Problems solved by technology

[0005] However, some positioning devices in the positioning system may be secretly moved by attackers, such as figure 1 Medium6 ,y 6 , d 6 > As shown, the calibrated position parameters of the positioning device are not consistent with the actual position parameters, so that the entire positioning system cannot accurately determine the position represented by the label
As such, precise monitoring of areas of interest may not be possible
In this case, for example, someone who previously did not have access to a computer in the area of ​​interest may now gain access to the computer, creating a security risk, known as a mobile attack

Embodiment Construction

[0027] First, combine figure 2 and 3 , giving a brief description of various terms used in the embodiments of the present invention.

[0028] 1. Space. A space according to an embodiment of the present invention refers to a space in which an object moves. Such as rooms, offices, meeting rooms, etc. figure 2 A schematic diagram of a space 10 is shown, taking a room as an example. It should be understood that the embodiments of the present invention are not limited to figure 2 The room is shown as a quadrilateral, but can be any shape.

[0029] 2. Spatial feature location points. The spatial characteristic position point is a position point for determining the space. For example, in figure 2 In the space 10 shown as an example of a room, the spatial characteristic position points may be room corner position points 11 , 12 and 13 . In principle, any location point in this space can be selected as the spatial feature location point, as long as the space can be determi...

Abstract

The implementation method of the invention provides a system, a method and equipment for determining whether positioning equipment in space is moved or not. The system comprises a label capable of sending ranging signals, positioning equipment and a server, wherein the positioning equipment is configured for acquiring relative coordinates of a position point where the label is positioned relative to the positioning equipment according to the ranging signals of the label; and the server is configured for judging whether the positioning equipment is moved or not according to the relative coordinates, calibration parameters of the positioning equipment and reliable absolute coordinates of the position point in the space. When the system, the method and the equipment are implemented, that whether the positioning equipment is moved or not in real time can be determined accurately and quickly.

Description

technical field [0001] The present invention relates to the field of positioning, in particular to a system, method and device for determining whether a positioning device in space is moved. Background technique [0002] Location information is a basic context used to extract the geographic relationship between the user and the environment to further understand and learn user behavior. The importance and promise of location-aware applications has led to the design and implementation of systems for providing location information, particularly for use in indoor and urban environments. Currently, positioning systems have been developed for precise real-time tracking of people and property in many different applications, which may include environments such as offices, healthcare facilities, coal mines, subways, smart buildings, and restaurants and more. [0003] Currently, positioning systems are usually based on ultrasound or super wideband radio. Their common feature is the...
