Abstract

The invention relates to the CPCI bus data transmission technology, and specifically provides a 3U network expansion board card based on CPCI bus interfaces, which solves problems of incompact general layout of a gateway and poor adaptability of field installation condition in the prior art. The 3U network expansion board card based on CPCI bus interfaces comprises an FPGA chip, an EPLD chip, a first single-chip microcomputer, a second single-chip microcomputer, a CAN network interface, an I2C management chip, a clock generator, a first network interface, a second network interface, a third network interface, a fourth network interface, a multipath selection switch, a reset chip, a Flash configuration chip, a PCI9056 bus bridge interface chip, an EEPROM configuration chip, and a JTAG bus management special chip. The 3U network expansion board card based on CPCI bus interfaces can be applied to fields such as metallurgy, automobile manufacture, tobacco machinery, environment protection, petrochemical industry, electric power energy and weaving machinery.

Description

technical field [0001] The invention relates to a CPCI bus data transmission technology, in particular to a 3U network expansion board based on a CPCI bus interface. Background technique [0002] As a reinforced enhanced industrial computer, 3U standard embedded industrial computer is widely used in metallurgy, automobile manufacturing, tobacco machinery, environmental protection, petrochemical, electric energy, textile machinery and other fields. In practical application, data communication is carried out between various functional boards inside the 3U standard embedded industrial computer through the CPCI bus. The 3U standard embedded industrial computer mainly exchanges data with external devices through field buses (such as PROFIBUS, DeviceNet, Foundation, Fieldbus, Interbus_S, etc.). In the process of data exchange, in order to realize the conversion with various fieldbus protocols, the transition between the 3U standard embedded industrial computer and the fieldbus mu...
