Monitoring and remote query of sampling devices
Benefits for MAXX Mess- u. Probenahmetechnik GmbH
MAXX Mess- und Probenahmetechnik GmbH is one of the largest sampling device manufacturers world-wide. Water analysis and water quality are in the focus of MAXX.
When developing the portable device P6 L, the space for the complete data communication technology and the data logger was limited to the size of a few match boxes.
Moreover, it was necessary that the data in the data logger can be accessed via a browser that customers do not have to install a separate software for remote visualisation.
The following requirements to the cellular router are framed in the project:
The INSYS Smart Devices of the QLM series fulfil all requirements as single-board routers and have many additional benefits:
1. Monitoring of the cooling of stored samples
The portable sampling devices are inserted in sewer tunnels and cool the samples taken. The cooling temperature is monitored and failures are reported immediately.
2. Troubleshooting if required saves expensive routine inspections.
Failures in suction, purging or battery will be signalled via e-mail or SMS. Service technicians visit the sampling devices only if required. Routine inspections with road blocks are not necessary any more.
3. No customer software installation
The cellular router will be configured via a web interface. Costs for software installation and updates do not incur on customer-side.
4. Evaluation and visualisation in (!) the Router
The maxxwareConnect software is running in the sandbox of the embedded router in a secure Linux environment and visualises the measuring data on a web server – all you need for remote access is a browser.
5. Flexibility for special functions
Customer-specific programs and scripts can be realised quick and easy in the sandbox of the router.
6. Remote access via virtual display
Each customer can access the sampling device form anywhere using secure VPN connections and gets his familiar sampling device HMI “streamed” to his PC.
7. Cellular radio plus very high security standards
The QLM router has all security features on-board: e.g. an integrated firewall, encryption via VPN (OpenVPN, IPsec, PPTP).
8. Router, data logger and IPC in one device:
All modern communication protocols are supported besides the basic router functions. The sandbox makes additional controllers needless.
9. Development board for evaluation
INSYS icom provides a suitable development board as well as a free SW development environment with example programs and individual training.
“Our P6L must fit through a manhole in the street. We have planned space for a Linux board and an industrial PC in the housing – then we’ve found the embedded cellular router QLM of INSYS icom and are really very happy now.
We have router, web server, fault monitor, data logger and industrial PC space and energy conserving in one device now with the QLM.
Even the colleagues in the manufacturing department benefit from this since the space gained facilitates the assembly.
Even if it was “only” a question of space first for the P6L: We’ll offer the QLM router to all of our customers in each sampling device!”
