Asynchronous multi-core programmable automation controller (PAC)

Abstract

The invention discloses an asynchronous multi-core PAC. The PAC comprises an analog main board, an input / output (I / O) main board, a motion control main board, a diagnose module, a synchronous debugger, a custom enhancement mode software process improvement (SPI) bus and a baseboard which is provided with a power supply communication device and a synchronous debugging bus, wherein the three main boards are installed on the baseboard provided with the power supply communication device and the synchronous debugging bus through pins, connected through the custom enhancement mode SPI bus respectively, and respectively connected with the diagnose module connected with a personal computer (PC); five daughter boards are installed on corresponding main boards; and the synchronous debugger is connected with the PC and the three main boards respectively. According to the PAC, multi-core asynchronous operation can be achieved, the problems that the clock frequency of a single-core processor is difficult to improve and the power consumption of the processor is large are effectively solved, and a good start is provided for solving the problems of safety and stability of control systems, reduction of the software development difficulty and the like.

Description

technical field [0001] The invention belongs to the field of industrial automation control, in particular to a programmable automation controller (PAC), in particular to an asynchronous multi-core programmable automation controller. Background technique [0002] With the increasing demand for industrial control equipment, it is increasingly difficult for the current control system to meet the more functional requirements of modern industrial applications. In order to meet the requirements of modern industrial control system applications, people have proposed programmable automation Controller (PAC), Programmable Automation Controller (PAC) is gradually replacing Programmable Logic Controller (PLC), becoming an ideal choice for industrial control systems. However, at present, most PACs still use the single microprocessor (MCU) mode used by PLC, which makes the load on the control system very high, which easily leads to real-time problems in multi-tasking systems. Therefore, i...
