Sensys FLEX Control VDS
The Sensys Networks FlexControl is a compact module that controls the components of the Sensys Networks Wireless Vehicle Detection System (VDS). It maintains two-way wireless links to the sensors and repeaters, establishes overall time synchronization, transmits configuration commands and message acknowledgements, and receives and processes data from the sensors. The FlexControl then relays the sensor detection data to a roadside traffic controller or remote server traffic management system. The FlexControl provides equivalent functionality as the Access Point Controller Card (APCC) except for the internal contact closures.
The FlexControl uses an ARM-based Linux computer to provide layers of processing and networking. Processing includes analytics for traffic data, traffic signal control, specialized control applications (e.g., wrong way ramp detection and speed enforcement), and system performance and diagnostic reports. Networking includes complete SNP† functions, SNP security and proxying, as well as Linux-based IP, VPN, secure access (ssh), and secure web server (https) capabilities. Custom add-ons can be developed by qualified customers for their own remote applications.
The FlexControl includes dual Radio ports (SPP-0 and SPP-1) and an expansion (EX) port. The EX port connects to the EX card or the FlexConnect module to relay detection events to a traffic controller. The FlexControl has two USB 2.0 full speed host ports, one 10/100Base-T Ethernet port, and one USB device port. The FlexControl is powered by a 9-28 VDC source via a barrel connector or a pluggable terminal block connector. The FlexControl includes a DIN mount and a bracket mount kit for installation in a traffic cabinet. The FlexControl module is configured by TrafficDOT over the Ethernet port.
