CMOS，互补性氧化金属半导体。和CCD一样，同为在数码相机中可记录光线变化的半导体。CMOS的制造技术和一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 工业相机一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，既可以拍摄一般物质，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，00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，前一张可能被迫丢弃，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)并不是一台简单的相机，而是一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一相机内，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 分析仪的优势之一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一些科学家撰写的论文中发表。



相比CRDS技术，LGR 0利的0四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发后，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“ABB0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0球0一款高精度轻型无人机载温室气体分析系统。

Everyone who studies electronics knows that PLC is a very important device and a relatively difficult technology. It is a digital operation electronic system specially designed for application in the industrial environment. It is the basis for realizing industrial automation and Internet of things control. It has a very broad application prospect in the future.

PLC technology originated in the United States



PLC technology originated in the United States. General Motors of the United States was the first to apply PLC. In the 1960s, when they adjusted the factory production line, they found that the relay and contactor control system was difficult to modify, large in size, noisy, inconvenient to maintain and poor in reliability. Subsequently, the American digital equipment company developed the first programmable controller, which has achieved remarkable results in the production line of general motors. Later, PLC technology was developed in Japan and Europe, and programmable controllers were successfully developed in Japan and Germany. In 1974, China also began to study programmable controllers and widely used in various fields.



PLC first replaced the mechanical switch device, and then the function of PLC gradually replaced the relay control board. Modern PLC has more functions, and its purpose extends from single process control to the control and monitoring of the whole manufacturing system.



Application of PLC technology in industrial automation, Internet of things control and other fields



At present, PLC technology is widely used in industrial automation, automotive electronics, transportation, Internet of things control and other industries. Its role in these fields can be roughly divided into four categories.



1、 For various motion control



PLC controller is a kind of digital electronic equipment with microprocessor. It is a digital logic controller used for automatic control. It can load control instructions into memory for storage and execution at any time. The programmable controller is modular composed of internal CPU, instruction and data memory, input and output unit, power module, digital analog and other units. PLC controller can be used to control circular motion or linear motion. Nowadays, almost all the main PLC controller products have motion control function. It is used in various machinery, machine tools, robots, elevators and other occasions.



In terms of control mechanism configuration, in the early days, it was directly used for switching value i/o modules to connect position sensors and actuators. Now, special motion control modules are generally used, such as single axis or multi axis position control modules that can drive stepper motors or servo motors.



2、 Realize industrial process control



As an industrial control computer, PLC controller can compile various control algorithm programs to complete closed-loop control. In industrial process control, PLC is mainly used for closed-loop control of analog parameters such as temperature, pressure and flow. All large and medium-sized PLCs have PID modules. PID regulation is a regulation method commonly used in general closed-loop control systems. At present, many small PLC controllers also have this function module.



3、 Realize relevant data processing



Modern PLC controller has the functions of mathematical operation, data transmission and conversion, and can complete data collection, analysis and processing; These data can be compared with the reference values stored in the memory to complete certain control operations, and can also be transmitted to other intelligent devices using the communication function. In large-scale control systems, such as unmanned flexible manufacturing system, PLC controller is one of the core components.



4、 PLC communication and Internet of things



As the general trend of industrial Internet of things, the relevant technologies of PLC communication and Internet of things will be popular in the future. General PLC controller communication includes communication between PLC controllers and communication between PLC controller and other intelligent devices. With the development of industrial control automation, all PLC controller manufacturers attach great importance to the communication function of PLC controller, and have launched their own network systems. New PLC controllers have communication interfaces, which is very convenient for communication.

PLC technology has great potential in industrial control and Internet of things market



Three characteristics of future PLC Technology



1. Miniaturization and integration are getting higher and higher: with the requirements of the market for miniaturization and integration, PLC technology is more integrated into industrial, automotive, communication and other products. PLC products are characterized by control and data processing. While meeting the functions, the process requirements are more refined.



2. Intelligent PLC technology: with the development of AI technology, more products are endowed with intelligent functions, and PLC is no exception. For example, the intelligent i/o module of PLC used in industrial control and the intelligent temperature control module used in automobiles will have more application scenarios in the future.



3. Diversified PLC technologies: including PLC related programming languages and tools. With the deepening of application scenarios, one or several programming languages cannot achieve all functions, customized PLC products will increase, and PLC modular technologies will also increase.



Great potential of PLC market in China



Today, PLC technology is developing rapidly. According to statistics, there are more than 300 PLC manufacturers and more than 500 PLC products in the world. The United States, Europe and Japan are the main production places, with a market share of more than 60%. There are A-B companies, general electric and Modicon in the United States; Siemens and AEG in Germany; Te company in France; Mitsubishi, Omron and Panasonic in Japan are all famous PLC suppliers.



In recent years, with the attention of the state and enterprises, China's PLC industry has maintained rapid growth, and there have also been some influential enterprises in China, such as Delta, Huichuan, Hexin, Yiwei, Kewei and Lishi. According to relevant data, the scale of China's PLC market in 2017 was 10 billion yuan, and it is expected to maintain a growth rate of 20% in 2018. Domestic PLC products have very good cost performance and service, which has brought them a good reputation and market.
