Building technology is the part of a business that should just operate unobtrusively in the background. You only really notice it when there is suddenly a lack of compressed air in the value-adding processes, when the heating, air conditioning and ventilation system in the buildings is no longer functioning properly, when the separator tanks are full and so on.
The plants that are supposed to ensure optimal process conditions are very often ones that have reached a certain age. These plants do not necessarily have what is required to be connected to a digital building management system in a manner that would make sense economically. But how can the managers be made aware that there is a problem at one of these plants, especially when they are in such remote locations?
The KIS.devices have digital inputs and outputs. This allows them to be connected to machines and sensors. Since the devices are WLAN-capable, no additional routing of cables is necessary. The incoming data is sent to the KIS.MANAGER via the WLAN connection. The data can now be conveniently received and processed on the KIS.MANAGER web platform – with an Internet-enabled device that can be located anywhere.
The plant manager now decides what happens to the data in the KIS.MANAGER.
A water treatment plant located in the basement has a problem and shuts down. This machine state causes a signal to be sent to a digital input of a KIS.LIGHT. The KIS.LIGHT immediately transmits the signal to the KIS.MANAGER via WLAN. In this case, the plant manager has already determined what this signal should trigger. For example, the plant manager may have chosen to receive an automated e-mail. In addition, a visual signal is sent to a second KIS.LIGHT in the office to make the fault known as efficiently as possible.
Result: Ideally, the fault can be remedied before the missing medium is noticed in the value-adding processes, leading to production downtime.
In addition to information in acute cases, KIS.MANAGER offers the plant manager the option to keep an eye on plant states using digital twins and digital building maps. These states can also be evaluated and represented in clear diagrams.
The condensate tank of an air dehumidification plant fills up in cycles that are highly irregular, as the quantity that drips into it depends on the amount of water in the air. A retrofitted fill level sensor sends a signal to a digital input of a KIS.BOX before the container overflows. In this case, the manager has decided that the KIS.MANAGER is to send an e-mail to a chat in Microsoft Teams. This chat simultaneously informs the entire plant maintenance staff about the fill level of the container. The person who takes care of emptying the container sends a brief message to the others and goes to the container to empty it.
Result: The often unnecessary journey to check the fill level of the container is eliminated.
The information simply goes to where it is needed.
One of the most expensive media in production is compressed air. As a result, there is a desire to separate zones that do not require compressed air (weekend, end of shift, etc.) from the overall network.
To do this, you can either have someone go on site and close the corresponding tap or you can install a WLAN-capable KIS.BOX at key points in the system so that valves can be controlled via digital outputs. If this is the case, all the digital twins of the KIS.BOXes can be positioned on a building map on the KIS.MANAGER web platform and a few rules can be created. This is all that is required to digitally transform and clearly represent this medium. The building map provides an overview of which zones are currently switched on and which are switched off. The digital twins make it possible to use a computer or tablet to control connections and disconnections.
Result: The line losses and the distances travelled by the personnel are minimised, thus reducing energy costs and saving time.
All of the examples demonstrate how it is possible to make considerable improvements with simple measures and very little investment.
