Abstract

PURPOSE:To eliminate unnecessary operation and to prolong the life of a laser radar device by detecting the running state of a car and connecting a power supply, and putting the laser radar equipment in operation only during the car is running. CONSTITUTION:The laser radar equipment 1 is connected to the power source 3 through a control switch 2, which is brought under on-off control based upon the control signal from a run detecting circuit 4. The circuit 4 detects a car running state and generates the control signal for operating the switch 2. The device 1 is therefore put in operation only during the car is running to eliminate unnecessary operation while the vehicle is stopping.

Discharged when on. When the capacitor 45 is charged, the capacitor 48 is also charged at the same time, and the capacitor 48 is discharged at a much slower rate than the capacitor 45 via the resistor 49 and the heath and emitter of the transistor 50. The amount of charge is proportional to the number of times the reed switch 41 is turned on and off, that is, the vehicle speed. Therefore, when the charge type 6:j of the capacitor 4 reaches a predetermined value, that is, when the vehicle speed reaches a predetermined vehicle speed, for example, 4 K m /H, the transistor 50 is made conductive. When the transistor 50 becomes conductive, the coil 21 of the relay 2 is energized, and the
