In one embodiment, CPCI backplane 300 is mounted inside chassis 100 by a cage.

The cage is a device for providing expansion slots and protecting hardware parts inside a computer, and comprises a metal shell and a plurality of expansion slots, wherein different types of expansion cards can be inserted into the expansion slots to meet application requirements. The board card and other modules are directly inserted into the slot of the cage to carry out bus communication on the floor of the slot. The arrangement of the machine cage makes the structure between the boards compact, and the boards can be independently replaced when faults occur, but the machine cage is not suitable for flexible expansion due to the limitation of the number of the machine cage expansion slots.

The CPCI backboard 300 of the present embodiment may be installed in an industrial personal computer through a six-slot cage, and a new rear panel is customized for the industrial personal computer after installation, so that the industrial personal computer is more compact and beautiful.

In conjunction with the connection schematic diagram shown in fig. 2, in one embodiment, the CPCI backplane 300 is connected to the MINI-PCIe interface of the motherboard 200 through a pci ex1 bus.

The MINI-PCIe interface is a small PCIe interface provided on the motherboard 200, and may be used to connect to an expansion card. The pci ex1 bus is a bus capable of improving a higher transmission speed, and can be used for faster data transmission, and the pci ex1 bus can be used for connecting various expansion cards to realize data transmission between the motherboard 200 and the expansion board card.

As shown in fig. 2, CPCI back plate 300 has dimensions of 120.92mm by 128.7mm by 3.2mm, and the board card has 12 layers. In this embodiment, the pci back board 300 is connected with the motherboard 200 through the pci ex1 bus, so as to realize expansion of the motherboard 200 of the industrial personal computer, and CPCI resources can be expanded on the industrial personal computer only by connecting the bus, so that the connection is simple and easy to realize.

In another embodiment, the CPCI backplane 300 is connected to an on-board Mini-PCIe interface through an extended two-way PCIe interface.

The on-board Mini-PCIe interface means that the PCIe interface is integrated on the motherboard 200, and compared with a standard PCIe slot, the on-board Mini-PCIe interface is smaller, so that the on-board Mini-PCIe interface can be easily integrated on the motherboard 200 in a limited space. Due to the small size and standardized design of the Mini-PCIe interface, users can conveniently replace or add different types of Mini-PCIe expansion cards, such as wireless network cards, memory controllers, communication modules and the like, according to requirements.
