Intelligent, automatic doors

The Swiss company record Group is one of the world’s leading manufacturers of automatic door systems. Together with Microtronics valuable experiences in the field of Internet of Things and a Proof of Concept were generated.

For maintenance and to get basic information about the automatic door, the service technician must connect directly on site via cable. This requires a complex task including unscrewing the door to get the necessary data. Anyone who has ever passed an unscrewed door, knows how unattractive and disturbing this is for potential customers.

In the Proof of Concept, the focus was on a quick implementation in order to generate experience under real condition according to the “Learning by doing” principal. Even if everything is technically possible, “because we can” is not enough to justify an IoT project. Measuring every second and observing the condition of the door live is not a technical challenge. But why?

Workshops were held internally and with customers and a discussion about the potential of the Internet of Things was opened. This communication and the Proof of Concept raised completely new questions for record Group. Security plays a central role at doors that can be accessed via the Internet. It would be inconceivable if the door could be opened by unauthorised persons from afar.

Therefore, a two-step process was provided for predictive and remote maintenance applications. Only after confirmation directly at the door the changes, that are made by the service technician remotely are actually forwarded to the door. The monitoring platform allows the doors to be managed online without too much technical knowledge.

The best practice of the record Group shows that an IoT project is always an innovation project. The most diverse interest groups have to be brought on board in order to ultimately generate added value and not simply record and collect data because it is possible.

The technology from Microtronics

With the rapidM2M module and a rapidM2M PoC CAN Shield the data of the automatic door were recorded directly via the CAN interface. Approximately 80 different parameters are supplied by one door. An elaborate protocol had to be implemented for this.

Among other things, the number of openings, error messages, drive-up speed and braking are recorded. The openings create a cyclical motion profile.

The end-to-end security of the Microtronics complete solution is suitable for such safety-critical applications. A variety of security mechanisms are already integrated in the system architecture. This includes for example memory to memory communication and AES 256 encryption.

In the Proof of Concept fast progress is relevant . The focus is on the MVP (Minimum Viable Product). This is easily possible with a PoC Shield. In order to minimize time, costs and risk, a complete onboarding or integration is often realized together with the customer in the next phase of an IoT project.
