Trip Detection

Here you define parameters to detect trips and stays. Trip is a period of time when a unit was moving. Stay is a period of time when a unit was motionless.

Depending on the equipment installed and the parameters set on this tab the reports on movement intervals (trips) and idles (stops, parkings) can be rather different.

Movement Detection

There are five main methods of how movement intervals are detected:

  1. GPS speed
    This method is universal and can be applied to any device type and configuration. The parameters of this method are described below.

  2. GPS coordinates
    This method is universal as well. The movement is detected if the coordinates in two successive messages are different. The fact is that some equipment types do not provide speed parameter in messages. In this case, movement can be detected by coordinated without installing additional equipment.

  3. Engine ignition sensor
    This method is available for units having ignition sensor. If so, the trip begins when the sensor is switched on and ends when the sensor is switched off. Besides, GPS correction can be added.

  4. Mileage sensor
    This method can be used for units which have a mileage sensor. The sensor transmits the absolute mileage. The beginning of a trip is detected when the mileage value increases, and the end is detected when mileage value stops to grow. Here GPS additional correction is also available.

  5. Relative odometer
    shows what distance was rolled from the previous message. Note that 'Minimal movement speed' parameter must be '0'.

In all cases you can additionally use GPS correction to receive more precise data in reports.

GPS Correction

To activate GPS correction of data put a check mark near Allow GPS correction.

  • Minimum satellites count
    It means how many satellites are needed to consider data to be valid. Recommended number is three and more, but two are enough for some types of equipment.
  • Minimum moving speed
    Specify which speed should be considered as the beginning of the motion. This is needed to exclude adjustment of data. The equipment can locate coordinates with an accuracy of ±10, so a speed of 1-2 km/h can be assigned to the unit which is not moving in fact. To exclude such cases from the trips, set this parameter.
  • Minimum perking time
    Set time in seconds how long the unit should be immovable to register this as a parking. This option allows excluding stops in traffic jams, at a lights or at an intersections.
  • Maximum distance between messages
    Indicate the distance in meters to exclude adjustment of data. It means if according to the message received the unit moved relatively to the previous message greater distance, then the previous trip is over and a new trip begins.
  • Minimum trip time
    This is also to exclude cases of adjustment of data. For example, the unit on the parking moved from one place to another, and movement during 40 seconds was detected. To exclude such cases from trips, set minimum trip time (in seconds).
  • Minimum trip distance
    This is a similar parameter. But here you indicate the minimum trip distance (in meters). For example, the car is parked, and the device sends coordinated according to which the car has moved a couple of meters. It can happen because of permissible equipment error. In order to not count such situation as movement, indicate how far the unit have to move to consider it as the start of a trip.
