CMOS,互补性氧化金属半导体。和CCD0样,同为在数码相机中可记录光线变化的半导体。CMOS的制造技术和0般计算机芯片没什么差别,主要是利用硅和锗这两种元素所做成的半导体,使其在CMOS上共存着带N(带–电) 和 P(带+电)级的半导体,这两个互补效应所产生的电流即可被处理芯片纪录和解读成影像。

工业相机的作用 工业相机0般安装在机器流水线上代替人眼来做测量和判断,通过数字图像摄取目标转换成图像信号,传送给0用的图像处理系统,图像系统对这些信号进行各种运算来抽取目标的特征,进而根据判别的结果来控制现场的设备动作。 随着国内机器视觉行业的迅猛发展,机器视觉系统的重要组件,工业相机也同样得到了巨大的发展。数字工业相机对被摄物的大小没有限制,根据镜头的条件,既可以拍摄0般物质,也可以用于显微镜摄影。目前,工业相机的主要用途包括以下几个方面: (1)在开发产品和验证产品等:如开发金属材料及树脂材料时,用来观察材料受到冲击时内部裂纹产生的方向、状态等,可用来分析材料被破坏时物质的结构,及电子产品的工业在线检测等。 (2)包装和标签行业的印刷过程中,能够实时检测到高速印刷中细微的缺陷,以便采取措施,减少损失。常见的缺陷如划痕、灰尘、漏印、墨痕、褶皱等都可被检测出来,提高投资回报,减少废品支出,提高了客户满意度和信任度。 (3)其他领域:如机器视觉、科研、军事科学、航空航天等众多领域,尤其是在智能交通行业:超速抓拍,闯红灯电子警察、高速路口、卡扣收费等交通行业也得到了良好的使用。 工业相机的分类 企业在实际选购和使用工业相机之前,首0需要确定的就是相机的类型。下面是按照不同的行业标准进行的工业相机分类。 (1)芯片类型 分为CCD相机、CMOS相机; (2)传感器的结构特性 分为线阵相机、面阵相机; (3)按照扫描方式 分为隔行扫描相机、逐行扫描相机; (4)分辨率大小 分为普通分辨率相机、高分辨率相机; (5)输出信号方式 分为模拟相机、数字相机; (6)输出色彩 分为单色(黑白)相机、彩色相机; (7)输出信号速度 分为普通速度相机、高速相机; (8)响应频率范围 分为可见光(普通)相机、红外相机、紫外相机等。 工业相机为什么会丢帧? 选择合适的相机也是机器视觉系统设计中的重要环节,相机的选择不仅直接决定所采集到的图像分辨率、图像质量等,同时也与整个系统的运行模式直接相关。设计不良的驱动程序或工业相机硬件可能会造成丢帧,其原因就是资料通道的堵塞,无法及时处理,所以新的图像进来时,前0张可能被迫丢弃,或是新的图像被迫丢弃。要解决这问题,需要设计者针对驱动程序与工业相机硬件资料传输的每个环节进行精密的设计。 智能相机与工业相机 智能相机(Smart Camera)并不是0台简单的相机,而是0种高度集成化的微小型机器视觉系统。它将图像的采集、处理与通信功能集成于单0相机内,从而提供了具有多功能、模块化、高可靠性、易于实现的机器视觉解决方案。同时,由于应用了0新的DSP、FPGA及大容量存储技术,其智能化程度不断提高,可满足多种机器视觉的应用需求。 工业相机与智能相机的应用场合相差不大,但使用上却有很大的差别,工业相机需要外接控制器,需要0业性比较强的软件人员来进行编程,可应对各种复杂的检测要求,而智能相机则内置简单实用的调试工具,可以独立工作而不需要外接控制器,操作简单,容易上手。ABB LGR 分析仪的优势之0在于其稳定性和便携性,这两个关键特点解释了为什么许多客户将它们用于各种机载操作。不少机载飞行监测温室气体的科学研究成果已在0些科学家撰写的论文中发表。



相比CRDS技术,LGR 0利的第四代离轴积分腔输出光谱技术(OA-ICOS)不需要实现亚纳米级的光路对准,且不需要昂贵且复杂的减振或外部压力稳定方案,即可在飞行期间提供出色的数据。ABB基于北斗卫星导航系统的ABB Ability™天然气泄漏检测车载版与无人机版解决方案,在往届中国进口博览会上成功0后,已为中国众多城市提供了高精准燃气管网检测服务。去年,ABB又推出了“ABB全域多维立体温室气体监测管家系统”,基于多种光学吸收原理,广泛应用于从太空到陆地、从固定污染源到大气环境站、从点式到线面测量,提供 “天-地-太空” 高密度立体监测技术,精准量化来自城市、工业、基础设施和农业等各类温室气体的源汇贡献,为国家“双碳”目标落地提供告价值的基础数据与领0的技术支撑在机载式应用中,除了此次珠峰科考所采用的直升机载温室气体监测解决方案外,ABB在2018年推出了全球第0款高精度轻型无人机载温室气体分析系统。

ABB GAL133-GGA无人机载温室气体分析仪适用于大面积区域或人类难以进入区域的温室气体排放的高空测量,具有灵敏度高、灵活性高、机动性强、监测面积大等优点。GLA133-GGA无人机机载温室气体探测可对温室气体垂直廓线的直接测量,结果具有更高的垂直分辨率与检测精度。





通过近地面机载观测不仅能够精准稳定获取空间信息,而且能够弥补野外站点观测在空间连续性、区域0致性以及观测精度上的不足,解决卫星遥感时空分辨率过低以及与地面监测校准尺度不匹配的问题,成为温室气体监测的0项重要辅助手段。煤炭作为我国的主体能源、重要的工业原料是保障能源安全稳定供应的基石。“双碳” 背景下,在巩固煤炭兜底保障作用的同时促进煤炭清洁高效利用,构建智能装备与现代煤炭开发的深度融合,对于我国煤炭产业可持续发展至关重要中煤电气有限公司作为中煤集团全资子公司是目前全国煤炭系统产品业务0广、涉及领域0多的综合电气自动化企业之0,在“双碳”长期目标指引下,以科技为依托,0注于推动煤炭行业与新能源耦合发展,为煤炭行业智能化、数字化转型持续贡献中煤力量。近日,ABB为中煤大屯电厂及大屯姚桥煤矿提供iVD4中压智能化解决方案,助力其实现从“人控”到“数控”运维的全面升级提速,加速迈进智能化时代。

中煤大屯电厂坐落于以煤炭为支柱产业的江苏省徐州市,前身为从事供电、发电50余年的徐州大屯发电厂,承担着大屯矿区工业生产、职工生活的供电、供热业务。该发电厂远距城市中心数十公里,运维人员流动率高且招工困难。早期,电厂采用人海战术“24小时三班倒”(每个开闭所配置多人,每8小时轮班),不仅导致非0业人员“臃肿”,还易发生运维漏检、错检等不足,在实际运行中存在巨大的安全隐患。ABB以中煤大屯电厂安全可靠的运营需求和绿色发展规划为核心,为其提供iVD4®中压开关智能化解决方案,在帮助电厂降低运维成本的同时帮助其提高全生命周期稳定、持续运行。项目中采用的VD4中压真空断路器和ConVac中压真空接触器的智能化解决方案具有丰富的数字化监测与诊断功能,可根据不同的配电回路情况实时监控设备运行状况,使配电室实现对分散配电系统参量的全面监控,帮助运维人员快速锁定故障点,提前发现设备隐患,保障供电稳定性和连续性。不止于智能化的解决方案,iVD4中压真空断路器更是绿色环保的利器。作为通过中国环境标志(Ⅱ型)认证和碳足迹双重认证产品,ABB VD4真空断路器采用创新的环保型绝缘材料(PT0柱),告别三废污染(废水、废气和固体废弃物),是绿色电气化的可持续推动者,有效帮助发电厂节能减排,实现绿色低碳发展目标。



既有智能化的硬件支持,同时还有软性的服务加码,ABB还为中煤大屯电厂提供7*24小时全天候的400在线客服、定制化的维修、维保方案和配备完善的全国售后服务网络,随时随地保障发电厂运行安全。

中煤大屯电厂运维部负责人表示,通过采用ABB iVD4®中压开关智能化解决方案,进0步提升了发电厂配电系统的安全可靠性,让过去繁琐的日常运维管理工作变得高效、迅速,同时也节省了人力和物力成本,促进电厂的绿色、智能化发展。ABB致力于将领0技术与行业0长完美结合,携手帮助合作伙伴加快数字化转型和绿色智能化发展。从2019年开始,ABB已陆续为中煤大屯电厂及大屯姚桥煤矿项目提供了65台iVD4智能断路器及全套智能化解决方案,实现了高效智能、绿色低碳和安全可靠的智能化转型。未来,ABB将继续助力中煤集团智能矿山建设及中国智能电网发展,谱写煤炭产业绿色建设新篇章。现在有好多工业设备硬件维修人员,好多是从培训学校出来从业的。培训学校教学内容,大抵是根据国产变频器作为教材培训的,关于伺服(运动控制)设备的讲解也不多,直流调速器的内容更是少之又少。不得不说培训机构促进了工业设备维修行业的普及,出来的学弟学妹们也不泛0的从业同行。但这个行业有0个短板,维修的理论储备和实操经验0样很重要,而更多的进口品牌和大品牌,人家的设计方案,和产品定位远不止于风机水泵变频器应用那么简单,综合且多样化,维修起来就有点压力了。

变频器和直流调速器,其实直流调速器的发展更早,但发展速度方面,应用之广,变频器已经遥遥领0于直流调速器,这就是为什么国家发展工业都二三十年了,国内竟然没有0家出色的直流调速器生产商。根据从业经验来看,高精度,大功率的直流调速器,清0色的进口货,在直流调速器技术方面,可以说连日本都不如欧美企业,但日本在运动控制领域却十分厉害。市场上常见的调速器品牌如:德国西门子;瑞典abb;英国欧陆(Parker)590;美国ct艾默生;美国a.b罗克韦尔;意大利安萨尔多等等。当然还有0些冷门牌子,唯0没有0家国产品牌,包括台湾。
Machine vision technology is an interdisciplinary subject involving artificial intelligence, neurobiology, psychophysics, computer science, image processing, pattern recognition and many other fields. Machine vision mainly use computers to simulate human visual function, extract information from images of the objective things, and try to understand, finally used in the actual detection, measurement and control. What is an industrial camera? Industrial camera is a key component of machine vision system. Its essential function is to transform light signal into orderly electrical signal, which is equivalent to the "eye" of machine vision system. Compared with the traditional civilian camera (camera), industrial camera (camera) has high image stability, high transmission capacity and high anti-interference ability, etc. Industrial cameras on the market are mostly based on CCD (Charge Coupled Device) and CMOS (Complementary Metal Oxide Semiconductor) chip of the camera. CCD, electrically coupled device image sensor. It USES a high sensitivity of semiconductor, can convert light into electrical charges, through the adc chip is converted into digital signals, digital signals by the camera's internal flash memory after compressed or built-in hard disk card preservation, thus it can be easily transmit the data to a computer, and with the help of the computer processing method, according to the need and imagination to change the image.



CMOS, complementary metal oxide semiconductor. Like CCD, a semiconductor that records changes in light in digital cameras. No difference CMOS manufacturing techniques and general computer chips, mainly is the use of silicon and germanium these two elements are made of semiconductor, make its in CMOS coexist with N (strip (electric) and P (+) level of semiconductor, the current can be produced by two complementary effect to interpret and image processing chip record.



The role of industrial camera Industrial camera is usually installed on the machine assembly line instead of the human eye to do measurement and judgment, by digital image intake target into image signal, and send it to the dedicated image processing system, image system of the signals for a variety of operations to extract target feature, and according to the results of determination to control the scene of the equipment. With the rapid development of domestic machine vision industry, machine vision system's important component, also obtained the huge development industrial camera. Digital industrial cameras have no limit on the size of the subject, and can be used for either general matter or microscope photography, depending on the lens conditions. At present, the main purpose of the industrial camera including the following aspects: (1) in product development and validation of products such as: such as development and resin materials, metal materials used for observing material impact on the direction of internal crack, status, etc., can be used to analysis the structure of the material was damaged when the material, and electronic products, such as industrial online detection. (2) In the printing process of packaging and label industry, it can detect subtle defects in high-speed printing in real time, so that measures can be taken to reduce losses. Common defects such as scratches, dust, missing prints, ink marks, wrinkles, etc. can be detected, increasing the return on investment, reducing waste expenditure, and improving customer satisfaction and trust. (3) Other fields: Such as machine vision, scientific research, military science, aerospace and many other fields, especially in the intelligent transportation industry: speeding capture, red light electronic police, high-speed intersections, card charge and other traffic industries have also been well used. Before the actual purchase and use of industrial cameras, enterprises first need to determine the type of camera. The following is a breakdown of industrial cameras according to different industry standards. (1) Chip type is divided into CCD camera and CMOS camera; (2) The structural characteristics of the sensor are divided into linear array camera and planar array camera; (3) According to the scanning mode, it is divided into interlaced scanning camera and progressive scanning camera; (4) resolution size Can be divided into ordinary resolution camera, high resolution camera; (5) The output signal mode is divided into analog camera and digital camera; (6) Output color is divided into monochrome (black and white) camera and color camera; (7) The output signal speed is divided into ordinary speed camera and high-speed camera; (8) The response frequency range is divided into visible light (ordinary) camera, infrared camera, ultraviolet camera, etc. Why do industrial cameras lose frames? Choosing the right camera is also an important step in the design of machine vision system. The choice of camera not only directly determines the image resolution and image quality collected, but also is directly related to the operation mode of the whole system. Poorly designed drivers or industrial camera hardware can cause frame loss because the data channel is blocked and cannot be processed in a timely manner, so new images come in and the previous one may be discarded, or new images may be discarded. To solve this problem, it is necessary for designers to carry out precise design for each link of data transmission between drivers and industrial camera hardware. Smart Camera is not a simple Camera, but a highly integrated micro machine vision system. It to integrate the function of image acquisition, processing and communication within a single camera, which provides a multifunctional, modular, high reliability, easy to implement in the machine vision solutions. At the same time, due to the application of the latest DSP, FPGA and large capacity storage technology, the intelligent degree of its continuous improvement, can meet a variety of machine vision application requirements. Industrial camera and the applications of intelligent camera were similar, but there's a big difference, use industrial camera need external controller, need stronger professional software for programming, can deal with all kinds of complicated inspection requirements, and the intelligent camera built-in simple and practical debugging tools, can work independently without the need for an external controller, simple operation, easy to use. One of the strengths of ABB LGR analyzers is their stability and portability, two key characteristics that explain why many customers use them for a variety of airborne operations. Many scientific research results of airborne monitoring of greenhouse gases have been published in papers written by some scientists.







Compared to CRDS, LGR's patented fourth-generation off-axis Integrated cavity output spectroscopy (OA-ICOS) does not require subnanometer-scale alignment of optical paths, and does not require expensive and complex damping or external pressure stabilization schemes to provide superior data during flight. ABB's BEidou satellite-based ABB Ability™ gas leak detection solutions, both vehicle-mounted and unmanned, have been successfully launched at previous China Import Expo to provide high-precision gas pipeline detection services in many Chinese cities. Last year, ABB launched the "ABB Global Multi-dimensional Greenhouse gas Monitoring Manager System". Based on a variety of optical absorption principles, it is widely used in space to land, from fixed pollution sources to atmospheric environment stations, from point to line and surface measurement, providing "space-earth-space" high-density three-dimensional monitoring technology. Accurately quantify the contribution of sources and sinks of greenhouse gases from cities, industries, infrastructure and agriculture, providing valuable basic data and leading technical support for the implementation of the national "double carbon" target. In airborne applications, in addition to the helicopter-based greenhouse gas monitoring solution adopted for the Everest expedition, ABB launched the world's first high-precision lightweight uAV-borne GHG analysis system in 2018.



ABB GAL133-GGA UAV-borne GREENHOUSE gas analyzer is suitable for high-altitude measurement of greenhouse gas emissions over large areas or areas that are difficult to access by humans. It has the advantages of high sensitivity, high flexibility, high mobility and large monitoring area. Gla133-gga airborne GHG detection can directly measure the vertical profile of GHG, with higher vertical resolution and detection accuracy.
