4.2 Embedded software
4.2.1 Overview
The Intelligent Vibration Analysis Sensor (IVAS) is a measurement device developed for condition and process monitoring.
For this, it contains two acceleration sensors. One accelerometer has a bandwidth of 20 kHz for detecting structure-borne
sound and the second accelerometer measures vibrations in three dimensions with a high sensitivity and a bandwidth of up
to 3 kHz.
The IVAS Ethernet variant is an IP network device supplied via Power-over-Ethernet (PoE). Figure 6 shows an exemplary
setup, where three IVAS devices are connected to a Laptop through a PoE-enabled network switch.

4.2.3 Startup
After being powered up, IVAS enters the default data streaming application, which transmits sensor measurements over the
Ethernet network as configured. When accessed via HTTP (e.g. from a Web browser), IVAS will perform a reset and boot into
the bootloader application for configuration and firmware updates.
The following sections describe both operation modes
4.2.4 Data streaming application
The data streaming application implements sending the measurement data of the sensors integrated in the IVAS device to
the network. The bootloader per default starts the streaming application after power-up.
Initially, when DHCP is enabled, the IVAS node will try to obtain an IP configuration from a DHCP server. If this is not success-
ful after 8 seconds, the static configuration is applied.
