Brief introduction

Digital factory is the system that is based on data to move, comprise element to work in coordination each among them, in order to optimize the operation efficiency of factory workshop. In some way, it is OK with analogy of human body photograph. Sensor acts as eye and ear, make central controller (or cerebrum) can understand surroundings. Carry out implement appropriative muscle, adjust according to needing to make. Factory join network is equivalent to deploy be in of the whole body neurological, and the skin represents pair of data to protect crucial network security technology.

The advantage of digital factory

Before the component that discusses digital factory, we summarize its advantage above all. The advantage of digital factory basically is reflected to improve productivity, make manufacturing industry then pattern happening changes. The new understanding that comes from digital factory ecosystem conduces to for real time decision-making provide information. Accordingly, product quality gets ameliorative, integral operation efficiency is taller, realize the pull current Cheng that can last more finally. 50% what the sources of energy that industrial department wastes takes global total specific power consumption about, 1 to with clean 0 discharge the manufacturer that is a target for, digital interconnection factory is this changing core. Besides but besides durative advantage, digital factory still provides flexibility and capability of real time configuration, with answering Protean consumer demand quickly. For example, in domain of medical treatment health, people grows increasingly to the demand of personalized medical apparatus and instruments, if according to the patient individual body structure measures a body,custom-built 3D prints articulatory and embedded content to wait. As the factory the design becomes more modular, manufacturing unit becomes smaller and adaptability is stronger, working flow can be arranged in real time and change, promote production rate thereby, support this locality that has cost competition ability is carried out to produce flow in Europe and North America.

Data — the lifeblood of digital factory

Come from entire plant the real time of many origin and blame real time data, must be in intelligent brim (the place that generates data) undertake fast and reliable analysis, have pool in central level, announce thereby the complete picture that whole factory runs. The operation that reachs from these data has an insight into crucial to releasing the latent capacity of overall moving efficiency of the factory adequately.

Sensor — of digital factory ” information “

The factory needs deploy more sensor and pass all sorts of detecting (for example temperature, pressure, discharge, adjacent spend and oscillatory) will get necessary data. Feel to last, measure, unscramble plant property, plant need nicety is measured and detect technology. IO-Link? The technology makes sensor becomes intelligence is changed. Pressure sensor can judge pressure to whether exceed place to need threshold value in this locality, what need to offer single bit to controller only accordingly is Boer model variable (be or deny) , it represents one digit to occupy only, is not the complete number value that states real pressure measures an outcome. This locality is changed decision-making can save communication and processing time, realize efficient distributed control.

Carry out implement — the muscle of digital factory

Carry out implement the anonymous hero that is digital factory normally, be equivalent to the muscle in human body, crucial to completing the work. Carry out implement use at controlling valve, piston and other machine. They are OK and accurate the flow that controls a fluid, ensure the stock of will true measure carries every share of flow.

Sensor and carry out implement need to be able to bear or endure the ambient conditions that accepts application. Factory environment is very harsh, existence high temperature, electromagnetism (aiguille of transient state of voltage of EMC) radiate, power source, mechanical vibration is waited a moment. Detect to these brims and drive system, power transmission is element of another crucial consideration. Mix as sensor carry out implement smaller and smaller, taller and taller also to the performance demand of power transmission, the precision that at the same time signal collects and quality also rise ceaselessly. This needs the power source of efficient, low noise, small size to manage a solution. Suffer normally to the space bounds design, this kind of solution is crucial. If did not suit specific detect the technology of necessary power source of the requirement, the real time that cannot realize digital factory can configure an advantage.

Brim intelligence and central intelligence — the cerebra of digital factory

In view of digital factory requirement brim equipment has the intelligence of more function and higher level, equipment itself must undertake more computation and analysis, change in order to realize this locality decision-making. To achieve autonomy of this kind of brim, artificial intelligence of need this locality (AI)/ machine learns (accelerator of ML) engine, low power comsumption, older memory and processing capability. Sensor confluence is the brim intelligence of another kind of type, the data that comes from sensor of many different types among them is OK and synchronous union in order to appear more accurate measure an outcome — this is to use what place cannot realize any individual sensor. Have the aid of is new-style high accuracy and tall bandwidth ADC, individual sensor front can be used at monitoring many sensor component, save space and power comsumption thereby. Technology of AI small controller makes nerve network can move with exceeding low power comsumption, and emitter of low power comsumption can enhance long-range processing factory (be intelligent factory normally is outspread) diagnostic ability.

Join — of digital factory neurological

Although brim equipment has autonomy, but to manufacturer, should extract from inside a large number of available data valuable and can improve productivity have an insight into information, transmit, the capacity that analyse these data and will be iformation flow to incorporate inside its and factory is crucial. This need low defer, have time limit, low power comsumption, dovish industrial join technology. 10BASE-T1L is standard of layer of physics of net of a kind of aether (IEEE 802.3cg-2019) , aim to pass with spot equipment (sensor and carry out implement) build without seam aether net join to improve plant operation efficiency significantly, change process automation industry.

Graph 5. The IT/OT inside digital factory is shirt-sleeve

In current plant, IT (IT) network deploy is in the office / enterprise layer class. Analysis of storage of data of the attention on IT network tradition, data and business use the work such as the program. These are very important, but normally the data switch of unlike factory workshop asks to time in that way very slashing. The network that runs product line in factory workshop calls operation skill (OT) controls a network. In network of this kind of control, the likelihood is put in many different production unit or machine, the ability that they correspond each other normally finite. The concept of IT/OT network confluence in digital factory changed all these. It provides an unified factory network, all equipment, machine and robot join be in the network or undertake interrelating, use same language. Every IP can find location equipment can real time or correspond close to real time ground, and can become independent undertake configuration at the other equipment on the network. The crucial support technology of network of factory of this kind of shirt-sleeve number includes: Industrial aether net, time is sensitive network (TSN) , Ethernet-APL (advanced physics layer) with IO-Link. All equipment use the 2nd same language, the IT that because can use identical control and network management system come this now,controls a network and OT part, the time that won’t affect operation network at the same time is sensitive discharge. Time key discharge and blame time key flow is very enormous, the requirement upgrades network in order to increase bandwidth, ensure the data that does not have defer is transmitted, this product quality to improving a production factory and operation efficiency are crucial. The confluence of OT and IT releases almost infinite patulous opportunity.

The network is safe — the skin layer that protects data of authentic number factory

Rise as what interconnection each other knows extent, intelligent factory environment reveals personnel, technology, flow and intellectual property under network menace, because this need enhances data security,protect. To answer safe challenge, digital factory earnestly needs to develop safety guiding, safe software the function such as newer, safe transmission attestation and hardware accredit root. A when protect network security main field is pair of attempt join undertake identity test and verify to every new facility of the network. Whether is this includes to inspect this facility first quality goods, it is quality goods only ability accredit undertakes network general affairs is handled to it. Like facility status test and verify, safety guiding also must be had, come from the software of authentic origin in order to ensure spot equipment is carried out only, use fair key to add secret technology to come the digital sign one’s name of firmware of test and verify.
