Home Automation & Connected Car
New possibilities are also arising in the areas of home automation and the connected car. So for example in a house, a large proportion of the light switches could be dispensed with if sensors were to detect where people were. Such sensors also provide valuable input for the efficient control of heating.
At the same time, German car manufacturers are assuming that by the year 2020 at least every second new vehicle will be a connected car, that is to say a vehicle with a permanent Internet connection.
In the medical area the IoT allows new forms of patient monitoring. With the appropriate sensors on the body and a smartphone in the pocket certain vital parameters of sick people can now be continuously monitored in everyday life, without their having to stay in hospital or visit a doctor daily for this.
In such applications the IoT not only provides for a much higher quality of life but also reduces the treatment costs at the same time, so that the improvement in the quality of life is also of interest from the point of view of an economy-oriented controller. Such patient monitoring systems primarily use BLE and Wi-Fi for data transmission.
A diabetes management system essentially consists of a blood glucose meter, an app on a smartphone and a patient database in the Cloud. At intervals throughout the day measurements of the blood sugar level are recorded and transmitted to the smartphone by Bluetooth Low Energy (BLE). The patient can use the associated app to document other things such as food intake. They also receive advice and recommendations via the app about correct diet and fluid intake. The data are bundled together from the app and transmitted in encrypted form to a patient database. Professional medical personnel can then access these data and provide the patient with appropriate advice and notifications e.g. about the insulin dosage to be given. This system can also be supplemented by an automatic or semi-automatic insulin pump, attached to the patient's body.
Another example from the area of Personal Health & Fitness is the Activity Tracker or Activity Monitor. Numerous versions of these are now commercially available, from simple step counters to complicated sports watches, which measure the user's blood oxygen saturation and heartbeat. There are differences in the features and the precision. Most devices have one thing in common, namely a BLE connection to a smartphone, an associated app and/or an interface to the most popular fitness and running apps.
The data are usually sent by the smartphone to the Cloud in unencrypted form. By private arrangement these data can then be seen by friends. In these applications, unlike in the medical application, no great value is placed on the data security, since it is up to the user to decide whether or not to share his data publicly.
Also of interest is the networking of electrical energy storage devices and the newly planned business models of the energy suppliers. A business model provides, for example, for energy storage devices to be filled from various energy sources (solar, wind, bio, hydro…) several times a day (up to 3 times) and for the energy to be called up at peak times each day. The Smart Meter Gateway and the Smart Meter are absolute necessities for this.
Such a model is particularly appropriate in Germany for the owners of solar power systems which have come to the end of their feed-in compensation period who will now achieve a faster return on their investment in their energy storage devices under this model.
In Germany there are already 60,000 compensation schemes for private homeowners which are due to expire in 2018.
Since these installations are all still functioning well and generate electricity at the cost of their upkeep (ca.0.02 €) it is advantageous to install a storage device.
