[0031] The meaning of certain terms used in context is explained in more detail below:
[0032] - Time window: this term means the period of time during which objects (groups) logically related to each other should pass the identification point. The time window can be set individually for each group, or alternatively all groups can use the same specific time window. The time window begins, for example, when a recognition point or tracking center recognizes the first of certain objects that are logically associated with each other. Alternatively, the time period of the time window is always calculated from zero when any of the specific objects that are logically associated with each other are identified.
[0033] - Feedback action: This term means a measure that is executed if one or more objects logically associated with each other do not pass the identification point within a predefined time window. Feedback actions can be, for example, one or more of the following measures...

Abstract
The object of the invention is a method for tracking objects in a tracking system. In the method at least two different objects (206, 310, 410, 510) are provided with a transmitter (204, 308, 408, 512), in each of which is individualized identifier data and the objects (206, 310, 410, 510) are logically connected to each other by connecting the identifier data of the transmitters (204, 308, 408, 512) to each other. In the method, further, the identifier data of the transmitters (204, 308, 408, 512) of the objects (206, 310, 410, 510) that are logically connected to each other are recorded in memory (212, 306, 408, 514), the transmitter (106, 208, 306) of the object (206, 310, 410, 510) is detected with the receiver (104, 204, 304) of the identification point (200, 300, 400, 500) when the object (206, 310, 410, 510) comes close to the identification point (200, 300, 400, 500), it is determined on the basis of the data contained in memory (212, 306, 408, 514) whether at least two objects (206, 310, 410, 510) that are logically connected to each other have traveled past the identification point (200, 300, 400, 500) inside the pre-defined time window; and one or more pre-defined feedback actions are performed when at least two of the aforementioned objects (206, 310, 410, 510) that are logically connected to each other have not traveled past the identification point (200, 300, 400, 500) inside the pre-defined time window.
Description
technical field [0001] The present invention relates to tracking of objects. More specifically, the object of the present invention relates to a method and a system for tracking objects in a tracking system. Background technique [0002] As a result of the wireless transmission of information, people and goods can be tracked and monitored in many different ways today. A mobile phone can be located with a certain degree of accuracy based on the signals it sends. On the other hand, if a dedicated locator device such as a GPS locator is in use, positioning can be performed very accurately. [0003] Tracking of objects and goods is usually performed in a closed system within a building, for example in a library, in a shop, or in different warehouses. Smaller size transmitters or transmitter-receivers can be attached to books, boxes, or other objects. When a book, box or other object affixed with a transmitter is transported past a particular identification point, the identif...
