jamissüsteeme

Jamissüsteeme is a modular framework designed for the rapid integration of distributed sensor networks within industrial automation environments. It was first introduced in 2013 by Jami Technologies, a Finnish company specializing in plant control systems. The core aim of Jamissüsteemi is to standardize communication protocols, data formats and security policies so that heterogeneous devices can exchange information without custom adapters. The system is built around a lightweight message bus that supports both publish–subscribe and request–response interactions. Each sensor or actuator registers itself with the Jamissüsteemi registry, providing a description of its capabilities and data schemas. The framework then automatically generates a RESTful API endpoint, allowing legacy SCADA systems to access sensor values in real time.

Jamissüsteemi relies on a combination of OPC UA, MQTT and JSON‑Schema for data exchange, and includes built‑in support for TLS encryption, role‑based access control and audit logging. The architecture can be deployed on-premises or in the cloud, with a Docker‑based distribution making installation straightforward for operators. By abstracting low‑level communication details, Jamissüsteemi enables engineers to focus on higher‑level analytics and control logic.

In its early versions, performance bottlenecks were noted when handling more than ten thousand concurrent MQTT topics. These issues were addressed in the 2.0 release with an adaptive load balancing layer. Future development plans include native support for edge computing nodes and integration with predictive maintenance algorithms. Jamissüsteeme is licensed under an open‑source license, encouraging community contributions and interoperability with other industrial IoT standards.
