3.3 Dispensers with embedded sensors
Tork dispensers such as Tork Foam Soap Dispenser with Intuition
sensor™ do not need an additional Tork EasyCube sensor. Instead,
they have an additional radio component within the cassette which
forwards information to the DCU via 2.4 GHz radio.
The system runs on the same battery as the dispenser, no additional battery is needed.
3.4 Visitor Registration Unit (VRU)
The VRU counts the number of people going in and out of a room. The
number of visitors can be used as a guideline for when washrooms need to be
cleaned.
The sensor has a flexible measurement direction, just open the two end pieces
and rotate the center unit 90° to change direction. Place one sender and one
receiver at the door frame to the entry of the room. The sensor has a range of
up to 1.7 meters / 5.5 feet. A configurable response time makes the sensor
useful in many different environments and applications.
Each sensor is operated by an embedded battery that will last for 5 years.
3.5 Data Collection Unit (DCU)
The Data Collection Unit, DCU, collects the data from the sensors
(SCUs and VRUs) and sends information to the Tork EasyCube
system. The DCU acts as a communication gateway for all the
sensors that have been paired with it. The unit collects and
processes incoming sensor data.
The DCU has a DC adapter and it has battery backup to ensure
performance during power failure.
The DCU has a built-in GSM/GPRS modem used to connect to Internet. No access to local
physical networks is needed.
Communication between sensors and the DCU is based on SCA proprietary protocol.
3.6 Several DCUs
In order to cover larger areas, several DCUs may be needed. As each DCU has
communication capabilities with the back end server, they can be installed over a large area
with no requirements of in-between communication.
