For example, when writing on a paper surface, since the paper surface is elastically compressible, the sensitivity of the snap dome 301 needs to be high, otherwise it is impossible to recognize that the pen tip 2 is writing. When the intelligent pen is used for writing on the whiteboard, the whiteboard is hard and has small elasticity, so that the sensitivity of the metal dome can be slightly small, and the pen point 2 can be identified to write, so that the metal dome provided with the hollow part and the swing arm can be subjected to a force of 15g or below 15g, and the intelligent pen can be started sensitively.

Because the signal transmitter 4 transmits a detection signal to the object to be measured around the pen point 2, the signal receiver 5 generates an image of the object to be measured around the pen point 2. When the dome sheet 301 senses the writing pressure of the pen point 2, the circuit of the circuit board is communicated, the signal receiver 5 starts to work, the detection signal reflected by the object to be detected is received, and the analog image data is generated.

The processor 6 is electrically connected with the dome sheet 301 and the signal receiver 5, receives the image data sent by the signal receiver 5, analyzes the image data into digital signals, and generates transmission data packets. When the dome 301 senses the pressure of writing by the pen head 2, the processor 6 starts to work, processes the received analog image data into the data of the digital signal, and then generates a transmission data packet.

The wireless data interface 72 is connected to the processor 6 and transmits the transmission data packet to the upper computer in a wireless manner. The wireless data interface 72 is used for transmitting data packets to the upper computer in a wireless manner, which is convenient and does not require cable connection.

In another non-real-time transmission mode, the processor 6 analyzes the image data into digital signals in real time, encodes the digital signals with a clock and a time axis into standard transmission data packets in real time, stores the standard transmission data packets in the memory 8, and transmits the transmission data packets stored in the memory 8 to an upper computer through the wireless data interface 72 at set time or in other non-real-time modes.
