Domestic industrial personal computer mainboard integrated with multi-serial-port chip and industrial personal computer

Abstract

The invention discloses a domestic chemical control computer mainboard integrated with a multi-serial-port chip and an industrial control computer. The domestic chemical control computer mainboard integrated with the multi-serial-port chip comprises a mainboard body, a CPU, a bridge chip, the multi-serial-port chip, an interface chip and a serial communication interface, wherein the CPU, the bridge chip, the multi-serial-port chip, the interface chip and the serial communication interface are integrated on the mainboard body; the bridge chip is connected with the CPU; the multi-serial port chip is connected with the bridge chip and the interface chip; and the interface chip is connected with the serial communication interface. By implementing the embodiment of the invention, the problems of loose connection, poor contact and the like due to the fact that the multi-serial-port chip and the mainboard are connected by adopting a PCIe card slot in the prior art can be effectively solved.

Description

technical field [0001] The invention relates to the technical field of computers, in particular to a main board of a domestic chemical control computer and an industrial control computer integrated with multiple serial port chips. Background technique [0002] The traditional universal driveway industrial computer mainly has two forms. The first one is that the central processing unit and multi-serial port chips are independently designed in the form of PCI / PCIE boards, and then connected through a passive backplane with multiple PCI / PCIE slots. The second type is similar to a conventional computer, and the multi-serial port expansion card is linked through the PCIE slot of the central processing unit motherboard. Both forms link the main control chip of the driveway industrial computer with the extended serial port chip through the PCIE slot, but the above-mentioned methods are prone to loose links between boards and cards, poor contact, and gold finger aging due to environ...
