Retrofit for existing buildings
In existing buildings, extensive retrofitting of sensors is also made difficult mainly due to complex cable routing.
Frequently recurring tasks:
- Flexible usage of sensors (positions, types, number)
- Subsequent or additional installation of sensors
In all these cases, the use of wireless sensors is a convenient, fast and flexible way of integration.
Expansion: Air quality measurement for offices
Due to the already installed LoRaWAN infrastructure, it was possible to retrofit the offices and meeting rooms in the administration buildings with an air quality measurement and to integrate this into the system as well. In addition to temperature and humidity, fine dust, CO2, ozone and formaldehyde content of the room air are also measured in the administration rooms.
This function in particular proved to be a very helpful tool for implementing a CO2 traffic light during the Corona pandemic.
Work with data streams
VISAM relies on modern IoT infrastructures such as LoRAWAN networks to connect the sensors. On this basis, local networks are established and data is collected for visualisation and logging.
Although designed and applicable as a wide-area network, LoRa networks can also be configured as so-called campus networks by integrating local or "private" networks, in which the area of usage is restricted to single project (grounds or larger building complexes).
The data streams from the sensors are collected by locally installed LoRA gateways and are transmitted to a VBASE server system. All incoming data is checked, visualised locally and updated in databases. In addition to checking limit values for undercutting or exceeding, the VBASE server also permanently monitors the battery voltages of the transmitters and the cyclical transmission of the data. In case of deviations, alarms or messages are generated and automatically transmitted (local alarms, email, GSM, messenger). The recorded data (histories) can be flexibly retrieved and exported to common file formats for further processing and optionally sent automatically.
Since a large number of IoT sensors and actuators are now available, there are hardly any limits to applications in many other areas, such as energy data acquisition or air quality monitoring. This technology also offers immense advantages in the area of modernisation, especially of larger complexes.
