Abstract
Apparatus for tracking vehicle position relative to a starting point and for providing continual display of vehicle position. The apparatus includes a gyroscope and odometer for generating respective direction and distance electrical signals which are then converted to digital signals for control of a video monitor. An area map overlay may be included on the face of the monitor; and, the position indication signals may be continually transmitted to a selected central location in order to provide reference indication as to a particular vehicle.
Claims14
A system for maintaining position surveillance of moving vehicles, comprising:
- means generating a pulse output proportional to distance traveled by said vehicle;
- counter means receiving said pulse output to generate periodically a distance digital word data output;
- means generating an azimuth digital word data output indicating the degree of vehicle heading;
- microcomputer means receiving input of said distance digital word and said azimuth digital word data outputs to provide output of vector digital data, said microcomputer means including a central processing unit receiving selective input of said distance and azimuth digital word data to generate output of said vector digital word data, and a read only memory means having a selected, resident program that is connected to control the logic processing of said central processing unit;
- and
- video monitor means receiving said vector digital word data output to continually display relative vehicle position.
