When the Machine Replaces Human Technology & Change Human Life

Long ago, mankind had a long history of applying automation technology. Ancient Egyptians invented a water-powered "water bell," ranking the world's most accurate timepiece throne for two thousand years, is the human record of the application of automation technology at the beginning.

It was not until the eighteenth century that the automated control system used in the windmills inspired Watt to invent the steam engine, which led to the first industrial revolution, which greatly subverted the customary modes of production for thousands of years and led to the replacement of manual The era of labor.

Automated technologies have made manufacturing industries more efficient and have a direct impact on people's lives. Nowadays we have access to convenient transportation, ready to receive messages from all over the world and have a diverse range of consumer choices, And automation technology innovation is closely related.

And recently, the fourth wave of the industrial revolution has already started. In the trend of smart factories and intelligent robots, automation technology still plays an indispensable and crucial force. This article will introduce the development of automation technology-related industries, a glimpse of the industry links and future trends it derives.

What is Automation?

In a broad sense, Automation is defined as a task that is difficult to accomplish by human beings, using resources other than human resources, such as mechanical, hydraulic and electric power, instead of mankind to manipulate, control and monitor equipment or programs.
It can effectively save manpower and time, reduce the chance of human error, reduce personnel exposure to the dangerous environment, and improve product quality. Automation covers a wide range, in addition to all walks of life machines and auxiliary equipment, but also in daily life everywhere, small home to automatically cook electric cookers, convenience stores, automatic doors, large building air-conditioning control and elevators, MRT automated system, all belong to the automation application.

Narrowly defined in the industrial automation, it refers specifically to the use of the mechanical, electronic and computerized system to control and production technology. Mainly includes the production of components of the automated machine tools, logistics and storage systems, quality control testing, data collection and feedback and computer process control.

Automated system

If we are to understand the technology of automation, we must dismantle the complex automation system, starting from the most basic unit to recognize. In the mechanism of the automation system, the automation control element is the smallest unit that functions in the automation system. A closed-loop automation system mainly consists of the following four elements.

Controlled body Refers to the system in the receiving command, controlled passive parts, similar to human organs, muscles, joints. For example the jaws at the end of a robot arm.

Sensor to detect, perceive the outside signal, physical conditions or chemical composition, and the signal is passed to other parts, similar to the human organs nerves. Such as image sensor, temperature sensor.

Controller After the signal transmitted by the sensor is transmitted to the controller, it is calculated through the algorithm in the controller and sends the processed signal to the driver, which is similar to the brain of a human organ. For example, programmable logic controllers

(PLCs), industrial computers.

Actuator The power source that drives a mechanical action, similar to the heart of a human organ. For example linear motor, a pneumatic cylinder.
