CMMS : How to connect sensors ( IoT - internet of things ) ?
The use of sensors (IoT) in new machines and components is becoming more and more widespread. At the dawn of Industry 4.0, an increasing number of industrial sectors are using sensors, connected controllers and other data collection systems for real-time equipment information retrieval.
This information may have an impact on the way in which you manage your maintenance tasks, whether in terms of scheduling equipment maintenance, analysing data cross-referenced with information from you maintenance management software, or responding to real-time alerts.
So how does this work?
All you will need to do is decide which sensor you want to use, depending on the type of data you wish to retrieve (such as the temperature or flow rate, for example). The most recent generations of sensors are upgradable and on-line, allowing you to store information and send it to a database, either within your own company or in the component manufacturer's private cloud. Once this information is accessible, all you will need to do is use Mobility Work software's APIs. A API is simply a connector that can transmit or retrieve data from your maintenance management software. Fitting this connector is straightforward: it only takes a few minutes and will cost you nothing over and above your Mobility Work licence fee. Once your data has been sent to the Mobility Work API, you will be able to set up automatic actions in your maintenance management software, such as create maintenance tasks or activate maintenance schedules.
Transferring your information will give you an enormous range of options, such as the ability to:
- Create a maintenance task in your CMMS when, for example, your temperature sensor measures a value above 35 degrees
- Issue an alert to an engineer in the CMMS when, for example, an oil level falls below the nominal recommended value
- Collect data on a machine's operating periods and integrate it into your maintenance software, allowing you to measure your equipment's MTBF and failure rates
- Activate a maintenance schedule based on an actual operating time for a piece of equipment rather than a calendar
- Issue an alert based on your spare parts stock in the CMMS
This data can be collected from various components:
- Pneumatic pressure threshold sensors
- Fluid proximity sensors
- Leak detectors
- Capacitive sensors
- Inductive sensors
- Optical sensors
- Incremental rotary encoders
- Absolute rotary encoders
- Position sensors
- Reed switch sensors
- Cylinder reed switches
- Strain gauges
- Pressure sensors
- Angular speed sensors
- DC analogue generators with a moving coil or iron core collector
- DC analogue generators without a collector
- AC analogue generators
- Industrial APIs, etc.
Custom fields can also be added to the equipment forms and can be completed with values from the sensors (IoT). This allows maintenance engineers to view real-time equipment information on their smartphones and make the right decisions.
Finally, cross-referencing data from Mobility Work with information from sensors in the analytics module will provide more detailed analyses of your equipment and detect anomalies based on particular tendencies. Anything is possible and the programming is straightforward: the only hard work involved is deciding what to measure.
