The function of the pressure sensor 3 is to indicate that the pen head 2 is writing and the high-comfort intelligent pen needs to work. The pressure sensor 3 can be matched differently according to the use scene of the high-comfort intelligent pen. For example, when writing on a paper surface, the sensitivity of the pressure sensor 3 needs to be higher because the paper surface is elastically compressible, otherwise it is not possible to recognize that the pen tip 2 is writing. When writing on the whiteboard, because the whiteboard is hard and has little elasticity, the sensitivity of the pressure sensor can be slightly smaller, and the pen point 2 can be identified to be writing.

The signal emitter 4 is connected with the pressure sensor 3 and emits a detection signal to the object to be detected around the pen point. When the pressure sensor 3 senses the pressure of the pen point 2 for writing, the signal emitter 4 starts to work and emits signals.

Since the transmitter 4 transmits a detection signal to the object to be measured around the pen head 2, the signal receiver 5 generates an image of the object to be measured around the pen head 2. When the pressure sensor 3 senses the pressure written by the pen point 2, the signal receiver 5 starts to work, receives the detection signal reflected by the object to be detected and generates analog image data.

The processor 6 is connected to the pressure sensor 3 and the signal receiver 5, receives the image data transmitted from the signal receiver 5, and analyzes the image data into a digital signal to generate a transmission data packet. When the pressure sensor 3 senses the pressure of writing of the pen point 2, the processor 6 starts to work, processes the received analog image data into digital signal data and then generates a transmission data packet.

Optionally, when the pressure sensor 3 senses the pressure written by the pen point 2, pressure sensing data is generated and sent to the processor 6, and the processor 6 analyzes the image data into a digital signal and encodes the digital signal, the pressure sensing data sent by the pressure sensor, the clock and a time axis into a standard transmission data packet.
