Title:
ROAD GRADIENT DETECTING AND WARNING DEVICE
Document Type and Number:
Japanese Patent JPH1114351
Kind Code:
A
Abstract:
PROBLEM TO BE SOLVED: To prevent back running of a vehicle for paving by automatically detecting the gradient of a road, and giving a warning when the gradient is a designated value or more. SOLUTION: A circuit part 20 includes a gradient detecting part 30 for detecting that the road has a gradient of a designated value or more when a detection signal of a photoelecic sensor 15 is input more than designated time, and outputting a warning signal, a warning generating part 26 to which the warning signal is input to give a warning, a device part 10, and a charging part 35 for supplying power to the circuit part 20. In the gradient detecting part 30, a detection signal from the photoelectric sensor 15 is input, the gradient of the road is detected by a detecting part 32, the input time of a detection signal of the detecting part 32 is measured by a timer 34, and when the input time is above designated time, a warning signal is output to the warning signal generating part 25. In the warning generating part 25, a desired voice signal is input through a voice part 26 having ROM where a desired voice signal is recorded, a warning is generated by voice from a speaker 27, and the signal is also input to a warning lamp 66 to give a warning by means of light.
