IoT-Based Protection of Ventilation and Air Conditioning Units in Chemical Industry

摘要

In this industrial world, the dependence on the chemicals for the growth of the nation has become evident from the looming of more chemical industries. As a result, there has been more and more case of chemical disasters both in developed and developing countries. The disaster is due to the failure of the conventional secure system, which is based on Wi-Fi, and many times, it becomes unreliable during the unfortunate event of disaster. This project aims to provide a safe environment during emergency situations by an automated response and a means to communicate the information of the disaster immediately so that the impacts of it can be reduced. Present technological advancements such as Global System for Mobile communication (GSM), General Radio Pocket Service (GPRS) have been utilized in the communication of the disaster informations through Internet of Things (IoT). Also, the primary focus of the project is to make a building-independent monitoring system so that the loss of connectivity does not occur due to the damage in the building. Further, the real-time sensor data will be transferred to the IoT server via GPRS connectivity. The real-time values are sent to IoT through API by using the GPRS connection on the GSM module. The data logging can be separated channel wise and more actions can be programmed on the IoT platform through MATLAB. The system deals with monitoring and controlling the working environmental conditions like carbon monoxide, methane, hydrogen, LPG and flammable gases with sensors and using Arduino to make a decision as per preprogrammed also send this data to the cloud server and draw the sensor data as pictorial statistics. The data upgraded from the enforced system is accessible within the Web from anywhere within the world. The automatic venting off the toxic gases from the working premises immediately after the detection and without waiting for the communication from higher position, which makes the lesser impact on worker's life that is unaware of consequences of the accident.
