Description

System and method for finding missing objects

technical field

The invention relates to the technical field of finding missing objects, in particular to a system and method for finding missing objects.

Background technique

In the application of the prior art, the object may move according to its own movement rules, and it is more likely to be affected by external forces to change its movement mode or speed, making it difficult to track or find specific items. In the prior art, it includes the use of identification devices fixedly or removably installed among the movable objects to be tracked. These identification devices have unique identification numbers and send unique identification numbers to adjacent areas with different short-range communication protocols. , and fixed tracking devices are installed in the space where these movable objects may move, and these fixed tracking devices use the suitable short-distance communication protocol used by the identification device to receive the unique identification number issued by the identification device.

Specifically, the device location data of these fixed tracking devices has established a database of fixed tracking devices, which is combined with the geographical database of the space being sought. When a unique identification number is received by one or more tracking devices, a seeking The application can then calculate the position of the movable object associated with the unique identification number. The prior art includes a large space, such as a school, a hospital or a train station, in which a tracking device is fixedly installed, and the geographic locations of all fixed tracking devices installed in the space are represented by a three-dimensional Cartesian coordinate system ) or otherwise stored in digital form. That is, the location can be found out according to the tracking device in the database. Therefore, in the prior art, one or more tracking devices receive a unique identification number to calculate the position of the movable object associated with the unique identification number.

In a preferred prior art, the German patent application DE10357023A1 (application date is December 3, 2003, hereinafter referred to as D1) discloses an invention of tracking and finding a mobile device, wherein the identification device is installed on the mobile and On the object being sought, the identification device sends out its unique identification number to the adjacent space by means of short-distance effective communication. One or more tracking devices may be fixedly mounted within the active seeking space, or may be movable to receive unique identification numbers while moving within the active seeking space. Fixed-mounted tracking devices already record their location by default, represented by three-dimensional Cartesian coordinates or other numbers. The mobile tracking device further has built-in functionality to calculate its location. That is, when the mobile tracking device receives the unique identification number, it also calculates the current location of the mobile tracking device.

However, this existing technology limits the convenience of starting the search. In some scenarios where the flow of people, the flow of goods, and the speed change greatly over time, the fixed base station is to pre-design the installation location and install it, record the fixed Cartesian coordinates and, Establish a database of tracking devices (fixed base stations), etc. This design needs to deal with finding lost items under the environment of the highest flow of people, logistics and flow speed, which will become difficult.

For example, in a multimodal transportation station, most people flow from the residential area to the commercial area in the morning to go to work, and most of the people flow from the commercial area to the residential area at night. This has different quantity and power requirements for the installation and use of the fixed base station of the tracking device when the object is to be found in the whole station. When it is necessary to look for a certain object, such as handbags, luggage carts, wheelchairs, etc., as well as some special identifiers attached to individuals, these objects are most likely to follow the flow of people and stop at one point, that is, at the flow of the most people and logistics. Stop in the process, to search and rely on the fixed base station tracking device that has been fixedly installed, it may be blocked by dense mobile flow of people and objects for short-distance communication. In this way, it will be difficult to find missing objects in the environment of high flow of people, logistics and flow speed.

In summary, there are obviously inconveniences and defects in the actual use of the prior art, so it is necessary to improve it.
