Problems solved by technology

[0004] Because multiple main control units share the same physical communication link with the acquisition and control object (equipment) for data acquisition and control, they cannot effectively perform coordinated control, resulting in communication failures and unable to realize remote monitoring and control of the object (equipment)
Most of the main control unit collaboration on the market adopts two-machine collaboration, and has not fully accumulated technical know-how in multi-machine (two or more) collaboration

Embodiment Construction

[0026] Embodiments of the present invention are described in detail below, examples of which are shown in the drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below by referring to the figures are exemplary only for explaining the present invention and should not be construed as limiting the present invention.

[0027] Below in conjunction with accompanying drawing, technical scheme of the present invention is described in further detail:

[0028] Due to the physical characteristics of the communication link itself and the constraints of data transmission specifications, there is no automatic switching of the main and backup links that can be completed by the communication link itself. Therefore, a coprocessor (or processing process) independent of the communication link is required to complete the monitoring of the link status and instruct the com...

Abstract

The invention discloses a distributed control method for main control units. According to the control method, when a plurality of main control units (two or more than two) main control units cooperatively acquire and process data, a primary acquisition control unit is determined through the automatic control decision process. When the main control units process an acquisition control object (equipment), cooperative control is carried out by taking the object (equipment) as a unit, so that load balancing in the running process can be achieved. When the main control units fail, any one standby control unit can automatically succeed an acquisition control task. When a conflict occurs, a control unit in a subordinate position can be automatically degraded into a standby control unit.

Description

technical field [0001] The invention discloses a distributed control method for a main control unit, in particular to an industrial acquisition device and a control method thereof, and relates to the technical field of multi-machine distributed control and automatic balance decision-making process among multiple machines. Background technique [0002] Industrial equipment used in industrial environments for user data acquisition and control is called a master control unit. The main control unit has the functions of network, serial port, field bus port and other physical communication links to communicate with industrial acquisition and control objects (equipment), obtain data, and issue control instructions. [0003] When there are more than one main control unit facing the same collection and control object (device), each main control unit will share the same physical communication link with the collection and control object (device) for data collection and control. Under ...
