From the traditional ISA bus, through the PCI bus, to the PCIE bus, the development of IPC bus technology has passed three eras. Based on ISA skills, it is called the first generation of IPC bus skills. PCI-based PCI, CPCI, and PXI is called the second generation transfer skill. The third-generation transmission technology is PCIE, CPCIE, and PXIE. The third-generation transmission technology is a low-voltage differential transmission, and it is also a point-to-point serial transmission. The speed is faster and the anti-interference ability is stronger. No.
The second-generation transmission technology has reached industrialization and there are many mature products.
Embedded skills use With the development of hardware skills, various CPUs and programmable logic devices will be widely used, and the level of intelligent single boards will be greatly increased, and the category of IPCs will also be more and more abundant. In addition, miniaturized, real-time operating system makes industrial control The use of the machine is simpler and will be used in many ways.
Software skills use IPC is inseparable from software. The current trend is the hardwareization of hardware. The solution is based on hardware channel skills or the direct use of pure software. Such as IP cores in logic devices, soft logic, time synchronization skills (IEEE1588). In addition, software engineering is the process of building the entire system through software skills. Such as virtual instruments, network instruments, remote measurement and control equipment.
Communication skills use Whether it is an intelligent factory or an intelligent substation, it is still the Internet of Things and the Internet. Whoever supports the communication skills will do well. Whoever uses the IPC will use it well. IPC The same is true for chips, which are those chips that support good communication support. This chip may be widely used. Therefore, Ethernet skills and field bus skills will be applied in large-scale and large-scale applications in the future.
Measurement and control system use The IPC is actually a fundamental thing, and it is ultimately required to be used in the measurement and control system, that is, in the DCS measurement and control system. In terms of networking, these features, hierarchical structures, and the use of communication skills are also now available.
This makes the current measurement and control system more network-oriented. As the basic unit of this monitoring and control system, it can be divided into two categories. One is based on the traditional PLC measurement and control unit, this many large manufacturers of DCS are based on the PLC . There is another category that is based on the PC's DCS measurement and control system, using industrial computers to form DCS. Taking the PXI bus IPC as an example: According to the measurement and control system of the PXI industrial computer, it is based on the PXI IPC as a measurement and control unit to build a large, Medium-sized networked monitoring and control system. Due to the selection of a high-speed PXI bus, the overall scanning speed of the control unit is very fast, and the cooperative embedded real-time operating system can complete high-speed data acquisition and can fully meet the need for quick response.
Should be the logical manipulation and process control.
Internet of Things Use As the basic test unit, IPC can play a very important role in linking the entire Internet of Things. The development of industrial computers will also advance the development of the Internet of Things.
Now, the use of IPCs has become very widespread. Regardless of whether it is in the field of industrial sites or industrial automation, many medical and transportation professionals are already using IPCs. In the future, IPC occupation is still a city regardless of skill perspectives. The field of view, or the use of levels, will be widely implemented.
