AI summary
A method for monitoring the working environment of a mobile device is proposed, wherein the working environment comprises a work zone and at least one protection zone, and the mobile device is located in the work zone during its normal operation. The method comprises: inputting, by a user, a plurality of convex polytopes into the monitoring device, the convex polytopes corresponding to zones in which the mobile device is located during normal operation; determining a convex polytope envelope by the monitoring device, wherein the convex polytope envelope completely encompasses the plurality of convex polytopes; and determining the at least one protection zone by calculating the difference between the convex polytope envelope and the input from the monitoring device. Monitoring the position of the mobile device is simplified because the work zone can be modeled autonomously.
