The utility model provides an intelligent pen, as shown in figure 1, figure 2, as shown in the figure, the utility model discloses a dot matrix intelligence pen includes:

the pen comprises a pen shell 1, wherein a support is arranged in the pen shell 1, and a pressure sensor 3, a signal transmitter 4, a signal receiver 5 and an interface A are arranged on the support; a pen core 2; the pen cap 11 covers the pen shell 1.

The pen casing 1 may be made of engineering plastic, and generally includes two lockable pen casings, and other devices are accommodated in the pen casing 1.

The pen point of the pen core 2 extends out of the pen shell, and the pen core 2 is used for writing, namely strokes and orders are generated, and the strokes can be written on paper or a whiteboard. If writing on paper, the refill may be an oil (ball-point) refill, a water (neutral) refill, a pencil refill, an erasable (ink-decomposing) refill, an erasable (ink-curing) refill, a plastic (PP, PET, PVC, etc.) refill, etc. If the writing is written on the white board, the white board can be a handheld white board or a white board externally hung and adhered on the wall surface.

And the pressure sensor 3 is connected with the tail end of the pen core 2, and pressure generated when the pen core 2 writes is transmitted to the pressure sensor 3 to generate a sensing signal, so that the processor 6, the signal transmitter 4 and the signal receiver 5 are started.

The pressure sensor 3 is used for indicating that the pen core 2 is written and the dot matrix intelligent pen needs to work. The pressure sensor 3 can be matched differently according to the use scene of the lattice intelligent pen. For example, when writing on a paper surface, since the paper surface is elastically compressible, the sensitivity of the pressure sensor 3 needs to be high, otherwise it is impossible to recognize that the pen core 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 writing pen core 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 writing by the pen core 2, the signal transmitter 4 starts to work and transmits a signal. The signal generator 4 may be a transmitter that transmits sound waves, ultrasonic waves, infrared rays, ultraviolet rays, visible light (each band), X-rays, gamma rays, or the like.

Optionally, the signal emitter 4 emits the detection signal in various ways, specifically, in a continuous or fixed frequency or variable frequency or frequency modulation way, to emit the detection signal to the object to be detected around the pen point.

The signal receiver 5 is connected to the pressure sensor 3, and receives a detection signal reflected from the object to be measured to generate image data. The image data at this time is an analog signal. The signal receiver 5 needs to be matched with the signal transmitter 4 to receive the detection signal reflected from the object to be measured. Since the transmitter 4 transmits a detection signal to the object to be measured around the pen core 2, the signal receiver 5 generates an image of the object to be measured around the pen core 2. When the pressure sensor 3 senses the writing pressure of the pen core 2, the signal receiver 5 starts to work, receives a detection signal reflected by an 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 written by the pen core 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 sensing the pressure written by the pen core 2, the pressure sensor 3 generates pressure-sensitive data and sends the pressure-sensitive data to the processor 6, and the processor 6 analyzes the image data into a digital signal and encodes the digital signal, the pressure-sensitive data sent by the pressure sensor, the clock and a time axis into a standard transmission data packet.

The data interface 7 is connected to the processor 6 and transmits the transmission data packets to the terminal device. The data interface 7 is used for transmitting data packets to the terminal equipment in a wired or wireless mode, because the wired mode is stable and the data packets are not easy to lose. Specifically, the wired data interface may be a USB port, a MiniUSB port, a microsusb port, a parallel port, or a serial port; because the wireless mode is more convenient, cable connection is not needed, and specifically, the wireless data interface is a Bluetooth interface, an infrared interface, a Wifi interface, a 2.4-5.0GHz band interface or a wireless communication interface. The Bluetooth interface, the infrared interface, the Wifi interface and the 2.4-5.0GHz band interface are used for wireless local area network communication, and the communication interface can utilize 2G, 3G or 4G technology to communicate with the terminal equipment by utilizing a communication network.

The intelligent pen further comprises an interface B which is connected with the interface A to obtain the image data received by the processor 6 and sent by the signal receiver 5, and the image data is analyzed into digital signals to generate transmission data packets which are transmitted to the terminal equipment.

The terminal equipment comprises a mobile phone and a computer, and receives the data packet of the intelligent pen through the B interface.

As shown in the figure again, the utility model discloses a dot matrix intelligence pen still includes: memory 8, power supply 10, switching circuit 9.

The memory 8 is connected to the processor 6 and stores image data and transmission data packets. The data interface 7 transmits the transmission packet stored in the memory 8 to the terminal device by wire.

It should be noted here that there are two cases in which the data interface 7 transmits the transmission data packet to the terminal device, one is real-time transmission, the processor 6 parses the image data into digital signals in real time, and encodes the digital signals with the pressure-sensitive data sent by the pressure sensor and the clock and time axis into a standard transmission data packet in real time, and then the data interface 7 transmits the transmission data packet to the terminal device in real time through a wired or wireless manner. In another non-real-time transmission mode, the processor 6 analyzes the image data into digital signals in real time, and encodes the digital signals with pressure sensing data sent by the pressure sensor and the clock and time axis into standard transmission data packets in real time and then stores the standard transmission data packets in the memory 8, and then transmits the transmission data packets stored in the memory 8 to the terminal equipment by the data interface 7 at set time or in other non-real-time modes.

The power supply 10 is connected with the pressure sensor 3, the processor 6, the signal transmitter 4 and the signal receiver 5. The purpose of the power supply 10 is to supply power to the pressure sensor 3, the processor 6, the signal transmitter 4, the signal receiver 5.

Specifically, the power supply 10 may be a battery, such as a rechargeable battery, connected to the data interface 7, and the data interface 7 integrates a power supply interface to charge the power supply 10. If the data interface is a MiniUSB port or a MicroUSB port, the data can be transmitted and power can be supplied.
