摘要： 监控车辆数量增多、服务器系统负载增加等因素会导致新能源汽车远程监控系统稳定性变差。针对该问题，提出一种基于虚拟车载终端的新能源汽车远程监控系统压力测试方法。采用虚拟车载终端和虚拟Web用户联合测试的方法，记录数据丢帧率、准确率及传输延时。通过测试案例，得到上述指标与系统容量的关系，表明使用该方法能有效测试新能源汽车远程监控系统的极限容量。

Abstract: A virtual on-board terminal based remote monitoring system stress test method is proposed, according to the stability problem caused by the increasing number of monitored automobile and system working load. The method of data generation together by virtual on-board vehicle terminal and virtual user is adopted. Data frame lost rate, accuracy rate, and transport time delay are recorded as stress test’s result. Stress test demonstration is applied and the quantified relationship between the test index and system capacity is found. Example result shows that virtual on-board vehicle terminal based remote monitoring system stress test method is feasible to predict system’s limit capacity.
