摘要：本文設計了可用人腦直接進行遠程操控的智能小車系統。該系統基于Mindset腦電耳機把人的腦電信號轉成數字信號，利用Delphi7編程接收耳機信號并提取出其中的“集中度”“冥思度”兩個腦電信號指標，再把這兩個信號指標通過藍牙進行串口透傳，最后發給智能小車的接收部分。小車的MC9S12XS128的芯片接收到“集中度”的數值，結合光電編碼器返回的速度值進而判斷并產生新的PWM波發給直流電機模塊，控制速度；當小車收到“冥思度”的數值達到一定界限，產生舵機的PWM波來控制舵機模塊打角的數值,從而達到人腦直接操控小車的效果。

我們利用這樣的小車也可以主觀的鍛煉腦域的 “集中度”和“冥思度”，為腦機接口產品開發奠定技術基礎。

Abstract: This article is about the available human brain directly to the remote-controlled intelligent vehicle system. The system is based on the Mindset EEG headset and turn a person's brain signals into digital signals, by using Delphi7 programming receive headphone signal and extracting one of the "attention " meditation "two EEG indicators, then via Bluetooth passing through the two signal indicators, at last sent to the receiver portion of the smart car. The chip of the the car MC9S12XS128 receives the value of "attention", combined with the value of the optical encoder rate of return and then identify and generate new PWM wave and sent to the DC motor module to control speed; when the car receives the value of "meditation" to a certain threshold, resulting in the steering gear of the PWM wave to control the steering gear module to play the angle values, so as to achieve the effect of the human brain direct control of the car.

   This car we uses can also be a subjective exercise the degree of concentration and meditation degree of the brain domain, and can be the technological foundation for brain-computer interface product development.
