Users can employ graphical development tools of LabVIEW program for CompactRIO, and apply it into various types of embedded control and monitoring applications. CompactRIO is based on the LabVIEW graphical system design platform for development. LabVIEW contains thousands of high-level functions created specifically for industrial measurement and control applications. These powerful tools can easily implement advanced signal processing, frequency analysis, and digital signal processing. For example: the Fast Fourier Transform (FFT), timefrequency analysis and control design and simulation. In the automotive collision avoidance system, we only use the CompactRIO’s analog input, and digital input module.

As we mentioned before, we have prepared a complex measurement system. The developed complex system is improved from that one described in Venglar et al. 2015. It consists of National Instruments CompactRIO devices (NI cRIO) 9067 with up to four input/output (I/O) modules NI 9234, NI cRIO 9053 with up to three I/O modules NI 9234 and two devices NI EtherCAT 9144 with totally up to another two modules NI 9234. The NI 9234 I/O modules are analogue to digital Delta-sigma converters. The modules are suitable for high-accuracy acceleration measurements. Using the proposed system, there is a possibility to totally measure up to 32 places along bridges.

A data acquisition system uses two National Instruments CompactRIO controllers. Controllers operate as a master and slave pair, sampling all recorded signals simultaneously. Two controllers and a time synchronization system were used because RVDs have severe restrictions on load capacitance, making a passive extension of their output cables impossible. CompactRIO system is composed of an FPGA chassis, a real time controller, and a set of reconfigurable I/O modules. The chassis acts as a programmable gateway between the controller and the modules. Various types of modules, like analog input, GPS, synchronization, digital I/O, are available. The real time controller is an industrial computer running a real time operating system. DAQ1 (slave) is located in an outdoor measuring cabinet located near RVDs. It acquires voltage signals coming from RVDs by a single 3-input 400 24-bit ADC module. It also timestamps recorded signals with a time acquired from GPS satellites.
