“…Here are some works that have proposed some solutions for partial objectives covered by the SmartFire prototype. Park et al proposed the measurement of pressure gauge using color segmentation for the safety management of fire extinguisher [16]. The main idea is that pressure gauge includes a green color indicating the normal pressure.…”

Due to fire protection regulations, a minimum number of fire extinguishers must be available depending on the surface area of each building, industrial establishment or workplace. There is also a set of rules that establish where the fire extinguisher should be placed: always close to the points that are most likely to be affected by a fire and where they are visible and accessible for use. Fire extinguishers are pressure devices, which means that they require maintenance operations that ensure they will function properly in the case of a fire. The purpose of manual and periodic fire extinguisher checks is to verify that their labeling, installation and condition comply with the standards. Security seals, inscriptions, hose and other seals are thoroughly checked. The state of charge (weight and pressure) of the extinguisher, the bottle of propellant gas (if available), and the state of all mechanical parts (nozzle, valves, hose, etc.) are also checked. To ensure greater safety and reduce the economic costs associated with maintaining fire extinguishers, it is necessary to develop a system that allows monitoring of their status. One of the advantages of monitoring fire extinguishers is that it will be possible to understand what external factors affect them (for example, temperature or humidity) and how they do so. For this reason, this article presents a system of soft agents that monitors the state of the extinguishers, collects a history of the state of the extinguisher and environmental factors and sends notifications if any parameter is not within the range of normal values.The results rendered by the SmartFire prototype indicate that its accuracy in calculating pressure changes is equivalent to that of a specific data acquisition system (DAS). The comparative study of the two curves (SmartFire and DAS) shows that the average error between the two curves is negligible: 8% in low pressure measurements (up to 3 bar) and 0.3% in high pressure (above 3 bar).

Pressure gauge calibration refers to comparing the standard and test gauge to determine the error percentage. The reading accuracy of the analog dial pressure gauge is found in the conventional method through manual calculations and then tabulating the values in the calibration certificate. The present study is undertaken to increase the accuracy level of the analog dial pressure gauges. A new automated computer-based method is proposed to calibrate the meters more accurately than the conventional method. The indicated value of the pressure gauge is obtained through the angular position of the pointer and the error value is identified by comparing both standard and test gauge values. In this work, Red, Green, Blue (RGB) images of standard and test pressure gauges are acquired through a high-definition camera. After the image processing operations, the pointer orientation of the indicatoris identified, and the indicated values are calculated. The computer-vision-based automatic calibration system is applied in a 0–100-psi (0–689.476 kPa) analog dial pressure gauge, and three trials were performed to determine the accuracy. The computer vision technique improved accuracy, varying from 97 % to 98 % compared with the conventional manual observation method. The observed results have improved repeatability and accuracy with the proposed computer-vision-based system.
