Source electronic hard disk in industrial computer applications

The industrial control computer is the industrial control computer. It is a general term for the tools that use the bus structure to detect and control the production process and its electromechanical equipment and process equipment. Has important computer attributes and characteristics, such as a computer CPU, hard disk, memory, peripherals and interfaces, and a real-time operating system, control networks and protocols, computing power, and friendly human-machine interface. In 1983, IPCs were included in the national computer series spectrum and development plan. The main categories of current IPCs in China are: IPC (PC Bus Industrial PC), PLC (Programmable Control System), DCS (Distributed Control System) ), FCS (field bus system) and CNC (CNC system) five kinds.

Since IPC (Industrial PC) can make full use of the advancement of computer technology, and is easy to update, the software it runs is exactly the same as an ordinary PC, which is convenient for software development and debugging. Therefore, it is currently the fastest growing model.

IPC: An industrial PC based on the PC bus. According to the statistics of IDC in 2000, PCs currently account for more than 95% of general-purpose computers. Because of their low price, high quality, large output, and rich hardware and software resources, they have been familiarized and recognized by a large number of technical personnel. This is exactly the industry. Computer hot basis. Its main components are industrial chassis, passive backplanes, and various boards that can be plugged into it, such as CPU cards and I/O cards. And take the design of all-steel chassis, machine card bead filter, double positive pressure fans and EMC (electro magnetic compatibility) technology to solve the electromagnetic interference, vibration, dust, high / low temperature and other issues in the industrial field.

1) Reliability: Industrial PCs have dust, smoke, high/low temperature, humidity, vibration, corrosion, and rapid diagnosis and maintainability. Their MTTR (Mean Time to Repair) is generally 5 minutes, MTTF is more than 100,000 hours, and common The MTTF of a PC is only 10,000 to 15,000 hours.

2) Real-time, industrial PCs conduct real-time online detection and control of industrial production processes, giving quick response to changes in working conditions, timely acquisition and output adjustment, (watchdog function is not available in ordinary PCs). Reset to ensure the normal operation of the system.

3) Expandability: Industrial PC adopts the backplane + CPU card structure, so it has a strong input and output capabilities, can expand up to 20 boards, and with a variety of peripherals and boards in the industrial field, such as with the controller, video Monitoring systems, vehicle detectors, etc. are connected to accomplish various tasks.

4) Compatibility, ISA and PCI and PICMG resources can be used at the same time, and supports a variety of operating systems, multi-language compilation, multi-tasking operating system.

We know that the difference between IPCs and ordinary PCs lies in the bus architecture of their motherboards, the design of the chassis, and the scalability of industrial backplanes, which are strictly implemented according to industry standards. However, as a control system that can operate in harsh environments over a long period of time, all data processing needs to be read and written on the hard disk by CPU operation. The storage problem has always been a difficult point for industrial control manufacturers, because ordinary mechanical hard disks are due to their inherent mechanical structure. The components, running in a high-temperature, wet-and-vibrating working environment, are prone to stalling the entire industrial control system due to the failure of the hard disk and affecting the system's working efficiency. Runcore SSD adopts NAND flash memory media and is completely semiconductor-based. There is no mechanical component, and military-grade standards can be achieved in shock-proof and anti-fall, and it can completely adapt to the harsh working environment in industrial applications. -Extra wide operating temperature range from -45°C to 85°C, random access speed of 30MB/s or more, and MTBF time of more than 2 million hours, in addition to meeting the normal operation of IPC in the industrial environment, it also has the performance of the whole machine. The big upgrade will make the entire industrial control system more stable and reliable.

In addition to making the IPC more stable and reliable in performance, the Runcore SSD has the same dimensions as the traditional mechanical hard disk standard. There are several common specifications such as 1.8", 2.5" and 3.5". The interface uses the IDE or SATA interface and is completely compatible with the PC hardware. , And support for Windows9X/Me/NT/XP/CE/Vista, MAC, Linux and Unix and other operating systems.According to the needs of user data processing capacity, from 1GB to 32GB to choose from, you can also use Raid card technology Solid-state disk arrays expand the storage capacity of the entire system.
