An automated complete control system is an integrated system that combines automation technology, computer technology, communication technology and other technologies to realize automatic monitoring, control and management of production processes, equipment or systems. The following is a detailed introduction from the aspects of its composition, functions, application scenarios, etc.:
System composition
Controller: As the “brain” of the system, it is usually composed of a programmable logic controller (PLC), an industrial computer, a distributed control system (DCS), etc., responsible for processing and analyzing the data in the system and issuing control instructions according to preset rules and algorithms.
Sensor: Equivalent to the “eyes” and “ears” of the system, it is used to monitor various physical quantities of the system in real time, such as temperature, pressure, flow, position, etc., and convert these physical quantities into electrical signals or other signals that can be recognized by the controller.
Actuator: As the “hands and feet” of the system, it performs specific operations according to the instructions issued by the controller, such as motors, valves, cylinders, etc., to realize the control of the controlled object.
Human-machine interface (HMI): It is the interface for operators to interact with the automation system, which can display the operating status and parameter information of the system, etc. Operators can also set parameters and issue operation instructions through HMI.
Communication network: used to realize data transmission and communication between various components of the system, so that controllers, sensors, actuators and HMI can work in coordination with each other, such as industrial Ethernet, fieldbus, etc.
Main functions
Automatic control function: can automatically adjust the operating state of the controlled object according to the preset control strategy and algorithm, so that the output of the system remains within the desired range, such as achieving stable control of parameters such as temperature and pressure.
Data acquisition and processing function: can collect data from various sensors in the system in real time, and analyze, process and store these data to provide a basis for system operation monitoring, fault diagnosis and optimization decision-making.
Monitoring and alarm function: through the human-machine interface or monitoring software, the operator can monitor the operating status of the system in real time. When the system is abnormal or fails, the system can send an alarm signal in time to remind the operator to take corresponding measures.
Optimization and management function: some advanced complete automation control systems also have optimization functions, which can automatically adjust control parameters and operation strategies according to the system’s operating data and production requirements to achieve optimized operation of the system and rational use of resources.
Application scenarios
Industrial production: such as automobile manufacturing, chemical industry, steel, electric power and other industries, used for automatic control of production lines, optimization of process flow, operation monitoring of equipment, etc., to improve production efficiency, product quality and production safety.
Smart building field: used for lighting control, air conditioning system control, security system control, etc. of buildings, to realize intelligent management of buildings and provide a comfortable, energy-saving and safe environment.
Transportation field: such as signal control of rail transit such as subway and light rail, automatic train driving system, and traffic signal control and intelligent parking management in intelligent transportation system.
Agriculture field: used for environmental control of greenhouses, automatic control of irrigation systems, remote monitoring of agricultural production equipment, etc., to improve the automation level and resource utilization efficiency of agricultural production.
Automated complete control systems can realize automatic management and control of complex systems through the collaborative work of various components, improve production efficiency, reduce costs, improve product quality and service level, and play an important role in the development of modern industry and society.
