Improved Backup Alarm Technology for Mobile Mining Equipment.

PB86229747

Publication Date	1986
Personal Author	Johnson, G. A.; Griffin, R. E.; Laage, L. W.
Page Count	28
Abstract	Despite the use of warning alarms to alert miners to the backward movement of large mining equipment, miners still are injured to frequently in backup accidents. Currently approved backup alarm technology consists of continuous sounding alarm systems. New technology has developed a warning system that initiates an alarm only if there is an object close behind the vehicle. The Bureau of Mines report describes the general characteristics of infrared (IR) light, ultrasonic wave, and Doppler radar technology as used for backup alarms, and reviews the testing of the most promising detection devices.
