给自卸汽车车槽内自动喷油的装置

在公路工程施工中 ,需要用自卸车把沥青混凝土拌和站生产的沥青混凝土运输至摊铺现场。在自卸车装沥青混凝土前 ,需用柴油和水的混合液或肥皂水把图 1　原理图自卸车的车槽内壁润滑一遍 ,以便在自卸车向摊铺机内卸料时沥青混凝土不至于粘在车槽内壁上。以往需用民工爬上爬下用拖把醮柴油和水的混合液把车槽内壁擦一遍 ,劳动强度很大。为了解决这个问题 ,我们设计制作了一种装置 ,其原理见图 1。它的两个喷油嘴安装在沥青混凝土拌和站主机楼一层下面如图 2所示 ,两个喷油嘴之间的图 2　安装位置距离可以根据车槽的宽度进行调整。该装置的使用…     

红旗世纪星怠速抖动

故障现象一辆装备NISSAN公司生产的VG20E型V6多点燃油喷射发动机、016型手动变速器的红旗世纪星轿车CA7202E3,行驶里程140000km。怠速时发动机轻微抖动,排气管发出“突突”声,加速和匀速行驶均正常。故障诊断与排除该车在来我厂之前,已在一家修理厂进行过怠速控制阀、喷油器、气门及进气歧管清洗,但故障现象依旧。笔者接车后首先利用诊断仪读取发动机控制单元故障码,诊断仪显示系统工作正常。阅读当前数据,未发现问题。测量进气歧管真空度45kPa,说明怠速时汽缸真空吸力偏低,可能存在汽缸密封不良或进气歧管漏气故障。分别拔开各缸喷油…     

S^2 BHCA Multiple AUVs cooperation oriented control architecture

Oceanographic survey, or other similar applications should be the applications of multiple AUVs. In this paper, the skill ＆ simulation based hybrid control architecture （S^2BHCA） as the controller＇s design reference was proposed. It is a multi-robot cooperation oriented intelligent control architecture based on hybrid ideas. The S^2BHCA attempts to incorporate the virtues of the reactive controller and of the deliberative controller by introducing the concept of the ＂skill＂. The additional online task simulation ability for cooperation is supported, too. As an application, a multiple AUV control system was developed with three ＂skills＂ for the MCM mission including two different cooperative tasks. The simulation and the sea trials show that simple task expression, fast reaction and better cooperation support can be achieved by realizing the AUV controller based on the S^2BHCA.
