Problems solved by technology

However, the cost of using multiple detectors is high
[0004] Therefore, the disadvantage of existing sensing systems is that a large number of sensors are necessary, which leads to high production costs
The sensor needs to interface with multiple detectors, which further increases the production cost of existing systems
Finally, the larger number of required scanning steps slows down localization

Embodiment Construction

[0041] Figure 2A shows that it is divided into 16 scanning positions P11-P44 (the general formula is P 列-行 ) game board 1 on which objects 2 with specific properties can be placed. Scanning positions P11-P44 are arranged in a matrix of four rows and four columns. The panel 1 comprises a sensing system according to the invention for sensing predetermined physical properties. In this embodiment, the sensing system is adapted to be used as a system for locating an object 2 having predetermined physical properties within one of the scanning positions P11-P44. For example, the object 2 may be configured as a tag with a built-in RFID tag 2a. Each scanning position is identified by a unique binary position code BC (see Figure 2B), as explained below. The system for locating an object 2 comprises a plurality of sensors A1-A5, which in this embodiment are configured as antennas for reading an RFID tag 2a. Strictly speaking, the sensors A1-A5 are configured as loop antennas with sca...

Abstract

A system for sensing a physical property allocated to scanning positions (Pl-P5, P11-P44, Pijk) comprises sensors (A1-A5, B) adapted to sense the physical property within sensing regions (AR1-AR5, BR1-BR2, C1-C3, D1-D3, E1-E3, F1-F4, G1-G3, H1-H4), wherein the sensing regions (AR1-AR5, BR1-BR2, C1-C3, D1-D3, E1-E3, F1-F4, G1-G3, H1-H4) are arranged such that each of them sweeps at least one scanning position (P1-P5, P11-P44, Pijk), and sensing regions (AR1-AR5, BR1-BR2, C1-C3, D1-D3, E1-E3, F1-F4, G1-G3, H1-H4) are superposed on one another at least in one scanning position (P1 -P5, P11- P44, Pijk), so that each scanning position is swept by a unique pattern of sensing regions (AR1-AR5, BR1-BR2, C1-C3, D1-D3, E1-E3, F1-F4, G1-G3, H1-H4), wherein the following condition is fulfilled: log2(n) = i < X N1 / x with i ... number of sensing regions n ... number of scanning positions x ... number of spatial dimensions in which the arrangement of scanning positions extend.

Description

technical field [0001] The present invention relates to a system for sensing physical properties assigned to scan locations, the system comprising sensors for sensing physical properties within sensing areas arranged such that each said area is swept across at least one scan The sensing areas overlap each other at least at one scanning position such that each scanning position is swept by a pattern of unique sensing areas. Background technique [0002] Sensing systems comprising sensors having sensing regions arranged in a row-column configuration are known. For example, an object with a built-in RFID tag can be easily located at a specific location on a shelf or at a specific end of a machine delivery system that is scanned by antennas arranged in rows. Each specific location is defined by the intersection of a row of antennas and a column of antennas. This known principle is illustrated in Figure 1A, where a game board 1 is shown with 16 scanning positions Pij arranged i...
