摘 要：在车辆的生产过程中，除了需要确保车辆装配正常，还需要确保各个零件功能正常才能确保车辆正常下线。传统的车辆下线检测系统，需要人为的对车辆的识别码、车载终端的各路参数进行人工记录和比对，再将参数录入后台系统，耗费人力较多，检测耗时也较长，车辆下线检测的效率也较低。同时，通常的下线检测过程中，未对车载设备的正常运行进行判断，如果将问题车载终端装车下发，会导致监控平台无法对该车辆进行正常监控，存在安全隐患，也不满足相关要求，同时增加售后维护成本。基于此，本文设计开发了一种新能源汽车车载终端下线检测系统，实现了新能源车辆在出厂时，通过检测时，由检测人员操作该系统来查看终端工作状态，系统自动根据终端返回平台信息判断该终端工作是否正常，然后把结果反馈至生产系统。

Design of Off-line Detection System for New Energy Vehicle On-board Terminal

Huang Lihua Gui Kangzhe Zhuang Jining Zhang Liang Huang Zupeng

Abstract：In the production process of vehicles， in addition to ensuring the normal assembly of the vehicle， it is also necessary to ensure that the functions of each part are normal to ensure the normal off-line of the vehicle. The traditional vehicle off-line detection system needs to manually record and compare the vehicle identification code and various parameters of the vehicle terminal， and then enter the parameters into the background system， which consumes more manpower and time-consuming detection. The efficiency of offline detection is also low. At the same time， in the usual offline detection process， the normal operation of the on-board equipment is not judged. If the problematic on-board terminal is loaded and issued， the monitoring platform will not be able to monitor the vehicle normally. There are potential safety hazards， and the relevant requirements are not satisfied， while increasing after-sales maintenance costs. Based on this， this paper designs and develops a new energy vehicle vehicle-mounted terminal offline detection system， which realizes that when the new energy vehicle leaves the factory， when the new energy vehicle passes the inspection， the inspector operates the system to check the working status of the terminal， and the system automatically returns to the platform according to the terminal. The information determines whether the terminal is working normally， and then feeds the result back to the production system.
