Problems solved by technology

Due to the versatility of Labview, it limits its depth in certain professional fields, such as high-speed and high-precision electromechanical control related tests in lithography machines
[0003] In the development of embedded systems (including DSP, single-chip microcomputer and PPC, etc.), since there is no visual debugging interface, the integration and maintenance work is more difficult
[0004] Due to individual differences in development environments and different systems, it is difficult to develop a common integrated test platform for embedded systems
[0005] NI's industrial control products adopt common peripheral equipment interfaces, such as 16 or 18-bit A / D interface boards, 16-bit D / A interface boards, and some general digital I / O boards, etc. In addition, the motion control cards used It can only meet the control of ordinary motors, such as the control method of motor + encoder in most electromechanical products, its control algorithm is fixed, and it is difficult to expand

Embodiment Construction

[0022] The specific embodiments of the present invention will be further described below in conjunction with the accompanying drawings.

[0023] Figure 1 shows the outline of the control system integrated test device, which is mainly composed of six parts: controller 1 (currently using PPC), motion control card 3 (MC), multi-function digital analog interface board 5 (MIO ), terminal 6, first power module 7 and second power module 8, and main backplane 9. Among them, the controller 1 has two main interfaces, which are VME interface 11 and network port 14 respectively. The motion control card 3 also has two main interfaces, namely a high-speed serial communication port 2 (HSSL) and an RS485 interface 4 . Data communication can be performed between the controller 1 and the motion control card 3 through the VME interface 11 . The multifunctional digital analog interface board 5 has a main interface 2 for high-speed data communication with the motion control card 3 . The multifu...

Abstract

The invention discloses an integrated testing device for a control system, and the device adopts complex embedded system integration, thereby being convenient to expand the functions of systems, and using a visual interface to support the system integration work. In addition, the invention can realize the multi-axis motion control, the high-performance motion control, the on-site maintenance, and the hardware in-loop simulation.

Description

technical field [0001] The invention relates to a control system integration test device, in particular to a control system integration test device using a complex embedded system. Background technique [0002] NI (National Instruments Corporation)'s industrial control products use a real-time operating system (RT) for servo control, and users can write corresponding control programs through Labview. The real-time operating system needs to spend more time to maintain the operation of the system, thereby reducing the control performance of the servo system (the sampling frequency is difficult to increase), although a high-performance processor is used as the controller of the RT, but the RT is difficult for some external devices There are defects in the processing of the system, which affects the improvement of the sampling frequency of the system. As a general test platform software, Labview provides various convenient test modules for users. Due to the versatility of Labv...
