1. A system for a movable object with a first monitoring device, said first monitoring device comprising:
- a first receiver for a radio based positioning system;
a first control unit for generating first device status datasets, wherein said first device status datasets comprise positional data derived from a signal of said first receiver;
a first radio circuit for broadcasting said first device status datasets to other monitoring devices; and
an output device adapted to issue proximity warnings,wherein said first control unit is structured for generating said proximity warnings in dependence of the signal from said first receiver and of device status datasets received from other devices;
wherein said movable object comprises at least one second monitoring device, wherein said at least one second monitoring device comprises;
a second receiver for the radio based positioning system,a second control unit for generating second device status datasets, wherein said second device status datasets comprise positional data derived from a signal of said second receiver, anda second radio circuit for broadcasting said second device status datasets to other monitoring devices; and
wherein said first monitoring device and said at least one second monitoring device are arranged on said same movable object at a distance from each other for determining an orientation of said same movable object.

Abstract
Vehicles and other objects in a surface mine are equipped with monitoring devices that communicate by radio in order to detect the risk of collisions. The devices are equipped with GNSS-receivers. At least one of the objects has two devices mounted to it. Each of the two devices determines its position independently, which in turn allows determining not only the position, but also the orientation, of the object.

11. A method for generating proximity warnings on an area by means of a monitoring apparatus comprising a plurality of monitoring devices, wherein at least some of said monitoring devices are installed on objects operating in said area, wherein at least part of said monitoring devices comprise a receiver for a radio based positioning system and a radio circuit, said method comprising:
-
mounting, to a same at least one first movable object in said area, a first and a second monitoring device at a distance from each other for determining an orientation of said same at least one first movable object; generating, by means of said first monitoring device, a first device status dataset depending on a position of said first monitoring device, and emitting said first device status dataset through the radio circuit of said first monitoring device; and generating, by means of said second monitoring device, a second device status dataset derived from a position of said second monitoring device, and emitting said second device status dataset through the radio circuit of said second monitoring device. - View Dependent Claims (12, 13, 14, 15, 16, 17, 18)

19. A method for generating proximity warnings in an area by means of a monitoring apparatus comprising a plurality of monitoring devices, wherein at least some of said monitoring devices are installed on at least a first and a second movable object operating in said area, wherein at least part of said monitoring devices comprise a receiver for a radio based positioning system and a radio circuit, said method comprising:
-
receiving, on said second movable object, device status datasets from said first movable object, wherein said device status datasets of said first movable object are generated by a first and a second monitoring device mounted at a distance from each other on said same first movable object for determining an orientation of said same first movable object; and generating, by the monitoring device of the second movable object, proximity warnings by taking an orientation and dimension of said same first movable object into account. - View Dependent Claims (20)
