(zhoukaiyang, Licheng, an electronic enthusiast) on June 15, 2022, the sixth 2022 industrial control and communication technology seminar hosted by the world-famous electronic technology media was successfully held online. At this meeting, experts and leaders from well-known enterprises at home and abroad, such as Italian French semiconductor, ADI, Ti, smart, microchip, siliconlabs and so on, brought the latest technology sharing.

Microchip: Industrial IOT and microchip TSN Industrial Solutions

In the industrial control and communication technology seminar held by the electronic enthusiast network, Zhang Tianfu, the marketing manager of microchip products, shared the theme of “industrial IOT and microchip TSN industrial solutions”, and introduced and analyzed the popular industries and TSN applications in the current market, as well as the corresponding solutions.

Zhangtianfu said that the TSN network can provide Ethernet services with real-time, high reliability and bandwidth guarantee. At the same time, the TSN network can also allow the comprehensive existence of key and non key services with high real-time requirements. Secondly, TSN is based on ieee802.1 and IEEE802.3 open standards. It does not rely on any third-party vendors.

Such as Internet IP PROFINET, the existing industrial Ethernet protocols can run on the TSN network and share the TSN infrastructure. Due to the openness of TSN network. OT and it networks can be better integrated, reducing complex gateways and protocol conversion equipment, and better enabling applications such as intelligent manufacturing and edge computing.

At the same time, TSN network adopts standardized hardware and tcp/ip protocol stack, which can control the cost more efficiently in product procurement and equipment maintenance. Thanks to its high reliability, strong compatibility and low operation and maintenance cost, TSN network has been widely used in industrial control, electric vehicles and automatic driving applications.

In the industrial and automotive application markets, microchip, a chip manufacturer with more than 30 years of experience, has continued to invest in industrial Ethernet products. Moreover, microchip’s TSN technology has also reached the industry-leading level, and has launched a series of TSN solution product combinations.

For example, lan966x series low-power TSN switching chips for TSN terminals and gateway devices have built-in cortex-a7 processors, support up to 8 1g Ethernet interfaces, and rich peripheral expansion interfaces such as PCIe, USB, SPI, etc. For automotive applications, lan937x series TSN switching chips are launched. The series chips support up to 8 Ethernet interfaces, including 5 100m T1 interfaces. They have passed the rigorous ace-q100 Grade2 certification and can meet the requirements of vehicle specification applications. At the same time, microchip also speculated vsc7546tsn and vsc7549tsn series switching chips that meet industrial application standards for TSN rack and rack devices.

Of course, microchip has more advantages in the TSN field than this. In addition to providing a series of product combinations, microchip can also provide TSN protocol and application software with full stack function, high-precision 1288 time synchronization protocol and software, as well as IPv4 and IPv6 dual protocol stack support. At the same time, it can also provide a series of development tools such as complete reference design and evaluation board, so as to shorten the product development cycle of customers, accelerate the product launch and seize the market.

Silicon labs: a safe and intelligent efr32 platform to accelerate industrial automation applications

Silicon labs is a leading brand in the field of security and intelligent wireless technology. In the industrial control and communication technology seminar held by the electronic enthusiast network, huangliangjun, a field application engineer of silicon labs, shared the theme of “safe and intelligent efr32 platform to accelerate industrial automation application”.

In this seminar, huangliangjun made a detailed interpretation of the three typical applications of networked lighting, asset tracking and automated operation in the current industrial market. At the same time, it also summarizes the four demands of industrial applications. First, it needs longer battery life. Technically, it needs ultra-low power chips and energy optimized communication protocol stacks. In addition, it can extend battery life through energy collection technology. Second, reliable connection is required, which can be realized by adopting a protocol stack with higher forward error correction rate, or by using frequency hopping sub GHz and 2.4G dual band. Thirdly, integrating artificial intelligence and machine learning, local data processing is carried out through the built-in AIML coprocessor, so as to reduce power consumption and avoid network channel congestion. Fourth, high security needs to be embedded to avoid the execution of abnormal code and to deal with illegal cracking, so as to meet the requirements of the latest security regulations and OTA of security functions.

At this seminar, silicon labs brought the latest solution fg23 for industrial automation applications. Fg23 is a new product specially designed for the industrial Internet of things customer group that develops equipment using sub GHz proprietary protocol. The radio supports all common sub GHz bands in the world, and its sensitivity is about 3dB higher than other similar radios. This means that this SOC can help developers communicate over longer distances, up to more than a mile. At the same time, in terms of security, fg23 also supports the unique security vault patented technology of silicon labs, which has extremely high security and can pass the authentication of arm PSA leval 3.

Fg23 has a high-performance wireless transmission function, with a maximum transmission power of 20dbm and a sensitivity as low as – 160dBm. It supports antenna diversity reception and has extremely low power consumption. At 14 DBM 825mhz, the TX current is 25mA, the receiving current is only 4.2ma, and the standby current is as low as 1.2 μ A. It also supports the ultra-low power consumption of the preamble aware wake-up function.

Thanks to its excellent performance, fg23 can be widely used in intelligent meter reading, industrial automation, intelligent lighting, building automation, IOT gateway and many other applications.

At the same time, silicon labs also introduced the industry’s only xg24 integrated with ai/ml accelerator, which mainly covers the fields of smart home, building automation, lighting, portable medical treatment, artificial intelligence and machine learning. Through the optimization of the accelerator, xg24 can share the workload of machine inference operation of the CPU. Its operation speed is two to four times that of Cortex-M, and its energy consumption is only 1/6 of that of cortex-m. With the help of this accelerator, xg24 can process picture data locally to realize fingerprint identification, and can also process audio data to realize functions such as voice control and motor fault detection.

The processed data can also be the time-based data from any sensor, and the machine inference is realized through local algorithm operation. This automatically performs the corresponding behavior. This accelerator makes artificial intelligence and machine learning more efficient, so as to achieve low energy consumption and low latency, minimize the dependence on network communication, and improve security.

In order to bring users a more comfortable development environment, silicon labs can also provide customized services for customers, which can help customers burn firmware and security configuration into the chip before leaving the factory. This kind of pre burning service can fully protect the security of customer software and information, and avoid the leakage of secrets in the factory production stage.

Electronic enthusiast network: domestic industrial control brands stand firm,TSNand5Grise

At this technical seminar, zhoukaiyang, editor of electronic enthusiast network, shared the analysis of industrial control and industrial communication market, and analyzed the opportunities and challenges in the industry. Industrial control system is a general term for different types of control systems and related equipment and instruments, mainly including control equipment, systems and networks. From the upstream, it is mainly divided into industrial control / communication chips and modules, as well as industrial sensors. The main bodies of the midstream are PLC, DCS and SCADA. The controllers and systems of these three control layers, and the downstream of the industrial control and communication market are concentrated in applications such as industrial robots, industrial routes, industrial gateways and industrial Internet platforms.

Although affected by the epidemic, the deployment of industrial automation has slowed down, it still maintains a positive growth. In the first half of last year, the impact of core shortage was relatively serious. In addition, limited stock and repeated overseas epidemics promoted the hot situation since the end of 2020, broke through the traditional off-season demand, and achieved a year-on-year increase of more than 40% in the first quarter. In the second quarter, the panic of core shortage began to be digested, and the demand gradually became normalized until the third quarter, with an average year-on-year increase of about 11.9% in the two quarters. In the fourth quarter, energy consumption was under dual control The rising prices of raw materials and the repeated impact of certain epidemics have further reduced demand, and the trend of rising prices has been reflected in the first half of this year. Since the beginning of this year, domestic and foreign industrial automation manufacturers have issued a series of price increase announcements, which is based on the fact that prices have been raised several times last year.

The bonus brought by mask machine to PLC and other industrial control products is slowly slowing down. However, due to the repeated epidemic and the global awareness of medical supplies, the automatic production of medical devices will continue to be a considerable growth point. In addition, all countries are still adhering to certain epidemic prevention measures, especially in China, some new enterprises involved in the production of such products are still a cake that can not be underestimated, and also the performance growth point of many domestic automation manufacturers.

In addition to medical supplies, the demand growth of advanced manufacturing and OEMs such as semiconductors, lithium batteries and industrial robots is also strong. In terms of products, the growth is mainly small PLC. Large PLCs are still concentrated in the project-based markets such as power, petroleum, petrochemical and chemical industries. The impact of the epidemic has slowed down to a certain extent, but the body volume is large enough, so the total market value is still huge.

In the domestic PLC market, foreign brands from Europe, America and Japan still occupy a dominant position, especially Siemens’ market share is nearly half. At present, small and medium-sized PLCs are still the main products in China. Many of them have gained a firm foothold and begun to penetrate the market, such as the mask machine just mentioned. At the same time, it can be seen from the release of new products and the annual reports of enterprises that some manufacturers are also breaking through the technical barriers, launching and laying out medium and large-scale PLCs, such as Baoxin, Alto, etc., but the market share is still dominated by Rockwell and other manufacturers.

In the survey conducted by the electronic enthusiast network, nearly half of the users believe that industrial control products at the control layer such as PLC and DCs can be perfectly replaced by domestic products. However, this is largely due to the confidence brought by DCs, especially the high share of central control technology and Hollysys in the DCS market. However, in downstream industries, domestic DCS is still dominated by chemical and petrochemical industries, and DCS in electric energy is dominated by foreign brands.

The domestic brands of SCADA system account for more than half of the total, but there is still room for replacement. Especially when foreign brands start to acquire one after another to improve their competitiveness, grasping the hot applications of water treatment such as green energy, smart grid, South-to-North Water Transfer and smart water plant will be the opportunity for breakthrough.

In our user survey, 54.7% of users use industrial Ethernet, 31.3% use fieldbus, and less than 20% choose industrial wireless network. However, the growth rate of industrial wireless network is still considerable. It can be seen from the statistical data of HMS that although the proportion of industrial wireless network remains unchanged, the annual growth rate of 8% is close to that of industrial Ethernet.

In order to use, manage, maintain and control industrial equipment efficiently, it is necessary to take the network communication platform and technology that provide deterministic service quality as the support; The networking and intelligent upgrading of industrial manufacturing also put forward requirements for the network to provide deterministic quality of service. TSN time sensitive network has become a trend. The research on the integration of industrial network and TSN includes industry standard organizations related to Ethernet (CC link, EtherCAT, PROFINET) and domestic industrial Internet industry alliance.

The arrival of 5g has also created new opportunities for industrial wireless networks, but 5g networks have only experienced a wave of explosive growth and are still in the process of improvement. Despite the promotion of relevant policies, many factories are still waiting to see what impact 5g can bring to the next generation industrial communication network. It can also be seen from our survey report that among the emerging industrial control and communication solutions, 5g smart factory is the most attractive, accounting for 28%.

However, there are still some challenges in 5g industrial Internet. For example, in terms of reliability, 5g reliability cannot be stably maintained above the target of 99.9999%; In terms of improving communication capacity and efficiency, pilot projects are still carried out in some regions, and there is no large-scale expansion. The last and most important link is terminal support. At present, a small number of 5g supporting industrial gateway and router equipment have begun to be shipped, but there are still not many terminal equipment. In the future, the number of participating manufacturers will increase and the degree of product and technology perfection will be higher, which is bound to bring about a decline in costs and promote the popularization of terminals. In addition, the network security capability after 5g technology integration needs to be improved, and the supply chain security can not be fully controlled, especially 5g chips.
