[0013] 2. The second reason that restricts the development of existing digital control systems into control machines is reconfigurability
[0015] 3. The third reason that restricts the development of existing digital control systems into control machines is standardization
In this case, the existing open digital control system has no reconfigurability at all
[0028] Third, from a standardization point of view, the digital control system must only produce the control information required by the working machine
A large amount of redundant information such as interpolation cycle and contour step size caused by real-time operating system has become a serious obstacle to the standardization of digital control systems
[0029] The above analysis shows that the strong correlation between the existing open digital control system and the real-time operating system under the leadership of the IEEE definition leads to the closedness of control information, control method, control process and architecture, poor reconfigurability, and poor standardization and reliability. serious obstacles to
These defects prevent the embedded subsystems in the existing open digital control system from evolving into standardized "components", thus preventing the existing open digital control system from evolving into the control machine expected by the third industrial revolution.

specific Embodiment 1

[0121] In this embodiment, an embodiment of a standardized DRC control machine is provided, such as figure 1 As shown, it consists of three types of functional components: control information generation component 01, control information distribution and transmission component 03, and control information execution component 04:

[0122] The control information includes a multi-axis associated data stream, a multi-parameter associated data stream, and a switch control stream; the multi-axis associated data stream controls the contour motion of the shaft in real time, the switch control stream controls the switch system in real time, and the multi-parameter associated The data stream controls the process parameters in real time; the control information is stored in the data control stream file, namely the DCFS file;

[0123] The control information generation component 01 transmits the DCFS file to the control information distribution sending component 03;

[0124] The control i...

specific Embodiment 2

[0153] In this embodiment, a reconfiguration method and a stored information control method of the DRC control machine are proposed.

[0154] The reconfigurable manufacturing system has two basic requirements for the reconfigurable control system:

[0155] First, reconfigurable manufacturing systems require an all-round open digital control system. The control information generation unit 01 and the control information distribution sending unit 03 have the openness required by the reconfigurable manufacturing system.

[0156] Second, the modern digital control system constitutes a complex embedded system through the I / O system. The reconfigurable control system needs to change the I / O function in real time to adapt to different I / O systems, that is to say, the I / O system must be reconfigurable. A reconfigurable control system requires an open, reconfigurable I / O system.

[0157] Based on the above requirements, such as Figure 4 As shown, the embodiment of the standardized ...

specific Embodiment 3

[0236] Figure 5 It is a schematic diagram of the architecture of the DRC control machine in this preferred embodiment.

[0237] The control information generation part 01 is connected with the control information distribution sending part 03 through the system bus (for example, Compact PCI or PCI—PCI bridge), that is to say, the control information distribution sending part 03 is integrated in the PC, in contrast to the soft open mode . What adopted is industrial PC. Obviously, this preferred implementation can complete all the control tasks that the soft open mode can accomplish, but overcomes the defects of the soft open mode, and has beneficial effects that the soft open mode does not have.

[0238] In the above specific implementation, the reconfigurable machine tool is used as the working machine, and the architecture of the DRC control machine and the storage information control method and reconfiguration method of the DRC control machine are described in detail. The...

Abstract

The invention provides a full-open, software restructured and high reliability standardized controlling machine which is completely computerized and also provides a stored information control method and software restructured method. The standardized controlling machine solves the openness of the digital control system and realizes the complete software of the digital control system. The standardized controlling machine configures corresponding control resources according to the control process flow for preparing control information and decouples the system structure of the control system to control information generating part, control information distributing and sending part and control information executing part. The controlling machine not only has rich hardware and software resources of the PC, friendly man-machine interface and full-open network platform, but also has the standardization and low cost of the PC so that the controlling machine is an ideal structure for modern digital control systems and embodies the core value of the open digital control system.
