An Integrated Monitoring System of Industrial Control Buses Based on FPGA
Aiming at the problems existing in the field test of industrial control buses in engineering monitoring,in order to simplify the carrying capacity of equipment and improve the adaptability of monitoring to complex application scenarios,a data integrated monitoring system based on FPGA,connected to the upper computer through PCIe and supporting IIC and SPI buses is proposed.Firstly,the overall design of the integrated monitoring system is given,and then the detailed design schemes of hardware and logic are given according to the principles of hardware reconfigurablity and software field definition.Eight paths of IIC and SPI are designed to meet the problem of excessive industrial monitoring equipment.Hardware interfaces are reduced and software protocol options are increased.According to the requirements,the top-down design module is analyzed and divided to complete the code design.According to the fault-tolerant ability,the monitoring and fault injection functions are designed,the board-level debugging is carried out,and the upper computer test is finally completed.The results show that the designed communication board is qualified and passed the overall verification.
