RCV Sonar ranging system
General information
This is a sonar ranging system that uses ultrasonic sensors to measure dissonance to objects on up
to 20 locations and then communicates the data via CAN BUS. It is currently designed to use
MAXBOTIX sonar rangers that send an analogue voltage as their data to the micro controllers on
the main PCB, but it can also be redesigned from the EAGLE CAD files and built to use sensors
with other means of communication (digital) using the same idea and power supply design.
It is powered by the 24V rail on the car.
Requirements:
- OS: Windows 7 or newer, 64bit
- AVR Studio (to program the AVR controllers and change CANBUS settings)
- CAN KING for setting up and debugging
Elements
Here we will discuss the general architecture of the system.
Main PCB (Green) – it is the “motherboard” of the system, providing power and I/O to the
different replaceable computing components (AVR CAN microcontrollers). It is custom designed
