In today’s IT landscape, there is a growing demand for fully automated industrial systems. The ubiquity of the Internet and advancements in embedded technologies have broadened the scope of web technology to include the development and application of embedded systems. Envision a future teeming with microcomputers integrated into home appliances, factory machinery, and beyond. In this scenario, the implementation of an embedded web server (EWS) is a wise decision.
Here are the essential aspects of embedded web servers for industrial automation:
- Definition and Purpose:
- An embedded web server (EWS) is essentially a microcontroller equipped with an Internet software suite and application code for monitoring and controlling systems.
- Its primary purpose is to facilitate communication between devices and remote locations via the Internet.
2.Project Overview:
- A specific project discussed in a research paper involves using a personal computer (PC) with an Ethernet card to send messages to remote locations.
- These messages are received by a 32-bit ARM processor, which then controls devices in real-time.
- The project allows changing the status (ON/OFF) of any appliance connected to the ARM processor board via the Internet.
- Messages from the PC can be sent to any remote location worldwide using this technology.
3.Implementation Details:
- The project’s code is written in embedded C language, chosen for its simplicity and suitability for embedded system design.
- The focus is on monitoring and controlling the status of two devices.
- Clients can monitor and control the devices’ status (ON/OFF) via the Internet from anywhere in the world.
4.Industrial Applications:
- Embedded web servers find important applications in control systems for complex industrial equipment.
- These systems sense and accumulate data about device states and control their operations.
- Additionally, they provide device state information to operators and receive instructions from them.
Embedded web servers are vital in connecting industrial devices with remote access, facilitating effective monitoring and control.
