Design of Intelligent Test System for Cable Logging Instrument Based on LabVIEW
A cable logging instrument intelligent testing system based on LabVIEW is designed to address the com-mon issues of low accuracy,poor reliability,and long development cycles in the measurement and control equipment of traditional logging instruments.The RS-485 communication protocol transfers the calculation and control functions from the motor and solenoid valve control box to the computer,enabling the logging instrument to have intelligent control func-tions such as intelligent reset,intelligent hydraulic,pushing and retracting probe,and reciprocating suction.It can also display the position of the instrument piston,timing,countdown,probe lifting and contraction status diagram,motor speed,current XY diagram,and fluid volume diagram in real time.Experimental tests have shown that the system can stably control the motor and solenoid valve,monitor the voltage,current,and speed of the motor,store data information,and has good robustness.
