sent and protective rescue measures to be initiated. To achieve good results, a live
monitoring system must meet several requirements: It should be suitable for different use cases, be easy to use, mobile, ensure both the data protection of users, i.e. the employees and contractors in the operating facilities, and the security of the company data obtained.
CLOUD-BASED SOLUTION FOR DATA STORAGE AND PROCESSING Dräger’s live monitoring solution is a good example of how this works. Its centerpiece is Gas Detection Connect (hereinafter GDC). The Microsoft Azure-based cloud software can be networked with mobile gas detectors and a stationary area monitoring device; the data is transmitted live. The advantage of the cloud-based system is that all relevant information is available right where it is needed. The devices can also be managed efficiently from any location using remote access. Live monitoring with GDC is
suitable for various applications. In conjunction with a smartphone app, it can protect employees or contractors who work alone (lone workers), for example during inspections outside business premises. In these cases, the app on the smartphone connects via Bluetooth to a portable, wearable, gas detector. This transmits the device data such as gas or a panic alarm which then becomes available in the cloud. In addition to alarms and gas measurement data, the employee’s location is also transmitted. Data privacy issues must therefore be clarified before use.
LARGE AMOUNTS OF DATA FACILITATE HAZARD ANALYSIS When it comes to obtaining data from industrial areas in which several employees or contractors are working at the same time, for example for maintenance and repair work, live monitoring can be carried out with the explosion-proof Dräger ConHub. The portable gateway can transmit data from up to 20 personal gas detection devices located within its

range to the cloud. To do this, the gas detectors connect to the ConHub via Bluetooth. The position detection with built-in GPS makes it possible to assign the individual devices to the respective position of the ConHub – without transmitting a person’s specific location. An advantage is that no SIM card
mobile device (direct to cloud) is required here. The background to this is that these devices are dependent on constant Broadcom connectivity. Shadow effects in dense industrial areas can lead to network problems. All the gas detection devices that
can connect to the ConHub at the same time can provide large amounts of data, providing a deeper insight into potential danger zones. On the one hand, the data makes it easier to take suitable measures in good time, for example in the event of an accident. On the other, the analysis of the collected data allows conclusions to be drawn about the hazard potential of monitored areas and can therefore contribute to hazard prevention.
The complexity of operating
facilities in the process industry is constantly growing. At the same time, the demands on both plant performance and compliance are also increasing. Overcoming these challenges will only be possible through the consistent integration of technologies such as IIoT and cloud computing, which can deliver and process large volumes of data within a facility. The aim must be to further develop
existing solutions in this field based on specific customer needs and requirements and to always use the most meaningful data to ensure that the process industry remains safe, efficient and future-proof. Overall, the security of the data should have the highest priority. To ensure this, Dräger is taking various measures.
