Let's take a look at what exactly is an automated factory standard?
In industrial production, the degree of automation of automation is getting higher and higher. Today, Xiao Bian and everyone take a look at the standard of an automation factory.
1, the controller
Automation factory brain
The controller (English name: controller) refers to a master command device that changes the main circuit or the control circuit wiring in a predetermined order and changes the resistance value in the circuit to control the start, speed, brake, and reverse of the motor.
It consists of a program counter, an instruction register, an instruction decoder, a timing generator, and an operation controller. It is a "decision making agency" that issues commands, that is, the operation of coordinating and directing the entire computer system.
@ Controller is a device that controls the transfer of data from a computer to a peripheral device and vice versa. For example, disk drives, display screens, keyboards, and printers all require controllers.
Plc (programmable controllers), industrial computers, etc. are commonly used in automation plants.
Programmable logic controller (PLC), which uses a type of programmable memory for its internal stored procedures, perform logic operations, sequence control, timing, counting and arithmetic operations and other user-oriented instructions, and through Digital or analog input/output controls various types of machinery or production processes.
2, robot
Performer in an automated factory
Robot, a robot is a machine device that performs work automatically. It can accept human command, run pre-arranged procedures, or act according to the principles set out by artificial intelligence.
Its task is to assist or replace human work, such as production, construction, or dangerous work. Robots generally consist of actuators, drives, detection devices and control systems, and complex machinery.
The robots consist of actuator, drive, complex mechanical testing device and control system.
3, servo motor
Power muscles in automated factories
A servomotor is an engine that controls the operation of a mechanical component in a servo system and is an auxiliary motor indirect transmission.
The servo motor can control the speed and position accuracy very accurately. It can convert the voltage signal into torque and speed to drive the control object.
Servo motor rotor speed is controlled by the input signal, and can react quickly. In the automatic control system, it is used as an actuator. It has characteristics such as small electromechanical time constant, high linearity and starting voltage, etc., which can receive the electrical signal. Convert to angular displacement or angular velocity output on the motor shaft.
Divided into two major categories of DC and AC servo motor, its main feature is that when the signal voltage is zero there is no rotation phenomenon, the speed decreases with the increase of torque and uniform speed.
@ A servomotor is a rotary actuator or linear actuator that allows for precise control of angular or linear position, velocity and acceleration.
It consists of a suitable motor coupled to a sensor for position It also requires a relatively sophisticated controller, often a dedicated module designed specifically for use with servomotors.
4, the sensor
Automation Factory Touch
The sensor (English name: transducer/sensor) is a detection device that can sense the information to be measured, and can transform the sensed information into electrical signals or other desired forms of information output to satisfy the information. The requirements for transmission, processing, storage, display, recording and control.
It is the first link to achieve automatic detection and automatic control.
In modern industrial production, especially in the automated production process, various sensors are used to monitor and control various parameters in the production process so that the equipment can be operated in a normal state or an optimal state, and the product can achieve the best quality. Therefore, it can be said that without numerous excellent sensors, modern production loses its foundation.
@ A transducer/sensor is a device that converts one form of energy to another. Usually a transducer converts a signal in one form of energy to a signal in another.
Using sensor to monitor and controll parameter of production process to make sure device operating with best condition and producing high quality products.
5, frequency converter
Automation factory switches
Variable frequency drive (VFD) is the application of frequency conversion technology and microelectronics technology to control the AC motor power control equipment by changing the frequency of the motor power supply.
The inverter is mainly composed of rectification (AC to DC), filtering, inverter (DC to AC), brake unit, drive unit, and detection unit micro-processing unit.
The inverter adjusts the voltage and frequency of the output power supply by breaking the internal IGBT, and provides the required power supply voltage according to the actual needs of the motor, thereby achieving the purpose of energy saving and speed control. In addition, the inverter has many protection functions. , such as over-current, over-voltage, overload protection and so on.
@ A variable-frequency drive (VFD) is a type of adjustable-speed drive used in electro-mechanical drive systems to control AC motor speed and torque by varying motor input frequency and voltage.
6, solenoid valve
Automatic factory switch
An electromagnetic valve is an electromagnetically controlled industrial device. It is an automated basic element used to control fluids. It is an actuator and is not limited to hydraulic and pneumatic.
It is used to adjust the direction, flow rate, speed and other parameters of the media in the industrial control system. Solenoid valves can be combined with different circuits to achieve the desired control, and the control accuracy and flexibility can be guaranteed.
There are many kinds of solenoid valves. Different solenoid valves play a role in different positions of the control system. The most commonly used ones are check valves, safety valves, directional control valves, and speed control valves.
@ This allows fuel to be shut off from the sprayer by electrical control. It avoids drips when the valve is closed. It also eases the purging of the burner (and any boiler) of fuel mist during the start up, or while restarting after a Misfire.
7, industrial camera
Automated factory glasses
Industrial cameras are a key component of the machine vision system. Its most essential function is to convert optical signals into ordered AFT-808 industrial high-definition industrial cameras.
The industrial camera is generally installed on the machine assembly line instead of the human eye to make measurements and judgments, and is converted into an image signal through a digital image capture target and transmitted to a dedicated image processing system.
The image system performs various operations on these signals to extract the characteristics of the target, and then controls the equipment operation in the field according to the result of the discrimination.
@ The term "industrial cameras" is a little bit misleading since these cameras are not only used for machine vision but also for medical, scientific and security purposes.
The following sections outline the typical features of industrial cameras.
8, instrumentation
Automatic factory conditioning system
Instrumentation (instrumentation) Instruments and meters are instruments or devices used to detect, measure, observe, and calculate various physical quantities, material compositions, and physical properties. Vacuum leak detectors, pressure gauges, length gauges, microscopes, multipliers, etc. all belong to the instrument.
In the automated factory, various instruments and meters are needed. For example, measuring parameters such as pressure, liquid level, flow rate, and temperature, etc., requires related instrumentation.
@ Instrumentation is the development or use of measuring instruments for observation, monitoring or control.
Instruments may be as simple as direct reading hand-held thermometers or as complex as multi-variable process analyzers.
9, automation software
Heart of automated factory
Automation Software, due to the industrial control system's integration of management and control trends, enables industrial control systems to communicate with traditional IT management systems and the Internet. Internal software is increasingly used as general-purpose software, general-purpose hardware, and general-purpose protocols. The more common is the SCADA automation software.
SCADA automation system (supervisory control and data acquisition) is what we call data acquisition and monitoring system. It is mainly a system supported by computer technology and automatic control of various production processes.
The SCADA automation software can automate accurate monitoring of production for long periods of time under unattended conditions, and obtain valid information data from it, providing a powerful evaluation reference for supervised managers.
@ SCADA (supervisory control and data acquisition) is a system for remote monitoring and control that operates with coded signals over communication channels (using typically one communication channel per remote station).
The control system may be combined with a data acquisition system by adding the use of coded signals over communication channels to acquire information about the status of the remote equipment for display or for recording functions.
