To meet the safety requirements for a log flume ride, the technology has to work reliably. An ultrasonic sensor is mounted at the exit of each area. Once a boat goes through the exit, the next boat is able to come through. If the space is occupied, the boats that follow are prevented from entering.
Ultrasonic sensors detect the boats regardless of their shape, color, and occupancy. The ultrasonic sensors are noncontact, so there is no wear to the boat or the sensor. In this application, a UC6000-30GM70S-2E2R2-V15 ultrasonic sensor is used to detect the boats. This type of sensor can withstand extremely harsh environmental conditions and provides consistently reliable signals.
The sensor switching window – the range between the minimum and maximum distance in which the object is detected – is very simple and intuitive to adjust using two potentiometers. Adjustments can be made in everyday operating conditions on the device itself, reliably and specifically for the application. The detection range of the ultrasonic sensor is up to 6 m.
