OPEN SOURCE MAGICDRAW ARCHITECT SOURCE CODE SOFTWARE
OpenMBEE software is licensed under Apache 2.0 or another compatible open source license. This supports the idea to create a unified environment based on a variety of commodity software. Another distinctive quality is that the open source software on OpenMBEE includes plugins or extensions for commercial tools. The intent is that more open source models and model libraries will flourish as the community grows. OpenMBEE has a variety of open source projects supporting this pursuit as well as contributed open source models.
The core concept is to use transclusion technology to create unified technical information with an authoritative source. Such environments inherently serve multiple modeling languages as well as a variety of techniques for model checking, simulation, document generation etc. The concept is to create an integrated environment for engineering that is driven around connected models. OpenMBEE is an open community built around an open source Model-Based Engineering Environment. The purpose of an end-application could be analytics, alerting, data visualization, triggering actions. It can use the ChirpStack Application Server API in order to schedule a downlink payload to the devices. The end-application receives the device-data through one of the configured integrations.
Received uplink data is forwarded to one or multiple configured integrations. It provides a web-interface and APIs for management of users, organizations, applications, gateways and devices. The ChirpStack Application Server is a LoRaWAN Application Server, compatible with the ChirpStack Network Server. When an application-server needs to send data back to a device, the ChirpStack Network Server will keep these items in queue, until it is able to send to one of the gateways. When data is received by multiple gateways, the ChirpStack Network Server will de-duplicate this data and forward it as one payload to the ChirpStack Application Server. It has knowledge of device activations on the network and is able to handle join-requests when devices want to join the network. The ChirpStack Network Server is a LoRaWAN Network Server, responsible for managing the state of the network. It also provides integrations with various cloud platforms like GCP Cloud IoT Core and Azure IoT Hub. It transforms the Packet Forwarder format (like the Semtech UDP Packet Forwarder protocol) into a data-format used by the ChirpStack components. The ChirpStack Gateway Bridge sits between the Packet Forwarder and MQTT broker. Common implementations are the Semtech UDP Packet Forwarder and the Semtech Basic Station Packet Forwarder. The software running on the LoRa Gateway responsible for receiving and sending is called a Packet Forwarder. LoRa ® GatewayĪ LoRa Gateway listens to (usually) 8 or more channels simultaneously and forwards received data (from devices) to a LoRaWAN network-server (in this case the ChirpStack Network Server). These devices could be for example sensors measuring air quality, temperature, humidity, location. The LoRaWAN devices (not pictured in the above graph) are the devices sending data to the ChirpStack Network Server (through one or multiple LoRa Gateways). The graph below visualizes how the ChirpStack LoRaWAN ® Network Server components are connected: (Geolocation Server) (Geolocation Server).ChirpStack architecture ChirpStack architecture Table of contents.ChirpStack open-source LoRaWAN ® Network Server
