We have the new Minew P1 Plus in stock. It’s a sensor beacon designed for rough environments and is IP68 waterproof, IK09 shockproof and has a wider than normal temperature rating due to use of the included industrial ER14250H lithium battery.
This beacon has temperature and accelerometer sensors. It’s turned on and off via a magnetic switch. As with other Minew beacons it advertises up to 6 channels that can be iBeacon, Eddystone UID, Eddystone URL, Eddystone TLM and device info.
The Fourth Industrial Revolution, also known as 4IR and Industry 4.0, improves manufacturing through the use of technology. The end-aims are to significantly improve productivity, reduce production delays and, for example, avoid penalties or future lost orders due to delayed work.
A key part of The Fourth Industrial Revolution is asset tracking that provides faster and more accurate stock control, item picking, job tracking, capacity measurement, demand analysis and product protection through sensing and automatic auditing.
It’s important that asset tracking is continuous because merely scanning things in/out using barcodes is open to human error and location is otherwise only as good as the last scan. Historical data is also important because it identifies blockages allowing processes to be refined.
When evaluating asset tracking systems consider:
Look for a stand-alone solution rather than SAAS for greater performance, flexibility and longevity. While SAAS based systems can be a quick way into RTLS, they soon become limiting because you are sharing a platform with other customers. SAAS platforms usually don’t scale well technically and financially and don’t have efficient, direct access to the data for efficient ad-hoc reporting. They also pose potential security and reliability risks as you don’t own your data. The ultimate limitation comes when the SAAS provider, usually a startup, eventually increases costs, get’s bought out by its largest customer or goes out of business.
It’s interesting how many of our clients come to us with a problem to solve and in talking through possible solutions they often suddenly have the thought, ‘That’s IoT isn’t it?’. They weren’t looking for an IoT or Industry 4.0 solution but they got there by a different route. Indeed, it’s always best to start by solving problems rather than trying to fit technology into existing processes.
So what are the typical problems in factories? While companies usually have systems to take orders and invoice for them, what goes on in between is often a manual paper process. Knowing where an order is physically and hence how far it has been completed often requires lots of ringing round. Similarly, there are usually problems finding parts for jobs. Parts arrive in boxes or in pallets and are stored somewhere pending jobs. Finding the right pallet or box on a large site can be a challenge. It might be in storage, already on the factory floor somewhere or in transit between areas. Sometimes, delicate parts might be left in the wrong places and spoil due to excess humidity or in some cases incorrect temperature. Expensive tools and equipment tends to be shared between work areas and this can also get mislaid, lost or stolen.
All these problems cause delays in production, reduced productivity, incur penalties or future lost orders due to delayed work and cause employee frustration.
The solution is to better track jobs, parts, sub-assemblies and shared valuable tools so that they can be located on factory plans. This tracking needs to be continuous and real-time because merely scanning things in/out using barcodes is open to human error and location is otherwise only as good as the last scan. Historical data shows where things have been in the past. Analysis of this data allows blockages to be identified so that the process as a whole can be refined to improve efficiency and production.
The result is reduced downtime, less time re-ordering or re-making things that have been lost, optimum productivity and better use of skilled staff doing their job rather than searching for things.

Beaconzone founder, Simon Judge, has posted a new article on Linked on Improving Factory Productivity in the Age of Covid-19. It takes a look at how factories are needing to scale up (or down) while, at the same time, maintaining social distancing.
Digitising manual production lines provides visibility through the use of contact-less measurement that can be used to improve productivity. The article explains how to get started.
A common problem in factories is manual searching for stock for input to manufacturing. Stock is usually stored in boxes or pallets and can be in one of many rooms, warehouses or might already be somewhere on the factory floor. A large amount of stock arrives and leaves every day leading to logistical challenges keeping up with the whereabouts of goods. Timely delivery of components or sub-assemblies is critical to ensure smooth flowing of production and making best use of factory resources.
Manual paper-based processes are extremely inefficient and prone to human error. Old fashioned RFID or barcodes are also susceptible to error because data is only as up to date as the last scan and a recent scan might not have occurred.
Bluetooth is an ideal technology for solving this problem because it provides real-time location. We previously wrote about the advantages of using beacons in industry and how Bluetooth is suitable for use on the electrically noisy factory floor.
We offer multiple solutions for tracking stock and can adapt them to your exact needs, for example integrating with your existing systems. Once you have a tracking system in place you can use it for extra purposes such as locating jobs/work orders, monitoring machine/people capacity and providing for location based instruction/tasks. Sensing open/closed, on/off and quantities such as temperature and vibration enables diagnostics, monitoring and prognostics.

Ignition is a HMI/SCADA system used for factory machine control and monitoring. It uses web-based technology running on an on-site server. It’s configured using a drag and drop user interface to provide HMI/SCADA controls, dashboards, historical trending, database access, reporting, alarming, security, sequential function charts, redundancy and failover control.
Ignition 8.0 has support for Bluetooth in the Perspective App running on mobile devices. It reads iBeacon and Eddystone formats. This allows for functionality based on location.

There’s an informative video presentation on the Bluetooth SIG web site on Simplifying Multi-Vendor Mesh and Sensor Networks. It provides an introduction to Bluetooth mesh and explains the ways in which it can provide for Industrial IoT (IIoT).
To add to this, Bluetooth Mesh is suitable for use on the factory floor where the environment can be electrically noisy. Standard Bluetooth Mesh uses advertising on several channels rather than (GATT) connections so as to provide for more reliable communication in environments with wireless interference.

U-Blox has a useful article on Seven reasons why Bluetooth is perfect for the Industrial IoT, echoing some of our observations on Bluetooth LE on the Factory Floor. The article explains why Industrial Internet of Things (IIoT) systems and networks should consider Bluetooth as the communications infrastructure.
As U-Blox mentions, there’s predicted to be 5.2 billion Bluetooth device shipments by 2022. This data is from the latest Bluetooth SIG/ABI research:

There’s lots said about the advantages of Industry 4.0 or Digital Transformation and the associated new technologies but it’s a lot harder to apply this to the context of a business that has legacy equipment and no real way of knowing where to start.
Our previous article on productivity explained how, historically, digital transformation has been only been implemented in the top 5% ‘frontier’ companies. These have tended to be very large companies with large R&D budgets that have enabled customised digital solutions. More recently, the availability of less expensive sensors and software components have extended opportunities to the SME companies. These companies are already realising gains in profitability, customer experience and operational efficiency. Unlike previous technologies, such as CRM, the newer technologies such as IoT and AI are more transformative. Companies that don’t update their processes risk being outranked by their competition with a greater possibility of going out of business. But where do you start?
The place to start is not technology but instead something you and your colleagues fortunately have lots of experience of : Your company. Take an honest look at your processes and work out the key problems that, if solved, would achieve the greatest gains. You might have ignored problems or inefficiencies for years or decades because they were thought to be insolvable. Technology might now be able to solve some of these problems. So what kind of problems? Think in terms of bottlenecks, costly workrounds, human effort-limited tasks, stoppages, downtimes, process delays, under-used equipment and even under-used people. Can you measure these things and react? Can you predict they are about to happen? This is where sensing comes in.
The next stage is connectivity. You will almost certainly need to upgrade or expand your WiFi and/or Ethernet network. It can be impractical to put sensors on everything and everyone and connect everything by WiFi/Ethernet. Instead, consider Bluetooth LE and sensor beacons to provide a low cost, low power solution for the last 50 to 100m. Bluetooth mesh can provide site-wide connectivity.
Initially implement a few key improvements that offer good payback for the effort (ROI). The improvements in efficiency, productivity, reduced costs and even customer experience should be enough to convince stakeholders to expand and better plan the digital transformation. This involves replacement of inefficient equipment and inefficient processes using, for example, robotics and 3D printing. It also involves analysing higher order information combined from multiple sources and using more advanced techniques such as AI machine learning to recognise and detect patterns to detect, classify and predict. This solves problem complexity beyond that able to be solved by the human mind or algorithmic program created by a programmer.

Tracking loaded pallets saves a significant amount of time, effort and hence cost in logistics and manufacturing. Pallets might contain stock, components or sub-assemblies. The top usecase is finding a particular pallet quickly. However, sensing need not be limited to pallets. Extending tracking to forklifts, racking and even people provides additional business benefits. For example, we have previously been asked to provide for the following scenarios:
“I need to ensure best use of my forklifts. Tell me when one hasn’t moved for 2 minutes.”
“I need to know if a forklift has crashed into racking.”
“I run a warehouse containing hazardous materials. If evacuation is needed, I need to know everyone has evacuated the building even if someone has temporarily gone off site”
These situations, and more, are solvable using Bluetooth beacons (In terms of asset tracking, beacons are sometimes called tags).
RFID and barcodes can also be used for tracking. However, the information is only as good as the last scan that might have been a long time ago after which the asset might have moved without being scanned. The advantage of beacons is that they repeatedly advertise so the information is always up to date.
Further advantages of Bluetooth tags are:
Software such as our BeaconServer™ and BeaconRTLS™ can be used to track what’s where over time, create notifications and integrate with your existing systems.
Once you have some current and historical data you can also start to do clever things such as automatically detecting and predicting over or under utilisation, finding pinch points or detecting valuable equipment about to be stolen.
