Geofencing
Virtual map boundaries trigger actions such as speed limits, warnings or access restrictions when a vehicle enters, leaves or remains in an area.
Definition
Geofencing compares live vehicle positions with mapped zones and triggers predefined actions. Industrial applications include speed reduction near pedestrians, corners, slopes and intersections, restricted-area control, access logging and operation rules. Position accuracy is central to effectiveness, making indoor deployment more demanding than broad outdoor zones.
Positioning Determines Feasibility
Satellite positioning can suit large outdoor zones. Indoors, UWB can offer finer accuracy but needs anchors; Bluetooth or Wi-Fi provide cheaper, coarser positioning. Inertial and vehicle-motion estimates bridge brief gaps but accumulate error. Match positioning investment to the risk and required zone size.
Accuracy and Boundary Design
Metre-scale position noise near a tight boundary can cause false entry and sudden slowing. Shrinking the zone can instead delay protection. Buffer areas, different entry and exit thresholds, confirmation across successive positions and smooth speed transitions help avoid oscillation and load disturbance.
Typical Applications
Use zones for speed control, vehicle or operator access rights, task-location verification and risk-exposure records. Lift state can support rules against elevated-load travel in selected areas. Begin with a small set of valuable rules so operators understand the response.
Rule-Design Problems
Overly low speeds, oversized zones, no controlled exceptions and stale boundaries create friction and bypass attempts. Safety teams, production staff and operators should jointly define rules. Revisit boundaries and thresholds using operating data and whenever layouts change.
Fleet Platform Integration
Entry records, speed interventions and attempted violations reveal risky places and times. Use them to improve traffic routes, layouts and training rather than only record compliance. Version zone configurations with change times and reasons to support incident investigation and effectiveness reviews.
Frequently Asked Questions
How does geofencing work without indoor satellite reception?
Use UWB, Bluetooth, Wi-Fi or combined inertial and vehicle estimates, selecting accuracy and infrastructure by zone risk and size.
Why does a truck slow down outside the marked zone?
Position noise can falsely cross a boundary. Appropriate buffers, entry/exit hysteresis, repeated-position confirmation and smooth control help, provided the positioning accuracy suits the zone.
