Multi-point antenna transceiving induction position distinguishing plate

Abstract

The invention discloses a multi-point antenna transceiving induction position distinguishing plate. The multi-point antenna transceiving induction position distinguishing plate comprises: a panel body; a plurality of signal receiving antenna units which are arranged in parallel and are distributed on the panel body; a plurality of signal transmitting antenna units which are arranged in parallel and distributed on the panel body, wherein the signal transmitting antenna units and the signal receiving antenna units are mutually staggered, induction points are formed at the staggered positions, and at each induction point, the signal receiving antenna units can continuously receive antenna signals with fixed sizes, which are transmitted by the signal transmitting antenna units; and a triggering device whch is provided with at least one triggering piece, wherein the triggering piece is made of a material capable of weakening or amplifying the antenna signal, and when the triggering piece isclose to the induction point, the antenna signal at the induction point is changed, and the position of the triggering piece corresponding to the panel body can be judged through the change of the signal.

Description

technical field [0001] The present invention relates to a multi-point antenna transceiver induction positioning board. Specifically, it relates to a sensor that utilizes a plurality of wireless transceiver antennas in a staggered distribution, and then at the staggered points, changes in local antenna signals to achieve position determination. board application. Background technique [0002] With the development of electronic technology, the input types of the human-machine interface are also increasing. In order to pursue intuitive operation and improve relative convenience, the touch input method is widely used in various types of electronic products. Generally speaking, the methods of touch identification can be divided into electromagnetic touch identification, resistive touch identification, capacitive touch identification and so on. [0003] Among them, the electromagnetic touch position identification is obtained through the interaction between the touchpad and the m...

Problems solved by technology

[0005] However, in the prior art, these two types have some unchangeable technical deficiencies due to their technical characteristics. For example, the electromagnetic touch recognition technology must rely on a stylus that can send signals, so the touch The pen must be equipped with a battery to generate signals; and among them, the capacitive touch recognition technology is affected by other conductors, such as water, because it uses conductive properties

In view of the above, if it is desired to carry out the operation of touch identification in an operating environment with moisture, or even in an underwater operating environment, and at the same time it is not desired to load a battery in the touch object responsible for touch, the existing Electromagnetic or capacitive touch technology can not achieve
