Independent double-coil wireless passive electromagnetic antenna board wiring system and working method thereof

Abstract

The invention belongs to the technical field of electronic information input equipment, and particularly relates to an independent double-coil wireless passive electromagnetic antenna board wiring system and a working method thereof. According to the independent double-coil wireless passive electromagnetic antenna board wiring system, the transmitting coil array and the receiving coil array are orderly arranged on the two surfaces of the antenna board and are independently and separately arranged, so that the situation that the same group of coils are multiplexed for transmitting and receiving is avoided, and therefore, an independent multi-group control circuit coil array is realized; sufficient wireless transmitting signals and stable receiving signals are provided, so that the wireless passive non-contact induction type electromagnetic handwriting pen can continuously work, and the control circuit module can accurately and quickly perform data processing on input signals of the wireless passive non-contact induction type electromagnetic handwriting pen; the problems of large data calculation deviation, poor anti-interference performance, size limitation and the like caused by insufficient transmitting power and unstable received signals in the traditional technical scheme are solved.

Description

technical field [0001] The invention belongs to the technical field of electronic information input devices, and in particular relates to an independent dual-coil wireless passive electromagnetic antenna board wiring system and a working method thereof. Background technique [0002] At present, the traditional electromagnetic induction antenna board wiring structure is that the transmitting coil and the receiving coil are the same set of coils, mainly through multiple antenna loops juxtaposed, overlapping each other on the same level, serving as both a receiving loop and a sending loop. The traditional electromagnetic antenna board uses a single common coil wiring method, which will lead to low switching efficiency between the electromagnetic antenna board's transmission and reception, insufficient transmission power and unstable receiving signals, which makes the electromagnetic stylus suitable for it unable to receive continuous power supply. And the received signal is uns...

AI Technical Summary

Problems solved by technology

The traditional electromagnetic antenna board only adopts the wiring method of shared coils, which will lead to low switching efficiency between the electromagnetic antenna board's transmission and reception, insufficient transmission power and unstable reception signal, so that the electromagnetic stylus that it adapts cannot receive continuous power supply And the receiving signal is unstable, so it is impossible to quickly obtain the required energy signal and corresponding frequency

Therefore, in the traditional technical solution, there are problems such as insufficient transmission power and unstable received signal, resulting in large data calculation deviation, poor anti-interference performance and limited size.
