the water well, and also control the power frequency of the water level control device 120 according to the real-time water level of the water well and the water level change rate. Optionally, the control module 130 controls the pumping rate of the water level control device 120 only according to the real-time water level of the well. For example, when the real-time water level of the well is greater than the preset target water level, the pumping rate of the water level control device 120 can be controlled to increase to lower the water level; Optionally, the control module 130 controls the pumping rate of the water level control device 120 according to the real-time water level and the water level change rate of the well at the same time. For example, when the water level change rate is greater than or equal to 0 and the water level of the well is higher than the preset target water level, it indicates that the water level in the well is increasing, and the current pumping rate of the water level control device 120 cannot keep the water level of the well at the preset target water level. It is necessary to increase the pumping rate of the water level control device 120 by increasing the frequency so that the water level in the well drops rapidly to achieve control of the water level in the well. In addition, by controlling the power supply frequency of the water level control device 120 through the water level change rate, the water level in the well can be predicted in advance, and when the water level in the well changes rapidly, the water level in the well can still be dynamically controlled. Optionally, the control module 130 can also control the pumping rate of the device 120 through the real-time water level and water level change rate of the well in combination with the neural network.

[0046] By controlling the pumping rate of the water level control device 120 according to the real-time water level and water level change rate of the well through the control module 130, dynamic control of the water level in the well can be achieved, solving the problems of poor real-time monitoring, low degree of automation and poor environmental adaptability in the prior art, and achieving precise control of the water level in the well, thereby reducing the impact of water level changes in the well on the surrounding environment and improving the automation and intelligence level of the system.

[0047] The embodiment of the present invention provides a dynamic water level control device, which includes a water level monitoring module, a water level control device and a control module; the water level monitoring module and the water level control device are both arranged in a water well, the output end of the water level monitoring module is connected to the first input end of the control module, the output end of the water level control device is connected to the second input end of the control module, and the output end of the control module is connected to the input end of the water level control device; the water level monitoring module is used to detect the real-time water level in the water well, and send the real-time water level of the water well to the control module, so as to realize accurate real-time detection of the water level of the water well located in the foundation pit; the control module is used to determine the water level change rate according to the real-time water level of the water well, and control the power frequency of the water level control device according to the real-time water level of the water well and the water level change rate, the water level control device is used to feed back the current power frequency to the control module, and control the water level in the water well with the current power frequency, so as to realize accurate control of the water level of the water well, thereby reducing the impact of the water level change in the water well on the surrounding environment, and improving the automation and intelligence level of the system.

[0048] The embodiment of the present invention also provides another dynamic water level control device. Figure 3 A schematic diagram of the structure of another water level dynamic control device provided by an embodiment of the present invention is shown in FIG. Figure 3 As shown, optionally, the water level control device 120 includes a water pump 1201 and a frequency converter 1202; the output end of the frequency converter 1202 serves as the output end of the water level control device 120, and the input end of the frequency converter 1202 serves as the input end of the water level control device 120; the current input end of the water pump 1201 is electrically connected to the current output end of the frequency converter 1202, and the water pump 1201 is used to extract water from the well.

[0049] The control module 130 is specifically used to control the power frequency of the frequency converter 1202 according to the real-time water level and water level change rate of the well; the frequency converter 1202 is used to feed back the current power frequency to the control module 130, and control the water pump 1201 to work with the current power frequency.

[0050] Among them, the water pump 1201 is a variable frequency submersible pump, and the pumping speed is different under different power supply frequencies.

[0051] Specifically, the pumping speed of the water pump 1201 is different under different power supply frequencies. Therefore, by controlling the power supply frequency output by the frequency converter 1202, the pumping rate of the water pump 1201 can be controlled. In the specific water level control process, the control module 130 determines the water level change rate according to the real-time water level of the water well, and controls the power supply frequency output by the frequency converter 1202 to the water pump 1201 according to the real-time water level of the water well and the water level change rate, which is equivalent to the control module 130 controlling the pumping rate of the water pump 1201 according to the real-time water level of the water well and the water level change rate, thereby realizing dynamic control of the water level in the water well, so that no matter how the water level in the water well changes dynamically, water in the water well can be pumped out by the water pump 1201, so that the water level in the water well is within the preset water level range.

[0052] Optional, continue to refer to Figure 3 The dynamic water level control device also includes an analog-to-digital conversion module 140; the input end of the analog-to-digital conversion module 140 is connected to the output end of the frequency converter 1202, and the output end of the analog-to-digital conversion module 140 is connected to the output end of the control module 130; the analog-to-digital conversion module 140 is used to perform analog-to-digital conversion on the current power supply frequency fed back by the frequency converter 1202 and send it to the control module 130.

[0053] Specifically, the analog-to-digital conversion module 140 performs analog-to-digital conversion on the current power frequency fed back by the inverter 1202 and sends it to the control module 130, so that the control module 130 can easily determine whether it is necessary to adjust the current power frequency of the inverter 1202 to achieve control of the pumping speed of the water pump 1201.

[0054] In addition, the water level monitoring module 110 can be an integrated high-precision water level sensor, and the control module 130 has an integrated modular serial port function. The water level monitoring module 110, the frequency converter 1202, and the analog-to-digital conversion module 140 are all connected to the control module 130 through the USB serial port, and can realize functions such as frequency control, frequency feedback, and water level reading. During use, the water level monitoring module 110 and the water level control device 120 can be placed in the water well, and then the power supply frequency control, frequency feedback, and the serial port number of the water level monitoring module 110 are set. The control water level target is set according to the current water level value in the water well, and the upper and lower limit tolerances are set. The moving window is used to filter the water level change rate. The control module 130 adjusts the frequency of the variable frequency submersible pump according to the water level change rate (the frequency adjustment control method is not limited) to achieve accurate control of the water level of the water well, thereby reducing the impact of the water level change in the water well on the surrounding environment, and improving the automation and intelligence level of the system.

[0055] Optional, continue to refer to Figure 3The dynamic water level control device also includes an early warning module 150; the input end of the early warning module 150 is connected to the early warning signal output end of the control module 130; the control module 130 is also used to send an early warning signal to the early warning module 150 according to the real-time water level and water level change rate of the well, and the early warning module 150 is used to issue an early warning according to the early warning signal.

[0056] Specifically, the early warning module 150 may have sound and light early warning functions, and the control module 130 may also configure different early warning information according to the real-time water level and water level change rate of the well, and send the corresponding early warning signal to the early warning module 150, so that the early warning module 150 issues early warning information of different specifications, thereby enabling users to promptly discover water level changes in the well.

[0057] Optionally, the warning signal includes a first warning signal, a second warning signal, a third warning signal and a fourth warning signal; the warning module 150 is also used to issue different warning information according to different warning signals.

[0058] The control module 130 is specifically used to increase the power frequency of the water level control device 120 and send a first warning signal to the warning module 150 when the real-time water level of the water well is greater than the preset water level range and the water level change rate is greater than or equal to 0; the control module 130 is specifically used to maintain the power frequency of the water level control device 120 and send a second warning signal to the warning module 150 when the real-time water level of the water well is greater than the preset water level range and the water level change rate is less than 0; the control module 130 is specifically used to reduce the power frequency of the water level control device 120 and send a third warning signal to the warning module 150 when the real-time water level of the water well is less than the preset water level range and the water level change rate is less than or equal to 0; the control module 130 is specifically used to maintain the power frequency of the water level control device 120 and send a fourth warning signal to the warning module 150 when the real-time water level of the water well is less than the preset water level range and the water level change rate is greater than 0.

[0059] Specifically, when the real-time water level in the well is greater than the preset water level range and the water level change rate is greater than or equal to 0, the control module 130 indicates that the water level in the well is increasing rapidly and is greater than the preset water level range. The power frequency of the water level control device 120 needs to be increased to speed up the pumping speed. When the real-time water level of the well is greater than the preset water level range and the water level change rate is less than 0, the control module 130 indicates that although the water level is greater than the preset water level range, the water level in the well is decreasing. The power frequency of the water level control device 120 is maintained, so that the real-time water level of the well is within the preset water level range; when the real-time water level of the well is less than the preset water level range and the water level change rate is less than or equal to 0, the control module 130 reduces the power frequency of the water level control device 120 so that the real-time water level of the well slowly rises to the preset water level range; the control module 130 is specifically used to maintain the power frequency of the water level control device 120 when the real-time water level of the well is less than the preset water level range and the water level change rate is greater than 0, so that the real-time water level of the well slowly rises to the preset water level range. In addition, when the real-time water level of the well is within the preset water level range, the control module 130 can fine-tune the power frequency of the water level control device 120 so that the water level change rate is equal to 0, thereby ensuring that the real-time water level of the well is always within the preset water level range. Realize dynamic control of the water level in the well, solve the problems of poor real-time monitoring, low degree of automation and poor environmental adaptability in the existing technology, realize precise control of the water level in the well, thereby reducing the impact of water level changes in the well on the surrounding environment and improving the automation and intelligence level of the system.

[0060] Optionally, the dynamic water level control device also includes a flow monitoring module.

[0061] Specifically, the flow monitoring module is communicatively connected with the control module 130. The flow monitoring module can be set at the water outlet of the water level control device 120. The flow monitoring module is used to monitor the pumping rate of the water level control device 120, and feed back the monitored pumping rate of the water level control device 120 to the control module 130, so that the control module 130 can further control the power frequency of the water level control device 120 according to the pumping rate of the water level control device 120, as well as the real-time water level and water level change rate feedback of the well, so that the pumping rate of the water level control device 120 meets the current pumping demand.

[0062] Optional, continue to refer to Figure 3 The dynamic water level control device also includes a cloud platform 160; the cloud platform 160 is in communication connection with the control module 130, and the control module 130 is also used to upload the real-time water level of the well, the water level change rate and the power frequency of the water level control device 120 to the cloud platform 160.

[0063] Specifically, by uploading the real-time water level of the well, the water level change rate and the power frequency of the water level control device 120 to the cloud platform 160 through the control module 130, the real-time water level of the well can be remotely monitored, thereby improving the intelligence level of the system.

[0064] The embodiment of the present invention provides a dynamic water level control device, which detects the real-time water level in a water well through a water level monitoring module, and sends the real-time water level of the water well to a control module, so as to realize accurate real-time detection of the water level of the water well located in a foundation pit; the control module determines the water level change rate according to the real-time water level of the water well, and controls the power frequency of the water level control device according to the real-time water level of the water well and the water level change rate; the water level control device feeds back the current power frequency to the control module, and controls the water level in the water well with the current power frequency, so as to realize accurate control of the water level of the water well, thereby reducing the impact of the water level change in the water well on the surrounding environment, and improving the automation and intelligence level of the system, and solving the problems of poor real-time monitoring, low degree of automation and poor environmental adaptability in the prior art.

[0065] The embodiment of the present invention further provides a dynamic water level control method, which is applied to a dynamic water level control device that implements any embodiment of the present invention. Figure 4 FIG. 1 is a flow chart of a dynamic water level control method in an embodiment of the present invention. Figure 4 As shown, the method includes:

[0066] S110: Obtain the real-time water level of the water well and the current power frequency in the water level control device.

[0067] Specifically, refer to Figure 1 , the real-time water level of the well is obtained through the water level monitoring module 110, and the current power frequency in the water level control device 120 is obtained at the same time to determine whether the current power frequency in the water level control device 120 needs to be adjusted.

[0068] S120: Determine the water level change rate according to the real-time water level of the well.

[0069] Specifically, the water level change rate can be obtained by the change amplitude of the water level in the water well over time. For example, the change height of the water level in the water well at time T is X, and the water level change rate V=X / T. By determining the water level change rate, the change trend of the water level in the water well can be determined, so as to adjust the power frequency of the water level control device 120 in advance and change the pumping speed of the water level control device 120 in advance to cope with the change trend of the water level in the water well. In addition, a moving window can be used to filter the water level change rate to improve the accuracy of the water level change rate calculation.

[0070] S130. Control the power frequency of the water level control device according to the real-time water level and water level change rate of the well.

[0071] Specifically, the water level control device 120 pumps water at different speeds under different power supply frequencies. Therefore, by controlling the power supply frequency of the water level control device 120, the pumping rate of the water level control device 120 can be controlled. In the specific water level control process, the water level change rate is determined according to the real-time water level of the well. The power supply frequency of the water level control device 120 is controlled according to the real-time water level of the well and the water level change rate, which is equivalent to controlling the pumping rate of the water level control device 120 according to the real-time water level of the well and the water level change rate. The process of controlling the power supply frequency of the water level control device 120 according to the real-time water level of the well and the water level change rate can be performed. The power supply frequency of the water level control device 120 can be controlled only according to the real-time water level of the well, or the water level control device can be controlled only according to the water level change rate. The power frequency of the water level control device 120 can also be controlled according to the real-time water level and the water level change rate of the well. For example, when the water level change rate is greater than or equal to 0 and the water level in the well is higher than the preset target water level, it indicates that the water level in the well is increasing. The current pumping rate of the water level control device 120 cannot keep the water level in the well at the preset target water level. It is necessary to increase the pumping rate of the water level control device 120 by increasing the frequency so that the water level in the well drops rapidly and the water level in the well is controlled. In addition, by controlling the power frequency of the water level control device 120 according to the water level change rate, the water level in the well can be predicted in advance, and the water level in the well can still be dynamically controlled when the water level in the well changes rapidly. By controlling the pumping rate of the water level control device 120 according to the real-time water level and water level change rate of the well, dynamic control of the water level in the well can be achieved, solving the problems of poor real-time monitoring, low degree of automation and poor environmental adaptability in the prior art, and achieving precise control of the well water level, thereby reducing the impact of water level changes in the well on the surrounding environment and improving the automation and intelligence level of the system.

[0072] An embodiment of the present invention provides a dynamic water level control method, which includes obtaining the real-time water level of a water well and the current power supply frequency in a water level control device, determining the water level change rate according to the real-time water level of the water well, and controlling the power supply frequency of the water level control device according to the real-time water level of the water well and the water level change rate, so that the pumping speed of the water level control device is controlled by the real-time water level of the water well and the water level change rate, so as to achieve precise control of the water level of the water well, thereby reducing the impact of water level changes in the water well on the surrounding environment and improving the automation and intelligence level of the system.

[0073] Optionally, in the dynamic water level control method provided in the embodiment of the present invention, the power frequency of the water level control device is controlled according to the real-time water level and water level change rate of the well, including:

[0074] The power frequency of the water level control device is controlled only according to the real-time water level of the water well, or the power frequency of the water level control device is controlled according to the real-time water level of the water well and the water level change rate at the same time.

[0075] Specifically, in the process of controlling the power frequency of the water level control device 120 according to the real-time water level and the water level change rate of the water well, the power frequency of the water level control device 120 may be controlled only according to the real-time water level of the water well, or only according to the water level change rate, or the power frequency of the water level control device 120 may be controlled according to both the real-time water level of the water well and the water level change rate. In addition, the power frequency of the water level control device 120 may be controlled in combination with a neural network, thereby improving the scope of application of the dynamic water level control method.

[0076] Optionally, in the dynamic water level control method provided in the embodiment of the present invention, the power frequency of the water level control device is controlled according to the real-time water level and water level change rate of the well, including:

[0077] When the real-time water level of the well is greater than the preset water level range and the water level change rate is greater than or equal to 0, the power frequency of the water level control device is increased.

[0078] When the real-time water level of the well is greater than the preset water level range and the water level change rate is less than 0, the power frequency of the water level control device is maintained.

[0079] When the real-time water level of the water well is less than the preset water level range and the water level change rate is less than or equal to 0, the power frequency of the water level control device is reduced.

[0080] When the real-time water level of the well is less than the preset water level range and the water level change rate is greater than 0, the power frequency of the water level control device is maintained.

[0081] When the real-time water level of the well is within the preset water level range, the water level change rate is made equal to 0 by controlling the power frequency of the water level control device.

[0082] Specifically, by controlling the water level according to the real-time water level and the water level change rate of the well, the changing trend of the water level in the well can be determined, so that the pumping speed of the water level control device 120 can be changed in advance by adjusting the power frequency of the water level control device 120 in advance to cope with the changing trend of the water level in the well. For example, when the real-time water level of the well is greater than the preset water level range, and the water level change rate is greater than or equal to 0, the water level in the well is increasing rapidly and is greater than the preset water level range, and the power frequency of the water level control device 120 needs to be increased to speed up the pumping speed. When the real-time water level of the well is greater than the preset water level range and the water level change rate is less than 0, it indicates that although the water level is greater than the preset water level range, the water level in the well is decreasing. Maintaining the power frequency of the water level control device 120 can keep the real-time water level of the well within the preset water level range; when the real-time water level of the well is less than the preset water level range and the water level change rate is less than or equal to 0, reduce the power frequency of the water level control device 120 so that the real-time water level of the well slowly rises to the preset water level range; specifically, when the real-time water level of the well is less than the preset water level range and the water level change rate is greater than 0, maintain the power frequency of the water level control device 120 so that the real-time water level of the well slowly rises to the preset water level range. In addition, when the real-time water level of the well is within the preset water level range, the power frequency of the water level control device 120 can be fine-tuned so that the water level change rate is equal to 0, thereby ensuring that the real-time water level of the well is always within the preset water level range. Realize dynamic control of the water level in the well, solve the problems of poor real-time monitoring, low degree of automation and poor environmental adaptability in the existing technology, realize precise control of the water level in the well, thereby reducing the impact of water level changes in the well on the surrounding environment and improving the automation and intelligence level of the system.

[0083] In the dynamic water level control method provided in the embodiment of the present invention, before controlling the power frequency of the water level control device according to the real-time water level and the water level change rate of the well, the method further includes:

[0084] The preset water level range is set according to the real-time water level of the well obtained for the first time.

[0085] Specifically, the approximate groundwater level in the current area can be determined based on the real-time water level of the well obtained for the first time. Based on this, a preset water level range can be set, and the upper and lower limit tolerances of the preset water level range can be set so that the water level of the well does not affect the construction in the foundation pit within a certain surrounding area.

[0086] The embodiment of the present invention further provides a storage medium containing computer executable instructions, which are used to execute the dynamic water level control method of any embodiment of the present invention when executed by a computer processor, including:
