Abstract

automatic parking systems are a contemporary answer to the increasing number of cars and the limited number of free space available for purposes, especially in city areas. Savings in construction volume of up to 50% is characteristic for automatic parking systems based on their compact warehouse design, coupled with effective transport system. In this project, we will discuss the automation process of an automatic parking system. This system will be controlled by plc and scada. This system has been tested and worked well, so it is possible to apply this system nowadays. This results in incentives for individual solutions to parking space problems in city areas.

Automation plays an increasingly important role in the global economy and in daily experience. Engineers strive to combine automated devices with mathematical and organizational tools to create complex systems for a rapidly expanding range of applications and human activities. Automation (ancient Greek: = self dictated), roboticization or industrial automation or numerical control is the use of control systems such as computers to control industrial machinery and processes, replacing human operators. In the scope of industrialization, it is a step beyond mechanization. Whereas mechanization provided human operators with machinery to assist them with the physical requirements of work, automation greatly reduces the need for human sensory and mental requirements as well.

Specialized hardened computers, referred to as programmable logic controllers (PLCs), are frequently used to synchronize the flow of inputs from (physical) sensors and events with the flow of outputs to actuators and events. This leads to precisely controlled actions that permit a tight control of almost any industrial process. (It was these devices that were feared to be vulnerable to the "Y2K bug", with such potentially dire consequences, since they are now so ubiquitous throughout the industrial world.)
Human-machine interfaces (HMI) or computer human interfaces (CHI), formerly known as man-machine interfaces, are usually employed to communicate with PLCs and other computers, such as entering and monitoring temperatures or pressures for further automated control or emergency response. Service personnel who monitor and control these interfaces are often referred to as stationary engineers.
