AMQP-based subscription group message delivery system design for laboratory safety system

Abstract

Laboratory safety management system is a system that uses the data collected from various sensor devices to detect risk situations and send risk alerts to the required devices. However, since the pre-existing system has different sensor devices connected to the gateway, it requires the standard communication protocol to be introduced. In addition, due to the low process performance of the IoT sensor device and the unstable wireless environment, the pre-existing protocol inevitably involves unnecessary header and complicated processing. Due to these reasons, it is quite insufficient to apply such pre-existing protocol to the safety management environment where various sensor devices are connected. In this thesis, based on the standardized AMQP, the MQTT protocol more lightweight than the pre-existing protocol was used to propose the laboratory safety management system that allows a topic-based group message delivery between sensor device and service. It is determined that using AMQP, a standard protocol, conveniently transplantable into diverse platforms will allow networking among diverse sensor devices, and that using the topic-based message queue will allow prompt and efficient sensor data transfer among various services.
