Problems solved by technology

While a decentralized Controller Area Network (CAN) architecture offers such benefits, using the architecture suffers from the costs associated with each controlled component having its own electronics, including digital signals configured with Processor's printed circuit board assembly, Controller Area Network (CAN) communication hardware, current drivers, and possibly sensors

Embodiment Construction

[0011] Referring now to the drawings, similar elements are identified by similar reference numerals throughout several views in the drawings, figure 1 A block diagram of a control system network architecture 100 used in a fluid control system according to a first example embodiment of the present invention is shown, such as but not limited to hydraulic control systems, pneumatic control systems, and other control systems. The control system network architecture 100 (sometimes referred to herein as the "architecture 100") can be used in a variety of fluid control systems / used with a variety of fluid control systems to control the delivery and distribution of appropriate fluids to various recipients. Control endpoint device 102. As used herein, the term "fluid" means and refers to incompressible fluids or compressible fluids (such as but not limited to hydraulic fluid, oil, air, and water) that are delivered or distributed in a controlled manner in response to receiving such The ...

Abstract

The present disclosure describes a control system network architecture for a fluidic control system such as a hydraulic or pneumatic control system. The architecture comprises a plurality of clusteredcontrol-component nodes with each node being alternatively configurable to independently control the operation of multiple single-acting controlled endpoint devices or a double-acting controlled endpoint device. Each node comprises control-components including a solenoid, a plurality of valve spools independently controllable by the solenoid, and a low-level controller operable to control the solenoid. The solenoid, valve spools, and low-level controller are clustered together and physically co-located as a unit. The nodes are arranged in a control block with each node being uniquely identifiable for data communication via a data communication network. The data communication network may comprise a Controller Area Network (CAN). Multiple control blocks may be equipped with communication modules and linked for data communication between control blocks.

Description

Technical field [0001] The present invention relates generally to the field of control systems, and more specifically, to control system network architectures for fluid control systems such as hydraulic or pneumatic control systems. Background technique [0002] Nowadays, the operation of many hydraulic and pneumatic systems in vehicles, heavy equipment or other applications is controlled by a control system using a Controller Area Network (CAN). CAN has a centralized or decentralized architecture. In the centralized controller area network (CAN) architecture, the central controller of the hydraulic or pneumatic system presents information to the operator and receives input information from the operator through a human machine interface (HMI) device. The central controller also receives input information in the form of data collected by various sensors located in strategic locations of the system. Under the control of the software executed by the central controller and using the...
