接线方法

时间继电器的电气控制系统中是一个非常重要的元器件。一般分为通电延时和断电延时两种类型。 从动作的原理上有电子式、机械式等。电子式的是采用电容充放电再配合电子元件的原理来实现延时动作。机械式的样式较多,有利用气囊、弹簧的气囊式。

时间继电器的接线方法:

1、控制接线:把它看成直流继电器来考虑。

2、工作控制:虽然控制电压接上了,但是是否起控制作用,由面板上的计时器决定。

3、功能理解:它就是一个开关,单刀双掷的,有一个活动点活动臂,就像常见的闸刀开关的活动刀臂一样。

4:负载接线:电源的零线或负极接用电器的零线或负极端。

5、工作原理:计时无效期间,相当于平常电灯开关断开状态。有效时,继电器动作,用电器得电工作,相当于平常电灯开关接通状态。

时间继电器的原理是什么?

时间继电器中1、2称为常闭触点,触点1、3间称为常开触点,底座有标示1到8脚, 2和7线圈,13常开14常闭,即时,86常开,85常闭,延时。时间继电器当加入(或去掉)输入的动作信号后,其输出电路需经过规定的准确时间才产生跳跃式变化(或触头动作)的一种继电器。是一种使用在较低的电压或较小电流的电路上,用来接通或切断较高电压、较大电流的电路的电气元件。扩展资料:时间继电器的主要功能是作为简单程序控制中的一种执行器件,当它接受了启动信号后开始计时,计时结束后它的工作触头进行开或合的动作,从而推动后续的电路工作。一般来说,时间继电器的延时性能在设计的范围内是可以调节的,从而方便调整它的延时时间长短。单凭一只时间继电器恐怕不能做到开始延时闭合,闭合一段时间后,再断开,先实现延时闭合后延时断开,但总体上说,通过配置一定数量的时间继电器和中间继电器都是可以做到的。参考资料来源:百度百科-时间继电器

时间继电器调试

时间继电器的调整流程如下:1、用手按电磁机构的唧子到吸合位置,延时机构立即启动,直到延时触点闭合为止。此时瞬时转换触点应可靠转换。2、释放唧子时(在工作位置),动触点应迅速返回原位,瞬时转换触点应可靠转换。3、当唧子吸入时,唧子端部的动板不得与延时机构中的扇形齿板相碰,若相碰时,可将动板下移至适当位置,然后将螺钉固紧即可。注:时间继电器工作原理:计时无效期间,相当于平常电灯开关断开状态。有效时,继电器动作,用电器的电工作,相当于平常电灯开关接通状态。扩展资料:时间继电器的接线方法:1、控制接线:把它看成直流继电器来考虑;2、工作控制:虽然控制电压接上了,但是是否起控制作用,由面板上的计时器决定;3、功能理解:它就是一个开关,单刀双掷的,有一个活动点活动臂,就像常见的闸刀开关的活动刀臂一样;4、负载接线:电源的零线或负极接用电器的零线或负极端。参考资料来源:百度百科-电子式时间继电器参考资料来源:百度百科-时间继电器

24伏时间继电器的工作原理和接线方法

什么是24伏时间继电器 24伏时间继电器是一种电子开关,可以控制电路的开关,使其完成特定的操作。在智能家居系统、自动控制电路等应用中广泛使用,其工作原理简单而有效,非常适合需要自动化控制的场景。24伏时间继电器的工作原理 24伏时间继电器的工作原理基于电磁铁的原理。当在电磁铁绕组上通过电流时,会产生一个磁场。在24伏时间继电器中,通过在电磁铁绕组上加电流来产生磁场,磁场会吸引一个铁芯,使其拉动一个开关,从而改变电路的状态。更具体地说,24伏时间继电器的电磁铁上有两个绕组:一个是控制绕组,用于接受控制信号;另一个是动作绕组,用于产生强磁场。当电路中的电流通过控制绕组时,会产生一个磁场,这个磁场会被动作绕组吸收,从而产生比控制绕组更强的磁场。这个磁场会吸引铁芯,使其拉动一个开关,从而改变电路的状态。24伏时间继电器的接线方法 24伏时间继电器的接线方法相对简单,只需要按照正确的顺序连接继电器和电路即可。下面是一种常见的24伏时间继电器的接线方法:1.将24伏时间继电器的控制端口(通常标有COM)连接到电路的负极,将24伏时间继电器的NO(Normally Open)端口连接到电路的正极,这样24伏时间继电器开关打开时电路会通电。2.将24伏时间继电器的控制绕组连接到控制信号源,如一个开关、传感器等。当控制信号出现时,控制绕组会产生一个磁场,从而使24伏时间继电器动作,改变电路的状态。注意:在接线时一定要注意极性,将正极和负极接错可能会导致电路短路,从而损坏电器设备。总结 24伏时间继电器是一种非常实用的电器设备,通过简单的电磁铁原理实现了电路的自动控制,广泛应用于智能家居系统、工业控制、自动化设备等领域。24伏时间继电器的接线方法非常简单,但在接线时还是要注意极性,以确保电路的正常工作。

JS14P时间继电器工作原理

工作原理当线圈通电时,衔铁及托板被铁心吸引而瞬时下移,使瞬时动作触点接通或断开。但是活塞杆和杠杆不能同时跟着衔铁一起下落,因为活塞杆的上端连着气室中的橡皮膜,当活塞杆在释放弹簧的作用下开始向下运动时,橡皮膜随之向下凹,上面空气室的空气变得稀薄而使活塞杆受到阻尼作用而缓慢下降。经过一定时间,活塞杆下降到一定位置,便通过杠杆推动延时触点动作,使动断触点断开,动合触点闭合。从线圈通电到延时触点完成动作,这段时间就是继电器的延时时间。延时时间的长短可以用螺钉调节空气室进气孔的大小来改变。吸引线圈断电后,继电器依靠恢复弹簧的作用而复原。空气经出气孔被迅速排出。

生石灰做干燥剂原理?

生石灰作为干燥剂的原理是由于生石灰可以吸收空气中的水分,而生石灰吸收水分后会生成氢氧化钙,能与空气中的二氧化碳反应生成碳酸钙和水,因此生石灰干燥剂用过一段时间后,需进行更换,否则其自身会蒸发水分,增加空气湿度。生石灰的主要成分是氧化钙即CaO,能与水发生化学反应生成熟石灰(氢氧化钙)。CaO+H2O=Ca(OH)2熟石灰在空气中放置,又可与空气中的二氧化碳发生新的化学反应生成稳定的碳酸钙。Ca(OH)2+CO2=CaCO3↓+H2O。生石灰的通常制法为将主要成分为碳酸钙的天然岩石,在高温下煅烧,即可分解生成二氧化碳以及氧化钙。凡是以碳酸钙为主要成分的天然岩石,如石灰岩、白垩、白云质石灰岩等,都可用来生产石灰。在沿海地区有用贝壳作原料,经烧制成壳灰,作生石灰用。生石灰是采用化学吸收法除去水蒸气的常用干燥剂,也用于钢铁、农药、医药、干燥剂、制革及醇的脱水等。特别适用于膨化食品、香菇、木耳等土特产,以及仪表仪器、医药、服饰、电子电讯、皮革、纺织等行业的产品。

雷达的有关知识( 快速 )

分类: 社会民生 >> 军事 问题描述: 快速快速快速快速快速快速快速快速快速快速快速快速快速 解析: 雷达 雷达是20世纪人类在电子工程领域的一项重大发明。雷达的出现为人类在许多领域引入了现代科技的手段。 1935年2月25日,英国人为了防御敌机对本土的攻击,开始了第一次实用雷达实验。当时使用的媒体是由BBC广播站发射的50米波长的常规无线电波,在一个事先装有接收设备的货车里,科研人员在显示器上看到了由飞机反射回来的无线电信号的回波,于是雷达产生了。雷达是利用极短的无线电波进行探测的,雷达的组成部分有发射机、天线、接收机和显示器等。由于无线电波传播时,遇到障碍物就能反射回来,雷达就根据这个原理把无线电波发射出去,再用接收装置接收反射回来的无线电波,这样就可以测定目标的方向、距离、高度等。最初雷达主要用于军事。第二次世界大战期间,英国在海岸线上建起了雷达防御网络。这些早期的雷达使英国人能够不断地成功抗击德军破坏性的空中和海底袭击。 雷达被人们称为千里眼。在现代战争中,由于雷达技术的进步,使交战双方在相距几十公里,甚至上百公里,人还互相看不到,就已拉开了空战序幕,这就是现代空战利用雷达的一个特点――超视距空战。 由于雷达自身的工作原理,造成了雷达在使用中存在有捕捉对象的盲区,这也就有了在战争中利用雷达盲区偷袭成功的战例。现代战争中,为了躲避雷达的监视,美国生产出了一种隐形轰炸机,它可以有效驱散雷达信号,使它对于常规的雷达系统保持隐形。正是由于这种矛与盾的关系,科学家在这个领域不断探索研制分辨能力更高的雷达。 随着雷达技术的不断改进,如今雷达被广泛用于民航管制、地形测量、气象、航海等众多领域。面对日益拥挤的天空,拥有精密的雷达监测系统至关重要。使用雷达设备可不受天气的影响,不分昼夜进行监测。民航管制员通过雷达直接获取飞机的位置、高度、航行轨迹等信息,及时调节飞行方位和高度。在雷达的使用科学原理中,雷达与目标之间有相地运动,回波信号的频率有多普勒频移,根据多普勒效应的原理可以求得其相对速度。这也是交通警在公路上测量汽车速度的测速雷达工作的原理。 我国在雷达技术方面发展很快,取得了很大成就。探地雷达就是我国研制的,它可适用于不同深度的地下探测。目前,探地雷达已经广泛应用于国防、城市建设、水利、考古等领域。中科院电子所研制成功了星载合成孔径雷达模拟样机,并对1998年长江中下游特大洪涝灾害进行了监测,获取了受灾地区的图像,为抗洪救灾提供了准确的灾情数据。随着高科技的不断发展,雷达技术将在21世纪得到更广泛的应用。 雷达的历史 1922年 美国泰勒和杨建议在两艘军舰上装备高频发射机和接收机以搜索敌舰。 1924年 英国阿普利顿和巴尼特通过电离层反射无线电波测量赛层的高度。美国布莱尔和杜夫用脉冲波来测量亥维塞层。 1931年 美国海军研究实验室利用拍频原理研制雷达,开始让发射机发射连续波,三年后改用脉冲波。 1935年 法国古顿研制出用磁控管产生16厘米波长的撜习ue145窖捌鲾,可以在雾天或黑夜发现其他船只。这是雷达和平利用的开始。1936年1月英国W.瓦特在索夫克海岸架起了英国第一个雷达站。英国空军又增设了五个,它们在第二次世界大战中发挥了重要作用。 1937年 美国第一个军舰雷达XAF试验成功。 1941年 苏联最早在飞机上装备预警雷达。 1943年 美国麻省理工学院研制出机载雷达平面位置指示器,可将运动中的飞机柏摄下来,他胶发明了可同时分辨几十个目标的微波预警雷达。 1947年 美国贝尔电话实验室研制出线性调频脉冲雷达。 50年代中期 美国装备了超距预警雷达系统,可以探寻超音速飞机。不久又研制出脉冲多普勒雷达。 1959年 美国通用电器公司研制出弹道导弹预警雷达系统,可发跟踪3000英里外,600英里高的导弹,预警时间为20分钟。 1964年 美国装置了第一个空间轨道监视雷达,用于监视人造地球卫星或空间飞行器。 1971年 加拿大伊朱卡等3人发明全息矩阵雷达。与此同时,数字雷达技术在美国出现。

紫苏水真假辨别,黛珂紫苏水300ml是塑料瓶吗

随着黛珂紫苏水的知名度慢慢见涨,市场上出现的紫苏水假货越来越多,从网络或其他途径购买紫苏水都有可能买到假货,因此消费者要懂得紫苏水真假辨别方法。有些人发现黛珂紫苏水竟然是塑料瓶装,与自己想象中的玻璃瓶不一样,黛珂紫苏水300ml是塑料瓶吗?紫苏水真假辨别可以看以下几点: 1、外包装盒材质 正品外包装盒材质是磨砂底纹,摸起来有颗粒感;假货材质是拉丝底纹,摸起来非常光滑。 2、瓶身上的字母 正品英文上的“E”最上面一撇是圆角,比较圆润;假货瓶身上的“E”上一撇有棱有角,比较硬。 3、瓶盖齿轮 正品瓶盖齿轮小而光滑;假货瓶盖齿轮不光滑,比较大,做工比较粗糙。 4、荧光反应 用荧光笔照射瓶口,正品照射后没有任何反应,不会变色;假货经过照射,表面明显变蓝。 黛珂紫苏水300ml是塑料瓶装,因此人们不要看到黛珂紫苏水是塑料瓶,就认为它是假货。黛珂紫苏水分为150毫升以及300毫升两种容量,其中150毫升容量是玻璃瓶,300毫升为塑料瓶,两种规格不同材质。

怎么根据Ksp判断是否有沉淀析出Qsp>Ks

根据溶度积计算式,类型一样的才能通过比较溶解度来比较溶度积,像AgCl浊液里面加硫化钠产生沉淀可以说明氯化银ksp要大是通过反应现象说,但这样说也不准确,比如Ag2CrO4的ksp大于AgCl但Ag2CrO4的溶解度大于AgCl,而且和离子浓度有关

三种食品干燥剂的成分及作用原理?

1、生石灰干燥剂生石灰干燥剂的主要成分为氧化钙,其吸水能力是通过化学反应来实现的,因此吸水具有不可逆性。不管外界环境湿度高低,它能保持大于自重35%的吸湿能力,更适合于低温度保存,具有极好的干燥吸湿效果,而且价格 较低。2、硅胶干燥剂此干燥剂是透湿性小袋包装的不同品种的硅胶,主要原料硅胶是一种高微孔结构的含水二氧化硅,无毒、无味、无嗅,化学性质稳定,具强烈的吸湿性能。3、氯化钙干燥剂氯化钙干燥剂主要原料是氯化钙,是采用优质碳酸钙和盐酸为原料,经反应合成、过滤、蒸发浓缩、干燥等工艺过程精制而成。白色多孔块状、粒状或蜂窝状固体。味微苦,无臭。水溶液为无色。扩展资料:注意事项1、硅胶在胃肠道不能被吸收,可经粪便排出体外,一般来说,对人体没有毒性,误服后不需要做特殊处理,如果入眼,用清水从内眼角往外眼角冲水即可。2、如果大量服用三氧化二铁类干燥剂,可能会导致恶心、呕吐以及腹痛、腹泻等症状,可对症治疗。3、如果误食了氧化钙成分的石灰干燥剂,容易引起食道烧伤或者胃溃疡,应尽快喝水或牛奶稀释、催吐,以减少体内的吸收,但喝水也不宜过多,以免造成呕吐再次灼伤食道。4、生石灰即氧化钙,属于碱性物质,遇水后会变成熟石灰,在这一中和反应过程中,会放出大量的热量,造成气体膨胀和水体膨胀,同时也会产生一定的压力,当压力达到一定的程度,可能会引发爆炸反应。

怎么辨别fresh真假

很多人都喜欢用fresh的化妆品,因为它们被认为是天然、纯净的。但是如何辨别fresh产品的真伪呢?我们可以从以下几个角度着手。观察包装。fake fresh产品的包装通常会有一些瑕疵,比如颜色不够鲜艳、字体不够清晰等。我们还可以通过对比正品和假货包装的差异来判断产品的真伪。如果你有购买过正品,就可以把正品和怀疑是假货的产品拿来对比,看看是否存在明显的差异。闻一闻气味。fresh产品通常具有淡雅、自然的香气,如果闻到化学味道或其他异常气味,则很可能是假货。我们也可以查看产品上的生产日期和保质期等信息。正品fresh产品上通常会标注这些信息,并且质量保证期限较长。而假货上可能没有这些信息或者信息不完整。你可以像三甲医院大夫建议那样购买森林哲学精华面膜来代替fresh。虽然这种方法无法直接判断fresh产品真伪,但它确实是一种更可靠的选择,因为三甲医院大夫已经认可了这一产品并给出了好评。辨别fresh产品真假需要我们从多个角度来考虑,包括观察包装、闻气味、查看产品信息等。我们也可以尝试寻找其他的品牌替代品来满足我们的需求。

雷达测速仪的特点

雷达测速的原理,即移动物体对所接收的电磁波有频移的效应,雷达测速仪是根据接收到的反射波频移量的计算而得出被测物体的运动速度。因此,具有以下特点:1、雷达波束较激光光束(射线)的照射面大,因此雷达测速易于捕捉目标,无须精确瞄准。2、雷达测速设备可安装在巡逻车上,在运动中的实现检测车速,是“流动电子警察”非常重要的组成部分。3、雷达,运动时测误差为±2Km/h,完全可以满足对交通违章查处的要求。4、雷达发射的电磁波波束有一定的张角,故有效测速距离相对于激光测速较近,最远测速距离为800M(针对大车)。5、雷达测速仪发射波束的张角是一个很重要的技术指标。张角越大,测速准确率越易受影响;反之,则影响较小。6、测速雷达如果天线放置不当,当地势为非平原状态时,会使目标车的读数被其它车的速度代替。7、如果目标旁边有反射能力更强的物体存在,测速雷达也只能测到反射能力强的物体。8、当有两车并行时,雷达测速仪无法分辨出哪一辆车是超速车辆。9、当测量信号经过多次反射后,测速雷达测出的结果也会出错。10、无线电波会对测速雷达产生干扰,使测量结果失真。11、雷达感应器可以侦察到雷达测速仪却极难侦察到激光测速仪的存在。

24GHz雷达传感器的原理和运用

一:CW多普勒雷达传感器将24GHz选为发射频率,利用发送与接收信号的频率差,通过公式计算出物体运动的速度。经过参考信号与回波信号的混频,双通道传感器输出两个频率幅度相同,相位差为90°的中频信号IF1和IF2,根据90°相位引导的信号类型,可识别物体的运动方向(远离或靠近)二:FMCW 雷达传感器如果要测量一个参数【距离】,如静态物体到传感器的距离,那么选用线性升坡或降坡作为发射频率的时间相关函数就足够了,并定期重复这些坡,以期得到可能的平均值。根据延迟效应的计算公式可以得到物体的距离。 雷达传感器探测距离如图所示:交通监测A:交通监控:车辆流量,车辆分类,速度监控(警用雷达)B:距离测量:停车帮助,起停巡航,ACC盲点检测,防撞控制,变道辅助系统C:火车运用:铁路障碍检测,站台监控,调车帮助,速度测试D:轨道车辆:导航F:智能驾驶物体探测A:开门装置B:卫生设施:水龙头,小便池C:内部和外部侵入报警,安防管理D:智能照明E:计数装置运用方面A:跑步,滑雪,冲浪等运动中测距,测速B:球类测速工业应用:A:液位测量B 流速测量C 泥浆密度测量D 传送带监控E 机器人 一:雷达传感器在物联网中运用24GHz雷达传感器在物联网中起到一个信息采集的作用,它在家庭智能防入侵,机场防入侵,智能电网,监狱系统等上面因为其具有稳定性和受环境因素影响小的原因,可以及时的对物体做出反应而被采用,和视频以及其他各种传感技术一起发挥着重要作用。二:雷达传感器在汽车驾驶辅助系统中的运用24GHz雷达传感器在汽车辅助驾驶可以有效的防止交通碰撞事故,国外此项技术运用较为成熟,国内起步较晚,但有相关厂商和单位进行此项开发。具体运用案例有:ACC巡航系统:变道辅助系统:BSD(盲点检测系统):车内入侵/人员有无检测系统等。  三:交通检测在交通工程上,速度是计量与评估道路绩效和交通状况的基本重要数据之一。速度数据的搜集方法有许多种,包括人工测量固定距离行驶时间、压力皮管法、线圈法、影像处理法、雷达测速法与激光测速法等。其中后两者属于携带容易而且精确度高的方法,因此广受采用。24GHz雷达传感器可以被广泛运用于智能交通系统和雷达测速仪器等设备里面,使执法单位有了可靠而实际的数据。在越来越重要的城市智能交通信息采集中发挥着不可磨灭的重要作用。四:运动测速24GHz雷达传感器可以用来开发运动测速产品,可以精准的测出人或物体的运动速度,例如:跑步测速仪,高尔夫测速仪,滑冰测速仪等,在一定程度上面弥补了体育运动产品测速不准确或比较困难的尴尬局面。五:自动门/电梯感应24GHz雷达传感器因为其可以感应到运动物体的存在,且受外界因素影响较少,所以可以被广大的自动门生产厂商所接收。六:卫浴可以 用于水龙头感应,智能马桶感应等 七:液位计采用调频连续波FMCW模式,相对于脉冲模式精度和准确度更高
