Abstract
PURPOSE: To improve reliablility, by a method wherein every time the speed designating information is received, the power source of a memory is turned OFF for a short period of time to destroy the information in the memory, and a new speed information is written thereafter.
CONSTITUTION: When a vehicle-mounted member 1a passes a ground member and the frequency of the output signal from an oscillation circuit 1 changes from self- oscillation frequency F1 to a frequency F2 corresponding to a speed designating information B, a relay 4 drops. Because only during the period from the opening of a lifting contact MR2 of the relay 4 to the closing of a dropping contact MR4, the DC power for a memory 5 is shut off, the information stored in the memory 5 is destroyed. On the other hand, for a given period of time after the opening of a lifting contact MR1, the memory 5 is set into the writing mode, a new speed designating information B is stored in the memory 5. Thereby, reliability improves.
