Title:
POSITION DETECTION SYSTEM AND DIGITAL HANDWRITING PEN
Document Type and Number:
WIPO Patent Application WO/2020/147638
Kind Code:
A1
Abstract:
A position detection system, comprising a power supply module 10, a detection module 50, a control module 30, and a pulse module 70. The power supply module 10 is used for supplying power, so as to ensure that parts in the position detection system are operated normally. The detection module 50 comprises a key detection circuit 51, a pressure detection circuit 53, and an angle detection circuit 55; the key detection circuit 51 is used for providing key detection data and the key detection data is output after being processed by means of the control module 30; and the pressure detection circuit 53 is used for providing pressure detection data and the pressure detection data is output after being processed by means of the control module 30. The control module 30 is used for outputting a signal after the detection data are processed. The pulse module 70 is connected to the control module 30, and the pulse module 70 is used for obtaining starting references of a key signal and a pressure signal output by the control module 30, and converting the key signal and the pressure signal into digital signals by formal coding and then sending the digital signals to a handwriting board. Compared with the related art, the position detection system and the digital handwriting pen have better stability.
