Real-time location information system using multiple positioning technologies

摘要

Systems, methods and computer program products for tracking objects in an area of interest are described. According to an embodiment, an object is tracked as follows. First position information relating to the object is received from a first sensor and translated to a coordinate system of a map. The object is displayed on the map in accordance with the translated first position information. Second position information relating to the object is received from a second sensor, where the second sensor is based on a second positioning technology different from the first positioning technology. The second position information is translated to the coordinate system of the map, and the object is displayed on the map in accordance with the translated second position information. In an embodiment, other information relating to the object is also received from sensors.

主权项

1. A computer program product including a non-transitory computer-readable medium having instructions stored thereon that, if executed by a processing device, cause the processing device to perform operations comprising:
receiving a first notification of a first event occurring at a first sensor, the first sensor being one of a plurality of different sensors positioned throughout a physical area and fixed at a first geographical location of the physical area; determining a user is at the fixed first geographical location of the first sensor based on the received first notification; receiving information from an environmental sensor, the environmental sensor being one of the plurality of different sensors positioned throughout the physical area and fixed at a second geographical location of the physical area, the second geographical location being different from the first geographical location, wherein the information includes a current environmental characteristic of the physical area and the second geographical location; translating the first geographical location and the second geographical location to a coordinate system of a map; displaying an object representing the user on the map in accordance with the translated first geographical location and relative to the translated second geographical location; and displaying, on the map, at the first geographical location and proximate to the object representing the user on the map, information corresponding to the current environmental characteristic of the physical area.
