What is the Things Network

The Things Network is a worldwide crowd funded Internet Of Things Network, which started in Amsterdam.

It consists of sensors, such as air quality sensors that transmit data wirelessly via ‘Gateway’ devices to the Internet Cloud.

It is rapidly expanding around the world, including the UK.

Why do we need this network?

The world is undergoing rapid change in the world of work, and it has been predicted that many jobs will become automated in the coming years.

The Internet Of Things, or IOT for short, along with Virtual Reality & 3D Printing  is part of this new industrial revolution.

It is therefore vitally important that we educate the current and future generations quickly, so we don’t get left behind as a nation.

The Things Network helps educate people, and lets businesses cost effectively develop new IOT products.

Where DoesThe Lincoln Network Cover

The Things Network is based on a wireless technology called LoraWAN.

As with all wireless technologies LoraWAN, which the Things Network runs on is range limited.

One of the great features of LoraWAN technology is that the signal can travel a long distance, using low power.

However as with all wireless technologies, buildings and natural objects in ‘line of sight’, will reduce the signal range.

The Things Network uses devices called ‘Gateways’ to receive the signals transmitted wirelessly from the remote sensors, and puts the data onto the web.

Currently the Lincoln Things Network has planned to install one Gateway near central Lincoln.

This should cover a large area of the City of Lincoln, but other additional Gateways may well be necessary, due to objects, reducing the signal coverage.

When will the Network be live

The components for the first Gateway device for the Lincoln Network has been ordered, and the plan is to go live by December 20th in the Lincoln area.

As the Things Network is eseentially a voluntary community effort, we welcome help from schools and local businesses.

Please get involved, as any help is appreciated.

The Lincoln Things Network was initiated by Craig Miles, who can be contacted via the community page at https://www.thethingsnetwork.org/community/lincoln/

Retrofitting the Internet of Things to Industry

Things to Consider When Retrofitting the Internet of Things to Existing Industrial Equipment

 

The Internet of Things, or IOT for short is already known to the public through innovative products, such as body worn fitness monitors, that record and upload data to the internet.

In the industrial sectors, such as manufacturing, new systems are being developed to replace existing infrastructure, to improve efficiency.

However, what about perfectly good existing equipment that you, as a business, do not want to replace. The answer is to retrofit equipment, to make it ‘Smart’.

It is convenient to break down the IOT process in terms of:-

 

Input-Process-Output

 

Therefore retrofitting the Internet of Things….tb continued

 

 

This is the first of our videos on retrofitting the Internet of Things to existing industries, such as factories, agriculture and cities.

Star-Delta Starter Adaption for The Internet Of Things

star delta starter modifications for IOT
star-delta starter

Star-Delta Starters are used to start larger ac induction motors used in industries,such as Manufacturing and Marine.

Like ‘Direct Online’ (DOL) starters, which are also used for ac induction motors starting (though smaller, lower current motors), Star-Delta starters only turn the motor on and off at a single speed.

With the growth in the internet of things, industries, such as Mining and Marine Click To Tweet (who use Star-Delta starter systems) need to consider how to keep their business efficiency as good as their competitors.

Competitors are always seeking competitive advantage. This can be achieved through cost and efficiency savings, and IOT (Internet of Things) connectivity allows close monitoring of system processes, and so called ‘machine learning’.

In the case of a Star-Delta motor starter, there area number of outputs that we may wish to measure using sensors.

Firstly, the current being drawn by the Star-Delta starter. This includes both the starting (or In rush) current, and the FLC (Full Load Current).

Monitoring of the Full Load Current (FLC) for example is useful because an increase in current been drawn through a phase, might be due a break in one of the other phases. This causes what is known as ‘Single Phasing’ to occur.

Single Phasing can potentially damage both the motor windings and cabling from the starter to the motor, due to current doubling in the two phases still connected.

The motor windings for example, would not be designed to handle the excess current flowing through the two (still) connected ones, potentially causing damage, expense and downtime.

The Star-Delta Starter normally has a current limiting device installed, called an Over Current Relay (OCR).

There are three types of OCR, Electronic, Magnetic, and Thermal.

The OCR will detect higher than normal currents, caused for example by ‘Single Phasing’.

When single phasing is detected by the OCR, it will disconnect the three phase supply going to the induction motor (after short delay, dependent on over current size).

To be continued………

Its a brilliant idea, and I think that this will really help businesses and the general public develop products using the Internet of Things that will improve this world for the better.

 

For enquiries about the Lincoln Things Network, contact me via the page link above, rather than through Yesway, which is not connected with the network. I just happen to work for Yesway, and are also personally the Things Network initiator for Lincoln.

The two are separate, and I am only putting the details on the yesway site to spread publicity to our social media subscribers, so that more people know about this great free idea.

 

Challenge of Installing IOT Sensor Equipment in Explosion Proof Areas

Challenge of Installing IOT Sensor Equipment in Explosion Proof Areas, by Craig Miles

IOT, or the Internet of Things is already changing the way that businesses function, and this is set to explode in the forthcoming years.

IOT is all about improving business efficiency by collecting information (via sensors) about the physical world (Inputs such as: temperature, pressure, location etc), and then using this data to trigger an automated action, based on the data.

Installing the sensors that provide the ‘inputs’ to your IOT system is usually fairly straightforward in most environments, however potentially explosive environments require special considerations.

When installing any electrical or electronic device in a potentially explosive environment, the device must be rated as ‘EX’ , also known as ‘intrinsically safe’.

Intrinsically safe electrical equipment is available as components such as electric fans, cable glands, and hand-held two-way radios.

This is a business opportunity for IOT device manufacturers to create ‘EX’ rated sensors.

The main thing to consider at all times when designing your install, is will my equipment cause a spark, potentially causing an explosion.

First consider your sensor itself. An example is a sensor located in a ships battery room to monitor and report on voltage and specific gravity of the lead acid batteries, used for emergency backup.

The sensor you use to collect the information MUST be EX rated / intrinsically safe, to be compliant.

The next consideration is how you are going to get the data from the sensor ‘out’ of the potentially explosive area and to the location where the data is processed.

Wireless technologies such as Zigbee, WIFI and LORA could be used, but by definition produce RF radiation which could potentially cause an explosion. Therefore it is crucial that only equipment that is EX rated is used.

In the case of environments hostile to RF (Radio Frequency) Radio Waves, such as ships, oil rigs and other buildings high metal content, an alternative would be a fixed wired solution.

When using wired methods to transmit sensor data, the cable glanding must be designed so that the explosive area remains gas tight, to prevent explosive gases interacting with electrical components outside the intrinsically safe area.

Glands for this purpose exist, and can be found online.

To conclude, the key to installing the Internet of Things (IOT) in a potentially explosive environment is to ensure that every piece of IOT equipment that is installed is EX rated to prevent explosion risks.

You also need to think about and ensure that any wiring that leaves the intrinsically safe / explosive area goes through properly rated EX glands, to ensure safety.

The Internet of Things (IOT)

The ‘Internet of Things’ is a term that is due to become more widely known during 2014.

One application of the Internet of Things, or IOT, is smart vending machines. For example the machine would know when it had run out of mars bars.

It would the automatically send this data to a central database, which would automatically contact a delivery driver in the field. The driver could be instructed to change his delivery route, and go to replenish the mars bars in that empty vending machine.

This is just a fraction of how machines will automatically communicate with other machines, and even with people (the delivery driver for instance).
