Dot matrix digital pen

Abstract

The invention relates to a dot matrix digital pen. The dot matrix digital pen comprises a shell, a pen refill, a pressure sensor, a signal transmitter, a signal receiver, a processor and a data interface, wherein a pen point of the pen refill stretches out of the shell; the pressure sensor is connected with the tail end of the pen refill; when pressure generated by using the pen refill to write is transmitted to the pressure sensor, a sensing signal is generated to start the processor, the signal transmitter and the signal receiver; the signal transmitter is connected with the pressure sensor and is used for transmitting a detection signal to a to-be-detected object at the periphery of the pen point; the signal receiver is connected with the pressure sensor and is used for receiving the detection signal reflected by the to-be-detected object to generate image data; the processor is connected with the pressure sensor and the signal receiver, and is used for receiving image data transmitted by the signal receiver, analyzing the image data into a digital signal and generating a transmission data packet; and the data interface is connected with the processor and is used for transmitting the transmission data packet to an upper computer. According to the dot matrix digital pen, a dot matrix technology is used for realizing accurate positioning and synchronous data electronization; and the dot matrix digital pen is small in volume, strong in environmental adaptability and relatively low in power.

Description

technical field [0001] The invention relates to a dot-matrix digital pen, in particular to a digital optical dot-matrix digital pen. Background technique [0002] There are many types of existing digital pens, such as using optical scanning imaging to generate electronic bitmaps. Or use the transmitter to emit positioning radio waves, encounter obstacles (targets) and reflect echoes, and determine the direction and distance to determine the position and trajectory of obstacles (targets). There are also, for example, induction and electromagnetic technologies. [0003] And these prior art have following shortcoming: [0004] Low positioning accuracy, non-vector electronic data, susceptible to interference, complex devices, difficult to deploy and use, etc. Contents of the invention [0005] The object of the present invention is to provide a dot-matrix digital pen for the defects of the prior art, which utilizes dot-matrix technology to realize precise positioning and sy...
