    ˽ SmartSensor V Package ˽ Selecting a Mounting Location The Wavetronix SmartSensor V utilizes patented Digital Wave Radar™ technology to detect lane occupancy, traffic volume and average speed in up to eight lanes of traffic simultane- ously. Classified as frequency modulated continuous wave (FMCW) radar, SmartSensor V collects data using a 10.525 GHz (X-band) operating radio frequency.

  • Page 22 Figure 2.2 – Surge Protected Terminal Connections (Top) Follow the diagram above to wire into the UNPROTECTED side of the Click 200. Note The predecessor to the SmartSensor V, the 105, used the 9-conductor cable. For information on this cable, see Appendix B. Grounding The Click 200 device in the main traffic cabinet should be grounded.
  • Page 23 CHAPTER 2 • CONNECTING POWER AND SURGE PROTECTION The SmartSensor V itself also needs to be grounded via its grounding lug. Connect a grounding wire to the grounding lug on the bottom of the sensor (see Figure 2.3). Figure 2.3 – Grounding Lug on SmartSensor V Connect the other end of the grounding wire to the earth ground for the pole that the sensor is mounted on.

  • Page 25 CHAPTER 2 • CONNECTING POWER AND SURGE PROTECTION Wiring AC Surge Protection To include AC surge protection in your installation (see Figure 2.4): Mount the Click 230 onto the DIN rail. Connect the line conductor (hot) from the Click 210 to terminal 5 on the IN side of the Click 230.
  • Page 26 CHAPTER 2 • CONNECTING POWER AND SURGE PROTECTION Note The NC screw terminal is not connected internally. Connecting a wire to a no con- nect (NC) terminal simply gives it a convenient termination point. Wiring DC Power Out of the Click 201/202 Connect a +DC conductor (usually a red wire) to the + screw terminal on the bottom of the Click 201/202 (see Figure 2.6).
  • Page 27 CHAPTER 2 • CONNECTING POWER AND SURGE PROTECTION Connecting Power through the T-bus The Click 200 is mounted on the T-bus, which consists of a number of small modules that pass power and communications to any device mounted on them. For this reason, one way to get power to a Click 200 is to provide power to the T-bus via the 5-position screw termi- nal.

    The question then becomes what communication options will best suit the installation. Wavetronix Click products facilitate a wide variety of additional wired and wireless com- munication options. Contact a Wavetronix-authorized technical representative to find out which options are best suited for your application.

  • Page 58: Lane Setup

    Lane Setup In this chapter ˽ Lane Configuration – Automatic ˽ Lane Configuration – Manual ˽ Verifying Lane Configuration Setting up lanes is simple in SmartSensor Manager because the software will do it for you with the click of a button. Additionally, if SmartSensor Manager is unable to correctly con- figure due to barriers, obstacles or irregular lanes, you can use the Manual Configuration mode to adjust.
  • Page 59 CHAPTER 6 • LANE SETUP Click the Restart button at the lower right. Confirm the configuration restart by clicking Yes in the box that appears (see Figure 6.1). SmartSensor Manager will now automatically begin detecting and configuring lanes, and the screen will show a visual depiction of the lanes and vehicle detections in real time.
  • Page 60 CHAPTER 6 • LANE SETUP Click the Restart button to apply the range blinders. When the range blinders are ap- plied, they will turn from a red color to a dark khaki color. To cancel and use the default ranges, or to start over, or click the Range Blinders button again. After the lanes are detected and configured correctly, save the configuration by click- ing the Finished button.
  • Page 61 CHAPTER 6 • LANE SETUP Note The default starting point of 5 is also the largest starting point allowed. If you enter a value larger than 5 the default starting point of 5 will be used. If you are managing the gain, you should generally change the starting point to a 3 or 4.
  • Page 62 CHAPTER 6 • LANE SETUP Lane Center Lane Divider Shoulder Figure 6.3 – Adjusting Lanes Paint and Remove Lines The Paint Lines button allows you to add new lanes by inserting lane dividers in paved (black) areas. SmartSensor Manager allows a maximum of eight lanes. Again, the cursor will change from an arrow to a hand when it is positioned directly over a location where it is possible to paint a lane divider.
  • Page 63 CHAPTER 6 • LANE SETUP Construct and Remove Barriers Constructing a barrier or median is essentially the act of dividing a single road into two separate roads. SmartSensor Manager defines a barrier or median as two adjacent shoulder lines or two shoulder lines with only background (khaki-colored) areas in between them. To construct a barrier or median, click on the Construct Barriers button and move the cur- sor to the paved area where you want to insert the barrier.
  • Page 64 CHAPTER 6 • LANE SETUP Edit Lane Names By default, the SmartSensor V identifies the lanes it configures as lane 1 up to lane 8, where lane 1 is located closest to the sensor. However, you may wish to assign lane numbers differ- ently with the Edit Lane Names window (see Figure 6.5).
  • Page 65 Lane Configuration page by clicking on the Finished button located at the bottom right of the screen. A window will appear indicating that the changes are being saved to the SmartSensor V. After the changes have been saved, SmartSensor Manager will automatically change from Lane Configuration to Traffic (Event) Data View mode so that you can verify lane configu- ration.
  • Page 66 Traffic (Event) Data In Event mode, this screen allows you to verify the SmartSensor V’s configuration by com- paring the traffic on the road to event information shown in the window (see Figure 6.8). In order to keep a record of your verification results, the event data can also be saved to a log file while you remain on this screen.
  • Page 67 CHAPTER 6 • LANE SETUP Note A status bar below the Traffic View window indicates whether you are in Event mode or Actuation mode. By default, Traffic View launches in Event mode. In Event mode, the vehicles (represented by the blue rectangles) appear after having passed through the radar detection zone. The four icons located at the bottom of the screen are active in this mode.
  • Page 68 CHAPTER 6 • LANE SETUP Figure 6.10 – Event Log The event log file breaks down each event and reports back the event Timestamp, Lane Name, Duration, Event Speed, Class, and Count. The timestamp, which is formatted using the local time zone settings on your computer in hours, minutes, seconds and milliseconds, is the time the vehicle entered the detection zone.
