Development Of An Intelligent Dart Target Based On Matrix Multi-pressure Sensors

With the rapid development of science and technology,smart entertainment devices have entered people's lives and are widely used in people's daily lives.In the modern society,people's economic level and quality of life are improving,and people's demand for entertainment products is increasing.At present,there are still many smart entertainment devices with low technical level,single function structure and lack of fun in the market.In response to this phenomenon,this design applies the filtering algorithm and image processing technology to the embedded hardware platform according to the various needs of smart hardware products in the direction of entertainment products,and uses it with the mobile We Chat public platform to increase the interest of users.An intelligent dartboard system based on pressure sensor is designed.According to the overall requirements of the smart dart target,the various functional requirements are completed and the control scheme required by the system and the overall framework of the design system are given.The hardware part of the intelligent dart target control system is divided into a main controller unit,a power system unit,a user data acquisition unit and a data output unit.On this basis,after the sensor signal is generated,a filtering algorithm is added to ensure the accuracy and integrity of the signal transmission,and the image processing method is used to make the intelligent dart target process data efficiently.The main control chip adopts the Raspberry Pi development board,which can complete this design because of its excellent performance.This paper determines the selection of other chips according to the design requirements and the overall framework,and designs the hardware and software of each module separately.And effectively put forward debugging programs to ensure the feasibility of the design.In the actual debugging process,the communication,filtering and scoring functions of the Raspberry Pi and the ultrasonic module are first debugged,and then the entire smart dart target is debugged.The experiment proves that the overall function of the intelligent dart target can be realized,the accuracy is reliable and the response is sensitive.
