After the data processing unit receives the pulse signal, the count is increased by one, thereby recording the number of hammer strikes in real time;

[0012] Calculation of the depth of the pile: The laser distance sensor measures the height from the bottom of the hammer to the ground in real time. The data processing unit calculates the downward displacement of the hammer based on the continuous height data to determine the depth of the pile.

[0028] like Figure 1 As shown, an embodiment of the present invention provides a system for automatically calculating the number of hammer blows and the depth of penetration of a pile driver, comprising:

[0029] The inductive sensor is installed on the side of the hammer head base of the diesel hammer pile driver to detect the up and down movement of the hammer head. When the hammer head completes a complete up and down movement cycle (i.e. one hammering), the inductive sensor generates a pulse signal;

[0030] A laser distance sensor is installed under the hammer base to measure the height of the bottom of the hammer from the ground in real time. The laser distance sensor collects height data at a predetermined time interval.

[0031] The data processing unit includes a microprocessor, a data storage module connected to the microprocessor, and a display module. The microprocessor is connected to the inductive sensor and the laser ranging sensor, and is used to receive and process signals from the inductive sensor and the laser ranging sensor, calculate the number of hammer blows and the depth of penetration into the soil, and store the calculation results in the data storage module and display them on the display module.

[0032] The embodiment of the present invention further provides a method for automatically calculating the number of hammer blows and the depth of penetration of a pile driver, which is performed using the above system. The method comprises:

[0033] Calculating the number of hammer strikes: After the inductive sensor detects each complete up and down movement of the hammer head (i.e., one hammer strike), a pulse signal is generated. After the data processing unit receives the pulse signal, the count is increased by one, thereby recording the number of hammer strikes in real time;

[0034] Calculation of the depth of the pile: The laser rangefinder measures the height from the bottom of the hammer to the ground in real time. The data processing unit calculates the downward displacement of the hammer based on the continuous height data, thereby determining the depth of the pile in the ground. After each hammering, the data processing unit records the current height value and compares it with the height value after the last hammering, and calculates the cumulative value of the hammer's depth of the pile in one hammering.

[0035] Data storage: The processed hammer blow count and burial depth data are stored in the data storage module for subsequent query and analysis;
