SELFFMONITORING AND SEQUENCE CONTROLING SYSTEM FOR TRACTOR

摘要

For a vehicle powered by accumulators an automatic control and sequencing system ensures that the power is applied in conditions of safety. The system comprises several bus bars with a control circuit containing logic gates. The accumulators of a vehicle are connected through a start stop switch to a primary bus bar which excites an information transmitter. A principal bus bar supplies several motors for steering and traction. A secondary bus bar operated by a switch in series with the start stop switch activates several control circuits. A control and sequencing unit produces validation signals from several input signals to operate a control unit, for the motors.
