尽管城市交通电气化快速发展,但电池电动公交车(EB)车队的系统规划和管理进展却较为落后。本研究首先综述了影响电池电动系统的基本问题,包括充电站部署、电池尺寸、公交车调度和生命周期分析。目前,EB系统的规划和运行是按顺序进行的,公交车调度是在公交车队和基础设施部署完毕后进行的,这导致了资源利用率低和资源浪费。对此,本文提出了混合整数规划模型整合充电站部署和公交车队管理,以尽可能低的生命周期成本(LCC),包括所有权、运营、维护和排放费用,缩小最佳规划与运营之间的差距。引入了分支定价算法,以减少寻找最佳解决方案所需的计算工作量。本研究还通过分析真实案
例,与目前的公交运营策略和充电站布局相比,一条公交线路的LCC优化后可显著降低30.4%。提出的方法不仅可以进行生命周期分析,还可以为交通部门和运营商提供可靠的充电桩部署及单线和多线的公交调度计划,这两者都是未来具有高电气化普及率的交通系统中决策支持的关键要求,此研究也有助于推动可持续交通的发展。

针对CAN总线中消息在固定优先级调度(FPS)算法下传输不可预知、低优先级消息容易被阻塞的问题,提出了一种基于时间触发机制的固定优先级调度(TT-FPS)算法,给出了最糟糕响应时间的计算方法。然后以纯电动汽车消息系统为例进行了TT-FPS的性能分析,验证了TT-FPS 较FPS有更好的性能。

With the development of new materials and ultra-precision processing technology, the sizes of measured objects increase, and the requirements for machining accuracy and surface quality become more exacting. The traditional measurement method based on reference datum is inadequate for measuring a high-precision object when the quality of the reference datum is approximately within the same order as that of the object. Self-referenced measurement techniques provide an effective means when the direct reference-based method cannot satisfy the required measurement or calibration accuracy. This paper discusses the reconstruction algorithms for self-referenced measurement and connects lateral shearing interferometry and multi-probe error separation. In lateral shearing interferometry, the reconstruction algorithms are generally categorized into modal or zonal methods. The multi-probe error separation techniques for straightness measurement are broadly divided into two-point and three-point methods. The common features of the lateral shearing interferometry method and the multi-probe error separation method are identified. We conclude that the reconstruction principle in lateral shearing interferometry is similar to the two-point method in error separation on the condition that no yaw error exists. This similarity may provide a basis or inspiration for the development of both classes of methods.
