Abstract: Disclosed is a portable poisonous gas monitoring apparatus including a gas sensing unit having a structure capable of being detachably attached to a work site or a worker, the gas sensing unit being configured to generate gas sensing information as the result of sensing poisonous gas, a worker sensing unit having a wearable structure capable of being worn on a portion of the body of the worker, the worker sensing unit being configured to generate life support information of the worker, a relay unit configured to receive and relay the gas sensing information and the life support information through RF communication, and a portable monitoring unit configured to receive the gas sensing information and the life support information from the relay unit through RF communication and to monitor the state of poisonous gas and the condition of the worker.

Abstract: A smart fire detector according to the present invention includes a sensing unit configured to detect one or more fire elements, a controller configured to analyze sensing signals detected by the sensing unit to determine whether a fire has occurred and to output a fire signal upon determining one or more of the fire elements to be a fire, an imaging unit configured to take an image of an area in which the fire elements have been detected according to the fire signal and to extract an image and a picture of a high-definition snapshot from the taken image, and a notification unit configured to output a fire alarm and near fire escape route guidance sound according to the fire signal. Accordingly, the present invention can notify not only of a fire but also of a detected fire element for each type through analysis of a detected fire element.

Abstract: Disclosed is a sensor for receiving power from the outside and measuring data on a current state. A smart safety management sensor for measuring safety-related data of a structure includes a detection module installed in a structure and configured to detect a state of the structure at a preset interval, a control module operatively associated with the detection module and configured to calculate a result value based on data received by the detection module, and an output module operatively associated with the control module and configured to receive a result value calculated by the control module and to provide information to a supervisor.
