Multi-module assembly in control system and method of securing plurality of modules

Abstract

The embodiment of the invention relates to a multi-module assembly in a control system and a method for fixing a plurality of modules. The multi-module assembly includes: a plurality of modules, each module including at least one heat dissipation hole disposed at a respective distal end; a base plate to which the plurality of modules are fixed at respective proximal ends; and at least one auxiliary fixing device, each auxiliary fixing device being coupled to one module of the plurality of modules through the heat dissipation holes of the one module, and being coupled to another module of the plurality of modules through the heat dissipation holes of the other module, and the far end of one module is fixedly connected with the far end of the other module across the gap between the module and the other module. According to the embodiment of the invention, the auxiliary fixing of a plurality of modules can be realized in the control system in a low-cost, simple and easy-to-operate manner, so that the unexpected vibration is inhibited.

Description

technical field [0001] Embodiments of the present disclosure relate to the field of industrial control, and more particularly, to a multi-module assembly in a control system and a method for securing a plurality of modules in a control system. Background technique [0002] In control systems for industrial control, it is often necessary to use assemblies with multiple modules. An example of such an assembly with multiple modules is an IO module assembly, which is used to interface the input and output between the controller and external devices, and common IO module assemblies provide multiple IO modules to meet the needs of the control system. [0003] These modules, such as IO modules, usually have a certain length and width, and sometimes take on a flat shape. When installing an assembly with such modules in a control system, for example, a plurality of modules can be fastened adjacent to each other and spaced apart from each other. For general working conditions, the ...

Problems solved by technology

However, under some operating conditions (such as ships, vehicles, etc.), the control system including such components may be subjected to relatively severe vibrations, which may cause the module (such as an IO module with a long and flat structure) itself Shaking and collisions between modules or between modules and other equipment may even lead to module damage and failure in some cases, thereby affecting the operation of the control system
