What is an industrial computer backplane? The backplane is also called the Back Plane and is installed in the middle blank of the empty chassis. Different types of backplanes are usually selected according to needs, and different backplane designs will make an industrial chassis contain different numbers of systems, and each system has a motherboard contained in it.
If a large number of systems are installed on a backplane, the power consumption of the system may be insufficient due to increased power consumption. In the case of 241: uninterrupted operation every day, it is very likely that the power supply of the system cannot be tolerated and the power supply is damaged. A 350W power supply can be used.
The passive backplane is generally designed as a multi-slot backplane in the form of a bus structure (such as STD, ISA, PCI bus, etc.), and all electronic components are modularized and easy to maintain. The slot of the passive backplane consists of multiple slots of the ISA and PCI buses. The number and position of the ISA or PCI slots can be selected according to the needs. Generally, it is a four-layer structure, and the middle two layers are the ground layer and the power layer respectively. This structure can reduce the mutual interference of the logic signals on the board and reduce the impedance of the power supply. The backplane can be plugged with various boards, including CPU cards, display cards, control cards, and I/O cards.
The passive backplane structure is adopted instead of the large board structure of commercial machines, which improves the scalability of the system and can be extended to up to 20 boards; reduces the probability of crashing, simplifies the error checking process, and facilitates board insertion and removal , fast repair time is short; makes upgrades easier and makes the entire system more efficient.
