中文摘要:

随着电动汽车分时租赁商业模式业务蓬勃发展,远程控制作为分时租赁全业务流程中最重要环节,其快速响应程度直接影响全业务流程完整性和用户体验度。目前,电动汽车车载终端主要采用3G LTE、4G LTE、GPRS等无线通信方式,实时向平台管理中心上传车辆运营情况,并接收由平台管理中心下发的远程控制指令。但是在信号恶劣地区,其电动汽车车载终端会出现时延长、响应慢,直接影响用户体验度和平台管理中心对电动汽车的管理力度。为此,本文引入声波通信技术作为辅助通信方式,采用“ASK FSK”复合调制方式,并结合 “双麦录入”的抗干扰技术,研制出具有高抗噪性声波通信功能的电动汽车分时租赁车载终端,实现手机声波对车辆的控制,为保障分时租赁全业务流程流畅性和完整性奠定坚实的技术支撑。

英文摘要:

With the rapid development of time-sharing leasing business model for electric vehicles, remote control as the most important part of the all-service process of time-sharing leasing, the degree of its rapid response directly affects the integrity of business process and the sense of user experience. At present, electric vehicles terminals mainly adopt 3G, LTE, 4G, LTE, GPRS and other traditional wireless communication methods, and upload data to the platform management center in real time, and receive the remote control command from the platform management center by them. However, in the weak signal area, the response of the electric vehicle terminal will become longer and slower, which will directly affect the user experience and the management degree of the electric vehicle management platform management center. Therefore, this paper uses the acoustic communication technology as an auxiliary way, puts forward the "ASK FSK" integrated modulation methods, and combines with the "anti interference technology of wheat double entry". Finally, with high ability of anti-noise acoustic communication function of time-sharing leasing vehicle terminal for electric vehicles is developed, which achieves mobile phone sound wave to control vehicle. This work lays firm technical support for keeping the fluency and integrity of the all-service process of time-sharing leasing.
