The Design of Telemeter for Motor Move Backward

The function confirmation,meterage distance principle,design means and technique implementation of telemeter which is for motor move backward ate introduced.The method of signal processing of the measured distance between the motor and the obstruction,and method to effectively measure and real time display,the distance between the motor and the obstruction are discussed.All of the different alarm types are prescribed.They are signifi,cant for correlative kind designs of measure system.
