2. Introduction
2.1. Purpose of the CAS system
The main task for SAFEmine QC2xx series products is to support the operator while he scans the
space ahead and around the vehicle with his own eyes, cameras and other aids. SAFEmine products
are simple to use and are designed not to distract the operator from operating the vehicle.
2.2. The Collision Avoidance Principle
The SAFEmine collision avoidance device is equipped with a GPS receiver, additional sensors and
an RF transceiver. The GPS receiver will provide the unit with a position, speed and heading. This
information is continuously broadcasted over the air thanks to the RF transmitter/ receiver.
A vehicle will receive the information from all the surrounding vehicles while transmitting its own
information. Based on this information, sophisticated SAFEmine algorithms will determine a collision
risk level and indicate it to the operator of the vehicle via the display.
As every vehicle has different dynamics and every mine has different rules, SAFEmine provides a list
of features and configuration possibilities which can custom tailored to the needs of our customers.
The display, either remote (QC230/QC24x/QC250) or integrated (QC235), warns the driver of
potential threats, gives the status of the device, and allows user interaction with the Square button.
Additionally to the LED indicators it also has a buzzer, a ambient light sensor and a noise sensor.
The image above shows a display while the device is operating in a vehicle, traveling forward
(‘Reverse LED’ is OFF) and a vehicle (equipped with another SAFEmine device) is detected. The led
on in the 12 o’clock position indicates the presence of a vehicle in front. Several colors and sounds
indicate different threat levels. Depending on the distance to other vehicles and on the configuration
parameters an alarm might be audible. The center compass displays direction and distance of
vehicles within the RF transmitter / receiver range but it also serves to display error codes in the case
a system failure was detected.
The LEDs on the left side of the display show the status of the SAFEmine device. They indicate if the
device has enough power, has acceptable GPS reception or is traveling backwards as well as other
information about the system.
Depending on the configuration, pushing the square button on the right of the display can trigger
three functions:
1) Flag special events in the unit’s log-file: for example an incident or a situation where the user
believes the SAFEmine device didn’t perform as expected.
2) Announce the ID of nearby vehicles: If the ‘Voice Option’ is enabled, surrounding vehicles
are announced.
3) Acknowledge an alarm: The operator can stop the warning sound for example when being
towed by another vehicle.
