  • Page 7 Some errors may occur in certain conditions, like too low supply voltage or too high/low operating temperature. If the operation of the sensor returns to normal and errors do not keep increasing, it is safe to continue using the sensor. Otherwise contact Noptel Oy for further information.

  • Page 9: Operation Modes

    The sensor waits for the target to be in the trigger window and then starts measuring the change of distance to the target in the selected windows. Speeder X1 comprises two integrated laser transmitters with a small angle, allowing measurement of two consecutive overlapping speed profiles from the vehicle.

  • Page 13: Speed Measurements

    Speeder Fig. 1. An example of speed measurement using Speeder X1 laser radar. Speeder X1 has two separate laser beams A and B. The geometry of the measurement is recommended to be >5:1 (please see the Fig. 1): For example, if the sensor is at 5 m height it should be aimed to at least to 25 m distance in order to achieve good speed measurement readings.
  • Page 14 Note 1: Speed pulse rate is in use after detection of a vehicle in speed measurement application (or mode). Speeder X1 is class 1 laser product. Eye-safety standard limits the pulse rate of Speeder X1 to 2000 Hz for pulse trains in short range (Condition 2, target distance less than 2 meters). Laser pulsing exceeding 2000 Hz is allowed only while measured distance is more than 2 meters.
  • Page 15 Note! In this mode the sensor will send the message ”OK” once a minute if the sensor is functional (the message can be disabled by Bit 1 of Control Byte 3, par. 26). ____________________________________________________________________________________ Speeder X1 and X2 Configuration and API Guide Page 15/36...
  • Page 16 ‘QSpeed’. QSpeed is used to generate triggering output for speeding vehicles in real time. Speeder X1 detects the driving direction of the vehicle and compares it to the setting (prm2bit5). In case driving direction is opposite speed value cannot be calculated and QSpeed value is set as wrong direction “QSpeed = WD”.

  • Page 17: Speed Calculation Method

    Speed = NA 4.1.1 Speed calculation method The Speeder X1 is equipped with an advanced dual laser transmitter to allow measurement of two consecutive distance profiles. Both lasers measure the profile from the point where the beam hits onto the vehicle. The measurement starts, when the vehicle arrives into the triggering window of the sensor.
  • Page 18 Fig. 5. Noptel laser radar collects distance measurement data from the area between the sensor and the road surface detecting all passing vehicles. It is possible to acquire exact profile regarding passing vehicle with activated profile measurement.

  • Page 19: Multilane Speed Measurement Mode

    Running “Automatic setting of measurement window” (Chapter 4.3) sets ground distance value in case Speeder is able to measure on to the ground. Furthermore this value can be set manually when the distance is known. ____________________________________________________________________________________ Speeder X1 and X2 Configuration and API Guide Page 19/36...
  • Page 20 Horizontal mode measures speed from the side of the road and can detect vehicles travelling on parallel lanes. Speeder X1 comprises two lasers and it must be installed in correct orientation for intended application. Orientation for horizontal installation is shown in the Fig.

    7 (Speed measurement mode). 4.3 Automatic setting of the measurement window Speeder X1 includes a function that helps the user to set up the triggering window at a correct distance. The function is designed to be used with both Speed measurement modes, vertical measurement (#7) and horizontal measurement (multiple lanes)(#12).
