中国工业推动数字化转型 中小企业大有可为，网络化、协同制造、服务型制造等新模式、新业态不断涌现。这次疫情带来了0所未有挑战的同时，也让社会各界更清楚意识到数字化转型的价值。 尤其0近，中国提出加快5G网络、数据中心等“新基建”推进进度，毋庸置疑将加速数字化发展。而数字化转型涉及到软件开发、软硬件融合、系统集成以及数据分析、智能化控制等多个环节，并且还要落地到具体应用场景，这需要产业链上下游企业共同努力，非0家之力可以完成。 在此过程中，不仅仅是大企业，中小企业也是至关重要的推动力量。但中小企业面临技术和市场局限、资金不足、人才紧缺等瓶颈，如何将其纳入数字化浪潮是无法规避的0大挑战。

 

施耐德电气全球执行副总裁、中国区总裁尹正 中小企业大有可为 对所有企业而言，在数字转型过程中，无论是5G、云计算、AI，还是IT技术，要与具体的应用场景相结合。但0些通用技术很难被拿过来直接使用，也就是存在IT如何融合OT的问题，这实际上是数字化转型的0大挑战之0。同时，数字化急需解决的0个问题，是如何利用已积累的数据提升产品质量、生产的灵活性和生产运营效率。 此外，尽管大企业对某些领域所需的工艺及应用场景有深刻理解，但很难覆盖所有需求，有着更高灵活性的中小企业则能够发挥更大0势。很多中小企业通常深耕于某些特定领域，不断提供纵深的服务，从而获得了挖掘更深层次技术运用和开发的机会，这也是推动数字化0重要的驱动力之0。 例如，拉链生产企业属于传统劳动密集型行业，由于自动化水平较低，不少染色生产线上还依靠人工来进行上下料等操作。成都瑞克西自动化技术有限公司为了帮助客户在染色加工环节提升产品质量和生产效率，希望借助数字化手段实现订单管理、排产、立库管理、质量检验、远程运维等多种定制化功能。 而这种小而专的需求，对于0直从事拉链染色生产线研发和生产的瑞克西来说，更容易实现。瑞克西基于施耐德电气EcoStruxure 机器解决方案开发出“拉链染色调度系统”，使得整体生产增效10%以上、节能20%。

此外，瑞克西的业务模式也因此有了改变，除了向客户提供用于拉链染色的全套数字化产线设备外，还可以把设备放在客户车间对拉链染色，实现了从出售“设备”到出售“机器小时”的转变，开启了数字化运营过程。 “入圈”共谋发展 通常情况下，由于缺乏技术、资金以及生态支持，中小企业很难自发开发应用场景，并实现规模化复制。中小企业需要0个兼具软硬件能力、充分了解市场，且拥有开放生态的中间平台，帮助自己提升技术实力，从而有效解决问题，0终形成数字化的解决方案，从整体上推动行业数字化转型。 施耐德电气基于工业物联网的EcoStruxure正是这样0个推进数字化转型的平台。

    模拟量输入/输出接口0般用来感知传感器产生的信号。这些接口可用于测量流量、温度和压力，并可用于控制电压或电流输出设备。这些接口的典型量程为-10～+10V、0～+11V、4～20mA或10～50mA。0些制造厂家在PLC上设计有特殊模拟接口，因而可接收低电平信号，如RTD、热电偶等。0般来说，这类接口模块可用于接收同0模块上不同类型的热电偶或RTD混合信号。

    在选择0台PLC时，用户可能会面临0些特殊类型且不能用标准I/O实现的I/O限定（如定位、快速输入、频率等）。此时用户应当考虑供销厂商是否提供有有助于限度减小控制作用的模块。有些特殊接口模块自身能处理0部分现场数据，从而使CPU从繁重的任务处理中解脱出来。2021 年“十四五规划”开局，中国数字化转型的落地进入关键的“拐点”阶段，与此同时，在“ 3060 碳目标”的要求下，中国制造企业转型升级迫在眉睫。然而，落实到具体应用，IT 与 OT 的数字融合问题依旧是横亘在制造企业转型面0的“大山”，数据价值难以充分发挥。

Industrial control refers to industrial automation control, which is mainly realized by the combination of electronics, electricity, machinery and software. That is industrial control, or factory automation control. It mainly refers to the use of computer technology, microelectronics technology and electrical means to make the production and manufacturing process of the factory more automated, efficient, accurate, controllable and visible.



Industrial control computer is a general term for tools that use bus structure to detect and control the production process and its electromechanical equipment and process equipment. It has important computer attributes and characteristics, such as computer CPU, hard disk, memory, peripherals and interfaces, real-time operating system, control network and protocol, computing power, friendly man-machine interface, etc. The main categories of industrial computers include IPC (PC bus industrial computer), PLC (programmable control system), DCS (distributed control system), FCS (Fieldbus System) and CNC (numerical control system). 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 was tested on the production line of General Motors with remarkable results. Later, PLC technology was carried forward 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、 Used to realize various motion control



PLC controller is a digital electronic device with microprocessor. It is a digital logic controller used for automatic control. It can load control instructions into memory at any time for storage and execution. The programmable controller is composed of internal CPU, instruction and data memory, input and output unit, power module, digital analog and other units. PLC controller can be used for the control of 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 module to connect position sensor and actuator. Now, special motion control module is generally used, such as single axis or multi axis position control module that can drive stepper motor or servo motor.



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, flow and so on. 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 value stored in the memory to complete certain control operations, and can also be transmitted to other intelligent devices by 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 related 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 the industrial control and Internet of things markets



Three characteristics of PLC technology in the future



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. The characteristics of PLC products are control and data processing. While meeting the functions, the technological requirements are more refined.



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



3. Diversified PLC technology: 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 technology will also increase.



China's PLC market has great potential



Nowadays, 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 domestic enterprises with certain influence have also been born, such as Delta, Huichuan, Hexin, Yiwei, Kewei and Lishi. According to relevant data, the size of China's PLC market was 10 billion yuan in 2017, 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.

Cavitation behavior of low pressure air separation liquid oxygen pump

In the full low pressure air separation plant, sometimes it is found that the outlet pressure of the centrifugal liquid oxygen pump suddenly drops, and the liquid oxygen cannot be discharged, and the liquid oxygen pump cannot continue to work. This phenomenon is often called "air entrainment". This phenomenon of "air entrainment" of liquid oxygen pump is called "cavitation" in professional terms. 2 liquid
