MQTT

What is MQTT Used For in IOT?

MQTT is short for MQ Telemetry Transport, and is a messaging protocol used in the Internet Of Things (IOT) systems.

It is  very simple and lightweight messaging protocol, designed for devices with limited processing power and low-bandwidth, high-latency or unreliable networks.

MQTT was designed  to minimise network bandwidth and device resource requirements, whilst also attempting to ensure  data delivery reliability and some degree of assurance of delivery.

The MQTT protocol ideal for Internet of things (IOT)  “machine-to-machine” (M2M) devices.

This is because  bandwidth and battery power are at a premium, in IOT equipment designs.

We can incorporate MQTT into custom equipment for our clients.

What Is Industry 4.0 & Smart Factories

industry 4.0

Industry 4.0

Industry 4.0 is a phrase that you will increasing hear in business manufacturing, but what exactly is it?

According to Wikipedia it is the following:-

“Industry 4.0 is the current trend of automation and data exchange in manufacturing technologies. It includes cyber-physical systems, the Internet of things and cloud computing. Industry 4.0 creates what has been called a “smart factory”. (Source: Wikipedia.com)

Why 4.0?

Industry 4.0 is often described as the Forth Industrial Revolution, so it would be useful to explain what Industry 1,2 & 3 were.

Industry 1.0

Industry 1.0 refers to the first industrial revolution that started around 1780.

The first industrial revolution was powered by water and steam, and was very mechanical in nature.

Industry 2.0

In 1870 the first electrically powered assembly line was introduced, and as the distribution of electricity become widespread, it opened up further opportunities for manufacturing.

This was the start of the era of mass production.

Industry 3.0

From the late 1960s onwards , computerisation started to be introduced into industrial processes.

This started with the Modicon 084 , which was the first PLC, which is short for Programmable Logic Controller.

A PLC is basically an industrial computer, used to control production processes.

By using PLC control, factories were able to improve efficiency, and save time and money.

An example of how a PLC did (and still does) save money is  that the program software can be easily changed and modified, to adapt to manufacturing requirements.

Prior to PLC control, you would need to redesign, and rewire large parts of your factory plant, to carry out the new process.  This was both time consuming , and expensive to do.

Industry 4.0

The latest revolution in manufacturing involves  minimal intervention & involvement by human beings.

Instead what is often described as ‘machine learning’ takes place, where algorithms make decisions based on live input data.
