For Industry 4.0, different companies have different interpretations, and interconnection is its biggest feature. All devices in an industrial application are connected by wired or wireless means such as fieldbus, industrial Ethernet, RFID, or even Wi-Fi, and then connected to the cloud through a gateway. Freescale provides industrial control and networking solutions for many wired and wireless industrial communication protocols and human-machine interfaces. Its security systems can withstand hacking, cloning, tampering and soft errors in the harsh environments of manufacturing or processing plants.
Optimize industrial applications
Among Freescale's many products for industrial communications, the latest QorIQ dual-core T1024 and T1023 communications processors are quite remarkable. The T1024 and T1023 offer optimized features for the industrial market, including display interface units for HMI, QUICC Engine for industrial protocol offloading, and error checking and error correction (ECC) support for high reliability "always on" applications. The QUICC engine module provides comprehensive support for traditional WAN protocols such as TDM, HDLC, UART, ISDN, and industrial protocols.
The T1024 and T1023 are equipped with a 64-bit core and are built on Power Architecture technology to provide the High Performance Data Path Acceleration Architecture (DPAA) and network peripheral bus interface required for networking, telecom and industrial networking applications. Target applications include: wired and wireless branch routers, WLAN 11ac enterprise access points, service provider WLAN access points, unified threat management gateways, multifunction printers, router and switch controllers, line card controllers, industrial automation and Computing, single board computers, aerospace and defense-grade rugged network equipment.
The new QorIQ T1023 and T1024 processors combine the scalability of seamless applications with an excellent offload performance upgrade path for the popular QorIQ P1 series and PowerQUICC processors. The T1023 device targets 802.11ac smart edge WLAN access points and branch routers, while the T1024 SoC cost-effectively upgrades printing and imaging, legacy control applications and line cards.
The art of balance - performance and energy efficiency
Compared with popular ARM cores, Power Architecture has a long history of industrial connection and has proven its reliability and security in industrial and communications. The e5500 architecture is twice as fast as the Freescale e500 core, with a design frequency of up to 2.5 GHz and can run in either 64-bit or 32-bit mode. The 64-bit e5500 core implements many improvements, including support for multi-core SoC implementations and heterogeneous multi-core processors, and a unique combination of integration and performance that achieves very high performance levels in a very low power range for embedding Energy efficiency sets a benchmark.
T1023/24 processor with 2 or 4 e5500 single-threaded cores with Power Architecture technology, up to 1.4GHz with 64-bit ISA support; low latency, per core, core timing, 256KB dedicated cache; mixed 32-bit mode, support Traditional software and transition to 64-bit architecture; 32/64-bit DDR3L/4 SDRAM memory controller with ECC support up to 1600MT/s.
One of the characteristics of the T1023/24 is the perfect combination of performance and power consumption. It can be said to be “smart energy savingâ€, which is reflected in several aspects: firstly, the performance per watt reaches 1800 Coremark; the total power consumption is less than 4W (the main frequency is 1.4). GHz); e5500 core supports different levels of low power modes (sleep, wait and burnout); provides deep sleep support via ECMA 363-based automatic response, no packet loss; meets energy consumption standards such as European Code of Conduct, Energy Magnitude.
In addition, the F104S8A four-port Gigabit Ethernet copper PHY is recommended as a companion device to the T1023/24 communications processor. The F104S8Aq device optimizes the power consumption of all link operating rates.
Worry about information security
Recently, a robotic accident that occurred in Germany has caused widespread concern in the industry, sparking a discussion about the safety of robots. In fact, there is absolutely no need to panic, because from the smart home to Industry 4.0, these IoT applications have placed great emphasis on security at the beginning of design. Security includes three aspects: physical security, functional security, and information security. Take the robot arm of the factory as an example. Physical safety refers to the safety of its location, such as weather and earthquake applications. Functional safety means that it can work normally without causing failure or damage to other things. Information security means that the data it receives and sends is secure, free from hackers, and only authorized users can interact with it, and even authorized users of different levels have different operational rights.
So what can Freescale's communications processor do in terms of security? Taking information security as an example, all ports of T1023/24 are equipped with MACsec, which is a main protocol for protecting LAN security. This protocol prevents the communication from being carried out by identifying non-trusted sites on the LAN, thus ensuring the normal operation of the network. It also protects information integrity and confidentiality and reduces attacks on Layer 2 protocols. The T1023/24 also supports hardware virtualization and partition execution with additional privilege levels for hypervisor support. There are three levels of instructions: users, superusers, and hypervisors, and grading is one of the most effective measures for information security, preventing people without permission from causing damage to the system. In addition, the QorIQ Trusted Architecture provides features such as secure boot, secure debugging, tamper detection, and volatile key storage.
What is a miniature slip ring? Miniature slip rings are rotary electrical connectors that allow power and data to be transferred between a stationary and rotating structure. They are often used in medical, military, and aerospace applications where size and weight are critical factors.
A miniature slip ring typically consists of two parts: a stationary housing and a rotating contact assembly. The contact assembly contains the brushes that make electrical contact with the rotating structure, as well as the rings that conduct current or data.
The housing can be made from any number of materials, including metals, plastics, and composites. It is typically designed to be as small and lightweight as possible while still providing adequate strength and durability.
The contact assembly is made from precious metals such as gold or silver in order to provide good electrical conductivity.
Technology improves with the continuous development of precision machinery. The more sophisticated the equipment, the smaller the volume will be. And the space that can be accommodated for installing the slip ring is also very small. The key parts of some equipment are quite a district. Especially in the high-end military, aerospace and aviation fields. 360-degree rotation is required to transmit current and signals. And the installation space is greatly reduced. It is to make the equipment work more smoothly. Therefore, it is necessary to design the slip ring to be small and exquisite. Otherwise, it won't meet the needs of the installation.
At the same time, we have moved with the continuous development of science and technology. Various high-end precision instruments have been developed. It requires the slip ring to transmit the current amount of general power. Also often undertake the transmission of weak electrical signals and various weak signals. The transmission medium is wider, and the number of loops of the slip ring is increasing.
