The smart pen housing is injection molded using, for example, a thermoplastic comprising polycarbonate and ABS plastic. Other materials such as thermoset plastics or metals may also be used for the smart pen housing. Shaping can also be carried out, for example, by casting or milling.
In manufacturing the smart pen, it is also suitable to mount one or more main circuit boards within the pen housing of the pen. One or more processors, memory units and image capture components, as well as wiring, charging jacks and the like may also be mounted on/integrated with the main circuit board(s). The camera unit is then connected to the processor using a flexible electrical coupling. Additional components such as a battery may be installed inside the pen prior to sealing the pen housing, for example by joining the two halves. The housing may be of an engineering plastic, and typically includes two shells that can be snapped together to hold other devices within the housing. The two casings which can be buckled can be divided into a pen body casing with a left-right structure and a pen body and pen cap casing with an up-down structure.
The intelligence pen includes: the pen comprises a shell 1, a pen core, a pressure sensor, a signal transmitter, a signal receiver, a processor and a wireless data interface. The signal emitter and the signal receiver can be an image acquisition component integrating light-emitting secondary light and a camera unit. A reset key 3 is also included.
The pen point of the pen core extends out of the pen shell, and the pen core is used for writing, namely strokes and orders are generated, and the pen core can be written on a paper surface and a whiteboard. If the writing paper is used for writing, the refill can be an oil (ball-point pen) refill, a water (neutral) refill, a pencil refill, an erasable (ink decomposition) refill, an erasable (ink solidification) refill, a plastic (PP, PET, PVC and the like) refill and the like. 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.
When the pen core is used for writing, the generated pressure is transmitted to the pressure sensor, a sensing signal is generated, and the processor, the signal transmitter and the signal receiver are started.
The pressure sensor is used for indicating that the pen core is written and the intelligent pen needs to work. The pressure sensor can be matched differently according to the use scene of the intelligent pen. For example, when writing on a paper surface, the sensitivity of the pressure sensor needs to be higher because the paper surface is elastically compressible, otherwise it is impossible to recognize that the pen core is writing. When the pen is used for writing on the whiteboard, the whiteboard is hard and has low elasticity, so that the sensitivity of the pressure sensor can be slightly small, and the pen core can be identified to be written.
The signal emitter is connected with the pressure sensor and emits detection signals to the object to be detected around the pen point. When the pressure sensor senses the pressure of writing by the pen core, the signal transmitter starts to work and transmits signals. The signal generator may be a transmitter that transmits sound waves, ultrasonic waves, infrared rays, ultraviolet rays, visible light (of various wavelength bands), X-rays, gamma rays, or the like.
Optionally, the signal emitter emits the detection signal in a plurality of 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 tip.
The signal receiver is connected with the pressure sensor, receives the detection signal reflected from the object to be detected, and generates image data. The image data at this time is an analog signal. The signal receiver needs to be matched with the signal transmitter to receive the detection signal reflected from the object to be measured. Because the emitter emits a detection signal to the object to be measured around the pen core, the signal receiver generates an image of the object to be measured around the pen core. When the pressure sensor senses the pressure of writing by the pen core, the signal receiver starts to work, receives the detection signal reflected by the object to be detected, and generates analog image data.
The processor is connected with the pressure sensor and the signal receiver, receives the image data sent by the signal receiver, analyzes the image data into digital signals and generates transmission data packets. When the pressure sensor senses the pressure of writing by the pen core, the processor starts to work, the received analog image data is processed into digital signal data, and then a transmission data packet is generated.
Optionally, when the pressure sensor senses the pressure of writing by the pen core, pressure sensing data is generated and sent to the processor, the processor analyzes the image data into a digital signal, and the digital signal, the pressure sensing data sent by the pressure sensor, the clock and a time axis are encoded into a standard transmission data packet.
The wireless data interface is connected with the processor and transmits the transmission data packet to the upper computer in a wireless mode. The wireless data interface is used for transmitting a data packet to an upper computer in a wireless mode, and the wireless mode is convenient and does not need cable connection. 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 an upper computer by utilizing a communication network.
And the upper computer acquires the image information of the object to be detected around the pen point according to the transmission data packet, and realizes accurate positioning and synchronous data electronization by utilizing a dot matrix technology. The whole intelligent pen is added with intelligent systems such as a processor, so that the intelligent pen can be restarted through the reset key 3 when system disorder occurs.
The utility model discloses an intelligence pen still includes: memory, power, switching circuit.
The memory is connected with the processor and used for storing the image data and transmitting the data packet. The wireless data interface transmits the transmission data packet stored in the memory to the upper computer in a wireless mode.
It should be noted here that there are two situations in which the wireless data interface transmits the transmission data packet to the upper computer, one is real-time transmission, the processor analyzes 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 wireless data interface transmits the transmission data packet to the upper computer in real time in a wireless manner. The other is non-real-time transmission, the processor analyzes the image data into digital signals in real time, and the digital signals, the pressure sensing data sent by the pressure sensor, the clock and the time shaft are coded into standard transmission data packets in real time and then stored in the memory, and then the transmission data packets stored in the memory are transmitted to the upper computer by the wireless data interface at set time or in other non-real-time modes.
The power supply is connected with the pressure sensor, the processor, the signal transmitter and the signal receiver. The purpose of the power supply is to power the pressure sensor, the processor, the signal transmitter and the signal receiver.
In particular, the power source may be a battery, such as a rechargeable battery.
The switch circuit is connected with the power supply, is used for controlling the power supply to supply power to the pressure sensor, the processor, the signal transmitter and the signal receiver, and can be realized by using a hard switch.
In addition, the smart pen can further comprise a first circuit board and a second circuit board which are flexibly connected, the switch circuit and the wireless data interface are located on the first circuit board, and the pressure sensor, the processor, the signal transmitter and the signal receiver are located on the second circuit board.
