Built-in type 4 axis sport controller

Abstract

The invention discloses an embedded four-axis motion controller which comprises a main controller and a motion control module. An output of the main controller is connected with the motion control module through an output interface, and the motion control module is respectively connected with an X-axis motion component, a Y-axis motion component, a Z-axis motion component, and a U-axis motion component. The controller of the invention adopts an S3C44BOX chip based on an ARM7TDMI core which is promoted by the Samsung company as the main controller, adopts a motion control chip MCX314As which is specially used by the NOVA company in Japan as an interpolate controller, adopts a PC104 bus interface with strong insertion ability, combines the embedded CPU with a special DSP motion control chip, embeds the motion control function in the framework of the ARM main control plate with a PC 104 function module method, cuts off the equipment that is not in need, has a plurality of functions and saves the cost. The invention is an independent motion controller which can be separated from a host computer and is characterized by strong computing ability and low cost, thereby extremely reducing the size of the system, lowering the power consumption, and improving the reliability and the openness of the system.

Description

Technical field: [0001] The present invention is an embedded four-axis motion controller, specifically an embedded four-axis motion controller based on the PC104 bus, which uses the ARM7 chip S3C44B0X as the master controller and the dedicated DSP motion control chip MCX314As as the slave processor. device. It belongs to the transformation technology of motion controller. Background technique: [0002] During the development of motion controllers, motion control platforms with single-chip microcomputers, application-specific chips (ASICs), DSPs, and FPGAs as core processors have emerged. Among them, the main motion controller currently on the market is based on the "PC + motion control card" motion controller, which organically combines the information processing capability and open features of the PC with the motion trajectory control capability of the motion control card. But this method has great limitations in structure and performance: [0003] (1) The motion control...

AI Technical Summary

Problems solved by technology

But this method has great limitations in structure and performance:

[0003] (1) The motion control card cannot be separated from the computer bus, and needs to be inserted into the PCI or ISA slot of the computer motherboard. Therefore, a PC must be configured as the upper computer for each specific application, which undoubtedly affects the size, cost and operating environment of the equipment. There are certain limitations, it is difficult to operate independently and miniaturize

[0004] (2) Since the general-purpose industrial PC platform is used, the hardware cannot be tailored. For many occasions, many functions on the PC are not used, and the user still has to pay the cost

Because it is impossible to tailor the system software and hardware according to the characteristics of the motion control system, the use of general-purpose industrial PCs cannot well build an embedded motion control platform

[0005] (3) The stability of the system is not very good

Industrial PC computers use the general Windows operating system when running. On the one hand, the Windows system is not a real-time operating system and cannot respond in time to the special conditions of on-site processing, which will lead to system instability; on the other hand, the Windows system is easy to be infected. Viruses cause system crashes and increase the difficulty of system maintenance
