Research of Running State Monitoring and Over-speed Protection System of Endless-rope Continuous Towing Vehicle

In view of problems existed in current running state monitoring and over-speed protection device of endless-rope continuous towing vehicle, the paper proposed a design scheme of running state monitoring and over-speed protection system of endless-rope continuous towing vehicle. The system uses structure of upper-lower computer. The upper computer based on LabVIEW realizes functions of parameter setting, data storage, running state display and remote control. The lower computer firstly collects signals of running speed and pressure of accumulator of braking system and brake oil-cylinder, then analyzes, processes and judges the signals with some algorithm by use of single-chip microcomputer. The lower computer can output corresponding fault signal if the vehicle has faults of over-speed, under voltage and broken rope. The upper computer communicates with the lower computer with wireless mode. The actual application showed that the system can realize effective monitoring for running state and correct judgment for over-speed fault of the vehicle.
