Abstract

The invention relates to a PLC cooperative control device based on an SOPC technology. The device comprises two parts, a hardware system and a software system. The hardware system comprises an upper computer and a lower computer. The upper computer is formed by a Nios II soft core processor module, a memory module and a peripheral module, wherein the Nios II soft core processor module is composed of a CPU module, a TIMER0 module, a TIMER1 module, an UART module and a JTAG module. The software system comprises an embedded uC / OS-II real-time operating system, upper computer software, lower computer software and a virtual soft core PLC. The PLC cooperative control device is high in modifiability and transportability; the uC / OS-II real-time operating system is added, the operation real-time performance of the system is ensured, customized IP cores can be compiled according to specific requirements, and the required specific functions can be added freely; in addition, the number of I / O ports can be conveniently increased or reduced, so that the system is high in expansion and maintenance performance.

Description

technical field [0001] The invention relates to an industrial control programmable logic embedded soft-core PLC device, in particular to a device for realizing industrial automation control based on collaborative PLC of SOPC technology. Background technique [0002] Because the traditional hardware PLC technology is closed to the outside world, the PLC hardware platforms of various manufacturers are different, the supported PLC languages ​​are also different, and the protocols and buses for communication between them are also completely different. Therefore, with the development of computer technology, people have gradually realized that the poor versatility, compatibility and expandability of hardware PLC are restricting the rapid development of PLC. At the same time, with a new round of technological transformation in the cigarette industry, a large number of new tobacco shredding equipment has been imported from foreign tobacco machine equipment companies such as HAUNI in...
