【摘要】 随着社会不断发展,人民生活水平逐渐提高,人均拥有轿车数量不断增加,同时,移动互联网也在不断发展,为了方便人们出行,滴滴等网约车应运而生,随着而来的是一系列终端服务。现在网约车十分流行,智能手机均搭载全球定位系统,通过手机定位,司机和乘客都能很好的知道对方所在的地理位置,然而GPS毕竟还有5米的可允许误差,夜晚的人们视野十分模糊,开发一个将客户特征信息推送到显示屏幕上的终端,方便乘客更好的认清自己的网约车。该终端将手机Android操作系统的开源性与无线蓝牙模块完美结合,司机可以方便快捷地传递客户特征信息。基于网约车客户特征信息推送终端将丰富现在网约车的发展,给司机和乘客带来便利。该终端的工作流程如下:司机通过基于android系统的手机app输入网约车客户特征信息,手机app调用底层蓝牙驱动使用socket通信方式将网约车的特征信息推送到信息显示端的蓝牙模块,信息显示端核心板MCU通过串口接收该信息,并将该信息驱动显示至16×64点阵上。更多还原

【Abstract】 With the continuous development of society,people’s living standards are gradually improving,and the number of cars per capita is increasing.At the same time,the mobile Internet is also constantly developing.In order to facilitate people’s travel,drip-drip and other networking vehicles came into being,along with a series of terminal services.Nowadays,Internet car appointment is very popular.Smartphones are equipped with global positioning system.Through mobile phone positioning,drivers and passengers can know each other’s geographical location very well.However,GPS still has 5 meters of allowable error after all.People’s vision at night is very blurred.Develop a way to push customer’s characteristic information to the display screen.The terminal is convenient for passengers to better understand their own network appointment car.The terminal perfectly combines the open source of Android operating system and Bluetooth module,and the driver can easily and quickly transmit the customer’s characteristic information.The push terminal based on customer characteristic information will enrich the development of online reservation car and bring convenience to drivers and passengers.The work flow of this terminal is as follows: the driver inputs the customer’s characteristic information of network appointment through the mobile app based on Android system,and the mobile app calls the underlying Bluetooth driver to push the characteristic information of network appointment vehicle to the Bluetooth module of the information display terminal by using socket communication mode.The MCU of the core board of the information display terminal receives the information through the serial port and receives the information through the serial port.The information driver is displayed on 16*64 lattice.更多还原
