System for automatically measuring piling results in a piling operation

A system for automatically measuring piling results of a piling operation by a piling machine operated by an operator comprising:

• a pile numbering unit for numbering a pile;
• an operational date setting unit for setting a date when the piling operation is carried out;
• a reference sinking amount setting unit for setting a reference sinking amount of the pile;
• an average times of hammering setting unit for setting average times of hammering by a piling machine;
• a stop signal generating unit for generating a stop signal;
• a start signal generating unit for generating a start signal;
• a pile sinking displacement measuring unit for measuring a sinking displacement amount of the pile, said unit being operatively coupled with the pile;
• a pile perpendicularity detecting unit for detecting perpendicularity of the pile;
• a hammering sound detecting unit for detecting a hammering sound;
• a central processing unit (CPU) electrically connected to and being supplied with electrical signals from said pile numbering unit, said operational date setting unit, said reference sinking amount setting unit, said average times of hammering setting unit, said stop signal generating unit, said start signal generating unit, said pile sinking displacement measuring unit, said pile perpendicularity detecting unit, and said hammering sound detecting unit, for processing said electrical signals, and controlling said system;
• a data printer for printing operation data upon receiving data signals from the CPU;
• a signal display for displaying respective visual signals such as a waiting signal, a working signal and a stop signal upon receiving a control signal from the CPU;
• an informing speaker for informing the operator of information upon receiving an information signal from the CPU;
• a pile perpendicularity display for displaying perpendicularity of the pile upon receiving a perpendicularity signal from the CPU;
• and
• a measuring arm for mounting said pile sinking displacement measuring unit and said pile perpendicularity detecting unit.
