Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0037] See also Figure 1 The present invention provides a method for implementing energy monitoring of vibroflotation construction, comprising the following steps:

[0038] S1. Obtain the water pressure and water volume, the electricity consumption, and the gas pressure and gas volume used in the first vibroflotation construction stage;

[0039] The water pressure and water volume, the electricity consumption, and the gas pressure and gas volume used in the first vibroflotation construction stage are obtained in step S1, including:

[0040] Acquire sensor data of the voltage sensor, current sensor, pressure sensor, flow sensor, air pressure sensor, and air flow sensor, and determine the water pressure and water volume, electricity consumption, and air pressure and air volume of the first vibroflotation construction phase based on the sensor data;

[0041] The water pressure and water volume, electricity consumption, and gas pressure and gas volume used in the first vibroflotation construction stage may include:

[0042] In the first vibro-construction stage, the total water consumption, electricity consumption and gas consumption of each construction unit (such as vibro-construction piles in vibro-construction) is calculated.

[0043] The power supply device is used to control the amount of electricity consumed in the first and second vibro-impact construction stages. The sensors arranged in the power supply device include a voltage sensor for monitoring the power supply voltage and a current sensor for monitoring the power supply current.

[0044] The high-pressure water supply device is used to control the amount of water consumed in the first and second vibration construction stages. The sensors arranged in the high-pressure water supply device include a pressure sensor for monitoring the water pressure and a flow sensor for monitoring the water amount.

[0045] The high-pressure air supply device is used to control the amount of air consumed in the first and second vibro-impact construction stages, and the sensors in the high-pressure water supply device include an air pressure sensor for monitoring the air pressure and an air flow sensor for monitoring the air volume.

[0046] The voltage sensor, current sensor, pressure sensor, flow sensor, air pressure sensor, air flow sensor, vibro-voltage sensor, and vibro-current sensor are all connected to the host.

[0047] Through external sensors and the host, the water pressure, air pressure, airflow, water volume, voltage, current and no-load current of the vibrator are monitored to see if they are normal. During the operation of the power supply device and the high-pressure water supply device, the current sensor and voltage sensor inside the power supply device will send the operating current and voltage data of the power supply device to the host. The water pressure sensor and flow sensor in the high-pressure water supply device will send the water pressure and water flow data during the operation of the high-pressure water supply device to the host, and collect and determine the amount of each energy consumed in the first vibratory construction stage.

[0048] In some embodiments, the solution further includes obtaining the depth and hole-making speed of the construction unit in the first vibration construction stage, and establishing a relationship between the depth and hole-making speed and the amount of each energy consumed.

[0049] S2. Determine the amount of each energy consumed in the first vibroflotation construction stage based on the water pressure, water volume, electricity, air pressure and air volume;

[0050] The host is connected with the vibrator, the high-pressure water supply device, the high-pressure air supply device and the power supply device, and the vibrator, the high-pressure water pump of the high-pressure water supply device and the power supply device are used to control the power supply box through the host;

[0051] In the first vibration construction stage, when the vibrator has not penetrated, the main engine is used to control the high-pressure water supply device to increase the water supply frequency and pressure.

[0052] See also Figure 2 The voltage, current, pressure, flow, air pressure and airflow in the first and second construction of the construction unit are detected through voltage sensors, current sensors, pressure sensors, flow sensors, air pressure sensors and airflow sensors, and the construction unit can also realize detection by motion sensors, vibro-surge voltage sensors and vibro-surge current sensors.

[0053] For example, during the operation of the vibrator to make a hole, the motion sensor will transmit the real-time depth data of the vibrator and the real-time hole-making speed data of the vibrator to the host, and the voltage sensor and current sensor inside the vibrator will transmit the voltage and current data of the vibrator during operation to the host. During the operation of the vibrator, the host will compare and calculate the operating current and voltage data of the power supply device with the voltage and current data during operation according to the mechanical energy conservation formula: Ek1+Ep1=Ek2+Ep2, that is, the power output of the power supply device = the power consumed by the vibrator +The work done by the vibrator on the soil is used to calculate the energy consumed by the vibrator in its operation. The energy required for hole making at this depth is calculated based on the vibrator depth data transmitted by the motion sensor and recorded. When the output voltage and current of the power supply device and the output water pressure and water flow of the high-pressure water supply device remain unchanged, the hole making speed of the vibrator is relatively fast. The output voltage and current of the power supply device are reduced through the host control so that the output water pressure and water flow of the high-pressure water supply device remain unchanged. The hole making speed of the vibrator is still relatively fast, which means that the soil at this depth is relatively loose. The output water pressure and water flow of the high-pressure water supply device should be reduced through the host control to keep the hole-making speed of the vibrator between 2.5m / min and 3m / min. When the output voltage and current of the power supply device and the output water pressure and water flow of the high-pressure water supply device remain unchanged, the hole-making speed of the vibrator is slow. The output voltage and current of the power supply device are increased through the host control to keep the output water pressure and water flow of the high-pressure water supply device unchanged. The hole-making speed of the vibrator is still slow, which means that the soil at this depth is relatively compact. At this time, the high-pressure water supply should be increased through the host control. The output water pressure and water flow of the water device are used to keep the hole-making speed of the vibrator between 2.5m / min and 3m / min. If the hole-making speed of the vibrator is still slow when the output water pressure and water flow of the high-pressure water supply device are increased to keep the output voltage and current of the power supply device unchanged, it means that the stratum at this depth may have rocks that prevent the vibrator from making holes. The output power of the power supply device and the high-pressure water supply device is controlled by the host, and then the output power of the power supply device and the high-pressure water supply device is adjusted accordingly according to the vibrator depth and hole-making speed, thereby stably increasing the hole-making efficiency;

[0054] S3, obtaining the preset amount of each energy source in the second vibro-construction stage; and the amount of each energy source consumed in the first vibro-construction stage;

[0055] After the first vibro-flotation construction phase, the host is used to control the high-pressure water supply device, and the frequency and pressure of the high-pressure water supply device are preset according to the depth preset given curve. At the same time, the frequency conversion and voltage conversion of the high-pressure water pump are controlled wirelessly;

[0056] S4. Based on the amount of each energy consumed in the first vibro-flotation construction stage, the preset amount of each energy in the second vibro-flotation construction stage is adjusted. Specifically, the adjustment can be based on factors such as geological characteristics.

[0057] The construction unit is provided with a motion sensor for monitoring the vibrothelium depth and hole-making speed in the first and second vibrothelium construction stages, a vibrothelium voltage sensor for monitoring the operating voltage of the construction unit, and a vibrothelium current sensor for monitoring the operating current of the vibrothelium. The sensing data of the motion sensor is obtained, and the depth and hole-making speed of the construction unit in the first vibrothelium construction stage are determined based on the sensing data.

[0058] In step S4, adjusting the preset amount of each energy source in the second vibro-construction stage based on the amount of each energy source consumed in the first vibro-construction stage includes:

[0059] Based on the depth and hole-making speed of the second vibro-construction construction unit, combined with the relationship between the depth and hole-making speed and the amount of each energy consumed, the working voltage and current of the construction unit are adjusted based on the vibro-construction voltage sensor and the vibro-construction current sensor.

[0060] During the first and second vibro-impact construction stages, the high-pressure water supply device is controlled by the host, and the frequency and pressure of the high-pressure water supply device are preset according to the depth preset given curve.

[0061] Exemplarily, the energy required for punching hole 1 in the first vibro-impacting construction stage and punching hole 2 in the second vibro-impacting construction stage is obtained, and the power of the control appliance is 45KW, the rated current is 86A, the rated voltage is 380V+10% of three-phase AC, the rated frequency is 50HZ, the compaction current is 50A, the rated power of the water pump motor is 22KW, the water pressure during hole forming is 0.3-0.5MP, and the water pressure during hole forming is 0.5-0.8MP. The power supply device is used to control the amount of electricity consumed during the vibro-impacting construction stage. Several bypasses are arranged in the power supply device. The sensors arranged in the power supply device include a voltage sensor for monitoring the power supply voltage of the power supply box and a current sensor for monitoring the power supply current of the power supply box; the high-pressure water supply device is used to control the amount of water consumed during the vibro-impacting construction stage. The sensors in the high-pressure water supply device include a pressure sensor for monitoring water pressure and a flow sensor for monitoring water volume; the high-pressure air supply device is used to control the amount of air consumed during the vibratory construction phase. The sensors in the high-pressure water supply device include a pressure sensor for monitoring air pressure and an air flow sensor for monitoring air volume; the vibrator is equipped with a motion sensor for monitoring the hole-making speed and depth of the vibrator, a voltage sensor for monitoring the operating voltage of the vibrator, and a current sensor for monitoring the operating current of the vibrator; all sensors are wirelessly connected to the host. The voltage sensor refers to a sensor that can sense the measured voltage and convert it into a usable output signal. The two voltage sensors are LV1000 / SP13, which use the closed loop (compensation) of the Hall principle and comply with UL 94-V0 standard insulating shell, current sensor refers to the information that can sense the measured current, and can transform the information sensed by the monitoring into an electrical signal or other required form of information output that meets certain standards according to certain rules. The two current sensor models are ACS759LCB-100B-PFF-T. The working principle of the water pressure sensor is that the pressure of the measured water pressure directly acts on the diaphragm of the sensor, causing the diaphragm to produce a micro-displacement proportional to the water pressure, causing the resistance value of the sensor to change. The model of the water pressure sensor is KGYL-002, and the flow sensor model is DN200. The water flow rotor assembly is mainly composed of a turbine switch shell, a magnetic rotor, and a brake ring. When the water flow switch method is used, its performance is better than the mechanical pressure differential disc structure, and the size is significantly reduced. When the water flows through the turbine switch shell, it drives the magnetic rotor to rotate. When different magnetic poles are close to the Hall element, the Hall element is turned on, and when they leave, the Hall element is disconnected. Thus, the rotor speed can be measured, and the water flow rate can be measured by the rotor speed. The motion sensor can specifically include a GPS module, a distance sensor (such as an ultrasonic radar, a laser radar, etc.), a gyroscope, etc., which are mainly used to monitor the hole-making speed of the vibrator, and the air pressure and air flow of the high-pressure air supply device during use are collected through an air pressure sensor and an air flow sensor;

[0062] After a point construction is carried out, the host can control the high-pressure water supply device to preset the frequency and pressure of the high-pressure water supply device according to the depth preset given curve, and can also synchronously realize the frequency and voltage conversion wireless control of the high-pressure water pump.

[0063] The vibrator and host involved in this embodiment can be freely configured according to the actual application scenario, and the host controls the operation of the vibrator, the high-pressure water supply device and the power supply device using methods commonly used in the prior art.
